Satellite data receiving task scheduling system based on OSGI (Open Service Gateway Initiative) and workflow and satellite data receiving task scheduling method based on OSGI and workflow

Abstract

The invention discloses a satellite data receiving task scheduling system and a satellite data receiving task scheduling method. The system comprises a data receiving and recording task processing device, a data transmission task processing device, a quick-look task processing device, a filing task processing device, a quality monitoring task processing device, a record transmission task processing device, a transmission and retransmission task processing device, an operation flow monitoring device, a satellite receiving project management device, a satellite receiving project resolving processing device, a satellite receiving project monitoring device, a satellite receiving report processing device, a task completion checking device, a task planning device, a task checking device and a manual closed loop processing device. The system can be used for overcoming the defects of low development efficiency, poor system maintenance performance, poor expandability and the like of an original system, realizing system capitalization and enhancing the system expandability and the maintainability.

Description

technical field [0001] The present invention relates to the field of satellite data receiving and dispatching, in particular to a Java-oriented dynamic model system (Open Service Gateway Initiative, OSGI) and workflow for changing business content, business rules, and business processes in the field of satellite data receiving and operating scheduling. Satellite data receiving task scheduling system and method. Background technique [0002] Satellite data has played an increasingly important role in weather forecasting, geographic surveying and mapping, emergency disaster reduction, and scientific exploration. The satellite data receiving task scheduling system is the core of the management and scheduling of the satellite ground data receiving system. At present, the satellite ground data receiving system is responsible for domestic environmental disaster reduction satellites, China-Pakistan resource satellites, surveying and mapping resource satellites, practice series sate...

AI Technical Summary

Problems solved by technology

This method has a big disadvantage, that is, once the customer's business logic changes, for example, a new satellite launch requires satellite data reception service guarantee, all program modules need to be re-modified, compiled, and linked, which is a considerable workload

This design not only cannot meet the system requirements of the satellite data receiving task scheduling system with continuous increase of satellites and changing business, but also has low development efficiency and poor system maintainability, and seriously restricts the reliability, stability and reliability of the satellite ground data receiving task scheduling system. scalability
