Embodiment Construction

[0073] The present invention will be further described in detail below in conjunction with examples.

[0074] The full-scale loop test is loaded for 10 hours a day, 6 loading vehicles are loaded at the same time, the sensor collection frequency is 2000Hz, and the total amount of data generated is about 1TB per day.

[0075] According to the content of the present invention, the specific implementation steps are as follows:

[0076] (1) The dynamic acquisition unit sends the data file when the loading vehicle passes to the data aggregation server;

[0077] (2) The file reading module of the data parsing server obtains the data files from the data server one by one according to the time data;

[0078] (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;

[0079] (4) The waveform detection module performs dynamic response waveform detection according to the respo...

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 road internal stress and strain response data acquisition method and system for a full-scale road surface accelerated loading test loop. Background technique [0002] The characteristic state of the road internal structure is the most direct index to evaluate the road quality and estimate the road life. However, it is difficult to obtain the real state of the road internal structure in the actual road. In recent years, with the development of sensors and electronic information technology, in order to solve this bottleneck problem, people began to use stress and strain sensors embedded in the road to measure the mechanical response of the internal structure of the road, so as to measure the mechanical response of various roads through real response data. The mechanical model, inverse calculation method and principle hypothesis are verified. [0003] The f...
