    摘要： An elevator system (201) comprising a hoistway (217) comprising landing (225A-225C), which comprises a landing door (227A-227C), an elevator car (203), comprising an elevator car door (229), arranged to move within the hoistway (217), a first safety switch (231; 233) configured to indicate a potential hazard in the elevator system (201) and a controller (215). The controller (215) is configured, when the first safety switch (231; 233) is triggered, to stop movement of the elevator car (203) and determine whether the elevator car (203) is located anywhere within an unlocking zone (253) in the hoistway. The controller is further configured, if it is determined that the elevator car (203) is located anywhere in the unlocking zone (253), to allow the elevator car door (229) and landing door (227A-227C) to be opened.

    摘要： An elevator system (2) comprises: a hoistway (14) extending between a plurality of landing zones (6, 8, 9); at least one elevator car (12) configured for moving along the hoistway (14); at least one positional sensor (24, 26, 63, 83, 93) arranged at a defined position within the hoistway (14); a speed and/or acceleration sensor (25), which is configured for determining current speed and/or acceleration information of the at least one elevator car (12) within the hoistway (14); and an elevator controller (28), which is configured for: A) calculating current positional information of the at least one elevator car (12) within the hoistway (14) from the speed and/or acceleration information; B) checking the validity of the speed and/or acceleration information; C) in case the speed and/or acceleration information is determined as being valid: operating the elevator system (2) based on the calculated positional information; D) in case the speed and/or acceleration information is determined as not being valid: D1) starting a timer; D2) controlling the at least one elevator car (12) to run by the at least one positional sensor (24, 26, 63, 83, 93) for re-calibrating the positional information of the at least one elevator car (12); and D3) stopping any operation of the elevator system (2), in case the at least one elevator car (12) has not run by the at least one positional sensor (24, 26, 63, 83, 93) within a predetermined period of time from starting the timer.

    摘要： A ground fault detection apparatus (32) for detecting a ground fault of a safety chain (10b; 10c; 10d), in particular a safety chain (10b; 10c; 10d) of a people conveyor, comprises: a supply line current monitoring unit (26), which is configured for measuring a current flowing into the safety chain (10b; 10c; 10d) and providing a first signal indicative of the amount of current flowing into the safety chain (10b; 10c; 10d); a return line current monitoring unit (28), which is configured for measuring a current flowing out of the safety chain (10b; 10c; 10d) and providing a second signal indicative of the amount of current flowing out of the safety chain (10b; 10c; 10d); and a comparison unit (30), which is configured for comparing the first and second signals and issuing an alarm signal in case the difference between the first and second signals exceeds a predetermined limit.
