This display is lit for a set time and then turned off so that the next user can register. Thereby, each user can register the destination floor.

  FIG. 4 is a block diagram showing functions of the elevator control device 20 of FIG. FIG. 5 is a structural diagram showing a specific example in which the function of the elevator control device 20 of FIG. 4 is applied to an elevator of a 19-story building. The elevator control device 20 will be described with reference to FIGS. 4 and 5. As shown in FIG. 5, the building of a specific example is a 19-story building, and the same shaft 1 is provided with an upper car 2a and a lower car 2b that run independently.

  The capacity of the upper car 2a and the lower car 2b is set to 15 persons. In addition, the first floor where many users get on and off is set as a reference floor, and a lower car standby floor is provided below the first floor. In addition, since the service zones (movable ranges) of the cars 2a and 2b are not provided as in the prior art, the service zone of the lower car 2b is the standard floor to the 18th floor excluding the top floor, and the service of the upper car 2a. The zones are the standard floor to the 19th floor. That is, the service zone of the upper car 2a is from the reference floor to the top floor, and the service zone of the lower car 2b is from the reference floor to the top floor-1 floor. However, this service zone is when the number of cars 2 is N = 2. When the number N of cars 2 is N ≧ X, the service zone of each car 2 is from the standard floor to the top floor−X + 1 floor.

  As shown in FIG. 4, the elevator control device 20 includes a car reference floor arrival detection unit 21, a landing destination floor display control unit 22, a destination reservation reception unit 23, a destination floor reservation management unit 24, and a landing destination floor reservation display control unit 25. A service floor determination unit 26, a lower car operation control unit 27, and an upper car operation control unit 28.

  The car reference floor arrival detection unit 21 is a timing at which the landing destination floor reservation device 30 is operated by a user of the reference floor landing in a state where both the upper car 2a and the lower car 2b operate floors other than the reference floor. The position detection of the upper car 2a and the lower car 2b is started. Further, the car reference floor arrival detection unit 21 sends information that the upper car 2a and the lower car 2b have arrived at the reference floor to the service floor determination unit 26 and the landing destination floor display control unit 22.

  In this example, since the reference floor is set to the first floor, the car reference floor arrival detection unit 21 detects that the lower car 2b moves from the upper side to the lower side in the shaft 1 to reach the reference floor. The arrival information is sent to the service floor determination unit 26, which will be described later, when the upper car 2a moves from the upper side to the lower side in the shaft 1 and reaches the reference floor.

  Further, the car reference floor arrival detection unit 21 gives information on the stop of the lower car reference floor when the lower car 2b arrives at the reference floor and stops, and when the upper car 2a arrives at the reference floor and stops. The upper car reference floor stop information is sent to the landing destination floor display control unit 22.

  The landing destination floor display control unit 22 receives each car 2a from the service floor determination unit 26, which will be described later, in addition to the lower car reference floor stop information and the upper car reference floor stop information sent from the car reference floor arrival detection unit 21. 2b stop floor (service floor) information is received. The landing destination floor display control unit 22 sends the stop floor information of the lower car 2b to the landing destination floor display device 31 when receiving the lower car reference floor stop information and the stop floor information of each car 2a, 2b. Further, when the landing destination floor display control unit 22 receives the upper car reference floor stop information and the stop floor information of each of the cars 2a and 2b, it sends the stop floor information of the upper car 2a to the landing destination floor display device 31. The landing destination floor display device 31 is based on the stop floor information of each car 2a, 2b sent from the landing destination floor display control unit 22, and the stop floor corresponding to each car 2a, 2b stopped on the reference floor. Lights up. That is, the landing destination floor display device 31 displays the stop floors of the N cars 2 to the user based on the stop floor information.

  The destination reservation receiving unit 23 receives a destination reservation request made by a user operating the landing destination floor reservation device 30.

  The destination floor reservation management unit 24 manages the destination reservation request received by the destination reservation reception unit 23. The destination floor reservation management unit 24 sends information (destination reservation request acceptance information) that has received a destination reservation request made by the user to the landing destination floor reservation display control unit 25.

  The landing destination floor reservation display control unit 25 sends the destination reservation request acceptance information sent from the destination floor reservation management unit 24 to the landing destination floor reservation device 30. As a result, the registration completion information is displayed on the display panel 302 of FIG.

  Further, the destination floor reservation management unit 24 aggregates the number of users for each destination floor from the destination reservation request made by a plurality of users at the hall, and generates the user number information for each destination floor. The destination floor reservation management unit 24 sends the generated destination floor user number information to the service floor determination unit 26 at the timing requested by the service floor determination unit 26. The destination floor user number information generated by the destination floor reservation management unit 24 is reset when the destination floor user number information is sent to the service floor determination unit 26.

  When the service floor determination unit 26 receives the lower car arrival information from the car reference floor arrival detection unit 21, the service floor determination unit 26 sets the lower car standby floor provided below the reference floor as the stop floor of the lower car 2b (lower car standby). Floor allocation command information) is sent only to the lower car operation control unit 27. Receiving the lower car standby floor dispatch command information, the lower car operation control unit 27 moves the lower car 2b to the lower car standby floor. FIG. 5 shows a state where the lower car 2b has already moved to the lower car standby floor provided on the lower floor of the first floor.

  After the lower car 2b moves to the lower car standby floor, when the service floor determination unit 26 receives the upper car arrival information from the car reference floor arrival detection unit 21, the service floor determination unit 26 receives the destination from the destination floor reservation management unit 24. Get the number of users by floor.

  That is, the timing at which the service floor determination unit 26 requests the destination floor reservation management unit 24 for the number of users by destination floor is set to the timing at which the upper car arrival information is received from the car reference floor arrival detection unit 21. As a result, the information on the number of users by destination floor indicates that the users of the standard floor hall use the landing destination floor reservation device 30 in a state where both the upper car 2a and the lower car 2b operate floors other than the standard floor. Information for the number of users who have made destination reservation requests is included in the time from when the operation is performed until the upper car 2a arrives at the reference floor. In this example, as shown in FIG. 5, the number of users by destination floor information is “3 people for the 5th floor, 1 person for the 7th floor, 10 people for the 12th floor, 13 people for the 18th floor”.

  The service floor determination unit 26 determines the sharing of the stop floors (service floors) of the cars 2a and 2b so that the users can get on the cars 2a and 2b according to the number of users by destination floor information. Then, service floor assignment information is sent to the landing destination floor display control unit 22, the lower car operation control unit 27, and the upper car operation control unit 28.

  The following example can be considered as a specific example in which the service floor determination unit 26 determines the sharing of the stop floors of the cars 2a and 2b. First, the user to the highest floor in the number of users by destination floor information is distributed to the upper car 2a. Accordingly, the 13 users on the 18th floor shown in FIG. 5 are distributed to the upper car 2a. Next, check the number of users on the next highest floor excluding the highest floor in the destination floor user count information, and if it does not exceed the capacity of the upper car 2a, the capacity of the upper car 2a If it exceeds, then it is distributed to the lower car 2b. In the previous FIG. 5, there are 10 users to the 12th floor, which is the next higher than the 18th floor, and if the upper car 2a is allocated to the upper car 2a, the upper car 2a will exceed the capacity 15, so 10 users on the 12th floor Are distributed to the lower car 2b.

  In this way, the operation of allocating to the upper car 2a in order from the user to the upper floor, and the operation of allocating to the lower car 2b when the capacity of the upper car 2a is exceeded is the lowest in the user number information by destination floor Repeat until the floor user. As a result, in the example shown in FIG. 5, one of the users to the seventh floor is assigned to the upper car 2a, and the user to the fifth floor exceeds the capacity of the upper car 2a. 2b. Thereby, in the example of FIG. 5, the stop floor of the upper car 2a is set to the 7th and 18th floors, and the stop floor of the lower car 2b is set to the 5th and 12th floors.

  That is, when the N cars 2 depart from the reference floor sequentially, the service floor determination unit 26 determines that the user whose destination floor is closer to the top floor is closer to the top floor on the basis of the number of users by destination floor. Preferentially distributed from the car 2 located at the top. In addition, the service floor determination unit 26, when the number of users allocated to the nth car (n is an integer of 1 to N-1) exceeds the capacity of the nth car, Assign users to the basket. In this way, the service floor determination unit 26 shares the stop floors of the N cars 2.

In this way, the lower car 2b and the upper car 2a travel in the same direction in the shaft 1 at the same time by preferentially allocating to the upper car 2a in order from the user of the upper floor. Furthermore, when the capacity of the upper car 2a is exceeded, by distributing the users on the corresponding floor to the lower car 2b, it is possible to prevent the passengers who cannot get on the upper car 2a from being left behind.

  Upon receiving the service floor sharing information, the lower car operation control unit 27 and the upper car operation control unit 28 control the operation of each of the cars 2a and 2b according to the service floor sharing information after placing the user on the reference floor. The lower car operation control unit 27 and the upper car operation control unit 28 are configured to be able to communicate with each other's operation positions, and are controlled so that the cars 2a and 2b do not contact each other.

  FIG. 6 is a block diagram showing a circuit configuration of the elevator control device 20 of FIG. In FIG. 6, an elevator control computer having a CPU 40, a ROM 41, a RAM 42, and a signal conversion device 43 is used for the elevator control device 20. The function of the elevator control device 20 is realized by a corresponding elevator control computer.

  The ROM 41 stores an operation program for the elevator control device 20. The CPU 40 executes arithmetic processing based on the operation program in the ROM 42. The RAM 42 stores data necessary for control. Conversion of input / output signals to / from the corresponding elevator equipment (the landing destination floor reservation device 30, the landing destination floor display device 31, and the car call registration device 32 provided in each of the cars 2a and 2b) is a signal conversion apparatus. 43.

  FIG. 7 is a flowchart showing the operation of the elevator control device 20 of FIG. However, FIG. 7 shows only the operation of the elevator control device 20 in response to the destination reservation request registered from the reference floor. The destination reservation accepting unit 23 receives a destination reservation request (call) from the landing destination floor reservation device 30 installed on the reference floor of the elevator when both the upper car 2a and the lower car 2b are operating on other than the reference floor. The presence / absence of reception of registration is detected (destination reservation reception step, step S101). If it has been received, the destination floor reservation management unit 24 adds 1 to the number of passengers to the input destination floor (step S102). At this time, the destination floor reservation management unit 24 totals the number of users for each destination floor based on the destination reservation request received in S101 until the process proceeds to step after step S105 described later, and the number of users by destination floor Information is generated (destination floor reservation management step).

  Next, the car reference floor arrival detection unit 21 detects whether or not the lower car 2b has arrived at the reference floor (step S103). If the lower car 2b has arrived at the reference floor, the service floor determination unit 26 sends the lower car standby floor dispatch command information to the lower car operation control unit 27 (step S104).

  When the lower car 2b moves to the standby floor, the car reference floor arrival detection unit 21 detects whether or not the upper car 2a has arrived at the reference floor (reference floor arrival detection step, step S105). If the upper car 2a has arrived at the reference floor, the service floor determination unit 26 obtains information on the number of users by destination floor from the destination floor reservation management unit 24, and the stop floor (service floor) of each of the cars 2a and 2b. ) Determine sharing (service floor determination step).

  That is, when the upper car 2a and the lower car 2b each start from the reference floor, appropriate car distribution is performed according to the number of passengers for each destination floor. Specifically, as described above, the user is assigned to the upper car 2a in order from the upper floor user, and when the upper car 2a capacity is exceeded, the user of the corresponding floor is lowered. As a result, the cars 2b and 2b are sorted so that the users get on the appropriate cars according to the number of users for each destination floor.

  At the same time that the respective stop floors of the cars 2a and 2b are determined, information on the stop floor assigned to the upper car 2a on the reference floor is displayed on the landing destination floor display device 31. Further, the dispatch information to the stop floor assigned to the upper car 2a is also registered in the upper car operation control unit 28 (step S106). Thereafter, the user of the stop floor assigned to the upper car 2a gets on, and the upper car 2a starts operation.

  The landing destination floor display control unit 22 determines that the upper car 2a has departed from the reference floor when the upper car reference floor stop information is not sent from the car reference floor arrival detection unit 21. In other words, the landing destination floor display control unit 22 detects whether or not the upper car 2a has left the reference floor (step S107). When it is confirmed in step S107 that the upper car 2a has departed from the reference floor, the landing destination floor display device 31 turns off the display (step S108).

  If it is confirmed in step S107 that the upper car 2a has departed from the reference floor, the lower car 2b moves to the reference floor. When the lower car 2b arrives at the reference floor, information on the stop floor assigned to the lower car 2b is displayed on the landing destination floor display device 31. In the lower car operation control unit 27, the dispatch information to the stop floor assigned to the lower car 2b is also registered (step S109). Thereafter, the user of the stop floor assigned to the lower car 2b gets on, and the lower car 2b starts operation.

  The landing destination floor display control unit 22 determines that the lower car 2b has left the reference floor when the car reference floor stop information is not sent from the car reference floor arrival detection unit 21. That is, the landing destination floor display control unit 22 detects whether or not the lower car 2b has left the reference floor (step S110). When it is confirmed in step S110 that the lower car 2b has left the reference floor, the landing destination floor display device 31 turns off the display (step S111). Then, the process of step S101 is repeated.

  As described above, the elevator operation apparatus according to the first embodiment does not distribute passengers based on the service zone as in the prior art by the service floor determination unit 26, but according to the number of passengers for each destination floor. The allocation of the stop floor of each of the cars 2a and 2b is determined so as to be distributed to an appropriate car. As a result, even when the user's destination floor is biased, it is possible to prevent unloading. In the example of FIG. 5, for example, when the service zone of the upper car 2a is from the 11th floor to the 19th floor and the service zone of the lower car 2b is from the second floor to the 10th floor, the lower car 2b is a round trip for all users. However, since the upper car 2a exceeds the number of people that can be carried at one time, it is necessary to make two round trips. On the other hand, in the present invention, the service zone of the upper car 2a is the standard floor to the 19th floor, the service zone of the lower car 2b is the standard floor to the 18th floor, and each car shares the service zone. By appropriately allocating cars according to the number of passengers on each destination floor, it becomes possible to carry all users in one round trip.

  In addition, the service floor determination unit 26 assigns the user to the upper car 2a in order from the user to the upper floor, and when the capacity of the upper car 2a is exceeded, the service car is determined to the lower car 2b. It is possible to prevent the lower car 2b on which no passenger is riding from traveling while nobody is on it. By these, the operation efficiency of an elevator can be improved.

  Furthermore, since the service floor determination unit 26 assigns the upper car 2a with priority from the higher floor users in order, the upper car 2a and the lower car 2b travel in the same direction in the shaft 1 at the same time. Become. Further, the upper car 2a always carries the user to the floor above the lower car 2b. Thereby, the waiting time for avoiding the lower car 2b colliding with the upper car 2a can be reduced.

  Moreover, since the information of the floor where each car 2a, 2b stops is displayed on the landing destination floor display device 31, the user of the landing can grasp the destination floor of the car stopped at the landing. Thereby, it can prevent that a user gets on a different basket.

  As described above, according to the first embodiment, the elevator operating device has a plurality of cars that can travel independently within the same shaft, and the car installed at the top of the shaft has arrived at the reference floor. A car standard floor arrival detection unit, and a service floor determination unit that determines the destination division floor of each car so that the user gets on the appropriate car according to the number of users for each destination floor. Have. By providing such a configuration, even when the user's destination floor is biased, the user can be distributed to an appropriate car according to the number of users for each destination floor. As a result, the effect that operational efficiency can be improved can be acquired.

  In the above embodiment, the user makes a destination reservation request from the landing destination floor reservation device 30 provided on the landing wall, but the present invention is not limited to this. For example, when a user having an ID card or the like in which a destination reservation request is registered in advance passes through a security gate or the like, the destination reservation request may be sent from the security gate or the like to the destination reservation receiving unit 23.

  In the above-described embodiment, the hall operation unit 301 of the hall destination floor reservation apparatus 30 uses a plurality of operation buttons (tenkey buttons or floor number buttons). A button or a numeric keypad button with a card reader may be used. That is, if it is a destination floor reservation apparatus for boarding an elevator, it is not particularly specified.
