Chip capable of recognizing high-frequency and strong-magnetism electricity stealing behavior

Abstract

The invention discloses a chip capable of recognizing a high-frequency and strong-magnetism electricity stealing behavior. The chip comprises a controller, a power-down detector, an oscillator circuit, a reset circuit, a watchdog circuit, a pulse counter, a serial interface, a clock controller, a data storage unit, a high-frequency signal detecting module, a first filter, a strong-magnetism signal detecting module, a second filter and an AD converter. The controller is respectively connected with the power-down detector, the oscillator circuit, the reset circuit and the watchdog circuit and is connected with the pulse counter, the serial interface, the clock controller, the data storage unit and the AD converter through internal buses. According to the chip capable of recognizing the high-frequency and strong-magnetism electricity stealing behavior, an illegal criminal activity of an electricity thief can be recognized in time, an alarm can be given in time, an alarming signal can be sent in time so that investigation and treatment can be conducted by power grid staff, and therefore the power grid safety and the social safety are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric power anti-theft, and in particular relates to a chip capable of identifying high-frequency and strong magnetic electricity theft. Background technique [0002] In recent years, in addition to the basic characteristics of concealment, mobility, and suddenness, illegal and criminal acts of stealing electricity have also shown a trend of specialization, high technology, and trans-provincial migration, making investigation and punishment more and more difficult. Judging from the cases investigated and dealt with, some electricity-stealing households took special personnel on duty, installed monitoring and remote control equipment, prevented electricity inspectors from entering the scene, and quickly destroyed evidence of electricity-stealing scenes to prevent and prevent anti-stealing inspections, and even besieged and abused them. , Beating anti-stealing personnel, so the problems of anti-stealing ...

AI Technical Summary

Problems solved by technology

[0003] 1. When the electricity inspectors arrive at the suspected user’s metering device for inspection, criminals will remove the power-stealing equipment such as strong magnetism and high frequency in advance, making it difficult to find

[0004] 2. Even if the meter box is found to be damaged, due to the lack of strong evidence, the lawbreakers will not admit the fact of stealing electricity, resulting in the difficult situation of handling

[0005] 3. Power-stealing methods such as strong magnetism and high-frequency are currently in the blank area of ​​monitoring because it is difficult to find out the power consumption information collection system

Under the condition of strong interference, the metering chip cannot measure normally

[0009] The current smart meters all use smart metering chips. Whether it is a three-phase three-wire, three-phase four-wire smart meter, or a single-phase tiered price meter for residential users, they all face the same problem of interference.
