Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling the suspension of operation of an elevator.

[0002]

2. Description of the Related Art FIG. 5 is a diagram showing steps of a conventional method for controlling the suspension of operation of an elevator. Step 1 is a step of inputting a command to stop the operation of the elevator during the stop operation. Step 2 is a step of inputting a command to suspend the operation of the elevator due to the disaster operation when a disaster such as an earthquake or a fire occurs. Step 3 is a step of inputting a command to stop the operation due to the operation at the time of failure when an elevator failure occurs. Reference numeral 4 is an operation suspension process that receives a suspension command 1, a disaster command 2 or a failure command 3 and issues a command to stop the elevator at a designated floor / nearest floor or an emergency escape floor. Reference numeral 5 is a car stop step for stopping the elevator at the floor designated by the operation stop step 4. Reference numeral 6 is a car interior lighting extinguishing step of turning off the light inside the car after stopping in the car stopping step 5, and 7 is a door closing control step of closing the car door.

In the conventional method of stopping the operation of the elevator thus configured, the operation is stopped, the operation is promptly stopped and the passengers are evacuated from the occurrence of an earthquake or fire, or the elevator is out of order. In order to evacuate passengers safely, the elevator car is stopped at the designated floor, the nearest floor or the emergency evacuation floor, and the passengers are encouraged to exit the car promptly.
The lights in the car are darkened, and the normally bright landing is used to guide the passengers to move to the landing by utilizing the difference in brightness. By darkening the inside of the car, passengers at the landing are prevented from boarding, and the door of the car is closed to suspend the elevator.

Here, the designated floor is a floor which is predetermined as a floor to be stopped when it is stopped, and the nearest floor is the floor which can be stopped nearest to the earliest when the elevator issues a stop command during traveling. The emergency evacuation floor, which is not used in regular operation, is provided to evacuate passengers in the car when something goes wrong. The equipment at the landing or the room on the landing side is usually simple and often turned off even if there is lighting equipment.

However, it is not possible for the elevator side to know whether or not the platform on the resting floor, the nearest floor, or the emergency escape floor is in a bright state, and when it is particularly dark, the lights in the car are turned off or the passengers get off. Then closing the door of the car will lock the passengers in the darkness. In this case, it is dangerous for passengers and may cause psychological panic. Therefore, the following techniques have been disclosed to deal with this. That is, in the actual Kaihei 1-75077, the car interior lighting is turned on only for a predetermined time after the door is closed. JP-A-4-327
480 discloses that the lighting control device on the building side turns on the lights required to escape to another floor.

[0006]

As described above, in the former case, when the door is closed, the hall becomes dark, and the passengers who got off due to the bright inside of the car are left behind in the dark hall side. Closing it gives a great psychological anxiety. In the latter case, the lighting control of the landing is left to the lighting control device on the building side.
The elevator control shuts down the lights and closes the door without knowing the landing conditions. As a result, the passengers are overlooked by the elevators they have been on until now, and psychologically anxious. For this reason, it is not necessarily implemented in small and medium-sized buildings, where the facility burden on the building side increases.

The present invention has been made to solve the above problems, and when the car stops at an unexpected floor of a passenger due to an elevator stop command, the passenger can be safely evacuated safely. The present invention provides an elevator control method capable of controlling the elevator.

[0008]

According to the elevator operation control method of the present invention, the elevator is stopped based on an operation stop command, the brightness of the landing on the stop floor is measured, and if necessary, It prevents the lighting in the car from being dim and closing the door. If the car interior lights are turned off after the car stops but it is determined that the brightness of the landing is not at the prescribed brightness, the car interior lights are turned off again by the command to turn off the lights, and the door is closed by the door closing control prevention command. Leave it open. The brightness of the landing will be measured with an illuminometer attached to the car. Also, the brightness of the landing is determined by the turning-on state of the lighting switch of the lighting of the landing.

Further, when it is determined that the brightness of the landing has become sufficiently bright, the instruction to prevent the lights from turning off in the car and the instruction to stop the door closing control are canceled. Furthermore, at this time, after canceling the lighting off prevention command and turning off the lighting,
Cancel the door closing control blocking command and close the door. In addition, the lights are often turned off on the emergency escape floors or service suspension floors that are not normally used, and since we stopped at these floors, we estimate that the landing on this floor is dark and prevent the lights from turning off, Prevents door closing control. In a darker platform, due to artificial operations such as turning on lights and opening doors leading to bright rooms or corridors,
Cancel the prevention of turning off the lights and the prevention of door closing control.

In addition, when the hall is dark and a command to block the turning off of the light is issued or a command to block the door closing control is issued, a warning message is broadcast or displayed so that the passengers can get down while paying attention to their feet. Further, when the boarding place becomes bright, the car interior lights are turned off and the door is closed, so that a warning message is broadcast or displayed to the passenger. Further, even if the car stops on a dark floor of the landing as described above, when there are no passengers in the car, the lighting off prevention command or the door closing control prevention command is not output.

[0011]

The operation control method of the elevator according to the present invention is as follows.
By checking the brightness of the hall and turning off the lights when the brightness is not the predetermined brightness, the passenger can get off at the hall using the brightness of the light in the car. Also, when the light inside the car is turned off and the brightness of the landing is checked and it is determined that the brightness is not the predetermined brightness, the light inside the car is turned on again and the passengers use the brightness of the light inside the car to reach the landing. You can get off. Further, by using the illuminometer provided in the car to measure the illuminance at the landing, it is not necessary to provide an illuminometer at each landing, and only one illuminometer in the car may be provided. Further, as a method of determining the brightness of the hall, it can be estimated that it is bright when the illumination switch of the hall is turned on and dark when the illumination switch of the hall is turned off.

Further, when the illumination of the hall changes from a dark state to a bright state, it is no longer necessary to continue to turn on the in-car illumination, and the illumination turn-off prevention command is canceled. Further, there is a possibility that passengers may remain in the car, and the car door is closed after the lights inside the car are turned off and the passengers get off. In addition, when the floor that was stopped due to suspension is expected to be turned off in advance, such as an emergency escape floor or a service suspension floor, the light inside the car is prevented from turning off and lighting continues. Therefore, it can be realized without newly installing an illuminance meter.

Further, by the passenger getting off some operation, for example, by opening a door leading to another area, it is no longer necessary to keep lighting the car illuminating anymore, and the illumination turn-off prevention command is canceled. Also, when you stop on a floor with dark lighting at the platform, it is dangerous because your feet are dark and you may trip over.
Broadcast and display warning texts so that passengers can get down while paying attention to their feet.

Furthermore, even when the lights inside the car are turned off or the doors of the car are closed after the lights of the landing have become bright, the warning message is broadcast or displayed to that effect in the car or at the landing. Alert the passengers who got off to. Further, even when the passenger is not in the car even when the car is stopped and stopped in the dark hall, it is not necessary to keep lighting the car in the car, and the light-off prevention command or the door closing control prevention command is not output.

In each step of 03, if there is an operation stop instruction / disaster operation instruction or failure operation instruction, the process proceeds to step S201, and it is determined whether the car is traveling. If the car is running at this time, the car is stopped in step S202, and if stopped, the process proceeds to step S301. And the illuminance meter 4 installed at the landing
Based on the illuminance information measured in step 7, it is determined in step S301 whether or not the landing illuminance is bright, but if it is determined that it is dark, the process proceeds to step S305, and in steps S305 and S306, the light is turned off. Since the command and the door closing control blocking command are output and the lights are kept on and the doors are kept open, the landing can be kept bright by being illuminated by the lights of the car.

Next, in step S307, because the landing side is dark, the warning message A such as "please get off your feet carefully" is broadcast or displayed to alert the passengers getting off. be able to. Further, if it is determined in S301 that the illuminance of the landing is bright, the process proceeds to S401, in which no illumination turn-off prevention command is issued, so the car interior light is extinguished in the car interior illumination extinguishing step 6, and the operation is suspended in S402. Therefore, by broadcasting or displaying a caution message B such as “Please get off promptly”, it is possible to call attention to the passengers remaining in the car.

Further, since the door closing control prevention command is not issued in S501, the door of the car is started to be closed in the door closing control process 7, and the caution message C such as "Please note that the door will be closed" in S502. By broadcasting or displaying, it is possible to call attention to the person in the car or at the landing. When the landing that was initially dark becomes bright, in step S301, the process first proceeds to step S305 and continues to turn on the illumination and continues to open the door. Alternatively, the illumination can be turned off and the door can be closed by canceling the door closing control blocking command.

Example 2. In addition, in the above-mentioned Example 1, based on the information of the illuminance measured by the illuminance meter installed at the landing,
Although it is determined in step S301 whether the illuminance at the landing is bright, the same effect can be obtained by making a determination based on the illuminance information measured by the illuminance meter 39 installed in the car and measuring the illuminance at the landing. By installing only one car, it is not necessary to have multiple illuminance meters at each landing.

At the beginning, the hall is also illuminated by the illumination in the car, and it is judged as bright as a result of measurement by the illuminometer S40.
If it is determined that the measurement value of the illuminometer is dark after the lighting in the car is turned off, the one that has proceeded to step 1 is S305.
By going to the step, the lighting off prevention command and the door closing control prevention command are output, and the light is turned on again and the door remains open again, so it is possible to maintain the bright state again by being illuminated by the lighting of the landing cage. it can.

Example 3. In addition, in the above-mentioned Example 1 or Example 2, based on the information of the illuminance measured by the illuminometer,
Although it is determined in step S301 whether or not the illuminance of the hall is bright, this switch is turned on based on the signal from the hall lighting switch 46 on the corresponding floor of the hall or the management room of the building (not shown). For example, it can be considered that the illuminance of the landing is bright in the step of S302, that is, if it is not turned on, the process proceeds to S305, and the lighting in the car and the opening of the car door are continued.
Go to 1 and turn off the lights and close the door.

Further, similarly to the first embodiment, the switch for lighting the hall of the relevant floor is not turned on at first and the lighting is continued to be turned on and the door is opened. At this time, in S308, the light is turned off and the door is closed. The initial value is set to the timer counter for taking the time limit of. This set value is the time that is the time limit divided by the calculation cycle of this program.

When the hall lighting switch is turned on, the car light is first turned off and the timer counter is checked in step S403. If it is not zero, the timer counter value is counted down by "1" in step S404. It is performed every time, and when it finally becomes zero, the routine proceeds from S403 to S501, and the door is closed.
In other words, the door does not close immediately after the lights are turned off, but the time for getting off the car should be secured if there are passengers left in the car.

In some cases, a similar time period is secured between turning off the light and closing the door in the original resting process, but the time relay starts to operate when the light is turned off or the counter on the program counts down. The light-off prevention command is not linked, and for example, in the case where the light-off prevention command is issued after the light-off is delayed, when the light-off prevention command is cancelled, the time period has already been completed, and the light-off and door closing Cannot secure a time limit between.

Example 4. In addition, the above-mentioned Example 1 and Example 2
Alternatively, in the third embodiment, the brightness of the landing is measured directly by the illuminometer or the like or indirectly by the lighting switch or the like to perform the pause control, but it is predicted in advance that the lighting is turned off here. Shows the case of stopping at the landing due to suspension. In other words, when it is expected in advance that the landing lights will be turned off, such as an emergency escape floor or a service suspension floor,
It does not turn off the lights and does not close the door. That is, S30
In step 3, when the hall lighting is paused on a floor where it is expected that the lights will be turned off in advance, the process proceeds to step S305 to issue a lighting off prevention command.

Next, even if the passenger gets off even in a dark hall, the brightness of the hall can be controlled by opening the door leading to the area where other lights are turned on even if the passenger does not perform any operation, for example, turning on the lighting switch. Since it is possible to secure the light, it is possible to turn off the light in the car, so that it is possible to cancel the light turn-off prevention command or the door closing control prevention command. For example, when the evacuation door 44 for opening from the emergency escape floor is opened, the detection switch 49 operates, and by inputting this signal, in S304, it is determined that an artificial operation is performed, the process proceeds to S401, and the light is turned off. The command is canceled and the light can be turned off.

Next, when the lighting of the hall is dark at the time of the above-mentioned rest, it is to guide the passengers in the cage to the hall safely by trying to maintain the brightness of the hall by the lighting in the cage. It is not necessary to prevent the lights in the car from turning off if there are no passengers inside. Therefore, for example, when the passenger sensor 61 provided on the car floor in the car and operated by stepping on by the passenger does not detect the passenger in the car, S6
At step 01, immediately proceed to the exit of S107,
Do not go through the step of issuing the 305 lighting off prevention command,
The elevator is stopped for a rest, and then the light is turned off and the door is closed as in the conventional case.

[0036]

Since the present invention is constructed as described above, it has the following effects.

When the brightness of the landing on the stop floor, which is stopped based on the elevator stop command, is dark, it is possible to guide the passengers inside the car to the landing safely by turning off the light of the car to prevent the operation of closing the door. You can

Further, when the light inside the car is turned off based on the elevator stop command and the brightness of the landing on the stop floor is dark, the car light is turned off to prevent the operation of closing the door and the door is turned on again. By opening, passengers in the car can be safely guided to the landing.

Furthermore, one illuminance meter provided in the car is used to measure the brightness of the hall, and the brightness of the hall can be measured without providing a plurality of illuminance meters on each floor. it can.

Further, the brightness of the landing is judged by whether or not the lighting switch of the landing on the floor is turned on, and a complicated measuring instrument such as an illuminance meter is added only for this measurement. Instead of installing it, the existing equipment is used.

Further, when the elevator stops according to the stop command, it is determined that the brightness of the hall is dark, and after the car lights are kept on, the car lights are turned off when the brightness of the hall becomes bright. It guides passengers in the car to the landing.

In the same manner as above, when the dark hall becomes bright, the lights in the car are turned off, and after a lapse of time for the passengers in the car to exit, the doors are closed to allow the passengers to move. When you try to get out, you can safely exit the car without crossing the closed door.

Furthermore, when the floor where the car is stopped is an emergency stop floor or a floor where the lights at the platform are expected to be turned off in advance, such as an emergency stop floor or a service stop floor, by continuing to turn on the car lights and open the doors, Stopping at these floors can be recognized in the control of the elevator without additional work such as installation of an illuminance meter or wiring connection to a lighting switch, so that the present invention can be easily realized.

When a door such as an emergency escape floor is turned off and a door leading to another adjacent room or a corridor is opened, the light in the car is turned off and the door is closed. However, in an emergency, passengers usually cannot afford to turn on the lights of the landing, and the conditions for evacuation on the landing side are based on artificial operations such as opening doors, which is a natural activity for passengers. As a tidy one, the lights of the car are turned off and the door is closed.

Further, when the landing is dark and the lighting of the car is continued without being turned off, the passengers descending from the car proceed toward the dark landing, and their feet are unstable.
Also, as an elevator, it is necessary to drop passengers in order to stop, and it is possible to call attention by issuing a caution message such as "please get off your feet carefully".

Also, after stopping on the rest floor, when the lights in the car were turned on due to the darkness of the landing, when the lights were turned off this time and the door was closed, to those who were in the car or around the door of the car, It is possible to call attention by issuing a cautionary message such as, for example, "Because it will be paused, please leave the door upon exiting."

Furthermore, when there are no passengers in the car,
Since it is not necessary to keep the lights in the car on, the lights are not kept on even when the landing is dark.
