What problem is BYD's huge investment in cloud track technology used to solve?

"Cloud Track" is a solution to the global urban congestion problem, and it is expected to become a new type of convenient transportation in the future. This also shows that BYD will officially enter the fourth largest industry after IT, automobiles and new energy-light rail. So what is so special about this "cloud track"?

After five years of research and development, the "cloud track" has long been premeditated.

With the deepening of urbanization in China, subways have been built in big cities, and traffic congestion in small and medium-sized cities has become increasingly serious. However, some places do not have the strength to invest heavily in the subway. At the same time, the cost of the subway is too high, so the construction of the subway must be approved by the National Development and Reform Commission, and meet the hard conditions such as the general budget revenue of local finance is above 654.38+000 billion yuan, the gross domestic product is above 654.38+000 billion yuan, the urban population is above 3 million, and the passenger flow scale of the planned line is above 30,000 in one-way peak hours. BYD's straddle-type rail transit, on the other hand, avoids the above requirements and does not occupy the land index. Local governments can start construction on their own without the approval of the National Development and Reform Commission.

BYD began to study the topic of "Electrification of Public Transport" from 20 1 1. It believes that if buses and taxis in cities can be replaced by electric vehicles, the emissions of cities will be reduced by at least 30%. After more than five years of planning by BYD Academia Sinica, * * * invested thousands of people with a capital of 5 billion. This year, BYD officially established the Light Rail Transit Research Institute (ministerial level), which has five departments and one center, specializing in the research and development of "cloud track".

In addition to the world premiere in Shenzhen, BYD also laid out other "cloud track" projects. According to a report by Zhejiang Fenghua News Network on May 27th this year, BYD will establish the first straddle-type monorail production base in Fenghua after the new energy vehicle base project is signed and settled in Fenghua, if future conditions permit. At the same time, in June this year, BYD has reached an Airbus project planning and construction cooperation with Shenzhen Pingshan New District to build a straddle-type monorail train with a total planned route mileage of not less than 50 kilometers, and strive to build a national Airbus demonstration zone within three years.

At the world launch ceremony, Wang Chuanfu, chairman and president of BYD, revealed that Shantou has signed an agreement with BYD to lay a 250-kilometer "cloud track". This is also the first city to sign an agreement with BYD. At present, about 20 cities have reached a preliminary agreement with BYD, and more cities will see the "cloud track" in the future. Earlier, China Development Bank and BYD formally signed a strategic cooperation agreement. 20 16 to 2020, the total amount of cooperative financing between the two parties is planned to be 60 billion yuan.

Finally, building products into "XX series" has always been a common method of BYD brand promotion, and it is not surprising that "Cloud Track" project is packaged as a new brand promotion. In this regard, the car headline APP specifically asked the relevant person of BYD brand public relations department for verification, but the other party did not give a clear answer.

What is the difference between "cloud track" and general light rail?

Many cities have been plagued by road congestion for a long time, and developing rail transit has become the only solution at present. At this time, the choices of some cities generally include ground trams (Changchun), elevated double-track subways (Chongqing) and elevated monorail subways (BYD).

On the whole, trams are usually laid on the ground and enjoy the exclusive right of way, but the traffic volume is relatively small, which is not suitable as the main line of rail transit in the current urban development. The most obvious problem of elevated double-track subway is that it is not suitable for the construction of central cities. It is often used as an underground subway to extend to the suburbs, and it is changed from underground laying to overhead laying to reduce costs. One advantage of monorail subway is that it adopts rubber-tyred structure, which has no noise pollution and can enter the central city. Another advantage is that the track beam is simple in structure, which has less shielding to the urban landscape, and it also makes it possible for the monorail subway to shuttle between high-rise buildings in the city center.

According to BYD's plan, the power supply will be changed from the traditional monorail beam to the vehicle battery, and the track structure will be further simplified. The track itself does not need to lay catenary/three-track system, and the communication signal system does not need track circuit after adopting the mobile blocking system based on wireless communication technology, so the track system can be simplified into pure reinforced concrete components, further reducing the cost and making it affordable for more cities.

In addition, the cost of "cloud track" is only 1/5 of that of ordinary subway, and the construction period is 1/3 of that of subway. While enjoying independent road rights, it can also adapt well to the urban ecological environment. In order to reduce the weight of the car body, the "cloud rail" is made of aluminum alloy, which can effectively deal with the slight distortion caused by the car body during operation. After adopting the mobile block system based on wireless communication technology, the communication signal system no longer needs track circuit, which can further reduce the cost and make it affordable for more local cities. At the same time, the train adopts unmanned operation mode and is equipped with BYD's unique train control technology. In the case of power failure, the energy storage battery can also ensure that the train runs for 3 kilometers to reach the station. The maximum speed of vehicles can reach 80km/h, the average speed is 30-45kn/h, and the carrying capacity is1-30,000 people/hour (one way), which is equivalent to a small subway, and can further solve the "last mile" problem of public travel.

At present, BYD's "cloud track" has two types: A and C, of which Line A is used for connecting stations of special lines such as airports, railway stations and subways. It is characterized by a large traffic volume and a large number of people. It can connect satellite cities and surrounding cities, as well as hospitals, schools, scenic spots, shopping malls and residential areas. Line C is used to go deep into the community, close to houses, shopping malls, hospitals, schools, office areas, CBD, bus stations, subway stations and so on. , characterized by strong ornamental, the station can go deep into the building. From this point of view, unlike ordinary subway light rail, BYD has come up with a set of solutions to the "last mile" problem of mass travel, and the "cloud track" is really powerful.
