Embodiment Construction

[0023] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the invention.

[0024] like figure 1 As shown, the upper computer 100 gives the initial direction, initial speed, and distance on the planned path of the transmitter and receiver in the stopped state by comparing the beacon 102 identification number and the destination beacon identification number of the information currently received by the transmitter and receiver 103. Beacon identification number list; during the moving process of the transmitter and receiver, update the movement requirements of the transmitter and receiver in real time through the communication 107 with the beacon and the communicati...

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...
