Technical Field

[0001] The utility model relates to the technical field of bridge health monitoring, and in particular to an intelligent bridge inspection system. Background Art

[0002] As bridges are subject to the influence of vehicle loads, erosion of the natural environment, and aging of materials for a long time, bridge structures are prone to diseases such as cracks, corrosion, and deformation. If these problems are not discovered and handled in time, they may cause serious safety accidents. Therefore, regular inspection and maintenance of bridges are key measures to ensure their safety and durability. Traditional bridge inspections are mainly carried out manually, which has problems such as high labor intensity and low efficiency. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is the overall architecture diagram of the bridge intelligent inspection system of the preferred embodiment of the utility model;

[0014] Figure 2 Schematic diagram of the communication method of the Liang smart inspection system of the preferred embodiment of the utility model. DETAILED DESCRIPTION

[0015] The bridge smart inspection system mainly includes video monitoring subsystem, bridge health monitoring subsystem, background monitoring server, bridge smart inspection management terminal and bridge smart inspection client. Figure 1 As shown, the background monitoring server is respectively connected to the video monitoring subsystem, the bridge health monitoring subsystem, the bridge smart inspection management terminal and the bridge smart inspection client.

[0016] like Figure 2 As shown in the figure, the video surveillance subsystem includes a high-definition dome camera, a hard disk video recorder, and a 4G router. The high-definition dome camera needs to be scientifically and reasonably arranged on the bridge to ensure that the inspection area of ​​the bridge is fully covered and that there is no blind spot monitoring. According to the location and number of the high-definition dome cameras, the hard disk video recorders are scientifically and reasonably arranged to complete the on-site line integration of the high-definition dome cameras economically and efficiently. The hard disk video recorder achieves Internet access through the 4G router, thereby sending the inspection images of the high-definition dome camera to the background monitoring server in real time.

[0017] like Figure 2 As shown in the figure, the bridge health monitoring subsystem includes sensors, IoT data acquisition modules and IoT gateways. Sensors are deployed at key load-bearing sections of the bridge and are wired one-to-one with the IoT data acquisition modules to collect mechanical parameter information of the bridge structure itself. After the IoT data acquisition module completes data acquisition, it transmits the data to the IoT gateway with the help of LoRa communication technology. Subsequently, the IoT gateway further forwards the data to the background monitoring server through 4G communication.

[0018] The intelligent inspection management terminal of bridges includes four functional modules: home page, bridge management, inspection record and role management. The home page displays statistical information such as the number of inspection bridges connected to the system, the number of connected sensors, the number of connected high-definition spherical cameras and the number of defects. The bridge management module displays basic information such as the name, number, management unit, area, traffic status, BIM model upload status and creation time of each bridge connected to the system, and each bridge supports the editing of the above basic information, and supports the annotation of sensors and high-definition spherical cameras on the bridge BIM model. The inspection record module displays the name of the inspected bridge, the inspector, the inspection unit, the inspection time, the defects found during the inspection, and supports the export of inspection record reports. The role management module is mainly used to create users and assign permissions. Different users are matched with different functional permissions to ensure the orderly operation of the system.

[0019] The intelligent bridge inspection client includes four functional modules: bridge data, bridge inspection, inspection record and structural monitoring. The bridge data module displays the basic information of the bridge, inspection status, existing diseases, treated diseases and diseases found today. The bridge inspection module supports online disease inspection and disease treatment. By clicking on the high-definition spherical camera, inspectors can inspect the preset inspection points online. At the same time, it supports the operation of the camera's perspective including direction, and view the perspective outside the inspection point, so as to realize the comprehensive and free inspection of bridge diseases and add new diseases found during the inspection. In addition, the inspector can click on the disease mark in the BIM model, click the disease treatment button, fill in the valid data in the pop-up window, and complete the single disease treatment operation. The inspection record module can view all the inspection records of the bridge, and can export and batch export the inspection records to facilitate data management and analysis. The structural monitoring module supports viewing the monitoring data of each key parameter of the bridge and viewing the current early warning status of the bridge so as to deal with safety hazards in a timely manner.

[0020] As can be seen from the above, the main function of the bridge smart inspection management terminal is to manage bridges and system users. The addition and deletion of bridges can be achieved on the management terminal, and the addition, deletion and permission allocation of personnel can also be achieved on the management terminal. The functions of the bridge smart inspection client are concentrated on the online inspection and structural monitoring of the inspection personnel, and do not involve management functions such as bridges and personnel permission allocation. This system concentrates management authority on the bridge smart inspection management terminal, which can avoid some misoperations of the inspection personnel during the online inspection of the bridge, and focus more on the inspection and structural monitoring of the bridge, effectively preventing and controlling unauthorized access and data security risks.

[0021] In the entire bridge intelligent inspection system, the background monitoring server is mainly responsible for data processing, analysis and storage, and is the link between various subsystems.

[0022] The utility model can realize online inspection through the intelligent bridge inspection system, thereby reducing the manual labor intensity of bridge inspection and improving the inspection efficiency.

[0023] The utility model provides a bridge intelligent inspection system with high-definition cameras in each inspection area of ​​the bridge. The monitoring angle of the high-definition cameras can be adjusted through the bridge intelligent inspection client to conduct a comprehensive inspection of bridge defects.
