2. Operation of Elevator System (1) Overview of Conventional Elevator System In an elevator system, an elevator provided with an entrance on each of a front surface and a back surface may be used. Conventionally, this elevator is mainly used in a parking lot or a backyard of a store, but its purpose of use has been limited.

  In this Embodiment, it makes it a subject to improve the elevator system which has an elevator with which the entrance was each provided in the front and back, and to improve a transport capability and a user's convenience.

(2) Overview of the operation of the elevator system according to the present embodiment The group management control device 10 according to the present embodiment receives six registered calls each time a call is registered by the call registration device 20 arranged at the landing. Assign to the entrance of any one of the elevators. In addition, when the group management control device 10 distributes and assigns a plurality of calls registered on one floor to the front entrance and the rear entrance of one elevator, when one elevator arrives at one floor In accordance with a predetermined control law, only the call assigned to one entrance is answered and only the door corresponding to one entrance is opened, and for the call assigned to the other entrance, the next lap Thereafter, only the door corresponding to the other entrance is opened in response.

  In addition, you may memorize | store the movement time table which prescribed | regulated the movement time from the call registration apparatus 20 to each entrance in the memory | storage part 12 of the group management control apparatus 10. FIG. In this case, when a call is registered by the call registration device 20, the group management control device 10 refers to the travel time table stored in the storage unit 12 and determines the entrance that the user can reach before the elevator starts. assign. In addition, when it is not in time for the departure of the elevator, the door opening state may be maintained to delay the departure of the elevator.

  FIG. 6 is a diagram showing an example of the travel time table. In the example of the movement time table of FIG. 6, each movement time between the two call registration devices 20 and the twelve entrances A1 to D3 is defined. These travel times are set based on the distance between the two call registration devices 20 and the twelve entrances A1 to D3 and the walking speed of a general user.

3. Specific Operation of Elevator System Hereinafter, the operation according to the present invention among the operations of the elevator system will be specifically described.

  FIG. 7 is a flowchart showing an example of call allocation control operation. The processing of this flowchart is executed at a predetermined cycle.

  The group management control device 10 determines whether or not a new landing destination floor call has been registered (S11).

  When a new landing destination floor call is not registered (NO in S11), the group management control device 10 ends the process of this flowchart.

  When a new landing destination floor call is registered (YES in S11), the group management control device 10 performs a normal destination floor call assignment process for the new landing destination floor call (S12). The normal destination floor call assignment processing is processing for assigning a destination floor to any one of a plurality of elevators (units) based on a change in waiting time or service completion time. In the normal destination floor call assignment process, various known assignment methods can be applied. The same applies to other flowcharts described later.

  The group management control device 10 determines whether or not the direction of the new call is upward (S13).

  If the direction of the new call is upward (YES in S13), the group management control device 10 assigns a front entrance (S14).

  On the other hand, when the direction of the new call is not upward, that is, downward (NO in S13), the group management control device 10 assigns a rear entrance (S15).

  The group management control device 10 displays the assigned entrance identification symbol on the call registration device 20 (S16). Specifically, the group management control device 10 transmits allocation result information including the assigned entrance identification symbol to the call registration device 20, and the call registration device 20 performs allocation based on the received allocation result information. An entrance identification symbol is displayed on the display unit 24.

  The group management control device 10 transmits the assigned information (front entrance / back entrance (straight back)) together with the new call information (departure floor / destination floor) to the elevator control device 30 of the assigned number (S17).

4). Conventional Problems and Effects of the Present Embodiment (1) Conventionally, except for the uppermost floor and the lowermost floor, calls in both upward and downward directions are assigned to one entrance. There was a problem like this.
a) It is necessary for the user to get on after confirming whether the arrived elevator is an elevator in the direction to which he or she is heading.
b) Because there are users for both upward and downward calls in the elevator hall, that is, there are users who do not get on when the next elevator arrives. When boarding, it must pass between users who do not board, and smooth boarding may be inhibited.
c) There is a case where an elevator that departs in the reverse direction is erroneously boarded.

  However, in this embodiment, since only one of the upward and downward calls is assigned to one entrance, when the elevator opens in response, a) all users are It is possible to get on unconditionally, b) erroneously getting on an elevator that departs in the opposite direction, and c) getting on smoothly.

(2) FIG. 8 is a diagram showing the operation status of the elevator when there is an underground floor. Conventionally, in the hall destination floor registration system, if you do not install hall lanterns (the hall direction indicator lights), the hall destination floors in different directions with the same floor as the departure floor in order to prevent mistakes in getting on the elevator in the reverse direction Control may be performed so that calls are not assigned to the same elevator. In this case, since the elevators to be allocated are limited, it is impossible to select an elevator suitable for allocation, and there is a problem that transportation efficiency is reduced. In particular, in a building having an underground floor, the above problem is likely to be conspicuous when assigning a call to the lobby floor. For example, as shown in FIG. 8, for an elevator to which a downward call is assigned on the lobby floor, the assignment of the upward call is restricted in order to prevent erroneous passengers from the upward call. There was a need.

  However, in the present embodiment, the upward call is assigned to the front entrance, and the downward call is assigned to the back entrance. Therefore, the erroneous boarding as described above hardly occurs.

  As described above, according to the present embodiment, the user is divided into the front entrance and the back entrance according to the direction, so that even if the hall lantern is not installed, the user erroneously gets on the elevator in the reverse direction. It becomes difficult. For this reason, there is no need to limit the elevators to be allocated, and it is difficult for the transport efficiency to decrease.

  In the above description, the case where the present invention is applied to an elevator system that adopts a landing destination floor registration method has been described. However, the present invention applies to an elevator system that employs a normal up-down direction calling method that does not employ a landing destination floor registration method. If applied, it is also effective in preventing cheating. In other words, in the conventional up-and-down direction calling method, a so-called cheat action may be performed in which one user registers calls in both directions at the landing and gets into the elevator regardless of the direction. If such an action is frequently performed, there is a problem that the number of times the elevator stops stops and the transportation efficiency decreases. However, according to the present invention, such a cheat action can be prevented.

(Embodiment 2)
The elevator system in Embodiment 2 is demonstrated. In the second embodiment, control for suppressing unassigned users from being left behind will be described. In the second embodiment, the hardware configuration of each device may be the same as that in the first embodiment, except that the program stored in the storage unit 12 of the group management control device 10 is different from that in the first embodiment. Therefore, in the following, the control operation by the group management control device 10 will be mainly described.

1. Operation FIG. 9A is a flowchart showing an example of a call assignment control operation in the second embodiment. The processing of this flowchart is executed at a predetermined cycle.

  The group management control device 10 determines whether or not a landing destination floor call is newly registered (S21).

  When a new landing destination floor call is not registered (NO in S21), the group management control device 10 ends the process of this flowchart.

  When a new landing destination floor call is registered (YES in S21), the group management control device 10 sets the departure floor of the new call in the variable SFL and sets the direction of the new call in the variable DIR (S22). In the following, they are simply called SFL and DIR. The same applies to other variables.

  The group management control device 10 assumes that it is possible to assign a call until the second round of each unit, and the number of laps ROUND [CAR] of each unit that can respond to a new call without causing any unloading of the user and in that case The waiting time increment dWT [CAR] is calculated (S23). ROUND [CAR] stores a value indicating whether the CAR machine responds to a new call in the first lap or the second lap. When the CAR unit responds in the first lap, 1 is set in ROUND [CAR], and when the CAR unit responds in the second lap, 2 is set in ROUND [CAR]. If the user remains unsuccessful in any response, ROUND [CAR] is set to 0.

  The group management control device 10 has ROUND [CAR] set in step S23 larger than 0, that is, can respond to a new call without causing any unloading, and the dWT [CAR] obtained in step S23 is A new call is assigned to the smallest unit (S24).

  The group management control device 10 sets the assigned car number in the variable ACAR (S25).

  The group management control device 10 determines whether or not the ACAR machine is scheduled to respond to the rear entrance in the round of the value indicated by ROUND [ACAR] (S26). ROUND [ACAR] stores a value indicating whether the ACAR machine responds to a new call in the first lap or the second lap. Specifically, it is determined whether or not the value of the array variable DO [ACAR] [ROUND [ACAR]] [SFL] [DIR] is REAR. Details of this determination will be described later.

  When the ACAR machine is scheduled to respond to the back entrance (YES in S26), the group management control device 10 assigns a new call to the back entrance of the ACAR car (S28).

  On the other hand, when the ACAR machine is not scheduled to respond to the rear entrance (NO in S26), the group management control device 10 assigns a new call to the front entrance of the ACAR machine (S27).

  The group management control device 10 displays the assigned entrance identification symbol on the call registration device 20 (S29). Specifically, the group management control device 10 transmits allocation result information including the assigned entrance identification symbol to the call registration device 20, and the call registration device 20 performs allocation based on the received allocation result information. An entrance identification symbol is displayed on the display unit 24.

  The group management control device 10 transmits the assigned information (front entrance / back entrance (straight back)) together with the new call information (departure floor / destination floor) to the elevator control device 30 of the assigned car (S30).

  FIG. 9B is a flowchart showing an example of the calculation operation of the response round ROUND [CAR] and the waiting time increment dWT [CAR] of the car No.

  The group management control device 10 sets 1 to the variable CAR (S41).

  The group management control device 10 obtains the predicted total waiting time of all waiting customers of the CAR unit at the present time, and substitutes it into WT0 [CAR] (S42).

  The group management control device 10 estimates the number of passengers between the floors when it is assumed that the CAR No. 1 responds to a new call in the first lap (S43).

  The group management control device 10 determines whether or not the number of passengers estimated between any floors exceeds a predetermined value (S44).

  When the estimated number of passengers does not exceed the predetermined value (NO in S44), the group management control device 10 waits for all waiting passengers in the CAR unit when it is assumed that the CAR unit responds to a new call in the first lap. The time sum is predicted and assigned to WT1 [CAR] (S45).

  The group management control device 10 sets 1 in ROUND [CAR] indicating that it is assumed that the CAR No. 1 responds to a new call in the first lap (S46).

  The group management control device 10 calculates the waiting time increment of the CAR No. (S47). Specifically, a value obtained by subtracting WT0 [CAR] from WT1 [CAR] is substituted into dWT [CAR].

  When the estimated number of passengers exceeds a predetermined value (YES in S44), the group management control device 10 estimates the number of passengers between the floors when it is assumed that the CAR No. 2 responds to a new call in the second lap. (S48).

  The group management control device 10 determines whether or not the number of passengers estimated between any floors exceeds a predetermined value (S49).

  When the estimated number of passengers does not exceed the predetermined value (NO in S49), the group management control device 10 waits for all waiting passengers in the CAR unit when it is assumed that the CAR unit responds to a new call in the second lap. The total time is predicted and substituted into WT1 [CAR] (S50).

  The group management control device 10 sets 2 indicating that the CAR machine responds to a new call in the second lap in ROUND [CAR] (S51), and then executes Step S47.

  When the estimated number of passengers exceeds the predetermined value (YES in S49), the group management control device 10 sets 0 in ROUND [CAR] indicating that the CAR No. cannot respond to a new call (S52). ).

  The group management control device 10 sets a value obtained by adding 1 to CAR as a new CAR (S53), and determines whether CAR is larger than MAXCARN (S54).

  When CAR is not larger than MAXCARN (NO in S54), the group management control device 10 returns to step S42.

  When CAR is larger than MAXCARN (YES in S54), the group management control device 10 executes step S24 of FIG. 9A.

  FIG. 9C is a flowchart showing an example of the setting operation of the array variable DO [X] [N] [F] [D].

  The group management control device 10 sets an array variable DO [X] [N] [F] [D] that indicates which door opening should be given priority when the X machine stops on the Fth floor D direction on the Nth lap. Initialization is performed (S121). Specifically, NIL is set to DO [X] [N] [F] [D].

  The group management control device 10 determines whether or not a new call in the F-floor D direction has been assigned to the X machine (S122).

  When a new call in the F-floor D direction is not assigned to the No. X machine (NO in S122), step S131 described later is executed.

  When a new call in the F-floor D direction is assigned to the X machine (YES in S122), the group management control device 10 determines whether the assignment of the new call is an assignment to the front entrance (S123).

  When the assignment is to the front entrance (YES in S123), the group management control device 10 sets FRONT in the ASG (S124). ASG is set to FRONT or REAR, and ASG is FRONT means that a new call is assigned to the front entrance, and ASG is REAR that a new call is assigned to the rear entrance Means.

  If it is not assigned to the front entrance (NO in S123), the group management control device 10 sets REAR in the ASG (S125).

  The group management control device 10 determines whether DO [X] [1] [F] [D] is an ASG (S126).

  When DO [X] [1] [F] [D] is ASG (YES in S126), the group management control device 10 executes Step S131 described later.

  If DO [X] [1] [F] [D] is not ASG (NO in S126), the group management control device 10 determines whether or not the new call is a VIP-only call (S127). The VIP-only call is a priority call for preferentially serving a VIP.

  When the new call is a VIP-only call (YES in S127), the group management control device 10 sets DO [X] [1] [F] [D] to DO [X] [2] [F] [D]. After the substitution, ASG is substituted into DO [X] [1] [F] [D] (S133), and Step S131 described later is executed.

  If the new call is not a VIP-only call (NO in S127), the group management control device 10 determines whether DO [X] [1] [F] [D] is NIL (S128).

  When DO [X] [1] [F] [D] is not NIL (NO in S128), the group management control device 10 sets ASG in DO [X] [2] [F] [D] (S129). ).

  When DO [X] [1] [F] [D] is NIL (YES in S128), the group management control device 10 sets ASG in DO [X] [1] [F] [D] ( S130).

  The group management control device 10 determines whether the No. X machine has arrived in the F-floor D direction (S131).

  When the X machine arrives in the F-floor D direction (YES in S131), the group management control device 10 sends DO [X] [2] [F] [D to DO [X] [1] [F] [D]. ] Is substituted, NIL is substituted for DO [X] [2] [F] [D] (S132), and the process returns to step S122.

  When the X machine has not arrived in the F floor D direction (NO in S131), the group management control device 10 returns to step S122.

2. Conventional Problems and Effects of the Present Embodiment In the landing destination floor registration system in which the destination floor is registered in advance at the landing, all users register calls at the landing. Therefore, the number of passengers can be controlled by assigning calls. However, if a large number of users exceeding the elevator's transportation capacity are concentrated, calls registered in the landing destination floor registration system cannot be assigned to any elevator (no elevator can be boarded even if assigned to any elevator) ) Situations may arise.

  However, in this embodiment, even when a large number of users are concentrated, a new call for one floor can be alternately assigned to the front entrance and the back entrance for each lap for the double-side entrance elevator. Therefore, for example, the user waiting in front of the front entrance at the time of response this time gets on board, and the user waiting at the front entrance at the time of next response gets on board, alternately at the front entrance and back entrance. It is possible to get on board. In other words, twice as many calls as when there is only one entrance can be assigned to one elevator. Therefore, it is possible to suppress the occurrence of a situation where a call cannot be assigned to any elevator (a situation where a call is left even if assigned).

(Embodiment 3)
The elevator system in Embodiment 3 is demonstrated. In the third embodiment, control for enhancing transportation capability will be described. The hardware configuration of each device may be the same as in the first embodiment. Therefore, in the following, the control operation by the group management control device 10 will be mainly described.

1. Operation FIG. 10 is a flowchart showing an example of call assignment control operation according to the third embodiment. The processing of this flowchart is executed at a predetermined cycle.

  The group management control device 10 determines whether or not a landing destination floor call is newly registered (S61).

  When a new landing destination floor call is not registered (NO in S61), the group management control device 10 ends the process of this flowchart.

  When a new landing destination floor call is registered (YES in S61), the group management control device 10 determines whether or not the current time is included in the attendance time zone (S62).

  If the current time is not the attendance time zone (NO in S62), the group management control device 10 performs a normal destination floor call assignment process for the new landing destination floor call (S63).

  The group management control device 10 assigns a new call to the front entrance of the assigned number machine (S64).

  When the current time is the working time zone (YES in S62), the group management control device 10 determines whether the departure floor of the new call is the lobby floor (S65). The lobby floor is a floor that has an entrance for entering and exiting outside and inside of the building, and is used when tenants move to other floors in the building. The number of passengers is the largest among the multiple floors. The lobby floor is, for example, the first floor. The lobby floor is an example of a specific floor.

  When the departure floor of the new call is not the lobby floor (NO in S65), the group management control device 10 executes step S63 and subsequent steps.

  When the departure floor of the new call is the lobby floor (YES in S65), the group management control device 10 determines whether there is a registered call having the same departure floor and destination floor as the new call (S66).

  When there is a registered call having the same departure floor and destination floor as the new call (YES in S66), the group management control device 10 assigns the new call to the entrance to which the registered call is assigned. It is determined whether the number of passengers between any of the floors exceeds a predetermined value (S67).

  If the number of passengers does not exceed the predetermined value between any floors (NO in S67), the group management control device 10 assigns a new call to the entrance to which the registered call is assigned (S68).

  Group management control when the number of passengers between any of the floors exceeds a predetermined value (YES in S67) or when there is no registered call having the same departure floor and destination floor as a new call (NO in S66) When the device 10 assigns a new call, the device 10 excludes an entrance where the number of assigned destination floors above the lobby floor exceeds a predetermined value from the assignment candidates (S69).

  When the group management control device 10 assigns a new call, the group management control device 10 excludes, from the assignment candidates, entrances where the number of passengers between any floors exceeds a predetermined value (S70).

  The group management control device 10 selects an entrance with the shortest waiting time for a new call from among the assignment candidate entrances, and assigns the new call (S71).

  The group management control device 10 displays the assigned entrance identification symbol on the call registration device 20 (S72). Specifically, the group management control device 10 transmits allocation result information including the assigned entrance identification symbol to the call registration device 20, and the call registration device 20 performs allocation based on the received allocation result information. An entrance identification symbol is displayed on the display unit 24.

  The group management control device 10 transmits the information on the entrance (front entrance / back entrance (straight back)) together with the new call information to the elevator control device 30 of the assigned number machine (S73).

2. Conventional Problems and Effects of the Present Embodiment FIG. 11 is a diagram showing problems and effects of the present invention. FIG. 11 shows an example in which three elevators exist and serve the seventh floor in order to facilitate the explanation of the problem and the effect of the present invention.

  Conventionally, the landing destination floor registration system is configured to allocate users (calls) concentrated on the lobby floor at the time of work to each elevator floor and assign them to each elevator. Shortening and improving transportation capacity. For example, in the example of FIG. 11, six floors other than the first floor are assigned to each elevator on the second floor. However, during work hours when the number of users increases, it is easy for the elevators to become full when they leave the first floor. When such a situation occurs, the elevators leaving the first floor will drop passengers. It was necessary to stop at least on the second floor.

  However, in the control of the flowchart of FIG. 10 of the present embodiment, for example, by setting the predetermined value in steps S69 and S70 to 1, only the users (calls) for the first floor are assigned to the front entrance and the back entrance, respectively. It will be. Therefore, the elevator only needs to service (stop) only the first floor in one lap. More specifically, in the conventional configuration, assuming that Unit 1 transported a total of 10 people per lap, 2nd floor and 5th floor, a total of 10 people, 2nd floor and 5th floor A total of 20 people can be transported. At this time, the total number of stops in two rounds is four. On the other hand, in this embodiment, a total of 20 people can be transported by transporting 10 people to the second floor in the first round and 10 people to the fifth floor in the second round. At this time, the total number of stops in two rounds is two. Therefore, according to the present embodiment, the number of stops per lap can be reduced while carrying the same number of persons as in the past in two laps. Therefore, compared with the past, the time of one round can be shortened and many users can be transported per unit time.

  As described above, according to the present embodiment, the user can be distributed not only to a plurality of elevators but also to the front entrance and the back entrance. Thereby, as described above, the number of stops per round can be reduced, and the transportation capacity can be further improved.

(Embodiment 4)
The elevator system in Embodiment 4 is demonstrated. In the fourth embodiment, control when VIP (Very Important Person) gets on the elevator will be described. The hardware configuration of each device may be basically the same as that of the first embodiment, but the call registration device 20 has means for identifying that the user is a VIP. The means for identifying is a card reader provided alongside the call registration device 20, and reads information indicating that it is a VIP from an ID card possessed by the VIP.

1. Operation FIG. 12 is a flowchart showing an example of call assignment control operation according to the fourth embodiment. The processing of this flowchart is executed at a predetermined cycle.

  The group management control device 10 determines whether or not a new landing destination floor call has been registered (S81).

  When a new landing destination floor call is not registered (NO in S81), the group management control device 10 ends the process of this flowchart.

  When a new landing destination floor call is registered (YES in S81), the group management control device 10 determines whether or not the new call is a VIP-only call (S82). This determination is made based on, for example, whether a signal indicating information indicating the VIP is received from the card reader.

  When the new call is not a VIP-only call (NO in S82), the group management control device 10 sets a unit to which a VIP-only call is not currently assigned as an allocation candidate (S83).

  The group management control device 10 performs a normal destination floor call assignment process for a new landing destination floor call (S84).

  The group management control device 10 assigns a new call to the front entrance of the assigned number machine (S85), and executes step S88 described later.

  When the new call is a VIP-only call (YES in S82), the group management control device 10 sets an entrance on the departure floor of the new call to which no current call is assigned as an allocation candidate (S86).

  The group management control device 10 selects an entrance from which the elevator can respond in the shortest time when the VIP dedicated call is assigned, from the assignment candidates, and assigns a new call (S87). In addition, when the VIP exclusive call and the general call are assigned to the front entrance and the back entrance of the same unit and the same floor, the waiting time is calculated as a response to the VIP exclusive call first. If there is a general call allocation floor in the middle of answering a VIP-only call, the waiting time is calculated as passing through this.

  The group management control device 10 displays the assigned entrance identification symbol on the call registration device 20 (S88). Specifically, the group management control device 10 transmits allocation result information including the assigned entrance identification symbol to the call registration device 20, and the call registration device 20 performs allocation based on the received allocation result information. An entrance identification symbol is displayed on the display unit 24.

  The group management control device 10 transmits the information on the entrance (front entrance / back entrance (straight back)) together with the new call information to the elevator control device 30 of the assigned number machine (S89).

2. Conventional Problems and Effects of the Present Embodiment In the case of landing destination floor registration, since call assignment cannot be changed in principle, it is difficult to preferentially service a call even if a VIP-only call is registered was there.

  FIG. 13 is a diagram illustrating an example of an elevator operation situation. Here, general users other than VIPs are referred to as general customers. In the example shown in FIG. 13, VIPs that have arrived at the landing on the first floor are assigned to the same elevator in a situation where three passengers are assigned to the elevator that is open on the sixth floor. It is assumed that the user on the 6th floor has already boarded the elevator. In the case of a conventional elevator system, if a door is opened on the 4th floor in order to take down a general customer on the 6th floor, a general customer on the 4th floor gets in and has to stop even on the 2nd floor. In addition, VIPs and general customers are waiting on the first floor, and it is impossible to eliminate the general passengers. Even if a general customer does not get on, the destination floor on the third floor has already been registered and must be stopped on the third floor. That is, in the conventional elevator system, the VIP is serviced by a route as shown by a broken line, and not only preferential service is difficult, but it is also impossible to systematically avoid riding with a general customer. Although it is possible to avoid the passengers from riding by servicing VIPs after service has been completed for all ordinary customers, there is a problem that the waiting time for VIPs is further increased.

  On the other hand, in the present embodiment, when a general passenger who gets on the 6th floor gets off at the 4th floor, by opening the door at the back entrance, as shown by the solid line in FIG. It is possible not to get on the user waiting in front, and it is not necessary to stop the elevator on the second floor of the destination floor. Therefore, the elevator can go to the first floor without stopping on the second floor, and can arrive early on the first floor where the VIP waits. In addition, by assigning the VIP on the first floor to the rear entrance, it is possible to prevent passengers waiting in front of the front entrance from getting on. Therefore, it is possible to provide direct service to the 6th floor, which is the VIP destination floor, without stopping the elevator on the 3rd floor, which is the destination floor for general customers waiting on the 1st floor. Elevator can arrive early on the floor. In addition, by eliminating the passengers waiting in front of the front entrance on the first floor, it is possible to avoid the VIP and the passengers from being boarded and to provide priority services. Furthermore, it is difficult for ordinary customers waiting in front of the front entrance on the first floor to notice even if the rear door opens. It is possible to suppress the general customer from feeling uncomfortable while eliminating the ride with the VIP.

  As described above, according to the present embodiment, VIP dedicated calls and general calls can be assigned separately to the front entrance and the back entrance, so that the VIP is given priority by responding to the VIP dedicated call first. Can be serviced.

(Embodiment 5)
The elevator system in Embodiment 5 is demonstrated. In the fifth embodiment, control for securing a user's flow line in an elevator hall will be described. The hardware configuration of each device may be the same as in the first embodiment. Therefore, in the following, the control operation by the group management control device 10 will be mainly described.

1. Operation FIG. 14 is a flowchart showing an example of call assignment control operation in the fifth embodiment. The processing of this flowchart is executed at a predetermined cycle.

  The group management control device 10 determines whether a landing destination floor call is newly registered (S101).

  When a new landing destination floor call is not registered (NO in S101), the group management control device 10 ends the process of this flowchart.

  When a new landing destination floor call is registered (YES in S101), the group management control device 10 determines whether or not the departure floor is a lobby floor (S102).

  When the departure floor is the lobby floor (YES in S102), the group management control device 10 determines whether or not the current time is included in a crowded time zone (S103).

  When the departure floor is not the lobby floor (NO in S102) or when the current time is not included in the crowded time zone (NO in S103), the group management control device 10 performs a normal call for a new landing destination floor call. A destination floor call assignment process is performed (S104).

  The group management control device 10 assigns a new call to the front entrance of the assigned number machine (S105), and executes step S108 described later.

  When the current time is included in the crowded time zone (YES in S103), the group management control device 10 determines whether the landing destination floor call is assigned to one of the two entrances facing toward the same elevator hall. If it is determined and assigned, the opposite entrance is excluded from the assignment candidates (S106).

  The group management control device 10 selects an entrance that minimizes the total waiting time of all users when a new call is assigned from among the assignment candidate entrances, and assigns the new call (S107). The total waiting time of all users can be obtained by a known method.

  The group management control device 10 displays the assigned entrance identification symbol on the call registration device 20 (S108). Specifically, the group management control device 10 transmits allocation result information including the assigned entrance identification symbol to the call registration device 20, and the call registration device 20 performs allocation based on the received allocation result information. An entrance identification symbol is displayed on the display unit 24.

  The group management control device 10 transmits the information on the assigned entrance (front entrance / back entrance (straight back)) together with the new call information to the elevator control device 30 of the assigned number (S109).

2. FIG. 15 is a diagram illustrating an example of the layout of an elevator hall to which a conventional elevator system is applied. In the landing destination floor registration method, securing the flow line of the user in the elevator hall may be a problem. For example, in the case where the entrances of a plurality of elevators are arranged facing each other as shown in FIG. 15, if there are waiting passengers in the two elevators (No. 1 and No. 6) facing each other, a new call is made. Is assigned to the elevator at the back (for example, Unit 3), and the elevator hall entrance is blocked by passengers waiting for the elevator (Unit 1 and Unit 6). It becomes difficult for a person to go deeper to the entrance of the elevator.

  However, in the elevator system of the present embodiment, when the destination floor has already been assigned to the facing entrance, the assignment to the front entrance is not performed, but the assignment to the back is performed. More specifically, in the elevator hall (front) in FIG. 2, for example, when it is already assigned to the entrance of B1, assignment to C1 is not performed and assignment is made to D1. Alternatively, if it has already been assigned to the entrance of C2, it is assigned to A2 without assigning to B2.

  As described above, according to the present embodiment, it is easy to secure a flow line in the elevator hall.

(Summary of embodiment)
(1) The elevator group management system of Embodiments 1 to 5 controls the operation of a plurality of elevators each having an entrance on the front and the back.
The elevator group management system
A call registration device 20 for accepting registration of a call at a landing by a user;
A group management control device 10 that controls operation of a plurality of elevators.
The group management control device 10
Each time a call is registered by the call registration device 20, the registered call is assigned to one of the elevators of the plurality of elevators, and
When multiple calls registered on one floor are distributed and assigned to the front entrance and back entrance of one elevator, one elevator will arrive at one floor according to a predetermined control law. Only the call assigned to the entrance of the other door is opened and only the door corresponding to one entrance is opened, and the call assigned to the other entrance is responded to the other entrance after the next lap. Open only the corresponding door.

  Thereby, in an elevator system having a plurality of elevators each provided with an entrance on the front side and the back side, it is possible to improve transportation capacity and convenience for the user.

(2) In the elevator group management system of Embodiments 1 to 5,
The group management control device 10 causes the call registration device 20 to display the assigned identification symbol (identification information) of the entrance.

  Thereby, the user can be notified of the assigned identification symbol (identification information) by display.

(3) In the elevator group management system of Embodiments 1 to 5,
The call registration device 20 accepts registration of a call specifying a destination floor.

  As a result, calls specifying the destination floor can be distributed not only to a plurality of elevators but also to the front entrance and the back entrance.

(4) In the elevator group management system of Embodiments 1 to 5,
The group management control device 10
A storage unit 12 is provided for storing the movement time between the call registration device 20 and each entrance,
When a call is registered by the call registration device 20, the registered call is assigned to an entrance that a user can reach before the departure of the elevator based on the travel time stored in the storage unit 12.

  This allows the user to reach the assigned entrance before the elevator departs.

(5) In the elevator group management system of Embodiment 1,
The group management control device 10 assigns only a call in one direction among the upward and downward calls to each entrance.

  As a result, it is possible to prevent the user from erroneously boarding the elevator that departs in the opposite direction and to smoothly board the vehicle.

(6) In the elevator group management system according to the second embodiment,
The group management control device 10
For each elevator, when a registered call is assigned in the first lap, it is determined whether the number of passengers exceeds a predetermined value between any floors. If it is set as an allocation candidate machine that responds in the lap and exceeds a predetermined value, whether the number of passengers exceeds the predetermined value between any floors when a registered call is allocated in the second lap If this determination does not exceed the predetermined value, the elevator is set as a candidate allocation machine that responds in the second lap,
Allotment candidate machines satisfying the specified condition are assigned to allotment machine,
When the allocation candidate machine that responds in the second lap is an assigned car, different entrances are assigned to the response of the first lap of the assigned car and the response of the second lap on the registration floor of the registered call.

  As a result, when the allocation candidate machine that responds in the second lap is an allocation machine, there are different entrances in the response of the first lap and the second lap of the assigned car on the registered call registration floor. Assigned. Therefore, twice as many calls as when there is only one entrance can be assigned to one elevator, and the occurrence of a situation in which no call can be assigned to any elevator can be suppressed.

(7) In the elevator group management system according to Embodiment 3,
The group management control device 10
Among all entrances, (1) the entrance where the number of destination floors already assigned when a registered call is assigned exceeds the predetermined value, and (2) any floor when a registered call is assigned The entrance that excludes the entrance where the number of passengers exceeds the predetermined value is set as the candidate entrance.
The registered call is assigned to the entry that has the shortest waiting time for the registered call among the assignment candidate entrances.

  Thereby, the registered calls can be appropriately distributed to any of the entrances depending on the number of assigned destination floors and whether the number of passengers exceeds a predetermined value between any of the floors. Therefore, the number of stops per elevator turn can be reduced. Therefore, compared with the past, the time of 1 round can be shortened and a transport capability can be improved.

(8) In the elevator group management system of Embodiment 4,
The group management control device 10 assigns a VIP-only call (specific call) whose registered call originates from a VIP (specific person) to one of the entrances to which no call is currently assigned.

  As a result, it is possible to assign a VIP dedicated call (specific call) to an arbitrary elevator instead of a specific elevator.

(9) In the elevator group management system of Embodiment 4,
When another call is assigned to the other entrance of the elevator having the entrance to which the VIP dedicated call (specific call) is assigned, the group management control device 10 is assigned to the entrance to which the VIP exclusive call (special call) is assigned. Open the corresponding door in preference to the other entrance.

  Thereby, waiting time of a specific person can be shortened.

(10) In the elevator group management system according to Embodiment 5,
When the group management control device 10 assigns the registered call to one of the two entrances facing each other across the elevator hall, the group management control device 10 responds to the call assigned to the one entrance. Do not assign a call to the other entrance.

  Thereby, it is possible to prevent the waiting line from extending from both of the two entrances facing each other across the elevator hall. Therefore, the user can move smoothly in the elevator hall.

(Other embodiments)
In the embodiment, the control units 11 and 21 of the group management control device 10 and the call registration device 20 are configured using a CPU, MPU, and the like, and use various data based on a program read from the storage unit. Thus, various functions are realized by performing arithmetic processing. That is, the control unit is realized by cooperation of hardware and software. However, the control units 11 and 21 may be configured using, for example, only hardware (electronic circuit), FPGA, ASIC, or the like.

  In the embodiment described above, the elevator group management system adopting the landing destination floor registration method has been described. However, the present invention is also applicable to an elevator group management system that employs an up / down direction call registration method in which an up / down direction call button is used to register an up / down direction call button instead of a landing destination floor registration method. For example, in the configuration in which the landing destination floor registration method is modified to the up / down direction call registration method in the first embodiment, an upper direction call is assigned to the front door and a lower direction call is assigned to the rear door. be able to.

  In the above embodiment, an example in which all of the six elevators 40-1 to 40-6 are double-sided entrance elevators has been described. However, the present invention is also applicable to a case where at least one elevator is a double-sided entrance elevator when the elevator system has a plurality of elevators. In that case, when the landing destination floor call is registered, the assignment is made to any one of all the entrances of all the elevators, and the double-sided entrance elevator may be assigned and the doors opened and closed by the above-described control.

  In the first to fifth embodiments, the control operation corresponding to the purpose of each problem has been described. However, the plurality of problems may occur at the same time or at different timings. Therefore, the control operations of the first to fifth embodiments may be executed separately for each time zone. Alternatively, detection means for detecting whether or not the problem is likely to occur may be provided, and any control operation may be executed based on the detection result. Further, a plurality of elevators may be divided into a plurality of groups and different control operations may be performed for each group.
