【摘要】：96通道变形镜驱动器内含6个驱动模块,每个驱动模块含有16个输出通道,为了更加有效地管理控制这6个驱动模块,并实现与上位机、图像处理模块的交互通信,设计了变形镜驱动器控制电路。该电路包含了硬件设计和软件设计,其中硬件设计包含了电源设计、接口设计和FPGA设计,旨在实现高速向CPCI总线传输来自SPI接口的驱动矢量数据,同时把这些数据以适当的速度发给上位机。软件设计包括FPGA程序和NIOS系统程序设计,其中NIOS程序旨在实现上位机对上位机指令或数据的接收、处理和发送,以及对系统参数的配置以及驱动模块参数的保存等。结果表明,该电路不仅能够以200 f/s的速率正确接收并发送来自图像处理模块的驱动矢量数据,还能够正确收发来自上位机网口或者串口的控制指令,实现单通道与驱动矢量的切换、驱动矢量数据源的切换、单通道电压设置、放大器参数调试和保存以及通道数据读取、回传等功能,达到了预定的设计目标。
[Abstract]:The 96 channel deformable mirror driver contains 6 driving modules, and each drive module contains 16 output channels. In order to manage and control the 6 driving modules more effectively, and to realize the interactive communication with the host computer and image processing module, the 96 channel deformable mirror driver contains 16 output channels. The control circuit of deformable mirror driver is designed. The circuit includes hardware design and software design. The hardware design includes power supply design, interface design and FPGA design. The purpose of this circuit is to transmit the driving vector data from SPI interface to CPCI bus at high speed. At the same time, these data are sent to the upper computer at the appropriate speed. The software design includes FPGA program and NIOS system program design, in which the NIOS program aims to realize the receiving, processing and sending of the instructions or data, the configuration of system parameters and the preservation of the parameters of the driver module. The results show that the circuit can not only correctly receive and transmit the driving vector data from the image processing module at the speed of 200 f / s, but also send and receive the control instructions from the upper computer network port or serial port correctly. The functions of single channel and drive vector switching, driving vector data source switching, single channel voltage setting, amplifier parameter debugging and saving, channel data reading and retransmission are realized.
