Description

Technical Field

[0001] The present invention relates to the technical field of waterway maintenance, and in particular to a method and system for optimizing a waterway routine maintenance plan based on multi-source data. Background Art

[0002] As an important channel for water transportation, waterways play a key role in regional economic development and regional connectivity. However, some waterways have problems such as siltation, narrowness, shallowness, and curvature, which affect navigation capacity and navigation safety. Therefore, waterway maintenance is of great significance to improving waterway navigation conditions and promoting the development of water transportation.

[0003] In recent years, with the rapid development of digital technology and data analysis technology, the requirements for scientificity and efficiency of waterway maintenance have been continuously improved; however, the contradiction between the traditional management methods currently used by waterway management departments in actual work and the growing demand for high-quality maintenance has become increasingly prominent; therefore, it is necessary to start from the source, formulate accurate waterway maintenance plans, and promote efficient and scientific maintenance work.

[0004] The data types of waterway maintenance management are rich, and the amount of data continues to increase. However, it is difficult to collect and fully apply the existing large amount of historical data. At the same time, the traditional routine maintenance plan formulation often follows the historical plan, lacks the scientific nature of customization, and has a certain impact on the effect of specific maintenance implementation. Specifically:

[0005] (1) Incomplete data collection: Waterway maintenance management involves various data including policies and regulations, process systems, waterway evolution, maintenance implementation, hydrological and meteorological data. The data types are rich and the data volume is large, but the current management department cannot effectively collect and manage these data;

[0006] (2) Insufficient in-depth analysis: Waterway maintenance management involves a lot of complex data, including time, cost, quality, safety, resources and other dimensions; however, traditional management methods do not fully integrate and deeply analyze these data to support the scientific formulation of waterway maintenance plans;

[0007] (3) The plan presentation is not intuitive: The waterway maintenance plan involves many aspects. Traditionally, it is presented in text form, which makes it impossible to intuitively understand the geographical characteristics of the maintained waterway and the overall characteristics of the maintenance plan, and it is also impossible to effectively identify and compare the differences between different maintenance plans. Summary of the invention

[0008] In response to the above problems, an object of the present invention is to provide a method for optimizing routine waterway maintenance plans based on multi-source data. The method analyzes the existing routine waterway maintenance plans and gives optimization suggestions through the collection, processing, integration and multi-dimensional analysis of multi-source waterway management data, and presents the routine waterway maintenance plans in a multi-dimensional manner, thereby effectively solving the problem that the current routine waterway maintenance plans are relatively subjective based on experience and relatively general in text presentation.

[0077] The quality of the waterway basic data is examined from the perspectives of "standardization, completeness, accuracy, consistency, timeliness and accessibility". After cleaning the waterway basic data, it is marked and displayed on the map according to the waterway grade, building category, etc., to construct a spatial geographic database and attribute database of the waterway basic data.

[0078] (3) Historical waterway routine maintenance implementation data;

[0079] The historical waterway routine maintenance implementation data includes one or more of historical navigation mark maintenance, waterway inspection implementation data, historical waterway maintenance dredging implementation data, and historical waterway maintenance observation implementation data;

[0080] Among them, the waterway routine maintenance implementation system is connected to obtain historical navigation mark maintenance and waterway patrol implementation data; historical navigation mark maintenance and waterway patrol implementation data specifically include navigation mark maintenance, waterway patrol records, waterway patrol problems, work organization plans, technical plans, patrol problems, abnormal solution records, etc.;

The cleaned historical waterway water level and flow data obtained from external departments are merged with the historical waterway level and flow data obtained from the hydrological telemetry device of the waterway management department according to time, location and other identifiers to obtain historical waterway water level and flow data. A historical waterway water level and flow database is constructed based on historical waterway water level and flow data.

[0088] S200: Develop routine waterway maintenance plans based on the waterway maintenance plan development requirements;

[0089] According to the requirements for formulating the waterway maintenance plan, the content of the requirements is logically extracted, refined and structured to form a routine waterway maintenance plan; the routine waterway maintenance plan includes various routine maintenance plan contents such as navigation mark maintenance and waterway inspection work plan, waterway maintenance dredging work plan, and waterway maintenance observation work plan.

[0090] Furthermore, in one embodiment, it also includes judging the integrity of the contents of the routine waterway maintenance plan according to the contents of the routine waterway maintenance plan, according to the categories of the routine waterway maintenance plan and the sections involved in the management area, so as to ensure the integrity of the contents of the routine waterway maintenance plan.

[0091] The integrity assessment of the contents of the routine waterway maintenance plan includes:

[0092] For the navigation mark maintenance and waterway inspection work plan, determine whether the number of maintenance marks and the number of maintenance project days are complete;

[0093] For the waterway maintenance dredging work plan, determine whether the dredging location, engineering quantity, and implementation schedule are complete;

[0095] The present invention analyzes the actual needs of waterway maintenance according to the waterway maintenance management regulations of the waterway maintenance management department, sorts out the contents of the waterway routine maintenance plan, determines the data type, scope and relationship, and plans the data storage strategy at the same time, constructs various types of waterway routine maintenance plan databases, and confirms the integrity of the formulated waterway routine maintenance plan, thereby ensuring the integrity of the formulated waterway routine maintenance plan and making it more convenient to optimize and manage the waterway routine maintenance plan.

[0096] S300: Optimizing the waterway routine maintenance plan based on the multi-source data;

[0097] The formulated routine waterway maintenance plan is comprehensively analyzed and evaluated based on multi-source data, and optimization suggestions are provided from the target dimension and execution dimension. The plan preparation personnel modify the plan according to the modification suggestions and reasons and complete the plan formulation; based on the pre-processed multi-source data, the routine waterway maintenance plan is optimized, including the optimization of navigation mark maintenance and waterway inspection work plans, the optimization of waterway maintenance dredging work plans, and the optimization of waterway maintenance observation work plans.

[0098] (1) Optimize the navigation mark maintenance and waterway inspection work plan;

[0099] like Figure 2As shown, in combination with the relevant standards and specifications for routine waterway maintenance and historical navigation mark maintenance and waterway inspection records, the navigation mark maintenance and waterway inspection work plan is optimized and analyzed, including the following sub-steps:

[0100] S311: Obtaining the standard value of the inspection cycle and inspection frequency of the flight segment based on multi-source data;

[0101] Based on parameters such as the maintenance channel grade and maintenance level in the relevant standards and specifications for routine channel maintenance, the standard values ​​of the section inspection cycle and inspection frequency are obtained. Local standards and specifications and management regulations will have obvious standard values ​​of the section inspection cycle and inspection frequency, which are different in different places.

[0102] S312: obtaining an actual patrol cycle and a median patrol frequency based on multi-source data; and obtaining a patrol weight value for each flight segment based on the standard patrol cycle and patrol frequency of the flight segment and the median patrol cycle and patrol frequency;

[0103] Based on the historical navigation mark maintenance and waterway inspection records in the multi-source data, the actual inspection cycle and the median inspection frequency are analyzed, including: according to the actual inspection cycle and frequency data, the actual inspection cycle and frequency data are arranged from small to large. If the number of actual inspection cycle and frequency data is an odd number, the middle number is the median of the actual inspection cycle and inspection frequency; if the number of actual inspection cycle and frequency data is an even number, the average of the two middle values ​​is taken as the median of the actual inspection cycle and inspection frequency.

[0104] The actual inspection period and the median of the inspection frequency are compared with the standard inspection period and inspection frequency, and the inspection weight of each flight segment is assigned to obtain the inspection weight value of each flight segment. That is, the inspection weight value of each flight segment is expressed by the following formula:

[0105] The weight value of the flight segment inspection = the median of the actual inspection period and inspection frequency / the standard value of the flight segment inspection period and inspection frequency.

[0106] S313: adjusting the inspection weight value of each route segment based on the waterway inspection record to obtain a final inspection weight value of each route segment;

[0107] Problems existing in the waterway inspection records are classified and analyzed by flight segments to clarify the type, severity, and cause (natural cause, man-made damage) of the problems; the inspection weight of the flight segment whose frequency of man-made damage exceeds the set threshold (the set threshold is set by the management personnel, and the threshold is different for different flight segments) in the flight segment inspection weight value obtained in step S312 is increased (the weight increase value is set by the management personnel, and the increase ratio is different for different flight segments) to obtain the final inspection weight value of each flight segment; that is, the inspection weight of the flight segment whose frequency of man-made damage exceeds the set threshold in the flight segment inspection weight value is increased to obtain the final inspection weight value of each flight segment.

[0108] S314: Based on the final inspection weight value of each flight segment, the inspection cycle and inspection frequency of each flight segment are calculated to obtain the inspection cycle and inspection frequency calculation value of each flight segment; determine whether the inspection cycle and inspection frequency calculation value of each flight segment are consistent with the planned value, and if not, give optimization suggestions according to the inspection cycle and inspection frequency calculation value of each flight segment;

[0109] Based on the final inspection weight value of each segment, the inspection cycle and inspection frequency of each segment are calculated in combination with the actual inspection cycle and the median of the inspection frequency, and the calculated value of the inspection cycle and inspection frequency of each segment is obtained; it is determined whether the calculated value of the inspection cycle and inspection frequency of each segment is consistent with the planned value of the inspection cycle and inspection frequency of each segment in the navigation mark maintenance and waterway inspection work plan. If not, optimization suggestions are given according to the calculated value of the inspection cycle and inspection frequency of each segment, that is, the recommended inspection cycle and inspection frequency are proposed, and the reasons are explained; if consistent, there is no need to modify the inspection cycle and inspection frequency of each segment in the navigation mark maintenance and waterway inspection work plan.

[0110] S315: Modify the navigation mark maintenance and waterway inspection work plan based on the optimization suggestion to form an optimized navigation mark maintenance and waterway inspection work plan.

[0111] The planners completed the optimization and modification of the navigation mark maintenance and waterway inspection work plan according to the optimization suggestions, and formed an optimized navigation mark maintenance and waterway inspection work plan.

[0112] (2) Optimize the waterway maintenance and dredging work plan;

[0113] like Figure 3 As shown, combined with historical navigation mark maintenance, channel inspection records, historical channel maintenance and dredging implementation data, channel water level and water flow data over the years, the channel maintenance and dredging work plan is optimized and analyzed, including:

[0114] S321: Calculate the matching degree between the section to be dredged and the planned dredging section in the waterway maintenance dredging work plan;

[0115] The waterway maintenance and dredging work plan is marked on the electronic map according to the sections; and the waterway inspection records are extracted to mark the area to be dredged on the electronic map, and it is determined whether the planned dredging section in the waterway maintenance and dredging work plan covers the section to be dredged (i.e. the problem section), that is, the matching degree between the section to be dredged and the planned dredging section in the waterway maintenance and dredging work plan is calculated. The higher the overlap between the planned dredging section in the waterway maintenance and dredging work plan and the section to be dredged (i.e. the problem section) on the map, the higher the matching degree.

[0116] S322: Calculate the deviation between the planned dredging workload per unit time and the historical dredging workload per unit time;

[0117] Extract historical waterway maintenance dredging implementation data, calculate the dredging volume generated per unit time according to each dredging work, and fit to form a historical dredging volume change curve generated per unit time, which includes the maximum and minimum values ​​of the historical dredging workload per unit time; judge whether the planned dredging workload per unit time in the current waterway maintenance dredging work plan is greater than the maximum value of the historical dredging workload per unit time. If it is greater than the maximum value of the historical dredging workload per unit time, it means that there is a significant deviation between the planned dredging workload per unit time and the historical dredging workload per unit time, calculate the difference between the planned dredging workload per unit time and the maximum value of the historical dredging workload per unit time, and obtain the deviation degree between the planned dredging workload per unit time and the historical dredging workload per unit time;

[0118] Alternatively, it is determined whether the planned dredging workload per unit time in the current waterway maintenance and dredging work plan is less than the minimum value of the historical dredging workload per unit time. If it is less than the minimum value of the historical dredging workload per unit time, it means that there is a significant deviation between the planned dredging workload per unit time and the historical dredging workload per unit time. The difference between the planned dredging workload per unit time and the minimum value of the historical dredging workload per unit time is calculated to obtain the degree of deviation between the planned dredging workload per unit time and the historical dredging workload per unit time.

[0119] S323: Based on the multi-source data, a time period when the water level and water flow change rate are greater than a set threshold is obtained, and whether the planned construction time is within the time period when the water level and water flow change rate are greater than the set threshold is determined; if it is within the time period, a construction time optimization suggestion is given;

[0120] Extract the water level and flow data of the waterway over the years and draw a water level-flow time series diagram; and analyze the water level and flow change rate based on the water level-flow time series diagram to identify the time period when the water level and flow change rate exceeds the set threshold (the set threshold is set by business personnel according to the conditions of the specific section, and the value is different for different waterways), that is, the time period with a large water level and flow change rate;

[0121] Determine whether the planned construction time in the waterway maintenance and dredging work plan is within the time period with large water level and water flow change rates mentioned above; if the planned construction time is within the time period with large water level and water flow change rates mentioned above, give suggestions for optimizing the construction time.

[0122] S324: Obtaining a comprehensive optimization suggestion based on the matching degree, deviation degree, and construction time optimization suggestion;

[0123] Based on the matching degree between the sections to be dredged and the planned dredging sections in the waterway maintenance dredging work plan (i.e. the planned dredging section coverage rate), specific suggestions on changes in dredging section coverage are put forward; based on the deviation between the planned dredging workload per unit time and the historical dredging workload per unit time, suggestions on deviation in dredging workload (too much or too little) and suggestions on construction time optimization (i.e. suggestions on the need to adjust the dredging plan construction time) are put forward to obtain comprehensive optimization suggestions.

[0124] S325: Modify the waterway maintenance and dredging work plan based on the comprehensive optimization suggestion to form an optimized waterway maintenance and dredging work plan.

[0125] The planners completed the optimization and modification of the waterway maintenance and dredging work plan according to the comprehensive optimization suggestions and formed an optimized waterway maintenance and dredging work plan.

[0126] (3) Optimize the waterway maintenance observation work plan;

[0127] like Figure 4 As shown in the figure, combined with the relevant standards and specifications for routine waterway maintenance and historical waterway maintenance observation implementation data, the waterway maintenance observation work plan is optimized and analyzed, including:

[0128] S331: Obtain the standard value of the maintenance observation frequency of the waterway to be maintained;

[0129] Based on parameters such as waterway grade and waterway maintenance level in relevant standards and specifications for routine waterway maintenance, the standard values ​​of maintenance observation frequency for the waterway to be maintained are analyzed.

[0130] S332: Based on the historical waterway maintenance observation implementation data, obtain the time period and average number of observations when the observation frequency is higher than the standard value or lower than the standard value every year;

[0131] Based on the historical waterway maintenance observation implementation data, the time series of the number of observations per year was fitted, and the multi-year time series were superimposed and represented by a scatter plot. The periodicity of the observation frequency changing with the month was analyzed, and the time sections and the average number of observations when the observation frequency was higher than the standard value throughout the year, and the time sections and the average number of observations when the observation frequency was lower than the standard value throughout the year were obtained, that is, the average number of observations in special time periods.

[0132] S333: judging whether the planned observation frequency is less than the standard value of the observation frequency for the waterway to be maintained, and if so, giving suggestions for optimizing the observation frequency; and judging whether the planned observation times in the special time period are the same as the planned observation times in other normal time periods, and if so, giving suggestions for optimizing the observation times according to the average observation times in the special time period;

[0133] Based on the standard value of maintenance observation frequency for waterways to be maintained and the average number of observations in special time periods, an analysis is conducted to determine whether the planned observation frequency in the waterway maintenance observation work plan is greater than or equal to the standard value of maintenance observation frequency for waterways to be maintained. If the planned observation frequency is greater than or equal to the standard value of maintenance observation frequency for waterways to be maintained, it is considered that the planned observation frequency meets the standard value of maintenance observation frequency for waterways to be maintained; if the planned observation frequency is less than the standard value of maintenance observation frequency for waterways to be maintained, it is considered that the planned observation frequency does not meet the standard value of maintenance observation frequency for waterways to be maintained.

[0134] And determine whether the planned number of observations in a special time period in the waterway maintenance observation work plan is the same as the planned number of observations in other normal time periods. If they are the same, optimization suggestions for the number of observations are given based on the average number of observations in the special time period.
