By operating the door opening button 7, the elevator which is closed when the elevator is stopped. The door can be reopened and the open elevator door can be immediately closed by operating the door close button 8.

As shown in FIG. 1, the door open button 7 is composed of an operation switch section 7a and a registration lamp 7b (the destination floor button 4 and the door close button 8 have the same configuration), and the operation switch section is provided. The ON signal of 7a is input to the digital input section DI of the control device 1 via the chattering prevention filter 9, and the digital input section DO of the control device 1 is connected so that a lighting signal is output to the registration lamp 7b. .

The main part of the control device 1 is, for example, 16
This is a micro controller incorporating a 32-bit or 32-bit microcomputer, a central processing unit CPU, a ROM as a program storage area, a RAM as a data storage area, and the above-mentioned digital input section DI, digital output section DO, and winding. Motor control unit MC for controlling the drive of the motor 5
U, a bus BUS that connects these parts, and the like. In addition, the digital output section DO has a registration lamp 7b.
In addition to the lighting control of, the drive control signal of the door motor 10 for opening and closing the door of the elevator car 2 is also provided.

Next, the operation of the elevator door-opening time extension device having the above structure will be described.

As shown in the time chart of FIG. 3 (a), the elevator car 2 stops in a door zone on a predetermined floor and automatically opens the door to allow passengers to get in and out of the door, and the door is opened for a fixed period of 2 to 5 seconds. The door will close when time passes. Then, in the middle of the door closing operation until the door closing is completed, or when the car 2 is stopped in the door zone even when the door closing is completed, the operation switch section of the door opening button 7 of the in-car operation panel 3 When the door opening operation PDO is performed from the digital input section 7a to the digital input section DI, the CPU instructs the digital output section DO to output a registration lamp lighting command, and digital output to drive the door motor 10 again in the door opening direction. Instruct the department DO to output the door opening command DT.

As a result, even during the door closing operation or when the door closing is completed, the door opening command is input again while the elevator car 2 is still stopped, so that the door opening operation is repeated.

When the door opening time extension operation is performed, as shown in FIG. 3 (b), the door opening button 7 is operated twice or more continuously within a fixed time, for example, within 2 seconds.
The operation signal is input from the door opening operation switch unit 7a to the digital input unit DI, and the CPU determines that the door opening time extension command is input from the operation signal, and the digital output unit DO receives the door opening time extension command, for example, The extension command is given for 3 minutes, the digital output unit DO outputs a lighting signal to the registration lamp 7b to turn on the registration lamp 7b, and at the same time the door motor 10 is driven to extend the door opening time, for example, 3 minutes. Keep open. To extend the door opening time, set the door timer in RAM to 3 minutes,
This is accomplished by programming the door to open for a 3-minute countdown.

When the door opening time has been extended in this way and the user has finished using the door and wishes to quickly close the door during the door opening extension time, the door opening button 7 is pressed twice again. As a result, this signal is input to the digital input unit DI, and the CPU determines that the door open continuous operation signal has been input again during the door open time extension operation, and the digital output unit performs the door close operation. Instructing the DO, the digital output section DO outputs a drive signal for rotating the door motor 10 in the direction of closing the door. Then, together with the output of the door closing command, a turn-off command is also simultaneously output to the registration lamp 7b,
Notify that the extension of the door opening time has ended. This door open extension reset resets the value of the door timer in RAM to 0.
It can be realized by clearing.

The above operation will be further described with reference to the flow chart of FIG. 4. The operation for extending the door opening time is realized by a program stored in the ROM in the control device 1, and is as follows. First, RS is a repeat start point and indicates that this program is executed in each cycle. Therefore, first, it is checked whether or not the door opening button 7 is pressed (STEP 1), and it is checked whether or not the door opening is being extended (STEP 2), which is normal, and the door opening output is about 5 seconds if it is the first operation. Output (STEP3), and if it is the second time, set a timer for 3 minutes to extend the door opening time (STEP4), turn on the door opening registration button 7b (STEP5), and output the door opening output DT. The door motor 10 is operated to open the door (STEP
6).

If the door opening time is being extended in STEP 2 above, the door opening extension is continued by the first operation input, but if the operation is the second operation, the door timer is cleared to 0 to end the door opening time extending operation. (STEP 7), the door open registration lamp 7b is turned off (STEP 8). Then, the door opening command is stopped and the door closing operation is performed (STEP 9).

As described above, in this embodiment, if the door opening operation is extended twice or more within a fixed time, for example, 2 seconds, it is determined that the door opening time extension command is given, and the door opening time is set in advance. By extending the set time, for example, 3 minutes, the door opening time extension operation can be performed without separately providing a button for door opening time extension operation on the operation panel as in the conventional case.

In the above embodiment, the door opening time extending operation is interrupted when the door opening button is continuously operated again during the door opening time extending operation, but this function is convenient. However, if it is not necessary, it may not be provided.
Further, during the door-opening time extension operation, the door-opening registration lamp is turned on to notify that the door-opening time is being extended. However, this function may be omitted if not particularly required.

The chattering prevention filter 9 is for preventing misreading when chattering occurs in the switch when the door opening operation switch 7a is continuously pressed.
It can be configured with a filter circuit of about 100 msec. The chattering prevention function may ignore a signal having a pulse length of 50 msec or less on the CPU side to prevent misreading of the signal due to chattering or noise. Furthermore, this chattering prevention function can be provided as needed, and need not be provided if not required.
