摘要
在航天遥测系统中,为了提高传感器的噪声信号传输以及存储的稳定性和效率,设计了一种以FPGA为主控制核心的噪声信号采集压缩和存储系统,采集到的四路传感器噪声信号由ADS8365进行模数转换,然后由TMS320C6416芯片将转换后的数据进行压缩,并由K9WBG08U1M存储芯片对数据进行存储。经过多次的实际测试结果显示,系统的可靠性高,可以有效地提高噪声信号的传输及存储效率。
In the aerospace telemetry system,in order to improve the noise signal transmission and storage stability and efficiency of the sensor,a noise signal acquisition compression and storage system based on FPGA is designed.The four sensor noise signals collected by ADS8365 are designed.The analog-to-digital conversion is performed,and then the converted data is compressed by the TMS320C6416 chip,and the data are stored by the K9WBG08U1M memory chip.After many actual test results show that the system has high reliability and can effectively improve the transmission and storage efficiency of noise signals.
