摘要
针对CINRAD/CA型新一代天气雷达运行过程中存在的接收机、发射机、伺服系统等分系统供电不能进行远程控制的问题,设计实现了基于PLC的新一代天气雷达远程控制系统。系统在不改变雷达原来结构、不影响雷达性能与技术指标的情况下,基于西门子S7-1200PLC控制器,通过控制继电器开关间接控制主回路交流接触器,实现雷达机房接收机、发射机、伺服系统等分系统供电运行状态的实时监测和远程一键式开关机自动控制。在保证雷达观测数据传输及时性和可用性的同时提高雷达技术保障人员对雷达维护的时效性,为新一代天气雷达观测站无人值守提供一种可靠的技术手段。
In view of the problem that the power supply of receiver,transmitter and servo system of CINRAD/CA of the new generation weather radar cannot be controlled remotely at present,a new weather radar remote control system based on PLC is established and implemented.Based on the Siemens S7-1200 PLC controller,the system indirectly controls the main circuit AC contactor by controlling the relay switch without changing the original structure of the radar,and without affecting the radar performance and technical indicators,to realize the real-time monitoring of the power supply operation state of the radar room receiver,transmitter and servo system,as well as the automatic control of the remote one-key switch.While ensuring the timeliness and availability of radar observation data transmission,the efficiency of radar technology support personnel for radar maintenance is improved,which can provide a reliable technical means for the unattended operation of the new generation weather radar observation stations.
