Abstract (en)

[origin: EP1544151A1] An elevator door control device is provided in which the precision of abnormality detection in door opening and closing operations is increased by appropriately detecting abnormalities in torque commands, so that there is little erroneous detection of abnormalities in door opening and closing operations. The elevator door control device has: a speed command portion that outputs a speed command; a speed control portion that outputs a torque command corresponding to a deviation between the speed command and a feedback speed; a reference torque command pattern storage portion that stores a plurality of torque command patterns that are formed by a plurality of the torque commands sampled according to door opening and closing operations, and stores a reference torque command pattern that is obtained based on the torque commands at each common sampling of the plurality of torque commands; an abnormality detection torque pattern generator portion that generates an abnormality detection torque pattern from the reference torque command pattern; and an abnormality avoiding unit that outputs an abnormality avoiding command to the speed command portion when the torque command exceeds the abnormality detection torque pattern. <IMAGE>
