Description

Technical Field

[0001] This invention relates to the field of intelligent alarm systems, and more particularly to an artificial intelligence alarm system based on a visual image sensor. Background Technology

[0002] Combustible gas alarms used in mines are safety devices specifically designed to monitor the concentration of combustible gases in enclosed environments such as mines and tunnels. They monitor the presence of combustible gases in the air in real time using a combustible gas monitor and issue timely alerts when combustible gas levels exceed safe limits, ensuring personnel safety. However, the ventilation systems in mines are complex and airflow is turbulent. Mine alarms cannot identify the direction and source of combustible gases, nor their flow, diffusion, or convergence. Therefore, after the alarm sounds, miners evacuating along designated escape routes cannot observe the flow, diffusion, or convergence of combustible gases. Although mines are equipped with intelligent ventilation systems, if miners move towards actual combustible gas convergence areas along the designated escape routes, they will be exposed to highly toxic environments, potentially leading to poisoning from inhaling excessive amounts of combustible gases. Summary of the Invention

[0003] To overcome the drawback that workers may accidentally enter flammable gas accumulation areas and suffer poisoning during evacuation because they cannot observe the flow, diffusion, and convergence direction of flammable gases, this invention provides an artificial intelligence alarm system based on a visual image sensor.

[0007] Furthermore, an electronic atomizer is installed at the bottom of the liquid storage tank; the outlet of the electronic atomizer is connected to a spray pipe.

[0008] Furthermore, the powder conveying mechanism includes a storage cylinder, a discharge pipe, a conveying pipe, a second rotating shaft, a second motor, a second fan, and a venting pipe; the storage cylinder is fixedly connected to the electric turntable; the color-developing phosphor is stored inside the storage cylinder; the discharge pipe is fixedly connected to the storage cylinder; the bottom of the discharge pipe has several through-channel structures connecting to the storage cylinder; the discharge pipe and the venting pipe are connected to the conveying pipe; the second rotating shaft is rotatably connected inside the discharge pipe; a second motor is installed on the discharge pipe to drive the second rotating shaft to rotate; a second fan is fixedly connected to the second rotating shaft to sequentially draw the color-developing phosphor into the conveying pipe; a venting pipe for compensating for internal air pressure is connected to the storage cylinder, and the air inlet of the venting pipe is connected to the liquid storage tank.

Furthermore, by connecting multiple audible and visual alarms into an Internet of Things (IoT) system, once any sensor detects an excessive concentration of combustible gas (such as methane), the system instantly triggers all audible and visual alarms throughout the entire mine network.

Furthermore, the color-developing fluorescent powder can mark flammable gas accumulation areas in the mine, warning evacuating workers not to accidentally enter the marked areas. Meanwhile, the spray pipe continuously sprays spray liquid into the mine to reduce the concentration of flammable gas. This invention, an artificial intelligence alarm system based on a visual image sensor, solves the technical problem that workers are prone to accidentally entering flammable gas accumulation areas and suffering poisoning during evacuation because they cannot observe the flow, diffusion, and accumulation direction of flammable gas.

Detailed Implementation

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0017] Example 1 This invention provides an artificial intelligence alarm system based on a visual image sensor, such as... Figures 1-6 As shown, the system includes a mounting frame 1, an audible and visual alarm 2, a visual image monitoring device 3, a liquid storage tank 4, an electronic atomizer 41, a spray pipe 42, an electric turntable 5, an air inlet pipe 61, a combustible gas detector 62, a gas suction machine 63, an air outlet pipe 71, a first rotating shaft 72, a first motor 73, a first fan 74, and a powder conveying mechanism. The audible and visual alarm 2 and the visual image monitoring device 3 are sequentially mounted on the mounting frame 1. The visual image monitoring device 3 contains a visual image sensor. The liquid storage tank 4 is fixedly connected to the mounting frame 1 and is filled with spray liquid. The installation height of the liquid storage tank 4 is lower than the installation height of the visual image monitoring device 3. The electronic atomizer 41 is installed at the bottom of the liquid storage tank 4. The outlet of the electronic atomizer 41 is connected to the spray pipe 42. The electric turntable 5 is mounted on the liquid storage tank 4. An air inlet pipe 61 is fixedly connected to the turntable component of the rotating disk 5; the air outlet port at the lower part of the air inlet pipe 61 is immersed below the liquid surface of the spray liquid in the storage tank 4; a combustible gas detector 62 is installed at the air inlet port at the upper part of the air inlet pipe 61; a gas suction machine 63 is installed at the air inlet port at the upper part of the air inlet pipe 61; an air outlet pipe 71 is fixedly connected to the rotating component of the electric turntable 5; the air inlet port at the lower part of the air outlet pipe 71 is above the liquid surface of the spray liquid in the storage tank 4; a first rotating shaft 72 is rotatably connected inside the air outlet pipe 71; a first motor 73 is installed on the rotating component of the electric turntable 5; the output shaft of the first motor 73 is fixedly connected to the first rotating shaft 72; two first fans 74 are fixedly connected to the first rotating shaft 72; a powder conveying mechanism is fixedly connected to the electric turntable 5; the powder conveying mechanism is filled with color developing fluorescent powder 8; the powder conveying mechanism is connected to the air outlet pipe 71.

[0018] like Figure 3 and Figure 4 As shown, the inlet pipe 61 is equipped with a detachable and replaceable combustible gas adsorption column 65; the gas suction machine 63 is equipped with a directional suction hood 64, and the suction port of the directional suction hood 64 faces away from the outlet pipe 71; the outlet port of the outlet pipe 71 is fixedly connected to a directional air outlet hood 75 that guides the airflow to blow away from the inlet pipe 61; the directional air outlet hood 75 is equipped with an illumination lamp 76 for irradiating the blown-out color-developing phosphor 8.

[0019] The working steps of an artificial intelligence alarm system based on a visual image sensor according to the present invention are as follows.

[0020] A gas extraction machine 63 continuously draws outside air into the intake pipe 61 through a directional suction hood 64. A combustible gas detector 62 monitors the concentration of combustible gas in the air flowing through the intake pipe 61. When the combustible gas detector 62 detects that the concentration of combustible gas in the air exceeds the standard, an audible and visual alarm 2 quickly sounds an alarm to notify the staff to evacuate. By connecting multiple audible and visual alarms into an Internet of Things (IoT) system, once any sensor detects that the concentration of combustible gas (such as methane) exceeds the standard, the system will instantly trigger all audible and visual alarms throughout the entire mine network. Whether in the main roadway or in the most remote work area, all personnel can receive the alarm simultaneously, buying the most valuable time for evacuation and emergency response. The system also sends a signal to the back-end control center, allowing supervisors to accurately locate which sensor triggered the alarm at which location. Rescue and disposal teams can directly approach the leak point with extremely high efficiency, avoiding blind searches in hazardous environments. Simultaneously, the powder conveying mechanism delivers powdered color-developing phosphor 8 into the air outlet pipe 71. At the same time, the first motor 73 drives the first rotating shaft 72 and the first fan 74 to rotate rapidly. The first fan 74 continuously generates airflow inside the air outlet pipe 71, blowing towards the directional air outlet hood 75. After the color-developing phosphor 8 is blown outward from the air outlet pipe 71 and the directional air outlet hood 75 with the airflow, due to the presence of environmental airflow flowing in a certain direction in the mine, the blown-out color-developing phosphor 8 is affected by the external environmental airflow and diffuses in the direction of the environmental airflow. At this time, the visual image monitoring device 3 can intelligently identify the direction of diffusion of the color-developing phosphor 8 with the environmental airflow through the provided visual image sensor. The direction of the environmental airflow is the downwind direction, and the opposite direction of the environmental airflow is the upwind direction. This allows for the separate deduction of the upwind direction of the source of the combustible gas and the downwind direction of the flow and diffusion of the combustible gas.

[0021] Next, the electric turntable 5 drives the intake pipe 61 and the outlet pipe 71 to rotate, so that the directional suction hood 64 of the intake pipe 61 faces the upwind direction of the source of the combustible gas, and the directional exhaust hood 75 of the outlet pipe 71 faces the downwind direction of the flow and diffusion of the combustible gas. The gas suction machine 63 continuously draws outside air carrying combustible gas into the intake pipe 61 through the directional suction hood 64 towards the upwind direction. As the outside air carrying combustible gas passes through the combustible gas adsorption column 65, the combustible gas adsorption column 65 can adsorb most of the combustible gas carried in the air to complete the first purification treatment. The purified air enters the spray liquid in the storage tank 4 along the intake pipe 61. The spray liquid dissolves the remaining combustible gas in the purified air to complete the second purification treatment. After the two purification treatments, the air rises away from the spray liquid and gathers in the storage tank. Above the liquid tank 4, a rapidly rotating first fan 74 continuously blows the purified air gathered above the liquid tank 4 toward the directional exhaust hood 75, allowing the purified air to be blown out of the directional exhaust hood 75 toward the downwind direction. This purifies some of the air in the mine that carries flammable gases. At the same time, the powder conveying mechanism continuously delivers powdered fluorescent powder 8 into the exhaust pipe 71. The fluorescent powder 8 is blown out toward the downwind direction along with the purified air. Simultaneously, the lighting lamp 76 illuminates the fluorescent powder 8, generating a large amount of fluorescent reflection. This allows evacuating personnel to clearly observe the fluorescent reflection from the fluorescent powder 8 and identify the downwind direction of the flammable gas flow by judging the blowing direction of the fluorescent powder 8. This prevents evacuating personnel from accidentally entering the flammable gas flow, diffusion, and accumulation area.

[0022] During the process of the gas suction machine 63 continuously pumping air carrying flammable gases from the mine shaft to the flammable gas adsorption column 65 for purification, the electronic atomizer 41 continuously delivers the spray liquid in the storage tank 4 to the spray pipe 42 in an atomized state. The atomized spray liquid is sprayed into the mine shaft through the spray pipe 42. In this embodiment, the spray pipe 42 is designed with a ring structure, which can increase the spray area of ​​the spray liquid. The sprayed atomized spray liquid reduces and dilutes the remaining flammable gases flowing through this area of ​​the mine shaft, effectively reducing the concentration of flammable gases in the mine shaft. At the same time, the mine shaft is equipped with an intelligent ventilation system that continuously removes flammable gases from the mine shaft, further reducing the concentration of flammable gases in the mine shaft and greatly improving the success rate of workers safely evacuating from the flammable gas diffusion area.

[0023] The powder conveying mechanism includes a storage cylinder 81, a discharge pipe 82, a conveying pipe 83, a second rotating shaft 84, a second motor 85, a second fan 86, a splined shaft 87, a compression spring 88, a scraper 89, and a vent pipe 91; the storage cylinder 81 is fixedly connected to the electric turntable 5; the color-developing fluorescent powder 8 is stored in the storage cylinder 81; the discharge pipe 82 is fixedly connected to the storage cylinder 81; the bottom of the discharge pipe 82 has several through-channel structures 8201 that connect to the storage cylinder 81; the discharge pipe 82 and the vent pipe 71 are connected to the conveying pipe 83; the second rotating shaft 84 is rotatably connected inside the discharge pipe 82; the second motor 85 is installed on the discharge pipe 82; the output shaft of the second motor 85 is fixedly connected to the second rotating shaft 84; the second rotating shaft 84 is fixedly connected to the second rotating shaft 84. A second fan 86 is connected; the lower end of the second rotating shaft 84 passes through the discharge pipe 82, and a spline shaft 87 is slidably connected inside the second rotating shaft 84; a compression spring 88 is fixedly connected between the spline shaft 87 and the second rotating shaft 84, and the compression spring 88 is sleeved on the outer surface of the spline shaft 87; two scraper blades 89 are fixedly connected to the lower end of the spline shaft 87; both scraper blades 89 are in close contact with the upper surface of the color developing phosphor powder 8, and the compression spring 88 is initially in a compressed state; the bottom of both scraper blades 89 is provided with several scraping tooth structures to scrape and separate the clumps of color developing phosphor powder 8; a vent pipe 91 for compensating for internal air pressure is connected to the storage cylinder 81, and the air inlet of the vent pipe 91 is connected to the liquid storage tank 4; the specific working steps of the powder conveying mechanism are as follows.

[0024] The specific steps of the powder conveying mechanism continuously conveying powdered colorimetric phosphor 8 into the air outlet pipe 71 are as follows: the second motor 85 drives the second rotating shaft 84 and the second fan 86 to rotate rapidly. The second fan 86 generates an upward suction force in the discharge pipe 82. At the same time, the second rotating shaft 84 drives the spline shaft 87 and the two scrapers 89 to rotate rapidly. Simultaneously, the compression spring 88, which is initially in a compressed state, pushes the spline shaft 87 to drive the rotating scrapers 89 to continuously scrape the upper surface of the colorimetric phosphor 8 in the storage cylinder 81, so that the colorimetric phosphor 8 in the storage cylinder 81 is successively scraped loose into an upward-scattering powder. At the same time, the suction force in the discharge pipe 82 sequentially draws in the upward-scattering powdery colorimetric phosphor 8, and the second fan 86 continuously blows the drawn colorimetric phosphor 8 into the air outlet pipe 71 through the conveying pipe 83, so that the colorimetric phosphor 8 in the storage cylinder 81 is continuously conveyed towards the air outlet pipe 71 in a scattered powdery form.

[0025] Example 2, as Figures 1-6As shown, based on the above embodiment 1, an electric push rod 92 is installed on the fixed outer shell of the electric turntable 5 in this embodiment; a sealing plug 93 is fixedly connected to the telescopic end of the electric push rod 92; the sealing plug 93 is inserted into the air inlet port of the vent pipe 91 to prevent a large amount of humid gas from the liquid storage tank 4 from entering the inside of the storage cylinder 81 through the vent pipe 91, thereby preventing the color developing phosphor 8 in the storage cylinder 81 from becoming damp and clumping. When it is necessary to transport the color developing phosphor 8 to the conveying pipe 83, the electric push rod 92 pushes the sealing plug 93 downward away from the vent pipe 91, so that the vent pipe 91 can connect to the air that has been filtered inside the liquid storage tank 4. Although this part of the air is in a humid state, after this part of the humid air enters the storage cylinder 81, it will quickly flow to the air outlet pipe 71 through the discharge pipe 82. Therefore, the air continuously transported during this period will not cause the color developing phosphor 8 in the storage cylinder 81 to become damp and clumping.

[0026] Example 3, as Figures 1-6 As shown, based on the above embodiment 1, the storage cylinder 81 in this embodiment is equipped with a heater 10. If the mine is in a humid environment, some humid gas will enter the storage cylinder 81 along the gas outlet pipe 71, the material conveying pipe 83, and the material discharge pipe 82, causing the color developing phosphor powder 8 to become damp and clump together. When it is necessary to transport the color developing phosphor powder 8 to the material conveying pipe 83, the heater 10 will heat the color developing phosphor powder 8 in time to quickly evaporate the moisture adsorbed in the color developing phosphor powder 8, so that the color developing phosphor powder 8 can be restored to a dry state as soon as possible.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
