Abstract
Description
- The present invention relates generally to an indicator system and method for an elevator.
- In conventional elevator systems commonly installed in office buildings, apartments, etc., each floor of the building is provided with a hall button for calling the elevator car to a floor on which the hall button has been pressed. When the elevator car arrives at the designated floor, the elevator car stops and the doors thereof open for taking on passengers.
- However, in a building there are various floors at which boarded passengers may wish to disembark the elevator car while other passengers may wish to board at the same floor. Thus it may occur that boarding passengers may attempt to get into the elevator car before disembarking passengers have gotten out. This presents inconvenience and possible injury to elevator users and impedes smooth flow of elevator service.
- It is a principal object of the present invention to overcome the drawbacks of the prior art.
- In order to accomplish the aforementioned and other objects, a disembarkation indication method for an elevator is provided, comprising the steps of: calling an elevator car to a particular floor by pressing a hall button on the floor; comparing the floor number of the floor with floor numbers of floors selected as destination floors, the destination floors being selected by passengers within the elevator car by depressing a destination floor button within the elevator car; turning ON a disembarkation indicator on the floor when the floor number of the floor coincides with a selected destination floor; monitoring the floor for determining whether or not the elevator car has arrived at the floor; and turning OFF the disembarkation indicator when the elevator car arrives at the floor on which the hall button has been pressed and which has also been selected as a destination floor.
- According to another aspect of the invention, a disembarkation indicator system for an elevator is provided, comprising: a hall button provided on a floor serviced by an elevator car, the hall button outputting a call signal indicative of the floor upon depression thereof; a destination floor button provided inside the elevator car, depression of the destination floor button outputting a destination signal indicative of a selected floor upon depression thereof; a sensor provided on a floor on which the hall button is provided for outputting an arrival signal indicative of elevator arrival at the floor (preferably a door zone sensor outputting a signal indicative of elevator door opening); a disembarkation indicator provided on the floor and responsive to ON and OFF signals to be turned on or off; and a control unit receivable of the call, destination and arrival signals and operable to stop the elevator car at the floor if the call signal has been received and at a floor selected by depression of the destination button, and further operable so as to output an ON signal to the disembarkation indicator when the destination signal corresponds to the floor if the call signal has been received and to output an OFF signal to the disembarkation indicator upon receiving the arrival signal.
- According to still another aspect of the invention, a disembarkation indicator system for an elevator is provided, comprising: a plurality of hall buttons, one hall button respectively provided on each floor serviced by an elevator car, each of the hall buttons outputting a call signal indicative of the respective floor on which the hall button is located, upon depression thereof; a plurality of destination floor buttons provided inside the elevator car, each of the destination buttons respectively indicative of one of the floors serviced by the elevator car, depression of one of the destination buttons causing a destination signal, indicative of a floor corresponding to the destination button, to be output upon depression thereof; a plurality of sensors provided on the floors serviced by the elevator car, each of the sensors outputting an arrival signal indicative of its corresponding floor upon elevator arrival at the floor (preferably door zone sensors outputting signals indicative of elevator door opening); a plurality of disembarkation indicators provided on said floors serviced by the elevator car and respectively responsive to ON and OFF signals to be turned on or off; and a control unit receivable of the call, destination and arrival signals and operable to stop the elevator car at each floor from which a call signal has been received and at each floor selected by depression of one of the destination buttons, and further operable, when a floor for which a destination signal has been received corresponds to a floor from which a call signal has been received, to output an ON signal to the disembarkation indicator provided on the floor and, when an arrival signal is received from the floor, to output an OFF signal to the disembarkation indicator provided on the floor.
- Thus, the present invention provides an elevator system in which passengers waiting to board an elevator car are informed if there are other passengers waiting to disembark at the same floor.
- The present invention provides a disembarkation indicator system and method, for signaling waiting passengers that other passengers will disembark at the floor on which they are waiting, and so promotes smooth boarding and disembarkation of the elevator car.
- An embodiment of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:-
- Fig. 1 is a block diagram showing the components of a disembarkation indicator system for an elevator according to an embodiment of the present invention;
- Fig. 2 is a front view of a hall button panel and a door for boarding and/or disembarking an elevator car; and
- Fig. 3 is a flowchart of a program executed for controlling the disembarkation indicator system according to the method of the present invention.
- Referring to Fig. 2, it may be seen that the elevator disembarkation indicator system according to the present embodiment comprises a
door 1, provided respectively at each floor serviced by the elevator for boarding and disembarking an elevator car (not shown). To the left of thedoor 1 in the drawing anarrival indicator panel 2 is provided. Thearrival indicator panel 2 includesnumerical indicators 3 for each floor to indicate the present position of the elevator car (not shown). The numerical indicators may be backlit by a pilot light for example in a per se known fashion. Like thedoor 1, thearrival indicator panel 2 may be provided on each floor serviced by the elevator. - Below the arrival indicator panel a
hall button 4 is provided. Thehall button 4 comprises anUP button 4a and aDOWN button 4b for allowing a passenger wishing to board the elevator car to indicate whether his/her destination floor is higher or lower than the present floor and to stop the elevator car when it is traveling in the appropriate direction. Referring to Fig. 1, when theUP button 4a or thedown button 4b of thehall button 4 is pushed, a CALL signal representative of a floor on which the hall button is located is output to thecontrol unit 5 of the elevator disembarkation indicator system. Like thedoor 1 and thearrival indicator panel 2, thehall button 4 may be provided on each floor serviced by the elevator. - Within the elevator car (not shown) a plurality of
destination floor buttons 6 are provided. When one of thefloor buttons 6 is depressed, a DEST (destination) signal indicative of the selected floor is output to thecontrol unit 5 and thecontrol unit 5 is then active to operate the elevator car to go to the selected destination floor. - Referring again to Fig. 2, according to the present embodiment, a 'PASSENGERS DISEMBARKING' indicator light 7 (hereinbelow: disembarkation indicator 7) is provided between the
arrival indicator panel 2 and thehall button 4. Thedisembarkation indicator 7 may be comprised of a transparent, or translucent,panel 7a backed by a pilot light, which may be a light emitting diode (LED) such as a semiconductor chip or the like mounted in a metallic lead frame encased in synthetic resin, for example. - When a DEST signal is received at the
control unit 5 which corresponds to a floor for which a CALL signal has been received, the control unit is active to switch thedisembarkation indicator 7 ON at the appropriate floor. - Further, the system of the invention includes a
door zone sensor 8 provided at each floor serviced by the elevator for determining when the elevator car has reached a selected destination floor. That is to say, when the elevator car stops at a floor which has been designated by a passenger pushing one of thedestination floor buttons 6, the door zone sensor is active to output an ARRV (arrival) signal to thecontrol unit 5 when the elevator car stops at that floor. When the ARRV signal received by thecontrol unit 5 corresponds to a floor for which a CALL and DEST have been received, that is, when the ARRV signal is received from the floor on which the disembarkation indicator has been turned ON, thecontrol unit 5 is active to switch thedisembarkation indicator 7 OFF. - It will be noted that the above arrangement may be suitably utilized in elevator systems having more than one elevator car. According to this, whereas, at each floor, a
single call button 4 is applicable to call one of a plurality of elevator cars,separate disembarkation indicators 7 are respectively provided for each of the elevator cars in the system, at cach floor. Accordingly, a plurality ofdoors 1 and a plurality ofdoor zone sensors 8 must also be provided at each floor. In other respects, the system is operable identically to the above described arrangement. - Hereinbelow, a simplified explanation of a program executed by the
control unit 5 for operating the elevator disembarkation indicator system according to the method of the invention will be described with reference to the flowchart of Fig. 3. - First, at a step S1, when a passenger presses the
hall button 4, the CALL signal is output to thecontrol unit 5. - Then, at a step S2, it is determined if a
destination button 6 in the elevator car has been pushed for the same floor from which the CALL signal was received in step S1. - If the answer is NO at step S2 the routine goes to end, however, if the answer is YES at step S2, the routine proceeds to step S3.
- At step S3, the
disembarkation indicator 7 of the floor on which the hall button was pressed is turned ON by thecontrol unit 5. - At a step S4 it is determined whether the elevator car has arrived at the designated floor for which the
hall button 4 and thedestination button 6 in the elevator car (not shown) have been pressed. That is, thecontrol unit 5 receives the ARRV signal from thedoor zone sensor 8 at the designated floor. If the answer is NO at step S4, this step is repeated until a YES determination is made and the routine proceeds to a step S5. - At step S5, after arrival of the elevator car at the designated floor, the
disembarkation indicator 7 is turned OFF by thecontrol unit 5 and the routine proceeds to END. - It will be noted that the present invention is not exclusively limited to the embodiments recited above and various modifications may be effected within the scope of the invention. For example, the present invention may be suitably implemented with or without the
arrival indicator panel 2. Further, though the above embodiment teaches a single elevator car, the system and method of the invention may be utilized for elevator systems in which a plurality of elevator cars are provided. Also, the system and method of the invention are effective even when a plurality of destination floors have been designated by waiting passengers pressing hall buttons on more than one floor and a plurality of destination floors have been selected for disembarkation by passengers on the elevator car. - Thus, according to the present invention, passengers waiting to board an elevator car are informed in advance that other passengers arc waiting to disembark at the same floor. According to this arrangement, smooth boarding and disembarking of the elevator car may be effected and smoother flow of elevator traffic resulting in an improved level of elevator service may be reliably obtained. Further, such improvements may be implemented with relatively simple components at low cost to the operator and/or elevator manufacturer.
- While the present invention has been disclosed in terms of the preferred embodiment in order to facilitate better understanding thereof, it should be appreciated that the invention can be embodied in various ways without departing from the principle of the invention. Therefore, the invention should be understood to include all possible embodiments and modification to the shown embodiments which can be embodied without departing from the principle of the invention as set forth in the appended claims.
