Japanese Unexamined Patent Publication No. 2007-254036

  In an elevator equipped with a control operation function, when an occurrence of a disaster is detected, the car may be urgently stopped in the hoistway to prevent the damage from spreading. At this time, depending on the timing of emergency stop, the car stops between the floors.

  In the thing of patent document 1, when an elevator will be in the state which can drive after an emergency stop, in order to make a passenger escape quickly outside a cage | basket | car, a passenger is alighted on the nearest floor. However, depending on the disaster that occurred, passengers had to move outside even after getting out of the car, and the nearest floor at the time of emergency stop was not necessarily the floor suitable for evacuation.

  For example, in a floor that is not serviced during normal operation, there is a case where an evacuation route is not secured or power is not supplied. When passengers get off the floor, it may take a long time to move from the floor to the outside. In addition, even when an evacuation route is secured on the nearest floor, if a long staircase or the like must be used to move from the floor to the outside, a predetermined passenger (for example, an elderly person or Injured people, wheelchair users, etc.) are burdensome, and in the worst case, passengers may not be able to move from the floor where they got off.

  The present invention has been made to solve the above-described problems. The purpose of the present invention is to make it possible to evacuate to the outdoors as easily as possible after a predetermined disaster occurs and the elevator stops urgently. It is an object of the present invention to provide an elevator control device capable of getting passengers to the appropriate floor.

  An elevator control device according to the present invention includes a disaster detection device that detects a predetermined disaster that has occurred in a building, and an emergency when an emergency car is urged based on a predetermined stop condition when a disaster is detected by the disaster detection device. The travel control device to be stopped, and when the car is urgently stopped by the travel control device, the evacuation of passengers after getting out of the car for each floor where it is legally and physically possible to run the car An evacuation floor determination device that sets priority representing ease and determines an evacuation floor based on the set priority, and the traveling control device emergency stops the car based on the stop condition, The car is driven to the evacuation floor determined by the evacuation floor determination device.

  With the elevator control device according to the present invention, after a predetermined disaster has occurred and the elevator has stopped urgently, passengers can get off to an appropriate floor so that evacuation to the outside is as easy as possible. Will be able to.

It is a block diagram which shows the control apparatus of the elevator in Embodiment 1 of this invention. It is a flowchart which shows operation | movement of the control apparatus of the elevator in Embodiment 1 of this invention.

  In order to explain the present invention in more detail, it will be described with reference to the accompanying drawings. In addition, in each figure, the same code | symbol is attached | subjected to the part which is the same or it corresponds, The duplication description is simplified or abbreviate | omitted suitably.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing an elevator control apparatus according to Embodiment 1 of the present invention. This control device has a function of performing control operation when a predetermined disaster occurs in a building.

  In FIG. 1, 1 is a disaster detection device for detecting a predetermined disaster that has occurred in a building, such as a fire, flood, or earthquake, and 2 is an elevator control panel provided in the building.

  The disaster detection device 1 outputs disaster detection information to the control panel 2 when detecting that a predetermined disaster has occurred in the building. For example, when a building is equipped with an earthquake detector that detects the occurrence of an earthquake as the disaster detection device 1, the disaster detection device 1 outputs information such as the magnitude of the earthquake that has occurred as disaster detection information. Further, when a smoke detector or a flame detector is provided as the disaster detection device 1, the disaster detection device 1 uses, for example, information such as a fire occurrence floor or a more specific fire occurrence location as disaster detection information. Output as.

  The control panel 2 has a function of controlling the operation of the elevator, such as a normal operation of the elevator and a control operation when a disaster occurs (hereinafter also referred to as “control operation during a disaster”). Specifically, the control panel 2 includes an operation mode control device 3, a travel control device 4, a restart determination device 5, an evacuation floor determination device 6, a notification control device 7, and a passenger presence / absence determination device 8.

  The operation mode control device 3 has a function of selecting an operation mode of the elevator based on input information or the like and appropriately controlling the selected operation mode. For example, when the occurrence of a disaster is not detected by the disaster detection device 1, the operation mode control device 3 selects the normal operation as the operation mode of the elevator. When the normal operation is selected by the operation mode control device 3, the control panel 2 performs control for sequentially responding the elevator (car) to calls registered from the landing or the car.

  In addition, when the occurrence of a disaster is detected by the disaster detection device 1, the operation mode control device 3 performs a disaster control operation (control operation during earthquake, control operation during fire, control operation during flooding, etc.) as an operation mode of the elevator. select. In other words, when the disaster detection information is input from the disaster detection device 1, the operation mode control device 3 selects an appropriate disaster control operation based on the input disaster detection information. Then, when the disaster mode control operation is selected by the operation mode control device 3, the control panel 2 shifts from the normal operation to the disaster control operation, and performs optimal control for the disaster that has occurred.

The traveling control device 4 has a function of appropriately controlling the traveling and stopping of the elevator car in accordance with the selected operation mode.
For example, when a disaster is detected by the disaster detection device 1, the traveling control device 4 makes an emergency stop of the elevator car based on a predetermined stop condition. In other words, when the operation control unit 3 selects the disaster control operation, the traveling control device 4 determines the type of disaster, the scale of the disaster, the state of the car (whether the vehicle is running, the car position, etc.), the safety device It is determined whether or not the stop condition is satisfied based on the state or the like. Then, the traveling control device 4 makes an emergency stop on the traveling car when the stop condition is satisfied.

  In addition, when an emergency stop of a car is performed, the car may stop in a floor (for example, a section where the landing door is not linked to the opening / closing operation of the car door and cannot be opened) depending on the stop timing. .

  The restart determination device 5 determines whether or not the car can be run again based on a predetermined restart condition when the car is stopped between the floors by the control of the travel control device 4 after the occurrence of a disaster. To do. For example, the restart determination device 5 determines whether or not the restart condition is satisfied based on the type of disaster, the scale of the disaster, the state of the safety device, and the like. Then, the restart determination device 5 determines that the car can be re-run when the restart condition is satisfied.

  The evacuation floor determination device 6 has a function of determining an evacuation floor for getting passengers in the car to get off when the car is urgently stopped by the travel control device 4. Specifically, when it is determined by the restart determination device 5 that the car can be re-traveled, the evacuation floor determination device 6 can legally and physically travel the car at that time. And a predetermined priority is set for each floor within the specified range. In addition, the legally and physically travelable range mentioned above is caused by a predetermined time range (a car must be landed within a predetermined time) according to a disaster or the like and a remaining battery capacity at the time of a power failure. It is determined by mileage restrictions. The priority represents the ease of evacuation of passengers after getting out of the car. For example, a small (or large) value is set in the order of easy evacuation after getting off. And the evacuation floor determination apparatus 6 will determine the said evacuation floor based on the set priority, if the priority of each floor is set. For example, the evacuation floor determination device 6 selects the floor having the smallest value (high priority) as the evacuation floor.

  The traveling control device 4 causes the car to travel toward the determined evacuation floor when the evacuation floor is determined by the evacuation floor determination device 6 after urgently stopping the car based on the stop condition. Then, the traveling control device 4 performs a door opening operation when the car arrives at the evacuation floor, and causes the passenger to get off to the evacuation floor.

The notification control device 7 has a function of controlling a notification device (not shown) installed in the car.
For example, when the evacuation floor is determined by the evacuation floor determination device 6 after the disaster detection device 1 detects a disaster and the car has stopped urgently (including during traveling to the evacuation floor), the notification control device 7 detects the disaster. The notification device informs that the car is traveling (running) to the evacuation floor and that the evacuation floor is a floor that can be easily evacuated after getting off. In addition, when the evacuation floor determination device 6 determines the evacuation floor, the notification control device 7 gets off at the evacuation floor, such as an evacuation method from the elevator landing on the evacuation floor and an evacuation route to go outside from the landing. Information useful for evacuation after having been performed is notified from the notification device.

  In addition, the said alerting | reporting apparatus is for alerting | reporting predetermined information to the passenger in a cage | basket | car, for example, is comprised by display apparatuses, such as a liquid crystal display.

  The passenger presence / absence determination device 8 has a function of determining the presence / absence of a passenger in the car. Even if a disaster is detected by the disaster detection device 1 and the car is stopped urgently, if there are no passengers in the car, there is no need to run the car to a floor far from the stop position. For this reason, for example, when the passenger presence / absence determination device 8 detects the absence of a passenger in the car when the car is urgently stopped based on the above stop condition, the travel control device 4 detects the floor closest to the stop position. Move the car to the floor (the nearest floor). In such a case, the evacuation floor determination device 6 may not perform the setting of the priority for each floor, or may perform predetermined control so that the priority of the nearest floor is the highest.

  On the other hand, if the presence or absence of passengers in the car is detected by the passenger presence / absence determination device 8 when the car is urgently stopped by the travel control device 4, the evacuation floor determination device 6 determines the evacuation floor based on the priority. And move the car to the evacuation floor.

  Next, the operation of the control apparatus having the above configuration will be specifically described with reference to FIG. FIG. 2 is a flowchart showing the operation of the elevator control apparatus according to Embodiment 1 of the present invention.

  The control panel 2 always determines whether or not the disaster detection apparatus 1 has detected a disaster (S101). If the disaster detection information is not input from the disaster detection device 1, the operation mode control device 3 selects the normal operation as the elevator operation mode (S102).

  On the other hand, when a disaster is detected by the disaster detection device 1, the operation mode control device 3 selects the disaster control operation as the operation mode of the elevator. Thereby, the control panel 2 starts control for stopping the elevator.

  For example, when it is not necessary to urgently stop the traveling car (ie, the above stop condition is not satisfied), for example, because the scale of the disaster that has occurred is small, the traveling control device 4 does not stop even after the disaster detection information is input. Continue running as is and stop the car on the nearest floor in the event of a disaster. Then, the control panel 2 performs control for causing the passengers to get off at the nearest floor, and then performs an elevator pausing operation to prohibit subsequent use of the elevator (from No in S103 to S104).

  On the other hand, when the disaster that has occurred is large-scale or a predetermined safety device is operating or the like, it is necessary to urgently stop the traveling car (that is, the above stop condition is satisfied). Will immediately stop the car to prevent the occurrence and spread of damage. As described above, when an emergency stop of a car is performed, the car may stop between floors depending on the timing of the stop. For this reason, if the emergency stop by the traveling control apparatus 4 is performed, the control panel 2 determines whether the car has stopped between the floors (S103).

  When the emergency stop by the traveling control device 4 is performed, if the car happens to not stop between the floors, that is, if the car stops in the section where the landing door is interlocked with the opening / closing operation of the car door (No in S103) ), The control panel 2 performs control for causing the passengers to get off at the floor, and performs a pausing operation of the elevator in order to prohibit the use of the elevator thereafter (S104).

  On the other hand, when the car stops between floors due to an emergency stop by the traveling control device 4 (Yes in S103), the control panel 2 determines whether or not the restart condition is satisfied by the restart determination device 5 (S105). . Further, when the restart condition is satisfied and the car can be re-traveled (Yes in S105), the control panel 2 determines whether there is a passenger in the car by the passenger presence / absence determination device 8 (S106). .

When the presence of a passenger is detected in S106, the control panel 2 performs control for stopping the car on an appropriate floor in consideration of the passenger evacuating to the outdoors. For this reason, if the presence of passengers is detected in S106, the evacuation floor determination device 6 selects the floor that is most easily evacuated to the outdoors, and sets the selected floor as the evacuation floor (S107).
Below, the method of setting an evacuation floor in S107 is demonstrated concretely.

When the presence of a passenger is detected in S106, the evacuation floor determination device 6 first specifies a legally and physically possible range at which the car can be run. And the refuge floor determination apparatus 6 sets the priority showing the ease of evacuation after getting off for every floor in the specified range.
Table 1 below shows an example of a priority setting method.

  As shown in Table 1, for example, the priority is set so as to increase in order of easy movement from the elevator landing to the outdoors. That is, when it is difficult to move from the elevator landing on the floor to the outside without using the elevator, a low priority is set.

  The most suitable evacuation floor is a floor that makes it easy for any passenger to evacuate to the outside after getting off, and the most important one is the main floor (entrance floor). For this reason, the evacuation floor determination apparatus 6 sets the priority of the main floor of a building the highest, for example. Further, the evacuation floor determination device 6 sets the priority of each floor so that the floors other than the main floor are higher as the floor is closer to the main floor.

  Among the floors that the evacuation floor determination device 6 determines to be able to travel legally and physically, non-service floors that do not stop during normal operation (for example, service cuts that are prohibited from stopping the car during normal operation) Floors, emergency landing entrance floors installed in the middle of express zones for emergency escape of passengers, etc.). Such a non-service floor is not suitable as an evacuation floor because there are cases where an evacuation route to the outdoors is not secured or power is not supplied. For this reason, the evacuation floor determination device 6 sets the priority of each floor so that the non-service floor is lower than the priority of the service floor that stops during normal operation.

The evacuation floor determination device 6 also considers the damage status of each floor due to the disaster that occurred when setting the priority.
For example, when a fire breaks out in a building, even if the passenger gets off the floor where the fire occurred, the passenger cannot evacuate to the outside from the landing place. For this reason, when the occurrence of a fire is detected by the disaster detection apparatus 1, the evacuation floor determination apparatus 6 is farther from the fire occurrence floor and lower than the fire occurrence floor in consideration of the fire around the building. The priority of each floor is set so that the priority of the floor of the floor becomes higher.

  In addition, when flooding occurs in a building, passengers cannot evacuate outside from the landing place even if they get off to the lowest floor. For this reason, when the occurrence of flooding is detected by the disaster detection device 1, the evacuation floor determination device 6 sets the priority of each floor so that the priority of the upper floor that is less affected by flooding is higher. To do.

  In addition, when the disaster detection apparatus 1 detects that a plurality of disasters are occurring at the same time, the evacuation floor determination apparatus 6 considers the damage situation and the degree of danger for each floor generated by each disaster, and gives priority. Can be set. For example, when a fire and another disaster occur simultaneously, the evacuation floor determination device 6 sets the priority of the fire occurrence floor so as to be lower than the priority of the non-service floor.

  On the other hand, when no passenger is detected in S106, it is not necessary to run the car to the floor away from the stop position in order to evacuate the passenger. Therefore, when no passenger is detected in S106, the evacuation floor determination device 6 sets the floor closest to the position where the car is stopped as the evacuation floor (S108).

  When the evacuation floor is set in S107 or S108, the traveling control device 4 starts traveling the car toward the evacuation floor (S109). At this time, the traveling control device 4 automatically causes the car to travel at a speed lower than the traveling speed during normal operation, for example, to prevent the elevator equipment from being damaged or causing a secondary disaster.

  Note that the priority setting function by the evacuation floor determination device 6 may be validated and the evacuation floor can be reset even after the car starts running in S109. In such a case, for example, the evacuation floor determination device 6 performs the priority update process for each floor based on various input information until the car arrives at the evacuation floor or the elevator is stopped at the evacuation floor. . When the priority is changed after the start of traveling to the evacuation floor, the evacuation floor determination device 6 determines a new evacuation floor based on the latest priority. When the evacuation floor is changed by the evacuation floor determination device 6, the traveling control device 4 causes the car to travel toward the newly determined evacuation floor.

  Further, when the evacuation floor is set in S107 or S108, the notification control device 7 outputs a control command to the notification device in the car, and provides various information useful for evacuation to passengers in the car. (S110).

  Then, when the car arrives at the evacuation floor set by the evacuation floor determination device 6 (Yes in S111), the control panel 2 performs the door opening operation to get the passengers in the car to the landing on the evacuation floor Then, the elevator is stopped on the floor (S112).

  According to the first embodiment of the present invention, even when the elevator performs an emergency stop in a disaster control operation and the car stops between the floors, if there are passengers in the car, it is optimal for evacuation to the outdoors. A new floor is selected as the evacuation floor, and traveling to the selected evacuation floor is started. For this reason, the passenger can escape to the outside in a short time after getting off at the evacuation floor, and the damage caused by the disaster can be minimized.

Further, when the evacuation floor is determined by the evacuation floor determination device 6, various information useful for evacuation is provided from the notification device in the car. For this reason, the passenger does not panic after getting off the evacuation floor, and can quickly evacuate thereafter.
Furthermore, even when the car is urgently stopped between the floors due to a disaster, if there are no passengers in the car, the car starts traveling toward the nearest floor. For this reason, the car can be stopped at an appropriate position at an early stage after a disaster has occurred, preventing unnecessary travel and causing secondary disasters (such as elevator equipment damage) due to re-traveling the car. Can be reduced.

Depending on the building, a special evacuation route to the outside is secured on the floor other than the main floor, or there is a floor on which general passengers must never get off for security reasons. There is a case. In the present embodiment, the main floor is set as the highest priority floor, and a specific description has been given for the case where a higher priority is set for a floor closer to the main floor, but this is only an example. Is. The evacuation floor determination device 6 may set an optimum priority for the building in consideration of various factors such as the structure of the building, the evacuation system, the state and role of each floor.
In some buildings, the optimum evacuation floor may change depending on the time of day. In such a case, the evacuation floor determination device 6 may set the priority for each floor in consideration of the time when the disaster occurred (the car was stopped between the floors), and select the optimum evacuation floor for that time zone. .

  The elevator control apparatus according to the present invention can be applied to an apparatus that performs a control operation when a predetermined disaster occurs in a building such as a shake caused by an earthquake or a fire.
