5G-based mining area unmanned transportation system marshalling cooperative operation method

Abstract

The invention discloses a 5G-based mining area unmanned transportation system marshalling cooperative operation method which comprises the steps: setting a roadside unit at a meeting position, installing a vehicle-mounted unit and a 5G-based multi-vehicle cooperative positioning system for obtaining the position, speed and acceleration information of vehicles on each vehicle, and a central controlplatform; judging the time when two vehicles move to the meeting position of the two lanes according to the current vehicle speed by calculating, and controlling and adjusting the vehicle speed within an allowable range under the large principle of full-running and empty-parking to complete cooperative marshalling transportation of upper and lower mine trucks. According to the technical scheme, acollaborative marshalling scheme is provided for geologic one-way driverless mineral transportation of a mining area, and based on the characteristics of high speed and low time delay of 5G, information such as the position and the speed of a mining truck can be received and calculated immediately in time; and meanwhile, the unmanned transportation efficiency of the mining area is directly improved by sending and executing demand control.

Description

technical field [0001] The invention belongs to the technical field of unmanned driving in mining areas, and in particular relates to a grouping and collaborative operation method in a 5G unmanned transportation system in mining areas. Background technique [0002] my country has a vast territory and is rich in mineral resources. There are 159 kinds of minerals with proven reserves and more than 100,000 mines. The mining and transportation of mines have attracted much attention due to issues such as environment, safety, and efficiency. In order to solve production pain points such as frequent safety accidents in mining areas, difficulty in recruiting drivers, and high management and operating costs, with the construction of smart mines and the rapid development of unmanned driving technology, unmanned driving in mining areas has emerged as the times require. [0003] Unmanned vehicles in mining areas mainly refer to unmanned mining trucks. As a sub-module of smart mining ar...

Problems solved by technology

[0004] In recent years, some experts and scholars have proposed a method for self-driving vehicles to meet cars on narrow roads, but the existing technology is mainly aimed at some temporary narrow roads caused by man-made urban and rural roads, and has the following shortcomings: narrow roads refer to the On narrow roads, oncoming vehicles, cyclists on the road, parking partially parked in the lane or parking in the second row and other temporary short-distance roads are narrow, and it is not suitable for geographically long distances with only a few designated wrong-way vehicles One-way slope road section; this method uses on-board sensors to detect the speed and acceleration data of oncoming vehicles and oncoming vehicles. For long-distance one-way road sections, the sensor cannot detect incoming vehicles, so it is impossible to obtain data and perform meeting processing
