System and method for following industrial vehicle

Abstract

The invention discloses a system and a method for following an industrial vehicle. The system comprises a master controller, wherein the master controller is connected with a vehicle control system. The system is characterized by further comprising a UWB base station, a UWB label and a scanning module, wherein the UWB label is used for transmitting a UWB signal; the UWB base station is used for detecting the UWB signal so as to obtain angle and distance information; the scanning module is used for detecting obstacle information in real time; and the master controller is connected with the UWBbase station and the scanning module, and is used for controlling a following action of the vehicle according to the angle and distance information and adjusting the speed of the vehicle according tothe obstacle information. The directional base station is adopted, angles can be identified in a 360-degree omnidirectional mode, the method is simple, and the system is easy to arrange.

Description

Technical field [0001] The invention relates to the field of vehicle following, in particular to a following system and method for industrial vehicles. Background technique [0002] The main application technologies of the existing automatic following solutions are: ultrasonic, infrared technology, Bluetooth technology, 3D camera and laser technology. Ultrasonic technology requires at least 3 to 4 signal receiving modules, which are arranged and installed according to a specific distance and position. The positioning module transmits signals to the receiving module. The calculation system calculates the positioning module according to the difference in the arrival time of the receiving module through a special calculation method. The position to achieve positioning follow. The biggest drawbacks of ultrasonic technology are 1) reflection problems (including angular errors, mirrors, and multiple reflections); 1) noise interference; 3) cross-border problems, which cause large error...

AI Technical Summary

Problems solved by technology

The biggest defect of ultrasonic technology is 1) reflection problem (including angle error, mirror surface and multiple reflections); 1) noise interference; 3) cross-border problems, etc. cause large errors, low accuracy, and short measurement distance

And the usual practice is to improve the accuracy, it is often necessary to adopt multiple modules to work together, and a variety of technical means are used together, resulting in a complex system and special requirements for installation, such as the need for the same plane, installation at equilateral triangle positions, or It is required that the module does not have any metal objects to shield it, etc.

Therefore, it can only be used in simple following tools, such as suitcases, shopping carts in shopping malls and supermarkets, baby carriages, etc.

[0008] 2) The algorithm system is complex, the amount of data is huge, and the requirements for the surrounding environment are high

This method has special requirements for layout, and the algorithm is complex

If it is not done well, it is difficult to achieve high-precision positioning effect
