Detailed Description of the Invention TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates to the reservation display control of notifying the arrival of the car of an elevator.

[Prior art]

Generally, an elevator hall is provided with a hall call button and a reservation lamp (hall lantern) for each car,
When the user presses the hall call button to make a hall call , the reservation lamp corresponding to the optimum car is turned on, and a warning is given that the car will arrive soon. In this case, various methods have been proposed for issuing the forecast. For example, Japanese Examined Patent Publication No. 56-43988 describes that a forecast is not issued when the arrival time of the optimum car for a hall call is a predetermined time or more, but a forecast is issued when the arrival time is within a predetermined time. Japanese Examined Patent Publication No. 54-5583 describes that a forecast is not issued when the assigned car positions are separated by a predetermined value or more and a forecast is issued when the assigned car positions are closer than the predetermined value.

Further, Japanese Examined Patent Publication No. 62-269871 does not issue a forecast when the assigned car faces in the opposite direction to the reservation direction, but only when the car faces the same direction as the reservation direction. It is described to issue. Further, in Japanese Examined Patent Publication No. 6-255913, when the difference between the car with the best allocation calculation and the car with the next run is small, it is not immediately known which car arrives first.
It is described that the lighting of the reservation lamp is delayed.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the overall configuration of an elevator control device according to the present invention. In FIG. 1, unit control devices 10, 20, and 30 are respectively connected to the group management control device 1 via an operation network L1. Further, a car 11 is provided corresponding to the machine controller 10, and the car 11 is controlled by the machine controller 10. Although not shown in the figure, the machine controller 20,
Cars are provided corresponding to the respective cars 30, and each car is controlled by the machine control devices 20 and 30.

The car 11 is provided with a car call button 12, and the car call button 12 is connected to the machine control device 10. In addition, a forecast light 101 is provided in the elevator hall on each floor so as to correspond to the car 11.
01 is also connected to the machine control device 10. The number of machine control devices connected to the group management control device 1 may be one, two, or four or more.

The car 11 is provided with an information guide device 14 having a speaker 13 for notifying arrival of an elevator and the like and an LED display panel. Similarly, in the elevator hall on each floor, the speaker 103 and the information guidance device 10 are also provided.
4 are provided. The speakers 13 and 103 and the information guidance devices 14 and 104 are connected to the information network L.
It is connected to the group management control device 1 via 2.

Hall call buttons 105, 205, ... Are provided in the elevator halls on each floor (here, the 1st to 9th floors).
, 905 are provided, and these hall call buttons are connected to the group management control device 1 via the driving system network L3. The hall call buttons 105, 205, ..., 90
It is also possible to connect 5 to the group management control device 1 via the machine control device 10 without directly connecting it to the group management control device 1. Further, the number of hall call buttons is not limited to one on each floor, and there may be a plurality of hall call buttons.

In the above structure, the hall call button 105,
When any of 205, ..., 905 is pressed and a hall call is generated, the group management control device 1 causes the position and direction of each car sent from each unit control device 10, 20, 30 by communication. , It is assigned to the elevator of the optimum car for the hall call, taking into consideration the situation of the car call and the congestion degree in the car . For example, when it is determined that the car 11 is the optimum car, the reservation light signal or the allocation signal is transmitted to the car control device 10 that controls the car 11.

By the way, a user calls a hall on a certain floor.
If there is a car immediately after leaving the floor when you do, the car will normally be assigned to that car. This is normally between each unit controller and group supervisory controller.
This is because communication is performed at 9600 bps, and it takes about 0.1 ms to transmit one byte , which causes a communication delay between the machine control device and the group management control device. For example, as shown in FIG. 2, when the car is heading to the 8th floor 7th floor, when the user who is on the 7th floor has a hall call as a go upstairs, Unit control apparatus (Fig. The upper half of 2) can immediately recognize that the car is on the 8th floor, but due to the communication delay described above , the car is still on the 7th floor on the group management control device side (lower half of Fig. 2). Recognize that
Assign it to the car. However, in reality, the car has already passed the 7th floor, so you will have to go up to the upper floor and return, which will cause a long wait.

In this case , therefore, in such a case, the hall call is not immediately assigned after the hall call , but the hall call is held for a certain period of time and the assignment of the car is reviewed. That is, the cars moving from the 7th floor to the 8th floor as shown in FIG. 2 are excluded from the allocation. As a result, the allocation is transferred to another car, avoiding long waiting for users
it can.

Next, another embodiment will be described with reference to FIG. In FIG. 3, 10, 20, and 30 are elevator cars, and the first car 10 is at the bottom floor, 2
Car 20 of Unit 3 is on the top floor Car 30 of Unit 3
Are located one and two floors below the top floor, U1 and U respectively
It is assumed that the service is provided in the driving direction of 2, U3. Now 3
When a hall call H1 occurs on the floor of Unit 1, Unit 1 is C
It has a car call from 100 to C102, and it takes about 50 seconds to service the H1 hall call. Unit 2 is assigned an H2 hall call, and it takes about 70 seconds to service the H1 hall call because it descends once and then returns. On the other hand, since Unit 3 only has the car call C103 on the top floor, it takes about 20 seconds to service the H1 hall call. Therefore, the group management control device is assigned to the third unit.

However, when the reservation lamp is turned on by allocating it to the third car, the third car has just departed from the hall call generation floor of H1, so the user feels disbelief that another elevator is stopped. Become.

Therefore, in the present embodiment, when the allocation becomes No. 3 when the hall call for H1 occurs, the reservation lamp is turned on by delaying the lighting for about 3 seconds so that the user may feel distrust. To reduce.

FIG. 4 is a flow chart of reservation reservation processing in the elevator control device according to the present invention. First, when a hall call is generated, it is registered (step S1), a group machine evaluation calculation is performed, and an optimum machine is detected (step S).
2). Each unit remembers the last departure floor and the time elapsed since the departure, and determines whether the last departure floor of the optimum unit is the same as the hall call generation floor (step S3). If they are the same, the elapsed time is checked to determine whether or not a certain time has passed (step S4). Then, if the predetermined time or more has not elapsed, the process returns to step S2 and the group machine evaluation calculation is performed again .
It If it is determined in step S4 that a certain time or more has passed, and if it is determined in step S3 that it is not the same as the hall call generation floor, it is assigned to the optimum number (step S5). Then, a guide such as "please wait" is displayed on the display in the elevator hall (step S
6) Further, the reservation lamp is turned on (step S7).

FIG. 5 shows the guide in the elevator hall display.
Is a concrete example displaying . Elevator door 201
“Please wait for a while” is displayed on the display 202 at the top of the. A hall call button 203 is provided beside the door 201, and a reservation lamp 204 is provided above the display 202. Note that the guidance display can be done by voice .

【The invention's effect】

As described above, according to the present invention, the elevator is prevented from being assigned to the elevator machine immediately after the departure, so that the elevator user does not feel distrust and the elevator user does not feel distrust. Can be used comfortably .
