Problems solved by technology

[0003] In related technologies, the data collection terminal in the SC-DCS system is usually only used to forward the collected data, but does not have the function of data storage. On the one hand, due to the functional limitations of the data collection terminal, the data collection terminal can only The data transmission is carried out when the satellite enters the communication range, that is, the data sampling period is consistent with the satellite operation period, and the time for the satellite to pass through the communication range is usually several hours or even dozens of hours, resulting in a relatively long sampling period in the SC-DCS system. Long, unable to perform higher frequency data sampling
[0004] On the other hand, since the data collection terminal does not have the function of data storage, when the communication status between the data collection terminal and the satellite is not good, even if the SC-DCS system finds that the data collected at the current time is lost, the current time cannot be retrieved. The collected data leads to a decrease in the reliability of the data collection function of the SC-DCS system

Abstract

The invention provides a data acquisition terminal and method based on a space-based data integrated acquisition system. The data acquisition terminal based on the space-based data integrated acquisition system comprises a signal receiving module used for receiving a first satellite signal sent by a first satellite, and recording the first satellite signal as to-be-sent data; a control module, which is electrically connected to the signal receiving module, a signal sending module and a solid state storage module, and used for sending the to-be-sent data to the solid state storage module when determining that a distance between a second satellite and an Internet of Things data transmission terminal is greater than or equal to a preset distance; and the solid state storage module, which is electrically connected to the control module and used for storing the to-be-sent data sent by the control module. The technical scheme of the invention is beneficial to improving the integrity of dataacquired in multiple continuous sampling periods, reducing the possibility of acquired data loss, and improving the response rate of processing the to-be-sent data.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a data collection terminal based on a space-based data comprehensive collection system and a data collection method based on a space-based data comprehensive collection system. Background technique [0002] Space-born Comprehensive Data Collection System (SC-DCS) adopts the technologies of telemetry, remote control and remote monitoring in aerospace, and transmits the collected data from the remote data collection platform to the data processing center through satellites. The data is processed by the data processing center and delivered to users. [0003] In related technologies, the data collection terminal in the SC-DCS system is usually only used to forward the collected data, but does not have the function of data storage. On the one hand, due to the functional limitations of the data collection terminal, the data collection terminal can only The data transmi...
