摘　　要：针对红外图像实时生成系统中帧图像数据传输的高实时性需求,提出了一种以反射内存为基础的红外图像数据实时传输方案,并给出了一种实时网络性能指标测试方法,基于该方法对反射内存网的实时指标进行了考核。实验表明:采用DMA数据读写模式、实时优先级的进程控制、非冗余传输模式,所提出的实时传输方案可满足红外图像数据传输的高实时性需求,同时,该方案具有模块化程度高,配置灵活,便于调试、扩充和升级等优点。Aiming at the real-time performance requirement of the frame data transmission in the real-time infrared image generation system, an infrared image data transmission scheme based on reflective memory network was proposed. A method to test the performance of real-time network was given. The performance of the reflective memory was evaluated based on the method. Tests show that the real-time requirement of the infrared data transmission can be fulfilled by the scheme under DMA R/W mode, real-time PRI mode and transmission without redundant mode. And at the same time, the scheme proposed in this paper shows its advantages in high modulafization, flexible configuration, easily debugging, expanding and updating.
