ELEVATOR INSTALLATION WITH SAFETY CONTROL SYSTEM WITH "MASTER-SLAVE" HIERARCHY Russian patent published in 2019 - IPC B66B1/34 B66B5/00 

FIELD: lifting devices.

SUBSTANCE: elevator installation (1) is proposed, which comprises drive (3), cabin (5), safety functional components (9a-p) for creation of safety functions in various positions inside elevator unit (1), safety control system (11) for monitoring of all functional safety components (9a-p). Safety control system (11) has several safety control units (13) having data or signal input interface (21), some of safety control system (11) monitoring units (13) are connected to each other by communication channels (15). Safety control system (11) safety control units (13) are organized in the form of "master-slave" hierarchy, besides, security control unit (13e) is made in the form of master unit, and at least one safety control unit (13a-d) is in form of a slave unit. Slave unit (13a-d) has unit (20) for processing data or signals into control signals and interface (22) for outputting control signals to the corresponding safety control unit (13), an activated safety functional component (9a-p), which is configured to actively influence the current operational state inside elevator installation (1).

EFFECT: higher safety is achieved.
