摘要: 为解决既有采用WLAN方案地铁线路面临的无线干扰问题,提出基于PRP的车地通信冗余方案,引入不同制式的无线链路,使信号车地通信单网信息经由冗余通道传输,从而提高信号系统车地通信的可靠性。该方案进行实验室及地铁线路现场动车测试验证,对测试结果进行对比分析,并对信号系统中PRP方案的应用场景进行展望。

关键词: PRP, WLAN, LTE, 冗余通道

Abstract: In order to solve the problem of wireless interference faced by existing metro lines using WLAN scheme, this paper proposes a train-ground communication redundancy scheme based on PRP. Wireless links of different standards are introduced to make the single network information of signal train-ground communication  transmitted through redundant channels, so as to improve the reliability of train-ground communication in signal system. The scheme has been tested and verified in the laboratory and on-site on metro lines. In this paper, the test results are compared and analyzed, and the application scenario of PRP scheme in signal system is prospected.

Key words: PRP, WLAN, LTE, redundant channel
