Domestic rail transit network control chip come out

Recently, the first domestic rail transit control chip was embedded in the network control system at the laboratory of Dalian Electric Holding Company in Dalian.With the closing of the departure switch, more than 2 million control commands passed through the chip with only fingernail size, Drive high-speed train ride.

'The first domestic rail transit network control chip compatible with all the functions of foreign chips, ranging from minus 40 degrees Celsius to 85 degrees Celsius, electromagnetic compatibility can meet a number of indicators, such as electrical fast transient burst, lightning, Surge, RF radiation, etc. 'In the car Dalian Electric Power Research and Development Center, said Wang Feng, deputy director, with similar foreign products, the same domestic chip in accordance with the IEC61375 series of international standards designed by the German Bombardier and Siemens compliance Test. Train network control system is equivalent to the vehicle's brain, all the vehicle control commands, the status of each execution need to be transmitted and controlled through the network system and monitoring. 'And the chip is the network hub, no chips, 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.

'Train network control chip is a dedicated chip for rail transit, both to meet the real-time data transmission, but also in the train on the harsh temperature, electromagnetic compatibility and other environments work properly, technical difficulty.' Wang Feng told reporters , EMC design and temperature resistance is not good, can cause chip crashes and confusion and other failures.

Chip is the heart of electronic information products, representing the commanding height of scientific and technological revolution and industrial change.Highly-acclaimed as China's business card has laid a solid foundation for China's high-speed rail take-off.China has formed a complete and advanced high-speed railway Technology system, the high-speed EMU technology represented by China's standard EMU, as well as various technical fields of engineering construction, train control, traction power supply, operation and management, risk prevention and control, system integration, etc., all reached world advanced level, especially in China The standard EMU 'Renaissance' has become the current high-speed railway equipment leader with its excellent aerodynamic performance, smart sensing performance and economic comfort.
