摘要:An elevator system for controlling cars on the basis of their paration from a destination, particularly for assigning hall calls to individual cars on this basis. The prence of an abnormally long spacing between a car and a destination, such as a hall call to be assigned, is nd and a signal generated to reprent that spacing. Landing count can be employed for normal spacing and a characteristic signal is utilized for the long spacing as encountered with a blind hatch region. A fixed pul count is developed for each of the relatively uniform spaced landings and a proportionally longer pul count is employed for the long travel increment of a blind hatch traver. The blind hatch rvice factor is reprented by a predetermined number of puls which are accumulated on a per car basis in a master counter with other pul ries reprenting various rvice factors. The total counts for the cars are then compared and the hall call is assigned to the car with the lowest count as being best suited to rve the call.
