大数据量、高中断频率数据接收的软件设计

Software Design of High Interrupt-frequency and Mass Data Receiving

设计了一套满足机载测深激光雷达要求的高速、实时数据接收软件, 能够实现中断频率为1 000Hz的多路数据, 能以约16MB/s的速率实时接收并存储到计算机硬盘中。详细讨论程序设计方法，重点分析了高中断频率数据的实时、同步接收和存储的实现细节。

This paper bases on a lidar-data-acquirement system which needs transmit and store muti-channel data which interrupts the computer at a speed of 1kHz to the computer at a speed of 16MB approximately. This paper introduces how to write the software to control the real-time data receiving and saving synchronously.
