摘要
根据大秦线重载列车Locotrol技术的要求,采用800M电台作为通讯手段之一,用于主控机车和从控机车之间进行必要的通信和实时传递控制命令。在山区隧道群区段由于隧道效应以及会车等因素对电波传播衰耗造成的影响,造成主控机车和从控机车之间无法建立通讯。研究的弱场补强方案是在射频中继放大的基础上,结合信道选择、切换保护、收发转换等功能,将射频信号放大并进行相应的传输,通过配套的电缆和天线来保证弱场区段内Locotrol系统通讯的可靠性,从而保证重载列车运行的安全。
To ensure locotrol technology performance on the Da-qin Line, the locomotives used 800 M radio to transmission the necessary communication and control signal.But when the locomotives traveled at monuntainous and tunnel area, because the environment reason, may caused the lead locomotive couldn＇t establish communication with the remote locomotive. It would bring potential danger to train safety. It was studied the Wayside Compensation System （WCS）, mounting at the weak signal area to re-transmitted message signal and improvement signal strength. Through the fieldwork test, the wayside compensation equipment could meet Locotrol System requirement completely and ensure running safely of heavy haul.
