针对传统的轨道交通通信系统在不同建设阶段,采用的通信标准不一致,导致轨道交通通信网络无法实现信息共享的问题,设计并实现了基于HTML5的嵌入式移动智能终端的轨道交通通信系统。设计的基于嵌入式终端的硬件设计包括嵌入式终端的硬件选择,转换电路的设计、通信接口的设计和以太网扩展模块的选择,设计的基于HTML技术的软件系统包括通信信号的接收程序和信号的收发程序。仿真结果表明,相对于传统的通信系统,利用基于HTML5的嵌入式智能通信系统能够实现不同建设阶段的通信系统的兼容,为城市轨道交通的安全运行提供了保障。
In view of the inconsistent communication standards of the traditional rail transit communication system in different stages of construction, the problem of information sharing can not be achieved in the rail transit communication network, and a rail transit communication system based on HTML5 embedded mobile intelligent terminal is designed and implemented. The design of hardware design based on embedded terminal includes the hardware selection of embedded terminal, the design of converter circuit, the design of communication interface and the selection of Ethernet extension module. The designed software system based on HTML technology includes the receiving procedure of communication signal and signal Send and receive programs. The simulation results show that compared with the traditional communication system, the embedded intelligent communication system based on HTML5 can realize the compatibility of the communication systems in different stages of construction, which ensures the safe operation of urban rail transit.
