Description

Technical Field

[0001] The present invention relates to the field of satellite applications, and in particular to a system and method for quickly reporting and feeding back satellite remote sensing observation requirements in a cross-network direct connection manner. Background Art

[0002] At present, with the increasing demand of ground users for remote sensing information, the existing conventional observation methods can no longer meet the application needs. The traditional human observation method requires observers to cross mountains and reach the site for observation. Although this method has high observation accuracy, it is difficult, time-consuming and risky for observers to get close to the observation location. At present, with the continuous development of drone technology, aerial observation based on drones has become an important development direction in the observation field in recent years. However, on the one hand, the observation capability of hundreds of kilometers requires high performance of the drone itself, and long-flight drones are still a research difficulty in the field of civil drone development; on the other hand, although drones have a long flight distance, the observation distance is short, and observation still needs to fly to the target. Observation in unfamiliar areas without meteorological data is more challenging to drone flight safety.

[0003] Satellite remote sensing observation is a means of implementing earth observation based on remote sensing satellites. Although its observation capability is relatively dependent on satellite performance, the current remote sensing satellite imaging technology has made great progress. The mainstream remote sensing satellite imaging mechanism has covered multiple forms such as visible light imaging, infrared imaging, and synthetic aperture radar imaging. The resolution has reached the sub-meter level, which is fully capable of meeting the needs of accurate ground observation. It can be seen that applying satellite remote sensing observation to ground application networks can meet the global observation needs of ground application network users and has broad application prospects.

[0004] However, the current remote sensing satellite network and ground application network belong to networks of different natures. Relevant security protection regulations require the establishment of a reliable security barrier between the two networks, which leads to the lack of fast and efficient communication channels and means between the two networks. Usually, data communication can only be completed by relying on the inefficient method of CD ferrying. For example, the existing invention patent application document "System, method, device and medium for secure interaction of large-capacity files between physically isolated networks" with publication number CN116346910A sets an Internet data ferrying task scheduling server on the Internet side, and sets an intranet data ferrying task scheduling server on the intranet side. CD ferry machines 1 and CD ferry machines 2 are set between the two task scheduling servers. The ferrying task is initiated by triggering business system data and ferrying results. The Internet data ferrying task scheduling server and the intranet data ferrying task scheduling server create data transmission tasks, control data subpackaging, build a data transmission fault-tolerant mechanism, and perform security verification. Data is written through CD ferry machines 1 and CD ferry machines 2 to control data interaction scheduling between the internal and external networks. And the existing invention patent application document "A Satellite Image Data Intelligent Publishing System" with publication number CN115358729A includes: a publishing data management module selects publishing data according to publishing rules, and a cross-network data automatic interaction module securely migrates the received publishing data from the intranet to the external network and stores it in the database; a data publishing intelligent service module accesses the database according to user portraits and provides data publishing intelligent services; a data publishing operation and maintenance management module monitors the operating status of the system and provides a visual monitoring and management interface; a data publishing application terminal module allows users to register, log in and access the data publishing intelligent service module. Among them, the cross-network data automatic interaction module includes a data import processing unit, an optical disk ferry device unit, a data export processing unit and a data backup unit, wherein: the data import processing unit is used to perform data source verification, data extraction, data cleaning, format conversion, data loading and data desensitization on the metadata, original data provided by the intranet and the business data information, historical data and data statistical information produced by the system, to form an intermediate library to prepare data for optical disk ferrying; the optical disk ferry device unit is used to control the automated optical disk ferry machine to simulate manual operation of the optical disk by humans, to move the burned optical disk in the burning optical disk drive to the read-only optical disk drive through a robot for reading, and to realize automatic data migration between physically isolated networks; the data export processing unit is used to receive the ferry data exported by the optical disk ferry device unit, store it into the library to form an export intermediate library, and to provide safe and controllable business data support for the system; the data backup unit is used to manually back up various types of business data of the system and automatically back up according to the strategy, and to configure and manage various parameters of the backup strategy, and to restore the system data according to the backup data during the system maintenance period.In the above existing solutions, it is difficult for users of the ground application network to quickly and efficiently submit their satellite remote sensing observation task request information to the remote sensing satellite network operation and maintenance management department, and it is also difficult for the remote sensing satellite network operation and maintenance management department to promptly process the satellite remote sensing observation task requests of the demanders and efficiently push remote sensing observation images. In order to effectively improve the remote sensing satellite network's satellite remote sensing observation information guarantee capabilities for the ground application network, the above problems need to be solved urgently.
