Abstract (en)
[origin: WO03024856A1] The invention concerns an elevator system (10) comprising an elevator car (12) mobile in an elevator cage by means of a driving unit (14), a control (16) for controlling the driving unit (14), a data bus (22) connected to the control (16), elevator doors (11) for closing the elevator cage, locking devices (18) for locking the elevator doors (11) on the cage side and locking sensors (20) for monitoring the position of the locking devices (20). The locking sensors (20) are connected to the control (16) via the data bus (22). The locking sensors (20) are automatically queried by the control (16) via the data bus (22) iteratively at short intervals so that communication interruptions or transmission errors during transmissions via the data bus can be detected. To test the function of the locking sensors (20) and the bus interfaces, the state of the locking sensors (20) is automatically queried at long intervals iteratively in conditions of closed elevator doors and open elevator doors, then made available to the control (14) via the data bus (22).
