本系统设计以浴室温度控制为出发点，采用模块化设计，以使用最为广泛的单片机STC89C52作为系统核心；采用测量精度高、对环境要求小的Pt100温度传感器来采集温度；通过模数转换芯片ADC0809将采集到的温度转换成数字量送到单片机中进行数据处理；采用三个独立按键进行温度参数设定；使用4位共阴极数码管显示器来动态显示系统采集到的实时数据和设定的温度值；输出控制经过数模转换芯片DAC0832将数字量转换成对应的模拟量，然后连接功率放大器来进行功率放大，通过电热管对浴室中水箱内的水进行加热，冷却采用的方式是自然冷却；液位控制以保护的方式体现，通过设定水箱液位的上限和下限，进行液位保护；还有声光报警装置，当温度过高或者过低时，启动声光报警装置。在控制算法方面，采用比较法，使温度控制箱的控制准确。通过以上设计可以使温控箱的温度测量与控制较传统的温控箱有很大改善。

Abstract
With the social development, modern engineering for temperature control have high demands. Conventional temperature control systems generally use conventional analog circuit temperature control technology, resulting in temperature inside temperature control accuracy of less than the corresponding requirements. So, the design of a control system with a high precision temperature will have a very important significance. Bath industry throughout the country, were reasonable temperature control is undoubtedly of great social benefit. This paper analog bathroom temperature control box for temperature control, so that it can better serve the public.
From the practical engineering applications as a starting point, the use of modular design. With the most widely used microcontroller STC89C52 heart of the system. Measured using a wide range, high measurement accuracy Pt-100 temperature sensors collect temperature. By analog-digital conversion chip ADC0809 to convert analog to digital data processing to microcontroller. Using three separate buttons for temperature parameter settings. Using four common cathode LED display shows the temperature value of the system to dynamically collect real-time data and settings. Output control after DAC0832 digital-analog converter chip to convert digital to analog, then through the power amplifier power amplifier, connected to the electric heating tube temperature. Cooling using natural cooling way. Level control and protection Embodied by setting the upper and lower water level, liquid level protection. There are sound and light alarm device, when the temperature is too high or too low, the start sound and light alarm devices. In terms of the control algorithm, by comparison, the temperature control box control is accurate. Through the above temperature control box design allows temperature measurement and control than traditional temperature control box control system has greatly improved.
