Fabricated highway bridge pavement safety monitoring analysis method based on Internet of Things and big data

Abstract

The invention discloses a fabricated highway bridge pavement safety monitoring analysis method based on the Internet of Things and big data, and the method comprises the steps: carrying out the statistics and numbering of each bridge floor connection region of a fabricated bridge, and laying a plurality of detection points at each connection point in each connection region of the bridge floor of the fabricated bridge; collecting a gray image of each monitoring point in each bridge floor connection area, obtaining an image gap distance of each monitoring point in each bridge floor connection area, and calculating an actual gap distance difference value of each monitoring point in each bridge floor connection area; meanwhile, counting position coordinates of all monitoring points in all bridge floor connecting areas of the fabricated bridge, analyzing the offset distance of all the monitoring points in all the bridge floor connecting areas, calculating the bridge floor comprehensive safety influence coefficient of the fabricated bridge, if the bridge floor comprehensive safety influence coefficient exceeds a set threshold value, carrying out early warning reminding, and notifying related personnel to carry out blocking and overhauling treatment. Therefore, the fabricated bridge is prevented from losing the best opportunity for maintenance, and potential safety hazards of people in travel are reduced.

Description

technical field [0001] The invention relates to the field of bridge building safety monitoring, and relates to a method for monitoring and analyzing the safety of road surfaces of assembled highway bridges based on the Internet of Things and big data. Background technique [0002] With the continuous development of my country's prefabricated bridge construction, the safety of bridges has attracted more and more attention from all walks of life. The domestic prefabricated bridge deck connection monitoring and analysis technology has been continuously improved and gradually applied to the safety monitoring of bridge decks. It provides a technical guarantee to ensure the safe operation of bridges in our country and prolong the service life of bridges. [0003] At present, there are still some deficiencies in the existing prefabricated bridge deck connection safety monitoring technology. The existing prefabricated bridge deck connection safety monitoring is mainly through manual ...

Problems solved by technology

[0003] At present, there are still some deficiencies in the existing prefabricated bridge deck connection safety monitoring technology. The existing prefabricated bridge deck connection safety monitoring is mainly through manual monitoring, which has a low level of manual monitoring and lacks scientific and systematic methods. It is impossible to accurately monitor the gap distance at the connection points of the bridge deck, which leads to the reduction of the accuracy and reliability of the monitoring data, so that the safety status of the bridge deck connection of the prefabricated bridge cannot be comprehensively analyzed. As a result, the settlement of the bridge deck of the prefabricated bridge cannot be found in time, which leads to the loss of the best time for maintenance of the prefabricated bridge, thereby speeding up the process of damage to the prefabricated bridge and increasing the safety hazards of people's travel. In order to solve the above problems, A safety monitoring and analysis method for prefabricated highway bridges based on the Internet of Things and big data is now designed
