[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0025] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It is understood that in order to ensure the safety of mine operations and prevent accidents such as fires, this application provides an automated thermal imaging detection device for mines. This automated detection device rapidly integrates infrared technology, image processing technology, microcomputer technology and coal mine explosion-proof technology to achieve mine safety monitoring.

[0027] The mining thermal imager provided in this application, combining microcomputer technology and automation technology, provides mining explosion-proof vehicles with a practical means to scan road conditions and the working environment, displaying the images intuitively on the vehicle's display screen, and to assess the road conditions and working environment. To better understand the mining thermal imager provided in this application, a detailed description is provided below with reference to the accompanying drawings.

[0028] Figure 1 The diagram shown is a structural schematic of a mining thermal imager according to some embodiments of this application, such as... Figure 1 As shown, the mining thermal imager may specifically include:

[0029] Housing, thermal imaging lens, and controller.

[0030] The thermal imaging lens and the controller are housed within the housing.

[0031] The controller is electrically connected to the lens of the thermal imager. The camera is used to collect infrared scanning data of the detection area and transmit it to the controller.

[0032] Specifically, such as Figure 1 As shown in the embodiments of this application, the mining thermal imager may include a housing, a controller inside the housing, and a thermal imaging lens.

[0033] The controller and the thermal imaging lens can be installed inside the housing, which protects them.

[0034] The controller is electrically connected to the thermal imaging lens, enabling the transmission of infrared scan data of the detection area electrically acquired by the thermal imaging lens to the controller during actual use, i.e., when the mining thermal imager is placed in the monitoring position.

[0035] For example, such as Figure 4 As shown, in actual work, this mining thermal imager can be installed on work vehicles as a vehicle-mounted device to perform mobile monitoring of the work area in the mine.

[0036] Alternatively, it can be fixedly installed at a monitoring point to conduct real-time monitoring of the detection area or monitoring point.

[0037] It can use a configured thermal imaging lens to perform real-time infrared radiation scanning of the working environment of the detection area, so as to accurately detect the detection area, such as the on-site environment or complex road conditions, and upload the scanned infrared data to the controller, such as a microcontroller.

[0038] In this embodiment of the application, during fault investigation at a mining site, the thermal imaging camera of the mining thermal imager can be used to monitor changes in the mining environment in real time, promptly identifying potential hazards such as coal seam spontaneous combustion, overheating of mechanical equipment, and road malfunctions. Specifically, the mining thermal imager in this application acquires images of the detection area through a thermal imaging lens, enabling detection of hazardous areas without contact with the object being tested, while ensuring personnel safety. This improves detection efficiency and safety, and enhances the field applicability of the mining thermal imager.

[0039] Optionally, in some embodiments of this application, the controller may integrate a communication module to enable communication with other devices.

[0040] That is, the controller can also transmit the collected infrared data to the communication module, and then provide it to the host computer for data processing or the display device for image display through the communication module.

[0041] The controller can use STMicroelectronics' STM32F1 series chips.

[0042] In practice, this controller can be developed and use high-speed communication protocols such as SPI or TCP / IP to perform high real-time data interaction with the vehicle display. It can also communicate with controllers from other manufacturers, such as vehicle controllers, through the open-source protocol CANOpen. Furthermore, it can preset parameters to perform alarm and shutdown protection operations based on existing processing modes.

[0043] Optionally, in some embodiments of this application, the thermal imaging lens may be a long-wave infrared (LWIR) thermal imaging lens, which has a strong ability to penetrate smoke and dust and has high resolution, meeting the needs of harsh mining environments and accurate detection of complex road conditions.

[0044] Optionally, such as Figure 2As shown, in some embodiments of this application, the thermal imaging lens can be fixedly mounted on the circuit board of the controller to ensure internal structural stability.

[0045] Optionally, such as Figure 2 As shown, in some embodiments of this application, the housing includes a front protective shell for the camera, a rear protective shell for the camera, and a rear cover plate for the camera.

[0046] The front protective shell of the camera and the rear protective shell of the camera, as well as the rear protective shell of the camera and the rear cover plate of the camera, can be snapped together or threaded together; this application does not limit this.

[0047] Optionally, in some embodiments of this application, the outer casing can be made of high-strength aluminum alloy material and the surface can be treated with explosion-proof material, so that the outer casing has good explosion-proof performance and can effectively resist high temperature, humidity and flammable and explosive substances in the mining area.

[0048] In addition, the enclosure has an IP54 protection rating and can be equipped with internal sealing gaskets to prevent dust and moisture from entering, ensuring the safe and stable operation of internal electronic components.

[0049] Optionally, in some embodiments of this application, such as Figure 2 As shown, in order to ensure the normal use of the structure, the front protective shell of the camera is provided with a light-transmitting hole.

[0050] The light-transmitting hole may include a circular hole corresponding to the infrared lens, and rectangular holes on both sides of the circular hole, and tempered glass may be placed in the rectangular holes.

[0051] Optionally, such as Figure 2 As shown, to ensure the structural stability of the mining imager and improve its sealing performance, a lens rubber ring can be installed between the infrared lens and the circular aperture to protect the lens's safety. A sealing gasket is also installed on the outside of the tempered glass.

[0052] In addition, in some embodiments of this application, a waterproof ring is provided between the front protective shell and the rear protective shell of the camera to ensure the airtightness of the structure.

[0053] Optionally, such as Figure 2 As shown, a fixed bracket is provided on the rear protective shell of the camera to facilitate the installation and use of the mining thermal imager.

[0054] The mounting bracket is equipped with camera mounting standard parts, which allows the mining thermal imager to be stably installed on the work vehicle or other monitoring locations.

[0055] Optionally, such as Figure 2As shown, the rear cover of the camera has a through hole for inserting an aviation connector. The aviation connector can be secured to the rear cover using a fixing nut, ultimately enabling electrical connection between the mining camera and other equipment such as a host computer. For example, the mining thermal imager can be plugged into the interface of the vehicle's onboard controller via the aviation connector to achieve electrical connection with the onboard controller.

[0056] Optionally, in some embodiments of this application, when the mining thermal imager is placed on a work vehicle, i.e., when the host computer is a vehicle-mounted controller, the controller in the mining thermal imager can communicate with the vehicle-mounted controller via CAN, and can communicate with the vehicle-mounted display screen via Ethernet or WiFi, so that the vehicle-mounted display screen can display the detection image corresponding to the infrared scanning data.

[0057] That is, Figure 3 and 4 As shown, when the mining thermal imager is working, after receiving infrared data, the controller can transmit the corresponding thermal imaging image, i.e., thermal imaging image information, to the display screen for real-time display, such as real-time display of detected obstacles.

[0058] For example, in some embodiments of this application, when the mining thermal imager is installed on a vehicle as an in-vehicle device, the communication module in the controller splits the data transmitted from the controller and can transmit it to the in-vehicle controller and the in-vehicle display screen through the CAN and Ethernet interfaces respectively.

[0059] The CAN interface is used to connect to the vehicle controller and transmit alarm and shutdown information to the vehicle controller so that the vehicle controller can control the vehicle to perform corresponding actions, such as stopping the vehicle.

[0060] Alternatively, in some other embodiments of this application, the Ethernet port is connected to the display screen. The communication module not only transmits alarm shutdown information and real-time images from the thermal imager to the display screen via the Ethernet port, but the display screen can also send parameter configuration commands to the communication module via the Ethernet port, which are ultimately transmitted to the controller. Optionally, in some embodiments of this application, such as Figure 5 As shown, the vehicle-mounted display screen can be configured with a real-time display page, a configuration page, and an alarm page. That is, the display results can be divided into three screens: a thermal imager parameter configuration screen, a real-time thermal imager screen, and a thermal imager alarm shutdown screen.

[0061] The specific parameters of the thermal imager can be configured through the configuration page, such as alarm thresholds and shutdown thresholds.

[0062] In some embodiments of this application, the controller parameters can be configured through a display parameter configuration interface, such as an in-vehicle display screen.

[0063] For example, the enable and threshold of digital and analog signals can be configured to meet the needs of various on-site situations.

[0064] The real-time image displayed by the thermal imager shows the obstacles detected in real time, and makes a rough judgment on the type of obstacle based on its shape and imaging temperature.

[0065] The alarm shutdown screen displays alarm information derived from real-time detection results of the thermal imager combined with preset parameters within the microcontroller.

[0066] It is understood that the mining thermal imager in this application has the following effects:

[0067] Real-time monitoring: It can monitor temperature changes in the mining environment in real time and promptly detect potential hazards, such as spontaneous combustion of coal seams and overheating of mechanical equipment.

[0068] Easy to use: This infrared thermal imaging technology is designed specifically for explosion-proof vehicles in mines. When used in conjunction with the matching UWB (Underground Wi-Fi) electronic fence technology, it can be put into use after standard integrated installation.

[0069] Non-contact detection: It does not require contact with the object being tested, and can detect dangerous areas while ensuring personnel safety, thus improving detection efficiency and safety.

[0070] Visual parameter configuration: This mining thermal imager can be configured through the matching display screen, which simplifies the parameter configuration process and improves the field applicability of the mining thermal imager.

[0071] Multi-control source interaction: This thermal imager adopts an integrated design concept, so that the vehicle controller, display screen and thermal imager are no longer isolated individuals. There is real-time data interaction between the various modules, which can greatly improve the automation and intelligence level of the vehicle itself.

[0072] Explosion-proof safety: The explosion-proof casing enables stable operation in the harsh environment of the mining area, reducing safety hazards caused by environmental factors, which is often difficult to achieve in traditional equipment.

[0073] These advantages enable the new mining thermal imager to perform exceptionally well in the automated control of explosion-proof mining vehicles, significantly improving the vehicle's automation level and safety.

[0074] On the other hand, some embodiments of this application provide a mining monitoring system, which may include a mining thermal imager as described in the above embodiments, and a host computer.

[0075] The mining thermal imager interacts with the host computer through its internal communication module. The controller in the mining thermal imager receives infrared data or transmits the processed infrared data to the host computer, enabling the host computer to take corresponding protective measures based on the received data.

[0076] If the mining thermal imager is a vehicle-mounted device, the host computer can be a vehicle controller, enabling the vehicle controller to perform operations such as stopping operation based on the received infrared data.
