[0002] As an important part of urban transportation, the safety of bridges is directly related to the overall safe operation of the city. At present, there are numerous bridges in each city. Bridges are eroded by the natural environment for a long time and are also affected by external forces such as vehicles and pedestrians, which are prone to cause structural damage and performance degradation. Therefore, it is necessary to manage the safety of bridges, and reasonable maintenance and management can extend the service life of bridges. At present, the daily bridge management work mainly includes daily inspections, regular inspections, special inspections, and daily maintenance and repair work, etc. The traditional bridge management is carried out manually by inspectors. The inspection means are obviously relatively backward, the inspection results are inaccurate, and the efficiency is extremely low, which cannot meet the needs of modern bridge management. A new generation of sensing technology has emerged for collecting bridge operation data. Existing bridges have begun to deploy relevant sensors to collect bridge operation data for bridge safety monitoring. However, there are many types of sensors involved in bridges at present, and the data types, formats, and protocols generated by each sensor are different. It is necessary for the backend data management system to integrate multiple data interfaces, which undoubtedly increases the cost and difficulty of bridge data management.

[0096] The six-element monitor 4.1 is arranged at the upper part of the bridge deck module 6 of the bridge body;

[0097] The six-element monitor 4.1 includes a temperature sensor, a humidity sensor, an anemometer, a wind vane, a wind pressure gauge, a rain gauge and a visibility laser sensor;

[0098] The temperature sensor, the humidity sensor, the anemometer, the wind vane, the wind pressure gauge, the rain gauge, the visibility laser sensor and the bridge deck state remote sensing collection unit are all connected to the bridge meteorological environment data collection controller 14;

[0099] The bridge meteorological environment data collection controller 14 is connected to the bridge data management module 1;

[0100] It should be noted that the six-element detector 4.1 monitors the temperature, humidity, wind speed, wind direction, wind pressure and rainfall in the area where the bridge body is located; the bridge deck state remote sensing collection unit 4.2 monitors the visibility in the area where the bridge body is located, and timely judges the visibility level of the bridge body in rainy and foggy weather, providing guarantee for driving safety;

[0101] The bridge video data collection module 5 is connected to the bridge video data collection controller 15;

[0102] The bridge video data collection module 5 adopts a video surveillance camera 5.1;

[0103] The video surveillance camera 5.1 is installed at the bridge deck module 6 of the bridge body, and the height from the road surface is greater than the set distance;

[0104] The video surveillance camera 5.1 is connected to the bridge video data acquisition controller 15;

[0105] The bridge video data acquisition controller 15 is connected to the bridge data management module 1;

[0106] It should be noted that the video surveillance camera monitors the traffic conditions on the bridge deck, timely obtains the traffic conditions on the bridge deck, and analyzes the extreme working conditions of the bridge deck load.

[0107] In some embodiments, the inclination monitoring points are set at the connection position between the top of the bridge pier 10 of the bridge body and the bearing 8;

[0108] It should be noted that the bridge pier 10 of the bridge body is prone to tilt due to factors such as vehicle impact, uneven settlement of the foundation, and uneven lateral pressure of the pile foundation soil, which may cause the instability and overturning of the beam body and pose a major safety risk. Therefore, an inclination sensor is installed on the top of the bridge pier 10 to monitor the inclination of the bridge pier 10 and reflect the inclination condition of the bridge pier 10 in real time; there are structural cracks in the bridge deck module 6;

[0109] The crack monitoring points are set at the structural cracks;

[0110] It should be noted that the bridge body may generate structural cracks during operation, and the structural cracks have the risk of causing the bridge body to break. Therefore, it is necessary to install a crack gauge 2.3 to monitor the crack width in real time, identify risks in advance, and ensure the safety of the bridge;

[0111] The vibration monitoring points are set on the surface of the bridge deck module 6;

[0112] The vibration acquisition unit 2.6 uses an acceleration sensor;

[0113] It should be noted that the vibration state of the whole bridge body and local components is collected through the acceleration sensor;

[0114] The deflection monitoring points are set at the middle or both ends of the bridge body;

[0115] The deflection measuring device 2.7 includes an optoelectronic deflection meter and a static level.

[0116] In some embodiments, the displacement sensor 2.2 includes a lateral displacement sensor, a longitudinal displacement sensor, and a vertical displacement sensor;

[0117] The bridge pier 10 includes a single-column pier;

[0118] The load-bearing beam 7 includes several sub-beams; at least one sub-beam is arc-shaped;

[0119] Each sub - beam is spliced in sequence to form the integral load - bearing beam 7;

[0120] At the connection position between the arc - shaped sub - beam and the support 8, at the splicing position of two sub - beams, and at the connection position between the support 8 of the single - column pier and the load - bearing beam 7, splicing joints are provided;

[0121] The displacement monitoring points are set at the splicing joints;

[0122] The lateral displacement sensor, longitudinal displacement sensor, and vertical displacement sensor are set at the displacement monitoring points;

[0123] It should be noted that the support 8, as the connecting member between the load - bearing beam 7 and the bridge pier 10, plays the role of buffering the impact load of vehicles and offsetting the lateral, longitudinal, and vertical displacements between the load - bearing beam 7 and the bridge pier 10 caused by the linear expansion of the structure due to temperature rise and fall. Once the displacement exceeds the limit, the support 8 will fail, and the load - bearing beam 7 will face risks such as lateral sliding and beam dropping. Therefore, the lateral, longitudinal, and vertical displacements of the support 8 are monitored at the positions where the support 8 is prone to displacement, such as at the arc - shaped sub - beam, single - column pier, and expansion joint positions, to timely detect the signs of support 8 failure and ensure the safety of the bridge.

[0124] In some embodiments, the stress monitoring points are set at the positions where the stress response of the bridge body structure is the largest;

[0125] It should be noted that the static strain of the bridge body reflects the local stress state of the structure. Abnormal local static strain, excessive or too small strain, or discontinuous strain values indicate local stress concentration or the occurrence of structural cracks in the structure. Therefore, by determining the position where the stress response of the bridge body is the largest and installing the static strain gauge 2.4 to monitor the local stress of the structure, the abnormal stress conditions can be detected in time;

[0126] Under the action of vehicle loads, the strain response characteristic of the bridge body is that the structure deforms rapidly and recovers rapidly. To better capture the strain response of the structure under vehicle loads, a dynamic strain gauge 2.5 is installed at the position where the stress response of the bridge body is the largest to monitor the real - time strain response of the structure, which supplements the static trend response of the static strain and comprehensively reflects the structural response of the structure under loads;

[0127] In some embodiments, the bridge structure data acquisition module 2 further includes a corrosion probe 2.8;

[0128] The bridge pier 10 is internally provided with steel bars;

[0129] The corrosion probe 2.8 is set at the position of the steel bars at the lower end of the bridge pier 10;

[0130] It should be noted that due to the structure of the bridge body, the steel in the salt spray environment is prone to corrosion, resulting in the failure of the steel to function and the reduction of the structural load-bearing capacity, which may lead to installation risks. Therefore, for the bridge body in the sea area, corrosion probes 2.8 are installed to monitor the corrosion potential between the steel and concrete of the bridge body. The corrosion condition of the structure is reflected by the magnitude of the potential, or corrosion probes 2.8 are installed on the surface of the steel structure to monitor the remaining thickness after corrosion to reflect the corrosion condition.

[0131] In some embodiments, a cable-stayed structure is further provided on the bridge body;

[0132] A cable force monitoring point is provided at the cable-stayed structure, and a cable force acquisition unit 2.9 is arranged at the cable force monitoring point. The cable force acquisition unit 2.9 uses an acceleration sensor;

[0133] It should be noted that for the bridge body with a cable-stayed structure, the cable force value of the stay cable is obtained by collecting the relationship between the vibration of the bridge body and the cable force through a vibration sensor, so as to identify the abnormal cable force condition of the stay cable through the cable force monitoring of the stay cable and avoid safety incidents caused by the breakage of the stay cable.

[0134] In some embodiments, the traffic flow acquisition unit 3.1 includes an induction coil, a camera and a processor; the processor is connected to the induction coil and the camera;

[0135] It should be noted that the traffic flow acquisition unit 3.1 obtains traffic flow data by collecting the number of passing vehicles; the vehicle load acquisition unit 3.2 uses a quartz sensor;

[0136] It should be noted that the vehicle load acquisition unit 3.2 obtains vehicle load data through data such as the axle weight and the number of axles of the vehicle;

[0137] The vehicle and ship impact acquisition unit 3.3 uses a three-phase accelerometer;

[0138] It should be noted that in transportation, for the bridge body with cross-line sections or waterways, the load-bearing beam 7 and the bridge pier 10 are prone to be impacted by vehicles and ships, resulting in safety risks such as the deviation, inclination and damage of the load-bearing beam 7 and the bridge pier 10. For the bridge body without an under-bridge waterway, a three-phase accelerometer is installed on the load-bearing beam 7 and the bridge pier 10 to monitor the vehicle impact situation;

[0139] The seismic load acquisition unit 3.4 uses a strong motion seismograph;

[0140] It should be noted that the strong motion seismograph monitors the seismic load.

[0141] In some embodiments, the impact monitoring point is set at the bridge pier 10 of the bridge body.
