Intelligent optical guiding system

Abstract

The present invention discloses an optical guiding device and method. The device includes a guided device 1, an optical detection unit 2 and a guiding light source 3. Depending on the actual use situation, an indicating light source or a video display module can also be added. The invention can solve the problems of automatic navigation of storage AGV trolleys, robot walking path navigation, toy car navigation and the like. Compared with conventional RFID wireless navigation, the present invention adopts methods such as laying magnetic materials on the ground, laser active scanning navigation, etc., and adopts low-cost, small-volume guiding light sources to realize automatic guiding functions, eliminating the need to do a lot of work on designing track routes on the ground, fully Taking advantage of the space advantage, the running trajectory can be flexibly changed according to the needs, which is easier to promote vigorously than other automatic navigation methods.

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
