基于Bluetooth传输的自行式路面平整度测量系统的设计

Automatic Road Roughness Measuring System for Self-propelled Car Based on Bluetooth

路面平整度是评价公路,特别是高速公路技术性能最重要的指标之一。如何对其进行快速精确的测量是当前十分重要的课题。文章设计了一套自行式路面平整度测量系统,采用全球首例整合性6轴运动处理组件MPU6050测量车体的倾斜角度,实现了路面平整度的自动获取;Bluetooth传输模块用于智能终端和车体之间进行数据的传送,实现了智能小车的远程控制以及对平整度信号的接收。研究结果表明,采用非接触式检测方法的自行式路面平整度测量系统由于其高速率、长距离、精度高等特点,必将成为路面平整度检测技术的发展方向。

The road roughness is one of the most important indexes of performance for appraising highways especially speedways.As a result,how to measure it fleetly and accurately has become a quite significant issue.A self-propelled car was designed to measure road＇s roughness.The world＇s first integrated 6-axis Motion Tracking device MPU6050 was used to collect data of road＇s roughness automatically.The Bluetooth module was adopted to realize the communication between a small car and a smart terminal,thus controlling the car wirelessly and returning the data of road＇s roughness back to smart terminal.The results indicate that automatic road roughness measuring system,having the advantages of being non-contact,high-speed,long distance and precise,has become the trend for road roughness detecting technology.
