| 摘要: |
| 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。 |

| Abstract: |
| 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. |
