[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] In the attached diagram, all identical reference numerals refer to the same components.

[0021] like Figure 1-2 As shown, this utility model provides an intelligent monitoring system for dikes, comprising:

[0022] A monitoring base 2 is installed on top of the main body 1 of the dam. The monitoring base 2 contains a control terminal and a communication terminal. An optical fiber network is distributed inside the main body 1 of the dam. Distributed optical fiber sensors 11 and fiber Bragg grating sensors 12 are installed at the bottom of the monitoring base 2. Each of the distributed optical fiber sensors 11 and the fiber Bragg grating sensors 12 is individually connected to the optical fiber network.

[0023] The main body of the dam 1 is equipped with a monitoring component, which is electrically connected to the control terminal and the communication terminal.

[0024] Furthermore, the monitoring components include a steel wire pore water pressure gauge 3, a guide wheel inclinometer 4, a piezometer 5, an earth pressure gauge 6, a water level gauge 7, a water level and flow detector 8, a tipping bucket rain gauge 9, and a machine vision intelligent measuring instrument 10. A water level and flow detector 8 is installed on one side of the top of the dam body 1, and a tipping bucket rain gauge 9 is installed on the other side of the top of the dam body 1.

[0025] Furthermore, a machine vision intelligent measuring instrument 10 is installed on one side of the monitoring base 2, with the machine vision intelligent measuring instrument 10 facing the right slope.

[0026] Furthermore, two sets of pressure measuring tubes are buried at the top of the main body 1 of the dam, and steel wire type pore water pressure gauges 3 are installed inside the pressure measuring tubes. Two inclinometer tubes are buried at the waist of the main body 1 of the dam, and guide wheel type inclinometers 4 are installed in the upper part of the inclinometer tubes.

[0027] Furthermore, a seepage pipe is buried in the middle section of the waist of the main body 1 of the dam, and a seepage gauge 5 is installed inside the seepage pipe. An earth pressure gauge 6 is buried in the lower section of the waist of the main body 1 of the dam. Two sets of steel wire pore water pressure gauge 3, guide wheel inclinometer 4, seepage gauge 5 and earth pressure gauge 6 are all installed.

[0028] Furthermore, a water level gauge 7 is installed on one side of the main body of the dam 1.

[0029] Working principle: By monitoring changes in pore water pressure using a steel wire pore water pressure gauge 3, the stability of the soil inside the dike can be determined. This helps prevent the weakening of the shear strength of the dam body or foundation materials due to increased pore water pressure, thus affecting the stability of the dike.

[0030] The distributed optical fiber sensor 11 provides the spatial distribution of seepage, while the fiber optic grating sensor 12 and the steel wire pore water pressure gauge 3 verify local water pressure changes. Combined with water level data, it realizes a three-level early warning system of "surface-line-point", provides continuous monitoring data along the optical fiber path, improves monitoring accuracy and range, enhances anti-interference capability, and improves data stability.

[0031] The guide wheel inclinometer 4 can monitor the horizontal displacement of the soil at different depths in real time, thereby assessing the deformation and stability of the embankment. The guide wheel design makes the measurement more accurate and stable, and is suitable for long-term monitoring.

[0032] After the distributed optical fiber sensor 11 detects an abnormal strain area, it uses the guide wheel inclinometer 4 and fiber optic grating sensor 12 for point verification and machine vision to verify surface cracks, forming a closed loop of "wide-area screening → precise positioning → surface confirmation". The fiber optic grating sensor 12 monitors the minute deformation of the dike, improving monitoring accuracy; it also enables remote monitoring and reduces the cost of manual inspection.

[0033] By installing a piezometer 5, changes in seepage pressure inside the dike can be monitored, abnormal seepage can be detected in a timely manner, and dike damage caused by seepage can be prevented.

[0034] The piezometer 5 and fiber optic grating sensor 12 monitor the seepage pressure and flow rate changes of the dike, providing high-precision seepage pressure monitoring data. Combined with the distributed fiber optic sensor 11, they can achieve multi-point synchronous monitoring.

[0035] By using earth pressure gauges 6 embedded inside the dike, changes in soil compressive stress can be monitored in real time, allowing for the assessment of the dike's bearing capacity and stability.

[0036] The distributed optical fiber sensor 11 locates the abnormal stress zone, while the fiber optic grating sensor 12 and the traditional earth pressure gauge 6 provide verification data to guide targeted reinforcement. By monitoring changes in earth pressure through the fiber optic grating sensor 12, the monitoring accuracy and response speed are improved, and the anti-interference capability of the data is enhanced.

[0037] During the flood season, the data from the water level gauge 7 is crucial for predicting flood arrivals and developing flood control measures. By monitoring water level changes in real time, abnormal rising or falling trends can be detected promptly, allowing for timely adjustments and responses.

[0038] The distributed fiber optic sensor 11 can realize multi-point synchronous monitoring. By using the distributed fiber optic sensor 11 and the water level gauge 7 to assist in monitoring water level and flow changes, the monitoring accuracy and response speed can be improved; remote monitoring can be realized, which facilitates centralized data management.

[0039] The water level and flow rate detector 8 has both water level and flow rate monitoring functions. By monitoring changes in water level and flow rate, a more comprehensive understanding of the hydrological conditions near the dike can be obtained, providing decision support for flood control scheduling and water resource management.

[0040] Furthermore, the monitoring accuracy and response speed are further improved by using distributed optical fiber sensors 11 to assist in monitoring water level and flow changes.

[0041] In levee monitoring, the tipping bucket rain gauge can monitor changes in rainfall in real time, providing strong support for flood warning. By accurately measuring rainfall, the impact of rainfall on levees can be assessed, allowing for timely flood control measures.

[0042] The distributed fiber optic sensor 11 can monitor the impact of rainfall on the dike, such as changes in soil moisture. The data can be combined with the data monitored by the tipping bucket rain gauge 9 to ensure the accuracy of the monitoring data.

[0043] The machine vision intelligent measuring instrument 10 can be used in levee monitoring to achieve real-time monitoring of levee surface features such as cracks and deformation through image recognition and processing technology. This improves the accuracy and efficiency of monitoring, allows for the timely detection of potential levee problems, and provides a scientific basis for levee maintenance and management.

[0044] The distributed fiber optic sensor 11 can be used to monitor internal changes in the dike structure, such as crack propagation. It is combined with the data monitored by the machine vision intelligent measuring instrument 10 for analysis. The machine vision intelligent measuring instrument 10 is mainly used to monitor appearance problems, while the distributed fiber optic sensor 11 monitors internal structural changes. The combination of the two can achieve comprehensive internal and external monitoring.

[0045] Furthermore, through the cooperation of the control terminal and the communication terminal, real-time input and output of monitoring data were achieved.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
