The invention discloses a hemispherical resonator gyroscope vibration state monitoring system and monitoring method, and belongs to the technical field of hemispherical resonator gyroscope vibration state monitoring. The problem that vibration information is lost in an existing hemispherical resonator gyroscope vibration state monitoring mode is solved. According to the main technical scheme adopted by the method, a hemispherical resonator gyroscope vibration state monitoring system comprising a hemispherical resonator gyroscope header, a gyroscope control board card, a rotary table, a rotary table driver, a data acquisition card and a computer is established, and the rotary table is responsible for providing angular velocity input; the gyroscope control board card is responsible for resolving gyroscope vibration information and driving the harmonic oscillator to vibrate, the data acquisition card is responsible for acquiring a gyroscope vibration signal into the computer, and the computer is responsible for resolving each to-be-monitored quantity in real time, displaying and storing the to-be-monitored quantity and sending an instruction to the turntable driver to control the turntable. The method disclosed by the invention can be applied to monitoring the vibration state of the hemispherical resonator gyroscope.
Description
technical field [0001] The invention belongs to the technical field of hemispherical resonant gyroscope vibration state monitoring, and in particular relates to a hemispherical resonant gyroscope vibration state monitoring system and a monitoring method. Background technique [0002] Hemispherical Resonator Gyro (HRG) is a new type of vibrating gyroscope that appeared in the 1960s. It has the advantages of high precision, high reliability, long life and strong impact resistance. The one with the smallest weight and power consumption. Compared with other gyroscopes, the hemispherical resonant gyroscope has a simpler structure and is not easy to be damaged. There is basically no mechanical loss when the resonator vibrates in the vacuum enclosure, and it can still work normally for more than 15 minutes even in the case of a sudden power failure. Therefore, compared with other high-precision gyroscopes, hemispherical resonant gyroscopes are more durable and more suitable for ma...
