Modbus是应用于电子控制器上的一种通信协议。该文主要介绍了以上位机PC为核心的基于Modbus通信协议的建筑能耗监控系统的设计，详细阐述了基于Modbus RTU规约的电力参数采集显示系统的软硬件组成和实现。VC++6.0开发环境下编程实现了与下位机的通信，并利用ADO访问SQL数据库，实现了对采集来的数据进行存储、绘图等。

Modbus protocol is a common communication protocol used in the electronic controller. Based on the Modbus com-munication protocol, we designed building energy consumption monitoring systemwhich used a PC as the upper controlling ma-chine.The system hardware components as well as the power parameters acquisition and display based on Modbus RTU protocol are presented. Using VC++6.0 we developed the data communication software between the lowersensers and the upper PC, and used ADO to access the SQL database so as tostore and analyze the acquisition data.
