Anti-theft intelligent charging electric meter

Abstract

The invention relates to an anti-theft intelligent charging electric meter. The anti-theft intelligent charging electric meter comprises a main body; and an IC card reader, a magnetic latching relay,a switch, a cover, a display screen, a buzzer, a communication module, a communication card slot, a DSP processor, a cover opening prevention assembly, a blocking assembly and an anti-magnetic interference assembly which are arranged on the main body. The cover opening prevention assembly includes pushing blocks, support rods, a baffle, a first spring, a bottom plate and a contact mechanism. The blocking assembly comprises a motor, a circular gear, a strip gear and a blocking rod. The anti-magnetic interference assembly comprises a connecting block, a second spring, an iron ball and a copper pipe. The anti-theft intelligent charging electric meter is ingeniously designed and highly feasible. When the cover is artificially damaged or forcibly opened, the buzzer can promptly alarm, then communication alarm can be performed through the communication module and an alarm call, and through the anti-magnetic interference assembly, under the environment with a magnetic field capable of affecting the magnetic latching relay, the anti-magnetic interference assembly can send an electrical signal to the DSP processor so as to alarm.

Description

technical field [0001] The invention relates to the field of electric meters, in particular to an anti-theft intelligent billing electric meter. Background technique [0002] Smart billing meter means that the user holds the IC card to the power supply department to pay for electricity purchase, and the power supply department uses the electricity sales management machine to write the purchased electricity into the IC card, and the user holds the IC card to swipe the non-contact IC card in the sensing area The power supply is closed by a magnetic latching relay. After the power is supplied, the card is taken away. When the remaining power in the meter is equal to the alarm power, the switch is turned off and the power is reported. However, there is a risk of power theft. People often use strong magnetic interference and electronic breakdown. In the process of video signal analysis and control, due to the lack of functions such as signal enhancement and denoising, the reliabi...

[0002] Smart billing meter means that the user holds the IC card to the power supply department to pay for electricity purchase, and the power supply department uses the electricity sales management machine to write the purchased electricity into the IC card, and the user holds the IC card to swipe the non-contact IC card in the sensing area The power supply is closed by a magnetic latching relay. After the power is supplied, the card is taken away. When the remaining power in the meter is equal to the alarm power, the switch is turned off and the power is reported. However, there is a risk of power theft. People often use strong magnetic interference and electronic breakdown. In the process of video signal analysis and control, due to the lack of functions such as signal enhancement and denoising, the reliability of video processing is greatly reduced, and the reliability of the system is further reduced.
