摘要
通过对无线通信技术的比较,最终选用Wi Fi作为车地通信的无线通信技术,成功解决了CBTC仿真实验室车地通信问题。在设计过程中,首先对网络无缝漫游、网络配置、抗干扰处理进行研究,然后设计车载控制系统并多次改进。最终的车载控制系统经过较长时间运行,数据传输的实时性和完整性满足CBTC仿真实验要求,验证了方案的正确性。车地通信方案的解决,使CBTC功能能够在沙盘上准确仿真实现,为科研、教学、培训提供服务。
WiFi is chosen ultimately as a wireless communication technology of train-ground communication in order to solve the problem of the train-ground communication of CBTC by comparison of wireless communications technologies. In the process of design,network seamless roaming, network configuration, anti-interference treatment are researched firstly,then the vehicle control system is designed and improved many times. Finally,after running for a long time,correctness of the scheme of vehicle control system is verified,the requirements of CBTC simulation experiments are satisfied by the timeliness and completeness of data transmission. The solved scheme of train-ground communication can implement simulation of the CBTC function accurately on a sand table,it provides services for scientific research,teaching and training.
