目前,典型的温度测控系统由模拟式温度传感器、A/D 转换电路和单片机组成.由于模拟式温度传感器输出的模拟信号必须经过A/D 转换环节获得数字信号后才能与单片机等微处理器接口,因而使得硬件电路结构复杂,成本较高.而以DS18B20 为代表的新型单总线数字式温度传感器集温度测量和A/D转换于一体,直接输出数字量,与单片机接口电路结构简单,广泛使用于距离远、节点分布多的场合,具有较强的推广应用价值.
本文介绍的饮水机温度控制系统以单片机(AT89C51)为核心,使用DS18B20对温度进行采集,并且控制固态继电器SSR对加热管进行加热,用LED数码管进行显示,从而达到对温度的控制.本系统测温范围为20~90 ℃,精度误差在1 ℃以内,具有测温精度高,控制性能良好等特点.

Abstract: At present typical temperature measurement and control system consists of analog temperature sensor, A/D converter, and MCU. Since the analog signals output from analog temperature sensor must be undergone A/D conversion so that being able to interface with microprocessor, such as MCU, the hardware circuit is relatively complex and the cost is higher. On the other hand the novel single-bus digital temperature sensor represented by DS18B20 sets the temperature measurement and A/D conversion in one unit, directly outputs digital values, and has a simple interface circuit structure, so is widely used in the fields where long distance and multiple nodes are required, and has strong deployment value.
The temperature control system for drinking machine presented in this paper takes AT89C51 MCU as the core, uses DS18B20 to acquire temperature information, controls solid-state relay, SSR, to heat the heating tubes, and utilizes LED digitron to display, so as to realize the control of temperature. The temperature measurement range of this system is 20~90℃, the precision error is within 1℃, so it features high temperature precision and good control performance.
