多站联合测控中USB跟踪链路快速切换的实现

介绍了统一S频段(USB)测控设备跟踪链路切换的原理,针对多站联合测控中手动切换链路效率低的不足,为满足任务高难度、严要求的需要,缩短切换时间,提高切换准确性,提出以宏命令方式进行链路切换操作,应急状态下直接调用宏文件的方法,并在C#语言和.NET环境下采用用户数据报协议(UDP)实现快速切换,较原手动切换方法速度提高了约4倍.

Realization of USB Downlink Converters Fast Switching in Multistation Joint Measurement and Control

The principle of TT&C equipment to track links switching of unified S-band(USB) system is introduced.For the deficiency of low efficiency of manually-switching in multistation joint measurement and control, and to meet the strict requirements of task ,effectively reduce the sw itching time, improve the switching accuracy,a scheme is proposed in which the s withching operation is performed by the macro command, and the macro file is dir ectly invoked under emergency situation. Fast switching with UDP(User Data Proto col) in C# and .NET is achieved and the switching speed with this method is about 4 times than that with traditional mannual switching method.
