[Abstract]:With the rapid development and improvement of the national highway network in China. It is urgent to develop the related technologies in the field of pavement detection. Pavement smoothness and construction depth are the important factors that affect the driving quality and safety of vehicles. It is also an important index of maintenance management in the course of highway construction, so it is a significant task to design an efficient, accurate and easy to operate pavement smoothness and construction depth detection equipment. In this paper, the design and research of vehicle-borne flatness and structural depth detection system are carried out. Through consulting a large number of relevant documents, understand the domestic and foreign pavement smoothness and structural depth detection technology development status. The basic principles of various detection techniques are studied. A vehicle-borne pavement roughness and construction depth detection system based on laser displacement sensor and dual accelerometer is constructed. The main contents are as follows: 1. The development status and development direction of pavement smoothness and structural depth detection at home and abroad are briefly described, and various evaluation indexes of smoothness and structural depth are studied and analyzed. The calculation model and method of international smoothness index (IRI) are studied. According to the national regulations, the international smoothness index (IRI) and the average section depth (MPD) are used as the output indicators of the system. And carried on the concrete research work around these two indexes. 2. The working principle of all kinds of sensors needed by the system is studied and analyzed, and the performance requirements of the system for sensors, data acquisition cards and industrial control computers are determined. Finally, the components that can meet the design requirements are selected. The structure and installation mode of the system are determined. The algorithm of the software part of the system is studied. The secondary integration of acceleration signal and the removal of DC term are mainly analyzed. And the process of filtering acceleration signal and laser displacement signal. 3. Calibration experiments and actual road tests are carried out. The laser displacement sensors, accelerometers, incremental rotary encoders and other sensors are calibrated. The measurement results of the sensor are corrected. The correlation test between the vehicle mounted pavement flatness and the structural depth detection system and the standard detection is carried out. The repeatability test of testing system and the influence test of driving speed on the test results. The experimental results show that the performance of the system designed in this paper is stable and reliable. It can be used as an actual pavement roughness and structural depth detection system for pavement detection.
