Problems solved by technology

[0005] This common way of transporting goods requires frequent unloading of goods, that is, loading scattered goods onto a large unmanned transport vehicle and unloading the goods from the large unmanned transport vehicle to distribute the goods, wasting a lot of manpower, Material resources, time, and easy to damage the goods in the process of unloading, waste of time and easy to cause deterioration of goods such as fruits and vegetables, in short, this more common unmanned freight transportation method is not efficient
Although there is also a method of transporting goods using integrated blocks, that is, multiple pieces of goods are packed together like containers and transported in a modular manner, but this method still requires continuous unloading.
[0006] In view of the fact that unmanned driving technology has not yet been fully popularized, unmanned driving technology has not been widely used in logistics, and it is still limited to a small range of use or test phase. At present, most of the goods are delivered manually. Drive a freight vehicle and deliver the goods to the target site through people such as couriers

Abstract

The invention relates to the technical field of logistics distribution, in particularly to freight transport system based on unmanned child-mother vehicles and a freight transport method thereof. Thegoods vehicle comprises a driverless bus, a self-driving sub-vehicle and a control system for controlling the parent vehicle and the sub-vehicle, a set of deck lifting motors and a deck mounted on thelifting motors are arranged in the carriage of the bus car, the rear part of the bus car is provided with a lifting type car door. The shipping method comprises a preparation process, a boarding process, a transport process, a discharging process, a distribution process and a returning process. The invention has the advantages that no freight driver, porter and freight distribution worker is needed, the problem of freight handling is solved, the handling damage of the goods is reduced, the safety factor and logistics efficiency of the freight are greatly improved, and the deterioration problem of the food goods to be distributed is reduced.

Description

technical field [0001] The invention relates to the technical field of logistics distribution, in particular to a freight system and a freight method based on unmanned child and mother vehicles. Background technique [0002] Today, with the rapid development of the logistics industry, the traditional freight transportation method is far from meeting the needs of the times. It must be combined with intelligent technology to make it gradually intelligent and modern, and greatly improve the efficiency of cargo transportation and distribution. . [0003] With the increasingly intelligent development of society, the driverless technology of automobiles has gradually developed and matured, and is gradually applied to all aspects of society. Unmanned driving technology is undoubtedly the most critical technology to realize the intelligentization of freight transportation. The key to unmanned freight transportation is to use unmanned vehicles to realize the cargo transportation pro...
