[0002] The gas pressure regulating box is an important part of the gas transmission and distribution system. It is widely used due to its compact structure, small footprint, investment savings, and easy installation and use. The basic configuration of the box includes inlet and outlet valves, filters, pressure regulators and corresponding measuring instruments. It can also be equipped with bellows compensators, overpressure relief valves, overpressure cut-off valves and other auxiliary safety equipment. At the same time, according to the use and user requirements, it can be assembled into a single-way, dual-way or multi-way gas pressure regulating box.

[0003] At present, gas safety inspectors need to conduct regular inspections on the gas pressure regulating box to ensure the safety of the gas pressure regulating box. However, the current inspection process is that the security inspectors inspect the equipment of the gas pressure regulating box one by one in the order of numbers and then register them. Although GPS is currently used to locate the security inspectors and determine whether the security inspectors have reached the equipment location of the gas pressure regulating box, it is impossible to determine whether the security inspectors have opened the door of the equipment of the gas pressure regulating box. Therefore, it is impossible to ensure whether the security inspectors have opened the door of the equipment of the gas pressure regulating box. Therefore, the technical solution of this application is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an RFID-based device for auxiliary inspection of a gas pressure regulating box, so as to solve the problem in the above background technology that it is impossible to ensure whether the security personnel have opened the door of the gas pressure regulating box.

[0016] The present application provides a device for auxiliary inspection of a gas pressure regulating box based on RFID, including a pressure regulating box, a box door is arranged on the pressure regulating box; an RFID chip is arranged inside the pressure regulating box; the RFID chip is used to store the identification mark of the pressure regulating box, and the RFID chip UID is recorded in the pressure regulating box file to make the RFID chip uniquely correspond to the pressure regulating box. By arranging the RFID chip in the pressure regulating box, when the pressure regulating box is in a closed state, the inside of the pressure regulating box is in a metal-sealed state. At this time, the signal of the RFID chip is mostly shielded. When the security inspector arrives at the equipment of the gas pressure regulating box and does not open the box door, the RFID card reader of the security inspector cannot read the UID of the RFID chip inside the pressure regulating box. The security inspector needs to open the box door before reading the UID of the RFID chip. After opening the box door, the security inspector then conducts security inspection on the components in the pressure regulating box. The solution of the present application can ensure that the security inspector must open the box door, and eliminate the problem that the security inspector does not open the box door after arriving at the location of the pressure regulating box and directly registers that the security inspector has been inspected.

[0022] See also Figures 1 to 4 In an embodiment of the utility model, a device based on RFID for auxiliary inspection of a gas pressure regulating box includes a pressure regulating box body 1, on which a box door 2 is arranged; an RFID chip 3 is arranged inside the pressure regulating box body 1; the RFID chip 3 is used to store an identification mark of the pressure regulating box body 1, and the RFID chip 3 UID is recorded in the pressure regulating box body 1 file to make the RFID chip 3 uniquely correspond to the pressure regulating box body 1.

[0023] In this embodiment, the RFID chip 3 is a wireless radio frequency identification technology, namely, Radio Frequency Identification (RFID), which is a kind of automatic identification technology and performs non-contact two-way data communication through wireless radio frequency.

[0024] In this embodiment, the above-mentioned pressure regulating box body 1 is usually installed outdoors, and the gas safety inspectors need to conduct regular inspections on the equipment of the gas pressure regulating box to ensure the safety of the equipment of the gas pressure regulating box. However, the current security inspection process is that the security inspectors check the equipment of the gas pressure regulating box one by one in the order of numbering and then register them. Although GPS is currently used to locate the security inspectors and it can be determined whether the security inspectors have arrived at the equipment location of the gas pressure regulating box, it is impossible to determine whether the security inspectors have opened the door 2 of the gas pressure regulating box. Therefore, the present application sets an RFID chip 3 inside the pressure regulating box body 1, and the RFID chip 3 can store a predetermined UID. In this embodiment, any identifier can be used as an identification identifier in this application, such as a combination of letters, numbers, character strings, etc., and this application does not limit it.

[0025] For example, we can directly use the built-in number of each voltage regulating box 1 as the aforementioned identification mark. After the security personnel arrives at the current voltage regulating box 1 with the RFID card reader, they open the door 2, bring the RFID card reader close to the built-in RFID chip 3, and start the inspection. When the inspection is completed, the security personnel are required to read and identify the RFID chip 3 again to confirm that the inspection is completed. The time from start to end needs to be greater than the predetermined time length, so as to monitor the security personnel inspecting the voltage regulating box 1.

[0026] In this embodiment, of course, the RFID chip 3 in this application can also be connected to the Internet of Things system to register notes each time the U ID in the RFID chip 3 is read. It should be noted that the Internet of Things system belongs to the conventional technical means in this field, and this application does not make improvements to the method of accessing the Internet of Things and the related data flow process, but only uses the existing Internet of Things technology to read and write the RFID chip 3 in this application.

[0027] In a specific embodiment, the RFID chip 3 is installed in the voltage regulating box 1 through the base 4, and the assembly formed by the base 4 and the voltage regulating box 1 is used to shield the signal of the RFID chip 3, so that the RFID chip 3 reader located outside the voltage regulating box 1 cannot read the signal of the RFID chip 3 in the voltage regulating box 1 whose door 2 is not opened.

[0028] In this embodiment, by setting a base 4 in the voltage regulating box 1, the shielding effect of the RFID chip 3 is further improved. In this way, it can be further ensured that when the voltage regulating box 1 is in a closed state, the internal RFID chip 3 cannot be read by the RFID chip 3 reader outside the box. In this way, when the security personnel arrive at the voltage regulating box 1, they can only read the identification mark in the RFID chip 3 after opening the box door 2. This method ensures that the security personnel do not go through the motions and can only open the box door 2. Of course, this application cannot guarantee that the security personnel will check the components in the voltage regulating box 1 100%, but the technical solution of this application improves the problem that the security personnel go through the motions through GPS positioning in the current security inspection process, prompting the security personnel to open the box door 2 and maintain it for a period of time before closing the box door 2. Under the current security inspection situation, the technical solution of this application can effectively solve this technical problem.

[0029] In a specific embodiment, the base 4 includes: a base 5 and a cover plate 6; a mounting groove 7 is opened on the base 5, the RFID chip 3 is installed in the mounting groove 7, the cover plate 6 is inserted into the base 5, and the cover plate 6 can slide relative to the base 5 to open or close the mounting groove 7.

[0030] In this embodiment, as a preferred implementation, the base 4 provided by the present application includes a substrate 5 and a cover plate 6, and both the cover plate 6 and the substrate 5 are made of RFID shielding materials to further improve the shielding effect of the RFID chip 3, and further ensure that when the box door 2 is not opened, the RFID chip 3 located inside the voltage regulating box 1 is not recognized by the RFID chip 3 reader outside the voltage regulating box 1. Specifically, when the box is closed, the cover plate 6 covers the opening of the installation slot 7, and the cover plate 6 completely covers the installation slot 7. At this time, the RFID chip 3 in the installation slot 7 can further improve the shielding effect of the RFID chip 3 under the combined shielding of the base 4 and the voltage regulating box 1.

[0031] During use, when the security inspector arrives at the position of the voltage regulating box 1, he opens the box door 2 and slides the cover plate 6 so that the cover plate 6 opens the installation slot 7, and the RFID chip 3 in the installation slot 7 is exposed. At this time, the security inspector uses the RFID card reader to identify the RFID chip 3. After the identification is successful, the background records the identification mark and identification time of the voltage regulating box 1 identified by the security inspector. After the security inspector completes the security inspection, he uses the RFID card reader to identify the RFID chip 3 again. After the identification is successful, the background records the identification mark and identification time of the voltage regulating box 1 identified by the security inspector for the second time, and counts the time interval between the two identifications. After the interval is greater than the predetermined time length, according to the current judgment condition, it is considered that the security inspector has completed the predetermined security inspection work. The above-mentioned predetermined time length can be 5 minutes or 10 minutes, which can be set by the user, and this application does not limit it. It can be understood that in the current security inspection process, the security inspection time length is usually filled in by the security inspector himself. By adopting the solution of this application, the security inspection time length can be determined by the time interval of identifying the RFID chip 3, making the security inspection time length more credible.

[0032] In this embodiment, the RFID shielding material includes at least one of aluminum, steel, copper, nickel, natural fiber and synthetic fiber. This application does not limit the type of the RFID shielding material. In this application, any material that can shield the RFID chip 3 is sufficient. Of course, the higher the shielding effect, the better.

[0033] In a specific embodiment, a slide groove is provided on the side of the base 5, and the cover plate 6 is inserted into the slide groove, and the cover plate 6 can slide in the slide groove. The above structure can adjust the position of the cover plate 6 by pulling the cover plate 6, which is simple to operate and convenient to use.

[0034] In a specific embodiment, the base 4 is a boss structure, and the mounting groove 7 is provided on the top surface of the boss structure. This arrangement can make the distance between the RFID chip 3 and the inner wall of the voltage regulating box 1 farther, further improving the shielding effect of the RFID chip 3.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
