  Hereinafter, embodiments of the present invention will be described with reference to the drawings. This embodiment does not limit the present invention.

(First embodiment)
Fig.1 (a) is a schematic diagram which shows schematically the cage | basket | car of the elevator apparatus which concerns on 1st Embodiment. FIG. 1B is a schematic plan view of the periphery of the operation panel, and FIG. 1C is a front view corresponding to the plan view of FIG.

  As shown in FIG. 1A, a car door 11 is provided in the car 10 of the elevator apparatus 1. An operation panel 12 is installed around the car door 11. A driving device 14 and a motor 15 are installed on the upper portion of the car 10.

  As shown in FIG. 1C, the operation panel 12 is provided with a door opening / closing button 13 for the passenger 100 to operate the opening / closing operation of the car door 11. The door opening / closing button 13 includes an opening button 13a for opening the car door 11, and a closing button 13b for closing the car door 11. In the present embodiment, the minimum components of the elevator apparatus 1 are the car door 11 and the door opening / closing button 13.

  When, for example, a rush-in ride occurs in the elevator apparatus 1, the passenger 100 tries to press the open button 13a. However, since it is difficult to instantaneously distinguish between the open button 13a and the close button 13b, there is a high possibility that the passenger 100 will erroneously press the close button 13b. Therefore, the elevator apparatus 1 is provided with a door opening / closing control apparatus for preventing such an erroneous operation. Hereinafter, the door opening and closing control device according to the present embodiment will be described.

  FIG. 2 is a block diagram illustrating a configuration of the door opening / closing control apparatus according to the present embodiment. The door opening / closing control device 20 shown in FIG. 2 includes a projector 21, a light receiving sensor 22, a speed calculation unit 23, a speed determination unit 24, a button input unit 25, and a control unit 26. The speed calculation unit 23, the speed determination unit 24, the button input unit 25, and the control unit 26 are provided on the control panel 30.

  As shown in FIG. 1 (b), the projector 21 is located on one side of the operation panel 12 in the left-right direction (left side in the present embodiment) with respect to the door opening / closing button 13 when the door opening / closing button 13 is viewed from the front. is set up. Moreover, the light projector 21 has the some light source 121 arranged along the perpendicular direction, as shown in FIG.1 (c). Each light source 121 is configured by, for example, a laser light source that emits linear light 200.

  As shown in FIG. 1B, the light receiving sensor 22 is installed on the side plate 10 a of the car 10 that faces the projector 21. As shown in FIG. 1C, the light receiving sensor 22 has a plurality of photoelectric conversion elements 122. The plurality of photoelectric conversion elements 122 are individually opposed to the plurality of light sources 121 and arranged along the vertical direction. Each photoelectric conversion element 122 includes, for example, a photodiode that receives the light 200 emitted from the light source 121 and outputs a current corresponding to the light reception state to the speed calculation unit 23.

  The speed calculation unit 23 continuously detects changes in current output from the plurality of photoelectric conversion elements 122, respectively. Subsequently, the speed calculation unit 23 obtains the moving speed of the hand 101 of the passenger 100 that has moved between the projector 21 and the light receiving sensor 22 based on the detection result. Hereinafter, an example of a method for calculating the moving speed will be described.

  FIG. 3 is a graph for explaining an example of a moving speed calculation method. The graph shown on the upper side of FIG. 3 shows a change with time of the output current I1 of an arbitrary photoelectric conversion element 122 among the plurality of photoelectric conversion elements 122. On the other hand, the graph shown on the lower side of FIG. 3 shows a change with time of the output current I2 of the photoelectric conversion element 122 located closer to the door opening / closing button 13 than the arbitrary photoelectric conversion element 122. In other words, the output current I2 corresponds to the output current of the photoelectric conversion element 122 positioned above the arbitrary photoelectric conversion element 122.

  When the passenger 100 operates the door opening / closing button 13 on the bag, it is assumed that the hand 101 moves from the bottom to the upper side with respect to the door opening / closing button 13. Corresponding to the movement of the hand 101, as shown in FIG. 3, first, the output current I1 becomes smaller than the threshold current Ith, and then the output current I2 becomes smaller than the threshold current Ith. The speed calculation unit 23 moves the hand 101 based on the transition time T1 until the output currents I1 and I2 become smaller than the threshold current Ith and the preset distance between the photoelectric conversion elements 122. Find the speed. Subsequently, the speed calculation unit 23 outputs the obtained moving speed to the speed determination unit 24.

  Returning to FIG. 2, the speed determination unit 24 determines whether the moving speed exceeds a preset threshold value. Subsequently, the speed determination unit 24 outputs the determination result to the control unit 26.

  The button input unit 25 detects whether or not the open button 13a and the close button 13b of the door opening / closing button 13 are pressed. Subsequently, the button input unit 25 outputs the detection result to the control unit 26.

  The control unit 26 recognizes the current operation state of the car door 11 based on the detection result of the button input unit 25. Further, the control unit 26 outputs various signals to the drive device 14 based on the detection result of the button input unit 25 and the determination result of the speed determination unit 24.

  Hereinafter, the operation of the door opening and closing control device 20 will be described with reference to FIG. FIG. 4 is a flowchart showing an operation procedure of the door opening / closing control device 20.

  After the car door 11 starts to open and close (step S1), when an emergency situation occurs, such as a rush-in ride or clothing being pulled into the door pocket of the car door 11, the passenger 100 points toward the door open / close button 13 Move hand 101.

  The light 200 is blocked between the projector 21 and the light receiving sensor 22 by the operation of the hand 101. Therefore, the output current of each photoelectric conversion element 122 provided in the light receiving sensor 22 changes corresponding to the movement of the hand 101. Thereby, the hand 101 is detected (step S2).

  Next, the speed calculation unit 23 calculates the moving speed of the hand 101 based on the change in the output current of the photoelectric conversion element 122 (step S3). Subsequently, the speed determination unit 24 determines whether or not the moving speed calculated in step S3 exceeds a threshold value (step S4). Since the movement of the hand 101 during dredging is faster than the normal movement, there is a high possibility that the moving speed of the hand 101 exceeds the threshold value.

  When it is determined in step S4 that the moving speed has exceeded the threshold value, the control unit 26 outputs an inversion signal for inverting the current opening / closing operation of the car door 11 to the driving device 14 (step S5). When the car door 11 is performing the closing operation at the time of step S5, the driving device 14 switches the car door 11 from the closing operation to the opening operation based on the input of the reverse signal. Thus, for example, when a rush-in ride occurs, even if the passenger 100 accidentally presses the close button 13b, the car door 11 opens. Therefore, it is possible to prevent accidents caused by rushing on board.

  On the contrary, when the car door 11 is performing the opening operation, the driving device 14 switches the car door 11 from the opening operation to the closing operation based on the input of the reverse signal. Thereby, for example, when a situation occurs in which clothes or the like are pulled into the door pocket, the car door 11 is closed even if the passenger 100 erroneously presses the open button 13a. Therefore, it is possible to prevent an accident caused by pulling into the door pocket.

  The control unit 26 invalidates the operation of the door opening / closing button 13 for a certain period of time after outputting the inverted signal to the driving device 14 in step S5 (step S6). As a result, it is possible to prevent the passenger 100 from operating the door opening / closing button 13 incorrectly during the reversing operation. In step S6, the control unit 26 temporarily blocks input from the button input unit 25, for example.

  Thereafter, when a certain time has elapsed (step S7), the control unit 26 cancels the invalidation of the operation of the door opening / closing button 13 (step S8). However, if the fully open state or the fully closed state of the car door 11 is detected by a sensor (not shown) before the predetermined time has elapsed (step S9), the control unit 26 determines whether the door open / close button 13 is operated. Cancel invalidation.

  According to the embodiment described above, when the passenger 100 needs to operate the door opening / closing button 13 during the opening / closing operation of the car door 11, the door opening / closing control device 20 sets the movement speed of the hand 101 of the passenger 100. Based on this, the operation of the car door 11 is reversed by recognizing the operation at the time of dredging. This eliminates the need to instantaneously determine the open button 13a and the close button 13b of the door open / close button 13. Therefore, it is possible to take all possible measures against erroneous operation of the door opening / closing button 13.

(Second Embodiment)
FIG. 5 is a block diagram illustrating a configuration of a door opening / closing control device according to the second embodiment. The same components as those in the door opening / closing control device 20 according to the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 5, the door opening / closing control device 40 according to the present embodiment includes a light source 41 instead of the projector 21 and a light receiving panel 42 instead of the light receiving sensor 22. Furthermore, the door opening / closing control device 40 includes an extraction unit 43 and a recognition unit 44 provided in the control panel 30.

  Similar to the projector 21, the light source 41 is installed on the operation panel 12 on one side in the left-right direction with respect to the door opening / closing button 13 when the door opening / closing button 13 is viewed from the front. The light source 41 emits light radially. The light source 41 is composed of a light emitting element represented by, for example, an LED (Light Emitting Diode).

  FIG. 6 is a diagram schematically showing the layout of the light receiving panel 42. In the light receiving panel 42 shown in FIG. 6, a plurality of photoelectric conversion elements 412 are arranged in a matrix. In the present embodiment, each photoelectric conversion element 412 is configured by an LED that receives light from the light source 41 and outputs a current corresponding to the light receiving state. This LED has a characteristic of outputting a current corresponding to the amount of received light. In the present embodiment, paying attention to this characteristic, the LED is used as the photoelectric conversion element 412 of the light receiving panel 42.

  In the door opening / closing control device 40, when an object moves between the light source 41 and the light receiving panel 42, the light from the light source 41 is blocked by the object. When the photoelectric conversion element 412 of the light receiving panel 42 is the LED, the current output from each LED decreases. Thereby, the shadow of the object can be detected.

  The extraction unit 43 extracts shadow shape data of the object based on the current values individually output from the plurality of photoelectric conversion elements 412. Here, an example of a method for extracting shadow shape data will be described with reference to FIG.

  The extraction unit 43 compares the current value of each photoelectric conversion element 412 with a reference value set in advance, and recognizes the position of the photoelectric conversion element 412 whose current value is smaller than the reference value as a shadow. At this time, the extraction unit 43 recognizes the shade of the shadow by comparing the current value of each photoelectric conversion element 412 with a plurality of reference values in a stepwise manner. On the left side of FIG. 7, the shape data of the shadow of the hand 101 with the index finger extended is shown. On the other hand, in the center and the right side of FIG. The extraction unit 43 outputs the extracted shape data to the recognition unit 44.

  The recognizing unit 44 compares the shape data extracted by the extracting unit 43 with hand shape data registered in advance. At this time, the recognizing unit 44 calculates the matching rate indicating the degree of matching between the position of the shadow and the shade between the two shape data.

  If the matching rate is higher than a predetermined value, the recognition unit 44 recognizes the shape data extracted by the extraction unit 43 as hand shape data, and otherwise recognizes that the shape data is not hand shape data. The recognition unit 44 outputs the recognition result to the control unit 26. The control unit 26 outputs various signals to the driving device 14 based on the determination result of the speed determination unit 24 and the recognition result of the recognition unit 44.

  The operation of the door opening / closing control device 40 will be described below with reference to FIG. FIG. 8 is a flowchart showing an operation procedure of the door opening / closing control device 40.

  After the car door 11 starts to open and close (step S10), when the object moves between the light source 41 and the light receiving panel 42, the light receiving panel 42 blocks light reception according to the shape of the object. There are a plurality of photoelectric conversion elements 412. Based on the output currents of these photoelectric conversion elements 412, the extracting unit 43 extracts shape data indicating the shadow of the object (step S11).

  Next, the recognizing unit 44 obtains a matching rate between the hand shape data registered in advance and the shadow shape data. When the matching rate is higher than the predetermined value, the recognition unit 44 recognizes that the shadow is a hand (step S12).

  When the recognition unit 44 recognizes that the shadow is a hand, the speed calculation unit 23 calculates the moving speed of the shadow of the object (step S13). In step S13, the speed calculation unit 23 calculates the moving speed by the same method as in the first embodiment described above. Specifically, the speed calculation unit 23 determines the transition time until the output currents of two photoelectric conversion elements 412 adjacent in the column direction (vertical direction) or the row direction (horizontal direction) become smaller than the threshold current Ith. The moving speed is calculated based on T1 and a preset distance between these photoelectric conversion elements 412.

  When the speed calculation unit 23 calculates the movement speed as described above, the speed determination unit 24 then determines whether or not the movement speed exceeds a threshold value (step S14). When the moving speed exceeds the threshold value, operations similar to the operations from step S5 to step S9 described in the first embodiment are performed (steps S15 to S19).

  According to the present embodiment described above, the door opening / closing control device 40 obtains the moving speed of the hand when recognizing that the object moved between the light source 41 and the light receiving panel 42 is a hand. . Therefore, it is possible to grasp the movement of the hand with high accuracy. Therefore, it is possible to take more thorough measures against erroneous operation of the door opening / closing button 13.

(Third embodiment)
The configuration of the door opening / closing control device according to the present embodiment is the same as that of the door opening / closing control device 20 shown in FIG. Hereinafter, the operation of the door opening / closing control apparatus according to the present embodiment will be described.

  FIG. 9 is a flowchart showing an operation procedure of the door opening / closing control apparatus according to the present embodiment. In the present embodiment, when the car door 11 starts an opening / closing operation (step S21), operations similar to the operations from step S2 to step S4 described in the first embodiment are executed (steps S22 to S24).

  If it is determined in step S24 that the moving speed has exceeded the threshold value, the control unit 26 outputs a stop signal to the drive device 14 (step S25). The drive device 14 stops the opening / closing operation of the car door 11 based on the stop signal.

  After outputting the stop signal to the drive device 14, the control unit 26 invalidates the operation of the door opening / closing button 13 for a certain time (step S26). Thereafter, when a certain time has elapsed (step S27), the control unit 26 cancels the invalidation of the operation of the door opening / closing button 13 (step S28).

  According to the present embodiment described above, even when the passenger 100 does not instantaneously determine the open button 13a and the close button 13b of the door open / close button 13, the operation at the time of dredging is determined based on the moving speed of the hand 101. . Further, in the case of a dredging operation, the car door 11 stops the opening / closing operation. Therefore, when a rush-in boarding or a pull-in to the door pocket occurs, it is possible to prevent an erroneous operation of the door opening / closing button 13 and to avoid an accident caused by these.

  In addition, the structure of the door opening / closing control apparatus which concerns on this embodiment may be the same as that of the door opening / closing control apparatus 40 shown in FIG. In this case, the control unit 26 outputs a stop signal to the driving device 14 instead of the inversion signal when the moving speed exceeds the threshold value. Also in this case, since the opening / closing operation of the car door 11 is stopped, it is possible to avoid an accident caused by a rush-in ride or a pull-in to the door pocket.

(Fourth embodiment)
The configuration of the door opening / closing control device according to the present embodiment is the same as that of the door opening / closing control device 20 shown in FIG. Hereinafter, the operation of the door opening / closing control apparatus according to the present embodiment will be described.

  FIG. 10 is a flowchart showing an operation procedure of the door opening / closing control apparatus according to the present embodiment. In the present embodiment, when the car door 11 starts an opening / closing operation (step S31), operations similar to the operations from step S2 to step S4 described in the first embodiment are executed (steps S32 to S34).

  If it is determined in step S34 that the moving speed has exceeded the threshold value, the control unit 26 outputs a deceleration signal to the drive device 14 (step S35). The drive device 14 reduces the speed of the current opening / closing operation of the car door 11 based on the deceleration signal.

  After outputting the deceleration signal to the driving device 14, the control unit 26 invalidates the operation of the door opening / closing button 13 for a certain time (step S36). Thereafter, when a certain time has elapsed (step S37), the control unit 26 cancels the invalidation of the operation of the door opening / closing button 13 (step S38). However, if the fully open state or the fully closed state of the car door 11 is detected before the fixed time has elapsed (step S39), the control unit 26 controls the door opening / closing button 13 as in the first embodiment. Cancel the invalidation of the operation.

  Also in the present embodiment described above, even when the passenger 100 does not instantaneously determine the open button 13a and the close button 13b of the door open / close button 13, the operation during dredging is determined based on the moving speed of the hand 101. Further, in the case of a dredging operation, the opening / closing operation of the car door 11 is decelerated. Therefore, even if a rush-in boarding or a pull-in to the door pocket occurs, it is possible to prevent an erroneous operation of the door opening / closing button 13 and to avoid an accident caused by them.

  In this embodiment as well, the configuration of the door opening / closing control device may be the same as that of the door opening / closing control device 40 shown in FIG. In this case, the control unit 26 outputs a deceleration signal to the driving device 14 instead of the inversion signal when the moving speed exceeds the threshold value. As a result, the opening / closing operation of the car door 11 is decelerated, so that it is possible to avoid accidents caused by rush-in and pull-in to the door pocket.
