| Abstract: | Aim at the requirement of thermal meterage, an automatic thermal meterage meter with AT89C52 SCP as its core was developed. The function of the meter, its hardware structure and software design and application were introduced . In the design the intelligent IC card technology was employed which can charge automatically. The external data memory E PROM was used to guarantee the accuracy of the meter and the calendar clock chip PCF8583 was used to preset the time of turning on or off. Its temperatrure accuracy rating is 0. 3C, and calculation error is 0.65%. |
