专利汇可以提供Elevator control for optimizing allotment of individual hall calls to individual cars专利检索，专利查询，专利分析的服务。并且A system for assigning individual hall calls to individual elevator cars on the basis of service requirements imposed on the cars wherein signals associated with calls are time multiplexed and service requirements are represented by predetermined numbers of signal pulses which can be correlated to the anticipated delay imposed on the car in reaching the landing of the call and/or in travel commitments beyond the landing of the call. Pulse series for the several service requirements such as distance of the car from the call landing, car calls and hall calls assigned the car between the car and the call landing, and car calls and hall calls assigned the car beyond the call landing, are sequenced on a per floor basis as by a car travel scanning means so that one floor is considered at a time as to calls and then as to car travel distance so that no overlap of pulses is generated. Pulse series for car status representing conditions imposed upon the car as degree of loading, car in slowdown, door open, and car in acceleration are also sequenced to avoid overlap of pulses for the several factors. Pulse counts are accumulated for each of a plurality of cars to indicate the car best suited to serve the call to be assigned as that having the pulse count representing the least service commitment.，下面是Elevator control for optimizing allotment of individual hall calls to individual cars专利的具体信息内容。
