Abrégé
(EN)
A distributed POS (Position and Orientation System) sub-IMU (Inertial Measurement Unit) synchronous data acquisition system comprises a synchronous control/data receiving module based on FPGA (Field Programmable Gate Array), a high-speed asynchronous serial bus and a data acquisition/processing module based on ARM (advanced RISC machine), wherein the synchronous control/data receiving module based on FPGA realizes the control of time synchronization of a distributed POS system and receives data of a plurality of sub IMUs in real time; the high-speed asynchronous serial bus realizes communication between the master POS and sub IMUs at different measurement nodes; and the data acquisition/processing module based on ARM realizes parallel acquisition and real-time processing of the signal of a fiber-optic gyroscope, the signal of an accelerometer and the temperature signals of the gyroscope and the accelerometer. The distributed POS sub-IMU synchronous data acquisition system realizes real-time data acquisition of a plurality of sub IMUs of the distributed POS, reduces the size and power consumption of the sub IMUs, meets the requirement of miniaturization of the subsystem and simultaneously realizes time synchronization of the distributed POS system.
