摘　　要：针对传统电能计量装置精度低、功耗高等缺陷,提出了一种基于SPI、485与红外无线电能计量传输系统设计方案.首先采用电压、电流互感器进行电量参数采集,其次借助高精度电能计量芯片ATT7022B完成电能参数计算,再次选用低功耗PIC16F877单片机作为整个系统控制核心,最后经由485总线完成电能数据远程传输.经过测试表明,系统具有可靠性高、运行稳定、易实现等优点.In the light of disadvantages of low precision and high power consumption of traditional electric energy metering device, based on SPI, 485, an infrared radio energy transmission system is put forward. Firstly, the voltage and current transformers are used to collect the electric quantity parameters. Secondly, the high-precision electric energy metering chip ATT7022B is used to complete the calculation of electrical parameters, low-power PIC16F877 microcontroller is chosen as the core of the whole control system. Finally, the remote transmission of electric energy data is accomplished by the aid of 485 bus. The test shows that this system has the advantages of high reliability, stable operation and easy realization.
