智能传感器信息流的图形化仿真方法
Information flow graphical simulation methods for smart sensors
摘要
Abstract
The overall performance of a smart sensor could be effectively predict and assess through simulation and analysis within its function architecture, signal flow direction, network transmission etc at the design stage. This paper used virtual instrument LabVIEW built a smart sensor graphical emulation model. The hardware architecture, the signal flow direction and the network transmission of the model were comprehensive simulation and a-nalysis with the performance evaluation indicators of the average data transfer rate v, average transmission delay time tie and packet loss rate. Results show that, The higher the sampling rate of the transmitter, the BW the greater; the STIM CPU-digit increases, the BW increases; dual-channel simultaneous read and write has better performance than single-channel; the buffer increases the BW decreases; the NCAP CPU-digit higher the BW bigger; the BW increases in priority transmission mode.关键词
