[0005] The front side of the industrial gateway in the above-mentioned prior art is provided with a plurality of connection interfaces for connecting with external devices to facilitate data acquisition and transmission in the later period. However, when the industrial gateway is not in use, the connection interfaces cannot be shielded and protected, so that dust and moisture from the outside can easily enter the connection interfaces, which may cause corrosion and damage to the metal parts in the connection interfaces, resulting in a decrease in the performance of the connection interfaces and affecting the use of the industrial gateway. Therefore, we propose an industrial gateway for data acquisition and transmission based on the Internet of Things and a protection system thereof to solve the problems mentioned above. SUMMARY

[0008] Preferably, the upper and lower sides of the gateway body are slotted to install limit control mechanisms. The limit control mechanism includes a limit slide rod with one end connected to the gateway body and in the shape of a "T". A reset spring is nested on the outside of the limit slide rod.

[0009] Preferably, the upper and lower connecting parts with a “7” shaped structure are respectively installed on the upper and lower sides of the protective cover. The upper and lower connecting parts are slidably connected with limit rods through them, and the inner sidewall of the protective cover is fitted with a rubber sealing gasket.

[0010] Preferably, the inner wall of the lower connector is fitted with an adsorption block made of magnetic material.

[0011] Preferably, the self-control component includes a vertical rod installed in a groove inside the bottom surface of the gateway body. A transmission gear is keyed to the upper outer side of the vertical rod, and two sets of self-push plates are symmetrically installed on the lower outer side of the vertical rod. A lower connecting piece is provided on the outer side of the self-push plate, and the two sets of lower connecting pieces move synchronously towards each other through the self-push plate.

[0012] Preferably, the front end of the "L"-shaped self-control rod is slidably inserted into a groove in the bottom surface of the gateway body. A rack body is fixed to one side of the front end of the self-control rod, and a transmission gear is meshed with the outer side of the rack body. The highest point of the rear end of the self-control rod is higher than the highest point of the pressure sensor on the front side.

[0013] Preferably, the inner side wall of the protective cover is provided with a row of accommodation grooves at equal intervals, a row of connecting frames is arranged between the two protective covers, the left and right ends of the connecting frame are inserted into the corresponding accommodation grooves, and the maximum distance between the inner side walls of the two protective covers is less than the length of the connecting frame.

[0014] Preferably, the left and right ends of the connecting frame are internally penetrated by a self-pull rod, one end of the self-pull rod is fixedly connected with the interior of the protective cover, the other end of the self-pull rod penetrates the interior of the gas storage bag and is connected with the extrusion plate, the extrusion plate and the gas storage bag are installed in the groove formed in the interior of the connecting frame, the upper and lower sides of the interior of the connecting frame are internally slotted and embeddedly installed with an arc-shaped anti-falling control air bag, the inner sides of the upper and lower sides of the outer end of the gas storage bag are internally connected with the interior of the anti-falling control air bag through connecting pipes, and the connecting pipes penetrate the interior of the connecting frame.

[0015] Another technical scheme provided by the application is to provide a protection system of an industrial gateway for data acquisition and transmission based on the Internet of Things, which comprises a monitoring module, a signal transmission module, a central processing module and an alarm module installed in the gateway body.

[0016] Compared with the prior art, the industrial gateway based on the Internet of Things and the protection system thereof have the beneficial effects that the industrial gateway has dustproof and moistureproof protection performance, and the industrial gateway can well perform data acquisition and transmission work, and the specific contents are as follows:

[0017] By using the two protective covers in the shape of "L" in the planar section and cooperating with the sealing gasket, the outer sides of the plurality of communication interfaces can be sealed and covered, so that when the industrial gateway is not used, the dust and moisture in the outside can be prevented from entering the communication interfaces, thereby facilitating the protection of the metal parts in the communication interfaces, avoiding affecting the use of the communication interfaces, and making the industrial gateway have dustproof and moistureproof protection performance, and facilitating the industrial gateway to well perform data acquisition and transmission work.

[0018] Further, when the gateway body is installed and used through the mounting frame, the self-control rod can be automatically pushed, so that the self-control rod drives the transmission gear and the vertical rod to rotate through the rack body, thereby making the self-pushing plate automatically push the two lower connecting pieces to move outward, and then automatically driving the two protective covers to move outward and open, which is convenient to operate and does not need manual operation of the staff or additional use of a power source.

[0019] In the later period, the mutual adsorption of the two adsorption blocks made of magnet block materials with different magnetic poles can improve the stability of the contact between the two protective covers.

[0020] The pressure received can be monitored in real time through the pressure sensor in the monitoring module, when the screw in the mounting frame is loose, at this time, the self-control rod will be away from the pressure sensor, so that the monitored pressure becomes smaller, and then an alarm is sent through the alarm, so that the protection system can monitor and protect the mounting structure, thereby ensuring the safety of the industrial gateway in use, and avoiding damage to the industrial gateway.

[0021] The two protective covers move outward, driving the self-pulling rod and the extrusion plate to move outward, thereby extruding the storage gas bag with the extrusion plate, so that the gas in the storage gas bag enters the anti-withdrawal control gas bag, and through the cooperation of multiple anti-withdrawal control gas bags, the upper and lower sides of the connection end of the wire harness inserted into the communication interface can be extruded and fixed, thereby further improving the stability of the wire harness inserted into the communication interface, and avoiding the wire harness from being loosened and falling off due to accidental pulling;

[0022] At the same time, through the setting of the anti-withdrawal control gas bag, the front side of the communication interface can be further covered and sealed, and the dust and moisture from the outside can be further prevented from entering the communication interface in which the wire harness is inserted.
