【Abstract】 Considering the flexibility,stability,and low error rate requirements of speed measurement,a wireless speed measurement system based on ZigBee 2006 protocol stack model frame is designed and realized.Some current methods of speed measurement are briefly analyzed and compared,a positioning structure is established centering on CC2431 chip,and ZigBee 2006 is cut and migrated.More attention is paid to selection of chip,thoughts for software design,principles and methods of positioning and speed measurement,and error analysis.Speed measurement and information interaction between embedded systems is completed.Simulation results indicate that the system is designed so reasonable that it can satisfy flexibility,stability,low error rate commands of speed measurement.更多还原
