It is a flowchart which shows a series of operation | movement of the elevator apparatus in Embodiment 1 of this invention.

  Hereinafter, an elevator apparatus according to the present invention will be described with reference to the drawings according to a preferred embodiment.

Embodiment 1 FIG.
FIG. 1 is a configuration diagram of an elevator apparatus according to Embodiment 1 of the present invention. In FIG. 1, the elevator apparatus includes a car 10, a multi-beam sensor 20, an elevator control unit 30, and a car call registration unit 40. FIG. 1 shows a state in which the car 10 is stopped at the floor where the hall call is generated and the door (not shown) for opening and closing the entrance 11 of the car 10 is completely open.

  A multi-beam sensor 20 including a plurality of light emitting elements 20a and a plurality of light receiving elements 20b is provided at the side end of the entrance / exit 11 of the car 10. Specifically, a plurality of light emitting elements 20a are fixed to one side end of the entrance / exit 11, and a plurality of light receiving elements 20b are fixed to the other side end of the entrance / exit 11.

  In addition, the multi-beam sensor 20 detects light shielding information of passengers passing through the entrance / exit 11. In FIG. 1, a state in which the beam emitted from each light emitting element 20a is incident on each light receiving element 20b is also illustrated using an arrow dotted line.

  The elevator control unit 30 includes a passenger image generation unit 31, a guide dog user determination unit 32, and a travel control unit 33. Moreover, the passenger image generation part 31 acquires the detection result by the multi-beam sensor 20, and produces | generates the passenger image (1st passenger image) showing the characteristic of the passenger who passes the entrance / exit 11.

  The guide dog user determination unit 32 determines whether or not the passenger boarding the car 10 is a guide dog user based on the passenger image generated by the passenger image generation unit 31. The traveling control unit 33 controls traveling of the car 10 in the hoistway according to car call registration performed by a car call registration unit 40 described later.

  The car call registration unit 40 is provided in the car 10 and is operated by a passenger in the car 10 to perform car call registration for causing the car 10 to travel to a desired floor. Specifically, the car call registration unit 40 has a button corresponding to each floor, and passengers in the car 10 go to that floor by pressing the button corresponding to the desired floor. Can do.

  In addition, the car call registration unit 40 is set in advance even if the guide dog user does not press the button of the car call registration unit 40 when the guide dog user determination unit 32 determines that the passenger is a guide dog user. Register a specific car call. That is, even if the guide dog user in the car 10 does not operate the car call registration unit 40, the desired car call registration is automatically performed.

  Here, the specific car call registration means car call registration dedicated to guide dog users different from general users who need to operate the car call registration unit 40. For example, if a guide dog user gets into the car 10 from the entrance floor (lobby floor), the car call registration for running the car 10 to the floor (residence floor) where the guide dog user resides is specified. You can set it as car call registration. Further, when the guide dog user gets on the car 10 from the residence floor, the car call registration for running the car 10 to the entrance floor may be set as the specific car call registration. In addition, about the setting example of specific car call registration, it is not limited to what was mentioned above, What is necessary is just to make the setting according to the guide dog user who uses an elevator suitably.

  In this way, if the passenger in the car 10 is a guide dog user, the car 10 travels according to the specific car call registration that is automatically performed without operating the car call registration unit 40. Improved convenience.

  Next, operations of the passenger image generation unit 31 and the guide dog user determination unit 32 according to the first embodiment will be described with reference to FIG. FIGS. 2A and 2B are explanatory diagrams illustrating an example of a passenger image generated by the passenger image generation unit 31 of the elevator apparatus according to Embodiment 1 of the present invention.

  In FIG. 2B, as in a general multi-beam sensor, a row corresponds to a beam emitted from each light emitting element of the multi-beam sensor 20, a column corresponds to a detection period, and each column corresponds to an entrance / exit. 11 corresponds to the shading information of passengers passing through No. 11. Further, the blacked out column represents the detection result that the beam is not incident on the light receiving element 20b, and the blacked out column represents the detection result that the beam is incident on the light receiving element 20b.

  Here, it is assumed that the guide dog user gets into the car 10 as shown in FIG. In this case, if the detection cycle of the multi-beam sensor 20 is appropriately set, the passenger image generation unit 31 generates the passenger image shown in FIG. 2B based on the detection result of the multi-beam sensor 20. Moreover, the area | region filled with the black of the passenger image shown in FIG.2 (b) shows the pair of guide dog user and guide dog.

  The guide dog user determination unit 32 determines whether the passenger is a guide dog user based on the passenger image generated by the passenger image generation unit 31. Specifically, for example, a reference image of a guide dog user and a guide dog pair may be set in advance, and the above determination may be made by comparing the passenger image with the reference image. Moreover, since the height of one column of the passenger image shown in FIG. 2B corresponds to the distance between the light emitting elements (between the light receiving elements), the height of the area of the passenger image that is painted black is estimated. Thus, the above determination may be made. In this manner, the guide dog user determination unit 32 determines whether the passenger is a guide dog user from the passenger image using a known image analysis technique.

  Next, a series of operations of the elevator apparatus according to the first embodiment will be described with reference to the flowchart of FIG. FIG. 3 is a flowchart showing a series of operations of the elevator apparatus according to Embodiment 1 of the present invention. Note that this flowchart may be executed, for example, when the car 10 stops at the floor where the hall call occurs and the door of the car 10 opens.

  In step S101, the passenger image generation unit 31 acquires a detection result detected by the multi-beam sensor 20 as the passenger passes through the entrance / exit 11, generates a passenger image, and proceeds to step S102.

  In step S <b> 102, the guide dog user determination unit 32 determines whether the passenger is a guide dog user based on the passenger image generated by the passenger image generation unit 31.

  And the guide dog user determination part 32 complete | finishes a series of processes, when it determines with a passenger not being a guide dog user (namely, NO). In this case, since the passenger is not a guide dog user, the specific car call registration is not performed by the car call registration unit 40, and the car call registration is performed by the passenger operating the car call registration unit 40.

  On the other hand, when it is determined that the passenger is a guide dog user (that is, YES), the guide dog user determination unit 32 proceeds to step S103.

  In step S103, the car call registration unit 40 performs specific car call registration and ends the series of processes. In this case, since the car 10 travels according to the specific car call registration that is automatically performed, the guide dog user does not need to operate the car call registration unit 40.

  In addition, when comprised so that it may be determined whether a passenger is a guide dog user based on the passenger image produced | generated by the passenger image generation part 31, it is not a guide dog but the passenger who carries the pet dog. It is thought that it may be judged as a guide dog user.

  Therefore, attention is paid to the fact that the distance between the guide dog and the guide dog user is shorter than the distance between the pet dog and the passenger carrying the dog. That is, since the lead connected to the guide dog is short while the lead connected to the pet dog is long, the distance between the guide dog and the guide dog user is closer.

  Based on such a point of interest, the camera further includes a camera that captures a passenger image that is an image of a passenger passing through the doorway 11, and the guide dog user determination unit 32 includes a passenger image generated by the passenger image generation unit 31, a camera Based on the passenger image (2nd passenger image) image | photographed by (2), it is comprised so that it may be determined whether a passenger is a guide dog user. In addition, about the camera which image | photographs a passenger image, a dedicated camera may be newly provided and the security camera generally provided in a cage | basket | car may be used.

  Specifically, for example, the guide dog user determination unit 32 is photographed by the camera even when the passenger is determined to be a guide dog user based on the passenger image generated by the passenger image generation unit 31. If the distance between the guide dog and the guide dog user is equal to or greater than a preset threshold value, it is determined that the passenger is not the guide dog user.

  By comprising in this way, the guide dog user determination part 32 can determine more accurately whether a passenger is a guide dog user.

  In addition, when there are a plurality of guide dog users using the elevator, it is preferable that specific car call registration suitable for each guide dog user is automatically performed. In other words, not only determines whether a passenger is a guide dog user, but also identifies a guide dog user from among a plurality of guide dog users, and registers a specific car call according to the guide dog user. Is preferably performed automatically.

  Therefore, even when there are a plurality of guide dog users, attention is paid to the fact that the height of the guide dog user and the size of the guide dog are different. That is, since the characteristics of the guide dog user and the guide dog pair are different, the passenger images as shown in FIG. 2B are also different for each pair.

  In consideration of such a point of interest, the image processing apparatus further includes a storage unit that stores a table that associates the passenger image and the specific car call registration, which is defined in advance, and the guide dog user determination unit 32 receives the passenger image from the table in the storage unit. The specific car call registration corresponding to the passenger image generated by the generation unit 31 is further selected. In this case, the car call registration unit 40 performs the specific car call registration selected by the guide dog user determination unit 32.

  With this configuration, when there are multiple guide dog users who use the elevator, specific cage call registration suitable for each guide dog user is automatically performed, improving the convenience of each guide dog user. Can be made.

  Further, when the guide dog user determination unit 32 determines that the passenger is a guide dog user, the specific car call registration may be automatically performed after a certain period of time. That is, when the guide dog user determination unit 32 determines that the passenger is a guide dog user, the specific car call registration is performed if the car call registration unit 40 is not operated by the passenger for a certain period of time. Also good. Note that the measurement start timing for measuring the predetermined time may be set in advance.

  With this configuration, even if the guide dog user determination unit 32 erroneously determines that a passenger who is not a guide dog user is a guide dog user, the car call registration unit 40 is operated within a certain time. Thus, it is possible to prevent specific car call registration from being performed.

  As described above, according to the first embodiment, the first passenger image representing the passenger characteristics is generated based on the multi-beam sensor that detects the light-shielding information of the passenger passing through the entrance of the car and the detection result by the multi-beam sensor. And a guide dog user determination unit that determines whether or not a passenger boarding the car is a guide dog user with a guide dog based on the first passenger image generated by the passenger image generation unit. And a car call registration unit configured to perform predetermined specific car call registration when the guide dog user determination unit determines that the passenger is a guide dog user.

  Thereby, even if a guide dog user does not operate a car call registration part, desired car call registration is performed automatically, and the convenience of a guide dog user can be improved.
