| 摘 要： | 在数字无线遥测地震台网中，用异步采样原理研制的多制式复分接设备，借助数字微波通道的大容量，可以解决不同制式、不同速率、不同接口标准数据流的复分接问题。同时，利用数字锁相环原理来降低异步采样带来的相位抖动，该设备在三峡数字遥测地震台网中首次应用，即获得成功。

| Abstract: | In digital seismic tele-metering network,by taking advantage of the huge tolerance of micro-wave digital channel,the multi-track division equipment,which is developed on the basic of asynchronous sampling principle,can resolve problems met in dividing multiple data stream of different transmission speed,different system and different in terface protocol.Additionally,by means of digital phase-locked technique,this equipment will weaken the phase fluctuation aroued by asynchronous sampling.During its first service in the Digital Seismic Tele-metering Network of Three-Gorge,this equipment perform very well. |
