摘要
温度测量系统应用广泛,涉及到各行各业的各个方面,在各种不同的领域中都占有重要的位置。从降低开发成本、扩大适用范围、系统运行的稳定性、可靠性出发,设计一种以PT100铂热电阻为温度信号采集元件、EW78E58单片机为控制核心、OCMJ4×8C液晶显示器为显示器件的温度测量系统。该测量系统不但可以测量室内的温度,还以测量液体、种子等内的温度,在实际应用中,该系统运行稳定、可靠,电路设计简单实用。
The measurement systems are applied wildly, involving various occupations and aspects. It holds the important position in the different fields. According to the principle of system running stability, security, stabilization and credibility, a kind of temperature measurement system in which using the PT100 as the temperature signal gathering part,EW78E58 as the control center, and the OCMJ4 × 8C （Liquid Crystal Display） as the display component are designed. Not only this measurement system may measure indoor＇s temperature, but also may measure the temperature of liquid and seed. It runs stably,credibly in the practical application and the design of circuit is simple and applied.
