[0028] like Figure 1-6 As shown, an embodiment of the present invention provides a comprehensive monitoring system for a closed area of ​​a mine, including a box body 1 and a central control device. An air intake component 2 is arranged on the left side of the box body 1, a monitoring component 3 is arranged on the bottom of the box body 1, a main board 4 is fixedly connected to the top surface of the inner part of the box body 1 (this is the prior art and will not be repeated here), which can process the monitoring data, a waterproof film is arranged at the bottom of the main board 4 to protect the main board 4, a methane sensor 5, a carbon monoxide sensor 6, a carbon dioxide sensor 7, an oxygen sensor 8, a temperature and humidity sensor 9 and an air pressure sensor 10 are fixedly connected to the bottom of the main board 4, which are respectively used to monitor the methane concentration, carbon monoxide concentration, carbon dioxide concentration, oxygen concentration and temperature and humidity in the air, and the air pressure sensor 10 The sensor 10 monitors the air pressure in the enclosed area of ​​the mine in a non-working state, improves the monitoring intensity, and expands the monitoring data surface. An air pump 11 is fixedly connected to the inner bottom surface of the box body 1, and an air outlet pipe 12 is fixedly connected to the right side wall of the air pump 11. The inside of the air outlet pipe 12 is fixedly connected to a right filter 13. When the air pump 11 is started, external air can be drawn into the box body 1 from the air intake component 2 and discharged from the air outlet pipe 12. A micro motor 14 is fixedly connected to the inner bottom surface of the box body 1, and an alarm 15 and a buzzer 16 are fixedly connected to the bottom of the box body 1. When one of the monitoring data does not meet the standard, the alarm 15 and the buzzer 16 both work to issue a warning, and a connecting optical fiber 17 is fixedly connected to the right side wall of the box body 1.

[0029] The air intake assembly 2 includes an air inlet pipe 201, a snap ring 202, a left filter screen 203, an air pipe 204, a connecting pipe 205, a spray head 206, a hose 207, and a micro high-pressure air pump 208. Inside the air inlet pipe 201, there is a fixed snap ring 202. The number of snap rings 202 is set to two, and they are distributed left and right. A left filter screen 203 is clamped between the two snap rings 202. Inside the air inlet pipe 201, there is an air pipe 204 in a "field" shape. At the bottom of the air pipe 204, there is a fixed connecting pipe 205. On the air pipe 204, there are fixed spray heads 206. The number of spray heads 206 is set to multiple and they are evenly distributed on the air pipe 204. All the spray heads 206 face the left filter screen 203.

[0030] The monitoring assembly 3 includes a bottom box 301, a bottom hole 302, a main gear shaft 303, a driven gear ring 304, a cleaning rod 305, a cleaning sponge 306, an outer cover 307, and a spherical camera 308. The top of the bottom box 301 is fixedly connected to the box body 1. At the bottom of the bottom box 301, there is a bottom hole 302. Inside the bottom box 301, there is a main gear shaft 303. On the left side of the main gear shaft 303, there is a meshing driven gear ring 304. At the bottom of the driven gear ring 304, there is a fixed cleaning rod 305. On the cleaning rod 305, there is a fixed cleaning sponge 306. Both the cleaning rod 305 and the cleaning sponge 306 are arc-shaped. Inside the driven gear ring 304, there is a rotatably connected outer cover 307. The cleaning sponge 306 is closely attached to the surface of the outer cover 307. Inside the outer cover 307, there is a spherical camera 308. The bottom output end of the micro motor 14 is fixedly connected to the main gear shaft 303. The tops of both the outer cover 307 and the spherical camera 308 are fixedly connected to the box body 1. The outer cover 307 is made of transparent plastic material and is located inside the bottom hole 302. Both the main gear shaft 303 and the driven gear ring 304 are located inside the bottom box 301. When the micro motor 14 is started, the main gear shaft 303 rotates, thereby driving the driven gear ring 304 to rotate on the outer cover 307. The lower cleaning rod 305 and cleaning sponge 306 clean the surface of the outer cover 307 to remove the attached dust, ensuring clear imaging of the spherical camera 308.

[0031] The micro high-pressure air pump 208, the spherical camera 308, the vacuum pump 11, the micro motor 14, the alarm 15 and the buzzer 16 are all electrically connected to the main board 4 and to the external power supply system. The main board 4 is connected to the central control device via the connecting optical fiber 17. The monitoring data can be transmitted to the central control device via the connecting optical fiber 17. The central control device processes the monitoring data to facilitate the operator to directly view the data and make comparisons. An installation angle code 18 is fixedly connected to the box body 1. There are multiple installation angle codes 18, which are evenly distributed on the four side walls of the box body 1. By installing the angle code 18, the box body 1 can be installed inside the mine.

[0032] Working principle: The box body 1 can be installed inside the mine by installing the angle code 18. Multiple box bodies 1 are evenly distributed in the closed area of ​​the mine. They are connected to the central control equipment by connecting optical fiber 17. When monitoring, the vacuum pump 11 is started to draw external gas from the air intake component 2 into the box body 1 and discharge it from the air outlet pipe 12. After the gas entering the box body 1 passes through the methane sensor 5, carbon monoxide sensor 6, carbon dioxide sensor 7, oxygen sensor 8 and temperature and humidity sensor 9, each sensor detects the methane concentration, carbon monoxide concentration, carbon dioxide concentration, oxygen concentration and temperature and humidity in the gas. The air pressure sensor 10 monitors the air pressure in the closed area of ​​the mine when the vacuum pump 10 is not working. The data is processed by the main board 4 and transmitted to the central control device through the connecting optical fiber 17. At the same time, when one item in the gas does not meet the standard, the alarm 15 and the buzzer 16 both work to issue a warning. After a long period of work, the micro high-pressure air pump 208 is started, and a high-pressure and high-speed airflow is delivered to the air pipe 204 through the hose 207, and sprayed from the nozzle 206 to clean the left filter 203 to ensure that the air intake of the air inlet pipe 201 is unobstructed. The micro motor 14 is started to rotate the main gear shaft 303, thereby driving the slave gear ring 304 to rotate on the outer cover 307, and the cleaning rod 305 and the cleaning sponge 306 below clean the surface of the outer cover 307 to remove the attached dust and ensure that the spherical camera 308 can take clear pictures.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
