Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device.

[0002]

2. Description of the Related Art With the aging of society and the growing interest in welfare, the number of households equipped with elevators is increasing, and especially for buildings with three or more floors, elevators are needed as much as necessary items. Is starting to appear.

By the way, with respect to the elevator, it has become a device that can be easily used by anyone due to the increase in the number of buildings and the spread of condominiums in recent years. Even if the elevator is installed in a private house, there is no particular problem in handling. Although it is unthinkable, there are times when people who do not normally use the elevator, such as the elderly, infants and people with disabilities, use it alone.
It is necessary to pay particular attention to safety.

In consideration of such safety requirements, the following measures are currently taken for elevators for private residences. One is to follow the current usage of high-performance elevators for buildings, and to be able to use it in almost the same way as normal operation. The other is special consideration for private housing. It is a thing.
And in particular, since the door opening and closing method is one of the most important mechanisms in the elevator in terms of safety,
Various methods have been adopted.

In such an elevator, an elevator control device for fully automatically opening and closing the door performs the door opening / closing operation as follows.

When the call button is pushed from the hall, the elevator arrives, the door automatically starts to open upon arrival, and when the door is fully opened, it is held for a certain period of time. The user who called in this state will get into the elevator car,
The door will start to close after a certain period of time after full opening, and the elevator will automatically start toward the destination floor of the user when completely closed. In addition, by operating the door closing button in the car, the opened door can be closed immediately after the full opening without the lapse of a certain time.

Further, there is provided a mechanism for preventing a person from being caught in the door when the door is closed. When this mechanism is operated, the door which has been closed can be restarted and the danger of being caught can be avoided. it can. Further, a door opening button is provided in the car so that the door which has been closed can be reopened by the operation of the user, and the door can be kept open by continuing to push.

However, in such an elevator control apparatus of the automatic door opening / closing type, even if the door opening button and the door reopening mechanism are provided, the fingers are caught in the door pocket at the door opening operation and the door closing operation is performed. Sometimes it is not possible to avoid impact when hitting the human body, and it is still desired to improve safety for the elderly, infants, people with disabilities, etc., and it can not be said that it is the optimum method especially for elevators for private houses There was a problem.

On the other hand, an electric type in which a door is opened and closed by a user's operation is also adopted. This has a door opening operation button and a door closing operation button in the hall and the car, and when the door can be opened and closed, the door can be opened and closed by operating these operation buttons, and the operation of the operation button is stopped. And the movement of the door is stopped on the spot. In the case of this electric type, in the unlikely event that fingers etc. are likely to be caught in the door pocket, the user can avoid the danger simply by releasing the operation button, and after confirming safety, again, The door can be opened and closed by operating the operation button.

This electric elevator control device has a feature of high safety because it is directly operated by the user, but on the other hand, there is a trouble that the operation button must be continuously pressed to open and close the door. Also, if you forget to close the door, you will not be able to answer calls from other floors, so you must always close the door when you get off the elevator, which is a problem in terms of usability.

[0011]

As described above, in the conventional elevator control apparatus in which the door is opened and closed fully automatically, even if the door opening button and the door reopening mechanism are provided, It is unavoidable to pinch your fingers in the door pocket during operation, or to avoid the impact of hitting the human body when closing the door, and for the elderly, infants, people with disabilities, etc.
There is a demand for improved safety, and there is a problem that the elevator is not the most suitable method, especially for elevators for private houses.

In addition, the electric elevator control device that opens and closes the door with the operation button has a high safety feature because it is directly operated by the user, but on the other hand, the operation button must be continuously pressed to open and close the door. There is a lot of trouble, and if you forget to close the door, you will not be able to respond to calls from other floors.Therefore, you must always close the door when you get off the elevator, which makes it inconvenient. was there.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide an elevator control device suitable for personal residences, which does not require complicated operation and is highly safe.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a functional block diagram of an embodiment of the present invention. The elevator control device of this embodiment has call registration switches 1a, 1 installed in a car and a hall.
b, ..., A call input circuit 2 for inputting the call registration signals of these call registration switches 1a, 1b, ..., An operation control circuit for controlling the operation of the elevator based on the call registration signal input to the call input circuit 2. 3, a door opening / closing control circuit 4 for opening / closing driving of an elevator door by a command from the operation control circuit 3, a door state detection switch 5 for detecting a state of an elevator door, and a command based on the door opening / closing control circuit 4 A door drive device 6 for opening and closing the door is provided.

Further, door opening / closing operation stop switches 7a, 7 are provided in the car and in the hall near the call registration switches 1a, 1b ,.
b, ..., These door opening / closing operation stop switches 7a, 7
a stop signal input circuit 8 for inputting stop signals b, ... Based on a door open / close stop signal input to the stop signal input circuit 8, an operation state signal from the operation control circuit 3, and a signal from the door state detection switch 5. A door opening / closing stop control circuit 9 for outputting a signal for stopping the door opening / closing operation.

Next, the operation of the elevator control device having the above configuration will be described.

Normally, by operating the call registration switches 1a, 1b, ... Installed in the car or in the hall, the respective input signals are input to the call input circuit 2,
It is sent to the operation control circuit 3. The operation control circuit 3 operates as necessary based on the position of the elevator car or the door state input from the door state detection switch 5. When the elevator arrives at a predetermined floor, a door open command signal is sent to the door opening / closing control circuit 4, and the door drive device 6 opens the door. A door closing command signal is sent to the door opening / closing control circuit 4, and the door driving device 6 causes the door to close until the door is fully closed.

When the door is in the fully closed state, the door state detection switch 5 detects the fully closed state of the door and sends the signal to the operation control circuit 3, and the operation control circuit 3 confirms the fully closed state of the door. Then drive the car to the required floor.

However, in such a normal elevator operation control, there is a possibility that a finger or other portion may be caught or pulled in the door gap during the door opening / closing operation. (1) When such a situation is likely to occur, the user opens / closes the door opening / closing operation stop switches 7a, 7 installed in the car or in the hall.
By pressing any one of b, ..., the door being opened / closed can be stopped at that position in an emergency, and such a danger can be avoided.

Explaining the operation in this case, if the door opening / closing operation stop switches 7a, 7b, ... Are operated,
A door opening / closing operation stop signal is input to the input circuit 8 and is input to the door opening / closing stop control circuit 9 from this input circuit 8.
At, the door state is input from the door state detection switch 5, and if it is confirmed that the door opening / closing operation is being performed, the door opening / closing operation is stopped urgently. If a stop signal is continuously input from the door opening / closing operation stop switches 7a, 7b, ... If the door opening / closing operation is stopped during that time and there is no signal from the door opening / closing operation stop switches 7a, 7b ,. After a certain period of time, the door driving operation up to that point is restarted and the normal operation is resumed.

Next, the procedure of the door opening / closing stop operation by the door opening / closing stop control circuit 9 will be described with reference to the flowchart of FIG.

When the door opening / closing operation is not stopped and is in normal operation (step S1), it is first checked whether or not the door opening / closing operation is being performed (step S2). Here, if the opening / closing operation is not performed, the process is ended as it is, and if the opening / closing operation is being performed, it is checked whether or not a signal is input to the door opening / closing operation stop switches 7a, 7b, ... (Step S3).

At step S3, the stop switch 7a,
If there is no stop signal input from 7b, ... However, if there is an input, the door state detection switch 5
The door state is checked based on the signal from the door (step S4). If it is not fully opened or fully closed, that is, if the door is in the intermediate state of opening or closing, the open / close position of the door. And the opening / closing direction are stored in a storage unit (not shown) incorporated in the door opening / closing stop control circuit 9 (step S5).

Next, a process during the door opening / closing operation is stopped (step S6), and a door operation stop signal is output to the door opening / closing control circuit 4. And a door operation stop timer (this is also incorporated in the door opening / closing stop control circuit 9)
To a predetermined time, and the operation ends (step S
7).

In this way, if any dangerous state is predicted during the opening / closing operation of the elevator door, the stop switch 7a,
By pressing 7b, ..., the opening / closing operation of the door can be urgently stopped, and the danger can be avoided.

Next, a case where the door opening / closing stop process is performed again will be described. If the door opening / closing operation is stopped, the determination in step S1 becomes YES, and the door opening / closing operation stop switches 7a, 7b, ...
Is pressed and the door open / close operation stop signal is input, and if the stop signal from the stop switches 7a, 7b, ... Is input, the operation branches to the side and the door open / close operation state is stored again. Then, the door opening / closing operation stop processing is executed, and the timer is set (steps S4 to S7). That is, as long as the door opening / closing operation stop switches 7a, 7b, ... Are operated, the timer does not change and the door opening / closing operation emergency stop state is continued.

However, if the stop signal is not input from the door opening / closing operation stop switches 7a, 7b, ..., In step S8, the process branches off to the end, and the door opening / closing operation stop processing is continued (step S9) while the timer state is maintained. Is checked (step S10). This timer expires after a predetermined time elapses, and if the timer has not expired in the check routine, the process ends as it is, and the door opening / closing operation stop process continues.

Then, the same processing is repeated until the timer time elapses, and when the timer has passed the set time and the end thereof is detected in this check routine (step S10), it is stored in the door opening / closing operation state storage section. The door open / close operation state that has been performed is reset in the operation control circuit 3 (step S11), and the door open / close operation stop is released (step S).
12). As a result, the door returns to the original state, the door closing operation is restarted if the door closing operation is in progress, the door opening operation is restarted if the door opening operation is in progress, and the normal operation is resumed.

In this way, when a person is likely to be caught in the door that is closing or the finger jamming is likely to occur when opening and closing the door on the stop floor, the stop switches 7a, 7b, ... It is possible to urgently stop the opening / closing operation of the door at the operating position by operating, and avoid danger to the user.

[0035]

As described above, according to the present invention, the automatic door opening / closing is performed, and if a danger occurs during the door opening / closing operation, the door is temporarily stopped at that position and the danger is avoided. Since the door opening / closing operation can be restarted from the stop position, it is possible to secure the convenience of the fully automatic type and the safety close to the electric type when opening / closing the door.
