[0002] With technological advancements, the development of a "digital Internet of Things" (IoT) for online status monitoring of power equipment has become an inevitable trend. Grid operations are evolving towards intelligent, flat, and open systems, requiring in-service power equipment to possess autonomous thinking based on intelligent perception, status analysis, and health management. To build the foundation for a smart grid, many stakeholders have conducted in-depth research on the next generation of electricity meters and have developed technical solutions for smart IoT-connected meters.

[0003] With the rapid development of smart grids, the use of smart IoT energy meters has increased dramatically. However, existing homologous systems have limitations in their positioning capabilities. They can only locate the meter box, not the end-user energy meter. Data collection in homologous systems is not automated and updates are not timely. Manually entered energy meter box location information often contains large errors, resulting in "blind operation" of power equipment, especially distribution network equipment. Currently, we still rely on regular inspections by inspection personnel to detect problems. This traditional operation and maintenance model cannot promptly detect potential equipment problems. Once an energy meter fails, it can eventually develop into a serious failure.

DETAILED DESCRIPTION

[0038] The present invention will be described in more detail below with reference to the embodiments.

[0039] Example 1

[0040] See also Figures 1 to 5The IoT electric energy meter positioning module device of this embodiment includes a positioning device 100 electrically connected to the electric energy meter 200 in the electric energy meter box 300. The positioning device 100 includes a protective shell 6, and also includes an MCU processor 1, a positioning module 2, a storage module 3 and a power module 4 arranged in the protective shell 6. In addition, an expansion port 5 is also provided on the side of the protective shell 6. The expansion port 5 is electrically connected to the power module 4 and the MCU processor 1 respectively. The expansion port 5 can provide an electrical interface and can also perform hot plugging and data exchange with the electric energy meter 200.

[0041] Specifically, the MCU processor 1 is used to provide time information and can automatically reset in an abnormal state.

[0042] In this embodiment, the MCU processor 1 uses the TC8101 chip, which integrates 256KB EFLASH and 32KB SRAM, clock resources, and an external 32.768KHz crystal to realize a high-precision real-time clock (RTC), providing time information such as seconds, minutes, hours, days, weeks, months, and years, and automatically adjusting for leap years. In addition, the MCU processor 1 can also be reset when the device is abnormal.

[0043] The positioning module 2 is electrically connected to the MCU processor 1. The positioning module 2 is used to obtain positioning information and transmit the positioning information to an external memory. In this embodiment, the positioning module 2 can obtain positioning information within 60 seconds of the device being powered on, organize the data according to the device's geographic location, extract valid location information, and then store the valid location information in an external memory.

[0044] The storage module 3 is also electrically connected to the MCU processor 1 , and is used to record successful positioning events of the positioning module 2 and position movement events of the positioning module 2 .

[0045] Specifically, the positioning success event refers to the positioning time, location information and number of satellites used by the positioning module 2; the position movement event refers to the position movement time, location information before movement and location information after movement of the positioning module 2.

[0046] The power module 4 is used to provide power to the MCU processor 1 , the positioning module 2 and the storage module 3 .

[0047] In this embodiment, the power module 4 is designed to protect against abnormal conditions such as lightning surge, overvoltage, short circuit, etc., thereby ensuring the reliability of the device.

[0048] At the same time, the power module 4 inputs +5V DC from the expansion port 5 and then outputs +3.3V DC.

[0049] Furthermore, the protective shell 6 includes a vertical shell 602 and an extension shell 601, the expansion port 5 is installed at the top of one side of the vertical shell 602, the extension shell 601 is integrally connected to the top of the other side of the vertical shell 602, and a sliding shell 7 is provided at the bottom of the extension shell 601, and the positioning module 2 is provided inside the sliding shell 7.

[0050] As can be seen from the above description, the beneficial effect of the present invention is that, by setting the positioning device 100, it is possible to directly interact with the electric energy meter 200 in the electric energy meter box 300 through the expansion port 5, thereby improving the convenience of data flow; the setting of the positioning module 2 can confirm the location information of the corresponding electric energy meter, and the positioning module 2 can also transmit the location information to the external memory in real time, thereby being able to monitor the position change of the electric energy meter in real time, so that maintenance personnel can find the electric energy meter with a changed position in time. At the same time, when the electric energy meter is damaged and needs repair, it is convenient for maintenance personnel to promptly confirm the location information of the corresponding faulty electric energy meter, which greatly facilitates on-site operation and maintenance work, especially when the electric energy meter fails, power outages, etc. occur, it can ensure that the operation and maintenance personnel arrive at the scene quickly and accurately. The location information collected by the positioning module 2 can also be used to analyze the usage pattern and demand of the power grid, and assist the power supply company in optimizing the operation and maintenance plan of the power grid; the setting of the MCU processor 1 and the storage module 3 provides the possibility for customized function development and remote upgrade, so that the positioning device 100 can be personalized according to the needs of different customers.

[0051] Example 2

[0052] The IoT electric energy meter positioning module device of this embodiment is based on the above-mentioned embodiment 1, and the overall mechanical connection relationship of the protective shell 6 is further defined as follows:

[0053] See also Figures 3 to 8 The top of the sliding shell 7 is bonded to the bottom of the extension shell 601 by a thermal tape, and the side of the sliding shell 7 is slidingly connected to the vertical shell 602. The bottom of the sliding shell 7 is provided with a triggering device 500 for triggering the adjusting device 400 provided inside the meter box 300.

[0054] From the above description, it can be seen that when the temperature inside the meter box 300 rises abnormally, the thermal tape will lose its viscosity, and the sliding shell 7 and the extension shell 601 will be separated, and the sliding shell 7 will fall downward. In the process of the sliding shell 7 falling downward, the trigger device 500 will trigger the adjustment device 400 to cool the inside of the meter box 300, effectively reducing the safety risk of accidents. When the sliding shell 7 falls, the position of the positioning module 2 also changes, which can assist maintenance personnel to locate and find the position of the problematic electricity meter in time, which is not only conducive to reducing the safety risk of accidents, but also can improve maintenance efficiency.

[0055] Specifically, a card slot is provided on the side of the vertical housing 602, and a card rod is provided on the side of the sliding housing 7 to be slidably engaged in the card slot.

[0056] Furthermore, the trigger device 500 includes a mounting shell 11, a falling block 20, a clamping mechanism, a boom 8 and a trigger button 10. The mounting shell 11 is a circular cylindrical structure. The falling block 20 and the clamping mechanism are both arranged inside the mounting shell 11, and the clamping mechanism is arranged at the top of the falling block 20 and the clamping mechanism is clamped and connected to the falling block 20. The clamping mechanism releases the falling block 20 when the mounting shell 11 falls, and the boom 8 is rotatably arranged at the top of the clamping mechanism. The top of the boom 8 moves through the mounting shell 11 and then moves upward through the sliding shell 7, and the top of the boom 8 is detachably hooked on the top of the extension shell 601. The trigger button 10 is arranged directly below the falling block 20. In particular, when the falling block 20 falls to the top of the trigger button 10, the top of the falling block 20 is still wrapped inside the mounting shell 11.

[0057] From the above description, it can be seen that the clamping mechanism releases the falling block 20 when the mounting shell 11 falls, that is, when the temperature inside the meter box 300 rises abnormally, the falling block 20 is released, and the falling block 20 falls onto the trigger button 10, and then the trigger adjustment device 400 is controlled by the trigger button 10 to start cooling the inside of the meter box 300. The setting of the hanger 8 can rotate the hanger 8 to release the hanger 8 and the extension shell 601, and then push the hanger 8 downward so that the clamping mechanism re-clamps the falling block 20, and then the trigger button 10 can be released to achieve the reset of the trigger button 10.

[0058] Furthermore, the clamping mechanism includes a movable block 12, a return spring 24 and two symmetrically arranged arc-shaped hinged rods that are both hinged to the movable block 12. The arc-shaped hinged rod includes an integrally arranged bending rod 13 and a hook 17. The hook 17 is arranged at the bottom end of the bending rod 13, and the connection between the hook 17 and the bending rod 13 is hinged to the movable block 12 through a hinge pin. The bending part of the bending rod 13 is slidably clamped in the slide groove 16 provided on the inner wall of the mounting shell 11; the reset rod 22 is fixedly connected to the opposite side of the two bending rods 13 and near the hinge point. A fixed plate 23 is fixedly sleeved on the reset rod 22, and the return spring 24 is fixedly arranged between the two fixed plates 23. The top of the mounting shell 11 is provided with an extrusion port 14 for squeezing the two bending rods 13 and releasing the two hooks 17; the side where the two hooks 17 are close to each other is an arc-shaped structure.

[0059] Furthermore, a connecting rod 18 is fixedly connected to the top of the falling block 20, and a clamping plate 19 is fixed to the top of the connecting rod 18, and the top edge of the clamping plate 19 is arranged in an arc shape; the distance between the two hooks 17 is greater than the diameter of the connecting rod 18, and the distance between the two hooks 17 is smaller than the diameter of the clamping plate 19.

[0060] From the above description, it can be seen that the function of the clamping mechanism is to clamp the connecting rod 18 at the top of the falling block 20. When the mounting shell 11 descends along with the sliding shell 7, the clamping mechanism can release the connecting rod 18 so that the falling block 20 falls and squeezes the trigger button 10.

[0061] Specifically, when the clamping mechanism clamps the connecting rod 18, the two hooks 17 clamp the clamping plate 19, thereby preventing the falling block 20 from falling;

[0062] When the clamping mechanism releases the connecting rod 18, since the mounting shell 11 is falling and the suspension rod 8 is stationary, the extrusion port 14 squeezes the top ends of the two bending rods 13, and the top ends of the two bending rods 13 move closer to each other under the action of the hinge point, while the bottom ends of the two bending rods 13 move away from each other, thereby driving the two hooks 17 away from the release clamping plate 19, thereby releasing the falling block 20;

[0063] When it is necessary to re-clamp the connecting rod 18, the hanger 8 is loosened so that the hanger 8 drives the movable block 12 to descend. When the movable block 12 descends, the extrusion port 14 gradually loosens the two bending rods 13, and the two bending rods 13 return to their original positions under the action of the reset spring 24 and return to the clamping state; the hanger 8 continues to move downward, and the hook 17 fits the card plate 19. The arc at the top of the card plate 19 will be in contact with the arc structure on the side of the hook 17. Finally, the card plate 19 squeezes the two hooks 17 apart, and then the card plate 19 can be re-clamped between the two hooks 17, so that the clamping mechanism re-clamps the connecting rod 18, and then the hanger 8 is pulled upward to re-install the hanger 8 and the extension shell 601.

[0064] In this embodiment, a limit block 21 is set between the two hooks 17, and the limit block 21 is fixed on the movable block 12. The setting of the limit block 21 can limit the rising position of the card plate 19, preventing the card plate 19 from being lifted too high and causing the reset spring 24 to be separated from the installation position.

[0065] Furthermore, an extension block 9 is extended and fixed to the side of the vertical shell 602 , and a trigger button 10 is arranged on the top of the extension block 9 .

[0066] Example 3

[0067] The IoT electric energy meter positioning module device of this embodiment, based on the above-mentioned second embodiment, further defines the overall mechanical connection relationship of the adjustment device 400 as follows:

[0068] See also Figure 9 、 Figure 10 and Figure 11 The regulating device 400 includes a mounting plate 26 mounted in the meter box 300, and also includes a driving component and a reciprocating motion component.

[0069] Specifically, the driving assembly includes a rotating disk 30 and a driving mechanism for adjusting the upper and lower positions of the rotating disk 30 and capable of driving the rotating disk 30 to rotate. The driving mechanism is fixedly mounted on the top of the mounting plate 26 and electrically connected to the power module 4. The rotating disk 30 is mounted at the front end of the driving mechanism, and a circular card slot 31 is provided at the front end of the rotating disk 30, wherein the driving mechanism is started by the trigger button 10.

[0070] Among them, the reciprocating motion component includes a socket plate 33 fixed to the front end of the mounting plate 26 and a sliding plate 28 slidably socketed on the front end of the socket plate 33. A number of nozzles 29 are installed in sequence from top to bottom at the front end of the sliding plate 28. Each nozzle 29 is connected to a storage tank set in the meter box 300 through a hose. The storage tank is filled with fire extinguishing agent. In particular, the nozzle 29 is also activated by the trigger button 10. The top of the sliding plate 28 is rotatably connected to a movable pin 32, and the free end of the movable pin 32 is slidably set in a circular slot 31.

[0071] Furthermore, the driving mechanism includes a driving motor 34 , a mounting block 27 , a rotating block 35 , an adjusting screw 36 and an adjusting slider, wherein the driving motor 34 is electrically connected to the trigger button 10 .

[0072] The mounting block 27 is fixed to the top of the mounting plate 26, the drive motor 34 is installed at the rear end of the mounting block 27, and the rotating block 35 is rotatably installed at the front end of the mounting block 27. The output shaft of the drive motor 34 rotates through the mounting block 27 and is fixedly connected to the rotating block 35. A vertical guide groove is provided at the front end of the rotating block 35, and an adjusting screw rod 36 is arranged in the guide groove and both ends of the adjusting screw rod 36 rotate and pass through the rotating block 35. The adjusting slider is arranged in the guide groove and is threadedly sleeved with the adjusting screw rod 36. The front end of the adjusting slider extends out of the guide groove and is fixedly connected to the rotating disk 30.

[0073] As can be seen from the above description, after the trigger button 10 is triggered, the drive motor 34 is started, and the drive motor 34 can drive the rotating block 35 to rotate. Since the rotating block 35 is installed and connected to the rotating disk 30, the rotating disk 30 rotates synchronously. During the rotation of the rotating disk 30, under the action of the circular slot 31, the movable pin 32 is driven to move in the circular slot 31, and then the sliding plate 28 can be driven up and down by the movable pin 32, so that the nozzle 29 on the sliding plate 28 can take care of the electricity meters in different positions, so that the inside of the meter box 300 can be better cooled.

[0074] At the same time, by adjusting and rotating the adjusting screw 36, the adjusting screw 36 will drive the adjusting slider to move in the guide groove, and then the rotating disk 30 can be driven to adjust its position by adjusting the slider. By adjusting the position of the rotating disk 30, the rotating block 35 will rotate during the rotation process, and the rotation center of the rotating disk 30 will change, and then the up and down sliding distance of the sliding plate 28 can be adjusted, and then it can adapt to electric energy meters with different installation distances and electric meter boxes 300 of different sizes without redesigning the length of the sliding plate 28.

[0075] Furthermore, a through slot is formed at the front end of the sleeve plate 33 to allow the nozzle 29 to pass through.

[0076] The working principle of the present invention is as follows: by setting up a positioning device 100, it is possible to directly interact with the electric energy meter 200 in the electric energy meter box 300 through the expansion port 5, thereby improving the convenience of data flow; the setting of the positioning module 2 can confirm the location information of the corresponding electric energy meter, and the positioning module 2 can also transmit the location information to the external memory in real time, thereby being able to monitor the position changes of the electric energy meter in real time, so that maintenance personnel can find the electric energy meter with a changed position in time. At the same time, when the electric energy meter is damaged and needs repair, it is convenient for maintenance personnel to confirm the location information of the corresponding faulty electric energy meter in time, which greatly facilitates on-site operation and maintenance work, especially when the electric energy meter fails, power outages, etc. occur, it can ensure that the operation and maintenance personnel arrive at the scene quickly and accurately. The location information collected by the positioning module 2 can also be used to analyze the usage pattern and demand of the power grid, and assist the power supply company in optimizing the operation and maintenance plan of the power grid; the setting of the MCU processor 1 and the storage module 3 provides the possibility for customized function development and remote upgrade, so that the positioning device 100 can be personalized according to the needs of different customers.

[0077] When the temperature inside the meter box 300 is too high, the thermal tape will lose its stickiness, and the sliding shell 7 will slide down and fall. When the sliding shell 7 moves, it will drive the positioning module 2 to move. The positioning module 2 can transmit the changed positioning information to the outside in a timely manner, thereby assisting maintenance personnel to quickly check the high-temperature meter box 300, which can effectively help maintenance personnel quickly locate and eliminate safety hazards. At the same time, in the process of the sliding shell 7 falling downward, the clamping mechanism will release the falling block 20, and the falling block 20 will squeeze the trigger button 10, thereby starting the adjustment device 400, and the driving motor 34 and the nozzle 29 of the adjustment device 400 are started.
