　　According to the data, there are about 67,000 taxis in Beijing at present, including 5,000 electric taxis. With the encouragement of the policy of "scrapping at maturity, purchasing with vehicle incentive indicators and updating other vehicles approved by the government", it is estimated that the scale of replacing taxis with electric vehicles will be about 10,000 each year. According to the Notice on Financial Incentive Policy for Updating Taxi to Pure Electric Vehicle issued by Beijing (hereinafter referred to as the Notice), the replaced vehicles are "compatible with charging and replacing batteries" in principle, and the addition of 10,000 electric taxis every year will bring great challenges to the existing power station network.

　　How many power stations are there in the whole city? Can the total amount of batteries that can be replaced meet the needs of taxis? After visiting a number of power exchange stations in Beijing, the reporter found that the preparation work to meet the demand for new electric taxis has begun, the power exchange enterprises are actively deploying more outlets, and the recruitment of personnel is also in the process of promotion.

　　■ The power exchange station is preparing for capacity expansion.

　　According to public information, up to now, BAIC New Energy has put in more than 12,000 electric taxis nationwide, and built a total of 140 power stations. Specific to Beijing, the number of power stations displayed on the official website of BAIC New Energy is 59, but during the actual visit, it was found that the locations of some power stations marked on the map of official website were not accurate. The staff of the power station told the reporter that if you want to inquire about the power station in the city, you can download an App called "Aodong Power Bar", which not only marks the exact location of the power station, but also shows the remaining battery quantity and queuing situation. On the software, the models currently supported for inquiry are BAIC EU220, EU260 and EU300. According to the requirements of the Notice, "the driving range of vehicles should not be less than 300 kilometers in principle", so after selecting the model of EU300, the total number of power exchange stations displayed is 31. If each power station is filled with 28 batteries, the number of full-load operations in one day is 288 (recycling). In addition, due to the fact that most of the replaced batteries have more residual electricity in actual calculation, the charging time is shortened. Therefore, the number of full-load operations in each power station can be counted as 300. In other words, at present, Beijing can provide EU300 with 9300 power exchanges. A taxi needs to change electricity twice a day, so the current power station can only serve 4650 electric taxis. If all the 10,000 electric taxis added this year adopt the power exchange mode, the number of power exchange stations is obviously insufficient.

　　However, the staff of the power station told reporters that the new power station is in the process of active layout, and it is expected to be officially opened in the near future once there is demand. According to a staff member of a power station in Chaoyang District, Beijing, "According to the actual situation, a power station only needs one staff member, but our station now has three or four employees, just to prepare for the upcoming expansion." Another staff member of a power station in Changping District also revealed the same information: "In the case of meeting the current operating needs of the power station, personnel are still being recruited."

　　■ Business model becomes the biggest problem.

　　"The power exchange is still in a special stage of development. Perhaps the power exchange station at this stage can’t meet the power exchange needs of a large number of taxis, but it has a process of development and construction." In an interview with the reporter of China Automotive News, Xu Haidong, assistant secretary general of China Automobile Industry Association, was not very worried about the battery supply of the power station. He said that with the increase of the number of electric taxis, the number of power stations will also increase, and the layout is expected to be gradually improved. The most noteworthy issue is how to find a mature business model and solve the profit problem of power stations.

　　According to Qin Si, deputy general manager of Beijing Aodong New Energy Investment Co., Ltd., the current power station change mainly relies on electricity charges for profit. On the premise that the power station uses a lot of electricity, it costs 0.8 yuan to use 1 kilowatt hour. According to the calculation of 5 kilometers driven by 1 kilowatt hour, the electricity fee is 0.16 yuan per kilometer, while the service fee is 0.35 yuan per kilometer driven by electric taxis. That is to say, every kilometer driven by electric taxis, the power station gains 0.19 yuan. If the mileage of each electric taxi reaches 200 kilometers each time, the gross profit of changing electricity for each electric taxi is 38 yuan.

　　Qin Si pointed out that the key to the profitability of power stations is the load rate. Under normal circumstances, to achieve profitability, the load rate needs to reach more than 65%. At present, the average load rate of power stations in Beijing is only 20% ~ 25%.

　　During the visit, the reporter also found that at present, power stations are generally "not enough to eat". In Qiushi Street, Chaoyang District, the reporter talked with the staff for about 40 minutes, during which no electric car came to exchange electricity. According to the staff, the current number of battery changes per day is only single digits, but according to him, in busy sites such as Bawangfen Station in Chaoyang District, the number of battery changes per day can exceed 20 times. However, according to Tan Si’s calculation, in order to achieve the 65% load rate required for profit, each power station needs to serve about 195 electric vehicles every day.

　　It is conceivable that once 10,000 electric taxis are added in Beijing this year, the problem of profitability is expected to be solved, but before the official operation, the power station operators need huge upfront capital investment. It is reported that at present, the equipment and construction cost of each power station is about 3 million yuan (excluding land costs), and it takes about 2 million yuan to buy spare batteries. According to the idea of Aodong New Energy, if the average service radius of the urban area is 2.78km, 100 power exchange stations will be built in Beijing, and the initial investment cost will need at least 500 million yuan.

　　"At present, the business model of the power exchange technology route is still immature. The comprehensive electrification of taxis in Beijing is just a useful exploration and practice. I hope that by trying first, it can provide new ideas for the development of the automobile industry." Xu Haidong said. Our reporter Shi Yunyun

China Auto News (2019-07-29 008 Edition)

　　Cctv news(Focus interview): "For a big country with a population of more than 1.4 billion, the basic position of agriculture cannot be ignored or weakened at any time. It is true at any time to have food in hand and not panic in mind." The Great Northern Wilderness is one of the three black soil belts in the world. The fertile soil and abundant precipitation here are very suitable for agricultural development, and there is a saying that "the black soil will sprout when you pinch it, and the chopsticks will sprout". After decades of efforts, the Great Northern Wilderness has already become a great northern warehouse, which has played a great role in solving the problem of food and clothing for China people. In September 2018, General Secretary of the Supreme Leader came to Jiansanjiang Branch of Beidahuang Group for investigation and investigation, which put forward new requirements for grain production here and brought more vitality and development opportunities here.

　　In May, rice fields in Sanjiang Plain were busy transplanting rice seedlings, and so was Hongwei Farm of Beidahuang Group. However, in this field, only machinery is busy, and no one can be seen. Now, Beidahuang Group has taken the lead in opening a "new era of unmanned operation" of modern agriculture in China.

　　So how do these machines work? In fact, the people who command them are miles away.

　　The Smart Farm Command Center is equivalent to the brain nerve center system of the unmanned farm. When the workers operate here, they can command all the unmanned machines in the farm to farm. For example, which machine to start and what route to take, including a few centimeters and millimeters of line margins, can be set very accurately.

　　Set up all the data, give the start instruction, and the designated machinery on the farm will start working.

　　Precision transplanting and fertilization, which used to be impossible for several days, are now finished in half a day. Although people are not in the field, these machines are very obedient, because the remote operating system of the command center can monitor the whole process of mechanical operation in real time and control every step accurately.

　　And these machines don’t just passively accept instructions, they can interact intelligently with commanders.

　　These scenes that look like science fiction movies have now become a reality here. In recent years, Beidahuang Group has intensified its scientific and technological innovation, and used advanced technologies such as Beidou satellite navigation and 5G to take the lead in exploring the construction of unmanned smart farms. Six demonstration areas have been built, with an operating area of over 10,000 mu, and the whole process of agricultural planting can be unmanned.

　　Injecting agriculture into the power of science and technology will inevitably develop rapidly. In recent years, the grain production of Beidahuang Group has not only greatly increased production and increased efficiency, but also significantly improved the quality of grain, creating a number of high-quality agricultural products brands — — This is also the idea and direction advocated by the state to develop grain production.

　　There are many self-produced high-quality agricultural products in the lobby of Beidahuang Agricultural Machinery Center. When the General Secretary of the Supreme Leader visited in 2018, he paid special attention to these agricultural products.

　　Later, General Secretary of the Supreme Leader came to the paddy field outside with an area of 10,000 mu of land to learn about the production and living conditions of the farm workers who were farming, and said to them, "The Great Northern Wilderness has played a great role in solving the problem of food and clothing for China people. Now the development of mechanization, informationization and intelligence here is great, and it is not easy to build the Great Northern Wilderness."

　　The land guide was particularly touched by the general secretary’s words. Three generations of his family are farm workers. Grandpa was the first pioneer who came here in response to the call in the 1950s, and his father worked here all his life. It can be said that the youth of his whole family has been dedicated to this land.

　　In 1950s, China began to develop the Great Northern Wilderness on a large scale. Tens of thousands of builders responded to the call and came here to break ground and launched the feat of "asking for food from the wasteland". At that time, the Great Northern Wilderness was still full of thorns and swamps, and the conditions were extremely difficult. The pioneers suffered unimaginable difficulties.

　　Difficulties and hardships did not knock down the pioneers, but they had a sense of mission in their hearts.

　　After several generations of efforts, the Great Northern Wilderness has now become a solid northern warehouse. However, the sense of responsibility that people in the Great Northern Wilderness should work hard to grow grain and mostly produce grain for the country has been passed down from generation to generation. In 2018, the General Secretary of the Supreme Leader came here to inspect and encourage the people in the Great Northern Wilderness, which added confidence and motivation to the younger generation.

　　The new generation of builders are still farming, but their methods are completely different from those of their grandparents.

　　The land guide has been renting other people’s drones before, and recently the land guide plans to buy one. Although grandpa didn’t quite understand it, he still expressed his support. Now grandpa often laments that he has planted land all his life, but now he is a layman compared with these young people.

　　The modernization of agriculture in the Great Northern Wilderness is only a microcosm of China’s agricultural development. In recent years, with the vigorous promotion of the state, all major grain producing areas are gradually realizing the transformation from backward farming methods to large-scale mechanization and automation. Now, for many growers, farming has become a brand-new way of life.

　　Like Zhou Dehua, farmers in the Great Northern Wilderness Smart Farm now have a special fertilization proposal for each piece of land. According to this formula, the yield and quality of grain are much higher than before. Behind this change is still the power of technology.

　　Only when growers can understand and learn, can science and technology play its role. This requires not only vigorous scientific research, but also efforts from all parties to do the work according to the needs of growers, so that scientific research results can become a useful magic weapon for growing grain. For example, behind the fertilization formula, there are many efforts of researchers.

　　Researchers collect samples, conduct tests, form scientific data, and then transmit them to the big data platform of the farm Internet of Things.

　　Internet of Things big data platform is an important achievement of information construction of Beidahuang Group in recent years. At present, all kinds of intelligent equipment are installed in each plot in the demonstration area, which can monitor and collect all kinds of data in real time for 24 hours, and at the same time transmit them to the information platform for intelligent analysis, forming scientific guidance to guide growers to accurately operate every link of grain growing.

　　The new agriculture needs new thinking, and the spirit of struggle of the people in the Great Northern Wilderness will not change, but the pace of learning will keep moving forward.

　　"Agriculture is a basic industry, and China’s modernization cannot be separated from agricultural modernization." We can see that in the endless Sanjiang Plain, large-scale machinery criss-crossing fields, unmanned aerial vehicles fertilizing and spraying drugs, plus improved seed selection and scientific soil testing and fertilization have changed people’s traditional impression of grain production. Grain production is entering the era of scale, automation and intelligence. This also gives us a direction to ensure food security, that is, "to revitalize agriculture, we must plug in the wings of science and technology, and we must rely on excellent talents, advanced equipment and parks that are suitable for industrial development."

With the attention of the scientific and technological community, Voice Technology grandly demonstrated its latest masterpiece-Tecnophantom Ultimate 2 tri-folding screen intelligence today.
