Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a notification device for group-controlled elevators.

In the group control elevator, when a hall call is registered, a car is assigned to the car and the elevator responds to the hall call. When there are a large number of passengers waiting at a landing, multiple cars may be assigned to increase transportation capacity.

However, if multiple cars arrive at a floor one after the other, waiting passengers will board the cars separately, but in reality there is a slight time difference between the first car and the last car. It is inevitable that this will occur. As a result, a large number of waiting passengers board the first-arriving car, and the car is operated in a full state, causing great discomfort to the passengers. In addition, waiting customers who miss the car feel uncomfortable.

This invention is intended to improve the above-mentioned problems, and an object of the present invention is to provide a notification device for a group control elevator that allows waiting passengers to be evenly loaded onto a plurality of assigned cars.

The notification device for a group control elevator according to the present invention allocates a plurality of cars according to a hall call,
In addition to detecting this assigned first-arrival car,
The opening of the door of the first-arriving car is detected, and when the opening of the door of the first-arriving car is detected, the presence of a second-arriving car responding to a hall call following the first-arriving car is notified a predetermined number of times.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Although FIG. 2 is for the first machine, similar circuits are used for other machines as well. Fig. 3 shows the parts for the first and second machines, and the part for the third machine is omitted. Furthermore, the numbers A to C appended to the end of the symbols indicate those for the first to third machines, respectively. However, in order to avoid complexity, some parts of the explanation are not marked A to C.

In Figure 1, 1 to 5 are floors 1 to 5, a to c
are the cars of No. 1 to No. 3, respectively.

In Figures 2 and 3, (+) and (-) are DC power supplies, and 1Aa, 1Ab to 5Aa, and 5Ab are terminal downbound calls that are closed when a car is assigned to a downbound call on the 1st to 5th floors, respectively. Assigned relay contact, 1Ba,
1Bb to 5Ba, 5Bb are car position contacts that close when the car reaches a certain distance from the 1st to 5th floors, 1Ca to 5Ca are car position contacts that similarly open, and 1D, 1E to 5D, and 5E are energized. This is a first-arrival car detection time relay that operates immediately and returns after a certain period of time when it is de-energized.
Eb~5Da, 5Db, 5Ea, 5Eb are normally open contacts, 1Dc~5Dc are also normally closed contacts, 1F~5F
are the speakers installed in the landings on the 1st to 5th floors, respectively, 6a is the door open detection relay contact that opens when the car door opens, 6b is the door open detection relay contact that also closes, and 7 is terminal X and terminal A1 ~ When a voltage is applied between each of A5, a synthesized audio signal saying "Unit 1 will arrive next" is sent to terminals X and B.
When a voltage is applied between each of terminals 1 to B5, a synthesized voice signal saying "Unit 2 will arrive next" is generated, and when a voltage is applied between each of terminals C1 to C5, The synthesized audio signal saying "Unit 3 will arrive next" is sent to terminal Y and terminal F1.
This is an automatic broadcasting device that broadcasts between each of the terminals (to the terminals with the same numbers).

Next, the operation of this embodiment will be explained.

Now, as shown in Figure 1, Unit 1 a is on standby without direction on the 2nd floor 2, Unit 2 b is on standby without direction on the 1st floor 1, and Unit 3 c is descending near 3rd floor 3 by car call. shall be.

At this time, a call to get off the platform was registered on the 4th floor 4.
If this is assigned to machine No. 1 a by a well-known assignment circuit (not shown), assigned relay contacts 4AaA and 4AbA are closed. If the number of customers waiting for the down-bound call on the 4th floor increases and it becomes impossible for one car to handle the call (as detected by a well-known waiting-passenger number detection circuit), the number of customers waiting for the down-bound call on the 4th floor increases. is additionally allocated to other baskets. Now, assuming that it is Unit 2 b, assigned relay contact 4AaB is closed.

When the first car a reaches a certain distance before the second car b, the car position contact 4BaA closes. At this time, the car position contact 4CaB is still closed, so (+)-6aA-4AaA-4BaA-4
The circuit CaB-4DcB-4DA-(-) energizes and operates the first-arriving car (car No. 1) detection time relay 4DA on the fourth floor, and self-holds by closing the contact 4DaA. Contact 4DbA is also closed. When the first car a arrives at the fourth floor 4 and the door opens, the door open detection relay contacts 6bA and 6bB close, and the contact 6aA opens. When the contact 6aA is opened, the time relay 4Da is deenergized, but the contact 4DbA is closed for a certain period of time. As a result, (+)-6bA-4DbA-B4-
A voltage is applied between terminals B4-X by the circuit X-(-). The automatic broadcasting device 7 then operates and broadcasts from the speaker 4F on the 4th floor that ``No. 2 aircraft will arrive next.'' As a result, passengers waiting to board the crowded No. 1 train A know that the No. 2 train B will arrive soon, so they will have to wait for it. When the time limit of time relay 4DA expires, contacts 4DaA and 4DbA are opened. Unit 1 a
When the door starts to close, door open detection relay contact 6
aA is closed, contacts 6bA and 6bB are opened, and the state returns to the initial state.

If No. 2 car b arrives before No. 1 a in response to a down call from the 4th floor, car position contact 4Cab of No. 2 car opens before contact 4BaA, so the car position of No. 1 car position Even if contact 4BaA closes, first-arrival car detection time relay 4DA of car No. 1 does not operate. In this case, a similar circuit operates the first-arrival car detection time relay 4DB (not shown) of the second car, and the contact 4DbB closes, (+) -6bB-
By the circuit of 4DbB-A4-X-(-), terminal A
A voltage is applied between 4-X. Now, the message "Unit 1 will arrive next" is broadcast from the 4th floor speaker on the 4th floor. Also, contact 4DcB is opened.

Also, when the 4th floor down call is assigned to the 1st car and 3rd car, and the 1st car arrives first, (+) -6aA - 4AbA - 4AaC - 4BbA - 4
The circuit of CaC-4DcC-4EA-(-) operates the first-arrival car (car No. 3) detection time relay 4EA,
Contact 4EbA is closed and (+)-6bA-4EbA-
A voltage is applied between terminals C4-X by the circuit C4-X-(-). Now, speaker 4 on the 4th floor
F broadcasts, ``Unit 3 will arrive next.''

It goes without saying that the same applies to floors other than the 4th floor 4, and the same applies to inbound calls from the landing.

Note that it is also possible to implement as follows.

(A) Instead of installing speakers 1F to 5F in the landing area, one speaker is installed in the car.

(b) When broadcasting the arrival of the last basket, if you also broadcast the number of seconds it will take to arrive, it will be more helpful.

(c) The operation shown in Figure 2 is processed by a program calculation using a microcomputer or the like.

(d) Applies to 3 or more cages.

As mentioned above, the invention of this application is characterized in that when a plurality of cars are assigned to one landing call, the presence of a following car is notified to the landing when the door of the first car opens. It is something.

In the case of this invention, the reason why a plurality of cars are assigned is that the number of passengers waiting at the landing cannot fit into one car. The control device can detect in advance whether or not the train will make it through, but waiting customers will only know when the door is opened. Since the timing of the notification of the later arriving car is timed with human detection, the notification can be made effectively, giving a great sense of relief to waiting customers.
Also, this sense of relief allows you to avoid concentrating on one basket and achieve equalization.

Further, although it is possible to notify the last arriving car in advance, the direction of the last arriving car may be reversed depending on the situation thereafter. This may cause unnecessary confusion to waiting customers. However, according to the present invention, since the next arriving car is notified after the door of the first arriving car is opened, there is also the effect that the above-mentioned confusion does not occur.
