Embodiment Construction

[0048] In the era of big data, map navigation software has become a must-have travel software for people. According to reports, the number of users of AutoNavi Maps and Baidu Maps has exceeded 1 billion. Most smartphones are embedded with sensors such as GPS, acceleration, and gyroscope, which can collect various types of data on human activities and the surrounding environment, and implicitly include important information such as basic attributes of road roughness, providing a data source for automatic detection of road roughness. This system should be integrated into the existing navigation map software, so that it can constitute a large number of data collection sources, form an "Internet +" service that conforms to the concept of crowdsourcing, meet the needs of road operation and detection, and improve road smoothness detection Efficiency and test data reliability.

Abstract

The invention discloses a road smoothness detection system based on intelligent mobile phone crowdsourcing collection, comprises a data acquisition module arranged in a smart phone, A data sending module and a cloud management center, The data acquisition module establishes a crowdsourcing task when the user opens the electronic map navigation software. The crowdsourcing task comprises acquiring the current longitudinal acceleration value and the road inclination angle through the built-in sensor of the mobile phone, and acquiring the position, the heading, the time and the moving speed of theroad segment where the user is currently located. The data sending module sends the crowd-sourcing task to the cloud management center through the network. The cloud management center receives crowdsourcing tasks from different users, classifies and integrates all kinds of data in the crowdsourcing tasks, and then analyzes and integrates the data through a road smoothness detection algorithm to evaluate the road quality. The invention improves the detection efficiency of the road smoothness and the reliability of the detection data, and meets the requirements of the highway side operation andthe side detection.

Description

technical field [0001] The invention relates to the technical field of traffic information engineering and control, in particular to a road smoothness detection system based on smart phone crowdsourcing collection. Background technique [0002] At this stage, the comfort, safety and economy of travel have been widely concerned. The research on road driving quality shows that the smoothness characteristics of the road directly affect the driving quality of the road surface. From the perspective of driving, the uneven road surface will increase the driving resistance, which will cause additional vibration of the vehicle and cause driving bumps, which will affect the speed and safety of driving, and will easily cause fatigue of passengers or damage to goods; The road surface exerts a corresponding reaction force, and rainwater will accumulate on the uneven road surface, which will accelerate the damage of the road surface and affect the service life and maintenance cycle of the...
