摘要
为了实现惯导系统对多种信号的测量要求,设计了一种基于FPGA的多模式硬件平台。设计了1路内部定时器,48路脉冲计数器,锁存器及64x32bit的FIFO,外加8路AD采集通道,共实现4通道惯导产品的速率及加速度及测温等多类型信号的测量。与传统单一信号测量设备相比,该设计具有较高的可靠性和稳定性,有很强的扩展性,提高了测量效率,降低了成本。
In order to achieve the requirement of inertial navigation system for measuring multiple signals,a multi-mode hardware platform based on FPGA is designed.Taking advantage of its flexibility,It has been designed to include 1-channel internal timer,48-channel pulse counter,latch with 4x32bit FIFO,and 8-channel AD acquisition channel.The Measurement of velocity and acceleration pulse signal and analog temperature measurement signal of four products has been realized.
