本文介绍数字通信系统中一个节点的性能监测系统的微处理机实现。性能监测系统是以系统控制的分级概念为基础的,其中各个最低级节点含有把本地状况报告给高一级节点的设备监测器。由微处理机系统完成的监测功能包括:模拟电压测量、每单位时间事件计数、统计分析、告警扫描以及数据向控制节点的串行传递。该设计的好处是可以增进监测系统的可靠性和灵活性,减少控制地点的计算量,减少遥测数据以及系统所需要的硬件。
This article describes the microprocessor implementation of a node performance monitoring system in a digital communication system. Performance monitoring systems are based on a hierarchical concept of system control where each lowest level node contains a device monitor that reports local conditions to a higher level node. The monitoring functions performed by the microprocessor system include: analog voltage measurement, counting of events per unit time, statistical analysis, alarm scanning, and serial transfer of data to the control node. The benefits of this design are to increase the reliability and flexibility of the monitoring system, reduce the amount of control at the control site, and reduce the telemetry data and the hardware required by the system.
