Description

Technical Field

[0001] The utility model belongs to the technical field of petroleum equipment information management, and specifically relates to an assembled radio frequency electronic nameplate used for petroleum equipment management. Background Art

[0002] At present, the information management of equipment is mainly realized by UHF radio frequency tags or NFC radio frequency tags. The UHF radio frequency tags have a long recognition distance, generally up to meters, can be read and written in groups, and require a specific recognition terminal; the NFC radio frequency tags have a short recognition distance, generally need to be close to the recognition, the recognition terminal is common, and most mobile phones on the market support recognition. In the information management of equipment, UHF radio frequency tags and NFC radio frequency tags each have different advantages. Therefore, in the circulation of equipment, it is often necessary to use two tags to jointly manage the equipment. However, in the current equipment information management, most of them are realized by installing two radio frequency tags separately, that is, a device is installed with both UHF radio frequency tags and NFC radio frequency tags. This dual installation method not only increases the complexity of installation, but also affects the overall aesthetics and ease of use of the equipment.

[0003] Another example is the Chinese invention patent "A dual-frequency RFID tag for clothing management" with announcement number CN110766122A, which discloses a dual-frequency RFID tag for clothing management, including a UHF tag antenna, an HF NFC coil antenna, and a dual-frequency RFID electronic tag chip. The UHF tag antenna and the HF NFC coil antenna are both connected to the dual-frequency RFID electronic tag chip. The UHF tag antenna and the HF NFC coil antenna use a dual-frequency RFID electronic tag chip to connect and work. The dual-frequency RFID electronic tag chip has a UHF frequency band and a HF frequency band. The UHF frequency band complies with the ISO180006C protocol, and the HF frequency band complies with the ISO15693 protocol. The UHF tag antenna and the dual-frequency RFID electronic tag chip constitute the UHF tag part, and the HF NFC coil antenna and the dual-frequency RFID electronic tag chip constitute the HF tag part. This technical solution effectively solves the cost problem caused by the need to match two chips with different frequency bands in the traditional method by integrating a single dual-frequency RFID electronic tag chip. However, applying this technology to the field of information management technology for petroleum equipment faces certain limitations. Specifically, the dual-frequency chip has fixed operating frequency bands (UHF and HF) and identification distances, lacks flexibility, and is difficult to meet the identification requirements of petroleum equipment in different application scenarios, thus limiting its adaptability.

[0004] Therefore, in view of the complexity and inconvenience of dual-tag installation in equipment information management and the lack of flexibility in the use of existing dual-frequency RFID tags, an innovative solution is urgently needed. Utility Model Content

[0041] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. For the convenience of description, the description of the relative position relationship of each component is described according to the layout of the drawings in the specification, such as: the position relationship of front, back, up, down, left, right, etc. is determined according to the layout direction of the drawings in the specification.

[0042] Example 1

[0043] like Figure 1-3As shown, an assembled radio frequency electronic nameplate for petroleum equipment management includes a metal base 1 and a plastic top cover 2. The metal base 1 has label mounting grooves 3 and double-sided foam adhesive 15 on opposite sides thereof. The end of the metal base 1 has a mounting hole 8 for mounting the radio frequency electronic nameplate on the petroleum equipment.

[0044] The double-sided foam adhesive 15 is suitable for installation on uneven surfaces or slightly curved surfaces of petroleum equipment because it has a certain thickness of soft pad. When used, the double-sided foam adhesive can be used alone to fix the metal base 1 to the petroleum equipment, or fixed through the mounting hole 8, or a combination of the two installation methods. In addition, on the smooth and flat surface of some petroleum equipment, a single layer of double-sided adhesive can also be used to replace the double-sided foam adhesive 15.

[0045] The tag installation slot 3 is equipped with an NFC radio frequency tag 4 and a UHF radio frequency tag 5 for the identification terminal to read the identification information of the petroleum equipment. The NFC radio frequency tag 4 and the UHF radio frequency tag 5 both have a non-chip surface 6 and a chip surface 7 facing the identification terminal. An absorbing material layer 9 is fixed to the bottom of the tag installation slot 3, and the absorbing material layer 9 is fixedly connected to the non-chip surface 6.

[0046] According to the usage scenario, the tag installation slot 3 can be freely matched and assembled with NFC radio frequency tags 4 and / or UHF radio frequency tags 5. The NFC radio frequency tags 4 and UHF radio frequency tags 5 are used for the identification terminal to read the petroleum equipment identification information carried on the NFC radio frequency tags 4 and the UHF radio frequency tags 5 respectively. The NFC radio frequency tags 4 and the UHF radio frequency tags 5 are respectively responsible for carrying the identification information of the petroleum equipment, which is convenient for reading by different identification terminals. Specifically, the code information on the NFC radio frequency tag 4 can be read by a terminal equipped with NFC identification capability, while the code information on the UHF radio frequency tag 5 is exclusively read by a terminal with UHF identification capability.

[0047] The utility model can effectively shield electromagnetic waves and block interference signals that may be generated on the metal surface through the built-in absorbing material layer 9, thereby ensuring the stable operation of the NFC tag 4 and the UHF radio frequency tag 5 in a complex metal environment. It can not only improve the reading and writing performance of the radio frequency tag, but also enhance the reliability of data transmission, providing strong technical support for the information management of petroleum equipment.

[0048] The plastic top cover 2 is fixed on the metal base 1 and seals the label installation groove 3, and the inner surface of the plastic top cover 2 is fixedly connected to the chip surface 7, and the outer surface of the plastic top cover 2 is respectively provided with a QR code recognition area 16 and a visual information display area 17.

[0049] The QR code recognition area 16 is printed with a QR code, and the QR code carries the identification information of the petroleum equipment for reading by the identification terminal; the visual information display area 17 displays the key information of the petroleum equipment, such as: equipment name, self-numbering, company information, etc.; in addition, in some embodiments, the radio frequency electronic nameplate can be further expanded. After expansion, the visual information display area 17 is not limited by the size of the radio frequency electronic nameplate, and can display the key parameters and key detection and inspection information of the equipment, such as equipment rated power, rated transmission, rated torque, equipment rating, equipment safety status, next detection time, etc., so that equipment operators can judge the equipment detection and inspection status on site.

[0050] In order to improve the flexibility and reliability of the use of the radio frequency electronic nameplate of the utility model and enhance the efficiency and convenience of information management of petroleum equipment, the petroleum equipment identification information carried by the NFC radio frequency tag 4, the UHF radio frequency tag 5, the QR code recognition area 16 and the visual information display area 17 can be the same or different.

[0051] When in use, the operator first selects the most appropriate identification method according to the usage scenario, and uses the identification terminal to read the oil equipment identification information carried in the NFC radio frequency tag 4, the UHF radio frequency tag 5 and the two-dimensional code identification area 16 respectively, and the identification terminal is connected to the equipment information management system; then, the operator enters the identified oil equipment identification code into the equipment information management system through the identification terminal to realize the binding of the identification code and the equipment. The equipment information management system stores basic information of the oil equipment, including key data such as equipment type, power, speed, flow, pressure, load, manufacturer, and equipment detection and inspection information, such as inspection records, maintenance records, inspection data, equipment rating, historical inspection details, inspector and auditor information; in addition, the equipment information management system also records equipment evaluation information, such as usage, safety status, etc., as well as comprehensive information such as operation and maintenance records, usage records and maintenance records. When it is necessary to query, add or delete equipment management information, the operator can use the identification terminal again to complete the work of oil equipment information management data collection, recording and storage by identifying radio frequency tags with different frequency bands and corresponding identification distances designed in the utility model.

[0052] Furthermore, the outer surface of the plastic top cover 2 has a groove, and the two-dimensional code recognition area 16 and the visual information display area 17 are both located in the groove, and the depth of the groove is less than 1 mm.

[0053] The edge of the notch of the tag installation slot 3 is provided with an inner ring sealing step 31, and the plastic top cover 2 is provided with an inner matching step 21 adapted to the inner ring sealing step 31, and the inner ring sealing step 31 and the inner matching step 21 together constitute an inner ring sealing structure. The utility model constructs a dustproof and waterproof barrier for the radio frequency electronic nameplate through the design of the inner ring sealing structure.

[0054] It should be noted that, in this embodiment, the plastic top cover 2 is the same size as the label installation groove 3 on the metal base 1, and the metal base 1 is installed on the petroleum equipment through the installation hole 8. The metal base 1 is preferably made of aluminum or stainless steel. The metal base 1 and the plastic top cover 2 can be connected by snap-fitting. In addition, in some embodiments, the metal base 1 can also be made by CNC machining, and the label installation groove 3 is milled out by a milling cutter. The plastic top cover 2 is a glue layer formed by epoxy resin glue potting. The epoxy resin glue is preferably a black colloid, so that a bright black area is formed on the surface of the plastic top cover 2. An annular boss is set at the edge of the notch of the label installation groove 3. The glue layer is fixed on the metal base 1 through the annular boss. The design of the annular boss limits the displacement of the glue layer, ensuring the stability and sealing of the glue layer after potting.

[0055] In the utility model, the number of mounting holes 8 is 1-2. When there are two mounting holes 8, the mounting holes 8 are symmetrically arranged at the opposite ends of the metal base 1; when there is one mounting hole 8, the mounting hole 8 is arranged at either end of the metal base 1. By passing the hanging rope through the mounting hole 8, the assembled radio frequency electronic nameplate can be hung on the petroleum equipment, realizing the hanging tag management of petroleum equipment such as wire ropes, medium pipelines, and containers.

[0056] Example 2

[0057] In order to enhance the protection performance against the NFC radio frequency tag 4 and the UHF radio frequency tag 5 , based on Example 1, this example adjusts and optimizes the sealing structure of the metal base 1 and the plastic top cover 2 .

[0058] like Figure 4-5 As shown, the edge of the metal base 1 is provided with an outer ring sealing step 10, and the inner surface edge of the plastic top cover 2 is provided with an outer matching step 20 that matches the outer ring sealing step 10. The outer ring sealing step 10 and the outer matching step 20 together constitute an outer ring sealing structure. This embodiment forms a double-layer sealing structure of this embodiment through the design of the outer ring sealing structure and the inner ring sealing structure described in Example 1, further improving the dustproof and waterproof performance of the radio frequency electronic nameplate of the utility model.

[0059] Furthermore, a countersunk hole 19 corresponding to the mounting hole 8 is provided on the plastic top cover 2 , and the metal base 1 and the plastic top cover 2 are fixed by bolts penetrating the mounting hole 8 and the countersunk hole 19 .

[0060] It should be noted that the difference from Example 1 is that the plastic cover 2 is the same size as the metal base 1; the countersunk hole 19 can be used to fix the plastic cover 2 to the metal base 1 in conjunction with the mounting hole 8, or the radio frequency electronic nameplate of the utility model can be fixed to the petroleum equipment by passing bolts through the countersunk hole 19 and the mounting hole 8. Of course, it can also be fixed in combination with double-sided foam glue 15 as described in Example 1.

[0061] like Figure 5 As shown, in order to improve the anti-collision performance, reinforcing ribs 18 are evenly distributed on the peripheral side of the plastic top cover 2.

[0062] Example 3

[0063] Based on the first embodiment, the structure of the label installation slot 3 is optimized in this embodiment.

[0064] At present, NFC radio frequency tags 4 and UHF radio frequency tags 5 are usually made of circular tags 13 and square tags 14 with basic shapes on the market, and the square tags 14 include square tags and rectangular tags. In order to adapt to these basic-shaped tags on the market, and perform standardized assembly.

[0065] like Figure 6-9 As shown, the tag installation slot 3 is provided with a limiting structure 12 that is respectively adapted to the NFC radio frequency tag 4 and the UHF radio frequency tag 5. The limiting structure 12 includes a special-shaped limiting structure 11 that limits the circular tag 13 and the square tag 14. Specifically, as Figure 6 As shown, there are two groups of special-shaped limiting structures 11, which are symmetrically fixed in the label installation groove 3.

[0066] Figure 7-9 A schematic diagram is shown of a circular label 13 and a square label 14 being assembled in a special-shaped limiting structure 11. It should be noted that the special-shaped limiting structure 11 is not limited to being assembled with circular labels 13 or square labels 14 at the same time, but can also be assembled in combination with circular labels 13 and square labels 14.
