Rail Transit Intellectualization
Synopsis
On-line train monitoring and early warning system can realize tandem access and processing of perception data and train control information such as sensor, infrared camera, video and radar, construct highly reliable backbone perceptual communication network, and support important functions like online monitoring and early warning of train operation state, synchronous data collection, integrated analysis processing and storage of onboard data, train positioning and obstacle detection. At the same time, the system stability and reliability meet requirements of train operation in severe environment and meet intelligent development trend of rail transit, taking the leading role in domestic industry. The first generation SN6500 has successfully conducted loading test and commissioning over CRH380AL, CRH380BL and CRH380CL, passed loop test acceptance and has completed 300,000 km main track operational test on CRH380C-6301L of Beijing-Shanghai Line from December 2012 to May 2013, winning general consent from the Ministry of Science and Technology, China Railway Corporation and various main engine plants. The second generation of miniature system with higher integration and stronger access and integrated processing capacity has been launched. It will undergo installation test and online pilot run on the next generation of metro train of CRRC Sifang Co., Ltd. . Hopefully it will become the new benchmarking product in intelligent rail transit field.
