Description: 及时准确地得到温度信息并对其进行适时的控制，在许多工业场合中都是重要的环节。所以本文设计了一种以89C51单片机为核心的水温控制系统。方案是通过比例算法得出控制量，然后以脉宽调制波的形式输出给功率器件。并且为了保证系统稳定运行，在软硬件方面都采取了相应的措施。
本设计的主要特色：
1、采用了AD674的12位AD转换方法采集水温,使得采集范围与精度大大增加；
2、采用液晶显示，使得在优化显示的同时，降低了电路的功耗；
3、采用比例算法，降低了温度超调量。

-Receive timely and accurate temperature information and its timely control, in many occasions in the industry are all important aspects. Therefore, this article has designed a single-chip microcomputer 89C51 as the core temperature control system. Algorithm is derived through the ratio of the volume control, and then to the form of pulse width modulation wave output to power devices. And in order to guarantee stable operation of the system in hardware and software have been taken corresponding measures. The main feature of this design: 1, using the AD674 12-bit AD conversion method of collecting the water temperature, making acquisition greatly increased the scope and accuracy 2, the use of liquid crystal display, makes the optimization show that at the same time, reducing the power consumption of circuits 3, proportional algorithm, reduces the temperature overshoot.
