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.
