Title: Design of MIMU Structure and Carrier 3D Display Software
Abstract:
In recent years, with the development of MEMS (Micro-Electro-Mechanical Systems)
and inertial technology, the attitude and heading reference system (AHRS) built by
MEMS inertial sensors becomes research focus of domestic and foreign scholars. It
has the features of low price, small size, light weight, high integration and high
reliability and has a very broad application prospects in aviation, aerospace,
automotive, communications and military fields.
Structural design of the MIMU (Miniature Inertial Measurement Unit) was studied in
the paper. Two design schemes were reported, folding pyramidal structure, as well as
six side body structure, to which a finite element analysis was conducted to verify the
availability of the structure. The three-dimensional AHRS display software received
attitude angle information through the serial port and displayed the information
through three-dimensional graphics after hexadecimal conversion. Finally, the
software was tested to prove that it was effective and available.
