2. Operation of Elevator System (1) Overview of Conventional Elevator System In an elevator system, an elevator having an entrance provided on each of a front surface and a rear surface may be used. Conventionally, the elevator is mainly used in a parking lot, a backyard of a store, and the like, but the purpose of use is limited.

  In the present embodiment, it is an object to improve an elevator system having an elevator provided with an entrance on each of a front side and a rear side to improve transportation capacity and user convenience.

(2) Overview of Operation of Elevator System of Present Embodiment The group management control device 10 of the present embodiment generates six registered calls each time a call is registered by the call registration device 20 arranged at the landing. Assign to one of the entrances of any one of the elevators. In addition, when a plurality of calls registered on one floor are distributed and assigned to the front entrance and the rear entrance of one elevator, the group management control device 10 transmits the call to one elevator at the one floor. According to a predetermined control law, only the door assigned to one entrance is opened in response to only the call assigned to one entrance, and the next round for the call assigned to the other entrance. In response, only the door corresponding to the other entrance is opened.

  The storage unit 12 of the group management control device 10 may store a travel time table that defines the travel time from the call registration device 20 to each entrance. In this case, when a call is registered in 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 an entrance that can be reached by the user before the departure of the elevator. assign. When the departure of the elevator is not in time, the departure of the elevator may be delayed by keeping the door open.

  FIG. 6 is a diagram illustrating an example of the movement time table. In the example of the travel time table in FIG. 6, each travel 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, among operations of the elevator system, an operation according to the present invention will be specifically described.

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

  The group management control device 10 determines whether a new landing destination floor call has been registered (S11).

  If a new landing destination floor call has not been registered (NO in S11), the group management control device 10 ends the processing 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 allocation process is a process of allocating a destination floor to any one of a plurality of elevators based on a change in a waiting time or a service completion time. In the usual destination floor call assignment processing, various known assignment methods can be applied. The same applies to other flowcharts described later.

  The group management control device 10 determines whether 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, when it is downward (NO in S13), the group management control device 10 allocates a rear entrance (S15).

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

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

4. 2. Conventional Problems and Effects of the Present Embodiment (1) Conventionally, except for the top floor and the lowest floor, calls in both the upward and downward directions are assigned to one entrance. There was such a problem.
a) It is necessary for the user to board the vehicle after confirming whether or not the elevator that has arrived is the elevator in the direction to which the user is heading.
b) In the elevator hall, there are a mixture of users for calls in both upward and downward directions, that is, there are some users who do not get on when the next elevator arrives. When boarding, it is necessary to pass between users who do not get on, which may hinder smooth riding.
c) There is a case where the passenger gets into the elevator departing in the opposite direction by mistake.

  However, in this embodiment, since only one direction of the upward and downward calls is assigned to one entrance, when the elevator responds and the door is opened, a) all users It is possible to get on unconditionally, b) erroneous getting on the elevator departing in the opposite direction is suppressed, and c) it is possible to get on smoothly.

(2) FIG. 8 is a diagram showing the operation status of the elevator when there is a basement floor. Conventionally, in a landing destination floor registration system, when a hall lantern (a landing direction indicator light) is not installed, the landing destination floor in a different direction, with the same floor as a departure floor, for the purpose of preventing mistakenly taking an elevator in the opposite direction. Control may be performed so that calls are not assigned to the same elevator. In this case, since the elevators to be assigned are limited, it is impossible to select an elevator suitable for the assignment, and there is a problem that the transportation efficiency is reduced. Particularly, in a building having a basement floor, the above problem is likely to be remarkable when assigning a call to a lobby floor. For example, as shown in FIG. 8, for an elevator to which a call in the downward direction is assigned on the lobby floor, the assignment of the call in the upward direction is limited in order to prevent the user of the call in the upward direction from erroneously riding. Needed.

  However, in the present embodiment, the upward call is assigned to the front entrance, and the downward call is assigned to the rear entrance. Therefore, the erroneous boarding described above is less likely to occur.

  As described above, in the present embodiment, since the users are sorted into the front entrance and the rear entrance according to the direction, even when the hall lantern is not installed, the user may erroneously get on the elevator in the opposite direction. It becomes difficult. For this reason, it is not necessary to limit the elevators to be assigned, and the transportation efficiency does not easily decrease.

  In the above description, the case where the present invention is applied to an elevator system employing the landing destination floor registration method has been described. However, the present invention is applied to an elevator system employing a normal vertical calling method which does not employ the landing destination floor registration method. Applying is also effective in preventing cheating. That is, in the conventional vertical calling method, a so-called cheating action in which one user registers calls in both directions at the landing and gets on the elevator regardless of the direction may be performed. If such an action is performed frequently, there is a problem that the number of times the elevator stops is increased and the transportation efficiency is reduced. However, according to the present invention, such cheating can be prevented.

(Embodiment 2)
An elevator system according to Embodiment 2 will be described. In the second embodiment, a description will be given of a control for suppressing the unloading of assigned users. In the second embodiment, only the program stored in the storage unit 12 of the group management control device 10 is different from that of the first embodiment, and the hardware configuration of each device may be the same as that of the first embodiment. Therefore, hereinafter, the control operation by the group management control device 10 will be mainly described.

1. Operation FIG. 9A is a flowchart illustrating an example of a call allocation control operation according to Embodiment 2. The processing of this flowchart is executed at a predetermined cycle.

  The group management control device 10 determines whether a new landing destination floor call has been registered (S21).

  If a new landing destination floor call has not been registered (NO in S21), the group management control device 10 ends the processing of this flowchart.

  When a landing destination floor call is newly 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). Below, they are simply called SFL or DIR. The same applies to other variables.

  The group management control device 10 determines that the call can be assigned up to the second lap of each car, and determines the number of laps ROUND [CAR] of each car that can respond to a new call without generating a user's unloading. The waiting time increment dWT [CAR] is calculated (S23). ROUND [CAR] stores a value indicating whether the CAR No. 1 answers the new call in the first or second lap. When the CAR No. responds on the first lap, ROUND [CAR] is set to 1, and when the CAR No. responds on the second lap, ROUND [CAR] is set to 2. If a user is left behind in any of the rounds, ROUND [CAR] is set to 0.

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

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

  The group management control device 10 determines whether or not the ACAR No. is scheduled to respond to the rear entrance at 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 on the first or second lap. Specifically, it is determined whether or not the value of the array variable DO [ACAR] [ROUND [ACAR]] [SFL] [DIR] is REAR. The details of this determination will be described later.

  If the ACAR car is scheduled to respond to the rear entrance (YES in S26), the group management controller 10 assigns a new call to the rear entrance of the ACAR car (S28).

  On the other hand, if the ACAR car 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 car (S27).

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

  The group management control device 10 transmits the information of the assigned entrance (front entrance / rear entrance (front)) together with the information of the new call (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 operation of calculating the response cycle ROUND [CAR] of the car No. and the increment dWT [CAR] of the waiting time.

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

  The group management control device 10 obtains the total estimated waiting time of all the waiting customers of the CAR No. at the present time, and substitutes it for WT0 [CAR] (S42).

  The group management control device 10 estimates the number of passengers between floors when it is assumed that the CAR No. 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 of the floors exceeds a predetermined value (S44).

  If the estimated number of occupants does not exceed the predetermined value (NO in S44), the group management control device 10 waits for all waiting passengers of the CAR No. assuming that the CAR No. answers the new call on the first lap. The total time is predicted and substituted into WT1 [CAR] (S45).

  The group management control device 10 sets 1 to ROUND [CAR], which indicates that the CAR is assumed to respond to the new call in the first lap (S46).

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

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

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

  If the estimated number of occupants does not exceed the predetermined value (NO in S49), the group management control device 10 waits for all waiting passengers of the CAR No. assuming that the CAR No. answers the new call on the second lap. The total time is predicted and substituted into WT1 [CAR] (S50).

  The group management control apparatus 10 sets ROUND [CAR] to 2 indicating that the CAR will respond to the new call in the second lap (S51), and then executes step S47.

  If the estimated number of passengers exceeds a predetermined value (YES in S49), the group management control device 10 sets ROUND [CAR] to 0 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 the CAR as a new CAR (S53), and determines whether the CAR is greater than MAXCARN (S54).

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

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

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

  The group management control device 10 sets an array variable DO [X] [N] [F] [D] indicating which of the front doors has priority when the No. X machine stops in the F-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 a new call in the direction D on the F floor is assigned to the X-th car (S122).

  If a new call in the F-floor D direction has not been assigned to the X-th car (NO in S122), a step S131 described later is executed.

  When a new call in the direction D of the F floor is assigned to the X-th car (YES in S122), the group management control device 10 determines whether or not the assignment of the new call is to the front entrance (S123).

  If 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, where ASG is FRONT means that a new call is assigned to the front entrance, and ASG is REAR means that a new call is assigned to the rear entrance Means

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

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

  If 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 controller 10 determines whether the new call is a VIP-only call (S127). The VIP exclusive call is a priority call for giving VIP service preferentially.

  If the new call is a VIP-only call (YES in S127), the group management control device 10 sets DO [X] [2] [F] [D] to DO [X] [1] [F] [D]. After the substitution, ASG is substituted for 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).

  If DO [X] [1] [F] [D] is not NIL (NO in S128), the group management controller 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 or not the X-th car has arrived in the F-floor D direction (S131).

  If the X-th car has arrived in the direction of the floor D of the floor F (YES in S131), the group control device 10 sends DO [X] [1] [F] [D] to DO [X] [2] [F] [D]. ], And NIL is substituted for DO [X] [2] [F] [D] (S132), and the process returns to step S122.

  If the X-th car has not arrived in the direction of the F floor D (NO in S131), the group management control device 10 returns to step S122.

2. 2. Conventional Problems and Effects of the Present Embodiment In a landing destination floor registration system for registering a destination floor in advance at a landing, all users register a call at the landing, so that the number of passengers can be controlled by assigning a call. However, if a large number of users exceed the transport capacity of the elevators, the calls registered in the landing destination floor registration system cannot be assigned to any elevator. ) A situation may arise.

  However, in the present embodiment, even when a large number of users are concentrated, a new call on one floor can be alternately assigned to the front entrance and the back entrance for each round of the double-sided elevator. For this reason, for example, a user waiting in front of the front entrance is boarded at the time of this response, and a user waiting in front of the back entrance is boarded at the next response, so that the front entrance and the back entrance alternately. It is possible to get on. That is, twice as many calls as in the case of only one entrance can be allocated to one elevator. Therefore, it is possible to prevent a situation where a call cannot be assigned to any elevator (a situation where the call is left unloaded).

(Embodiment 3)
An elevator system according to Embodiment 3 will be described. In the third embodiment, control for enhancing the transport capacity will be described. The hardware configuration of each device may be the same as in the first embodiment. Therefore, hereinafter, the control operation by the group management control device 10 will be mainly described.

1. Operation FIG. 10 is a flowchart illustrating an example of a call allocation 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 a new landing destination floor call has been registered (S61).

  If a new landing destination floor call has not been registered (NO in S61), the group management control device 10 ends the processing 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 work hours (S62).

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

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

  If the current time is in the work hours (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 provided with an entrance for entering and exiting the building from outside and inside, and through which a resident moves to another floor in the building. Of the plurality of floors has the largest number of passengers. The lobby floor is, for example, the first floor. The lobby floor is an example of a specific floor.

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

  If 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 occupants does not exceed the predetermined value between any of the 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).

  If the number of passengers between any of the floors exceeds a predetermined value (YES in S67), or if there is no registered call having the same departure floor and destination floor as the new call (NO in S66), the group management control When a new call is allocated, the apparatus 10 excludes, from the allocation candidates, an entrance where the number of allocated destination floors above the lobby floor exceeds a predetermined value (S69).

  When a new call is allocated, the group management control device 10 excludes, as a candidate for allocation, an entrance where the number of passengers between any of the 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 the entrances of the allocation candidates, and assigns a new call (S71).

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

  The group management control device 10 transmits the assigned entrance information (front entrance / rear entrance (front)) together with the information of the new call to the elevator control device 30 of the assigned car (S73).

2. FIG. 11 is a diagram showing the problem and the effect of the present invention. FIG. 11 shows an example in which three elevators are provided and a 7th floor is serviced in order to facilitate the description of the problem and the effects of the present invention.

  Conventionally, the landing destination floor registration system is configured such that users (calls) concentrated on the lobby floor at the time of commuting are collectively arranged for each destination floor and allocated to each elevator in a distributed manner. And shortening transportation capacity. For example, in the example of FIG. 11, six floors other than the first floor are assigned to two elevator floors for one elevator. However, during work hours when the number of users is large, it is easy for the elevator to be full when the elevator departs from the first floor, and in such a situation, the elevator that departs from the first floor has to take down passengers. It had 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 values in steps S69 and S70 to 1, only the first floor user (call) is assigned to each of the front entrance and the rear entrance. Will be. Therefore, the elevator only needs to be serviced (stopped) on the first floor in one round. More specifically, in the conventional configuration, assuming that the first unit transports a total of 10 people to each of the second floor and the fifth floor for each lap, a total of 10 people are transported by two laps, and the second floor and the fifth floor are obtained. Can transport a total of 20 people, each with 10 people. At this time, the total number of stops in two rounds is four. In contrast, in the present embodiment, a total of 20 people can be transported by transporting 10 people to the second floor on the first lap and 10 people to the fifth floor on the second lap. At this time, the total number of stops in two rounds is two. Therefore, according to the present embodiment, it is possible to reduce the number of stops per lap while transporting the same number of people as in the past in two laps. Therefore, the time required for one round can be shortened as compared with the related art, and a large number of users can be transported per unit time.

  As described above, according to the present embodiment, users can be distributed not only to a plurality of elevators but also to front entrances and rear entrances. As a result, the number of stops per rotation can be reduced as described above, and the transport capacity can be further improved.

(Embodiment 4)
An elevator system according to Embodiment 4 will be described. In the fourth embodiment, a description will be given of control when a VIP (Very Important Person) gets on an elevator. Note that 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 identification is a card reader attached to the call registration device 20, and reads information indicating that the card is a VIP from the ID card possessed by the VIP.

1. Operation FIG. 12 is a flowchart illustrating an example of a call allocation 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 a new landing destination floor call has been registered (S81).

  If a new landing destination floor call has not been registered (NO in S81), the group management control device 10 ends the processing of this flowchart.

  When a new landing destination floor call is registered (YES in S81), the group management control device 10 determines whether the new call is a VIP-only call (S82). This determination is made based on, for example, whether a signal indicating information indicating VIP is received from the card reader.

  If the new call is not a VIP-only call (NO in S82), the group management control device 10 sets a car 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 on the new landing destination floor call (S84).

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

  If the new call is a VIP-only call (YES in S82), the group management control device 10 sets an entrance to which the current call is not assigned among the entrances on the departure floor of the new call as an assignment candidate (S86).

  When a VIP-specific call is allocated, the group management control device 10 selects an entrance to which the elevator can respond in the shortest time from among the allocation candidates and allocates a new call (S87). When a VIP-only call and a general call are assigned to the front entrance and the rear entrance of the same unit and the same floor, the waiting time is calculated assuming that the response is made first to the VIP-only call. If there is an assigned floor for a general call in the middle of responding to the VIP-only call, the waiting time is calculated as if the general call is passed.

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

  The group management control device 10 transmits the assigned entrance information (front entrance / rear entrance (front)) together with the information of the new call to the elevator control device 30 of the assigned car (S89).

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

  FIG. 13 is a diagram showing an example of an elevator operation status. Here, a general user other than the VIP is referred to as a general customer. In the example illustrated in FIG. 13, in a situation where three general customers are allocated to the elevators that are open on the sixth floor, the VIP arriving at the landing on the first floor is allocated to the same elevator. It is assumed that the user on the sixth floor has already boarded the elevator. In the case of a conventional elevator system, if the doors are opened on the fourth floor in order to drop off the general customers on the sixth floor, the general passengers on the fourth floor must get in and stop on the second floor. In addition, VIPs and general customers are waiting on the first floor, and it is not possible to exclude passengers from riding together. Even if ordinary passengers do not get on, the destination floor on the third floor has already been registered, so it must stop at the third floor. In other words, in the conventional elevator system, the VIP is serviced by a route shown by a broken line, so that not only the priority service is difficult but also the passengers cannot ride together with general passengers systematically. After all the general customers have been serviced, the VIP can be serviced to avoid passengers, but in that case, there is a problem that the waiting time of the VIP becomes longer.

  On the other hand, in the present embodiment, when a general passenger who got on the sixth floor is disembarked on the fourth floor, by opening the rear entrance door, as shown by a solid line in FIG. It is possible to prevent a user waiting in front from getting on the vehicle, 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 at the second floor, and can quickly arrive at the first floor where the VIP waits. By assigning the VIP on the first floor to the rear entrance, it is possible to prevent ordinary passengers waiting in front of the front entrance from getting on. Therefore, without stopping the elevator at the third floor, which is the destination floor for general customers waiting on the first floor, it is possible to provide direct service to the sixth floor, which is the VIP destination floor, and therefore, the VIP destination floor, which is the sixth floor, is provided. The elevator can arrive at the floor early. Also, by eliminating the general passengers waiting in front of the front entrance on the first floor, it is possible to avoid VIP and general passengers from riding together and to give priority to service. Furthermore, ordinary customers waiting in front of the front entrance on the first floor are unlikely to notice even if the back door opens. It is possible to suppress the general passengers from feeling uncomfortable while eliminating the ride with the VIP.

  As described above, according to the present embodiment, the VIP-only call and the general call can be assigned separately to the front entrance and the rear entrance, so that the VIP is given priority by responding to the VIP-only call first. Service.

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

1. Operation FIG. 14 is a flowchart illustrating an example of a call allocation control operation according to the fifth embodiment. The processing of this flowchart is executed at a predetermined cycle.

  The group management control device 10 determines whether a new landing destination floor call has been registered (S101).

  If a new landing destination floor call has not been registered (NO in S101), the group management control device 10 ends the processing of this flowchart.

  When a landing destination floor call is newly 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 congested 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 congested time zone (NO in S103), the group management control device 10 returns a normal call to the 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 car (S105), and executes step S108 described later.

  When the current time is included in the congested time zone (YES in S103), the group management control device 10 determines whether a landing destination floor call is assigned to one of the two entrances facing the same elevator hall. If it is determined that the entry has been made, the entrance on the opposite side is excluded from the assignment candidates (S106).

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

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

  The group management control device 10 transmits the assigned entrance information (the front entrance and the rear entrance (front)) together with the information of the new call to the elevator control device 30 of the assigned car (S109).

2. FIG. 15 is a diagram showing an example of a layout of an elevator hall to which a conventional elevator system is applied. In the landing destination floor registration method, securing a flow line of a user in the elevator hall may be an issue. 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 customers in two elevators (No. 1 and No. 6) facing each other, a new call is made. Is assigned to the back elevator (for example, Unit 3), the entrance allocated to the back elevator (for example, Unit 3) is closed because the entrance of the elevator hall is blocked by the waiting customers of the elevators (Unit 1 and Unit 6). This makes it difficult for the person to go to the rear of the elevator.

  However, in the elevator system according to the present embodiment, if the destination floor has already been assigned to the facing entrance, assignment to the front entrance is not performed, and assignment to the back is performed. More specifically, in the elevator hall (front) of FIG. 2, for example, if the door is already allocated to the entrance of B1, the allocation is not performed to C1 but to D1. Alternatively, if it has been assigned to the entrance of C2, it is not assigned to B2 but is assigned to A2.

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

(Summary of Embodiment)
(1) The elevator group management system according to the first to fifth embodiments controls the operation of a plurality of elevators each having an entrance at the front and at the back.
The elevator group management system
A call registration device 20 for receiving registration of a call at a landing by a user;
A group management control device 10 that controls the operation of a plurality of elevators.
The group management control device 10 includes:
Each time a call is registered in the call registration device 20, the registered call is assigned to one of the entrances of any one of the plurality of elevators,
When a plurality of calls registered on one floor are allocated to the front entrance and the rear entrance of one elevator in a distributed manner, when one elevator arrives at one floor, one elevator follows one predetermined rule. Only the door assigned to one entrance is opened in response to the call assigned to the entrance of the other entrance, and the call assigned to the other entrance is answered after the next lap by the other entrance. Only the corresponding door is opened.

  This makes it possible to improve the transportation capacity and the convenience of the user in an elevator system having a plurality of elevators each having front and rear entrances.

(2) In the elevator group management system according to the first to fifth embodiments,
The group management control device 10 causes the call registration device 20 to display the assigned identification symbol (identification information) of the entrance.

  This allows the user to be notified of the assigned identification symbol (identification information) of the entrance by display.

(3) In the elevator group management system according to the first to fifth embodiments,
The call registration device 20 accepts registration of a call specifying a destination floor.

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

(4) In the elevator group management system according to the first to fifth embodiments,
The group management control device 10 includes:
A storage unit 12 for storing a travel 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 reachable by a user 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 by the time the elevator departs.

(5) In the elevator group management system of the first embodiment,
The group management control device 10 allocates only one direction call out of the upward and downward calls to each entrance.

  As a result, the user is prevented from erroneously getting on the elevator departing in the opposite direction, and can get on smoothly.

(6) In the elevator group management system according to the second embodiment,
The group management control device 10 includes:
For each elevator, when the registered call is allocated in the first lap, it is determined whether or not the number of occupants exceeds a predetermined value between any of the floors. If the number does not exceed the predetermined value, the elevator is set to 1 If it is set as an allocation candidate car that responds on the lap and exceeds a predetermined value, if the registered call is allocated on the second lap, whether or not the number of passengers between any of the floors exceeds the predetermined value If this determination does not exceed the predetermined value, the elevator is set as an allocation candidate car that responds in the second lap,
Among all the allocation candidate units, an allocation candidate unit that satisfies predetermined conditions is set as an allocation unit,
In the case where the assigned candidate car that responds in the second lap is the assigned car, different entrances are assigned to the first lap response and the second lap response of the assigned car at the registered floor of the registered call.

  As a result, when the assigned candidate car that responds in the second lap is set as the assigned car, at the registration floor of the registered call, there is a different entrance between the first lap response and the second lap response of the assigned car. Assigned. Therefore, twice as many calls as in the case where there is only one entrance can be assigned to one elevator, and the occurrence of a situation where calls cannot be assigned to any elevator can be suppressed.

(7) In the elevator group management system according to the third embodiment,
The group management control device 10 includes:
Among all the entrances, (1) an entrance where the number of destination floors allocated when a registered call is allocated exceeds a predetermined value; and (2) any floor when a registered call is allocated. The entrance excluding the entrance where the number of occupants exceeds a predetermined value, is set as the entrance of the allocation candidate,
The registered call is allocated to the entrance having the shortest waiting time for the registered call from the entrances of the allocation candidates.

  Thereby, the registered call can be appropriately distributed to any of the entrances according to the number of assigned destination floors and whether or not the number of occupants exceeds a predetermined value between any of the floors. Therefore, the number of stops per one round of the elevator can be reduced. For this reason, the time required for one round can be shortened as compared with the related art, and the transportation capacity can be improved.

(8) In the elevator group management system according to the fourth embodiment,
The group management control device 10 allocates a VIP-specific call (specific call) in which the registered call is caused by the VIP (specific person) to one of the entrances to which the call is not currently allocated.

  This makes it possible to assign a VIP-only call (specific call) to an arbitrary elevator instead of a specific elevator.

(9) In the elevator group management system according to the fourth embodiment,
When another call is previously assigned to the other entrance of the elevator having the entrance to which the VIP-specific call (specific call) is assigned, the group management control device 10 assigns the VIP-only call (specific call) to the entrance to which the VIP-only call (specific call) is assigned. Open the corresponding door in preference to the other entrance.

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

(10) In the elevator group management system according to the fifth embodiment,
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.

  Thus, it is possible to prevent a queue of waiting customers 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 above 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, an MPU, and the like, and use various data based on a program read from the storage unit. Various functions are realized by performing arithmetic processing. That is, the control unit is realized by cooperation between hardware and software. However, the control units 11 and 21 may be configured using, for example, only hardware (electronic circuit) using an FPGA, an ASIC, or the like.

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

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

  In the first to fifth embodiments, the control operation according to the purpose of each problem has been described. However, there is a case where the above-mentioned problems occur simultaneously or at different timings. Therefore, the control operations of the first to fifth embodiments may be executed separately for each time zone. Alternatively, a detection unit for detecting whether or not the situation is likely to cause the problem may be provided, and one of the control operations 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.
