PROBLEM TO BE SOLVED: To precisely detect that abnormal excitation is applied to a passenger cage by jumping of a passenger, etc., in the cage. SOLUTION: A difference of previously set passenger cage standard speed and passenger cage actual travelling speed is compared with a previously set standard value L and its comparison result is derived at a first comparison judgement part 92, and its result is displayed on a display 14 provided in a cage 1. Consequently, a passenger in the cage 1 can recognize that a value of the difference exceeds the previously set standard value L and that speed control of the passenger cage becomes abnormal by the display 14. In a state where the passenger in the cage intentionally operates to excite, it is discriminated from abnormality of speed control by failure of the other control system and an elevator can be speedily started by immediate stoppage of excitation act in the cage, and accordingly, it is possible to improve operation efficiency. |
