Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an elevator calling device, and more particularly to a technique for displaying hall calls and their assignments for group control elevators.

(Prior Art) In recent years, in order to efficiently operate elevators installed in parallel, a group management control method that comprehensively controls all elevators has become mainstream. This comprehensive control is to promptly select a service elevator for elevator users at a landing and have it operate to that landing.When an elevator user registers a call button for a landing, the service elevator is instantly activated. It is also called the instant lighting system because it notifies people and encourages them to move closer to the elevator.The advent of this system has improved inter-floor traffic in buildings with multiple floors, and it has become established as an elevator control method in high-rise buildings. It is being done. The purpose of such a group management control system is to facilitate elevator operation by allowing elevator users to board the elevator efficiently, or to improve response to elevator users.

(Problem to be solved by the invention) However, in the current instant lighting system, service elevator notifications are transmitted as the same information to all elevator users at the landing, so for example, when an elevator with a capacity of 20 people is When servicing a floor with 30 elevator users at a landing, 20 people can get on the elevator, but the remaining 10 people cannot get on the elevator and have to take the next elevator. All I can do is wait. In this case, if the reserved elevator was put into service first in terms of group 1 management control, it could be said that the reservation was rejected, but from the viewpoint of the elevator users at the landing, 10 out of 30 people were betrayed by the original reservation, and the elevator at the landing Overall, it cannot be said that the service has been completed, but it can be said that the reservations for the remaining 10 people have been lost.In other words, in the conventional group management control system, the target of notification is the elevator users of 1 Å or more, so the above It is not possible to improve such inconvenient phenomena.

Therefore, it has been desired to develop a so-called individual-based notification means that targets a single elevator user.

In view of the above-mentioned problems, the present invention improves services for users of group control elevators more than ever by making the target of notification of service reservations for hall calls in group control elevator systems to individual elevator users. The point is to make it happen.

[Structure of the invention]

(Means for Solving Problems) In the elevator calling device of the present invention, a portable card carried by each elevator passenger includes a switch for specifying a destination floor and a destination floor specified by this switch. A transmitting circuit that converts and transmits the code; a receiving circuit that responds to this destination floor code and receives the code of the elevator for which the service is to be reserved; and a display that receives the reserved elevator code and displays the number of the elevator for which the service is to be reserved. Further, the sensor panel installed near the landing of the elevator hall includes a receiving circuit that receives the destination floor code transmitted by the transmitting circuit of the portable card and sends it to the group management control section, and a sensor panel that receives the destination floor code transmitted by the transmission circuit of the portable card and sends it to the group management control section. and a transmitting circuit for receiving a reserved elevator code selected by the elevator in response to the destination floor code and transmitting it to the receiving circuit of the portable card.

When an elevator passenger carrying the above-mentioned portable card specifies the destination floor using a switch provided on the portable card near the landing area of the elevator hall, this is converted into a destination floor code and a sensor panel installed near the landing area converts this into a destination floor code. is transmitted by the transmitting circuit toward.

The receiving circuit of the sensor panel receives this destination floor code and transmits it to the group management control section, and the group management control section responds to this destination floor code and sends out the most suitable elevator as a service elevator, and depending on the result, At the same time, this service elevator is set as a reserved elevator and the code of the elevator is transmitted from the transmitting circuit of the sensor panel to the receiving circuit of the portable card, and the receiving circuit of the portable card receives this reserved elevator code. The number of the elevator for which the service has been reserved is displayed as an image on the display to inform the elevator user of the elevator that is to be serviced.

This is a system configuration diagram of an embodiment of the sensor panels installed near the landing of each floor in the group control elevator system. 4
When received by the receiving antenna 8, the demodulation circuit 4b converts it into a digital signal and sends it as a destination floor signal to the elevator control unit 13, and conversely, the modulation circuit 3b converts the digital signal from the elevator control unit 13 into a display signal. After input, the data is converted and transmitted from the transmitting antenna 3a as a message shown in FIG.

FIG. 3 is an embodiment of the elevator control section of the present invention.
Reference numeral 15 in the figure is a multiple input circuit, which inputs the destination floor signal from the sensor panel of each floor.The floor identification control unit 17 in the figure inputs the destination floor signal from the sensor panel of each floor. and its direction, and generates a service floor data signal. For example, if the destination floor is the 9th floor and the signal transmission floor is the 2nd floor, the elevator must be operated in the upward direction of the 2nd floor, so the service floor can be identified as the upward direction of the 2nd floor. It also sends a card identification signal to a display signal conversion control section, which will be described later. Reference numeral 19 denotes a group management arithmetic unit, which selects an elevator to be serviced from the service floor data signal and instructs the elevator control unit 20 in the figure to operate to the service floor.

In addition, a display signal conversion control unit 18 in Figure 1 outputs identification information of the service elevator (for example, elevator number, etc.) as a service floor display data signal, which generates and outputs a display signal from the service floor display data signal. .

The display signal is generated according to the information message format shown in FIG.

The contents of the card identification code are sent to the sensor panel of the floor from which the destination floor signal is sent via the 16 multiplex output circuits in the figure after generating one display number input from the floor identification control section mentioned above. output the display signal.

The display signal is stored in the group control calculation unit 19 in the figure until the service elevator arrives at the service floor, and the control flow in the group control elevator control system is controlled by periodically or irregularly changing the display signal 18. 3 is a functional flowchart illustrating. 5TPoooo～5TPOOOO

First, an elevator user specifies the destination floor with a portable card and approaches the elevator hall (STPoooo).

Elevator users may specify a destination floor after approaching the landing. The mobile card adds its own card identification code to the destination floor code entered by the elevator user and transmits it as a radio wave (STPlooO).The sensor panel at the landing receives the radio wave from the mobile card, that is, the destination floor code and transmits it as a radio wave. Receives the card identification code and outputs it to the elevator control unit (STP2000), The elevator control unit inputs the destination floor code and card identification code (STP3000), The elevator control unit inputs the input destination floor code and the sensor panel Determine the floor served by the elevator and its direction from the floor, and memorize the card identification code (STP3001).
Selecting an elevator to be put into service on the service floor and making it run to the service floor (STP3002);

The identification value of the elevator in service on the service floor is output as a display code to the previous sensor panel (source of the destination floor code) (STP3003). At this time, the next 5T
Add the card identification code stored in P3001 to the display code. The sensor panel transmits the display code and card identification value input from the elevator control unit as a radio signal (STP2001).The portable card receives the radio signal (STPlooI).The received signal, that is, the card identification code and the portable card Verify your own card identification code (STP1002)
, If the verification results do not match, it is determined that the sent information is not addressed to you (mobile card) and waits for reception again (
Return to STPlooI), if they match, it is determined that the information is sent to you (the portable card), and the display code you entered along with the card identification code is output as an image to the display installed on the portable card. (STP10
04) The elevator user sees the identification value of the service elevator shown in the display contents and waits for the elevator to arrive in front of that elevator (STPOOI).

Next, service display contents according to the present invention will be explained.

Figure 6 (A) shows the layout of the elevator hall, and 2
1a to 21d indicate elevator numbers, respectively. Assume that the landing shown in FIG. 6(A) is on the 1st floor, and an elevator user has registered the destination floor as the 5th floor using the portable card 1 in FIG.

If the service elevator is No. 3 when you approach the landing with this portable card in your possession, then Figure 6 (B)
As shown in the figure, "3" appears on the display 5 on the portable card 1.
Outputs the image. This display is maintained until the service elevator, ie, the third car, arrives at the first floor. Although the above display is an elevator reservation service display, for example, when displaying an arrival display to notify when a service elevator has arrived, the mode of the display image is changed (for example, blinking). That is, in FIG.

19 in the figure manages the service floor display data signal.
Since it is a group management calculation unit, it uses the machine data signals (e.g. elevator position, deceleration information, door information) from the machine control unit 20 to calculate, from the time the service elevator starts decelerating to the service floor until the door opens, By adjusting the signal output, the display mode on the display screen can be changed.

In the embodiment of the present invention, the elevator number is used as the identification value of the service elevator, but the elevator number may be any number as long as the elevator can be identified at the landing.6 For example, change the color of the three-sided frame of the elevator. If this is done, the elevator can be identified, so the color of the three-sided frame of the service elevator may be displayed on the display.

In addition, in the present invention, only the service elevator information sent from the sensor panel is displayed on the display of the portable card with display function, but in addition, when the destination floor is input using the numeric keypad, the contents are displayed. Good too. Furthermore, the information is not limited to the identification information of the service elevator, for example, the waiting time at the landing.

For example, when an elevator user registers a destination floor in consideration of services for visitors, information about that floor (for example, the name of the tenant) may be displayed. good.

In the above detailed description of the present invention, a card is used as a portable display device, but the display device is not limited to a card and may be a wristwatch, for example, as long as it has the above-mentioned functions.

In the group control elevator system according to the present invention, the service display for elevator users is not limited to only inside the elevator hall, that is, the range in which the service display is performed is the range in which radio wave communication is possible, which is determined by the output of radio waves, As long as the physical distance between an elevator passenger carrying a portable card and a sensor panel installed near the elevator landing is within the distance that allows radio communication, the display will apply to all of them. Further, in the present invention, the sensor panel is installed near the landing area, but if it is installed at a location other than the landing area on the same floor, the scope of application of service display will be further expanded.

Further, in the group control elevator system according to the present invention, an elevator user can specify a destination floor from anywhere within the above-mentioned service display application range, and can encourage the service elevator to be put into service. Furthermore, even if a non-elevator user with a portable card is within the above range, the elevator will not provide service unless the user operates the portable card to specify the destination floor. We welcome passengers not only to the elevator landings, but also to
Service display can be easily distinguished within the scope of application.

In addition, the embodiment of the present invention includes a hall call button installed at each hall in a conventional group management elevator control system and a hall call control device that controls registration and deletion of the hall call button, and a destination floor button and a button installed in the elevator. The reason why the destination floor registration control device is not used is that if the elevator user brings the portable card of the present invention, the destination floor can be registered even in a limited place other than the elevator landing or inside the elevator. By registering the floor, it is possible to omit the conventional series of operations of pressing the hall call and then pressing the destination floor button in the elevator. However, if portable cards are not widely used, elevator users who have portable cards will not be able to use the elevators. You may also use the hall call button or the destination floor button inside the elevator. Furthermore, if the portable card of the present invention is handed over to a visitor at the reception desk of a building, elevator users do not need to carry the portable card at all times, and the above-mentioned hall call button and destination floor button inside the elevator can be used. There is also no need to use the group control elevator system of the present invention at the same time.

〔Effect of the invention〕

As explained above, according to the elevator calling device of the present invention, an elevator user can know which elevator to board, so even if the hall is crowded, the user can rest assured that he/she will be able to find the designated elevator without being confused. You can wait for the train to arrive and board the train.

Moreover, the inconvenient phenomenon of unloaded items can be easily eliminated. In other words, if the number of passengers exceeding the capacity of the elevator is waiting at the landing, 1. For example, when an elevator with a capacity of 20 is serving a landing where 30 elevator users are waiting, 20 of the 30 users will be sent to the first elevator. , if the remaining 10 people are notified that they will be placed in the second elevator and the elevator is operated, not only will it be possible to eliminate the problem of leftover luggage, but also the service elevator will be known even outside the elevator platform, allowing smooth boarding. Even when a plurality of elevators are put into service at the same landing, passengers using the elevator at the landing can be boarded without confusing them.

Furthermore, since there is no need to turn on the forecast light at the landing to provide notification, only the minimum arrival notification is required, and display control for one landing becomes easy. Furthermore, if the arrival notification is also displayed on the display of the portable card, there will be no need for any notification device at the boarding point, and the hardware configuration of the entire system will be simpler than before, making it possible to realize a low-cost system.
