Vehicle-mounted bridgehead bumping detection and analysis system and method

Abstract

The invention discloses a vehicle-mounted bridgehead bumping detection and analysis system and method. The method is used for detecting and analyzing the bumping condition of a bridgehead, and comprises the steps that S1, after an industrial personal computer installed in a detection vehicle starts a collection mode, pile number information of a photoelectric encoder installed on the rear wheel ofthe detection vehicle is initialized, and the photoelectric encoder, a line scanning camera installed on the rear portion of the roof of the detection vehicle, an inertial navigation system installedon an industrial personal computer and a GPS system installed on the roof of the detection vehicle are driven respectively. According to the vehicle-mounted bridgehead bumping detection and analysissystem and method, bridgehead bumping detection can be efficiently and automatically achieved, the bridgehead bumping calculation model is further established according to the longitudinal section profile curve generated according to the detection data, and the bridgehead bumping severity degree of the bridge can be quantitatively described.

Description

technical field [0001] The invention belongs to the technical field of vehicle jump detection at bridge head, and in particular relates to a vehicle-mounted bridge head vehicle jump detection and analysis system and a vehicle-mounted bridge head vehicle jump detection and analysis method. Background technique [0002] Roads and bridges built on soft soil foundations in the Jiangnan area often undergo uneven settlement after they are opened to traffic, resulting in bridge head jumping, affecting driving ride comfort and ride comfort, and even endangering driving safety in severe cases. By detecting, judging and analyzing the vehicle jumping at the bridge head, it can provide the basic premise and basis for guiding the treatment and maintenance construction of the vehicle jumping at the bridge head, improving the condition of the vehicle jumping at the bridge head, and improving the level of bridge maintenance management. [0003] The existing bridge head vehicle jumping detec...

AI Technical Summary

Problems solved by technology

[0005] (1) Since the plan involves the investigation of the slope of the bridgehead lane, the inspection of the height difference of the bridgehead, the inspection of the bridge expansion joint, and the inspection of the bridgehead board, etc., the detection and inspection process mostly relies on the on-site measurement of professionals, and it is impossible to realize the automatic detection and analysis of the jumping point , the detection and identification of car jumping diseases is inefficient, time-consuming and laborious

[0006] (2) This method is to manually check the vehicle jumping disease at the bridge head, and the inspectors need to conduct on-site measurements on the spot, which will easily affect and interfere with the vehicles passing through the road section, and the vehicles passing quickly will threaten the personal safety of the inspectors. Safety

In the detection of road sections with large traffic volume, road closures are required, which will seriously affect the traffic of this road section

[0007] (3) There are few sampling points in the existing technical scheme, and the judgment of the car jumping point at the bridge head is relatively rough, and the severity of the car jumping at the bridge head cannot be quantitatively analyzed, and it cannot guide the maintenance and construction of the car jumping at the bridge head
