Technical Field
[0001] The utility model relates to the technical field of anti-collision warning for mining trucks, and more specifically to an anti-collision warning device for trucks used in open-pit mines. Background Art
[0002] In a mining environment, there is a lot of dust, many curves, and a long braking distance for mining trucks, making anti-collision warning for mining trucks a problem. Although there are few idle people in the working environment of mining trucks, in actual driving, there will be certain safety accidents and collisions with other vehicles due to the large number of blind spots. Moreover, the environment of mining trucks is generally dusty, and the driver's field of vision will be greatly affected.
[0003] At present, in response to the above problems, in the existing technology, the ultrasonic sensor in the ultrasonic technology is easily covered by dust in the dusty mining environment, resulting in low ranging accuracy; the infrared technology has a short detection distance and does not have the ability to detect curves; bad weather and dust in the mining environment will have a great impact on the measurement; and GPS positioning has high cost and poor stability, which is not conducive to large-scale production and commissioning.
[0004] Due to the special environment of mines, high requirements are placed on the real-time detection. Low detection accuracy and low real-time detection will lead to safety accidents.
[0005] Therefore, how to provide a truck anti-collision warning device for open-pit mines with high real-time performance and accurate detection is a problem that technical personnel in this field urgently need to solve. Utility Model Content
