Description

  The present invention relates to an elevator having a function of improving the operation efficiency of a car.

  Conventionally, elevator passengers press a hall call button to call a car in a hall. Thereafter, the hall call button continues to be lit until the car arrives at the floor where the hall call button is pressed, and turns off when the car arrives at the called floor.

As a technique for improving the operation efficiency of an elevator, for example, as disclosed in Patent Document 1, when an increase in elevator demand on a specific floor is detected, the hall call button on the floor is switched to constantly lit, The response time of the car is shortened.
JP-A-6-40671

  Factors that determine the quality of elevator operation efficiency include not only the response time of the car described above, but also the stop time at each floor of the car that is moving up and down.

  For example, if all the users who were in the hall could not get into the car due to congestion of the car that arrived at a certain floor, the user who could not get in would call a new hall call after departure Attempting to do so may result in pressing a hall call button that is off.

  In conventional elevators, if the car has landed on the floor and there are hall calls or car calls remaining on the other floors before the response, When the door is completely closed, the car departs toward the other destination floor, but if the hall call button on the floor that has been landing at the timing before the departure of the car during or after the door is closed is pressed The car door I was about to leave opens again. In other words, a new hall call cannot be registered until the user gets into the arriving car and the door is completely closed and departs.

  However, as mentioned above, if the car is already crowded and full, passengers remaining in the hall cannot newly enter, so the door has been reopened as described above. If the time from the arrival of the car to the departure to other floors becomes longer, it will not only be uncomfortable for passengers in the car, but it will also take time to make a new hall call It is uncomfortable for the passengers who remain in the hall.

  Therefore, an object of the present invention is to improve the convenience of passengers in the car and in the hall by improving the efficiency of the new hall call when the car that has landed is congested. It is to provide an elevator that becomes possible.

  That is, the elevator according to the present invention is the case where it is determined that the crowded state of the car is not at a predetermined level after the car is landed, and the car is landed after the door is opened until the car departs. When the hall call button on the floor is operated, the door-opening operation is controlled, and when it is determined that the crowded state of the car is at the level described above after the landing of the car, the car is opened after the door is opened. If the floor hall call button on the floor where the floor is landed is operated before departure, the hall call registration control for the floor to respond after the departure of the car is performed without opening the door. And

  ADVANTAGE OF THE INVENTION According to this invention, the convenience for the passenger in a car and a hall | hole can be improved by improving the efficiency concerning the new hall call in the case where the boarded car is crowded.

Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
First, a first embodiment of the present invention will be described.
FIG. 1 is a schematic diagram of various elevator hall devices according to a first embodiment of the present invention. FIG. 2 is a schematic view of an elevator car according to the first embodiment of the present invention.
As shown in FIG. 1, a hall call button 3 that is operated to make a hall call in the normal state of the car 4 shown in FIG. .

  The elevator control device 1 performs hall call registration on the floor where the operated hall call button 3 is provided, makes the car 4 respond to this call, and when the car 4 reaches the car, the car control device 6 A control signal for opening the car door or the hold door 2 is output.

  Further, the elevator control device 1 is for closing the car door or the hold door 2 when a predetermined time elapses after the door is opened or when the door closing button in the car 4 is operated. A control signal is output to the car control device 6. In this case, when a registered call remains, the elevator control device 1 causes the car 4 to depart to respond to this call.

  In the present embodiment, a car load detection device 5 that detects the load of the car 4 is provided on the floor surface of the car 4. The car load detection device 5 outputs a load detection signal in the car 4 to the elevator control device 1.

  The hall call button 3 on each floor lights up when operated or when a car call on the own floor is registered. The lit hall call button 3 is turned off when the car 4 arrives at the floor where the hall call button 3 is installed and opens.

  In the elevator according to the present embodiment, the load in the car 4 is confirmed after the light is turned off, and the load arrives when the load exceeds a predetermined reference value and the passengers are full and the passengers cannot enter further. The function when the hall call button 3 is operated is changed to a new hall call registration control after departure of the car 4 instead of the conventional door opening operation.

  Further, in order to notify the passengers in the hall that the function by the operation of the hall call button 3 has been changed, the hall call on the floor where the car 4 is located when the load on the car 4 exceeds the reference value described above. Button 3 is blinked.

FIG. 3 is a block diagram showing the configuration of the elevator control apparatus for an elevator according to the first embodiment of the present invention.
As shown in FIG. 3, the elevator control device 1 includes an input unit 11, a load determination unit 12, a function control unit 13, and an output unit 14.

  The input unit 11 inputs signals from the hall call button 3 and the car load detection device 5. The load determination unit 12 determines whether or not the load in the car 4 exceeds a predetermined reference value based on the detection result by the car load detection device 5.

  The function control unit 13 controls the opening when the hall call button 3 on the floor on which the car 4 is landing is operated before the car 4 starts, and after the car 4 starts. Switch between new hall call registration functions.

  The output unit 14 outputs a control signal for opening the car door or the hold door 2 to the car control device 6.

  Next, the processing operation of the elevator having such a configuration will be described. FIG. 4 is a flowchart illustrating an example of the processing operation of the elevator according to the first embodiment of the present invention.

  First, when there is a registered car call or hall call, the elevator control device 1 causes the car 4 to respond to these calls (step S1). In this case, the hall call button 3 of the hall to be responded is lit.

  When the car 4 reaches the destination floor (step S2), the elevator control device 1 cancels the call of the floor, outputs a door opening control signal to the car control device 6, and also the floor on which the landing has been made. The hall call button 3 of the floor hall is turned off (step S3). Here, it is assumed that registered calls relating to other floors remain.

  And the input part 11 of the elevator control apparatus 1 inputs the detection signal from the car load detection apparatus 5 of the car 4 (step S4). The load discriminating unit 12 discriminates whether or not the load in the car 4 exceeds the predetermined reference value described above by comparing the load indicated by the detection result with a predetermined reference value. (Step S5). The reference value is a value that is regarded as a congested state in which the car 4 is congested and a new person cannot enter.

  When the load determination unit 12 of the elevator control device 1 determines “NO” in the process of step S5, the function control unit 13 regards that the passenger car 4 is not in a congested state in which a person cannot newly enter, If the hall call button 3 of the floor on which the floor is landing is operated until the time when the door is opened or when the car 4 is started by the door closing button operation (YES in step S6) ) In the same manner as the function of a conventional elevator, a control signal for door opening control is output to the car control device 4 via the output unit 14. As a result, the car door and the hold door 2 are opened (step S7).

  Further, when the function control unit 13 of the elevator control device 1 determines “YES” in the process of step S5, the function control unit 13 regards that the passenger car 4 is in a congested state where a new person cannot enter. The function when the hall call button 3 on the landing floor is operated before the departure of the car 4 is not the door opening control but the registration of a new hall call after the departure of the car 4 In addition to switching (step S8), the hall call button 3 that has been turned off on the floor on which the floor is landing is blinked. Thereby, the passengers in the hall can recognize that the function of the hall call button 3 has changed (step S9).

  If the blinking hall call button 3 is operated (YES in step S10), the elevator control device 1 performs a new hall call registration after departure of the car 4 (step S11).

  In this case, the elevator control device 1 does not perform the door opening control unless the door opening button in the car 4 is operated, and after the door 4 is closed, after the car 4 is departed to respond to a call on another floor. Then, the car 4 is raised and lowered to respond to the hall call registered in step S11. Moreover, the function control part 13 returns the function in case the hall call button 3 of the floor where it was landing was operated before the car 4 departure to door opening control.

  On the other hand, when the hall call button 3 that is blinking is not operated (NO in step S10), when a predetermined time elapses after the door is opened or the door closing button in the car 4 is operated. The elevator control device 1 outputs a signal for door closing control to the car control device 6 via the output unit 14 and causes the car 4 to depart to respond to other floor calls.

  When the car 4 departs in this way (YES in step S12), the function control unit 13 changes the function when the hall call button 3 on the floor where the floor has been operated to the normal function. Return (step S13).

  In this case, when the hall call button 3 is operated before the landing of the car 4 to the floor on which the floor has been floored, the elevator control device 1 performs the hall call registration of the floor, as described above. When the car 4 has landed again on the floor that has been on the floor, the load determination unit 12 of the elevator control device 1 determines whether or not the load in the car 4 exceeds the predetermined reference value described above. Will be determined again.

  As described above, in the elevator according to the first embodiment of the present invention, the floor of the landing floor 4 is closed before the door is closed in a state where the landing car 4 is congested and a new person cannot enter. When the call button 3 is operated, a new hall call after departure of the car 4 is registered instead of performing door opening control. As a result, a new hall call after the departure of the car 4 can be made quickly for a user who has not been able to get into the car 4 that has arrived. Since the user does not open the door again, the user can move to the destination floor smoothly.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In addition, description of the same part as 1st Embodiment among the structures of the elevator which concerns on this embodiment is abbreviate | omitted.
FIG. 5 is a schematic view of an elevator car according to the second embodiment of the present invention.

  In this embodiment, as compared with the first embodiment, instead of using the car load detection device 5 for determining the congestion state of the car 4, the car camera 21 which is a photographing means in the car 4 is used. Is installed, and it is determined whether or not the congestion state of the car 4 is at a predetermined level on the basis of the image taken by the in-car camera 21.

FIG. 6 is a block diagram showing a configuration of an elevator control device for an elevator according to the second embodiment of the present invention.
In this embodiment, as shown in FIG. 6, the elevator control device 1 includes an image determination unit 22 instead of the load determination unit 12. The image discriminating unit 22 discriminates whether or not the congestion state in the car 4 is at a predetermined level based on the photographing result by the car camera 21. The input unit 11 inputs a signal from the hall call button 3 and a photographed image from the in-car camera 21.

Next, the processing operation of the elevator having such a configuration will be described. FIG. 7 is a flowchart showing an example of an elevator processing operation according to the second embodiment of the present invention.
First, after the processing of steps S1 to S3 in the first embodiment (steps S21, S22, S23), the input unit 11 of the elevator control device 1 inputs a photographed image from the in-car camera 21 of the car 4 (steps). S24). The image discriminating unit 22 analyzes this captured image and detects the proportion of passengers in the car, thereby discriminating whether or not the congestion state in the car 4 is at the predetermined level described above ( Step S25). This level means that the car 4 is congested and a new person cannot get in.

  When the load determination unit 12 of the elevator control device 1 determines “NO” in the process of step S25, the function control unit 13 considers that the inside of the car 4 is not in a congested state where a person cannot newly enter, The process proceeds to step S6 and subsequent steps described in the first embodiment (steps S26 and S27).

  Further, when the function control unit 13 of the elevator control device 1 determines “YES” in the process of step S25, the function of the passenger car 4 is regarded as being in a congested state where a person cannot newly enter the first car. The process proceeds to step S8 and subsequent steps described in the embodiment (steps S28 to S33).

  As described above, in the elevator according to the second embodiment of the present invention, according to the photographing result of the car 4, the landing car 4 is congested and a new person cannot enter. If the hall call button 3 on the landing floor is operated before the door is closed, a new hall call after the departure of the car 4 is registered instead of performing the door opening control. As a result, a user who has not been able to get into the car 4 that has arrived can make a new hall call after the car 4 has departed, and can get on the car 4 that has arrived and depart. Since the user does not open the door again, the user can move to the destination floor smoothly.

(Third embodiment)
Next, a third embodiment of the present invention will be described. In addition, description of the same part as 1st Embodiment among the structures of the elevator which concerns on this embodiment is abbreviate | omitted.
FIG. 8 is a schematic diagram of various elevator hall devices according to a third embodiment of the present invention.

  In the first and second embodiments described above, the function when the single hall call button 3 on each floor is pressed before the departure of the car 4 is changed from the door opening control to a new function after the departure of the car 4 Although changed to hall call registration, in the third embodiment, as shown in FIG. 8, in addition to the first hall call button 3 for normal use, the second hall call button 23 for crowded use is provided on each floor. When the second hall call button 23 is pushed when the crowded state of the car 4 that has landed is in a state in which a new person cannot enter, instead of performing door opening control, New hall call registration after the departure of the car 4.

  The elevator car 4 according to the third embodiment includes a car load detecting device 5 as shown in FIG. The configuration of the elevator control device 1 for an elevator according to the third embodiment is the same as the configuration shown in FIG. However, the function control unit 13 does not change the function of the hall call button 3 as in the first embodiment, but does not change the function of the hall call button 3, and does not change the function of the hall call button 3. 23 operation is enabled.

Next, the processing operation of the elevator having such a configuration will be described. FIG. 9 is a flowchart showing an example of the processing operation of the elevator according to the third embodiment of the present invention.
First, it is assumed that the initial state is a normal time when it is not crowded. During normal times, the elevator control device 1 validates the operation of the first hall call button 3 for normal use on each floor, while invalidating the operation of the second hall call button 23 for congestion.

  And after the process of step S1 to S3 in 1st Embodiment (step S41, S42, S43), the input part 11 of the elevator control apparatus 1 inputs the detection signal from the car load detection apparatus 5 of the passenger car 4. The load discriminating unit 12 discriminates whether or not the load in the car 4 exceeds the predetermined reference value described above by comparing the load indicated by the detection result with a predetermined reference value. (Step S44).

  When the load determination unit 12 of the elevator control device 1 determines “NO” in the process of step S44, the function control unit 13 regards that the inside of the car 4 is not in a congested state where a new person cannot enter, If the first hall call button 3 on the floor on which the floor is landing is operated until the time has elapsed after the door is opened or the door 4 is closed by the door closing button operation and the car 4 leaves (step) In step S45, the control signal for door opening control is output to the car control device 4 via the output unit 14 in the same manner as the function of the conventional elevator. As a result, the car door and the hold door 2 are opened (step S46).

  In addition, when the function control unit 13 of the elevator control device 1 determines “YES” in the process of step S44, the function control unit 13 determines that the inside of the car 4 is in a congested state where a new person cannot enter. Therefore, the operation of the second hall call button 23 on the floor on which the floor is landing is validated, and the second hall call button 23 is blinked (step S47). Thereby, the passengers in the hall can recognize that the operation of the second hall call button 23 has become effective.

  When the blinking second hall call button 23 is operated (YES in step S48), the elevator control device 1 performs a new hall call registration after departure of the car 4 (step S49).

  In this case, the elevator control device 1 does not perform the door opening control unless the first hall call button 3 on the same floor or the door opening button in the car 4 are operated, and calls the other floors after the door is closed. After the car 4 is departed to respond, the car 4 is raised and lowered to respond to the hall call registered in step S49. In addition, the function control unit 13 invalidates the operation of the second hall call button 23 on the floor on which the user has landed.

  On the other hand, in a state where the blinking second hall call button 23 is not operated (NO in step S50), a predetermined time elapses after the door is opened or the door closing button in the car 4 is operated. In this case, the elevator control device 1 outputs a signal for door closing control to the car control device 6 via the output unit 14 and causes the car 4 to depart to respond to other floor calls.

  When the car 4 departs in this way (YES in step S50), the function control unit 13 turns off the second hall call button 23 that has been flashing on the floor where the user has been landing, The operation of the 2-hole call button 23 is invalidated again (step S51).

  After the operation of the second hall call button 23 becomes invalid, the load discriminating unit 12 of the elevator control device 1 detects that the passenger car 4 has landed again on the floor where the hall call button 3 is installed and opened the door. Based on the signal from the car load detection device 5, it is determined again whether or not the load in the car 4 exceeds the predetermined reference value.

  As described above, in the elevator according to the third embodiment of the present invention, the operation of the second hall call button 23 is effective when the landing car 4 is congested and a new person cannot enter. When this button is operated before the door is closed, a new hall call after departure of the car 4 is registered instead of performing the door opening control. As a result, a user who has not been able to get into the car 4 that has arrived can make a new hall call after the car 4 has departed, and can get on the car 4 that has arrived and depart. Since the user does not open the door again, the user can move to the destination floor smoothly.
