Problems solved by technology

[0003] Most of the existing speed measurement structures use encoders to directly test the wheel speed. However, when the wheel is deformed under load, wear gradually increases and slips, the data obtained by the encoder directly connected to the wheel cannot reflect the actual movement of the AGV car, and When the wheels cross pits or raised obstacles, the rotation of the wheels is difficult to reflect the overall motion of the AGV car, which makes it difficult to reflect the actual speed and travel distance of the AGV car by the encoder test data directly connected to the wheel.
In addition, in actual engineering, it is often necessary to automate the transformation of the tractor of the purchased finished product, and it is difficult to directly install the encoder on the original tractor itself, so the transformation is difficult

Abstract

The invention discloses an AGV test structure, a walk test method and a trolley, and relates to the technical field of AGV testing. The test structure comprises a test controller and a test mechanism.The test mechanism comprises an installation main body, a test wheel, a first displacement sensor and a second displacement sensor. The test wheel is slidably connected to the installation main body,can slide up and down relative to the installation main body, and can rotate around the axis of the test wheel; the first displacement sensor is in transmission connection with the test wheel, and isused for testing the rotation data of the test wheel; the second displacement sensor is used for testing sliding data of the test wheel sliding up and down relative to the installation main body, andthe test controller is electrically connected with the first displacement sensor and the second displacement sensor and can calculate the moving speed or the moving stroke of the AGV according to therotation data and the sliding data. According to the AGV test structure, the walk test method and the trolley, the test data can more truly reflect the motion condition of the AGV.

Description

technical field [0001] The invention relates to the technical field of AGV testing, in particular to an AGV testing structure, a walking testing method and a trolley. Background technique [0002] Autonomous navigation AGV (Automated Guided Vehicle, automatic guided transport vehicle) is more and more used in the warehousing industry. At present, AGV already has a variety of navigation methods. Among them, the odometer used for speed measurement or distance measurement is an important module in various navigation methods. [0003] Most of the existing speed measurement structures use encoders to directly test the wheel speed. However, when the wheel is deformed under load, wear gradually increases and slips, the data obtained by the encoder directly connected to the wheel cannot reflect the actual movement of the AGV car, and When the wheels have crossed pits or raised obstacles, the rotation of the wheels is difficult to reflect the overall movement of the AGV car, which ...
