Description

  The present invention relates to an elevator passenger confirmation system and method for confirming the state of an elevator car that has been stopped after a control operation during an earthquake is performed.

  In an elevator equipped with an operation control function during an earthquake, when an earthquake detector detects an earthquake shake, the rescue operation of passengers such as the nearest floor stop is made according to the magnitude of the earthquake (acceleration of the building, etc.) Is done. At this time, an announcement telling the occurrence of the earthquake flows in the car, and after stopping at the nearest floor, an announcement is made to open the door and prompt the passenger to get off, and the lights in the car are turned off. Then, after a predetermined period of time has passed since the lighting is turned off, the door is closed to put the elevator in a dormant state, and the operation pause state is continued until an inspection operation is performed by a specialized elevator maintenance staff.

In addition, in order to prevent passenger confinement in the car, even if the door closes before the passenger gets off, by pressing the door open button in the car, the passenger can open the door, It is configured so that passengers are not trapped in the elevator car.
Furthermore, when the car is located on the stop floor, means for displaying the presence or absence of passengers in the car, or means for opening the car door with the stop button on the stop floor when the car is located on the stop floor An apparatus provided with (or means for opening a car door in a monitoring room) has also been proposed (see, for example, Patent Document 1).

  In Patent Document 1, in order to prevent passengers from being left behind in an elevator car that has been suspended by an earthquake-controlled operation device, there are provided means for opening an external display and a car door depending on the presence or absence of passengers in the car. However, there was a problem that it was affected by the accuracy of detecting the presence or absence of passengers in the car.

JP-A 61-169470

  In the conventional elevator apparatus, if the operation is stopped after the nearest floor stop by the control operation at the time of earthquake, the state in the car cannot be confirmed until the inspection work by a professional elevator maintenance worker is performed. As described, when the car is located on the stop floor, there is a means for externally displaying the presence or absence of passengers in the car, and a means for opening the car door by enabling the stop button on the stop floor, The presence of passengers was confirmed.

As described above, depending on the presence / absence of passengers in the car, the display to the outside and the activation of the door opening means of the car are judged, which affects the accuracy of detecting the presence / absence of passengers in the car. In response, there is a problem that there is a possibility of erroneous detection.
In addition, as a result of false detection, even though the passenger in the car was rescued, it was judged that there was a passenger in the car and the display to the outside was continued, or a passenger with a light weight like a child in the car There was also a problem that the rescue of passengers from the car was delayed because it was judged that there were no passengers in the car, even though they were present.

  In addition, since the hall button on the stop floor is enabled, the state where the passenger can get in the car will continue even though the elevator is in the stop state, so it is misunderstood that the passenger can use the elevator after the earthquake. There was a problem that there might be a secondary disaster due to the concentration of passengers at the landing.

  The present invention has been made to solve the above-described problems. In an elevator that has stopped and stopped after the control operation during an earthquake, a car from a landing before a dedicated elevator maintenance staff arrives. It is an object of the present invention to obtain an elevator passenger confirmation system and method that reliably confirms the presence or absence of passengers, evacuates passengers, guides evacuation completion information after completion of evacuation, and prevents the opening and closing of unnecessary cars.

  The elevator passenger confirmation system according to the present invention stores a weighing device for detecting the weight in an elevator car that has stopped and stopped at the nearest floor by an earthquake-controlled operation when an earthquake occurs, and stores an elevator operation history before the occurrence of an earthquake. A passenger unattended detection device for determining the presence or absence of a passenger in the car based on the operation history storage device, the weight signal from the scale device, and the history signal from the operation history storage device, and the door opening of the resting elevator The passenger confirmation operation device is activated only when the detection result of the unmanned passenger detection device indicates that there is a passenger.

  According to the present invention, even before a specialized elevator maintenance staff arrives, the passenger is left in the elevator car stopped by the earthquake control operation device by surely checking the presence or absence of the passenger in the car. Can be surely prevented, and after the evacuation is completed, the evacuation completion information can be guided and unnecessary door opening and closing of the car can be prevented.

Next, the operation procedure of the elevator passenger confirmation system according to Embodiment 1 of the present invention shown in FIGS. 1 to 3 will be described with reference to FIG.
FIG. 4 is a flowchart showing an operation procedure of the elevator passenger confirmation system according to Embodiment 1 of the present invention.

  In FIG. 4, first, when an earthquake occurs, the seismic detector 6 senses the shaking of the earthquake (step S101), and the seismic control operation device 15 and the elevator control device 5 respond to the magnitude of the shaking at the time of the earthquake. Control operation is performed (step S102).

  That is, according to a predetermined sequence by the earthquake control operation device 15, the elevator control device 5 stops the car at the nearest floor if the elevator is running when the detected earthquake vibration is greater than or equal to the predetermined level. (Step S103), the door of the elevator is fully opened (Step S104).

At this time, an announcement notifying the occurrence of an earthquake and an announcement prompting the passenger to get off the car flow in the car on which the passenger is riding, thereby assisting smooth passenger evacuation.
Further, in order to prompt passengers in the car to get off, the car interior light is turned off, and the door open button in the car is turned on so that the passengers in the car can operate even when the car is turned off (step S105).

Subsequently, after a lapse of a predetermined time (15 to 20 seconds) during which the passenger can get off, the elevator door is started to be closed (step S106), the elevator door is fully closed (step S107), and the operation is stopped. (Step S108).
As a result, the elevator cannot be used until the inspection work by a specialized elevator maintenance worker is performed.

Next, it is determined whether or not the door opening button has been pressed in the car (step S109), and it is determined that the door opening button has been pressed in the car by the passenger remaining in the car (that is, Yes). For example, the process returns to the previous stage of step S106 and the door opening / closing process is performed again.
On the other hand, if it is determined in step S109 that the door open button in the car is not operated (that is, No), it is assumed that there are no passengers left in the car and the operation is stopped (step S110).

Further, while the operation is suspended, the display of the floor where the car is suspended is blinked in the floor display of the hall display device 12 installed on the hall operating panel 10 (step S111).
Next, it is determined whether or not a passenger confirmation operation has been performed by the passenger confirmation operation device 16 (passenger confirmation operation device 16 has been validated) while the operation is suspended (step S112). If it is determined that the passenger confirmation operation has not been performed (ie, No), the process returns to step S111.

  On the other hand, if it is determined in step S112 that the passenger confirmation operation has been performed (that is, Yes), then it is confirmed whether the car is unmanned (step S113), and the car is unmanned ( That is, if it determines with Yes), it will return to step S111.

On the other hand, if it is determined in step S113 that there is a passenger in the car (that is, No), the passenger confirmation operation (step S112) is validated and a rescue operation in the car is performed (step S114).
Specifically, the door of the elevator is fully opened for a predetermined time so that the elevator maintenance staff can check the inside of the car and the passenger can be rescued from the inside of the car.

  Next, it is determined whether or not rescue is completed in the car based on whether or not the rescue completion operation is performed by the rescue completion operation device 17 (step S115). If it is determined as incomplete (ie, No), the process returns to step S114.

On the other hand, if it is determined in step S115 that the rescue completion operation device 17 has been operated and the rescue has been completed (that is, Yes), the door is fully closed, the rescue completion external display device 18 is driven, Rescue completion display is performed (step S116).
Finally, the operation stop is continued again (step S117), and the processing routine of FIG. 4 is terminated.

  The passenger confirmation in the car will be specifically described. After the passenger confirmation operation is performed in step S112, the passenger unmanned detection device 80 detects the weight signal of the scale device 8 and the history from the operation history storage device 9 in step S113. The presence of passengers is confirmed based on the information.

  Thereafter, if it is determined that there are passengers in the car, a rescue operation in the car (step S114) is performed. If it is determined that there are no passengers in the car, unnecessary opening and closing operations of the elevator door are avoided. In order to do so, the passenger confirmation operation in the car is not performed.

In addition, the passenger unmanned detection device 80 includes a determination map as shown in FIG. 5 in order to confirm the passenger unmanned in the car.
FIG. 5 is an explanatory diagram showing a determination map for elevator passenger unattended determination stored in advance in the passenger unattended detection device 80.

  The passenger unmanned detector 80 is a combination table of weight information (passenger presence / absence determination result) by the scale device 8 and history information (travel history, landing call registration, in-car destination registration, etc.) from the driving history storage device 9 ( From FIG. 5), the passenger unattended determination (presence determination) is uniquely performed according to the conditions of each information signal.

  In FIG. 5, for example, even if the passenger determination by the scale device 8 is “no passenger”, if the history information is “with travel history” or “with landing call registration”, the final determination is “with passenger”. Make a good judgment.

In FIG. 5, the determination by the balance device 8 shows only two patterns of “with passenger” and “without passenger”, but in general, the detection accuracy of the balance device 8 deteriorates due to secular change. In some cases, there is a possibility that a change due to secular change is erroneously determined as being a passenger. Therefore, in order to avoid erroneous determination, a plurality of determinations by the scale device 8 may be prepared.
For example, if it is not possible to distinguish between changes due to secular changes or passengers, and if there is no travel, no landing call registration, or no in-car destination registration, the final determination is made as "no passengers". You may do it.

  In addition, the passenger unmanned detection device 80 stores the weight signal from the weighing device 8 when the elevator is installed, for example, when the elevator is installed, in order to make a determination based on the weight signal from the weighing device 8. Thereby, the passenger unmanned state can be detected by comparing the weight signal when the passenger confirmation operation is performed with the stored weight signal of the unmanned state.

In this way, only when there are passengers in the car, the opening and closing of the doors of the elevator in the operation stop state is permitted, so that the passengers can be rescued when necessary and the opening and closing of unnecessary doors is prevented. Can do.
Even when the scale device 8 with poor detection accuracy is used, the passenger confirmation accuracy can be improved by the combined determination with the operation history storage device 9.

  The passenger unmanned detection device 80 determines not only a weight signal from the scale device 8 but also an unoccupied passenger from the image information using, for example, an image of a camera (not shown) installed in the car as input information. It may be configured.

The passenger confirmation operation (step S112) is a normal elevator, for example, by continuously pressing the hall call button device 11 of the hall operation panel 10 on the floor where the elevator is stopped and the car is stopped for 15 seconds. A unique operation form different from the operation at the time of use may be set, and when the unique operation is performed, the elevator door for checking passengers in the car may be fully opened.
At this time, in order to easily understand the situation in the car, the in-car light that has been turned off may be turned on.

  Moreover, although the example which implement | achieved the passenger confirmation operation and the door opening continuation operation by the button operation normally installed in the elevator was shown here, in the hall 7 or the car 1 so as to correspond to each operation. New buttons may be installed individually.

  Further, in the in-car rescue completion determination (step S115), it is effective when the in-car rescue completion operation is performed, and the fact that the rescue of passengers in the car 1 has been completed is displayed on the landing 7 or outside ( In step S116), the in-car rescue operation (step S114) may be set to repeat the same operation as the passenger confirmation operation (step S112) again. Or after passenger confirmation operation (step S112) is performed, you may make it transfer to rescue operation in a car automatically after the predetermined time.

  Furthermore, in the flowchart of FIG. 4, after the rescue completion display in the car (step S116), the operation suspension is continued (step S117), and it is configured to prevent unnecessary opening and closing of the door after the rescue is completed. Even after the completion of the rescue in the car, a similar rescue operation may be enabled when a passenger confirmation operation is performed.

As described above, the elevator passenger confirmation system according to the first embodiment of the present invention (FIGS. 1 to 5) is provided in the elevator car 1 that has stopped and stopped at the nearest floor by the control operation during an earthquake. Based on the weighing device 8 for detecting the weight, the operation history storage device 9 for storing the elevator operation history before the occurrence of the earthquake, the weight signal from the weighing device 8, and the history signal from the operation history storage device 9, 1 is provided with an unmanned passenger detection device 80 for determining the presence or absence of passengers in 1 and a passenger confirmation operation device 16 for enabling the door opening of a resting elevator.

  Furthermore, the elevator passenger confirmation method according to Embodiment 1 (FIG. 4) of the present invention includes a step of stopping the elevator car at the nearest floor by the control operation at the time of the earthquake, and a car stopped at the nearest floor. A step of fully opening the door, a step of fully closing the car door after a predetermined time has elapsed since the car door was fully opened, and pausing the elevator car, and whether the door opening button in the paused car has been operated A step of determining whether a door opening / closing button is operated, a step of opening / closing a car door, a step of determining whether a passenger confirmation operation is performed when the door opening button is not operated, A step of determining whether or not the car is unmanned when a passenger confirmation operation is performed, a step of performing a rescue operation of a passenger in the car when the car is not unmanned, and a The rescue operation is complete And determining a whether or, if the passenger rescue operation in the car is completed, and includes a step of displaying the rescue complete, the.

  In this way, in an elevator that has been stopped after detecting the shaking of the earthquake and stopped at the nearest floor by control operation during an earthquake, the passenger confirmation operation was performed on the floor where the elevator was stopped before inspection work by a specialized elevator maintenance worker was performed. When (step S112) is performed, the elevator doors are fully opened, the interior of the car 1 is confirmed, and the passenger confirmation operation is performed (validated) based on the determination result (with passengers) of the unmanned passenger detection device 80. ).

This ensures that passengers are not left behind in the elevator car 1 that has been stopped by the control device 15 during an earthquake, and after completion of evacuation of passengers, the completion information is guided and unnecessary door opening and closing of the car is prevented. To do.
That is, even before a special elevator maintenance staff arrives, the presence or absence of passengers in the car 1 can be confirmed with certainty, and the passenger confirmation operation is shifted to the passenger confirmation operation based on the determination of the passenger unmanned detection device 80. Unnecessary door opening and closing when the car is unattended can be prevented.
