Description

Technical Field

[0001] This invention relates to the field of anti-electricity theft electrical equipment technology, and in particular to a remote anti-electricity theft device. Background Technology

[0002] Electricity metering boxes are the main equipment used by power companies to track electricity usage. Their safety and accuracy are crucial elements of electricity statistics. Electricity metering boxes mainly consist of combined current transformers (which collect three-phase current and voltage signals), the box itself, meters, surge arresters, vacuum circuit breakers (available in prepaid systems), etc. Current accuracy is 0.2S, and voltage accuracy is 0.2. The internal components may vary depending on the specific application. However, the meter (also called an electricity meter) is the primary working component, and electricity metering is now generally based on a one-meter-per-household principle.

[0003] Within certain user groups, there have been instances of electricity theft or the theft and resale of stolen meters.

[0004] Currently, many electrical devices, especially metering equipment before entering a home, are hotspots for electricity theft. To prevent thieves from opening the equipment enclosure, a simple sensor is installed at the door. When the door is opened, the sensor sends an electrical signal to the controller, which then activates other components, such as sounding an alarm or taking photos and videos. However, this method lacks concealment; the sensors are generally open-ended, making it easy for thieves to bypass them or prevent them from sending signals, thus rendering the anti-theft measures ineffective. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-electricity theft device to solve the problem that existing methods of electricity theft from power equipment are not concealed enough, and thieves can easily crack or bypass the sensors to prevent them from emitting electrical signals, resulting in an insignificant anti-electricity theft effect.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A remote anti-theft electricity device includes a meter box and an electricity meter. The meter box consists of a box body and a door hinged to one side of the box body. It also includes: An audio-visual acquisition device is installed at the top of the meter box and near the box door. The audio-visual acquisition range of the audio-visual acquisition device at least covers the electricity meter. Positioner installed inside the meter box; Voice playback device installed inside the meter box; Wireless transmission equipment installed inside the meter box; The controller, located inside the meter box, is used to coordinate the operation of the audio and video acquisition equipment, the locator, the voice playback equipment, and the wireless transmission equipment. An interlocking mechanism is installed between the enclosure and the door, which is used to lock the door and send an electrical signal to the controller. Methods to prevent electricity theft using remote anti-theft devices: When the cabinet door is closed, the interlocking mechanism controls the audio and video acquisition equipment, locator, voice playback equipment and wireless transmission equipment to be in standby or power-off non-working power-saving state through the controller; Use the key to open the interlocking mechanism. Turn it one full turn to release the interlocking mechanism from locking the door. The door will open, and the interlocking mechanism will send an electrical signal to the controller to control the audio and video acquisition equipment, the locator, the voice playback equipment, and the wireless transmission equipment to start working. This is the monitoring working state. Use the key to open the interlocking mechanism. Turn it two full turns to release the interlocking mechanism from locking the door. At this time, the interlocking mechanism will not send an electrical signal to the controller, which is the non-monitoring working state. The interlocking mechanism can be forcibly opened without a key. The interlocking mechanism will send an electrical signal to the controller, which will control the audio and video acquisition equipment, the locator, the voice playback equipment, and the wireless transmission equipment to start working. This is the monitoring working status.

[0007] A further technical solution is as follows: the interlocking mechanism includes a lock cylinder, a bolt, a locking rod, a sensor, a movable magnetic block, and a fixed magnetic block. The lock cylinder is rotatably installed inside the door. The bolt is positioned upwards and mounted on the lock cylinder via a torsion spring. The inner side of the box body is provided with a lock slot adapted to the bolt. The locking rod is positioned facing upwards and slidably installed inside the door, and the locking rod meshes with the outer peripheral teeth of the lock cylinder. The sensor is installed inside the door. The fixed magnetic block is installed inside the box body. The movable magnetic block and the fixed magnetic block attract each other, and the bottom of the movable magnetic block is provided with a sliding groove adapted to the locking rod. The sensing end of the sensor is adapted to the iron piece on the movable magnetic block, and the sensor is electrically connected to the controller.

[0008] A further technical solution is that the door is provided with a trapezoidal notch that matches the movable magnetic block.

[0009] A further technical solution is that the sensor is a proximity sensor.

[0010] A further technical solution is that the lock cylinder rotates two full rotations to unlock, the distance between the top of the locking rod and the opening of the slide groove is greater than the circumference of the lock cylinder, and the distance between the top of the locking rod and the bottom of the slide groove is less than twice the circumference of the lock cylinder.

[0011] A further technical solution is that the meter box is equipped with an independent power supply that supplies power to the audio and video acquisition equipment, the locator, the voice playback equipment, the wireless transmission equipment, and the controller.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This invention proposes an anti-electricity theft device. The anti-electricity theft mechanism is achieved through an interlocking mechanism. This interlocking mechanism not only locks the door but also sends an electrical signal to the controller. The interlocking mechanism controls the anti-electricity theft device's operation differently depending on the way the door is opened. Forcibly opening the door (such as breaking or prying it open) or using theft tools to open the interlocking mechanism will trigger the monitoring system to warn against theft or other illegal activities. It can even record relevant evidence when necessary. In particular, the interlocking mechanism is sufficiently concealed, and its operation is highly secure, making it difficult for thieves to bypass or circumvent the interlocking mechanism to steal electricity.

[0024] Example 1: This implementation example Figure 1 , Figure 2 and Figure 3 As shown, a remote anti-theft electricity device includes a meter box 1 and an electricity meter 2. The meter box 1 consists of a box body 11 and a door 12 hinged to one side of the box body 11, and also includes: The audio-visual acquisition device 4 is installed at the top of the meter box 1 and near the door 12. The audio-visual acquisition range of the audio-visual acquisition device 4 covers at least the electricity meter 2. Positioner 5 is installed inside meter box 1; Voice playback device 6 installed inside meter box 1; Wireless transmission device 7 installed inside meter box 1; The controller 8 is installed in the meter box 1. The controller 8 is used to control the audio and video acquisition device 4, the locator 5, the voice playback device 6 and the wireless transmission device 7 to work in coordination. The interlocking mechanism 9 is provided between the housing 11 and the door 12. The interlocking mechanism 9 is used to lock the door 12 and send an electrical signal to the controller 8. Methods to prevent electricity theft using remote anti-theft devices: When the door 12 is closed, the interlocking mechanism 9 controls the audio and video acquisition device 4, the locator 5, the voice playback device 6 and the wireless transmission device 7 to be in standby or power-off non-working power-saving state through the controller 8; Use the key to open the interlocking mechanism 9, turn it one full turn to release the interlocking mechanism 9 from locking the cabinet door 12, and the cabinet door 12 will open. At this time, the interlocking mechanism 9 will send an electrical signal to the controller 8 to control the audio and video acquisition device 4, the locator 5, the voice playback device 6 and the wireless transmission device 7 to start working. This is the monitoring working state. Use the key to open the interlocking mechanism 9, turn it two full turns to release the interlocking mechanism 9 from locking the door 12. At this time, the interlocking mechanism 9 will not send an electrical signal to the controller 8, which is the non-monitoring working state. The interlocking mechanism 9 is opened by force without a key. The interlocking mechanism 9 will send an electrical signal to the controller 8, which will control the audio and video acquisition device 4, the locator 5, the voice playback device 6 and the wireless transmission device 7 to start working. This is the monitoring working state.

[0025] The working principle of this embodiment is as follows: Under normal circumstances, the cabinet door 12 is locked to the cabinet body 11 through the interlocking mechanism 9. The interlocking mechanism 9 controls the audio-visual acquisition device 4, the locator 5, the voice playback device 6, and the wireless transmission device 7 to be in standby or power-off non-working power-saving state through the controller 8. This is the normal situation. When thieves or other non-workers are unaware of the structure and usage of the interlocking mechanism 9, they forcibly open the interlocking mechanism 9 without a key. The interlocking mechanism 9 will send an electrical signal to the controller 8 to control the audio-visual acquisition device 4, the locator 5, the voice playback device 6, and the wireless transmission device 7 to start working. This is the monitoring working state. When the interlocking mechanism 9 is opened using a key (e.g., by stealing or finding a key), turning it one full turn releases the interlocking mechanism 9 and unlocks the cabinet door 12. Although the cabinet door 12 is open, the interlocking mechanism 9 sends an electrical signal to the controller 8, controlling the audio-visual acquisition device 4, the locator 5, the voice playback device 6, and the wireless transmission device 7 to start working; this is the monitoring working state. Only by turning it two full turns can the interlocking mechanism 9 be released and the cabinet door 12 unlocked. At this time, the interlocking mechanism 9 will not send an electrical signal to the controller 8; this is the non-monitoring working state. This greatly improves the concealment and security of the anti-theft electricity measures.

[0026] The audio and video acquisition device 4, which monitors the working status, collects audio and video of the corresponding behavior and can upload it to the monitoring backend through the wireless transmission device 7; the locator 5 and the controller 8 emit positioning signals and can upload them to the monitoring backend through the wireless transmission device 7; the voice playback device 6 can play pre-stored reminder or alarm audio and can also make manual announcements through the wireless transmission device 7.

[0027] Example 2: Based on the above embodiments, this embodiment shows that the interlocking mechanism 9 includes a lock cylinder 10, a lock tongue 13, a lock rod 14, a sensor 15, a movable magnetic block 16, and a fixed magnetic block 17. The lock cylinder 10 is rotatably installed inside the door 12. The lock tongue 13 is arranged facing upward and is installed on the lock cylinder 10 by a torsion spring. The inner side of the box body 11 is provided with a lock opening 18 that matches the lock tongue 13. The lock rod 14 is arranged facing upward and is slidably installed inside the door 12. The lock rod 14 meshes with the outer peripheral teeth of the lock cylinder 10. The sensor 15 is installed inside the door 12. The fixed magnetic block 17 is installed inside the box body 11. The movable magnetic block 16 and the fixed magnetic block 17 attract each other. The bottom of the movable magnetic block 16 is provided with a sliding groove 19 that matches the lock rod 14. The sensing end of the sensor 15 matches the iron piece on the movable magnetic block 16. The sensor 15 is electrically connected to the controller 8.

[0028] When unlocking with a key compatible with lock cylinder 10, turn it at a certain angle (e.g.) Figure 3(When the lock cylinder 10 is rotated to the left at a suitable angle), the latch 13 leaves the lock opening 18 and is abutted against the inner wall of the door 12. However, the lock cylinder 10 can still rotate to the left (due to the presence of the torsion spring), and the door 12 can be opened at this time. However, when opening the door 12, because the rotation angle of the lock cylinder 10 is insufficient, the locking rod 14 has not yet entered the slide groove 19 at the bottom of the movable magnetic block 16. The movable magnetic block 16 is attracted to the fixed magnetic block 17. The sensor 15 inside the door 12 separates from the movable magnetic block 16 and sends a signal to release the interlocking mechanism 9 from locking the door 12. The door 12 opens. At this time, the interlocking mechanism 9 sends an electrical signal to the controller 8 to control the audio and video acquisition device 4, the locator 5, the voice playback device 6, and the wireless transmission device 7 to start working. This is the monitoring working state. Continue to rotate the lock cylinder 10, and the locking rod 14 enters the slide groove 19 at the bottom of the movable magnetic block 16. When the door is opened, the movable magnetic block 16 is hooked by the locking rod 14, overcoming the attraction of the fixed magnetic block 17, and the door 12 opens. The sensor 15 inside, together with the movable magnetic block 16, does not send a signal to release the interlocking mechanism 9 from locking the door 12. At this time, the interlocking mechanism 9 will not send an electrical signal to the controller 8, which is a non-monitoring working state.

[0029] It is worth noting that when the door is pried open, the movable magnetic block 16 is attracted to the fixed magnetic block 17, and the sensor 15 inside the door 12 separates from the movable magnetic block 16 and sends a signal.

[0030] Preferably, the door 12 is provided with a trapezoidal notch 20 that is adapted to the movable magnetic block 16.

[0031] The trapezoidal notch 20 is used for positioning the movable magnetic block 16, which facilitates the engagement of the locking rod 14 with the sliding groove 19 at the bottom of the movable magnetic block 16.

[0032] Preferably, sensor 15 is a proximity sensor.

[0033] Preferably, the number of unlocking rotations of the lock cylinder 10 is two revolutions, the distance between the top of the lock rod 14 and the opening of the slide groove 19 is greater than the circumference of the lock cylinder 10, and the distance between the top of the lock rod 14 and the bottom of the slide groove 19 is less than twice the circumference of the lock cylinder 10.

[0034] Preferably, the meter box 1 is equipped with an independent power supply 3 that supplies power to the audio and video acquisition device 4, the locator 5, the voice playback device 6, the wireless transmission device 7, and the controller 8.

[0035] Independent power supply 3 is for emergency use, such as in the event of an accidental or intentional power outage to the remote anti-theft device. Under normal circumstances, independent power supply 3 does not participate in power supply. When independent power supply 3 is low on power, the remote anti-theft device will charge it.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
