DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an apparatus for predicting the arrival of a car to a passenger waiting at an elevator.

[Prior Art] In the elevator allocation group management system, when a hall call is registered, one of a plurality of cars is allocated to the hall call. When the car is assigned, the arrival forecast light of the floor where the hall call is registered is turned on to display that the car has been assigned and the driving direction thereof to guide the waiting passengers.

FIG. 4 shows, for example, JP-A-52-131345 and JP-A-56.
It is a hall front view which shows the arrival prediction device of the conventional elevator hall shown by -65780.

In the figure, (1) to (3) are hall doors of Units 1 to 3,
(4) (5) is a hall button installed on the wall of the hall, which has up and down buttons for registering hall calls common to Units 1 to 3, and (6A) to (6C) are hall doors (1), respectively.
~ (7A) ~ (7A) ~ (7) ~ (7)-(7)-(7), which is installed above (3) and lights up when the car arrives at this floor in the up direction.
C) is a down light of the arrival prediction light which is also turned on when arriving in the down direction.

The conventional elevator hall arrival forecasting device is configured as described above. For example, if the up button of the landing button (4) is pressed to register an up call and the car of the first car is assigned to this, the car of the first car of the first car is assigned. Arrival warning light (6A)
Lights up and predicts that Unit 1 has been assigned.

Various proposals have been made for this forecast display,
The above-mentioned Japanese Patent Laid-Open No. 52-131345 discloses that when a predetermined condition is reached after a car is assigned to a hall call, a forecast is displayed at the hall, and the cage for which the forecast is displayed arrives on that floor. This is to increase the probability of doing. Also,
Japanese Patent Application Laid-Open No. 56-65780 discloses an arrival prediction lamp in which the current flowing through the arrival prediction lamp is changed in accordance with the number of arrival prediction lamps for predicting and displaying a car responding to a hall call. Even if there is a limit to the power supply capacity of the, the forecast display will be made immediately to the passengers waiting at the landing.

[Problems to be Solved by the Invention] In the above-described conventional arrival prediction device for an elevator hall, since the forecast display is not performed until a predetermined condition is satisfied after the hall call is registered, the hall button (4 )
Immediate arrival warning lights (6A) to (6C) even if (5) is pressed
There is a problem that (7A) to (7C) do not light up. In addition, since the current flowing through the arrival prediction lights (6A) to (6C) (7A) to (7C) is limited, the lighting intensity of the lights decreases, and the arrival prediction lights (6A) to (6C) (7A) ~ There is a problem that it is difficult to determine whether or not (7C) is lit.

The present invention has been made to solve the above problems, and an arrival forecasting apparatus for an elevator hall that can immediately display a forecast when a hall call is registered and that does not reduce the light intensity of the arrival forecast light. The purpose is to provide.

[Means for Solving Problems] The elevator hall arrival prediction device according to the present invention stores the number of arrival prediction lights that have already been turned on for each car, and the number of arrival prediction lights in the car exceeds the planned number of lights. When a call is assigned, the landing call is reassigned to issue a command to assign to a car other than the above-specified number of lights and to turn on the arrival warning lights of cars that are less than the above-specified number of lights. It is the one.

[Operation] In the present invention, since the hall calls are assigned to the cars that do not exceed the planned number of arrival forecast lights, when the power supply capacity for the arrival forecast lights is limited for each car, the hall calls Even if the arrival prediction light is turned on with registration, the brightness of the arrival prediction light does not decrease.

[Embodiment] FIGS. 1 to 4 are views showing an embodiment of the present invention.
FIG. 2 is an overall configuration diagram, FIG. 2 is a block diagram of a microcomputer (hereinafter referred to as a microcomputer) portion, FIG. 3 is a flowchart showing the operation of the microcomputer, and FIG. 4 is the same as the conventional device. The same parts as those of the conventional device are designated by the same reference numerals. The figure shows the upward call of Unit 1.

This embodiment is constructed as shown in FIG. That is, when the hall buttons (4) and (5) (uplink buttons) are pressed, this is registered by the hall call registration means (11),
An assignment calculation means (12) selects a car most suitable for responding to the hall call and assigns it to the hall call. The number-of-illuminations determination means (13) reads the number of already-illuminated arrival forecast lights stored in the storage device (14) and determines whether the number of arrival forecast lights of each unit exceeds the planned number by new allocation. If the number is less than the planned number, the arrival forecast lamps (6A) to (6C) of the assigned units are instructed to be lit via the lighting command devices (15A) to (15C). Also, if the number of lights exceeds the planned number,
Reassignment is instructed by the assignment review command means (16),
Reassignment is executed by the assignment computing means (12) to assign a car other than the above assigned car. As a result, a car whose number of lights is less than or equal to the planned number is assigned, and the arrival forecast lamp of the car is instructed to be lighted, and at the same time, stored in the storage means (14).

In FIG. 2, (19) is a microcomputer, which has a CPU (19A), a memory (19B), an input circuit (19C) and an output circuit (19D), and the input circuit (19C) has a landing button (4) ( 5) is connected, and the output circuit (19D) is connected to the No. 1 to No. 3 lighting command devices (15A) to (15C).

Next, the operation of the above embodiment will be described with reference to FIG.
This program is stored in the memory (19B) of the microcomputer (19). (However, well-known parts are not shown).

Now, the hall of Fig. 4 is the hall on the 10th floor, and the hall button (4)
If (uplink button) is pressed, an upcall on the 10th floor is registered, and one car to respond to is assigned. At this time, it is assumed that the car assigned to the hall call was the first car.

Next, when Unit 1 is assigned to the 10th floor inbound call, 1
It is determined whether the arrival forecast light (6A) can light up on the 10th floor of the Unit. Here, it is assumed that the number of arrival prediction lights that can be turned on per car is limited to five. In addition, Unit 1
Already assigned to hall calls on floors other than the 10th floor, and already 5
It is assumed that the arrival forecast lights of the respective units are lit, the number of the second unit is three, and the number of the third unit is one.

First, in step (21), it is determined whether or not it is the allocation for the first machine. Since it is the allocation for the first machine at present, the process proceeds to step (24), where the number of the first machine already turned on (5
Individual) from the memory (19B). In step (27), it is determined whether the number of lights (5) is less than or equal to a value (4) obtained by subtracting 1 from the planned number (5). Since the number of lights is 5, the process goes to step (28) to output the allocation review signal. Now, with regard to the allocation of uplink calls on the 10th floor, excluding Unit 1 is recalculated and assigned to either Unit 2 or Unit 3. Here, it is assumed that it is assigned to Unit 2.

In the next calculation cycle, since it is the allocation for Unit 2,
Step (21) to step (22) to step (2
Proceed to 5) and take out the number (3) that Unit 2 is already lit, and in Step (27), the number (3) that is lit is less than the value (4) that is obtained by subtracting 1 from the planned number (5). Is determined. Since the number of lights is three, the process proceeds to step (29), the lighting permission signal is output to the No. 2 lighting command device (15B), and the No. 2 up light (6B) is turned on. Then, in step (30), 1 is added to the number of lights of Unit 2 (three), and the result is stored in the memory (19B).

As a result, in response to an upward call on the 10th floor, the upward light (6B) of Unit 2 will light up, and the car that will serve the waiting passengers on the 10th floor will be immediately displayed. In this way, a car capable of lighting the arrival forecast light is assigned to the hall call, and the arrival forecast light of the car is lit, so that the waiting passengers at the hall press the hall buttons (4) and (5), You can immediately see the car that serves that floor.

In the embodiment, after performing the allocation calculation, it is determined whether or not the arrival prediction light can be turned on. However, whether or not the arrival prediction light can be turned on is calculated in advance, and then the allocation calculation is performed. Can also be configured to do.

Further, in the embodiment, three elevators are installed, but the same operation can be obtained regardless of the number of installed elevators.

[Effects of the Invention] As described above, according to the present invention, when a hall call is assigned to a car that exceeds the planned number of lights, a command for reassigning the hall calls is executed to assign a car other than the cars that exceed the planned number of lights. Since the arrival forecast lights of the cars that are less than the planned number of lights are turned on, the forecast display can be displayed immediately when the hall call is registered, and it is possible to prevent the light intensity of the arrival forecast lights from decreasing. There is an effect that the service for waiting customers can be improved.
