DESIGN OF TEMPERATURE INTELLIGENT CONTROL SYSTEM BASED ON AT89S52

摘要：

The temperature control system designed is mainly based on microcontroller-AT89S52, using sub-PID control algorithm, to achieve accurate temperature measurement and control.This system is mainly composed of temperature sensor, signal conversion and conditioning circuits, A/D module, microcontroller.D/A module, temperature buttons circuit, data display module, thyristor trigger circuit, optical isolators, crystal Gateway tube drive circuit and implementation agencies.This paper describes the hardware design of temperature control system and software realization method in detail.The test results show the temperature control system designed can achieve a more accurate measurement of temperature and runs stably.The technology adopted in the system is practical and worthy of market.
