摘要
在某弹载遥测项目开发中,为了实现A/D转换芯片ADS8686S对多路传感器信号的采集,设计了一种基于FPGA的传感器信号采样控制器。首先简单介绍了ADS8686S的指标参数,其次分析了芯片的并行接口控制时序,在此基础上,重点讨论了控制器的软件设计方案。在保证采样精度和速度的同时,控制器可对ADS8686S的工作状态进行实时监测,提高了采样的可靠性。控制器已在多次遥测试验中得到验证。
In the development of a ballistic telemetry project,in order to realize the acquisition of multiple sensor signals by the A/D converter,ADS8686S,a FPGA⁃based sensor signal sampling controller is designed.Firstly,the characteristics of the ADS8686S are briefly introduced,and then the parallel interface principle of the chip is analyzed,and on this basis,the software design scheme of the controller is discussed.The controller can monitor the operating status of the ADS8686S in real time while en⁃suring sampling accuracy and speed,which can improve the sampling reliability.The controller has been validated in multiple te⁃lemetry tests.
