Abstract

The invention discloses a road surface deformation monitoring method, which belongs to the technical field of intelligent transportation. The road surface deformation monitoring method is characterized by comprising the following steps of: a, determining a reference value according to an initial condition, and performing information interaction between monitoring devices and a server through a relay and a gateway; B, detecting pavement settlement and deformation through angle changes of attitude sensors in the monitoring devices; C, enabling the gateway to obtain a network relation mapping graph from the server, issuing the network relation mapping graph step by step according to a jurisdiction relation, completing relation mapping, and uploading posture data collected in real time to the server through the relay and the gateway through a Bluetooth network by utilizing the monitoring devices; and D, comparing attitude data acquired by the plurality of groups of monitoring devices with a reference value and historical data respectively by using the server, and acquiring a damage type and a damage range of the road section through model establishment and data analysis. According to the road surface deformation monitoring method, monitoring data can be uploaded in real time, pavement state monitoring and early warning are carried out through modeling and data analysis, and pavement settlement and displacement conditions are effectively monitored.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a road surface deformation monitoring method. Background technique [0002] Pavement damage status is an important index in road condition investigation and evaluation, and the pavement damage status is described by damage type, severity and scope. There is a certain relationship between the smoothness of the road surface and the smoothness of each level of the road surface, that is, the leveling effect of each level will be reflected on the surface of the road surface cumulatively. Water seepage in the foundation, uneven subsidence of the subgrade, longitudinal deformation and longitudinal cracks will appear, and wave-like unevenness will occur on the top layer of the road surface, especially for roads that have been open to traffic for many years; excessive road settlement and cracks that are too long and too wide will seriously affect the quality of the road...
