摘要
DeviceNet是一种低成本、高性能、应用广泛的设备级现场总线 .本文对它的实时性进行了深入分析 ,推导出位时间、传输时延和采样点等参数之间的对应关系 .在此基础上对其缺点进行了改进 ,增加了跳变沿 ,并与数据压缩技术相结合 ,提高了总线的总体性能 .仿真结果表明了这种方法的有效性 .
The DeviceNet is a low-price and high-performance fieldbus. It has been applied in lots of fields. The real-time performance of DeviceNet has been analyzed deeply. Based on the analysis, we have deduced the relation of bit time, transmission delay and sample time. By means of voltage jump and data compression, the performance of the network has been increased. Simulation results show the effectiveness of the proposed method.
