Description

Technical Field

[0001] This utility model relates to the field of gas meter technology, specifically to NFC smart meter seals. Background Technology

[0002] A gas meter seal is a special anti-tampering sealing device applied by a gas company or authorized agency to key parts of a gas metering device (such as the casing, valves, regulator interfaces, etc.). It typically uses disposable, easily damaged materials (such as lead seals, plastic seals, anti-counterfeiting labels, etc.) and is assigned a unique code. Its core function is to ensure the integrity and unauthorized opening of the gas meter during its installation, use, and calibration cycle by combining physical obstruction with information traceability, thereby effectively preventing unauthorized disassembly, parameter modification, or malicious gas theft.

[0003] However, the existing gas meter seals have the following problems: the existing physical meter seals cannot record the specific time and operator of the removal; manual inspections may miss some items and cannot verify the authenticity of the personnel on duty in real time; users cannot easily obtain their own gas facility safety inspection reports; and the single physical protection is easily cracked and restored by professional tools. In view of this, this technical solution designs an NFC smart watch cover. Utility Model Content

[0004] The purpose of this invention is to provide an NFC smart watch cover to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The NFC smart meter seal is installed on the gas pipe of the gas meter. It includes a meter seal base ring and a meter seal retaining ring. The meter seal base ring and the meter seal retaining ring are connected by a snap-fit, forming a circular channel that is snapped onto the gas pipe for positioning. At the same time, an NFC chip compartment is opened inside the end of the meter seal base ring away from the meter seal retaining ring. An NFC chip slot is provided in the center of the NFC chip compartment, and an NFC chip is installed in the NFC chip slot. A compartment cover is snap-fitted onto one side of the NFC chip compartment, and the opening and closing of the NFC chip compartment is controlled by the compartment cover. The NFC chip is pre-written with a unique identification code (UID code). The NFC chip itself does not require power; it obtains energy through the phone's NFC antenna for communication.

[0006] Compared with the existing technology, the beneficial effects of this utility model are: to realize dual anti-counterfeiting verification of the location and time of security personnel, completely eliminate missed inspections and false reports, and at the same time, the physical structure and electronic authentication provide dual protection, leaving irreversible evidence of damage for any disassembly; users can obtain security inspection reports with geographic tags in real time, improving service transparency; the passive NFC chip eliminates the cost of power supply and maintenance, and can be read by mobile phones immediately. The anti-hacking level is improved by using an inverted double locking structure (base ring-locking ring, compartment cover-chip compartment). Attached Figure Description

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Please see Figures 1-4 An NFC smart meter seal is installed on the gas pipe 19 of the gas meter 20. It includes a meter seal base ring 10 and a meter seal retaining ring 11. The meter seal base ring 10 and the meter seal retaining ring 11 are connected by a snap-fit ​​mechanism, forming a circular channel that is positioned on the gas pipe 19. Specifically, the meter seal base ring 10 and the meter seal retaining ring 11 form an annular channel surrounding the gas pipe 19 through the snap-fit ​​structure. Simultaneously, an NFC chip compartment 14 is located inside the meter seal base ring 10 at the end furthest from the meter seal retaining ring 11. The end of the sealing ring 11 is provided with an NFC chip compartment 14, and the center of the NFC chip compartment 14 is provided with an NFC chip slot 16. That is, the NFC chip slot 16 is located in the center plane of the inner wall of the NFC chip compartment 14, and its size matches that of a standard NFC chip. An NFC chip is installed in the NFC chip slot 16. At the same time, a compartment cover 15 is snap-fitted onto one side of the NFC chip compartment 14. That is, the opening end of the NFC chip compartment 14 is connected to the compartment cover 15 through a snap-fit ​​structure, and the opening and closing of the NFC chip compartment 14 is controlled by the compartment cover 15. The NFC chip is pre-written with a unique identification code (UID). The NFC chip itself does not require a power supply; it obtains power through the phone's NFC antenna for communication. The specific operation process is as follows: The gas company has equipped its safety inspectors with NFC-enabled smartphones that have a built-in dedicated app.

[0017] After arriving at the user's home and completing a physical inspection of gas meter 20, the safety inspector opened the safety inspection APP on their mobile phone.

[0018] Bring the back of your phone close to area 14 of the NFC chip compartment on the watch cover. The app will automatically wake up and read the unique UID code from the chip.

[0019] While reading the UID, the app automatically calls the phone's GPS and network positioning functions to obtain accurate latitude and longitude coordinates, and obtains an unalterable Beijing timestamp from the network.

[0020] The app packages three key data points—UID (representing which meter), location information (proving on-site presence), and time information (proving arrival time)—and uploads them in real-time to the gas company's cloud server database via mobile internet.

[0021] The server backend system can automatically generate reports by comparing the inspection dates in the scheduled task list with the actual sign-in records. The reports clearly show which forms have been inspected, which have been missed, and the walking routes of the security personnel, thereby achieving effective supervision and preventing missed inspections. Specifically, the snap-fit ​​structure of the meter seal base ring 10 and the meter seal retaining ring 11 includes an inverted snap-fit ​​pin 12 and a snap-fit ​​hole 13 disposed on the opposite side walls of the two. After the snap-fit ​​pin 12 is inserted into the snap-fit ​​hole 13, it forms an irreversible lock. That is, the snap-fit ​​pin 12 and the snap-fit ​​hole 13 are respectively disposed between the side walls of the meter seal base ring 10 and the meter seal retaining ring 11 that are in contact with each other. The snap-fit ​​pin 12 and the snap-fit ​​hole 13 adopt an inverted snap-fit ​​structure. Once the two are snapped together, they will lock and cannot be pulled out in the opposite direction. This ensures that any attempt to forcibly open the meter seal (whether it is to disassemble the meter seal to modify the gas meter / pipeline or simply to remove it) will cause the fragile snap-fit ​​pin or the edge of the snap-fit ​​hole to break. The snap-fit ​​structure between the cover 15 and the NFC chip compartment 14 includes at least two snap-fit ​​strips 17 located inside the cover 15. That is, multiple snap-fit ​​strips 17 are provided at the four corners of the inner side of the cover 15. The inner wall of the NFC chip compartment 14 corresponding to the snap-fit ​​strips 17 is provided with a card slot 18. The snap-fit ​​strips 17 and card slots 18 are snap-fitted together. The snap-fit ​​strips 17 and card slots 18 also adopt an inverted snap-fit ​​design to maintain a one-time locked connection between the cover 15 and the NFC chip compartment 14. The aforementioned inverted snap-fit ​​connection achieves anti-theft and anti-tampering functions.

[0022] In this embodiment of the invention, the unique UID of the NFC chip serves as a "digital ID card" to associate the physical seal with a virtual record in the database. After security personnel use their mobile phones to read the UID of the seal, not only is the "visit check-in" completed in the background, but the security check list for that household will also be displayed on the APP interface. Based on the on-site inspection, security personnel fill in the inspection results on the APP (such as: "valve normal", "hose needs to be replaced", "minor leak", etc.) and can take photos as evidence; When the security check report data is submitted, it will be associated with the UID and user address information that were just read (which has been bound to the backend database) and uploaded to the server together. The server-side system binds this latest security inspection report to the user's account (usually identified by the "owner's mobile phone number"); After a user downloads the relevant APP, registers and logs in using their mobile phone number, the system will automatically push all associated addresses (properties) under that mobile phone number and the corresponding gas meter safety inspection reports to the user. Users can easily view detailed safety inspection reports for all previous inspections, especially the current one, to understand the safety status of their home's gas facilities, increasing service transparency and improving user experience. This achieves the purpose of the safety inspection report viewing function.

[0023] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control. The meter seal base ring 10 and meter seal card ring 11 are wrapped around the gas pipe 19 and locked by inserting the card pin 12 into the card hole 13 to form a ring channel. The safety inspector uses an NFC mobile phone to approach the chip compartment 14 area. The APP reads the UID code and automatically associates it with the GPS location and Beijing timestamp. The UID code, location information and time information are packaged and uploaded to the cloud database in real time. The cloud compares the planned task table to generate a missed inspection report and inspection path. The APP retrieves the user safety inspection list bound to the UID. The NFC chip is pre-written with a unique UID code, which is then linked to gas user information and safety inspection schedules in the cloud database.

[0024] The inspection results are filled out on-site, photos are taken, and the report is sent to the client APP via the user's mobile phone number.

[0025] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that each part in this application is made of metal or plastic material with suitable strength in the relevant field to ensure that its structural rigidity meets the actual requirements.

[0026] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
