Description

An embodiment of the present invention relates to an elevator control system and an elevator control method for temporarily restoring an elevator that has been suspended due to an earthquake.

Conventionally, elevators that have been suspended due to an earthquake are subject to brake diagnosis, hoistway diagnosis by low-speed driving, and floors as automatic restoration operation after earthquake control operation until maintenance personnel inspect and confirm safety. Door opening / closing diagnosis is performed. If there is no particular abnormality, the elevator operation is restarted as a temporary restoration state to ensure the convenience of the user until the elevator is completely restored (returning to normal operation).

For example, there is a conventional technique in which when an abnormality in opening / closing of a car door of a car during an earthquake diagnosis operation is detected, the opening / closing speed of the car door is reduced and then temporarily restored to a normal state. It is also known that the operation of the elevator is limited to a part of the entire ascending / descending stroke so that the operation can be restarted at an early stage.

Is configured to carry out. The floors that can be set include, for example, the reference floor (not limited to the 1st floor), the top floor, and the odd-numbered floors or even-numbered floors, which are the reference for moving the car 1 up and down. .. It is also possible to set a floor with a large number of users required from maintenance data and a large number of door opening / closing operations, or a specific priority floor such as an important floor that should be prioritized as the floor to be diagnosed. be.

The temporary restoration operation control unit 13 during an earthquake is connected to, for example, a notification control unit 32 that controls a landing operation device (notification unit) 21 and an in-car operation device 22 during a temporary restoration operation during an earthquake.

Each landing 31 is provided with a hall door (not shown), a landing operation device 21, a notification lamp (not shown), and the like.

The landing operation device 21 is operated by the user when using the elevator at the landing 31 on each floor, and is provided with an indicator (hall indicator), a car call button, and the like.

During the temporary restoration operation during an earthquake, for example, as shown in FIG. 1 (c), the display unit of the landing operation device 21 is displayed in order to notify the self-diagnosis result (non-stop floor) and the floor not subject to diagnosis. , The notification control unit 32 displays a guide (message) such as "The 2nd and 4th floors cannot be used" and a predetermined mark.

The in-car operation device 22 is provided in the car 1 and is operated by a user who gets in the car 1, and includes a destination floor button 23, a voice announcement device 24, a car door open / close button, and the like. There is.

During the temporary restoration operation during an earthquake, for example, as shown in FIG. 1 (b), a voice announcement of the operation device 22 in the car is made in order to notify the self-diagnosis result (non-stop floor) and the floor not subject to the diagnosis. From the device 24, the notification control unit 32 broadcasts a guidance (voice message) such as "The 2nd and 4th floors cannot be used". At the same time, the available floors (1, 3, 5) can be used by blinking (lighting) and turning off the destination floor button 23 of the in-car operation device 22 in response to a guidance such as "The 2nd and 4th floors cannot be used". The floors) and the unusable floors (2nd and 4th floors) may be notified.

Next, the operation of the elevator system 20 shown in FIG. 1 will be described.

FIG. 2 is a flowchart showing the operation of the elevator system 20 according to the present embodiment.

In the elevator system 20, for example, the seismic control operation control unit 11 constantly monitors the operations of the P wave detector 8, the low gull detector 9, and the high gull detector 10 (steps S1 and S3). , S4).

As a result of monitoring, if the P wave detector 8 is not operating (NO in step S1), normal operation is continued (step S2).

If the P-wave detector 8 is operating (YES in step S1) and the low-gull detector 9 is not operating (NO in step S3), it is judged to be a slight sway, and until the sway of the rope 3 or the like subsides. After waiting for a certain period of time, the normal operation is automatically restored (step S5).

When the P wave detector 8 operates, the low gull detector 9 operates (YES in step S3), and the high gull detector 10 operates (YES in step S4), a very large shake occurs. Therefore, the operation is suspended (step S6), and after the inspection by the maintenance staff (step S20), the normal operation is restored (step S21).

When the P-wave detector 8 is operating, the low-gal sensor 9 is operating, and the high-gal detector 10 is not operating (NO in step S4), the automatic diagnostic operation control unit 12 at the time of an earthquake determines the determination. The automatic diagnosis operation of the above is started (step S7).

That is, the brake diagnosis unit 14 confirms the presence or absence of an abnormality in the brake 5 (step S8), and when an abnormality in the brake 5 is detected (NO in step S9), the operation is stopped (step S10), and the above step S20. Processing shifts to.

When the abnormality of the brake 5 is not detected and it is determined to be normal (YES in step S9), the low-speed operation diagnosis unit 15 carries out a low-speed operation diagnosis in which the car 1 travels on the hoistway at a low speed (YES). Step S11).

If it is determined by this low-speed operation diagnosis that there is an abnormality in the hoistway, such as the rope 3 being caught in the hoistway or the unbalanced weight 2 being unrailed (NO in step S12), the operation is suspended (step S13). ), The process shifts to the above step S20.

When it is determined in the low-speed operation diagnosis that there is no abnormality in the hoistway (YES in step S12), the high-speed operation diagnosis unit 16 further performs a high-speed operation diagnosis in which the car 1 is reciprocated in the hoistway at high speed. (Step S14).

When it is determined from these diagnosis results that the car 1 can be moved up and down, the door opening / closing operation control unit 17 performs a door opening / closing diagnosis for the floor set as the target of the door abnormality diagnosis. (Step S15).

When the door abnormality diagnosis unit 18 determines that the results of all the door open / close diagnosis of the floor set as the target of the door abnormality diagnosis are normal (YES in step S16), the temporary restoration operation control unit at the time of an earthquake According to step 13, the temporary restoration operation is started for all the floors subject to the door abnormality diagnosis (step S17).

That is, when the first floor (reference floor), the third floor (odd floor), and the fifth floor (top floor) are set as the targets of the door abnormality diagnosis, for example, as shown in FIG. 3, the door abnormality diagnosis unit If no abnormality is found in the door opening / closing diagnosis on the 1st floor, the 3rd floor, and the 5th floor according to 18, the temporary restoration operation is started with the 1st floor, the 3rd floor, and the 5th floor as the stop floors (available floors).

At that time, the notification control unit 32 tells the landing operation device 21 and that the floors not set in the door opening / closing operation control unit 17, that is, the second and fourth floors that are not subject to the door abnormality diagnosis cannot be used. The user is notified via the in-car operation device 22.

In this case, the users on the 2nd and 4th floors can use the elevator system 20 at an early stage only by going up and down the stairs for the 1st floor, although there are some inconveniences.

On the other hand, when it is determined that there is an abnormality in the result of the door opening / closing diagnosis of a specific floor (NO in step S16), the floor is registered as a non-stop floor in the door abnormality floor registration unit 19 (step). S18). The floors that are not subject to the door abnormality diagnosis may be registered as non-stop floors.

Then, the temporary restoration operation by the temporary restoration operation control unit 13 at the time of an earthquake is started for the stopped floors other than the non-stop floor (step S19).

For example, when the 1st floor, the 3rd floor, and the 5th floor are set as the target of the door abnormality diagnosis, and the door abnormality diagnosis unit 18 finds an abnormality in the door opening / closing diagnosis of the 3rd floor, the 3rd floor is rejected. Temporary restoration operation will be started with the 1st and 5th floors as the stop floors.

At this time, based on the setting of the door opening / closing operation control unit 17 and the result of the door abnormality diagnosis, it is determined that the second floor, the third floor, and the fourth floor cannot be used. The user is notified via the device 22.

After that, when safety is confirmed by an inspection by maintenance personnel (step S20), normal operation is resumed with all floors on the 1st to 5th floors as stop floors (step S21).

In this way, the elevator system 20 returns to normal operation by being inspected by maintenance personnel, including the case where the operation is suspended in the brake diagnosis and the low-speed operation diagnosis.

In this embodiment, the floors on which the door opening / closing diagnosis (door abnormality diagnosis), which takes the longest time for self-diagnosis for automatic restoration, is performed are limited.

That is, in the automatic restoration operation performed after the occurrence of an earthquake, after the brake diagnosis, the low-speed operation diagnosis, and the high-speed operation diagnosis are performed, the door opening / closing diagnosis is performed only on the preset floor. As a result, the diagnosis time of the door opening / closing diagnosis, which takes the longest time in the automatic recovery operation, can be shortened. Therefore, as a result of being able to start the temporary restoration operation earlier, it is not possible to use all floors, but it is used even when compared to the case of simply putting it into hibernation regardless of the result of self-diagnosis. It will be possible to significantly suppress the loss of convenience for the person.

In particular, by further limiting the floors for which the door opening / closing diagnosis is performed in the priority diagnosis section where the diagnosis operation is performed, until the temporary restoration operation is started, compared with the case where all floors in the priority diagnosis section are performed. You can definitely save time.

In addition, since the users are notified of the floors that cannot be used and the floors that can be used, even if this floor cannot be used, it becomes clear which floor can be used, greatly improving user convenience. can.
