Description

  The present invention relates to an elevator control device, and more particularly, to an elevator control device that controls opening and closing of a door of a two-way door elevator having doorways in two directions on the front side and the back side.

  In buildings where two-way door elevators with entrances in two directions on the front side and the back side are installed, the directions of the entrances and exits on each floor are the front side direction only, the back side direction only, and the front side and back side directions. It is classified into three types in both directions. Among these, in the penetration floor having the entrances in both the front side and the back side, the door is opened only in either the front side or the back side due to legal restrictions.

  In such a two-way door elevator, Patent Document 1 proposes a technique for eliminating a shift in the landing position when the door opening / closing control of the door is switched from the front side to the back side.

Patent Document 2 proposes a technique for displaying a floor that can be registered for call registration when the elevator stop floor is shifted between the front side and the back side.
JP-A-11-199164 Japanese Patent Application Laid-Open No. 5-301689

  As mentioned above, due to legal restrictions, the door on the through floor cannot open both the front side and the back side at the same time, so while the door is opened in response to one landing call The other landing call may be pressed. That is, while the front door is open, the rear landing call is pushed, the front door is closed, the rear door is opened, and the rear door is opened. If the landing call is pushed on the front side and the back side in a timely manner, such as when the landing call on the front side is pushed again, the door on the through floor continues to open and close alternately indefinitely. Stops at the penetration floor.

  As described above, when the doors are alternately opened and closed on the through floor, there is a problem in that it is difficult for the elevator car to be lifted and lowered to convey the user and the luggage, which is the purpose of the elevator.

  In addition, when the landing button is pressed by a user at the landing even though the elevator car is full by a user who has already boarded, the users of the boarding and users at the landing will There is a problem that both sides are uncomfortable and the waiting time becomes longer.

  The present invention has been made in view of such a situation, and an object of the present invention is to provide an elevator control device capable of minimizing the elevator from being stopped and giving priority to the transportation of the user who gets on the vehicle. Is to provide.

  According to the first aspect of the present invention, there is an elevator control device for a two-way door elevator having two-way doors on the front side and the rear side, and there are two-way doors on the front side and the rear side. A call response unit that responds to a hall call on a penetration floor and a car call in an elevator car is provided, and the call response unit prioritizes a response to the car call under a predetermined condition.

  According to the present invention, it is possible to minimize the elevator from being stopped and to give priority to the transportation of the user who gets on the vehicle.

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

  FIG. 1 is a sectional view showing a stop floor of a two-way door elevator according to the present invention. In the case of the example of FIG. 1, the first floor is a through floor having entrances in both the front side and the back side, and the second and third floors are floors having entrances only on the front side. On the first floor, a front side landing 1a and a rear side landing 1b are provided. A front side landing 2a is provided on the second floor, and a front side landing 3a is provided on the third floor. The elevator car 4 moves up and down to the floor where the hall is located in response to the landing call registration from the elevator user, and moves up and down to the destination floor in response to the car call registration from the elevator user who has entered the elevator car 4.

  FIG. 2 is a diagram illustrating an arrangement example of the cage call button and the hall call button on the penetration floor. As shown in FIG. 2, a car call button 4a is provided at a predetermined position in the elevator car 4, and a display unit 4b is provided above the car call button 4a. For example, the display unit 4b emits modulated LED light and displays the position information of the elevator car 4, the driving direction of the elevator car 4, the registration state of the landing call, the full state, and the like.

  A front-side landing call button 1aF is provided on the wall surface of the front landing 1a, and a rear-side landing call button 1bB is provided on the wall surface of the rear-side landing 1b.

  For example, when an elevator user intends to move from the first floor front landing 1a to the destination floor using an elevator, the front passenger landing button 1aF is pressed at the first floor front landing 1a to register a landing call. . When the elevator car 4 arrives and the door opens, the elevator user gets into the elevator car 4 and presses the destination floor button on the destination floor with the car call button 4a to register the destination floor.

  Thus, the elevator user can call the elevator car 4 on a certain floor, get on the elevator car 4 that has arrived, and press the destination floor button to move to the destination floor.

  FIG. 3 is a block diagram illustrating a configuration example of the elevator control device 10.

  The call detection unit 11 detects a landing call by an elevator user. For example, it is detected that a landing floor call is registered by pressing the front side landing call button 1aF or the back side landing button 1bB, and the detection result is output to the call response unit 13. This detection result also includes information indicating which landing call on the front side or the back side is registered. The call detection unit 11 detects that the car call in the elevator car 4 is registered when the car call button 4 a is pressed, and outputs the detection result to the call response unit 13.

  The occupancy rate calculation unit 12 detects the load of the elevator car 4 using load detection means (not shown), calculates the occupancy rate of the elevator user according to the following equation (1), and outputs the calculation result to the call response unit 13. .

Occupancy rate = total weight in the elevator / rated load (1)
Moreover, the call response part 13 memorize | stores in the memory | storage part 15 the frequency | count NF by which the door on the front side of the elevator car 4 was opened, and the frequency NB by which the door on the back side was opened using the counting means which is not illustrated. The call response unit 13 responds to the landing call or the car call according to the detection result from the call detection unit 11, the calculation result from the boarding rate calculation unit 12, and the number of times of opening the door stored in the storage unit 15. Thus, the opening and closing of the door of the elevator car 4 and the raising and lowering of the elevator car 4 are controlled. The call response unit 13 functions as a call response unit that responds to a landing call or a car call.

  When the detection result from the call detection unit 11 and the calculation result from the boarding rate calculation unit 12 are in a predetermined condition, which will be described later, for example, the call response unit 13 gives priority to a response to the car call and places the landing call on the holding unit 14. To put on hold.

  Under the instruction from the call response unit 13, the holding unit 14 holds the response to the landing call and notifies the display control unit 16 that the response to the landing call is put on hold. The holding unit 14 functions as a holding unit that puts a response to a landing call on hold.

  The display control unit 16 receives a hold notification from the holding unit 14 and blinks indicator lights (not shown) such as indicators provided on the wall surfaces of the front side landing 1a and the rear side landing 1b to display the holding state. . The display control unit 16 functions as a display unit that notifies that a response to the landing call is put on hold.

  Next, the call response process executed by the elevator control device 10 will be described with reference to the flowchart of FIG.

  In step S1, the call detection unit 11 determines whether or not the elevator car 4 is stopped on the through floor (in the case of FIG. 1, the first floor). When it is determined in step S1 that the elevator car 4 is stopped at the penetration floor, the call detection unit 11 proceeds to step S2, and the front side landing call button 1aF or the rear side landing button 1bB is pressed to It is determined whether a landing call is registered.

  In step S2, when the call detection unit 11 determines that a landing floor call has been registered, the process proceeds to step S3, and the call response unit 13 causes the elevator car 4 to respond to the penetration floor landing call. Control the opening of the door. A user who registers a landing call on the through floor can get on the elevator car 4 in response to the door opening.

  In step S4, the call detection unit 11 registers a landing call at a landing (for example, the rear landing 1b) opposite to the landing (for example, the front landing 1a) for which the registration of the landing call is confirmed in the process of step S2. It is determined whether or not it has been done.

  In step S4, when the call detection unit 11 determines that a landing call is registered at the opposite landing, the process proceeds to step S5. In step S5, when the boarding rate of the elevator user calculated by the boarding rate calculation unit 12 is less than X%, the call response unit 13 responds to the landing call on the opposite side (for example, the rear side landing 1b). Thus, the door opening of the elevator car 4 is controlled. On the other hand, when the boarding rate is equal to or greater than X%, the call response unit 13 causes the holding unit 14 to hold the landing call at the opposite landing. Here, X% is 10%, for example, and can be arbitrarily changed.

  The processing so far will be described with an example. For example, when the elevator car 4 is stopped on the penetration floor (S1), when a landing call is registered by pressing the front landing call button 1aF (S2), the call response unit 13 is connected to the elevator car 4. The front door is opened (S3). Next, when a landing call is registered by pressing the reverse side landing call button 1bB on the opposite side (S4), if the number of elevator users on the elevator car 4 is small, Open the door. On the other hand, when there are many elevator users boarding the elevator car 4, it does not respond to the hall call on the opposite side but puts it on hold (S5).

  If it is determined in step S4 that the landing call is not registered at the opposite landing, or in step S5, the landing call at the opposite landing is answered or suspended according to the elevator user's boarding rate. After that, the process proceeds to step S6.

  In step S <b> 6, the call response unit 13 counts the number of times NF that the front door of the elevator car 4 is opened and the number of times NB that the rear side door is opened, and stores them in the storage unit 15.

  If it is determined in step S2 that the landing floor call is not registered, or the number of times NF that the front door is opened and the number NB that the rear door is opened in step S6 is stored. In step S7, the call detection unit 11 determines whether the car call is registered by pressing the car call button 4a.

  When it is determined in step S7 that the basket call is registered, the process proceeds to step S8, and the call detection unit 11 includes the front-side landing call button 1aF or the rear-side landing button 1bB including the landing call whose response is put on hold. When it is pressed, it is determined whether or not a landing call is registered.

  If it is determined in step S8 that the hall call including the hold has been registered, the process proceeds to step S9, where the call response unit 13 calculates the elevator user's boarding rate calculated by the boarding rate calculating unit 12 in the manner described above. Is calculated, and it is determined whether or not the boarding rate exceeds Y%. Here, Y% is 50%, for example, and can be arbitrarily changed.

  When it determines with the boarding rate of an elevator user not exceeding Y% in step S9, it progresses to step S10 and the call response part 13 is the door opening frequency NF or the door opening frequency NB memorize | stored in the memory | storage part 15. It is determined whether or not it is twice or more. Here, it is determined whether or not the door opening frequency NF or the door opening frequency NB is two or more, but the set number can be arbitrarily changed.

  Both the door opening frequency NF and the door opening frequency NB are less than 2, that is, 0 or 1, and the door opening frequency NF or the door opening frequency NB stored in the storage unit 15 is not more than 2 times. When the call response unit 13 determines in step S10, the process proceeds to step S11. The call response unit 13 controls the door opening of the elevator car 4 so as to respond to a door-side landing call with a small number of door opening times. When there is no door with a small number of doors opened, the call response unit 13 controls the door opening of the elevator car 4 so as to respond to the landing call on the side where the landing call is present. Then, it returns to step S6 and the process mentioned above is repeatedly performed.

  The processing so far will be described with an example. For example, a car call is registered when the car call button 4a is pressed (S7), a hall call including a hold is registered (S8), and the number of elevator users riding on the elevator car 4 is small (S9). When the number of times of opening the front side door and the rear side door is less than two times (S10), the call answering unit 13 opens the door with the few door opening times (S11).

  When there is no door with a small number of doors open, the call response unit 13 opens the door on the side where the landing call is located. For example, in a situation where there is no door with a small number of doors open, the elevator car 4 stops at the through floor in response to the registration of the car call by a user who has entered the elevator car 4 from a floor other than the through floor (S1). At that time, the landing call is not registered (S2), the car call is registered (S7), and then the landing call is registered (S8), the door on the front side of the elevator car 4 is opened. Both the number of times NF and the number of times NB of the back side door are opened are zero. In such a case, since there is no door with few door opening times, the door (S8) on which the landing call is registered is opened.

  If it is determined in step S9 that the boarding rate of the elevator user has exceeded Y%, or if it is determined in step S10 that the number of times of door opening NF or the number of times of door opening NB is two or more, the process proceeds to step S12. The holding unit 14 puts the response to the landing call on hold, and notifies the display control unit 16 that it has been put on hold. The display control unit 16 receives a hold notification from the hold unit 14 and blinks a display lamp (not shown) provided on the wall surface of the through floor landing to display the hold state. Thereby, the elevator user at the landing can know that the registration of the landing call is put on hold.

  If it is determined in step S8 that the landing call is not registered, or after the landing call is put on hold in step S12, the process proceeds to step S13, and the call response unit 13 responds to the car call by using the elevator car. 4 elevating and door opening are controlled.

  In step S14, the call response unit 13 controls the raising and lowering of the elevator car 4 and the opening of the door so as to respond to the landing call put on hold in the process of step S5 or step S12.

  The processing so far will be described with an example. For example, when the elevator car 4 is stopped on the penetration floor, the car call is registered (S7), and when the number of elevator users on the elevator car 4 is large (S9), the call response unit 13 is used. Puts the landing call on hold (S12) and prioritizes the response to the cage call (S13). Then, after responding to the cage call, the call response unit 13 responds to the landing call that has been put on hold (S14). In other words, when the boarding rate is equal to or higher than the set value, the user who is already in the elevator car 4 is transported with priority over the user who registered the landing call.

  If it is determined in step S1 that the elevator car 4 is not stopped on the through floor, if it is determined in step S7 that the car call is not registered, or after responding to the landing call put on hold in step S14 In step S15, the call response unit 13 controls the raising and lowering of the elevator car 4 and the opening of the door so as to perform normal operation. The normal operation is to perform a response to a landing call or a car call registered on a floor other than the through floor. The above process is repeatedly executed every time it is determined that the process has stopped at the penetration floor.

  As mentioned above, when there is a boarding call on the penetration floor, it responds to the boarding call, and when there is a boarding call on the other side, if the boarding rate is less than the set value, the boarding on the other side When the boarding rate is equal to or higher than the set value, the elevator car 4 is stopped on the through floor by putting the landing call on hold and giving priority to the car call response. It is possible to prioritize the transportation of the elevator user who is on board.

  In the description of the embodiment described above, the boarding rate is calculated using load detection. However, for example, the boarding calculated by load detection is combined with the load detection and a value calculated by a sensor or video processing. It is possible to maintain rate consistency. Thereby, it is possible to prevent a processing error due to a load detection failure.

  In addition, when the hall call is put on hold, the video in the elevator car 4 is taken and displayed on the monitor of the hall to inform the elevator users waiting at the hall of the congestion situation in the elevator car 4 Can do.

  Furthermore, as means for notifying the elevator user that the car is on hold, the registration of the hall call is put on hold by, for example, an announcement from a speaker (not shown) other than using a dedicated display device such as an indicator. I can let you know. Further, by directly blinking the front side landing call button 1aF and the rear side landing call button 1bB, it is possible to inform that the registration of the landing call is put on hold without providing a dedicated display device.

  Note that the present invention is not limited to the above-described embodiment as it is, and in the implementation stage, the constituent elements may be modified and embodied without departing from the scope of the invention, or a plurality of configurations disclosed in the above-described embodiment may be used. Various inventions can be formed by appropriately combining elements. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine the component covering different embodiment suitably.
