因此，变革传统的“光-电-光”信息交换方式，在网络节点上实施全光交换和全光信号处理是本世纪以来的全球研究热点，也是当务之急。
Therefore it is a world-wide hot topic and urgent affair to implement all-optical switching and all-optical signal processing in optical network nodes since the beginning of this century.
本系统采用网络扩展方案，单节点主要由振动数据采集、传输和实时信号处理单元组成。
This system adopts net expand scheme. Single unit includes vibration data collection, transmission and Real-time signal processor.
该控制器不仅可实现信号的采集、处理、显示，还可通过CAN总线实现不同节点间信号的传输。
The controller can realize not only the collection, processing and display of the signal, but also the transmission of signals between different nodes through can bus.
