轨道交通无线网络通信中的可靠性评估系统改进设计
Design improvement of reliability evaluation system for wireless network communication in rail transit
摘要
Abstract
As the traditional communication network reliability evaluation system for rail transit cannot balance the hard⁃ware performance,often loses the data produced in the operation of rail transit,and its assessment accuracy is low,the reliabili⁃ty evaluation system for wireless network communication in rail transit is improved. The system consists of sensor module,Zig⁃Bee technology module,gateway module and computer. The sensor module is used to collect operation node data of communica⁃tion network system for rail transit,and send the data to the ZigBee technology module for data processing. The router in ZigBee technology module is used to collect data. The data in the routers is resolved by ZigBee network coordinator. Based on this,the continuous working system is build,and the data in the system is sent to the gateway module. The data processed by ZigBee technology module is converted by the gateway module into the serial data easy to parse according to the level change. The proto⁃col update for the processed data is conducted with the general packet radio service,and then is transmitted to the computer for the reliability evaluation and analysis. The flow chart and key code for assessment of the rail transit wireless network communica⁃tion reliability are designed in the evaluation software. The experimental result shows that the designed reliability evaluation sys⁃tem has high evaluation accuracy.关键词
