[0012] Figure 2 This is the top view of the present utility model.

[0013] Figure 3 This is the structural diagram of the support body of the present utility model.

[0014] Among them, 1 is the support body, 2 is the passive positioning beacon, 3 is the horizontal main board, 4 is the support board, 5 is the fixed seat, 6 is the first base board, 7 is the second base board, and 8 is the hollow. Specific implementation mode

[0015] Embodiment 1: A support for a passive positioning beacon 2, as Figure 1 and Figure 3 shown, includes a support body 1 with a "convex" - shaped structure. The passive positioning beacon 2 is fixed on the support body 1, and the lower part of the support body 1 is fixedly connected to the support base. The support body 1 includes a horizontal main board 3, and both ends of the horizontal main board 3 are fixedly connected to support boards 4 that extend downward and bend, and the bottom ends of the support boards 4 are fixedly connected to a fixed seat 5 that extends horizontally.

[0016] The passive positioning beacon 2 is an information carrier used to transmit signals in radio communication. It can be regarded as a passive device, that is, it does not actively emit signals but uses external signal sources (such as radio waves, radar signals, etc.) to work.

[0017] The working principle of the passive positioning beacon 2 is mainly based on signal reception and signal processing. When signals emitted by external signal sources (such as radar, communication equipment, etc.) reach the passive positioning beacon 2, the beacon will receive these signals and perform processing such as amplification, attenuation, phase modulation, and encoding on the signals through an internal processing mechanism to extract information about the target position. This information can then be used to locate the position of the target.

[0018] The passive positioning beacon 2 can be divided into various types according to its structure and function, including but not limited to conventional positioning beacons, passive positioning beacons, etc. These beacons are usually composed of components such as antennas and receivers and are used to receive and process external signals.

[0019] The passive positioning beacon 2 has a wide range of applications in multiple fields. In the military field, it can be used for tasks such as reconnaissance and missile guidance; in the maritime and aviation fields, it can be used for precise navigation and positioning; in the civilian field, such as in an underground container transportation system, the passive beacon can be excited by the electromagnetic waves emitted by the vehicle antenna and transmit absolute position information to the vehicle, thereby realizing the vehicle positioning function.

[0020] The passive positioning beacon 2 has advantages such as strong concealment, strong anti - interference ability, and wide application range. Since it does not need to actively emit signals, it has extremely strong concealment when performing positioning tasks and is not easily detected and interfered with by the enemy. At the same time, since it uses the signals naturally existing in the environment for positioning, it can be applied in a wider area.

[0021] Although the passive positioning beacon 2 has many advantages, it also has certain limitations. For example, its positioning accuracy and stability largely depend on the external signal environment, such as the complexity of the electromagnetic environment and the signal strength. In addition, to achieve high-precision positioning, complex algorithms and data processing technologies need to be adopted, which require high performance of hardware and software, so the cost is relatively high.

[0022] Therefore, when installing the passive positioning beacon 2, it is necessary to minimize the impact on the original structure and function of the sleeper, and accurately calculate and adjust the distance and angle between the passive positioning beacon 2 and the vehicle to ensure the stability and accuracy of signal transmission. At the same time, railway sleepers, also known as crossties, are a kind of railway fittings. Their main function is to support the rails, maintain the position of the rails, and evenly distribute the huge pressure transmitted by the rails on the roadbed. The sleeper needs to bear the load, lateral force and longitudinal horizontal force transmitted by the rails and evenly distribute them on the roadbed. The sleeper connects the two rails together, fixes the position of the rails, keeps a certain distance (gauge) between them, and at the same time fixes the railway direction to prevent longitudinal and lateral displacement due to the action of force. Railway sleepers are an indispensable part of the railway system, and their performance and quality are directly related to the safe and stable operation of the railway. Therefore, when installing the passive positioning beacon 2 on the railway sleeper, it must be noted that the impact on the original structure and function of the sleeper should be minimized as much as possible, and at the same time, the distance and angle between the passive positioning beacon 2 and the vehicle need to be accurately calculated and adjusted to ensure the stability and accuracy of signal transmission. Therefore, there are high requirements for the bracket of the passive positioning beacon 2.

[0023] As a further improvement of the present utility model, the bracket base is integrally fixed under the railway sleeper, and the bracket main body 1 is of an integrated design. The horizontal main board 3, the support board 4 and the fixed seat 5 are connected as a whole. The integrated structure design of the bracket main body 1 ensures the structural strength while facilitating production, processing and installation.

[0024] As a further improvement of the present utility model, the bracket base includes a first base plate 6 and a second base plate 7. The two ends of the first base plate 6 and the second base plate 7 are fixedly connected to the fixed seats 5 at both ends of the bottom of the bracket main body 1 through bolts. When installing, the first base plate 6 and the second base plate 7 are first fixed under the sleeper, and the split bracket base is more convenient to install.

[0025] As a further improvement of the present utility model, as Figure 2 shown, bolt holes are provided on the horizontal main board 3, and the passive positioning beacon 2 is fixed on the upper surface of the horizontal main board 3 through bolts.

[0026] As a further improvement of the utility model, a hollow 8 is provided in the middle of the support plate 4. After the bracket main body 1 and the bracket base are fixedly connected, they are clamped and fixed with the railway sleeper. The hollow 8 facilitates padding a rubber with a certain thickness between the sleeper and the bracket of the passive positioning beacon 2 during installation, ensuring that the bracket of the passive positioning beacon 2 can tightly hold the sleeper. In addition, according to actual needs, the installation height of the bracket of the passive positioning beacon 2 can be adjusted by adjusting the thickness of the rubber between the sleeper and the bracket, so as to ensure the stability and accuracy of signal transmission.

[0027] During installation, the support base needs to be fixed under the regular first. The split support base includes a first base plate 6 and a second base plate 7, both of which are long and thin sheet-like structures and can be easily inserted under the sleeper; then the integrated bracket main body 1 is covered on the sleeper, and the bracket main body 1 and the bracket base are fixedly connected by bolts; after the bracket main body 1 and the bracket base are fixedly connected, they are clamped and fixed with the railway sleeper. After the bracket main body 1 is installed, the passive positioning beacon 2 is fixed on the horizontal main board 3 of the bracket main body 1 by bolts.

[0028] Embodiment 2: A bracket for a passive positioning beacon 2, including a bracket main body 1 with a "convex" structure, the passive positioning beacon 2 is fixed on the bracket main body 1, and the lower part of the bracket main body 1 is fixedly connected with the bracket base. The bracket main body 1 includes a horizontal main board 3, and both ends of the horizontal main board 3 are fixedly connected with support plates 4 extending downward and bent, and the bottom ends of the support plates 4 are fixedly connected with a fixing seat 5 extending horizontally.

[0029] The passive positioning beacon 2 is an information carrier used to transmit signals in radio communication. It can be regarded as a passive device, that is, it does not actively emit signals, but works by using external signal sources (such as radio waves, radar signals, etc.).

[0030] The working principle of the passive positioning beacon 2 is mainly based on signal reception and signal processing. When signals emitted by an external signal source (such as a radar, a communication device, etc.) reach the passive positioning beacon 2, the beacon will receive these signals and perform processing such as amplification, attenuation, phase modulation, and encoding on the signals through an internal processing mechanism to extract information about the target position. This information can then be used to locate the position of the target.

[0031] The passive positioning beacon 2 can be divided into various types according to its structure and function, including but not limited to conventional positioning beacons, passive positioning beacons, etc. These beacons are usually composed of components such as antennas and receivers and are used to receive and process external signals.

[0032] Passive positioning beacons 2 have a wide range of applications in many fields. In the military field, they can be used for reconnaissance, missile guidance and other tasks; in the fields of navigation and aviation, they can be used for precise navigation and positioning; in the civilian field, such as underground container transportation systems, passive beacons can be excited by electromagnetic waves emitted by vehicle-mounted antennas and transmit absolute position information to vehicles, thereby realizing vehicle positioning functions.

[0033] The passive positioning beacon 2 has the advantages of strong concealment, strong anti-interference ability and wide application range. Since it does not need to actively transmit signals, it has extremely high concealment when performing positioning tasks and is not easily detected and interfered by the enemy. At the same time, since it uses the signals naturally existing in the environment for positioning, it can be applied in a wider area.

[0034] Although passive location beacons 2 have many advantages, they also have certain limitations. For example, their positioning accuracy and stability depend largely on the external signal environment, such as the complexity of the electromagnetic environment and the strength of the signal. In addition, in order to achieve high-precision positioning, complex algorithms and data processing technologies are required, which have high requirements on the performance of hardware and software, so the cost is relatively high.

[0035] Therefore, the passive positioning beacon 2 needs to be installed with minimal impact on the original structure and function of the sleeper, and the distance and angle between the passive positioning beacon 2 and the vehicle need to be accurately calculated and adjusted to ensure the stability and accuracy of signal transmission. At the same time, railway sleepers, also known as sleepers, are a type of railway accessories. Their main function is to support the rails, maintain the position of the rails, and evenly distribute the huge pressure transmitted by the rails on the roadbed. The sleeper needs to bear the load, lateral force and longitudinal horizontal force transmitted by the rails, and evenly distribute them on the roadbed. The sleeper connects the two rails together, fixes the position of the rails, keeps them at a certain distance (track gauge), and fixes the direction of the railway to prevent them from longitudinal and lateral displacement due to the force. Railway sleepers are an indispensable part of the railway system, and their performance and quality are directly related to the safety and stable operation of the railway. Therefore, when installing the passive positioning beacon 2 on the railway sleeper, it is necessary to pay attention to minimize the impact on the original structure and function of the sleeper. At the same time, it is necessary to accurately calculate and adjust the distance and angle between the passive positioning beacon 2 and the vehicle to ensure the stability and accuracy of signal transmission. Therefore, high requirements are placed on the passive positioning beacon 2 bracket.

[0036] As a further improvement of the present invention, the bracket base is fixed as a whole under the railway sleeper, the bracket body 1 is an integrated design, and the horizontal main board 3, the support plate 4 and the fixing seat 5 are connected as a whole. The integrated structural design of the bracket body 1 ensures the structural strength while facilitating production, processing and installation.

[0037] As a further improvement of the present utility model, the bracket base includes a first base plate 6 and a second base plate 7. Both ends of the first base plate 6 and the second base plate 7 are fixedly connected to the fixing seats 5 at both ends of the bottom of the bracket main body 1 by bolts. During installation, the first base plate 6 and the second base plate 7 are first fixed under the sleeper, and the split bracket base is more convenient to install.

[0038] As a further improvement of the present utility model, bolt holes are provided on the horizontal main board 3, and the passive positioning beacon 2 is fixedly connected to the upper surface of the horizontal main board 3 by bolts.

[0039] As a further improvement of the present utility model, a hollow 8 is provided in the middle of the support plate 4. After the bracket main body 1 and the bracket base are fixedly connected, they are clamped and fixed with the railway sleeper. The hollow 8 facilitates padding a certain thickness of rubber between the sleeper and the bracket of the passive positioning beacon 2 during installation to ensure that the bracket of the passive positioning beacon 2 can tightly hold the sleeper. In addition, according to actual needs, the installation height of the bracket of the passive positioning beacon 2 can be adjusted by adjusting the thickness of the rubber between the sleeper and the bracket, so as to ensure the stability and accuracy of signal transmission.

[0040] During installation, it is necessary to first fix the support base under the regular. The split support base includes a first base plate 6 and a second base plate 7, both of which are long and thin sheet-like structures and can be easily inserted under the sleeper. Then, the integrated bracket main body 1 is covered on the sleeper, and the bracket main body 1 and the bracket base are fixedly connected by bolts. After the bracket main body 1 and the bracket base are fixedly connected, they are clamped and fixed with the railway sleeper. During the installation process, a certain thickness of rubber is padded between the sleeper and the bracket of the passive positioning beacon 2 through the hollow 8 in the middle of the support plate 4 to ensure that the bracket of the passive positioning beacon 2 can tightly hold the sleeper, and the installation height of the bracket of the passive positioning beacon 2 is adjusted by adjusting the thickness of the rubber between the sleeper and the bracket, so as to ensure the stability and accuracy of signal transmission.
