电力系统智能数据通信-译码适配器的研究

电力系统中直接采用上位微机对智能终端进行实时通信和数据采集时，会出现大量资源浪费和影响监控系统稳定性的瓶颈效应。针对这一问题，提出了与一种具有自采集与数据转存控制的电力系统智能数据通信-译码适配器。该适配器以单片机为核心，充分利用单片机的控制与运算能力，由单片机系统替代微机独立地完成对智能终端的通信、协议辨识、数据收集和解码译码进程，使微机只需通过总线接收经过该适配器解码的数据结果，从而极大地减轻了微机的负担。

Research of intelligent data communication-decode adapter in power system

When the host computer is used for real time data acquisition and communication with the intelligent terminals in power system,the resources are wasted and the stability of the superviosory system is influenced by the bottle neck effect.Regarding to it,an intelligent data communication decode adapter is developed,which can acquire and store the data automatically with a MCU as its core.Making the best use of MCU's capability in control and calculation,the adapter can intelligently accomplish the tasks of communication,protocol identification,and data acquisition and decode.The host computer only needs to receive the decoded data results via ISA bus,and its load is greatly released.
