Description

Technical Field

[0001] This invention belongs to the field of bridge safety monitoring technology, specifically relating to an intelligent monitoring system for bridge collapse scenarios. Background Technology

[0002] Bridges are structures used to cross rivers, valleys, or other transportation lines, such as railways, roads, canals, and pipelines. During their use, they are subjected to repeated loads and erosion from the natural environment, which can lead to material fatigue damage. This can gradually reduce the safety performance of bridges and, in severe cases, even cause them to collapse. In order to understand the usage status of bridges in a timely manner and take appropriate measures, it is necessary to monitor the usage status of bridges in real time.

[0003] Chinese Patent No. 202210563906.9 discloses a bridge monitoring system based on multi-source data fusion, which includes the following modules:

[0004] The data acquisition module acquires the commonly inspected images corresponding to the commonly inspected coordinates based on the image acquisition device, and acquires the load data of the target bridge based on the deep inspection signal test. The load data includes static load data and dynamic load data.

[0005] The data analysis module determines the frequently detected locations based on the bridge model, converts these locations into frequently detected coordinates, analyzes the frequently detected images, and determines whether to generate a deep detection signal based on the analysis results. It also analyzes static load data using a static load standard curve to obtain static load analysis labels, analyzes dynamic load data using an intelligent evaluation model to obtain dynamic load analysis labels, and determines the state of the target bridge based on the dynamic load analysis labels and / or static load analysis labels. The intelligent evaluation model is obtained by training an artificial intelligence model using standard training data. The data analysis module analyzes the frequently detected images and determines whether to generate a deep detection signal based on the analysis results. This includes: identifying anomalies in the frequently detected locations in the images using image recognition algorithms, analyzing the number and distribution of abnormal frequently detected locations, and determining whether to generate a deep detection signal based on the analysis results.

[0006] The inventors of this application have discovered that the existing bridge monitoring system based on multi-source data fusion can only determine whether a deeper inspection is needed for the routine inspection locations of the bridge and monitor the bridge status during the deeper inspection, but cannot monitor the bridge status at all times. In some cases, the collapse of the bridge may occur during the interval between two inspections. Therefore, the effectiveness of bridge safety monitoring still needs to be improved. Summary of the Invention

[0007] To address the problems mentioned in the background section, this invention provides an intelligent monitoring system for bridge collapse scenarios. This system enables continuous monitoring of bridges throughout the entire time period, improving the comprehensiveness and safety effectiveness of bridge monitoring.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an intelligent monitoring system for bridge collapse scenarios, comprising: a first data acquisition module, a first data processing module, a simulated bridge construction module, a second data acquisition module, a second data processing module, a third data acquisition module, a third data processing module, a fourth data acquisition module, a fourth data processing module, a first data storage module, a fifth data acquisition module, a fifth data processing module, and an early warning module, wherein:

[0009] The first data acquisition module collects as-built data, inspection and evaluation data, and surrounding environmental information of the bridge to be monitored.

[0010] The first data processing module identifies the type of reinforced concrete used in the construction of the bridge under monitoring through the as-built data, identifies the load-bearing capacity specified in the construction of the bridge under monitoring through the test and evaluation data, and identifies the environmental information around the bridge under monitoring, including temperature and humidity, through the surrounding environmental information data.

[0011] The simulated bridge construction module can construct multiple simulated bridges with the same type of reinforced concrete, load-bearing capacity, and environmental information as the bridge to be monitored.

[0012] The second data acquisition module collects load and reinforced concrete fatigue strength data of multiple simulated bridges under test without environmental information influence.

[0013] The second data processing module calculates the correlation between the fatigue strength of each load at different stages of the bridge by using load and reinforced concrete fatigue strength data from multiple simulated bridges.

[0014] The third data acquisition module collects fatigue strength data of reinforced concrete for multiple simulated bridges under no-load influence experiments.

[0015] The third data processing module calculates the correlation between the environmental information and the fatigue strength of the bridge at different stages using environmental information and reinforced concrete fatigue strength data from multiple simulated bridges.

[0016] The fourth data acquisition module collects fatigue strength data of reinforced concrete from multiple simulated bridges under natural environmental tests, including load and environmental information.

[0017] The fourth data processing module establishes a fitting curve of collapse risk level - reinforced concrete fatigue strength as a comparison template, and divides the fitting curve into safe interval, warning interval and dangerous interval respectively;

[0018] The first data storage module stores the aforementioned comparison template;

[0019] The fifth data acquisition module collects real-time load data and environmental information data of the bridge;

[0020] The fifth data processing module clarifies the time period for collecting bridge load data and environmental information data. By calculating the fatigue strength associated with the load in each period and the fatigue strength associated with the environmental information in each period, it calculates the influence of the load on the bridge fatigue strength. The collected bridge fatigue strength data are connected into a curve, and this curve is compared with the collapse risk degree-reinforced concrete fatigue strength fitting curve of the above comparison template. If the highest point of the curve is lower than the highest point of the safe zone, no warning is issued. If it is higher than the highest point of the safe zone but lower than the highest point of the warning zone, a first-level warning is issued. If it is higher than the highest point of the warning zone but lower than the highest point of the danger zone, a second-level warning is issued.

[0021] The early warning module issues corresponding warnings based on the data processing structure of the fifth data processing module.

[0022] Preferably, the early warning module includes a pop-up warning on the monitoring site's large screen and an audio warning via a mobile early warning app for monitoring personnel.

[0023] Preferably, it also includes a 3D modeling module and a 3D model display module, wherein:

[0024] The 3D modeling module receives the as-built data, inspection and evaluation data and surrounding environmental information of the bridge to be monitored collected by the first data acquisition module, clarifies the environmental information of the bridge and the surrounding buildings, and performs 3D modeling of the bridge and surrounding buildings. At the same time, it receives the bridge and surrounding building information collected in real time by the fifth data acquisition module and performs 3D modeling of the bridge's real-time status and surrounding buildings.

[0025] The 3D model display module displays the 3D model of the bridge and surrounding buildings constructed by the 3D modeling module in real time, so as to understand the condition of the bridge in a timely manner and take timely action.

[0026] Preferably, it also includes a maintenance data database, in which:

[0027] A maintenance data database stores maintenance measures for bridges at various fatigue strengths.

[0028] The fourth data processing module also includes associating the maintenance measures in the maintenance data database with the corresponding nodes of the warning interval and the danger interval of the collapse risk degree-reinforced concrete fatigue strength fitting curve.

[0029] The fifth data acquisition module extracts the maintenance measures for the corresponding points of the curve endpoint and the comparison template to the three-dimensional model display module;

[0030] The 3D model display module shows the maintenance measures for the corresponding point of the curve endpoint and the comparison template when the bridge fatigue strength enters the warning period.

[0031] Preferably, it also includes a sixth data acquisition module, wherein:

[0032] The sixth data acquisition module studies the collapse of each node of the bridge by applying different loads to the bridge construction module, and collects the failure path and failure range data of each node. The three-dimensional modeling module receives the collected failure range data of each node, models the failure range data of each node of the bridge, and displays it on the three-dimensional model display module with a red warning zone.

[0033] The 3D model display module is accessible via a shared login password, allowing it to be viewed simultaneously by various municipal engineering departments. This enables subsequent construction to avoid the area affected by bridge collapse.

[0034] Preferably, it also includes a seventh data acquisition module, wherein:

[0035] The seventh data acquisition module collects the location of people using existing buildings within the area affected by the bridge collapse;

[0036] The early warning module also includes a voice warning for the mobile phone early warning APP of the existing building users. Within a preset time period before the bridge collapse, the early warning APP of the users located within the bridge collapse damage range is sent according to the location of the users collected by the seventh data acquisition module, so as to help the users evacuate quickly and avoid injury.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] 1. This invention is based on constructing multiple simulated bridges with the same reinforced concrete type, load, and environmental information as the bridge to be monitored. It calculates the fatigue strength correlation of each load and environmental information at different stages of the bridge. Then, it calculates the real-time fatigue strength by comparing the real-time monitored load data with the calculated fatigue strength correlation of each load and environmental information at each stage. Finally, it compares the fatigue strength curve with the generated comparison template to determine the degree of bridge collapse risk and provides an appropriate level of early warning. This achieves intelligent monitoring of common bridge collapse issues, enabling monitoring at all times and improving the system's comprehensiveness and safety monitoring effect.

[0039] 2. This invention performs three-dimensional modeling based on the collected information, and updates the data in real time based on the collected load and fatigue data, so that monitoring personnel can understand the bridge's usage status and take timely action.

[0040] 3. The present invention has specific maintenance measures associated with each fatigue strength node.
