MONITORING DEVICE OF ELEVATOR

摘要

PROBLEM TO BE SOLVED: To provide a monitoring device of an elevator which can further correctly detect failure in a car.

SOLUTION: This monitoring device of an elevator includes: a radio wave absorption sheet 2 for preventing radio waves from entering into a car 1; a radio wave detection device 3 for detecting radio waves in the car 1; and a failure detection device 5 for detecting failure in the car 1 based on a detection signal of the radio wave detection device 3 and a control signal transmitted from a control device 6 for controlling the car 1. The failure detection device 5 is configured to transmit, to the control device 6, a running door opening signal for moving the car 1 to another floor to open a doorway.
