| Abstract: | A data acquisition instrument is studied and implemented for the Fiber-optical -gyro Strapdown Inertial Navigation System (SINS). Based on the 80C196KC micro-controller unit (MCU), the data acquisition of the fiber-optical-gyros is implemented with the Quadruple Asynchronous Communication Element (QACE) chip TL16C554. And a 16-bit high precision AD676 is used for the data acquisition of the accelerometers. Both the hardware and software design of the data acquisition system is presented. The results show that the data acquisition instrument can meet the requirements for the SINS on data acquirement capability, and has good practicality. |
