Embodiment 1

[0019] Such as figure 1 Shown is a schematic diagram of the overall flow of a road quality dynamic monitoring method based on sanitation vehicles, including the following steps:

[0020] 1. Establish the road model of the target road and initialize it. The road model includes at least the detection route, the GPS position information of the preset detection points on the detection route, the laser positioning reference value of each detection point, and the road quality status value of each detection point.

[0021] The method of initializing the road model is as follows: manually set the detection route and the position of the detection point, use the lidar positioning data of the first detection of each detection point on the target road as the model's lidar positioning reference value, and use the detection result as each detection point. The initial value of the road quality state at the point location. In actual operation, you can preliminarily set the detection route t...

Embodiment 2

[0033] This embodiment provides a road quality dynamic monitoring device based on a sanitation vehicle that can apply the method described in Embodiment 1.

[0034] Such as figure 2As shown, it is a schematic diagram of the overall structure of a road quality dynamic monitoring device based on a sanitation vehicle in this embodiment mounted on the rear of the sanitation vehicle, specifically including a GPS module 1 mounted on the sanitation vehicle for obtaining the meter-level position of the sanitation vehicle Information; laser radar 2, used to obtain centimeter-level position information of the sanitation vehicle; ground penetrating radar 3, used to detect road quality; detection position compensation device 4, used to adjust and compensate for the sanitation vehicle swaying left and right during travel. The left-right deviation of the ground-penetrating radar detection position; the controller 5 is electrically connected with the GPS module 1, the laser radar 2, the gro...

Abstract

A dynamic monitoring method for the road quality based on a sanitation vehicle comprises the following steps: establishing a road model for a target road, and initializing the road model; performing road quality detection on the target road by using a road quality dynamic monitoring device mounted on the sanitation vehicle; and comparing and analyzing data change according to the detection resultto deduce road quality change information. The device is mounted on the sanitation vehicle, and the characteristics of nighttime operation and periodic operation of the sanitation vehicle are fully utilized, so the restriction of the traffic environment to detection development and the adverse influences of the detection development on the traffic are overcome, and the labor cost is saved; the periodic continuous automatic monitoring of the road is achieved, the shortcoming of long working cycle of traditional inspection work is overcome, the quality status of the road is reflected through thecontinuous change of the internal structure of the road, and the problems of low working efficiency and difficult data analysis brought by traditional artificial analysis and parsing of detection data are solved; and a set of an automatic detection point compensation method and a compensation device is improved to improve the radar detecting and positioning accuracy, so the accuracy and the usability of the detection data are improved.

Description

technical field [0001] The invention belongs to the technical field of road state detection, and relates to a road quality dynamic monitoring method based on a sanitation vehicle. Background technique [0002] At present, the methods for detecting the state of municipal roads and bridge pavement mainly include road coring detection methods and non-destructive testing methods such as ground penetrating radar, ultrasonic, image, and surface wave detection. The road coring detection method will cause irreversible damage to the road surface. The non-destructive testing method belongs to the sampling test of the road structure. It usually uses artificial point detection or vehicle-mounted equipment for detection. On the one hand, the construction operation is complicated, the detection cost is high, the efficiency is low, and the impact on traffic is relatively large. More, the interference caused is greater, which affects the detection effect; on the other hand, due to the comp...
