Description

Technical Field

[0001] The utility model belongs to the technical field of electronic tags, and in particular relates to an anti-interference RFID electronic tag. Background Art

[0002] Currently, RFID (Radio Frequency Identification), also known as wireless radio frequency identification, is a communication technology that can read information stored in devices such as electronic tags or write information into devices such as electronic tags through radio electromagnetic wave signals.

[0003] RFID tags are also widely used in railways. Due to the large number of devices and data involved in managing and inspecting railway catenary support information, it is difficult for humans to quickly distinguish them. Therefore, RFID chips are typically installed on the metal supports on both sides of the railway. These chips are read by readers to facilitate equipment maintenance and inspection, saving inspection time.

[0004] However, in practice, due to the complexity and diversity of railway system equipment, some equipment in distribution cabinets and transformers (traction substations) can generate electromagnetic interference with electronic tags during operation. Interference often causes signal distortion and data reading errors in electronic tags, hindering the proper management of railway system equipment. Utility Model Content

[0031] The present invention will be described in detail below with reference to specific implementation methods.

[0032] like Figure 1 、 2 As shown in FIG. 3 , the present invention includes a housing 2 and a supporting plate 4 . A tag body 1 is disposed in the housing 2 , and a main antenna 11 is disposed on the top surface of the tag body 1 . The tag body 1 is connected to the housing 2 , and a socket 21 is provided on the side of the housing 2 .

[0033] like Figure 5 As shown, the auxiliary antenna 61 is electrically connected to a connector 62, and the auxiliary antenna 61 is connected to a mounting plate 6; the auxiliary antenna can adjust the operating frequency of the tag body through the connector to avoid interference frequency bands and improve the accuracy of data reading; it not only improves the anti-interference ability of the electronic tag, but also greatly enhances its practicality and reliability, thereby facilitating the normal management of railway system equipment.

[0034] like Figure 3 、 4As shown, a placement slot 41 and a through hole 43 are provided on the supporting plate 4. The through hole 43 is connected to the placement slot 41. The mounting plate 6 and the auxiliary antenna 61 are both arranged in the placement slot 41. The mounting plate 6 and the supporting plate 4 are detachably connected.

[0035] The supporting plate 4 is inserted into the socket 21, and the connector 62 is electrically connected to the tag body 1 to realize the frequency range change of the tag body 1; an auxiliary antenna of the required frequency is set on the mounting plate, and the mounting plate is inserted into the placement slot to facilitate the replacement of the mounting plate and the replacement of the auxiliary antenna.

[0036] like Figure 6 As shown, the support plate 4 is connected to a fixing assembly 5, which is used to fix the mounting plate 6. The connecting member 62 passes through the through hole 43 and abuts against the tag body 1, thereby achieving an electrical connection between the connecting member 62 and the tag body 1. When the mounting plate is placed in the placement slot, the spring is compressed, and the fixing plate will be tightly abutted against the mounting plate under the elastic force of the spring, thereby ensuring the fixing of the mounting plate.

[0037] like Figure 7 As shown, the fixing component 5 is arranged on the side of the placement groove 41 close to the through hole 43. The fixing component 5 includes a spring 51 and a fixing plate 52. The supporting plate 4 is provided with a fixing groove 42 connected to the placement groove 41. The first end of the spring 51 is arranged in the fixing groove 42 and is connected to the supporting plate 4. The second end of the spring 51 extends into the placement groove 41. The fixing plate 52 is arranged in the placement groove 41 and is connected to the spring 51. The top surface of the fixing plate 52 abuts against the mounting plate 6 to fix the mounting plate 6.

[0038] Connector 62 is curved and V-shaped. One end of connector 62 is connected to auxiliary antenna 61, while the other end is spaced apart from auxiliary antenna 61. The curved portion of connector 62 is farthest from auxiliary antenna 61 and abuts against tag body 1. When mounting plate 6 is inserted into the placement slot, connector 62 deforms slightly, allowing the mounting plate and auxiliary antenna to enter the slot smoothly and facilitating the removal of the mounting plate. Once the mounting plate is fully inserted into the slot, the connector returns to its original shape and can contact the auxiliary antenna. The curved connector minimizes wear on the support plate.

[0039] A protrusion 7 is fixedly connected to the inner wall of the housing 2. A sliding hole 44 is formed in the support plate 4. The protrusion 7 extends into the sliding hole 44 and slides into contact with the mounting plate 6. The end of the protrusion 7 facing away from the housing 2 is hemispherical. When the protrusion abuts the mounting plate, it further stabilizes the connection between the connector and the main antenna, improving signal transmission stability. This sliding contact between the protrusion and the mounting plate ensures smooth sliding while minimizing damage from collisions.

[0040] The shell 2 is filled with a rubber layer 8, which has insulating properties and further reduces the possibility of interference with the tag body by other devices.

[0041] The outer wall of the housing 2 is connected to a connection layer 3, which is a magnetic or adhesive structure and is used to fix the electronic tag to the metal support. The connection layer facilitates the fixing of the electronic tag to the external device without the need for additional tools.

[0042] The operating principle of this utility model is as follows:

[0043] The mounting plate 6 with the auxiliary antenna 61 and connector 62 is inserted into the placement slot 41, with the mounting plate 6 positioned on the side of the fixing plate 52 away from the spring 51. Once the mounting plate 6 is fully inserted into the placement slot 41, the spring 51 and fixing plate 52 cooperate to secure the mounting plate 6. Simultaneously, the connector 62 passes through the through-hole 43 and contacts the main antenna 11, establishing an electrical connection between the auxiliary antenna 61 and the main antenna 11. This adjusts the operating frequency of the tag body 1 to avoid interfering frequency bands and improves data reading accuracy. This improves the electronic tag's anti-interference capability, while enhancing its practicality and reliability, further facilitating the proper management of railway system equipment.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
