CIR设备安装于高铁动车组司机室,用于运行中列车和前方临站、调度所之间的通信联控,是保证动车组行车安全的重要设备。CIR设备中送受话器使用频率最高,应用中发生故障较高,所以根据现实要求,从送受话器着手,加强设备维护维修,压缩故障延时,确保行车安全。1选择课题1.1小组概况上海枢纽车间CIR设备QC攻关小组概况见表1。本次活动以紧凑型送受话器改造为出发点,通过开展QC攻关,降 The CIR equipment is installed in the driver’s cab of the high-speed rail EMU for the communication and control between the train in operation and the temporary stop in front of the dispatching station. It is an important equipment for ensuring the driving safety of the EMU. In the CIR device, the highest frequency of the receiver is used and the fault occurs in the application. Therefore, according to actual requirements, the receiver should be started to enhance equipment maintenance and repair, compress the delay of the fault, and ensure traffic safety. 1 Selected Topics 1.1 Group Profile Shanghai hub workshop CIR equipment QC research team in Table 1.
