Description

  Embodiments described herein relate generally to an elevator group management system having a plurality of passenger cars.

  For example, in a building with a lot of traffic such as an office building, a plurality of cars are installed. When a hall call is registered at a landing on an arbitrary floor, one of the cars responds to the registration floor of the hall call. At this time, the car may arrive at the landing with some users on it. In such a case, even if there is a boarding space in the car, for example, if there are many users near the car door, the user waiting at the landing may call the next car without boarding. Many.

JP-A-4-41374

  As described above, depending on the boarding state of the car that has arrived at the boarding area, a user at the boarding may not board the car. However, the fact that the user does not get on the car called at the hall is a factor that significantly reduces the operation efficiency of the elevator. As a result, a large number of users stay at the hall, leading to an increase in waiting time.

  The problem to be solved by the present invention is to provide a group management system for elevators that increases the occupancy rate of the car, eliminates the staying state of users waiting at the landing, and shortens the waiting time.

  An elevator group management system according to an embodiment includes a plurality of cars, and one of the cars is assigned to a registration floor for the hall call based on a hall call registered on an arbitrary floor. To respond.

The elevator group management system allows a user who waits at the landing within the first range from the door of the car toward the landing when the car arrives at the registration floor for the landing call and opens the door. A door open state detecting means for detecting a staying state of a user who is riding in the vicinity of the door within a second range from the door in the car toward the back, and the car When the occupancy rate detecting means for detecting the occupancy rate of the vehicle and the door open time detecting means detect that the user is staying at the landing, the occupancy rate detecting means detects the occupancy rate detecting means. When it is determined that the user waiting at the landing based on the boarding rate at the time of arrival can board the car, whether the boarding is possible or not, and when the boarding judgment unit determines that the boarding is possible Opening detection means Thus, the notification control means for performing notification for promoting the boarding to the car in consideration of the staying state of the user who is riding near the door in the car detected, and the notification control means And an operation control means for closing the car and leaving the car toward the next destination floor when the occupancy rate of the car increases from the time of arrival.

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

(First embodiment)
FIG. 1 is a block diagram showing the configuration of an elevator group management system according to the first embodiment. In the example of FIG. 1, a configuration in which a plurality of elevators (here, A, B, and C No. 3 elevators) are group-managed is shown. The “elevator” referred to here basically indicates a “car”.

  In the figure, 11a to 11c are car control devices, and 12a to 12c are car rides. The car control devices 11a to 11c perform operation control of the corresponding car 12a to 12c. Specifically, control of a motor (winding machine) (not shown) and door opening / closing control are performed. These car control devices 11a to 11c are configured by a computer.

  Each of the cars 12a to 12c moves up and down in the hoistway by driving a motor (winding machine) (not shown). Load detectors 13a to 13c for detecting the load in the car compartment are respectively installed at the bottoms of the cars 12a to 12c. Load data detected by the load detectors 13a to 13c is transmitted to the group management control device 10 via the car control devices 11a to 11c, respectively.

  In addition, a car door 14a, an operation panel 15a, a speaker 16a, and the like are installed on the car 12a of the No. A machine. The car door 14a is openably and closably installed at the entrance of the front of the car 12a.

  The car door 14a is opened and closed by engaging with a landing door (not shown) when landing on the landing on each floor. The operation panel 15a is installed, for example, near the car door 14a in the car room. The operation panel 15a is provided with a number of operation buttons including a destination floor button, a door open button, a door close button, and the like. The speaker 16a is installed in the operation panel 15a. In the example of FIG. 1, the operation panel 15a and the speaker 16a are individually illustrated for convenience, but the speaker 16a is actually installed in the operation panel 15a. The speaker 16a is used when a voice announcement (see FIG. 6) or the like for promoting boarding is performed.

  Here, in the present embodiment, a monitoring camera 17a is installed in the vicinity of the car door 14a in the car 12a. The camera 17a can capture several frames of images per second, such as an in-vehicle camera. The camera 17a is installed toward the car door 14a. When the car 12a arrives at each floor and opens, the state of the landing on each floor is photographed including the state near the car door 14a ( (See FIG. 2).

  Each image (video) captured by the camera 17a is analyzed and processed in real time by the image processing device 18a. For example, the image processing device 18a extracts a person (here, an elevator user) from each image, and performs an analysis process such as tracking the movement of the person. Here, the image processing device 18a is provided independently of the car control device 11a, but the function of the image processing device 18a may be mounted in the car control device 11a.

  The same configuration applies to the car 12b car 12b and the car C car 12c.

  That is, a car door 14b, an operation panel 15b, a speaker 16b, and the like are installed on the car 12b of the No. B machine. A monitoring camera 17b is installed in the vicinity of the car door 14b in the car 12b. Further, an image processing device 18b for analyzing and processing each image (video) taken by the camera 17b in real time is provided independently of the camera 17b.

  A car door 14c, an operation panel 15c, a speaker 16c, and the like are installed in the car 12c of the No. C machine. A monitoring camera 17c is installed in the vicinity of the car door 14c in the car 12c. In addition, an image processing device 18c for analyzing and processing each image (video) taken by the camera 17c in real time is provided independently of the camera 17c.

  On the other hand, hall call buttons 21a, 21b, 21c,... For registering hall calls are installed in halls (elevator halls) on each floor. The hall call buttons 21 a, 21 b, 21 c... Are connected to the group management control device 10. The hall call buttons 21a, 21b, 21c... Are composed of an upward button and a downward button, and are configured to press the upward button or the downward button according to the destination direction of the user. It should be noted that the lowermost floor is composed only of an upward button and the uppermost floor is composed of only a downward button.

  “Place call” is a call signal 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. The “car call” is a call signal registered by operating a destination floor button provided in the car room, and includes information on the destination floor.

  Lanterns 22a, 22b, and 22c are installed at the landings on each floor. The lantern 22a notifies that the car 12a of Unit A has arrived at the landing by lighting. Similarly, the lantern 22b notifies that the car 12b of No. B has arrived at the landing by lighting. The lantern 22a notifies by lighting that the C car 12c has arrived at the landing. In the example of FIG. 1, the lanterns 22a, 22b, and 22c are only shown for the first floor, but are actually installed at the landings on each floor.

  The group management control device 10 is a device for performing group management control of the operation of the A to C machines. The group management control device 10 is configured by a computer in the same manner as the car control devices 11a to 11c. When a new hall call is generated, the group management control device 10 selects an optimum car from the cars 12a to 12c and assigns the hall call to the car.

  Specifically, the group management control device 10 determines the operation state (car position, operation direction, door open / closed state, etc.) of each car obtained from the car control devices 11a to 11c, the occurrence status of the landing call / car call, the load, etc. Based on the information, the most suitable car is selected from each car and a hall call assignment signal is output to that car. The hall call assignment signal is sent to the corresponding car control device among the car control devices 11a to 11c of each car. For example, when No. A is selected, a hall call assignment signal is sent to the car control device 11a of No. A. Thereby, the car control device 11a moves the car 12a to the registration floor of the hall call.

  FIG. 2 is a view for explaining the photographing range of the camera 17a installed in the car 12a of the No. A car and the functional configuration of the car control device 11a. Here, the explanation will be given by taking the Unit A as an example, but the same applies to the other Units B and C.

  In the car 12a, a camera 17a is installed facing the car door 14a. When the car 12a arrives at an arbitrary floor and opens, the camera 17a captures the state of the landing 20 and the state near the car door 14a in the car 12a. The photographing range at this time is adjusted to L1 + L2 (L1 >> L2). L <b> 1 is a shooting range on the landing side and is, for example, 5 m from the car door 14 a toward the landing 20. L2 is an imaging range on the car side, and is, for example, 50 cm from the car door 14a toward the back of the car. L1 and L2 are ranges in the depth direction, and the range in the width direction (direction orthogonal to the depth direction) is at least greater than the lateral width of the car 12a.

  Each image (video) photographed by the camera 17a is analyzed in real time by the image processing device 18a and sent to the car control device 11a together with the analysis result. On the other hand, load data indicating the loaded load of the car 12a is sent to the car control device 11a from a load detector 13a installed at the bottom of the car 12a.

  Here, as a function for realizing the present invention, the image processing device 18a includes a hall detection unit 31 and a boarding state detection unit 35. The car control device 11a includes a boarding rate detection unit 32, a boarding availability determination unit 33, a notification control unit 34, an operation control unit 36, and a dummy call registration unit 37.

  In the image processing apparatus 18a, the hall detection unit 31 detects the staying state of the user waiting at the hall 20 when the car 12a arrives at the registration floor of the hall call and opens. Specifically, the hall detection unit 31 exists in the shooting range L1 shown in FIG. 2 based on the analysis result of the captured image of the monitoring camera 17a installed in the car 12a toward the car door 14a. Detects user retention status.

  The boarding state detection unit 35 detects the staying state of a user who is in the vicinity of the car door 14a in the car 12a. Specifically, the hall detection unit 31 exists in the shooting range L2 shown in FIG. 2 based on the analysis result of the captured image of the monitoring camera 17a installed in the car 12a toward the car door 14a. Detects user retention status.

  In the car control device 11a, the boarding rate detector 32 detects the boarding rate of the car 12a. Specifically, the boarding rate detection unit 32 detects the boarding rate of the car 12a based on the load data of the load detector 13a installed in the car 12a.

  When the boarding detection unit 31 detects that the user is staying at the landing 20, the boarding availability determination unit 33 determines the boarding rate at the time of arrival of the car 12a detected by the boarding rate detection unit 32. Based on this, it is determined whether or not the user waiting at the landing 20 can board the car 12a.

  The notification control unit 34 makes a notification for promoting the boarding of the car 12a when it is determined by the boarding availability determination unit 33 that the boarding is possible. Specifically, the notification control unit 34 promotes the boarding of both the user at the hall 20 and the user on the car 12a through the speaker 16a installed in the car 12a. Make a voice announcement.

  The driving control unit 36 closes the car 12a and departs toward the next destination floor when the boarding rate of the car 12a increases after the notification by the notification control unit 34 from the time of arrival.

  The dummy call registration unit 37 determines whether the boarding is possible or not when the boarding determination unit 33 determines that boarding is not possible or when the state in which the user stays at the landing 20 after the notification by the notification control unit 34 does not decrease. Before the departure, a dummy call for registering the other car 12b or the car 12c to the registration floor is registered.

  Next, the operation of this system will be described.

  3 and 4 are flowcharts showing the processing operation of the car control device in the first embodiment.

  Now, for example, it is assumed that an upward hall call is registered at the hall 20 on the first floor, and the hall call is assigned to the car 12a of No. A. When the car 12a arrives at the first floor (the registration floor for the hall call) (Yes in step S11), the car control device 11a gets on the user who opens the car 12a and waits at the hall 20 (step S12). .

  Here, as described in FIG. 2, when the car 12a is opened at the landing 20, the state of the landing 20 and the car are monitored by the monitoring camera 17a installed in the vicinity of the car door 14a in the car 12a. The state near the car door 14a in 12a is photographed. Each image (video) photographed by the camera 17a is analyzed in real time by the image processing device 18a, and sent to the car control device 11a together with the analysis result. At this time, a load load of the car 12a is detected by a load detector 13a installed at the bottom of the car 12a, and load data indicating the load is sent to the car control device 11a.

  The car control device 11a first detects the staying state of the user waiting at the landing 20 based on the analysis result of the captured image of the landing 20 (step S13). In this case, if a person staying in the shooting range L1 shown in FIG. 2 can be detected, the person is regarded as a user who waits at the landing 20 (a user who intends to ride).

  In the present embodiment, the state where at least one user stays at the landing 20 is detected, but the number of users staying at the landing 20 using, for example, high-precision image analysis technology. It may be detected accurately including (waiting number of people).

  Subsequently, the car control device 11a detects the boarding rate at the time of arrival of the car 12a based on the load data (step S14). A boarding rate is calculated | required from the ratio of the rated load of the car 12a, and a loading load.

  For example, if the rated load of the car 12a is 1400kg (capacity 20 people) and the load detected when the car 12a arrives at the first floor (registered floor of the landing call) is 700kg, It is obtained as a rate of 50%. “Boarding rate 50%” means that there is 50% free space in the car 12a. Further, for example, “boarding rate 20%” means that there is 80% free space in the car 12a.

  Here, when there is no user at the landing 20, that is, when a user cannot be detected within the shooting range L1 (No in step S15), the car control device 11a opens the car 12a. After a predetermined time (for example, after 10 seconds), the door is closed and departed toward the next destination floor (step S24). The “next destination floor” is the registration floor of the car call or the landing call that is closest to the floor.

  On the other hand, when the state where the user stays in the photographing range L1 is detected (Yes in Step S15), the car control device 11a waits at the landing 20 based on the boarding rate of the car 12a. It is determined whether the person can get on the car 12a (step S16). In this case, if the boarding rate of the car 12a is equal to or less than a predetermined reference value (for example, 50%) for boarding availability determination, it is determined that the car 12a can be boarded.

  When it is determined that the vehicle can be boarded (Yes in step S16), the car control device 11a performs a notification for promoting the boarding of the car 12a (step S17). Specifically, for example, as shown in FIG. 6, a voice announcement such as “You can still get in. You are asked to cooperate with customers who are in the vicinity of the door.” From the speaker 16a. By such voice announcement, it is possible to ask the users in the car 12a for boarding cooperation. Further, since this voice announcement is also heard at the hall 20, it is possible to prompt the user of the hall 20 to get on.

  Note that the notification method is not limited to voice but may be display or both. In the case of notification by display, a display (not shown) is provided in the car 12a, and a message as shown in FIG. 6 is displayed on the display. Furthermore, a speaker or a display device may be provided at the hall 20 and the same notification may be given to the hall 20.

  Further, when the boarding promotion notification is made, the time for closing the car 12a is delayed by a certain time (for example, 5 seconds) from the normal time so that more users can get on the car 12a. good.

  After the boarding promotion notification, the car control device 11a determines whether or not the boarding rate of the car 12a has increased from the time of arrival (step S18). If the boarding rate of the car 12a is higher than that at the time of arrival, it can be regarded that the user waiting at the hall 20 has boarded the car 12a. Even if the user gets on the car 12a, the boarding rate may not increase if there is a user who gets off the car 12a. That is, when the number of users getting off is larger than the number of passengers, the boarding rate of the car 12a does not increase. Such a case is dealt with in step S19 described later.

  When the occupancy rate of the car 12a increases (Yes in step S18), the car control device 11a closes the car 12a after a predetermined time and starts to the next destination floor (step S24).

  In addition, when the boarding rate of the car 12a does not increase even after the boarding promotion notification is made (No in step S18), the car control device 11a determines the user's based on the analysis result of the captured image of the hall 20. A staying state is detected (step S19). In this case, the proportion of users in the photographing range L1 shown in FIG. 2 is detected, and it is considered that the larger the proportion of the users, the larger the number of users staying, that is, the larger the number of waiting people. It should be noted that the number of users staying at the hall 20 (waiting number of people) is accurately detected using high-precision image analysis technology, and it is determined whether or not the number of users is greater than or equal to a predetermined number (for example, two). That's fine.

  If the staying state of the user is smaller than the arrival time of the car 12a (Yes in step S20), the user waiting at the landing 20 has boarded the car 12a. In this case, the car control device 11a does not register a dummy call to be described later (step S21), closes the car 12a after a predetermined time, and departs toward the next destination floor (step S24).

  On the other hand, if the staying state of the user is the same as the arrival time of the car 12a or increases from the arrival time (No in Step S20), the user remains on the landing 20. In this case, the car control device 11a registers a dummy call before the departure of the car 12a (step S22).

  The “dummy call” is a hall call that is automatically registered on behalf of the user, and has information on the registered floor and the destination direction in the same way as a normal hall call. In this case, a dummy call having the same registration floor (first floor) and destination direction (upward) information as the hall call currently being answered by the car 12a is registered.

  The dummy call information is sent from the car control device 11a to the group management control device 10. The group management control device 10 receives this dummy call information as newly registered hall call information, selects the most suitable car from other cars (B machine, C machine) other than the A machine, Let the car of that unit respond to the registration floor. Thereby, since the user who did not get on the car 12a of No. A can be carried on the car of another car early and carried, the waiting time of the user can be shortened.

  In the following description, it is assumed that Unit B has been selected by registration of a dummy call.

  The group management control device 10 outputs the dummy call assignment signal to the car control device 11b of the B car, and the car 12b of the B car responds to the registration floor. When the car 12b approaches the registration floor, the car control device 11b of the B car lights up the lantern 22b for the B car installed on the registration floor and notifies the arrival of the car 12b (step S23). .

  Here, when the arrival of the car 12b is notified, if the lantern 22b is turned on too early, the user at the hall 20 does not get on the car 12a of the car A that has already arrived. There is a possibility of getting on 12b. This is called “distributed riding” and causes a reduction in the boarding rate per vehicle. That is, dummy call registration can reduce the waiting time of the user, but on the other hand, it may induce distributed boarding. Therefore, it is preferable to notify the arrival of the other unit by a dummy call as soon as possible before the arrival of the other unit. The same applies when the arrival sound is generated in conjunction with the lighting of the lantern.

  Further, as shown in FIG. 5, the timing for registering the dummy call may be delayed in order to get as many users as possible on the car 12a of the No. A car that has already arrived.

  FIG. 5 is a flowchart showing a dummy call registration process.

  In step S22, when registering a dummy call, the car control device 11a first obtains the number of passengers who can get on the car 12a of the car A that has already arrived (step S31). Specifically, the car control device 11a obtains the number of passengers Pb of the current user based on the loaded load of the car 12a obtained from the load detector 13a, and the number of passengers that can be boarded from the difference between the rated number Pa and the number of passengers Pb. Pc is calculated.

For example, it is assumed that the loading load of the car 12a is 1000 kg. When the average body weight (including the weight of luggage) of one user is 70 kg, the number of passengers Pb is obtained as follows.
Pb = 1000 / 70≈14
If the rated number of people Pa = 20, the number of people Pc that can be boarded is obtained as follows.
Pc = Pa-Pb = 6
When the number of passengers Pc that can be boarded is obtained, the car control device 11a sets the dummy call registration timing step by step according to the number of passengers Pc that can be boarded (step S32). In this case, the dummy call registration timing is delayed as the number of passengers Pc increases. Specifically, for example, with reference to Pc = 2, a time T for registering a dummy call is set under the following conditions.

Pc = 2 or less: T = t0 (register dummy call immediately)
Pc = 3-5 people: T = t1 (5 seconds behind t0)
Pc = 6 or more: T = t2 (10 seconds behind t0)
When the set time T is reached (Yes in step S33), the car control device 11a registers a dummy call (step S34). This dummy call includes the same information on the registered floor (first floor) and destination direction (upward) as the hall call currently being answered by the car 12a.

  In this way, as the number of passengers who can board the car 12a increases (the empty space becomes larger), the dummy call registration timing is delayed so that the user can avoid getting on different cars and arrive first. It is possible to start after putting as many users as possible in the car 12a of the A machine.

  As described above, according to the first embodiment, the boarding state is determined based on the relationship between the staying state of the user waiting at the landing and the boarding rate of the car, and when the boarding is possible, the boarding promotion notification is given. You can drive with a higher car occupancy rate. Thereby, it can be expected that the number of users waiting at the landing on each floor is reduced, and as a result, the waiting time of the users can be shortened.

  Furthermore, if it is determined that there is a user who has not boarded the car that has arrived at the boarding area, a dummy call is registered before the departure of the car so that the other machine can respond quickly and the user The waiting time can be shortened.

(Second Embodiment)
Next, a second embodiment will be described.

  In the said 1st Embodiment, it was set as the structure which performs boarding promotion notification irrespective of the state of the user who has boarded in the passenger car. However, in general, there are many users near the doors in the car, so that users at the hall often hesitate. Moreover, even if the vicinity of the door in the car is vacant, performing the boarding promotion notification as shown in FIG. 6 may cause the user in the car to feel uncomfortable. Therefore, in the second embodiment, it is assumed that the boarding promotion notification is made according to the state of the user who is in the car.

  The processing operation of the second embodiment will be described below. Since the basic processing flow is the same as that of the first embodiment, only different parts will be described here.

  FIG. 7 is a flowchart showing the processing operation of the car control device according to the second embodiment.

  Now, for example, it is assumed that an upward hall call is registered at the hall 20 on the first floor, and the hall call is assigned to the car 12a of No. A.

  As in the first embodiment, when the car 12a arrives on the first floor (registered floor of the hall call), it is determined whether or not the car can be boarded based on the relationship between the staying state of the users waiting at the hall and the boarding rate of the car. (Steps S11 to S16).

  Here, in the second embodiment, when it is determined that the vehicle can be boarded (Yes in step S16), the car control device 11a gets in the vicinity of the car door 14a based on the analysis result of the captured image of the car 12a. The staying state of the user who is staying is detected (step A11). In this case, the proportion of users in the photographing range L2 shown in FIG. 2 is detected, and the larger the proportion of the users, the larger the number of users staying, that is, the greater the number of uses near the car door 14a The person is staying. It should be noted that the number of passengers (the number of passengers) staying in the vicinity of the car door 14a is accurately detected using a highly accurate image analysis technique, and whether or not a predetermined number (for example, two persons) or more are present in the vicinity of the car door 14a. It may be determined.

  When a large number of users are staying near the car door 14a, that is, when a large number of users are detected in the photographing range L2 (Yes in step A11), the car control device 11a is shown in FIG. A boarding promotion notification as shown is performed (step S17).

  Further, when there are not many users in the vicinity of the car door 14a, that is, when many users are not detected within the photographing range L2 (No in Step A11), the car control device 11a notifies the boarding promotion. Without changing, the change in the boarding rate of the car 12a is monitored (step S18). When the occupancy rate of the car 12a increases from the time of arrival (Yes in step S18), the car control device 11a closes the car 12a after a predetermined time and leaves for the next destination floor (step). S24).

  As described above, according to the second embodiment, when a large number of users stay in the vicinity of the door in the car, the boarding promotion notification is given, so that the boarding can be reduced because of the boarding state in the car. It is possible to get on boarding passengers actively. In this case, when there is an empty space near the door in the car, the boarding promotion notification is not performed, so that the user in the car does not feel uncomfortable.

(Third embodiment)
Next, a third embodiment will be described.

  If the car occupancy rate is increased by a boarding promotion notification, the car may depart when the car is almost full. When responding to a hall call on another floor in a state where it is almost full, the users waiting at the hall on that floor cannot be picked up, and the operation efficiency is significantly reduced. Therefore, in the third embodiment, when the car departs in a state where the car is almost full, it passes through a floor where a car call is not registered (hereinafter referred to as a car call unregistered floor), and another car on that floor. To respond.

  The processing operation of the third embodiment will be described below. Since the basic processing flow is the same as that of the first embodiment, only different parts will be described here.

  FIG. 8 is a flowchart showing the processing operation of the car control device according to the third embodiment.

  Now, for example, it is assumed that an upward hall call is registered at the hall 20 on the first floor, and the hall call is assigned to the car 12a of No. A.

  As in the first embodiment, when the car 12a arrives on the first floor (registered floor of the hall call), it is determined whether or not the car can be boarded based on the relationship between the staying state of the users waiting at the hall and the boarding rate of the car. (Steps S11 to S16). When boarding is possible, a boarding promotion notification as shown in FIG. 2 is made, and it is determined whether or not the boarding rate of the car 12a has increased from the time of arrival (step S18).

  Here, in the third embodiment, when the boarding rate of the car 12a is increased from the arrival time (Yes in Step S18), the car control device 11a sets the boarding rate before departure of the car 12a in advance. It is determined whether or not a full reference value (for example, 80%) for fullness determination is exceeded (step B11). When the boarding rate before departure of the car 12a does not exceed the reference value for full determination (No in Step B11), the car control device 11a closes the car 12a after a predetermined time, and Departure toward the destination floor (step S24).

  On the other hand, when the boarding rate before departure of the car 12a exceeds the reference value for fullness determination (Yes in step B11), the car control device 11a controls the operation so as to pass the car call unregistered floor. (Step B12). Specifically, if the registered floor of the hall call to which the car 12a responds next is the car call unregistered floor (the floor where the user does not get off), the car control device 11a cancels the hall call. For example, it is assumed that an upward hall call is assigned to the car 12a on the second floor. At this time, if the car call on the second floor is not registered in the car 12a that departs upward from the first floor, the hall call is canceled and the car passes through the second floor.

  At that time, the car control device 11a registers a dummy call with respect to the car call unregistered floor to be passed, and makes other cars respond (step B13). As described above, the “dummy call” is a hall call that is automatically registered on behalf of the user, and has information on the registration floor and the destination direction in the same way as a normal hall call. In this case, a dummy call having information on the car call unregistered floor (second floor) and the destination direction (upward direction) that is to be passed is registered.

  The dummy call information is sent from the car control device 11a to the group management control device 10. The group management control device 10 receives this dummy call information as newly registered hall call information, selects the most suitable car from other cars (B machine, C machine) other than the A machine, Let the car of that unit respond to the registration floor. Thereby, since the car of another car can be made to respond early to the floor where the car 12a of car A does not stop, the waiting time of the user can be shortened.

  Now, assuming that Unit B is selected by registration of a dummy call, when the car 12b approaches the registration floor, the car control device 11b of the Unit B uses the lantern 22b for Unit B installed on the registration floor. Illuminates to notify arrival of the car 12b (step B14).

  As described above, according to the third embodiment, when the car departs in a state where the car is almost full, operation control is performed so as to pass through the unregistered floor of the car call. Can be avoided. At that time, the waiting time of the user waiting at the landing on the floor can be shortened by registering a dummy call and making other units respond.

  According to at least one of the embodiments described above, it is possible to provide an elevator group management system that increases the occupancy rate of a car, eliminates the staying state of users waiting at the landing, and shortens the waiting time. it can.

  In each of the above embodiments, an image captured by a single camera installed in the vicinity of the door in the car is analyzed to detect the state of the landing and the state in the vicinity of the door in the car. Two cameras may be installed in the car, and the image taken by each camera may be analyzed to detect the state of the landing and the state near the door in the car.

  In short, several embodiments of the present invention have been described, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
