[0025] Some of the terms are explained below:

[0026] Explosion protection: Explosion protection refers to the ability to resist the impact force and heat of the explosion without any loss and still be able to work normally. To prevent the occurrence of explosions, three necessary conditions must be considered. If one of the necessary conditions is restricted, the occurrence of the explosion will be restricted.

[0027] Internet of Things: The Internet of Things refers to connecting any object to the network through information sensing devices according to agreed protocols. Objects exchange and communicate information through information dissemination media to achieve intelligent identification, positioning, tracking, supervision and other functions.

[0028] Gateway: Gateway is also called network connector or protocol converter. Gateway realizes network interconnection above the network layer. It is a complex network interconnection device and is only used for interconnection between two networks with different high-level protocols. Gateway can be used for interconnection between wide area networks and local area networks. Gateway is a computer system or device that performs the conversion task. It is used between two systems with different communication protocols, data formats or languages, or even completely different architectures.

[0029] Reference Figure 1 The embodiment of the present application provides an explosion-proof Internet of Things gateway, which specifically includes four parts: an installation base 100, a gateway mainboard 300, a visible part 400 and a locking part 200. It has few parts and is simple to manufacture. Correspondingly, it is also convenient to install.

[0030] Among them, the mounting base 100 and the locking part 200 are both made of metal, and the metal can be aluminum alloy and stainless steel, which has a certain structural strength and is not easy to rust. Specifically, the shape of the base 101 of the mounting base 100 can be cylindrical or prismatic, and there are no excessive restrictions here. The embodiment of the present application provides a quadrangular prism-shaped base 101, and of course the base 101 can also be other polygonal prisms. Among them, one end of the mounting base 100 has a cavity with one end open (not shown in the figure), and the gateway motherboard 300 is fixed in the cavity.

[0031] The visible portion 400 is made of a transparent material, and is close to the open end of the cavity. After one end of the visible portion 400 passes through the locking portion 200 close to the mounting base 100, the other end of the visible portion 400 is clamped in the locking portion 200. The locking portion 200 and the mounting base 100 are connected through a locking member so that the visible portion 400 covers the open end of the cavity. The locking and fixing of the visible portion 400 in this design makes installation more convenient and can also firmly fix the visible portion 400.

[0032] Compared with the existing Internet of Things gateways that are directly placed in the explosion-proof box, the explosion-proof Internet of Things gateway of the present application is completely designed, and the gateway mainboard 300 is provided with an explosion-proof and explosion-proof structure. Specifically, the structure of the mounting base 100 made of metal is more solid, and the explosion-proof and explosion-proof capability is strong. The gateway mainboard 300 placed therein can be effectively protected. The visible part 400 is locked and fixed to the open part of the cavity through the locking part 200 to achieve the sealing of the cavity, and the waterproof and dustproof sealing is achieved, which can effectively protect the gateway mainboard 300 located in the cavity. At the same time, the visible part 400 is made of transparent material, so that the working state of the gateway mainboard 300 is well displayed, and it does not affect the information collection and information transmission of the gateway mainboard 300. The overall structure is relatively simple. When the gateway mainboard 300 is found to be faulty, the locking part can be disassembled to achieve the maintenance of the gateway mainboard in the cavity, which is convenient for maintenance.

[0033] In the present application embodiment, Figure 5As shown, the gateway mainboard 300 includes a warning module 310 and an information processing module 320. The warning module 310 and the information processing module 320 are electrically connected. The warning module 310 is used to generate sound and / or light. Specifically, the warning module 310 displays the corresponding warning color light and sound according to the processing result of the information processing module 320. The information processing module 320 is used to collect information and / or transmit information, and further process the collected information. The information processing module 320 can transmit information by wire or wirelessly. Furthermore, a safety isolation circuit module 330 is also provided on the gateway mainboard 300. The safety isolation circuit module 330 mainly processes the non-intrinsically safe circuit and the communication through the isolation circuit so that the output signal circuit will not cause sparks and explosions in a flammable environment, thereby ensuring safety and reliability during use.

[0034] In some examples, such as Figure 4 As shown, the visible portion 400 includes a visible body 410, and the middle portion of the visible body 410 bulges in a direction away from the cavity to form a storage cavity 412. In the embodiment of the present application, the visible body 410 is cylindrical, and the end of the visible body 410 is an arc surface. The storage cavity 412 is provided to partially store the gateway motherboard 300 when the cavity space is insufficient, so as to achieve compatibility with gateway motherboards 300 of different models and sizes, and has stronger applicability.

[0035] Furthermore, a connecting portion 411 is provided on the side of the visible body 410 near the cavity, and the connecting portion 411 is embedded in the locking portion 200. When the locking portion 200 is connected to the mounting base 100 through the locking member, the connecting portion 411 is pressed against the mounting base 100 by the locking portion 200, thereby achieving a fitting connection between the connecting portion 411 and the mounting base 100.

[0036] Specifically, Figure 3 As shown, the middle part of the locking part 200 is formed with a hollow structure 220 adapted to the visible body 410, and the locking part 200 is provided with a groove 230 for the connecting part 411 to be embedded in one side of the mounting base 100. After the locking part 200 is connected to the mounting base 100, the connecting part 411 presses against the mounting base 100 under the action of the locking part 200 to complete the sealing of the cavity. This design completes the locking and fixing of the visible part 400, and also completes the sealing of the cavity to prevent water and dust.

[0037] In some examples, such as Figure 1 and Figure 2As shown, a docking portion 130 extends outward from the side of the mounting base 100. The arrangement of the docking portion 130 can reduce the amount of materials used in the manufacture of the mounting base 100, can effectively save costs, and can also reduce the weight of the mounting base 100. The docking portion 130 is circumferentially provided with a plurality of first locking holes 131 for the locking member to pass through, and the locking portion 200 is provided with a second locking hole 210 at a position corresponding to the first locking hole 131. After the locking member passes through the first locking hole 131 and the second locking hole 210 in sequence, the locking member fastens the locking portion 200 and the mounting base 100 together through a thread. The number of the first locking hole 131 and the second locking hole 210 is at least 4, so that the sealing connection between the visible portion 400 and the mounting base 100 can be effectively ensured after the locking portion 200 and the mounting base 100 are connected through the locking member. Of course, if it is not ensured whether it is completely sealed, a layer of sealant can be applied between the visible portion 400 and the mounting base 100.

[0038] like Figure 3 As shown, the locking body 201 of the locking portion 200 is a plate, and the second locking hole 210 is disposed at the edge of the locking body 201 .

[0039] In some other embodiments, screw holes may be directly provided on the mounting base 100, and then through holes may be provided on the locking portion 200, and the mounting base 100 and the locking portion 200 may be locked and fixed by screws, so that quick disassembly and connection can be achieved.

[0040] In the embodiment of the present application, the locking member includes a bolt and a nut, and the stud of the bolt passes through the first locking hole 131 and the second locking hole 210 and is threadedly connected with the nut. The assembly and disassembly is simple, and the connection is more secure.

[0041] In some examples, such as Figure 1 and Figure 2 As shown, at least two connecting ears 110 are also provided at the flat end of the side of the mounting base 100, and the connecting ears 110 extend in a direction perpendicular to the side of the mounting base 100, and the connecting ears 110 are arranged in a circumferential array with the center of the mounting base 100 as the center, so that the mounting base 100 can be fixed more firmly when it is fixed to a wall or other places. Furthermore, the connecting ears 110 have a U-shaped notch. When fixing, firstly, holes for screw fixing are punched at the positions corresponding to the U-shaped notches at the relevant positions, and then bolts are passed through the U-shaped notches to press the connecting ears 110 against them, so as to achieve the fixing of the mounting base 100.

[0042] In some examples, a plurality of wiring ports 120 are arranged circumferentially on the side of the mounting base 100, and the wiring ports 120 are connected to the cavity. The wiring ports 120 are designed to have threaded interfaces for installing sealing rings according to explosion-proof requirements, and the number is designed to be several as required. The wiring ports 120 are used for wired connection between other devices and the gateway mainboard 300. The wiring ports 120 are arranged on the side without affecting the installation of the mounting base 100.

[0043] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
