基于LonWorks的客运列车数据采集系统

Data Acquisition System of the Passenger Train Based on LonWorks

利用FPGA器件完成底层数据采集及LonWorks总线作为传输介质,采用OPC server实现LON网络与上位机的数据传输,运用RSView32组态软件开发了一套LonWorks的数据动态监视平台,构建了客运列车的数据采集系统;整个系统克服传统数据采集方案中的缺点,达到了实时、快速、易于扩展及动态监视的目的,接口更易于实现,减少了开发成本和缩短了开发周期,具有一定的通用性和实用价值。

The system uses the FPGA hardware to finish data acquisition,adopts the LonWorks bus as the transmission medium, and uses OPC server to realize the data transmission between the LON network and PC, uses RSView32 configuration software to build the data monitor platforms of the LON network, and then constructs the data acquiring system of the railway passenger cars. The system overcomes the shortcoming of the traditional data acquiring scheme,and achieves the purposes of real-time, rapid, flexible, and easy expansion and dynamic monitoring. With the interface easy to achieve, the system reduces developing cost, shortens the developing cycle, and has a good popularity and practical value.
