[0020] In order to make the technical purposes, technical solutions and beneficial effects of the present application clearer, the technical solutions of the present application will be further described below in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application, that is, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. The components of the embodiments of the present application generally described and shown in the drawings herein can be arranged and designed in various different configurations.

[0021] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0022] The tunneling face environment is complex, the space is small and closed, and there are many equipment, such as fully mechanized mining machine, shuttle car, continuous mining machine, transfer machine, hydraulic support and other large mechanical equipment. In the production process, the illumination is insufficient and the dust amount is large in the coal mine, which seriously affects the vision of the equipment driver; the tunneling equipment is large in size, which will have a large area of blind area; there are many equipment moving frequently and equipment and workers alternating operation in the tunneling face, which is easy to cause equipment injury accidents.

[0023] Therefore, how to improve the safety warning capability of the tunneling face operation in the coal mine, and to the greatest extent protect the life safety of the operation personnel, so as to ensure the safety production of the coal mine, is the key of the protection system research of the mine tunneling equipment.

[0024] The protection system of the mine tunneling equipment of the embodiments of the present application will be described below with reference to the drawings.

[0025] Figure 1 A structure diagram of the protection system of the mine tunneling equipment provided by the embodiments of the present application.

[0026] As Figure 1 shown, the protection system of the mine tunneling equipment includes but is not limited to: at least one configurable thermal imaging camera, at least one infrared heat release sensor, a mine intrinsic safety sound and light electric alarm, a mine intrinsic safety display, an industrial switch, a network control module, a signal processing module and a power module, wherein:

[0027] The configurable thermal imaging cameras are arranged on the mine tunneling equipment, capture infrared radiation of the environment around the mine tunneling equipment, and convert the infrared radiation into visual temperature images, which can be used to set up an electronic fence. The infrared pyroelectric sensors are arranged on the mine tunneling equipment, and detect infrared radiation emitted by personnel or objects entering the electronic fence area in real time based on the pyroelectric effect, so as to trigger a corresponding warning or alarm mechanism. The mine intrinsically safe audible and light alarm is arranged on the mine tunneling equipment, connected with the configurable thermal imaging cameras and the infrared pyroelectric sensors. The configurable thermal imaging cameras transmit the real-time monitored temperature data to the mine intrinsically safe audible and light alarm through wired or wireless means. The infrared pyroelectric sensors convert the detected infrared radiation signals into electrical signals, and transmit the electrical signals to the mine intrinsically safe audible and light alarm through wired or wireless means. The mine intrinsically safe audible and light alarm determines whether personnel or objects enter the preset electronic fence area according to the received signals, and determines whether to send an alarm signal according to a preset threshold. The network control module is connected with the mine intrinsically safe audible and light alarm, and converts the detected infrared radiation, so that subsequent signal processing and analysis can be conveniently performed. The industrial switch is connected with the network control module, and accesses the configurable thermal imaging cameras and the converted infrared radiation, so as to perform remote management and monitoring. The signal processing module is connected with the industrial switch, and obtains the video pictures of the configurable thermal imaging cameras, the infrared radiation, and the alarm signals through the industrial switch. If personnel or objects enter the electronic fence area, a first level warning is triggered, and the alarm signal is sent to the data center of the fully mechanized coal mining face. If the personnel or objects do not leave the electronic fence area after the first level warning, a second level warning is triggered, and the signal processing module executes a corresponding shutdown mechanism of the mine tunneling equipment, for example, the power supply can be turned off, the production line can be stopped, and the like, so as to prevent accidents. At the same time, the data center can also dispatch personnel to the site for intervention. The power module is connected with the configurable thermal imaging cameras, the infrared pyroelectric sensors, the mine intrinsically safe audible and light alarm, the mine intrinsically safe display, the network control module, and the industrial switch, so as to ensure that the components can operate in a stable voltage environment, thereby improving the overall stability and reliability of the protection system of the mine tunneling equipment. The power module is not shown in the drawings. Figure 1

[0028] ​Optionally, as an example, the number of configurable thermal imaging cameras and infrared heat release sensors is four, which are respectively arranged at the front, tail and both sides of the mine tunneling equipment. The configurable thermal imaging camera and infrared heat release sensor at the front of the mine tunneling equipment can monitor the geological conditions of the tunneling face and the front thereof in real time, including potential rock fracture, abnormal ground heat and the like. The configurable thermal imaging camera and infrared heat release sensor at the tail of the mine tunneling equipment can monitor the working area behind the equipment to ensure that personnel or other equipment are not injured or damaged when the equipment moves or adjusts, and can also monitor the waste accumulation during the tunneling process to guide the cleaning work. The configurable thermal imaging camera and infrared heat release sensor at both sides of the mine tunneling equipment can cover the side of the tunneling working face to effectively reduce the monitoring blind area.

[0029] It should be noted that the number of configurable thermal imaging cameras and infrared heat release sensors includes but is not limited to four, and can also be more than four, as long as the temperature distribution on the surface of the object can be captured and displayed in real time, the potential risks of the mine environment can be obtained in time, and the visual blind area can be minimized. The number of any configurable thermal imaging cameras and infrared heat release sensors is applicable, and is not limited to the present embodiment.

[0030] Optionally, the mine intrinsic safety type sound and light alarm is installed on the top of the mine tunneling equipment, which can ensure that the sound and light alarm signal emitted after receiving the real-time monitored temperature data and infrared radiation signal can cover a wider area, improve the coverage and effectiveness of the alarm, and thus effectively reduce the risk of accidents.

[0031] Optionally, the electronic fence area includes an alarm area and a shutdown area, and different safety protection levels are taken according to different detection conditions of the intruding object. If the intruding object is detected in the alarm area, the mine intrinsic safety type sound and light alarm sends an alarm signal, and transmits the alarm signal to the data center through the network control module, the industrial switch and the signal processing module. If the intruding object is detected in the shutdown area, the signal processing module will trigger the mine tunneling equipment to shut down based on the alarm signal to prevent potential safety accidents.

[0032] Optionally, as an example, the network control module converts the high-low level signal output by the infrared pyroelectric sensor into an Ethernet signal. The infrared pyroelectric sensor works based on the pyroelectric effect principle, that is, when infrared radiation irradiates on the pyroelectric material, it will cause the relative displacement of the electric charge center inside the material, thereby generating an electric signal, which is usually a high-low level signal, indicating that an intruder has entered the electronic fence area. The network control module can convert the high-low level signal output by the infrared pyroelectric sensor into an Ethernet signal to ensure that the data of the infrared pyroelectric sensor can be transmitted on the Ethernet, thereby realizing remote monitoring and data processing. The conversion process involves signal amplification, filtering, encoding and other steps to ensure the accuracy and stability of the signal; the converted signal is packaged into an Ethernet data packet and sent to the network through the Ethernet interface. These data packets can contain the identity information of the infrared pyroelectric sensor, detection time, detection results, etc.

[0033] Optionally, as an example, the communication protocol adopted by the industrial switch includes industrial Ethernet protocol, field bus protocol, CAN bus protocol, wherein the industrial Ethernet protocol provides end-to-end communication services and can be used to transmit alarm signals, device status information and other key data; the field bus protocol can be used to connect mine tunneling equipment, infrared pyroelectric sensors, mine-used intrinsically safe sound and light electric alarm, etc., to realize real-time data transmission and monitoring; the CAN bus can perform high-speed data transmission, etc.

[0034] It should be noted that the setting form of the communication protocol should be selected according to the specific use scenario.

[0035] Optionally, the signal processing module includes a workstation computer and a cloud computing platform, wherein the workstation computer and the cloud computing platform can obtain the video picture of the configurable thermal imaging camera and the infrared radiation of the infrared pyroelectric sensor, and through a pre-set algorithm and model, the system can automatically identify abnormal conditions in the monitoring area, such as temperature changes, human activities, etc.; when an abnormal condition occurs, the workstation computer and the cloud computing platform will trigger an alarm event, the information of the alarm event includes alarm time, place, type and other key information, and the key information is sent to the data center; at the same time, the workstation computer and the cloud computing platform will also record the alarm event in the database for subsequent query and analysis, for backtracking and reproduction.

[0036] Optionally, as an example, the signal processing module and the industrial switch are connected through an industrial ring network topology, and the signal processing module and the industrial switch form a closed loop, which can quickly recover communication when the network fails, ensuring the stability and continuity of data transmission, thus having high redundancy.

[0037] Optionally, as an example, the input voltage of the power module is 127V, and the output voltage of the power module includes 12V and 18V, wherein each configurable thermal imaging camera, each infrared heat release sensor, the mine intrinsic safety display, the network control module and the industrial switch are powered by 12V; and the mine intrinsic safety sound and light alarm is powered by 18V.

[0038] In summary, the protection system of the mine tunneling equipment according to the embodiments of the present application can detect the intruding object in the environment with high dust and low visibility, greatly reducing the visual blind area, by configuring the electronic fence area by the configurable thermal imaging camera, setting the electronic fence area of the mine tunneling equipment periphery by the infrared heat release sensor, setting the electronic fence area of the mine intrinsic safety sound and light alarm, setting the corresponding alarm shutdown mechanism according to the actual situation of the electronic fence by the signal processing module, and greatly reducing the accident risk; enhancing the intuitiveness and safety of the operation by setting the mine intrinsic safety display to display the thermal imaging picture and the visible light picture; realizing the network transmission of the data by the network control module and the industrial switch; and facilitating the remote monitoring and management by the signal management module which can receive the thermal imaging picture and the alarm signal in real time, and significantly improving the safety level of the operation in the mine.

[0039] Finally, it should be noted that the above embodiments are only used for illustration but not limit the technical solutions of the present application, any equivalent replacement, modification or partial replacement of the present application without departing from the spirit and scope of the present application should be covered in the protection scope of the claims of the present application.
