The MEMS inertial measurement unit consists of a three-axis
gyroscope, a three-axis acceleration meter, a three-axis
inclination angle, a temperature sensor, a signal processing board,
a structure and necessary software, and is used for measuring
three-axis angular rate, three-axis acceleration and three-axis
inclination angle of a carrier. And output that gyro, the loading
table and the inclination data aft error compensation (including
temperature compensation, installation misalignment angle
compensation, nonlinear compensation and the like) through an
RS-422 serial port according to an agreed communication protocol.
"IMU6-1y-x" in the drawing is the product code ". According to the
product naming rules of the company," y "in IMU6-1y-x can be" A ","
B "," C "or no letter to distinguish different performance index
requirements, and" X "can be" 1 "," 2 "." 3 "and" 4 "to distinguish
different product plus meter ranges. "XX-XXX" is the product
number.
IMU6-1y-x IMU is installed through 3 Φ4.4 through holes, and
installed with 3 M4 screws (with spring washer and flat washer).
When installing the connector, the plug shall be locked with the
socket and the cable shall be fixed. In the figureA,BIs the
installation datum plane of the inertia group.
It is recommended that the flatness of the mounting surface
opposite to the reference surface shall not be greater than 0.01
mm, the verticality shall not be greater than 0.02 mm, and the
surface roughness shall not exceed 0.8 μm.
