| 摘 要： | 介绍了以AT89S52单片机为核心的温度控制系统的工作原理和设计方法。系统由芯片DS18B20采集温度信号传输给微控制器,通过外围设备LCD1602显示现场温度值,并设计上位机程序通过串口通信实时获取温度。系统设计包括硬件电路设计、软件设计。单片机程序采用C51,在KEIL开发环境中调试通过完成;PC后台软件采用VB6.0完成。给出了前后台软件设计流程图。最后给出了设计实现的硬件实物图和采集到的前后台温度显示结果。

| Abstract: | A temperature measuring & transmition system controlled by SCM and PC is designed.At front end,the real-time temperature data acquired and converted to digital type through DS18B20 sensor is sent to SCM,and then displayed on LCD1602 module.In addition,the acquired temperature data is transmitted to back-end PC via RS232 interface,thus to implement its display,storage and follow-up processing.The SCM firmware is constructed with C51,and bebuged in KEIL development platform.The back-end software is designed w... |
