实现了基于Nios Ⅱ软核处理器的通信控制的设计，以Nios Ⅱ软核作为中央处理器，利用FPGA的逻辑资源构成片上可编程系统（SoPC）来实现光电设备的通信控制功能。设计实现了通过RS 422串口和通用IO口来实现对光电设备中各传感器的通信控制和信息传递功能。该设计已成功应用于某光电侦察设备，试验证明，该通信控制性能稳定，功能完善，在光电设备多传感器的控制领域有着广泛的应用前景。%The communication control based on Nios Ⅱ soft-core processor is designed,which uses Nios Ⅱ soft-core as the CPU. The communication control function of the photoelectric equipment is realized by SoPC built by the logic resource in FPGA. The communication control function and information transmission function of sensors in photoelectric equipment is realized by RS 422 serial port and GPIO. The design has already been applied to one photoelectric reconnaissance equipment. Experiment shows that the communication control has steady performance and comprehensive features. It has very broad application prospects in control field of photoelectric equipment with multiple sensors.
