Description

  Embodiments of the present invention relate to an elevator control system and method.

  2. Description of the Related Art Conventionally, a two-way elevator in which doors are provided in two directions on the front side and the back side of a cage is known. In general, a two-way elevator has a door that preferentially responds to calls and is controlled so that the two doors do not open simultaneously. For example, when the front door is a door that responds preferentially, the front door opens, the front user gets on and off, the front door closes, and then the rear door Opens. For this reason, the user on the back side waits for a long time until the door on the back side opens.

  As a method for shortening the waiting time, there is a method of opening both doors at the same time. However, if the doors on both sides are opened at the same time, it is difficult for a user who gets off the car to determine which door he should get off from, and the ease of use of the elevator deteriorates.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
An elevator control system (hereinafter referred to as “system”) according to a first embodiment will be described with reference to FIGS. The system according to this embodiment controls a two-way elevator. The two-way elevator is an elevator in which doors are provided in two directions on one side and the other side of the cage. The one side and the other side may be opposed such as the front side and the back side, or may be adjacent such as the front side (back side) and the right side (left side). In the following, it is assumed that one side is the front side and the other side is the back side.

  FIG. 1 is a diagram illustrating a two-way elevator to be controlled by the system according to the present embodiment. The two-way elevator can register a front side car call, a back side car call, a front side hall call, and a back side hall call. In the example of FIG. 1, the two-way elevator includes a hoistway from the first floor (1F) to the third floor (3F), and the cage 1 moves up and down in the hoistway.

  The basket 1 includes doors 11 and 12 and operation panels 13 and 14. The door 11 is a door provided on the front side of the basket 1. The door 11 opens in response to calls on the front side (basket call and hall call). The door 12 is a door provided on the back side of the basket 1. The door 12 opens in response to calls on the back side (basket call and hall call). Hereinafter, the timing at which the doors 11 and 12 start to open is referred to as door opening timing. The system according to the present embodiment determines the opening timing of the doors 11 and 12 according to the call registration state. The method for determining the door opening timing will be described later in detail.

  The operation panel 13 is an operation panel for registering a car call on the front side. The operation panel 13 includes a basket call button corresponding to each floor (first to third floors). When the car call button on the operation panel 13 is pressed, the car call on the front side is registered with the floor corresponding to the car call button as the destination floor. When the car 1 responds to this car call, the door 11 opens on the registered destination floor.

  The operation panel 14 is an operation panel for registering a cage call on the back side. The operation panel 14 includes a basket call button corresponding to each floor (first to third floors). When the car call button on the operation panel 14 is pressed, the car call on the back side is registered with the floor corresponding to the car call button as the destination floor. When the car 1 responds to this car call, the door 12 opens on the registered destination floor.

  As described above, in the present embodiment, the two-way elevator can register a front side car call and a back side car call. In the example of FIG. 1, the car 1 includes two operation panels for registering the front and rear car calls. However, if the front and back basket calls are registered, only one operation panel may be used. As an operation panel capable of registering the front and rear basket calls, for example, there is a console having a basket call button corresponding to each floor and a switching button for switching between the front side and the back side.

  As shown in FIG. 1, elevator halls 21 and 22 are provided on each floor where the car 1 moves up and down.

  The elevator hall 21 is an elevator hall provided on the front side of the car 1. The elevator hall 21 is provided with a hall call button 23. The hall call button 23 is a call button for registering a hall call on the front side. The hall call button 23 is provided for each raising / lowering direction of the cage 1. In the example of FIG. 1, the hall call button 23 on the first floor is located on the first floor elevator hall 21, the hall call button 23 on the upper and lower directions is located on the second floor elevator hall 21, and Directional hall call buttons 23 are provided. When the hall call button 23 is pressed, the hall call on the front side in the ascending / descending direction corresponding to the hall call button 23 is registered.

  The elevator hall 22 is an elevator hall provided on the back side of the basket 1. A hall call button 24 is provided in the elevator hall 22. The hall call button 24 is a call button for registering a hall call on the back side. The hall call button 24 is provided for each raising / lowering direction of the basket 1. In the example of FIG. 1, the hall call button 24 on the first floor is located on the first floor elevator hall 22, the hall call button 24 on the upper and lower directions is located on the second floor elevator hall 22, and the hall call button 22 on the third floor is below Directional hall call buttons 24 are provided. When the hall call button 24 is pressed, the hall call on the back side in the ascending / descending direction corresponding to the hall call button 24 is registered.

  As described above, in the present embodiment, the two-way elevator can register the hall call on the front side and the hall call on the back side. In the example of FIG. 1, the elevator halls 21 and 22 are provided on all floors (first to third floors) on the hoistway, but may be provided only on some floors on the hoistway. It is. Further, there may be a floor provided with only one of the elevator halls 21 and 22.

  FIG. 2 is a diagram illustrating an example of a system according to the present embodiment. As shown in FIG. 2, the system according to the present embodiment includes a control panel 31, a timing determination device 32, a front side door control device 33, and a back side door control device 34.

  The control panel 31 generally has functions necessary for elevator control. Specifically, the control panel 31 performs call registration in response to an input from the call button, assignment of a car to the registered call, and control of raising and lowering the car in response to the call. In addition, the control panel 31 collects and manages the state of the cage 1 (floor, lifting direction, door open / closed state, weight, etc.).

  The timing determination device 32 acquires call information from the control panel 31. Call information is information related to the registration state of a call. The call information includes information such as the car call and hall call being registered, and the assignment of the car to each call.

  The timing determination device 32 determines the door opening timing of the doors 11 and 12 based on the call information acquired from the control panel 31. The method for determining the door opening timing by the timing determination device 32 will be described later in detail. When the timing determination device 32 determines the door opening timing, it outputs a door opening command at the determined door opening timing.

  The front door control device 33 controls the opening and closing of the door 11 on the front side of the car 1. When the front door control device 33 receives a door opening command for the door 11 from the timing determination device 32, the front door control device 33 opens the door 11. Thereby, the door 11 starts to open at the door opening timing determined by the timing determination device 32.

  The back side door control device 34 controls opening and closing of the door 12 on the back side of the car 1. When receiving the door opening command for the door 12 from the timing determination device 32, the back side door control device 34 opens the door 12. Thereby, the door 12 starts to open at the door opening timing determined by the timing determination device 32.

  Here, FIG. 3 is a flowchart showing a method of determining the door opening timing by the timing determination device 32. Below, the timing determination apparatus 32 shall determine the door opening timing of the doors 11 and 12 when the cage | basket | car 1 responds to the call of the floor X. FIG. The floor X referred to here includes a car call with the floor X as the destination floor and a hall call registered from the floor X. Further, it is assumed that both the front side call and the back side call are registered as the floor X call.

  First, the timing determination device 32 refers to the call information acquired from the control panel 31 and determines the registration state of the call on the floor X to which the car 1 responds. In the present embodiment, the timing determination device 32 determines the registered state of the cage call for the floor X.

  Specifically, as shown in FIG. 3, the timing determination device 32 determines whether only the front side car call is registered (step S <b> 1). The fact that only the front side car call is registered means that the front side car call is registered and the back side car call is not registered.

  When only the car call on the front side is registered (YES in step S1), the timing determination device 32 gives priority to the front side (step S2). That is, the door opening timing is determined so that the door opening timing of the front door 11 is earlier than the door opening timing of the rear door 12. In this description, since it is premised that calls on both sides are registered, the case of YES in step S1 corresponds to a case where a car call on the front side and a hall call on the back side are registered. To do.

  On the other hand, in the case of NO in step S1, the timing determination device 32 determines whether only the rear side car call is registered (step S3). Only the rear side car call is registered means that the back side car call is registered and the front side car call is not registered.

  When only the rear side car call is registered (YES in step S3), the timing determination device 32 gives priority to the rear side (step S4). That is, the door opening timing is determined so that the door opening timing of the rear door 12 is earlier than the door opening timing of the front door 11. In this explanation, since it is premised that calls on both sides are registered, the case of YES in step S3 corresponds to a case where a rear-side basket call and a front-side hall call are registered. To do.

  On the other hand, in the case of NO in step S3, the timing determination device 32 determines the door opening timing so that the door opening timing of the front door 11 and the door opening timing of the rear door 12 are the same (step). S5). In this description, since it is assumed that calls on both sides are registered, the case of NO in step S3 is the case where the car calls on the front side and the back side are respectively registered, or the front side and the back side This corresponds to the case where none of the side car calls are registered and the front and back hall calls are registered respectively.

  FIG. 4 is a diagram illustrating an example of a call registration state. In the example of FIG. 4, a basket call on the front side of the second floor and an upward hall call on the back side of the second floor are registered (YES in step S1). When the basket 1 responds to a call as shown in FIG. 4, the timing determination device 32 gives priority to the front side (step S2). Accordingly, when the car 1 stops on the second floor, the front door 11 starts to open first, and then the rear door 12 starts to open.

  As described above, the system according to the present embodiment gives priority to the front side when the front-side basket call and the back-side hall call are registered. Further, the system gives priority to the rear side when the rear side basket call and the front side hall call are registered. That is, if the system has registered a car call on one side and a hall call on the other side, the system will indicate the side on which the car call is registered to the side on which the car call is not registered (the hall call is registered). Priority).

  When the door opening timing is determined in this way, when the car 1 stops at the floor X, the door on the side where the car call is registered starts to open. At this time, since the door opening on the side where the car call is not registered has not yet started, the user in the car 1 naturally gets off the door on the priority side. As described above, according to the system according to the present embodiment, the user can easily determine the exit door.

  Further, according to the system according to the present embodiment, the user gets off from the door on the side where the car call is registered, and from the door on the side where the car call is not registered (the side on which the hall call is registered). The user gets on. Since the flow of people getting off and the flow of people getting on do not overlap, the user can get on and off the car 1 smoothly.

  Furthermore, according to the system according to the present embodiment, getting off from the car 1 is started before getting on the car 1. When the user gets on the car 1, a space for the user who gets off the car 1 is created in advance, so that the user can get on the car 1 smoothly.

  In the present embodiment, the timing determination device 32 may be configured by a computer connected to the control panel 31 or may be configured by software operating on the control panel 31. In the flowchart of FIG. 3, the order of steps S1 and S3 may be reversed.

(Second Embodiment)
A system according to the second embodiment will be described with reference to FIGS. 5 and 6. In the first embodiment, when the cage calls on both sides are registered (NO in step S3), the doors 11 and 12 on both sides are opened simultaneously. On the other hand, in this embodiment, the door on one side is opened before the door on the other side.

  FIG. 5 is a flowchart showing a door opening timing determination method by the door opening timing determination device 32 in the present embodiment. Steps S1 to S5 in FIG. 5 are the same as in the first embodiment. Below, step S6-S8 is demonstrated.

  First, the timing determination device 32 refers to the call information acquired from the control panel 31 and determines the registration state of the call on the floor X to which the car 1 responds. In the present embodiment, as in the first embodiment, the timing determination device 32 determines the registration state of the cage call of the floor X.

  Specifically, as shown in FIG. 5, the timing determination device 32 determines whether or not both-side basket calls are registered (step S <b> 6). The registration of the car calls on both sides means that the car call on the front side is registered and the car call on the back side is registered.

  When both the car calls are not registered (NO in step S6), the timing determination device 32 determines whether only the front car call is registered (step S1). The subsequent processing is the same as in the first embodiment.

  On the other hand, when the cage calls on both sides are registered (YES in step S6), the timing determination device 32 determines the priority response side (step S7). The priority response side is a priority side of the front side and the back side.

  The priority response side may be set in advance according to the time zone, or may be determined according to the registered state of the hall call. When setting the priority response side according to the time zone, in the time zone where it is known that there are many users getting off from the front side, the priority response side is set to the front side and the user getting off from the back side In a time zone that is known to be large, the response priority side may be set to the back side. A method for determining the priority response side according to the hall call registration state will be described in detail in the third embodiment.

  When the determined priority response side is the front side (YES in step S8), the timing determination device 32 gives priority to the front side (step S2). On the other hand, when the determined priority response side is the back side (NO in step S8), the timing determination device 32 gives priority to the back side (step S4). That is, the timing determination device 32 determines the door opening timing so that the door opening timing on the priority response side is earlier than the door opening timing on the side that is not the priority response side.

  FIG. 6 is a diagram illustrating an example of a call registration state. In the example of FIG. 6, the car call on the front side of the second floor and the car call on the back side of the second floor are registered (YES in step S6). When the car 1 responds to the call as shown in FIG. 6, the timing determination device 32 determines the priority response side based on the hall call registration state and time zone (step S <b> 7), and prioritizes the determined priority response side To do.

  As described above, the system according to the present embodiment uses the other method when the car call on both sides is registered and the appropriate door opening timing cannot be determined only from the registered state of the car call. The door opening timing can be determined. Therefore, the system according to the present embodiment can determine an appropriate door opening timing according to the time zone.

  In the flowchart of FIG. 5, the order of steps S1, S3, and S6 is arbitrary. Further, in the present embodiment, the case of NO in step S3 is a case where the cage calls on both sides are not registered and the hall calls on both sides are registered.

(Third embodiment)
A system according to the third embodiment will be described with reference to FIGS. The system according to the present embodiment determines the priority response side based on the hall call registration state. FIG. 7 is a flowchart showing a priority response side determination method by the timing determination device 32 in the present embodiment. Steps S71 to S75 in FIG. 7 correspond to step S7 in the second embodiment.

  In the present embodiment, the timing determination device 32 determines the registration state of the hall call when the cage calls on both sides are registered (YES in step S6).

  Specifically, as shown in FIG. 7, the timing determination device 32 determines whether only the hall call on the front side is registered (step S71). Only the hall call on the front side is registered means that the hall call on the front side is registered and the hall call on the back side is not registered.

  When only the front hall call is registered (YES in step S71), the timing determination device 32 determines the priority response side as the back side (step S72). Thereafter, the process proceeds to step S8.

  On the other hand, in the case of NO in step S71, the timing determination device 32 determines whether only the hall call on the back side is registered (step S73). Only the hall call on the back side is registered means that the hall call on the back side is registered and the hall call on the front side is not registered.

  When only the back side hall call is registered (YES in step S73), the timing determination device 32 determines the priority response side to be the front side (step S74). Thereafter, the process proceeds to step S8.

  On the other hand, in the case of NO in step S73, the timing determination device 32 determines the priority response side by any method other than the registered state of the cage call or hall call (step S75). In step S75, for example, a priority response side set in advance for each time period may be determined as the priority response side. Further, the priority response side may be determined on both sides, and the door opening timings on both sides may be made simultaneously. Thereafter, the process proceeds to step S8.

  FIG. 8 is a diagram illustrating an example of a call registration state. In the example of FIG. 8, a car call on the front side of the second floor, a car call on the back side of the second floor, and an upward hall call on the front side of the second floor are registered (YES in step S71). . When the basket 1 responds to the call as shown in FIG. 8, the timing determination device 32 determines the priority response side as the back side (step 72). Therefore, the timing determination device 32 gives priority to the rear side, and determines the door opening timing so that the door opening timing of the rear door 12 is earlier than the door opening timing of the front door 11.

  As described above, the system according to the present embodiment determines the priority response side based on the registration state of the hall call when the front side call and the rear side call are registered respectively. Specifically, when only the hall call on the front side is registered, the back side is determined as the priority response side. When only the hall call on the back side is registered, the front side is determined as the priority response side. That is, the system according to the present embodiment determines the side on which no hall call is registered as the priority response side.

  When the priority response side is determined in this way, the door opening timing is determined so that the door opening timing on the side where the hall call is not registered is earlier than the door opening timing on the side where the hall call is registered. As a result, the user gets off the door on the side where only the cage call is registered (the side where the hall call is not registered), and the user gets on the door on the side where the hall call is registered. Since the flow of people getting off and the flow of people getting on do not overlap, the user can get on and off the car 1 smoothly.

(Fourth embodiment)
A system according to the fourth embodiment will be described with reference to FIG. The system according to the present embodiment notifies the user in the car 1 which door is opened first. FIG. 9 is a diagram illustrating an example of a system according to the present embodiment. As shown in FIG. 9, the system according to the present embodiment further includes a timing notification device 35. Other configurations are the same as those of the first embodiment.

  The timing notification device 35 notifies the user in the car 1 which of the front door 11 and the rear door 12 opens first. In the present embodiment, when the timing determination device 32 determines the door opening timing of the doors 11 and 12, the timing determination device 32 notifies the timing notification device 35 of the determined door opening timing. The timing notification device 35 determines a door to be opened first based on the door opening timing of the doors 11 and 12 received from the timing determination device 32, and generates a message for notifying the door to be opened first. , The user in the basket 1 is notified.

  The timing notification device 35 may be a speaker that notifies by outputting sound, or may be a display device that notifies by displaying a message. In any case, the timing notification device 35 is provided in the car 1 so as to notify the user in the car 1.

  As described above, the system according to the present embodiment can notify the user in the car 1 in advance which door is opened first. Therefore, the user can more easily determine the door on the exit side.

  In addition, when the timing determination apparatus 32 determines the door opening timing of the doors 11 and 12, based on the determined door opening timing, it determines the door which opens first and notifies the door which opens first. A message may be generated and the generated message may be notified to the timing notification device 35. In this case, the timing notification device 35 may notify the user in the car 1 of the message received from the timing determination device 32.

(Fifth embodiment)
A system according to the fifth embodiment will be described with reference to FIG. The system according to the present embodiment can switch the door opening timing determination method. FIG. 10 is a diagram illustrating a system according to the present embodiment. As shown in FIG. 10, the system according to this embodiment further includes a door opening condition switching device 36. Other configurations are the same as those of the first embodiment.

  The door opening condition switching device 36 outputs a switching signal for switching the method for determining the door opening timing by the timing determining device 32. In the present embodiment, the timing determination device 32 is preset with a plurality of methods for determining the door opening timing. When the timing determination device 32 receives the switching signal from the door opening condition switching device 36, the timing determination device 32 switches the method for determining the door opening timing according to the switching signal. Here, the door opening timing determination method includes the door opening registration state described in each of the above-described embodiments using the registration state of the cage call, the registration state of the hall call, and the priority response side set for each time zone. A timing determination method is included.

  The door opening condition switching device 36 may be configured by an external contact or the like installed in the elevator halls 21 and 22 of each floor, or software that operates on the control panel 31 that outputs a switching signal according to a time condition or the like. It may be constituted by.
