Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for controlling the opening and closing of elevator doors.

In the receiving elevator, there are times when it is desired to temporarily occupy a stopped car for loading and unloading cargo. In this case, by pressing the door opening time extension button (hereinafter simply referred to as the door opening extension button), the door can be left open for, for example, three minutes. If you finish your work within this time and press the door close button, the door will close and you will be able to respond to calls from other floors.

However, if the car occupant forgets to press the door close button after completing work, the door will not begin to close until the three minutes mentioned above have elapsed, making it impossible to call the car from another floor.
Even if a landing call is registered on another floor before pressing the door opening extension button, it is unknown and there is a risk of being occupied for a long time. Furthermore, even for the person temporarily occupying the car, since he or she does not know the elapsed time or the remaining time, it is troublesome to rely on intuition and press the door opening extension button many times.

This invention is intended to improve the above-mentioned problem, and when the door opening extension button is operated, the door closing button is operated after the door is used.
To provide a door opening/closing control device for an elevator that can prevent forgetting to operate a door closing button and delaying work by notifying you when work is promoted.

49a), -(49b) An automatic notification device which emits an audio signal corresponding to K, and (51) a speaker installed in the car and connected to the automatic notification device 14.

Next, the operation of this embodiment will be explained.0 Now, suppose that the car is on the 5th floor and no landing call has been registered, and the door opening extension button (1) is pressed.
The door open time extension time relay (2) operates and the contact (2a)
- (2c) will close 0 When you release the door opening extension button (1), the contacts (2a) - (2c) will continue to close for 3 minutes. When pressed, the door opening extension button relay (3) is also energized, but as soon as the door opening extension button (1) is released, it is deenergized.

By closing contact (2a), (→-r2a)-(9b)
-QO-(→The circuit energizes the door opening command relay αQ, the door begins to open, and once it is fully opened, it remains in that state.

On the other hand, if the flashing time relays (b) and (2) are both in the reset state, the contact (lla) will open and the contact J1
2a) is closed. Therefore, when the power is turned on, the time relay α° C. is energized and the contact (lla) is closed.

Now, the time relay (2) is also energized and the contact (12a)
will open, so after 1 second the timed relay (l◇ will return,
The contact (lla) opens and returns to the initial state. After that, repeat the same operation to block the light. That is, the time-limited relay α repeatedly operates for 1 second and returns for 1 second, and the contact (11b) closes for 1 second and opens for 1 second, thereby blocking light. At this time, contact (2
b) is closed, so the door close button light (to) is connected to the contact point (
111)), it repeatedly flashes on and off for 1 second and off for 1 second to call attention to the operation of the door close button (7) after use.

Now, when the contact point (3a) is opened by deenergizing the door opening extension button/relay (3) described above, the contents of the counter (to) are reset to zero. On the other hand, contact (9d) and contact r2
c) Since jd is opened and closed, the output of the AND gate (to) becomes a pulse that is synchronized with the opening and closing of the contact (llc). Therefore, the counter (to) counts the number of times the contact (llo) closes. Since the 0 contact (llc) closes once every 2 seconds, the output of the counter (g) is the number of times the contact (llo) closes. Button (1
), and is expressed as 2N (where N is the number of times the contact (llc) is closed).
subtracts the output of the counter (to) from the set value 90. The set value 9o is equivalent to 3 minutes (180 seconds) K (2 seconds x 90 =
180 seconds), the output of subtractor 01 represents the remaining time until the set time of 3 minutes expires.
When a) is open, the oscillator circuit generates one pulse (20a) every 30 seconds. Every time this pulse (20tL) is input to the output control circuit (product), an elapsed time signal (zla) corresponding to the output of one counter (total) and a subtractor a
The automatic notification device control generates the remaining time signal (21b) corresponding to the output of e (21b).
), and the speaker 51) broadcasts, for example, ``30 seconds have passed. There are 2 minutes and 30 seconds left, so please press the door close button when you have finished using it.'' 3
If a pulse (20a) is input after 0 seconds, it will say "1 minute has passed. There are 2 minutes left.

When the time limit relay (2) for extending the opening time of the three doors has expired,
Contacts (2a) to (2c) are open. By opening contact (2a), door open command relay αQ is deenergized, and contact M2b>
When the button is opened, the door close button light (to) goes out. Also,
By opening the contact (2C), the output of the AND gate α becomes rLJ, so the time calculation device αη stops calculation.

In addition, one door close button (7) can be pressed while the time calculation device α force is operating.
When is pressed, the door close button relay (8) is energized and the contact (8a) is closed. Now, (→−(8a) −(
6c) - (9) - (→ circuit, door close command relay (9
) is energized and self-retains by closing the contact (9a). Then, the door begins to close due to the activation of the door close command relay (9).

i9, contacts (9b) to (9d) are opening contacts (9b)
), the door open command relay αQ is deenergized, and when the contact (9c) is opened, the door close button light (to) is extinguished. Further, by opening the contact point (9d), the time calculation device (b) stops calculation.

On the other hand, the traffic status calculation device (2) always calculates the number of registered hall calls and the longest registration time among those calls.

For example, when an up call on the first floor is registered, the up call registration relay contact (14a) is closed.The time when the 0 contact (14a) is closed is the call registration time.
When the counter (2) is closed, the counter (2) becomes capable of counting, and the AND
The output of the gate (to) is a pulse that is synchronized with the opening and closing of the contact (IXa). Therefore, the counter (to) is output from the contact (11).
11) Count the number of times of closing. As mentioned above, the number of times K is counted represents the elapsed time, so the output of the counter becomes the registration time of the up call on the first floor. Now, if the registration time for the up call on the 1st floor is 20 seconds and the registration time for the up call on the 6th floor is 10 seconds, then the counter (To).

The outputs of (2) correspond to 20 seconds and 10 seconds, respectively. The maximum value selection circuit O'h selects the maximum value among the inputs and provides an output corresponding to 20 seconds to the output control circuit -. This value then increases over time. On the other hand, the call number counting base is the upward call registration relay contact (la) on the 1st and 6th floors,
(14f) is counted, that is, 2, and if a pulse (20a) is input after 5 seconds have elapsed since the output control circuit (IaK is applied), the output of the maximum value selection circuit (b) is 25 Since it is in seconds, a call registration time signal (49a) corresponding to this and a call registration number signal (49b) corresponding to two are emitted. Automatic notification device ff11
is belief 1 above! (49a), (49su) will be emitted, and the speaker (51) will say, for example, "People on other floors have been waiting for 25 seconds. You can call us on the 1st and 6th floors." , which will be broadcast in conjunction with the above-mentioned broadcast.Then 30
When the pulse (20a) is input after 9 seconds, if the call situation continues as it is, the 25 seconds mentioned above will be broadcast as 55 seconds.

It goes without saying that the content of the broadcast is not limited to the embodiment, and when the door open button (5) is pressed, the door open button relay (6) is energized and the contact (6a) is closed. Now, the door opening command relay is energized by the circuit (→-(6a)-(9b)-Ql)-), the door opens, and when the door opening is completed, the door begins to close again. Details regarding these operations will be omitted.

In this way, the elapsed time after the door opening extension button (1) is operated, the remaining time, the number of hall call registrations, and the longest hall call registration time are broadcasted, and the door closing button light (to) is broadcast.
The door close button (7) fr should be blinking to draw attention to its operation. Therefore, the person who operated the door extension button (1) would have to press the door close button (7) after it has been used. You won't forget to press the button, and since you can see the status of other waiting customers, you won't be bothering other waiting customers by doing things in a leisurely manner. More KF! J! Since you can see the elapsed time and remaining time, you don't have to worry about the remaining time and press the door extension button (1) over and over again, and your work progresses in a planned manner, eliminating wasted time.

As explained above, in this invention, when the door opening time extension button that keeps the elevator door open for a certain period of time is operated,
By instructing the driver to operate the door close button after use, it is possible to eliminate the inconvenience to other waiting customers due to forgetting to operate the door close button.Also, the door opening time extension button can be operated. Then, the elapsed time, traffic conditions, etc. are calculated and notified, so it is possible to encourage the workers to accelerate the work. Mouth that can be prevented from operating buttons
