Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a mining intelligent traffic light control system based on radar sensors. Background Technology

[0002] Underground mines are confined spaces with poor lighting, numerous bends, junctions, and inclines, as well as various obstacles such as machinery and pipelines. Furthermore, underground environments may contain hazardous factors such as gas and dust. Traffic accidents underground can easily trigger secondary disasters, further escalating the severity of the initial incident. Therefore, to reduce accidents and ensure miner safety, effective measures must be taken to manage underground traffic, making the application of traffic lights an essential choice.

[0003] To address these issues, this application presents a radar sensor-based intelligent traffic light control system for mining applications. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this utility model provides a mine intelligent traffic light control system based on radar sensors.

[0005] A radar sensor-based intelligent traffic light control system for mines, including an intrinsically safe display screen for mines, is characterized by:

[0006] The intrinsically safe display screen for mining is installed as a traffic light at the turning point of the underground traffic intersection. A stop line is drawn on the ground near the intrinsically safe display screen on the road. On one side of the stop line, an intrinsically safe radar sensor, an intrinsically safe camera, and an intrinsically safe alarm are installed in sequence.

[0007] Furthermore, in order to better realize this utility model, the intrinsically safe radar sensor for mining includes two radar sensors, namely a first radar and a second radar.

[0008] Furthermore, in order to better realize this utility model, for T-junctions, three intrinsically safe mining display screens are installed at the intersection, and a first radar, a second radar, an intrinsically safe mining camera, and an intrinsically safe mining alarm are installed on each of the three branch roads.

[0009] Furthermore, in order to better realize this utility model, for the U-shaped bend, two intrinsically safe mining display screens are installed at the bend, and each intrinsically safe mining display screen is equipped with a first radar, a second radar, an intrinsically safe mining camera and an intrinsically safe mining alarm on one side.

[0010] Furthermore, in order to better realize this utility model, for the intersection, four intrinsically safe mining display screens are installed at the intersection, and a first radar, a second radar, an intrinsically safe mining camera and an intrinsically safe mining alarm are installed on each of the four branch roads.

[0011] Furthermore, in order to better realize this utility model, the intelligent traffic light control system for mines also includes an intrinsically safe controller for mines that controls and connects all electrical components, and an explosion-proof and intrinsically safe power supply box for mines.

[0012] The beneficial effects of this utility model are:

[0013] This utility model can solve traffic problems at various intersections such as T-junctions, U-shaped bends, and crossroads in mines. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Figures 1-2 This is the first specific embodiment of the present invention. This embodiment is a mine intelligent traffic light control system based on radar sensors. The intrinsically safe display screen 5 is installed as a traffic light at the turning intersection of the underground traffic road. A stop line 6 is drawn on the ground near the intrinsically safe display screen 5. On one side of the stop line 6, an intrinsically safe radar sensor, an intrinsically safe camera 3, and an intrinsically safe alarm 4 are arranged in sequence. The intrinsically safe radar sensor includes two radar sensors, namely a first radar 1 and a second radar 2.

[0026] For T-junctions, three intrinsically safe mining display screens 5 are installed at the intersection, and a first radar 1, a second radar 2, an intrinsically safe mining camera 3, and an intrinsically safe mining alarm 4 are installed on each of the three branch roads.

[0027] For the U-shaped bend, two intrinsically safe mining display screens 5 are installed at the bend. Each intrinsically safe mining display screen 5 is equipped with a first radar 1, a second radar 2, an intrinsically safe mining camera 3, and an intrinsically safe mining alarm 4 on one side.

[0028] For intersections, four intrinsically safe mining display screens 5 are installed at the junction, and a first radar 1, a second radar 2, an intrinsically safe mining camera 3, and an intrinsically safe mining alarm 4 are installed on each of the four branch roads.

[0029] The intelligent traffic light control system for mines also includes an intrinsically safe controller for controlling all electrical components and an explosion-proof and intrinsically safe power supply box for mines.

[0030] At a T-junction, the traffic lights at each intersection initially turn green. When a vehicle enters from intersection A, the radar at intersection A detects the vehicle's entry, and the traffic light at intersection A turns green (trigger mechanism: when a vehicle triggers the first radar zone, the light at intersection A turns green, and the traffic lights at intersections B and C turn red. If the first and second radar zones are not triggered within 5 seconds (time adjustable), the traffic lights at intersections B and C return to green. After triggering the second radar zone, the lights remain unchanged). The audible and visual alarms at intersections B and C will sound an alarm, alerting passing vehicles and pedestrians to "vehicles are approaching, be careful," and simultaneously, the traffic lights at intersections B and C will change from green to red. When the radar at intersections B and C detects the vehicle again (the vehicle passes through the second radar zone in sequence, then the first radar zone), indicating that the vehicle has exited, the audible and visual alarms at intersections B and C will stop sounding, and the red lights at intersections B and C will sequentially turn green (transition time adjustable), returning to the initial state. (The same principle applies to other intersections.)

[0031] Figures 3-4 In the second specific embodiment of this utility model, at a U-shaped bend, the traffic lights at each intersection are initially green. When a vehicle enters from intersection A, the radar at intersection A detects the vehicle's entry, and the traffic light at intersection A turns green (triggering mechanism: when a vehicle triggers the first radar zone, the light at intersection A turns green, and the traffic light at intersection B turns red. If the first and second radar zones are not triggered within 5 seconds (time adjustable), the traffic light at intersection B returns to green; after triggering the second radar zone, the light stops changing). The audible and visual alarm at intersection B will sound an alarm, reminding passing vehicles or pedestrians to "be careful as a vehicle is approaching," and simultaneously, the traffic light at intersection B changes from green to red. When the radar at intersection B detects the vehicle again (the vehicle passes through the second radar zone and then the first radar zone in sequence), it indicates that the vehicle has exited, the audible and visual alarm at intersection B stops sounding, and the red light at intersection B turns green (transition time adjustable), returning to the initial state. (The same applies to other intersections.)

[0032] Figures 5-6In the third specific embodiment of this utility model, at a crossroads, the traffic lights at each intersection are initially green. When a vehicle enters from intersection A, the radar at intersection A detects the vehicle's entry, and the traffic light at intersection A turns green (triggering mechanism: when a vehicle triggers the first radar zone, the traffic lights at intersections B, C, and D turn red; if the first and second radar zones are not triggered within 5 seconds (time can be set), the traffic lights at intersections B, C, and D return to green; after triggering the second radar zone, the lights do not change). The audible and visual alarms at intersections B, C, and D will sound an alarm, reminding passing vehicles or pedestrians that "a vehicle is approaching, be careful," and simultaneously, the traffic lights at intersections B, C, and D will change from green to red. If the radar at intersections B, C, or D detects a vehicle again (the vehicle passes through the second radar area in sequence, then the first radar area), confirming that the vehicle has exited, the audible and visual alarms at intersections B, C, and D will stop sounding, and the traffic lights at intersections B, C, and D will sequentially turn green (the transition time can be set), returning to their initial state. (The same applies to other intersections.)

[0033] Figure 7 In the fourth specific embodiment of this utility model, for a T-junction, if a vehicle is detected to be parked for a long time in the no-parking area (the area between the first radar and the second radar), the camera will capture the image, and the system will automatically record the no-parking time and the violation.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
