广播发射台站天线交换控制系统控制原理浅析

Analysis on the Control Principle of Antenna Exchange Control System at Broadcast Station

代播机是广播发射台站里安全播出的一个重要保障,可有效的缩短发射机停播时间,代播机在使用时需要经过交换开关上主播机天线,因此设计一套稳定可靠控制交换开关的系统极为重要。本文从硬件的控制原理和软件方面对交换控制系统进行了浅析。

Backup broadcast transmitter is an important guarantee for the safe broadcasting of broadcast stations.It can shorten the time of the break of principal broadcast transmitter.When the backup broadcaster transmitter act as a substitute for the principal broadcaster,It needs to connect with the antenna of the principal broadcast transmitter through the exchange switch.Therefore,it is extremely important to design a stable and reliable control exchange switch system.This paper analyzes the exchange control system from the aspect of hardware control principle and software.
