Description

Technical Field

[0001] This utility model relates to the field of mine production safety technology, and in particular to a coal mine pedestrian and vehicle-stopping alarm and interlocking system. Background Technology

[0002] In the field of coal mine safety production, ensuring personnel safety is always the top priority. Although the current electronic fence system in coal mines plays a certain role in safety protection, its technical shortcomings are becoming increasingly apparent as the requirements for safety production continue to rise.

[0003] Most existing electronic fence systems in coal mines are built upon traditional security technologies. For example, some use infrared sensing technology, which works by using the human body to block infrared light and trigger an alarm. However, this technology has significant drawbacks in the complex environment of coal mine tunnels. Infrared light is easily interfered with by dust, moisture, and other pollutants, resulting in a high false alarm rate. Furthermore, it cannot accurately locate personnel. Once an alarm is triggered, staff cannot quickly determine the location of the intruder, delaying rescue and response efforts.

[0004] As coal mining depth and breadth expand, the tunnel network becomes increasingly complex, making the need for precise personnel positioning ever more urgent. Traditional human body positioning methods are limited and cannot accurately detect personnel, resulting in low accuracy of safety alarms. This has become a key bottleneck restricting coal mine safety production from reaching a higher level. Utility Model Content

[0005] Therefore, it is necessary to provide a coal mine pedestrian and vehicle inactivity alarm and interlocking system to address the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model provides a mine pedestrian and vehicle inactivity alarm interlocking system, comprising: a mine-use explosion-proof and intrinsically safe computer, a mine-use intrinsically safe wireless communication alarm infrared camera, a mine-use explosion-proof and intrinsically safe voice alarm, a mine-use intrinsically safe infrared microwave motion detector, a mine-use intrinsically safe wireless dual-mode base station, and a UWB positioning card. The mine-use intrinsically safe wireless dual-mode base station consists of a switch, a UWB base station, and a WIFI base station. The UWB base station and the WIFI base station are connected to the mobile communication network through the switch. The switch is communicatively connected to the mine-use explosion-proof and intrinsically safe computer and the mine-use intrinsically safe wireless communication alarm infrared camera. The mine-use explosion-proof and intrinsically safe voice alarm is wirelessly connected to the WIFI base station via WIFI. The mine-use intrinsically safe infrared microwave motion detector is wirelessly connected to the mine-use explosion-proof and intrinsically safe voice alarm. The UWB base station is wirelessly connected to the UWB positioning card worn by underground personnel via UWB. The mine-use explosion-proof and intrinsically safe computer is communicatively connected to the mining equipment.

[0007] Preferably, the mining equipment is a winch, transfer machine, tunneling machine, or crusher, and the mining explosion-proof and intrinsically safe computer is communicatively connected to at least one of the winch, transfer machine, tunneling machine, and crusher.

[0008] Preferably, it also includes a mine-use explosion-proof and intrinsically safe power supply and a mine-use explosion-proof and intrinsically safe DC regulated power supply. The mine-use explosion-proof and intrinsically safe power supply is electrically connected to the mine-use intrinsically safe wireless communication alarm infrared camera, and the mine-use explosion-proof and intrinsically safe DC regulated power supply is electrically connected to the switch.

[0009] Preferably, it also includes a mobile terminal, which is installed on the personnel working underground and communicates with the WIFI base station via WiFi.

[0010] Preferably, the intrinsically safe wireless communication alarm infrared camera and the intrinsically safe explosion-proof voice alarm for mining are connected to a WIFI base station.

[0011] Preferably, the UWB base station, the intrinsically safe wireless communication alarm infrared camera, and the intrinsically safe explosion-proof voice alarm can all send a first alarm signal and a second alarm signal to the intrinsically safe explosion-proof computer; triggered by the first signal, the intrinsically safe explosion-proof computer controls the intrinsically safe explosion-proof voice alarm and / or the intrinsically safe wireless communication alarm infrared camera to sound an alarm; triggered by the second signal, the intrinsically safe explosion-proof computer controls the mining equipment to stop.

[0012] Compared with existing technologies, this technical solution has at least one of the following beneficial effects: it achieves multiple means of safety alarm through UWB positioning technology, infrared camera detection technology and infrared microwave detection technology, and can accurately detect personnel, thereby improving the detection accuracy and thus improving the accuracy of safety alarms and reducing safety accidents caused by human factors.

[0015] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] Please see Figure 1 This application provides a coal mine pedestrian and vehicle inactivity alarm interlocking system, including: a mine-use explosion-proof and intrinsically safe computer 1, a mine-use intrinsically safe wireless communication alarm infrared camera 2, a mine-use explosion-proof and intrinsically safe voice alarm 3, a mine-use intrinsically safe infrared microwave motion detector 4, a mine-use intrinsically safe wireless dual-mode base station 5, a UWB positioning card 6, a mine-use explosion-proof and intrinsically safe power supply 11, and a mine-use explosion-proof and intrinsically safe DC regulated power supply 12. The mine-use intrinsically safe wireless dual-mode base station 5 consists of three parts: a switch 7, a UWB base station 8, and a WIFI base station 9. The UWB base station 8 and WIFI base station 9... IFI base station 9 accesses the mobile communication network through switch 7. Switch 7 is connected to the intrinsically safe and explosion-proof computer 1 and the intrinsically safe wireless communication alarm infrared camera 2. The intrinsically safe and explosion-proof voice alarm 3 is connected to WIFI base station 9 via WIFI wireless communication. The intrinsically safe infrared microwave motion detector 4 is connected to the intrinsically safe and explosion-proof voice alarm 3 via UWB base station 8 and the UWB positioning card 6 worn by underground personnel via UWB wireless communication. The intrinsically safe and explosion-proof computer 1 is connected to mining equipment 10 via communication.

[0017] The intrinsically safe and explosion-proof mining computer, model KJD127, uses an industrial-grade reinforced motherboard, shockproof hard drive, CD burner, and industrial Ethernet port. It comes pre-installed with Windows 10 operating system software and is equipped with an FHS1.5W intrinsically safe mining wireless mouse and an FHJ1.5W intrinsically safe mining wireless keyboard. It features time retrieval, event retrieval, and printing functions; and video / audio playback, fast forward / rewind, speed adjustment, playback, storage, full playback, frame-by-frame playback, pause, and display functions, possessing the functions of a standard industrial computer. The intrinsically safe and explosion-proof mining computer 1 communicates with switch 7 via a network cable.

[0018] Switch 7 is a KJJH-12 intrinsically safe ring network switch for mining. Switch 7 provides access to the fiber optic wired LAN. UWB base station 8 and WIFI base station 9 are connected to switch 7 through RJ-45 Ethernet interfaces. CPE is connected to the 4G network, thus completing the network access function. Data from the connected UWB and WIFI devices is exchanged and connected with other devices and servers through UWB base station 8, WIFI base station 9 and optical switch.

[0019] The intrinsically safe wireless intercom alarm infrared camera for mining, model KBA12WH, uses an embedded voice communication system to achieve local area network voice communication. It features a dual-microphone design for synchronized audio and video and voice intercom, ensuring independent operation without interference. It automatically recognizes the ambient lighting conditions and switches to infrared illumination accordingly, guaranteeing smooth video in low-light environments. The camera connects to a switch (7) via fiber optic cable and can also connect to a Wi-Fi base station (9) via Wi-Fi. It features infrared illumination for clear visibility in low light, voice broadcasting and intercom functions, and is powered by two separate power supplies.

[0020] The mine explosion-proof and intrinsically safe voice alarm 3 is suitable for use in coal mines, including various entrances and loading / unloading areas in transport roadways where there is a risk of gas and coal dust explosions.

[0021] The following products are manufactured by Kuangtai Intelligent Technology Co., Ltd.: 1. Mine-use explosion-proof and intrinsically safe computer; 2. Mine-use intrinsically safe wireless communication alarm infrared camera; 3. Mine-use explosion-proof and intrinsically safe voice alarm; 4. Mine-use intrinsically safe infrared microwave motion detector; 5. Mine-use intrinsically safe wireless dual-mode base station.

[0022] The mining equipment 10 is a winch, transfer machine, tunneling machine or crusher. The mining explosion-proof and intrinsically safe computer 1 is connected to at least one of the winch, transfer machine, tunneling machine or crusher via a communication cable or a mining intrinsically safe wireless dual-mode base station 5.

[0023] The intrinsically safe and explosion-proof computer 1 for mining includes an operating console, which can display the tunnel operation map and personnel location information obtained through UWB precise positioning. When the mining equipment 10 is a winch, the intrinsically safe and explosion-proof computer 1 is connected to the existing winch control console via a pulse encoder, which can realize interlocking alarm and alarm stop.

[0024] When the mining equipment 10 is a tunneling equipment such as a tunneling machine or a crusher, an intrinsically safe infrared microwave motion detector 4 is installed on the body of the tunneling equipment. One set is installed on the left and right sides of the secondary conveyor head, one set is installed on the left and right sides of the secondary conveyor belt 3 meters away from the tail of the tunneling equipment, and one set is installed on the non-pedestrian side of the tunneling equipment. The pedestrian side of the secondary conveyor head is for alarm function, and the other four are for shutdown function; the installation height is 1-1.3m above the ground; the installation direction is towards the sidewall.

[0025] Installing an intrinsically safe infrared microwave motion detector 4 for mining enables linkage functionality at the coal bunker opening. Protective netting is used to protect the coal chute or the upper and lower openings of the coal bunker, with the intrinsically safe infrared microwave motion detector 4 providing primary and intermediate safety standards. The upper opening of the coal bunker is linked to the belt conveyor, with an alarm zone defined within 2m of the protective netting and a stop zone defined within 0.5m. The lower opening of the coal bunker is linked to the coal feeder, with an alarm zone defined within 20m of the coal feeder and a stop zone defined within 10m.

[0026] When the mining equipment 10 is a transfer conveyor, the transfer conveyor in the coal mining face adopts an intrinsically safe infrared microwave motion detector 4 to achieve the basic standard. One intrinsically safe infrared microwave motion detector 4 is installed at the feed inlet of the transfer conveyor to realize the shutdown function. The installation position is 2m outward from the feed inlet of the transfer conveyor. Pedestrians are strictly prohibited from crossing the bridge inward from the installation position.

[0027] The intrinsically safe and explosion-proof power supply 11 is electrically connected to the intrinsically safe wireless communication alarm infrared camera 2, and the intrinsically safe and explosion-proof DC regulated power supply 12 is electrically connected to the switch 7. Both the intrinsically safe and explosion-proof power supply 11 and the intrinsically safe DC regulated power supply 12 are explosion-proof electrical devices designed for explosive gas atmospheres; their discharge energy under extreme conditions will not ignite explosive gases. In underground coal mine operations, where coal dust and other pollutants are present, the use of the intrinsically safe and explosion-proof power supply 11 and the intrinsically safe DC regulated power supply 12 provides enhanced safety. The mining explosion-proof and intrinsically safe power supply, model KDY127, outputs four DC 12V channels. Two of these channels simultaneously power one KBA12WH mining intrinsically safe wireless intercom alarm infrared camera (model 2), with a power supply distance not exceeding 100m. One KXB-127(A) mining explosion-proof and intrinsically safe voice alarm (model 3) outputs one DC 12V channel to power one GURW-12 mining intrinsically safe infrared microwave motion detector (model 4), with a power supply distance not exceeding 100m. The intrinsically safe and explosion-proof voice alarm 3 is connected to the GURW-12 intrinsically safe infrared microwave motion detector 4 for mining via a communication flexible cable to transmit signals. The intrinsically safe and explosion-proof voice alarm 3 can also be replaced with a PJB127 intrinsically safe and explosion-proof LED display alarm screen for mining. The intrinsically safe and explosion-proof DC regulated power supply 12 is model KDW127 / 12B(A), which outputs one DC12V channel to power one KJJH-12 intrinsically safe ring network switch 7 for mining, with a power supply distance of no more than 100m.

[0028] A mobile terminal 13 can also be installed, which is worn by underground workers. The mobile terminal 13 communicates with the WIFI base station 9 via WiFi. The mobile terminal 13 interacts with the mine explosion-proof and intrinsically safe computer 1 through the WIFI base station 9 to realize data query and management functions.

[0029] The mine explosion-proof and intrinsically safe voice alarm 3 can communicate with the WIFI base station 9 via WIFI signal, or it can communicate with the switch 7 via fiber optic cable.

[0030] The UWB base station 8, the intrinsically safe wireless communication alarm infrared camera 2, and the intrinsically safe explosion-proof voice alarm 3 can all send a first alarm signal and a second alarm signal to the intrinsically safe explosion-proof computer 1. Triggered by the first signal, the intrinsically safe explosion-proof computer 1 controls the intrinsically safe explosion-proof voice alarm 3 and / or the intrinsically safe wireless communication alarm infrared camera 2 to sound an alarm. Triggered by the second signal, the intrinsically safe explosion-proof computer 1 controls the mine equipment 10 to shut down.

[0031] The danger zone is defined as a shallow danger zone and a deep danger zone. The detection range of the intrinsically safe wireless communication alarm infrared camera 2 and the intrinsically safe infrared microwave motion detector 4 is located within the shallow danger zone and the deep danger zone. When the mining equipment 10 is in operation, the UWB base station 8 obtains the location information of the UWB positioning card 6 in the roadway and determines whether it is within the danger zone. If it is in the shallow danger zone, it is close to the hazard source and there may be a certain safety risk. In order to ensure personnel safety, the UWB base station 8 sends a first signal to the intrinsically safe explosion-proof computer 1, which then controls the intrinsically safe explosion-proof voice alarm 3 to sound an alarm. If it is in the deep danger zone, there may be a huge safety risk. In order to ensure personnel safety, the UWB base station 8 sends a second signal to the intrinsically safe explosion-proof computer 1, which then controls the mining equipment 10 to shut down.

[0032] Similarly, if the intrinsically safe wireless communication alarm infrared camera 2 detects that personnel are in a shallow danger zone, it sends a first signal to the intrinsically safe explosion-proof computer 1, which then controls the camera to issue an alarm. If the camera detects that personnel are in a deep danger zone, it sends a second signal to the computer, which then controls the equipment 10 to shut down.

[0033] Similarly, if the intrinsically safe infrared microwave motion detector 4 detects that personnel are in a shallow danger zone, it sends a relevant electrical signal to the intrinsically safe explosion-proof voice alarm 3. The intrinsically safe explosion-proof voice alarm 3 then sends a first signal to the intrinsically safe explosion-proof computer 1, which controls the intrinsically safe explosion-proof voice alarm 3 to issue an alarm. If the intrinsically safe infrared microwave motion detector 4 detects that personnel are in a deep danger zone, it sends a relevant electrical signal to the intrinsically safe explosion-proof voice alarm 3. The intrinsically safe explosion-proof voice alarm 3 then sends a second signal to the intrinsically safe explosion-proof computer 1, which also controls the mining equipment 10 to shut down.

[0034] By employing UWB positioning technology, infrared camera detection technology, and infrared microwave detection technology, multiple security alarms are implemented, which can accurately detect personnel, thereby improving detection precision and the accuracy of security alarms.
