Detailed description of the invention
Below in conjunction with accompanying drawing and by specific embodiment, the present invention will be described in detail, and following example are explanation of the invention, and the invention is not limited in implementation below.
As it is shown in figure 1, electric power electric energy anti-theft apparatus for electricity meter box provided by the invention, including controller 1, the fraudulent use detection device electrically connected with controller 1, video monitoring device 7, communication module 6, electrical energy changer 4.
Fraudulent use detection device, for detecting whether there is electricity filching behavior to occur, and is sent to controller 1 by stealing signal.Generally, easily there is electricity filching behavior at positions such as ammeter case lid, lead sealing, gauge table wiring place, as ammeter box be opened, lead sealing is destroyed or gauge table wiring is changed, when any of which condition meets, even if namely should prevent electricity theft prevention.Therefore, in the present embodiment, fraudulent use detection device includes for detecting ammeter case lid detecting device 2 that whether ammeter box artificially opened, for detecting lead sealing detecting device 3 that whether lead sealing be destroyed and/or for detecting the gauge table wiring testing device 5 whether gauge table wiring is changed.
Above-mentioned ammeter case lid detecting device 2 adopts pyroelectric infrared sensor, and when ammeter case lid is artificially opened, pyroelectric infrared sensor detects variations in temperature, and this stealing signal sends to controller 1 and triggers warning and video recording.
Above-mentioned lead sealing detecting device 3 and gauge table wiring testing device 5 all adopt vibration switch, lead sealing and gauge table wiring are installed vibration switch, when lead sealing is destroyed or triggers vibration switch during gauge table wiring campaign, so that stealing signal is sent to controller 1 and triggers warning and record a video by vibration switch.
Video monitoring device 7, is used for recording scene around ammeter box, and stores video image, to record electricity filching behavior.Video detecting device adopts infrared video camera, use 360 little water droplet intelligent cameras in the present embodiment, 9 940nm are without red exposure infrared lamp, maximum night vision scope reaches 7 meters, 110 degree of visual angle, diagonal angle, advanced HYBRID algorithm makes day and night scene switch freely, accurately presents, maximum support 128G storage card, stores video image.This video detecting device of visible employing, monitoring range is big, and day and night scene switches freely, and internal memory is big, can effectively record and store electricity filching behavior, it is provided that vaild evidence, to stealing molecule with effective fright.
Controller 1, controls video monitoring device 7 according to the stealing signal received and works, and send alarm signal by communication module 6, and alarm signal can be a stealing alarming short message, is sent to designated mobile phone;Alarm signal can also be sent to host computer, real-time display alarm information by controller 1, checks for staff.Controller 1 with STM32F series monolithic for core, fast operation, have sleep, shutdown, the multiple low power mode of operation such as standby;The highest 72MHz operating frequency, fast operation;The Flash memory space of maximum 256Kb;Low cost, high reliability.
Communication module 6 adopts the SIMs such as technical grade wireless GPRS module, signal stabilization, suitable for movable, linkage, telecommunications, to low cost, can send alarm signal in time, improve warning efficiency.
Electrical energy changer 4, for alternating current is changed into the power supply needed for this anti-electricity-theft device, powers to anti-electricity-theft device.In the present embodiment, electrical energy changer 4 utilizes the alternating current 220V of gauge table to input, and by links such as isolation, overcurrent protection, rectification, filtering, obtains 5V power supply, powers to other functional units in anti-electricity-theft device.
The operation principle of this anti-electricity-theft device is: ammeter case lid detecting device 2, lead sealing detecting device 3 and gauge table wiring testing device 5 have detected whether electricity filching behavior, and the stealing signal detected is sent to controller 1, once above-mentioned detection device any one stealing signal detected, namely controller 1 starts video monitoring device 7 and records a video, and generate a stealing alarm message, being dealt into designated mobile phone, staff can arrive in the very nick of time after receiving note field verification situation, contains electricity filching behavior in time.
Disclosed above it is only the preferred embodiment of the present invention; but the present invention is not limited to this; what any those skilled in the art can think does not have creationary change and the some improvements and modifications made without departing from the principles of the present invention, all should be within the scope of the present invention.
