Micro inertial sensors , small size , light weight , low cost , low power consumption and high reliability , easy to achieve digitization and intelligent prominent advantage of access to a wide range of applications since its birth . Strapdown inertial navigation system itself has distinctive features , the use of micro - sensor device SINS advantages become more prominent . The background of practical engineering , to complete micro inertial integrated system of hardware and software design . The paper first introduces the structure and working principle of micro inertial integrated system , the theoretical basis of the system design , the overall design . This article focuses on the completion of the signal acquisition circuitry of the system hardware and software design , signal acquisition circuit hardware is divided into the following sections: low- accuracy gyro and accelerometer data acquisition and processing circuit , temperature data acquisition circuit , external communications interface circuits , and guide The program load circuit. Assembly language and C language to TMS320VC33 on the basis of the system hardware circuit design as a tool to prepare the guide reproduced BOOT file data transmission control strapdown algorithm implemented in software . According to the characteristics of micro inertial integrated system , the use of the new A / D chip interrupt data capture multiple solver to timing data , using a FPGA chip to achieve all of the peripheral circuit design , this method of hardware design software , the design is simple and flexible , the system is compact , with innovative . Reliable system debugging and testing process , system hardware and software work , multi-channel signal acquisition , and laid a good foundation for the practical application of engineering .
