Remote Image Acquisition and Synchronization System Based on FPGA and Bluetooth

  • 摘要: 针对核物理实验中高精度时间同步触发图像采集系统的要求,设计了一套基于FPGA和蓝牙的远程图像采集同步系统。该系统以FPGA作为主控制器,负责USB 接口通信、命令解析、蓝牙通信和同步控制等,触发信号延时精度可达10 ns;使用RS485 或TTL 标准以适应长距离触发和短距离触发,通过GigE 千兆网口实现远程图像数据采集。采用LabVIEW 开发了上位机图形化软件界面,基于蓝牙BLE4.0 协议,实现了基于手机APP的无线终端控制,完成了对相机延时时间、同步触发脉冲宽度、图像采集等命令的同步控制。

    A image acquisition and synchronization control system based on FPGA (Field Programmable Gate Array) and bluetooth is studied in this paper. FPGA as the main controller is responsible for USB (Universal Serial BUS) interface, command analyze, delay control, and trigger signal generation. Trigger signal can be RS485 or TTL. RS485 signals can be used for long-distance transmission without distortion while TTL is suitable for near field. The system's delay accuracy is reached to 10ns. It can be obtain images from GigE Ethernet port. Meanwhile,a PC graphical control software is developed by LabView. And based on the Bluetooth BLE4.0 protocol, a Android mobile phone APP is developed for wireless control.
