| 总结: | This project is to implement a simple measurement of velocity for a flowing
object in a conveying pipe. The objective is to utilize the cross correlation method to
obtain the velocity of that object by using infrared sensor. The measurements circuit
consists of sensors, signal control circuit and data acquisition system. Sensors fixtures
are designed based on parallel beam projection technique. To measure velocity, two
arrays of sensors are placed upstream and downstream on the pipe. The output from both
sensors is cross-correlated. The peak of the cross correlation graph represented the time
for the object to move from upstream to downstream. The velocity is obtained by
dividing the time and the distance between upstream and downstream. Prototype circuits
will be implemented which involved design and implement of signal control circuit, jig
and fixture design or fabrication. For data processing method, Visual Basic 6.0 is used
for software algorithms on cross correlation calculation. The data is collected using data
acquisition system and it was an offline process. |
