Research and implementation of LKY-TH lineside electronic unit

轨旁电子单元是应答器控制接口的关键设备,基于自主化硬件平台,对国外设备进行优化创新,采用二取二结构进行模块化设计,研发LKY-TH型轨旁电子单元。该设备周期性的从外部设备接收应答器传输报文,通过处理模块、监测模块、输出模块,按照接口“C”规范连续向有源应答器传输报文,实现向车载设备发送信息,同时集成电缆开、短路检测,和运行日志实时记录功能。目前,该设备已通过室内实验及白乌线综合测试,并取得了国际SIL4级安全认证。测试结果表明:该设备既能高效传输控车信息,可靠性及可维护性较国外轨旁电子单元也有明显提高。

The linsinde electronic unit is the key device of the transponder control interface.Based on the autonomous hardware platform,it adopted the two-two structure for modular design,optimized and developed the LKY-YH LEU for the characteristics of foreign equipment.The device periodically received the transponder transmission message from the external device,and continuously transmitted the message to the active transponder according to the interface“C”specification through the processing module,the monitoring module,and the output module,so as to transmit the variable information to the in-vehicle device.At the same time,it integrated cable open-circuit detection and runs log real-time recording.The equipment passed the indoor test and Baiwu line comprehensive test and obtained the international SIL4 safety certification.The test results show that the equipment can realize the efficient transmission of ground-vehicle information,reliability and maintainability compared with foreign LEU.There is also a significant increase.
