[0025] Please refer to Figure 1The present embodiment provides a data transmission device, including a core board 1, a communication board group, a communication interface 2 and an expansion board 3, wherein the core board 1 is detachably arranged on the expansion board 3, the communication interface 2 is fixed on the expansion board 3, the communication board group includes at least two communication boards 4, each communication board 4 is configured with a communication module supporting different communication protocols, the core board 1 and the communication interface 2 are communicatively connected through any communication board 4, and the communication board 4 used for communication connection is detachably connected to the core board 1 and the communication interface 2.
[0026] The data transmission device provided in this embodiment is, for example, a DTU. Since the communication board 4 adopts a detachable design, the communication module supporting different communication protocols can be replaced by replacing different communication boards 4, so that the appropriate communication board 4 can be selected according to the communication protocol support requirements of the device to expand the application occasions of the data transmission device. In addition, a detachable design is adopted between the core board 1 and the expansion board 3, and more functional modules can be designed on the expansion board 3 to realize the functional expansion of the data transmission device.
[0027] As a preferred example in this embodiment, the communication interface 2 configured on the expansion board 3 is a universal interface used for communication connection with various external devices. By replacing different communication boards 4, the data transmission device can support RS485, RS232 or other existing protocols.
[0028] Preferably, the expansion board 3 is also provided with an RJ45 communication interface 5 for accessing a network cable and adapting to a device of the TCP communication protocol. Of course, in addition to this, more types of communication interfaces 2 can be configured according to functional requirements, and the present invention does not limit this.
[0029] In this embodiment, the communication interface 2 and the RJ45 communication interface 5 can be fixed on the expansion board 3 by welding.
[0030] In this embodiment, the core board 1 and the expansion board 3 are communicatively connected via a first board-to-board connector. It should be noted that the first board-to-board connector is a conventional board-to-board connector in the prior art, and the first board-to-board connector includes a male socket and a female socket for communication connection, one of which is arranged on the core board 1, and the other is arranged on the expansion board 3.
[0031] Optionally, the core board 1 is a single piece, on which a variety of existing functional modules are arranged, such as a main control module, a data acquisition module, a cache module, and a data upload module, etc., and the expansion board 3 can be a single piece or multiple pieces, and the utility model does not limit this. Different functional modules can be arranged on the expansion board 3 according to needs, such as a communication management module, a data processing module, etc. It should be noted that the core board 1 and the expansion board 3 and the various modules thereon are all known technologies, and the utility model does not involve the improvement of computer programs.
[0032] Preferably, a plurality of limiting components 6 are provided on the expansion board 3, and the limiting components 6 are used to limit the core board 1 on the expansion board 3. As the name implies, the limiting components 6 mainly play a limiting role and are used to assist in fixing the core board 1. It should be understood that although the core board 1 and the expansion board 3 are connected through the first board-to-board connector, the stability of this connection method is not enough. Since the data transmission device is a mobile device, the core board 1 can be limited by additionally arranging limiting components 6, which can improve the connection stability between the core board 1 and the expansion board 3.
[0033] As a preferred example in this embodiment, Figure 2 As shown, the limiting component 6 includes a supporting portion 61 and a deformable extruding portion 62, wherein the supporting portion 61 is located below the extruding portion 62 and is fixed on the expansion board 3, and the extruding portion 62 is pressed against the upper surface of the core board 1. With such a configuration, the extruding portion 62 can exert a downward force on the core board 1, so that the core board 1 is stably fixed on the expansion board 3.
[0034] In the present embodiment, the position-limiting component 6 is made of elastic alloy. In addition to having a certain elastic deformation capacity, the elastic alloy also has the advantages of good heat resistance and fatigue resistance, and is a better choice. A feasible implementation method is that the position-limiting component 6 can be fixed on the expansion board 3 first, such as welding and fixing, and then the core board 1 is installed on the expansion board 3 from top to bottom. In this process, the edge of the core board 1 will move from top to bottom and collide and squeeze with the extrusion portion 62 of the position-limiting component 6, so that the extrusion portion 62 is elastically deformed, and when the core board 1 moves downward from the upper part of the extrusion portion 62 to the bottom of the extrusion portion 62, the extrusion portion 62 restores its original shape under the action of its own elasticity, thereby being pressed on the upper surface of the core board 1. It should be understood that the height of the extrusion portion 62 on the expansion board 3 (i.e., the height of the support portion 61) should be equal to or slightly less than the edge thickness of the core board 1, so that the extrusion portion 62 can press the core board 1. Of course, in addition to adopting elastic alloys, other elastic materials can also be adopted, and the utility model does not limit this.
[0035] The limiting component 6 can be fixed on the expansion plate 3 by welding, or by threaded connection or the like, and the present invention does not impose any limitation on this.
[0036] Preferably, there are at least three limiting components 6 and they are distributed at the peripheral edge of the core board 1. If there is only one or two limiting components 6, the force applied to the core board 1 is relatively limited. Considering the connection stability problem between the core board 1 and the expansion board 3, three or more limiting components 6 can be used. When three limiting components 6 are used, the three limiting components 6 can be arranged in a triangle, that is, the connection line of the three limiting components 6 constitutes a triangle, and the stability principle of the triangle is used to achieve a better limiting effect. If more than three limiting components 6 are used, such as the limiting components 6 are 4, it can be considered to arrange the limiting components 6 in a uniformly distributed manner along the peripheral edge of the core board 1, or two can be fixed to the two ends of the core board 1 in pairs, and a better limiting effect can also be achieved.
[0037] In this embodiment, there are three limiting components 6 , two of which are arranged at one end of the core board 1 , and another limiting component 6 is arranged at the other end of the core board 1 .
[0038] In this embodiment, one end of the communication board 4 for communication connection is connected to the core board 1 through the second board-to-board connector, and the other end is connected to the communication interface 2 through the third board-to-board connector. Similar to the first board-to-board connector, the second board-to-board connector and the third board-to-board connector both include a male socket and a female socket for communication connection, one of the male socket and the female socket of the second board-to-board connector is arranged on the communication board 4, and the other is arranged on the core board 1, and one of the male socket and the female socket of the third board-to-board connector is arranged on the communication board 4, and the other is arranged on the communication interface 2.
[0039] Preferably, the communication board 4 is a flexible circuit board on which a communication module is arranged. The communication module is, for example, an RS485 chip circuit or an RS232 chip circuit. By replacing different communication boards 4, the data transmission device can be adapted to different communication protocols.
[0040] Preferably, the expansion board 3 is provided with a power module, the power module is used to power the expansion board 3 and the core board 1, and the power module has a power interface and a battery interface 7. In the present embodiment, the power interface includes a power adapter interface 8 and a direct current power interface 9 directly connected to 5-35V, and the data transmission device has three power supply modes, the first mode is to connect the power adapter using the power adapter interface 8 for power supply, the second mode is that if there is no place to plug the power adapter on site, it is possible to plug the direct current from other devices in parallel to the direct current power interface 9, and the third mode is to access a battery (such as a lithium battery) using the battery interface 7 for power supply. Preferably, when the lithium battery and the power supply are accessed at the same time, the lithium battery will be automatically charged, and the lithium battery will automatically take over the device power supply when the power supply is disconnected, so as to realize the function that the device can still run after power failure, to prevent the sudden power failure on site.
[0041] In this embodiment, the data transmission device further includes a box body and a cover plate, wherein the core board 1, the communication board 4 and the expansion board 3 are all located in the box body, and the cover plate can be opened and closed on the box body. The box body is mainly used for packaging to prevent the core board 1, the communication board 4 and the expansion board 3 from being directly exposed to the external environment. Preferably, the cover plate can be connected to the box body by means of threaded connection, hinged connection, snap connection, etc., to realize the opening and closing function.
[0042] In summary, the embodiment of the utility model provides a data transmission device. Since the communication board adopts a detachable design, the communication module supporting different communication protocols can be replaced by replacing different communication boards, so that the corresponding communication board can be selected according to the communication protocol support requirements of the device to expand the application occasions of the data transmission device. In addition, the core board and the expansion board adopt a detachable design, and more functional modules can be designed on the expansion board to realize the functional expandability of the data transmission device.

For any technician familiar with the art, without departing from the scope of the technical solution of the present invention, the above disclosed technical content can be used to make many possible changes and modifications to the technical solution of the present invention, or modified into equivalent embodiments of equivalent changes.
