基AT89S52 单片机温度控制系统设计 Design of TemperatureSystem Based on Microcontroller Unit AT89S52 摘 要 在工业生产过程中，有些设备需要严格要求现场环境的标准性和可行性。温度是一个非常重要的物理量，温度控制失误就可能引起生产安全、产品质量、产品产量等一系列问题，因此对温度的检测的意义很重要。无线传输是一种将有效数据传输至远方的一种有效方法，所以使用无线传输的测温系统可以对生产环境的温度进行无线采集并且能够使操作员可以远距离实时了解被测现场的温度变化情况。 本设计以AT89S52单片机为核心的温度控制系统，温度信号由温度芯片DS18B20采集，并以数字信号的方式传送给单片机，在由单片机控制nRF905进行数据的无线传输至另一个单片机，通过显示及过限报警，然后使用红外控制器调节模拟空调，达到规定温度后自动解除警报。文中介绍了该控制系统的硬件部分、包括：温度采集电路、温度控制电路、无线通信电路和一些接口电路。单片机通过对信号进行相应处理，从而实现温度控制的目的。文中还介绍了软件设计部分。 关键词： 单片机 无线通信芯片 温度芯片 温度控制 Abstract In the industrial control field, people often need to collect a lot of field data, Temperature is a very important physical quantity, so temperature control failure could lead to a series of problems such as production safety, product quality, product yield and so on, so the meaning of the temperature detection keeps growing. Wireless transmission is an effective way to transfer the data far away, so people can apply the wireless transmission of high-precision temperature measurement system on the production environment for wireless transmission and operators can have access to the real-time temperature changes, thereby enhancing production efficiency. This design take AT89S52 monolithic integrated circuit as core temperature control systems. The temperature signal by the temperature chip DS18B20 gathering, and transmits by digital signals way for the monolithic integrated circuit，and control NFR905 wireless data transmissionby the microcontroller to the temperature data. Automatically disarm the alarm display and over-limit alarm, then the use of infrared controller to adjust the simulation of air-conditioning, to achieve the specified temperature.In the article introduced this control systems hardware part, including:Temperature examination electric circuit, temperature-control circuit, wireless communication electric circuit and some interface circuit. The monolithic integrated circuit through carries on c
