二十一世纪以来,法国THALES公司生产的RSM970S单脉冲二次雷达相继在我国多个地方安装并投入使用。2007年11月在合肥地区安装使用了该型号的航管二次监视雷达。目前这套雷达在合肥地区是本场航管监视数据源。其中AA2000机柜作为天线的控制驱动系统,负责给天线马达提供电源及启停功能,向雷达设备监控系统提供天线的运行状态数据,在整套系统中起到了举足轻重的作用。为此,将对如何使用PLC替代AA2000机柜的安全链,以及如何进行硬件配置和程序优化设计进行研究分析。
Since the 21st century, RSM970S single pulse secondary radar produced by France THALES Company has been installed and put into use in many places in our country one after another. November 2007 installed in the Hefei area using this type of secondary air surveillance radar. This radar is currently in the Hefei area of this ATC data source. The AA2000 cabinet acts as a control drive system for the antenna and is responsible for providing power to the antenna motor and start-stop function, and providing the antenna operation data to the radar equipment monitoring system, playing a decisive role in the entire system. To do this, research will be conducted on how to replace the safety chain of the AA2000 with a PLC and how to configure the hardware and optimize the program design.
