[0014] The model building module is used to obtain monitoring data fed back by the monitoring equipment, divide the monitoring data into historical monitoring data and real-time monitoring data, the real-time monitoring data is the latest feedback monitoring data, and the historical monitoring data is the monitoring data other than the real-time monitoring data, and then establish an equipment health assessment model based on performance parameters and installation environment;

[0015] The health interval module is used to collect historical operation and maintenance records, and then input the historical operation and maintenance records into the health assessment model, and then the health assessment model outputs the health monitoring data interval of the corresponding monitoring equipment.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0038] See also Figure 1 As shown, the purpose of this embodiment is to provide an operation and maintenance management system for a seismic monitoring station, including a management module establishment unit 10, a health interval output unit 20, a maintenance time analysis unit 30, a time impact analysis unit 40 and a maintenance task dispatching unit 50;

[0039] The management module establishment unit 10 is used to establish an OA management module in the seismic monitoring station, and the OA management module obtains the performance parameters and installation environment of the monitoring equipment corresponding to each unattended station;

[0040] The management module establishment unit 10 establishes a data transmission link with the internal port of the seismic monitoring station, and then establishes an OA management module in the internal port. The OA management module has a built-in task release block and a task completion block. By feedback of the maintenance task completion result by the maintenance personnel, the corresponding maintenance task is deleted in the task release block. The specific steps are as follows:

[0041] Establish data transmission link: Establish a stable and secure data transmission link with the internal port of the seismic monitoring station through specific network connection technology and protocols;

[0042] Build OA management module: In the internal port corresponding to the established data transmission link, successfully build the OA management module, which mainly includes two core blocks: task release block and task completion block;

[0043] The task publishing block is used to generate, edit and publish various maintenance tasks, detailing the task content, requirements, execution location, time limit and other key information;

[0044] The task completion block is used to record and display the completion status of maintenance tasks;

[0045] Maintenance task release: The maintenance tasks that have been reasonably planned and arranged will be released through the task release block. These tasks will be accurately pushed to the corresponding maintenance personnel. The maintenance personnel can receive task information through the terminal devices connected to them and understand the specific details of the tasks;

[0046] Maintenance task execution and feedback: Maintenance personnel go to the designated location of the seismic monitoring station to perform maintenance tasks according to task requirements. After completing the maintenance work, the maintenance personnel must promptly feedback the completion results of the maintenance task to the system;

[0047] The management module establishment unit 10 obtains all information of each unmanned station and monitoring equipment through the internal port of the seismic monitoring station, including performance parameters and installation environment.

[0048] The health interval output unit 20 is used to obtain the monitoring data fed back by the monitoring equipment, establish an equipment health assessment model according to the performance parameters and the installation environment, collect historical operation and maintenance records, and then combine the historical operation and maintenance records with the health assessment model to output the health monitoring data interval;

[0049] The health interval output unit 20 includes a model building module and a health interval module;

[0050] The model building module is used to obtain the monitoring data fed back by the monitoring equipment, and divide the monitoring data into historical monitoring data and real-time monitoring data. The real-time monitoring data is the latest feedback monitoring data, and the historical monitoring data is the monitoring data other than the real-time monitoring data. Then, the equipment health assessment model is established based on the performance parameters and the installation environment.

[0051] The health interval module is used to collect historical operation and maintenance records, and then input the historical operation and maintenance records into the health assessment model. After that, the health assessment model outputs the health monitoring data interval of the corresponding monitoring equipment. The specific steps are as follows:

[0052] Extract features closely related to the health status of the equipment from the data. For seismic wave signal data, features such as peak value, mean value, variance, and frequency distribution can be extracted; for equipment working status data, features such as working time and temperature change rate can be extracted. Then, use the feature selection algorithm to select the most representative features for equipment health assessment from the many extracted features and remove redundant or irrelevant features. The formula is as follows:

[0053]

[0054] Among them, H is the health index of the equipment, x b，i is the standardized value of the i-th indicator, w i is the weight of the i-th indicator, and n is the number of evaluation indicators;

[0055] Organize and screen historical operation and maintenance records, extract data related to the evaluation indicators, and process them according to the standardized method when establishing the model. Then substitute them into the health assessment model to calculate the equipment health index corresponding to each historical data point;

[0056] Perform statistical analysis on the calculated historical health index to determine the index distribution range under different health states. Extract the interval without abnormalities based on the statistical results, and determine the extracted interval as the interval of equipment health monitoring data. When the health index exceeds this interval, it indicates that the equipment may be abnormal.

[0057] The maintenance time analysis unit 30 is used to intercept the historical monitoring data after the operation and maintenance, and at the same time perform fluctuation analysis and development trend analysis on the historical monitoring data according to adjacent time periods, and perform maintenance time interval analysis based on the fluctuation analysis results and development trend analysis results combined with the health monitoring data interval;

[0058] The maintenance time analysis unit 30 includes a historical data interception module and a maintenance time analysis module;

[0059] The historical data capture module is used to obtain the time node when the monitoring equipment has completed the latest operation and maintenance task, and then capture the historical monitoring data fed back based on the time node, and classify the historical monitoring data according to the feedback period. The specific steps are as follows:

[0060] Obtain the time node of the operation and maintenance task completion: obtain data from the operation and maintenance management system database of the seismic monitoring station. The database usually records the detailed information of each operation and maintenance task, including the task start time, end time, and equipment involved. Then use the database query statement to obtain the time node of the latest completion of the operation and maintenance task of a specific monitoring device;

[0061] Intercept historical monitoring data: Based on the time node obtained in the previous step, use the database query statement to intercept the historical monitoring data fed back after the time node, and then classify the intercepted historical monitoring data by day.

[0062] The maintenance time analysis module is used to perform fluctuation analysis and development trend analysis on historical monitoring data according to adjacent time periods, and then combine the fluctuation analysis results and development trend analysis results with the health monitoring data interval to perform maintenance time interval analysis. The formula is as follows:

[0063]

[0064] Among them, X c is the mean, x i is the monitoring data value of the i-th day, and n is the total number of days of historical monitoring data after interception;

[0065]

[0066] Among them, S is the standard deviation, which can measure the dispersion of data relative to the mean. The larger the standard deviation, the greater the data fluctuation.

[0067] y=a+bt

[0068]

[0069] a=yc-btc

[0070]

[0071] Among them, t is the time independent variable, y is the monitoring data value, a and b are coefficients, the positive or negative value of coefficient b reflects the development trend of the data, b>0 means the data is on an upward trend, b<0 means the data is on a downward trend, and the absolute value of b reflects the speed of the trend change;

[0072] If the absolute or relative difference of the fluctuation amplitude exceeds a certain threshold and the data point exceeds the health monitoring data interval, it means that the device may be unstable;

[0073] According to the trend obtained by linear regression, if the data in a certain period of time in the future is predicted to exceed the health monitoring data range, maintenance needs to be considered in advance;

[0074] When abnormal fluctuations occur, maintenance should be arranged as soon as possible. The maintenance time interval can be set to the current period plus a buffer period;

[0075] If the trend predicts that the future data will exceed the healthy range, the maintenance time interval should be set to a period before the predicted data exceeds the range;

[0076] Taking into account the results of fluctuation anomalies and trend forecasts, the maintenance time interval is finally determined, and the earlier time of the two is taken to start maintenance.

[0077] The time impact analysis unit 40 is used to obtain the geographical location of the unmanned station and the historical earthquake records, and then perform an impact area analysis based on the historical earthquake records and the geographical location, and then perform an impact index analysis based on the fluctuation analysis results combined with the impact area;

[0078] The time impact analysis unit 40 includes a record acquisition module and an impact index analysis module;

[0079] The record acquisition module is used to obtain the geographical location of each unattended station and obtain historical earthquake records;

[0080] Obtain the geographical location information of each unmanned station from the management system database of the seismic monitoring station;

[0081] Obtain historical earthquake records from earthquake data centers or related databases;

[0082] The impact index analysis module is used to analyze the impact area based on historical geopolitical records and geographical locations, obtain the other unmanned stations affected by the abnormal data of each unmanned station and the degree of impact on other unmanned stations, summarize them into the impact area of ​​each unmanned station, and then combine the fluctuation analysis results with the impact area to perform impact index analysis to generate the impact index of each unmanned station. The specific steps are as follows:

[0083] Calculate the distance: For each unmanned station and each historical earthquake, calculate the distance between the unmanned station and the epicenter;

[0084] Determine the impact range: According to the principles and experience of seismology, the larger the magnitude, the larger the impact range. Establish an impact radius model related to the magnitude.

[0085] Determine the impact relationship: If the distance between the unmanned station and the epicenter is less than or equal to the impact radius of the earthquake, the unmanned station is considered to be affected by the earthquake. For each affected unmanned station, record the degree of its impact;

[0086] Summarize the affected area: For each unmanned station, summarize other unmanned stations affected by it in all historical earthquakes and their degree of influence to form the affected area of ​​the unmanned station.

[0087] Impact index analysis: Review the fluctuation analysis results of historical monitoring data, select appropriate fluctuation indicators, combine the fluctuation analysis results with the impact area, and calculate the impact index of each unattended station. The formula is as follows:

[0088]

[0089] Among them, I index is the influence index of the unmanned station, Lc is the average relative fluctuation amplitude, Q is the impact area, It is the sum of the impact levels of all other unattended stations in the area affected by the unattended station.

[0090] The maintenance task dispatching unit 50 is used to update the maintenance time interval in combination with the impact index, and display the remaining time of each monitoring equipment maintenance task in the OA management module by combining the updated time interval with the real time, and dispatch the maintenance personnel to the maintenance task according to the priority sorting of the remaining time. The specific steps are as follows:

[0091] Determine the impact weight: First, determine the impact weight of the impact index on the maintenance time interval. This value can be determined based on historical data, expert experience, or actual needs. If the impact index is more important for adjusting the maintenance time, its weight can be adjusted higher.

[0092] Calculate the time adjustment amount: Calculate the amount of time that needs to be adjusted based on the impact index and the initial length of the maintenance time interval. The formula is as follows:

[0093] ΔT=w×I index ×T initial

[0094] Among them, ΔT is the time adjustment, w is the weight of the impact index, I index is the impact index, T initial is the length of the initial maintenance time interval;

[0095] Assume that the initial maintenance time interval is [t1, t2], and the length is T initial =t2-t1. If the calculated ΔT is a positive number, it means that the maintenance time interval needs to be extended.

[0096] If ΔT is a negative number, it means that the maintenance time interval needs to be shortened.

[0097] During the maintenance task dispatching process, when the real-time monitoring data of a monitoring device exceeds the health monitoring data interval, the maintenance task dispatching unit 50 will give priority to dispatching the operation maintenance task of the monitoring device;

[0098] At the same time, a fluctuation threshold is set. When the fluctuation analysis result exceeds the fluctuation threshold, the operation and maintenance tasks of the monitoring equipment that exceeds the fluctuation threshold are dispatched first.

[0099] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
