A highly reliable data publishing and storage method

Abstract

The invention belongs to the field of aerospace and aerospace, and specifically discloses a highly reliable data release storage system and method. The system is composed of data server groups A and B. Each server group includes a real-time data release server and a historical storage service. Each release server Both include an information collection module and a real-time data release module; each storage server includes a historical storage module, a historical data release module, and a data synchronization module; the method includes: browsing terminal data and establishing a heartbeat connection with the server group; Heartbeat information; the terminal judges whether to receive the information: if it has received it, the server group is normal, if it has not received it but received it within three cycles, it is normal, if it has not received it and it has not received it within three cycles, the server group is invalid ; If the data server group A and group B both fail, the system will fail and release will be suspended; the data synchronization module will perform data synchronization. The invention can realize the redundant backup of the entire system of the spacecraft data distribution and storage system.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a highly reliable data release storage system and method. Background technique [0002] With the development of space science and technology, the functions and structures of spacecraft are becoming more and more complex, and it is becoming more and more difficult for such a large and complex system to operate in the way the designer expected. In the process of spacecraft testing, the data transmission system used has higher requirements than traditional transmission methods, and a reliable data transmission system is the basis for the normal operation of spacecraft testing. Due to the requirements of test automation at this stage, the test process is executed independently by the equipment after issuing instructions. After being collected by the computer, the data is sent back and released to the browsing terminal for testers to browse and analyze in real time. If...

Problems solved by technology

If the communication link and storage link fail to cause data loss, the data publishing terminal is disconnected, and the test needs to be repeated, which will consume a lot of manpower, material resources, and financial resources; and the key data is not stored, resulting in data loss or incompleteness, which will also seriously affect subsequent data. analyze
