Abstract

The invention discloses a long-term real-time monitoring system for structural information of an airport asphalt pavement based on trigger acquisition and wireless transmission, belonging to the technical fields of monitoring and wireless transmission. The invention aims to construct a monitoring system for structural information of an airport asphalt pavement and solve the problems that the traditional monitoring system can continuously acquire mass data, however, a great number of monitored data can not be properly processed and utilized, no effective data can be obtained, and the real-time property for monitoring the structural information of the airport asphalt pavement is poor because the data acquisition is limited. All sensors are arranged in a connecting passage; a fiber grating demodulator, a wireless router and a first large volume hard disk are all arranged in an optical fiber collection box in lawn regions at two sides of a road shoulder; a camera and a first high-power wireless access device are both arranged on a box body supporting column; the trigger acquisition of all the sensors is realized by the fiber grating demodulator; the wireless router is respectively connected with the fiber grating demodulator, the camera, the large volume hard disk and the first high-power wireless access device so as to be used for wirelessly transmitting data so that the data is analyzed. The long-term real-time monitoring system can be used for monitoring airport pavements.

Description

technical field [0001] The invention relates to a long-term real-time monitoring system for airport asphalt pavement structure information. The invention belongs to the technical field of monitoring and wireless transmission. Background technique [0002] It is extremely important to have a true grasp of the inner workings of the airport pavement. As an external structure, the pavement structure system of the airport not only has a complex structure and various material properties, but also is subject to the repeated action of the external environment and loads. In the natural state, it is a complex system under the coupling of humidity, temperature and loads. , under the long-term repeated action of moisture and temperature, its internal working state is inevitably affected, which is reflected in the reduction of macroscopic performance. Therefore, it is necessary to timely grasp the basic stress-strain, temperature and humidity information inside the pavement under natur...
