The hall call is registered according to the read information. Further, in the present technology, the wheelchair stop frame is divided into an upward direction and a downward direction, and an information reading device is provided for each, so that either one of the up and down directions is determined according to the stop frame selected by the wheelchair user. A hall call is registered. With this technology, a wheelchair user can register a hall call without operating a dedicated button.

JP 2009-298507 A

  According to the above prior art, the operation of the dedicated button is not necessary, but the wheelchair user needs to move and stop the wheelchair so that the IC tag is brought close to the information reading device. Further, depending on the stop position of the wheelchair, it is difficult to read information accurately, and it is necessary to adjust the position of the wheelchair. Furthermore, in order to select a call in the vertical direction, it is necessary to stop the wheelchair in the stop frame at a different position. Therefore, it is difficult to sufficiently improve the convenience depending on the conventional technology. Such a problem is the same when an IC tag is provided on a stick used by a visually impaired person and the above-described conventional technology is applied.

  Therefore, the present invention provides an elevator system that can sufficiently improve convenience when a wheelchair user or a visually impaired person registers an elevator hall call.

In order to solve the above problems, an elevator system according to the present invention includes a passenger detection device that detects a passenger using a sensor installed at a landing, and registers a hall call according to a detection result of the passenger detection device. If the passenger detection device detects a passenger entering a predetermined area at the landing, a guidance device is provided for guiding a predetermined movement of the passenger , and the passenger detection device is provided in the predetermined area at the landing according to the guidance of the guidance device. When it is detected that the passenger has made a predetermined movement , the hall call is registered.

  According to the present invention, a wheelchair user, a visually impaired person, and the like can easily register a hall call without operating a dedicated button. Thereby, the convenience at the time of a wheelchair user, a visually handicapped person, etc. using an elevator improves.

  Problems, configurations, and effects other than those described above will become apparent from the following description of embodiments.

1 is a schematic diagram illustrating an overall configuration of an elevator system according to an embodiment of the present invention. It is a top view of the elevator hall in the floor where a camera is provided. The operation | movement flow of an elevator control apparatus is shown. The top view of the hall of the elevator system which is a modification of embodiment of FIG. 1 is shown. The top view of the hall of the elevator system which is the other modification of embodiment of FIG. 1 is shown. The photoelectric sensor installation part in the modification of FIG. 5 is shown.

  FIG. 1 is a schematic diagram showing an overall configuration of an elevator system according to an embodiment of the present invention.

  In the present embodiment, the car 101 suspended by the rope 103 in the hoistway surrounded by the hoistway wall 111 serves the A floor, the B floor, and the C floor. The hall-side call buttons 110-A, 110-B, and 110-C for registering hall calls for dispatching the cars 101 are provided at the halls on each floor. The landing-side call button includes an upward call button and a downward call button. When one of the buttons is pressed by a passenger, a landing call signal is transmitted to the elevator controller 104. When the hall call signal is received and the hall call is registered, the elevator control device 104 turns on the lighting device of the pressed hall-side call button to display that the call has been registered, and by a driving device (not shown) By driving the rope 103, the car 101 is dispatched to the floor corresponding to the registered hall call.

  In the present embodiment, in addition to call registration by the hall-side call button, the hall call can be registered by detecting the movement of the passenger 108 based on the hall image acquired by the camera 109 as follows. it can. In addition, although the camera 109 with which the passenger detection apparatus in this embodiment is provided is provided in all the floors in a figure, it demonstrates as being provided in the A floor for the sake of simplicity.

  When the passenger 108 who is a wheelchair user enters a predetermined area at the landing, that is, the area where the passenger recognition frame 106 is displayed on the floor surface in the present embodiment, the elevator control device 104 acquires the camera 109. The image of the predetermined area is subjected to image processing to detect the passenger 108 entering the predetermined area. In this image processing, the passenger 108 is detected by detecting a difference between an image of a predetermined area stored in the memory 105 included in the elevator control device 104 when there is no passenger and an image acquired by the camera 109. To do. At this time, the image feature amount in the case of a wheelchair user is specified in advance and stored in the memory 105, and the acquired image feature is collated with the stored feature amount to get on the wheelchair. You may detect that it is a passenger. When the passenger 108 is detected, the elevator control device 104 controls the guide device 107 to guide the passenger 108 to make a predetermined movement. For example, the present guidance indicates that when a downward call is registered, it is lowered rearward, that is, away from the elevator landing door, and when an upward call is registered, it is instructed that it has stopped without moving. This guidance is executed by audio broadcasting or image display.

  After the guidance, the elevator control device 104 performs image processing on an image of a predetermined area including the passenger 108 acquired by the camera 109, and determines whether the passenger 108 has performed a predetermined movement according to the guidance. In the main image processing, a predetermined movement of the passenger 108 is detected based on a time change of the camera image before and after the guidance or after the guidance. When a predetermined movement of the passenger 108 is detected, the elevator control device 104 registers a downward hall call on the floor where the passenger 108 is located. When the predetermined movement of the passenger 108 is not detected, that is, when it is detected that the passenger 108 is stopped, the elevator control device 104 registers an upward hall call on the floor where the passenger 108 is located. When the hall call is registered, the elevator control device 104 turns on the lighting device for the hall-side call button corresponding to the registered call direction in the same manner as when the hall-side call button 110-A is pressed. The car 101 is dispatched to the floor corresponding to the registered hall call.

  The elevator control device 104 determines that the call registered by the movement of the passenger 108 as described above is a dedicated call by the wheelchair user, and sets the door closing speed to the car to be dispatched more than usual, that is, the landing. Communication that installs a dedicated operation command that makes the call later than when the side call button 110-A is pressed and the call is registered, or a dedicated operation command that makes the door opening time longer than usual. The information is transmitted to the door control device (not shown) provided in the car via the device 102. Further, the elevator control device may transmit a command for displaying in the car that the dedicated call has been registered to a display control device (not shown) provided in the car 101 via the communication device 102. .

  FIG. 2 is a plan view of the elevator hall on the floor (A floor) where the camera provided in the passenger detection device in FIG. 1 is provided.

  The camera 109 is provided at a position where an image of an area including the rectangular passenger recognition frame 106 displayed on the floor surface can be acquired on the landing. When the passenger 108 using the wheelchair enters the passenger recognition frame 106, as described above, the elevator control device 104 performs image processing on the image of the passenger 108 acquired by the camera 109, thereby giving an announcement and landing to the passenger. Perform call registration. Further, as described above, the elevator control device 104 lowers the door closing speed of the landing door 201 and the car door (not shown) from when the car arrives at the landing to the departure, and increases the door opening time. A command is transmitted to the door control device so that it is longer than usual.

  The guidance device 107 is installed at a position where the passenger 108 who has entered the passenger recognition frame 106 can sufficiently grasp the guidance, that is, a position where sound can be heard for audio broadcasting, and a position where an image can be seen for image display. The In the present embodiment, the guide device 107 is provided on the landing side surface of the hoistway wall 111 as shown in FIG.

  In addition, the passenger recognition frame 106 is displayed by drawing on a floor surface with a paint, or sticking a tape on a floor surface. In addition, a light emitting element such as an LED may be provided on the floor portion for display. In addition, the passenger recognition frame 106 is not limited to a rectangular shape, and may be a shape of two parallel lines indicating front and rear or a left and right range of a predetermined area.

  According to the present embodiment, since the call is registered by a predetermined motion, that is, a motion that stops and moves backward, the call can be registered without operating the landing side call button. And since it is a rough movement of only back, without designating the moving position and distance, a passenger is not burdened in order to register a call. In addition, if a passenger enters one passenger recognition frame, that is, a predetermined area, the passenger can select a vertical direction and register a hall call. Therefore, convenience for passengers is improved. In addition, since the movement of the passenger 108 is detected by image processing, if the movement moves backward, the movement distance and direction can be given freedom, so the movement of the passenger is detected with high accuracy. Call registration. Further, in the present embodiment, by providing the passenger recognition frame 106, the passenger detection device can easily guide the passenger to a predetermined area where the passenger can be detected, and limit the range for detecting the passenger, thereby detecting the passenger. Accuracy can be improved. In addition, it detects the passenger's entry into the predetermined area and announces the predetermined movement for registering the call, so that the passenger can be surely registered with the predetermined movement and used for the first time. Passengers are prevented from being confused and the convenience of the passengers is improved.

  FIG. 3 shows an operation flow of the elevator control device 104 in the present embodiment.

  When the passenger 108 who uses a wheelchair enters the passenger recognition frame 106 on the floor A side and detects the entrance of the passenger 108 based on the image acquired by the camera 109 (S301), the guidance device 107 transmits an audio broadcast. For example, a predetermined movement for registering a call is guided to the passengers by a broadcast saying “If you go up, please wait at that place. If you go down, please go back.” (S302).

  After the guidance in step S302, it is determined whether or not passenger movement is detected (S303). In step S303, if no passenger movement is detected for a certain period of time, for example, 3 seconds later (N), an upper call is registered (S304). If a passenger movement is detected in step 303 (Y), it is determined whether the passenger movement is a backward movement (S307). If it is detected in step S307 that the passenger has moved outside the rear (N), it is determined that the passenger is not an elevator passenger, the call is not registered (S309), and the operation is terminated (S306). In step S307, when a backward movement of the passenger is detected (Y), a lower call is registered (S308).

  When step S304 or S308 is executed and one of the upper and lower calls is registered, the lighting device of the corresponding landing side call button 101-A is turned on, and the arrival of the elevator responding to the call is output from the guidance device 107. The prediction is made by voice guidance (S305). For example, when an upper call is registered, an announcement “I will go up” is announced, and when a lower call is registered, an announcement “I will come down” is announced. When step S305 is executed, the operation is terminated (S306).

  If the wheelchair user has received an explanation in advance about the call registration method at the landing as described above, or if it is always displayed on the landing, the step 302 can be omitted, or a chime can be substituted for the guidance broadcast. The passenger may be informed that the vehicle has entered the predetermined area by ringing. Further, in step S305, the arrival of the elevator may be predicted by turning on an upward or downward hall lantern or sounding a chime. When a chime is sounded, the number of sounds may be changed between an upward call and a downward call or the chime tone may be changed to notify the passenger of which direction is registered in the vertical direction. Moreover, you may alert | report a passenger only by lighting the hall side call button.

At this time, by detecting the presence or absence of reflected light or temporal changes in the presence or absence of reflected light based on signals output from a plurality of photoelectric sensors, passengers enter, stop, and move backwards to detect guidance broadcasts and hall calls. Registration is performed. Here, the photoelectric sensor is provided outside the passenger recognition frame as in the present modification, or provided directly below the passenger recognition frame, so that visible light or infrared light can be reliably transmitted to the passenger located in the passenger recognition frame. , And the reflected light can be detected.

  FIG. 6 shows a photoelectric sensor installation portion in the modification of FIG. The photoelectric sensor 400 is embedded under the floor surface 500. A lid 401 made of a plate material that transmits visible light or infrared light is provided on the photoelectric sensor to eliminate a step from the floor surface 500 and to protect the photoelectric sensor 400 from dust and the like. Further, the photoelectric sensor 400 is supported by the support member 402 so that the optical axis thereof faces the passenger.

  According to the modification of FIG. 4, the convenience of the wheelchair user who uses the elevator is improved as in the above-described embodiment. Further, by using the photoelectric sensor, the movement of the passenger can be detected by relatively simple data processing, the passenger detection device can be downsized, and the degree of freedom of the installation location is improved.

  The present invention is not limited to the above-described embodiments and modifications, and includes various other modifications. For example, the above-described embodiments and modifications have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
