Description

  Embodiments described herein relate generally to an elevator system that performs group management control of a plurality of elevators arranged side by side.

  There is an elevator system including a group management device that integrally controls the operation of a plurality of elevators. When a new hall call is generated, the group management device calculates response evaluation values from the predicted response times of all elevators to be controlled, selects an elevator that is optimal for the hall call, Dodge. The predicted response time is the travel time required for the passenger to arrive at the floor where the new hall call was made, and the stoppage time at the planned landing floor before the floor where the new hall call was made Is the sum of The stop time on the planned landing floor is the total of the preset opening / closing time of the door device and the travel time for the user to get on and off. These times are all set in advance, and the predicted response time is calculated by integrating the set times according to the conditions.

  Among them, the traveling time and the opening / closing time of the door device can be calculated almost accurately by the capacity set for the elevator. Therefore, there is almost no error from the preset value. However, the travel time of users varies greatly depending on traffic demand. That is, after calculating the response evaluation value, there is a possibility that the travel time required for passengers to actually get on and off the planned landing floor will change greatly.

  The traffic demand in a building is not average, but fluctuates according to the usage and time zone of the building. For example, the reference floor of an office building has a very high demand in comparison to other floors during work hours. Therefore, if the accuracy of the predicted response time is poor or the demand increases rapidly, the elevator cannot be assigned accurately.

  In this way, in order to cope with the increase in demand on a specific floor, the traffic demand predicted from the hall call and the hall call and the traffic demand obtained by analyzing the video of the camera installed at the hall are used. In addition, it is known that the group management device adjusts the operation pattern of each elevator.

  However, since the traffic demand of an elevator always changes, it is difficult to accurately predict the actual traffic demand from past usage records. Also, in order to understand the number of users, that is, traffic demand, by analyzing video shot by a camera installed at the hall, a camera is required for each floor. The higher the number of buildings that require elevator group control, the more cameras are required. In order to analyze these videos in real time, a large number of analysis devices or high-performance analysis devices are required. Such a configuration of the group management device is not economical as a device necessary for meeting traffic demand.

  Therefore, an elevator system is provided that includes a group management device that can accurately correspond to a plurality of elevators to actual traffic demand without cost.

An elevator system according to an embodiment includes a plurality of elevators arranged in parallel, a hall call registration device, a people counting device, and a group management device. The hall call registration device is installed at a hall on each floor of a building to register a common hall call for a plurality of elevators. The people counting device uses a stereo camera installed on each elevator of the elevator to take a picture of the range from the inside of the passenger to the landing floor on the floor where it can be seen through the door device. Measures the number of people getting on and off by calculating the three-dimensional position information of users who get on and off this boarding, and uses that did not move from the landing to the boarding until the door device was opened and closed The person is counted as the number of persons left unloaded, and the number of persons information, floor information, movement direction, and time are recorded in the storage medium as associated results. The group management device determines the elevator to be associated with the hall call based on the actual use of each elevator and the driving situation of each elevator when the hall call is registered.

The block diagram which shows the structure of the elevator system of 1st Embodiment. FIG. 2 is a perspective view showing the elevator boarding and the number of people counting device shown in FIG. 1. The flowchart which shows the operation | movement which the group management apparatus of the elevator system shown in FIG. 1 allocates an elevator with respect to a new hall call. The flowchart which shows the operation | movement which the group management apparatus of the elevator system of 2nd Embodiment allocates an elevator with respect to a new hall call.

  The elevator system 1 of 1st Embodiment is demonstrated with reference to FIGS. 1-3. The elevator system 1 shown in FIG. 1 includes a plurality of elevators 10A, 10B, 10C, and 10D arranged in parallel, and people counting devices 20A, 20B, which are installed on the elevators 11 of the elevators 10A, 10B, 10C, and 10D. Obtained by 20C, 20D, the storage medium 30 for recording information output from the number measuring devices 20A, 20B, 20C, 20D of the elevators 10A, 10B, 10C, 10D, and the number measuring devices 20A, 20B, 20C, 20D And a group management device 40 that determines elevators to be assigned to a common hall call using the obtained information.

  The elevator system 1 of this embodiment includes four elevators 10A (No. A), 10B (No. B), 10C (No. C), 10D (No. D) each having a control panel 12A, 12B, 12C, 12D. . Note that the elevator 11 and the control panel 12 constituting the elevators 10A, 10B, 10C, and 10D all have the same function. When necessary, the machine numbers A, B, C, and D will be described with reference numerals. For example, when specifying the No. 11 rider 11, it is referred to as Norikura 11A. Similarly, the configuration of the person counting devices 20A, 20B, 20C, and 20D is also necessary whenever it is necessary to identify the aircraft numbers A, B, C, and D of the corresponding elevators 10A, 10B, 10C, and 10D. It will be attached accordingly.

  Each of the person counting devices 20A, 20B, 20C, and 20D includes a stereo camera 21 and an image analysis device 22 as shown in FIGS. The stereo camera 21 is installed on the top of the elevator 11 of the elevators 10 </ b> A, 10 </ b> B, 10 </ b> C, and 10 </ b> D, and can be seen from the interior of the passenger 11 through the door device 13 so that a user passing through the door device 13 can be photographed. The range up to the landing 101 on the floor on which the floor is landed is photographed. The image analysis device 22 calculates the three-dimensional position information of the users who get on and off the ride 11 based on the video taken by the stereo camera 21, and measures the number of users who get on and off each floor. The image analysis device 22 includes the measured number information, the floor information indicating the floor where the number is measured, the moving direction of the ride 11 before and after stopping on the floor, and the time when the number is measured. Is output as a usage record that associates. The floor information and the moving direction are obtained from the control panel 12 of the elevators 10A, 10B, 10C, 10D where the person counting devices 20A, 20B, 20C, 20D are installed.

  As shown in FIG. 2, the stereo camera 21 includes two cameras 21 </ b> R and 21 </ b> L having different shooting angles by being arranged in parallel with the door device 13 and separated in the horizontal direction. By performing the analysis process based on the parallax of the images simultaneously captured by the two cameras 21R and 21L, it is possible to specify the three-dimensional positions of various subjects that are not limited to humans appearing in the images. The image analysis device 22 extracts a user from the video imaged by the stereo camera 21 and tracks the user to determine whether the user has got off the ride 11 or got on the ride 11. Judge with.

  The stereo camera 21 also takes a picture of the hall 101 that is visible through the door device 13. Therefore, the image analysis device 22 can also exclude from the number of passengers a user who once exits the landing 101 and returns to the riding board 11 in order to make a way. In addition, the people counting devices 20A, 20B, 20C, and 20D measure the number of users who remain on the landing 101 without getting on the ride 11 because the ride 11 is almost full or exceeds the full. Furthermore, since the person counting devices 20A, 20B, 20C, and 20D can capture the user three-dimensionally by detecting the three-dimensional position of the user with the stereo camera 21, the user information, that is, the back It is possible to detect the physical characteristics of the user such as whether the user is high or low, whether the user is accompanied by a large baggage or a stroller, and whether the person is a disabled person using a wheelchair or a cane by pattern matching.

  By doing in this way, people counting device 20A, 20B, 20C, 20D measures correctly the number of users who actually got on and off. In addition to this, the person counting devices 20A, 20B, 20C, and 20D are actually required for the user to get on and off the ride 11 by analyzing with the image analysis device 22 based on the images taken by the stereo camera 21. The boarding / alighting time, the door operating time required to open and close the door device 13, and the user information are obtained. These pieces of information may also be output in association with the actual usage.

  The storage medium 30 records usage records output from the number of people counting devices 20A, 20B, 20C, and 20D of the elevators 10A, 10B, 10C, and 10D, and provides information to the group management device 40 as necessary. One storage medium 30 may be provided corresponding to the number of people counting devices 20A, 20B, 20C, and 20D of all elevators 10A, 10B, 10C, and 10D that are group-managed, or the number of people counting devices 20A and 20B. , 20C, 20D, one storage medium 30 may be prepared.

  As shown in FIGS. 1 and 2, each call board 11 is provided with a call registration device 14 for inputting a destination floor. The destination floor information input from the call registration device 14 is input to the control panel 12 of the elevators 10A, 10B, 10C, and 10D and also provided to the group management device 40. Also, a hall call registration device 102 that is prepared in common to call any one of the elevators 11A, 10B, 10D, and 10D is installed at the hall 101 and is input from the hall call registration device 102. The hall call information is provided to the group management device 40. Both the call registration device 14 and the hall call registration device 102 are operated by an unspecified user and are generally a destination floor button and a hall button in many cases.

  The group management device 40 uses each of the plurality of elevators 10A, 10B, 10C, and 10D recorded in the storage medium 30 and the elevators 10A and 10B when the hall call information is input by the hall call registration device 102. , 10C, and 10D, the elevators 10A, 10B, 10C, and 10D to be associated with the hall call are determined. As shown in FIG. 1, the group management device 40 includes a habit call control unit 41, a hall call control unit 42, an operation pattern switching unit 43, an allocation control unit 44, and a demand recording unit 45. In the case of this embodiment, the demand recording unit 45 is provided in a part of the storage medium 30.

  The call controller 41 registers the destination floor information output from the call registration device 14 via the control panel 12 of each elevator 10A, 10B, 10C, 10D. This destination floor information includes identification information indicating which of the registered elevators 10A, 10B, 10C, and 10D is present, information indicating the destination floor, which floor floor service is performed, etc. Is included. The hall call control unit 42 registers the hall call information output from the hall call registration device 102. The hall call information includes information indicating the floor on which the hall button is pressed and the destination direction that specifies whether the hall button is upward or downward.

  The driving pattern switching unit 43 switches the driving pattern according to a preset condition based on the usage record output from the image analysis device 22 of each elevator 10A, 10B, 10C, 10D. The utilization results adopted at this time include the latest number of passengers, number of passengers, and number of passengers left. Here, the “passenger” is a user in the state of riding on the ride 11, and the “passenger” includes both a passenger who has entered the ride 11 and a passenger who has got off the ride. .

  The assignment control unit 44 operates the operation information obtained from the control panel 12 of each elevator 10A, 10B, 10C, 10D and the elevators 10A, 10B, 10C for the hall call registered by pressing the hall button on each floor. The response evaluation values F (k) of the elevators 10A, 10B, 10C, and 10D are calculated based on the past use results output from the 10D person counting devices 20A, 20B, 20C, and 20D, and then the response evaluation is performed. The elevator with the highest value F (k) is assigned. At this time, “k” is an index corresponding to the elevator number (base), and in this embodiment, k = 0 to 3 is set corresponding to each of the four elevators A to D. take. Here, the “response evaluation value” is an index for determining which elevator car 11A, 11B, 11C, 11D is optimally assigned to a new hall call.

  In order to calculate the response evaluation value F (k), the allocation control unit 44 employs the latest usage record immediately before the hall call is registered in addition to the past usage record and the current driving information. In this embodiment, the current driving information and the latest usage record are handled as so-called “real time” driving information. Therefore, in this driving information, each elevator 10A, 10B, 10C, 10D when a new hall call is registered, the position of the carriage 11, the moving direction of the hall 11, and the floor where the hall call is registered. It includes the planned flooring already registered before the arrival of the saddle 11 and the number of passengers on the ride 11.

  The allocation control unit 44 is estimated to get on and off at the planned landing floor based on the past use record corresponding to the time when a new hall call is registered, based on the past use record and driving situation information. Estimate the number of passengers to get on and off. Furthermore, the allocation control unit 44 opens and closes the door device 13 on the scheduled landing floor, the travel time T1 required to move to the floor on which the landing call is registered based on the position of the planned landing floor already registered. The door operation time T2 required for this and the replacement time T3 required for the user to get on and off the planned landing floor are calculated based on the planned number of passengers calculated for each planned landing floor.

  The response evaluation value F (k) is calculated by the allocation control unit 44 for each of the elevators 10A, 10B, 10C, and 10D each time a new hall call is generated. The response evaluation value F (k) includes a predicted response time X (k), a riding congestion degree W (k), a leftover variable V (k), and the like. The predicted response time X (k) is the sum of the travel time T1, the door operation time T2, and the replacement time T3. The riding congestion degree W (k) is a factor based on the number of passengers obtained by the person counting devices 20A, 20B, 20C, and 20D. The unloading variable V (k) is a fluctuation function of the number of users who will newly get on the planned landing floors up to the floor where the hall call occurred, and is caused by the elevators of other units. This is the rate of change in the number of people left on the planned floor. The waiting number assumed at the time of landing is estimated by applying a waiting time to the unloading variable V (k).

At this time, passengers are expected to get off on the planned landing floor unless there is no planned landing floor between the floor where the hall call occurred and the situation is almost full (100%). The haze congestion degree W (k) is not a factor to be taken into account. Also, unless the scheduled floor is not only based on the assigned hall call, passengers will surely get off at the planned ground floor, so the unloading variable V (k) is also a factor to be taken into account. Absent. Accordingly, the factor for determining the response evaluation value F (k) is approximately the predicted response time X (k), and the following relationship is established.
F (k) = X (k) = F (Σ (T1 + T2 + T3))
The response evaluation value F (k) calculated by the above formula is stored in the demand recording unit 45. When the response evaluation value F (k) is calculated for each of the elevators 10A, 10B, 10C, and 10D, the assignment control unit 44 compares the response evaluation values F (k) of the elevators 10A, 10b, 10C, and 10D. An elevator with a high response evaluation value F (k), for example, an elevator with an estimated arrival time that can arrive at the floor where the hall call is registered is assigned as a service elevator that responds to the hall call.

  However, as described above, the response evaluation value is not determined because the estimated arrival time is early. For example, even if it arrives first at the hall call registration floor, if the rider 11 is almost full, a new number of unloaded persons will be generated. Also, if there are many passengers waiting on the landing call registration floor, it is not possible to put all the passengers by assigning only one of the elevators 10A, 10B, 10C, 10D. Furthermore, when the hall call registration floor has been registered as an expected landing floor in an elevator other than the assigned elevator, a plurality of landings 11 arrive at the hall call registration floor with a time difference of several seconds, that is, for the hall call Oversupply.

  The replacement time T3 is a value that varies greatly depending on how many passengers get on and off the planned landing floor. Therefore, the group management device 40 in the elevator system 1 of the present embodiment is the number of people actually getting on and off obtained by the number of people counting devices 20A, 20B, 20C, and 20D of the elevators 10A, 10B, 10C, and 10D and the actual number required for it. Each time the measurement time stops at the planned landing floor, it is updated sequentially, and based on the conditions, the response evaluation values F (k) of the elevators 10A, 10B, 10C, 10D for all hall calls are recalculated, Newly reassign.

  At this time, in order to calculate the response evaluation value F (k) more accurately, the response evaluation value F (k) is estimated as a variable for varying the response evaluation value F (k) when the rider 11 arrives at the floor where the hall call is registered. In addition to the above factors, such as the passenger congestion degree W (k) based on the number of passengers and the unloading variable V (k) for calculating the waiting number estimated to be waiting at each landing call registration floor The response evaluation value F (k) is determined in consideration of whether the floor on which the hall call is registered is included in the planned landing floor, the number of passengers estimated to get off on the planned landing floor, etc. May be. When the assignment control unit 44 employs the response evaluation value F (k) weighted by these variables, the operation efficiency of each elevator 10A, 10B, 10C, 10D is improved.

Next, operation | movement of the above-mentioned elevator system 1 is demonstrated with reference to FIG.
FIG. 3 is a flowchart showing the operation of the assignment control unit 44 that assigns elevators according to hall calls in the elevator system 1. Each process shown in this flowchart is executed by the group management device 40 reading a program recorded in advance in a storage medium such as a ROM.

  When the operation of the elevator system 1 is started, the assignment control unit 44 provided in the group management device 40 initializes set values and the like (S0). Operation information such as operation direction, load, position, and assignment is read from the control panel 12 of each elevator 10A, 10B, 10C, 10D by the record selection program (S1).

  When the hall call is registered from the hall call registration device 102, a positive value is input to the value i for identifying the hall call (S2). The value i may be called an index. There are as many types for identifying hall calls on all floors as twice the number of floors N, excluding the UP call on the top floor and the DOWN call on the bottom floor. Therefore, if i is a value starting from zero “0”, the value of i takes 0 to (2N−3).

  In this embodiment, the value i is associated with an integer that continues from zero “0” in order from the DOWN call on the top floor to the DOWN call on the top floor of the bottom floor with respect to the DOWN call. The DOWN call is associated with an integer that continues from the UP call on the bottom floor to the UP call on the bottom floor of the top floor with respect to the UP call. For example, in a three-story building, the DOWN call on the third floor, which is the top floor, is zero “0”, the DOWN call on the second floor is “1”, the UP call on the first floor is “2”, and the UP call on the second floor “3”, the value i takes four types of values from 0 to 3. In FIG. 3, the value i = 0. The value i may be associated with the hall call in an order other than the above. For example, starting from the DOWN call on the top floor, one lower floor UP call and DOWN call may be assigned, and further down to the bottom floor, the serial numbers may be associated in sequence up to the bottom floor UP call. Sequential numbers may be associated from the UP call of the floor to the DOWN call of the top floor.

  When the hall call is registered, the allocation control unit 44 determines the state of the hall call (S3). A state in which a hall call is registered but none of the elevators 10A, 10B, 10C, 10D is assigned as a service elevator is “01 mode” (S4), and a service elevator is already assigned to the hall call registration. “11 mode” (S 5), “10 mode” (S 6) when the assigned service elevator is responding on the floor where the landing call is registered, and the assigned service elevator when the response to the landing call is completed. A state in which there is no new hall call and no new hall call is defined as “00 mode” (S7).

As a result of the determination in S3, when it is determined that the mode is 01 mode (S4), the response evaluation values F (k) of the elevators 10A, 10B, 10B, and 10D are sequentially confirmed. At this time, the variable k for identifying the elevator is replaced with k = Ci in order to associate with the value i of the hall call. In the case of this embodiment, since the elevators 10A, 10B, 10C, and 10D are four, Ci can take a value of 0 to 3. Specifically, Ci = 0 for Unit A, Ci = 1 for Unit B, Ci = 2 for Unit C, and Ci = 3 for Unit D. Therefore, the allocation control unit 44 sets Ci = 0 (S8), and calculates a response evaluation value F (i) for the elevator call 10A of the No. A elevator with respect to the landing call value i (S9).

  The response evaluation value F (i) is the travel time T1 of the elevators 10A, 10B, 10C, 10D, the door operation time T2 in all planned landing floors, and the image analysis device 22 of the person counting devices 20A, 20B, 20C, 20D. It is determined by the predicted response time X (i) obtained from the sum of the replacement times T3 for all scheduled floors calculated based on the obtained analysis results and past usage results.

  The travel time T1 is the sum of the times t1 during which the carriage 11 moves on each planned landing floor up to the floor where the hall call is registered. The time for accelerating to the planned landing floor or decelerating to stop at the planned flooring and the time during the movement between floors can be calculated based on the specifications of the elevator and the travel distance. The door operation time T2 is the sum of the time t2 required for the door device 13 to be opened and closed on the planned landing floor, and can be calculated based on the size of the frontage and the specifications of the door device 13.

  The replacement time T3 is the sum of time t3 required for the user to get on and off the scheduled landing floor. The number of users getting on and off at each planned floor will vary even if the same conditions such as time of day and day of the week are met. Therefore, the replacement time T3, which is the sum of t3 of each planned floor planned when the response evaluation value F (i) is calculated, varies greatly.

  Therefore, in the present embodiment, when elevators of other units have landed on each planned landing floor first, the time actually measured at that time and the number of unreserved persons or unreserved variables V (i) actually measured by the person counting device Is used to calculate the estimated time te3 required for the user to get on and off the scheduled landing floor, and use this to determine the replacement time T3. By using the predicted time te3, the error in the replacement time when actually landing on the planned floor is reduced, so that it is possible to calculate an accurate response evaluation value F (i). If there is no track record of the arrival of an elevator of another unit or sufficient unloading variable V (i) with respect to the planned landing floor, the time t3 set in advance on the planned landing floor is used for replacement. Time T3 is calculated.

  The allocation control unit 44 that has calculated the response evaluation value F (i) in S9 for the elevator of the unit selected in S8 determines whether the operation of S9 has been completed for all elevators 10A, 10B, 10C, and 10D (S10). . If not completed (that is, if Ci = 3), the value of Ci is incremented by 1 to calculate the response evaluation value F (i) of the remaining elevator (S11), and the response evaluation value F of the next elevator is calculated. (i) is calculated (S9).

  When the response evaluation values F (i) are obtained for all the elevators 10A, 10B, 10C, and 10D, the optimum elevator to be assigned to the hall call is determined (S12). The allocation control unit 44 outputs allocation information to the elevator control panel 12 determined as the service elevator (S13), and completes one allocation operation.

  When a series of assignment operations in S3 to S13 is completed for one hall call registration, the assignment control unit 44 confirms whether all service elevators arranged for all hall calls have arrived at the hall call registration floor. (S14). If it is not completed, for example, when a new hall call occurs during the assignment work, a series of steps from mode determination (S3) to the hall call to output of the assignment information to the corresponding elevator control panel 12 (S13). Repeat the operation.

  In the mode determination (S3), when it is determined that there is no landing call and there are 10 remaining assignments (S6), that is, when the service is being performed for the landing call, the process proceeds to S14 when the service is completed.

  If it is determined in the mode determination (S3) that the 11 mode (S5) is assigned to the hall call, the allocation control unit 44 actually measures the time t3 on the planned landing floor. When this happens, the latest response evaluation value Fn (i) of the assigned hall call is calculated. The allocation control unit 44 compares the response evaluation value F (i) when assigned to the elevator with the latest response evaluation value Fn (i) (S17).

  For example, when the actual measurement time tm3 is longer than the predicted time te3 for the planned landing floor, the latest predicted response time Xn (i) is longer than the initial predicted response time X (i). In addition, when the number of passengers counted by the number counting device 20 is almost full or gradually increasing, there is a possibility that the passenger will be left on the floor of the hall call.

  Therefore, when the latest response evaluation value Fn (i) is lower, the allocation control unit 44 determines that a long wait or unloading occurs when the elevator currently allocated to the hall call is arranged. If the latest response evaluation value Fn (i) has little or no difference from the previous response evaluation value F (i), the assignment is maintained.

  The allocation control unit 44 cancels the assignment of the hall call to the elevator having the highest response evaluation value F (i) at that time (S18), and shifts to the 01 mode (S4). To do. The allocation control unit 44 selects an elevator with a high response evaluation value according to the allocation flow routine FL shown in S8 to S13 of FIG. 3, and reassigns the hall call.

  In 11 mode (S5), calculating the latest response evaluation value Fn (i) for the assigned hall call and reassigning the hall call as necessary means that all hall calls that have already been assigned. To be done.

  Thus, according to this elevator system 1, when the response evaluation value F (i) is re-evaluated in S17, it is necessary for the user to get on and off the scheduled landing floor up to the target floor of the hall call. One of the predicted times te3 set as the time t3 is replaced with the actually measured time tm3. In addition, in order to calculate the predicted time te3, the actual measurement time tm3 of another elevator, the unloading variable V (i) reflecting it, the actually measured unloading number, and the like are used. Therefore, an accurate response evaluation value F (i) can be calculated as compared with a case where the response evaluation value is calculated using a preset door movement time. As a result, the elevator system 1 can always service the elevator of the optimal number for the hall call.

  Operation | movement of the elevator system 1 of 2nd Embodiment is demonstrated with reference to the flowchart shown in FIG. Since the configuration of the elevator system 1 is the same as that of the first embodiment, the detailed description of each configuration takes into account the description of the first embodiment and FIGS. And in the following description, the same code | symbol is attached | subjected to the structure which has the same function as the elevator system 1 of 1st Embodiment.

  Moreover, the elevator system 1 of 2nd Embodiment operate | moves according to the substantially the same flowchart as the elevator system 1 of 1st Embodiment. Therefore, in the flowchart of FIG. 4, the same reference numerals are given to portions where the same processing is performed, and the description of the first embodiment is referred to for the description. About operation | movement of the elevator system 1 of 2nd Embodiment, the part from which operation | movement differs compared with the flowchart of the elevator system 1 of 1st Embodiment is demonstrated.

  The flowchart shown in FIG. 4 shows an operation in which the group management device 40 provided in the elevator system 1 switches the operation pattern. The group management apparatus 40 according to the second embodiment differs from the first embodiment in the processing in the 10 mode (S6).

  In the following, an example will be described in which the elevator 10A of No. A is already assigned as a service elevator among the elevators 10A, 10B, 10C, and 10D for the hall call. As a result of the mode determination performed by the group management device 40 (S3), the case of the 10 mode (S6) in which the elevator 10A is responding will be described.

As shown in FIG. 4, in the 10 mode (S6), the allocation control unit 44 of the group management apparatus 40 checks whether or not there is any unloading (S19). When the number measuring device 20A of the elevator 10A counts the number of unloading, the group management device 40 determines that there is unloading, and whether or not it is necessary to assign a second elevator to the landing call registration floor. (S20). For example, the group management device 40 determines whether it is necessary to allocate the second elevator by comparing the congestion status and waiting time between the hall call registration floor and other floors.

When it is determined that the second elevator needs to be allocated, the group management device 40 determines whether there is another elevator that has already been decided to land on the landing call registration floor, that is, the allocated flag. Is checked (S21). If the allocation flag is not set, the allocation of the second unit is performed by the allocation flow routine FL. Then, a second flag is set in the elevator assigned as the second elevator (S22). The details of the allocation flow routine FL are the same as S8 to S13.

  The driving pattern switching unit 43 outputs a command for switching the driving pattern to the control panel 12 of the elevator 10 assigned to the second elevator. Here, the description will be continued below assuming that the elevator 10B of Unit B is assigned to the second elevator. When the response evaluation value F (i) of the elevators 10B, 10C, 10D of the B to D units is lower than the response evaluation value F (i) of the elevator 10A of the A unit as the second elevator, The elevator 10A may be selected as the second elevator.

  While the operation pattern is being switched, during the 10 mode (S6), the presence or absence of unloading is always checked in S19 and S20, and the necessity for the second unit allocation is always checked. While the above-described conditions are continued, the control for allocating a plurality of elevators to the remaining floor is continued.

  When the first elevator 10A arrives at the landing call registration floor and it is confirmed that there are no unloaded persons in the number measuring device 20A, the second flag of the elevator 10B of the B-unit that is the second elevator is set. Release (S23). Also, even if there is an unloading, the elevator 10A of Unit A is selected as the second elevator, or the elevator 10B of Unit B arrives at the landing call registration floor as the second elevator. Even if it is confirmed that there is no unloading in the person counting devices 20A and 20B and it is determined that the second unit allocation to the Unit B is not necessary, the second unit flag is canceled (S23). When the second flag is released, the elevator system 1 returns to the normal operation pattern.

  As described above, the elevator system 1 uses the stereo camera 21 to obtain the number of passengers, the number of passengers, the number of unloaded passengers, and the boarding time required for each user obtained by the person counting devices 20A, 20B, 20C, 20D. By accurately measuring based on the original position information, the response evaluation values F (i) of the elevators 10A, 10B, 10C, and 10D with respect to the hall call registration floor can be accurately calculated. In addition, based on past usage records obtained by the number counting devices 20A, 20B, 20C, and 20D, the number of users expected to get on and off the boarding before reaching the landing call registration floor is calculated. Therefore, it is possible to predict with high accuracy the replacement time required to get on and off the carriage 11 at each of the floors that stop before reaching the landing call registration floor. Therefore, since the accuracy of the response evaluation value calculated based on these becomes high, the operation efficiency of the elevators 10A, 10B, 10C, 10D arranged by the allocation control unit 44 is improved.

  Further, information that can be employed other than the above in order for the allocation control unit 44 to calculate the response evaluation value will be described. The elevator system 1 according to the present embodiment includes people counting devices 20A, 20B, 20C, and 20D in all elevators 10A, 10B, 10C, and 10D that are group-managed. The person counting devices 20A, 20B, 20C, and 20D are equipped with a stereo camera 21 and track the trajectory of each user by recognizing the user who gets on and off the rider 11 from the three-dimensional position information. Then, it is accurately determined whether the rider 11 gets on or off.

  By installing these people counting devices 20A, 20B, 20C, and 20D, each user can get on the basis of an image when each user on the rider 11 gets on the rider 11. The boarding time required to get on the kite can be recorded accurately. Therefore, the allocation control unit 44 estimates the exit time required for each user to get out of the rider 11 based on each user's boarding time, and the boarding time of the user riding on the rider 11 is estimated. The replacement time required for calculating the response evaluation value may be set by averaging the output time and the exit time. As described above, by calculating the response evaluation value using the replacement time suitable for the user who is currently on the rider 11, the error of the response evaluation value is further reduced. The elevators 10A, 10B, 10C, and 10D can be assigned accurately.

  In addition, the elevator system 1 is equipped with the people counting devices 20A, 20B, 20C, and 20D, so that images taken by the stereo camera 21 while the passenger 11 is landing on the landing call registration floor are displayed. Based on this, the image analysis device 22 calculates the number of people who have boarded the riding board 11 and the number of people who have not been able to get on the boarding board. The allocation control unit 44 compares the number of persons estimated from the past usage record with the actual number of unloading persons, and if the actual number of unloading persons exceeds the estimated value, the hall control is automatically registered, and the elevators 10A, 10B, 10C, Increase the allocated number of 10D. Thereafter, when the allocation control unit 44 determines that the remaining number of passengers can be collected by an elevator that arrives late, the automatic registration of the hall call is canceled.

  Even if the user concentrates in the time zone including the end time of the meeting or the event on the floor including the opening of the meeting or the event, the elevator system 1 assigns the elevator with priority. Therefore, it can be transported smoothly without making the user wait for a long time.

  In addition, when the elevator system 1 has a designated floor standby operation function such as waiting in a door open state until a certain number of passengers are reached on the reference floor or until a certain time elapses during the working hours, When the remaining number of designated floors detected by the devices 20A, 20B, 20C, and 20D exceeds the estimated demand number estimated based on the past usage record, the allocation control unit 44 of the group management device 40 is assigned to the designated floor. When the number of elevators to be waited is increased and falls below the planned demand, the allocation control unit 44 reduces the number of elevators to be waited at the designated meeting and cancels the designated floor standby operation.

  Furthermore, in this elevator system 1, when the passengers 11 of the elevators 10A, 10B, 10C, 10D that have started in the full state are opened on the scheduled landing floor where the call is registered, the person counting devices 20A, 20B, 20C, Based on the number of passengers and unloading passengers detected by 20D, the allocation control unit 44 recognizes the floor where the user flow is stagnant, that is, the floor where the service is decreasing. Then, the allocation control unit 44 arranges another elevator and prohibits additional allocation to the newly arranged elevator. In this way, by assigning and controlling the elevators 10A, 10B, 10C, and 10D, it is possible to reliably reduce the floor where the service is deteriorated.

  When this elevator system 1 is adopted in a hotel that places importance on private use, based on the latest number of passengers measured by the person counting devices 20A, 20B, 20C, and 20D and the destination floor information registered for calling, The allocation control unit 44 allocates an elevator that reduces the number of passengers to board when the rider 11 reaches the floor where the hall call is registered. This makes it possible to minimize the contact between hotel guests and to ensure the privateness of the users.

  The elevator system 1 also includes people counting devices 20A, 20B, 20C, and 20D that are equipped with a stereo camera 21. Therefore, the elevator system 1 can detect the appearance feature of the user riding on the riding rod 11 as three-dimensional position information. Therefore, the detected three-dimensional position information is analyzed, and the image analysis device 22 is used for a physically handicapped person using a wheelchair or a walking aid, a visually handicapped person using a walking stick, a person with a large baggage, a walking speed. It is determined whether a late person is included in the user, and this is output as user information. The appearance features of these users are detected by determining the characteristic shape (for example, the shape of a wheelchair) identified based on the three-dimensional position information, or by the movement of the user identified based on the three-dimensional position information. This is performed by determining whether the speed is equal to or lower than a preset speed.

  When the person counting devices 20A, 20B, 20C, and 20D output such user information, the group management device 40 opens the door device 13 and then the user corresponding to the user information moves toward the door device 13. It detects that it has started to move, and changes the opening time of the door devices 13 of the elevators 10A, 10B, 10C, 10D to be longer than usual.

  The elevator system 1 includes an elapsed time from when the individual user detected by the image analysis device 22 of the person counting devices 20A, 20B, 20C, and 20D gets on the ride 11 until it gets off, and an unanswered time for the hall call. Has the function of calculating the time to complete the service of the elevators 10A, 10B, 10C, 10D.

  In addition, the elevator system 1 adds the number of users getting on and off during the day detected by the person counting devices 20A, 20B, 20C, and 20D for each floor, thereby calculating the number of visitors in each floor and building. Has a function to calculate. By providing the number of visitors obtained by this function to the building management room or security company, it can be used for building management such as air conditioning and crime prevention.

  The elevator system 1 records the usage record obtained by the person counting devices 20A, 20B, 20C, and 20D in the storage medium 30. Therefore, the group management device 40 includes the number of users who get on and off the ride 11, the time required for the user to get on and off the ride 11, the operation time required to open and close the door device 13, and the service completion time. The traffic demand information such as is extracted from the storage medium 30 for each set time period. The extracted traffic demand information is used for a learning function for adjusting an elevator driving pattern.

  In addition, the usage results are sorted by time zone and floor, and used immediately, such as the number of passengers, the operating time of door devices, the replacement time of users on each floor, the number of visitors in the building, and traffic demand information. It may be recorded in the storage medium 30 as useful information that can be obtained.
