| 摘 要： | PROFIBUS现场总线协议的实时性是评价其性能的关键因素，因此，如何研究和计算实时性能参数显得尤为重要. 针对这一问题，在对PROFIBUS总线存取协议深入分析的基础上，设计了基于PROFIBUS-DP通信性能测试平台. 通过测试平台分析和计算了包信息率、传输效率、网络平均利用率、网络吞吐量、传输延迟和令牌循环时间等实时性能参数，并给出了总线循环时间与主站个数及报文数量之间的关系之间的关系，从而定性定量分析了PROFIBUS-DP现场总线的实时性能.

| Abstract: | The real-time parameter is a key point in PROFIBUS field bus protocol''s performance evaluation, so how to analyze and count its communication parameter is of great importance. According to the problem, based on the detailed analysis of PROFIBUS field bus access protocol, a type of testing platform for PROFIBUS-DP communication performance is designed. Through this testing platform, these real-time performance parameters are analyzed including bag information rate, transmission efficiency, network average utilization, network throughput, transmission delay, token rotation time etc., and the relationship between bus cycle time and master station or packets number are also given out. So, the real- time performance of PROFIBUS-DP is quantitativly analyzed. |
