Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: See also Figure 1 The present invention provides a method for automatically monitoring dam body seepage, comprising the following steps: S1, sending the seepage weight data information collected by the weight sensor to the regional controller through the acquisition board; S2. The regional controller sends the data information to the management system, and the management system stores the data information in the database; S3, the management system calculates the seepage volume access time data, flow data and seepage volume data per unit time according to the transmitted seepage water weight data information, and stores the data in the database; S4, the management system collects the seepage data at each time node and pre-processes the collected data; S5. The management system conducts descriptive statistical analysis on the mean, median and standard deviation of the seepage volume; S6. The management system uses a chart tool to draw a line chart of seepage flow rate changing over time; S7. The management system performs trend analysis on the seepage data; S8. The management system predicts future changes in seepage volume.

[0022] In S1, a weight sensor and a collection board are provided in the water seepage collection device, the weight sensor is electrically connected to the collection board, and the collection board is communicatively connected to the regional controller. Specifically, the collection board is connected to the regional controller via the CANbus protocol, and the weight sensor sends the water seepage weight data in the water seepage collection device to the regional controller via the collection board. The CANbus protocol supports real-time data communication, ensuring that the collection board can quickly transmit the water seepage weight data collected by the weight sensor to the regional controller. The CANbus protocol has an error monitoring and arbitration mechanism, which can ensure the accuracy and reliability of data transmission and reduce the risk of data loss or errors.

[0023] In S2, the regional controller is connected to the management system for communication. The management system receives data from the regional controller and stores it in a database. The data storage includes a timestamp to record the specific time of each data record.

[0024] In S3, the management system calculates the seepage flow access time based on the transmitted seepage weight data ,flow And the seepage volume collected in the collection device within one minute .

[0025] In one of the schemes, the capacity of the seepage collection device is 400 ml. When the seepage volume reaches or exceeds 400 ml, the timestamp at that time is recorded. , duration is the timestamp from the first measurement arrive The time difference is obtained by the following formula: ; in, is the current timestamp, is the timestamp of when monitoring starts; The flow rate Obtained by the following formula:

[0026] in, Represented as a timestamp The weight of the collected seepage water; Represented as a timestamp The weight of the collected seepage water; Expressed as the density of water; Represented as a timestamp To timestamp time difference; The amount of seepage collected in the sampling device within one minute Obtained by the following formula: ; in, Expressed as a unit of time, that is, one minute.

[0027] The duration ,flow And the seepage volume collected in the collection device within one minute The data is stored in the database and the change trend of seepage volume over time is analyzed to predict possible risks and future flow changes, so as to facilitate the query and analysis of historical data.

[0028] In S4-S5, the management system analyzes the seepage change trend through the following steps: The management system collects hourly seepage data and pre-processes the collected data, including removing outliers, filling missing values, and data standardization; The management system performs descriptive statistical analysis on the mean, median and standard deviation of water seepage; The average water seepage value M of the management system is first summed up all the flow data, and the sum is divided by the number of data points to get the average value. The average value provides the center position of all data points in the data set and is obtained by the following formula: ; in, is the ith data point, is the total number of data points.

[0029] The median calculation is to arrange the data points in order of size. If the number of data points is an odd number, the median is the middle value; if the number of data points is an even number, the median is the average of the two middle values. The median is the center point of the data, which is not affected by extreme values ​​or outliers and is a robust measure of non-central tendency.

The management system extracts the seepage volume data and the corresponding timestamps from the database, and uses Python chart tools to draw these data points on the coordinate axis in chronological order to form a continuous line, thereby generating a line graph that visually displays the seepage volume over time. This graph can be integrated into the management interface, allowing users to perform interactive operations such as zooming and panning to view the data change trend of a specific time period in detail.

[0032] In S7, the trend of the data, including rising, falling or cyclical changes, is initially identified by visually inspecting the chart. The historical data of seepage volume is extracted and preprocessed from the database to ensure the accuracy and completeness of the data. The time series analysis method is used to identify the trend lines and cyclical patterns in the data. The ARIMA model is used to conduct in-depth analysis of the data to predict future seepage volume changes.

[0033] In S8, a time series analysis scheme is applied, and the ARIMA model is used to predict the future changes of the seepage volume. Specifically, historical seepage volume data is extracted from the database, and then the prediction model ARIMA is trained using the data, and the ARIMA model is used to predict the changes of the seepage volume in the future time period.

[0034] The present invention integrates a weight sensor and a seepage collection device connected to a regional controller via a CANbus communication protocol, and the regional controller is connected to a management system to achieve real-time monitoring of the seepage situation of the dam. The weight sensor is responsible for collecting seepage data, and the CANbus communication protocol ensures that these data can be quickly and accurately transmitted to the management system. The automated data collection and processing mechanism improves the monitoring efficiency of the seepage volume and reduces data errors caused by human operation.

[0035] On the other hand, the management system includes descriptive statistical analysis, which is used to preliminarily organize and analyze the collected seepage data to identify the basic characteristics and distribution of the data, and use the time series prediction model (ARIMA model) to predict the long-term trend of seepage, which helps to identify potential risk points.
