Bridge rapid detection vehicle based on multi-sensor unmanned driving

Abstract

The invention discloses a bridge rapid detection vehicle based on multi-sensor unmanned driving. The bridge rapid detection vehicle comprises a vehicle body, a travel path detection device, a bridge detection device, a wireless network transmission device and a central controller, wherein the travel path detection device senses the surrounding environment of a travel path of a vehicle body, the central controller judges whether the vehicle body deviates from the travel path or encounters an obstacle or not, the central controller sends a control signal to a vehicle body driving part to adjustthe vehicle body travel path, the bridge detection device detects a bridge state according to the travel path state, the bridge state is sent to a management terminal through a wireless network transmission device, the management terminal observes detection data uploaded by a detection vehicle in real time, the management terminal sends a control instruction to the vehicle body through the wireless network transmission device to adjust the travel path and the travel state of the vehicle, so remote control detection is realized. The bridge rapid detection vehicle is advantaged in that a bridgecan be automatically detected, a manager can complete real-time detection of the bridge through remote operation, detection precision is high, detection is convenient, detection efficiency is improved, and manpower and material resources are saved.

Description

technical field [0001] The invention belongs to the technical field of bridge detection, in particular to a bridge rapid detection vehicle based on multi-sensor unmanned driving. Background technique [0002] In recent years, my country's transportation construction has developed rapidly, and large-scale bridges have been completed one after another. However, various damages will inevitably occur during long-term use, resulting in resistance attenuation and potential safety hazards. The health inspection of the bridge is related to the safety of transportation and the safety of people's lives and property; in order to ensure the safe operation of the bridge, the bridge structure must be inspected, and various damages on the surface and interior of the bridge can be checked and diagnosed early and accurately. [0003] The current commonly used detection methods are manual detection or bridge detection equipment, which have certain limitations. Manual detection has problems s...

Problems solved by technology

When using bridge testing instruments for testing, most of the single-point testing data obtained from multi-period observations is used to evaluate the safety performance of the bridge after analyzing the displacement changes of the monitoring points. The result is quite different from the actual state

And there are many conditions in the inspection now, it is necessary to choose a time period with less traffic flow or stop the operation of the bridge, which brings inconvenience to people's life and travel, and through manual cooperation with large-scale machines to carry out step-by-step inspections, the lower surface of the bridge and the lower surface of the inspection bridge High bridges are very inconvenient, not only inefficient, a waste of manpower and material resources, but also bring safety hazards to people
