Detailed description of the invention
Detailed narration is will make reference to below with reference to embodiments of the invention.
A kind of ribbon conveyer speed detection system based on RF identification, including two and above RFID tag 1, belt 2,3, two, cylinder and above reader 4, controller 5；Described RFID tag 1 is embedded on belt 2, and RFID tag 1 is fixing relative to the position of belt 2, it is possible to by different reader identification；Described belt 2 moves along with cylinder 3；The described distance between each two reader 4 is fixing, and RFID tag 1 is identified by described reader 4, and transmits a signal to controller 5；Controller 5 calculates the speed of ribbon conveyer according to the label signal recognized.
Described controller 5 is PLC.
A kind of principle based on the ribbon conveyer speed detection system of RF identification is the definition of speed, i.e. the ratio of distance and time.
Computational methods are mounted in first RFID tag 1 on belt 2, and the two or more readers 4 being determined along with belt 2 motion scan；Distance between first reader 4 and second reader 4 is L1, the distance between second reader 4 and the 3rd reader 4 is L2, the distance between the n-th reader 1 and (n+1)th reader 2 is Ln, and the distance Ln between each two reader 4 is fixing.
Pass through L1Value converse, in conjunction with the structure of ribbon conveyer, the distance S that belt 2 runs1It is certain, records T interval time that first RFID tag 1 is scanned through first reader 4 and second reader 411, at time T11The speed V that inner belt 2 is run11It is S1/T11.Installing n RFID tag 1 on belt 2, the interval time that second RFID tag 1 is scanned by first reader 4 and second reader 4 successively is T21, at T21The speed V that time inner belt 2 is run21It is S1/T21, the interval time that the n-th RFID tag 1 is scanned by first and second two reader 4 successively is Tn1, at Tn1The speed V that time inner belt 2 is runn1It is S1/Tn1。
Pass through L2Value converse, in conjunction with the structure of ribbon conveyer, the distance S that belt 2 runs2It is certain, records T interval time that first RFID tag 1 is scanned through second reader 4 and the 3rd reader 412, at time T12The speed V that inner belt 2 is run12It is S2/T12.Installing n RFID tag 1 on belt 2, second RFID tag 1 is T by second reader 4 and the 3rd interval time that reader 4 scans successively22, at T22The speed V that time inner belt 2 is run22It is S2/T22, the interval time that the n-th RFID tag 1 is scanned by second and the 3rd two reader 4 successively is Tn2, at Tn2The speed V that time inner belt 2 is runn2It is S2/Tn2。
Pass through LnValue converse, in conjunction with the structure of ribbon conveyer, the distance S that belt 2 runsnIt is certain, records T interval time that first RFID tag 1 is scanned through the n-th reader 4 and (n+1)th reader 41n, at time T1nThe speed V that inner belt 2 is run1nIt is Sn/T1n.Installing n RFID tag 1 on belt 2, the interval time that second RFID tag 1 is scanned by the n-th reader 4 and (n+1)th reader 4 successively is T2n, at T2nThe speed V that time inner belt 2 is run2nIt is S1/T21, the interval time that the n-th RFID tag 1 is scanned by first and second two reader 4 successively is Tnn, at TnnThe speed V that time inner belt 2 is runnnIt is Sn/Tnn。
