RFieldbus是一种全新的具有扩展的无线连接能力和传送TCP/IP数据包能力的无线PROFIBUS系统。为了评测这种有线无线复合系统的性能,首先在理论上对物理层到应用层间的各层的差错特性和修复机制做了分析,而后对数据交换周期,TCP/IP的吞吐量及丢包率等参数做了详细的讨论。基于RFC2544测试方法,进行了一系列的实验。对实验中所用的软硬件、测试过程在文中分别作了叙述。对测试结果的详细讨论表明,RFieldbus可以满足工业环境中的控制性能要求。
RFieldbus is a new wireless PROFIBUS system with extended wireless connectivity and the ability to transport TCP / IP packets. In order to evaluate the performance of this wired / wireless hybrid system, we first analyze the error characteristics and repair mechanisms of each layer from the physical layer to the application layer in theory, and then analyze the data exchange cycle, TCP / IP throughput and packet loss Rate and other parameters made a detailed discussion. Based on the RFC2544 test method, a series of experiments were carried out. The hardware and software used in the experiment, the test process were described in the text. A detailed discussion of the test results shows that RFieldbus meets the control performance requirements in industrial environments.
