| Abstract: | In order to meet the demand of data acquisition of vibrating-string gyroscope,a method of measuring frequency by using multi-period synchronous frequency measurement and differential method is proposed.The measurement accuracy of gyroscope is analyzed theoretically,and the specific hardware circuit of frequency measurement module is presented,which includes signal conditioning circuit,single chip computer control circuit,A/D conversion circuit,display circuit and so on.The angular velocity is solved by using AT89C52 single chip computer.The simulation results show that the whole hardware circuit of the signal detection system is simple,easy to use,low in cost,and has a good application prospect in the field of inertial navigation. |
