<P>PROBLEM TO BE SOLVED: To provide a control device for an elevator capable of improving the comfortableness at the start of running and of saving labor to perform the inspection and adjustment of an intra-car load sensing means and the inspecting operation for a resilient member located between the car undersurface and the car frame. <P>SOLUTION: The elevator is structured so that the resilient member 4 for isolating vibrations is installed between the car frame 1 and the undersurface 3 of the car 2 and a load sensor 5 for sensing the load in the car 2 is mounted on the frame 1, and is controlled by an elevator control part 7 and an elevator diagnosing device 19. The elevator diagnosing device 19 is equipped with a predicting means 12 consisting of a load data storing part 16 to store in time series the output values of the load sensor 5 when inside the car 2 is in the no-load condition and a load data arithmetic processing part 17 to compute the correction value when the output value of the load sensor 5 is put in the zero-point set correction in case inside the car 2 is in the no-load condition and predicts the timing at which the deflection amount of the resilient member 4 and/or the floor surface of the car 2 will exceed the effective sensing range of the load sensor 5. <P>COPYRIGHT: (C)2004,JPO |
