摘 要
该项目背景是液压操动机构试验状态在线监测与故障预警研究。对断路器终端温度进行实时采集，并将其显示于上位机上。但由于现场限制，需要通过RS-485总线传输数据，并经由主控板做终端与上位机之间的通信，上位机的功能是对断路器电的温度进行实时监测。
本文主要工作是利用C++Builder6.0软件编写断路器温度监控系统的人机交互界面，该界面的主要功能有通过RS-232串口将数据接收进来，并将该温度数据显示在数据表上，还需调用数据表中的数据显示成曲线。

ABSTRACT
The background of this project is testing the temperation and hydraulic operation（液压操动机构 ）testing condition Receiving emperature index is an important index of many working environment, therefore, temperature monitoring has been widely used in industrial field. This topic using C++Builder6.0 to build up the temperature monitoring system for circuit breaker operation interface, this software is very easy to use. What's more,its function is powerful,especially with one's own knack in interface design, WINDOWS programming, database programming etc.And it can't be compared by some of the other software development tools.
The main function of PC is to receive the temperature data collected by the lower control machine through the RS-232 serial port, and displayed in the data sheet. Also it should be plotted into curves by SimuCurves control.
In addition, this system uses C language programming, the past software using assembly language.But assembly language is readability and portability, and high-level language is difficult to realize the direct operation of computer hardware.However C language combines the characteristics of these two kinds of language.It has the characteristic of concise,convenient,flexible,compact. And the target code it generated has high quality and high efficiency.It has become one of the most popular programming languages in the world today.
KEY WORDS: temperature, RS-232, C++ Builder6.0，PC, monitor
