AN Zhi-yong, LI Ying-hong, XU Yong-qiang, et al. Realization of measurement in certain type aeromotor’ retational speed[J]. 2006, (1): 36-38. DOI: 10.13873/j.1000-97872006.01.013.
For improving the measuring accuracy and reliability
the intelligence checking and controlling system of aeromotor is designed with AT89C51 single chip processor.Monitor of the aeromotor’s working state on line is accomplished through collection
operation
and analysis of the rotational speed.The system uses the way of frequency measuring of many circles and synchronization to measure the rotational speed.The results show that it avoids the±1 error coming from the traditional method and improves the measuring accuracy.This system has the characteristic of small volume
low cost
high accuracy and etc.It can be used widely in future.
