广播发射台节传系统串口服务器功能应用探析

Radio Transmitting Station Transmission System Section of Serial Server Function Application

随着知识经济和网络经济时代的到来,广播发射台节目传输机房智能化管理已经成为实现广播发射台安全优质播出的根本保证。本文介绍了串口服务器在广播发射台节传系统的功能以及应用。通过串口服务器把节目传输机房的各部分设备连接在一起,利用计算机技术实现实时监控和管理节目传输系统中各设备的运行状况以及信号传输情况,同时通过上级计算机联网实现对整个机房的集中控制。本文以MOXA NPort5610串口服务器为例,对节目传输机房中的音频自动切换、卫星接收机、GPS网络授时、UPS运行状态、节目调度和网管监控应用进行了探析。

With the advent of the knowledge economy and network economy era, broadcasting stations transmit prog-rams intelligent room management has become to achieve safe and high quality broadcasting stations broadcast the fun-damental guarantee. This article describes the serial servers in radio transmitting section transfer system functions and applications. Through the serial port server connect various pieces of equipment program transmission room together, using computer technology to achieve operational status of each device and signal transmission real-time monitoring and management program transmission system, and networking to achieve centralized control of the entire room by the superior computer. In this paper, MOXA NPort5610 serial server, for example, the program transmission room audio automatically switches, satellite receivers, GPS network time, UPS operational status, program scheduling and network monitoring applications of China.
