摘要
Abstract
In order to solve the disadvantages of traditional profile-based roughness measurement meth⁃ods, such as time consuming, strenuosity and high cost, a measurement system was proposed from the perspective of system response, combined with wireless sensors technology. Pavement roughness system was developed by calculating international roughness index using the vibration of vehicles suspension system. Whereby, several high precision triaxial-acceleration sensors were used to collect vehicular vi⁃bration data. To guarantee the stability of data transmission, a short-ranged wireless communication de⁃vice Zigbee was applied. Data labels were proposed to conduct data fusion. A 3G module was utilized to connect the vehicle data and information center. The acceleration power spectral density analysis was conducted to evaluate the international roughness index (IRI), as well as published and stored the results with e-map. The field tests demonstrate the multiple linear relationship between international roughness index and vehicle suspension system vibration. Compared with the data measured by via laser roughness detection devices, the measuring error of this system is basically under 10%, meeting the need of roadmaintenance activities, which is appropriate for wide range pavement roughness measurement.关键词
