Cloud control system and method for loading and unloading process of automatic-driving mine truck

Abstract

The invention relates to a cloud control system and method for loading and unloading process of an automatic driving mine truck. The cloud control system comprises a cloud control platform, an automatic driving mine truck and a cloud control device; the cloud control platform comprises a server; vehicle data and a digital map are stored in the server. The digital map is continuously revised, vehicle control management is carried out through calculation according to the vehicle data and screening by combining the digital map, so that the automatic driving mine truck is parked in a designated loading and unloading area, the position information and the driving state of the automatic driving mine truck are monitored in real time, and once abnormity occurs, the vehicle is immediately and remotely controlled to be parked, and a parking loading and unloading instruction is executed again; and the cloud control device comprises a loading process cloud control device and an unloading process cloud control device. The control method comprises a loading process cloud control method and an unloading process cloud control method. The control system is simple in structure, low in cost and highin reliability. The control method is high in intelligent degree and reliable in work.

Description

technical field [0001] The invention belongs to the technical field of automatic driving control of mining vehicles, and in particular relates to a cloud control system and control method for the loading and unloading process of automatic driving mining vehicles. Background technique [0002] Because the mining vehicle works in a closed working environment, the road conditions are relatively simple, and the driving route changes little, which is conducive to the realization of the automatic driving function. However, the loading area of ​​the mining area will continue to move with the change of the mining surface, and the relative position of the excavator and the mining vehicle loading area is not fixed, making it difficult for the self-driving mining vehicle to find a safe loading parking area. At present, the method of radar or video image recognition is generally used to solve the problem, but the technical difficulty and development cost are high. On the other hand, it ...

AI Technical Summary

Problems solved by technology

However, on the one hand, due to the large difference in material density in the mining area, it is difficult to control the uniform loading, and the center of gravity of the vehicle is often not in the center. With the lifting of the large box, the center of gravity of the vehicle becomes higher, and the vehicle is prone to tipping; on the other hand, the ground in the unloading area is soft and uneven. , or the center of gravity moves backward when unloading, and the ground subsides, which will also cause the vehicle to overturn
