Hub-type robot and detecting method for system for autonomously detecting road surfaces

Abstract

The invention discloses a hub-type robot system for autonomously detecting road surfaces. The hub-type robot system comprises a robot body and a remote-monitoring auxiliary system, wherein information is transmitted between the robot body and the remote-monitoring auxiliary system by a wireless communication mode; the robot body is provided with a control system, a non-destructive detection system and an operation mechanism; the operation mechanism is arranged on the robot body; the non-destructive detection system is connected with the operation mechanism; the control mechanism is electrically connected with the operation mechanism and the non-destructive detection system; the non-destructive detection system comprises a resistivity instrument; the operation mechanism comprises a telescopic mechanism; the resistivity instrument is connected with the telescopic mechanism; an independently driven steering device is arranged at the bottom part of the robot body. The invention also discloses a road-surface detecting method. By adoption of the hub-type robot system disclosed by the invention, intelligent detection can be realized; due to no need of manual driving, the detection safety and the accuracy of data detection are improved; multiple non-destructive detection sensors are integrated into one, comprehensive evaluation on the road surfaces and the internal conditions can be realized, the detection efficiency is greatly improved, and the influence on the road trafficability is also reduced.

Description

technical field [0001] The invention relates to a pavement detection device and method, in particular to a hub-type pavement autonomous detection robot system and detection method. Background technique [0002] After the expressway is completed, in order to ensure the safety and efficiency of traffic, it needs regular maintenance. With the rapid increase in the mileage of expressways in China and the increase in the service life of the roads, expressways have entered a period of equal emphasis on construction and maintenance. Expressways with more than 50,000 kilometers have generally entered the normal maintenance period after the defect liability period, and the overall personnel scale of the maintenance industry has grown rapidly. With the "Twelfth Five-Year Road Maintenance and Management Development Outline" of the Ministry of Communications, the proportion of major and medium repairs has been increased from 13% to 17%, and the proportion has increased by nearly 30%.

Problems solved by technology

At present, the detection and evaluation of road surface conditions mainly rely on manual visual inspection, which mainly depends on experience, and the detection accuracy is poor

The alternative is to use manual instrument detection, which is better than visual data accuracy, but there are also the following problems: First, manual data collection is easily affected by manual operation errors, data accuracy cannot be guaranteed, and personal safety No guarantee; second, the rate of manual inspection is low, requiring a lot of manpower, labor-intensive and inefficient, and the inspection time is long, which affects the traffic efficiency; third, manual inspection can only be a single instrument, and only one defect can be detected at a time , it is not possible to make a comprehensive assessment of the pavement condition

However, the disadvantage of this type of inspection vehicle is that it still needs manual control and manual judgment, and cannot meet the requirements of certain inspection processes for motion control (such as stopping at a certain distance), and cannot independently detect and fuse data for automatic evaluation. And it can only detect the condition of the road surface, not the condition below the road surface
