Calibration device and method for loading position of mining area driverless system

Abstract

The disclosure provides a calibration device for loading position of a mining area driverless system . The calibration device is characterized by comprising loading equipment for bearing a vehicle-mounted computer system, a vehicle-mounted positioning system and a vehicle-mounted wireless communication system and for calibrating a loading position. The vehicle-mounted positioning system is used for acquiring position coordinates and attitude directions of the loading equipment; the vehicle-mounted wireless communication system is used for realizing communication between the vehicle-mounted computer system and external equipment; and the vehicle-mounted computer system comprises a data acquisition unit, a data release unit and an information data transmission control unit, and is used for calculating the loading position according to the position coordinates and the attitude direction. According to the invention, the loading position is rapidly calibrated in the modes of attitude position model fitting, topographic data matching, loading position model calculation and the like, the tedious sensor calibration process of other bucket positioning modes is reduced, the loading positioncalibration difficulty is greatly reduced, and the calibration precision and speed are improved.

Description

technical field [0001] The present disclosure relates to the field of unmanned driving, and in particular to a calibration device and method for a loading position of an unmanned driving system in a mining area. Background technique [0002] Among the five main links of perforation-blasting-excavation-transportation-waste discharge in open-pit mining operations, the current technology is relatively mature, and it is the mining and transportation link that is easiest to realize unmanned operations in a short time. Among them, the excavation link can realize remote control of excavation equipment, reducing the number of on-site operators; and in the transportation link, unmanned mining vehicles will gradually enter the mine site to start experimental operations. [0003] For the unmanned driving of open-pit mining vehicles, among the three links of loading-transportation-discharging, the transportation and disposal links can be realized independently by relying on the control ...

AI Technical Summary

Problems solved by technology

Due to the large terrain changes in the loading area, the loading position will change each time. The loading equipment needs to quickly and efficiently calibrate the loading position and send it to the unmanned mining vehicle, so that the unmanned mining vehicle can accurately stop at the loading position and reduce the secondary position adjustment. The problem of reduced loading efficiency brought about by
