基于单片机的多点温度测试系统摘 要 集成电路的大规模进展对单片机控制电路的实际运用有着巨大的推动作用。单片机具有体积小、重量轻、价格便宜、低功耗、控制功能强及运算速度快等特点，使其在测控系统、智能仪表、机电一体化产品、智能接口等方面具有较广泛的运用。以单片机为核心，运用温度传感器可完成对温度采集，并进行相应的处理。本系统利用 4 片温度传感器 DS18B20 把所测得的温度发送到 AT89C52 单片机上，通过单片机的处理发送到显示单元进行显示。系统运用单片机进行温度上下限设定，对各点温度进行测控报警，运用主从分布式思想，实现温度的远程控制，构成多点温度检测系统。关键词 单片机，温度传感器，多点温度检测ABSTRACTThe practical application of large-scale development of the integrated circuit chip control circuit has a tremendous role in promoting. MCU with a small size, light weight, inexpensive, low-power, control and computing speed, has a wider use in the monitoring and control systems, intelligent instruments, mechanical and electrical integration products, intelligent interface. With the single chip processor as the core, the application of temperature sensor for temperature acquisition can be completed, and carry on corresponding processing.This system, using four slices of DS18B20, sent the temperature measured by the temperature sensor DS18B20 to AT89C52 single-chip computer, through the MCU processing, the temperature is sent to the display unit to display. The system uses the MCU to set upper and lower temperature, to measure and control the point temperature and alarm. At the same time, use the main distributed thought to achieve remote control of the temperature, and to constitute a multi-point temperature detection system.
