Chip capable of recognizing electrostatic interference electricity stealing behavior

Abstract

The invention discloses a chip capable of recognizing an electrostatic interference electricity stealing behavior. The chip capable of recognizing the electrostatic interference electricity stealing behavior 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, an electrostatic signal detecting module, a filter and an AD converter. The controller is a central processing unit of the chip, is respectively connected with the power-down detector, the oscillator circuit, the reset circuit and the watchdog circuit and is further 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 electrostatic interference electricity stealing behavior, an illegal criminal activity of an electricity thief can be recognized 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-stealing, and in particular relates to a chip capable of identifying static interference and stealing electricity. 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 inves...

Problems solved by technology

[0004] The current smart meters all use smart metering chips. Whether it is a three-phase three-wire smart meter, a three-phase four-wire smart meter, or a single-phase residential user's stepped electricity meter, they all face the same problem of being disturbed by static electricity. Some electricity stealers are Adopt the method of installing electrostatic interference devices near the meter to prevent the metering chip from working normally, thereby conducting electricity theft activities
