In this embodiment, a load sensor for detecting the load of the track fastener is integrated in the elastic pad under the track fastener, and the data acquisition device for track monitoring can be connected to the load sensor via a data line and obtain the load signal data measured by the load sensor.

[0027] Figure 1 is a three-dimensional diagram of the track monitoring data acquisition device in this embodiment, Figure 2 is a side view of the track monitoring data acquisition device in this embodiment, Figure 3 It is a structural exploded diagram of the track monitoring data acquisition device in this embodiment.

[0028] like Figures 1 to 3 As shown, the data acquisition device 100 for track monitoring includes an acquisition storage device 10 and a power supply device 20. The acquisition storage device 10 is used to obtain the load data measured by the load sensor, store the load data, and further transmit the load data to other devices. The power supply device 20 is used to supply power to the acquisition storage device 10.

[0029] Figure 4 It is a three-dimensional diagram of the acquisition and storage device in this embodiment.

[0030] As Figures 1 to 4 shown, the acquisition and storage device 10 includes a first housing 11, an antenna 12, and two modular circuit boards disposed in the first housing 11.

[0031] Among them, the first housing 11 is generally rectangular in shape and is assembled by a first upper housing 111 and a first lower housing 112. Both the first upper housing 111 and the first lower housing 112 are plate-shaped with two bending portions, and their cross-sections are in a "U" shape. The side plates of the two are combined alternately to form a rectangular housing.

[0032] Among them, the first upper housing 111 includes an integrally formed top plate and two side plates perpendicular to the top plate. The two side plates are respectively connected to both sides of the top plate in the length direction, and the two side plates are parallel to each other. The two side plates are respectively an antenna mounting side plate 1111 and a snap-fit side plate 1112. A plurality of mounting holes matching the antenna 12 are provided on the antenna mounting side plate 1111 for mounting the antenna 12. A plurality of snap holes 1113 are provided on the snap-fit side plate 1112 for the power supply unit 20 to snap on. As Figure 4 shown, the snap hole 1113 includes a circular hole portion 1113a and a strip hole portion 1113b communicating with the circular hole portion 1113a. The strip hole portion 1113b extends along the length direction of the snap-fit side plate 1112, and the width of the strip hole portion 1113b is smaller than the diameter of the circular hole portion 1113a. In this embodiment, two snap holes 1113 are provided.

[0033] The first lower housing 112 includes an integrally formed bottom plate and two side plates perpendicular to the bottom plate. The two side plates are respectively connected to both sides of the bottom plate in the length direction, and the two side plates are parallel to each other. The two side plates are respectively an interface side plate 1121 and a heat dissipation side plate 1122. A plurality of interface holes 1121a are provided on the interface side plate 1121, and the shapes and positions of the respective interface holes 1121a correspond to the shapes and positions of the interfaces on the main board disposed inside the housing, so that the corresponding interfaces can be exposed outward from the interface side plate 1121. A plurality of heat dissipation holes 1122a are provided on the heat dissipation side plate 1122. In this embodiment, the heat dissipation holes 1122a are a row of circular through holes.

[0034] The antenna 12 is used to implement 4G or 5G communication with other external devices.

[0035] The two modular circuit boards include a collection main board 13 and a storage service main board 14, which are connected by plugging data cables. The collection main board 13 is used to collect the load signal data measured by the load sensor 200, and the storage service main board 14 is used to store the load signal data collected by the collection main board 13, and can be used to further transmit the load signal data to other external devices 300.

[0036] The acquisition main board 13 includes an acquisition board main control module (FPGA), an acquisition board power conversion module, a signal acquisition module, a signal processing module and a signal transmission module.

[0037] The acquisition board power conversion module is used to convert the voltage provided by the power supply device 20 into a stable operating voltage and supply it to other modules. The acquisition board power conversion module has a power interface for electrically connecting to the power supply device 20. In this embodiment, the power interface is provided with an EMI filter.

[0038] The signal acquisition module has a signal line interface 131, and the signal line interface 131 is connected to the load sensor through a sensor signal line, so that the load signal data measured by the load sensor can be collected from the load sensor.

[0039] The signal processing module is used to perform signal processing on the collected load signal data.

[0040] The signal transmission module is used to transmit the processed load signal data to the storage service mainboard 14. In this embodiment, the signal transmission module is a serial communication module having a signal interface, and the signal interface is provided with an EMI filter.

[0041] The acquisition mainboard 13 needs to isolate the interference of the common ground and the external electromagnetic interference, so EMI filters are set at its power interface and signal interface. In addition, the acquisition mainboard 13 adopts FPGA, the process requirements are relatively low, and the wiring on the board is relatively not very complicated.

[0042] The storage service mainboard 14 includes a storage board main control module (CPU), a storage board power conversion module, a signal receiving module, a storage module and at least one external communication module.

[0043] The storage board power conversion module is used to convert the voltage provided by the power supply device 20 into a stable operating voltage and supply it to other modules. The storage board power conversion module has a power interface for electrically connecting to the power supply device 20.

[0044] The signal receiving module is used to receive the collected and processed load signal data from the acquisition mainboard 13. In this embodiment, the signal receiving module is also a serial communication module, having a signal interface, which is connected to the signal interface on the acquisition mainboard 13 through a data line.

[0045] The storage module includes one or more memories for storing (temporarily) the load signal data received by the signal receiving module.

[0046] The external communication module is used to communicate with other external devices 300. In this embodiment, there are multiple external communication modules, including an Ethernet communication module, a USB communication module, and an RS485 communication module, which can communicate with other external devices in different ways to transmit the load signal data. Correspondingly, there are multiple external communication interfaces at the interface side plate 112, including an Ethernet interface 141, a USB interface 142, and an RS485 interface 143.

[0047] The storage service main board 14 operates in a high-frequency and high-temperature state, the circuit wiring on the board is relatively complex, and the process requirements for its CPU and memory are high.

[0048] That is to say, in this embodiment, the two templated main boards inside the acquisition and storage device 10 realize the complete functions of signal data acquisition, processing, and storage.

[0049] The above-mentioned modules can be implemented by using corresponding circuits or chips in the prior art.

[0050] In addition, the acquisition main board 13 is fixed on the bottom plate of the first lower housing 112 by multiple fixing members. The plane direction of the acquisition main board 13 is parallel to the plane direction of the bottom plate, and the fixing members leave a certain gap between the acquisition main board 13 and the bottom plate.

[0051] The storage service main board 14 is fixed on the interface side plate 1121 of the first lower housing 112 by multiple fixing members. The storage service main board 14 is located above the acquisition main board 13, with a certain distance between them, and the plane direction of the storage service main board 14 is also parallel to the bottom plate of the first lower housing 112. Each interface on the storage service main board 14 is aligned with the corresponding interface hole 1121a on the interface side plate 1121. In addition, the length and width dimensions of the storage service main board 14 are smaller than those of the acquisition main board 13.

[0052] Therefore, the first lower housing 112 fixed with the acquisition main board 13 and the storage service main board 14 can be disassembled to expose the two main boards outward, facilitating inspection and maintenance. Or, the first upper housing 111 can also be disassembled. Since the first upper housing 111 and the first lower housing 112 are made of plate members with a "U"-shaped cross-section, removing one of them can fully expose the two main boards.

[0053] The power supply device 20 includes a second housing 21 and a battery pack 22 disposed inside the second housing 21.

[0054] The second housing 21 is generally in the shape of a cuboid. The width and thickness of the second housing 21 are basically the same as those of the first housing 21 respectively, and the length of the second housing 21 is less than that of the first housing 21, being 1 / 3 to 1 / 2 of it.

[0055] The second housing 21 is assembled by a second upper housing 211 and a second lower housing 212. The first upper housing 211 and the first lower housing 212 are also in the shape of plates with two bending parts, and their cross-sections are in the shape of "凵". The side plates of the two are combined alternately to form a cuboid outer shell.

[0056] Among them, the second upper housing 211 includes a top plate formed integrally and two side plates perpendicular to the top plate. The two side plates are respectively connected to both sides in the length direction of the top plate, and the two side plates are parallel to each other. One of the side plates is a side plate 2111 for snap connection, and a plurality of snap connectors 211 are fixed on the outer surface of the side plate 2111 for snap connection. The positions of the plurality of snap connectors 211 respectively match the plurality of snap holes 1113. In this embodiment, there are two snap connectors 211.

[0057] Each snap connector 211 is in the shape of a button, including a cylindrical part 2111a fixed on the outer surface of the side plate 2111 for snap connection and a circular plate part 2111b coaxially formed at the outer end of the cylindrical part 2111a. The diameter of the circular plate part 2111b is larger than that of the cylindrical part 2111a and slightly smaller than the diameter of the circular hole part 1113 of the snap hole 1113; the diameter of the cylindrical part 2111a is basically equal to or slightly larger than the width of the strip hole part 1113b.

[0058] Therefore, with the side plate 2111 for snap connection of the power supply device 20 facing the side plate 1112 for snap connection and cooperation of the acquisition and storage device 10, align the plurality of snap connectors 211 with the circular hole parts 1113a of the plurality of snap holes 1113 respectively and insert the snap connectors 211 until the two side plates are substantially in contact, and then move the whole power supply device 20 along the extension direction of the strip hole part 1113b, so that the cylindrical part 2112a of the snap connector 211 is embedded into the end of the strip hole part 1113b, and the assembly of the power supply device 20 and the acquisition and storage device 10 can be completed. Similarly, the power supply device 20 can be disassembled by operating in the reverse order of the above operation sequence, and the operation is very convenient.

[0059] In use, the power supply device 20 with battery packs of different performances and different capacities can be disassembled, assembled and replaced according to actual needs, or another same power supply device 20 can be replaced when the power of the currently snapped power supply device 20 is exhausted.

[0060] The second lower housing 212 includes an integrally formed bottom plate and two side plates perpendicular to the bottom plate, the two side plates are respectively connected to both sides of the bottom plate in the length direction, and the two side plates are parallel to each other. One of the side plates is an outlet side plate 2121, which is provided with a threading hole 2121a, through which the power supply line 221 of the internal battery pack 22 passes.

[0061] Functions and Effects of the Embodiments

[0062] The data acquisition device for track monitoring provided in this embodiment includes an acquisition storage device and a power supply device, wherein the acquisition storage device uses an independent acquisition mainboard and storage service mainboard, so that the two mainboards can be designed, verified and manufactured according to their respective requirements. Compared with an integrated mainboard, the difficulty of the production process can be reduced, and the yield rate of the mainboard can be improved, thereby reducing the production cost and subsequent maintenance cost of the equipment. In addition, the power supply device can be detachably installed on one side of the acquisition storage device, so after the power of the power supply device is exhausted, another power supply device can be easily replaced, and power supply devices with different characteristics and different capacities can also be disassembled and replaced according to actual needs, so that the equipment can be conveniently applied to more environments and usage scenarios.

[0063] Specifically, the acquisition mainboard does not need to consider issues such as storage and further communication transmission. FPGA can be used to implement data acquisition functions and be designed for anti-interference requirements. Therefore, the wiring of the acquisition mainboard is relatively simple and the production process requirements are not high. Similarly, the storage service mainboard does not need to consider anti-interference issues. Therefore, compared with the integrated design, this design not only reduces the difficulty of development and production, but also improves the performance of the entire machine and facilitates subsequent maintenance work.

[0064] Furthermore, the two modular mainboards in the acquisition and storage device in the embodiment realize all the complete functions from signal data acquisition, processing to storage, and no additional processing modules, control modules, etc. are required, which is more convenient in actual use.

[0065] Furthermore, a snap-on hole is provided on the first shell of the acquisition storage device, and a corresponding snap-on piece is provided on the second shell of the power supply device, so the power supply device can be disassembled and replaced very conveniently without the need for special tools.

[0066] Furthermore, the first shell and the second shell are both in the shape of a rectangular parallelepiped, and the second shell is installed on one side of the length direction of the first shell and the width and thickness of the two are basically the same. Therefore, after installation, the overall device is also in the shape of a regular rectangular parallelepiped, with beautiful appearance and good integrity.

[0067] Furthermore, the length of the second housing is relatively short, which can make the lever arm from the fixed mounting point of the first housing to the center of gravity of the power supply device relatively short. Even if the battery pack is heavy, it is not easy to generate a large stress on the fixed mounting point of the acquisition and storage device, thus affecting its installation stability.

[0068] Furthermore, the first housing is assembled by two plate members (the first upper housing and the first lower housing) with a "U"-shaped cross-section, and the acquisition main board and the storage service main board are both fixed on the first lower housing. Therefore, removing one of the plate members can fully expose the two main boards outward, facilitating the inspection and maintenance of the two main boards.

[0069] Furthermore, multiple external communication interfaces of the acquisition and storage device are arranged at its side plate for interfaces, and the power supply output interface of the power supply device is arranged at the side plate of its output port. The side plate for interfaces and the side plate of the output port are located on the same side of the overall device, which facilitates wiring and maintenance.

[0070] Furthermore, the external communication interfaces of the acquisition and storage device include an Ethernet interface, a USB interface, and an RS485 interface. Therefore, it can be connected to external devices with various different interfaces, enabling the device to be applicable to more usage scenarios.

Those skilled in the art should understand that the present utility model is not restricted by the above embodiments.

[0072] For example, in the above embodiment, the data acquisition device for track monitoring is used to acquire the load data of track fasteners. In fact, this device can also be used in cooperation with other sensors in the track to realize the monitoring of other track components.

[0073] In the above embodiment, a card interface or a card slot is provided on the housing of the acquisition and storage device, and a corresponding hanging buckle is provided on the housing of the power supply device. In an alternative solution, other existing snap docking structures can also be adopted, or a hanging buckle or other types of fasteners can be provided on the housing of the acquisition and storage device, and a card interface or a card slot can be provided on the housing of the power supply device.
