摘　　要：本文介绍了一种基于AT89C51单片机,利用AD590对多路温度采集,并进行温度的控制与检测。为了节省端口,加大以后单片机扩展功能,本系统将传感器的数据用串行方式输入单片机。系统中通过控制按钮实现了实时设定各路的不同报警温度,并且实现多路与任一单路温度显示切换,从而既可以进行多路的检测又可以进行任一单路的监控。在温度超过设定温度时可以对报警温度和实际温度交替显示,从而给予更多的信息.按钮结构简单、应用灵活、易扩展,很大程度上提高了自动检测的效率,使本系统更加的智能化、人性化。Multi-channel temperature detection alarm system based on AT89C51 was introduced. In order to save ports, enlarges monolithic integrated circuit to expand the function later, the data series of sensor system enter the line SCM. Systems through the control button to achieve the real-time setting of all the different alarm temperature, and the realization of multi-cbannel or single switch temperature display, which can carry out multi-channel detection and also can be carried out as a one-way monitoring. When the temperature was reported to the police, the temperature and the actual temperature demonstrated in turn, thus gives more information. The button structure simple, the application nimble, easy to expand, enhanced the automatic detection efficiency to a great extent, causes this system even more intellectualization and humane.
