摘要 发射台自动监控系统运行在各个发射台里,电磁环境复杂,干扰严重,给数据采集和设备控制带来了很大的麻烦,如果处理不好,容易发生取样信号无规律跳动、频繁误告警等现象。以开发的多套发射台自动监控系统为例,分析了发射台建设自动监控系统时遇到的电磁干扰类型及解决办法。 Automatic transmitter control system is running on each transmitter, the electromagnetic environment is com- plex, serious interference to the data acquisition and device control is a big trouble, if handled improperly, prone to irregu- lar sampling signal beating, often mistaken for alarm and so on. Taking several sets of emission automatic monitoring system developed as example, the type of electromagnetic interference and solutions that may encounter in the process of building automatic monitoring system are analyzed.
