<p><P>PROBLEM TO BE SOLVED: To provide a carrier operation measurement system for easily measuring the movement position and moving speed of a carrier at a low cost with simple constitution. <P>SOLUTION: The carrier operation measurement system 1 includes: a position tag 2 installed in a carrier operation area, a tag read unit 3 installed on the carrier 10 to read position information of the position tag 2, a wheel tag 4 which is installed on a wheel 11 and detected by the tag read unit 3, a shield unit 5 which is fixed to the carrier 10 and shields an orbit of the wheel tag 4 to prevent the wheel tag 4 from being continuously detected by the tag read unit 3, a transmission unit 6 which transmits position information from the position tag 2 and detection information of the wheel tag 4 output from the tag read unit 3 as operation information of the carrier 10 to the outside of the carrier 10, a reception unit 7 which receives the information transmitted from the transmission unit 6, an arithmetic unit 8 which calculates the moving speed of the carrier 10 based upon a frequency of appearance of the received detection information, and a recording unit 9 which records the operation information including the calculation result. The tag read unit 3 is used for both the tags 2 and 4. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
