数据链作为图像制导导弹的指令及图像传输通道，在末制导过程中起着至关重要的作用。以某新型号红外图像制导导弹数据链测试方法为研究对象，LabWindows／CVI为开发平台，通过自主编程，设计并实现了一套数据链测试系统。使用串口服务器实现了串口控制，在CVI环境中应用异步定时器、多线程技术实现了多个高精度时钟，设计的测试软件能够实时检测识别数据链传输丢（错）帧数，并能模拟丢帧、指令数据长度错误、控制量错误、发送周期不稳等故障模式以检验数据链传输性能是否满足技术要求。某型制导弹数据链的验收测试过程及结果表明该系统具有功能较强、构建简易、定时精度高等特点。

Take the test method of the data link of a new infrared image guided missile for the study,a data link test system is designed and implemented by programming based on Lab Windows/CVI development platform.The designed test soft can detect and recognize lost frames and error frames in the data transmission in real time,and can simulate some fault patterns such as frame losing,instruction data length error,control amplitude error and data sending periodic instability in order to check whether the data transmission performance of the data link meets the design technical requirements.
