Design and Realization of Digital TV Transmitter Controller Communication System

The structure of DCS control system for digital TV transmitter is presented in this article,the system of communication RS-485 master-slave multi-chip communication mode.In other words,the main control system exchanges data with several slave system through RS-485.In order to improve the reliability,and to prevent deadlock phenomenon,the measures of overtime-dealing are used.It is proved to be very reliable after experiment and field application to meet the request of communication in control system of transmitter.
