• According to the electricity metering of civil airports covered bridge equipment, the smart meter is presented based on ATT7022A and AT89C52. The smart meter has the interface of RS485 bus, so it can achieve network control function. Based on the hardware system’s general structure, the design of the three-phase voltage and current measuring circuits and some precautions, we designed the SPI communication interface of ATT7022A and AT89C52, and we gave the software correction flowchart of smart meter. Finally we know that the design of smart meter based on this scheme is simple and effective.
