Description

  The present invention relates to a group management elevator apparatus that performs destination floor registration at an elevator landing, and more particularly to a group management elevator apparatus that allows a group user to register a destination floor (depot destination call) at an elevator landing.

  In large-scale high-rise buildings with many elevator users, multiple elevators are installed in the same building, and group management control is performed on these multiple elevators to improve overall operation efficiency. ing. A group management elevator apparatus that performs such group management control is known, for example, from Japanese translation of PCT publication No. 2007-518652 (Patent Document 1).

  In the group management elevator apparatus described in Patent Document 1, the destination floor and the number of people in the group (number of users) before boarding so that the user can comfortably use the elevator in a group of a plurality of people. Can be registered. That is, when the representative of the group inputs the destination floor and the number of users from the destination operation panel of the landing, the group management control device assigns a passenger car having a space for the number of users to the landing destination call. I am doing so.

  However, in the group management elevator device described in Patent Document 1, when a user uses an elevator in a group, the representative of the group must confirm the number of users before inputting the number of users on the destination operation panel. Had to be done. For this reason, there has been a problem that this confirmation work is troublesome and inconvenient. Also, if a large value is entered as the number of users, the user has to wait at the landing until there is enough space in the car for the number of users. In such a case, it is necessary to make room for the number of passengers in the assigned car, and there is a problem that the operation efficiency is remarkably lowered.

  In order to solve such a problem, in the republished patent WO2009 / 141900 (Patent Document 2), a destination operation panel in which a user registers a destination floor before boarding, and a user uses an elevator in a group. A group boarding registration device for registering the effect is installed at the elevator platform, and the number of users when the user uses the elevator in a group is stored in the user number storage unit in advance. If the destination floor is registered on the destination operation panel together with the group use registration on the group boarding registration device, the car assigned to the landing destination call is based on the number of users stored in the user number storage unit. To make decisions. According to this, even when a group of a plurality of people uses an elevator, it is said that it is excellent in convenience and can prevent a decrease in operation efficiency.

By the way, in this type of group management elevator device as described in Patent Document 1, when performing destination floor registration in a group, the configuration is such that the user inputs the number of people in the group using the landing destination floor registration device. It is assumed that the representative of the group inadvertently inputs the wrong number of persons or intentionally inputs a number of persons different from the number of persons in the group. In this way, when the number of group users is different from the actual number, it becomes difficult to assign an appropriate elevator and the operation efficiency is reduced. Since the elevator car has only a small number of passengers, all of the group users cannot ride and some of the users are left behind. On the contrary, when the number of people in the group is input more than the actual number, the assigned elevator car is vacant, so the number of passengers is reduced and the operation efficiency is lowered. Furthermore, a situation occurs in which other users cannot get on, which also causes a decrease in operation efficiency. As described above, since the number of registered group users becomes inaccurate, it is impossible to assign an appropriate elevator car, and there is a problem that the operation efficiency of the elevator apparatus is lowered.

  An object of the present invention is to provide a new group management elevator apparatus capable of appropriately assigning elevators according to the number of users in an actual group.

  The feature of the present invention is that when the landing destination floor registration device is operated, the number of group users in the vicinity of the landing destination floor registration device is detected by the user number detection means, and the detected number of group users is detected. Correspondingly, there is an elevator assignment.

  According to the present invention, since the actual number of group users is detected by the user number detection means and the elevators are assigned, the elevators can be appropriately assigned, and the operation efficiency can be improved. It becomes like this.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments, and various modifications and application examples are included in the technical concept of the present invention. Is also included in the range.

  FIG. 1 is a perspective view showing a landing on a certain floor of a group management elevator apparatus to which the present invention is applied, and a building such as a high-rise building is provided with a plurality of elevators 1A to 1N. The group management elevator apparatus provides a more efficient operation service to the user by handling a plurality of elevators 1A to 1N as one group.

  Specifically, multiple elevator units are managed as a group, the optimal car is selected for a newly registered landing call on a certain floor, and the previous landing call is assigned to that car Is to implement.

  The group management elevator device according to the present embodiment is a destination floor registration type group management system, which is a group management in which a destination floor is registered in advance at a landing. For this reason, since a user's destination floor is known at the time of call registration, a suitable car can be assigned to each destination floor.

  And, in the landing, a landing destination floor registration device that is arranged on the wall surface of the landing and used to register the destination floor, or a centralized arrangement type that is arranged in another position and used to register the destination floor A landing destination floor registration device 2 is arranged. In this embodiment, a centrally arranged landing destination floor registration device 2 is used.

  Furthermore, it has the arrival light 3 which notifies which elevator arrives according to a landing call according to direction, and the output guide apparatus 4 arrange | positioned for every elevator. As the output guide device 4, any of a display device, a voice notification device, and a composite device combining them is used.

  As shown in FIG. 2, the landing destination floor registration device 2 includes an output unit 6 that performs display output or audio output, and a group that is pressed by the user when registering the destination floor for the purpose of group use. The button 7, a disabled person button 8 that is pressed when the disabled person registers the destination floor, and a plurality of numeric buttons 9 that are pressed to specify the number of groups and the destination floor.

  Then, when the group user inputs the destination floor and the number of people, one of the assigned elevators 1A to 1N is displayed on the output unit 6 with numbers or notified by voice. The group user accordingly moves in front of the assigned elevator and waits for the car to arrive.

  Next, a schematic configuration of a main part of a specific group management control device 30 will be described with reference to FIG. As described above, the landing destination floor registration device 2 is connected to the receiving unit 10 of the group management control device 30, and input / output from the output unit 6, the group button 7, the handicapped button 8, and the numeric buttons 9 that are input / output units. The signal is configured to be captured through the receiving unit 10 of the group management control device 30.

  In the group management control device 30, based on the destination floor registration information and the number of people information fetched from the landing destination floor registration device 2, the elevator unit assignment function unit 13 is most suitable for elevator assignment processing, arrival lamp 3, and output guidance. Control such as notification processing in the apparatus 4 is performed.

  In addition, when the group management control device 30 receives a signal indicating that the group button 7 has been pressed through the receiving unit 10, the group management control device 30 has a plurality of group users who operate the landing destination floor registration device 2. The group handling processing function unit 11 that performs processing corresponding to the group user and the user who is operating when the signal indicating that the handicapped button 8 is pressed is received through the receiving unit 10 And a handicapped person corresponding processing function unit 12 that performs processing corresponding to the handicapped person by determining that the person is a handicapped person.

  Further, the group management control device 30 receives signals from the group correspondence processing function unit 11 and the handicapped person correspondence processing function unit 12 and assigns the most suitable elevator number corresponding to these processing function units 11 and 12. Elevator output assigning function unit 13 for performing the operation, landing arrival light 3 for the elevator assigned by the elevator assignment functioning unit 13, output guide device 4, and landing output for controlling the output unit 6 of the landing destination floor registration device 2 A control function unit 14, a storage function unit 15 that stores a control program and temporarily stores learning data and input information, and a control function unit 16 that controls each function unit described above by the control program of the storage function unit 15. It has.

  Such a group management control device 30 manages a plurality of elevators as a group, selects the most suitable car for a newly registered landing call on a certain floor, and places the previous landing on that car. When the process of assigning calls is performed, this assignment signal is sent to the elevator control panel 21 and the corresponding elevator car is operated on the basis of this.

  The present embodiment is characterized in that a new function described below is added to the group correspondence processing function unit 11 described above. In the present embodiment, the group correspondence processing function unit 11 uses an image of a video camera 31 (hereinafter simply referred to as a camera) that is an imaging unit that uses an imaging device that constitutes a user number detection unit installed at a landing. Estimate the actual number of group users. The camera 31 can be a camera provided on the ceiling of the landing so as to capture an image in the vicinity of the landing destination floor registration device 2 or a camera provided on the landing destination floor registration device 2 itself. In the present embodiment, the camera 31 provided in the landing destination floor registration device 2 is used, whereby an image of the vicinity of the landing destination floor registration device 2 can be taken.

  The estimated group user's actual group number is compared with a predetermined number of people determination threshold, and information on whether the actual group number exceeds the predetermined number of people determination threshold is sent to the elevator unit assignment function unit 13, When the number of group users of the group user exceeds a predetermined threshold value of the predetermined number of people by the elevator unit assigning function unit 13, the elevator number dedicated to the group is assigned, and the group number of the group user exceeds the threshold value of the predetermined number of people. If there is not, an elevator unit having a vacant number of group users is allocated.

  In order to execute such a function, the group correspondence processing unit 11 inputs an image of the camera 31 to estimate an actual group number, and compares it with a determination threshold value described later, a determination threshold value setting function. Unit 18 and a determination threshold adjustment learning function unit 19.

  When the receiving unit 10 determines that the user is a group user from the signal input from the group button 7, the temporary number of the group is then determined from the signal input from the number button 9. Input to the unit 17. The group number determination function unit 17 estimates the number of group users by analyzing the image from the camera 31, and compares it with the temporary number of group users input from the signal input from the numeric buttons 9. Has the function to perform.

  If the estimated number of persons from the image analysis of the camera 31 matches the provisional number of persons input from the number buttons 9, this number of persons is determined as the actual number of group users. On the other hand, if the estimated number of persons from the image analysis of the camera 31 and the temporary number of persons input from the number buttons 9 do not match, it is determined that the temporary number of persons input from the number buttons 9 is incorrect. The camera 31 has a function of determining the estimated number of persons based on the image analysis of the camera 31 or a predetermined number of persons as the actual number of group users.

  Further, when the receiving unit 10 determines that the user is disabled from the signal input from the disabled button 8, a signal indicating that the user is disabled is input to the disabled handling function unit 12. In addition, since this invention is invention regarding a group user, description about utilization of a disabled person is abbreviate | omitted.

  Then, the determination threshold value from the determination threshold value setting function unit 18 that stores a determination threshold value that is the number of group members serving as a determination reference is input to the group number determination function unit 17. The group number determination function unit 17 has a function of comparing and determining the determination threshold value and the actual number of group users. The determination threshold value may be a fixed number of people, or may be changed so as to be an appropriate number of people depending on the operation status. In this embodiment, a determination threshold adjustment learning function unit 19 is provided, and the determination threshold can be adjusted by the determination threshold adjustment learning function unit 19.

  The determination threshold adjustment learning unit 19 can adjust the determination threshold according to various parameters related to the operation of the car. Typically, the determination threshold adjustment learning unit 19 increases the determination threshold when there are many users because it is used by group users. It can be adjusted in the direction you want. The reason for this is that the determination threshold is increased from the viewpoint that there are many cases that the user is a group user, and since they are acquainted with each other, there is no problem even if they enter a little more.

  In addition, as the number of group users increases and the number of elevators dedicated to the group increases, there is a possibility that the operation efficiency will decrease accordingly. In this case as well, it is possible to raise the determination threshold value so that more passengers can be put on the elevator dedicated to the group and the number of elevators dedicated to other groups can be reduced. In this case as well, the determination threshold value can be increased from the viewpoint that there are many cases that the user is a group user and that there is no problem even if a small number of people are boarded. Furthermore, since it is possible to estimate the number of group users based on past history, for example, the history of the number of users, the day of the week, the history of changes in the number of users for each hour, etc., the determination threshold is adjusted from this history information. It is also possible.

  Thus, by adjusting the determination threshold value, the number of elevators dedicated to the group can be flexibly changed, and as a result, the operation efficiency of the group management elevator device can be increased.

  As described above, when the actual number of group users is determined, this number is compared with a predetermined determination threshold value in the group number determination function unit 17, and if the input number is greater than the determination threshold value, the elevator number is assigned. When the function unit 13 assigns an elevator dedicated to the group and the number of persons entered is smaller than the determination threshold, the elevator assignment function unit 13 causes a general elevator that has space for the number of group users (in the case of a dedicated elevator) Is not assigned).

  When this assignment is performed, this assignment information is sent to the landing output control function unit 14 and the result is notified from the output unit 6 of the landing destination floor registration device 2. And a group user should just get on the elevator number allocated based on this alerting | reporting result.

  Here, the passenger number detection means included in the group number determination function unit 17 obtains an image from the camera 31 installed in the landing destination floor registration device 2, and estimates the number of groups by analyzing this image. However, it is also possible to estimate the number of group users from the image of the camera that is shooting the landing, and measurement signals from various sensors such as an infrared sensor and a distance measuring sensor.

  Next, a specific elevator unit assignment processing operation of the group management control device 30 will be described with reference to the flowcharts shown in FIGS. 4A and 4B.

<< Step S40 >>
First, the group management control device 30 monitors the input status of the landing destination floor registration device 2, and in step S40, when detecting the input signal when the group button 7 of the landing destination floor registration device 2 is pressed, It is determined that the destination floor registration by the user is performed, and the landing destination floor registration process after step 41 is executed. On the other hand, if it is determined in step S40 that the group button 7 has not been pressed, the process returns to the original state and the input of the group button 7 is monitored.

  Here, since the landing destination floor registration device 2 can be operated not only by a group user but also by an individual user, if there is no input of the group button 7 and there is input of the number button 9 first, Therefore, the process proceeds to another step, and the allocation process is executed for the elevators having vacancy. Thus, in step S40, it is determined whether the user is a group user or an individual user depending on whether or not the group button 7 is input.

<< Step S41 >>
Next, when it is determined in step S40 that the group button 7 has been pressed, the process proceeds to step S41. In step S41, it is determined whether or not there has been an input using the numeric buttons 9 of the landing destination floor registration device 2. When the temporary number of group users is input by the numeric button 2, the process proceeds to step S42. When the number of group users by the numeric button 9 is not input, the process returns to step S41 and the input of the number of persons by the numeric button 9 is monitored. . Here, since the number of group users is input by the numeric buttons 9, the representative of the group may inadvertently input the wrong number of persons or intentionally input a different number of persons from the number of groups. There is a risk that it will happen. For this reason, the input of the number of people by the number buttons 9 is handled as a temporary number of people.

<< Step S42 >>
When the tentative number of group users is input in step S41, it is assumed that registration of the destination floor of the group user has occurred, and in step S42, the number of groups is estimated by image analysis of the camera 31. The analysis using the camera image specifies that the person is a person by extracting the feature amount of the person, and estimates the number of persons by the sum of the person and the specified data. Such feature amount extraction is well known and a known method can be used. This step S42 may be performed between step S40 and step S41 after the group button 7 is input.

<< Step S43 >>
When the number of groups in the group is estimated by image analysis of the camera 31 in step S42, in step S43, the temporary number of group users and the number of groups estimated by image analysis are checked using the numeric buttons 7. This collation is determined based on whether or not the estimated number of people matches the number of people, and if they match, the number of people is determined as a true group and the process proceeds to step S47. This coincidence determination is based on the determination that a slight difference in the number of persons (about 1 to 2 persons) is the same, and the difference in the number of persons is appropriately determined from the specifications of the system. On the other hand, if the number of persons estimated in step S43 does not match the number of persons estimated, the process proceeds to step S44 to tentatively determine the number of persons because the number of persons is not true.

  Here, when the estimated number of persons coincide with each other and are determined as the true group number in step S43, floor data, and preferably data such as day of the week, time, etc. are given, and the true number of persons is determined. It can be stored as a group user on the floor. As a result, the statistical number of users of the group users on the floor can be grasped and utilized for various statistical processes.

<< Step S44 >>
In step 44, it is determined whether the number of persons estimated by image analysis is larger or smaller than a preset upper limit number of persons (hereinafter referred to as an upper limit number of persons). The upper limit number of people can use the number of people obtained by a statistical method for the floor.

  For example, an upper limit number of people for each destination floor on a certain floor can be used, and further, an upper limit number of people for each destination floor can be used based on the day of the week, time, etc. on a certain floor. Thus, by using the predetermined upper limit human figure, it becomes possible to allocate elevators up to at least the upper limit human figure. If the number of persons estimated in step S44 is smaller than the upper limit human figure, the process proceeds to step S45, and if the estimated number of persons is larger than the upper limit human figure, the process proceeds to step S46.

<< Step S45 >>, << Step S46 >>
If it is determined in step S44 that the estimated number of persons is smaller than the upper limit number of persons, in step 45, the number of persons estimated from the camera image is determined as the actual number of persons. If it is determined in step S44 that the estimated number of persons is larger than the upper limit number of persons, in step 46, the upper limit number of persons is determined as the actual number of persons.

  Note that step S45 may be directly executed without executing steps S44 and S46, and the number of persons estimated from the camera image may be determined as the actual number of persons.

<< Step S47 >>
When the actual number of group users is determined in steps S43, S45, and S46, a determination threshold that is a predetermined number of group users and a group determined in steps S43, S45, and S46 are determined in step S47. The number of users is compared and determined. The technical significance of providing this step S47 is as follows. For example, it is easy to understand when a group customer moves to the same floor at the same time.

  In other words, if the number of group users is larger than the judgment threshold, such as group customers, it is better to allocate a dedicated elevator and move to the destination registration floor at a time from the viewpoint of operation efficiency. Is based on the reason. Here, the determination threshold value used in this step S47 is determined by the capacity of the elevator car, and when there is a large capacity, the determination threshold value is appropriately determined accordingly. Furthermore, as described above, the determination threshold value can be appropriately adjusted by learning control.

  On the other hand, if the number of group users is smaller than the determination threshold in step S47, there is no need to bother to assign a dedicated elevator and it can be handled in the same way as an individual user. There is an elevator that is assigned. Therefore, if the actual number of group users is larger than the determination threshold in step S47, the process proceeds to step S48, and if the actual number of group users is smaller than the determination threshold, the process proceeds to step S49.

<< Step S48 >>
If it is determined in step S47 that the actual number of group users is greater than the determination threshold value, a process of assigning a dedicated elevator to serve only to this group user is performed. By assigning a dedicated elevator to a large number of group users in this way, it becomes possible to carry many group users to the same destination registration floor at once, and it is possible to improve the operation efficiency of the elevator Become.

  When there are a large number of groups, it is difficult to quickly assign elevators with enough space that all group users can board with the conventional group management method, and group users are dispersed and board multiple elevators. Was needed.

  On the other hand, in this embodiment, a large number of group users can be assigned to the same destination registration floor at one time by assigning a dedicated elevator to improve the operation efficiency and satisfy the group users. Can be given.

  In addition, when a group user moves to the destination registration floor at once, the desire to arrive at the registration floor as soon as seen from the group user is satisfied, so that the satisfaction regarding the comfort of the group user can be obtained. become.

  Here, the number of elevators dedicated to the group may be increased or decreased based on the current usage situation and the predicted usage situation in the future. For example, when there are many groups with a large number of people, the group users can be moved quickly by increasing the number of dedicated elevators.

  In addition, when the time period when there are many groups such as lunch time has passed, the group users will return to the workplace, so reduce the number of elevators dedicated to the group and increase the number of general elevators. Elevator units can be quickly allocated to individual users and small group users.

<< Step S49 >>
On the other hand, if it is determined in step S47 that the actual number of group users is smaller than the determination threshold, a process of assigning an elevator having a space in which the number of group users can board is performed. In this way, since the group users with a small number of people can quickly assign elevators that can be boarded, it is possible to improve the operation efficiency of the elevators.

  In addition, since a large number of group users do not board, there is less need for individual users to get out of the car or move to pass through group users, and there is a sense of satisfaction regarding the comfort of individual users. It will be obtained.

  In this way, as shown in step S48 and step S49, depending on the number of group users, the process of assigning a dedicated elevator or assigning a normal elevator that can be boarded is performed. As a result, it is possible to improve the service efficiency and improve the serviceability for individual users and group users.

<< Step S50 >>
When the elevator car is assigned in steps S48 and S49, it is determined in step S50 whether or not the destination floor is input by the floor button of the destination floor. This destination floor is input by the numeric buttons 9 of the landing destination floor registration device 2. When the destination floor is input, the process proceeds to step S51. When the destination floor is not input, the process returns to step S50 and the destination floor is input. Will be monitored.

<< Step S51 >>
This step S51 is a process for actually allocating elevators allocated according to the number of group users determined in steps S48 and S49. This makes it possible to quickly call the elevator that is the target of the currently operated elevator to the floor where the group user is staying.

<< Step S52 >>
When the assignment of elevators is completed in step S51, the following process is performed on the result of the assignment process in step S52. That is, information regarding the assigned elevator number is transmitted to the output unit 6 of the landing destination floor registration device 2 to notify the group user who is performing the destination floor registration operation. The group user moves in front of the elevator assigned in accordance with this and waits for the arrival of the car.

  Further, in step S52, a command signal is transmitted to the elevator control panel 21 that controls the assigned elevator, and the operation control of the actual elevator is executed. Further, in response to the assigned elevator The arrival light 3 and the output guide device 4 are controlled.

  In this embodiment, the number of elevators dedicated to the group is assigned by comparing the actual group number with the determination threshold, but the steps S47, S48 and S49 are omitted, and the group usage determined in steps S43, S45 and S46 is used. It goes without saying that an appropriate elevator number may be assigned in step S51 depending on the number of persons.

  As mentioned at the beginning, when a user inputs the number of people using a landing destination floor registration device, the representative of the group may inadvertently enter the wrong number of people, or intentionally When a situation occurs in which the number of persons different from the number of persons occurs, the number of group users is different from the actual number of persons, making it difficult to assign an appropriate elevator car, and there is a problem that operation efficiency is lowered.

  In contrast, according to the present embodiment, the number of persons estimated by the number-of-users detection means is compared with the provisional number of group users using the number buttons, and the actual number of persons is determined based on the comparison result to determine the elevator number. Therefore, the operation efficiency of the group management elevator device can be increased.

  Next, a second embodiment of the present invention will be described. In the second embodiment, a method for assigning elevators when the landing destination floor registration device 2 is not provided with the group button 7 is proposed. Here, in FIG. 5 which is the second embodiment, the constituent elements having the same reference numbers as those in FIG. 3 are the same constituent elements or constituent elements having similar functions, and therefore, redundant description thereof will be omitted.

  In FIG. 5, since there is no group button 7 in this embodiment, when the signal of the numeric button 9 indicating the floor is input to the receiving unit 10, it is determined whether the destination floor registration is by a group user, Based on this, a group correspondence processing unit 11 for performing destination floor registration including allocation of elevators of group users is newly provided.

  The group correspondence processing unit 11 shown in FIG. 5 is different in function from the group correspondence processing unit 11 shown in FIG. 3, but is common in that it has a function corresponding to a group user. The new group correspondence processing unit 11 includes functional units described below.

  First, there is provided a group number determination function unit 17 that analyzes an image in the vicinity of the landing destination floor registration device 2 acquired from the camera 31 to estimate the number of group users and determine whether or not the user is a group user. Yes. Further, the group number determination function unit 17 has a function of comparing the estimated actual number of persons with a determination threshold described later. Similar to the first embodiment, this determination threshold is used when a group-dedicated elevator is assigned.

  If the group number determination function unit 17 determines that the user is a group user, the group number determination function unit 17 receives the determination signal to determine whether a destination floor has been registered for a different floor. There is provided a destination floor registration determination function unit 32 that determines a group user at the time of registration and sends a signal for starting the allocation process to the elevator unit allocation function unit 13 based on a signal from the group number determination function unit 17. Yes.

  Here, if there are a plurality of destination floor registrations, the group determination of the group number determination function unit 17 may be inaccurate and become ambiguous. Therefore, the destination floor registration determination function unit 32 identifies the group user who is about to register at the present time. The signal for starting the assignment process is for starting the assignment process based on the comparison result with the determination threshold value from the group number determination function unit 17.

  If the destination floor registration determination function unit 32 determines that there are a plurality of destination floor registrations (in this case, it is considered that a plurality of groups are registered as the destination floors), the group by the group number determination function unit 17 Since the determination becomes ambiguous, an ambiguous correction function unit 33 is provided to send a signal to start the allocation process to the elevator unit allocation unit 13 based on the signal from the group number determination function unit 17 after correcting this. Yes. The ambiguity correction function unit 33 is inputted with the number of people from the operation learning storage function unit 34 which is referred to when the ambiguity correction function unit 33 performs correction. This correction process will be described in detail with reference to a flowchart.

  Further, after the assigned elevator number sent to the landing output control function unit 14 is notified to the output unit 6, the image acquired from the camera 31 is analyzed and moved to the vicinity of the assigned elevator number from the landing destination floor registration device 2 There is provided a moving number correction unit 35 for counting the number of group users.

  Here, the analysis of the image of the landing acquired from the camera 31 is performed, the behavior pattern of the vicinity of the landing destination floor registration device 2 and the user of the landing is analyzed, and the actual number of groups is counted in advance to obtain the optimum It is also possible to assign an elevator and notify the output unit 6 of this.

  In addition, the camera 31 sends an image of the landing situation to the group management control device 30 and performs image analysis processing on the group management control device side. May be transmitted to the group management control device 30 side.

  Next, the specific elevator unit assignment processing operation of the group management control device 30 will be described with reference to the flowcharts shown in FIGS. 6A and 6B. In this embodiment, since there is no group button 7, the group button 7 is not used to determine group use in this flowchart. One of the characteristics of this group usage determination is that it is determined whether the user is an individual user or a group user depending on the number of people detected by the user number detecting means.

Therefore, since the user does not enter the number of people in the group using the landing destination floor registration device, the representative of the group inadvertently enters the wrong number of people, or intentionally different from the number of people in the group Therefore, since the number of group users is not used by mistake, an appropriate elevator can be assigned. Hereinafter, the present embodiment will be described based on a specific flowchart.

First, the group management control device 30 monitors the input status of the landing destination floor registration device 2, and if any operation is performed in the landing destination floor registration device 2 in step S60, this is used as an input signal to register the destination floor. The landing destination floor registration process after step 61 is executed. On the other hand, if it is determined in step S60 that any operation has not been performed, the process returns to the original state and the input status of the landing destination floor registration device 2 is monitored.

<< Step S61 >>
Next, when it is determined in step S60 that some operation has been performed on the landing destination floor registration device 2, the process proceeds to step S61. In step S61, it is determined whether or not an input has been made with the numeric buttons 9 of the landing destination floor registration device 2. If the destination floor is input by the number button 9, the process proceeds to step S62. If the destination floor by the number button 9 is not input, the process returns to step S61 to monitor the number of persons input by the number button 9.

<< Step S62 >>
When the destination floor is input in step S61, in step S62, the number of groups is estimated by image analysis from the camera images in the vicinity of the landing destination floor registration device 2 that has registered the destination floor. The analysis using the camera image specifies that the person is a person by extracting the feature amount of the person, and estimates the number of persons by the sum of the person and the specified data. Such feature amount extraction is well known and a known method can be used. In addition, this step S62 may be performed between step S60 and step S61 after the input that some operation was performed in the landing destination floor registration device 2 is generated.

<< Step S63 >>
When the number of groups is estimated by image analysis of the camera 31 in step S62, the group determination value is compared with the number of groups estimated in step S62 in step S63. If the number of persons estimated from the group determination value is large, it is determined that the user is a group user. If the number of persons estimated from the group determination value is small, it is determined that the user is an individual user or a small group that can be regarded as an individual. This step 63 is a group use determination function instead of the group button 7.

  Here, the group determination value is set to about 1 to 3 people. If it is determined in step S63 that the user is a group user, the process proceeds to step S64, where elevator group assignment processing is performed by the group user.

  On the other hand, if it is determined in this step that the user is an individual user or a small group user, the process proceeds to step S70. In step S70, a process of actually assigning elevators assigned by the number of people is performed. This makes it possible to quickly call the elevator that is the target of the currently operated elevator to the floor where an individual or a small group of users are staying.

<< Step S64 >>
If it is determined in step S63 that the user is a group user, it is determined in step S64 whether this group user is one group user. In step S64, the current number of destination floor registrations is extracted, and it is determined whether there are a plurality of destination floor registrations or a single number. In the case of the singular number, it is considered that the estimation accuracy of the number of groups in step S62 is high, and the estimated number of groups is determined and the process proceeds to step S66.

  On the other hand, when there are a plurality of destination floor registrations, the number of groups estimated in step S62 may be ambiguous, including individuals or groups that have performed another destination floor registration process. . For this reason, when the number of destination floor registrations is plural, the process proceeds to step S65.

<< Step S65 >>
If it is determined in step S64 that there are a plurality of destination floor registrations, the estimated number of groups may be inaccurate, and thus the estimated number of groups needs to be corrected. For this reason, an ambiguous correction process for correcting an ambiguous state is executed in step S65.

  In this step S65, the group number from the operation learning storage function unit 34 storing the group number data storing the number of group users in the daily operation mode is compared with the group number estimated in step S62. The number of groups is corrected by comparing the number of people. Various correction methods can be considered. In this embodiment, the correction method is as follows.

  The correction of the group number is registered when the train learning memory function unit 34 learns the group number for each destination floor corresponding to the landing for each floor to obtain the learning group number, and the group user registers the destination floor. The number of learning groups on the destination floor is compared with the number estimated by image analysis of the camera 31.

  And if the estimated number of people exceeds the upper limit number of people in the learning group, a correction process is performed to change the estimated number of people to the upper limit number of people, and if it is below the lower limit number of people, it is estimated Correction processing is performed to change the number of people to the lower limit.

  Further, if the estimated number of persons is within the range between the upper limit number of persons and the lower limit number of persons, the estimated number of persons is used and the above-described correction process is not performed. Further, when the number of detected persons is one or when it is significantly below the lower limit, it can be corrected as a single user without considering it as a group user. This ambiguity correction process may be performed for elevators that are in an adjacent relationship.

<< Step S66 >>
When the number of persons estimated in steps S64 and S65 is confirmed, in step S66, the group user determination threshold is compared with the number of group users determined in steps S64 and S65 as in the first embodiment. The If the actual number of group users is larger than the determination threshold value in step S66, a group dedicated elevator is assigned. Since the technical significance of providing this step S66 is the same as that of the first embodiment, the description thereof is omitted here. Here, the determination threshold value used in step S66 is determined by the capacity of the elevator car, and when there is a large capacity, the determination threshold value is appropriately determined accordingly. Furthermore, as described above, the determination threshold value can be appropriately adjusted by learning control.

  If the actual number of group users is smaller than the determination threshold in step S66, it is not necessary to assign a dedicated elevator for the group, and it can be handled in the same way as an individual customer. Allocating a general elevator with free space. If the actual number of group users is greater than the determination threshold in step S66, the process proceeds to step S67. If the actual number of group users is less than the determination threshold, the process proceeds to step S68.

<< Step S67 >>
If it is determined in step S66 that the actual number of group users is greater than the determination threshold value, a process of assigning a dedicated elevator to be serviced only to this group user is performed. By assigning a dedicated elevator to a large number of group users in this way, it becomes possible to carry many group users to the same destination registration floor at once, and it is possible to improve the operation efficiency of the elevator Become. Since this step S67 is the same as step S48 of the first embodiment, further explanation is omitted.

<< Step S68 >>
On the other hand, if it is determined in step S66 that the actual number of group users is less than the determination threshold, a process of assigning an elevator having a space in which the number of group users can board is performed. In this way, since the group users with a small number of people can quickly assign elevators that can be boarded, it is possible to improve the operation efficiency of the elevators. Since this step S68 is the same as step S49 of the first embodiment, further explanation is omitted.

≪Step S69≫
This step S69 performs the process of actually assigning the elevators assigned according to the number of group users obtained in steps S67 and S68. This makes it possible to quickly call the elevator that is the target of the currently operated elevator to the floor where the group user is staying.

<< Step S70 >>
When the assignment of elevator cars is completed in step S69, the following process is performed on the result of the assignment process in step S70. That is, information regarding the assigned elevator number is transmitted to the output unit 6 of the landing destination floor registration device 2 to notify the group user who is performing the destination floor registration operation. The group user moves in front of the elevator assigned in accordance with this and waits for the arrival of the car.

  Further, in step S70, a command signal is transmitted to the elevator control panel 21 that controls the assigned elevator car, and the operation control of the actual elevator car is executed. Further, in response to the assigned elevator car. The arrival light 3 and the output guide device 4 are controlled.

<< Step S71 >>
When the elevator is assigned, the group user moves in front of the assigned elevator and waits for the arrival of the car. At this time, in step S71, an image relating to the movement status of the user at the landing is obtained from the camera 31, and the number of group users who have moved to the assigned elevator is extracted from the landing image by performing image analysis processing. . This process can also count the number of people moving by substantially the same process as step S62.

<< Step S72 >>
In step S72, the extracted number of moving people is notified to the elevator number allocating unit 13, and counted as the number of people entering the elevator number allocated by the elevator number allocating unit 13. Moreover, when accumulating the operation form at this time in the operation learning memory | storage function part 34, the moving number of people extracted by step S71 similarly can be used.

  In this way, unlike the first embodiment, this embodiment does not identify that the destination floor registration is used as a group by operating the group button 7 provided on the landing destination floor registration device 2, but the camera 31 and the number of groups. Since the estimation is performed by the number-of-users detection means including the determination function unit 17, a situation such as erroneous input of the group button 7 of the landing destination floor registration device 2 does not occur. Accordingly, since the number of group users can be accurately grasped, it is possible to assign an appropriate elevator and improve the operation efficiency of the elevator.

  As described above, according to the present invention, when the landing destination floor registration device is operated, the number of group users in the vicinity of the landing destination floor registration device is detected by the user number detection means and detected. Elevator units were assigned according to the number of group users. According to this, since the actual number of group users is detected by the user number detection means and the elevators are assigned, the elevators can be appropriately assigned, and the operation efficiency can be improved. become.
