Description

  The present invention relates to an elevator group management control device that collectively manages operations of a plurality of elevators.

  In a building in which a plurality of elevators are installed, a group management control system that collectively manages the operations of the plurality of elevators is generally employed. In this group management control system, when a hall call is generated by operating the hall call button provided in the elevator hall on each floor of the building, an optimal elevator is assigned to the hall call and the elevator is assigned to the hall call generation floor. The control of “normal operation mode” to be directed is implemented.

  As a method of selecting the most suitable elevator for hall calls, it is common to calculate the expected time until each elevator reaches the floor where the hall call occurs and select the elevator with the lowest expected time as the optimum elevator. Has been adopted.

  In addition to the “normal operation mode” described above, when elevator demand increases during morning work hours, evening work hours, and lunch hours, and when demand decreases during nights and holidays, etc. In some cases, a specific operation mode for controlling the elevator in accordance with a change in demand unique to the building may be employed.

  For example, in the elevator group management control method described in Patent Document 1, a semi-attendance time zone is set at a predetermined time before the attendance time zone, and each elevator is set in a predetermined pattern in the semi-attendance time zone. Distributed on each floor.

Furthermore, in another operation mode, during the morning work hours, for example, the demand for elevators in the UP (upward) direction increases from the standard floor such as the first floor where the entrance of this building is provided. It is controlled in an optimal way to accommodate the quantity. In other words, during work hours, all elevators that have finished answering the final call will be pulled back to the standard floor without waiting for the floor that has finished answering the final call, and will immediately respond to hall calls on the standard floor. I am waiting at the standard floor so that I can do it.
JP-A-4-371465

  However, if all elevators that have finished answering the final call during work hours are pulled back to the standard floor, calls on the standard floor can be answered immediately, but halls on the upper floor other than the standard floor Service will be worse for calls.

  In recent years, the number of companies that have introduced the flextime system has increased, and the demand for the standard floor during work hours has also been diversifying, so that it is no longer necessary to return all elevators to the standard floor during work hours.

  The present invention has been made in view of such circumstances, and elevator group management control that can improve services for customers on floors other than the reference floor without deteriorating services for users on the reference floor. An object is to provide an apparatus.

  In order to solve the above-mentioned problem, the present invention recalls an elevator in a state where a call is not assigned to a standard floor where demand for elevators is high in a specified work time period in a building where a plurality of elevators are installed. A working time zone operation mode in which each elevator that has been recalled in turn departs from the standard floor, and a normal operation mode in which an optimal elevator is assigned to the hall call that occurs on each floor and the elevator is directed to the hall call generation floor. In the elevator group management control device, the demand amount detecting means for detecting the demand amount for the elevator on the reference floor in the working time zone operation mode, and the elevator amount based on the demand amount detected by the demand amount detecting means. The number of recalling units that determines the number of recalling units to the reference floor and the unit determined by the number of recalling units And a recall command output means for outputting a recall command to the standard floor to minute elevator.

  In the elevator group management control device configured as described above, in the working hours operation mode, the number of elevators to be returned to the reference floor is determined based on the demand for elevators on the reference floor, so that it responds to the final call. Only the necessary number of all finished elevators will be recalled to the standard floor. Therefore, the service for elevator users on the standard floor does not deteriorate. Furthermore, for hall calls on floors other than the standard floor, elevators that have not been called back to the standard floor can respond quickly, so the service for passengers on floors other than the standard floor can be improved. .

  In another aspect of the invention, the demand amount detection means in the elevator group management control device of the invention described above is measured by the passenger number detection means for measuring the number of passengers who have entered the elevator from the reference floor, and the passenger number detection means. Passenger counting means for accumulating the number of passengers for the past several minutes. The recalling number determining means determines the number of recalling to the reference floor of the elevator based on the number of passengers for the past several minutes accumulated by the passenger number counting means in the demand amount detecting means.

  In the elevator group management control device configured as described above, the number of elevators that are called back to the reference floor is determined by the number of elevator passengers in the past several minutes, so that more elevators than necessary are called back to the reference floor. Absent.

  In another aspect of the invention, the demand amount detection means in the elevator group management control device of the invention described above is measured by the passenger number detection means for measuring the number of passengers who have entered the elevator from the reference floor, and the passenger number detection means. It has passenger number statistics means for collecting the number of passengers for each day of the week and time zone. The recalling number determining means determines the number of recalling to the reference floor of the elevator based on the number of passengers in the current day of the week and time zone collected by the passenger number statistics means in the demand amount detecting means.

  In the elevator group management control device configured as described above, the number of elevators that are called back to the reference floor is determined based on the statistically tabulated number of passengers in the current day of the week and time zone. Will not be recalled to the reference floor.

  In another invention, the elevator group management control device of the above-described invention further counts the total unanswered time indicating the time until the elevator arrives for the hall call on the reference floor for the past several minutes. A non-response time registration means for recording is added. Then, when the total number of non-response times recorded by the non-response time registration means exceeds a specified time, the number-of-recalling number determination means corrects the increase in the number of recalled elevators to the reference floor.

  In the elevator group management control device configured in this way, it takes a long time for the elevator that has started from the reference floor to finish responding to the final call, and when there is no elevator waiting on the reference floor, The passenger (user) on the reference floor presses the hall call button and waits for the elevator to arrive. The total time of unanswered time which is the arrival waiting time of this elevator increases. When the total time of the unanswered time exceeds the specified time, the number of elevators that have been previously returned to the reference floor is corrected to be increased. Therefore, the service for elevator users on the standard floor is further improved.

  In another invention, a congestion degree detecting means for detecting the degree of congestion of elevator waiting personnel in the elevator hall on the standard floor is further added to the elevator group management control apparatus of the above-described invention. Then, when the congestion level detected by the congestion level detection unit exceeds a specified value, the recall number determination unit corrects the increase in the number of recalls to the reference floor of the determined elevator.

  In the elevator group management control apparatus configured as described above, when the number of passengers on the reference floor increases, there is no elevator waiting on the reference floor. In this case, the number of personnel waiting for the elevator on the reference floor further increases. In such a case, the number of recalled elevators to the reference floor determined previously is corrected to increase. Therefore, the service for elevator users on the standard floor is further improved.

  Further, another invention is directed to the elevator group management control device according to the above-described invention, and further to the elevator that does not call back to the reference floor, a distributed command that outputs a command to wait for distribution to a floor other than the reference floor. An output means is added.

  In the elevator group management control device configured as described above, it is possible to further improve the service for the passengers on the floor other than the reference floor.

  In the present invention, in the attendance time zone operation mode, the number of elevators to be returned to the reference floor is determined based on the demand for elevators on the reference floor.

  Therefore, the service for elevator users on the standard floor does not deteriorate. Furthermore, for hall calls on floors other than the standard floor, elevators that have not been called back to the standard floor can respond quickly, so the service for passengers on floors other than the standard floor can be improved. .

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

(First embodiment)
FIG. 1 is a schematic diagram showing an elevator system in which an elevator group management control device according to a first embodiment of the present invention is incorporated.

  In the elevator system of this embodiment, a group management control device 1 that performs group management control of six elevators from A to F, and six car control devices 2 that individually control the operation of each elevator. And six cars 3 for carrying passengers in each elevator. In each car 3, there is provided a car call button 4 in which a passenger who has boarded the car 3 registers his / her destination floor.

  On the other hand, a hall call button 6 for a user (passenger) waiting for the elevator to call the elevator is attached to the elevator hall on each floor 5 of the building where the elevator system is provided. In this embodiment, the entrance / exit of this building is provided among the plurality of floors 5 constituting the building, and the first floor with the highest demand for elevators in the morning work hours is defined as the reference floor 5a.

  For example, in the group management control device 1 of the first embodiment configured by a computer or the like, an operation mode setting unit 7, a call registration unit 8, an assignment control unit 9, a passenger number detection unit 10, a passenger number counting unit 11, a call back A number determination unit 12, a recall number table 13, and a recall command output unit 14 are provided.

  The operation mode setting unit 7 sets “normal operation mode” or “attendance time zone operation mode” for the car control device 2 of each elevator.

  In the “normal operation mode”, when the hall call generation by the button operation of the hall call button 6 provided in the elevator hall on each floor 5 is registered in the call registration unit 8, the allocation control unit 9 responds to the hall call. This is an operation mode in which an optimal elevator is allocated and the elevator is directed to the hall call generation floor. As mentioned above, as a method to select the most suitable elevator for hall calls, calculate the expected time until each elevator reaches the hall call occurrence floor and select the elevator with the lowest expected time as the optimum elevator It is generally adopted to do. In calculating the estimated time, the time required for the elevator to stop at the floor 5 designated by the car call is also included.

  In the “commuting time zone operation mode”, the elevator in a state in which no call is assigned to the reference floor 5a is called back to the reference floor 5a in a specified attendance time zone such as from 8:00 to 9:00 in the morning. This is an operation mode in which each elevator that has been recalled is temporarily made to wait on the reference floor 5a, and each waiting elevator is forcibly made to wait for a predetermined time such as 10 seconds in a door open state, and then starts from the reference floor 5a. . Therefore, when the door of the first elevator opens and a passenger gets on the door, the door automatically closes, and the corresponding elevator departs from the reference floor 5a. After that, the door of the second elevator waiting is opened. It should be noted that the number of recalled elevators in a state where no call is assigned to the reference floor 5a is determined by the recalled number determining unit 12.

  Even during the “commuting time zone operation mode” period, an optimal elevator in an elevator other than the elevator that is called back to the reference floor 5a and is on standby is assigned to the hall call generated on each floor 5, and the elevator is assigned to the hall. Move to the calling floor.

  The call registration unit 8 registers the hall call by the button operation of the hall call button 6 provided on each floor 5 and the car call by the button operation of the car call button 4 provided on each car 3, and the assignment control unit 9 To send.

  The allocation control unit 9 allocates an optimal elevator considering the car call to each hall call generated on each floor 5, and sends an instruction to direct the elevator to the hall call generation floor to the elevator car control device 2 To do.

  The number-of-passengers detection unit 10 estimates the number of passengers from the load increase in each car 3 on the reference floor 5a during the “commuting time zone operation mode” period, and counts the number of passengers as the number of passengers from the reference floor 5a to each elevator. Send to unit 11. The number of passengers totaling unit 11 adds the number of passengers to each elevator sent from the number of passengers totaling unit 11 to obtain the number of passengers to all the elevators, and the number of passengers to all the elevators, for example, for the past 5 minutes Are summed up and sent to the recalled number determining unit 12 as the number of passengers on the elevator from the reference floor 5a for the past 5 minutes.

  In the recalled number table 13, as shown in FIG. 2, the number of recalled items to the reference floor 5a of the elevator is stored for each range of the number of passengers (passenger accumulated value) for the past 5 minutes. The number of recalls is the rated load of each car 3, the number of elevators, the elevator speed, the number of building floors, the service improvement ratio on the reference floor 5a and the upper floor (the unanswered time on the reference floor and the unanswered on the upper floor) Time priority ratio).

  The recalled number determination unit 12 reads and determines the number of recalls corresponding to the number of passengers for the past 5 minutes input from the number-of-passengers counting unit 11 during the “commuting time zone operation mode” period, and determines this number. The determined recall number is sent to the recall command output unit 14.

  The call back command output unit 14 detects, from the call assignment state of each elevator of the assignment control unit 9, an elevator in which no call is assigned at the current time point, and from among the elevators in which this call is not assigned Select elevators for the number of recalled units determined earlier. Then, the recall command output unit 14 outputs a recall command to the reference floor 5a to the car control device 2 of each selected elevator.

  FIG. 3 is a flowchart showing the operations of the passenger number detection unit 10, the passenger number counting unit 11, the recall number determination unit 12, and the recall command output unit 14.

  If the amount of elevator demand going from the reference floor 5a to the upper floor becomes extremely large when the time is in the working hours, the “going hours operating mode” is set (S1). When the attendance time zone operation mode is set, the number of passengers from the reference floor 5a for the past five minutes is measured by the number-of-passengers counting unit 11 (S2). According to the measurement result, the number of recalls to the reference floor 5a is determined according to the recall number table 13 of FIG. 2 (S3).

  When the number of recalls is determined, the recall command output unit 14 outputs a recall command to the reference floor 5a for the elevators corresponding to the number of recalls (S4), and the corresponding number of elevators are recalled to the reference floor 5a.

  In the elevator group management control device of the first embodiment configured as described above, the number of elevators recalled to the reference floor 5a according to the number of passengers (demand) who have been on the elevator in the past five minutes on the reference floor 5a. Is determined. In this way, only the required number of all elevators that have finished responding to the final call are called back to the reference floor 5a.

  Therefore, the service for elevator users on the reference floor 5a does not deteriorate. Furthermore, for hall calls on floors 5 other than the standard floor, elevators that have not been called back to the standard floor 5a can respond promptly, so that passengers on floors 5 other than the standard floor 5a Service can be improved.

(Second Embodiment)
FIG. 4 is a schematic diagram showing an elevator system in which an elevator group management control apparatus according to the second embodiment of the present invention is incorporated. The same parts as those of the elevator system in which the elevator group management control device 1 according to the first embodiment shown in FIG. 1 is incorporated are denoted by the same reference numerals, and detailed description of the overlapping parts is omitted.

  In the elevator group management control device 1a of the second embodiment, an operation mode setting unit 7, a call registration unit 8, an allocation control unit 9, a passenger number detection unit 10, a passenger number counting unit 11, a passenger number statistics unit 15 are provided. , A statistical data table 16, a recall number determination unit 12a, a recall number table 13a, and a recall command output unit 14 are provided.

  The passenger number statistics unit 15 collects the number of passengers in the past one minute measured by the passenger number detection unit 10 and totaled by the passenger number totalization unit 11 for each day of the week and time zone, and writes it in the statistical data table 16. At the same time, the statistical data value of the number of passengers written in the statistical data table 16 is updated.

  In the statistical data table 16, as shown in FIG. 5, the statistical data value Data () of the number of passengers for each 10-minute time slot in the working hours from 8:00 to 9:00 on each day of the week from Monday to Sunday. x, y) are stored. Here, x indicates a day of the week, and y indicates a time zone every 10 minutes.

  In the recalled number table 13a, as shown in FIG. 7, for each range of the statistical data value Data (x, y) of the number of passengers for each 10-minute time zone stored in the statistical data table 16. The number of elevators to the reference floor 5a is stored. The number of recalls is the rated load of each car 3, the number of elevators, the elevator speed, the number of building floors, the service improvement ratio on the reference floor 5a and the upper floor (the unanswered time on the reference floor and the unanswered on the upper floor) Time priority ratio).

  Then, the passenger number statistics unit 15 updates the statistical data value Data (x, y) of the number of passengers for each 10-minute time zone in the statistical data table 16 shown in FIG. 5 according to the flowchart of FIG. In FIG. 6, only the case of collecting statistical data from 8:10:00 to 8:19:59 on Monday will be described.

  When the time is a working time zone from 8 o'clock and the demand for elevators from the reference floor 5a to the upper floor is remarkably increased, the “working time zone operation mode” is set (S21). The number of passengers in the elevator is measured from the reference floor 5a in a preset time zone (for example, Monday, 8:10: 00 to 8:19:59) by the number of passengers detection unit 10 (S22), and the number of passengers counting unit 11, the number of passengers M per minute is calculated (S23).

Number of passengers per minute (M) = N / 10 (person / minute)
* N: 10-minute measurement result (person)
The result (M) is added to the conventional statistical value and averaged, and updated as new statistical data (S24).

Data (0, 1) = (Data (0, 1) + M) / 2
In this way, the passenger number statistics unit 15 always changes the statistical data value Data (x, y) of the passenger number to the latest statistical data value Data (x, y) for each 10-minute time zone in the statistical data table 16. ) Will be updated.

  FIG. 8 is a flowchart showing the operation of the recall number determination unit 12a and the recall command output unit 14.

  If the demand for an elevator heading from the standard floor 5a to the upper floor becomes remarkably increased from 8 o'clock, the “attendance time zone operation mode” is set (S31). In the attendance time zone operation mode, the statistical data value Data (x, y) of the number of passengers corresponding to the current day of the week and time in the statistical data table 16 is referred to via the passenger number statistics unit 15 (S32). The number of recalls to the reference floor 5a corresponding to the statistical data value Data (x, y) is read from the recall number table 13a and determined (S33).

  When the number of recalls is determined, the recall command output unit 14 outputs a recall command to the reference floor 5a to the elevator car control device 2 corresponding to the number of recalls (S34), and the corresponding number of elevators are recalled to the reference floor 5a. .

  In the elevator group management control device of the second embodiment configured as described above, the number of elevators to be returned to the reference floor is the statistical data of the number of passengers for each 10-minute time zone on the current day of the week and the time zone. Since it is determined based on the value Data (x, y), an elevator more than necessary is not called back to the reference floor 5a. Therefore, it is possible to improve the service for the customers on the upper floor 5 other than the reference floor 5a without degrading the service for the customers on the reference floor 5a.

  The non-response time registration unit 17 measures and records the total time of the non-response time indicating the time until the elevator arrives for the hall call of the reference floor 5a for the past 5 minutes during the “commuting time zone operation mode” setting period. The total unanswered time is sent to the recall number determination unit 12b.

  Specifically, if there are many users during the “commuting time zone operation mode” setting period and all the waiting elevators have departed from the reference floor 5a and there are no waiting elevators, The hall call button 6 of 5a will be pushed. Each unanswered time until arrival of each elevator for each hall call generated by the operation of each hall call button 6 is calculated using each state of the call registration unit 8 and each car control device 2, and in the past 5 minutes Total over.

  The recalled number determination unit 12b is similar to the recalled number determination unit 12a in the second embodiment shown in FIG. 4, and the statistical data values Data (x, y) of the number of passengers corresponding to the current day of the week and time in the statistical data table 16 ) Corresponding to the reference floor 5a is read from the recall number table 13a and determined. Furthermore, when the total number of unanswered times in the past 5 minutes counted by the unanswered time registration unit 17 exceeds a predetermined time T determined in advance, the recall number determination unit 12b determines the reference floor 5a of the elevator previously determined. Correct the increase in the number of recalls to.
