[0026] Given the importance of rail shoes, we've developed a dedicated rail shoe positioning system to better manage and utilize them, ensuring safe and smooth railway operations. This system leverages modern technology to locate rail shoes in real time or over time. Using BeiDou, UWB, and wireless communications, it tracks the rail shoe's position in real time and records its movements, enabling management and monitoring.

[0027] The UWB+Satellite Fusion Iron Shoe Positioning Terminal (HXZK-TX) fusion positioning system combines the advantages of two positioning technologies, enabling more accurate and reliable positioning in various environments. UWB (ULtra-Wideband) technology and GNGSS (Global Positioning System) are two different wireless positioning technologies, each with unique advantages and limitations. By integrating these two technologies, a more accurate and reliable positioning solution can be achieved.

[0028] UWB is a short-range, high-precision wireless communication technology that achieves high-precision time measurement by sending and receiving extremely narrow pulse signals, thereby achieving precise positioning. UWB technology has the following characteristics

[0029] High precision: UWB can achieve centimeter-level positioning accuracy, which is suitable for application scenarios with extremely high precision requirements.

[0030] Low power consumption: UWB devices use short pulses to transmit data with a low duty cycle, thus consuming less power.

[0031] Strong anti-interference ability: Since the bandwidth of UWB signal is very wide, it has strong anti-interference ability against multipath effects.

[0032] High security: UWB signals have low power spectrum density and are difficult to intercept or interfere with other systems.

[0033] GNSS is a satellite-based global positioning system that can provide positioning services in open outdoor areas. The main features of satellite positioning technology include

[0034] Global coverage: The GNSS system consists of multiple satellites and can provide positioning services worldwide.

[0035] Portability: GNSS receivers are small and portable and can be easily integrated into various devices.

[0036] Real-time: GNSS can provide real-time positioning information, suitable for dynamic tracking and navigation.

[0037] Combining UWB and GNSS technologies can fully leverage their respective strengths to provide a more powerful and flexible positioning solution:

[0038] Seamless coverage: GNSS is suitable for open outdoor environments, while UWB is suitable for indoor environments or those with GNSS signal interference. The integration of the two can achieve seamless positioning coverage indoors and outdoors.

[0039] Improved accuracy: UWB's high-precision characteristics can compensate for the insufficient accuracy of GNSS in certain environments and improve overall positioning accuracy.

[0040] Enhanced reliability: When GNSS signals are blocked or interfered with, UWB can provide stable positioning information and enhance system reliability.

[0041] Expansion of application scenarios: Fusion positioning technology can be applied to more scenarios, such as indoor positioning, personnel tracking, security monitoring, etc.

[0042] The features of the equipment are as follows

[0043] High-precision positioning: Satellite positioning accuracy can reach 1 to 2 meters.

[0044] UWB technology: With an accuracy of up to 30 cm, it is very suitable for environments with weak or no GNSS signals.

[0045] Portability and Convenience: Lightweight and designed for iron shoe positioning use.

[0046] Multi-system compatibility: supports Beidou positioning system with global coverage.

[0047] Weather-resistant: Designed to withstand harsh weather conditions, with an IP67 rating.

[0048] Multiple communication methods: 4G / LORA UWB, LORA communication.

[0049] This device can be installed on an iron shoe: real-time positioning, reporting positioning once every 1 second by default (reporting time can be modified), static sleep: by default, the device enters sleep mode after being completely still for 2 consecutive minutes without moving. When activated again by movement (sleep time can be modified), the device sends a location message and the status bit is sleep state 2 Low battery alarm: when the battery is less than 10%, the power indicator flashes red, once per second.

[0050] At the same time, the positioning system architecture is as follows Figure 6 As shown, a wireless positioning base station is installed on site. The base station and the iron shoe positioning terminal (hereinafter referred to as the detection terminal) communicate through UWB signals, and then put the communication data into the server through 4G. The positioning engine software installed on the server processes the data after receiving it, and then calculates the real-time position of the terminal; when the terminal leaves the coverage area of the wireless positioning base station signal, it switches to satellite positioning mode, and the satellite positioning data sends the location data to the server through 4G. The positioning system platform installed on the server will display the terminal position in real time.

[0051] As a further solution of the present invention: the positioner 7 includes a screw 71 and a positioning pad 72, a screw hole 11 is opened inside the rail seat 1, the screw 71 is screwed into the screw hole 11, one end of the screw 71 is fixedly connected to the positioning pad 72, and the end of the positioning pad 72 away from the screw 71 is adapted to the railway track.

[0052] As a further solution of the present invention, a positioning pad cavity 12 is opened on one side of the screw hole 11 , and the positioning pad 72 is adapted to the positioning pad cavity 12 .

[0053] As a further solution of the present invention, an extension eave 5 is provided on one side of the track seat 1 , and the contact roller 6 is rotatably connected to the extension eave 5 .

[0056] As a further solution of the present invention: one side of the pad 3 is provided with a slope 31 , and one side of the track seat 1 and the wheel clamp seat 2 is provided with a handle 4 .

[0057] The working principle of the present utility model is as follows: since a wheel clamp seat 2 and a pad 3 movably connected to the circumference of a train wheel are fixedly installed on one side of the track seat 1, a contact roller 6 for contacting and moving the side of the railway track is provided inside the track seat 1, and a positioner 7 for locking the side of the railway track is provided inside the track seat 1.
