Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Such as Figure 1-6 shown.

[0031] A kind of AGV operation control method based on passive RFID and auxiliary vision, it comprises the following steps:

[0032] First, install passive RFID electronic tags and graphic image acquisition devices on the AGV; figure 1 As shown, passive RFID electronic tags are best installed at the bottom of the AGV and installed in groups, such as figure 2 as shown, figure 2 Three passive electronic tags are installed in a row;

[0033] Secondly, install an RFID reader on the path that the AGV passes through, so that the RFID reader is connected to the AGV control center through a wired network; figure 1 shown;

[0034] Third, install a graphic display device on the path that the AGV passes to match the installation position of the RFID reader. The graphic display device is connected to the AGV control cente...

Abstract

The invention provides an AGV (Automatic Guided Vehicle) operation control method based on passive RFID (radio frequency identification) and aided visual. The method is characterized in that a control center acquires the position information of an AGV on the basis of a passive RFID technology; the AGV receives a dispatching demand of a cutter distribution center on the basis of an aided visual technology; and the dynamic monitoring of the execution process of distribution tasks of the AGV, distribution plan dispatching and accurate path trace function can be realized through designing numerical workshop RFID reader layout, dispatching patterning commands and an accurate high-efficiency real-time image processing algorithm; and therefore the bidirectional communication between the control center and the AGV can be realized under the condition of not using a radio communication method. By the adoption of the AGV operation control method, the problem that the AGV cannot be controlled remotely in an occasion with high requirement on safety because radio communication cannot be used can be solved, and the dispatching communication is safe and reliable.

Description

technical field [0001] The present invention relates to an AGV control technology, especially AGV wired control technology, specifically an AGV operation control method based on passive RFID and auxiliary vision, which includes quasi-real-time monitoring of the location of the AGV by the control center and AGV Acquisition and recognition of instructions issued by the control center. Background technique [0002] AGV (Automatic Guided Vehicle) refers to an automatic guided vehicle, which is an unmanned automatic handling vehicle powered by a battery and equipped with a navigation system. The salient feature of AGV is unmanned driving. Using the automatic guidance system, the AGV can automatically drive along the predetermined route without manual piloting, and automatically transport the goods from the starting point to the destination. , the production process and other changes can be changed flexibly, and it has the advantages of good flexibility, high degree of automation...
