Construction And Realization Of Bus Security Control System For Catenary Work Vehicle

With the railway by leaps and bounds, to carry out all types of railway maintenance projects catenary cable car operation to run operations more frequently, the operational safety is very important. Catenary the safe operation of vehicle operation control, production of railway safety has become one of the topics that urgently need solving. The current operations vehicle traffic safety equipment can not be fully realized catenary operation requires the safe operation of vehicles, it is necessary to conduct further studies to solve the problem.Based on the analysis of existing regulations and vehicle operating vehicle traffic safety equipment, starting a systematic analysis of the catenary operating vehicle traffic safety needs of the provisions of the regulations and had failed to take account of factors to take technical measures to protect the catenary operating vehicle driving safety. Seize the CAN bus in the data communication process outstanding reliability, real-time and flexibility, the CAN bus technology to the safety car catenary operation to the operating system, can greatly avoid the human factor in car traffic catenary operation, work safety hazards caused by the process, to ensure to complete electrical service work efficiently and securitily.This paper catenary working vehicle use and operation of the current situation analysis, based on CAN bus catenary operation control system for the safe operation of vehicles. For security point of view, the characteristics for the CAN bus, using the most important devices use high priority sites, plays an important device nodes with low priority, non-essential equipment, the node with the lowest priority programs. Combining the characteristics of CAN bus technology, design communications vehicle procedure and CAN node module.
