基于电子技术的水温自动控制系统

Water Temperature Sutomatic Control System Based on Electronic Technology

水温控制系统的主控模块采用的是STC12C5A60S2系列单片机;温度采集采用的是控温精度为0.2℃的DS18B20温度传感器;显示装置采用液晶显示模块。具体实现过程为:首先预设温度,温度传感器对水温进行测量,将测量温度实时显示,并通过I/O串口输送给单片机,单片机把送来的数据与预设温度数据进行比较,如果低于设定的温度则启动功率电路进行加热,直到设定值。当水温超出预设温度范围时报警器报警。还可以根据需要改变预设的温度值,实现温度自动调节目的。

The main control module of the water temperature control system is STC12C5A60S2 single chip. Temperature acquisition is used to control the accuracy of 0. 2℃ temperature sensor DS18B20. Display device using liquid crystal display module. Specific implementation process is that,firstly presetting temperature,measuring water temperature with temperature sensor and measuring the temperature in real time. It is to be delivered to the microcontroller with the help of I/O. Single chip microcomputer sent data comparing with the preset temperature data. The set is begin to heat power circuit when the temperature decrease. When the temperature is beyond the preset range,the alarm go off. Automatic temperature adjustment come true.
