摘要:
An elevator car group control system for controlling a plurality of elevator cars arranged for parallel operation for serving a plurality of service floor landings of a building, comprising means for selecting suitable ones of the cars for serving hall calls, and means for forecasting the length of time required for each of the selected cars to arrive at each of the allotted hall call originating floors and displaying the forecast waiting time on display means disposed at the landing of each of the floors. In the invention, the serving car selecting means comprises means for detecting for each car the number of floors subject to change in forecast waiting time displayed at each of the already allotted floors when a new hall is originated from one of the floors, and means for preferentially selecting the car detected to provide a smaller number of floors subject to such change than the others. That is, in response to the origination of a new hall call, the number of floors subject to change in already displayed forecast waiting time due to the allotment of the new hall call is detected for each of the cars, and the car providing a smaller number of floors subject to such change than the others is preferentially selected to respond to the new hall call.

An elevator control system for controlling a plurality of elevator cars arranged for parallel operation for servicing a plurality of floors of a building, in which means are provided so that, in response to origination of a new hall call in addition to hall calls originated and allotted already, a suitable elevator car for servicing this new hall call can be selected and the new hall can be allotted to the selected elevator car to be serviced by this elevator car. In the system, this new hall call is allotted preferentially to one of the elevator cars having an already instructed stopping floor within a predetermined floor range covering a plurality of backward and/or forward floors contiguous to the new hall call originating floor. In this elevator control system, the already instructed stopping floor is evaluated by employing a weight coefficient which is variable depending on the factor such as the position of the already instructed stopping floor either backward or forward relative to the new hall call originating floor, or the relative distance between such floor and the new hall call originating floor, so as to provide improved elevator service.
摘要:
Elevator group supervisory control method and system for group supervisory control of a plurality of elevators serving a plurality of floors. The method and apparatus of the invention permits the inputting of qualitative requests (guidance), from the user, concerning elevator operation into the group supervisory control system. Qualitative requests concerning elevator operation are set in the form of guidance (or request) targets. The thus set request, targets are converted into control targets for the elevators. Actual group supervisory control is executed using the control targets.

An apparatus for recognizing and displaying handwritten characters and figures in which input stroke information on a handwritten input character or figure is read out by an electromagnetic tablet, recognition means performs character/figure recognition on the basis of the feature of the input stroke information, display means displays the input stroke information and the result of recognition, and when the result of recognition is displayed on a display screen of the display means, stroke information having been used for recognition is erased from the display screen, and stroke information which is not yet used for recognition, is left on the display screen.
摘要:
An elevator control apparatus in which a three-phase AC output from a three-phase AC generator rotating with running movement of an elevator car is converted into a train of pulses, and the number of such pulses is counted by a counter which provides a count indicative of the position of the elevator car. When the elevator car is actuated to start from its standstill condition, the running direction of the elevator car is detected on the basis of the direction of phase rotation of the three-phase AC output from the generator, and a predetermined correction data is added to or subtracted from the count depending on the detected running direction of the elevator car so as to correct the count error appearing in the starting stage of the elevator car.

摘要:
A hand-written character/graphic is recognized in a character recognition mode or a graphic recognition mode designated in accordance with stroke information supplied from a tablet input device which samples the hand-written character/graphic and converts it to the stroke information. The recognition mode is automatically designated by comparing a longer one of projection lengths on x-axis and y-axis of stroke coordinates with a predetermined threshold for a hand-written character input.
摘要:
Coordinates of a handwritten pattern drawn on a tablet are sequentially sampled by a pattern recognition unit to prepare pattern coordinate data. Based on an area encircled by segments created by the sampled pattern coordinate data of one stroke and a line connecting a start point and an end point of the one-stroke coordinate data, the sampled pattern coordinate data of the one stroke is converted to a straight line and/or curved line segments. The converted segments are quantized and normalized. The segments of the normalized input pattern are rearranged so that the input pattern is drawn in a predetermined sequence. Differences between direction angles for the rearranged segments are calculated. Those differences are compared with differences of the direction angles of the dictionary patterns read from a memory to calculate a difference therebetween. The matching of the input pattern and the dictionary pattern is determined in accordance with the difference. If the matching fails, the first or last inputted segment of the input pattern is deleted or the sampled pattern coordinate data of the next stroke is added, to continue the recognition process.
摘要:
An elevator group control system in which, in response to origination of a new hall call, a floor-stop call evaluation factor indicative of the degree of saving of power consumption is computed besides a serviceability evaluation factor indicative of the passenger serviceability, for example, the waiting time. One of these evaluation factors is weighted relative to the other to compute an allocation evaluation factor indicative of the suitability of allocation of the new hall call to one of the elevator cars, and the new hall call is allotted to the elevator car which is decided to be most suitable for the service in respect of the value of the allocation evaluation factor.
摘要:
In an elevator system in which an elevator car serves a plurality of floors in response to hall calls and cage calls, the number of, for example, up hall calls originated from, for example, the 2nd floor is counted, and the number of cage calls, classified by destination floors, registered in the elevator car after the elevator car has served each of the up hall calls is also counted. The count of the hall calls and the count of the cage calls classified by destination floors are compared with each other, and, on the basis of the result of comparison, the probabilities of origination of cage calls, classified by destination floors, which will be registered in the elevator car after the elevator car has subsequently served a new up hall call which would be originated from the 2nd floor, are calculated for forecasting future cage calls.
