Description

Technical Field

[0001] This utility model relates to the field of dust control technology, and in particular to a roadside device and a water spraying dust suppression system for open-pit mines. Background Technology

[0002] Open-pit mines, as an important method of mineral resource development, inevitably generate large amounts of dust during key operations such as blasting, excavation, transportation, and crushing. This dust mainly consists of rock fragments and soil particles, which are lifted and suspended in the air during operations, forming dust pollution that poses potential hazards to the environment and human health. The geographical characteristics of open-pit mines, such as their open terrain and strong winds, further exacerbate the dust dispersion problem, making dust pollution more widespread and having a more profound impact.

[0003] The direct impact of dust pollution on mining operations manifests in reduced visibility. In environments with high concentrations of dust, the normal operation of autonomous driving systems is severely disrupted. Because dust reduces visibility, autonomous driving systems struggle to accurately capture information about their surroundings and determine their own position. This not only increases the risk of collisions between autonomous vehicles and obstacles, other vehicles, or personnel, but may also cause unmanned mining trucks to deviate from their planned paths and fail to reach their destinations accurately. Furthermore, dust can limit the speed of mining trucks, thereby reducing the overall transportation efficiency of the mine.

[0004] Currently, open-pit mines typically control dust by deploying water spray pipes and nozzles, using multiple nozzles to suppress dust. However, existing dust control methods lack visibility monitoring, and the operation of the spraying system is manually controlled. This often involves prolonged operation after manual activation, leading to wasted water resources. Furthermore, once activated, the spraying is applied over a wide area, making it impossible to target specific areas, resulting in poor dust suppression and wasted resources. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to enable readers to better understand this utility model. However, the technical solutions claimed by this utility model can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0021] To facilitate understanding of the embodiments of this application, relevant content on dust control in open-pit mines will be introduced first.

[0022] Open-pit mines, as an important method of mineral resource development, inevitably generate large amounts of dust during key operations such as blasting, excavation, transportation, and crushing. This dust mainly consists of rock fragments and soil particles, which are lifted and suspended in the air during operations, forming dust pollution that poses potential hazards to the environment and human health. The geographical characteristics of open-pit mines, such as their open terrain and strong winds, further exacerbate the dust dispersion problem, making dust pollution more widespread and having a more profound impact.

[0023] The direct impact of dust pollution on mining operations manifests in reduced visibility. In environments with high concentrations of dust, the normal operation of autonomous driving systems is severely disrupted. Because dust reduces visibility, autonomous driving systems struggle to accurately capture information about their surroundings and determine their own position. This not only increases the risk of collisions between autonomous vehicles and obstacles, other vehicles, or personnel, but may also cause unmanned mining trucks to deviate from their planned paths and fail to reach their destinations accurately. Furthermore, dust can limit the speed of mining trucks, thereby reducing the overall transportation efficiency of the mine.

[0024] Currently, open-pit mines typically control dust by deploying water spray pipes and nozzles, using multiple nozzles to suppress dust. However, existing dust control methods lack visibility monitoring, and the operation of the spraying system is manually controlled. This often involves prolonged operation after manual activation, leading to wasted water resources. Furthermore, once activated, the spraying is applied over a wide area, making it impossible to target specific areas, resulting in poor dust suppression and wasted resources.

[0025] Example 1: The present invention relates to a roadside device for open-pit mines.

[0026] Compared to existing technologies, the implementation of this utility model involves distributing roadside equipment at different locations in the open-pit mine. This allows for the collection of visibility information from various roads using an information acquisition module, enabling dust monitoring across the entire mining area. Simultaneously, a positioning module accurately provides location information for each roadside device, pinpointing specific locations with poor visibility. This information is then transmitted to a cloud server via a communication module, which controls the corresponding water spraying devices to activate dust suppression operations. This precise dust suppression not only ensures effective dust control but also makes efficient use of water resources and improves visibility, thereby guaranteeing safety in the mining area.

[0027] The following is a detailed description of the implementation details of the roadside equipment in this embodiment. The following content is only for the convenience of understanding and is not necessary for implementing this solution.

[0028] The present invention provides a roadside device for open-pit mines, such as... Figure 1 As shown, multiple roadside devices 1 are provided and distributed in different locations of the open-pit mine, and multiple roadside devices 1 are connected to a cloud server 2. The cloud server 2 is connected to multiple water spraying devices 3 distributed in different locations. In this embodiment, the roadside device 1 includes an information acquisition module 4, a positioning module 5, a control module 6, and a communication module 7. In this embodiment, the water spraying device 3 is a water truck. The number of water trucks can be reasonably configured based on the size of the open-pit mine to facilitate water spraying and dust suppression treatment in different locations of the open-pit mine.

[0029] The information acquisition module 4 is used to collect road visibility information; the positioning module 5 is used to collect the positioning information of the roadside equipment 1; the control module 6 is connected to the information acquisition module 4 and the positioning module 5, and is used to receive visibility information and positioning information; one end of the communication module 7 is connected to the control module 6, and the other end is connected to the cloud server 2; the communication module 7 is used to send the visibility information and positioning information fed back by the control module 6 to the cloud server 2, so that the cloud server 2 can send a watering and dust suppression signal to the watering device 3 at the location corresponding to the positioning information for execution.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, the information acquisition module 4 includes an image acquisition module 41 and a laser dust sensor 42. The image acquisition module 41 is used to acquire image information of the road; the laser dust sensor 42 is used to acquire the concentration of dust particles in the air. Both the image acquisition module 41 and the laser dust sensor 42 are connected to the control module 6, and multiple image acquisition modules 41 and laser dust sensors 42 can be configured to acquire visibility information from different directions. In this embodiment, four image acquisition modules 41 and three laser dust sensors 42 are configured to acquire image information from four different directions using four image acquisition modules, and the laser angles of the three laser dust sensors 42 are used to form a 360° laser dust monitoring coverage area without blind spots, ensuring comprehensive visibility monitoring.

[0031] Furthermore, the roadside equipment 1 is provided with several first physical interfaces for connecting the image acquisition module 41 and second physical interfaces for connecting the laser dust sensor 42. That is, the image acquisition module 41 and the laser dust sensor 42 can be connected through the first and second physical interfaces to form a detachable accessory on the roadside equipment 1, so as to install the corresponding number of image acquisition modules 41 on the laser dust sensor 42 as needed, and the image acquisition module 41 can be independently removed from the laser dust sensor 42 for maintenance or centralized data collection, etc., improving the convenience and flexibility of operation and use.

[0032] Specifically, in this case, the control module 6 of roadside equipment 1 uses Jetson Orin NX. Jetson Orin NX is NVIDIA's latest edge AI computing module, boasting up to 100 TOPS of AI performance and adjustable power between 10W and 25W. It offers three times the performance of NVIDIA Jetson AGX Xavier and five times the performance of NVIDIA Jetson Xavier NX. The Jetson Orin NX 16GB module utilizes NVIDIA Ampere architecture GPUs, next-generation deep learning and vision accelerators, high-speed I / O, and fast memory bandwidth, supporting multiple AI application workflows and suitable for advanced applications such as natural language understanding, 3D perception, and multi-sensor fusion. All Jetson Orin modules run the globally standard NVIDIA AI software stack, and the Jetson partner ecosystem supports various carrier boards and peripherals for the Jetson Orin NX 16GB module, such as sensors, cameras, and connectivity modules (5G, 4G, Wi-Fi).

[0033] Based on this, the first material interface and the second material interface are located on the control module 6. Specifically, the image acquisition module 41 includes a camera 411, which is connected to the Jetson Orin NX module via a DS90UB954-Q1 connector. CSIA_CLK_P / N is the clock line, and CSIA_D0_P / N and CSIA_D1_P / N are the data lines. These interfaces, CSIA_CLK_P / N, CSIA_D0_P / N, and CSIA_D1_P / N, together form the physical interface for connecting the camera 411. The DS90UB954-Q1 connector serves as the interface between the Jetson Orin NX module and the camera 411. This receiver supports data rates up to 1.5Gbps and conforms to the MIPI CSI-2 v1.2 specification. Multiple laser dust sensors 42 include PM3003S, PM3006S, PM3003Q, and PM3003X from Sifang Optoelectronics. In this solution, the PM3003Q dust sensor is used as an example, and it is connected to the Jetson Orin NX via a UART interface.

[0034] Furthermore, such as Figure 4As shown, the image acquisition module 41 provided in this embodiment includes a camera 411 and a cleaning mechanism 412 disposed on the camera 411. The cleaning mechanism 412 is used to clean the dirt on the camera 411. The cleaning mechanism 412 can be a blower and a nozzle working together. The nozzle is connected to the air outlet of the blower, so that the airflow is sprayed through the nozzle towards the acquisition lens of the camera 411 used to acquire images, thereby blowing away the dust on the lens and avoiding the influence of dust and other impurities on the lens when acquiring images.

[0035] Furthermore, the positioning module 5 provided in this embodiment includes a GPS module, specifically an SKG123S. The SKG123S has a CEP50 (50% probability error) of less than 1.7 meters under open sky conditions. The Jetson Orin NX module connects to the SKG123S via an SPI interface. The SKG123S has fast startup capabilities, with a cold start time of 28 seconds and a warm start time of less than 1 second, enabling it to quickly provide positioning services.

[0036] Furthermore, the communication module 7 provided in this embodiment includes V2X, WiFi, ZigBee, and mobile communication modules. The V2X communication board is connected to the Jetson Orin NX module via a USB 3.2 interface, the WiFi module is connected to the Jetson Orin NX module via a PCIe interface, the ZigBee module in this solution is a CC2530 module, the CC2530 module is connected to the Jetson Orin NX module via a UARI interface, the 3G communication module 7 is connected to the Jetson Orin NX module via a PCIe interface, the 4G communication module 7 is connected to the Jetson Orin NX module via an Ethernet interface, and the 5G communication module 7 is connected to the Jetson Orin NX module via an M.2 Key E interface.

[0037] In some embodiments, the roadside equipment 1 further includes a heat dissipation module 8 and a temperature and humidity sensor 9. The heat dissipation module 8 is connected to the control module 6. The temperature and humidity sensor 9 is used to detect the ambient temperature and humidity information of the roadside equipment 1, and is also connected to the control module 6. The control module 6 is used to receive the temperature and humidity information fed back by the temperature and humidity sensor 9, and to send control signals to the heat dissipation module 8. By monitoring the temperature and humidity information of the roadside equipment 1 through the temperature and humidity sensor 9, the heat dissipation module 8 can effectively dissipate heat from the roadside equipment 1 in a timely manner, ensuring the stable operation of the equipment.

[0038] Furthermore, at least two temperature and humidity sensors 9 are configured to be installed at different locations on the roadside equipment 1 to collect temperature and humidity information of different areas of the roadside equipment 1; the heat dissipation module 8 includes at least two cooling fans to dissipate heat to different areas respectively.

[0039] like Figure 3 As shown, in this embodiment, the control module 6 is configured as a Jetson Orin NX module, and the temperature and humidity sensor 9 is connected to the Jetson Orin NX module via GPIO pins. The fan is connected to the Jetson Orin NX module via PWM pins. The temperature and humidity sensor 9 consists of temperature and humidity chips. The temperature and humidity sensor 9 includes, but is not limited to, SHT20, SHT3x, and BME280 sensors. The temperature and humidity chips can simultaneously detect ambient temperature and humidity information. Multiple temperature and humidity chips can be installed on the Jetson Orin NX module baseboard to collect temperature information from different areas. The temperature and humidity detection unit is used for heat dissipation regulation. When the temperature in a certain area is too high, the system can drive the fan for rapid heat dissipation, allowing the system to operate at a lower temperature to avoid the system malfunctioning under high-temperature conditions.

[0040] In some embodiments, the roadside device 1 is equipped with a main power module and a backup power interface connected to the control module 6. The backup power interface is connected to a backup battery 10 to supply power to the roadside device 1 during power outages or restarts. The backup power interface facilitates the installation of the backup battery 10 to ensure power supply to the device's real-time clock (RTC) during power outages or restarts, ensuring the continuity of device time. The backup battery 10 is connected to the Jetson Orin NX module through this RTC backup battery 10 interface to enable power monitoring and management functions.

[0041] In some embodiments, the roadside device 1 further includes an HDMI display unit (display screen) and an HDMI interface. The display screen provides video display capability via the HDMI interface provided by the Jetson Orin NX module. The roadside system outputs video signals externally via the HDMI interface.

[0042] In some embodiments, the UPHY(x4) bus provided on the control module 6 of the roadside equipment 1 constitutes an M.2Key M interface, which can be expanded by loading an SSD solid-state storage module with an M.2Key M interface to increase the data storage capacity and storage speed of the module.

[0043] The roadside equipment 1 provided in this embodiment is distributed at different locations in the open-pit mine. It utilizes an information acquisition module 4 to collect visibility information from various roads, enabling dust monitoring throughout the mining area. Simultaneously, a positioning module 5 accurately provides the location information of each roadside equipment 1, pinpointing specific locations with poor visibility. This information is then transmitted to a cloud server 2 via a communication module 7. The cloud server 2 controls the corresponding water spraying device 3 to activate dust suppression operations, thus precisely suppressing dust. This not only ensures effective dust suppression but also rationally utilizes water resources and improves visibility to guarantee safety in the mining area. Furthermore, the roadside equipment 1 employs both a camera 411 and a laser dust sensor 42 to detect visibility on the mining roads, improving detection accuracy to a certain extent. Temperature and humidity sensors 9 are installed in various areas of the roadside equipment 1 to monitor the temperature, enabling rapid heat dissipation with a cooling fan. This ensures the roadside equipment 1 operates at normal temperatures, guaranteeing normal system operation and improving the stability of the roadside equipment 1 in conjunction with the water spraying device 3 for efficient and accurate dust suppression.

[0044] Example 2 The embodiments of this utility model also provide an open-pit mine water spraying dust suppression system, see [link to relevant documentation]. Figure 1 and Figure 5 As shown, the open-pit mine dust suppression system includes roadside equipment 1, cloud server 2, and water spraying devices 3 as described in Embodiment 1. In this embodiment, multiple roadside equipment 1 are provided and distributed on one side of the open-pit mine vehicle travel road; multiple water spraying devices 3 are provided and distributed at various locations on the open-pit mine vehicle travel road; wherein, the cloud server 2 connects the roadside equipment 1 and the water spraying devices 3 via wireless communication; the cloud server 2 is used to receive visibility information and location information fed back by the roadside equipment 1, and to send dust suppression signals to the water spraying devices 3 at the locations corresponding to the location information.

[0045] The wireless communication methods include, but are not limited to, WiFi, Bluetooth, ZigBee, or NB-IoT. This system can use a single wireless communication method or a combination of multiple communication methods.

[0046] In this system, the positions of each roadside device 1 correspond to the positions of each sprinkler device 3. The cloud server 2 includes a location recording module and a location comparison module. The location recording module records the location information of each roadside device 1 and the sprinkler device 3. The location comparison module receives feedback signals from the roadside devices 1, determines their location information, and matches the sprinkler devices 3 with their corresponding positions based on the location information of the roadside devices 1. Through the cooperation of the location recording module and the location comparison module, the system can quickly and easily match the location information of the roadside devices 1 with the corresponding sprinkler devices 3 for watering, thereby achieving precise dust suppression.

[0047] Furthermore, the roadside device 1 is equipped with a first identification code for recording information about the roadside device 1, and the sprinkler device 3 is equipped with a second identification code for recording information about the sprinkler device 3; both the information about the roadside device 1 and the information about the sprinkler device 3 include location information. Through the first and second identification codes, the location recording module can directly record the first and second identification codes, thus facilitating the location comparison module to directly match the corresponding location using the first and second identification codes. In this embodiment, after analyzing visibility, the roadside device 1 compares it with a threshold. When the visibility reaches a certain threshold, it sends a sprinkler request to the cloud server. The sprinkler request includes the ID of the roadside device 1, which includes the location information and the number of the roadside device 1. For example, the visibility threshold is set between 3m and 14m; for example, setting the visibility threshold to 6.5m can improve the visibility and safety of the mining truck's travel route.

[0048] Specifically, several roadside devices 1 are installed on the steps at different heights in the open-pit mine, and additional roadside devices 1 are installed at intersections, T-junctions, or Y-junctions where traffic accidents are prone to occur. For example, four roadside devices 1 are installed at intersections, three roadside devices 1 are installed at T-junctions, and three roadside devices 1 are installed at Y-junctions.

[0049] In this embodiment, the water spraying device 3 is a water truck. The number of water trucks can be reasonably configured based on the size of the open-pit mine to facilitate water spraying and dust suppression treatment at different locations in the open-pit mine.

[0050] By deploying roadside equipment 1 at different locations in the open-pit mine, dust monitoring of the entire mining area is achieved. This, combined with water spraying devices 3, enables precise dust suppression, significantly reducing traffic accidents caused by low visibility and improving the safety of the mining area. At the same time, wireless communication ensures effective transmission of information between the cloud server, water trucks, and roadside equipment 1, guaranteeing timely spraying by water trucks when visibility is low, thereby improving visibility and enhancing the safety of the mining area.

However, if other terms can achieve the same purpose, they can be replaced by other expressions.

In practical applications, the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
