Embodiment Construction

[0042] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0043] see figure 1 , figure 2 , image 3 , Figure 4 , the autonomous control method of the spaceborne equipment on the micro-satellite of the present invention, at first, as figure 1 As shown, the power of the on-board equipment is controlled by the on-board computer, and the power switches of the on-board equipment are connected to the on-board computer (OBC) through a switch chip set or a relay set. Such as figure 2 As shown, the state of the onboard equipment is monitored through the onboard computer, that is, the signals between the onboard equipment are forwarded or processed through the onboard computer, and all telemetry data and equipment data are transmitted to the OBC for use by the OBC for judgment. According to the status of the...

Abstract

The invention discloses an independent control method and an independent control device of satellite-borne equipment on a microsatellite. A satellite-borne computer is used for controlling a power supply of the satellite-borne equipment, monitoring the state of the satellite-borne equipment and controlling the satellite-borne equipment to switch among a turnoff state, an operating state, an abnormal state and a failure state in accordance with the state of the satellite-borne equipment, so that the satellite can independently monitor and manage the satellite-borne equipment, the abnormity processing time can be greatly shortened, the safety of the satellite-borne equipment is improved, normal implementation of satellite missions is guaranteed, and additionally, the workload of ground measuring and control can be reduced.

Description

technical field [0001] The invention relates to the field of satellite on-board equipment, in particular to an autonomous control method for on-board equipment on a tiny satellite. Background technique [0002] On-board equipment refers to on-board equipment other than the on-board computer (OBC). For example, the on-board equipment of a microsatellite includes GPS, sun sensor, star sensor, momentum wheel, miniature inertial unit (MIMU), camera, atomic oxygen measuring instrument and AIS receiver, etc. [0003] Most of the time when the satellite is in orbit, it is outside the measurement and control range of the ground station, and managers cannot obtain the status of the satellite and implement control. At present, my country's satellites, especially the remote control of large satellites, can only be carried out when they are over the top. It takes time to receive, interpret, and send remote control commands. The real-time performance of equipment management is poor, and...
