摘　　要：针对目前广泛采用的A/D+MCU测量电网参数的电力监控仪表开发周期长、软件复杂的缺点,本文阐述了一种基于ATT7022A芯片的综合电力监控仪表的实现方案,并给出了电能测量原理、详细的电路组成和软件流程图。该系统可以完成各种电力参数及时、准确的检测和报警,同时具有灵活的远程软件校表功能。The measurement of electrical energy parameters utilizing A/D and MCU is prevailing solution for electric power monitoring. According to the defects of the long develoment cycle and complexity of software, a new method was presented. An ATT7022A system for measurement the electric power parameters was employed in the design of comprehensive electric power monitoring device. It is put forward for the measuring principles of electric power, composition circuits, and the flow process charts of the software applied in the device. The system can detect electric power parameters, alarm real-time exactly and has an advantage that is agile and remote software regulating meter.
