China's standard emu, which was spearheaded by the China railway corporation, was named the "Renaissance" in China yesterday. Today, the "Renaissance" will start in the beijing-shanghai high-speed railway, taking G123 and G124 high-speed trains, respectively.

The number of moving cars is integrated with speed and manufacturer information

"Renaissance" is our country with completely independent intellectual property rights of China standard the emu, its successful development and production, and marked the railway complete sets of technical equipment especially in high speed emu has been one of the leading enterprises in the advanced world." Lu dongfu, general manager of China railway corporation, said in a naming ceremony that the name of China's standard motor vehicle group was named "revival", which represents the strong determination of the Chinese railway in the new era.

According to the introduction, the well-known Chinese Railway high-speed naming sequence will be phased out of the history stage.

At present, there are two types of "CR400AF" and "CR400BF". Among them, CR400AF is named as CR400AF, and CR400BF is named as CR400AF.

China railway corporation new emu compiled in accordance with the rules, new democracy emu adopt "CR" at the beginning of the model, "CR" is the abbreviation of China railway corporation, is refers to cover China standard with different levels of speed emu seriation product platform. The "400" in the model is the speed grade code, which means that the test speed of this type of motor vehicle can reach speeds of up to 400 kilometers per hour and above, and it can be sustained at 350 kilometers per hour. "A" and "B" for enterprise identification code, representing manufacturers; "F" is the technical type code, which stands for the power distributed electromoche group, and the other "J" stands for power concentrated power unit. "N" stands for the power concentrated internal combustion train group.

The unified standard of moving cars can be connected to the operation

Why to develop China's independent intellectual property rights? Wang yueming, lead researcher at the China academy of railway sciences, said that the "standard" of China's standard trains means that all high-speed trains will be able to connect and operate in the future. As long as the same speed class car, no matter which factory produces, no matter which platform produces, can connect to operate, the car of different speed grade also can rescue each other.

Wang Yueming introduction, China's high-speed rail based on importing, absorbing and digesting the again "innovation" of the birth of, originally from Europe, Japan has introduced the car type 1, type 2, 3 and 5 car four different technology platform, these vehicles technology path is different, although the destinations and combined with the technical characteristics of our country, but not after all we are completely independent of the products.

Wang yue said, these technology platforms do not have a unified standard system, do not type standardization system, not only the driver's work station is not the same, even the seat for the carriage capacity is different, cannot replace each other. Once a car breaks down, it is necessary to organize a passenger transfer, and the temporary car is likely to either "fail to hang" or "lack of seats".

Not only trains have this kind of embarrassed because models do not have a unified standard, each car needs to have a spare car at the station the emergency, moving car repair shop to complete all the components for the 4 kinds of car, high-speed drivers to all sorts of models are learning again.

The "China" of China's standard motor vehicle group means that high-speed rail has evolved from the earliest "hybrid" to "pure China" from the inside out.

China standard mobile will produce a series of products

It is understood that the "revival" will start at the Beijing south railway station and Shanghai hongqiao station on both ends of the beijing-shanghai high-speed railway, taking the G123 and G124 high-speed trains respectively.

Next, railway corporation will, according to the need of transportation arrangement "Renaissance" Chinese standard emu series product design and manufacturing to organize production, expanding the application of high-speed on the road in different speed level.

At present, has launched 350 kilometers per hour speed level 16 marshalling China standard the emu, level Chinese standard 250 km/h emu, 160 km/h speed level Zhang Gaotie intelligent power concentrated power emu and Beijing train r&d work.

In the future, China railway corporation will gradually develop CR300 and CR200 series of China standard emu according to the transportation market demand.

Liu Dongfu said, "Renaissance" CR400 series emu successfully developed and put into use, for our country comprehensive system master high iron core technology, accelerate the high iron "going out" has important strategic significance. China will take "Renaissance" China standard the emu as a platform, according to the actual needs of other countries in the world, to mold, design with the international competitiveness of the emu complete sets of technology and products, actively expand the international market, to promote China's high iron "go out".

S to watch

1 "longevity" longer

China's standard emu has made innovations in reducing the cost of full life cycle and improving safety redundancy. In order to adapt to China's vast area, temperature across the plus or minus 40 ℃, long distance, high strength, such as operation requirements, "Renaissance" for a 600000 km run, more than European standard 200000 kilometers. In the end, the vehicle performance index has been greatly improved, and the design life of the "Renaissance" has reached 30 years, while the harmony number is 20 years.

2 "body" is better

The train looks more elegant and more energy efficient, using a new low resistance streamlined locomotive and body smoothing design. Friends who have been in harmony will find that there is a "bulge" on the roof of the emu, which is actually powered by an electric bow and air conditioning system. "Renaissance" under the "bulge" sinking to the roof of air duct system, make train not only looks more beautiful, train resistance than both choice series by 7.5% - 12.3%, the train runs at 350 km per hour, hundreds of kilometers per capita energy consumption by 17% or thereabouts.

3 "capacity" is bigger

From the outside, it's better to look at the "Renaissance" figure, and after boarding the car, travelers will be amazed at the larger space, since the train height has increased from 3,700 millimeters to 4050 millimeters. While under the condition of cross section, space increases, according to the test run 350 kilometers per hour, the train operation resistance, hundreds of kilometers per capita energy consumption and the interior noise decreased obviously, and intentional passengers will found that seat space is more capacious.

4 comfort is even higher

The air conditioning system of the "Renaissance" is fully considering the influence of the external pressure wave of the car, which can reduce the discomfort of the ear during the tunnel or the intersection. The train has a variety of lighting control modes, which can provide different lighting conditions according to the passenger demand. Of course, it's worth the fact that the car has full WiFi coverage. Of course, how the connection will work remains to be seen by the passengers.

5 "vigilance" is higher

"Renaissance" set intelligent perception system, establish a strong security monitoring system, the whole car deployed more than 2500 posts, most monitoring models are more than ever before about 500, to be able to walk line state, bearing temperature, the temperature of the cooling system, brake system status, classroom environment for all-round real-time monitoring and gathering all kinds of vehicle state information of more than 1500 items, to provide comprehensive, multidimensional fault diagnosis and maintenance support. When the train is abnormal, it can automatically alarm or warn, and automatically take the speed limit or stop measures according to the security policy. In the connection of the head and carriage of the car, a collision suction device is added, which can be used to improve the passive protection ability of the motor vehicle in the case of accidental collision in the low-speed operation.
