摘要
京津城际C-3D型列控车载设备(ATP)故障集中在应答器传输通道关闭,故障原因是应答器系统的旁瓣干扰。通过对旁瓣干扰的分析和实际运营试验,调整应答器信息接收天线(BTM天线)距地面应答器的高度,解决应答器系统旁瓣干扰问题。
Most failures of the ATP system for Beijing - Tianjin Line occur to balise transmission channel being closed. The cause of the malfunctions is due to side lobe interference from the balise . In this paper, the side lobe interference is addressed by adjusting the distance between the BTM antenna of the balise and the wayside balise through analyzing the interference and conducting test in actual operation .
