摘要
安播预警终端是广电机房普遍使用的预警信息发布平台接收设备,是上下联动搞好安全播出监管平台的关键设备之一,其时间不同步、不精确是普遍存在亟待解决的问题。本文介绍了一种简单实用的方法,通过串口通讯转换器(RS232或RS485串行接口转换USB总线接口),安装校时软件DIY解决安播预警终端的自动校时问题,供同行借鉴和参考。
Safe broadcast warning terminal is the receiving equipment of warning information release platform commonly used in radio and television room.It is one of the key equipment of security broadcast supervision platform linking up and down.The time non-synchronization and inaccuracy of the terminal is the common problem to be solved.This paper introduces a simple and practical method to solve the problem of automatic time calibration of broadcast warning terminal which installs time calibration software DIY through serial communication converter(RS232 or RS485 serial interface to USB bus interface).This method can be used as a reference for peers.
