Embodiment Construction
[0023] In order to clearly illustrate the solutions in the present invention, preferred embodiments are given below and detailed descriptions are given in conjunction with the accompanying drawings.
[0024] The rutting detection scheme of the present invention cancels the acceleration displacement detection device or the gyro fixed attitude detection device, and installs 13-25 laser distance measuring devices on the beam steel body of the measuring vehicle. The number of installations can be set arbitrarily, and the laser distance measuring devices The beam steel body that cannot be perpendicular to the vehicle body needs to form a certain angle α with the steel body of the beam, so as to facilitate the subsequent calculation of the measured vertical distance. During the driving process of the vehicle, the CPU continuously receives the distance signal from the laser distance measuring device and performs the following calculation steps according to the predetermined distance i...

The invention discloses a road rut detection method. In the method, 13 to 25 laser ranging devices are arranged on a cross beam steel body of a measurement vehicle. The method comprises: the laser ranging devices detect the distance to a road according to a preset distance and time interval; a processor works out the corresponding vertical distance from the ground to the cross beam steel body of the measurement vehicle according to the received distance signals which are acquired by the laser ranging devices and the included angle between the processor and the cross beam of the vehicle body; the deformation track curve of a road rut can be acquired according to the obtained vertical distances of the laser ranging devices; the road rut depth can be obtained by using the deformation track curve of the road rut; and road rut data on all sections can be detected quickly by the method. The method of the invention thus is described in detail. In the invention, the measurement process is simple and accurate, devices such as an accelerometer and a gyroscope are not mounted, the rut detection cost is reduced, the detection speed and the accuracy and reliability of the detection result are improved, and the speed of road maintenance is improved.
Description
technical field [0001] The invention relates to the technical field of road maintenance, in particular to a road surface rutting detection method. Background technique [0002] Pavement rutting data is one of the important bases for evaluating the technical status of expressways and first-class highways, analyzing pavement maintenance needs, and optimizing the allocation of maintenance funds. Accurate detection of road rutting has extremely important practical significance for road maintenance and management. [0003] With the wide application of laser technology, for the rapid and accurate detection of road rutting, road research institutions in the United Kingdom, the United States, Denmark, Sweden and other countries have done a lot of technical research and equipment development, and developed a series of road rutting rapid detection methods. Detection methods, devices and related standards, including road rutting detection devices based on laser technology. [0004] T...
