In order to comprehensively improve the design, software development and manufacturing technology level of China's high-speed railway EMUs, we will create a high-speed EMU design and manufacturing platform suitable for China's national conditions and road conditions, realize the autonomy, standardization and serialization of China's high-speed railway EMUs, and promote the EMUs. From the perspective of China's manufacturing to China's creation, since 2012, under the leadership of China Railway Corporation, China Railway Science Research Institute has taken the lead in bringing together the strength of China Car Group and related companies to carry out the design and development of China's standard EMUs.
The “Revival” China Standard EMU has built a technical standard system with complete system, reasonable structure and advanced science. The basics of EMU, car body, running gear, cab layout and equipment, traction electric, braking and air supply, train More than 10 aspects of network standards, application and maintenance have reached the international advanced level. The “Revival” China Standard EMUs use a large number of technical standards such as China's national standards, industry standards, and corporate standards of China Railway Corporation. At the same time, they adopt a number of international standards and foreign advanced standards, and have good compatibility with 254 important standards. China's standards account for 84%. The most important thing is that the overall design of China's standard EMUs and key technologies such as car body, bogie, traction, braking and network are independently developed by China and have completely independent intellectual property rights.
On June 25, 2017, the China Standard EMU was officially named “Revival” and officially launched in Beijing and Shanghai on the 26th. Starting from August 21, 2017, the Beijing-Tianjin-Hebei region will operate 22.5 pairs of “Revival” EMU trains. On September 21, 2017, the railway will implement a new train operation map, and additional passenger and freight trains will be added to some lines. The “Revival” EMU took the lead in achieving a speed of 350 km/h in Beijing-Shanghai high-speed rail. China has once again become the country with the highest speed of high-speed rail business operations in the world.

The ride experience is better, not only charging but also WiFi. The “Revival” China Standard EMU has fully covered the WiFi network and set up 220V power outlets for uninterrupted passengers. The air conditioning system fully considers the effect of reducing the pressure wave outside the vehicle, reducing ear discomfort through tunnels or rendezvous. Sense; the train has a variety of lighting control modes to provide different lighting conditions according to passenger needs. The “Revival” China Standard EMU has also adopted a variety of vibration and noise reduction measures, improved washing facilities, and barrier-free facilities, which can provide passengers with a better ride experience.

The “Revival” China Standard EMU has an intelligent sensing system and a powerful safety monitoring system. More than 2,500 monitoring points are deployed throughout the vehicle, which can be used for the state of the running, bearing temperature, cooling system temperature, and braking system. State and guest room environment for comprehensive real-time monitoring. The “Revival” China Standard EMU also added a collision energy absorbing device to improve the passive protection capability of the EMU. In order to adapt to the needs of China's vast territory, complex environment (-40 ~ +40 °C), long-distance, high-intensity operation, the "Revival" China Standard EMUs are assessed according to the highest level (design life 30 years or 15 million kilometers) The main structural components, the vehicle is used for 600,000 km application assessment (typically 400,000 km in Europe).

The sensing system is more intelligent, with abnormal automatic speed limit or parking. The “Revival” China Standard EMUs collect more than 1,500 vehicle status information, comprehensively monitor the train operation status, and sense the train status in real time, including safety performance, environmental information (such as temperature), and record the operation of each component. To provide support for comprehensive, multi-dimensional fault diagnosis and maintenance. When the train is abnormal, it can automatically alarm or alert, and can automatically take speed limit or parking measures according to the security policy. In addition, the “Revival” China Standard EMU also uses remote data transmission to obtain vehicle status information in real time on the ground, improving ground synchronization monitoring and remote maintenance capabilities.

The low-resistance and streamlined design of the car body not only greatly reduces the energy consumption, but also significantly reduces the noise inside the car. The "Revival" China Standard EMU train resistance is reduced by 7.5%-12.3% compared with the existing CRH380 series, and the energy consumption per 100 km of the 350km/h speed grade is reduced by about 17%, effectively reducing the energy consumption for continuous operation. In the case of an increase in the section of the car body and an increase in space, when the "Revival" China Standard EMU was operated at a speed of 350 km/h, the train running resistance, per capita energy consumption per 100 km and noise inside the vehicle decreased significantly, showing good energy saving. Environmental performance.
