Abstract:
A computerized system with 89C52 as the core is designed for practical acquisition of temperature. The system adopts J type electric thermocouple as thermometric component and realizes effective compensation of the temperature at the cold end of thermocouple by using temperature sensor AD590 of integrated circuit. Thus it can be improved in accuracy and stability and noise proof performance. Starting from engineering reality, a study is made on its choice of components and circuit design. While the hardware circuit is given as the core, an expandable circuit is presented for acquiring and processing multichannel data and for giving alarm. The design has realized low cost and far distance transmissible temperature scan.
