Problems solved by technology

[0004] In the existing pavement information collection process, it is necessary to collect all the information on the pavement, that is, the damaged pavement and the non-damaged pavement, and the amount of pavement information collected is large. The geographical location of the road surface is unknown, and the damaged road surface cannot be promptly and accurately notified to the driving vehicles on the road surface in a timely and effective manner, resulting in traffic accidents such as car accidents when vehicles pass the damaged road surface

Embodiment 1

[0091] The state measurement system during the use of the road surface in this embodiment first measures the type of the road surface, then measures the smoothness of the road surface, and finally detects whether there is damage on the road surface; the system includes:

[0092] inspection vehicle;

[0093] The road surface type measuring unit is used for measuring the type of road surface and outputting the recognition result of the road surface type;

[0094] The road surface flatness measuring unit is used to measure the flatness of the road surface;

[0095] The road surface damage locating unit is used to detect whether the road surface is damaged, and when the road surface is damaged, collect the image information of the damaged road surface, and obtain the position information of the damaged road surface;

[0096] Wherein, the road type determination unit includes a detection data acquisition module, a first preprocessing module of a microprocessor, and a first calcula...

Embodiment 2

[0120] The state measurement system during the use of the pavement in this embodiment, on the basis of Embodiment 1, also includes a detection unit for the invisible disease of the pavement structure layer, and the detection unit for the invisible disease of the pavement structure layer includes a ground-penetrating radar and a ground penetrating radar installed on the detection vehicle. Encourage the road surface sounding device, and the fourth preprocessing module of the microprocessor and the fourth computing module of the cloud server;

[0121] Among them, the excitatory road surface sounding device continuously knocks on the road surface, so that the sound wave generated by the road surface vibration due to the knocking on the road surface propagates downward along the road surface structure layer from the surface layer, and at the same time, the road ground penetrating radar emits electromagnetic waves to the road surface, and the road ground penetrating radar The emissio...

Embodiment 3

[0130] The state measurement system during the use of the road surface in this embodiment, on the basis of Embodiment 2, also includes a heat source affecting the road surface measurement unit, which is used to provide a non-contact heat source for the road surface and monitor the temperature change of the road surface. The temperature change data determines the state of the road surface; it includes a heat source supply device, a temperature monitoring device, a fifth preprocessing module of a microprocessor, and a fifth processing module of a cloud server, wherein the heat source supply device is an active visible light thermal A light source or an infrared laser source; the temperature detection device is an infrared thermopile detector or an uncooled infrared focal plane array detector.

[0131] The heat source supply device is used to provide a non-contact heat source to the road surface to change the temperature of the road surface. The heat source supply device is an act...

Abstract

The invention discloses a system for determining the state in a road surface using process, and aims at solving the multielement and comprehensive determination problem of the road surface state in the using process. The system for determining the state in the road surface using process is used for first determining the type of a road surface, then determining the flatness of the road surface and finally detecting whether the road surface is damaged or not. The system comprises a detection vehicle, a road surface type determination unit, a road surface flatness measurement unit and a road surface damage positioning unit, wherein the pavement type determination unit is used for determining the type of the road surface and an outputting a road surface type recognition result; the road surface flatness measurement unit is used for determining the flatness of the road surface; and the road surface damage positioning unit is used for detecting whether the road surface is damaged or not, acquiring image information of the damaged road surface when the road surface is damaged, and then obtaining position information of the damaged road surface. According to the system disclosed by the invention, the road surface state measurement data is high in accuracy, so that the road surface state can be accurately reflected.

Description

technical field [0001] The invention relates to a state measurement system during the use of road surfaces. Background technique [0002] With the rapid development of the road transportation industry, the maintenance and management of roads are becoming more and more important, among which, the acquisition of road surface damage information becomes very important. [0003] At present, in the collection of road surface state information, the collection of road surface information is usually carried out through the road surface information collection vehicle, wherein the information collection vehicle is equipped with a camera, and the road surface information is stored by way of camera through the driving of the information collection vehicle on the road surface Get up, and after the collection of the whole road section is completed, the stored data will be transmitted to the control center, and the control center will judge the damage of the road surface through artificial ...
