Automatic guided vehicle scheduling system and method based on global wireless precise positioning

Abstract

The invention provides an automatic guided vehicle scheduling system based on global wireless precise positioning. The system comprises a real-time positioning layer, an application layer man-machine interface, a distributive vehicle control layer and a wireless communication layer; the real-time positioning layer comprises a to-be-positioning mobile tag, a wireless ranging fixed base station, a UDP (user datagram protocol) datagram transmission module and a coordinate calculation module; the application layer man-machine interface comprises a task management and publishing module, a position monitoring and scheduling module and an environmental modeling and electronic map downloading module; the distributive vehicle control layer comprises a distributive route planning module, an electronic map receiving and storing module, a line patrol and route switching module and an environmental perception module; and the wireless communication layer comprises a wireless transceiver host module, a wireless transceiver slave module and a wireless peer-to-peer communication network. According to the system and the method provided by the invention, as the global real-time wireless accurate timing technology is introduced, the positions of all AGVs (automated guided vehicles) in the system are monitored in real time, and are fed back to a centralized main control computer, so that the computer can perform uniform scheduling on all equipment in the system.

Description

technical field [0001] The invention relates to an automatic guided vehicle dispatching system based on global wireless precise positioning and a method thereof, belonging to the field of automatic conveying equipment and distributed control in industrial automation. Background technique [0002] Automatic guided vehicle (AGV) is a kind of automatic material handling equipment, which has the characteristics of high degree of automation and variable running path, and is the key equipment for realizing automatic handling in advanced manufacturing systems and logistics systems. The automatic guided vehicle system (AGVs) is composed of multiple AGVs and scheduling control software. It is a handling system that can operate independently. It is responsible for material handling in production logistics. It can change the path according to the handling task, improve the flexibility of production and reduce the cost. cost. It is widely used in material handling places such as automo...
