基于USB的现场总线实时网络数据采集器

Fieldbus Real-time Network Data Collection Based on USB

针对目前基于PC机终端监控的现场总线实时网络数据采集系统,无法脱离PC机独立工作的缺点,以基于热浸镀锌工艺的RS-485总线网络为例,简要介绍了现场总线实时网络的结构和工作原理;以CY7C68013为核心设计了基于USB的现场总线实时网络数据采集器。该采集器能够脱离PC机独立完成实时采集数据和实时监控总线网络的任务。

In view of the shortcoming that present fieldbus real-time network data collection systems based on PC machine ter- minal monitoring, are unable to work independently without the PC machine. Taking RS -485 bus network based on the pot galva- nizing works for example, this paper briefly introduced the fieldbus real-time network＇s structure and principle. Using the CY7C68013 as the core, this paper designed a fieldbus real-time network data collection. The collection can independently complete the task of collecting the data and monitoring the bus network in real-time, without the PC machine.
