Description

A method and system for enabling satellite-based pre-scheduling and mobile typhoon observation. Technical Field

[0001] This invention belongs to the field of meteorological monitoring technology, specifically a method and system for realizing satellite-based pre-scheduled mobile observation of typhoons. Background Technology

[0002] Tropical cyclones are rapidly rotating atmospheric vortex systems that originate over tropical or subtropical oceans and may move towards land. Once a typhoon makes landfall, it typically triggers direct disasters such as strong winds, torrential rains, and storm surges, making it one of the major hazardous weather systems. Typhoon forecasting is one of the most important technical methods for typhoon disaster prevention and mitigation, and typhoon forecasting services should be based on strengthened tracking and monitoring. For typhoons entering my country's maritime monitoring and early warning areas, their movements should be closely monitored and analyzed, and intensive observations should be conducted as needed to provide the latest real-time information for typhoon location and path forecasting, and to accumulate necessary data and information for related research.

[0003] Typhoons have a life cycle. During their formation phase, the initial stage of a typhoon is a tropical depression. From the initial low-pressure circulation to the maximum average wind speed near the center reaching level 8, it generally takes about 2 days, sometimes three or four days, and sometimes only a few hours. During the development phase, the typhoon continuously absorbs energy until the central pressure reaches its lowest value and the wind speed reaches its maximum value.

[0004] Current technology only addresses typhoon forecasting; it lacks effective solutions to the problems of insufficient intelligence and poor mobility in typhoon observation systems. Summary of the Invention

It performs continuous, rapid, multi-channel imaging observations of a region in geostationary orbit, directly serving weather analysis and forecasting, climate prediction, and environmental and disaster monitoring. The observation bands cover visible panchromatic, true color, shortwave infrared, and longwave infrared bands. It employs a scanning imaging method with one fixed-area scan (56s) and one cold-air observation (4s) every 1 minute, covering an observation range of 2000km × 1800km (north-south × east-west, 1000 pixels × 900 pixels).

[0048] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] This application provides a method and system for satellite-based pre-scheduled mobile observation of typhoons, addressing the issues of insufficient intelligence and poor mobility in typhoon observation systems, thereby enabling real-time monitoring of typhoons.

[0050] Figure 1 shows a method for implementing satellite-based pre-scheduling and mobile typhoon observation according to an embodiment of the present invention, comprising:

[0051] Step 101: Obtain the forecast for the target typhoon and get the forecast information;

[0052] Intelligent analysis is performed on typhoon initiation reports, typhoon cessation reports, typhoon reports, and typhoon satellite guidance reports issued by meteorological observatories. Furthermore, it intelligently analyzes all typhoon initiation reports, typhoon cessation reports, typhoon location and intensity reports, typhoon reports, and typhoon satellite guidance reports issued by the National Meteorological Center's Taiwan Strait Center hourly. This analysis yields a summary of mobile typhoon observation mission requirements for the rapid imager. This summary includes at least one of the following: forecast information, user typhoon observation requirements, typhoon tracking observation requirements, and typhoon location and intensity observation mission requirements.

[0053] The forecast information includes: typhoon location, time, intensity, direction of movement, speed, and numbering boundaries.

[0054] Step 102: Based on the forecast information, establish a first observation task and set a first observation range;

[0055] Based on the monitoring information of the target typhoon's location and intensity in the summarized information of the mobile observation mission requirements, as well as the forecast information of the target typhoon's movement speed, direction of movement, and intensity, intelligent planning is used to obtain the first observation range, typhoon mobile observation time, typhoon mobile observation frequency, and typhoon mobile observation trajectory observation mission information for the scanner-based intelligent typhoon. The first observation range is the same as the range of the numbered boundary.

[0056] Step 103: Obtain real-time information on the target typhoon, and obtain the second observation range based on the real-time information;

[0057] Step 104: Determine the location of the instantaneous center point based on the instantaneous information and the second observation range;

[0058] Step 105: Establish a second observation task based on the real-time information, and iterate the observation task in real time.

[0059] Based on the satellite observation target typhoon information obtained at time T in step 102, i.e. real-time information, the second observation range of the scanner intelligent typhoon is obtained through intelligent planning, and the real-time center point of the typhoon is confirmed. A second observation task is established with the observation task information of typhoon maneuvering observation time, typhoon maneuvering observation frequency, and typhoon maneuvering observation trajectory, and the first observation task is iterated upon.

[0060] As shown in Figure 2, the forecast information described in this embodiment of the invention includes establishing a first observation task and setting a first observation range. The specific steps include:

[0061] Step 201: Based on the forecast information, predict the time T when the target typhoon reaches the monitoring warning line and the location of the target typhoon at time T;

[0062] Step 202: Based on the pre-judged target typhoon position at time T, obtain the center point position of the target typhoon at time T.

[0063] Step 203: Based on the center point location of the target typhoon, establish an observation task at time T and set a first observation range that is the same as the range of the number boundary.

[0064] As shown in Figure 3, this embodiment of the invention obtains real-time information at time T from satellite observation of the target typhoon: the real-time radius, real-time position, and real-time moving speed of the typhoon, and obtains the second observation range. The specific steps are as follows:

[0065] Step 301: Adjust the first observation range according to the radius of the instantaneous typhoon to obtain the second observation range.

[0066] Step 302: Determine the location of the instantaneous center point based on the instantaneous information and the second observation range.

[0067] Step 303: Determine the instantaneous center point position based on the instantaneous position and the second observation range, and at the same time determine whether there is a deviation between the center point position of the target typhoon at time T and the predicted center point position.

[0068] Step 304: Establish a second observation task based on the real-time information, and iterate the observation task in real time.

[0069] Based on the instantaneous movement speed, the displacement trajectory is calculated piecewise using the linear interpolation method, starting from time T and adding up stepwise at time intervals until the center point at time T+48h.

[0070] Based on the latitude data of the target typhoon at time T and the latitude data of the forecast target typhoon, the latitude of the target typhoon center in the next 48 hours is calculated by using a linear arithmetic sequence to calculate the hourly difference. To reduce errors, the calculation is performed in segments according to the time interval of the typhoon forecast results.

[0071] When a typhoon is located between the initial numbering boundary and the 48-hour warning line, based on the real-time latitude data of the typhoon at time T from multiple satellites, and the typhoon latitude data of the typhoon forecast results at T+12h, T+24h, T+36h, and T+48h, the hourly typhoon latitude data from T+1h to T+11h, T+13h to T+23h, and T+37h to T+47h are calculated using the linear interpolation method.

[0072] The typhoon is located between the 48-hour and 24-hour warning lines. Based on the real-time latitude data of the typhoon at time T from multiple satellites, and the typhoon forecast latitude data at T+12h, T+24h, T+36h, and T+48h, the hourly typhoon latitude data from T+1h to T+11h, T+13h to T+23h, and T+37h to T+47h are calculated using linear interpolation.

[0073] The typhoon is within the 24-hour warning line. Based on the typhoon forecast results and multi-satellite real-time typhoon latitude data at time T, as well as the typhoon latitude data at T+6h, T+12h, T+18h, T+24h, T+36h, and T+48h, hourly typhoon latitude data from T+1h to T+5h, T+7h to T+11h, T+13h to T+17h, T+19h to T+23h, T+25h to T+35h, and T+37h to T+47h were calculated using linear interpolation.

[0074] Based on the latitude and longitude data of the actual target typhoon center location at time T and the latitude and longitude data of the predicted center location of the planned observation area at time T, the position error (QUOTE) is calculated. ), shift error (QUOTE) ) and speed error (QUOTE) The error calculation results are sent to the intelligent scheduling subsystem for typhoon mobile observation tasks. The path error is the distance between the predicted and actual positions of the typhoon center. The path error can be decomposed into two error components: the error component along the observed typhoon's path (Along-track) and the error component perpendicular to the observed typhoon's path (Cross-track).

[0075] Establish several second observation tasks from time T to time T+48h, and iterate the second observation tasks in real time based on the real-time information of the target typhoon obtained at each time.

[0076] Figure 4 shows a system for intelligent maneuvering observation of typhoons via satellite pre-planning according to an embodiment of the present invention, comprising:

[0077] The acquisition module 401 is used to acquire information about the target typhoon. Specifically, it is used to intelligently sense and automatically parse the summary information of the mobile observation task requirements of the rapid imager typhoon based on the user's observation needs and the typhoon forecast of the National Meteorological Center. The summary information of the mobile observation task requirements includes at least one of the following: typhoon forecast information, user typhoon observation requirement information, typhoon tracking observation requirement information, and typhoon positioning and intensity determination observation task requirement information.

[0078] The system automatically receives typhoon forecast messages issued by the meteorological center at time T+1h and intelligently analyzes the typhoon's movement direction, speed, and intensity information provided in the messages for T+6h, T+12h, T+18h, T+24h, T+36h, T+48h, T+60h, T+72h, T+96h, and T+120h. Specifically, when a typhoon is located between the starting number boundary and the 48h warning line, only the typhoon's movement direction, speed, and intensity information for T+12h, T+24h, T+36h, T+48h, T+60h, T+72h, T+96h, and T+120h is analyzed; when a typhoon is located between the 48h warning line and the 24h warning line, only the typhoon's movement direction, speed, and intensity information for T+12h, T+24h, T+36h, and T+120h is analyzed. Typhoon movement direction, speed, and intensity information for +48h, T+60h, T+72h, T+96h, and T+120h; Typhoon is within the 24h warning line, with analysis and forecast of typhoon movement direction, speed, and intensity information for T+6h, T+12h, T+18h, T+24h, T+36h, T+48h, T+60h, T+72h, T+96h, and T+120h.

[0079] The system automatically receives typhoon satellite guidance reports issued by the meteorological center at time T+15min, and intelligently analyzes all typhoon real-time location latitude and longitude information and all typhoon intensity monitoring information provided in the typhoon satellite guidance reports at time T (intensity information is no longer included during landfall).

[0080] It receives typhoon termination reports in real time and intelligently analyzes the latitude and longitude information of all typhoon termination locations provided in the reports.

[0081] The first task module 402 is used to establish a first observation task and set a first observation range based on the forecast information.

[0082] The second task module 403 is used to obtain real-time information about the target typhoon and a second observation range; and to determine the real-time center point location based on the real-time information and the second observation range, and to establish a second observation task.

[0083] Execution module 404 is used to execute the first task module and the second task module;

[0084] Update module 405 for real-time iterative observation tasks.

[0085] In practical implementation, based on user observation needs and using typhoon forecasts from the National Meteorological Center as the basis, the system intelligently senses and automatically analyzes the information gathered from the rapid imager's typhoon mobile observation mission requirements. This information includes typhoon forecasts, user typhoon observation needs, typhoon tracking and observation needs, and typhoon location and intensity assessment. Based on the target typhoon's reported location, intensity, and forecast information such as its speed, direction, and intensity, the system intelligently plans the rapid scanner's intelligent typhoon mobile observation range, observation time, frequency, and trajectory. This information is combined with satellite platform management tasks and ground application system operational arrangements to make comprehensive intelligent decisions, enabling intelligent satellite-ground scheduling of typhoon mobile observation missions. The system automatically generates a rapid imager typhoon mobile observation mission schedule and performs intelligent and rapid deployment. During typhoon mobile observation, the intelligent analysis of typhoon observation results is updated every 1 hour. The rapid imager typhoon mobile observation system has intelligent automated maintenance capabilities, enabling one-click start and stop of the system; and can be intelligently configured according to the typhoon observation needs of the payload and the adaptability between ground application systems to achieve intelligent operation and maintenance between space and ground.

[0086] As can be seen from the above description, this application achieves the following technical effects:

[0087] Based on observation requirements and typhoon forecasts from the meteorological center, the system intelligently senses and automatically analyzes the summary information of the rapid imager's typhoon mobile observation mission requirements. This summary information includes the target typhoon's reported location and intensity, as well as forecasts of its speed, direction, and intensity. The system then intelligently plans the scanner's mobile typhoon observation range, observation time, frequency, and trajectory. This achieves intelligent decision-making by combining satellite platform management and ground application system operational arrangements, enabling intelligent scheduling of typhoon mobile observation missions between the satellite and ground systems. Simultaneously, it automatically generates a rapid imager typhoon mobile observation mission schedule and enables intelligent and rapid deployment, thus solving the technical problems of insufficient intelligence and poor mobility in typhoon observation systems.

[0088] As shown in Figure 5, the acquisition module 401 of this embodiment of the invention includes:

[0089] The first acquisition unit 411 is used to acquire the target typhoon forecast and obtain the forecast information;

[0090] The second acquisition unit 412 is used to acquire real-time information about the target typhoon at time T.

[0091] As shown in Figure 5, the execution module 404 of this embodiment of the invention further includes:

[0092] Adjustment unit 414 is used to adjust the observation range, specifically adjusting the first observation range to the second observation range.

[0093] The adjustment unit updates the center position planning parameters of the observation area on the typhoon maneuvering mission schedule based on the real-time typhoon maneuvering observation image center point path planning data. It also updates the system in real-time based on the error calculation results between the center position of the observation area and the typhoon center position from the intelligent typhoon maneuvering observation path planning subsystem, intelligently determining whether the error exceeds the limit. If the error exceeds the limit, it has the capability to real-time dispatch the intelligent path planning subsystem to update the observation path planning and the intelligent decision-making subsystem for observation missions to update the mission schedule based on the new path planning. This avoids excessive updates to the mission schedule and frequent commands from the ground application system, which can cause system pressure and risks.
