Description

Technical Field

[0001] This application relates to the field of satellite communication technology, and in particular to a method, apparatus, and electronic equipment for collaborative monitoring using high and low orbit satellites. Background Technology

[0002] With the continuous development of satellite monitoring technology, collaborative monitoring by high-Earth orbit and low-Earth orbit satellites has become a key approach to improve the timeliness and accuracy of disaster response. High-Earth orbit satellites have the advantage of wide-area coverage and can quickly locate abnormal areas; low-Earth orbit satellites, with their high resolution and short revisit cycles, can achieve refined dynamic tracking. Through intelligent task scheduling and data fusion mechanisms, the two significantly shorten the closed-loop time of "sensing-analysis-early warning".

[0003] However, in existing high- and low-orbit satellite collaborative monitoring methods, the monitoring tasks undertaken by high-orbit and low-orbit satellites for ground disaster monitoring overlap. For example, high-orbit satellites are overly involved in monitoring local details, while low-orbit satellites are often assigned wide-area scanning tasks. This leads to unreasonable use of computing power by low-orbit and high-orbit satellites for disaster monitoring during the monitoring process, resulting in a decrease in the accuracy and real-time performance of disaster monitoring and handling.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This application provides a method for collaborative monitoring using high and low orbit satellites, which can be executed by an electronic device. The electronic device can be a server, which can be an independent physical server, a server cluster composed of multiple physical servers, a distributed device, or a cloud server that provides cloud computing services. The server is installed on a high orbit satellite.

[0027] Reference Figure 1A method for collaborative monitoring using high and low orbit satellites includes steps S101, S102, S103 and S104, wherein, in step S101, initial monitoring information corresponding to the target monitoring area is obtained.

[0028] In some embodiments, the target monitoring area is an area with ground disasters. The area with ground disasters can be the entire area of ​​the target monitoring area or a part of the target monitoring area. The initial monitoring information is the monitoring information collected by high-orbit satellites that are capable of monitoring the target monitoring area.

[0029] When a high-orbit satellite receives a monitoring task from a ground terminal, it monitors the disaster situation within the target monitoring area and collects initial monitoring information related to the disaster. The initial monitoring information is then sent to electronic devices. This initial monitoring information includes terrain information, information representing the living conditions of people, and information on the distribution of people in clusters.

[0030] S102, based on the initial monitoring information, the target monitoring area is divided to obtain multiple sub-target monitoring areas and monitoring instructions corresponding to each sub-target monitoring area.

[0031] In some embodiments, the sub-target monitoring area is a portion of the target monitoring area, and each sub-target monitoring area has one and only one terrain type; the monitoring instruction is an instruction to control the low-orbit satellite to monitor its corresponding sub-target monitoring area, and the monitoring instruction includes computing power allocation instructions and monitoring frequency instructions, as well as computing power allocation information.

[0032] The electronic equipment analyzes the initial monitoring information to determine the terrain distribution and population distribution of the target monitoring area. Based on the terrain distribution, it obtains terrain edge monitoring information within the target monitoring area, and based on the population distribution, it obtains clustered residential monitoring information within the target monitoring area. Based on the terrain edge monitoring information, the electronic equipment determines the boundary lines between different terrains within the target monitoring area, and divides the target monitoring area based on the boundary lines to obtain multiple sub-target monitoring areas corresponding to the target monitoring area. At the same time, based on the terrain edge monitoring information and clustered residential monitoring information, the electronic equipment determines the geo-residential association strength information corresponding to different terrains. The geo-residential association strength information can be low, medium, or high.

[0033] Subsequently, the electronic equipment generates monitoring instructions corresponding to each sub-target monitoring area based on the clustered residential monitoring information and the geo-residential association strength information. The monitoring instructions are the instructions that enable the low-orbit satellite to specify the intensity and frequency of monitoring of the sub-target monitoring area it is responsible for.

[0034] S103, based on multiple monitoring commands, determines the target low-orbit satellites corresponding to the monitoring areas of multiple sub-targets, and sends the monitoring commands to the corresponding target low-orbit satellites.

[0035] In some embodiments, after determining multiple monitoring instructions, the electronic device analyzes each monitoring instruction to determine the monitoring requirements for the corresponding sub-target monitoring area, namely the requirements for computing power allocation and monitoring frequency. After analyzing the monitoring instructions, the electronic device obtains computing power allocation instructions and monitoring frequency instructions.

[0036] Subsequently, the electronic equipment acquires the remaining computing power information and monitorable area information corresponding to multiple preliminary low-Earth orbit satellites, and uses the remaining computing power information and monitorable area information as the basis for screening multiple preliminary low-Earth orbit satellites. Specifically, the electronic equipment matches the sub-target monitoring area with multiple monitorable area information, and matches the computing power allocation information contained in the computing power allocation command with multiple remaining computing power information, thereby screening out the target low-Earth orbit satellite corresponding to each sub-target monitoring area from multiple preliminary low-Earth orbit satellites. The monitoring command also includes a monitoring frequency command. After determining the target low-Earth orbit satellite corresponding to each sub-target monitoring area, based on the monitoring frequency command, the target low-Earth orbit satellite is controlled to periodically monitor and collect information on its corresponding sub-target monitoring area.

[0037] S104: After obtaining the final monitoring information corresponding to the target low-orbit satellite, determine the disaster early warning information based on the final monitoring information and send the disaster early warning information to the target terminal.

[0038] In some embodiments, during the process of an electronic device sending multiple monitoring commands to their respective target low-Earth orbit satellites so that the target low-Earth orbit satellites can monitor their corresponding sub-target monitoring areas, the target low-Earth orbit satellites send the collected final monitoring information to the electronic device. The electronic device analyzes and processes the final monitoring information to determine the processing and transmission rules for the final monitoring information, and processes the final monitoring information according to the processing and transmission rules to obtain disaster early warning information, and sends the disaster early warning information to its adapted target terminal.

[0039] By using initial monitoring information acquired from high-orbit satellites, the target monitoring area is divided, and low-orbit satellites are identified for each of the multiple sub-target monitoring areas. The low-orbit satellites then perform refined observations of their respective sub-areas using reasonable computing power, and the data is transmitted back to the high-orbit satellites for fusion analysis. Disaster early warning information is then adaptively sent out. In this way, by combining initial monitoring by high-orbit satellites with joint regional and reasonable computing power monitoring by multiple low-orbit satellites, the accuracy and timeliness of disaster monitoring within the target monitoring area are improved.

[0040] Step S102: Based on the initial monitoring information, the target monitoring area is divided to obtain multiple sub-target monitoring areas and monitoring instructions corresponding to each sub-target monitoring area. This includes: determining the terrain edge monitoring information and clustered residential monitoring information corresponding to the target monitoring area based on the initial monitoring information; dividing the target monitoring area based on the terrain edge monitoring information to obtain multiple sub-target monitoring areas; determining the geo-residential association strength information corresponding to the target monitoring area based on the terrain edge monitoring information and clustered residential monitoring information; and determining the monitoring instructions corresponding to each of the multiple sub-target monitoring areas based on the clustered residential monitoring information and geo-residential association strength information.

[0041] In some embodiments, terrain edge monitoring information reflects the edge distribution between different terrains within the target monitoring area; clustered residential monitoring information reflects the residential distribution and clustering of people within the target monitoring area; and geo-residential association strength information reflects the degree of residential dependence of people in different terrain areas.

[0042] The electronic equipment analyzes and processes the initial monitoring information to obtain the distribution of different terrain features within the target monitoring area, the boundary areas between different terrain features, and the distribution of human settlements. Subsequently, the electronic equipment uses the distribution of different terrain features and boundary areas as the basis for dividing the target monitoring area into multiple sub-target monitoring areas. Specifically, after dividing the target monitoring area into multiple sub-target monitoring areas based on terrain edge monitoring information, the electronic device determines the population density corresponding to each sub-target monitoring area. Subsequently, the electronic device associates the terrain and population density corresponding to each sub-target monitoring area, and determines the geo-residential correlation strength information corresponding to each sub-target monitoring area based on the population density. For example, if the population density is not greater than a first preset population density, the geo-residential correlation strength information corresponding to its sub-target monitoring area is determined to be low correlation strength; if the population density is not less than the first preset population density and not greater than the second preset population density, the geo-residential correlation strength information corresponding to its sub-target monitoring area is determined to be medium correlation strength; and if the population density is not less than the second preset population density, the geo-residential correlation strength information corresponding to its sub-target monitoring area is determined to be high correlation strength.

[0043] Subsequently, the electronic equipment uses information on clustered residential monitoring and the strength of geographical residential associations to determine the monitoring intensity, i.e., the amount of computing power allocated and the monitoring frequency, for the sub-target monitoring area.

[0044] In some embodiments, based on clustered residential monitoring information and geo-residential association strength information, monitoring instructions corresponding to multiple sub-target monitoring areas are determined, including: determining the population density corresponding to each of the multiple sub-target monitoring areas based on clustered residential monitoring information, and determining the basic computing power allocation information corresponding to each of the multiple sub-target monitoring areas based on the multiple population densities; determining the surrounding area association information corresponding to each of the multiple sub-target monitoring areas based on the geo-residential association strength information, and determining the monitoring frequency information corresponding to each of the multiple sub-target monitoring areas based on the surrounding area association information; and generating monitoring instructions corresponding to each of the multiple sub-target monitoring areas based on the basic computing power allocation information and the monitoring frequency information.

[0045] In some embodiments, the electronic device analyzes the residential locations of residents within the target monitoring area based on clustered residential monitoring information, and determines the resident density within each sub-target monitoring area based on the resident locations. Subsequently, it compares the resident density with a preset density-computing power mapping table to obtain the basic computing power allocation information corresponding to each sub-target monitoring area. Simultaneously, it combines the geo-residential association strength information, dynamically weights the population flow, traffic nodes, and historical event data of the surrounding area, determines the surrounding area association information corresponding to each sub-target monitoring area, and then derives the monitoring frequency adjustment coefficient, i.e., the monitoring frequency information. Subsequently, the electronic device integrates the basic computing power allocation information and the monitoring frequency information to generate a monitoring instruction that includes a computing power threshold, monitoring cycle, and triggering conditions.

[0046] In some embodiments, when the monitoring instructions include computing power allocation instructions, step S103, based on multiple monitoring instructions, determines the target low-Earth orbit satellites corresponding to multiple sub-target monitoring areas, including: acquiring the remaining computing power information and monitorable area information corresponding to multiple preliminary low-Earth orbit satellites; matching the multiple monitorable area information and multiple sub-target monitoring areas to determine the multiple preliminary low-Earth orbit satellites corresponding to the multiple sub-target monitoring areas; and matching the remaining computing power information corresponding to the multiple preliminary low-Earth orbit satellites with the computing power allocation instructions to determine the target low-Earth orbit satellites corresponding to the multiple sub-target monitoring areas.

[0047] In some embodiments, multiple initial low-orbit satellites can perform disaster monitoring for parts of the target monitoring area, but due to limitations in orbital position, energy status, and communication bandwidth, a single satellite cannot provide full coverage of the target monitoring area.

[0048] The electronic device generates an information acquisition command and sends it to multiple initial satellites. These initial satellites respond to the command by sending their remaining computing power and the monitorable area information they can monitor back to the electronic device. The electronic device compares the monitorable area information with the sub-target monitoring areas, selecting the initial low-Earth orbit (LEO) satellites with the highest matching degree to each sub-target monitoring area. Then, the electronic device compares the remaining computing power information of each initial LEO satellite with the computing power threshold included in the computing power allocation command corresponding to the sub-target monitoring area, selecting the initial LEO satellite with remaining computing power not lower than the corresponding threshold, and using this initial LEO satellite as the target LEO satellite for monitoring the sub-target monitoring area.

[0049] In some embodiments, the remaining computing power information corresponding to multiple preliminary low-Earth orbit satellites is matched with computing power allocation instructions to determine the target low-Earth orbit satellites corresponding to multiple sub-target monitoring areas. This includes: when the remaining computing power information corresponding to at least two of the multiple preliminary low-Earth orbit satellites is greater than the computing power allocation information contained in the computing power allocation instructions, determining the monitorable time period corresponding to at least two preliminary low-Earth orbit satellites and the temporary additional task information corresponding to the monitorable time period; obtaining the computing power increase corresponding to the temporary additional task information, and determining the target remaining computing power information corresponding to at least two preliminary low-Earth orbit satellites based on the computing power increase and the remaining computing power information; and selecting the target low-Earth orbit satellite from the at least two preliminary low-Earth orbit satellites based on the target remaining computing power information.

[0050] In some embodiments, if an electronic device determines that the remaining computing power information corresponding to at least two of the multiple preliminary low-orbit satellites is greater than the computing power allocation information contained in the computing power allocation instruction, it indicates that the at least two preliminary low-orbit satellites have excess computing power carrying capacity, that is, they have the potential to provide redundant computing power support for disaster monitoring in the sub-target monitoring area.

[0051] At this point, the electronic equipment can further screen at least two preliminary low-Earth orbit satellites to obtain more suitable target low-Earth orbit satellites. Specifically, the electronic equipment acquires the operational information corresponding to at least two preliminary low-Earth orbit satellites and determines the monitorable time period corresponding to each of the at least two preliminary low-Earth orbit satellites based on the operational information, as well as the information on any potential additional tasks that may be added within the monitorable time period. Subsequently, the electronic equipment accumulates the amount of computing power increase corresponding to the acquired additional task information with the remaining computing power information of the corresponding preliminary low-Earth orbit satellites to obtain the target remaining computing power information corresponding to each of the at least two preliminary low-Earth orbit satellites.

[0052] The electronic device calculates the difference between the remaining computing power information of the target and the computing power allocation information contained in the computing power allocation instruction, obtains at least two computing power differences, compares the at least two computing power differences, selects the largest computing power difference, and identifies the target low-orbit satellite corresponding to the largest computing power difference as the target low-orbit satellite, thereby maximizing the optimization of computing power redundancy of the target low-orbit satellite when performing sub-target monitoring tasks.

[0053] Step S104: After obtaining the final monitoring information corresponding to the target low-orbit satellite, based on the final monitoring information, determine disaster early warning information and send the disaster early warning information to the target terminal. This includes: based on the final monitoring information, determining the disaster information corresponding to multiple sub-target monitoring areas respectively; based on the disaster information, determining the disaster level corresponding to multiple sub-target monitoring areas respectively; if any disaster level among the multiple disaster levels is greater than a preset disaster level, generating a direct forwarding instruction and sending the direct forwarding instruction to the target low-orbit satellite corresponding to any disaster level, so that the target low-orbit satellite generates disaster early warning information based on the final monitoring information it has obtained, and sends the disaster early warning information to the target terminal within the sub-target monitoring area corresponding to the target low-orbit satellite.

[0054] In some embodiments, after acquiring the final monitoring information, the electronic device performs multi-dimensional feature extraction on the final monitoring information to obtain the disaster information corresponding to each sub-target monitoring area. Subsequently, the disaster information is input into a pre-trained disaster level determination model to output the disaster level corresponding to each sub-target monitoring area, or the built-in rule base is directly called to match the mapping relationship between disaster type and impact level to complete the level determination, thereby obtaining the disaster level.

[0055] The electronic device compares multiple disaster levels with preset disaster levels. If it determines that any disaster level is greater than the preset disaster level, it indicates that the disaster severity in the sub-target monitoring area corresponding to that disaster level is too high or poses a serious threat to the safety of people's lives and property. In this case, it can be considered to directly generate and broadcast disaster warning information by the determined target low-orbit satellite to improve the efficiency of the warning. That is, the electronic device generates a direct forwarding command and sends the direct forwarding command to the target low-orbit satellite corresponding to any disaster level, so that the target low-orbit satellite generates disaster warning information and sends the disaster warning information to the target terminal in its corresponding sub-target monitoring area. The target terminal can be an emergency command center, community broadcasting system or resident smartphone in the sub-target monitoring area.

[0056] In some embodiments, after determining the disaster levels corresponding to multiple sub-target monitoring areas based on disaster information, and obtaining the final monitoring information corresponding to the target low-orbit satellite, disaster early warning information is determined based on the final monitoring information, and the disaster early warning information is sent to the target terminal. The method further includes: if multiple disaster levels are not greater than a preset disaster level, obtaining resident density information corresponding to multiple sub-target monitoring areas, and generating disaster early warning information corresponding to multiple disaster levels; sorting the multiple disaster early warning information based on the multiple resident density information, and sequentially sending the sorted multiple disaster early warning information to the target terminals within their respective sub-target monitoring areas.

[0057] In some embodiments, when the electronic device determines that multiple disaster levels are not greater than a preset disaster level, it indicates that the degree of disaster is limited. In this case, in order to prevent the degree of disaster from expanding, it is necessary to continuously monitor it with low-orbit satellites. Therefore, early warnings can be sent through high-orbit satellites. Thus, the electronic device generates disaster early warning information corresponding to multiple disaster levels, and sorts the multiple disaster early warning information based on the population density information corresponding to each sub-target monitoring area. Based on the order of sorting, the multiple disaster early warning information is sent sequentially to the target terminal in its respective sub-target monitoring area. The target terminal can be the terminal equipment of the emergency command center in the sub-target monitoring area.
