  ADVANTAGE OF THE INVENTION According to this invention, the transport efficiency of the user by an elevator can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an elevator system according to an embodiment of the present invention, and FIG. 2 is a diagram showing an elevator state table.

  As shown in FIG. 1, this elevator system is provided on the floors of the elevator platforms, surveillance cameras 1a, 1b, 1c as first surveillance cameras, door opening / closing sensors 2, cars, and each stop floor. A door opening / closing mechanism 3, a memory 4 as a storage device in which an elevator state table 20 is stored, message indicators 6a, 6b, 6c as guide means, a car stop floor button 7, an elevating mechanism 8, A car call button 9a, 9b, 9c provided on the wall surface of each floor and a control device 10 for controlling these devices are provided. A car refers to a containment room in which a user is boarded.

  The surveillance cameras 1a, 1b, and 1c are provided on the elevator floor. The surveillance cameras 1a, 1b, and 1c are imaging means for imaging the elevator hall, and are, for example, CCD cameras.

  The door opening / closing mechanism 3 is a device that opens and closes the door of the car. For example, the door opening / closing mechanism 3 includes a motor, an actuator, and the like that drive the door. The door opening / closing sensor 2 detects that the door of the car has been opened or closed by the door opening / closing mechanism 3 and notifies the control device 10 of it.

  The memory 4 is a memory that can store, for each floor, the pressing state of the stop floor button 7 in the car, the pressing state of the car call buttons 9a, 9b, 9c... On each stop floor, and the number of passengers waiting for elevators detected by face recognition. Device.

  The message displays 6a, 6b, 6c are provided at the upper part of the door opening / closing part of the elevator platform on each floor. The message display devices 6a, 6b, and 6c are controlled by the control device 10 to display a message that the car is stopped or passed on this floor.

  The in-car stop floor button 7 is provided for the number of floors on the wall surface in the car on which the user is boarded. The in-car stop floor button 7 is a stop floor designating button for the passenger to designate the stop floor of the car, and is connected to the control device 10.

  The elevating mechanism 8 is an apparatus that elevates and lowers the car, and includes, for example, a motor, a pulley, a belt, and cables, and the elevating operation is controlled by the control device 10. Controlled devices whose operations are controlled by the control device 10 such as the lifting mechanism 8 and the door opening / closing mechanism 3 are referred to as elevator devices.

  The car call buttons 9a, 9b, 9c... Are provided on the wall surface of the elevator hall on each floor. Car call buttons 9 a, 9 b, 9 c... Are buttons that are pressed by a person waiting for boarding to stop the car on this floor, and are connected to the control device 10.

  The car call buttons 9a, 9b, 9c,... Are composed of an upward button and a downward button, and each button is provided with a lamp. When the user presses the button in each direction, the lamp is turned on and off. Further, the car call buttons 9a, 9b, 9c,... On each floor are canceled when the number of boarding waiting persons on the floor is determined to be “0” as a result of the processing of detecting the number of waiting passengers by the control device 10.

The control device 10 recognizes one person's face included in the image one by one by processing the images of the elevator hall imaged by the monitoring cameras 1a, 1b, 1c. The total number is obtained by adding the number of persons, and the number of people waiting to board is detected.
The control device 10 updates the corresponding information in the memory 4 every time the number of passengers waiting to be detected is detected and each time the above-described buttons (the car call buttons 9a, 9b, 9c... And the car stop floor button 7) are pressed. Functions as an updating means. For example, the control device 10 sets the number of people waiting for boarding in the column of the number of people waiting for boarding in the elevator status table 20 of the memory 4 every time the number of people waiting for boarding is detected, that is, updates the number of people waiting for boarding in the status table 20 of the elevator.

  The control device 10 stops the car on each floor according to the number of people waiting for boarding, the state of the car call buttons 9a, 9b, 9c..., And the state of the stop floor button 7 in the car. It is determined whether or not to pass, and the lifting mechanism 8 is controlled according to the determination result.

  The control device 10 determines that the state of the car call button (the corresponding button of the car call buttons 9a, 9b, 9c,...) On the stop floor to which the car is heading in the elevator state table 20 is “pressing” and stops in the car. When the state of the floor button 7 is “not pressed” and the number of waiting passengers on the floor is updated to “0”, the pressed state of the car call button on the floor is canceled and the floor passes. The ascending mechanism 8 is controlled so that the

  As a technique for obtaining the number of people waiting for boarding from an elevator hall image, for example, a technique for obtaining the number of faces of people waiting for boarding by performing face recognition from an image, for example, a so-called face recognition technique is used.

  The control device 10 recognizes the face of a person from the images of the elevator hall imaged by the monitoring cameras 1a, 1b, 1c,... To determine the number of faces and detects the number of people waiting to board.

  As shown in FIG. 2, the elevator status table 20 includes the number of people waiting for a car (0 when there is no one), car call button states ("pressed", "-" (not pressed)), stop floor The button state (“pressed”, “−” (not pressed)) or the like is set according to the monitoring result of each device of the control device 10.

  That is, the elevator state table 20 is a table in which the boarding state and the button press state are set for each stop floor.

The operation of the elevator system according to the first embodiment will be described below with reference to FIGS.
In the case of this elevator system, as shown in FIG. 3, the control device 10 always performs a monitoring process while the elevator is in operation, and reflects the monitoring result in the elevator state table 20 (step S101). Details of the monitoring process will be described later with reference to the flowchart of FIG.

  The control device 10 stops the car on each floor, controls the door opening / closing mechanism 3 to open the door of the car, and checks the elevator state table 20 each time it is detected by the door opening sensor 2. It is determined whether or not the stop floor button state is “pressing” (step S102).

  As a result of the determination, if the stop floor button state in the car is not “pressing” (No in step S102), the control device 10 checks the elevator state table 20, and the car call button state is “ It is determined whether it is “pressed” (step S102).

  As a result of the determination, if the car call button on the other floor, for example, the next floor (next floor) is not “pressed” (No in step S103), the control device 10 displays the message display device (message A message such as “This floor will pass” is displayed on the display 6a, 6b, 6c..., And the elevator (car) is allowed to pass through the floor without stopping (step S104). ).

  Further, in the determination process in step S102, when the elevator state table 20 is checked, if the stop floor button state in the car on the next floor is "pressing" (Yes in step S102), the control device 10 Displays a message such as "Elevator will stop" on the message display on the stop floor (the one on the corresponding one of the message displays 6a, 6b, 6c ...) and the elevator that has reached the stop floor The (car) is stopped (step S105), and the car door and the landing door are opened (step S106).

  After the door is opened, the passenger gets out of the car, the person waiting for boarding gets into the car, and when a predetermined time (several seconds) elapses, the control device 10 controls the door opening / closing mechanism 3 to close the door, and the lifting mechanism 8 To raise and lower the car to the next floor.

  Next, the monitoring process in step S101 will be described in detail with reference to the flowchart in FIG. When entering the monitoring operation, the control device 10 always monitors whether or not the call buttons 9a, 9b, 9c,... On each floor are pressed (step S201).

  As a result of this monitoring, when the call buttons 9a, 9b, 9c... Are pressed (Yes in step S201), the control device 10 lights the pressed call buttons 9a, 9b, 9c.

  In addition, the control device 10 obtains the number of people from the images captured by the monitoring cameras 1a, 1b, and 1c on each floor and monitors the number of people waiting for boarding (step S203). The table 20 is updated (step S204).

  After the update, the control device 10 checks the number of passengers waiting for the next floor to stop in the elevator status table 20 at a predetermined timing. The predetermined timing is, for example, when the door opening / closing sensor 2 detects the opening of the car door.

  As a result of this check, when the number of passengers waiting for the next floor to stop is not “0” (No in step S205), the control device 10 determines whether the car has arrived on the floor (step S206) and then opens and closes the door opening / closing mechanism. 3 to open the door of the car, and when the door opening / closing sensor 2 detects the opening of the door (step S207), the monitoring camera on that floor (for example, the monitoring camera 1c if the stop floor is the third floor) The monitoring operation is stopped (step S208), and the call button 9c on that floor is turned off (step S209).

  As a result of the check, if the number of passengers waiting for the next floor to stop is “0” (Yes in step S205), the control device 10 can monitor the floor (for example, the stop floor is the third floor). In this case, the monitoring operation of the monitoring camera 1c) is stopped (step S208), and the car call button 9c on the floor is turned off (step S209).

  That is, even if the car call button 9c is pressed once, if the number of people waiting for boarding in the elevator status table 20 is “0”, that is, there is no user at the elevator hall, the control is performed. The device 10 automatically cancels the car call and turns off the car call button 9c.

  Here, an example of the above operation will be described. In this system, at the timing when the car call buttons 9a, 9b, 9c... Installed at the elevator halls on each floor are pressed, the images obtained from the monitoring cameras 1a, 1b, 1c. The number of people is detected and reflected in the table 20. This video monitoring process is performed until the door is opened after the car stops on the floor.

  For example, when the elevator car descending from the upper floor stops on the third floor, the information on the next floor of the elevator status table 20, that is, the second floor, as shown in FIG. When the call button is “pressing” and the stop floor button is “−” (not pressed), the control device 10 determines that the car is stopped on the second floor at this time. When the stop floor button is “pressed”, it is determined that the stop floor is stopped regardless of the state of the call button.

  Thereafter, as shown in FIG. 6, when the person P waiting for boarding leaves the call button 9b at the elevator hall on the second floor without releasing the call button 9b, the control device 10 As a result of processing the video obtained from 1b, the number of people waiting to board is detected as 0, and the corresponding column of the elevator status table 20 is updated as “0” as shown in FIG.

  At this time, the control device 10 determines that the car is not stopped on the second floor unless the state of the stop floor button 7 in the car is “pressing”, and as shown in FIG. A message such as “This floor will pass” is displayed on the message display 6b, and the call button 9b is turned off, and the elevator (car) is passed through the second floor.

  As described above, according to the elevator system of the first embodiment, the system knows the number of people waiting for boarding on each floor using the images of the monitoring cameras 1a, 1b, 1c,. Since the call at the floor where there is no waiting user is automatically canceled (invalidated) and the elevator is allowed to pass, the transportation efficiency of the user by the elevator can be improved.

  Next, a second embodiment will be described. In the description of the second embodiment, the same reference numerals are given to the same components as those in the first embodiment, and the description thereof is omitted.

  In the case of the elevator system according to the second embodiment, as shown in FIG. 8, the configuration of the first embodiment further includes a monitoring camera 5 as a second monitoring camera.

  The surveillance camera 5 is a camera installed on the upper part of the inner wall surface of the car, and a CCD camera or the like is used similarly to the surveillance cameras 1a, 1b, 1c.

  Further, as shown in FIGS. 11 and 12, for example, the elevator status table 20 includes the number of people waiting for a car (“0” when there is nobody), car call button states (“pressing”, “−” ( (Not pressed)), stop floor button state in car ("pressing", "-" (not pressed)), current number of passengers (... people), capacity (for example, 2 people, etc.) are stored (set) )

  The current number of passengers (... people) is the number of people currently in the car, and is the number of passenger faces obtained by performing image processing (face recognition processing) on the video taken by the surveillance camera 5. is there. The capacity is the number of passengers that can be boarded in the car and is a fixed value.

  In this case, the control device 10 obtains the number of faces by recognizing a person's face by processing the images of the elevator hall imaged by the surveillance cameras 1a, 1b, 1c. It functions as a boarding waiting number detecting means for detecting

After stopping the car, the control device 10 opens the door, and when the door is closed after a predetermined time, the control device 10 performs image processing on the image in the car imaged by the monitoring camera 5 and displays the face of the person in the car. The number of faces is recognized to detect the number of passengers in the car.
Each time the number of passengers waiting in the elevator hall and the number of passengers in the car are detected, the control device 10 presses the above buttons (car call buttons 9a, 9b, 9c... And car stop floor button 7). It functions as an updating means for updating the information in the memory 4 each time.
Specifically, every time the number of passengers is detected, the control device 10 sets the number of passengers in the column of the number of passengers in the elevator status table 20 in the memory 4, that is, updates the number of passengers in the elevator status table 20. To do.

  When the car heads to the stop floor, the control device 10 displays the number of passengers waiting in the elevator status table 20 in the memory 4, the number of passengers in the car, and the pressed state of the car call buttons 9a, 9b, 9c. It determines whether to stop or pass the car to the corresponding stop floor according to the pressed state of the stop floor button 7 in the car, and functions as a control means for controlling the ascending mechanism 8 according to the determination result.

  For example, when the state of the call button on the stop floor to which the car is heading is “pressing” and the state of the stop floor button in the car is “not pressed” in the elevator status table 20 of the memory 4 When the number of passengers waiting on the floor is added to the number of passengers in the car, if the number of passengers exceeds the preset capacity, message passing machines 6a, 6b, 6c,. At the same time, the ascending mechanism 8 is controlled so as to allow the car to pass on the corresponding floor.

  Hereinafter, the operation of the elevator system according to the second embodiment will be described with reference to FIGS. First, the sequence operation of this elevator system will be described with reference to the flowchart of FIG.

  In this case, as shown in FIG. 9, the control device 10 always performs a monitoring process while the elevator is in operation, and reflects the monitoring result in the elevator state table 20 (step S <b> 301).

  During the monitoring, the control device 10 checks the elevator state table 20 and determines whether or not the number of people waiting for boarding on the next floor is “0” (step S302).

  As a result of the determination, if the number of people waiting to be boarded on the next floor is “0” (Yes in step S302), then the control device 10 indicates that the stop floor button state in the elevator state table 20 is “pressed”. Is determined (step S303).

  As a result of this determination, when the stop floor button state in the car is “pressing” (Yes in step S303), the control device 10 determines whether the message display machines (message display machines 6a, 6b, 6c... A message such as “Elevator stops” is displayed on the floor (step S304), the elevator (car) that has reached the stop floor is stopped (step S305), and the car door is opened. (Step S306).

  Further, if the number of passengers waiting for the next floor is not “0” as a result of checking the elevator state table 20 in the determination process of step S302 (No in step S302), the control device 10 determines the current number of passengers. The number of people waiting to be boarded on the next floor is added, and it is determined whether or not the number of added passengers exceeds the capacity, that is, whether or not the capacity is over (step S308).

  If the result of this determination is that the capacity is over (Yes in step S308), or there is no waiting for boarding (No in S302), and the stop floor button state in the car is not “pressing” (No in step S303). The control device 10 displays a message such as “This floor will pass” on the message display on the next floor (the one on the corresponding one of the message displays 6a, 6b, 6c...) (Step S309). The elevator (car) is allowed to pass through the floor without stopping (step S310).

  In addition, as a result of the above determination, when the number of persons after the addition is equal to or less than the capacity and does not exceed the capacity (No in Step S308), the control device 10 causes the control device 10 to display a message display (message display) on the next floor A message such as “Elevator will stop” is displayed on the machines 6a, 6b, 6c... (Step S304), and the elevator (car) that has reached the stop floor is stopped (step S304). In step S305, the car door and the landing door are opened (step S306).

  Here, an example of the above operation will be described. In this system, at the timing when the car call buttons 9a, 9b, 9c,... Installed in the elevator halls on each floor are pressed, the control device 10 processes images obtained from the monitoring cameras 1a, 1b, 1c,. Thus, the number of people waiting to board is detected and reflected in the table 20. This video monitoring process is performed while descending from the previous floor and until the door is opened after the car stops on the floor. Then, when the descent starts again, the monitoring operation of the image of the next floor platform is resumed.

  When the elevator car is descending from the fourth floor to the third floor, for example, the information on the third floor of the elevator status table 20 indicates that the number of waiting cars is “1” and the car call button is “pressed” as shown in FIG. When the stop floor button is “−” (not pressed) and the current number of passengers is “1”, the control device 10 does not reach the capacity of two passengers at this time, so It is determined to stop on the 3rd floor.

  Then, when the car arrives on the third floor, stops the car, and opens the door, as shown in FIG. 10, the passenger P who has been waiting for boarding enters the car and is already in the car. Together with “2” people, that is, the capacity is full.

After a predetermined time from opening the door, the control device 10 controls the door opening / closing mechanism 3 to close the door.
Then, since the control device 10 detects that the door of the car is closed by the door opening / closing sensor 2, the control device 10 uses this as a trigger for the image obtained from the monitoring camera 5 in the car. Face recognition processing is performed to determine the number of faces in the car, and the number of passengers in the car is detected. In this example, the number of passengers in the car is “2”, and this number is reflected in the current number of passengers in the elevator status table 20.

  Thereafter, the control device 10 checks the elevator status table 20 in the memory 4 when lowering the car on the third floor to the second floor, and the information on the next floor, that is, the second floor, as shown in FIG. When the number of waiting cars is “1”, the car call button is “pressing”, the stop floor button is “−” (not pressed), and the current number of passengers is “2”, the control device 10 at this time Since the number of people has reached the capacity, it is determined that the car is allowed to pass on the second floor.

  Therefore, in this case, the control device 10 displays the message “This floor will pass” on the message display 6b on the second floor (see FIG. 10).

  At the elevator floor on the second floor, there is one user P waiting for boarding, but the car passes on the second floor without stopping because of the capacity limit.

  As described above, according to the elevator system of the second embodiment, the number of passengers in the car using the monitoring cameras 1a, 1b, 1c,... Installed on each floor and the monitoring camera 5 installed in the car. The number of passengers waiting on the next floor is added to determine whether or not the number of passengers exceeds the capacity. If the number of passengers exceeds the capacity, control is performed so that the passenger can pass the floor, so that the user can get on even if the elevator (car) stops. It is possible to avoid such a situation. In addition, the number of stops on the middle floor is reduced, so that a user on the car can be transported quickly to the target floor, and the transportation efficiency of the user can be improved.

  In addition, this invention is not limited only to the said embodiment, You may deform | transform a component in the range which does not deviate from the summary in an implementation stage. In addition, various inventions can be configured by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.

  Specifically, in the above-described embodiment, the surveillance camera 5 installed in the car is used to shoot video for face recognition processing. However, the surveillance camera 5 is installed, for example, on the ceiling portion of the car.
