Abstract

The present application relates to elevator technology, in particular to a method and device for detecting an elevator safety chain (10) and a computer-readable storage medium for implementing the method. According to one aspect of the present application, there is provided a device (20, 80) for detecting an elevator safety chain, comprising: an interface unit (810) coupled with the elevator safety chain and configured to output an operating signal having a first level when the elevator safety chain is in an ON state and an operating signal having a second level when the elevator safety chain is in an OFF state; and a processing unit (820), including: memory (821); a microcontroller (822) coupled with the interface unit; and a computer program (823) stored on the memory and running on the microcontroller, the running of the computer program causes: evaluating reliability of the elevator safety chain based on time domain characteristic of the operating signal output by the interface unit.
