摘要
针对广播电视发射台实时监测和运行管理的需求,提出基于SNMP的集中监控系统方案。首先介绍SNMP和BER编码相关知识,重点分析调频Harris发射机的SNMP报文结构,通过开发基于SNMP的发射机数据采集和控制软硬件平台,实现上位机对多台多型号调频和电视发射机的集中监控功能。应用实践表明,该系统能够满足大型发射台站的设备实时监控要求,对提高发射台自台监控水平有着实际意义。
According to the requirements of real-time monitoring and operation management of broadcasting&TV transmitting station,a centralized monitoring system based on simple network management protocol(SNMP)is proposed.In this paper,the related knowledge of SNMP and BER(basic encoding rules)code is introduced and the SNMP message structure of Harris transmitter is analyzed.With the development of SNMP-based transmitter data acquisition and software&hardware control platform,the centralized monitoring function to monitor several multi-model FMs and TV transmitters has been achieved by the host computer.The practical application effect shows that the system can meet the real-time monitoring requirements of large transmitting stations,and has practical significance for improving the self-monitoring level of the transmitting station.
