摘　　要：单片机测温系统往往需要实时时钟以确定所测温度的当前时间,而对于实时时钟,设置的时间量很多,传统的按键设置时间不但设置繁琐,而且精度也不高。另外单片机系统通过外接液晶模块显示的内容有限,针对这一问题设计了一种利用Visual Basic在PC端的温度监测和控制界面。该控制界面通过MSComm控件实现PC机与单片机测温系统的串行通信,同时实时显示各路所测温度值,并可以通过该控制界面快速、准确地实现对下位机系统的时间设置。In order to ensure the time of MCU temperature detecting system often needs RTC chip,but there are many parameters to set to RTC chip.It is complex to set time through traditional key and the precision of the method is poor too.The display content is limited by connecting with LCD module.The design of control surface on PC by Visual Basic is to solve these problems.The control interface implements serial communication between PC and MCU temperature detecting system through MSComm controller.The interface displays the detecting temperatures and sets time of the MCU system quickly and correctly.
