According to the current situation that inertial measuring unit(IMU) is detected with low measurement efficiency and large amount of labour, this article designs and develops an IMU intelligent measurement system based on dividing table indexing device. This system makes use of dividing table indexing device to provide reference angle positions, takes advantage of industrial computer to control dividing table indexing device, programmable DC power and IMU to work orderly and harmoniously. Besides, host-computer software can control the programmable DC power to supply electricity for IMU, and automatically send, collect, analyze and process measurement data to detect IMU intelligently, efficiently and accurately. The experiment result shows that 4 IMUs can be detected automatically at the same time, all detection data can be computed, displayed and saved. Moreover, this system has the features of high detection precision, more efficient, high level of intelligence, small amount of labor, and high performance-cost ratio. In addition, all functions in software interface can be operated through manual touch, which makes it convenient to operate.
