Guidance system and method based on guide rail location

Abstract

The invention relates to a guidance system and method based on guide rail location. The guidance system comprises an upper computer, a guide rail belt, beacons and a transmitter / receiver, wherein the upper computer can give out a planned path, a direction and a stop position; the reflectivity of the middle of the guide rail belt and the reflectivity of the two sides of the guide rail belt are different, and optical signals emitted to the guide rail belt can be reflected back to form a projection of the middle of the guide rail belt on the transmitter / receiver; the beacons are arranged on the guide rail belt at certain intervals; the transmitter / receiver can compare the projection with a self-positioning central line to obtain a relative position deviation with the middle of the guide rail belt as reference, the transmitter / receiver can receive information sent by the beacons to obtain a movement request of the upper computer, and the transmitter / receiver can compare an actual passing sequence of the beacons with a set passing sequence to obtain a movement direction deviation; the transmitter / receiver can input the relative position deviation, the movement direction deviation, the stop position, a turning angle, a speed limit, the self direction, speed and inclined angle information into a driving control system of a target to be located and guided, and the purpose that the target to be located and guided moves or stops according to the request of the upper computer is achieved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a guide rail-based positioning and guiding system and method, especially suitable for autonomous navigation equipment with relatively fixed moving paths. Background technique [0002] Existing rail-based positioning guidance methods include electromagnetic track methods, metal track methods, and visual guidance methods. The electromagnetic track method uses the electromagnetic track laid on the ground to set the driving route, and the guided target is guided according to the information of the electromagnetic track detected by the sensor installed on it. The advantage of electromagnetic guidance is that the guide line is concealed, and it is not easy to be polluted and damaged , the guidance principle is simple and reliable, convenient for communication and control, no interference to sound and light, low manufacturing cost, the disadvantage is that the path is difficult to chang...
