一维前向散射滴谱探测器的信号处理系统设计

A DESIGNED SIGNALS PROCESSING SYSTEM FOR THE 1D FSSP-100

介绍一维前向散射云滴谱探测器(FSSP—100)的信号处理系统电路板的软硬件设计方案。该系统由专用单片机、8255、液晶显示器等器件构成。它对云滴谱探测器输出信号进行采集,并按要求处理成滴谱数据。此外,还可通过该处理板控制滴谱探测器的量程。

A soft-and hardware scheme for a circuit board is presented for the signals processing system of a 1D FSSP(forward scattering cloud-droplet spectrum prober)-100.The system is composed mainly of a special single-board microcomputer,parallel interface element 8255 and a liquid crystal indicator,and responsible for collecting FSSP signals and processing them in a de- signed way.Further,the range of the device can be regulated through the processing borad.
