[0036] Embodiment 1

[0037] In practical applications, the multi-level anti-collision system for the rubber-tyred trackless vehicle for mining of the present invention can be customized and developed according to the specific needs and working environment of the mine. By installing UWB vehicle positioning warning, radar ranging intelligent braking and collision contact intelligent braking devices, vehicle positioning, collision prediction and intelligent braking can be achieved, and potential collision situations can be avoided. By uploading vehicle location and surrounding detection data, comprehensive monitoring and management of the rubber-tyred trackless vehicle for mining can be achieved. At the same time, it can also help managers to find problems in time and take corresponding measures to ensure the safety of rubber-tyred vehicles in underground operations.

[0038] like Figure 1-2 As shown, in this embodiment, a multi-stage anti-collision system for a mining trackless rubber-tyred vehicle is provided, comprising:

[0039] UWB vehicle positioning and warning system 4, used for real-time monitoring of the position of the mining trackless rubber-tyred vehicle by ultra-wideband wireless communication technology, and calculating the travel distance between the rubber-tyred vehicles, and triggering warning measures when the travel distance reaches a first preset distance;

[0040] The radar ranging intelligent braking system 8 is used to measure the approach distance between the rubber-tyred vehicle and nearby objects in real time, and trigger intelligent braking measures when the approach distance reaches a second preset distance.

[0041] The collision contact intelligent braking system is used to monitor the force of obstacles on the rubber layer pad in real time, and trigger emergency braking when the obstacle contacts the rubber layer pad, wherein the rubber layer pad 6 is installed on the top of the mining trackless rubber-tyred vehicle.

[0042] Furthermore, the UWB vehicle positioning warning system 4 is mainly composed of a positioning tag 41, a positioning base station 42, and a positioning platform 43. It calculates the distance between vehicles by real-time positioning of underground vehicles. Once the distance between vehicles exceeds the set safety distance, the warning light 44 is immediately triggered to warn the driver.

[0043] Specifically, the positioning tag 41 is a mark placed on the vehicle, and the positioning system can identify the position of the positioning tag. The positioning system receives signals based on an underground base station and transmits the signals to the positioning platform 43, thereby realizing vehicle positioning.

[0044] Specifically, as the core of the entire system, the positioning platform 43 receives and processes data from the positioning base station, summarizes the underground vehicle location data, and issues warnings to drivers for potential collision threats. The positioning platform 43 displays the vehicle's location information through an interface, and provides functions such as intelligent scheduling and fault warning to provide decision support for managers.

[0045] Furthermore, the radar ranging intelligent braking system 8 is used to measure the distance between the rubber-wheeled vehicle and nearby objects in real time. When the obstacle is close, or once the distance of the nearby object exceeds the safe distance, the intelligent braking measures are immediately triggered to achieve braking and deceleration of the rubber-wheeled vehicle to prevent collision.

[0046] Specifically, the radar ranging intelligent braking system 8 is specifically located on the anti-collision beam 3 , and the anti-collision beam 3 is connected to the outer side of the cab 1 of the trackless rubber-tyred vehicle through the energy absorption box 2 .

[0047] The radar ranging intelligent braking system 8 includes: ranging radar 5, controller 81, permanent magnet 84, electromagnetic coil 85, power supply 82, etc. The ranging radar 5 is used to measure the approach distance between the rubber-wheeled vehicle and nearby objects in real time through radar; the controller 81 receives radar feedback data, and after data processing, connects the power supply 82 to make the electromagnetic coil 85 generate magnetism. After the electromagnetic coil 85 generates magnetism, it attracts the permanent magnet 84 on the brake pedal 83, driving the brake pedal 83 to move, thereby realizing the braking function.

[0048] Furthermore, the collision contact intelligent braking system is mainly composed of a rubber layer pad 6, a flexible membrane sensor 7, a controller 81, and a braking system. The rubber layer pad 6 is used to receive the impact force on the outside of the mining trackless rubber-tyred vehicle and obtain a pressure signal; the flexible membrane sensor 7 is used to transmit the pressure signal to the controller 81; and the controller 81 is used to receive the pressure signal and trigger emergency braking to avoid an impending collision.

[0049] Specifically, when the obstacle contacts the rubber pad 6, emergency braking is used to prevent collision. The flexible membrane sensor 7 is embedded in the rubber pad, which can detect the impact force on the outside of the rubber pad in real time while being protective.

[0050] It should be noted that, in this embodiment, the controller 81 can receive both feedback data from the radar and pressure signals.

[0051] In this embodiment, the multi-level collision avoidance system can effectively prevent the occurrence of collision accidents of rubber-wheeled mining vehicles through collision warning and intelligent braking, thereby improving the safety level of mining operations.

[0052] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
