Intelligent electric meter with uncovering alarming function and uncovering alarming method

Abstract

The invention discloses an intelligent electric meter with an uncovering alarming function and an uncovering alarming method.The uncovering alarming method comprises the following steps that at least two of a plurality of cover pressing screws of the intelligent electric meter are provided with sensors or switches respectively, and the sensors or the switches are used for detecting whether the cover pressing screws leave the original positions or not; the number of the triggered sensors or switches of the cover pressing screws is detected in real time; the number of the triggered sensors or switches is judged according to signals detected in real time, when one or more sensors or switches are triggered, an alarm is given, and when more than two sensors or switches are triggered, power-off operation is executed immediately or delayed.According to the method, the number of the dismounted cover pressing screws in the uncovering process is detected, corresponding alarming intervention is carried out according to the number of the dismounted cover pressing screws, the power-off operation is executed after intervention fails, and therefore the uncovering electricity stealing behavior is actively and effectively prevented.

Description

technical field [0001] The invention relates to an intelligent electric meter with a cover opening alarm function and a cover opening alarm method. Background technique [0002] A smart meter is an instrument used to measure electric energy. It has an LCD screen that can display electricity consumption, a pulse indicator light, and a trip indicator light on the surface. In addition to the energy metering function, it also has the function of opening the cover and recording, tripping and communication interfaces. [0003] The existing smart meter has the following problems: the smart meter has the function of recording the opening of the cover, but there is no indicator light for prompting the opening of the cover. Electricity-stealing molecules often steal electricity by opening the watch cover, and then restore the watch cover to be the same as before opening, and it is impossible to distinguish whether it is stealing electricity or not. The power supply department must ch...
