System and method for operation management of conveyor belt

A system for operation management of a conveyor belt, the system comprising:

• a plurality of IC tags of a passive type to be installed at a conveyor belt;
• a detector configured to wirelessly communicate with the IC tags without contacting the conveyor belt;
• and
• a computation device communicably connected to the detector;
• the detector receiving return radio waves returned from the IC tags installed at the conveyor belt mounted in a conveyor device in response to transmission radio waves transmitted from the detector toward the IC tags,
• the computation device calculating a running speed of the conveyor belt based on reception times of the return radio waves by the detector disposed at at least one detection position of the conveyor device,
• an operational state of the conveyor belt being determined based on a change over time in the running speed calculated,
• the detector disposed at the detection position that is identical receives the return radio waves from a plurality of the IC tags each disposed at positions spaced apart in a longitudinal direction of the conveyor belt,
• the running speed is calculated based on the reception time of the return radio wave from each of the IC tags by the detector and a separation distance between the IC tags in the longitudinal direction of the conveyor belt, and
• wherein if the detector disposed at the detection position receives, when the IC tag that is identical passes through a detection position of the detector, the return radio wave from the IC tag that is identical multiple times while the IC tag passes once, time of receiving the return radio wave having a highest received signal strength indicator of the return radio waves received multiple times is adopted as the reception time by the detector disposed at the detection position.

• the detector disposed at the detection position that is identical sequentially receives the return radio wave from the IC tag that is identical every time the conveyor belt laps, and
• the running speed is calculated based on reception time of the return radio wave sequentially received by the detector and a belt length of the conveyor belt, and
• wherein if the detector disposed at the detection position receives, when the IC tag that is identical passes through a detection position of the detector, the return radio wave from the IC tag that is identical multiple times while the IC tag passes once, time of receiving the return radio wave having a highest received signal strength indicator of the return radio waves received multiple times is adopted as the reception time by the detector disposed at the detection position.
