为满足高能X射线成像装置对并行数据实时采集以及远距离传输的要求,开发了一套嵌入式并行数据采集与网络传输系统。该系统用FPGA实现多通道并行数据的实时采集,用ARM完成了数据的缓存以及基于TCP协议的以太网数据传输。此系统已成功应用于多台高能X射线成像装置中,运行稳定。
In order to acquire parallel data in real-time and transmit data for long distance in the high energy X ray imaging device, an embedded system which acquire data in parallel and transmit data using Ethernet is designed. In this system, FPGA is used to realize the parallel data acquisition in real time, and ARM is designed to buffer data, and transmit data using TCP protocol. This system has already be applied to some high energy X ray imaging devices, and works well.
