深圳地铁乘客资讯系统场段信号覆盖优化

Shenzhen Metro Passenger Information System Field Signal Coverage Optimization

车地无线网络的稳定运行是乘客资讯系统能否实时提供各类信息的重要保障,结合乘客资讯系统的特点,从乘客资讯系统无线信号组网入手,针对现场信号连接能力较弱的问题探讨场段信号优化的合理方案。通过对场段信号覆盖信道的规划和选择逻辑的调整,实现车地无线网络的优化,从而方便乘客资讯维护工作人员远程查看车辆运行信息。

The stable operation of the ground wireless network is an important guarantee for the passenger information system to provide all kinds of information in real time.Combining with the characteristics of passenger information system,starting with the wireless signal networking of passenger information system,this paper discusses the reasonable scheme of field segment signal optimization aiming at the weak field signal connection ability.Through the planning of the signal coverage channel of the field segment and the adjustment of the selection logic,the optimization of the wireless network between the vehicle and the ground is realized,thus facilitating the passenger information maintenance staff to remotely view the vehicle operation information.
