A coal blockage identification system based on AI

Abstract

The present invention discloses a coal blocking identification system based on AI, which specifically relates to the field of coal transportation technology in power plants, including a coal chute and a camera, wherein a warning circle is fixedly connected to the position near the top of the coal chute. The present invention is provided with an audible and visual alarm, an LED lamp, a control button and an alarm indicator. When in use, the camera will monitor the coal falling condition inside the coal chute in real time. If the coal inside the coal chute does not pass the warning circle, it indicates that coal blocking will occur. At this time, the control center will process the signal and then feed it back to the audible and visual alarm. The alarm indicator on the audible and visual alarm flashes and lights up, and the staff is prompted by the alarm sound. At this time, the LED lamp is turned off. When there is no coal blocking, the LED lamp acts as an indicator light running in a normal state and can play a role of lighting, and the auxiliary camera monitors the coal falling condition inside the coal chute, so that the system has an alarm function and is highly practical.

[0002] In thermal power plants, coal blockage during coal transportation is a very common problem. Once it occurs, the entire coal transportation system will be paralyzed and it will be very difficult to repair. Now, the AI ​​system can be combined with the coal blockage identification system to form an AI-based coal blockage identification system. This system can effectively solve the problem of inaccurate coal blockage identification, but the system still has some problems and defects.

[0018] (3) By setting up an audible and visual alarm, an LED light tube, a control button and an alarm indicator light, when in use, the camera will monitor the coal falling condition inside the coal chute in real time. If the coal inside the coal chute does not pass the warning circle, it indicates that coal blockage will occur. At this time, the control center will process the signal and feed it back to the audible and visual alarm. The alarm indicator light on the audible and visual alarm will flash and light up, accompanied by an alarm sound to remind the staff. At this time, the LED light tube is turned off. When there is no coal blockage, the LED light tube acts as an indicator light operating under normal conditions and can play a role of lighting, assisting the camera to monitor the coal falling condition inside the coal chute.

[0027] The other ends of the air inlet pipes 14 are respectively connected to the interior of the dust hoods 5, and the dust hoods 5 are symmetrically distributed about the vertical center of the coal chute 1;

[0028] The blowing hood 11 and the camera 9 are in the same vertical plane, and the camera 9 and the center point of the coal chute 1 are in the same vertical plane;

[0029] The outer diameter of the clamping block 17 is smaller than the inner diameter of the clamping slot 18, and the clamping block 17 is embedded in the clamping slot 18, so that a clamping structure is formed between the clamping block 17 and the clamping slot 18;

[0030] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when in use, the coal on the conveyor belt falls into the coal chute 1 and the coal ash generated is diffused into the air at the top of the coal chute 1. At this time, the exhaust fan 15 is started, and the exhaust fan 15 draws away the air above the coal chute 1 through the dust hood 5. At this time, the filter 16 inside the dust hood 5 will filter out the coal ash in the air, thereby preventing the coal ash from diffusing into the outside air to cause environmental pollution, and the environmental protection performance is strong; the wind extracted by the exhaust fan 15 is transported through the exhaust pipe 13, and finally discharged through the blow hood 11. The wind blown by the blow hood 11 acts on the camera 9, so that the dust attached to the camera 9 can be blown away, thereby ensuring the normal operation of the camera 9, which is conducive to the normal operation of the system.

[0031] Embodiment 2: The alarm mechanism 7 is composed of a sound and light alarm 701, an LED lamp tube 702, a control button 703 and an alarm indicator light 704. The sound and light alarm 701 is fixedly connected to the front end of the vertical plate 6 near the top. The model of the sound and light alarm 701 can be TGSG-03. One side of the front end of the sound and light alarm 701 is fixedly connected with the LED lamp tube 702, the top of the sound and light alarm 701 is fixedly connected with the control button 703, and the other side of the front end of the sound and light alarm 701 is fixedly connected with the alarm indicator light 704;

[0032] The vertical plane where the front end of the sound and light alarm 701 is located is located at the rear end of the vertical plane where the camera 9 is located;

[0033] Specifically, Figure 1 and Figure 4 As shown, when in use, the camera 9 will monitor the coal falling conditions inside the coal chute 1 in real time. If the coal inside the coal chute 1 does not pass the warning circle 2, it indicates that coal blockage will occur. At this time, the control center 8 will process the signal and feed it back to the sound and light alarm 701. The alarm indicator light 704 on the sound and light alarm 701 will flash and light up, and the staff will be prompted by the alarm sound. At this time, the LED lamp tube 702 is turned off. When there is no coal blockage, the LED lamp tube 702 serves as an indicator light for the operation of the sound and light alarm 701 under normal conditions and can play a lighting role, assisting the camera 9 to monitor the coal falling conditions inside the coal chute 1. In this way, the system has an alarm function and is more practical.

[0034] Working principle: When the present invention is in use, first, the camera 9 will monitor the coal falling conditions inside the coal chute 1 in real time. If the coal inside the coal chute 1 does not pass the warning circle 2, it indicates that coal blockage will occur. At this time, the control center 8 will process the signal and feed it back to the sound and light alarm 701. The alarm indicator light 704 on the sound and light alarm 701 will flash and light up, and the staff will be prompted by the alarm sound. At this time, the LED lamp tube 702 is turned off. When there is no coal blockage, the LED lamp tube 702 serves as an indicator light for the operation of the sound and light alarm 701 under normal conditions and can play a role of lighting, assisting the camera 9 to monitor the coal falling conditions inside the coal chute 1, so that the system has an alarm function and is more practical.

[0035] Afterwards, when in use, the coal on the conveyor belt falls into the coal chute 1, and the coal ash generated inside the coal chute 1 diffuses into the air at the top of the coal chute 1. At this time, the exhaust fan 15 is started, and the exhaust fan 15 draws away the air above the coal chute 1 through the dust hood 5. At this time, the filter net 16 inside the dust hood 5 will filter out the coal ash in the air, thereby preventing the coal ash from diffusing into the outside air to cause environmental pollution, and the environmental protection performance is strong.

[0036] Finally, the air extracted by the exhaust fan 15 is transported through the exhaust pipe 13 and finally discharged through the blow hood 11. The air blown by the blow hood 11 acts on the camera 9, so that the dust attached to the camera 9 can be blown off, thereby ensuring the normal operation of the camera 9 and facilitating the normal operation of the system.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
