Recently, the first domestic rail transit control chip was embedded in the network control system in the CRRC Dalian Dian Company laboratory. With the closure of the starting switch, more than 2 million control commands were accurately transmitted through this nail-sized chip, driving high-speed trains to ride. "The first domestic rail transit network control chip is compatible with all the functions of existing foreign chips. From the temperature of -40 degrees Celsius to 85 degrees Celsius, electromagnetic compatibility can meet a number of indicators, such as electrical fast transient bursts, lightning strikes, Surge, radio frequency radiation, etc.†Wang Feng, deputy director of CRRC Dalian Electric Traction Research and Development Center, said that this domestically-made chip is also designed in accordance with the IEC 61375 series of international standards and passed the consistency between Bombardier and Siemens. test. The train network control system is equivalent to the brain of the vehicle. All vehicle control commands and status of each execution need to be transmitted and controlled and monitored through the network system. "The chip is the backbone of the network, there is no chip, the entire train network can not be established, the signal transmission and control between the various systems can not be normal communication and exchange." Wang Feng said. "The train network control chip is a special chip for rail transit. It must meet the real-time nature of data transmission, and it must work under harsh environments such as temperature and electromagnetic compatibility on the train. It is technically difficult." Wang Feng told reporters , electromagnetic compatibility design and poor temperature resistance, will cause the chip to crash and confusion and other failures. The chip is the “heart†of electronic information products and represents the commanding heights of the technological revolution and industrial transformation. The Chinese high-speed railway, which is known as the "Chinese name card," has laid a solid foundation for the take-off of China's high-speed rail. China has formed a complete advanced technology system for high-speed railways, high-speed EMUs represented by China's standard EMU, and various technical fields such as engineering construction, train control, traction power supply, operation management, risk prevention and control, and system integration. Reach the world advanced level. In particular, China's standard EMU "Fuxing" has become the leader in high-speed rail equipment with its excellent aerodynamic performance, smart sensing performance and economical comfort.
