[Problem to be Solved by the Invention] In the elevator control device as described above, when a general passenger operates a hall call button and then a specific passenger operates a hall call button for a specific passenger, the specific passenger does not operate the hall call button. However, the opening time of the door on the destination floor becomes the time for general passengers, making it difficult for specific passengers to get on and off.Therefore, there is a problem in that the emphasis is only on operational efficiency and the safety for specific passengers is neglected.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator control device that can improve the safety of a particular passenger during elevator operation.

[0005]

[Means for Solving the Problems] An elevator control device according to the present invention is provided with hall call buttons that are operated exclusively by general passengers and specific passengers, and after the hall call button exclusively for general passengers is operated. Even if a hall call button dedicated to a specific passenger is operated, the control is given priority to the operation by the specific passenger.

[0006]

[Function] In this invention, even if the hall call operation by a specific passenger is delayed compared to the hall call operation by a general passenger, the specific passenger's operation takes priority and the door opening time becomes longer.
To make it easier and safer for specific passengers to get on and off the hall.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sequence circuit diagram of an embodiment of the present invention. In order to simplify the following explanation, the hall call button is operated only on the first floor, and the hall call button is operated only when the elevator car is ascending.

In FIG. 1, (+) and (-) are DC power supplies, 1 is a hall ascending call button for general passengers provided in the hall on the first floor, 2 is a relay for hall ascending call button 1, and 2a is a relay 2. The normally open contact 3 is an off-delay timer relay 3a that is deenergized after a predetermined time period after being disconnected by the relay 2.
, 3b is a normally open contact of off-delay timer relay 3, 4a,
4b is a normally open contact of a car position detection relay (not shown) on the first floor that is energized when the car is on the first floor, 4c and 4d are normally closed contacts, and 5a and 5b are energized when it is decided to stop. ,
Normally open contact 5c of a stop decision relay (not shown) that then stops and continues to be energized until the door is closed again after boarding and alighting.
, 5d are normally closed contacts.

1S is a hall up call button for specific passengers provided on the first floor, 2S is a relay for the hall up call button 1S,
2Sa and 2Sb are normally open contacts of relay 2S, and 3S is an off-delay timer relay that is disconnected and deenergized after a predetermined time when a hall up call is made for a specific passenger on the first floor. 3Sa and 3Sb are normally open contacts of relay 3S, 6 is a relay that issues a hall call stop operation command for general passengers, 6a and 6b are normally open contacts of relay 6, and 7 is used to operate hall ascending call button 1 when energized. A relay 7a is a normally open contact of the relay 7, which commands a hall call stop operation for a specific passenger to extend the door open time and slow down the door closing speed compared to when the door is stopped.

Next, the operation will be explained based on the above configuration. First, the operation of registering a call using the hall call button is as follows: When the hall ascending call button 1 for general passengers installed in the hall on the first floor is operated, relay 2 is activated by the (+)-1-2-(-) circuit. The normally open contact 2a closes, and (+)-2a
The off-delay timer relay 3 is energized by the circuit -4c-3-(-), and the contacts 3a and 3b are closed. By closing the contact 3a, the (+)-3a-4c-3-(-) circuit is self-maintained and the call registration is completed.

Next, when the car arrives at the first floor in response to the above call registration, the first floor position detection relay (not shown) is energized, its normally open contact 4a is closed, and its normally closed contact 4c is closed. opens. In addition, a stop decision relay (not shown) is energized,
The normally closed contact 5a of this is closed, and the normally closed contact 5c is opened. As mentioned above, since the normally closed contacts 4c and 5c open,
The off-delay timer relay 3 is deenergized after 0.1 seconds, for example, and subsequent calls by general passengers going up the hall on the first floor cannot be registered.

Within the time (for example, 0.1 seconds) when the off-delay timer relay 3 is deenergized, (+)-3b-4
In the circuit a-5a-6-(-), the relay 6 to which a hall call stop operation command is issued by an operation by a general passenger is energized, and the contact 6a is closed, so that the relay 6 is self-maintained.

[0013]Here, if you operate the hall ascending call button 1S provided in the hall on the first floor for specific passengers, (+)-1S
-2S- Relay 2S in the (-) circuit is energized,
Normally open contacts 2Sa and 2Sb are closed, and (+)-2Sa-4
The off-delay timer relay 3S is energized by the circuit d-3S-(-), and the contacts 3Sa and 3Sb are closed. By closing the contacts 3Sa and 3Sb, the off-delay timer relay 3S and the relay 7 are self-maintained. When the car reaches the first floor, the first floor position detection relay contact 4b is closed and 4d is opened, and the contact 5b is closed and 5d is opened, so the off-ready timer relay 3S is deenergized and the relay 7 is self-holding. As a result, a hall call stop operation command for slowing down the door closing speed and the registration of a hall ascending call by a specific passenger are registered.

As described above, according to the present invention, even after the decision to stop the car is made in response to a general passenger's call,
When a specific passenger operates the hall call button 1S, (+)-
Relay 7 is energized in the 2Sb-6b-4b-5b-7-(-) circuit, and a hall call stop operation command that slows down the door closing speed is registered. Able to drive safely.

[0015] In the above embodiment, the explanation has been limited to the up call of the car in the hall on the first floor, but when there is a hall call in the same direction on any floor, the above operation that gives priority to specific passengers over general passengers. Needless to say, a configuration to which the following can be applied can be obtained.

[0016]

As described above, according to the present invention, when a general passenger and a specific passenger make a hall call in the same direction on the same floor, the specific passenger performs the operation for the general passenger's hall call. Since the structure is configured so that the hall call is given priority, it is possible to obtain an elevator control device that can improve the safety of specific passengers.
