Design and Implementation of External Interface Circuit in the Monitoring and Control System of MW Transmitter

对外接口电路是发射机与外部软硬件系统设备进行信息交互的桥梁和窗口,是实现发射机自动监控不可或缺的重要组成部分。本文以XAM-10A型中波广播发射机为例探讨了其监测控制系统对外接口电路的设计与实现问题,根据发射机涉及的状态参量和指令信息的对外输入/输出特性类型,完成了对外接口电路关键电路的设计和解析,该设计方法可以作为相关机型监测控制系统对外接口电路设计的参考。

The external interface circuit is a bridge and window for the transmitter to interact with the external software and hardware system equipment. It is an indispensable part of the automatic transmitter monitoring. In this paper, the design and implementation of the external interface circuit of the XAM-10 A type medium wave broadcasting transmitter is discussed. The design and analysis of the key circuit of the external interface circuit is completed according to the status parameters involved in the transmitter and the type of the external input/output characteristic of the instruction information. The design method can be used as a reference for design of external interface circuit of the related model monitoring and control system.
