Description

  The present invention relates to an elevator rescue operation system that performs a rescue operation using an elevator of each unit when a disaster such as a fire occurs in a building.

  With the recent rise of buildings, the elevator plays an indispensable role as a means of moving the building vertically. Elevators also play an important role for people with physical disabilities, such as wheelchair users, to move from floor to floor.

  Here, in the event of a fire, there is currently an operation such as stopping the operation after traveling the elevator to the evacuation floor, and there is no legal restriction, but the elevator is actively used as an evacuation means. There is no current situation. For this reason, people who remain in the building must use the stairs to move to the evacuation floor, take time to evacuate, and have the risk of injury by falling on the stairs.

  Therefore, in recent years, there has been an increasing demand for positively using elevators as evacuation means in the event of a fire. For example, Patent Document 1 discloses a method in which an elevator is operated in the event of a fire, and a car is preferentially dispatched to a wheelchair user's stay floor.

JP 2005-335893 A

  In the event of a fire, it is necessary to evacuate the people on each floor as soon as possible by turning as many elevator cars as possible (turning back). In this case, disaster vulnerable persons such as wheelchair users are difficult to evacuate using stairs on the way, so it is necessary to carry them to the evacuation floor (usually the first floor). However, if the car is driven to the evacuation floor, it takes time to go around, so that there is a problem that the rescue of the residents in each floor is delayed.

  In addition, in the above-mentioned Patent Document 1, although the dispatch of the car is controlled according to the situation of the landing on each floor (the number of waiting persons and the presence or absence of wheelchair users), the subsequent driving method is not particularly mentioned.

  The present invention has been made in view of the above points. In addition to transporting general users to a safe floor as soon as possible, disaster victims such as wheelchair users can be transported to an evacuation floor to be present on each floor. An object of the present invention is to provide an elevator rescue operation system that can efficiently rescue the building staff.

  The present invention relates to a rescue operation system for elevators used in a building where a plurality of elevators including at least one wheelchair is arranged in parallel, and when a disaster occurs in the building, the disaster is detected. Detection means, landing call registration means for registering a general call or wheelchair call at the landing on each floor, and if the general call is registered by the landing call registration means in the event of a fire, Assigning the general call, and when the wheelchair call is registered, assignment control means for assigning the wheelchair call to a car that satisfies a predetermined condition among the cars including the wheelchair car, and the assignment control means The unit that responds to the wheelchair call is operated directly to the preset evacuation floor, and the unit that responds to the general call is used as the disaster detection means. Characterized in that than the detected fire place and and a rescue operation means for operating to secure the floor below me.

  According to the present invention, the car responding to the wheelchair call is directly operated to the evacuation floor, and the car responding to the general call is driven to a safe floor below the place where the fire occurred. Thereby, while a general user can be carried to a safe floor as soon as possible, a disaster weak person, such as a wheelchair user, can be carried to an evacuation floor, and the residents in each floor can be rescued efficiently.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of an elevator rescue operation system according to an embodiment of the present invention.

  This system includes a group management control device 11, a fire detection device 12, a notification device 13, unit control devices 14a, 14b, 14c, etc., elevator cars 15a, 15b, 15c, and general call buttons 16a, 16b, 16c ..., wheelchair call buttons 17a, 17b, 17c ..., and load sensors 18a, 18b, 18c ...

  The group management control device 11 performs group management control on elevators of a plurality of units arranged in parallel in a building. The group management control device 11 is configured by a computer. The fire detection device 12 is installed on each floor of the building, detects the occurrence of a fire, and notifies the group management control device 11 of the occurrence location. The notification device 13 notifies an evacuation warning or the like when the fire detection device 12 detects the occurrence of a fire.

  The single controllers 14a, 14b, 14c,... Individually control the operation of the elevators of each unit, such as registration of car calls and opening / closing of doors. The single control devices 14 a, 14 b, 14 c... Are also configured by a computer in the same manner as the group management control device 11. The cars 15a, 15b, 15c, etc. move up and down in the hoistway by driving a hoisting machine (not shown), and move between the floors with passengers.

  Each of the cars 15a, 15b, 15c,... Is provided with load sensors 18a, 18b, 18c,... For detecting the loaded load, and the loaded loads detected by these load sensors 18a, 18b, 18c,. Is supplied to the group management control device 11 via the single control devices 14a, 14b, 14c.

  Further, the general call buttons 16a, 16b, 16c... And the wheelchair call buttons 17a, 17b, 17c... Are installed at the landings on the floors as landing call buttons. The general call buttons 16a, 16b, 16c... Are operation buttons for general users to register hall calls. On the other hand, the wheelchair call buttons 17a, 17b, 17c,... Are operation buttons for the wheelchair user to register the hall call, and the general call buttons 16a, 16b, 16c,. Generally, it is installed at a low position.

  A signal of a hall call including information indicating the floor and destination direction of the hall and attribute information indicating a general call / wheelchair by operation of the general call buttons 16a, 16b, 16c... Or the wheelchair call buttons 17a, 17b, 17c. Is sent to the group management control device 11.

  Thereby, in the group management control apparatus 11, the elevator which should assign the said hall call based on the driving | running state of the elevator of each number machine is selected and made to respond. In this case, during normal operation, the general call is assigned to any one of the cars including the wheelchair car, and the wheelchair call is assigned to the wheelchair car. On the other hand, when a fire occurs, a general call is assigned to a machine other than the wheelchair (ie, a general car), and a wheelchair call is assigned to a wheelchair or a general car under predetermined conditions (see FIG. 5).

  Here, in the present embodiment, the group management control device 11 is provided with a control unit 21 and a storage unit 22 as a functional configuration relating to a fire occurrence.

  The control part 21 performs the process regarding the operation control of the elevator of each unit, and has the allocation control part 21a, the rescue operation part 21b, and the notification part 21c here.

  When a general call is registered in the event of a fire, the assignment control unit 21a assigns a general call to a general unit other than the wheelchair unit, and when a wheelchair call is registered, the allocation control unit 21a performs a predetermined call in each unit including the wheelchair unit. Assign wheelchair calls to units that meet the conditions.

  “Predetermined conditions” are the loading rate and response time of the car. That is, the allocation control unit 21a determines whether or not there is a unit having a predetermined loading ratio or less among the general units, and if there is no corresponding unit, assigns a wheelchair call to the wheelchair unit and applies the corresponding unit. If there is a wheelchair call, assign the wheelchair call to the quicker of the general and wheelchair units.

  The rescue operation unit 21b directly operates the unit that has responded to the wheelchair call by the allocation control unit 21a to the preset evacuation floor, and the unit that has responded to the general call is located below the fire occurrence location detected by the fire detection device 12. Drive to the safe floor. In addition, when the general call assignment is added to the car to which the wheelchair call has already been assigned, the rescue operation unit 21b directly drives the car to the evacuation floor.

  The notification unit 21c notifies various messages at the time of rescue operation. For example, when a car to which a wheelchair call has already been assigned responds to a general call, it notifies that the car is directly operated to the evacuation floor. .

  The storage unit 22 stores, as various types of information necessary for operation control of the control unit 21, information on the hall call registered at each floor and information such as the car number assigned to the hall call.

  FIG. 2 is a diagram showing the configuration of the elevator car.

  A car door 31 is provided on the front of the car 15 so as to be openable and closable, and an operation panel 32 provided with various operation buttons is provided beside the car door 31. The operation panel 32 is provided with a door opening button 34a, a door closing button 34b and the like in addition to a destination floor designation button 33 for a passenger to designate a destination floor.

  In the car 15, a display 35 for displaying a message and a speaker 36 for making a voice announcement are installed.

  Further, in the case of a wheelchair machine, an operation panel 37 for a wheelchair user is provided on a side surface in the car 15. The operation panel 37 is installed at a position that can be operated by a wheelchair user, and has a destination floor designation button 38, a door opening button 39a, a door closing button 39b, and the like, similar to the operation panel 32.

  FIG. 3 is a diagram showing the configuration of the elevator hall.

  A landing door 41 is provided at the elevator hall 19 so as to be freely opened and closed. The landing door 41 engages with the car door 31 and opens and closes when the car 15 is landed. A general call button 16 is provided in the vicinity of the landing door 41.

  The general call button 16 is an operation button for a general user to register a hall call, and specifically includes an upward direction button and a downward direction button for specifying a destination direction. In addition to the hall call button 16, a wheelchair call button 15 dedicated to a wheelchair user is provided. The wheelchair call button 15 is installed at a position that can be operated by a wheelchair user, and has an upper direction designation button and a lower direction designation button like the general call button 16a.

  An indicator 43 for displaying the current car position and the like is provided on the landing door 41. Further, a display 44 for displaying a message and a speaker 45 for making a voice announcement are installed near the landing door 41.

  Next, the operation of this system will be described.

  Now, as shown in FIG. 4, a system is assumed in which four elevators are arranged in parallel in buildings of 1F to 20F. Hereinafter, the four elevators will be referred to as “A”, “B”, “C”, and “D”, respectively, and the elevator cars will be referred to as “cars 15a, 15b, 15c, and 15d”. In addition, Unit A, Unit B, and Unit C are preset as general units, and Unit D is set as a wheelchair unit, and 1F is an evacuation floor when a fire breaks out.

(A) Allocation control FIG. 5 is a flowchart showing a processing operation related to allocation control of general calls and wheelchair calls of the management control device 11 in this system. Note that the processing shown in this flowchart is executed when the group management control device 11 which is a computer reads a predetermined program.

  When a fire occurs in the building (Yes in step S11), the fire detection device 12 detects the fire occurrence place (the floor where the fire occurred), and a detection signal is given to the group management control device 11. As a result, the control unit 21 provided in the group management control device 11 switches from the normal operation mode to the rescue operation mode (step S12), and first makes a call for a hall that is currently registered in the UP direction (upward). By canceling all of them, the resident is prohibited from moving upward (step S13).

  It should be noted that the above “call hall call” includes a general call registered by operating the general call button 16 and a wheelchair call registered by operating the wheelchair call button 17.

  In addition, when switching to the rescue operation mode, it is desirable to notify the car and the landing to that effect. In the case of notification by display, the display 35 shown in FIG. 2 and the display 44 shown in FIG. 3 are used. In the case of notification by voice, the speaker 36 shown in FIG. 2 and the speaker 45 shown in FIG. 3 are used.

  When a downward general call is newly registered on a certain floor (Yes in step S14), the group management control device 11 assigns the general call to a machine other than the wheelchair car, that is, a general car (step S15). ).

  In step S15, when there are a large number of general units, an optimal unit is selected from each unit using a general evaluation function formula, and the general call is assigned to the unit. In the example of FIG. 4, since the D machine is a wheelchair machine, it is assigned to any one of the A machine, B machine, and C machine which are general machines.

  On the other hand, when a downward wheelchair call is newly registered (Yes in step S16), the following allocation control is executed.

  That is, the group management control device 11 selects a wheelchair car and a general car with a predetermined loading ratio or less as candidates (step S17). The “below the predetermined loading ratio” specifically means 50% or less of the rated load, and this is determined in advance in consideration of the weight of the wheelchair. In other words, for general cars, car numbers that have sufficient space for wheelchair users to ride are candidates. Note that the load value of each unit is detected by the load sensors 18a, 18b, 18c... Shown in FIG.

  If the corresponding general car does not exist (No in step S18), the group management control device 11 assigns the wheelchair call to the wheelchair car (step S19).

  In step S19, when there are a large number of wheelchair cars, the most suitable car is selected from each car using a general evaluation function formula, and the wheelchair call is assigned to the car. In the example of FIG. 4, since only the No. D machine is a wheelchair No., it is assigned to the No. D machine.

  If there is a corresponding general car (Yes in step S18), the group management control device 11 assigns the wheelchair call to the car that responds quickly among the wheelchair car and the general car (step S20). For example, in FIG. 4, when the C machine is a general car that satisfies the loading condition and can respond to the wheelchair call at 19F earlier than the D car, it is assigned to the C car.

  In addition, when the loading ratio of the wheelchair unit exceeds 80%, for example, that is, when there is not enough space for the wheelchair user to get in the car, priority is given to the general unit that satisfies the loading condition. .

  Here, when the wheelchair call is assigned to the general car (Yes in Step S21), as will be described later, the general car is handled as a wheelchair and is directly operated to the evacuation floor (FIG. 6). S34). Therefore, in order to prioritize the wheelchair user's boarding when the relevant car arrives, the group management control device 11 sends a message as shown in FIG. 7 to the display 44 installed at the landing 19 of the call registration floor. It is displayed (step S22).

  By displaying such a message, when a general car responds to registration of a wheelchair call, it can be expected that a general user refrains from boarding. Note that the same message may be output as voice through the speaker 45.

  In this way, when a general call or a wheelchair call is assigned to an appropriate car in each car, assignment information indicating the result is stored in the storage unit 22 of the group management control device 11.

(B) Operation Control FIG. 6 is a flowchart showing the processing operation related to the operation control of each unit of the management control device 11 in this system. As in FIG. 5, the processing shown in this flowchart is also executed by the group management control device 11 that is a computer reading a predetermined program.

  When a certain car arrives at the call registration floor, the group management control device 11 refers to the storage unit 22 and determines whether or not it is a response to a wheelchair call (step S31). In the case of a car that has responded to a wheelchair call (Yes in step S31), the group management control device 11 automatically registers a car call on the evacuation floor for that car (step S32).

  Then, the group management control device 11 displays a message as shown in FIG. 8 on the indicator 35 installed in the car of the relevant car, notifying the passenger that the direct operation is to be made to the evacuation floor due to a fire. (Step S33), the unit is directly operated to the evacuation floor (Step S34). Note that a similar message may be output through the speaker 36.

  During direct operation, operation of car calls by users is prohibited. In addition, if a hall call (general call or wheelchair call) is registered on the middle floor, it is possible to respond appropriately. However, if the number of stops increases in response to a hall call, the lap time will be further delayed. Therefore, it is preferable to prohibit registration of a general call on a floor below the fire floor and to respond only to a wheelchair call.

  On the other hand, in the case of a car that has responded to a general call (Yes in step S35), the group management control device 11 first determines whether or not a wheelchair call has already been registered in that car (step S36).

  Here, the general call is assigned only to the general car other than the wheelchair car (see steps S14 to S15 in FIG. 5). However, a wheelchair call may be assigned to a general car depending on conditions (see steps S16 to S20 in FIG. 5).

  Therefore, when the general car responds to the general call, the wheelchair call may already be registered (Yes in step S36). In this case, the group management control device 11 displays a message as shown in FIG. 8 on the display 35 installed in the car of the relevant car, and informs the passengers that he / she will go directly to the evacuation floor to cause a fire. Notification is made (step S37), and the unit is directly operated to the evacuation floor (step S38). Note that a similar message may be output through the speaker 36.

  Further, when the car number of the evacuation floor is not registered when the general machine responds to the general call (No in step S36), the group management control device 11 is connected to the floor where the fire has occurred so as to perform the return operation as soon as possible. The lower floor is determined as a safety floor, and a car call on the safety floor is automatically registered (step S39).

  Then, the group management control device 11 displays a message as shown in FIG. 9 on the indicator 35 installed in the car of the relevant car, and the passenger stops at a safe floor on the way due to a fire. (Step S40), and the relevant machine is driven to the safety floor (step S41). Note that a similar message may be output through the speaker 36.

  Here, it is assumed that the “safety floor” is, for example, a floor at least lower than the second floor floor than the fire occurrence floor. This is because the floor directly below the fire floor is highly dangerous. As a matter of course, a lower floor may be determined as a safety floor than the second floor.

  In the example of FIG. 4, a fire occurs at 15F, and 13F below the second floor is defined as a safety floor. So, for example, when Unit C responds to a general call on the floor above 15F, if a wheelchair call is not registered, drive from there to the safety floor on 13F, open the door there and drop the passenger, It will be turned up in the upward direction.

  As described above, according to the present system, when a fire breaks out, the disaster response person such as a wheelchair user can be preferentially evacuated by directly operating the unit that responds to the wheelchair call to the evacuation floor. On the other hand, by driving to the safe floor on the way for the unit that responds only to the general call, the lap time can be shortened, and the general user can be evacuated to the safe floor as soon as possible.

  In addition, when switching to the evacuation operation mode is performed and the display to that effect is performed, the light is turned off when the evacuation operation is completed. The end of the evacuation operation mode, for example, a button for ending the evacuation operation is provided in the group management control device 11, and the elevator manager operates the button.

  In addition, the wheelchair user priority display at the landing is turned off when the corresponding car is closed after the response. Specifically, this can be realized by adding a process of turning off the light when the general machine responds to the wheelchair call after step S33 in FIG.

  In addition, the display of the destination floor (safe floor / evacuation floor) of the car in the car is turned off when it arrives at the destination floor. In addition, it is preferable to notify the passenger of getting off the vehicle from the arrival of the destination floor until the door is closed or by voice notification.

  For example, if you arrive at a safe floor and there is no car call on the evacuation floor, as shown in Fig. 10, "Please get off when the door opens. Please use the stairs after this." Such a message is displayed on the display 35 in the car.

  If you arrive at a safe floor and there is a car call on the evacuation floor, as shown in Fig. 11, "Get off when the door opens. Use the stairs. If you cannot use the card, please wait while you are in the vehicle. "Is displayed on the display 35 in the car.

  When arriving at the evacuation floor, as shown in FIG. 12, a message such as “It is an evacuation floor. Please get off when the door opens” is displayed on the display 35 in the car.

  In this system, depending on the order of assignment, both a safe floor and an evacuation floor may be set as the destination floor of the car. In that case, if the car call to the safe floor is canceled when it is decided to go to the evacuation floor, the number of stops for getting off can be reduced, so that the operation efficiency can be improved.

  Specifically, as shown in FIG. 13, when a wheelchair call is answered, it is determined whether there is a car call on a safe floor (step A11). This can be realized by adding a call cancellation (step A12).

  In addition, although the said embodiment demonstrated and assumed the rescue operation when a fire generate | occur | produced, this invention is applicable similarly, even when some disasters other than a fire generate | occur | produce in a building.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
