Abstract

PURPOSE: To make a proper guide display at time required for passengers by arranging a display means for making a prescribed guide display when a display command of a judging means is inputted. CONSTITUTION: When a door opening lengthening command 11 is energized, simultaneously when a contact point 11b and a contact point 13a are closed, a display command relay 12 is energized to close the contact point 12a. When the contact point 12a is closed, an announcing device 4A makes a guide announcement such as 'An elevator arrives at the third floor. Attention please. Dont' get off at the wrong floor.' through a loudspeaker. When two seconds pass, a time limit relay 14 operates, and the contact point 14a is closed to form a circuit of a DC power source (+) - a contact point 14a - a contact point 11c - a door closing relay 15 - a DC power source line (-) so as to start closing of a door. When a car stops in response to a car call, the door opening lengthening relay 11 is not energized, so that door closing is started when two seconds passes after completing door opening. At this time, the announcing device 4A and a display 4B are not operated.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an elevator control device, and more particularly to an improvement in a control device for controlling a display provided inside a car or in a landing.

[Conventional technology]

Generally, passengers in an elevator call a car by registering a hall call using a call button provided at the landing, and passengers who board the car register a car call by operating a call button on the destination floor. When the car responds to a hall call or a car call and stops at the corresponding floor, the door is opened to allow passengers to board and alight. When the predetermined door opening time has elapsed, the car leaves the floor in order to respond to a call from another floor after closing the door again. Here, the door opening time required for passengers to get on and off is secured as the door opening time mentioned above, but if you stop in response to a hall call on the way to your destination floor, people may get off the train thinking it is their own destination floor. Sometimes there are passengers who do this. After getting off the car, I realized my mistake and tried to get back on the original car, but...
In many cases, the door of the car is already closed and you cannot ride. Conventionally, in order to prevent the mistake of getting off the car as mentioned above, when the car arrives at the floor, a sound is heard through a speaker installed inside the car.
For example, a floor guide such as ``This is the third floor'' is broadcast to notify passengers.

[Problems to be solved by the invention]

Since the conventional elevator control device is configured as described above, floor guidance is broadcast every time a car arrives at a floor. As a result, it is extremely annoying for passengers who know exactly what floor the car has arrived at based on the car position indicator inside the car, and guidance when unnecessary for passengers is unpleasant. There was a problem that it gave. This invention was made in order to solve the above-mentioned problems, and by displaying appropriate guidance at the time when passengers need it, it is possible to avoid causing discomfort to passengers, and to make it easier for them to reach their destination. To provide an elevator control device capable of reducing the number of passengers who get off at the wrong place.

[Means to resolve the problem]

The elevator control device according to the present invention opens the door when the car stops at a floor in response to a call, and closes the door again after a predetermined door opening time and leaves the floor. An alighting passenger detection means that operates when a passenger getting off the car is detected; a car call response detection means that operates when it detects that the car has stopped in response to a car call; and a car call response detection means that operates when the car has stopped on a floor without the car call response detection means operating. a determining means for outputting a display command when the alighting passenger detecting means detects operation within a predetermined period of time after the door is opened; The system is equipped with a display means for displaying a predetermined guidance when the user is asked to do so.

[Effect]

The elevator control device according to the present invention is provided with a display means for displaying the floor at which the elevator has stopped if an alighting passenger is detected before a predetermined time elapses after the door is opened when the elevator stops in response to a call other than a car call. Because of this, it is possible to display appropriate information at the time when it is needed by passengers, thereby preventing passengers from feeling uncomfortable and reducing the number of passengers who get off at a different floor than their destination. becomes possible.

Reference numeral 4B is a display device that provides predetermined guidance using characters on a display (for example, a display device using a fluorescent display tube or liquid crystal display) installed on the side wall of the hall, and is connected in parallel to the broadcasting device 4A. There is. A display means 4 is constituted by the broadcasting device 4A and the display device 4B. In the elevator control device configured in this way,
Assume that the car is currently traveling up the third floor in order to respond to an up call on the fourth floor and a car call on the fifth floor. At this time, the front floor detection relay contact 10 is closed, so
The door closing relay 15 is energized, and accordingly, its contact 15a is opened. When contact 15a opens,
Since the door opening relay 16 is deenergized, its contact 16a
is closed. Furthermore, since the traveling relay contact 9 is open, the door opening time setting time relays 13, 14 are both deenergized, and the contacts 13a, 13b, and 14a are accordingly opened. Further, while the car is running, the fully closed detection switch 7 is open and the fully open detection switch 8 is closed, so the door opening extension command relay 11 is deenergized. As a result, the contacts 1'la to llc are opened, and the contact lid is closed. Here, since the contact 11b is opened, the display command relay 12 is deenergized, and its contacts ] and 2a are opened. Furthermore, the car call response detection contact 2Aa is closed, and the hall call response detection contact 2.8a is open. Here, when the car approaches the fourth floor, it starts decelerating and the hall call response detection contact 2Ba is closed. When the door reaches the position 75 mm in front of the seat on the fourth floor, the seat detection relay contact 10 opens, so the door closing relay 15 is deenergized and its contact 1.5a closes. As a result, the DC power line (
-) - Contact 15'a ~ Fully open detection switch 8 - Door open relay 16 - DC power line (-) A circuit is formed and the door open relay 16 is energized, and the contact 16a opens, thereby opening the door. It will start to open. On the other hand, when the car is stopped, the running relay contact 9 is closed, but since the door opening relay contact 16a is already open, the door opening time setting time relay 13.1.4 is not energized. Next, when the door starts to open, the full-close detection switch 8 is closed, and when the door is fully opened, the full-open detection switch 8 is opened, so the door open relay 16 is deenergized and its contact 16a is closed. When the contact 16a is closed, the time relay 13.14 for setting the door opening time is energized, and the time relay 13 is operated after 2 seconds, and the contacts 13a and 13b are closed. Here, it is assumed that the passenger detection device IA detects an alighting passenger and the contact 1a is closed at least once before the contacts 1.3a and 13b are closed. Then, the circuit becomes DC power line (+) - alighting passenger detection contact 1a - corner call response detection contact 2Aa - hall call response detection contact 2Ba - fully closed detection switch 7 - door open extension command relay 11 - DC power line (-) is formed, the door opening extension command relay 11 is energized, and contact 1
1a is closed. When contact 11a closes, DC power line (→-) - contact 11a - car call response detection contact 2A
a - Hall call response detection contact 2Ba - Fully closed detection switch 7
-Door opening extension command relay 11-A DC power line (-) circuit is formed to form the monthly extension command relay 11, and the door opening extension command relay 11 is self-maintained. Also, when the monthly extension command relay 11 is energized, its contact 11b
, Ilc are closed, and the contact 11d is opened. Therefore, even if the contact point 13b is closed, the door closing relay 15 is not energized, and accordingly, the door remains open. On the other hand, at the same time as the contacts 11b and 13a are closed, the display command relay 12 is energized and its contact 12a is closed. When contact] 2a closes, the broadcasting device 4A broadcasts the following information through the speaker: ``You have arrived at the third floor. Please be careful not to get off the train by mistake.'' Also,
The display device 4B displays the same guidance as that broadcasted by the broadcasting device 4A on the hall-side display. Then, when another 2 seconds pass, the time relay 14 operates and its contact 14a closes, so that the DC power line (+) - contact 14a - contact 11cm door opening relay 15 - DC power line (-) The circuit is formed and the door opening relay 15 is energized, so that door closing is started. Here, if the boarding/alighting passenger detection device IA is unable to detect an alighting passenger before the contacts 1.3a and 13b are closed, and as a result, the alighting passenger detection contact 1a continues to be in an open state. In this case, the door opening extension command relay 11 is not energized. Therefore, contact 13a. When 13b is closed, the DC power line (''-) - contact 1
3b - Contact 1id - Door closing relay 15 - DC power line (
-) is formed and the door closing relay 15 is energized. When the door closing relay 15 is energized, it will start closing the door 2 seconds after the door opening is completed. At this time, since contact 15b is open, display command relay 1.2A is not energized. Furthermore, when the car stops in response to a car call, the car call response detection contact 2Aa is opened, so the door opening extension command relay 11 is not energized, and the door is closed 2 seconds after the door is opened. Start. At this time, the broadcasting device 4A and the display device 4
B is never activated. In this way, even though the car did not stop in response to a car call, if a passenger is detected getting off the car before a predetermined time has elapsed after the door is opened, it is determined that the passenger got off at the wrong floor. In addition to displaying a guide to be careful not to get off the vehicle by mistake, the vehicle also extends the door opening time to ensure the time needed to get on the vehicle again. Therefore, the information can be displayed at a time when it is really needed by the passengers, thereby eliminating unnecessary discomfort to the passengers. Furthermore, if the passenger makes the mistake of getting off the car, the door opening time is extended, making it easier for the passenger who has noticed the mistake to board the car again. In addition, in the above embodiment, in order to detect passengers getting off the train,
Although we have described the case where a pushing device installed on the car floor is used, the method of detecting passengers getting off the car is not limited to this. It goes without saying that it is also possible to distinguish and detect passengers getting on and off the train using a device that makes decisions based on tracking. Furthermore, the content of the guidance display is not limited to that used in the above embodiments, and may be of any kind as long as it makes the passengers who have mistakenly gotten off the train aware of it. Further, the installation location of the speakers and display is not limited to the above embodiment, but may be installed in any location as long as the contents of the guidance can be sufficiently conveyed to passengers. Furthermore, in the above embodiment, when a passenger who has erroneously got off the train is detected, the door opening operation is delayed by a predetermined time (2 seconds), but it is also possible to delay the door closing until a passenger is detected reboarding. It is also easy to do. Additionally, a door-closing method is also commonly used in which a photoelectric device is installed at the entrance and exit, and the door starts closing when the elapsed time after the light beam is blocked by a passenger and the light is allowed to pass again exceeds a predetermined value (1 second). However, even when using an alighting passenger detection device using such a method, the above predetermined value may be set to 1, for example.
By extending the time from seconds to three seconds, it is easily possible to secure time for passengers who mistakenly get off the train to reboard.

【Effect of the invention】

As described above, according to the present invention, when an elevator stops at a floor in response to a car call, the door opens, and when a predetermined door opening time has elapsed, the door closes again and leaves the floor.
The alighting passenger detection means detects a passenger getting off the car, the car call response detection means detects whether the car has stopped in response to the car call, and the determination means detects whether the car has stopped in response to the car call. Although it has not stopped,
When an alighting passenger is detected before a predetermined time has elapsed after the door is opened, a display command is output and a display means is activated, thereby providing guidance in the car and at the landing in accordance with the display command. This has the excellent effect of reducing the number of passengers who mistakenly get off the train without causing discomfort to the passengers.
