Embodiment Construction
[0023] figure 2 It is a logical block diagram of the first preferred embodiment of the present invention. Such as figure 2 As shown, the present invention is an angular rate and angle gyroscope, including a power supply voltage stabilizing circuit S4 for providing each unit with a voltage of 5.5 volts or 3.3 volts, an A / D conversion unit S2, and a micromechanical gyro unit S1, a micromechanical gyroscope Unit S1 is an electronic gyroscope with small size and fast calculation speed. The angular rate analog signal induced by the micromechanical gyroscope unit S1 is converted into a digital signal output by the A / D conversion unit S2. The digital signal input is used to convert the measured The angular rate is solved as the CPU calculation unit S3 of the angle.
[0024] image 3 It is a structural block diagram of the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the output signal of the CPU computing uni...

The invention relates to an angular rate and angle gyro including a power regulated circuit which provides 5.5V or 3.3V voltage to each unit, an A / D transition unit and a micro-mechanical gyro unit. A / D transition unit transfers angular rate analog signal inducted by gyro to digital signal, which inputs into CPU calculating unit used to measure angular rate and resolve angle. The system adopts micro-electromechanical systems technology to measure angular rate, which has merits of small capacity, low cost, quick response and low power consumption etc. The invention can realizes uniaxial, biaxial or triaxial angular rate measuring and resolve uniaxial, biaxial or triaxial angle simultaneously, which simplifies disposing strength of back grade system and intensifies response time of the whole system.
Description
technical field [0001] The invention relates to a gyroscope, in particular to a gyroscope for measuring three-axis angular rate and angle, which is applicable to platforms, motion control systems, control of ships and vehicles, inertial guidance and navigation, angular rate and angle measurement of attitude and heading reference systems , belonging to the field of sensors. Background technique [0002] At present, the sensors for measuring angular rate or measuring angle are separated, and only one kind of measurement can be completed, and traditional sensors for measuring angular rate or angle generally use sensors such as mechanical gyroscopes or fiber optic gyroscopes, which are bulky , slow measurement speed, high power consumption, expensive, troublesome maintenance. [0003] figure 1 It is a circuit diagram of a power supply regulator for powering each chip in a traditional gyroscope. Such as figure 1 As shown, what U1 uses is a switching power supply chip LT1933, ...
