基于单片机的温度控制系统的设计

Based on monolithic integrated circuit temperature control system design

系统设计采用AT89S51单片机,配以DS18B20数字温度传感器,该温度传感器可自行设置温度上下限。单片机将检测到的温度信号与输入温度的上、下限进行比较,由此判断是否启动继电器以开启设备。设计中还加入了常用的数码管显示及状态灯、显示灯常用电路。

The designed system with the single-chip AT89S51 and with DS18B20 digital temperature sensor,The temperature sensor can set up their own temperature collars.SCM will detect that the temperature of the input signal and temperature,the lower comparisons this judgment whether to activate the relay to open the equipment.The design also includes commonly used digital display and control state lights commonly used circuit.
