Abstract

The invention relates to a programmable direct-current voltage stabilizing power supply for optical fiber gyroscope testing. The programmable direct-current voltage stabilizing power supply comprisesa shell and a power supply control circuit board circuit arranged inside the shell. The programmable direct-current voltage stabilizing power supply is characterized in that the power supply control circuit board circuit comprises a microcontroller, a current sensor, an analog-digital converter, a direct-current voltage stabilizing switch electric field, a field effect tube and a Max232 serial port module. By adopting the programmable direct-current voltage stabilizing power supply, automatic switching can be achieved according to programs, and in addition, current of a gyroscope can be monitored in real time.

Description

technical field [0001] The invention belongs to the technical field of DC stabilized power supplies, and relates to a programmable DC stabilized power supply, in particular to a programmable DC stabilized power supply for optical fiber gyroscope testing. Background technique [0002] The fiber optic gyroscope is a new generation of inertial instrument completely different from the traditional electromechanical gyroscope, which can be used in various military, civil and industrial fields such as aerospace, aviation, navigation, and weapons. Zero bias stability and zero bias repeatability are important static indicators of fiber optic gyroscopes and must-test items for fiber optic gyroscopes. At present, the zero-bias test of the fiber optic gyroscope is mainly in accordance with the requirements of GJB2426-2004. It needs to test 7 groups, each group takes 2 hours, and the power is turned off and cooled for 2 hours in the middle. Turning on and off the power supply and contro...
