<P>PROBLEM TO BE SOLVED: To provide a remote monitoring system for an elevator in which various types of noise having a risk of hindering direct communication using an interphone in an elevator car can be reduced to easily secure excellent communication quality. <P>SOLUTION: In the remote monitoring system for the elevator in which the interphone 2 in the elevator car 1 can communicate directly with a monitoring center 7 via a remote monitoring device 6, the noise collected by the interphone 2 is detected periodically by the remote monitoring device 6. The remote monitoring device 6 includes: a communication part 6a capable of transmitting and receiving a message to/from both the interphone 2 and the monitoring center 7; a noise data analysis part 6c for specifying the source of the noise collected by the interphone 2 and analyzing whether the volume thereof can be controlled or not; a noise data storage part 6b for storing the result analyzed by the noise data analysis part 6c; and a control determination part 6d capable of outputting a signal for controlling the source of the noise. When performing direct communication by using the interphone 2, and when the volume of the noise is determined to be larger than an allowable value, the remote monitoring device 6 transmits a control signal to a control panel 5 to suppress the volume thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT |
