The invention concerns a method for solving an optimization task consisting of a plurality of sub-functions in the control of the operation of an apparatus. In the method, a set of a plurality of solution alternatives is generated and, according to the method, each sub-function is normalized. Normalized cost functions of the sub-functions are generated for each solution alternative for solving the optimization task, and based on the normalized cost functions of the sub-functions, a set of solutions to the optimization task is formed. From the set of solutions, the best solution is selected and the apparatus is controlled in accordance with the solution thus selected.

Provided is an elevator group control apparatus which brings distributed standby control into action when the movement of users is heavy in one direction in an unbalanced manner in time zones which account for large proportions of an elevator use condition of a day, for example, in off-hour zones and time zones in which traffic demand is relatively small, thereby improving the waiting time of users, and does not bring distributed standby control into action when there is no unbalanced condition of the movement of the users, whereby it is possible to perform energy savings by reducing power consumption during runs without greatly worsening the waiting time of the users. In an elevator group control apparatus which performs the operation control of a plurality of elevators, there is detected a downward traffic flow ratio of traffic flows departing downward from floors higher than a prescribed main floor in the total traffic flow departing from one floor to another. If the downward traffic flow ratio is not less than a prescribed reference value, a standby mode for downward traffic flow is made effective. If the above-described standby mode for downward traffic flow has been made effective, at least one elevator car is caused to be on standby on a floor higher than the main floor and at least one elevator car is caused to be on standby on the main floor.

The invention relates to elevator systems, in which a number of elevators operate in the same hoistway. The elevator system comprises at least one shuttle elevator and at least two local elevators, the elevator cars of which are arranged to travel in the same elevator hoistway such that they can serve at least one shared transfer floor of a transfer level. The control system of the elevator system receives destination calls given from a destination call appliance, forms a plurality of route alternatives and allocates a destination call to one or more elevators by selecting the best route alternative. When allocating a destination call, the control system takes into account that the elevator cars of the local elevators that travel in the same elevator hoistway cannot simultaneously be at a shared transfer floor in cases in which the route alternative comprises a part-trip with a local elevator and a change of elevator at a shared transfer floor.

The object of the invention is an elevator system and a method for controlling an elevator group. The elevator system according to the invention comprises an elevator group, which comprises at least two elevator cars (1, 1'), which elevator cars are fitted to be moved in the elevator hoistway (2, 2') according to the calls allocated by the control (3) of the elevator group. The elevator system comprises a power supply arrangement (5, 5'), for adjusting the power needed to move the elevator cars (1, 1'). An energy storage (6, 6') is connected to the power supply arrangement. The energy storage is fitted in the first operating situation to yield energy for use in moving the elevator car, and in the second operating situation to receive energy released by movement of the elevator car. The elevator system comprises a determination of the charging status of the energy storage, and the control (3) of the elevator group is fitted to determine the change in energy that would be caused by the movement according to an allocated call of the elevator cars (1, 1') belonging to the elevator group. The control (3) of the elevator group is fitted to allocate a call by favoring in the allocation an elevator car (1, 1' ), the determined change in energy caused by the movement of which best meets the allocation criterion.

The present invention discloses a method and a system for modernizing at least one elevator group (1000), which comprises a plurality of elevators (A, B, C, D), a group control (1100) that controls the elevator group as well as call-giving appliances connected to the group control via the landing appliance bus (1112). According to the solution a new group control, new call-giving appliances (1301 ) for the floor levels and also a new landing call bus (1302) are installed in the elevator group; a new group control (1300) is connected to the pushbutton interface (M1,...,M10) of the old call-giving appliances for transmitting calls given by passengers from the new group control (1300) to the old group control (1 100). The elevator calls given by passengers are divided between the modernized subgroup (1300,A,B) and at least one unmodernized subgroup (1 100, C, D) on the basis of the given selection criterion, and a call addressed to the modernized subgroup is allocated in the new group control to the modernized elevators or a call addressed to the unmodernized subgroup is transmitted via the pushbutton interface (M1,...,M10) to the unmodernized subgroup.

Ein Verfahren zur Steuerung einer Aufzugsanlage mit mehreren Aufzügen, bei dem Zielrufeingaben (NZR) von Passagieren über Zielrufeingabegeräte eingegeben werden und bei dem wenigstens ein eine Verkehrsintensität (MVI) kennzeichnendes Verkehrskriterium der Aufzuganlage von einer Aufzugssteuerung (16) gemessen wird, wobei die Aufzugssteuerung (16) den Zielrufeingaben (NZR) kostenoptimierend Aufzüge zuteilt. Um eine Energieeinsparung bei Aufzugsanlagen mit Zielrufsteuerung zu erhalten, ohne die Transportkapazität der Aufzugsanlage zu beeinträchtigen, wird vorgeschlagen, dass die Aufzugssteuerung (16) den Zielrufeingaben (NZR) zusätzlich energieoptimierend Aufzüge in Abhängigkeit von dem Verkehrskriterium (MVI) zuteilt.
摘要:
A system for controlling the elevators in an elevator system based on passenger presence. The elevator system includes a number of elevators (1A . . . 1H) wherein first sensor members (2, 2A . . . 2H), second sensor members and additional sensor members are arranged in a waiting area of each elevator (1A . . . 1H) on each floor (F, F1, F2, F3 . . . Fn). The first, second and additional sensor members are fitted to give information about the presence and number of passengers waiting to go either up or down for an elevator at least in the waiting area in question. A controller is provided for controlling the elevators. The controller receives information from the first, second and additional sensor members 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 first, second and additional sensor members.
