Technical Field

[0001] The present invention specifically relates to an underground large-scale terminal access edge gateway device based on power line carrier communication. Background Art

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The edge gateway of the present invention is suitable for underground civil air defense projects, underground pipe galleries, underground power distribution systems, underground mines, etc. It uses a multi-PLC module automatic frequency allocation algorithm to solve the interference problem, and realizes access to massive terminals through power carriers. At the same time, it ensures the stability of access through balanced load diversion, and adopts Beidou, 4G, NB, and emergency shortwave communication matrix analysis to ensure communication in emergency and wartime states.

[0031] The interface 6 is arranged on the front side of the gateway box 1, and a conductive sheet is arranged in the interface 6, and the interface 6 is electrically connected to the CPU in the gateway box 1;

[0032] The CPU in the gateway box 1 is also connected to a storage module, a cache module, a computing power module, a PLC communication module, a terminal information acquisition module, a terminal control module, a display management module and multiple PLC terminal access modules, and is also connected to a communication adaptive algorithm analysis module, a PLC topology adaptive algorithm module, a PLC topology adaptive algorithm analysis module, and a PLC frequency dynamic allocation algorithm module. The edge gateway formed is suitable for underground civil air defense projects, underground pipe galleries, underground power distribution systems, underground mines, etc. The multi-PLC module automatic frequency allocation algorithm is used to solve the interference problem, and access to massive terminals through power carriers is achieved. The communication matrix analysis of Beidou, 4G, NB, and emergency shortwave is adopted to ensure communication in emergency and wartime states, and the Bluetooth module is used to supplement the collection of on-site manual inspection data that cannot be achieved by automatic collection to ensure the security of information (the on-site manual inspection data is uploaded to the edge gateway device through the Bluetooth module, and then uploaded to the background management system by the gateway device). At the same time, the edge gateway can collect voltage and current from the PLC, and output the topology map of the system through the PLC topology adaptive algorithm;

[0033] The slide groove 7 is vertically arranged on the gateway box 1, and the baffle plate 9 is installed on the top of the slide rod 8, and the baffle plate 9 adopts an arc plate;

[0034] The baffle 9 is installed through the slide groove 7, and the baffle 9 is used to form a protective component on the gateway box 1, which can reduce the damage caused by falling rocks to the gateway box 1. In addition, the Beidou antenna 2, the 4G communication antenna 3, the NB communication antenna 4, and the Bluetooth antenna 5 also adopt a rotating installation structure, which has a passive avoidance ability. When encountering a certain impact, it can reduce the direct collision force and reduce the damage to the antenna;

[0035] The blowing structure includes a first cavity 10, a second cavity 11, a first airbag 12, a second airbag 13, an air blowing pipe 14, an air inlet pipe 15, a one-way valve 16, a pressure plate 17 and a spring 18, and the first cavity 10 and the second cavity 11 are respectively arranged on both sides of the gateway box 1;

[0036] The air blowing structure is connected to the slide bar 8 at the bottom of the baffle 9. When the baffle 9 is hit, an outward airflow can be generated inside the interface 6 through the air blowing structure to prevent the dust from falling with the falling rocks from entering the interface 6.

[0037] The first airbag 12 and the second airbag 13 are respectively installed in the first cavity 10 and the second cavity 11 through a retaining frame, two air blowing pipes 14 are installed, and the air blowing pipes 14 are composed of a main pipe and a branch pipe, and the main pipe is respectively connected to the bottom of the first airbag 12 and the second airbag 13, and the branch pipe is connected at the interface 6, and two groups of air inlet pipes 15 and one-way valves 16 are provided, which are respectively connected to the sides of the first airbag 12 and the second airbag 13, and two groups of pressure plates 17 and springs 18 are provided, and the pressure plates 17 are located at the tops of the first airbag 12 and the second airbag 13;

[0038] Specifically, when the baffle 9 is impacted downward, the pressure plate 17 is squeezed, so that the first airbag 12 and the second airbag 13 are deformed and compressed through the pressure plate 17, and the gas in the first airbag 12 and the second airbag 13 is squeezed out and sent to the interface 6 through the blowing pipe 14, so that the dust is blocked and blown out. Then, under the elastic force of the spring 18, the pressure plate 17 drives the first airbag 12 and the second airbag 13 to reset, and the air is pumped out, waiting for the next blowing. Since the air inlet pipe 15 is closer, the air is pumped out through the air inlet pipe 15 first to avoid sucking the dust back into the inlet 6. At the same time, the one-way valve 16 is used to prevent the air inlet pipe 15 from leaking.

[0039] The compression structure includes a ring sleeve 19, a pull rope 20 and a guide sleeve 21, wherein the ring sleeve 19 is located in the second cavity 11, and the ring sleeve 19 is sleeved on the second airbag 13, the pull rope 20 is connected between the ring sleeve 19 and the installation shaft of the antenna, and the pull rope 20 runs through the guide sleeve 21 for steering;

[0040] The second airbag 13 is also connected to the four antennas through a compression structure. When the antenna is hit, it rotates and can drive the pull rope 20 to move. The pull rope 20 is guided by the guide sleeve 21 and pulls the ring sleeve 19. The ring sleeve 19 compresses the second airbag 13 and can also perform blowing. When the antenna is hit by falling rocks, dust is also prevented from entering the interface 6.

[0041] Working principle: First, four antennas, namely Beidou antenna 2, 4G communication antenna 3, NB communication antenna 4 and Bluetooth antenna 5, are installed on the gateway box 1 to achieve safe and comprehensive communication. The interface on the gateway box 1 serves as a terminal access point. When the gateway box 1 is used underground, a baffle 9 is installed through a slide groove 7. The baffle 9 is used to form a protective component on the gateway box 1 to reduce the damage caused by falling rocks to the gateway box 1. The Beidou antenna 2, 4G communication antenna 3, NB communication antenna 4 and Bluetooth antenna 5 also adopt a rotating installation structure with passive avoidance capability. When encountering a certain impact, the direct collision force can be reduced to reduce the damage to the antenna. The blowing structure is connected to the sliding rod 8 at the bottom of the baffle 9. When the baffle 9 is impacted, an outward airflow can be generated inside the interface 6 through the blowing structure to prevent dust from falling with the falling rocks from entering the interface 6. Specifically, when the baffle 9 is impacted downward, the pressure plate 17 The first and second air bags 12 and 13 are squeezed and compressed by the pressure plate 17, and the gas in the first and second air bags 12 and 13 is squeezed out and sent to the interface 6 through the blowing pipe 14 to block and blow out the dust. Then, under the elastic force of the spring 18, the pressure plate 17 drives the first and second air bags 12 and 13 to reset, and the air is pumped out, waiting for the next blowing. Since the air inlet pipe 15 is closer, the air is pumped out through the air inlet pipe 15 first to avoid sucking the dust back into the inlet 6. At the same time, the one-way valve 16 is used to avoid the air inlet pipe 15 from escaping. The second air bag 13 is also connected to the four antennas through the compression structure. When the antenna is hit, it rotates and can drive the pull rope 20 to move. The pull rope 20 is guided by the guide sleeve 21 and the ring sleeve 19 is pulled. The ring sleeve 19 compresses the second air bag 13 and can also perform blowing. When the antenna is hit by falling rocks, dust is also prevented from entering the interface 6.
