摘　　要：采用51系列单片机STC89C52RC为主控制器,DS18B20为数字温度传感器,将温度传感器密封入不锈钢壳体内实现水温检测,用LCD1602双行英文字符液晶显示实测温度与报警温度的上下限值。设计了系统的硬件电路与控制程序,实现了对水温度的测量,显示,和报警等功能。经测试后,证明其工作可靠、准确度高、体积小,携带方便,具有实用价值。The 51 series microcontroller stc89cJ2rc is used as the main controller, and the DSI8B20 is used as the digital temperature sensor. The temperature sensor is sealed into the stainless steel shell to carry, out the body temperature detection, and the limiting values of actual temperature and alarm temperature are displayed by the double line of English characte~ of LCD1602. The hardware circuit and the control program of the system are designed, and the measurement, display, alarm and other functions of the water temperature are realized. After testing, it is proved that the work is reliable, the accuracy is high, the volume is small, the carrying is convenient, and it has the practical value.
