This year’s dog days have started.

Under high temperature

Many people are busy "drying their backs"

Is this really for health?

01

Can basking in the back really keep fit?

Doctor: Don’t blindly follow the trend!

It is said that "sunbathing on the back in dog days" mentioned by netizens can expel the latent evil in the body, which can not only drive away the cold and keep warm, but also relieve depression, improve physical fitness and improve skin color.

Is back drying really effective? Some netizens said that they did see the effect.

Some netizens said that improper sunbathing can easily lead to heatstroke and sunburn, and not everyone’s physique is suitable.

Some people don’t quite understand "basking in the back". Is it uncomfortable to stay in an air-conditioned room?

The doctor reminded: Don’t blindly follow the trend!

Zheng Yanhua, deputy director of the Department of Traditional Chinese Medicine, Panyu Campus, the Second Affiliated Hospital of Guangzhou Medical University, said that many meridians and acupoints are on the back, and drying the back can regulate the qi and blood of viscera. People with deficiency cold constitution, excessive cold and dampness, frequent diarrhea, cold hands and feet, and fear of cold, try to bask in the back properly or help relieve it.

However, Zheng Yanhua reminded that there are still many stresses on sun-drying health care, and you can’t blindly follow the trend. Sun-drying health care has these stresses:

one

When and how long is the sun suitable?

7-9 am, or after 3 pm.

Adults should spend 20 minutes to 1 hour in the sun each time; Because of the delicate skin of infants and children, the sun exposure time can be appropriately shortened to 15-20 minutes; The ability of the elderly to synthesize and use vitamin D is reduced, and the time can be appropriately extended, but they should not be exposed to the sun for too long at a time.

Sunbathing can achieve slight sweating, not sweating and mental irritability. The first sunbathing time can be shorter. If you feel comfortable, you can extend the time slightly, or do it several times.

2

What are the precautions for drying your back?

Don’t dry your back on an empty stomach. You should take sun protection measures on your head, face and eyes, such as wearing a sun hat and sunglasses. You’d better wear a light-colored blouse when drying, and drink water properly before and after drying to supplement body fluid consumption.

You can prepare sour plum soup, mung bean soup and light salt water at room temperature, and carry warm water and heatstroke prevention and cooling drugs in case of emergency.

It’s best to stay behind the sun in the shade to avoid strong winds and cold winds. If you sweat too much, wait until the sweat stops before entering the air-conditioned room.

three

Who are not suitable for drying their backs?

People who are allergic to ultraviolet rays, or people with hypertension, hyperlipidemia, diabetes, coronary heart disease, people with deficiency of both qi and yin or people with yang excess, pregnant women and other people are not suitable for sun drying.

In addition, older people should also be cautious, and it is best to pay attention to various details accompanied by family members to avoid discomfort.

four

Do enough sun protection after eating these foods and medicines.

Avoid sun exposure after eating or touching Chenopodium album (grey vegetables) or other plants with photosensitivity. Common photosensitivity foods include figs, spinach, lettuce, buckwheat, Chinese cabbage, mustard, amaranth and purslane.

After taking drugs that are prone to phototoxic reaction, you should avoid exposure to sunlight or ultraviolet rays during taking the drugs and within 5 days after stopping taking them. The incidence of phototoxic reaction is higher in the class of antibacterial drugs, such as ciprofloxacin, ofloxacin and enoxacin. In addition, tetracyclines and sulfonamides have also been reported in phototoxic reaction.

Therefore, it is recommended to read the drug instructions carefully before taking the drug, especially when it is indicated in the instructions that the drug can cause phototoxic reaction, you should take good sun protection measures, such as applying sunscreen before going out, wearing umbrellas, sunglasses, trousers and long sleeves to avoid direct exposure of the skin to the sun.

About dog days

These rumors need to be vigilant!

Every year, some people blindly keep in good health. The following are some common rumors to clarify:

one

Detoxification after sweating in the dog days?

When the weather is hot, such as dog days, people sweat to better dissipate heat. It is a normal physiological phenomenon that the skin releases heat and regulates body temperature through sweating.

However, excessive sweating and water loss are prone to dehydration and even heatstroke. In the theory of traditional Chinese medicine, there is a saying that sweat and blood are homologous, which means that sweat is transformed from body fluid, and both body fluid and blood come from the subtle grains (nutrients) transported by the spleen and stomach. When sweat is too outdated, its blood will be deficient.

Therefore, sweating slightly is enough, and timely summer vacation is the right solution.

2

Can’t touch iced drinks in the dog days?

Many people may have heard that you can’t touch cold drinks in dog days. In fact, it depends on your physique.

If it is a hot constitution, you can drink ice water or cold drinks in moderation; If you are deficient in cold constitution, you should try to drink warm water or cool white water in hot days.

Need to be reminded that no matter what constitution, excessive drinking of cold drinks will affect the health of the spleen and stomach. Even if the weather is particularly hot, you need to sip slowly when drinking cold drinks.

three

Should heat be used for health preservation in dog days?

In the dog days, "heating with heat" actually refers to nourishing yang in summer, and the best effect is to pursue victory and nourish yang in the solar terms with the highest yang.

However, "heating with heat" is not just hot. You can change iced drinks into warm or normal temperature herbal tea and take a bath with warm water instead of a shower.

four

Carry Huoxiang Zhengqi with you to prevent heatstroke?

The main functions of Huoxiang Zhengqi Water are relieving exterior dampness, regulating qi and regulating middle warmer. It can treat fever, chest tightness, abdominal distension, vomiting and diarrhea caused by moisture in hot days, and nausea and vomiting (summer-damp cold) caused by excessive dampness.

Huoxiang Zhengqi Water is not used to prevent heatstroke, but to treat summer-damp cold. If you want to prevent heatstroke, stay away from the high temperature environment, take the initiative to cool down, and replenish water and electrolytes.

five

Summer training is suitable for everyone?

Practicing dog days in summer is a traditional method of keeping in good health, which means strengthening the body’s heat resistance and preventing heatstroke and other diseases through proper exercise in the hottest summer. The main purpose is to improve the body’s adaptability to the environment through exercise.

However, dog days are characterized by high temperature and high air humidity, so "practicing dog days in summer" requires skill:

Time: the dog days are long, so you can go to bed late and get up early in work and rest, and it is best to choose early morning or evening when the temperature is relatively cool;

Exercise: Swimming, yoga, Tai Ji Chuan and other sports are recommended, which can not only strengthen the body, but also do no harm to the body due to excessive exercise.

03

Correct dog days regimen

Save it in favorites immediately

one

Drink more hot tea.

Chinese medicine believes that health care should conform to the season, and it will be hot when it is hot in summer, and it will be sweaty when it is sweating. In dog days, we should follow the seasonal law and use the "heat-keeping method" to heat up and cool off the summer heat healthily.

2

Have some hot food

As the saying goes, "Eating radish in winter and ginger in summer does not require a doctor to prescribe". Ginger helps to warm the middle and dispel the cold. In addition, cinnamon and fennel can be used as isothermal seasonings in summer.

Hot meats such as mutton and beef can also warm yang and dispel cold, especially suitable for people with cold hands and feet and insufficient blood in summer. People with toothache, excessive internal heat, fever and other symptoms, or people with a hot constitution should avoid eating.

three

Washing hot water

Taking a bath with hot water will dilate the capillaries of the body, which is beneficial to heat discharge. The water temperature is generally controlled at about 30℃, and you can also wipe your face and body with a hot towel to help your body sweat and cool down and make your skin breathable.

four

Hot water soaking feet

Foot is the second heart of human body. Soaking feet with hot water can make blood flow smoothly, increase the blood flow rate and flow rate of feet and enhance metabolism. When soaking feet, the suitable water temperature is 42 C-45 C, and it is appropriate to be warm and comfortable.

five

Do moxibustion

Chinese medicine believes that moxibustion in dog days will get twice the result with half the effort. When moxibustion is applied, you sweat moderately, and the heat and dampness in your body are also discharged. Drink some warm mint leaf water after moxibustion, and your body will feel extremely refreshed.

six

Sweat properly

In summer, it is necessary to "control sweat with sweat", and exercise is an important way to sweat. Exercise can also strengthen heat adaptation, improve the body’s function of regulating body temperature and prevent heatstroke.

You can choose jogging, Tai Chi, walking, swimming and other less strenuous exercise methods. It is recommended to exercise in the morning or evening to avoid sweating and hurting qi and blood.

04

Do these things

Cool off the summer and get comfortable in the dog days.

If you feel sweaty and lose your appetite in summer, try the heat-relieving method recommended by experts, and you can "naturally cool" without turning on the air conditioner to the maximum.

1. A small amount of water for many times

Drink plenty of water in summer, but be careful not to add a lot of water (more than 500 ml) at a time. It is recommended to drink one or two glasses of water first, and then drink every half hour. The water temperature should not be too hot or too cold.

2. Eat "bitter" appetizers

It is easy to lose appetite when you enter the dog days, so you can eat more bitter food, such as bitter gourd and bitter chrysanthemum. Chinese medicine believes that suffering into the heart can clear the heart fire and is conducive to nourishing the heart in summer. Bitter gourd is cold, and people with poor constitution and deficiency of spleen and stomach should not eat more.

3. Don’t be too greedy

Too cold air conditioning can easily cause a variety of discomfort, so it is best to adjust it to about 26C, or ensure that the temperature difference between indoor and outdoor exceeds 7 C. Let the air conditioner blow upward, avoid blowing directly on the body, and focus on protecting the neck, back, abdomen, waist and knees.

Don’t take a cold shower after sweating profusely. Try to eat as little cold drinks as possible. If you must, it is best to eat between noon and 3 pm.

4. Choose cotton and linen materials for clothes.

The material of clothes will affect the evaporation of sweat. It is recommended to use cotton, linen, silk and other materials that are loose and hygroscopic, or to choose synthetic fiber materials with strong permeability.

5. Go to bed late and get up early

Going to bed late is not advocating staying up late, but working on time according to the characteristics of day and night changes in summer. It is better to fall asleep before 11: 30 in the evening and get up at 6 or 7 in the morning. You can take a nap for 30-60 minutes at noon, which is beneficial to the balance of qi and blood and helps to replenish your physical strength.

Step 6 be calm and cool naturally

In hot and humid weather, people are prone to signs of "emotional heatstroke" such as upset and listlessness. Sitting still, watering flowers, reading, listening to music, etc. are all helpful to relieve irritability.

Two years ago, Alibaba and JD.COM, the first and fourth largest Internet listed companies in China, respectively joined hands with Suning Yunshang and Yonghui Supermarket, and their transformation from "electricity" to "store" was regarded by the outside world as the horn of e-commerce bosses to go offline.
　　Arribe cast a dense net. In November 2016, Sanjiang Shopping Announcement introduced Alibaba Zetai as its strategic investor, with an investment of 2.15 billion yuan. If Hangzhou Alibaba Zetai converts all exchangeable corporate bonds into shares, the shareholding ratio can reach 35%.
　　In December 2016, Yiguo Fresh, which was invested by Ali, "took over" 237 million domestic shares of Lianhua Supermarket sold by Yonghui Supermarket (accounting for 21.17% of the total share capital of Lianhua Supermarket) and became the second shareholder of Lianhua Supermarket. Bailian is still the controlling shareholder of Lianhua Supermarket, holding a total of 42.73% of its shares.
　　In January 2017, Yintai Commercial announced the privatization, in which Ali participated and will become its controlling shareholder with a shareholding ratio of 74%.
　　In February 2017, Alibaba and Bailian Group announced a strategic cooperation.
　　Similarly, JD.COM’s actions are actually quite a few.
　　In June 2016, after JD.COM acquired No.1 Store, it started in-depth cooperation with Wal-Mart behind the latter. Wal-Mart will provide rich commodities through its global supply chain, and its physical stores in China will be connected to Dada, a crowdsourcing logistics platform invested by JD.COM and JD.COM.
　　It is not difficult to see that the retail industry is quietly storing the kinetic energy of change.
　　According to Chen Weihao, a partner of Huaping Investment, new retail has two main components: the first is the change of consumption demand of a new generation of consumers. Now the mainstream consumers after 70-90 are completely different from the previous generation. They pay more attention to product quality and service, personalization and technology, and at the same time, they have more disposable income and time. Under such circumstances, how can we meet the consumer demand? This is what the retail industry needs to respond to now.
　　The second point is technological innovation. For example, he said that few people used Alipay three years ago, and there was no WeChat payment. E-commerce began to rise on the PC side, and the real O2O has not yet begun. The smart phone has brought an earth-shaking change to the whole mobile Internet. All these new retails are good for technology and consumers’ information collection and feedback, all of which are achieved by the further development of Internet technology.

On October 13th, 2016, at the Alibaba Cloud Habitat Conference, Ma Yun first put forward the concept of "new retail" in his speech. Ma Yun asserted that "the era of pure e-commerce will soon end. In the next ten or twenty years, there is no such thing as e-commerce. Only new retail, that is, online and offline and logistics must be combined, can a real new retail be born."
　　The new retail concept was quickly accepted. All the giants in the retail industry will no longer talk about e-commerce and online shopping in 2017, but will advance on the new retail road. Fresh goods have always been the category that consumers buy the most frequently, and it seems logical for "new retail" to land here.
　　In January 2016, Hou Yi, the former director of Jingdong Logistics, founded Boxma Xiansheng in Shanghai, and later received a high investment from Ali. Boxma Xiansheng adopted the business model of "online e-commerce+offline stores", and the functions carried by the stores further increased compared with traditional retail, integrating "fresh supermarket+catering experience+online business warehousing". It is generally believed that Boxma Xiansheng will become the No.1 project of Ali’s new retail. Up to now, Boxma Xiansheng has opened 13 stores covering Beijing, Shanghai and Ningbo.
　　JD.COM is naturally unwilling to wait and die. In early 2016, JD.COM Fresh Food Division was established to accelerate the expansion of fresh food categories, quality control and cold chain logistics. Just after the Spring Festival in 2017, JD.COM set up a "secret force" outside the fresh food department. This organization is to do preparatory work for the development of offline fresh food stores in JD.COM. It is reported that the location of the offline fresh food store in JD.COM has been preliminarily determined: the first store is located in Yizhuang Dazu Square near JD.COM headquarters, with a business area of 4,000 square meters, and the second store is located in Wucai City, Qinghe Middle Street, Haidian District, with a business area of about 2,000 square meters.
　　JD.COM’s own new retail boots have not yet landed. On July 19th, the first store of "octopus (octopus) fresh", a new online and offline integrated retail format led by Meituan, officially opened.
　　Regardless of whether Meituan and JD.COM are benchmarking with Ali’s Boxma Xiansheng in the industry, this online and offline integration model can prove to some extent that new retail has been deeply cultivated from the past conceptual stage.

The cost of online traffic is getting higher and higher, while the proportion of commercial property leasing cost in the total cost of some physical retailers has dropped to less than 10%, and the gap between online and offline customer acquisition costs is narrowing or even reversing. Therefore, the continuous growth of pure e-commerce enterprises needs to rely on the integration and penetration of physical retail, and online and offline move from division to integration.
　　Xue Yu, senior analyst of IDC China, said that the continuous improvement of user experience and operational efficiency is the core requirement for business transformation, and the trends of standardization, interactivity, integration and globalization will become the main features of the "new retail" era. The core of new retail is the supply chain and ecosystem formed with consumers as the center.
　　Online is virtual, seemingly ethereal, and killing people is invisible; The offline is the truth. Although it is heavy, the knife is deadly. In the past, e-commerce enjoyed the benefits of online traffic, but ignored the fact that everyone was offline traffic before becoming online traffic, and offline traffic still had a lot of potential to be tapped, and offline also had many incomparable advantages online.
　　The new circulation is to serve the new consumer demand and guide the changes of the upstream industrial chain through the satisfaction of consumer demand. According to the reporter’s understanding, it is generally believed in the industry that the advantages of offline Shangchao have always focused on the satisfaction of customer experience. In the future competition, physical retailing will face more challenges focusing on how to manage users well and complete the changes in the new retail era through social networks, big data and logistics.
　　"E-commerce has inherent technological advantages under the transfer line. All innovative models are based on technical support, and the concept is also one of the advantages. The so-called concept is that the previous circulation is the terminal channel of production enterprises, but the new circulation form is for consumers, with the consumer demand as the core, because there is big data behind it." Li Mingtao, Dean of China International Electronic Commerce Center Research Institute, told reporters. The era of pure e-commerce will soon end, the form of pure retail will also be broken, and new retail will lead a new business model in the future.
　　Cao Lei, director of China E-commerce Research Center, once said: "In the past, online and offline retailing was in a state of’ with you and without me, with me and without you’. However, since last year, the integration of online and offline, from O2O to new retail, has become a broad consensus in the industry. Everyone began to think about complementing each other’s advantages, jointly doing a good job in product and service experience, and jointly dividing this cake, not just competition. "
　　Anxin county is rich in water resources. Baiyangdian Lake in Anxin County is an important water conservancy hub of Daqing River system, with an average total water resource of 41.24 million cubic meters for many years. The aquatic organisms in Baiyangdian Lake include plankton, benthos, fish and aquatic plants. At the same time, there are 26 species of birds belonging to 19 families, forming a good food chain structure and becoming an important aquatic product base in North China.

In order to truly replace the traditional retail model, "unmanned supermarket" must be better than "manned supermarket" on the basis of the existing model. So what does it take to be better than "someone"? Where are the benefits to consumers? Do we really need nobody?
　　In the short term, "unmanned supermarket" is difficult to replace the traditional retail business model, but intelligent supermarket is an inevitable trend of retail industry. Now it can occupy a place in the market by satisfying people’s curiosity, but to completely replace the traditional retail model, it is necessary to keep up with the rapid development of science and technology and study a better technical support and service model.
　　However, if only the hot concept hype of "unmanned supermarket" appears, it will be dispersed in a hubbub after the bubble is set off, and a new industry will not actually be formed. Then this technical concept of no hard goods is even more out of reach from the real retail reform.
　　"Unmanned supermarket" is indeed one of many possibilities for the retail industry in the future, but now, it is still far from enough.

[Global Network Automobile Comprehensive Report] On April 18, 2023, Lectra Motor landed at the 2023 Shanghai International Auto Show with its entire new energy lineup. As the latest masterpiece of Lectra Auto in the exploration of new energy travel, the intelligent five-seat ultra-electric SUV Lectra 08 comes with "electricity", and the EM-P super extended-range electric scheme based on CMA Evo’s new architecture is released, which accelerates the strategic transformation of Lectra brand to new and electric power.

At this auto show, the gold medal booth of Lectra’s "Urban Amusement Park" was advanced again. Inspired by the 24-hour changing urban landscape, the brand concept of "not just cars" was interpreted with a scene and immersive sensory experience. In addition, the prototype concept car of Lectra 08-The Next Day concept car was unveiled at the same time. It is an important carrier of Lectra’s new energy technology and an advanced interpretation of Lectra’s urban aesthetic design language, presenting the unique beauty of Lectra’s new energy.

The LECK EM-P super extended range electric scheme is advanced, and it is more electrified.

Aiming at the high-end experience of users, Lectra CMA architecture ushered in a new evolution-CMA Evo architecture. This is a new starting point for the new energy architecture to build a car, and it will fully empower the company to be new, electric and strong in the future.

Based on CMA Evo architecture, LEEK 08 released the EM-P super extended range electric scheme. This is an advanced new energy solution based on Lynk E-Motive intelligent electric hybrid technology platform, which is mainly driven by electricity, and can meet the needs of users in all scenarios and working conditions.

The EM-P super extended-range electric scheme supports three-motor four-wheel drive, including a brand-new independent rear-drive motor, and also supports the layout of super-large flat-panel batteries, which improves the inductance, performance, driving control and battery life of the GM EM-P model to a higher dimension and provides users with the optimal solution of new energy with more electrification and no anxiety in power consumption.

Linke 08 inductance crosses the border to open a new experience of charged travel

As the first strategic vehicle model born under CMA Evo framework and the first vehicle model of EM-P super extended range electric scheme, LECK 08 bears the heavy responsibility of LECK’s all-round new direction and reshaping the market structure. With the blessing of new architecture and ultra-electric scheme, Linke 08 expands the boundary of new energy travel with the hard-core strength of inductance, space, intelligence and design, and unlocks the new experience of "live" travel.

Relying on the EM-P super extended-range electric scheme, Linke 08 has a brand-new inductive driving pleasure of "one power to the end". The 3-motor 4-wheel drive version of LINKE 0800 kilometers accelerated into the "4-second club", with a comprehensive power of over 400kW and a maximum torque of over 900N·m, truly achieving high speed, long distance and off-road panic, showing the driving pleasure of "not only instantaneous explosion, but also full of stamina".

In addition, the 39.6kW·h ternary lithium flat battery+85kW DC fast charge, so that the LEICK 08 "has no worries about electricity use", and it can really charge for half an hour and commute for a week, even at MINUS 20℃. Linke 08 can also be transformed into an "energy fortress", which can provide more than 200kW·h of electricity when it is full of oil and electricity, and realize the freedom of electricity use; At the same time, it is equipped with 3.3kW external discharge function, which can be externally connected with various plug-in equipment, and can easily cope with various outdoor power occasions.

Thanks to CMA Evo’s stronger bandwidth capacity and flatter motorized chassis, the Lectra 08 has a wheelbase of 2,848mm, a car width of 1,915mm and a rear legroom of 935mm, which can be freely stretched regardless of the front and rear rows. The spacious space, combined with the advanced configuration such as the main driver’s independent headrest speaker and shallow seat, can realize the cross-border experience enjoyed by all seats.

While enhancing the breadth of the interior space, Linke 08 pays more attention to the details to let users feel the space temperature, and integrates advanced technologies such as natural air conditioning, streamer ambient light and Harman Kardon 23 speaker to create a zero-pressure lounge, which enhances the security, comfort and pleasure of intelligent interaction and brings users the most atmospheric "third space".

Today, with no intelligence and no electricity, Linke 08 relies on the new electronic and electrical architecture to open up the cockpit domain and the intelligent driving domain, bringing a highly customized, personalized and cross-terminal brand-new intelligent experience. Antola 1000 Pro computing platform+LYNK Flyme Auto’s "King-Bomb Combination" and the super-strength of NPU 16TOPS(int8) and GPU 1800G(FLOPS) make the cockpit experience of LINKE 08 start with the ceiling, creating a super unbounded ecology of real "handcart interconnection".

In addition, Linke 08 is also the first mass-produced car in The Next Day design language, which crosses the boundary between automobile intelligence and aesthetics and creates a new realm of urban opposing aesthetics. The 92-inch unbounded AR-HUD and other industries pioneered the use of pioneer technology, fully demonstrating the perfect integration of technology and design, and leading the aesthetic trend of smart cars with the beauty of technology.

Link’s new energy strategy, charged evolution, continues to change mobile travel.

Since its establishment seven years ago, the brand has always adhered to the brand spirit of "challenging convention" and continuously changed mobile travel; With the trend of "not just cars", it resonates with users around the world on the same frequency. At present, there are more than 860,000 car owners and users. "Link" is no longer just synonymous with a car and a brand, but a way of life and an expression of personality spirit.

Facing the wave of new energy travel reform with unlimited imagination, Linke insists on being the leader of the industry, not the follower of competitors. We will evolve smart electricity into a new track, meet the diverse needs of users through a variety of energy solutions, let travel get rid of dependence on a single energy source, and let users not be anxious, uncompromising and entangled!

The hybrid layout of Lectra has a long history. As early as 2018, Lectra has launched hybrid models. In June, 2022, LINKE smart electric hybrid Lynk E-Motive came from electric power, which provided users with a safe, interesting and anxiety-free optimal solution of new energy, and also opened the fast-forward mode of LINKE in the new energy market. At the Shanghai Auto Show, Lectra took Lectra EM-P super extended-range electric scheme as its new strength and Lectra 08 as its new carrier, which opened a new chapter in the brand’s strategy of accelerating the transformation of new energy in an all-round way.

As Lin Jie, general manager of Linke Automobile Sales Co., Ltd. said: "Linke is serious about growing up with users. We respect the personality of users, provide users with more new energy travel modes, and continuously change mobile travel to make people love travel more! "

Enjoy what you want, not just the car. In addition to the rich array of electrified products, Linke has prepared a highly immersive and trendy exhibition experience for the audience of Shanghai Auto Show, leading the way with young users. At the Lectra booth, you can not only intuitively understand the technical advantages of Lectra’s intelligent electric hybrid multi-scene through the VR equipment in the Co:VR experience area, but also experience the powerful control brought by the Lectra race genes in the WTCR racing simulation area. I look forward to more friends punching in at the Lectra booth in the 6.1H Hall, ordering a Lectra 08 special drink, and personally feeling the new energy products brought by the Lectra brand with "electricity" and the new trend charm of "not just cars"!

The CX6672 graph data transmission module empowers the data link of the new generation UAV.

UAV data link is an important part of UAV system, and it is the link between aircraft and ground system. UAV data link can be divided into uplink and downlink according to transmission direction. Uplink mainly completes the sending and receiving of remote control instructions from ground station to UAV, while downlink mainly completes the sending and receiving of telemetry data (flight control) and video images (image transmission) from UAV to ground station, and uses uplink and downlink for ranging according to the transmission of positioning information. The performance of data link directly affects the performance of UAV. According to the time and function, the UAV data link is divided into three stages:

The first stage: data transmission, which is mainly used for data transmission between flight control and ground stations. The main purpose is to adjust parameters, telemetry data and remote monitoring. Moreover, parameters can be adjusted during flight and flight data of flight control can be transmitted back, but large-capacity data cannot be transmitted.

The second stage: image transmission, which is used to meet the needs of high-resolution image/video real-time transmission for aerial photography, maintenance, measurement, mapping and monitoring. The UAV needs to be equipped with a wireless communication module that can realize wireless image transmission. At this stage, the image transmission mainly adopts two technologies: WiFi image transmission and COFDM radio image transmission. WiFi image transmission has the characteristics of low cost and small size, and it is quickly popularized in consumer drones. However, WiFi technology is designed for indoor static close range, and its transmission distance is only a few hundred meters, so it cannot be transmitted over a long distance. And the mechanism of WiFi carrier sense determines that it cannot be used reliably in multi-unit networks. COFDM radio station follows DVB broadcasting technology, which has high spectrum efficiency and long transmission distance, and can be applied to industrial UAVs with long-distance transmission. However, COFDM radio station generally adopts one-way broadcast transmission, which can not be used in networking, and the cost is very high. At present, it is gradually replaced by LTE image transmission with networking capability.

The third stage: digital and graphic transmission, multi-unit network. Traditional data transmission and image transmission all adopt independent modules, which occupy a large volume and consume a large amount of power. The new data link graph integrates data transmission, wide and narrow bands share wireless links, and the uplink and downlink are transmitted in both directions, which improves the efficiency of spectrum use. Single module supports serial port, network port, USB, HDMI and other interfaces; Serial port is used for data transmission, and network port, USB port and HDMI port are used for image transmission. With the rapid popularization of power line inspection, highway inspection, border inspection, surveying and mapping, fire prevention and other industries, the single-control single-machine mode can no longer meet the requirements. On the basis of two-way networking, multi-machine and multi-station networking is required.

Based on the application requirements of the above UAV scenes, Chenxin Technology launched the CX6672 graph data transmission module. Based on the SDR chip platform of Chenxin Technology, this module supports broadband data transmission of point-to-point and point-to-multipoint star networking. This module is based on LTE wireless communication standard and adopts.OFDM(orthogonal frequency division multiplexing) andMIMO(Multi-Input & Multi-Output,) and so on.technologyDifferent modulation and coding methods can be applied to adapt to different channel changes and obtain the maximum transmission efficiency.

Typical application scheme: high-speed functional automatic inspection system

A number of ground base stations are deployed along the expressway, and each ground base station is connected with the monitoring center through optical fibers. When the UAV patrols along the expressway and reaches the wireless coverage area of a base station, the patrol video image is transmitted back to the command center through the base station; When the UAV flies to the coverage area of other base stations, it automatically switches transmission paths seamlessly, and data is not lost during the switching process.
