Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator control device that operates a plurality of elevators, and in particular, when a hall call is registered, it is immediately determined which car will respond. This invention relates to an elevator control device that uses a method (J117 hour forecast method) to notify the arrival forecast light by lighting up the arrival forecast light.

[Conventional technology]

Conventionally, the prior art of the real-time forecast type elevator is disclosed in Japanese Patent Laid-Open No. 54-27151.

Figure 2 shows the configuration diagram of the control device used when two elevators service the 1st to 5th floors of a 5-story building using the conventional instant forecast system. The rising landing button for the floor, 2 is the rising button number R1 for each landing button from IH to 4H.
1 to 14 are input to the group management device, and 3 is the control device 3A for the A and B cars.

3B is a control device, 4 is a forecasting device that predicts the arrival of cars at the landing, and hall lanterns 41A to 44A and 41B to 4 corresponding to the 1st to 4th floors correspond to cars A and B.
4B (Only the rising hall lantern is shown here.

), and lighting signals 31A to 34A corresponding to the 1st to 4th floors output from the A machine control device 3A are applied to the ascending hall lanterns 41A to 44A for the 1st to 4th floors of the A machine. Along with Unit B 1-4111
The lighting signals 3 corresponding to the 1st to 4th floors outputted from the B machine control device 3B are sent to the lanterns 41B to 44B for the 9th hall for f.
1B to 34B can be added.

In the instant forecast system with the above configuration, for example, when the fourth floor climbing platform button 4H is pressed, the fourth floor ascending phase signal 14 is sent to the group control device 2, and in this group control device 2, A, B9-
fi Calculate which car should respond. If the calculation result determines that, for example, aircraft No. A is to respond, the group control device 2 sends a message to the control device 3A of No. A 4.
A floor ascending hall call assignment signal 2A is transmitted, and a fourth floor ascending hall lantern lighting signal 34A is transmitted from the control device 3A.
By sending out the 4th floor ascending hall lantern 44
Light up A.

Therefore, the passenger who pressed the 4th floor ascending platform button 4H will receive Atel.
! Knowing that A! will respond, A! Waiting for the basket to arrive in front of the shore. When Aircraft A arrives, the call for boarding is canceled, and once passengers have boarded and alighted, the doors are closed and the hall lantern 4H is turned off.

In addition, with this type of elevator, the hall call is not canceled even if another car first arrives at the hall call floor to which the hall call is assigned, and the hall call assigned to that car is always serviced. I will do it.

Please note that for the first car to arrive at the car call, the call will be canceled only within the city, and normal service will be provided in other areas.

[Problem that the invention seeks to solve]

In the conventional control device as described above, as mentioned above, there are cases where another car arrives first (this is called a failure of the prediction) even when the prediction car arrives. In this case, there is no problem for passengers who notice the arrival of the first-arriving car and get on that car because they receive normal service, but passengers who notice the arrival of the first-arrived car too late or who carry large baggage and board the forecasting car do not experience any problems. Passengers who were unable to move immediately because they were waiting in front of the train had problems such as distrust and dissatisfaction with the instant forecast because the service was delayed even though the forecast was waiting in front of them.

This invention was made in order to solve the above-mentioned conventional problems, and is an elevator system that does not cause distrust or dissatisfaction among passengers waiting for the platform when the instant forecast fails to occur. The purpose is to provide a control device.

[Means for solving problems]

The elevator control device according to the present invention includes means for detecting that a car other than the forecast car arrives at the forecast floor first;
A means is provided for detecting that a new car call has been registered in the first-arriving car on the forecast floor, and a means is provided for causing the door of the first-arriving car to close once and then reopen when both detection means of the parenthesis are activated. It is.

[Effect]

In this invention, when both of the detection means are activated, the door of the first-arriving outside car is once closed and then reopened, delaying the start of the door, and thereby preventing the arrival of the first-arriving car from passengers who are delayed in noticing the arrival of the first-arriving car. Increase usage opportunities.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, 50 is a door control relay that issues a door close command when energized and issues a door open command when de-energized, 51 is a door reversal command relay, and 52 is a door reversal memory relay. , time relay for setting door non-interference time (
connected between the DC power sources (+) and (-) via the normally closed contact 53a of the door opening button 54 (not shown), the door safety switch 55, and the normally closed contact 51c of the door reversal command relay 51;
Further, a series circuit of a normally open contact 58a of a running relay (not shown) which is energized during running and a self-holding contact 50a of the door control relay 50 is connected in parallel to the series circuit of each of the contacts 53as54, 55, 51c. has been done.

In addition, the door reversal command relay 51 includes a normally closed contact 521J of the door reversal memory relay 52, a normally closed contact 56b of the travel relay, a normally open contact 57a of the forecast error detection relay (not shown), and a new The normally open contact 58a of the car call registration detection relay (not shown) and the door closed end are separated by a certain distance (for example, 50a
+m) is connected between the DC power sources (+) and (-) through a door close position switch 59 that closes when the door is fully open. Then, the series circuit of the door open position switch 60, which opens the circuit, and the self-holding contact 51a of the door reversal command relay 51 is connected in parallel. Furthermore, the door reversal memory relay 52 is connected to the normally open contact 51 of the door reversal command relay 51.
The normally open contact 51b is connected to a series circuit of the normally closed contact 56c of the travel relay and the self-holding contact 52a of the door reversal memory relay 52 in parallel. It is connected to the.

Next, the operation of this embodiment configured as above will be explained.

While the elevator is running, (+) - contact, rf, 5.6 a
The door control relay 50 is self-held by the closed circuit of - contact 50a - relay 5O (-), and the time relay for setting the non-interference time of the door is also energized, and its normally closed contact 53a is closed.

In such a state, when the car stops at a landing call or a floor called by a car call, the normally open contact 56a of the traveling relay
Since the door is opened, the door control relay 50 is deenergized and a door opening command is issued. As a result, when the door is fully opened and about 4 seconds have elapsed, the time limit of the door non-interference time setting time relay expires and is deenergized, and its normally closed contact 53a closes.

Therefore, the door control relay 50 is energized by the closed circuit of (+)-contact 53a-door open landing button 54-door safety switch 55-contact 51e (), and issues a door close command.

As is well known, if there is a call for the receiver of the basket,
The car runs, and if there is no call, the car closes its door and waits.

Now, if another car arrives at the floor where the forecast car is located, the forecast failure detection relay is energized and its normally open contact 57a is closed. Then, when a passenger gets into the first car and registers a new car call, the car call 1 registration detection relay is energized and its normally open contact 58a is closed. As a result, (+)-contact 57a-contact 58a-door close position switch 59-contact 56b-contact 52b-relay 5l-
The door reversal command relay 51 is energized by the (-) closed circuit, and is self-maintained by its contact α51a.

Then, by opening the normally closed contact 51c, the door control relay 50
is deactivated and issues a command to open the door, causing it to open. Note that when the door is opened by a door comparison command, the door non-interference time is reset.

On the other hand, since the normally open contact 51b is closed, the (+)-contact 5
The door reversal memory relay 52 is energized by the closed circuit of the 1b-relay 52-(-), and when the 0 door, which is self-held by closing its contact 52a, is fully opened, the door open position switch 60 is opened.
In addition, since the normally closed contact 52b is opened, the door reversal command relay 51 is deenergized and its normally closed contact 51c is closed.

Thereafter, the door is closed by the door closing operation described above, and the car starts traveling. Then, when the first car runs, the normally closed contact 56b of the running relay opens, so the door reversal memory relay 52 is deenergized.

As mentioned above, in this embodiment, when the forecast car goes up, another car arrives first with a car call, this is detected by the forecast failure detection relay, and a new car call is registered in the first car. When detected by the car call registration detection relay, the door of the first car is closed and then opened again.
Since the first-arriving car starts later than usual, even if a passenger who was waiting for the forecast car notices the arrival of the first-arriving car late, that passenger can still use the first-arriving car with plenty of time. , distrust and dissatisfaction with the forecast can be immediately resolved.

In addition, in the above embodiment, only the ascending direction has been described, but the same can be applied to the descending direction. Furthermore, when the door is opened again in response to a door reversal command, it is also possible to operate a hall lantern, chime, etc. Furthermore, the method of the present invention is not effective on all floors, but may be implemented on specific floors, such as terminal floors, main floors, or floors where visitor indicators are installed.

〔Effect of the invention〕

As explained above, according to the present invention, in an instant forecast type elevator, when a forecast error occurs, instead of operating the first car normally, when a new car call is registered for the first car on that floor, Since the door is reopened after closing to prevent passengers from missing the train, it is possible to reduce distrust and dissatisfaction among passengers waiting at the boarding point.
