FIELD: mechanical engineering: lifts and elevators.
SUBSTANCE: proposed lift system is provided with lift cabin installed for travel in lift well. Drive unit and its control device are provided. Lift well doors are furnished with interlocks for locking from side of well. Position of interlocks is checked by interlock pickups. Data bus is provided through which interlock pickups are connected with control device. Interlock pickups are polled automatically in repeated manner at short time intervals by control device through data bus to detect interruption of communication or errors at transmission of data through data bus. Operation of interlock pickup and bus interfaces is checked in repeated manner at longer time intervals by automatic polling of condition of interlock pickup at open and closed door of lift well and transmission of data through data bys to control device.
EFFECT: reduced cost of system as compared with known ones at provision of high operating safety.
