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 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。
Besides , the discussion of synchronous problem has also been brought forth . the data collection system includes the hardware and software design 基于usb2 . 0总线的数据采集系统主要包括数据采集系统的硬件实现部分和相应的windows驱动程序、底层固件程序及win32的实时性应用程序开发过程。
The reader can identify epc gen 2 tag . it widely used in vehicle access management etc personnel access management logistics control manufacture automation etc . data collection system 该读写器广泛应用于车辆门禁管理不停车自动收费etc人员门禁管理物流监控生产自动化管理等数据采集系统。
3 . design the hardware realization of the supervise system , it includes : under layer single control system , the communication system , the data collection system and the link to pc 现场总线的plc网络监控系统的硬件实现,主要包括,底层单机控制系统、通信系统、数据采集的实现方法、以及同上位机的链接。
In the course of data collection system , we first make certain sensor and build lan based advanced i / o modules as station from sixnet to collect datum , then give hardware wiring diagram 数据采集系统设计中,确定传感器的选型,通过采用先进的sixnet公司底层i / o站的设计实现底层数据采集,并给出了立井和风机的结构图和底层元器件接线图。
