[0008] Preferably, the automatic control component includes a vertical rod installed in a groove opened inside the bottom surface of the gateway body, the upper outer key of the vertical rod is connected to a transmission gear, and two groups 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 groups of lower connecting pieces move toward each other synchronously through the self-push plate.

[0009] Preferably, the front end of the "L"-shaped self-control rod is slidably inserted into the 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, the outer side of the rack body is meshed with a transmission gear, and 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] Compared with the prior art, the beneficial effects of the present invention are as follows: the industrial gateway for data collection and transmission based on the Internet of Things and its protection system enable the industrial gateway to have dust and moisture-proof protection performance, which facilitates the industrial gateway to perform data collection and transmission work well. The specific contents are as follows: Through the use of two protective covers in an "L" shape in top view and sealing gaskets, the outer sides of multiple communication interfaces can be sealed and covered, so that when the industrial gateway is not in use, dust and moisture from the outside can be prevented from entering the communication interface, and then the metal parts in the communication interface can be protected to avoid affecting the use of the communication interface, so that the industrial gateway has dust and moisture protection performance, which is convenient for the industrial gateway to perform data collection and transmission work well; Furthermore, when the gateway body is installed and used through the mounting frame, it will automatically push the self-control rod, so that the self-control rod drives the transmission gear and the vertical rod to rotate through the rack body, thereby causing the self-pushing plate to automatically push the two lower connecting parts to move outward, and then automatically drive the two protective covers to move outward and open, which is convenient to operate, does not require manual operation by the staff, and does not require the use of an additional power source; Later, the stability of the contact between the two protective covers can be improved by the mutual adsorption of two adsorption blocks made of magnet blocks with opposite magnetic poles.

[0014] The pressure sensor in the monitoring module can be used to monitor the pressure in real time. When the screws in the mounting bracket become loose, the automatic control rod will move away from the pressure sensor, causing the monitored pressure to decrease, and then an alarm will be sounded through the alarm. This allows the protection system to monitor and protect the installation structure, thereby ensuring the safety of the industrial gateway during use and preventing damage to the industrial gateway.

[0015] When the two protective covers move outward, the self-pull rod and the extrusion plate will move outward together, and then the extrusion plate will squeeze the air storage bag, so that the gas in the air storage bag enters the anti-detachment control bag, thereby the upper and lower sides of the connection end of the wire harness inserted in the communication interface can be squeezed and fixed through the cooperation of multiple sets of anti-detachment control bags, so as to further improve the stability of the wire harness inserted in the communication interface and prevent the wire harness from being loosened and falling off due to accidental pulling; At the same time, through the setting of the anti-detachment control airbag, the front part of the communication interface can be further covered and sealed, which can further prevent external dust and moisture from entering the communication interface with the wiring harness inserted inside.

For the specific structure, refer to the attached Figure 1-Figure 7 And attached Fig.15 As shown, it includes a gateway body 1, and an antenna connector 2 and an alarm 3 installed on the upper surface of the gateway body 1. A row of communication interfaces 12 are installed on the front side of the gateway body 1. A protective cover 4 for shielding and protecting the communication interface 12 is connected to the front side of the gateway body 1. An automatic control component for automatically controlling the sliding opening of the protective cover 4 is installed in a groove inside the bottom surface of the gateway body 1. A pressure sensor 9, a manual telescopic rod 10 and a connecting spring 11 are installed in sequence from top to bottom in the groove opened on the rear side of the gateway body 1. The rear ends of the manual telescopic rod 10 and the connecting spring 11 are connected to the inner side wall of the rear end of the automatic control rod 6. A mounting frame 5 is installed on both the left and right sides of the rear of the gateway body 1.

[0020] The upper and lower sides of the gateway body 1 are grooved to install the limit control mechanism 7, which includes a limit slide bar 72 in a "T" shape, one end of which is connected to the gateway body 1, and a reset spring 71 is nested and connected to the outer side of the limit slide bar 72. The upper and lower sides of the protective cover 4 are respectively installed with an upper connecting piece 41 and a lower connecting piece 42 in a "7" shaped structure. The upper connecting piece 41 and the lower connecting piece 42 are both penetrated and slidably connected to the limit slide bar 72. The inner side wall of the protective cover 4 is installed with a rubber sealing gasket 43, and the inner side wall of the lower connecting piece 42 is installed with an adsorption block 44 made of a magnet block. The automatic control component It includes a vertical rod 8 installed in a groove opened inside the bottom surface of the gateway body 1, the upper outer side of the vertical rod 8 is keyed to a transmission gear 81, and two groups of self-push plates 82 are symmetrically installed on the lower outer side of the vertical rod 8. The outer side of the self-push plate 82 is provided with a lower connecting piece 42, and the two groups of lower connecting pieces 42 move toward each other synchronously through the self-push plate 82. The front end of the "L"-shaped self-control rod 6 is slidably inserted into the groove in the bottom surface of the gateway body 1, and a rack body 61 is fixed to one side of the front end of the self-control rod 6. The outer side of the rack body 61 is meshed with the transmission gear 81, and the highest point of the rear end of the self-control rod 6 is higher than the highest point of the pressure sensor 9 on the front side.

[0021] In order to better demonstrate the protection system of the industrial gateway for data acquisition and transmission based on the Internet of Things, the protection system of the industrial gateway for data acquisition and transmission based on the Internet of Things disclosed in this embodiment includes a monitoring module, a signal transmission module, a central processing module and an alarm module installed in the gateway body 1; the monitoring module can monitor the pressure through the pressure sensor 9, the signal transmission module is used to transmit the signal monitored by the monitoring module, the central processing module is used to analyze and compare the signal, and the alarm module is used to control the alarm 3 to sound an alarm.

[0022] First, when the entire industrial gateway is not installed and used, the sealing gaskets 43 on the inner walls of the two protective covers 4 are tightly fitted, so that the two protective covers 4 are used together to seal and cover the multiple communication interfaces 12 installed on the front side of the gateway body 1, thereby preventing external dust and moisture from entering the communication interface 12. At this time, the adsorption blocks 44 made of magnet blocks with opposite magnetic poles on the inner sides of the two lower connecting parts 42 generate mutual adsorption force, so that the sealing gaskets 43 on the inner sides of the two protective covers 4 can be tightly fitted and contacted. When the entire industrial gateway needs to be installed and used, the rear sides of the gateway body 1 and the mounting frame 5 are fitted and contacted with the installation area, and then the mounting frame 5 is fixedly installed on the installation with screws. In the installation area, at the same time, when the rear side of the gateway body 1 is in contact with the installation area, the installation area will automatically apply a thrust to the rear end of the self-control rod 6, so that the rear end of the self-control rod 6 automatically moves forward and enters the groove opened in the rear side of the gateway body 1. At this time, the rear end of the self-control rod 6 will be in close contact with the pressure sensor 9, so that the rear end of the self-control rod 6 applies a pressure to the pressure sensor 9. At this time, the manual telescopic rod 10 contracts, and the connecting spring 11 is squeezed to store force. At the same time, the front end of the self-control rod 6 drives the rack body 61 to move, so that the rack body 61 drives the transmission gear 81 engaged on the outside to rotate, and the transmission gear 81 drives the vertical rod 8 and the self-push plate 82 to rotate.

[0023] When the self-pushing plate 82 rotates 90°, the two groups of self-pushing plates 82 push the two groups of lower connecting pieces 42 outward at the same time. At this time, the lower connecting piece 42 slides on the outside of the limit slide bar 72 under the gateway body 1. At this time, the reset spring 71 is squeezed and stored, and the lower connecting piece 42 drives the protective cover 4 and the upper connecting piece 41 to move outward, so that the two protective covers 4 are automatically opened well, so that the communication interface 12 is exposed, and no manual operation is required by the staff. The structure is simple, and then multiple communication interfaces 12 are connected with external industrial equipment harnesses, network harnesses, etc. in turn, so that data can be collected and stored, and then the collected data is processed by the processor module in the gateway body 1, and then the processed data is transmitted to the cloud service Device or other data processing center. Since this part is existing technology, it will not be introduced in detail here. During the use of the industrial gateway, the pressure sensor 9 in the monitoring module detects the pressure in real time. When the pressure sensor 9 detects that the pressure becomes smaller, it means that the automatic control rod 6 moves backward and separates from the pressure sensor 9. At this time, it means that the screws in the mounting frame 5 are loose. At this time, the pressure sensor 9 transmits this signal to the central processing module through the signal transmission module. Then the central processing module controls the alarm 3 to sound an alarm through the alarm module after analysis and comparison, so as to remind the staff to carry out maintenance in time, so that the protection system can monitor and protect the stability of the installation structure well to avoid damage to the industrial gateway.

[0024] Embodiment 2: The industrial gateway for data collection and transmission based on the Internet of Things and its protection system in this embodiment can not only further prevent external dust and moisture from entering the communication interface 12 with the wire harness inserted inside, but also prevent the wire harness from accidentally falling off. For the specific structure, refer to the attached Figure 8-Figure 14 As shown, the inner wall of the protective cover 4 is provided with a row of accommodating grooves at equal intervals, a row of connecting frames 13 is provided between the two protective covers 4, the left and right ends of the connecting frame 13 are inserted into the corresponding accommodating grooves, the maximum distance between the inner walls of the two protective covers 4 is less than the length of the connecting frame 13, the left and right ends of the connecting frame 13 are penetrated and slidably connected with self-tensioning rods 15, one end of the self-tensioning rod 15 is fixedly connected to the inside of the protective cover 4, and the other end of the self-tensioning rod 15 penetrates the inside of the air storage bag 16 and is connected to the extrusion plate 151, and the extrusion plate 151 and the storage bag are connected. The airbags 16 are installed in the grooves opened inside the connection frame 13. The upper and lower sides of the connection frame 13 are grooved and embedded with arc-shaped anti-detachment control airbags 14. The upper and lower sides of the outer ends of the air storage airbags 16 are connected to the interior of the anti-detachment control airbags 14 through connecting pipes 141. The connecting pipes 141 penetrate the interior of the connection frame 13. On the basis of the first embodiment, when the two protective covers 4 move outward, they will drive the self-tensioning rod 15 and the extrusion plate 151 to move outward together. At this time, the extrusion plate 151 will press the inner part of the connection frame 13. The air storage bag 16 is squeezed, and the interior of the air storage bag 16 is hollow, so that the self-pull rod 15 can pass through the air storage bag 16. The outside of the air storage bag 16 is rectangular. At this time, the gas in the air storage bag 16 enters the anti-detachment control air bag 14 through the connecting pipe 141, and the volume of the anti-detachment control air bag 14 expands outward. Then, the anti-detachment control air bag 14 at the corresponding position is manually pressed slightly, and the external wiring harness is inserted into the corresponding communication interface 12. Then, the pressure on the anti-detachment control air bag 14 is released. At this time, due to the anti-detachment The volume of the control airbag 14 expands outward, so that the cooperation of multiple groups of anti-detachment control airbags 14 can squeeze and fix the upper and lower sides of the connecting end of the wiring harness inserted into the communication interface 12, to prevent the wiring harness from being accidentally pulled loose and falling off. At the same time, the expanded anti-detachment control airbag 14 can further cover and seal the front part of the communication interface 12, which can further prevent external dust and moisture from entering the communication interface 12 with the wiring harness inserted inside, so that the entire industrial gateway can perform data collection and transmission operations well.
