基于FPGA的捷联惯组数据采集系统设计与实现

惯性器件性能的好坏直接决定了武器系统的性能，惯性器件的测试工作需要专门的脉冲采集系统来实现，本文介绍了一种基于FPGA的新型惯组脉冲采集系统，通过选用XC3S1000-4FGG676I芯片轻松实现了多路脉冲信号、交直流电压量以及温度传感器信号采集，抗干扰措施的采用有效地保证了该系统的稳定性和可靠性，经过大量的试验考核目前已经正式运用于捷联惯组的单元测试过程中。

Strap-down Inertial Navigation Design and Implementation of Data Acquisition System Based on FPGA

The performance of inertial device directly determines the performance of weapon system, testing work need inertial device special pulse acquisition system to realize, the traditional IMU pulse acquisition using 8253 programmable counter / timer to achieve, but due to various reasons, need to develop a new technology using the IMU pulse acquisition system to meet the current strapdown inertial measurement unit testing, this paper introduces a new type of inertial measurement unit pulse acquisition system based on FPGA, by using XC3S1000-4FGG676I chip can realize multi-channel pulse signal, AC and DC voltage and temperature sensor signal acquisition, the anti-interference measures effectively ensure the stability and reliability of the system, through the test of the has been formally applied to the strapdown inertial measurement unit testing process in group.
