摘　　要：介绍一种基于PC串口通讯的简易测温系统,该系统由数字温度传感器DS18B20,通过单总线方式连接组成测温网络;PC机通过串口协议对单片机进行控制,实现测温.PC机可视化程序可以进行添加、删除、修改测温点;对测温点添加备注位置信息;循环测温并实时越限报警,显示各测温点的温度曲线;系统人机界面友好,实际效果好.A multi-sensors temperature system, which constrncting sensors network by digital thermometer DS18B20 with one-wire technique, basing on serial communication is introduced. Using user-defined serial protocol, PC controls MPU to finish temperature measurement. The PC visual program interface can： add, delete, modify sensor node; add the position information for sensor node; circularly measure temperatnre for sensor nodes and alarm when it is out of range; show the temperature curve of sensor nodes etc. it has a friendly interactive interface with good effectiveness.
