MEMS gyro and accelerometer module package

摘要

The present invention relates to a multi-purpose MEMS sensor module package equipped with a gyro and an accelerometer, and an accelerometer sensor unit 10 provided with a three-axis accelerometer separately or integrally; An angular velocity sensor unit 20 provided with a three-axis accelerometer separately or integrally; A data acquisition circuit 30 for receiving the detection signals from the acceleration sensor unit 10 and the angular velocity sensor unit 20 to generate digital data; A triggering unit 40 capable of adjusting a triggering level through the interface unit 90; Clock (time) of the discretized acceleration data (Ax'_i, Ay'_i, Az'_i), and the discretized angular velocity data (Qx_i, Qy_i, Qz_i) for a certain period of time (ΔT) passing through the triggering unit 40 ) Blocking and storing the memory 50 together with the synchronization identifier; By reading the data block stored in the memory 50, angular velocity data is integrated to obtain _{representative values of} angular displacement (Rx_i _{representative value} , Ry_i _{representative value} , Rz_i _{representative value} ) for each section, integral values of acceleration, or each of the sections A microcontrol unit that calculates coordinate coordinate reference acceleration (Ax_i, Ay_i, Az_i) and reference coordinate velocity (Vx_i, Vy_i, Vz_i) based on the displacement representative values (Rx_i _{representative value} , Ry_i _{representative value} , Rz_i _{representative value} ). (60) and; Includes a wireless transmission / reception unit 80 for wirelessly transmitting the reference coordinate acceleration (Ax_i, Ay_i, Az_i), the reference coordinate velocity (Vx_i, Vy_i, Vz_i) calculated by the microcontrol unit 60 to the external device. It relates to a multi-purpose MEMS sensor module package equipped with a gyro and accelerometer, characterized in that configured by.
