| 摘 要： | 提出一种基于FPGA的空间电场信号数据采集与处理系统的设计方案,FPGA为主控制器控制A/D采样和同步422发送。X,Y,Z三个方向的空间电场信号经过信号处理和A/D采样,在FPGA片内滤波划分为不同的频段,通过同步422接口发送到后续设备。该系统性能可靠稳定,致力于应用在探空火箭有效载荷——箭载电场仪上,对其他电场信号采集与处理系统也有一定的应用价值。

| Abstract: | This paper presents a design scheme of space electrical signal acquisition system based on FPGA.FPGA is the main controller which controls the A/D sampling and the synchronized 422 sending.Space electrical signals in X,Y and Z directions will be sent to FPGA where signals are divided into different frequency channels by filters after signals are processed and A/D sampling.The system with the performance of reliability and stablity is applied in the sounding rocket payload,that is electrical field meter installed on satellite,which has a application value for other electrical signal acquisition and processing system. |
