无线重联通信弱场补强设备应用研究

无线重联通信系统的性能受电波传播环境影响较大,尤其在山区短隧道群区段,由于隧道、弯道地形、山体阻挡等因素影响,可能会造成主控机车和从控机车之间通信丢失甚至通信中断,进而影响组合列车的安全开行和平稳操控.为了尽可能减少无线通信弱场区段对无线重联系统的不利影响,采用无线通信弱场地面补强设备对弱场区的无线通信信号进行补偿传输,为重载组合列车安全开行和平稳操控提供保障.

Study of Applying Weak Field Reinforcement Equipment in Multi-traction Radio System

The performance of multi-traction radio communication system will be vulnerable greatly to the influences of radio propagation environment,especially in the short tunnel group of mountainous area.Due to the the limitations of geology and landform in tunnels,curve and mountain.the communication between the leading locomotive and the assisting locomotives may be lost or even be interrupted,which will affect the safe operation of the combined train.In order to minimize the disadvantageous effect of the weak field on the multi-traction radio communication system,a ground weak field reinforcement device for radio communication is used to compensate the transmission of radio communication signals in weak field areas,so as to provide a guarantee for the safe and smooth operation of heavy-haul combined train.
