家用电器用电监测仪的研发

Research and Development of Household Appliances Electricity Monitor

合理用电、节约用电已经成为节能减排工作的重中之重。为配合智能电网对智能检测的要求、实时监测家用电器的用电情况、提高人们的节电意识,本文从硬件、软件两方面确定了家用电量监测仪的设计思路,分析了不同电量检测芯片的特点,设计了硬件、软件结构,采用电源、电能校验装置对设计样品进行了检定。检定结果显示该设备符合精度要求,可用于家电的电流、电压、功率的实时监测,且易操作,成本小。

Rational use of electricity and saving electricity have become a top priority of energy saving and emission reduction. According to intelligent testing requirements of smart grid, real time monitoring of electricity consumption of household appliances and raising people＇s awareness of energy saving, the idea of home electricity consumption monitor was designed from hardware and software aspects. The paper analyzed the characteristics of different capacity check chips, designed the hardware and software structure and verified the sample using power and energy calibration device. The results show that the device can meet accuracy requirements and be used to real time monitor the current, voltage, power of household appliances. It is easy to operate, and the cost is small.
