Embodiment Construction

[0022] In order to further explain the technical method and efficacy adopted by the present invention to achieve the predetermined purpose, the specific implementation and efficacy of a new AGV visual navigation control method of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, it is a composition block diagram of a novel AGVS visual navigation control method of the present invention. The visual navigation method controls the forward and backward of the AGV trolley by identifying the marking line of the road and taking its deviation and direction information as the input of the control module. It includes: a road identification module for road marking line identification, a host computer video monitoring module, a positioning module for AGV car positioning using RFID, a motion control module for controlling the operation of the car, and a path planning module.

Abstract

The invention provides a novel AGV visual navigation control method. The method includes a road identification module is used to identify marker lines such as crossroads and bends so as to obtain parameters, which includes position deviation and direction deviation, between an AGV body and a route guide line; a motion control module to perform fuzzy control on the position deviation and direction deviation so as to control the motions of an AGV; a wireless positioning module is used to obtain the current position information of the AGC and display the current position information; a video monitoring module is used to monitor AGV surrounding environments and the information of the AGV; a route planning module is used to plan the shortest route between the AGV and a target. The novel AGV visual navigation control method has the advantages that real-time communication with background is achieved, functions such as visual navigation of multiple branch roads, video monitoring, route planning and wireless positioning are achieved, and high cost performance and adaptability are achieved.

Description

1. Technical field [0001] The invention relates to a new type of AGV (Automatic Guided Vehicle) control method. Aiming at the problems of single AGV navigation mode, low flexibility and high cost in the current market, a vision-based AGV navigation control method is designed. 2. Background technology [0002] For modern automated production, it is indispensable to realize the automatic handling of spare parts and raw materials. Compared with the traditional manual way of transporting goods, a new type of logistics handling method, that is, AGV unmanned handling navigation vehicle, can basically realize the handling, loading and unloading of goods without manual operation. Relevant planning, command and other operations can be carried out. [0003] However, the AGV products currently on the market all use magnetic guidance, electromagnetic guidance or laser guidance. These guidance methods have the problem of low flexibility. For example, the guidance method of magnetic guid...
