Abstract

PURPOSE: To rapidly rescue passengers in an elevator cage by automatically detecting the abnormality in the cage by the variation of the noise in the cage immediately after the cage door is closed.
CONSTITUTION: The noise output from a noise meter 3 is applied to a mean noise calculator 4, which thereupon calculates the mean noise in certain time and stores it. Contact 2a is opened after the certain time limit, while contact 2b is closed after the time limit. Thus, the noise output is applied to a comparison output generator 5, which thereupon compares it with the mean noise stored in the calculator 4. If the noise output generated from the noise meter 3 is abnormally large in the difference and ratio from the mean noise due to scream, cry, etc. at this time, a detection output is produced from the generator 5, and amplified by an amplifier 6 and supplied to an output relay 7.
