为了对四象限探测器输出的四路信号进行同步采集传输
本文设计了一套高分辨率、高速率的同步数据采集传输系统。该系统首先以FPGA芯片EP1C12Q240为核心
控制模数转换芯片ADS1274采集数据
数据经过片内FIFO缓存
然后按Camera Link协议将数据打包为3240大小的图像
图像经Camera Link接口传输到PC机
最后使用图像采集卡采集图像数据
并利用MATLAB编写软件实现图像解码与存储。实验结果表明:该系统实现了分辨率为24 bit、采样速率为100 kHz的4通道同步数据采集
其有效分辨率可达18.79 bit
数据传输稳定可靠。满足了数据采集系统高分辨率、高速率的需求
并且该方案也可方便地移植到其他应用中
具有较好的可扩展性。
In order to acquire synchronously and transfer four channels signal outputted by quadrant detector
a high-resolution
high-rate synchronous data acquisition and transmission system is designed. Firstly
an FPGA chip named EP1C12Q240 is selected as the core to control the acquisition of AD (ADS1274) and buffer data into FIFO on chip. Then the data is packaged into images consist of 3240 pixels according to Camera Link protocol
and transferred to PC via Camera Link interface. Finally
the images are acquired by image acquisition
decoded using software programmed with MATLAB
and stored in PC. Experimental results show that the system
whose effective resolution is up to 18.79 bit
achieves a resolution of 24 bit
sampling rate of 100 kHz and 4-channel synchronous data acquisition
and can transfer data stably and reliably. The system meets the requirements of high resolution
high sample rate and synchronous acquisition. In addition
it has good scalability and could be ported to other applications.
