Description

Technical Field

[0001] This application relates to the field of mining equipment technology, and in particular to a mining monitoring device. Background Technology

[0002] With the advancement of industrial automation, various automated equipment has entered various production sites, especially in the mining industry. By using automated equipment, the number of personnel entering the mining area can be reduced, thereby improving the safety of workers in the mining area.

[0003] In the mining industry, the most commonly used automated equipment is the driverless mining truck. Furthermore, these trucks are equipped with obstacle avoidance devices to prevent collisions and improve driving safety. Currently, the main obstacle avoidance devices installed on driverless mining trucks are radar, which detects obstacles in the truck's path and allows it to effectively avoid them.

[0004] Furthermore, in order to monitor the real-time driving status of the unmanned mining truck, the radar installed on the mining truck can be connected to the host computer to send the monitoring data of the radar in the drone to the host computer in real time. This allows the operators on the host computer to know the driving status of the unmanned mining truck in real time, so that they can take corresponding measures in time in case of accidents.

[0005] Currently, there is a limitation in transmitting data collected by the radar to the host computer: the host computer must be selected based on the radar's communication interface, which makes the selection of the host computer inconvenient. Summary of the Invention

Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0023] Figure 2This is a logical schematic diagram of another mining monitoring device provided in an embodiment of this application. Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This application provides a mining monitoring device, see [link to relevant documentation]. Figure 1 The system includes: a lidar and a host computer; the lidar is communicatively connected to the host computer.

[0027] The lidar includes a data acquisition module, a first controller, a memory, and a communication module;

[0028] The data acquisition module is communicatively connected to the first controller, the first controller is connected to each communication interface of the communication module, and each communication interface of the communication module is connected to the communication interface of the host computer.

[0029] The memory is communicatively connected to the first controller;

[0030] The communication module includes a 485 serial port, a CAN interface, and an Ethernet interface; the communication interface of the host computer includes at least one of the 485 serial port, CAN interface, and Ethernet interface.

[0031] As can be seen from the above, the host computer can communicate with the lidar through the communication interface. Since the lidar supports three interface protocols: 485 serial port, CAN interface and Ethernet interface, the multiple interfaces ensure that different types of host computers in the mining area can connect to the internal communication interface of the lidar, thereby exchanging data with the lidar.

[0032] Furthermore, the Ethernet interface protocols include Modbus-RTU, Modbus-TCP, and RTMP, supporting multiple application layer protocols, thereby ensuring good device compatibility and meeting actual data transmission needs.

[0033] Furthermore, the host computer is typically an industrial computer, but it can also be various desktop computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, and smart in-vehicle systems. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted devices.

[0034] Furthermore, in this application, the data acquisition module of the lidar is communicatively connected to the first controller, enabling the data acquisition module to send the acquired data to the first controller, thereby enabling the first controller to send the data to the host computer through the communication module; in addition, the first controller can perform data analysis, thereby enabling the lidar itself to have certain capabilities for on-site situation analysis, fault diagnosis, and hazard assessment.

[0035] Of course, the lidar mentioned in this application can be installed not only on unmanned mining vehicles, but also on other equipment requiring obstacle avoidance. For example, lidar can scan the interior of a mine to obtain a three-dimensional data model of the mine interior, as well as information such as gas concentration, temperature, and pressure, thereby achieving real-time monitoring of the mine interior. Furthermore, lidar can also identify rock fissures, support deformation, and other conditions within the mine, promptly detecting potential safety hazards and providing a safer and more reliable working environment for the mining industry. Related details can be found in existing technologies and will not be elaborated upon here.

[0036] In summary, the mining monitoring equipment provided in this application includes a lidar unit and a host computer. The lidar unit has three interfaces: a 485 serial port, a CAN interface, and an Ethernet interface. These multiple interfaces allow for selection of any one of these interfaces when choosing a host computer. In contrast, existing technologies typically only offer one type of interface, making host computer selection inconvenient. Therefore, compared to existing technologies, the mining monitoring equipment provided in this application significantly improves the ease of host computer selection.

[0037] Furthermore, assuming the mining area is equipped with different types of host computers, when the lidar is equipped with three interfaces—a 485 serial port, a CAN interface, and an Ethernet interface—it can be ensured that different types of host computers in the mining area can connect to the communication interface of the lidar's internal communication module. This allows the lidar to send the data collected by the data acquisition module to the host computer, enabling the host computer to analyze and judge the situation in the mining area in a timely manner based on the received data, thereby improving on-site safety.

[0038] Optionally, the communication module may have multiple 485 serial ports, multiple CAN interfaces, and multiple Ethernet interfaces.

[0039] When multiple interfaces are set up, not only can other interfaces be used directly when there are problems with other interfaces, but multiple host computers can also be connected at the same time, improving the convenience of use.

[0040] Optionally, in another exemplary embodiment of this application, the first controller is generally selected as a microcontroller unit (MCU) to reduce the size of the radar and improve its integration.

[0041] The micro-controller is the central data processing unit of the LiDAR. It utilizes STMicroelectronics' STM32F103RCT6 micro-controller, which has been developed to support multiple interfaces including RS-485 serial port, CAN interface, and Ethernet port. It can upload data or communicate with other manufacturers' controllers, such as EPEC, via various application layer protocols including TCP / IP, Modbus-TCP, and Modbus-RTU. On one hand, it performs preliminary processing of the data collected by the data acquisition system and presets logic based on existing processing modes to make preliminary judgments on potential hazards or fault states on-site, such as alarms for unauthorized personnel approaching dangerous areas or road obstructions. On the other hand, this component uploads data to the host computer as needed for further data processing and monitoring.

[0042] Optionally, see Figure 2 The data acquisition module includes a laser, a beam controller, and a photodetector. The laser generates laser light, the beam controller controls the angle of the laser beam, and the photodetector receives the laser light reflected back from obstacles.

[0043] The data acquisition module is primarily responsible for providing real-time, reliable laser parameters to the micro-first controller. Furthermore, these laser parameters include those of the emitted laser, such as its angle, and those of the reflected laser, such as the time it takes to receive the reflected laser.

[0044] For other related information on lasers, beam controllers, and photodetectors, please refer to the relevant existing technologies; they will not be detailed here.

[0045] Optionally, the laser is a solid-state laser. Solid-state lasers have higher beam quality and longer wavelengths, making them better suited to the harsh and complex environment of mines.

[0046] The development of solid-state lidar has made lidar smaller, lighter, and significantly reduced in cost, while improving reliability and stability.

[0047] Optionally, the beam controller employs a solid-state approach, utilizing optical phased arrays (OPA) technology to enable faster and more precise scanning of object surfaces by the radar. Furthermore, the small size of the OPA allows for further improvements in the integration and miniaturization of the mining lidar.

[0048] Optionally, the photodetector uses a single-photon avalanche diode (SPAD). SPADs offer higher sensitivity and superior real-time response. Furthermore, their bias voltage of 20-30V is compatible with the power supply circuit of this mine-use lidar.

[0049] Alternatively, in another exemplary embodiment of this application, the memory is a pluggable memory card.

[0050] Furthermore, the memory size is greater than or equal to a predetermined value, for example, greater than or equal to 128GB. Furthermore, the data stored in the memory includes three parts: one part is the LiDAR configuration parameters, which can record multiple parameter configuration histories; another part is the historical record of LiDAR fault alarms and on-site public opinion diagnosis information; and the third part is the real-time scanning information of the LiDAR on-site, the recording interval of which can be configured according to real-time needs.

[0051] Optionally, in another exemplary embodiment of this application, the outer surface of the lidar is provided with an explosion-proof housing. This gives the housing good explosion-proof performance, effectively resisting high temperatures, humidity, and flammable and explosive substances in the mining area.

[0052] Alternatively, in another exemplary embodiment of this application, the explosion-proof housing is made of an aluminum alloy material with a strength higher than a predetermined value.

[0053] Furthermore, the protection level is IP68.

[0054] Optionally, in another exemplary embodiment of this application, the explosion-proof housing is fixedly connected to the communication interface, and a sealing gasket is provided at the location where the explosion-proof housing connects to the radar, thereby preventing dust and moisture from entering and ensuring the safe and stable operation of the internal electronic components.

[0055] 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. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
