| titleOfInvention | Driving and detecting device of micro-mechanical single-vibrator three-axis gyroscope |
| abstract | The invention discloses a driving and detecting device of a micro-mechanical single-vibrator three-axis gyroscope, which comprises a single-vibrator three-axis gyroscope, a driving module and a detecting module, wherein the driving module, the detecting module and the gyroscope are electrically connected, a driving electrode (4-7) and a vibrator (1) of the gyroscope form an x-axis angular vibration resonator (xResonator) and a y-axis angular vibration resonator (yResonator), the driving module is connected with the driving electrode (4-7) and the vibrator (1) of the gyroscope, the driving module comprises two loops, the first loop is used for driving the x-axis angular vibration resonator (xResonator) to perform fixed-frequency and fixed-amplitude vibration, the second loop is used for driving the y-axis angular vibration resonator (yResonator) to perform fixed-frequency and fixed-amplitude vibration, and the detecting module is used for detecting the angular speed output quantity of the gyroscope. The invention adopts a single-vibrator three-axis structure, can realize the compact structure of the gyroscope, has small volume and high detection precision and reduces the manufacturing cost of the gyroscope. |
