Description

Technical Field

[0001] The present invention relates to the technical field of smart electric meters, and in particular to an electric meter control method with an automatic reclosing circuit breaker. Background Art

[0002] In the context of the rapid development of smart grid and smart meter technology, the performance of the external circuit breaker of the meter, as a key component of the smart fee control system, directly affects the user's electricity experience and the efficiency of grid management. At present, there are many design solutions for meter circuit breakers on the market, which meet the needs of smart meters to varying degrees, but there are also some problems that need to be solved.

[0003] The Chinese patent with the patent publication number CN104201016B discloses a circuit breaker for prepaid electricity meters with an automatic reclosing function. The circuit breaker detects the control voltage signal of the prepaid electricity meter through the control circuit to realize the power-off and automatic reclosing functions for arrears. Although the patent has some innovations in circuit design and control logic, it does not provide a specific solution for how to realize the automatic operation of the external circuit breaker of the electricity meter, especially how to realize efficient automatic reclosing through a mechanical structure.

[0004] The Chinese patent with the patent publication number CN107799331A discloses an operating mechanism and control method of an external circuit breaker of an electric meter, and adopts a connecting rod transmission technology to realize the operation of the external circuit breaker of the electric meter. The patent drives the worm to rotate through the motor in the operating box, and the worm drives the worm wheel to rotate. The driving member on the worm wheel further drives the guide member to move, and finally realizes the opening and closing actions of the circuit breaker through the linkage of the guide member, the inner shaft and the circuit breaker handle. Although this scheme realizes the automatic control of the circuit breaker and improves the convenience of operation. However, this scheme adopts a connecting rod transmission mechanism to switch the closing, opening and tripping self-protection functions, which has obvious deficiencies in transmission efficiency and reliability. By adopting a connecting rod transmission mechanism to switch the closing, opening and tripping self-protection functions, the meshing of the worm wheel and the toothless gear and the transmission of the connecting rod during the transmission process will generate large friction and energy loss, resulting in reduced transmission efficiency. In addition, under long-term use, components such as the worm wheel, toothless gear and connecting rod are prone to wear, which is easy to cause mechanical failures and affect the reliability and service life of the circuit breaker.

[0005] In addition, in the existing technology, the closing and opening of the meter usually rely on manual operation, which is prone to operational errors and thus causes safety hazards. At the same time, the meter also lacks real-time monitoring and automatic response mechanisms, and cannot handle abnormal meter status in a timely manner, which may lead to a decrease in the safety and reliability of the power system.

[0006] With the development of smart grids, higher requirements are placed on the intelligence and integration level of electric meters. The existing electric meter closing and circuit breaker design still has many deficiencies in transmission efficiency, reliability, intelligence and integration. How to realize the automatic operation of the electric meter closing and circuit breaker, especially how to realize efficient and reliable automatic reclosing function through mechanical structure, is still a technical problem to be solved in this field. Summary of the invention

[0007] In view of this, the present invention proposes a method for controlling an electric meter with an automatic reclosing circuit breaker, aiming to solve the problem of manual intervention requirements and potential safety hazards in the closing and opening operations of traditional electric meters. This application realizes the automatic control of the electric meter by integrating the automatic closing and circuit breaker with the intelligent terminal, and can automatically close and open the circuit according to the user's fee situation, reducing human intervention; at the same time, by real-time monitoring of the electric meter status, timely issuing early warning notifications, ensuring circuit safety, avoiding potential dangers caused by misoperation or abnormal conditions, thereby improving the efficiency and safety of power management.

[0008] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0009] A method for controlling an electric meter with an automatic reclosing circuit breaker comprises the following steps:

[0010] S1: The barcode and MAC address of the electric meter are obtained from the database of the power company using the smart terminal, but are not stored in the smart terminal;

[0011] S2: Pair and connect the electric meter with the smart terminal to perform initial configuration;

[0012] S3: The smart terminal monitors the status of the electric meter in real time and sends an early warning notification to the smart terminal when the electric meter status is abnormal;

[0013] S4: The intelligent terminal sends a signal to the control chip in the operation box, and the control chip in the operation box performs closing and opening operations after analysis.

[0014] Furthermore, in step S1, before requesting to obtain the meter barcode and MAC address, the smart terminal uses username and password verification, digital certificate verification or biometric recognition to authenticate the identity. After the verification is passed, only the meter barcode and MAC address corresponding to its identity can be obtained and saved in the smart terminal.

[0015] Furthermore, in step S2, the following steps are included:

[0016] S21: The smart terminal sends a pairing request to the electric meter through a Bluetooth pairing function or a secret key pairing function according to the obtained barcode and MAC address information;

[0017] S22: After the pairing is successful, the smart terminal sends an initialization instruction to the electric meter, including setting the basic parameters, communication protocol, and data format of the electric meter. After receiving the above initialization instruction, the electric meter performs configuration according to the instruction and feeds back the configuration result to the smart terminal;

[0018] S23: After confirming that the meter configuration is correct, the smart terminal saves the configuration information and ends the initialization process.

[0019] Furthermore, in step S3, the following steps are included:

[0020] S31: The intelligent terminal is connected to the electric meter through communication, and can obtain the current, voltage, power and cost information of the electric meter in real time;

[0021] S32: The smart terminal has a built-in data processing module, which performs real-time analysis on the collected meter data to determine whether the meter is in a normal working state. If so, the process returns to S31; if not, the process proceeds to S33;

[0022] S33: The smart terminal sends a warning notification to the user through any one of text messages, APP push, voice messages, and phone calls.

[0023] Furthermore, in step S31, the smart terminal communicates with the electric meter to establish a communication connection through a communication protocol or a communication interface, and the electric meter sends the current, voltage, power and cost information of the electric meter to the smart terminal every 1 second or every preset time.

[0024] Furthermore, the preset interval time for the electric meter to send the electric meter status information to the smart terminal ranges from 3s to 20s.

[0025] Furthermore, in step S32, by presetting the normal working range thresholds of the current, voltage, power and cost information in the data processing module of the smart terminal, when the collected values ​​of the current, voltage, power and cost information obtained by the smart terminal are outside the normal working range thresholds, it is judged that the meter state is abnormal.

[0026] Further, in step S4, if the smart terminal sends an alarm notification of abnormal meter status within the preset time T 1 After that, the smart terminal sends a trip signal to the control chip without any authorized operation. If the smart terminal sends an abnormal warning notification of the meter status within the preset time T 1 Within the preset time T, the smart terminal obtains the authorization operation to keep the switch in the closed state. 2 No more warning notifications will be sent.

[0027] Further, in step S4, if the smart terminal3 If the meter sends an opening signal and a closing signal for the same abnormal state, and the opening signal is greater than the closing signal, then the smart terminal will issue an abnormal warning within the preset time T 2 No more warning notifications will be sent.

[0028] Furthermore, the preset time T 1 The value range is 0.5min~10min, and the preset time T 2 The value range is 12h~24h, and the preset time T 3 The value range is 30min~180min.

[0029] Compared with the prior art, the electric meter control method with automatic reclosing circuit breaker device of the present invention has the following advantages:

[0030] (1) The electric meter control method with automatic reclosing circuit breaker device described in the present invention realizes the function of real-time monitoring of the electric meter status by introducing a pairing connection between an intelligent terminal and the electric meter, and can promptly detect abnormal situations and send early warning notifications to users, which not only improves the automation level of the power system, but also reduces the need for manual intervention and reduces operating costs. At the same time, the intelligent terminal can judge the working status of the electric meter based on real-time data analysis, and thus quickly send a trip signal under abnormal circumstances, ensuring circuit safety and preventing the occurrence of potential dangers, further improving user experience and system reliability.

[0031] (2) The electric meter control method with automatic reclosing circuit breaker device described in the present invention realizes comprehensive control and rapid response to the status of the electric meter through real-time monitoring, intelligent control, optimized pairing connection and early warning mechanism of the intelligent terminal, ensures the safe and stable operation of the power system, improves the operation and maintenance efficiency and management level, provides strong support for the intelligent and automated development of the power system, and also brings users a more convenient and efficient power use experience.

[0046] Example 1

[0047] like Figures 1 to 6 As shown, the present application discloses an electric meter with an automatic closing and circuit breaker device, comprising:

[0048] The external handle device 100 includes a handle connecting rod 2, one end of which can rotate along a first rotating shaft 3 on an operating box 1, and an operating rod 4 is arranged at the other end of the handle connecting rod 2. The operating rod 4 passes through a first sliding groove 5 on the operating box 1 and extends into the inside of the operating box 1 to be connected to the circuit breaker handle. When the handle connecting rod 2 rotates, it can drive the circuit breaker handle to switch between closing and opening positions.

[0049] The tripping protection device 200 includes a second connecting rod 8, one end of which can rotate along a second rotating shaft 9 on the operating box 1, and an external lever 6 is arranged at the other end of the second connecting rod 8. The external lever 6 passes through a second sliding groove 7 on the operating box 1 and cooperates with a circuit breaker linkage structure inside the operating box 1 to realize that the circuit breaker handle is disengaged from the closing safety lock in the closing position;

[0050] The driving device 300 includes a first driving motor 11 and a transmission rack device 14, wherein the transmission rack device 14 is hingedly fixed to the operation box 1 through a fifth rotating shaft 29, and the first driving motor 11 can drive the transmission rack device 14 to rotate. A first driving rod 15 and a second driving rod 16 are arranged on the transmission rack device 14, and the first driving rod 15 and the second driving rod 16 are arranged on the transmission rack device 14 through a rotating shaft and a torsion spring;

[0051] The switching device 400 includes a second drive motor 17 and a sliding limiter 21, wherein the second drive motor 17 can push the sliding limiter 21 to move from an upper position to a lower position, and push the second drive rod 16 to rotate toward a side away from the first rotating shaft 3;

[0052] The first rotating shaft 3, the second rotating shaft 9, and the fifth rotating shaft 29 are provided with reset torsion springs for self-reset of the handle connecting rod 2, the second connecting rod 8, and the transmission rack device 14 in a power-loss state;

[0053] The sliding limiter 21 in the switching device 400 is in the upper position, and the second driving rod 16 can push the handle connecting rod 2 to drive the operating rod 4 to move from the closing position to the opening position under the rotation of the transmission rack device 14. At this time, the first driving rod 15 is always in a disengaged state from the second connecting rod 8 during the rotation process with the transmission rack device 14;

[0054] The sliding limiter 21 in the switching device 400 moves to the lower position, the second driving rod 16 rotates to the side away from the first rotating shaft 3, and the first driving rod 15 correspondingly rotates toward the pushing part of the second connecting rod 8. When the transmission rack device 14 is driven to rotate by the first driving motor 11, the first driving rod 15 can drive the second connecting rod 8 to drive the external lever 6 to rotate, so that the circuit breaker handle is disengaged from the closing safety lock in the closing position. At this time, the second driving rod 16 is always in a disengaged state from the handle connecting rod 2 during the rotation process with the transmission rack device 14.

[0055] The present application discloses an electric meter with an automatic closing circuit breaker device, which realizes automatic closing and opening control of the electric meter by integrating an external handle device 100, a tripping protection device 200, a driving device 300 and a switching device 400. When the user's fee is small and a trip reminder is required, the electric meter needs to be opened, the sliding limiter 21 in the switching device 400 is in the upper position, the first driving motor 11 in the driving device 300 is started, driving the transmission rack device 14 to rotate, and the second driving rod 16 on the transmission rack device 14 rotates accordingly, pushing the handle connecting rod 2 in the external handle device 100, so that the operating rod 4 moves, and then drives the circuit breaker handle inside the electric meter to switch from the closing position to the opening position. At this time, the first driving rod 15 on the transmission rack device 14 remains disengaged from the second connecting rod 8 of the tripping protection device 200, and the second connecting rod 8 is always in the original position, which does not affect the opening operation; after the tripping reminder, the electric meter needs to be closed, and at this time, the first driving motor 11 in the driving device 300 rotates in the opposite direction, and the handle connecting rod 2 is reset under the action of the self-resetting torsion spring and drives the operating rod 4 and the circuit breaker handle inside the electric meter to switch from the opening position to the closing position; when the electric meter is opened due to arrears, the second driving motor 17 of the switching device 400 is started, pushing the sliding limiter 21 downward The first drive rod 15 is moved so that the second drive rod 16 rotates in the direction away from the first rotating shaft 3 where the handle connecting rod 2 rotates. At the same time, the first drive rod 15 rotates under the action of the torsion spring at its own rotating shaft and rotates to a position close to the pushing portion on the second connecting rod 8. The first drive motor 11 is started and the transmission rack device 14 rotates. At this time, the first drive rod 15 pushes the second connecting rod 8, and cooperates with the circuit breaker linkage structure through the external lever 6, so that the circuit breaker handle is disengaged from the closing safety lock in the closing position. This action is implemented by the cooperation of the energy storage spring mechanism and the safety lock mechanism. This part of the structure belongs to the prior art in this field and will not be described in detail here. At this time, the meter is in the tripping protection state, and then the arrears tripping operation is completed, and the second drive rod 16 remains separated from the handle connecting rod 2 during this process, which does not affect the arrears tripping operation; after the user renews the fee, the first drive rod 15 rotates in the opposite direction, and the second connecting rod 8 is reset under the action of the self-resetting torsion spring and drives the outer lever 6 to be separated from the circuit breaker linkage structure, and the tripping protection state of the meter is invalid. The handle connecting rod 2 is reset under the action of the self-resetting torsion spring and drives the operating rod 4 and the circuit breaker handle inside the meter to switch from the open position to the closed position. The second drive motor 17 of the switching device 400 drives the sliding limiter 21 to move to the upper position, and the second drive rod 16 is reset and drives the first drive rod 15 to rotate to a position away from the push part on the second connecting rod 8, and the meter returns to the initial state. During the whole process, the reset torsion springs on each rotating shaft ensure that the device can automatically reset in the power-losing state.

[0056] The electric meter with automatic closing and circuit breaker device described in the present application realizes the automatic closing and opening functions of the electric meter through a clever mechanical structure design. On the one hand, the electric meter can automatically close and open the circuit according to the user's fee situation without manual intervention, thereby improving the convenience and efficiency of electricity management. On the other hand, through the design of the trip protection device 200, even if the circuit breaker handle inside the electric meter is mistakenly operated to the closing position, the circuit breaker handle can be disengaged from the closing safety lock at the closing position through the cooperation of the external lever 6 and the circuit breaker linkage structure, effectively preventing the hidden danger of electricity safety caused by misoperation.

[0057] As a preferred example of the present application, one end of the first driving rod 15 is hingedly fixed to the transmission rack device 14 through a third rotating shaft 25, a torsion spring for self-resetting the first driving rod 15 is arranged at the third rotating shaft 25, and a first limiting rod 26 is arranged near the middle of the first driving rod 15; the middle part of the second driving rod 16 is hingedly fixed to the transmission rack device 14 through a fourth rotating shaft 27, a torsion spring for self-resetting the second driving rod 16 is arranged at the fourth rotating shaft 27, and a first limiting portion 1601 is arranged at one end of the second driving rod 16, and the first limiting portion 1601 can push on the first limiting rod 26 to prevent the first driving rod 15 from self-resetting. In the present application, when the sliding limiter 21 of the switching device 400 is in the upper position, the second drive rod 16 is hingedly fixed to the transmission rack device 14 by the torsion spring and the fourth rotating shaft 27, and the first limiter 1601 of the second drive rod 16 pushes the first limiter 26 on the first drive rod 15 and moves the pushing end of the first drive rod 15 away from the pushing part on the second connecting rod 8, so that when the transmission rack device 14 is driven to rotate by the first drive motor 11, only the second drive rod 16 is pushed against the handle connecting rod 2 when it rotates integrally with the transmission rack device 14, and the first drive rod 15 is disengaged from the second connecting rod 8 when it rotates integrally with the transmission rack device 14; when the sliding limiter 21 of the switching device 400 is in the upper position, the second drive rod 16 is hingedly fixed to the transmission rack device 14 by the torsion spring and the fourth rotating shaft 27, and the first limiter 1601 of the second drive rod 16 pushes the first limiter 26 on the first drive rod 15 and moves the pushing end of the first drive rod 15 away from the pushing part on the second connecting rod 8, so that when the transmission rack device 14 is driven to rotate by the first drive motor 11, only the second drive rod 16 is pushed against the handle connecting rod 2 when it rotates integrally with the transmission rack device 14, and the first drive rod 15 is disengaged from the second connecting rod 8 when it rotates integrally with the transmission rack device 14. When the limiter 21 is in the lower position, the second drive rod 16 is pushed by the sliding limiter 21 to rotate in the direction away from the first rotation axis 3 where the handle link 2 rotates. At this time, the first limiter 1601 of the second drive rod 16 pushes the first limiter 26 on the first drive rod 15 to disengage, and the first drive rod 15 moves to the pushing portion close to the second link 8 under the action of the torsion spring at the third rotation axis 25, so that when the transmission rack device 14 is driven to rotate by the first drive motor 11, only the first drive rod 15 pushes the second link 8 when rotating with the transmission rack device 14, and the second drive rod 16 disengages from the handle link 2 when rotating with the transmission rack device 14. Preferably, the first limiter 1601 is designed in an arc or bent shape.

[0058] This design achieves flexible switching of the driving rod's working state through simple mechanical linkage, ensuring accurate control of the meter in different scenarios. Even in the event of a sudden power outage or fault, it can ensure that the device quickly returns to its initial state, improving the stability and safety of the system.

[0059] As a preferred example of the present application, a second limit rod 28 is provided on the side of the second drive rod 16 away from the first limit portion 1601, and the second limit rod 28 can be pushed by the sliding limit member 21 when the second drive rod 16 is driven from the upper position to the lower position and drive the second drive rod 16 to rotate along the fourth rotation axis 27.

[0060] Through the above-mentioned optimized design, a second limit rod 28 is added to the second driving rod 16, and a direct mechanical linkage is formed with the sliding limit member 21, which simplifies the mechanical structure, reduces energy loss and mechanical wear, greatly improves the response speed and action accuracy of the electric meter drive device, and improves the operating efficiency and reliability of the device.

[0061] As a preferred example of the present application, a first worm 12 is provided on the first driving motor 11 , and the first worm 12 drives the transmission rack device 14 to rotate through the first transmission device 13 . As a preferred example, the first transmission device 13 includes a first transmission gear assembly 23 and a second transmission gear assembly 24, the first transmission gear assembly 23 is a double gear, namely a first gear portion 2301 and a second gear portion 2302, the first gear portion 2301 and the second gear portion 2302 are coaxially arranged, and the tooth diameter ratio of the first gear portion 2301 to the second gear portion 2302 is greater than 1.5; the second transmission gear assembly 24 has double gears, namely a third gear portion 2401 and a fourth gear portion 2402, the third gear portion 2401 and the fourth gear portion 2402 are coaxially arranged, and the tooth diameter ratio of the third gear portion 2401 to the fourth gear portion 2402 is greater than 1.5; the first worm 12 is meshed with the first gear portion 2301 of the first transmission gear assembly 23, the second gear portion 2302 is meshed with the third gear portion 2401, and the fourth gear portion 2402 is meshed with the transmission rack device 14 for transmission. Preferably, the rack of the transmission rack device 14 is a fan-shaped rack.

[0062] This arrangement realizes efficient transmission and conversion of the power of the first drive motor 11 by introducing a gear transmission structure. Specifically, the first drive motor 11 drives the first worm 12 to rotate, and the first worm 12 meshes with the first gear portion 2301 of the first transmission gear assembly 23 to transmit the rotational force to the first transmission gear assembly 23; the first transmission gear assembly 23 is designed as a double gear, including a first gear portion 2301 and a second gear portion 2302 with a tooth diameter ratio greater than 1.5, and this design realizes the first deceleration and torque increase in the power transmission process; subsequently, the second gear portion 2302 meshes with the third gear portion 2401 of the second transmission gear assembly 24, and the second transmission gear assembly 24 is also a double gear structure, including a third gear portion 2401 and a fourth gear portion 2402 with a tooth diameter ratio greater than 1.5, further realizing the deceleration and torque increase of the power; finally, the fourth gear portion 2402 meshes with the transmission rack device 14 to drive the sector rack to rotate. The entire transmission chain increases the output torque through two decelerations and torque increases, while the special shape of the sector rack is used to achieve the conversion from rotary motion to specific trajectory motion, which can adapt to more complex mechanical action requirements and improve the functionality and adaptability of the equipment. This design provides more stable, efficient and flexible power support for the equipment by optimizing the transmission path and enhancing the transmission efficiency, significantly improving the overall performance and reliability of the equipment and extending the service life of the equipment.

[0063] As a preferred example of the present application, a first flange 201 is provided on the handle connecting rod 2, and the first flange 201 is used for the cooperation and pushing of the pushing end of the second driving rod 16. A second flange 10 is provided on the second connecting rod 8, and the second flange 10 is used for the cooperation and pushing of the pushing end of the first driving rod 15. By providing a flange on the connecting rod to cooperate with the pushing end of the driving rod, the intermediate transmission links are reduced, the energy loss is reduced, the efficiency of force transmission is improved, and the response of the entire mechanical system is faster and more accurate. In addition, the design of the flange enhances the connection strength between the connecting rod and the driving rod, avoids mechanical failures caused by loose connection or falling off, and improves the stability and reliability of the system.

[0064] This setting simplifies the mechanical structure through the cooperation between the flange and the push end of the drive rod, making the entire system more compact and lightweight, improving the performance of the mechanical system, and reducing manufacturing costs and maintenance difficulties. The position and shape of the flange can also be adjusted according to different mechanical needs to adapt to different motion trajectories and force transmission requirements, thereby improving the versatility and flexibility of the device.

As a preferred example of the present application, the second transmission device 18 includes a third transmission gear 19 and a third connecting rod 20, and the third transmission gear 19 can be driven to rotate by the second drive motor 17, one end of the third connecting rod 20 is connected to the third transmission gear 19, and the other end is connected to the sliding limiter 21, and a third slide groove 2101 is provided on the sliding limiter 21, and the third slide groove 2101 is sleeved on the first limiter column 22 on the operation box 1 and can slide relatively along it.

[0066] This setting further optimizes the structure of the switching device 400. The switching device introduces a second transmission device, specifically a crank-connecting rod structure formed by a third transmission gear 19 and a third connecting rod 20, to achieve precise control of the sliding limiter, avoiding deviation and jitter that may be caused by direct drive, thereby improving the stability and operating accuracy of the entire system, with a compact structure and reliable drive.

[0067] In the example of the present application, a high-performance PCB board is fixedly installed inside the operation box 1, and a control chip is integrated on the PCB board. The control chip realizes direct electrical connection with the first drive motor 11 and the second drive motor 17, ensuring that the drive motor can accurately respond to the instructions of the control chip and realize fast and accurate action. In order to further improve the convenience of user operation, automatic and manual adjustment buttons are carefully set on the top of the operation box, and these buttons are connected to the control chip on the PCB board through precise circuits. The user can easily switch the automatic reclosing and manual operation modes of the meter by simply pressing a button, which greatly improves the flexibility and convenience of use. In the example of the present application, the movement positions of the first drive rod 15, the second drive rod 16, and the sliding limiter 21 can be detected by sensors. For example, the rotation angles of the first worm 12 on the first drive motor 11 and the second worm on the second drive motor 17 are detected by relatively independent Hall sensors, and the movement strokes of the first drive rod 15, the second drive rod 16, and the sliding limiter 21 are calculated in combination with the gear transmission ratio, thereby satisfying the switching of the circuit breaker handle of the electric meter between the closing and opening positions and the switching of the start-up state and the failure state of the tripping protection device 200.

[0068] The electric meter with automatic closing and circuit-breaking device described in the present application not only simplifies the system structure and improves space utilization, making the entire system more compact and beautiful by optimizing the design of the external closing and circuit-breaking device of the electric meter, but also significantly reduces the power outage time and manual intervention costs caused by circuit failures through automatic detection and power supply restoration functions. At the same time, combined with remote monitoring and control technology, it further improves the safety, reliability and management efficiency of the power system, bringing great convenience and value to users and management departments.

[0069] Example 2

[0070] like Figures 1 to 7 As shown, the present application also discloses a method for controlling an electric meter with an automatic reclosing circuit breaker, comprising the following steps:

[0071] S1: The barcode and MAC address of the electric meter are obtained from the database of the power company using the smart terminal, but are not stored in the smart terminal;

[0072] S2: Pair and connect the electric meter with the smart terminal to perform initial configuration;

[0073] S3: The smart terminal monitors the status of the electric meter in real time and sends an early warning notification to the smart terminal when the status of the electric meter is abnormal;

[0074] S4: The intelligent terminal sends a signal to the control chip in the operation box. After analysis, the control chip in the operation box drives the first drive motor 11 or the first drive motor 11 and the second drive motor 17 to perform closing and opening operations.

[0075] The electric meter control method with automatic reclosing circuit breaker disclosed in the present application is an intelligent control method for opening and closing control in combination with an intelligent terminal on the basis of the electric meter with automatic closing circuit breaker as described in Example 1. First, the bar code and MAC address of the electric meter are obtained from the database of the power company through the intelligent terminal, and the information is saved in the intelligent terminal to complete the pairing connection and initialization configuration of the electric meter and the intelligent terminal. Subsequently, the intelligent terminal will monitor the working status of the electric meter in real time. Once the electric meter status is abnormal, such as overload, undervoltage or fault, the intelligent terminal will immediately send an early warning notification to the user for timely processing; when it is necessary to perform closing or opening operation, the intelligent terminal will send a signal to the control chip in the operation box. After receiving the signal, the control chip will analyze and process it, and drive the first drive motor or the first drive motor and the second drive motor at the same time according to the operation requirements, so as to complete the automatic reclosing or opening operation of the electric meter and ensure the safe and stable operation of the power system.

[0076] The electric meter control method with automatic reclosing circuit breaker device disclosed in the present application can timely detect abnormal status of the electric meter and send an early warning through the real-time monitoring function of the intelligent terminal, which helps users to timely discover and deal with power problems and avoid potential safety hazards; at the same time, the driving motor in the operation box is controlled by the intelligent terminal to perform closing and opening operations, thereby realizing the automatic reclosing function of the electric meter, which not only improves the automation level of the power system, but also can quickly restore power supply after a power failure, reduce power outage time and impact on users, and improve the reliability of the power system and user experience; moreover, the entire control process relies on the coordinated work of the intelligent terminal and the operation box, which reduces manual intervention, reduces operating costs, and also improves the operation and maintenance efficiency and management level of the power system, providing strong support for the intelligent and automated development of the power system.

[0077] As a preferred example of the present application, in step S1, before requesting to obtain the meter barcode and MAC address, the smart terminal uses username and password verification, digital certificate verification or biometric identification to authenticate the identity. After the verification is passed, only the meter barcode and MAC address corresponding to its identity can be obtained and saved to the smart terminal. This design ensures that the access rights to data are strictly controlled, greatly improves the security of data access, effectively prevents unauthorized access and data leakage risks, protects user privacy and the security of power company data, and at the same time, the smart terminal can quickly and accurately obtain the required data without screening in a large amount of data, thereby improving the efficiency of data processing, ensuring the real-time and accuracy of the data, and improving the efficiency and accuracy of the overall system.

[0078] As a preferred example of the present application, in step S2, the following steps are included:

[0079] S21: The smart terminal sends a pairing request to the electric meter through a Bluetooth pairing function or a secret key pairing function according to the obtained barcode and MAC address information;

[0080] S22: After the pairing is successful, the smart terminal sends an initialization instruction to the electric meter, including setting the basic parameters, communication protocol, and data format of the electric meter. After receiving the above initialization instruction, the electric meter performs configuration according to the instruction and feeds back the configuration result to the smart terminal;

[0081] S23: After confirming that the meter configuration is correct, the smart terminal saves the configuration information and ends the initialization process.

[0082] In this application, in Bluetooth pairing mode, the smart terminal will search for nearby Bluetooth devices, find the meter that matches the input barcode and MAC address, and initiate a pairing request; after receiving the request, the meter will verify it, and after confirming that it is correct, it will agree to pair and establish a Bluetooth connection with the smart terminal. In secret key pairing mode, the smart terminal and the meter will pre-set a pairing key. The user needs to enter this key on the smart terminal. The smart terminal then sends a pairing request containing the key to the meter. After receiving the request, the meter will check whether the key is correct. If the key matches, it will agree to pair and establish a secure connection with the smart terminal.

[0083] Through the above settings, the connection security and configuration efficiency between the electric meter and the smart terminal are significantly improved. Through the two modes of Bluetooth pairing and secret key pairing, flexible pairing methods are provided for different scenarios and needs, enhancing the reliability and security of the connection; at the same time, the sending of initialization instructions and the feedback mechanism of configuration results ensure the accuracy and consistency of the electric meter configuration, avoiding subsequent problems caused by configuration errors. The smart terminal saves the configuration information to facilitate subsequent quick connection and data analysis, thereby improving the overall system operation efficiency and user experience, and improving the intelligence level of electric meter management.

[0084] As a preferred example of the present application, in step S3, the following steps are included:

[0085] S31: The intelligent terminal is connected to the electric meter through communication, and can obtain the current, voltage, power and cost information of the electric meter in real time;

[0086] S32: The smart terminal has a built-in data processing module, which performs real-time analysis on the collected meter data to determine whether the meter is in a normal working state. If so, the process returns to S31; if not, the process proceeds to S33;

[0087] S33: The smart terminal sends a warning notification to the user through any one of text messages, APP push, voice messages, and phone calls.

[0088] This application improves the monitoring dimension by detecting the basic electrical parameters of the electric meter including current and voltage, and also incorporates power and cost information parameters, so that users can have a more comprehensive understanding of the real-time status of the electric meter, and also provide a richer data basis for subsequent data analysis. The built-in data processing module of the smart terminal can conduct a comprehensive analysis of these multi-dimensional data in real time, so as to more accurately determine whether the electric meter is in normal working condition. In addition, this application also provides a variety of early warning notification methods, including SMS, APP push, voice messages, and phone calls, etc., to ensure that users can receive early warning information in a timely manner under any circumstances, which not only improves the immediacy of the early warning, but also enhances the coverage and effectiveness of the early warning. Users can choose the most appropriate early warning method according to their preferences and actual conditions, so as to take countermeasures at the first time, effectively avoiding safety hazards or economic losses that may be caused by abnormal electric meters.

[0089] As a preferred example of the present application, in step S31, the smart terminal and the electric meter communicate to establish a communication connection through a communication protocol or a communication interface, and the electric meter sends the electric meter's current, voltage, power and cost information to the smart terminal every 1 second or every preset time. In the example of the present application, the preset interval time for the electric meter to send the electric meter status information to the smart terminal is a preset empirical value, which is greater than 1s, preferably 3s to 20s.

[0090] This application ensures the accuracy and continuity of data transmission between the electric meter and the smart terminal through the use of communication protocols or interfaces, providing a solid foundation for subsequent real-time data analysis and anomaly detection. In addition, by optimizing and setting a reasonable interval for the electric meter to send status information to the smart terminal, this application ensures the real-time nature of the data while avoiding the communication burden and energy consumption problems that may be caused by too frequent data transmission.

[0091] As a preferred example of the present application, in step S32, by presetting the normal working range threshold of current, voltage, power and cost information in the data processing module of the smart terminal, when the collected values ​​of current, voltage, power and cost information obtained by the smart terminal are outside the normal working range threshold, it is judged that the meter state is abnormal. The present application uses a threshold-based judgment method, and the smart terminal can automatically analyze the collected data in real time according to the preset threshold. Once the data is found to be beyond the normal range, the early warning mechanism can be triggered immediately without manual intervention. It can more effectively screen out abnormal data, reduce false alarms and missed alarms, improve the accuracy and reliability of monitoring, greatly improve monitoring efficiency, and reduce labor costs, making the monitoring of the meter state more efficient and convenient. At the same time, since the threshold can be adjusted and optimized according to the actual situation, the present application also has good adaptability and flexibility, and can meet the monitoring needs in different scenarios.

[0092] As a preferred example of the present application, in step S4, if the smart terminal sends an alarm notification of abnormal meter status within the preset time T 1 After that, the smart terminal sends a trip signal to the control chip without any authorized operation. If the smart terminal sends an abnormal warning notification of the meter status within the preset time T 1 Within the preset time T, the smart terminal obtains the authorization operation to keep the switch in the closed state. 2 No warning notification will be sent within this time. This setting explicitly sets the processing time window for abnormal meter status, that is, the preset time T 1 , the preset time T 1 is an empirical preset value. During this period of time, if the smart terminal does not receive any authorized operation, the control chip will automatically send a trip signal to ensure circuit safety and prevent potential dangers caused by meter abnormalities. The above settings help to achieve rapid response and automatic processing of meter status without manual intervention, greatly improving the efficiency and reliability of safety management. At the same time, this automated processing method also reduces safety hazards caused by human operational errors or delays, providing a strong guarantee for the safe operation of the power system. By setting the preset time T 1 If the authorization operation of keeping the switch closed is obtained within the preset time T 2 The mechanism of not sending warning notifications within the meter not only avoids the user trouble caused by repeated warnings, but also reflects the flexible response of smart meters to user needs. Users can temporarily turn off the warning through authorized operations after confirming that the meter is in good condition according to the actual situation, thereby enjoying a more personalized service experience.

[0093] In the example of this application, the preset time T 1 The value range is 0.5min~10min. Different preset time T is set for different abnormal parameters of the meter. 1 ; Preset time T 2 The value range is 12h~24h. The 24-hour time length can usually cover most exception handling situations, ensuring that users can have a period of quiet time after handling the exception, and at the same time will not ignore possible new exceptions due to too long time. The time limit set above can also be adjusted and optimized according to the actual application scenario and user needs. But in general, such a time setting can maximize the user experience and satisfaction while ensuring the safety of the circuit.

[0094] In the example of this application, if the smart terminal is within the preset time T 3 If the meter sends an opening signal and a closing signal for the same abnormal state, and the opening signal is greater than the closing signal, then the smart terminal will issue an abnormal warning within the preset time T2 No more warning notifications will be sent within this period. This setting is introduced by introducing a preset time T 3 The logic judgment of the opening and closing signals in the system provides a more refined control mechanism for the processing of abnormal meter status, which not only avoids the user trouble caused by repeated warnings, but also improves the operating efficiency of the smart meter system, ensuring that users will only receive warning notifications when new abnormalities that really require user attention and processing occur, reducing the sending of invalid warnings, reducing the communication burden of the system, and is conducive to improving the overall performance and stability of the system, thereby improving the user experience. As a specific example of this application, the preset time T 3 The value range is 30min~180min.

[0095] As a preferred example of the present application, the intelligent terminal sends a trip signal to the control chip in the operating box, and the second drive motor 17 of the switching device 400 is started, pushing the sliding limiter 21 to move to the lower position, so that the second drive rod 16 rotates in the direction away from the first rotating shaft 3 where the handle connecting rod 2 rotates. At the same time, the first drive rod 15 rotates under the action of the torsion spring at its own rotating shaft and rotates to a position close to the pushing portion on the second connecting rod 8. The first drive motor 11 is started, and the transmission rack device 14 rotates. At this time, the first drive rod 15 pushes the second connecting rod 8, and cooperates with the circuit breaker linkage structure through the external lever 6, so that the circuit breaker handle is disengaged from the closing safety lock in the closing position; The intelligent terminal sends a closing signal to the control chip in the operation box, the first drive rod 15 rotates in the opposite direction, the second connecting rod 8 is reset under the action of the self-resetting torsion spring and drives the external lever 6 to disengage from the circuit breaker linkage structure, the tripping protection state of the meter fails, the handle connecting rod 2 is reset under the action of the self-resetting torsion spring and drives the operating rod 4 and the circuit breaker handle inside the meter to switch from the open position to the closed position, the second drive motor 17 of the switching device 400 drives the sliding limiter 21 to move to the upper position, the second drive rod 16 is reset and drives the first drive rod 15 to rotate to a position away from the push part on the second connecting rod 8, and the meter returns to the initial state. In the example of the present application, the rotation angles of the first drive motor 11 and the second drive motor 17 are controlled by the Hall switch.

[0096] This setting, combined with the optimized structure of the electric meter with automatic closing and circuit-breaking device, realizes the remote and precise control of the electric meter circuit breaker by the smart terminal. By sending signals through the smart terminal, the electric meter status can be quickly switched without human intervention, reducing the difficulty and risk of operation. At the same time, the mechanism adopts a combination of mechanical transmission and electronic control, which not only ensures the reliability of operation but also improves the response speed.

[0097] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
