Problems solved by technology
[0003] However, the existing control circuit only uses a control switch to control the storage battery to energize the deployment mechanism, so there is the following risk: before the launch of the satellite, during the ground test, if the control switch is closed due to an incorrect instruction, the sailboard will be deployed. The mechanism is energized for a long time, on the one hand, the sailboard is deployed by mistake, causing damage; on the other hand, the deployment mechanism is energized for a long time, resulting in failure

The invention provides a test method for preventing a satellite sailboard from being unfolded by mistake and a power supply circuit, and relates to the technical field of aerospace satellites. A breakpoint circuit is added in a power supply circuit, for supplying power to the satellite sailboard, of a satellite, and when the breakpoint circuit is disconnected, a first ground test in a folded state is performed on the satellite sailboard after the satellite assembly is completed; and after the satellite completes the first ground test and passes the first ground test, the breakpoint circuit is switched on through the first control instruction, so that the power supply circuit is switched on according to a second control instruction in an established flight program of the satellite. When the breakpoint circuit is switched off, the power supply circuit is not switched on, so that the situation that the power supply circuit is kept in an open circuit state and a satellite sailboard is unfolded mistakenly when the satellite is subjected to a first ground test can be effectively avoided, and the breakpoint circuit is switched on after the satellite passes the test, so that the satellite can be ensured to switch on the power supply circuit and unfold the satellite sailboard according to a set flight program.
Description
technical field [0001] The present application relates to the technical field of aerospace satellites, in particular, to a test method and power supply circuit for preventing false deployment of satellite sails. Background technique [0002] Before the launch of the satellite, the solar panels are in the folded state, and after the satellite is sent into the set orbit, it will be powered by the satellite program. Specifically, the working mechanism of the solar panel deployment control circuit is as follows: during the time period when the satellite sail is not deployed, the battery is used as an energy source to supply power to the deployment mechanism, and the satellite's star computer sends an instruction, and the control switch receives the "connection instruction" Afterwards, the switch is closed, and the unfolding mechanism acts to unfold the solar panel. [0003] However, the existing control circuit only uses a control switch to control the storage battery to energi...
