(First embodiment)
FIG. 1 is a diagram schematically showing a configuration of an elevator system according to the first embodiment.
The elevator system according to the present embodiment includes an elevator control device 11 and a car 12.

  The elevator control device 11 is installed in a machine room or the like at the top of the building 14 and controls the entire elevator. In a machine roomless type elevator having no machine room, the elevator control device 11 is provided in the hoistway 16.

  The car 12 moves up and down in the hoistway 16 via the ropes 15 by driving a hoist (not shown) under the control of the elevator control device 11. A camera 13 is installed in the car 12.

  The camera 13 is installed, for example, on the ceiling surface of the car 12 and continuously captures the state of the car room while the car 12 is operating. In addition, the installation place of the camera 13 is not limited to the ceiling surface, but may be any place as long as the entire car can be photographed. The camera 13 is connected to the elevator control device 11 via a transmission cable (not shown).

  On the other hand, hall call buttons 18a, 18b, 18c... And cameras 19a, 19b, 19c... Are installed at the halls 17a, 17b, 17c.

  The hall call buttons 18a, 18b, 18c... Are buttons for the user to register a hall call. The “hall call” is a signal of a call registered by operating a hall call button installed at a hall on each floor, and includes information on a registered floor and a destination direction. On the other hand, the "car call" is a signal of a call registered by operating a destination call button provided in the car room, and includes information on a destination floor.

  The cameras 19a, 19b, 19c... Continuously photograph the state of the landings 17a, 17b, 17c. The cameras 19a, 19b, 19c... May be installed at any location as long as the entire hall can be photographed for each floor. The hall call buttons 18a, 18b, 18c ... and the cameras 19a, 19b, 19c ... are connected to the elevator control device 11 via a transmission cable (not shown).

FIG. 2 is a diagram showing the configuration of the car 12.
A car door 21 is installed in front of the car 12 and opens and closes by driving a door motor (not shown). In the vicinity of the car door 21, a car operation panel 24, a display 25, and the like are installed. On the car operation panel 24, various operation buttons including a plurality of destination floor buttons 22 corresponding to each floor and door opening / closing buttons 23a and 23b are provided. The display 25 displays various messages and the like to the users in the car 12 in addition to the current position and the driving direction of the car 12 and the driving state such as the destination floor.

  In the car 12, the camera 13 shown in FIG. 1 and an announcement device 26 for notifying a user in the car 12 by voice are installed.

  FIG. 3 is a block diagram illustrating a functional configuration of the elevator control device 11. Although FIG. 3 shows the hall call button 18 and the camera 19 installed at the hall 17 on an arbitrary floor, actually, the hall call buttons 18a, 18b, 18a, 18b, installed on the halls 17a, 17b, 17c,. 18c and cameras 19a, 19b, 19c.

  The elevator control device 11 includes an image processing unit 31, a storage unit 32, a boarding determination unit 33, an operation control unit 34, and a notification unit 35.

  The image processing unit 31 analyzes in real time an image (video) captured by the camera 13 in the car 12 and an image (video) captured by the camera 19 in the landing 17. The image processing unit 31 has a boarding rate detection unit 31a and a waiting person detection unit 31b.

  The occupancy rate detection unit 31a detects an occupancy rate for each area of the car 12 based on an analysis result of an image (video) captured by the camera 13 in the car 12. The method of detecting the occupancy rate by the occupancy rate detection unit 31a will be described later with reference to FIGS. The waiting number detection unit 31b detects the number of users (the waiting number) waiting for the arrival of the car 12 at the landing 17 based on the image (video) captured by the camera 19 of the landing 17.

  The storage unit 32 includes, for example, a ROM and a RAM, and stores various data necessary for processing of the elevator control device 11, such as a control program. The storage unit 32 has a call management table 32a and a learning table 32b.

  The call management table 32a manages information on hall calls registered by the user at the hall 17. FIG. 4 shows an example of the call management table 32a. The hall call has registered floor and destination direction information. The “registered floor” is the floor on which the user has registered the hall call by pressing down the hall call button 18, that is, the floor on which the user gets on the car 12, and is also called a call registration floor. The “destination direction” is a direction in which the user goes on the car 12. Specifically, the hall call button 18 has an up button and a down button, and when the up button is pressed, the information of the up direction is stored in the call management table 32a, and when the down button is pressed, Is stored in the call management table 32a in the downward direction.

  The learning table 32b is a table in which the presence / absence of the user's boarding with respect to the combination of the boarding rate of each area of the car 12 and the number of people waiting in the hall 17 is learned.

Here, a method of detecting the occupancy rate will be described.
The boarding rate detection unit 31a divides the boarding space of the car 12 into a plurality of areas, and obtains the user's boarding rate for each of these areas. The area where the riding space of the car 12 is divided includes at least an area in front of the door of the car 12. This is because, in general, users are often concentrated in front of the door, and the occupancy rate in the area in front of the door greatly affects the ride of the user waiting at the landing.

  FIG. 5 shows an example in which the boarding space (car floor) of the car 12 is divided into four areas A to D. Areas A and B are on the front side (door side) of the car 12 and areas C and D are on the rear side (back side) of the car 12 and have the same area.

  Now, it is assumed that a hall call is registered at the hall 17 on an arbitrary floor, and the car 12 responds to the hall call.

  It is assumed that the user is in the area A of the car 12. P in the figure schematically represents a two-dimensional image of the user taken by the camera 13 from the ceiling. The ratio of the area of the image P of the user to the area of the area A is determined as the riding rate of the area A. If a large number of users are in area A, the occupancy rate in area A increases. The same applies to the other areas B, C, and D, and the occupancy rate is determined by the number of users occupying each area.

  When the user is riding over a plurality of areas, the ratio of the image P of the user in each area may be obtained. For example, as shown in FIG. 6, when the user is riding across the area A and the area B, the ratio of the image P of the user in the area A is determined as the riding rate of the area A, The ratio of the image P of the user in the area B is determined as the riding rate of the area B.

  The boarding space of the car 12 is not limited to four and may be divided more finely. In general, a user often gets in front of the door of the car 12, so that the area may be divided into an area in front of the door and another area.

  On the other hand, at the hall 17, at least one or more users including the user who has registered the hall call are waiting. The waiting number of the user is detected from the image of the camera 19 installed at the landing 17 and the detected waiting number is stored in the learning table 32b together with the boarding rate of each area of the car 12.

FIG. 7 shows an example of the learning table 32b.
In the example of FIG. 7, the learning result at a certain arbitrary floor is shown, but a similar learning table 32b is actually prepared for each floor. When the user registers the hall call, the learning table 32b corresponding to the registered floor is referred to.

  No. Data 1 indicates a state where the occupancy rate of the areas C and D on the rear side (back side) of the car 12 is high and the occupancy rate of the areas A and B on the front side (door side) is low. The waiting number at the landing 17 is one. For such a combination of the boarding rate and the number of people waiting, the presence or absence of the user's boarding is stored as a boarding history. The boarding history indicates whether or not the user has boarded in the learning result of α times (for example, 5 times) for the same combination. The boarding history “Yes” means that the user has boarded at least once in the learning results of the past α times for the same combination. The above α is the number of learning updates. In other words, if α = 5, the same combination is stored in the learning table 32b every five times, and if the user gets on at least once in the five learning results, the boarding history is “Yes”. .

  No. The data of No. 2 indicates a state in which the occupancy rate of the areas C and D on the rear side (back side) of the car 12 is low, and the occupancy rate of the areas A and B on the front side (door side) is high. There are two people waiting at the landing 17. "None" is stored as the boarding history for such a combination of the boarding rate and the number of people waiting. The boarding history “absent” means that the user has not boarded in the learning result α times for the same combination.

  The boarding determination unit 33 is a user waiting at the hall 17 based on the boarding rate of each area of the car 12 detected by the boarding rate detection unit 31a and the number of people waiting at the hall 17 detected by the waiting person detection unit 31b. Determines the possibility of getting on the car 12. Specifically, the boarding determination unit 33 searches the learning table 32b shown in FIG. 7 for a combination of the boarding rate of each area of the car 12 and the number of people waiting at the hall 17, and refers to the boarding history for the same combination. It is determined whether the user gets on the car 12 or not.

  The operation control unit 34 stops or passes the car 12 at the landing 17 (user's call registration floor) according to the determination result of the boarding determination unit 33.

  The notifying unit 35 notifies a user in the car 12 about boarding. Examples of the notification method include a method of displaying a message through the display device 25 and a method of making a voice announcement through the announcement device 26.

Next, the operation of the first embodiment will be described.
FIG. 8 is a flowchart illustrating the processing operation of the elevator control device 11 according to the first embodiment.

  Now, it is assumed that the user has registered a hall call by operating the hall call button 18 at the hall 17 on an arbitrary floor.

  As described above, the hall call includes information on the registered floor and the destination direction. Upon receiving the hall call information (Yes in step S101), the elevator control device 11 stores the registered floor and the destination direction included in the hall call in the call management table 32a (step S102). As shown in FIG. 4, for example, when the user registers an upward hall call at the hall on the second floor, the registered floor: "2F" and the destination direction: "upward" are stored in the call management table 32a.

  Here, the elevator control device 11 detects the occupancy rate of each area of the car 12 (step S103). As described with reference to FIG. 5, the elevator control device 11 divides the boarding space of the car 12 into a plurality of areas, and obtains the occupancy rate of the user for each of these areas. In detail, the image of the camera 13 installed in the car 12 is analyzed and the ratio of the user in each area of the car 12 is determined as the boarding rate.

  Further, the elevator control device 11 detects the number of people waiting at the hall 17 on the floor (call registration floor) where the user has registered the hall call (step S104). Specifically, the image of the camera 19 installed on the floor is analyzed and the number of users at the hall 17 is detected. When there are a plurality of users at the hall 17, it is assumed that the destination directions of these users are the same as the user who first called and registered.

  The timing for detecting the boarding rate and the number of waiting persons is based on the registration of the hall call. However, by the time the car 12 arrives at the call registration floor, the position and number of users in the car 12 may change, and the number of people waiting at the hall 17 may also change. . Therefore, when the car 12 approaches the call registration floor, that is, immediately before the call registration floor, it is preferable to detect the boarding rate and the number of people waiting.

  For example, if the call registration floor is “2F” and the car 12 is driving upward from the lowest floor, while the car 12 is moving from “1F” to “2F”, the boarding rate and waiting time It is preferable to detect the number of people.

  When the combination of the occupancy rate of each area of the car 12 and the number of people waiting in the hall 17 is obtained, the elevator control device 11 refers to the boarding history for the same combination in the learning table 32b, and The possibility of getting on the vehicle 12 is determined (step S105).

  In this case, for example, if the call registration floor is “2F”, the learning table 32b of “2F” is referred to. Here, the combination (current combination) of the boarding rate and the number of waiting persons obtained when the user registered the hall call is No. in the learning table 32b shown in FIG. If the combination is the same as the combination 1, it is determined that there is a high possibility that the user will get on the car 12 from the boarding history for the combination. On the other hand, when the current combination is No. in the learning table 32b shown in FIG. If the combination is the same as the combination 2, it is determined that the possibility that the user gets on the car 12 is low from the boarding history for the combination.

  When it is determined that there is a high possibility that the user gets on the car 12 (Yes in step S105), the elevator control device 11 stops the car 12 at the hall 17 on the call registration floor, and opens the user by opening the door. (Step S106).

  On the other hand, when it is determined that the possibility that the user gets on the car 12 is low (No in step S105), the elevator control device 11 controls the operation of the car 12 so as to pass through the call registration floor ( Step S107). At this time, the elevator control device 11 holds the information of the user's hall call in the call management table 32a, and controls the operation of the car 12 so as to respond to the hall call in the next lap (step S108). ).

  Even if it is determined in step S105 that the possibility of boarding is low, if there is a user who gets off at the hall 17, the elevator control device 11 stops the car 12 at the hall 17. At this time, when the user of the hall 17 gets on the car 12, it is assumed that the driver drives without holding the hall call. The fact that the user of the hall 17 has boarded the car 12 can be determined from the image of the camera 13 installed in the car 12.

  As described above, according to the first embodiment, the possibility that the user will board is determined from the relationship between the occupancy rate of each area of the car 12 and the number of people waiting at the hall 17, and the car is determined according to the determination result. 12 is stopped or passed at the call registration floor. Accordingly, when the combination is unlikely to allow the user to get on the vehicle, useless stopping of the car 12 can be avoided to prevent a decrease in operating efficiency.

  In the first embodiment, the boarding determination is performed for all floors. However, the boarding determination may be performed only for a specific floor. In general, a user often gets on the car 12 on the reference floor, so that when the car 12 responds to the hall call on the reference floor, the possibility of the user getting on in the above-described manner is determined. Then, the operation efficiency can be improved.

  In the first embodiment, the occupancy rate of each area is detected by using the camera 13 installed in the car 12. However, for example, the temperature of the floor of the car 12 is Alternatively, the riding rate of each area may be detected based on the temperature state. That is, since the temperature of the floor surface of the car 12 is generally low, a temperature difference occurs between a place where a user is present and a place where no user is present. By analyzing this temperature difference, it is possible to detect the occupancy rate for each area. Similarly, in the hall 17, the number of waiting persons may be detected by a method other than the camera 19, such as a temperature sensor.

(Second embodiment)
Next, a second embodiment will be described.
In the second embodiment, an elevator group management system having a plurality of cars is assumed.

  FIG. 9 is a diagram schematically showing a configuration of an elevator group management system according to the second embodiment, and shows a configuration in which three cars are group-managed. The number of cars is not limited to three, but may be two, or three or more.

  The group management control device 41 exists as a main control device, and controls the entire group management system such as assignment control for assigning a hall call registered at an arbitrary hall to one of the cars of each car. Further, the group management control device 41 has the same functions as the elevator control device 11 shown in FIG. 3 (image processing unit 31, storage unit 32, boarding determination unit 33, operation control Unit 34 and a notification unit 35).

  Under control of the group management control device 41, the car control devices 42a, 42b, and 42c control the operation of the cars 43a, 43b, and 43c corresponding to each car. Each of the cars 43a, 43b, 43c is provided with the camera 13 shown in FIG.

  On the other hand, hall call buttons 45a, 45b, 45c, and cameras 46a, 46b, 46c,... Are installed at the halls 44a, 44b, 44c,.

  The hall call buttons 45a, 45b, 45c... Are buttons for the user to register a hall call. The cameras 46a, 46b, 46c... Continuously photograph the state of the landings 44a, 44b, 44c. The cameras 46a, 46b, 46c... May be installed at any location as long as the entire landing can be photographed for each floor. The hall call buttons 45a, 45b, 45c ... and the cameras 46a, 46b, 46c ... are connected to the group management control device 41 via a transmission cable (not shown).

Next, the operation of the second embodiment will be described.
FIG. 10 is a flowchart illustrating the processing operation of the group management control device 41 according to the second embodiment.

  Now, for example, it is assumed that a user registers an upward hall call by pressing down the hall call button 45b in the hall 44b on the second floor. As described in the first embodiment, the hall call includes information on the registered floor and the destination direction.

  When receiving the hall call information (Yes in step S201), the group management control device 41 stores the registered floor and destination direction included in the hall call in the call management table 32a (step S202).

  The group management control device 41 assigns a hall call to any of the cars 43a, 43b, and 43c (step S203). More specifically, the group management control device 41 acquires operation state information (current position, operation direction, and the like) of each of the units via the unit control units 42a, 42b, and 42c. Then, the group management control device 41 assigns the call information to the car that can respond fastest among the cars 43a, 43b, and 43c based on the operation state information, and directs the car to the call registration floor. The car to which the hall call is assigned is called an "assigned car". For example, when the car 43a of the car A is determined as the assigned car, as shown in FIG. 11A, information on the assigned car is added to the call management table 32a.

  Here, the group management control device 41 detects the occupancy rate of each area of the car 43a determined as the assigned car (step S204). As in the first embodiment, the group management control device 41 divides the boarding space of the car 43a into a plurality of areas, and obtains the occupancy rate of the user for each of these areas. Specifically, an image of a camera (not shown) installed in the car 43a is analyzed, and a ratio of a user occupying each area of the car 43a is obtained as a boarding rate.

  It is assumed that the cars 43a, 43b, and 43c have the same boarding space, and the learning table 32b shown in FIG. 7 can be used in common by each machine.

  On the other hand, the group management control device 41 detects the number of people waiting at the hall 44b on the second floor where the user has registered the hall call (step S205). More specifically, the image of the camera 46b installed in the hall 44b is analyzed to detect the number of users in the hall 44b. When there are a plurality of users at the landing 44b, it is assumed that the destination direction (upward or downward) of these users is the same as the user who first called and registered.

  As described in the first embodiment, the timing for detecting the boarding rate and the number of people waiting is basically based on the registration of the hall call. However, before the car 43a arrives at the call registration floor, the position and number of users in the car 43a may change, and the number of people waiting at the hall 44b may also change. . Therefore, when the car 43a approaches the call registration floor, that is, immediately before the call registration floor, it is preferable to detect the boarding rate and the number of people waiting.

  When a combination of the occupancy rate of each area of the car 43a and the number of people waiting in the hall 44b is obtained, the group management control device 41 refers to the boarding history for the same combination in the learning table 32b, and The possibility of getting on the car 43a is determined (step S206).

  When it is determined that there is a high possibility that the user gets on the car 43a (Yes in step S206), the group management control device 41 stops the car 43a at the hall 44b on the registration floor and uses the door 43 by opening the door. The passenger is boarded (step S207).

  On the other hand, when it is determined that the possibility that the user gets on the car 43a is low (No in step S206), the group management control device 41 changes the allocation of the hall call of the user to another car (step S206). Step S208).

  More specifically, the group management control device 41 selects a car that can arrive at the call registration floor next to the currently assigned car as a change target based on the operating state information of each car. The group management control device 41 detects the occupancy rate of each area of the car selected as the change target. As a result of re-searching the learning table 32b based on the combination of the boarding rate of each area and the number of people waiting at the hall 44b, if the boarding history for the same combination is “Yes”, the user calls the car for that hall. Is reassigned.

  For example, when the call information of the user is changed to the car 43b of the car B, the contents of the call management table 32a are changed as shown in FIG.

  When the assignment is changed to the car 43b of the car B, the group management control device 41 stops the car 43b at the hall 44b on the call registration floor (step S208), opens the door, and allows the user to board (step S207). .

  If there is no other changeable car in step S208, as in the first embodiment, the car is passed through the call registration floor and the car 43a is moved in the next lap. A response is made (see steps S107 to S108 in FIG. 8).

  As described above, according to the second embodiment, in the group management system having a plurality of cars, the user is determined based on the relationship between the occupancy rate of each area of the car 43a determined as the assigned car and the number of people waiting in the hall 44b. Is determined to be less likely to get on, the hall call is reassigned to another car 43b that can be boarded. Thus, when the car 43b is made to respond, the user can get on the car 43b and drive efficiently.

(Third embodiment)
Next, a third embodiment will be described.
In general, if the users are crowded in front of the car door, the users often do not get on when they arrive at the landing, even if there is enough boarding space (see No. 2 in FIG. 7). Therefore, in the third embodiment, when the occupancy rate in front of the car door is high, the user in the car is notified to pack the car in the back, thereby creating an environment where the user can easily get on the car. Things.

  Hereinafter, the elevator system according to the first embodiment will be described as an example, but the same applies to the group management system according to the second embodiment.

  FIG. 12 is a flowchart illustrating a processing operation of the elevator control device 11 according to the third embodiment. The processing shown in this flowchart is executed after step S103 in the flowchart shown in FIG.

  That is, when the occupancy rate of each area of the car 12 is detected in step S103, the elevator control device 11 determines whether the occupancy rate of the areas A and B in front of the door is higher than the other areas C and D. Is determined (step S301). If the occupancy rate of the areas A and B in front of the door is higher than the other areas C and D (Yes in step S301), the elevator control device 11 notifies the user in the car 12 to pack the passengers deep. (Step S302).

  As a notification method, the notification is made by a message display through the display 25 provided in the car 12 or by a voice announcement through the announcement device 26 provided in the car 12. The notification may be made by both a message display and a voice announcement.

  FIG. 13 shows the riding state of each area of the car 12. FIG. 13A shows a state before notification, and FIG. 13B shows a state after notification. P in the figure schematically represents a two-dimensional image of the user taken from the ceiling with the camera 13.
