Abstract:
The invention relates to a method for handling destination calls in an elevator group comprising several elevators using destination call control, which method comprises an allocation procedure for situations where the calls can't be served by all elevators of the elevator group in one round trip, in which situation "n" open calls and "m" fixed calls are present, which fixed calls are already allocated but not served, in which allocation procedure a genetic algorithm (GA) is used in which the following succession of steps is performed: a) chromosomes comprising genes are formed, in which chromosomes: - n first genes comprise a correlation of each open call and a corresponding elevator, - n second genes comprise a correlation of each open call and the corresponding number of the round trip in which the open call will be served, and - m third genes comprise a correlation of each fixed call and the corresponding number of the round trip in which the fixed call will be served, b) for each chromosome round trips are calculated for each elevator of the elevator group according to collective control, c) the round trips of all elevators calculated in step b) are evaluated according to known optimization criteria, as e.g. passenger riding time, passenger waiting time, energy consumption, minimum number of round trips etc., d) chromosomes which are evaluated in step c) as sufficient are put forward to the forming of a new generation by per se known GA methods, as e.g. cross-breeding, mutation, etc., e) the steps b) to d) are repeated for each chromosome of each new generation of chromosomes until a stop criterion is achieved, f) the calls are served in collective control according to the best chromosome of the last generation, and g) the destinations of each elevator in its travelling direction in the current round trip according to the best chromosome are shown on a at least one common display shortly before its arrival at said landing. The invention solves the elevator dispatching problem under consideration of more than the current round trip of the elevators in the elevator group.
Abstract:
System for controlling the elevators in an elevator system, which elevator system comprises a number of elevators (1A...1 H). The system comprises first sensor means (2, 2A...2H), which are arranged in the waiting area of each elevator (1A...1 H) on each floor (F, F1, F2, F3... Fn), which sensor means (2, 2A...2H) are fitted to give information about the presence and number of passengers waiting for an elevator at least in the waiting area in question; means for controlling the elevators, which means are fitted to receive information from the sensor means (2, 2A...2H) about the presence and number of passengers waiting for an elevator and to control the movement of the elevators of the elevator system utilizing the information received from the sensor means.
Abstract:
The present invention discloses a method and a system for the allocation of elevators on the basis of calls in an elevator system. The method produces for different route alternatives a cost function wherein the traveling time of each passenger is calculated. The calculation of the traveling time is performed taking into account the time spent while waiting for an elevator at a floor, the ride time in the elevator car, the delaying effect of active landing and car calls on the traveling time and the delaying effect of car calls given by new passengers entering at intermediate stops. The method is advantageous in the destination call system, but in the traditional up-down call system it is possible to utilize information provided by traffic statistics to predict the destination floor. Route alternatives can be created e.g. by using genetic algorithms. Once the route alternative giving the shortest average traveling time has been calculated, the elevators are controlled according to this route. In intensive traffic conditions, traveling time is optimized, and in quiet traffic conditions, passenger waiting time is optimized.
