Bridge structure health monitoring system based on big data

Abstract

The invention discloses a bridge structure health monitoring system based on big data. The bridge structure health monitoring system comprises a bridge detection module, a temporary data storage module, a cloud data transmission module, a server, a data analysis module, a remote inspection module, an alarm module, an external power supply module and a client. The bridge structure health monitoringsystem can perform real-time calculation, can know the health condition of a certain position of the bridge structure at any time, and is high in timeliness; according to the bridge structure healthmonitoring system, when a certain position of the bridge structure has a health condition, the corresponding crack lamp and the corresponding strain lamp can display corresponding colors, so that thehealth condition of the bridge structure is more intuitive and clearer; the bridge structure health monitoring system transmits the picture of the crack problem position of the bridge structure in real time, performs contour identification on the shadow part on the picture, and transmits the picture to the client, so that a user can know the crack condition and make a maintenance scheme in time, and the maintenance difficulty is reduced.

Description

technical field [0001] The invention relates to the field of bridge monitoring systems, in particular to a bridge structure health monitoring system based on big data. Background technique [0002] Bridge structure health monitoring is based on the bridge structure as a platform, using modern electronic communication and network technology, through the data acquisition system to timely obtain the response information of the bridge structure under various loads and actions, and realize the bridge structure through the analysis and processing of information. Real-time tracking and monitoring of health status provides a basis for the operation and maintenance of bridge structures. [0003] The patent application number CN201310576306.7 discloses a bridge structure health monitoring system, including a power management power supply, a data acquisition unit, a data processing unit, and a data transmission unit. , the data transmission unit is connected, the data acquisition unit...

Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a bridge structure health monitoring system based on big data: (1) by installing crack monitoring sensors and strain sensors at different positions of the bridge structure, the bridge detection module passes through cracks Monitoring sensors and strain sensors perform real-time monitoring to obtain monitoring data and installation locations. The server calculates the crack change value and the total strain value through the monitoring data. The data analysis module analyzes the crack change value and the total strain value to perform hazard warning classification and judge The health status of the installation location solves the problem that the existing bridge structure health monitoring system cannot know the health status of a certain position of the bridge structure at any time, and the timeliness is not high; (2) the result of grading the danger warning through the server And the installation location in the monitoring information is sent to the client, the server generates the corresponding alarm command according to the result of the danger warning classification, and transmits the corresponding alarm command to the alarm module, and the alarm module generates the corresponding display after receiving the corresponding alarm command The color instruction is transmitted to the crack lamp and the strain lamp to display the corresponding color for alarm, which solves the problem that the existing bridge structure health monitoring system only monitors but does not warn, making the health status of the bridge structure not intuitive and clear; (3) After receiving the first-level cracks, second-level cracks, third-level cracks and installation positions transmitted by the server through the client, an inspection instruction is generated, and the inspection instruction and the corresponding installation location are transmitted to the remote inspection module, and then remote inspection After receiving the inspection instruction, the module generates a shooting instruction, transmits the shooting instruction to the high-definition camera at the corresponding installation location, and controls the corresponding high-definition camera to take photos. The high-definition camera sends the photos taken to the photo analysis unit to enlarge the photos Several times, select the shadow part in the photo, and carry out outline marking on the selected shadow part, get the detection photo, and transmit the detection photo to the client, which solves the problem location detected by the existing bridge structure health monitoring system Finally, the maintenance personnel need to carry out inspection and measurement first, and discuss the solution before proceeding with the maintenance. The maintenance process is complicated and the maintenance is difficult.
