Adaptive Positioning Control System of Bridge Inspection Vehicle

Abstract

The invention discloses a self-adaption positioning control system of a bridge detection vehicle. The bridge detection vehicle comprises walking boots and a walking trolley, wherein the walking boots are devices which are used for detecting close contact and fixation between the detection trolley and a bridge; the walking boots comprise a trolley rail, telescopic guide wheels and telescopic fastening hooks; the walking trolley is a driving device of the detection vehicle, and is used for driving the walking boots and the detection vehicle to walk on the upper chord of the bridge; the walking trolley comprises a telescopic main support and walking wheels. The system comprises a walking-boot section changing control module and a walking trolley control module, wherein the walking-boot section changing control module is used for controlling the walking boots to change sections; the walking trolley control module is used for controlling the walking trolley to walk within a target section after the walking boots stop walking and are positioned by the horizontal fastening hooks. Through the adoption of the control system disclosed by the invention, the control with needed accuracy can be guaranteed. The control system has very important and general reference value and very important and general popularizing value for similar engineering machinery and bridge machinery.

Description

technical field [0001] The invention relates to control technology, in particular to an adaptive positioning control system for a bridge inspection vehicle. Background technique [0002] Bridge inspection vehicle is playing an increasingly important role in bridge inspection and road maintenance, and its wide application requirements make the control of bridge inspection vehicle more and more important. Theoretically, the components and matching tolerances of the bridge are quite accurate in design, but in practice, these components will produce certain errors during the factory manufacturing process and field installation, and there will also be errors when installing the fixed locking wedge. error. Assuming that the sum of these errors is a constant, it can be corrected, but with the change of climate, the deformation error of the bridge after loading, the accumulation error of the mechanical clearance of the inspection vehicle during the movement, and the detection error...

AI Technical Summary

Problems solved by technology

Assuming that the sum of these errors is a constant, it can be corrected, but with the change of climate, the deformation error of the bridge after loading, the accumulation error of the mechanical clearance of the inspection vehicle during the movement, and the detection error of the control system itself are unpredictable. of
