The structure and the incorrect discharge status of three-axis laser gyro are introduced briefly.The necessity of status monitoring circuit is proposed.Based on the designed high voltage and current stability circuit,the sequence between current stability and status monitoring is controlled by adding an analog switch to each current stability branch of the high voltage power supply.The status monitoring is also realized by monitoring the voltages of the sampling resistances.Moreover,the realization of software and hardware of status monitoring circuit for three-axis laser gyro are introduced in detail.In the end,the circuit is tested,the ignition ratio of three-axis laser gyro is up to 100% in 5 seconds and long-term current stability exceeds1×10^-4.The feasibility and reliability of the circuit is validated.
