A method of marshalling and collaborative operation of unmanned transportation system in mining area based on 5G

Abstract

The invention discloses a 5G-based grouping cooperative operation method of an unmanned transportation system in a mining area. Through the roadside unit set at the meeting position, each vehicle is equipped with a vehicle-mounted unit and a vehicle-based system for obtaining vehicle position, speed and acceleration information. The 5G multi-vehicle collaborative positioning system and the central control platform calculate and judge the time when two vehicles move to the meeting position of the two-lane according to the current speed, and adjust the speed control within the allowable range under the principle of "full traffic and empty parking". , to complete the coordinated grouping and transportation of the uplink and downlink mine cards. Through the technical solution of the present invention, a coordinated marshalling scheme is provided for the geographical one-way unmanned mineral transportation in mining areas. Based on the high-speed and low-latency characteristics of 5G, information such as the location and speed of mining trucks can be received and communicated in a timely manner. At the same time, the transmission and execution of demand control also directly improves the efficiency of unmanned transportation in mining areas.

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
