摘要
首先分析了ADS1256的结构和主要性能,利用其多路差分输入的特点来采集捷联惯导系统中陀螺和加速度计的信号,采用DSP控制时序,将采集的结果通过高速串口送给RS232,然后再传给导航计算机进行导航解算,这样大大提高了导航运算的精度和速度,使惯导产品向小型化和高精度方向的发展成为可能。
The main performance and architecture of ADS1256 is introduced in this paper firstly, then the output signal of gyro and accelerator is acquired using its multi--differential input characteristic, DSP controls the timing sequence. Firstly the result is passed to RS232 through the serial port with high baud rate, then passed to navigation computer in order to navigation calculation, consequently the speed and accuracy of navigation calculation is highly promoted and it makes it possible to design the inertial navigation production of small size accurately
