Description

A smart metering box based on edge computing to prevent electricity theft Technical Field

[0001] This invention belongs to the field of electricity metering technology, specifically a smart metering box based on edge computing to prevent electricity theft. Background Technology

[0002] With increasing electricity demand, electricity theft has become a serious problem, causing huge losses to power companies. While traditional smart metering boxes can transmit data remotely, their reliance on cloud platforms for data processing results in response delays and an inability to detect electricity theft in real time. Furthermore, network instability and insufficient data processing capabilities also contribute to their ineffectiveness in preventing electricity theft.

[0003] Edge computing is a technology that pushes data processing to the network edge, enabling real-time local data analysis, reducing latency, and improving system response speed. Compared to traditional smart meters, edge computing offers advantages such as low latency, local processing, and reduced reliance on the network. It can also immediately trigger an alarm when electricity theft occurs, ensuring the security of the power system.

[0004] However, current anti-electricity theft technologies still face problems such as poor real-time performance, high cost, and monitoring blind spots. Although remote monitoring and manual inspections can prevent electricity theft to some extent, they are difficult to respond in real time due to latency issues. At the same time, existing technologies often rely on complex network architectures, which increases the vulnerability of the system. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent metering box based on edge computing to prevent electricity theft, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent metering box for preventing electricity theft based on edge computing, comprising a base, a cabinet assembly fixedly installed on the top of the base, a cabinet door assembly fixedly installed on the front side of the cabinet assembly, and a computing component and a metering component installed on the inner side of the cabinet assembly, wherein the computing component is used to perform local analysis and processing on the electricity consumption data collected by the metering component, and to trigger an alarm and data reporting when abnormal electricity consumption behavior is detected;

[0007] The cabinet assembly includes an outer shell. A first baffle and a second baffle are movably snapped onto the back of the outer shell from left to right. Both the first baffle and the second baffle have round holes on their outer sides. Multiple sets of T-shaped strips are fixedly installed on the inner wall of the outer shell. There are two grooves on the front side of the outer shell. Two buzzers are installed on the top inner side of the outer shell. The first baffle, the second baffle, and the round holes are configured to facilitate the installation and maintenance of cables.

[0008] Preferably, the width of the first baffle is smaller than that of the second baffle, and the multiple sets of T-shaped strips are placed symmetrically on the left and right, and the distance between them in the vertical direction is set equally.

[0009] Preferably, the base has multiple elliptical grooves starting in the front-rear direction, and the multiple elliptical grooves are equally spaced.

[0010] Preferably, the cabinet door assembly includes a connecting block, which is fixedly installed on the outside of the outer shell. A hinge is inserted into the other side of the connecting block, and a door panel is fixedly connected to the other side of the hinge. An observation window is provided in the middle of the door panel, and an L-shaped block is installed on the front side of the door panel. A door status sensor is installed inside the L-shaped block. When the door panel is abnormally opened or destructively opened, a buzzer inside the cabinet assembly is triggered to sound an alarm.

[0011] Preferably, the computing component includes two first U-shaped strips, both of which are sleeved on the outer edge of the T-shaped strip. Each of the two first U-shaped strips has multiple first square holes starting from the middle position. A first fixing strip is inserted into any two sets of first square holes, and a computing unit is engaged with the outer edge of the first fixing strip.

[0012] Preferably, the metering component includes two second U-shaped strips, both of which are sleeved on the outer edge of the T-shaped strip. Each of the two second U-shaped strips has multiple second square holes starting from the middle position. A second fixing strip is inserted into any two sets of second square holes, and an electricity meter is snapped onto the outer edge of the second fixing strip.

[0013] Preferably, the computing unit is network-connected and has local computing capabilities. It analyzes the user's historical electricity consumption data through the electricity meter and forms an electricity consumption behavior model. When abnormal electricity consumption behavior that deviates from the electricity consumption behavior model is detected, the computing unit controls a buzzer to sound an alarm and reports the abnormal data to the network data center.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention sets up a computing unit with local computing capabilities in the smart meter box to perform edge computing analysis on user electricity consumption data and establish an electricity consumption behavior model. Abnormal electricity consumption behavior can be identified and judged locally, avoiding the latency problem caused by traditional cloud processing, and realizing rapid response and accurate alarm for electricity theft.

[0016] 2. This invention achieves real-time monitoring and on-site alarm for unauthorized opening of boxes through the linkage design of door status sensor and buzzer. At the same time, abnormal information can be reported to network data center simultaneously. This reduces the cost of manual inspection, lowers the system's dependence on complex network environment, and improves the overall security and stability of operation. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] As shown in Figures 1 to 7, this embodiment of the invention provides an intelligent metering box for preventing electricity theft based on edge computing, including a base 1. The base 1 is used to support and fix the entire metering box. Multiple elliptical grooves 11 are provided in the front-back direction of the base 1, and the multiple elliptical grooves 11 are equidistantly arranged for adjustment and fixation during the overall installation of the metering box, improving installation adaptability and stability.

[0027] A cabinet assembly 2 is fixedly installed on the top of the base 1. The cabinet assembly 2 is used to protect and centrally arrange the internal components. The cabinet assembly 2 includes an outer shell 21, which has a box-like structure. From left to right, a first baffle 22 and a second baffle 23 are respectively movably latched onto its back. Both the first baffle 22 and the second baffle 23 have round holes 24 on their outer sides. The first baffle 22, the second baffle 23, and the round holes 24 cooperate to form an inlet / outlet structure for cable entry, exit, and subsequent maintenance operations. By setting a detachable baffle structure, it is convenient for wiring and allows for inspection and maintenance without disassembling the entire cabinet.

[0028] The width of the first baffle 22 is smaller than that of the second baffle 23 to form a partitioned entry and exit structure, which can adapt to the cable laying requirements of different specifications or different uses and reduce the safety hazards caused by line crossing.

[0029] Multiple sets of T-shaped strips 25 are fixedly installed on the inner wall of the outer shell 21. The multiple sets of T-shaped strips 25 are arranged symmetrically on the left and right and are equidistant in the vertical direction. They are used to provide a modular installation base for the calculation component 4 and the metering component 5, which facilitates the flexible assembly and adjustment of different functional modules.

[0030] Two recesses 26 are provided on the front side of the outer casing 21 to facilitate the installation and opening / closing of the cabinet door assembly 3. Two buzzers 27 are installed on the top inner side of the outer casing 21, which are used to sound an alarm in abnormal conditions.

[0031] A cabinet door assembly 3 is fixedly installed on the front side of the cabinet assembly 2. The cabinet door assembly 3 includes a connecting block 31, which is fixedly installed on the outside of the outer shell 21. A hinge 32 is inserted into the other side of the connecting block 31, and a door panel 33 is fixedly connected to the other side of the hinge 32, so that the door panel 33 can rotate relative to the outer shell 21 to open or close.

[0032] An observation window 34 is provided in the middle of the door panel 33, which is used to view the internal metering status without opening the cabinet door. An L-shaped block 35 is installed on the front side of the door panel 33, and a door status sensor is installed inside the L-shaped block 35. When the door panel 33 is abnormally opened, illegally pried open, or destructively opened, the door status sensor sends an abnormal signal to the computing component 4. The computing component 4 controls the buzzer 27 to immediately sound an alarm, thereby realizing an immediate alarm for illegal door opening.

[0033] The inner side of the cabinet assembly 2 houses the calculation assembly 4 and the metering assembly 5. The calculation assembly 4 includes two first U-shaped strips 41, both of which are fitted onto the outer edge of the T-shaped strip 25 to achieve stable installation of the calculation assembly 4. Multiple first square holes 42 are formed in the middle of each of the two first U-shaped strips 41. A first fixing strip 43 is inserted into any two sets of first square holes 42, and a calculation unit 44 is engaged with the outer edge of the first fixing strip 43, thereby enabling detachable installation of the calculation unit 44.

[0034] The computing unit 44 is network-connected and has local computing capabilities, integrating a data processing module, a storage module, and a communication module. The computing unit 44 is electrically connected to the electricity meter 54 in the metering component 5 to acquire real-time user electricity consumption data.

[0035] The metering component 5 includes two second U-shaped strips 51, which are also sleeved on the outer edge of the T-shaped strip 25. Multiple second square holes 52 are formed in the middle of the two second U-shaped strips 51. A second fixing strip 53 is inserted into any two sets of second square holes 52. An electricity meter 54 is snapped onto the outer edge of the second fixing strip 53 for metering and collecting user electricity parameters.

[0036] In actual operation, the electricity meter 54 continuously collects user electricity consumption data and transmits it to the computing unit 44. The computing unit 44 analyzes user electricity consumption behavior and establishes an electricity consumption behavior model based on locally stored historical electricity consumption data. When the real-time collected electricity consumption data deviates from the electricity consumption behavior model, the computing unit 44 determines it as abnormal electricity consumption behavior.

[0037] Upon detecting abnormal power consumption, the computing unit 44 controls the buzzer 27 to sound an alarm, providing on-site alerts. Simultaneously, it reports the abnormal power consumption data and alarm information to the networked data center via the communication module, enabling remote monitoring and centralized management. By performing analysis and judgment locally through edge computing, response latency is significantly reduced, dependence on network stability is lessened, and the real-time performance and reliability of anti-theft power consumption are improved.

[0038] Working principle:

[0039] When the device is in operation, the electricity meter 54 in the metering component 5 continuously collects the user's electricity consumption parameters and transmits the collected electricity consumption data to the calculation unit 44 in the calculation component 4 in real time.

[0040] As a network edge computing unit with local computing capabilities, computing unit 44 compares and analyzes the acquired real-time electricity consumption data with its internally stored historical electricity consumption data to form a user electricity consumption behavior model. When the real-time electricity consumption data deviates from the electricity consumption behavior model, computing unit 44 determines it as abnormal electricity consumption behavior.

[0041] Upon detecting abnormal power consumption, the computing unit 44 immediately controls the buzzer 27 installed in the cabinet component 2 to sound an alarm, enabling real-time on-site alarm. At the same time, the abnormal power consumption data and alarm information are reported to the networked data center through the communication module, so that managers can remotely monitor and handle the situation.

[0042] In addition, when the door panel 33 in the cabinet door assembly 3 is opened abnormally or is opened in a destructive manner, the door status sensor set in the L-shaped block 35 triggers an alarm signal. After receiving the signal, the computing unit 44 controls the buzzer 27 to emit an alarm sound, thereby monitoring and protecting against unauthorized opening behavior in real time.

[0043] By performing electricity consumption data analysis and anomaly detection locally, this invention effectively reduces data processing latency, decreases reliance on external networks, and enables rapid response to electricity theft and unauthorized opening of electrical boxes.
