FI118216B - Elevator system e.g. freight elevator for use in building, has control system arranged to allocate freight elevator as response to call received from call pushbutton of freight elevator - Google Patents

Abstract

The system has call pushbuttons (5, 7) for reserving passenger elevators (2) and a freight elevator (3) for use by passengers. A control system (9) is arranged to allocate the freight elevator as a response to a call received from the call pushbutton (7) of the freight elevator. The system allocates passenger elevators or the freight elevator to a user as a response to the call received from the call pushbutton (5) of the passenger elevators. The call is transmitted to the control system, which allocates the passenger elevators or freight elevator to the user. An independent claim is also included for a method for controlling an elevator system.

FIELD OF THE INVENTION

The present invention relates to elevator systems.

In particular, the present invention relates to an elevator system in which passenger and freight elevators have a common control system but separate call buttons. The invention further relates to 10 methods for controlling an elevator system.

BACKGROUND OF THE INVENTION

In the elevator system, the operation of the elevators is controlled by user V

based on invitations. The elevator control system 15 receives an external call from the up / down buttons in the lobby and attempts to determine which of the elevator group's elevators is best able to serve the caller.

Specifying a user-friendly elevator is called call allocation. Frequently, the elevator closest to the user 20 is selected for the call, but other ΓΓ: attributes can also be used as allocation criteria.

Often in buildings, for example, a freight elevator is needed to serve in addition to the standard passenger lift system. users, in particular for the movement and transport of goods on different layers. The cargo elevator may be separate from the passenger-10 stand and may be provided with separate call buttons for each floor level, whereby the cargo elevator also has its own control system. If the user needs a freight elevator, he can go to the freight elevator and press the call button. As the freight elevator is generally less frequently needed than passenger elevators, the goods elevator can also be used for passenger transport when users do not need freight. Sometimes the freight elevator and the standard passenger elevator or elevators are adjacent. In this case, the elevator system may be misused by purposefully depressing both the cargo elevator button and the passenger elevator button. As a result, two elevators are directed to the call layer even though the actual need is only one elevator.

When the freight elevator is part of the passenger elevator system according to Fig. 1, the user can only give the call by pressing the j button 5 in the desired direction of travel, and one of the elevator cars 1 of the elevator system 1 is allocated to the user.

5 The problem with such a combined system is that the user cannot select the goods elevator, but the goods elevator is only allocated to the user if it is suitable according to the allocation criteria. If the freight elevator and passenger elevators have separate control systems and thus also separate call buttons 10, this often causes users to press the buttons of both elevators simultaneously (for only one journey), whereby one of the elevators is unnecessarily directed to the starting floor.

15 PURPOSE OF THE INVENTION

The object of the present invention is to eliminate or alleviate the above-mentioned prior art problems and to provide a solution which is simple and easy to implement. It is an object of the present invention to provide a method for controlling an elevator system and an elevator system in which the user has the choice to operate a freight elevator but which still allows the allocation of a cargo elevator for passenger transport.

With respect to the features of the present invention, reference is made to the claims.

Thus, some of the attributes contained in the claims below may be redundant for individual inventive ideas. Aspects of various embodiments of the invention may be applied within the scope of the inventive concept with other embodiments.

An object of the invention is to provide an elevator system in which the freight elevator is part of a passenger elevator system. In other words, the control system for the 15 elevator groups controls both the special elevators and the v elevator groups, but which elevator system?

An advantage of the proposed solution is that a common control system can be arranged for the whole elevator group, which controls both passenger elevators and special elevators, for example 10 freight elevators. If no freight elevator is needed, the control system also allocates the freight elevator for passenger transport. The use of a freight elevator for passenger transport increases capacity and thus reduces congestion. When 15 separate up / down buttons are provided for the freight elevator, the user can also reserve the freight elevator for his own use if necessary. Because the control system handles only one call at a time: ¾ f · ® given from the same layer, pressing both buttons is of no use, and neither button; 20 misuse of printing or control of two elevators on the same floor will thus occur. With the invention, the service level of the elevator system can be further improved and: |: * i made the system more user-friendly.

DETAILED DESCRIPTION OF THE INVENTION

Fig. 2 shows an elevator system 8 according to the invention, which system comprises one or more passenger elevators 2 and at least one special elevator 53 (for example, freight elevator), for passenger elevators and! a lift control system 9 common to the freight elevator and a s light or signboard 6 which can indicate on which floor the elevator is or in which direction the elevator arriving on the floor is traveling. The system further comprises call buttons 10 for reserving the elevator for use by the passenger and call buttons 7 in particular for reserving the goods elevator for use by the passenger.

The user of the elevator system according to the invention presses the call button 5 of the 15 passenger elevators unless he / she specifically needs a cargo elevator. The call is forwarded to the elevator control system 9, which allocates a suitable elevator (either passenger elevator 2 or freight elevator 3) to the user. If the user needs a cargo elevator, he presses the call button 7 of the cargo elevator 20, whereby the control system 9 allocates the cargo elevator to the user according to the allocation criteria.

«· · * · * * The user can then call either the '5' buttons on the passenger lifts or the 7 buttons on the freight elevator.

> # * j * 25 The elevator control system 9 allocates a suitable elevator to the user, depending on which elevator call button is located? ; j * j printed. If the user only needs a freight elevator and ···. ** ·. only presses the call button for the freight elevator, the elevator system · · f allocates the freight elevator to the user and prevents invitations to other than 30 freight elevators to that floor. If the user does not need a freight elevator, he / she may be allocated * · * ··· * any suitable elevator (including * '· u: freight elevator). I call the freight elevator · ** * ♦ ***; • · * * can be assigned to an invitation given by the call button. 35 Allocation criteria in which the freight elevator »·· * ··· # is allocated, for example, as soon as the goods elevator is free ***** * * or only in the order when the goods elevator is freely allocated ...: 118216: 7. The call buttons may be cross-linked so that the control system does not accept another call until the "first called" elevator has arrived. That is, if the freight elevator call button has been pressed, the call from the passenger elevator call button will not be accepted until the freight elevator has arrived and -1 has left (or after a certain delay). Similarly, if the elevator call button is pressed, the freight elevator invitation will not be accepted until the passenger elevator has arrived at 10 locations (or will only be accepted after a certain delay).

Although the elevator system of the above examples has a plurality of passenger lifts, the invention can also be applied to a simple system having only one passenger elevator and another freight elevator larger than a passenger elevator. The goods lift need not necessarily be a lift specifically intended for the carriage of goods, but it may also be another type of lift such as a sight lift or an elevator whose doors are wider than those of a passenger lift. Also, in the allocation of 20 lifts, it is possible to determine a variety of allocation criteria for the order and manner in which the freight elevator is allocated.
