Description

  Embodiments of the present invention relate to an elevator evacuation operation system in the event of a fire.

  In a conventional elevator operation system, for example, when a fire occurs in a building, the elevator is moved to an evacuation floor, for example, the first floor, and after the passengers are lowered, the operation is suspended. For this reason, when there are residents etc. in the building, even if these people call the elevator in the hall, the hall call is invalidated and the elevator cannot be used as an evacuation means. In order to use the elevator as an evacuation means, firefighters must perform special operations.

  In the conventional driving system, a person on a high floor of a building or a wheelchair user cannot use an elevator as an evacuation means when a disaster occurs. Therefore, the person on the high floor of the building or the wheelchair user must wait for the firefighter to come to rescue by special driving.

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

(First embodiment)
FIG. 1 shows a schematic configuration of an elevator operation system according to the first embodiment.

  In FIG. 1, an elevator operation system includes an operation control unit 11 that performs operation control of an elevator, a plurality of landing indicators 12 that are installed in an elevator hall as a landing on each floor, and that indicate the operation status of the elevator to a user, Installed in the elevator hall and corresponding to each elevator hall in the elevator hall as a moving path of each elevator hall or car and a plurality of landing call detectors 13 that detect the call registration of passengers It comprises a plurality of fire detectors 14 to be detected and an elevator car 17 on which a passenger rides.

  The hall indicator 12 and the hall call detector 13 installed on each floor are connected to the operation control unit 11 via a transmission path 15. The landing call registration detected by the landing call detector 13 is supplied to the operation control unit 11 via the transmission path 15, and the information output from the operation control unit 11 is transmitted to each landing indicator 12 via the transmission path 15. Supplied and displayed.

  The fire detector 14 installed in the hall or hoistway of each floor is connected to the operation control unit 11 via the transmission path 16. When a fire is detected by each fire detector 14, the information is supplied to the operation control unit 11 via the transmission path 16.

  In the elevator car 17, an in-car display 18 that indicates the operation status of the elevator and a car call detector 19 that detects call registration by a passenger in the car are provided. The in-car display 18 and the car call detector 19 are connected to the operation control unit 11 through a transmission line 20. Information on in-car call registration detected by the car call detector 19 is supplied to the operation control unit 11 via the transmission path 20. Further, the information output from the operation control unit 11 is supplied to the car display 18 via the transmission path 20 and displayed.

  Further, the operation control unit 11 is connected to a storage unit 21 in which various information is stored.

  In the above configuration, the elevator evacuation operation will be described.

  In the conventional operation at the time of fire occurrence, when a fire occurrence is detected by any of the fire detectors 14 installed on each floor, the elevator operation control unit 11 moves the elevator to an evacuation floor, for example, the first floor, Remove passengers in the car and stop driving. Thereafter, the passenger call registration from the landing call detector 13 and the car call detector 19 is invalidated, and the registered calls are also canceled. For this reason, those who are on the higher floors of a building or wheelchair users cannot use the elevator as an evacuation means in the event of a fire. Therefore, these persons will evacuate after the elevator is specially operated by firefighters and they come to rescue.

  In contrast, in the first embodiment, even after the elevator stops at the evacuation floor, if the conditions such as safety are satisfied, the call of the user is validated and the elevator is turned on before the firefighter arrives. It can be used for evacuation.

  2 and 3 show the operation of the operation control unit 11 shown in FIG. 1 according to the first embodiment. As shown in FIG. 3, it is assumed that, for example, the seventh floor is a fire source.

  When the operation control unit 11 detects information indicating the occurrence of a fire output from the fire detector 14 installed on the seventh floor among the fire detectors 14 installed on each floor, the operation control unit 11 first moves the elevator to the evacuation floor, for example, 1 Move to the floor and evacuate passengers in the car.

  Thereafter, as shown in FIG. 2, in consideration of safety, the operation control unit 11 calls the landing on the floor where the fire occurred (S11), the landing call away from the evacuation floor (S12), and the landings on the floors around the evacuation floor When the call (S13) and the car call other than the evacuation floor (S14) are registered, the call registration is invalidated and the evacuation is impossible by the elevator (S16). Moreover, the operation control part 11 makes call other than step S11-S14 effective, and makes it possible to use an elevator as an evacuation means before a firefighter arrives (S15).

  Specifically, when the operation control unit 11 detects a call from the 7th floor landing call detector 13 in which the fire detector 14 is operated (S11), the control is shifted to step S16, and this landing call is invalidated. Thus, evacuation by an elevator is impossible ((1) shown in FIG. 3). The car call on the seventh floor is also invalidated (S14-S16).

  Next, when the operation control unit 11 detects a landing call away from the evacuation floor (S12), the call is invalid because the call is for a purpose other than evacuation (S16). That is, when the first floor is the lowest floor and the evacuation floor, the operation control unit 11 responds to the call in the down direction from the landing call detector 13 toward the evacuation floor, but the call in the up direction is invalid. (FIG. 3 (2)).

  Furthermore, since the operation control unit 11 restricts the users to those who are on the higher floors, that is, those who are on the floor away from the evacuation floor, all the landing calls around the evacuation floor are invalidated and the users are limited. Therefore, when the evacuation floor is the first floor, when a landing call from the lower floor landing call detector 13 such as the second floor, the third floor, etc. is detected (S12), even if the call is in the evacuation floor direction (down direction) It is invalidated (S16, FIG. 3 (3)).

  Further, when the operation control unit 11 detects that the car call other than the evacuation floor is registered by the car call detector 19 (S14), all calls are invalid because they are used for purposes other than evacuation. (S16).

  However, the car call on the evacuation floor is not invalidated (S14-S15), and the operation control unit 11 automatically registers the car call on the evacuation floor when the platform call is moved to other than the evacuation floor (FIG. 3 (4)). )).

FIG. 4 shows an example of a control table generated by the elevator operation control unit 11 when a fire occurs. This control table is generated according to the floor where the fire occurred. The control table shown in FIG. 4 shows an example when a fire is detected by the fire detector 14 installed on the seventh floor, as shown in FIG. The operation control unit 11 generates a control table as shown in FIG. 4 according to the determination conditions considering safety, usage priority, and the like based on the information on the fire occurrence floor. In FIG. 4, data “0” indicates validity , and data “1” indicates invalidity . This control table is stored in the storage unit 21, for example. The operation control part 11 performs the operation | movement shown in FIG. 2 according to this control table.

  As mentioned above, when a fire breaks out from the 7th floor, those who are on the floor above the 7th floor and those who are on the 6th floor to the 4th floor are effective to use the landing in the down direction and use the elevator It is possible to evacuate. In other words, those on the third and second floors use the stairs to evacuate and give priority to the use of elevators by those on higher floors.

  According to the first embodiment, after a car is moved to an evacuation floor by a normal evacuation operation in the event of a fire, firefighters are considered in consideration of safety and priority of use for floors where no fire has occurred. The elevator can be used as an evacuation means even before the arriving.

  In addition, users are limited to those who are on the higher floors of the building, that is, those who are on the floor far from the evacuation floor. For this reason, it can prevent that an elevator is abused and can give priority to the evacuation of the person who is on the high floor which requires an emergency.

(Second Embodiment)
FIG. 5 shows a schematic configuration of the elevator operation system according to the second embodiment, and FIG. 6 shows an example of the operation of the second embodiment. 5 and 6, the same parts as those of the first embodiment are denoted by the same reference numerals.

FIG. 5 shows a configuration in which a hall call detector 23 for wheelchair users and a car call detector 22 for wheelchair users are added to the configuration shown in FIG. Other configurations are the same as those in FIG. 1, but are omitted in FIG. The hall call detector 23 for wheelchair users and the car call detector 22 for wheelchair users are connected to the elevator operation control unit 11 via transmission paths 15 and 20, respectively, so that information can be transmitted. Yes.

  When the evacuation operation described in the first embodiment is executed, the operation control unit 11 restricts users to those who are on a higher floor away from the evacuation floor, so all hall calls around the evacuation floor are invalidated. Yes. For this reason, when the evacuation floor is the first floor, the hall call detected from the lower level hall call detector 13 such as the second floor, the third floor, etc. is invalidated in the down direction (FIG. 2S13, FIG. 3 (3)). And FIG. 4). Accordingly, wheelchair users in lower floors such as the second floor and the third floor cannot evacuate as a result because it is difficult to evacuate on the stairs.

  Therefore, in the second embodiment, in the case of a landing call by a wheelchair user, the landing call is valid even on a floor near the evacuation floor.

As shown in FIG. 5, the landing call detection 13 installed in the elevator hall has a specification in which a call detector 23 for wheelchair users is provided. When this wheelchair user landing call detector 23 is operated and a call by a wheelchair passenger is detected as shown in step S21 in FIG. 6, the operation control unit 11 of the elevator has no problem with safety. The call is valid even around the evacuation floor. That is, if the call generation floor is not an evacuation floor (first floor) or a fire occurrence floor, the call is valid even around the evacuation floor. That is, even if the lowest floor is a specification of the first floor and a down call from the second floor or the third floor, if the call is made by a wheelchair user, the elevator can be used as an evacuation means.

According to the said 2nd Embodiment, even if it is a call of the vicinity of an evacuation floor, if it is a call by the landing call detector 23 for wheelchair users, it will make it effective and will drive | operate an elevator. For this reason, wheelchair users in the vicinity of the evacuation floor can be evacuated by the elevator.

(Third embodiment)
FIG. 7 shows a third embodiment. When the evacuation operation is executed by the method shown in the first embodiment, the operation control unit 11 uses all the hall calls in the direction away from the evacuation floor and the car calls other than the evacuation floor, which are purposes other than evacuation. Invalid. For example, when the first floor is the lowest floor and the evacuation floor, the operation control unit 11 responds to the hall call in the down direction detected by the landing call detector 13, but invalidates the hall call in the up direction (see FIG. 2S12, FIG. 3 (2) and FIG. 4). When a car call other than the evacuation floor is registered by the car call detector 19, the operation control unit 11 invalidates all the car calls other than the evacuation floor (FIG. 2S14, FIG. 3 (4) and FIG. 4). ).

  On the other hand, the third embodiment makes the above call effective when the purpose is to rescue elderly people and wheelchair users who are difficult to evacuate on stairs.

Specifically, as shown in FIG. 7, when the hall call detector 23 for wheelchair users shown in FIG. 5 detects a hall call on the evacuation floor (S31), the operation control unit 11 makes the safety If there are no problems, rescue operation is performed.

  That is, as shown in FIG. 7, it is not a call of the fire occurrence floor (S11) but a landing call away from the evacuation floor (S12), and the hall call for wheelchair users is the evacuation floor. In the case (S31), the operation control unit 11 validates the hall call, responds to the evacuation floor, and opens the door. After responding to this hall call, up to one car call registration for wheelchair users is validated (S31), and rescue operation is performed (S15). Accordingly, the operation control unit 11 operates the car to the floor registered by the car call detector 22 for wheelchair users.

  Depending on the elevator system, there is a case where a landing call detector or a car call detector for wheelchair users is not installed. In such a case, it may be specified that the call is a landing call or car call for a wheelchair user by long pressing a button of a normal landing call detector or car call detector. With this configuration, a wheelchair user's landing call or car call can be registered by a person who has recognized this rule.

According to the third embodiment, when the hall call detector 23 for wheelchair users detects a hall call in the up direction on the evacuation floor, one car call registration for wheelchair users is valid. . For this reason, an elevator can be used for the purpose of rescue of wheelchair users and the like, and it is possible to rescue elderly people and wheelchair users who are difficult to evacuate using stairs.

(Fourth embodiment)
In the third embodiment, whether or not the elevator user is a wheelchair user is determined by the hall call detector 23 for the wheelchair user and the car call detector 22. However, both call detectors can be used by ordinary users. For this reason, there is a possibility that a person other than the wheelchair user registers the call, or registers the call to the floor where there is no wheelchair user and uses the elevator.

Therefore, in the fourth embodiment, the operation control unit 11 is made to recognize the floor where the wheelchair user is present in advance, and the hall call by the landing call detector 23 for wheelchair users other than the registered floor is invalidated. And restrict the use of general users.

  FIG. 8 shows a schematic configuration of the elevator operation system according to the fourth embodiment, and the same parts as those in FIG.

  In FIG. 8, an operation control unit 11 that controls the operation of the elevator includes, for example, an elevator monitoring device 31 that is used by an administrator for monitoring the elevator, a dedicated maintenance device 32 that is used by the maintenance staff for elevator maintenance, and an elevator. A management center 33 for remote management and a storage unit 21 are connected. Information from the monitoring device 31, the maintenance device 32, and the elevator management center 33 is recorded in the storage unit 21 via the operation control unit 11 by the transmission path 34. In FIG. 8, other configurations are the same as those in FIG. 1, but are omitted in FIG.

  In the above configuration, the elevator operation control unit 11 is made to recognize in advance the floor where the wheelchair user is present. Specifically, the monitoring device 31, the maintenance device 32, and the management center 33 send the floor information of the wheelchair user to the operation control unit 11 via the transmission path 34. The operation control unit 11 records the sent floor information in the storage unit 21.

The operation control unit 11 invalidates the call registration from the hall call detector 23 and the car call detector 22 for wheelchair users other than the recorded floor.

FIG. 9 shows the operation of the fourth embodiment, and the same parts as those in FIG. As shown in FIG. 9, when the hall call detector 23 for wheelchair users detects a hall call (S41), the operation control unit 11 refers to the floor information recorded in the storage unit 21 and uses the wheelchair. It is determined whether or not the floor on which the passenger hall call detector 23 detects the hall call is a pre-registered floor (S42). As a result of this determination, when the hall call is for a wheelchair user on the floor registered in advance, the operation control unit 11 operates the car to the floor where the hall call is generated and opens the door. After the response to the hall call, for example, up to one car call registration by the car call detector 22 for wheelchair users is validated. Accordingly, when the evacuation floor is registered by the car call detector 22 for wheelchair users, the operation control unit 11 operates the car to the evacuation floor.

According to the fourth embodiment, the floor where the wheelchair user is present is recorded in the storage unit 21 in advance, and the hall call detected by the wheelchair user landing call detector 23 is recorded in the storage unit 21. If it is detected on the floor, the evacuation operation is performed. For this reason, hall calls for wheelchair users by non-recorded floors can be invalidated, and an elevator can be used for the purpose of rescue of wheelchair users. Therefore, priority can be given to evacuation of wheelchair users who are difficult to evacuate using stairs.

(Fifth embodiment)
FIG. 10 shows the fifth embodiment, and the same parts as those in the first and second embodiments are denoted by the same reference numerals. In the fifth embodiment, the apparatus configuration is the same as that shown in FIG.

  For example, in the first embodiment, when the evacuation operation is performed, the elevator operation control unit 11 prioritizes the use of those who are on the higher floors away from the evacuation floor, so all hall calls around the evacuation floor are invalidated. (S13). For this reason, when the evacuation floor is the first floor, the landing call detected by the lower floor landing call detector 13 such as the second floor, the third floor, etc. is invalidated even in the down direction (shown in FIG. 3 ( 3), FIG. 4).

  Therefore, in the fifth embodiment, when the evacuation of a user with high use priority is completed, the user with low use priority also permits the user with low use priority to use the elevator as an evacuation means. .

  Specifically, as shown in FIG. 10, the operation control unit 11 does not detect a call registration in the down direction from a landing call detector 13 on a higher floor away from the evacuation floor for a predetermined time (for example, 5 minutes). (S12) The call registration in the down direction from the landing call detector 13 on the lower floor around the evacuation floor is validated (S13, S51, S14, S15). That is, when a hall call in the down direction is detected from the landing call detector 13 around the evacuation floor (S13), it is determined whether or not the timer has counted for 5 minutes or more (S51) and counted for 5 minutes or more. If the call is not a car other than the evacuation floor (S14), the call in the down direction is validated (S15), and the car is moved to the floor where the landing call is detected and is on a floor around the evacuation floor Can be evacuated.

  If the timer count does not exceed 5 minutes in step S51, the call in the down direction from the landing call detector 13 around the evacuation floor is invalidated (S16).

  Furthermore, if the landing call detector 13 around the evacuation floor is not detected in step S13, that is, if a call on the higher floor is detected, the timer is cleared (S52), and the control shifts to step S14.

  In order to execute the above operation, the operation control unit 11 includes a timer configured by software, for example. This timer starts counting when no call registration on the upper floor is detected, and is cleared when no call around the evacuation floor is detected. The specified time set in the timer is set in the operation control unit 11 using, for example, the monitoring device 31, the maintenance device 32, and the management center 33 shown in FIG.

  According to the fifth embodiment, when the evacuation of a user with high use priority located on the floor away from the evacuation floor is completed, the user with low use priority located on the floor around the evacuation floor is also lifted. Is allowed to be used as an evacuation means. Therefore, the elevator can be used effectively.

(Sixth embodiment)
11 and 12 show a sixth embodiment.

  By restricting landing calls and car calls by the methods shown in the first to fifth embodiments, it is possible to perform an evacuation operation considering safety and priority of use in the event of a fire. At this time, there are floors where call registration is possible and floors where call registration is impossible, so the user may be confused or not mistaken for why the call cannot be registered.

  Therefore, as shown in FIG. 11, during the evacuation operation, the elevator operation control unit 11 outputs a display such as “up call registration is not possible” to the landing display 12.

  Further, as shown in FIG. 12, a display such as “cannot call registration in car” is output to the in-car display 18, and the floor buttons 19a other than the evacuation floor are turned off. FIG. 12 shows that the floor button 19a on the first floor as the evacuation floor is turned on and the floor buttons 19a on the second to ninth floors are turned off.

  Specifically, the operation control unit 11 controls the display state of the landing display 12, the car display 18, and the floor button 19a according to, for example, the table shown in FIG. 4 generated when a fire occurs.

  Note that the displays shown in FIGS. 11 and 12 are examples and can be modified.

  According to the sixth embodiment, during the evacuation operation, the landing indicator 12 and the car indicator 18 indicate that the call registration cannot be performed, and the floor button 19a in the car is evacuated. Only the floor is lit and the other floors are unlit. Accordingly, it is possible to accurately notify the user of the current situation.

  In addition, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments.
