Self-driving forklift system

Abstract

The invention relates to a self-driving forklift system. The self-driving forklift system comprises a forklift body, a forklift on-board control system, a forklift navigation positioning system, a forklift safety obstacle avoidance system, a forklift upper management system, a forklift walking path planning system, a forklift task scheduling management system, a forklift traffic management system, a display system, a control signal seamless intelligent link system, a forklift body communication system, a forklift upper communication system, and an intelligent warehouse management control system server. According to the self-driving forklift system, unmanned motion control over a forklift can be achieved, the problem that the forklift is poor in adaptability to the working environment is solved, the system deployment is simple, the adaptability to light and ground flatness of the working environment of the self-driving forklift is high, the later maintenance workload is small, and 24-hour operation in a dark environment can be achieved.

Description

technical field [0001] The invention belongs to the technical field of forklifts, in particular to an automatic driving forklift system. Background technique [0002] The existing automatic driving forklift system has the following technical defects: [0003] 1) Using laser radar, two-dimensional code, geomagnetism, vision and other methods of navigation has poor adaptability to the working environment. [0004] 2) The cost of laser navigation is high. [0005] 3) Lidar navigation needs reflectors and strict surveying and mapping, and the deployment is complicated; laser SLAM without reflectors has high requirements on the flatness of the ground for self-driving forklifts; the use of QR codes and geomagnetism requires laying QR codes and geomagnetism on the ground. The self-driving forklift will cause damage to the QR code and geomagnetism, and the QR code and geomagnetism must be maintained frequently; the use of visual navigation requires high uniformity of light and ill...

AI Technical Summary

Problems solved by technology

[0003] 1) Using laser radar, two-dimensional code, geomagnetism, vision and other methods for navigation, poor adaptability to the working environment

[0004] 2) High cost of laser navigation

[0005] 3) Lidar navigation needs reflectors and strict surveying and mapping, and the deployment is complicated; laser SLAM without reflectors has high requirements on the flatness of the ground for self-driving forklifts; the use of QR codes and geomagnetism requires laying QR codes and geomagnetism on the ground. The self-driving forklift will cause damage to the two-dimensional code and the geomagnetism, and the two-dimensional code and the geomagnetism must be maintained frequently; the use of visual navigation has high requirements on the uniformity and illumination of the working environment

[0006] 4) The automatic driving forklift is limited by the characteristics of the navigation method, and the driving speed of the automatic driving forklift is limited

[0007] 5) Most autonomous forklift routes are not flexible enough

[0008] 6) The warehouse layout cannot be dynamically adjusted in real time

[0010] 8) The navigation method of the self-driving forklift is not very suitable for indoor and outdoor walking, especially for outdoor navigation and positioning in extreme weather

[0011] 9) The self-driving forklift lacks effective three-dimensional obstacle avoidance measures, especially when advancing along the direction of the forklift fork to pick up the goods, there are potential safety hazards

[0012] 10) It is difficult to interface between the old and new production systems, especially when the old production system cannot open the interface.

[0013] 11) The management between production and the automatic driving forklift control system is basically in a loose coupling state, and the intelligence level of the whole process is not high
