Quick road surface roughness detection system based on vehicle-mounted accelerometer
The invention relates to a quick road surface roughness detection system based on a vehicle-mounted accelerometer. The system comprises a three-axis acceleration sensor, an angular velocity sensor, a Zigbee short-range wireless communication module, a touchable vehicle-mounted terminal, a GPS (global positioning system) and a central computer information processing system, wherein the Zigbee short-range wireless communication module and the three-axis acceleration sensor are integrated to form data acquisition equipment, and the data acquisition equipment is used for acquiring acceleration values produced during riding of a vehicle and performs internal short-range wireless transmission; the GPS, the angular velocity sensor and a 3G remote module are used for recording geographic coordinates of the riding vehicle and turn angle conditions of the riding vehicle and transmit packed files to a server; the touchable vehicle-mounted terminal is used for acquiring acceleration sensor data and matching the acceleration sensor data with GPS data and angular velocity data by using a time sequence to generate initial data; the central computer information processing system is used for directionally receiving data sent by the to-be-detected vehicle and processing the data to acquire an estimated IRI (internal roughness index)/RQI (riding quality index) to be displayed on an electronic map. The system is used for solving problems that traditional detection methods are time-consuming, labor-consuming, low in efficiency, high in price and the like and monitors the road surface roughness in real time.
