Description

Technical Field

[0001] The utility model relates to the technical field of coal mine safety prevention areas, in particular to an electronic fence system for dangerous operation areas underground in coal mines. Background Technique

[0002] In recent years, coal mine production safety accidents have occurred frequently. In order to ensure the safety of the coal mine mining process and realize real-time monitoring of each production link, a large number of sensors are usually arranged in operating equipment and operating sites for data collection, and a control platform is used for unified management. Once a fault is detected, an alarm reminder will be immediately sent through the control platform.

[0003] However, the existing control platforms still have the following defects in actual application:

[0004] First, the existing control platforms often include multiple subsystems, such as safety management, production management, video monitoring, and fire alarm, etc. These subsystems lack linkage, are independent of each other, cannot share data, increase the complexity of management, reduce management efficiency, and make the false alarm rate of the system relatively high, affecting production.

[0005] Second, the integrated control platform lacks a personnel control function. Some production areas are dangerous for non-professional personnel, and production accidents are extremely likely to occur due to the entry of personnel by mistake.

[0006] Third, the integrated control platform lacks intelligence and relies on manual management. Therefore, for the handling of emergencies, it cannot respond in a timely manner. For this reason, an electronic fence system for dangerous operation areas underground in coal mines is proposed. Summary of the Invention

[0007] The purpose of the utility model is to provide an electronic fence system for dangerous operation areas underground in coal mines to solve the problems put forward in the above background technique.

[0008] To achieve the above purpose, the utility model provides the following technical solution: An electronic fence system for dangerous operation areas underground in coal mines, including a core switch, the core switch is wirelessly connected to a monitoring and management display mechanism and an intrinsically safe switch respectively, the intrinsically safe switch is wirelessly connected to a fixed monitoring component and a mobile monitoring component respectively, and the fixed monitoring component and the mobile monitoring component form an industrial ring network above and below the ground with the monitoring and management display mechanism through the core switch and the intrinsically safe switch.

[0009] Among them, the monitoring and management display mechanism includes a display, an AI management server, and an electronic fence monitoring module.

[0010] As a further optimization of this technical solution: A core switch is provided to play a key role in connecting, managing, and optimizing data streams in the overall architecture. It is crucial for the normal operation of the entire system and provides guarantee for its stable operation. Meanwhile, it can accelerate data exchange within a large local area network, and an intrinsically safe switch is used to connect the operating lines and other interconnected units.

[0011] As a further optimization of this technical solution: Monitor information is fed back through a display, and a powerful computing ability is provided by an AI management server to support large-scale training, inference, and analysis tasks of artificial intelligence applications, ensuring efficient and stable processing of massive data, thereby providing a reliable AI solution. Meanwhile, the electronic fence monitoring module can be flexibly set and managed. By setting an electronic fence for a specific area, once an activity occurs in this area, it will be immediately monitored and an alarm will be given, promptly notifying relevant personnel for handling. Thus, through the above monitoring methods, the real-time monitoring ability for specific areas is greatly improved, providing strong support for safety management.

The intrinsically safe switch is wirelessly connected to the AI camera group, and the AI camera group is wirelessly connected to the audible and visual alarm group. Image acquisition, AI analysis, and alarm signal output are carried out through the AI camera group, and the set audible and visual alarm group gives warnings to people in the form of sound and light signals, informing that there is a dangerous situation nearby.

They establish connections between the mobile communication network and mobile devices, supporting voice calls, data transmission, and other mobile network services. And through its antenna system, the base station can significantly expand the coverage area of the wireless network, ensuring that the communication network can be accessed within a wider geographical area. And the access gateway is used to improve network performance and efficiency and achieve communication effects between components. At this time, the audible and visual alarm gives warnings to people in the form of sound and light signals, informing that there is a dangerous situation nearby.

[0015] As a further preference of the technical solution: The access gateway is also electrically connected to a pyroelectric sensor group and a thermal imager group respectively through wires. The pyroelectric sensor group is set for human detection, personnel activity monitoring, and sensing the temperature change of surrounding objects to detect abnormal situations, while the thermal imager group is set for monitoring equipment fault points and analyzing the intrusion situation of personnel by fusing with the pyroelectric sensor group.

[0016] As a further preference of the technical solution: The access gateway is also electrically connected to an intrinsically safe display and a UWB sub-station respectively through wires. The intrinsically safe display is used to provide safe and reliable signals for the normal operation of staff, vehicles, and relevant equipment in the mining mine, while the UWB sub-station is used for high-precision positioning.

And through its antenna system, the base station can significantly expand the coverage area of the wireless network to ensure that the communication network can be accessed within a wider geographical area. And the provided access gateway 10 is used to improve network performance and efficiency and achieve the communication effect between components. At this time, the provided audible and visual alarm 15 is a safety device, which mainly gives warnings to people in the form of sound and light signals to inform that there are dangerous situations nearby.

[0040] In this embodiment, specifically: the set wireless base station 9 uses the mine intrinsically safe wireless base station KT767-F, which has the communication functions of a 100M Ethernet optical port, an RJ11 interface, and a 100M Ethernet electrical port, and has a wireless communication function.

The set audible and visual alarm 15 also uses the mine intrinsically safe audible and visual alarm KXB18.

[0041] In this embodiment, specifically: the access gateway 10 is also electrically connected to a pyroelectric sensor group 11 and a thermal imager group 12 through wires respectively. The set pyroelectric sensor group 11 is used for human detection, personnel activity monitoring, and sensing the temperature change of surrounding objects to realize the detection of abnormal situations. The set thermal imager group 13 is used for monitoring equipment fault points on the one hand, and on the other hand, it analyzes the situation of personnel breaking in by fusing with the pyroelectric sensor group 11;

[0042] Among them, it should be further explained that the set pyroelectric sensor group 11 can also assist in detecting blind spots.

[0043] In this embodiment, specifically: the set pyroelectric sensor group 11 uses the mine pyroelectric infrared sensor GUR6(A), and the set thermal imager group 12 uses the mine intrinsically safe thermal imaging camera KBA12R;

[0044] Among them, the number of the mine pyroelectric infrared sensors GUR6(A) and the mine intrinsically safe thermal imaging cameras KBA12R used is no less than four.

[0045] In this embodiment, specifically: the access gateway 10 is also electrically connected to an intrinsically safe display 13 and a UWB sub-station 14 through wires respectively. The set intrinsically safe display 13 is used to provide safe and reliable signals for the normal operation of the staff, vehicles, and relevant equipment in the mining mine. The set UWB sub-station 14 is used for high-precision positioning. It obtains the position information of people or objects within a certain space range, so as to be able to understand the position of key objects in real time, accurately record the movement behavior trajectory of key objects, and thus realize the regular inspection, real-time monitoring of equipment points, and warning of dangerous areas, reminding visitors and other non-related personnel not to approach dangerous areas.

[0046] In this embodiment, specifically: the set UWB sub-station 14 has the advantages of strong penetration, low power consumption, good anti-multipath effect, high security, low system complexity, and can provide precise positioning accuracy. It can obtain good positioning effects in certain occasions, and can also achieve higher accuracy when performing ranging, positioning, and tracking.

[0047] In this embodiment, specifically: the intrinsically safe display 13 is a mining intrinsically safe display screen PH12, which has a display function, including an Ethernet electrical signal interface to communicate with other devices, and has a built-in APP application software, which can display thermal imaging and pyroelectric sensor signals, and at the same time connect to display personnel positioning approach alarm signals.

[0048] Working principle: When the fixed monitoring component is in operation, the on-site video images are collected through the mine intrinsically safe image processing camera, mine intrinsically safe sound and light alarm and mine cast-in-place intrinsically safe DC regulated power supply. The intrusion of personnel is identified through the AI ​​intelligent analysis and recognition algorithm. The video images can be divided into alarm areas of different levels by using the camera's built-in AI recognition algorithm. That is, when a person enters the first-level alarm area (far away), the alarm is immediately triggered and captured, and the alarm information is output to link the sound and light alarm 15 for sound and light voice alarm. When a person enters the second-level alarm area (closer), the alarm signal is output to the relevant control device to control the equipment to lock and shut down. The signal of the mine intrinsically safe image processing camera is transmitted to the underground intrinsically safe switch 5 through the optical cable to upload the data to the ground management software.

[0049] When the mobile monitoring component is running, the installed mine intrinsically safe thermal imaging camera and mine pyroelectric infrared sensor sense the situation of people approaching around the excavation equipment. The mine intrinsically safe thermal imaging camera divides the secondary electronic fence control area from the front and back, and the mine pyroelectric infrared sensor assists in detecting blind spots. Among them, the mine intrinsically safe thermal imaging camera and the mine pyroelectric infrared sensor are connected to the mine explosion-proof and intrinsically safe access gateway. At this time, the mine explosion-proof and intrinsically safe access gateway collects the on-site thermal map screen, and uses the AI ​​intelligent analysis and recognition algorithm to detect people intruding into the screen. For identification, the mine explosion-proof and intrinsically safe access gateway simultaneously accesses the mine pyroelectric infrared sensor data through the switch quantity, and analyzes the intrusion of personnel through the fusion of the mine intrinsically safe thermal imaging camera and the mine pyroelectric infrared sensor, so as to realize the division of alarm areas of different levels, that is, when a person enters the first-level alarm area (far away), the alarm is immediately captured, and the alarm information is output to link the sound and light alarm 15 to sound and light voice alarm; when a person enters the second-level alarm area (closer distance), the alarm signal is output to the relevant control device to control the equipment to lock and shut down;

[0050] At this time, the mine flameproof and intrinsically safe access gateway has switch alarm data output by the personnel positioning UWB substation 14 that can be accessed, and the switch data of the personnel positioning UWB substation 14 can be integrated and accessed, and the operation room of the tunneling equipment is equipped with a mine intrinsically safe display screen and a mine intrinsically safe sound and light alarm. The mine intrinsically safe display screen is installed with APP application software, which can communicate with the mine flameproof and intrinsically safe access gateway to display the mine intrinsically safe thermal imaging camera, mine pyroelectric infrared sensor, and personnel positioning alarm data in real time on site. When a person breaks into the designated alarm area, the mine flameproof and intrinsically safe access gateway outputs a control signal to trigger the sound and light alarm 15 to give a sound and light alarm notification;

[0051] Among them, the "electronic fence" data of the equipment can be wirelessly received through the mine intrinsically safe wireless base station. The data of the wireless base station 9 is transmitted to the mine intrinsically safe optical terminal through the RJ11 interface cable (can transmit 2KM), and its data enters the industrial ring network above and below the well, and transmits the data to the ground monitoring center;

[0052] It should be further explained that the fixed monitoring components can be used in places such as belt conveyors, coal mining faces, coal bunkers, coal chutes and closed walls, while the mobile monitoring components can be used in tunneling face equipment, including tunneling machines, anchor boring machines and bolting machines. At the same time, the fixed monitoring components and mobile monitoring components can be operated in conjunction or used separately.

[0053] 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.
