[0002] Open-pit mining refers to a mining method in which mineral resources are located on or near the surface of the earth. It is a common mining method, especially for some large-scale deposits. Open-pit mining typically uses large machinery and blasting techniques to remove the rock and soil covering the minerals, and then the minerals themselves are mined.

[0003] After mining, mineral resources are transported by heavy trucks. Heavy trucks are characterized by their large size, heavy weight, and high inertia. As heavy trucks travel continuously, the road conditions in open-pit mines also change, such as becoming bumpy. Heavy vehicles traveling at high speeds on bumpy road sections experience bumps and jolting.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Figure 1 This is a modular schematic diagram of an open-pit mine vehicle anti-collision system according to an embodiment of the present utility model. Figure 2This is an installation diagram of an open-pit mine vehicle anti-collision system according to an embodiment of the present utility model, as shown below. Figure 1 , Figure 2 As shown, the open-pit mine vehicle collision avoidance system includes: a vehicle end 200 and a road end 100 connected by communication; the road end 100 is set on the target road and includes multiple undulating road segment marking devices 110 set at the beginning of each undulating road segment on the target road; wherein, the undulating road segment marking device 110 sends undulating road segment marking signals to the vehicle end 200 within the detection range of the vehicle end 200; the vehicle end 200 is set on the target vehicle and includes an undulating road segment detection device 210, a control module 220, and an alarm device 230; the undulating road segment detection device 210 is communicatively connected to the undulating road segment marking device 110 within the detection range and is used to receive the undulating road segment marking signals sent by the undulating road segment marking device 110; after receiving the undulating road segment marking signals, the control module 220 sends an alarm signal to the alarm device 230 to trigger the alarm device 230.

[0023] Roads in open-pit mines differ from ordinary roads. After mining, mineral resources are transported via heavy trucks. These trucks are large, heavy, and have significant inertia. Therefore, the repeated driving, braking, and skidding of these trucks cause potholes due to differences in road material and density. These potholes also exhibit an irregular, random distribution over time. Heavy vehicles experience bumps when traveling at relatively high speeds over potholes, and if drivers are not aware of these uneven surfaces, collisions or accidents may occur. Therefore, it is necessary to remind drivers of road conditions, particularly those involving potholes.

[0024] In related technologies, one approach to road condition alerts involves using GPS to determine the vehicle's location and comparing it with a road map containing information on pothole locations. The alert is then issued based on the comparison result. However, the accuracy of this approach is heavily influenced by the communication environment between the positioning base station and the positioning terminal. When there is obstruction between the base station and the terminal, the positioning information becomes inaccurate. Furthermore, open-pit mines, due to their mining and filling processes, typically create uneven and complex terrain. Therefore, using GPS to determine the vehicle's location and subsequently the road condition is also relatively inaccurate when GPS is not accurate, resulting in less accurate road condition alerts based on pothole locations.

[0025] Based on this, in this embodiment, the road end 100 of the open-pit mine vehicle collision avoidance system is set on the target road, including multiple undulating road segment marking devices 110 set at the beginning of each undulating road segment on the target road; wherein, the undulating road segment marking device 110 sends undulating road segment marking signals to the vehicle end 200 within the detection range of the vehicle end 200; and the vehicle end 200 is set on the target vehicle, including an undulating road segment detection device 210, a control module 220, and an alarm device 230; the undulating road segment detection device 210 is communicatively connected to the undulating road segment marking device 110 within the detection range, and is used to receive the undulating road segment marking signals sent by the undulating road segment marking device 110; after receiving the undulating road segment marking signals, the control module 220 sends an alarm signal to the alarm device 230 to trigger the alarm device 230.

[0026] The above-mentioned communication method between the undulating road section detection device 210 and the undulating road section marking device 110 is not affected by the aforementioned environmental factors. Even when the GPS accuracy is not high, it can still clearly remind the vehicle of the potholes in front of it, so that the driver can know in advance that he will pass through the potholes ahead through the alarm device 230 and control the vehicle accordingly based on the road conditions.

[0027] In one embodiment, the road condition of the target road can be measured manually in advance to obtain the measurement results of potholes in the target road. Then, based on the measurement results of potholes, an undulating road segment marking device 110 is installed at the beginning of each undulating road segment on the target road.

[0028] In one embodiment, the alarm device 230 may include at least one of a buzzer, an indicator light, and a display screen.

[0029] In one embodiment, an image acquisition device can be used to acquire images of the target road in advance, and then the acquired images can be identified by machine learning to obtain the measurement results of potholes in the target road. Furthermore, based on the measurement results of potholes, an undulating road segment marking device 110 is installed at the beginning of each undulating road segment on the target road.

[0030] In one embodiment, the road condition of the target road can be manually measured and updated according to a preset update cycle, or images of the target road can be acquired using an image acquisition device. Machine learning can then be used to identify potholes and uneven road sections in the target road for road condition updates. The preset update cycle can be 15 days, 30 days, 60 days, etc.

[0031] The above-mentioned solution of this application adopts the implementation method of undulating road section detection device 210 and undulating road section marking device 110. The collection of road condition information is not affected by environmental factors. Even when the GPS accuracy is not high, the road condition information of the road where the vehicle is located can still be clearly determined, so that the driver can adaptively control the vehicle by reading the road condition displayed by the display module.

[0032] As an exemplary embodiment, the vehicle terminal 200 further includes a gyroscope; the gyroscope is communicatively connected to the control module 220 and is used to send a vibration identification signal to the control module 220 when the vibration amplitude of the target vehicle is greater than a preset amplitude; after receiving the vibration identification signal, the control module 220 sends an alarm signal to the alarm device 230 to trigger the alarm device 230 to sound an alarm.

[0033] To avoid the problem of failing to provide early warnings to drivers due to changes in road conditions caused by repeated heavy vehicle traffic and the lack of timely road condition marking devices 110, the vehicle terminal 200 in this embodiment also includes a gyroscope. The gyroscope is communicatively connected to the control module 220 and is used to send a vibration marking signal to the control module 220 when the vibration amplitude of the target vehicle exceeds a preset amplitude. After receiving the vibration marking signal, the control module 220 sends an alarm signal to the alarm device 230 to trigger the alarm device 230.

[0034] In one embodiment, communication between the undulating road segment marking device 110 and the undulating road segment detection device 210 can be achieved through radio frequency identification (RFID) technology. Specifically, the undulating road segment marking device 110 can be an RFID tag, and the undulating road segment detection device 210 includes a first RFID reader. The first RFID reader receives the undulating road segment marking signal sent by the undulating road segment marking device 110 within the detection range by reading the information stored in the RFID tag.

[0035] As an exemplary embodiment, the undulating road section marking device 110 can be a readable and writable RFID tag; the RFID reader can receive the undulating road section marking signal sent by the undulating road section marking device 110 by reading the information stored in the readable and writable RFID tag.

[0036] In one embodiment, communication between the undulating road segment marking device 110 and the undulating road segment detection device 210 can be achieved through Bluetooth technology. As an exemplary embodiment, the undulating road segment marking device 110 is a first Bluetooth transceiver, and the undulating road segment detection device 210 is a second Bluetooth transceiver. The second Bluetooth transceiver can receive the undulating road segment marking signal sent by the undulating road segment marking device 110 by reading the information stored in the first Bluetooth transceiver.

[0037] When the undulating road segment marking device 110 communicates with the undulating road segment detection device 210 using Bluetooth and radio frequency technologies, limitations such as signal strength and environmental factors in radio frequency and Bluetooth communication may lead to a situation where the control module 220 has not yet triggered the alarm device 230 when the target vehicle has arrived at the undulating road segment. To solve this problem, as an exemplary embodiment, the road end 100 also includes multiple infrared vehicle detection devices installed at the beginning of each undulating road segment. The infrared vehicle detection devices are communicatively connected to the control module 220. When the target vehicle passes through the detection range of the infrared vehicle detection device, it sends the vehicle detection signal to the vehicle end 200. After receiving the vehicle detection signal, the control module 220 sends an alarm signal to the alarm device 230 to trigger the alarm device 230.

[0038] In one embodiment, the infrared vehicle detection device can communicate with the control module 220 via a separately configured communication module.

[0039] To avoid the problem of inaccurate GPS positioning, RTK is used to determine the vehicle position in this embodiment. As an exemplary embodiment, the open-pit mine vehicle collision avoidance system also includes at least one RTK base station, and the vehicle end 200 includes a first RTK end, which is communicatively connected to the RTK base station.

[0040] In this embodiment, the first RTK terminal can determine the location of the target vehicle in real time through communication with the RTK base station.

[0041] As an exemplary embodiment, the vehicle end 200 further includes a first camera device; the first camera device is installed in the driver's cab and the camera direction is towards the driver.

[0042] In this embodiment, the first camera device is installed in the driver's cab, with the camera facing the driver; the first camera device is used to capture a first video containing the driver's face.

[0043] In one implementation, after acquiring the first video, the vehicle terminal 200 uploads the first video to an offline server; the offline server processes and identifies the first video to obtain vehicle information, driver information, and driver behavior information, and stores the vehicle information, driver information, and driver behavior information in the offline server.

[0044] To detect whether the driver is wearing a seatbelt, as an exemplary embodiment, the vehicle end 200 also includes a seatbelt buckle detection device; the seatbelt buckle detection device is disposed in the seatbelt buckle of the target vehicle, and sends a seatbelt alarm indicator signal to the control module 220 when the seatbelt is not locked; after receiving the seatbelt alarm indicator signal, the control module 220 sends an alarm signal to the alarm device 230 to trigger the alarm device 230.

[0045] In this embodiment, the seat belt buckle detection device is installed inside the seat belt buckle of the target vehicle. The seat belt buckle detection device may be provided with a trigger end and a detection end. When the seat belt is not locked, the trigger end sends a seat belt alarm indicator signal to the control module 220. After receiving the seat belt alarm indicator signal, the control module 220 sends an alarm signal to the alarm device 230.

[0046] As an exemplary embodiment, in order to acquire the road conditions of the target road, the road end 100 includes a plurality of second camera devices, which are installed on both sides of the target road at preset intervals, with the camera direction facing the target road.

[0047] In this embodiment, the second camera device is installed on both sides of the target road at preset intervals, with the camera direction facing the target road, so as to collect a second video containing the road surface conditions.

[0048] In one implementation, after the second camera device acquires the second video, the road end 100 uploads the first video to the offline server; the offline server processes the second video to obtain road segment information and road condition information, and stores the road segment information and road condition information in the offline server.

[0049] As an exemplary embodiment, in order to update the information stored in the undulating road segment marking device 110 set at the road end 100, the road end 100 further includes a second RFID reader or a third Bluetooth transceiver.

[0050] In this embodiment, the second RFID reader or the third Bluetooth transceiver can communicate with the undulating road segment marking device 110 to modify the undulating road segment marking signal stored in the undulating road segment marking device 110.
