Road surface roughness detection method and intelligent road surface information real-time monitoring system based on mobile terminal

Abstract

The invention relates to a mobile terminal-based road surface smoothness detection method and an intelligent road surface information real-time monitoring system. The method includes: collecting vibration information and driving state information of a driving vehicle through a smart phone and uploading to the central database of the intelligent road surface information real-time monitoring system, The data processing server analyzes and obtains the accumulative displacement index based on the acceleration signal of the test road section, and establishes an international flatness index prediction model by performing statistical regression analysis on the test road section damping information, the test road section environmental information, and the test road section cumulative displacement index. The accumulated displacement index of the detected road section is collected and calculated through the above steps, and the international smoothness index of the detected road section is obtained according to the obtained international roughness index prediction model, the damping information of the detected road section, the environmental information of the detected road section and the accumulated displacement index of the detected road section. The invention greatly reduces the detection cost of the road surface evenness, and shortens the detection cycle to the greatest extent.

Description

technical field [0001] The invention relates to the detection of road surface roughness information, in particular to a mobile terminal-based road surface smoothness detection method and an intelligent road surface information real-time monitoring system. Background technique [0002] Since the "Eleventh Five-Year Plan", the scale of my country's highway construction has achieved 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. As our country enters the period of large-scale construction of expressways, the era of large-scale expressway maintenance will follow. It is of great practical significance to establish a "highway maintenance management system" and accelerate the construction of highway management information. [0003] As the core part of the highway maintenance management system, the detection and evaluation of pavement quality is a...

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
