Problems solved by technology

For example, by measuring the distance between the AGV and a fixed object, the disadvantage is that if the fixed object is too far away, a large error will occur, and if the fixed object is too close, it will affect the AGV's operating accuracy, and the measured accuracy is not normal operation; and For example, by using a pen to draw a line, that is, when the AGV stops, use a pen to draw a line along the edge of the AGV to judge. The disadvantage is that manual repeated operations will cause work fatigue. Errors are prone to occur during the manual drawing process, and only before and after measurements can be made. Left and right error, cannot measure offset error

[0065] see Figure 8 , Figure 8 It is a schematic flowchart of the AGV offset measurement method provided by the second embodiment of the present invention.

[0066] The AGV offset measurement method can be applied to the AGV offset measurement device 10 in the first embodiment, and the AGV offset measurement method includes:

[0067] S101: Control the AGV trolley 900 to move on the motion platform 15 according to preset motion data.

[0068] It should be noted that when the AGV trolley 900 is on the moving platform 15 , the irradiation point of the positioning laser 17 on the AGV trolley 900 can stop on or pass through the collection piece 19 arranged on the movement platform 15 .

[0069] S102: When the irradiation point stops on the collection part 19 or passes through the collection part 19, control the positioning laser 17 to irradiate the collection part 19, and leave actual movement data on the collection part 19.

[0070] S103: Obtain offset accuracy data according...

Abstract

The invention discloses an AGV offset measurement method and an AGV offset measurement device, relating to the technical field of AGV positioning. The AGV offset measurement method comprises steps of:controlling an AGV vehicle to move on a motion platform according to preset motion data, wherein a collection piece is arranged on the motion platform, and an irradiation point of a positioning laseron the AGV vehicle stops on the collection piece on the motion platform or passes the collection piece; when the irradiation point stops on the collection piece or passes the collection piece, controlling the positioning laser to irradiate the collection piece, and leaving actual motion data on the collection piece; and obtaining accurate offset data according to actual motion data or differencebetween the actual motion data and preset motion data. The AGV offset measurement method and the AGV offset measurement device reduce workload of measurement of AGV vehicle offset accuracy by a measurement worker, and cause small measurement error.

Description

technical field [0001] The invention relates to the technical field of AGV positioning, in particular to an AGV offset measurement method and an AGV offset measurement device. Background technique [0002] The main function of autonomous navigation AGV (Automated Guided Vehicle, automatic guided vehicle) is to realize the automation of the whole process of loading, unloading and handling of goods and materials. It is widely used in warehousing and manufacturing industries. [0003] AGV must be produced and sold in strict accordance with the requirements of the national standard, but in the process of production and quality inspection, we lack accurate data to identify whether the AGV meets the national standard. The accuracy data of AGV is usually obtained in an indirect and rough way. For example, by measuring the distance between the AGV and a fixed object, the disadvantage is that if the fixed object is too far away, a large error will occur, and if the fixed object is t...
