Description

Technical Field

[0001] The present invention relates to the technical field of material transportation, and in particular to an unmanned transport vehicle for transporting materials under multiple road conditions. Background Art

[0002] Material transportation refers to the spatial displacement of means of production through transportation activities. Material transportation includes two parts: material transportation in the production field and material transportation in the circulation field. Material transportation is one of the main functions of logistics and the central activity of logistics business. Therefore, sometimes people regard material transportation as a synonym for logistics. All logistics activities, and even the movement of all goods, are inseparable from the transportation link. The task of material transportation is to solve the problem of spatial displacement of materials. In other words, the purpose of material transportation is to eliminate the regional differences between production supply and consumer demand, and to deliver various materials to consumers in a timely manner to realize their use value. Material transportation The reason why it plays a vital role in logistics activities is that transportation costs account for the largest proportion of logistics costs, thus becoming a major factor affecting the level of logistics costs. Unmanned guided vehicles refer to transport vehicles equipped with automatic guidance devices such as electromagnetic or optical devices, which can travel along a specified guidance path and have safety protection and various transfer functions. In industrial applications, unmanned guided vehicles do not require a driver and use rechargeable batteries as their power source. Generally, their routes and behaviors can be controlled by computers, or their routes can be established using electromagnetic tracks. The electromagnetic tracks are attached to the floor, and the unmanned guided vehicles move and act according to the information brought by the electromagnetic tracks.
