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

(First embodiment)
FIG. 1 is a block diagram showing the configuration of an elevator group management system according to the first embodiment.

  The group management control device 11 in this embodiment includes a power saving target setting unit 12, a hall call information input unit 13, a hall information acquisition unit 15, an operating number calculation unit 14, an allocation control unit 16, a power saving target storage unit 51, an operation. A unit number storage unit 52 and an operating unit number calculation reference storage unit 53 are provided.

About the power saving target setting unit 12 The power saving target setting unit 12 sets a power saving target value in a predetermined period (for example, a medium to long term such as 30 minutes or 1 hour) by a predetermined operation. Specifically, the target value of the average number of cars in operation is set as a power saving target value through a dedicated terminal device attached to the group management control device 11. In addition, you may set using the terminal device installed in the landing or the cage | basket, or general purpose terminal devices, such as PC. Further, a target value of power consumption may be set as the power saving target value.

-About the hall call information input part 13 The hall call information input part 13 inputs the hall call information registered by the hall call registration apparatus 2a, 2b ... installed in the hall of each floor. The hall call registration devices 2a, 2b,... Only the down button is installed on the top floor, and only the up button is installed on the bottom floor. When the user presses this button, hall call information including information on the floor and the direction of the destination (up / down) is sent to the hall call information input unit of the group management control device 11 via a transmission cable (not shown). 13.

-About the hall information acquisition part 15 The hall information acquisition part 15 receives the hall information obtained from the hall information detection apparatus 3a, 3b ... installed in the hall of each floor. The hall information includes some or all of the following. Among these, at least the information (a) is included.

(A) Number of people waiting at the landing on each floor (b) Waiting time for each user waiting for an elevator at the hall on each floor or a group of people (groups close to each other) (c) Wheelchair use, cart use, etc. The presence or absence of a person who is inconvenient to use the elevator (d) Additional information indicating that the person waiting for the elevator is an ID or a specific type (for example, VIP). Here, as the landing information detection devices 3a, 3b,. Is used. In other words, a camera is installed at the hall on each floor, and by analyzing the image of the camera, the user is specified, and hall information such as the waiting number and waiting time is detected in real time.

  “Real time” as used herein includes the meaning of “immediately” or “immediately”. That is, even if a camera is used, there is time to analyze the image of the camera, and therefore the situation of a user waiting for an elevator at a landing on each floor is detected immediately or almost immediately.

  As a method for detecting the number of waiting persons, there is, for example, “JP 2012-26608 A: energy consumption management system and energy consumption management device”. Further, as a method for specifying a user using a camera, for example, there is “Patent No. 4594945 gazette: person search device and person search method”.

  In addition to the camera, a method of acquiring waiting time and personal information of each user waiting at the landing using RFID (Radio Frequency Identification) or the like may be used. Furthermore, a method using a personal authentication device may be used.

-About the number-of-operating-units calculation unit 14 The number-of-operating-unit calculating unit 14 calculates the number of cars in operation at predetermined time intervals (for example, 30 seconds) based on the power saving target value, landing information on each floor, and the number-of-operating-unit calculation standard. . The calculation method will be described later in detail.

Assignment control unit 16 The assignment control unit 16 performs assignment control of the cars 4a, 4b,... For the hall calls on each floor, with the number of cars in operation calculated by the operation number calculation unit 14 as a constraint. At that time, not only the hall call information but also the waiting number of hall information may be used. As a specific allocation control method, a generally known method is used. For example, as a method for detecting the number of waiting persons and assigning hall calls based on the detection result, there is "Japanese Patent Application Laid-Open No. 2006-232446: Group management elevator".

Power Saving Target Storage Unit 51 The power saving target storage unit 51 stores the target value of the average number of cars in operation or the target value of power consumption set as the power saving target value by the power saving target setting unit 12.

  In this case, if it is the target value of the average number of cars in operation, for example, the number of cars such as 2.5 may be stored, or a ratio of 80% of cars in operation may be stored. If it is the target value of the power consumption, for example, a numerical value such as 100 [kWh] may be stored, or a ratio such as 60% of the rated power consumption (for example, 200 [kWh]) may be stored.

-About the operating unit result storage unit 52 The operating unit result storage unit 52 displays the operating unit result calculated based on the operating unit calculated by the operating unit calculation unit 14 and the time when the operating unit is applied to the group management system. Remember.

  The actual number of operating units is calculated as follows, for example.

    1. When a predetermined period (for example, 1 hour = 3600 seconds) ends, the actual number of currently operating units is reset to zero.

    2. Each time the number of operating units is calculated by the operating unit calculating unit 14 at a predetermined time interval (for example, 30 seconds), the actual number of operating units is updated by the equation (1).

Actual number of operating units = Actual number of operating units + Number of operating units x (predetermined time interval / predetermined period) (1)
When the target value of power consumption is set as the power saving target, the actual result of power consumption is stored. The power consumption may be an actual value measured using a watt-hour meter, or may be a value calculated from information related to elevator operation (such as car load and driving distance).

-About the operating number calculation reference | standard storage part 53 The operating number calculation reference | standard storage part 53 memorize | stores the reference value of the operating number calculation used by the operating number calculation part 14. FIG. For example, as shown in FIG. 2, a correspondence table 53 a between the average waiting number and the number of operating units may be stored in the operating number calculation reference storage unit 53. In this case, the operating number corresponding to the average waiting number of passengers at the hall is used as the reference value.

  Further, for example, a method of calculating the number of operating units according to the equation (2) may be used. In this case, a numerical formula or a constant in the mathematical formula (α in this example) is stored in the operating number calculation reference storage unit 53 as a parameter.

Number of operating units = average number of people waiting [person] x α (2)
However, rounding up of the decimal point and the number of operating units are, for example, up to 3 units.

  In such a configuration, a method of calculating the number of operating cars assuming that the target value of the average number of cars operating is set as the power saving target will be described.

  FIG. 3 is a flowchart showing the operation number calculation processing of the elevator group management system. In addition, the process shown by this flowchart is performed by the operation number calculation part 14 of the group management control apparatus 11. FIG.

・ About the number of operating units The number of operating units is the actual number of operating units at a certain point in time as a result of changes in operating units from moment to moment. The actual number of operating units can be obtained by equation (3). In addition, this (3) Formula only expressed the said (1) Formula mathematically, and, as a result, is the same.

  t is the time when the calculation period (for example, 10 minutes) of the average car operation number is divided by the operation number update interval (for example, 100 seconds) (600 seconds / 100 seconds = 6, t = 1, 2, 3, 4, 5, 6). The operating number (t) is the operating number of cars at time t.

  For example, assuming that the average car operation number calculation period is 600 [sec] and the operation number update interval is 100 [sec], the operation number is 2 [units] → 2 [units] → 1 [units] → 100 [sec] → It is assumed that 1 [unit] → 3 [unit] → 2 [unit] is calculated.

The actual number of units in operation at this time is
(2 + 2 + 1 + 1 + 3 + 2) × 100/600 = 1.8 [unit]
It becomes. The number of operating units is determined so that the actual number of operating units does not exceed the target value of the average car operating unit.

・ About the provisional number of operating units The provisional number of operating units target is the target value of the number of operating units at a certain point in time. The provisional operation number target is obtained by the following equation (4).

Temporary working unit target [unit] = t × target value of average car operating unit [unit] × operating unit update interval [sec] / average car operating unit calculation period [sec] (4)
・ About the total value of the landing information Calculate the total value for calculating the number of operating units from the floor information on each floor. As the total value, for example, the following values can be considered.

(A) Average number of people waiting on the floor divided by the total number of people waiting on all floors
(B) Calculate the number of waiting people x maximum waiting time for each floor, and average the values
(C) Total value of waiting time of each user.

  The number-of-operating-unit calculating unit 14 executes the following number-of-operating-unit calculation processing at a predetermined number of operating unit update intervals such as 30 seconds.

  That is, first, the operating number calculation unit 14 determines whether or not an average car operating number calculation period (for example, one hour) has elapsed (step S1). When the time has elapsed (YES in step S1), the operating unit calculation unit 14 resets the operating unit result stored in the operating unit result storage unit 52 to 0 (step S2) and the provisional operating unit target. Is reset to 0 (step S3).

  After resetting the actual number of operating units and the provisional operating unit target, the operating unit calculating unit 14 adds the target operating unit x the operating unit update interval to the provisional operating unit target during the above calculation period (for example, 1 hour) and provisional operation. The number target is updated (step S4).

  In addition, the operating number calculation unit 14 collects the hall information of each floor from the hall information acquisition unit 15 and calculates the total value of the hall information (step S5). The calculation method is as described above. The operating number calculation unit 14 refers to the operating number calculation standard using the total value of the hall information, and calculates the operating number (step S6). For example, assuming that the average waiting number is counted as the total value of the hall information, the number of operating units corresponding to the average waiting number is read from the correspondence table 53a shown in FIG.

  Here, the operating unit calculation unit 14 obtains the difference between the operating unit actual result and the provisional operating unit target, and corrects the operating unit obtained in step S6 based on the difference (step S7). That is, the current operating number is corrected according to the actual number of operating units. Specifically, for example, when there is a difference such that the actual number of operating units exceeds the provisional operating unit target by 10% or more, a correction is made such that the current operating number is -1.

  Finally, the operating unit calculation unit 14 updates the operating unit result by adding (operating unit x operating unit update interval / average car operating unit calculation period) to the current operating unit result (step S8).

-Extended function The power saving target may be automatically updated according to a preset rule. As a rule, for example, when the average unanswered time from when a hall call is registered until the assigned car (the car to which the hall call is assigned) arrives exceeds a threshold (for example, 15 seconds), the driving service is For example, the power saving target is reduced by 10% because it is determined that the power consumption has decreased too much.

  The operating unit calculation standard may be automatically updated based on the operating results. For example, when calculating the number of operating units using the above equation (2), if the average non-response time falls below the first threshold (for example, 5 seconds), the value of α is reduced by 10%, and the average non-response time When the value exceeds the second threshold value (for example, 15 seconds), the value of α is increased by 10%.

  In the explanation so far, it is assumed that a plurality of elevators (cars) installed within a certain range are managed as one group. However, a plurality of elevator groups in a building or all elevators are managed. It is possible to treat virtually as one group and control the number of operating units by the method described so far. At this time, for example, a restriction may be set such that the number of operating units is at least one per group.

  Further, the number of operating units may be corrected using user attribute information (wheelchair user, VIP, etc.). For example, when a person in a wheelchair is waiting for an elevator at a landing, or when a specific user is waiting for an elevator at a landing, the number of operating units is corrected to +1. User attribute information can be obtained by, for example, analyzing a camera image when the camera is used as the hall information detection devices 3a, 3b.

  Further, attribute information may be acquired using RFID. Further, wheelchair buttons, VIP buttons, and the like may be provided in the hall call registration devices 2a, 2b..., And user attributes may be determined from signals from these buttons.

-Special rules in allocation control The following special rules may be used to allocate hall calls on each floor to the cars 4a, 4b,. With these special rules, serviceability to elevator users can be enhanced.

  (1) The number of waiting people on each floor is counted at a fixed period (for example, 1 second), and when there is a floor where the waiting number exceeds a predetermined threshold, each of the cars 4a, 4b,. The assignment of hall call information is controlled so that either one is responded.

  As the threshold value, a value common to all floors or a different value for each floor may be arbitrarily set by an operation of a maintenance worker. Further, it may be a value that changes in accordance with the distribution of waiting numbers for each floor. For example, based on the deviation value, a value that preferentially assigns to a floor with a larger number of waiters than other floors is set.

  (2) The waiting time (maximum waiting time or average waiting time) of each floor is totaled at a fixed period (for example, 1 second), and when the waiting time exceeds a predetermined threshold, each car is preferentially placed on that floor. The allocation of hall call information is controlled so that any one of 4a, 4b.

  As the threshold value, a value common to all floors or a different value for each floor may be arbitrarily set by an operation of a maintenance worker. Further, it may be a value that changes in accordance with the distribution of waiting numbers for each floor. For example, a value that preferentially assigns to a floor having a longer waiting time than other floors based on the deviation value is set.

  As a priority allocation method, for example, for a car assigned a priority floor landing call, a method of canceling part or all of the other floor landing calls, or allocation of the floor in the allocation control algorithm Any method such as a method of increasing the priority parameter may be used.

  Here, the method of simply increasing the number of operating units when the number of users is large and decreasing the number of operating units when the number of users is small does not always save energy when there are many users. In the following, “energy saving” means “power saving”.

  In the method of the present invention, energy saving can be achieved without fail because the number of operating cars is increased / decreased by limiting the achievement of a medium / long-term power saving target such as 30 minutes or 1 hour. In addition, since real-time hall information using a camera or the like is used, it is possible to accurately grasp the waiting time of the user at the present time and to minimize a decrease in driving service.

This is shown in FIG.
FIG. 4 is a diagram showing a method of increasing / decreasing the number of elevators operated by this system in comparison with the conventional method. Consider the case where the number of elevator users changes as shown in FIG. In the conventional method, as shown in FIG. 5B, when the number of elevator users increases, the number of operating cars (elevators) is increased and operated. For this reason, the actual number of operating units may exceed the target number of operating units, which may not save energy. On the other hand, as shown in FIG. 5C, in the method of the present invention, since the medium- and long-term power saving target is limited, the number of operating units is gradually reduced, and energy saving can be achieved.

  In addition, there is a method of estimating the number of elevator users based on the loading capacity of the car, increasing the number of operating units when the number of users is large, and decreasing the number of operating units when the number of users is small. However, it is not possible to detect the number of people waiting at the landing in real time with the loading capacity of the car. For this reason, for example, even if it is found that the number of users is large from the loaded load after the response of the car and the number of operating cars is increased, the waiting time of the users remaining at the landing is not improved.

  Also, even if the number of users is found to be small from the loading load and the number of operating units is reduced, the timing at which the number of users actually decreases and the timing at which the number of operating units is reduced are shifted. Will run wastefully and will not save energy.

  That is, the same applies to an elevator equipped with a landing destination floor registration device capable of registering a destination floor at the landing. The current number of users cannot be detected in real time unless the user has registered the destination floor by operating the landing destination floor registration device. Therefore, even if the number of operating units is increased or decreased by using the landing destination floor registration device, the timing may be shifted and the energy saving effect may not be obtained.

  In the method of the present invention, for example, the number of users waiting at the landing using a camera is accurately detected in real time to increase or decrease the number of operating units. Therefore, it can operate | move with the number of operation according to the actual number of users, and energy saving can be achieved reliably, without reducing a driving service.

  This is shown in FIG.

  FIG. 5 is a diagram showing the timing of increasing / decreasing the number of elevators operated by this system in comparison with the conventional system. Consider the case where the number of elevator users changes as shown in FIG. In the conventional method, as shown in FIG. 5B, after the number of elevator users increases, the operating number is increased (see (1) in the figure). For this reason, the operation number with respect to the current number of users is insufficient, and the operation service is reduced. Also, after the number of users decreases, the number of operating units will be decreased. For this reason, a car will be used wastefully and it will not save energy.

  On the other hand, as shown in FIG. 5C, in the method of the present invention, the number of waiting passengers at the hall is detected in real time using a camera or the like, so that the operating number can be increased immediately when the number of users increases. The driving service does not decrease (see (3) in the figure). In addition, the number of operating units can be reduced immediately at the timing when the number of users decreases, and power is not wasted (see (4) in the figure).

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

  In the second embodiment, in addition to the configuration of the first embodiment, future platform information at the present time is predicted based on past platform information and in-building information, and the prediction result is reflected in the number of operating vehicles. It is a thing.

  FIG. 6 is a block diagram showing the configuration of the elevator group management system according to the second embodiment. In addition, the same code | symbol is attached | subjected to the same part as the structure of FIG. 1 in the said 1st Embodiment, and the detailed description shall be abbreviate | omitted.

  In the second embodiment, the group management control device 11 is provided with a past hall information storage unit 54, a hall information prediction unit 17, and an in-building information acquisition unit 18 in addition to the configuration of the first embodiment. .

About the past hall information storage unit 54 The past hall information storage unit 54 stores the hall information of each floor obtained by the hall information acquisition unit 15 in association with a time zone, a day of the week, and the like. The hall information includes information about halls on each floor including the number of waiting users and waiting time.

-About the hall information prediction part 17 The hall information prediction part 17 is based on the past hall information memorize | stored by the past hall information memorize | stored in the past hall information storage part 54 in the past, or the in-building information acquisition part 18, and present future The landing information is predicted, and the result is given to the operating number calculation unit 14. As a result, the operating number calculation unit 14 calculates the number of operating cars in consideration of not only the current landing information but also the prediction result of future landing information.

  For example, when the current waiting number is large and the number of waiting numbers is predicted to continue to be large after that, the number of operating cars is suppressed. In other words, if there are a large number of people waiting, the number of cars in operation will increase according to the method described above, but if there are many people waiting after that, the medium- to long-term power saving target will be achieved. Therefore, there is a possibility that the number of operating units will be extremely reduced from the middle. Therefore, when it is predicted that the number of waiting persons will continue to be large, the number of operating units is reduced from the conventional standard, and the waiting time of the elevator user from the present to the future is made uniform.

  As a prediction method, an existing statistical method may be used. For example, when the number of waiting persons at a certain time is predicted, an average value of waiting times at the same time in a certain past period is set as a predicted value. In addition, any method may be used, for example, the average value of the waiting time on the same day of the week and the same time in the past fixed period is used as the predicted value.

-In-building information acquisition unit 18 In addition to the hall information detection devices 3a, 3b ... installed at halls on each floor, sensors installed in offices and conference rooms are utilized. For example, consider a case where a sensor for measuring the number of people in a conference room is installed in a conference room on a certain floor. The number of people in the conference room is measured in real time and is counted by a building management system (for example, BEMS: building energy management system).

  The in-building information acquisition unit 18 acquires the number of people in the conference room subtotaled by the building management system as in-building information and gives it to the hall information prediction unit 17. Thereby, when the number of people in the conference room changes from a large number to a small number at a certain timing, the hall information prediction unit 17 moves the elevator after the predetermined time has passed after the reduced number of people (= the number of people who went out of the conference room). Predict that it will be used (that is, the number of people who have left the meeting room will be waiting).

  In such a configuration, as in the first embodiment, the number of cars in operation is controlled by limiting the achievement of a medium- to long-term power saving target. At that time, in addition to real-time landing information using a camera or the like, the number of operating vehicles is increased or decreased in consideration of past landing information and information in the building.

  The prediction accuracy of the hall information increases as past hall information is accumulated. In addition to the current waiting number, etc., by determining the number of operating units based on past landing information and considering the waiting number in the future, energy saving can be realized without deteriorating the driving service. Furthermore, if the operational form of the building and the tendency of user behavior are taken into account, it is possible to realize elevator operation and energy saving that are more suitable for the current situation.

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

  In the third embodiment, the effect of energy saving when operating by controlling the number of operating units by the method described in the first and second embodiments is visualized and displayed.

  FIG. 7 is a block diagram showing a configuration of an elevator group management system according to the third embodiment. In addition, the same code | symbol is attached | subjected to the same part as the structure of FIG. 1 in the said 1st Embodiment, and the detailed description shall be abbreviate | omitted.

  In the second embodiment, the group management control device 11 is provided with an energy saving effect display unit 19 and an energy saving effect simulation unit 20 in addition to the configuration of the first embodiment.

-About the energy saving effect display part 19 The energy saving effect display part 19 calculates the energy saving effect by control of the operating number of this system, and displays the result in a predetermined display form. The energy saving effect is calculated from the results of elevator operation (car load, operating distance, etc.). Or it is calculated | required by comparing the track record of the power consumption measured with a watt-hour meter, and the estimated value of the power consumption calculated from the simulation result calculated by the energy-saving effect simulation part 20. FIG.

  As a display method, as shown in FIG. 8, there is a method of displaying the energy saving effect calculated at regular intervals in a graph format. Similarly, it may be displayed in a table format. As shown in FIG. 9, the energy saving effect in the latest predetermined time may be displayed numerically. Although FIG. 9 shows an example in which the energy saving effect is displayed as a ratio, the power consumption amount may be displayed.

  Further, a result of simulating the energy saving effect when the power saving target setting is changed by the energy saving effect simulation unit 20 may be displayed. At the same time, numerical values related to serviceability such as an elevator user's waiting time and boarding time may be displayed in a form that can be easily recognized. FIG. 10 is an example in which the waiting time is displayed as a graph as an energy saving effect when the power saving target setting is changed.

・ About the energy-saving effect simulation unit 20 The energy-saving effect simulation unit 20 does not set a power-saving target based on past landing information and past elevator operation results (car load, driving distance, etc.). Case) or the simulation of the operation of the elevator when the power saving target is set to a value different from the actual set value to estimate the power consumption.

  As a simulation method, an elevator model prepared in advance may be used to estimate the number of users, driving distance, and the like, and an estimated value of power consumption may be calculated based on such information. Further, the estimated value of power consumption may be calculated by correcting the actual value of power consumption with the power saving target value.

  According to such a configuration, the effect of energy saving can be understood, and it can be used as a report of the energy saving results, as well as assisting in setting the power saving target and raising awareness of energy saving for the elevator user. Moreover, by simulating and displaying the energy saving effect when the power saving target setting is changed, it becomes possible to easily grasp the balance between the energy saving of the elevator desired by the building manager and the operation service time.

  According to at least one embodiment described above, there is provided an elevator group management system capable of realizing power saving by limiting the number of operating units reflecting real-time landing information in real time without deteriorating driving service. be able to.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
