摘　　要：本次设计的温度测控系统采用MCS-51系列单片机中的STC89C58作为微处理器,使用集成温度传感器AD-590采集温度信息,光电耦合双向晶闸管为驱动电路,可精确地采集环境温度信息,稳定性高,抗干扰性强。接受信息后处理器可快速地作出反应,导通驱动电路,实现温度调节。本文从硬件和软件两方面介绍了MCS-51单片机温度控制系统的设计思路,对硬件原理图和程序框图作了简捷的描述。This design of temperature observation and control system uses STC89C58 of the MCS -51 series monolithic integrated circuit as the microprocessor. The temperature information is gathered with the integration temperature sensor AD - 590; the photoelec-tricity coupling bidirectional thyristor is used as driving circuit to precisely gather the ambient temperature information, which with a high stability and strong anti -jamming feature. After accepting the information, the processor can make a fast response to breakover the actuation electric circuit and realize the temperature control. This article introduces the design mentality of the MCS -51 monolithic integrated circuit temperature control system from the two aspects of hardware and software, and makes a simple and direct description on the hardware schematic diagram and the flow chart.
