Abstract
Official abstract text for this publication.
Provided is a passenger-conveyor step-chain monitoring system capable of monitoring elongation of a step chain without adding a special device. The passenger-conveyor step-chain monitoring system includes a monitoring unit configured to monitor elongation of a step chain attached to a step of a passenger conveyor based on a result of detecting the step by a sensor provided to detect an absence of the step. With this configuration, it is possible to monitor elongation of the step chain without adding a special device.
First claim
Opening claim text (preview).
The invention claimed is: 1. A passenger-conveyor step-chain monitoring system comprising: processing circuitry configured to monitor elongation of a step chain attached to a step of a passenger conveyor based on a result of detecting the step by a sensor provided to detect an absence of the step, to store information about a monitoring result of elongation of the step chain every time monitor elongation of the step chain is monitored, and to predict a replacement period for replacing the step chain based on stored information about a plurality of monitoring results of elongation of the step chain, wherein the processing circuitry is further configured to monitor elongation of a step chain located on one side of the passenger conveyor based on a result of detecting a step by a pair of one-side sensors provided at upper and lower portions of the passenger conveyor on the one side of the passenger conveyor, and monitor elongation of a step chain located on another side of the passenger conveyor based on a result of detecting the step by a pair of other-side sensors provided at upper and lower portions of the passenger conveyor on the other side of the passenger conveyor. 2. The passenger-conveyor step-chain monitoring system according to claim 1 , wherein the processing circuitry is further configured to transmit information about the monitoring result of elongation of the step chain.
