The invention discloses a train control wireless communication system and method using a PIS channel as redundancy, the system comprises an LTE train-ground wireless transmission system and a PIS train-ground wireless transmission system, a trackside operation control system and a train-mounted operation control system carry out real-time data interaction through the LTE wireless channel and the PIS wireless channel, and data transmission can adopt a first-arrival first-use processing logic. And a processing mode of checking and verifying multi-path data can also be adopted. The technical characteristics and the wireless frequency point resources adopted by the wireless communication of the PIS system are different from those of the existing LTE technical system, so that the same frequency interference probability of the whole system is reduced; meanwhile, the redundancy of a train-ground wireless communication channel is increased, the overall stability and reliability of a wireless system are improved, and the line operation service level is improved.

    本发明公开了一种利用PIS通道作为冗余的列控无线通信系统及方法,该系统包括LTE车地无线传输系统和PIS车地无线传输系统,轨旁运控系统和车载运控系统通过LTE和PIS两个无线通道进行数据的实时交互,传输数据可采用先到先用得处理逻辑,也可以采用多路数据校核验证的处理方式。由于PIS系统的无线通信采用的技术特性和无线频点资源均与既有得LTE技术制式不同,因此降低整体系统的同频干扰概率;与此同时增加了车地无线通信通道的冗余度,提高了无线系统的整体稳定性和可靠性,提升了线路运营服务水平。
