The Design Of Medium Wave Broadcast Transmitter Monitoring System

With the particularity of radio and television, to finish the security task of medium waves broadcasting station, this article designed a medium wave transmitter monitoring system, the aim of this system is to monitor the audio siginal, broadcasting and medium wave transmitter to ensure the broadcasting safety.First, the system collects the signals, then we through the processing and monitoring to achieve signal acquisition by AT89S52 microprocessor and its peripheral circuits. Including:an audio signal acquisition circuit, a transmitter running parameters acquisition circuit, voltage standing wave ratio acquisition circuit, power acquisition circuit, system monitoring and alarming circuit; the software programming in C language to implement, use Keil C51 software for software programming; hardware and software are combined to complete the monitor of audio siginal, real-time broadcasting and medium wave transmitters.In this article, we elaborated the monitoring system of hardware design and software programming.
