Description

  Embodiments described herein relate generally to an elevator control device suitable for an elevator that moves up and down by connecting a plurality of cars up and down.

  In addition to a single deck elevator composed of one car, there is a double deck elevator constructed by connecting two cars in the vertical direction. This double deck elevator can be transported in a larger amount while having the same floor space as a single deck elevator, and is mainly used as a vertical means of transportation in a building such as a skyscraper. (For example, Patent Document 1)

JP 2001-139246 A

  In an elevator hall where an elevator gets in and out of a building, there is a case where a so-called hall indicator that displays a floor on which the elevator is located is installed. In the case of a double deck elevator, since there are two cars in one elevator, two hall indicators are required for the upper car and the lower car per machine.

  Regarding the operation of the above double deck elevator, it is replaced with single operation that uses only one of the upper and lower cars, or double operation that fixes the stop floor by assigning the upper car to the even floor and the lower car to the odd floor, for example. Thus, an operation mode called semi-double operation that flexibly responds without restricting the stop floors of the upper car and the lower car can be considered. In military management control where multiple elevators are installed, when this semi-double operation is performed, the upper car of one elevator and the lower car of another elevator may be simultaneously landed and opened on one floor. possible.

  By the way, generally, an elevator hall is provided with a hall call button for registering a hall call. When the elevator user operates the hall call button, specifically, the upward call button or the downward call button, according to the direction he / she wants to go, the car responds to the hall call registration floor. When the user gets on the car and operates the destination floor call button on the in-car operation panel, the destination floor is registered, and the car moves to the destination floor.

  In recent years, an elevator group management system equipped with an operation panel (hereinafter referred to as a “destination floor registration unit”) that can directly specify a destination floor in an elevator hall has been put into practical use for an elevator system that uses this hall call button. It has become. Such an elevator group management system is called a “destination floor control system”.

  However, in the destination floor control system, the destination floor registration section must be installed in each floor elevator hall in the building, and there is a problem that the cost of equipment increases as compared with the conventional hall call button.

  Therefore, a destination floor registration unit is set up in the elevator hall on the floor where there are many users of the building, for example, the first floor which is the lobby floor, the floor where stores are gathered, or every fifth floor. A system in which a conventional system and a destination floor control system are mixed, such as installing hall call buttons in the elevator halls on other floors, is also considered.

  In a system in which such a conventional system and a destination floor control system coexist, even when the above double deck elevator is run in semi-double operation, a plurality of elevators are simultaneously landed and opened as described above. Can be considered.

  In particular, when multiple elevators open at the same time on the floor where the destination floor registration unit was installed, the user originally registered the destination floor at the destination floor registration unit and confirmed the elevator on the side assigned by the group management system It is necessary to get on, but there is a possibility of getting in a different elevator accidentally due to insufficient confirmation.

  The present embodiment has been made in view of the above circumstances, and its purpose is for operation in a destination floor control system in which a plurality of elevators that are operated by connecting a plurality of cars up and down are installed. An object of the present invention is to provide an elevator control device that can prevent a user from getting on the vehicle in error.

  The elevator control device according to the embodiment is installed in at least one of an elevator in which a plurality of cabs are connected in the vertical direction and a floor landing where the elevator cab can be stopped, and registers a destination floor. Among the plurality of operation modes for switching means and the combination of the plurality of cabs and the floor that can be stopped, when the operation mode does not limit the floors at which each of the plurality of cabs stops, the destination floor registration If it is determined that there is a landing on the floor where the means is installed and the determination means determines that there is a landing on the floor where the destination floor registration means is installed, In the floor where the destination floor registration means is installed, there is provided a display control means for distinguishing and displaying the car room stopped at the destination floor registered by the destination floor registration means of the floor and other car rooms. It is characterized by that.

  Hereinafter, an embodiment will be described in detail with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration of an entire elevator group management system in a building according to an embodiment. The “elevator” referred to here is basically a “car”, and when there are a plurality of units as in this embodiment, it is also referred to as “unit”.

  In the figure, 1 is a group management control device, and 2-1, 2-2,... Are elevator control devices that individually control the elevators of each car under the control of the group management control device 1. Each of the elevator control devices 2-1, 2-2,... Controls the cars 3-1, 3-2,. To do. The cars 3-1, 3-2,... Run up and down in the hoistways S1, S-2,.

Here, for example, the configuration of the first unit will be described assuming that each unit has basically the same configuration.
The elevator control device 2-1 includes a travel control unit 2-1A and a display control unit 2-1B. The traveling control unit 2-1A controls traveling and stopping of the car 3-1 in the vertical direction. In addition, the traveling control unit 2-1A provides the display control unit 2-1B with information indicating the state of traveling control related to the car 3-1. The control display control unit 2-1B is the first display of the display in the car 3-1 and the elevator hall of each floor based on the information given from the group management control device 1 and the travel control unit 2-1A. Control the indicator installed for the car 3-1.

  Specifically, when the upper car 3-1U and the lower car 3-1D of the first car 3-1 are referred to as the upper car 3-1D and the lower car 3-1D, respectively, Inner operation panels 4-1U and 4-1D are provided.

  The in-car operation panels 4-1U and 4-1D have a car call button, a door open button, a door close button, and a traveling state of the car 3-1 for a user who has entered the car to register the destination floor. The display control unit 2-1B controls display on the in-car display unit.

  If the floors of this building are the a floor, the b floor,... In order from the top floor, in the elevator hall of this building, the destination registration floor display section 5- 1a, 5-1b,... And lanterns 6-1a, 6-1b,. The display control unit 2-1B controls display of the destination registration floor display units 5-1a, 5-1b,... And the lanterns 6-1a, 6-1b,.

  FIG. 2 shows destination registration floor display sections 5-1a, 5-1b,..., 5-2a, 5 provided for each of the cars 3-1, 3-2,. -B,... (Hereinafter referred to as "destination registration floor display unit 5") and lanterns 6-1a, 6-1b, ..., 6-2a, 6-2b, ... (hereinafter "lantern 6"). FIG.

  Here, for example, it is assumed that an elevator in a building operates from the first floor to the 15th floor. Lower destination display floor 5A at the left end of the destination registration floor display section 5, rising display section 5B at the right end, upper car destination registration floor display section 5C at the upper half excluding the lowering display section 5A and the upward display section 5B, The lower car destination registration floor display unit 5D is arranged.

  In the figure, both the upper car destination registration floor display part 5C and the lower car destination registration floor display part 5D show the state in which all the "1" floor to "15" floor are displayed. Only the destination registration floor of the user is displayed on the upper car destination registration floor display part 5C or the lower car destination registration floor display part 5D.

  The lantern 6 is an indicator that selectively lights up or blinks in the upper part or the lower part in accordance with the traveling direction when it is determined that the corresponding car 3 will land on the floor.

  Furthermore, in the elevator hall of this building, a destination floor registration section 7 or a hall call button 8 is installed for each floor corresponding to a plurality of cars 3-1, 3-2,. In FIG. 1, for example, destination floor registration units 7a and 7b are installed on the upper a floor and b floor, and hall call buttons 8c to 8e are installed on the lower c floor to e floor.

  That is, in the a floor and the b floor where the destination floor registration sections 7a and 7b are installed, the user operates the destination floor registration sections 7a and 7b, so that the destination floor is combined with the hall call registration from the a floor and the b floor. You can register directly.

  On floors c to e where one hall call button 8c to 8e is installed, after the user gets on one of the cars 3-1, 3-2,. The destination floor is registered by operating the in-car operation panel 4 (4-1U, 4-1D) in the car room.

  The operation signals from the destination floor registration units 7 a and 7 b and the operation signals from the hall call buttons 8 c to 8 e are sent directly to the group management control device 1. Further, when the destination floor registration units 7a and 7b are configured to display the unit information as the allocation result after the input operation, the display data for that is directly given from the group management control device 1.

  Thus, in this embodiment, it is a system in which either the destination floor registration unit 7 or the hall call button 8 is installed for each floor. In FIG. 1, each floor has a destination floor registration unit 7 or a hall call button 8, but the number of destination floor registration units 7 or hall call buttons 8 is 1 for each floor. For example, the number of elevators may be the same as the number of elevators.

  The group management control device 1 and the elevator control devices 2-1, 2-2,... For each elevator are each constituted by a computer and its input / output mechanism. Inside the computer, the CPU reads out necessary programs and data from a program memory storing operation programs and various fixed data, develops and stores them in the work memory, and then sequentially executes the programs on the work memory. Thus, various control operations are executed.

Next, the operation of the above embodiment will be described.
FIG. 3 shows each display of the elevator control devices 2-1, 2-2,. The control units 2-1B, 2-2B,... Are executed in parallel with the operation control to the cars 3-1, 3-2,... By the travel control units 2-1A, 2-2A,. It is a flowchart which shows the content of the display process of destination registration floor display part 5-1a, 5-1b, ....

Hereinafter, a case where the display control unit 2-1B of the elevator control device 2-1 executes processing will be described as an example.
At the beginning of processing, the display control unit 2-1B sends an allocation result including information on the planned destination floors of the upper car 3-1U and the lower car 3-1D of the corresponding car 1 of the first car from the group management control device 1. Obtain (step S101).

  Furthermore, the display control unit 2-1B obtains information on the floor position at the current time of the upper car 3-1U and the lower car 3-1D of the passenger car 3-1 from the travel control unit 2-1A (step S102). .

  After that, the display control unit 2-1B displays information on the traveling pattern and acceleration / deceleration state of the car 3-1 at that time, that is, whether it is rising, stopping, falling, or further rising Alternatively, if the vehicle is descending, information on whether the vehicle is accelerating / decelerating or traveling at a constant speed is acquired from the traveling control unit 2-1A (step S103).

  In addition, the acquisition frequency of the allocation result including the information on the planned destination floor in the step S101 is f1, the acquisition frequency of the position information of the upper car 3-1U and the lower car 3-1D in the step S102 is f2, and the step S103. Assuming that the frequency of acquiring the travel pattern and travel state information at f3 is f3> f3> f1, not “f1 = f2 = f3”.

  For information with a lower acquisition frequency, the content acquired last time may be retained in the display control unit 2-1B and used.

  Based on the information acquired in steps S101 to S103, the display control unit 2-1B determines whether or not it is time to update the display contents on the destination registration floor display units 5-1a, 5-1b,. Judgment is made (step S104).

  Here, the timing for updating the display content is obtained from the traveling control unit 2-1A when there is a change in the assignment result including the information on the planned destination floor obtained from the group management control device 1 as compared to the previous time. When the position information of the upper car 3-1U and the lower car 3-1D at that time is different from the previous contents and when the traveling pattern of the passenger car 3-1 is switched, the passenger car 2 changes from constant speed traveling to decelerating traveling. The transition includes a case where the car 2 transitions from a stopped state to an accelerated travel.

  In step S104, when it is determined that it is not time to update the display contents on the destination registration floor display units 5-1a, 5-1b,... (NO in step S104), the display control unit 2-1B Is displayed while maintaining the contents displayed immediately before at the destination registration floor display sections 5-1a, 5-1b,... (Step S105), and then returns to the processing from step S101 again.

  If it is determined in step S104 that the display contents on the destination registration floor display units 5-1a, 5-1b,... Have been updated (YES in step S104), the display control unit 2-1B From the information of the planned destination floors assigned to the upper car 3-1U and the lower car 3-1D at the time of the car 3-1, at the destination registration floor display sections 5-1a, 5-1b,. Display contents are created (step S106).

  Based on the created display content, the destination registration floor display sections 5-1a, 5-1b,... Are displayed so as to be car-specific on each floor (step S107).

  Further, in the display control unit 2-1 B, the floor to be stopped next is a floor in which the destination floor registration unit 7 is installed instead of the hall call button 8, and the destination floor registration unit is set by the user on the floor. It is determined whether or not the operation No. 7 has been performed (whether the destination floor has been registered) (step S108).

Here, the floor where at least one of the upper car 3-1U and the lower car 3-1D of the passenger car 3-1 stops is the floor where the destination floor registration unit 7 is installed, and is used in the floor. When the operator operates the destination floor registration unit 7 and determines that the destination floor has been registered (YES in step S108), the display control unit 2-1B displays the destination registration floor display unit 5-1. The display is executed so that the car-side area including the corresponding destination floor is identified as the car-side area not including the corresponding destination floor (step S109), and the process returns to step S101.
For example, the upper car 3-1U and the lower car 3-1D are both at a lower floor position than the 10th floor and are rising, and the user is “15th floor” at the “10th floor” where the destination floor registration unit 7 is installed. When the destination call registration is performed with “” as the destination floor, the display control unit 2-1 B uses the information from the group management control device 1 to stop the next floor based on the operation on the “10th floor”. In the destination registration floor display section 5-1 of the “10th floor”, the car side area including the destination floor “15th floor” is identified as the car side area not including the destination floor. To display.

  FIG. 4 shows a destination registration floor display unit 5-1b and a lantern 6-1b corresponding to the car 3-1 on the b-th floor (14th floor) when this building has 15 floors (FIG. 4A). And the example of a display of the destination registration floor display part 5-2b and lantern 6-1b (FIG. 4 (B)) corresponding to the passenger car 3-2 is shown.

  Here, in FIG. 4A, when the lower car 3-1D of the passenger car 3-1 is within the display range of the 14th floor and immediately arrives, the destination floor “8” registered in advance by the destination floor registration unit 7b. (Floor) "is displayed on the lower car destination registration floor display unit 5D side, and the car 3-1U is landed on" 9 (floor) ".

  By configuring the destination registration floor display section 5-1b with a flat panel display such as a backlit color liquid crystal panel, the display areas of the upper car destination registration floor display section 5C and the lower car destination registration floor display section 5D are displayed. Can be temporarily set larger than the display area of the upper car destination registration floor display section 5C.

  In addition, the numerical value of “8 (floor)”, which is the planned destination floor, registered in the destination floor registration unit 7b of this floor is more prominent in a manner (color, font, size, etc.) different from the numerical values of other floors And display the entire lower car destination registration floor display portion 5D side so as to blink.

  As a result, the user who operates the planned destination floor “8 (floor)” in the 14th floor destination floor registration unit 7b can display the car under the car 3-1 from the display contents of the destination registration floor display unit 5-1b. If you ride on 3-1D, you can easily understand visually that you can go to the 8th floor.

  On the other hand, as shown in FIG. 4B, in the destination registration floor display section 5-1b corresponding to the adjacent car 3-2, the upper car 3-2U is similarly landed on the 14th floor, but the destination floor It can be understood from the display of the upper car destination registration floor display part 5C and the lower car destination registration floor display part 5D that the user does not land on the eighth floor where the destination is registered by the registration unit 7b.

  In this case, in the destination registration floor display section 5-2b, the floor in which the upper car 3-2U is scheduled to land as an area range equally divided by the upper car destination registration floor display section 5C and the lower car destination registration floor display section 5D. And the floor on which the lower car 3-2D is scheduled to land is treated equally.

  By the display on the destination registration floor display section 5-2b, together with the display on the destination registration floor display section 5-1a side, the lanterns 6-1b and 6-2b are both moved to the lower side of the car 3-1, While displaying that there is a 3-2 landing, it is possible to visually understand that the car 3-2 does not land on the 8th floor where the destination is registered in the 14th floor destination floor registration section 7b.

  In step S108, the floor where at least one of the upper car 3-1U and the lower car 3-1D of the passenger car 3-1 stops is not the floor where the destination floor registration unit 7 is installed, or Even if it is a floor where the destination floor registration unit 7 is installed, it is determined that the destination floor registration unit 7 is not operated by the user on the floor and the destination floor is not registered (step S108). NO), the display control unit 2-1B returns to the process from step S101 without performing the identification display according to the car in step S109.

  As described above in detail, according to the present embodiment, it is possible to prevent a user from getting on the vehicle in advance for operation in a destination floor control system in which a plurality of elevators that are operated by connecting a plurality of cars up and down are installed. Is possible.

  Moreover, in the said embodiment, since the judgment regarding a display was made according to the timing after determining the floor where a cage | basket | car stops next, carelessly annoying the user who waits on the floor. And can inform the user of the landing.

  In particular, in the above-described embodiment, the timing at which the cab is started to decelerate toward the floor at which the cab stops next is used as the timing for determining the floor at which the cab will stop next. Users can be notified of landing at a more appropriate timing.
