Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an elevator control device for efficiently responding to an elevator hall call.

(Prior Art) In high-rise buildings and skyscrapers, a group control elevator that operates efficiently is installed in a plurality of passenger elevators. Among group-controlled elevators, when a passenger presses a hall button, elevators that can provide optimal service for the pressed hall call are displayed by lighting hall lanterns near the hall entrances (hereinafter referred to as "elevators"). is called service reservation display) is called service reservation type group management. This service reservation type group management is most commonly used in nearby high-rise buildings and skyscrapers.

Here, responses to elevator hall passengers are generally made by detecting whether or not a hall call is registered, that is, the presence or absence of a hall call, even in group control elevators. .

That is, it is determined whether a passenger is waiting in the elevator hall based on the presence or absence of a hall call, and the elevator is made to respond. On the other hand, people who come to the elevator hall generally first press the hall call button in the direction they want to go (up or down).

After confirming that the hall call is registered (the hall call button lights up), wait for the elevator that responds to the hall call to arrive. Passengers waiting at the platform take the elevator.
If the user leaves the hall or waits for a long time for the elevator to arrive, the user may use the first flight of stairs to move to another floor.

In such a case, the hall call remains registered even though there are no passengers in the elevator hall scheduled to board an elevator operating in the direction of the registered hall call. (This condition is hereinafter referred to as "push-and-run.")

(Problems to be Solved by the Invention) Even in the case of a push-and-run, the elevator arrives and opens its doors in response to the registered hall call, but there are no passengers waiting for the elevator in the elevator hall. For this reason, the elevator responded in vain, and the elevator
From the perspective of operation, this response is completely meaningless.

If push-and-runs occur frequently, the elevator operation will involve many unnecessary responses, which will actually increase the waiting time of passengers waiting in other elevator halls.

Here, the presence or absence of passengers waiting in the elevator hall can be automatically detected by installing, for example, an energy wave receiving and transmitting device on the ceiling of the elevator hall. However, on intermediate floors of elevators (floors other than the upper and lower floors), there are generally two types of hall calls: upward and downward, and it is difficult to detect the difference between waiting passengers for each. Can not.

The object of the present invention is to
To provide an elevator control device which prevents the elevator from making unnecessary responses when passengers leave a hall.

[Structure of the invention]

(Means for Solving the Problem) A display means is provided at the hall for displaying a reservation that the corresponding elevator will service the hall call registered by the hall call registration means for registering the hall call of the elevator.

A detection means for detecting the presence or absence of passengers in the hall is provided at the entrance/exit of the elevator whose reservation is displayed by the display means,
An alarm means is provided on the landing side for issuing an alarm for a predetermined period of time when a passenger is not detected by the detection means. When the detection means does not detect a passenger at the hall within a predetermined time, the hall call registration by the hall call registration means is deleted by the hall call registration deletion means.

(Function) The display means displays a reservation on the hall that the corresponding elevator will serve the hall call registered by the hall call registration means. The detection means detects the presence or absence of passengers at the entrance/exit of the hall of the elevator whose reservation is displayed, and if no passengers are detected, the alarm means on the hall side issues an alarm for a predetermined period of time, and if no passengers are detected at the hall within this predetermined time. The hall call registered by the hall call registration means is deleted by the hall call registration deletion means.

(Example) Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is an embodiment based on the present invention, showing a circuit configuration for one hall call, and the same applies to other halls. In addition, the number of elevators is three, which is an example of an A car, a B car, and a C car.

7 is a hall call button, 8 is a hall call relay, 8-1a,
8-2a is the normally open contact of 8, 9 is the hall call registration relay,
9”la, 9-2a, 9-3a are 9 normally open contacts,
10 is a call cancellation normally closed contact when answering a hall call, 1l-Aa
, 1l-Ba.

1l-Ca is a normally open contact that operates when a service reservation is displayed for the A, B, and C machines, respectively.

L2-Ab, 12-Bb, and l2-Cb are sensors 4-A installed at the entrance and exit of each aircraft to detect passengers.
, 4-B.

This is a normally closed contact when 4-C is activated. 13 is a hall call alarm timer, 13-1b is 13 normally closed contacts, 14 is a hall call alarm relay, 14-1a is 14 normally open contacts, 1
5 is a re-registration hall call detection relay, 15-1b is a normally closed contact of 15, 16 is a flicker relay for hall call alarm, 16
-1b is 16 normally closed contacts, and 17 is a hall call registration light. P and N are control power supplies.

First, when an elevator user presses the hall call button 7, the hall call relay 8 is energized only at that time. relay 8
When energized, its contact 8-18 closes and the 1 hall call registration relay 9 is energized only at that time, so its contact 9-18 closes.
18 is closed and relay 9 is self-holding. When relay 9 is energized, its contact 9-38 closes and hall call registration light 17 is activated.
lights up.

Here, if the service reservation is displayed on machine A, contact 11
-Aa is closed and if sensor 4-A is operating, contact 12-Ab is open. For this reason, registration of elevator hall calls is similar to general elevator call registration, and the elevator responds to hall calls as usual. When a response is received, the contact 10 opens and the hall call registration relay 9 is no longer energized, so the contact 49-3a is opened and the registration light 17 is turned off.

However, when the service reservation is displayed on Unit A and 1l-Aa is closed, if sensor 4-A is not working, contact 1
Since the contact 2-Ab is closed and the contact 9-23 is also closed, the timer 13 is energized and starts counting a predetermined time for the hall call alarm. In addition, the hall call alarm relay 14
Since the contact 14-1a is closed, the flicker relay 16 is energized. When the relay 16 is magnetized, its contact 16-1b opens and closes, and the registration light 17 flickers.

If the elevator user presses the hall call button 7 again during that time, the relay 8 is energized only during that time, so the contact 8-28 is closed and the re-registration hall call detection relay 15 is energized. This opens the contact 15-1b and the timer 13 is reset once, but if the elevator user stops pressing the hall call button 7, it starts counting again. In this case, when an elevator user stands in front of the entrance of elevator No. A, sensor 4-A is activated, 12-Ab is opened, and timer 13 is reset.

However, if the elevator user presses the call button 7 again or does not stand in front of the A elevator, the timer 13 will start for a preset period of time (for example, from 5 seconds to 1 minute).
0 seconds), the coil of the timer 13 is energized and its contact 13-1b is opened. Therefore, the relay 9 is no longer energized, the hall call is forcibly erased, and its contact 9 is energized.
-38 opens and the hall call registration light 17 goes out. At that time, the contacts 9-18 are also opened, so the relay 9 is not energized again unless the call button 7 is pressed again to energize the relay 8 and the contacts 8-18 are closed. Further, since the contact 9-28 is also opened, the timer 13 is reset.

FIG. 2 shows an elevator hall on an intermediate floor near the entrance/exit of an elevator hall according to an embodiment of the present invention. First, passenger 1 who has come to the elevator hall presses the downward call of the hall call buttons 2. If elevator B is the best option, the hall lantern 3 of car B will be pressed.
The lower part of B lights up, and the service reservation shown in the lower part is displayed. Passenger 1 waits for the arrival of the elevator in front of Car B, so an area where the presence or absence of passengers can be detected by the energy wave receiver/transmitter 4-B, which is a sensor installed at the top of the landing of Car B, to detect the presence or absence of passengers. (Hereinafter, referred to as the detection area) 5-B enters, and the sensor 4-B operates.

Here, if passenger 6, who also came to the elevator hall, presses the upper call of the hall call buttons 2 and leaves the elevator hall after the service reservation for machine A is displayed, the detection of machine A There are no passengers waiting in area 5-A, and sensor 4-A does not operate.

In this way, whether there are passengers actually waiting in the elevator hall or not can be clearly distinguished by the presence or absence of the sensor 4's operation. When the sensor 4-8 is in operation, the lower call of the hall call buttons 2 for the service reservation display of car B remains registered.

On the other hand, since the sensor 4-A is not operating, the call to the upper direction of the hall call buttons 2 for the service reservation display of car A is considered to be a push-and-run. This push-away upward call is for a predetermined period of time (for example, 5 to 10 seconds)
If an alarm is issued in the elevator hall and the passenger is still not detected, i.e. sensor 4-A is not activated, the call will be forcibly deleted. - Even if you are not waiting in front of the elevator, if you re-register the hall call within this predetermined time or wait in front of the elevator where the service reservation is displayed, the call will not be forcibly deleted. , the elevator responds.

According to the above, after registering a hall call, if there are no passengers attempting to go in the direction of the hall call, the hall call will be flickered for a predetermined period of time to issue an alarm, and during that time, if there are actually passengers If this happens, you can either register it again or have it automatically detected by the sensor.

However, in the case of a push-and-run where there are no actual passengers, no passengers are detected and the hall call is forcibly erased. reduce waiting time for passengers.

Although one embodiment of the present invention has been described using a relay sequence circuit, it is of course possible to configure this using micro combi coater software.

【Effect of the invention〕

As described above, according to the present invention, in the push-and-run countermeasure for service reservation type group management, even on an intermediate floor where there are two types of landing calls, upward and downward, if there are no passengers in each direction, the predetermined period of time is A warning will be issued, and if there are no passengers present, the boarding call registration will be forcibly deleted.

Therefore, even on an intermediate floor where there are two types of hall calls, it is possible to clearly distinguish between the presence or absence of actual passengers and improve the efficiency of elevator response to hall calls where there are actual passengers. Passenger waiting time can be reduced.
