Smart electric meter capable of preventing electricity from being stolen

Abstract

The invention discloses a smart electric meter capable of preventing electricity from being stolen. The smart electric meter comprises a shell, a voltage and current detection module, a drive module, a charging and discharging control module, a metering module, a data processing module, an I / O module, an infrared sensor, a video collecting module, a display module, a storage module, a keyboard, a wireless signal communication module, a storage battery module and a cover opening signal generator. The voltage and current detection module, the drive module, the charging and discharging control module, the metering module, the data processing module, the I / O module, storage module, the wireless signal communication module, the storage battery module and the cover opening signal generator are all arranged in the shell. The system has the advantages that electricity metering precision is high and the system operates stably; when the electric meter is adjusted illegally or out of line, a photo can be taken for an operator in time for storage, remote alarming can be carried out in time through a wireless transmission system, and accordingly the phenomenon of stealing the electricity can be effectively avoided.

Description

technical field [0001] The invention relates to an anti-theft electricity smart meter, which belongs to the technical field of power transmission measurement. Background technique [0002] Electricity is one of the most important energy sources at present. It is widely used in industrial and agricultural production as well as in the daily life of residents and commercial activities. However, most of the power measurement methods currently used are to install electric meters near power users for measurement. In the process of use, there are often the phenomenon of stealing electricity by changing or setting the meter, resulting in inaccurate electricity metering, causing the national grid system to suffer large economic losses, and the act of stealing electricity is also to a certain extent Threatening the operation safety of the power grid, but because the existing electric meters, whether they are mechanical meters or electronic meters, do not have effective self-protection...

[0002] Electricity is one of the most important energy sources at present. It is widely used in industrial and agricultural production as well as in the daily life of residents and commercial activities. However, most of the power measurement methods currently used are to install electric meters near power users for measurement. In the process of use, there are often the phenomenon of stealing electricity by changing or setting the meter, resulting in inaccurate electricity metering, causing the national grid system to suffer large economic losses, and the act of stealing electricity is also to a certain extent Threatening the operation safety of the power grid, but because the existing electric meters, whether they are mechanical meters or electronic meters, do not have effective self-protection functions and alarm functions, when electricity theft occurs, they cannot immediately alarm and Provide necessary evidence for future case detection work, resulting in repeated prohibition of electricity theft, and the difficulty of case detection is relatively large
