着重介绍了振动检测单元的硬件实现，基于有限脉冲响应（FIR）数字滤波与快速傅里叶变换（FFT）的实时数据处理过程，以及基于用户数据报协议（UDP）的数据传输过程。
The paper mainly introduces the hardware implement of inspection unit for vibration, real-time data process on FIR and FFT, and data transmitting process on UDP.
因此为了对大量数据的实时响应，建立了一个基于RS-485和现场总线PROFIBUS技术的监控和数据传输系统。
Therefore, according to real-time response of bulk data, the framework of the data collection system is presented on the basis of RS-485 and fieldbus PROFIBUS control and communication.
