Technical Field

[0001] The present invention relates to the technical field of marine emergency management, and in particular to a marine emergency command and dispatch method and system based on data processing. Background Art

[0002] The field of marine emergency management technology includes the comprehensive management of the response, control and recovery process of marine emergencies. This technical field focuses on effectively responding to various emergencies such as marine oil spills, ship collisions, and marine search and rescue through various management measures and technical means. The core content of marine emergency management includes event warning, emergency response, resource scheduling and command and coordination, aiming to minimize the impact of accidents on the marine environment and human activities. This technical field requires the comprehensive use of multidisciplinary knowledge such as information technology, communication technology and management to build a system that can quickly respond to and effectively handle marine emergencies.

[0003] Among them, the marine emergency command and dispatch method of data processing refers to the process of using data processing technology to optimize marine emergency response and resource allocation, which mainly involves collecting data information of relevant sea areas, using data analysis and processing technology to conduct real-time assessment of the situation, and making command decisions accordingly. The technical matters covered include data collection, processing and analysis, as well as decision-making information based on the analysis results, mainly through computer systems and software to achieve rapid data processing and generation of response instructions, and improve the efficiency and accuracy of marine emergency command and dispatch.

[0004] Although existing technologies in maritime emergency management cover incident warning and emergency response, there are limitations in data processing speed and efficiency in actual operation. Conventional technologies cannot perform real-time data analysis and processing of maritime emergencies, resulting in delayed response. This delay increases the risk to the environment and personnel safety in emergency situations. The accuracy and timeliness of resource scheduling are insufficient, and resource allocation is not timely and does not meet actual needs due to the lack of an effective data support system. For activities such as offshore oil pollution treatment or maritime search and rescue, if resource allocation is delayed or inaccurate, it will cause pollution to spread or search and rescue opportunities to be lost, affecting the effectiveness and efficiency of emergency response.

[0064] See also Figure 2 , collect data streams from offshore monitoring stations and weather stations, integrate the collected wind speed, wave height and ship position information, identify data points that do not conform to the normal pattern, analyze the data points, and determine whether they are abnormal events. The specific steps to obtain the ocean data set are:

[0065] S101: Collect data streams from offshore monitoring stations and weather stations, including wind speed, wave height and ship position information, transmit them in real time through the communication network, and update the data in real time to obtain the original data set. The execution process is as follows;

[0066] Data from offshore monitoring stations and meteorological stations, including wind speed, wave height, ship location and other information, are collected and transmitted in real time through high-frequency communication networks. Encryption technology is used during data transmission to ensure information security. At the same time, data collectors deployed at each node of the network preliminarily screen the information and remove data points with obvious errors, such as abnormal data where the wave height suddenly jumps from 2 meters to 20 meters. This data is caused by sensor failure or data transmission error. In this way, preliminary quality control can be performed before the data reaches the server to ensure that the incoming data has a certain degree of reliability. The data set received by the server is the original data set. This efficient data processing mechanism ensures the timeliness and accuracy of monitoring data, providing a reliable data basis for maritime safety and climate research. This process is crucial for subsequent data analysis and decision-making, because only high-quality data can ensure the accuracy of analysis results and the effectiveness of application, and obtain the original data set.

[0067] S102: Extract key information from the original data set, identify data points that deviate from the normal range, analyze abnormal fluctuations and trends that do not conform to the normal pattern, and obtain the execution process of the deviation analysis results as follows;

[0068] Extract key information from the original data set and identify data points that deviate from the normal range according to the formula:

[0069]

[0070] In the formula, σ represents the standard deviation, x c represents each data point, μ represents the average value of data point c, and Z represents the total number of data points;

[0071] Calculate the mean μ of the data points, which is obtained by summing all data points and dividing by the number of data points N;

[0072] Set the data points of wind speed to 10, 12, 9, 11, 10 m / s, then μ = (10 + 12 + 9 + 11 + 10) / 5 = 10.4 m / s;

[0073] Sum the squares of the differences between each data point and the mean, and divide by the number of data points Z to get the variance;

[0074] Taking the square root of the variance gives the standard deviation σ. This step is used to identify data points that deviate too much from the mean. Wave heights or wind speeds that exceed twice the standard deviation are considered abnormal. This statistical analysis method is very suitable for anomaly detection in a big data environment, with high reliability and ease of real-time monitoring and early warning.

[0075] S103: Based on the deviation analysis results, the influencing factors of the data point deviation are evaluated, including weather changes, abnormal ocean currents and human activities, and the execution process of the ocean data set is as follows;

[0076] Evaluate the influencing factors of data point deviations, including weather changes, abnormal ocean currents, human activities, etc., and conduct in-depth correlation analysis of factors through data mining technology. For example, use decision tree algorithms to classify influencing factors, and find out the interactions between different factors through association rule mining, which can help determine the main driving factors of specific deviations. For example, it is found that the abnormal ocean current speed in a specific area is related to the excessive concentration of nearby ships. Through analysis, it can provide data support for marine management departments, help formulate policies and response measures more effectively, better manage and protect marine resources, and provide important references for subsequent research. This process not only improves the application value of data, but also enhances the adaptability and response speed to changes in the marine environment, laying a solid foundation for marine scientific research and practical applications, and obtaining marine data sets.

[0077] See also Figure 3 , perform time series analysis on the ocean data set, perform data processing, calculate standard deviation and mean, identify abnormal fluctuations in the data, identify the type of event, including sudden ocean storms and sudden changes in ship speed, and set corresponding alarm levels. The specific steps to obtain key event detection results are as follows:

[0078] S201: Perform time series analysis on the ocean data set, extract data points to form a continuous timeline, perform data fluctuation analysis, arrange the data in chronological order, and mark the timestamps of the data points. The execution process of obtaining time-stamped data is as follows;

[0079] When processing ocean data sets, time series analysis is performed, which is done by extracting data points and forming a continuous timeline. This process involves arranging the data points in the order of their occurrence and marking each data point with a timestamp. The key to this step is to ensure the timing and integrity of the data to facilitate subsequent analysis of fluctuations and trends. Data fluctuation analysis relies on such time-stamped data, through which changes in ocean environmental parameters such as temperature, salinity, wave height, etc. over time can be observed. The timestamps of marked data points are the basis for analyzing how data changes over time, allowing researchers to track the specific time of occurrence of each data point, analyze the periodicity and anomalies of data fluctuations, and obtain time-stamped data.

[0080] S202: Based on the time-stamped data, the standard deviation and mean of the data points are calculated, and by comparing the deviation between the real-time value of the data point and the statistical mean, the data points with fluctuations beyond the normal range are identified, and the data peaks and abnormal reductions are captured. The execution process of obtaining the abnormal fluctuation data points is as follows;

[0081] Calculating the standard deviation and mean of data points is a common step in statistical analysis. By calculating statistics, the degree of deviation of the real-time value of the data point from the statistical mean can be compared. This analysis helps identify data points that fluctuate beyond the normal range, that is, points that appear as data peaks or abnormal decreases. Identifying abnormal data points is the key to understanding and dealing with potential problems in marine data sets. It can reveal signals of potential environmental changes or equipment failures. It involves complex data processing techniques, such as moving averages or exponential smoothing, which help smooth time series data and more clearly identify true outliers, resulting in abnormally fluctuating data points.

[0082] S203: Using abnormal fluctuation data points, identify the event types of sudden ocean storms and ship speed changes, calculate the abnormal score value based on the fluctuation characteristics and fluctuation trends of the abnormal data points, and set the corresponding event alarm level. The execution process of obtaining the key event detection results is as follows;

[0083] The formula for calculating the anomaly score value is:

[0084]

[0085] Among them, A t represents the abnormal score value at time t, D t-1 , D t-2 and D t-3represent the marine environment monitoring data points at time t-1, t-2 and t-3 respectively, w1, w2 and w3 are weight coefficients;

[0086] Parameter meaning and setting value:

[0087] A t is the abnormal score value at time t, indicating the probability of emergencies in the marine environment;

[0088] D t-1 ,D t-2 ,D t-3 For monitoring data at three consecutive time points, such as wind speed or wave height, the monitoring data is collected directly from ocean sensors. Set D t-1 =15m / s, D t-2 =17m / s, D t-3 =13m / s;

[0089] w1, w2 and w3 are weight coefficients, which are determined based on the correlation analysis of historical data. Let w1 = 0.5, w2 = 0.3, w3 = 0.2, which reflects D t-1 A t The impact of is the greatest, and as time goes by, the impact of the data point gradually decreases;

[0090] Substitute the parameters into the formula for calculation:

[0091]

[0092] The results show that the environmental status at the current time t has higher abnormal activity relative to the previous three data points. Based on this score value, an early warning can be issued and appropriate response measures can be activated to ensure maritime safety.

[0093] See also Figure 4 ,Using the key event detection results, we conduct a matching analysis between real-time resources and marine emergency needs. By evaluating the spatial and temporal relationship between the location and status of resources and emergency events, the steps to obtain the resource allocation plan are as follows:

[0094] S301: Using the key event detection results, extract the key event information, including the type, time and location of the event, and perform an initial resource matching demand analysis to obtain the event and resource matching record. The execution process is as follows;

[0095] Extract information about key events, including determining the type, time and location of the event. Through the information, perform an initial resource matching demand analysis. This process uses advanced data analysis technology to classify and label event information. The system compares event characteristics with resource records in the database and selects qualified rescue units and equipment, such as maritime rescue ships, helicopters and medical equipment. The matching process takes into account the availability, response time and geographical location of each resource to ensure that the selected resources best match the needs of the event. After a successful match, the allocation of each resource and the estimated investment time are listed in detail. As part of the response plan, it is crucial to respond quickly and effectively to emergencies at sea, ensure the optimal allocation of resources and rapid response, and obtain event and resource matching records.

[0096] S302: Through the event and resource matching records, the location and status of available marine emergency resources are evaluated, including the real-time location and response status of rescue vessels, helicopters and rescue equipment, and compared with the event location and time in the event and resource matching records, and the arrival time of resources and the urgency of the event are analyzed to obtain the execution process of the resource allocation analysis results as follows;

[0097] Assess the location and status of available marine emergency resources according to the formula:

[0098]

[0099] In the formula, J arrival represents the resource arrival time, J event represents the time when the event occurs, S represents the distance of the resource from the event location, and V represents the speed of resource movement;

[0100] Get the event occurrence time from the event and resource matching record event and the current location of the resource. Assume that a rescue ship is located 100 km north of the incident site, and the average moving speed of the ship is 30 km / h. The incident time is 08:00. Then the distance between the resource and the incident site is D = 100 km, and the moving speed of the resource is V = 30 km / h.

[0101] Substitute the values ​​into the formula to calculate:

[0102]

[0103] This calculation method provides scientific time estimates for emergency response, ensuring that resources can arrive at the scene in the shortest possible time.

[0104] S303: According to the resource allocation analysis results, referring to the real-time dispatch probability of multiple types of resources and the response efficiency to emergency events, marine emergency manpower mobilization and resource dispatch are carried out, and the execution process of the resource allocation plan is obtained as follows;

[0105] The system evaluates the scheduling priority of various resources, the availability of human resources and skill matching. It predicts the response efficiency of different resource combinations through algorithm models and selects the optimal plan for scheduling, including how to choose helicopters or rescue ships for initial rapid response, while considering the mobilization of subsequent medical and technical support teams. Decisions are based on complex algorithms and historical data analysis to ensure that a quick and accurate response can be made in the face of multiple estimated emergency situations. The specific scheduling time and location of various resources are specified in detail, providing a detailed execution blueprint for actual operations, which not only improves rescue efficiency, but also significantly reduces potential risks and costs.

[0106] See also Figure 5 According to the resource allocation scheme, the differentiated marine emergency response situations are simulated, the efficiency and response time of the resource allocation scheme are evaluated, the performance is compared, and the command and dispatch of marine emergency are optimized. The specific steps to obtain the response efficiency analysis results are as follows:

[0107] S401: Based on the resource allocation scheme, differentiated marine emergency response simulation scenarios are constructed, differentiated resources are allocated to each scenario, and responses are performed when simulating target type marine emergency events. The execution process of the simulated response situation is as follows;

[0108] Carry out differentiated marine emergency response simulations. This process involves building multiple simulation scenarios, each of which allocates corresponding resources according to its specific needs. The simulation scenarios are designed to simulate different types of marine emergencies, such as ship sinking, offshore oil spills, or natural disasters. Through simulation, the actual effect of various resource allocations on emergency response can be tested and evaluated. During the simulation, the deployment of various resources such as rescue ships, helicopters, and rescue equipment are carried out according to the preset plan, while recording the response time and processing efficiency. The data will be used to evaluate the effectiveness of the simulation and provide a basis for improvement of the actual emergency response, which will help identify the strengths and weaknesses of resource allocation, make necessary adjustments and optimizations, and obtain simulated response situations.

[0109] S402: By simulating response situations, evaluating response time and efficiency in differentiated scenarios, calculating weighted average response time, identifying key factors causing response delays, and obtaining performance comparison results, the execution process is as follows;

[0110] The formula for calculating the weighted average response time is:

[0111]

[0112] Among them, BR is the weighted average response time, N represents the number of simulations, and x i represents the randomly generated scene parameters in the i-th simulation, f(x i) is the response time of the scenario, T represents the operation time, k represents the adjustment coefficient, a and b represent the key parameters of the resource allocation scheme, and e is the base of the natural logarithm;

[0113] Parameter meaning and setting value:

[0114] N is the number of simulations, and the operation frequency within one year is obtained from the data monitoring system and is set to 10000, reflecting the frequency of the operation;

[0115] x i The randomly generated scenario parameters come from the actual operation data set and reflect different operation environments;

[0116] f(x i ) is the response time for a specific scenario, which is established based on historical performance data;

[0117] T is the operation time, the average operation time from the system log, and the set value is 300 seconds, indicating the duration of the operation;

[0118] k is the adjustment coefficient, which is set to 0.05 based on the system adjustment history of the past year, expressing the sensitivity of time extension to system performance;

[0119] a and b are key parameters of the resource configuration scheme, which are obtained from the system configuration log. a is 500GB and b is 450GB, showing the storage capacity of different resource configurations.

[0120] Substitute the parameters into the formula for calculation:

[0121] Calculate |ab|, the result is 50GB, the square root is about 7.07, and the reciprocal is about 0.141;

[0122] Calculate e using e k×T , given k = 0.05 and T = 300, the result is about 164;

[0123] set up To simulate the total response time, set the value to 2000000 milliseconds and substitute it into the formula:

[0127] Adjust and optimize the marine emergency command and dispatch, which includes reconfiguring resources to avoid unnecessary response time and improve the overall efficiency of marine emergency handling. During the adjustment process, not only the quantity and type of resources are considered, but also the optimization of dispatch orders, the rearrangement of personnel layout, and the optimal deployment of rescue equipment. Through optimization measures, it is aimed to reduce the start-up time of rescue operations, improve rescue efficiency, and ensure that when facing actual marine emergencies, a quick and effective response can be carried out, which will directly affect the handling strategy and success rate of future marine emergency events, and obtain the response efficiency analysis results.

[0128] See also Figure 6 , using the response efficiency analysis results, conduct marine emergency command and dispatch and real-time resource adjustment, adjust the priority of task allocation and resource utilization efficiency, respond to the rescue needs of risk areas, and obtain the specific steps of marine emergency command and dispatch instructions:

[0129] S501: Based on the response efficiency analysis results, evaluate and adjust the use of multiple resources and task allocation in marine emergency response, analyze efficiency bottlenecks and time delays, optimize task priorities, and obtain the execution process of priority ranking records as follows;

[0130] Evaluate and adjust the use of multiple resources and task allocation in marine emergency response. This process involves in-depth analysis of the utilization efficiency of existing resources, identifying efficiency bottlenecks and the main causes of time delays, such as unreasonable routes of rescue ships, insufficient rescue personnel or outdated rescue equipment. In response to the problems, re-optimize the priority of tasks, use advanced algorithm models for simulation and prediction, ensure that the most urgent and most influential events are handled first, and list the priority of each rescue task in detail. The priority is determined based on the urgency of the task, the scope of impact and the status of available resources, ensuring that limited resources can be used most effectively in a changing marine environment. This not only improves rescue efficiency, but also significantly reduces estimated losses and risks, and obtains priority ranking records.

[0131] S502: Using the priority sorting records, real-time monitoring of marine emergency command and dispatch, including dispatch of ships, rescue personnel and rescue equipment, and allocation of resources according to the real-time marine conditions and changes in risk areas, the execution process of obtaining real-time resource adjustment records is as follows;

[0132] Real-time monitoring of marine emergency command and dispatch, including the dispatch of ships, rescue personnel and rescue equipment. During this process, the command center uses the latest communication technology and geographic information systems to dynamically allocate resources according to real-time marine conditions and changes in risk areas. For example, after receiving a new marine incident report, it quickly adjusts the deployment of rescue ships and helicopters, giving priority to incidents in high-risk areas. Updated risk assessment reports will be used to guide the use of rescue equipment and the dispatch of personnel. This highly dynamic and responsive resource adjustment can greatly improve the timeliness and effectiveness of rescue operations, record the decision and implementation details of each resource adjustment in detail, provide data support and decision-making basis for subsequent estimated adjustments, and obtain real-time resource adjustment records.

[0133] S503: Through real-time resource adjustment records, when facing sudden marine incidents, key rescue operations and resource dispatch are carried out to respond to and avoid losses and risks, and the execution process of obtaining marine emergency command and dispatch instructions is as follows;

[0134] When faced with sudden marine incidents, key rescue operations and resource dispatch are carried out according to the formula:

[0135]

[0136] In the formula, GR represents resource scheduling efficiency, P o Represents the priority coefficient of each resource, A o represents the availability of resources, Q represents the total response time, and n is the number of resources o;

[0137] Obtain the priority coefficient and availability of each resource from the real-time resource adjustment record. For example, the priority coefficient of the rescue vessel is 0.8 and the availability is 1 (fully available);

[0138] The helicopter has a priority factor of 0.9, an availability of 0.9 (partially available), and a total response time of 1 hour;

[0139] Substituting the values ​​into the formula:

[0140]

[0141] This calculation method provides a quantitative way to evaluate the overall efficiency of rescue operations, ensuring that key resources are optimally used when they are most needed. The resulting marine emergency command and dispatch instructions can accurately guide field operations and ensure the success of rescue operations.
