Remote electricity larceny prevention alarm system for distribution box

Abstract

The invention discloses a remote electricity larceny prevention alarm system for a distribution box. The remote electricity larceny prevention alarm system comprises a distribution metering box, a key disk, a main controller, an unpacking detection module, an alarm module, a GSM (Global System for Mobile Communications) short message module, a power supply module, a filter module, a network alarm receiving center and a mobile short message gateway, and is characterized by further comprising a power outage detection module, a key identification module, an anti-control power failure module, a stroke switch monitoring module and an audio monitoring module, wherein the unpacking detection module, the alarm module, the GSM short message module, the power outage detection module, the key identification module, the anti-control power failure module and the audio monitoring module are connected with the main controller, and the GSM short message module realizes the alarm and control to the network alarm receiving center through the mobile short message gateway; the power supply module is processed by the filter module and then supplies power to each module. The remote electricity larceny prevention alarm system provided by the invention is reasonable in design, and can only be opened by the specially authorized key disk, otherwise the system can report an illegal opening alarm to the center, so that the electricity larceny phenomena is effectively prevented.

Description

technical field [0001] The invention relates to the field of anti-stealing power of distribution boxes, in particular to a remote anti-stealing alarm system for distribution boxes. Background technique [0002] With the gradual completion of the project of one meter per household for urban residents, the phenomenon of electricity theft by residents and villagers has gradually emerged, and the proportion of electricity theft among individual industrial and commercial households and private enterprises has gradually increased. At present, according to the characteristics of electricity theft, it is mainly divided into three types of theft: [0003] 1. Technical electricity theft, currently mainly includes: First, some electricity users have a little knowledge of electricity knowledge and technology. Or the two-phase incoming and outgoing lines are connected in reverse or not connected according to the correct phase sequence to achieve the purpose of stealing electricity; secon...

[0005] 2. Extensive stealing of electricity. At present, projects such as pumping water and building houses in rural areas are on the rise. In order to facilitate stealing electricity, many temporary users take nearby measures without the approval of the power company, and directly use wire hooks on the power line to pump water. The user’s motor insulation is unqualified, causing the grounding to often cause tripping in the station area, which seriously interferes with the order of power consumption. Because the building user needs to use three-phase power, some of the power-stealing lines are several kilometers long, with many exposed joints, and no one is watching. , poses a great threat to production safety

[0006] 3. Concealed electricity theft. This kind of users use the household wire behind the switchboard or in front of the electric meter to secretly connect the electric load. Walls or other coverings bury lines indoors, use switch blades to control electricity stealing, and some even use telephone lines and TV lines to steal electricity, which lays a bane for safe production and makes it difficult for ordinary people to find out their electricity theft Behavior
