摘要
介绍电能自动计量系统中远程数据采集的设计方案 ,提出在Delphi 5 .0下利用通信控件和线程类实现前置机与电能量采集器串行通信的方法 ,并给出IEC6 0 870 - 5 - 10 2规约的解释和程序实例。
The design of remote energy data acquisition module which is the main part of energy metering system is presented. The method of achieving serial communication between host computer and energy collector by using communication component and Tthread class with Delphi 5.0 is proposed.Finally, the IEC60870-5-102 protocol is discussed. The program example is given.
