摘要
航空发动机控制所需测量的模拟量信号数量越来越多,传统的单片机设计已无法满足参数采集的需要。针对上述问题,设计了一种基于FPGA的模拟量参数采集系统,使用FPGA控制多路选择器和A/D转换芯片进行多路模拟量参数采集。对多路选择器切换速率性能受限的应用场景,提出了优化FPGA切换控制的方法,通过验证能够达到模拟量参数采集的实时性需求及多路选择器器件的性能要求。
The number of analog signals required for aero-engine control is increasing,and the traditional single-chip microcomputer design can no longer meet the needs of parameter acquisition.To solve the above problems,an FPGA-based analog parameter acquisition system is designed,and the FPGA controls multiplex selector and A/D conversion chip to acquire multiplex analog parameters.For the application scenario where the switching rate performance of multiplex selectors is limited,a method to optimize FPGA switching control is proposed,and the real-time requirements of analog parameter acquisition and the performance requirements of multiplex selector devices are met through verification.
