WIPO Patent Application WO/2021/062903

A1

A safe operation method, system, and device for an elevator, a computer readable storage medium, and a safety function apparatus. When the safe operation method for an elevator is applied to an elevator main controller, said method comprises: detecting a first door zone signal and a second door zone signal; when it is detected that both the first door zone signal and the second door zone signal are door zone effective signals, generating a door sealing switch group turn-on instruction according to the door zone effective signals and an elevator operating state, and sending the door sealing switch group turn-on instruction to a safety function apparatus (42), so that the safety function apparatus (42) controls a door sealing switch group (423) to be connected to a door lock circuit in a short-circuit manner; and upon receipt of a door sealing feedback signal from the safety function apparatus (42), performing an advance door opening or re-leveling operation. In this way, the number of times of actions of door sealing switches is greatly reduced, improving the service life of related hardware.
