Description

  The present invention relates to an elevator group management system having a plurality of elevators, and more particularly, to an elevator group management system in which each elevator is group-controlled under different service areas.

  In general, when an elevator is installed in an office building, the number of elevators installed is determined by calculating traffic demand and traffic flow (people flow) in the building such as usage and number of users. In particular, in the case of a high floor building, in order to reduce the waiting time, an elevator service area is often divided into a low-rise area and a high-rise area.

  For example, in a 40-story building, elevators from Units 1 to 6 respond to low-rise areas from 1F to 20F, and elevators from Units 7 to 12 respond to high-rise areas from 1F and 20F to 40F. It is something like that. In this case, since the elevator facilities are divided in advance for the low-rise area and the high-rise area, the elevator of No. 1-6 responds to 21F-40F, or the elevator of No. 7-12 responds to 2-19F It is physically impossible.

On the other hand, there is known a method in which an elevator service area is divided in accordance with the traffic demand of a building, and a plurality of elevators are divided and operated for each area (see, for example, Patent Document 1). According to this, it is possible to eliminate the concentrated traffic demand and improve the transportation capacity, and it is possible to alleviate the congestion at the time of work or lunch depending on the building.
Japanese Patent No. 3551618

  In the above-mentioned patent document 1, service areas are arbitrarily divided in one bank and each elevator is divided and operated, and each elevator can physically respond to all floors.

  However, in the elevator group management system in which the elevator facilities are divided into banks for low-rise and high-rise buildings, the service area of each elevator is fixed by each bank, so it cannot respond to floors in other banks . For this reason, after the building is completed, for example, if the traffic demand changes from the time of the elevator plan due to tenant changes or various change factors, the average waiting time is about 20 seconds in one bank and the average waiting time is 40 in the other bank. There may be an unbalanced state of waiting time in the building, such as about a second. In this case, an elevator of a bank having a low average waiting time is desired to be used for a bank having a long average waiting time, but this is physically impossible in a banked system.

  Accordingly, an object of the present invention is to provide a system in which a plurality of elevators are divided into banks, and when an unbalanced state occurs between the banks after the building is completed, the unbalanced state is not required without requiring a significant system change. An object of the present invention is to provide a group management system for elevators that can efficiently perform operation services by eliminating the state.

  The present invention provides an elevator group management system in which a plurality of elevators are managed by dividing them into at least two banks having different service areas, and a plurality of elevators under group management control are performed for each of the banks. Group management control means, an elevator capable of all floor service provided separately from each elevator corresponding to each bank, and information necessary for operation control of the elevator capable of all floor service And switching control means for controlling the operation of the elevator by giving to any of the means.

  According to the present invention, an elevator capable of providing all floor services provided separately from each elevator corresponding to each bank can be used by appropriately switching between the banks. As a result, in a system in which multiple elevators are divided into banks, if an unbalanced state occurs between each bank after the building is completed, the unbalanced state is eliminated without requiring a significant system change. Driving service can be performed efficiently.

Next, a second embodiment of the present invention will be described.
FIG. 3 is a block diagram showing an overall configuration of an elevator group management system according to the second embodiment of the present invention. In FIG. 3, the same parts as those in FIG. 1 in the first embodiment will be described with the same reference numerals.

  As shown in FIG. 3, the elevator group management control system 12 includes a group management control device 13 for a lower layer that performs group management control of the elevators 11 a to 11 f in the bank A, and a group of elevators 11 h to 11 m in the bank B. A high-level group management control device 14 that performs management control, a switching determination unit 22, and a switching control unit 15 are provided.

  The low layer group management control device 13, the high layer group management control device 14, and the switching control unit 15 are each configured by a computer. The low layer group management control device 13 is realized by a computer provided on the bank A side, and the high layer group management control device 14 is realized by a computer provided on the bank B side. Further, the switching control unit 15 and the switching determination unit 22 are realized by a computer provided between the bank A and the bank B.

  The lower layer group management control device 13 includes an allocation control unit 16a, a car call registration unit 17a, and a lower layer waiting time calculation unit 21a. The allocation control unit 16a calculates each evaluation value for the hall call on each floor in the bank A based on the status information of each elevator 11a to 11f, and sends an allocation signal to the low-rise elevator with the best evaluation value. Output. The car call registration unit 17a stores a car call generated by an operation of a destination floor designation button (not shown) installed in the car of each of the elevators 11a to 11f. The low-layer wait time calculating unit 21a calculates an average wait time for hall calls on each floor in the bank A (low-rise bank).

  The high-rise group management control device 14 includes an allocation control unit 16b, a car call registration unit 17b, and a high-rise waiting time calculation unit 21b. The allocation control unit 16b calculates each evaluation value for the hall call on each floor in the bank B based on the status information of each elevator 11h to 11m, and sends an allocation signal to the low-rise elevator with the best evaluation value. Output. The car call registration unit 17b stores a car call generated by an operation of a destination floor designation button (not shown) installed in the elevator cars 11h to 11m. The high-rise waiting time calculating unit 21b calculates an average waiting time for hall calls on each floor in the bank B (high-rise bank).

  The switching determination unit 22 compares the average waiting time of the bank A calculated by the low-layer waiting time calculating unit 21a with the average waiting time of the bank B calculated by the high-layer waiting time calculating unit 21b, It is determined whether the serviceable elevator 11g should be used for high-rise or low-rise use.

  Based on the determination result of the switching determination unit 22, the switching control unit 15 gives information necessary for operation control of the elevator 11 g capable of providing all floor service to the low-rise group management control device 13 or the high-rise group management control device 14. The elevator 11g is operated and controlled.

  In such a configuration, the average waiting time of the bank A is calculated by the low layer waiting time calculation unit 21a on the low layer group management control device 13 side. The waiting time is the time from when the user registers the hall call until the elevator arrives at the floor. This waiting time is the time elapsed since the hall call was registered (the time until the control device receives the hall call), and the estimated time until the elevator scheduled to respond to the hall call arrives at the floor. It is calculated by adding.

  Here, for example, if there are hall calls on 2F and 3F for 5 minutes and the waiting times are 10 seconds and 20 seconds, respectively, the average waiting time of bank A at that time is 15 seconds. The same applies to the high-level group management control device 14 side, and the average waiting time of the bank B is calculated by the high-layer waiting time calculating unit 21b.

  Here, the switching determination unit 22 compares the average waiting time of the bank A calculated by the low-layer waiting time calculating unit 21a with the average waiting time of the bank B calculated by the high-layer waiting time calculating unit 21b. The elevator 11g is assigned to the bank with the longer time.

For example, if the average waiting time of bank A in the past 5 minutes is K1, and the average waiting time of bank B is K2,
K1 <K2
In this case, it is determined that it is optimal to use the elevator 11g as a high-rise elevator.

  In addition, as a determination criterion at this time, in addition to the average waiting time, a maximum waiting time (maximum waiting time in each hall call) or a response rate of 60 seconds or more (wait time in each hall call is 60 seconds). It is also possible to use a response rate (a ratio of the number of hall calls in which the waiting time exceeds 30 seconds among all hall calls) or the like.

  When the switching determination unit 22 determines that the use for the high rise is optimal, the switching control unit 15 switches the operation of the elevator 11g to the high rise in response to the determination result. After switching, the state information and car call information of the elevator 11g are transmitted to the high-rise group management control device 14. As a result, when a hall call is registered on each floor in bank B, the high-rise group management control device 14 selects the elevator with the best evaluation value from the seven elevators 11g to 11m, and outputs an allocation signal. . On the other hand, for the hall call registered on each floor in bank A, the low-level group management control device 13 selects the elevator with the best evaluation value from the six elevators 11a to 11f, and outputs an allocation signal. To do.

  As described above, according to the second embodiment of the present invention, in the elevator group management system divided into the low-rise bank and the high-rise bank, the deviation of the waiting time of the hall call is detected in the low-rise bank and the high-rise bank, and the waiting By using an elevator capable of providing all floor services in a bank with a large amount of time, an unbalanced state between the low-rise bank and the high-rise bank can be eliminated, and an efficient operation service can be performed.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described.
FIG. 5 is a block diagram showing the overall configuration of an elevator group management system according to the fourth embodiment of the present invention. In FIG. 5, the same parts as those in FIG. 1 in the first embodiment will be described with the same reference numerals.

  As shown in FIG. 5, the elevator group management control system 12 includes a group management control device 13 for a lower layer that performs group management control of the elevators 11 a to 11 f in the bank A, and a group of elevators 11 h to 11 m in the bank B. A high-level group management control device 14 that performs management control, a maximum waiting time selection unit 25, and a relief control unit 26 are provided.

  The low layer group management control device 13, the high layer group management control device 14, and the switching control unit 15 are each configured by a computer. The low layer group management control device 13 is realized by a computer provided on the bank A side, and the high layer group management control device 14 is realized by a computer provided on the bank B side. In addition, the maximum waiting time selection unit 25 and the relief control unit 26 are realized by a computer provided between the bank A and the bank B.

  The lower layer group management control device 13 includes an allocation control unit 16a, a car call registration unit 17a, and a lower layer waiting time calculation unit 24a. The allocation control unit 16a calculates each evaluation value for the hall call on each floor in the bank A based on the status information of each elevator 11a to 11f, and sends an allocation signal to the low-rise elevator with the best evaluation value. Output. The car call registration unit 17a stores a car call generated by an operation of a destination floor designation button (not shown) installed in the car of each of the elevators 11a to 11f. The low-layer waiting time calculation unit 24a calculates a waiting time for a hall call on each floor in the bank A (low-rise bank).

  The high-rise group management control device 14 includes an allocation control unit 16b, a car call registration unit 17b, and a high-rise waiting time calculation unit 24b. The allocation control unit 16b calculates each evaluation value for the hall call on each floor in the bank B based on the status information of each elevator 11h to 11m, and sends an allocation signal to the low-rise elevator with the best evaluation value. Output. The car call registration unit 17b stores a car call generated by an operation of a destination floor designation button (not shown) installed in the elevator cars 11h to 11m. The high-rise waiting time calculating unit 24b calculates a waiting time for a hall call on each floor in the bank B (high-rise bank).

  The maximum waiting time selection unit 25 includes the waiting time of each floor in the bank A calculated by the low layer waiting time calculation unit 24a and the waiting time of each floor in the bank B calculated by the high layer waiting time calculation unit 24b. Select the floor with the longest waiting time.

  When the waiting time of the hall call of the floor selected by the maximum waiting time selection unit 25 is equal to or greater than a preset value (for example, 30 seconds), the relief control unit 26 applies all floors to the hall call of the floor. A serviceable elevator 11g is made to respond.

  In such a configuration, on the low layer group management control device 13 side, the low layer waiting time calculation unit 24a calculates the waiting time (elapsed time + predicted arrival time) of each floor in the bank A. For example, when the elapsed time after the hall call is registered is 10 seconds and the estimated time until the elevator scheduled to respond to the hall call arrives is 15 seconds, the waiting time is 25 seconds. This is performed for each floor in bank A. The same applies to the high-level group management control device 14 side, and the high-layer waiting time calculating unit 24a calculates the waiting time (elapsed time + predicted arrival time) of each floor in the bank B.

The floor with the maximum number of passengers within a certain time (for example, 60 seconds) is selected. For example, if the number of passengers on the 2nd floor in Bank A is the largest at 25 people, and the number of passengers on the 40th floor in Bank B is the largest at 26 people, 40F in Bank B is selected.

  When the waiting time value of the hall call of the floor selected by the maximum waiting time calculating unit 12 is equal to or greater than a preset value (for example, 30 seconds), the relief control unit 13 sends the floor 11 to the elevator 11g capable of providing all floor services. The hall call assignment signal is output and responded.

  Note that the condition for causing the elevator 11g to respond is not limited to the comparison of only the waiting time value, but may be a composite condition such as “waiting time> 30 seconds and predicted arrival time> 15 seconds”.

  As described above, according to the fourth embodiment of the present invention, in the elevator group management system divided into the low-rise bank and the high-rise bank, the elevator capable of all-floor service is responded to the floor where the long wait has occurred. By doing so, it is possible to alleviate the long waiting state occurring in one bank, and as a result, eliminate the unbalanced state between the low-rise bank and the high-rise bank and perform an efficient operation service.

Output. The car call registration unit 17b stores a car call generated by an operation of a destination floor designation button (not shown) installed in the elevator cars 11h to 11m. The high-passenger passenger number measuring unit 27b measures the number of passengers who ride in the elevator elevators 11h to 11m from each of the banks B.

  The maximum occupant number selection unit 28 receives the measurement results of the low-rise occupant number measurement unit 27a and the high-rise occupant number measurement unit 27b, and selects the floor having the maximum number of occupants within a predetermined time.

  When the number of passengers on the floor selected by the maximum passenger number selection unit 28 is equal to or greater than a preset value, the relief control unit 26 causes the elevator 11g capable of all floor services to respond to the hall call on the floor. .

  In such a configuration, on the low-level group management control device 13 side, the number of passengers boarding from each floor in the bank A is measured by the low-level passenger number measuring unit 27a. This uses, for example, a method of measuring the number of passengers using a load sensor from a value obtained by subtracting the load value at the time of departure from the load value at the time of landing. As another method, two sets of optical sensors may be provided at the entrance / exit of the car, and the number of passengers may be measured from the difference in detection timing of the two sets of optical sensors. Furthermore, an image recognition technique or the like may be used. In the present invention, the measurement method is not particularly limited. The same applies to the high-rise group management control device 14 side, and the number of passengers boarding from each floor in the bank B is measured by the high-rise passenger number measuring unit 27b.

  The maximum number of passengers selection unit 28 is within a certain time (for example, 60%) among the number of passengers on each floor measured by the low-rise passenger measurement unit 27a and the number of passengers on each floor measured by the high-rise passenger measurement unit 27b. Select the floor with the largest number of passengers. For example, if the number of passengers on the 2nd floor in Bank A is the largest at 25 people, and the number of passengers on the 40th floor in Bank B is the largest at 26 people, 40F in Bank B is selected.

  In the relief control unit 26, when the number of passengers on the floor selected by the maximum passenger number selecting unit 28 is equal to or greater than a preset value (for example, 20 people), it is determined that there is a person who could not get on the elevator on that floor. To do. Then, an allotted floor responding elevator 11g is caused to respond by outputting an allocation signal for the hall call on the floor. In the above example, the elevator 11g is made to respond to the call of 40F of the bank B.

  As described above, according to the fifth embodiment of the present invention, in the elevator group management system divided into the low-rise bank and the high-rise bank, the elevator capable of providing all-floor service is caused to respond to the floor having the largest number of passengers. Thus, it is possible to alleviate the waiting state caused by the unoccupied state occurring in one bank, and as a result, eliminate the unbalanced state between the low-rise bank and the high-rise bank and perform an efficient driving service.

  In each of the above-described embodiments, the description has been made on the assumption that the system is divided into two, ie, the low-rise bank and the high-rise bank. However, the configuration of the bank division is not limited to this. A divided configuration may be used.

  Moreover, the elevator which can provide all floor service provided separately from the elevator in each bank is not restricted to one, and may be two or more.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. In addition, various forms can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components may be omitted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
