Embodiment Construction

[0074] Below in conjunction with example the present invention is described in further detail.

[0075] The full-scale loop test loading is carried out for 10 hours a day, 6 loading vehicles are loaded at the same time, the sensor acquisition frequency is 2000Hz, and the total amount of data generated is about 1TB per day.

[0076] According to content of the present invention, concrete implementation steps are as follows:

[0077] (1) The dynamic acquisition unit sends the data files when the loading vehicle passes to the data aggregation server;

[0078] (2) The file reading module of the data parsing server obtains data files from the data server one by one by time data;

[0079] (3) The data analysis module analyzes the format of the original data file to obtain the real-time response data of the internal stress and strain of the road structure;

[0080] (4) The waveform detection module detects the dynamic response waveform according to the response data of the stress s...

Abstract

The invention relates to a method for acquiring internal stress and strain response data of a full-scale accelerated pavement test loop road and a system thereof, and belongs to the field of road internal mechanical state detection. The method comprises the following steps: acquiring massive sensor data through a data acquisition unit at a front end, and transmitting the acquired massive sensor data to a data aggregation server; performing a series of processes such as parsing, screening and filtering on the data through each layer of data processing server at a back end; and finally storing the obtained stress and strain response information in a data array for subsequent road relevant researches.

Description

technical field [0001] The invention relates to the field of road internal mechanical state detection, in particular to a method and system for acquiring road internal stress and strain response data of a full-scale pavement accelerated loading test loop. Background technique [0002] The characteristic state of the internal structure of the road is the most direct index to evaluate the quality of the road and predict the life of the road. However, it is difficult to obtain the true state of the internal structure of the road in the actual road. In recent years, with the development of sensors and electronic information technology, in order to solve this bottleneck problem, people have begun to embed stress and strain sensors inside the road to measure the mechanical response of the internal structure of the road, so as to use real response data to analyze various roads. Mechanical models, inverse calculation methods and principle assumptions are verified. [0003] The full...
