This paper introduces a kind of intelligent temperature control meter design method,system structure and software design,the intelligent temperature control meter adopts the STC12C5A60S2 microcontroller as the core,uses the high precision PT1000 platinum resistance as temperature sensor,through the built-in 10 bit A/D converter to achieve collection to the voltage signal,comparing target temperature value and the actual the temperature value by the incremental PID arithmetic to get the corresponding control data,can make the temperature control in and the target temperature error within 2 ℃,the control precision is high,the reliability is good,in addition,the intelligent temperature control meter also has the advantages of strong versatility,convenient connection control many kinds of heating equipment,the modular programming,parameter detection and modification adjustable and flexible operation.
