[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In some embodiments, such as Figure 1 and Figure 2 As shown, this application proposes a rail clamp fracture monitoring and acquisition terminal device, including several acquisition terminals 100 installed on rail 001 and clamp 002. The acquisition terminal 100 includes a box body 101, a box cover 102, a controller 103, an acquisition device 105 and a permanent magnet 107. The top of the box body 101 is detachably provided with a box cover, and the controller 103 is installed inside it. The acquisition device 105, which is electrically connected to the controller 103, is installed on the outer wall. The permanent magnet 107 is fixedly embedded in the groove at the bottom of the acquisition device 105. The permanent magnet 107 can be magnetically installed on the rail 001 and clamp 002 to be detected.

[0029] The housing 101, serving as a sealed container for components such as the controller 103, can be manufactured using an aluminum alloy die-casting process, with an anodized surface treatment to enhance weather resistance. The cover 102 is a detachable sealing component, forming a waterproof structure with the housing 101 via a sealing ring. The controller 103, as a data processing unit, can employ a conventionally known embedded microprocessor to perform signal analysis functions. The permanent magnet 107 uses a high-energy magnet, such as neodymium iron boron, and its magnetic attraction stability is ensured by a grooved limiting structure.

[0030] The data acquisition unit 105 is a linear sensor used for fracture monitoring, deployed longitudinally along the clamping plate. Specifically, it uses a single enameled copper-clad aluminum wire, one end of which is electrically connected to the controller 103 inside the housing 101. The other end is arranged along the length of the rail 001 and clamping plate 002 on the clamping plate or rail, then folded back to connect to the controller 103, forming a detection loop. A layer of protective adhesive is applied to the data acquisition unit 105 for protection and fixation. In use, when the rail or clamping plate breaks, the copper wire breaks along with it. By monitoring the fracture of the copper wire, real-time fracture monitoring of the rail 001 or clamping plate 002 is achieved.

[0031] Specifically, the housing 101 and the cover 102 are connected by screws to form a sealed space, and the controller 103 continuously receives monitoring data from the data acquisition unit 105. When the rail 001 or the clamping plate 002 breaks, the corresponding data acquisition unit 105 detects the sudden strain signal and sends it to the controller 103, which then sends an alarm message via the wireless module 106. The permanent magnet 107 is embedded in a groove at the bottom of the housing 101, and the device is fixed to the surface of the rail 001 and the clamping plate 002 by magnetic attraction, eliminating the need for drilling or welding during installation.

[0032] Through the above technical solution, this application achieves automated monitoring of rail clamp fractures, eliminating the time blind spots of manual inspections. The use of magnetic, non-intrusive installation avoids damage to the track structure, and the modular design of each structure in the data acquisition terminal 100 improves equipment maintenance efficiency. Real-time data acquisition and transmission effectively prevents safety accidents caused by fractures, adapting to the long-term monitoring needs of complex railway operating environments.

[0033] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, this application further proposes a square box structure with an open top for the housing 101, with its four top corners sealed to the cover 102 using screws. The square box structure is a container with a regular geometric shape, which can be achieved by stamping metal sheets. The open top of the housing 101 facilitates the installation and maintenance of internal electronic components. The sealed connection refers to the installation of a sealing element at the joint surface between the housing 101 and the cover 102, such as using a silicone sealing ring embedded in the groove at the top edge of the housing 101. Under pressure, the sealing ring fills the microscopic gap between the housing and the cover, forming a continuous sealed interface, preventing rainwater from seeping into the internal circuitry along the seam, and improving the outdoor service life of the data acquisition terminal 100.

[0034] Specifically, both the box body 101 and the lid 102 are made of aluminum, aluminum alloy, or stainless steel, and the connection is sealed with a sealing ring. Aluminum, aluminum alloy, or stainless steel are all metal materials with corrosion-resistant properties; 6061 aluminum alloy or 304 stainless steel can be used, and their surfaces can be oxidized or passivated to enhance weather resistance. The sealing ring is an elastic sealing element, which can be made of nitrile rubber or fluororubber, and fills the assembly gap between the box body 101 and the lid 102 through compression deformation.

[0035] like Figure 2 and Figure 6 As shown, this application further proposes that grooves are respectively formed at both ends of the bottom of the box body, and permanent magnets 107 are fixedly embedded in the two grooves. The grooves refer to recessed structures at both ends of the bottom of the box body 101 for accommodating the permanent magnets 107. Specifically, regular-shaped grooves can be formed at the bottom of the box body by machining or molding, and the depth of the grooves matches the thickness of the permanent magnets to achieve embedding and fixation. Fixed embedding refers to fixing the permanent magnets 107 inside the grooves by physical restraint. Specifically, adhesive filling or pressing processes can be used to make the permanent magnets in close contact with the inner wall of the grooves, preventing displacement of the permanent magnets 107 in a vibrating environment.

[0036] like Figure 2 and Figure 6 As shown, this application further proposes that the data acquisition terminal 100 also includes a power module 104 installed inside the housing 101. The power module 104 is electrically connected to the controller 103 and the data acquisition unit 105. The power module 104 is a component used to provide electrical energy for the operation of the device. Specifically, it can be implemented using a built-in battery, an external power supply interface, or a wireless charging unit. Its function is to provide continuous power support for the controller 103 and the data acquisition unit 105.

[0037] Specifically, the power module 104 is integrated into the internal cavity of the housing 101, forming a closed circuit with the controller 103 and the data collector 105 via wires. When the device is installed on the rail 001 and the clamping plate 002, the power module 104 obtains power through its built-in battery or an external power supply interface and transmits the power to the controller 103 and the data collector 105. The power module 104 is rationally installed inside the housing 101, maintaining a compact layout with the controller 103 and other components. To meet the power supply requirements of the data acquisition terminal 100 in different scenarios, this application further proposes a lithium-ion battery for the power module 104, using a rechargeable or disposable battery to provide power to the device, eliminating dependence on external power sources.

[0038] like Figure 3 , Figure 4 and Figure 5As shown, this application further proposes that the data acquisition terminal 100 also includes an antenna module 106 disposed on the housing 101, and the antenna module 106 is electrically connected to the controller 103. The antenna module 106 is a hardware unit for wireless signal transmission and reception, which can be implemented using a patch antenna or a ceramic antenna. It establishes a data interaction channel with the controller 103 through a radio frequency circuit. The antenna module 106 is integrated and installed on the housing 101, and is connected to the communication interface of the controller through internal wiring to ensure the stability of signal transmission. In use, the controller 103 converts the fracture monitoring data acquired by the data acquisition device into a wireless signal format, and sends it to the external calibrator 200 via the antenna module 106.

[0039] Furthermore, this application proposes that the data acquisition terminal 100 is electrically connected to a calibrator 200 installed on the rail 001 and the clamp 002 via an antenna module 106. Multiple calibrators 200 are electrically connected to a concentrator, which can transmit the data acquired by the data acquisition terminal to the concentrator. The concentrator then connects wirelessly to the railway operation network data platform to achieve centralized processing of large data.

[0040] The calibrator 200, acting as a data relay node deployed on rail 001 and clamp 002, uses conventionally known data relay equipment. Its function is to establish a wireless communication link with the acquisition terminal 100, receiving and forwarding monitoring data to the concentrator. The antenna module 106 forms a bidirectional transmission channel with the calibrator 200 via a wireless communication protocol. The acquisition terminal 100 processes the rail clamp status data acquired by the acquisition unit 105 through the controller 103, and then sends it to the calibrator 200 via the antenna module 106.

[0041] The calibrator 200 and the concentrator establish a connection via wired or wireless communication. The acquisition terminal 100 transmits the rail clamp fracture monitoring data wirelessly to the calibrator 200. The calibrator 200 encapsulates the received data according to a preset protocol and forwards it to the concentrator. The concentrator aggregates the data from calibrators at different locations and performs preprocessing operations such as data format unification and redundancy filtering. The processed data is then uploaded to the railway operation network data platform. This process avoids the integration difficulties caused by inconsistent transmission paths of scattered data and reduces the delay of manual intervention.

[0042] The railway operation network data platform refers to the central data platform that stores railway operation status information. Its function is to provide a standardized access channel for monitoring data and to integrate and analyze the received monitoring data. Specifically, it can be implemented using a distributed computing framework or a cloud computing platform.

[0043] The rail joint fracture monitoring system, which consists of the data acquisition terminal 100, calibrator 200, concentrator, and railway operation network data platform as described in this application, solves the problem of scattered and isolated rail joint fracture monitoring data that cannot be integrated in real time. It achieves seamless connection between monitoring data collection from the terminal and analysis in the cloud, providing railway operation and maintenance departments with cross-regional and all-time fracture risk early warning support, reducing the probability of missed detection and shortening emergency response time.

[0044] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
