Vehicle AGV system based on cyber-physical system and traffic control method

Abstract

The present invention provides a vehicle AGV system based on cyber-physical system and a traffic control method. The system comprises an AGV vehicle, an intersection controller, a master controller and a workshop positioning system. A vehicle following method based on a safe distance, a vehicle overtaking method of an emergency task and a collision prediction and processing method are employed bya corresponding traffic control method. A processor is added into the design of a vehicle, the calculation ability of the vehicle is improved, the vehicle can independently decide an operating state according to sensed information, the real-time information sharing of the vehicle is realized through a communicator module, and the efficiency of information collection and utilization is improved. Through the traffic control method, the transport efficiency of the vehicle can be improved, the transport time is shortened, the collision of vehicles is avoided through an adjustment in advance without stopping, and the time and energy are saved while the safety is improved.

Description

technical field [0001] The invention discloses an AGV vehicle design and traffic control method based on a cyber-physical system (Cyber-Physical System, CPS), belonging to the technical field of logistics. Background technique [0002] The extensive use of automatic guided vehicles (AGVs) is an important basis for realizing automated manufacturing and intelligent logistics, and AGVs play an important role in the automation of manufacturing systems and large-scale logistics storage systems, container terminals, and external (underground) transportation systems. For example, using a large number of AGVs to improve the efficiency of Amazon and Alibaba warehouse and logistics operations. Giving AGV self-decision ability and interaction ability is the first step to realize intelligent logistics. It is of great significance to improve the efficiency and safety of AGVs during transportation. [0003] In recent years, the research and design of AGV collision avoidance methods main...

Problems solved by technology

[0005] The above research and inventions have greatly promoted the safe transportation of the AGV in the workshop, but in the existing design, the AGV lacks sufficient data processing capabilities and communication capabilities, and there are mainly the following problems in the transportation process: (1) The limited workshop space limits the number of AGVs used. If the distance between two vehicles is shortened, more vehicles can be used in the same space, and the utilization rate of road space needs to be improved; (2) Vehicle driving flexibility is low, Cannot overtake and handle emergency tasks through overtaking; (3) In the design o...
