[0002] During the debris flow monitoring process, the monitoring results are based on the monitoring results of the relevant parameters of each monitoring point. Therefore, the richness of the relevant parameters of the monitoring points obtained is likely to have a significant impact on the data processing efficiency and accuracy of the monitoring process. However, the existing debris flow monitoring method only adjusts the monitoring frequency of the overall monitoring points according to whether there is a debris flow risk signal, resulting in poor optimization results for the parameter collection process of the debris flow monitoring process. Therefore, how to optimize the monitoring frequency of the monitoring points in real time according to the actual parameters of different monitoring points to ensure the timeliness of the monitoring results while reducing data redundancy is a problem that needs to be urgently solved by technical personnel in this field.

[0003] Chinese patent application publication number CN116992097A discloses a contact-type debris flow motion parameter monitoring method and system, which relates to the field of debris flow monitoring technology, including: using the comprehensiveness principle to select a group of historical monitoring records as a group of parameter analysis records, sorting them according to the monitoring time sequence to obtain each motion parameter time series data sequence, obtaining the time series linkage between each motion parameter through time series linkage analysis, constructing a motion parameter linkage network through the time series linkage, marking the main nodes of the motion parameter linkage network, using the inclusive principle to select a group of historical monitoring records as a group of point analysis records, reusing each monitoring key parameter time series data sequence in each point analysis record to calculate the accuracy of debris flow warning, and using the motion parameter monitoring point determination model to determine the best monitoring point of the motion parameter.

The data monitoring strategy is to monitor the point data of the geological monitoring point based on the association monitoring strategy, or to monitor the point data of the geological monitoring point based on the reference monitoring strategy; When monitoring is performed based on the associated monitoring strategy, the parameter setting method is determined according to the distribution status of each key monitoring point.

The transmission communication strategy is to adopt a compensation transmission strategy or an auxiliary transmission strategy to transmit the associated transmission data of the data communication node.

[0028] Among them, the present invention is used to monitor and analyze data in areas where debris flow monitoring is required. The target monitoring area is the area where debris flow monitoring is currently required. There are several geological monitoring points in the target monitoring area to obtain point data. The user can set the category of the point data to be obtained according to actual needs. The category of the point data that can be obtained includes but is not limited to soil moisture content and mud level. In addition, there are several data communication nodes in the target monitoring area. Each data communication node needs to complete the uploading of point data of several geological monitoring points. The geological monitoring points that need to complete the uploading of point data of several geological monitoring points are recorded as the associated transmission nodes of the corresponding data communication nodes. Each communication node can transmit point data through different transmission channels. The user can adjust the proportion of wired transmission channels according to the actual working scenario. The point monitoring parameter optimized in the present invention is the number of point data collection times per unit time at each geological monitoring point; The present invention applies several regional monitoring records, and any regional monitoring record records the point interference coefficient, point radiation coefficient, interactive radiation coefficient, data fluctuation range corresponding to the point data, point distribution parameters, radiation key proportion, reference radiation matching index, reference interactive radiation coefficient, monitoring difference coefficient, transmission execution coefficient, environmental interference parameters and mutation duration period in at least one process of debris flow monitoring for the target monitoring area, and each regional monitoring record corresponds to a qualified mark, which records whether the validity of the monitoring data meets the user's needs. It can be understood that the user can determine whether the validity of the monitoring data meets the needs based on self-set indicators. For example, the self-set indicators can be but are not limited to data processing efficiency. The data processing efficiency is the average value of the time taken by the user to determine whether there is an abnormality in each node based on the acquired monitoring data.

[0029] Specifically, when the geological monitoring point is in a critical monitoring state where the point interference coefficient is greater than the preset point interference coefficient or the point radiation coefficient is greater than the preset point radiation coefficient, the point data of the geological monitoring point is monitored based on the associated monitoring strategy. The associated monitoring strategy includes: Determine the parameter setting method according to the distribution status of each key monitoring point; If a key monitoring point is in a limited distribution state, periodically determine whether to adjust the monitoring parameters of the point according to the range mutation cycle index and the reference monitoring mutation index; If a key monitoring point is in a composite distribution state, the division method of the point analysis set of the key monitoring point is determined according to the radiation key ratio, and the point monitoring parameters are adjusted based on the point analysis set.

[0030] Among them, when the key monitoring points are in a limited distribution state, it is determined periodically whether to adjust the point monitoring parameters according to the range mutation cycle index and the reference monitoring mutation index. In the present invention, a cyclic limited reference monitoring cycle is applied, and the duration of the limited reference monitoring cycle can be determined by the user. The duration of a limited reference monitoring cycle is provided, and the limited reference monitoring cycle is 1h. At the end of each limited reference monitoring cycle, it is determined whether to adjust the point monitoring parameters used in the previous limited reference monitoring cycle according to the duration of the mutation and the monitoring mutation index; For a single key monitoring point in a limited distribution state, the monitoring mutation index of each radiation key point within its distribution reference range is periodically detected, and the adjustment necessary coefficient of the key monitoring point is determined according to the range mutation cycle index and the reference monitoring mutation index. The adjustment necessary coefficient = ln (range mutation cycle index × range monitoring mutation index). The range mutation cycle index is the average value of the number of mutation cycles of each radiation key point within the distribution reference range. The range monitoring mutation index is the average value of the monitoring mutation index of each radiation key point within the distribution reference range. For a single radiation key point, the monitoring mutation index is the average value of the absolute value of the difference between the point data of each mutation cycle of the radiation key point. If the adjustment necessary coefficient of the key monitoring point is greater than the preset adjustment necessary coefficient, the point monitoring parameter of the key monitoring point is increased and adjusted, and the increase value of the point monitoring parameter is positively correlated with the adjustment necessary coefficient.

[0031] Specifically, when the geological monitoring point is in a conventional monitoring state where the point interference coefficient is less than or equal to the preset point interference coefficient and the point radiation coefficient is less than or equal to the preset point radiation coefficient, the point data of the geological monitoring point is monitored based on the reference monitoring strategy, and the reference monitoring strategy includes: Periodically determine the point monitoring parameters of each conventional monitoring point based on the point assessment parameters and the risk reference coefficient, and determine whether to adjust the point monitoring parameters of each conventional monitoring point based on the monitoring difference coefficient; The point monitoring parameters are respectively positively correlated with the point assessment parameters and the risk reference coefficient; The conventional monitoring points are geological monitoring points that are in a conventional monitoring state.

[0032] Among them, for a single geological monitoring point, the point interference coefficient = ln (the number of interfering monitoring points of the geological monitoring point × the average value of the interactive radiation coefficients of each interfering monitoring point of the geological monitoring point), the point radiation coefficient = ln (the number of radiation monitoring points of the geological monitoring point × the average value of the interactive radiation coefficients of each radiation monitoring point of the geological monitoring point), for any two geological monitoring points, if the interactive radiation coefficient between the above two geological monitoring points is greater than the preset interactive radiation coefficient, it is determined that there is an interactive radiation relationship between the above two geological monitoring points, and the geological monitoring point with a higher altitude is recorded as the other geological monitoring point. Radiation monitoring points, where a geological monitoring point with a lower altitude is recorded as an interference monitoring point of another geological monitoring point, the interactive radiation coefficient is the product of the number of interfering geological features and the propagation diffusion index, the interfering geological features are the fault area and the joint belt area between the two geological monitoring points, the propagation diffusion index = ln (point slope value / vegetation area), the point slope value is the slope value between the two geological monitoring points, the vegetation area is the area covered by vegetation between the two geological monitoring points, how to determine the fault area, joint belt area, slope value and vegetation area between the geological monitoring points is easy to understand for those skilled in the art, and will not be repeated here; The values ​​of the preset point interference coefficient, the preset point radiation coefficient and the preset interactive radiation coefficient can be determined by the user according to the actual working scenario. For example, the user can set them according to the regional monitoring records. The higher the user's requirements for the validity of the monitoring data, the greater the value of the preset point interference coefficient, the greater the value of the preset point radiation coefficient, and the smaller the value of the preset interactive radiation coefficient. A method for determining the values ​​of the preset point interference coefficient and the preset point radiation coefficient is provided. The minimum value of the point interference coefficient of each key monitoring point in the regional monitoring records that meets the user's requirements for the validity of the monitoring data is recorded as the preset point interference coefficient. The minimum value of the point radiation coefficient of each key monitoring point in the regional monitoring records that meets the user's requirements for the validity of the monitoring data is recorded as the preset point radiation coefficient. A method for determining the value of the preset interactive radiation coefficient is provided. The minimum value of the interactive radiation coefficient between geological monitoring points with interactive radiation relationships in the regional monitoring records that meets the user's requirements for the validity of the monitoring data is recorded as the preset interactive radiation coefficient. The present invention adopts a cyclic reference update cycle, and the duration of the reference update cycle can be determined by the user. A reference update cycle is provided, and the reference update cycle is 12 hours. At the end of each reference update cycle, the point monitoring parameters of each conventional monitoring point are updated according to the point evaluation parameters and the risk reference coefficient, and it is determined whether to adjust the point monitoring parameters of each conventional monitoring point based on the monitoring difference coefficient. For a single conventional monitoring point, a reference update index is determined according to the point evaluation parameters and the risk reference coefficient. The reference update index is the product of the point evaluation parameters and the risk reference coefficient. The point monitoring parameters are positively correlated with the reference update index. The point evaluation parameters are the cumulative sum of the absolute values ​​of the differences between the point data corresponding to each mutation of the monitoring parameters of the conventional monitoring point in the current reference update cycle. The risk reference coefficient is the number of mutation cycles of the geological monitoring points that have an interactive radiation relationship with the conventional monitoring points in the regional monitoring records with the same environmental parameters as those in the current reference update cycle.

[0033] Specifically, the distribution state is determined according to the point distribution parameters of the key monitoring points, and the point distribution parameters are determined according to the number of radiation key points within the distribution reference range and the distribution parameters; If the point distribution parameter of the key monitoring point is greater than the preset point distribution parameter, it is determined that the key monitoring point is in a composite distribution state; If the point distribution parameter of the key monitoring point is less than or equal to the preset point distribution parameter, it is determined that the key monitoring point is in a finite distribution state; The distribution reference range is determined according to the point radiation coefficient of the key monitoring points; The key monitoring points are geological monitoring points that are in a key monitoring state.

[0034] Among them, for a single key monitoring point, the point distribution parameter of the key monitoring point is determined according to the number of radiation key points and distribution parameters within the distribution reference range of the key monitoring point, the point distribution parameter is the product of the number of radiation key points within the distribution reference range and the distribution parameter, the radiation key point is a geological monitoring point in the radiation monitoring points of the key monitoring point that is in a key monitoring state, the distribution parameter is the sum of the radiation reference distance and the radiation reference response time, the radiation reference distance is the average value of the interval distance between each radiation key point and the key monitoring point, the radiation reference response time is the average value of the mutation response time between each radiation key point and the key monitoring point, the distribution reference range of the key monitoring point is a circular area in the horizontal direction with the position of the key monitoring point as the center and the range reference length as the radius, and the range reference length is positively correlated with the point radiation coefficient of the key monitoring point; For any two key monitoring points with an interactive radiation relationship, if a monitoring parameter mutation occurs at one of the interference monitoring points, the interval between the moment when the monitoring parameter mutation occurs at the radiation monitoring point and the moment when the monitoring parameter mutation occurs at the interference monitoring point is detected is recorded as the mutation response duration between the two key monitoring points. For a single geological monitoring point, if the absolute value of the difference between the point data of the geological monitoring point obtained twice in a row is greater than the preset data mutation value, the moment closer to the current moment among the two moments of obtaining the point data is recorded as the moment when the monitoring parameter mutation occurs, and the time range between the two moments of obtaining the point data is recorded as a mutation cycle. The value of the preset data mutation value can be determined by the user according to the actual working scenario. For example, the user can set it according to the regional monitoring record. The higher the user's requirements for the validity of the monitoring data, the smaller the value of the preset data mutation value is. A value of a preset data mutation value is provided, and 5% of the numerical span of the data fluctuation range corresponding to the point data is recorded as the preset data mutation value. The numerical span of the data fluctuation range is the difference between the maximum value of the data fluctuation range and the minimum value of the data fluctuation range. The value of the preset point distribution parameter can be determined by the user according to the actual working scenario. For example, the user can set it according to the regional monitoring record. The higher the user's requirement for the validity of the monitoring data, the smaller the value of the preset point distribution parameter. A method for determining the value of the preset point distribution parameter is provided, and the minimum value of the point distribution parameter of the key monitoring points in the regional monitoring records that meet the user's requirement for the validity of the monitoring data is recorded as the preset point distribution parameter.

[0035] Specifically, when the key monitoring points are in a composite distribution state, the division method of the point analysis set of the key monitoring points is determined according to the radiation key proportion; If the radiation key ratio of the key monitoring point is greater than the preset radiation key ratio, the point analysis set is determined according to the reference radiation matching index of each radiation key point; If the radiation key ratio of the key monitoring point is less than or equal to the preset radiation key ratio, the point analysis set is determined according to the interactive radiation coefficient of each radiation key point.

[0036] Among them, for a single key monitoring point, the radiation key ratio = the number of radiation key points within the distribution reference range of the key monitoring point / the number of key monitoring points within the distribution reference range of the key monitoring point. The value of the preset radiation key ratio can be determined by the user according to the actual working scenario. For example, the user can set it according to the regional monitoring record, and a method for setting the value of the preset radiation key ratio is provided. The regional monitoring record of the point analysis set determined according to the reference radiation matching index of each radiation key point is recorded as the partition reference record, and the minimum value of the radiation key ratio of the key monitoring point in the partition reference record that meets the user's requirements for the validity of the monitoring data is recorded as the preset radiation key ratio; When the radiation key ratio of the key monitoring point is greater than the preset radiation key ratio, it is determined that the reference radiation matching index of each radiation key point in any point analysis set is greater than the preset reference radiation matching index. For the key monitoring point with a single radiation key ratio greater than the preset radiation key ratio, the reference radiation matching index of any radiation key point of the key monitoring point is the number of overlapping mutation cycles between the radiation key point and the key monitoring point; when the radiation key ratio of the key monitoring point is less than or equal to the preset radiation key ratio, it is determined that the reference interaction radiation coefficient of any point analysis set is greater than the preset set radiation coefficient. For the key monitoring point with a single radiation key ratio less than or equal to the preset radiation key ratio, the reference interaction radiation coefficient of the point analysis set of the key monitoring point is the average value of the interaction radiation coefficients between each radiation key point in the point analysis set and the key monitoring point; The values ​​of the preset reference radiation matching index and the preset set radiation coefficient can be determined by the user according to the actual working scenario. For example, the user can set them according to the regional monitoring records. The higher the user's requirements for the validity of the monitoring data, the larger the value of the preset reference radiation matching index and the larger the value of the preset set radiation coefficient. A method for determining the value of the preset reference radiation matching index is provided. The regional monitoring record for determining the point analysis set according to the reference radiation matching index of each radiation key point is recorded as a first partition reference record, and the minimum value of the reference radiation matching index of each radiation key point in the point analysis set in the first partition reference record that meets the user's requirements for the validity of the monitoring data is recorded as the preset reference radiation matching index. A method for determining the value of the preset set radiation coefficient is provided. The regional monitoring record for determining the point analysis set according to the interactive radiation coefficient of each radiation key point is recorded as a second partition reference record, and the minimum value of the reference interactive radiation coefficient of each point analysis set in the second partition reference record that meets the user's requirements for the validity of the monitoring data is recorded as the preset reference interactive radiation coefficient.

[0037] Specifically, the data change trend overlap and mutation duration of each radiation key point in the point analysis set of the key monitoring points in the composite distribution state are periodically detected, and the point monitoring parameters are increased and adjusted according to the reference trend overlap and mutation duration; The increase value of the point monitoring parameter is positively correlated with the overlap degree of the reference trend and the duration of the mutation.

[0038] Among them, the present invention applies a cyclic composite reference monitoring cycle, the duration of the composite reference monitoring cycle can be determined by the user, and a composite reference monitoring cycle is provided. The composite reference monitoring cycle is 15 minutes. At the end of each composite reference monitoring cycle, the point monitoring parameters are adjusted according to the overlap of data change trends and the duration of mutations. For any key monitoring point that has completed the division of the point analysis set, the overlap of data change trends and the duration of mutations of each radiation key point in the point analysis set of the key monitoring point are detected, and the composite reference coefficient is determined according to the reference trend overlap and the reference mutation duration. The composite reference Coefficient = ln (reference trend overlap × reference mutation duration), reference trend overlap is the average value of the data change trend overlap of each radiation key point in the point analysis set, reference mutation duration is the maximum value of the mutation duration of each radiation key point in the point analysis set, for any radiation key point in the point analysis set of the key monitoring point, the mutation duration is the time between the moment when the monitoring parameter mutation of the radiation key point first occurs in the current composite reference monitoring cycle and the current moment, data change trend overlap = the overlap of the radiation key point with the key trend of the key monitoring node in the current composite reference monitoring cycle. The duration of the similar stage / the duration of the composite reference monitoring cycle, the end time of each composite reference monitoring cycle, generate a data change trend curve based on the point data obtained each time in the corresponding composite reference monitoring cycle, and divide the data change trend curve into several stage curves. The duration corresponding to each stage curve is the same. If the change trend difference coefficient of a set of several continuous stage curves between a radiation key point and the key monitoring point is less than the preset change trend difference coefficient, then the above several continuous stage curve sets are recorded as key trend similar stages. For a single key trend similar stage, the change trend difference coefficient of the set of corresponding two stage curves = ln (similar stage curve proportion / overall change difference value), the similar stage curve proportion = the number of similar stage curves / the number of stage curves contained in the similar stage of the key trend. If the absolute value of the difference in the data change values ​​between two stage curves is less than the preset stage curve difference value, the two stage curves are determined to be similar stage curves to each other. The data change value is the difference between the point value corresponding to the end point of the stage curve and the point value corresponding to the starting point.
