Pavement smoothness detection method based on mobile terminal and intelligent pavement information real-time monitoring system

Abstract

The invention relates to a pavement smoothness detection method based on a mobile terminal and an intelligent pavement information real-time monitoring system. The method comprises the following steps: collecting vibration information as well as running state information of a driving vehicle through a smart phone and uploading to a central database of the intelligent pavement information real-time monitoring system; analyzing through a data processing server to obtain a cumulative displacement index of a tested pavement based on an acceleration signal, and establishing an international smoothness index prediction model through statistical regression analysis on tested pavement damping information, tested pavement environmental information and the cumulative displacement index of the tested pavement; collecting and calculating the cumulative displacement index of the detected pavement through the steps, and thus obtaining an international smoothness index of the detected pavement depending on the obtained international smoothness index prediction model, the detected pavement damping information, the detected pavement environmental information and the cumulative displacement index of the detected pavement. Through the detection method disclosed by the invention, pavement smoothness detection cost is greatly reduced and a detection cycle is shortened to the greatest extent.

Description

technical field [0001] The invention relates to the detection of road surface smoothness information, in particular to a mobile terminal-based road surface smoothness detection method and an intelligent real-time monitoring system for road surface information. Background technique [0002] Since the "Eleventh Five-Year Plan", the scale of my country's highway construction has made a qualitative leap. By the end of 2012, the total mileage of highways in my country had reached 4.24 million kilometers, and the mileage of expressways had reached 96,000 kilometers. Along with my country's entry into the period of large-scale construction of expressways, the era of large-scale expressway maintenance has followed. It is of great practical significance to establish a "highway maintenance management system" and accelerate the construction of highway management informatization. [0003] As the core part of the highway maintenance management system, the detection and evaluation of pa...

Problems solved by technology

The accuracy, efficiency and intelligence of the manual method are low, and it is difficult to build a networking system; while the operation of professional testing vehicle equipment, the maintenance cost is high, and the dependence on professional technicians is high, so it cannot be promoted on a large scale

Existing detection technologies are limited by human, material and financial resources to varying degrees. The complexity of detection instruments and the difficulty of data processing further prolong the detection cycle of traditional detection methods, making it impossible to conduct comprehensive road surface information on the road network. real-time monitoring
