电力载波通信是以现有的电力电缆为载体实现数据交换的一种通信方式。随着网络通信技术的发展,这种由于不需要铺设通信专线,且可以有效降低系统的运行成本的通信技术开始在工业自动控制领域获得应用。针对现有铁路道岔液压转辙机油压检测方法存在的不足,设计了一种基于PL3201电力线载波扩频通信的铁路道岔转辙机液压检测系统,实现了对铁路液压转辙机健康状况的实时在线监测。
Power line carrier communication is based on the existing power cable as a carrier for data exchange. With the development of network communication technology, the communication technology that does not need to lay a dedicated communication line and can effectively reduce the operating costs of the system is beginning to be applied in the industrial automatic control field. Aiming at the shortcomings of hydraulic detection method of hydraulic switch for railway turnout, a hydraulic detection system for railway switch ICM based on PL3201 power line carrier (PLC) spread spectrum communication is designed to realize the real-time Online Monitoring.
