Intelligent optical guiding system

Abstract

The invention discloses an optical guiding device and method. The device is composed of a guided device 1, an optical detecting unit 2 and a guiding light source 3; and according to the actual usage situation, an indicating light source or a video display module group can also be added. Therefore, problems of automatic navigation of a storage AGV trolley, walking path navigation of a robot, and navigation of a toy car can be solved. Compared with the conventional RFID wireless navigation, the optical guiding device and method have the following beneficial effects: a magnetic material is laid on the ground and ways like an active laser scanning type navigation way are employed; the guiding light source with the low cost and small size is used for realizing automatic guidance, so that lots of work for designing track lines on the ground is saved; and with the space advantages, the operating track can be changed flexibly based on needs. Compared with other automatic navigation method, the optical guiding device is easy to popularize.

Description

technical field [0001] The invention relates to the field of unmanned moving trolleys and moving path guidance for moving robots, in particular to an automatic guiding system for the running paths of storage and handling robots. Background technique [0002] With the rapid development of society, a large number of goods have been introduced to the market one after another. Whether it is the warehouse management of large companies or the logistics and warehousing of e-commerce platforms, they all face the problem of goods in and out of the warehouse. Handling robots (AGV, Automated Guided Vehicle for short) are widely used in industry, transportation, warehouse management and other fields. The existing handling robots on the market are equipped with automatic guidance devices such as electromagnetic or optical, which can drive along the prescribed guidance path. [0003] At present, there are mainly the following methods for AGV guidance technology, and these methods have mor...

AI Technical Summary

Problems solved by technology

The guidance method is that the image processing algorithm is relatively complicated, and the marking lines laid on the ground are easy to wear and cause misidentification

6) Reflective laser guidance method, in which the laser scanning radar is installed on the trolley to scan the laser reflection plate installed at the precise position around the driving path. Laser beams are used to determine its current location and navigate. This guidance method requires a series of reflectors to be pre-set around the path to be driven, and the cost is relatively high.

[0005] Aiming at the guidance scheme of AGV trolley, patent CN1263625C proposes an optically guided automatic guided vehicle guidance device. This patent combines the above-mentioned methods 4 and 6, and the laser emitting board needs to be erected in advance. Patent CN103019240B proposes to use ultrasonic sensors to sense Measure the distance information around the preset path and pre-store it in the database to provide path correction information for the subsequent trolley travel. Although this method does not set up auxiliary equipment on the predetermined path, it can target objects that suddenly appear in the path, such as people walking, etc. lead to wrong judgment
