Wireless communication node system for monitoring vibration of solar array of satellite

Abstract

The invention discloses a wireless communication node system for monitoring the vibration of a solar array of a satellite. The system comprises an array acquisition node acquisition module for acquiring data from acceleration sensors, an array acquisition node processor module for data framing, working state control and energy management, an array acquisition node wireless communication module for the wireless transmission and reception of the data, an array acquisition node energy management module for receiving control signals from the processor module and controlling the power supply of the acceleration sensors, the charging switching of storage batteries and the voltage and current monitoring of the storage batteries, and a control transmission node data transmission module for receiving remote control instructions transmitted from a vibration monitoring system, controlling the working modes of array acquisition nodes and transmitting the data of the acquisition nodes to the vibration monitoring system. According to the system, wireless communication nodes can be used for locally acquiring vibration sensor data on the solar array, and transmitting the acquired vibration sensor data to the interior of the satellite in a wireless way to acquire the vibration response data of the solar array when the solar array is unfolded in an injection section of the satellite and rotates in an in-orbit section of the satellite.

Description

technical field [0001] The invention relates to a wireless communication node system, in particular to a satellite solar panel vibration monitoring wireless communication node system. Background technique [0002] Some satellites have many payloads and are arranged facing the ground, and the installation distance of the payloads is short, so there is a high possibility of serious mutual interference during operation. Due to the large number of moving parts on the satellite, it is easy to generate vibration coupling with the solar panel, which will cause the oscillation of the satellite structure platform, which will inevitably reduce the detection accuracy of the satellite-borne remote sensing equipment and may even lead to the failure of its mission. In the ground test environment, the vibration response data of the solar panel can be transmitted by wire; in the space environment of the satellite in orbit, because the vibration monitoring acquisition node on the solar panel...

Problems solved by technology

Due to the large number of moving parts on the star, it is easy to generate vibration coupling with the solar panel, which will cause the oscillation of the satellite structure platform, which will inevitably reduce the detection accuracy of the spaceborne remote sensing equipment and may even lead to the failure of its mission.

In the ground test environment, the vibration response data of the solar panel can be transmitted by wire; in the space environment of the satellite in orbit, because the vibration monitoring acquisition node on the solar panel and the electronic equipment in the satellite cannot use the wired communication method, the solar panel is deployed. The vibration response data cannot be obtained when rotating
