Description

  The present invention relates to an in-car announcement device for a two-way elevator.

  In elevators, there are one way and two way doors, and in the case of two ways, elevator users find it inconvenient because they do not know which door the destination floor will be. There is a case.

  On the other hand, the prior art described in Patent Document 1 is known. In this prior art, based on the imaging information of a camera, the direction of the face of the passenger in the car is detected, and it is determined whether or not the direction of the door to which the next stop floor opens is directed. Then, if the passenger is not pointing in the direction of the opening door, an announcement is generated from the voice guidance. Thus, the passenger can be guided to the opening door of the next stop floor without causing inconvenience to the passengers.

JP 2007-119101 A

  In the above-mentioned prior art, guidance by announcement is performed only to the passenger in the car. However, no consideration is given to the convenience (for example, smooth boarding etc.) of the boarding customer when the boarding customer from the landing on the way floor occurs.

  Therefore, the present invention provides an elevator announcement device that can improve the convenience of both the in-car passenger and the onboard customer from the middle floor by an announcement to the in-car passenger.

  As shown in FIG. 2, the announcement device 201 according to the present embodiment registers a car call registration device 202 for registering operation information (destination floor) of the car button 103 and a hall for registering operation information (hall call) of the hall button 107. A call registration device 203 and a position detection device 204 for acquiring position information of a passenger in the car 102 photographed by the stereo camera 105 are provided. Further, the announcement device 201 detects the arrival on the way floor detecting device 205 which detects whether there is boarding from the landing on the next stop floor based on the information from the car call registration device 202 and the landing call registration device 203, and position detection An announcement determination unit 206 that determines whether or not an announcement into the car is necessary based on information from the device 204 and the mid-floor boarding detection unit 205, and when the announcement determination unit 206 determines that an announcement is necessary An announcement control device 207 for outputting an announcement is provided.

  The processing operation of the elevator car announcement device according to the present embodiment will be described below.

  FIG. 3 is a flowchart showing the overall processing operation of the present embodiment.

  First, the mid-floor boarding detection device 205 detects the presence or absence of boarding on the mid floor (step S301).

  Next, when there is a boarding on the way floor, it is determined based on the information of the stereo camera 105 whether to announce the passenger in the car to move to the door side of the getting-off side (step S302) .

  Next, when the announcement is performed, the announcement in the car is performed (step S303).

  FIG. 4 is a flowchart showing the details of the halfway floor boarding detection process (step S301 in FIG. 3) by the halfway floor boarding detection device 205 (FIG. 2).

  First, the user gets into the car 102 and depresses the call button 103 of the in-car operation panel 101 to detect whether the destination floor is registered in the destination floor registration device 202 (step S401).

  If the destination floor is registered (step S401, Yes), the car 102 leaves for the destination floor. At this time, it is detected whether a landing call is registered in the landing call registration device 203 by pressing the landing button 107 so that another user who is at the landing 106 uses the elevator (step S402).

  If registration of the hall call is detected (S402, Yes), it is determined whether the next stop floor is the same as the hall call floor (step S403).

  If the next stop floor is the same as the landing call floor (S403, Yes), it is determined that there is boarding on the way floor (S404).

  If there is no registration of the destination floor (S401, No), if there is no landing call registration (S402, No) and if the next stop floor is not the landing call floor (S403, No), there is no boarding on the way floor It determines (step S405).

  For example, on the first floor, the user gets into the car 102 and selects the third floor as the destination floor. Thereby, it is detected that the destination floor of the third floor is registered in step S401. At this time, when another user who is on the landing on the second floor selects the upward direction of the landing button 107, it is detected that the landing call on the second floor is registered in step S402. If registration of this landing call is before the car 102 stops at the first floor or passes through the second floor (the landing call floor), the car 102 then stops at the second landing floor (the second floor). Accordingly, since it is determined in step S403 that the next stop floor is the hall call floor (Yes in step S403), it is determined that the intermediate floor is present (S404).

  In addition, since the destination call on the 3rd floor is registered and the elevator travels after registration of the landing call, and the elevator has passed the 2nd floor, the car 102 does not stop on the 2nd floor (the landing call floor), so the next stop The floor is the third floor (destination floor). Therefore, it is not determined that the next stop floor is the landing call floor (step S403, No), and it is determined that the intermediate floor is not boarded (S405). In addition, since the elevator passes 2nd floor also when the hall call of the 2nd floor is downward, it is similarly determined that there is no boarding on the way.

  FIG. 5 is a flowchart showing details of the announcement determination process (step S302 in FIG. 3) by the announcement determination device 206 (FIG. 2).

  First, it is determined whether or not it is determined that there is boarding in the middle floor in the halfway floor boarding detection processing (step S301 in FIG. 3) (step S501).

  If it is determined that the intermediate floor is boarded (Step S501, Yes), the door direction for opening / closing at the next stop floor (half floor) is different from the door direction of the destination floor registered in the car call registration device 202 It determines (step S502).

  If the door direction of the next stop floor (the middle floor) is different from the door direction of the destination floor (Step S502, Yes), next, based on the position information of the passenger obtained from the stereo camera 105 by the position detection device 204, It is determined whether there is an empty space in the car 102 (step S503).

  If it is determined that there is an empty space in the car (step S503, Yes), then, based on the position information of the passenger, the passengers in the car concentrate on the door side that opens and closes at the next stop floor (halfway floor) It is determined whether or not (step S504).

  If it is determined that the passenger is concentrated near the door that opens and closes at the next stop floor (half floor) (S504, Yes), the passenger on the next stop floor (half floor), ie, the passenger waiting to the landing, smoothly goes to the car It is determined that an announcement for guiding a passenger in the car is necessary in order to open the vicinity of the door which opens and closes on the next stop floor in advance so that the passenger can get on (step S505).

  If it is not determined that there is a landing on the way floor (Step S501, No), if it is not determined that there is an empty space in the car (Step S502, No), the door direction of the next stop floor (the middle floor) is When it is not determined that the direction of the door of the destination floor is different (Step S503, No), and when it is not determined that the passenger is concentrated in the vicinity of the door that opens and closes at the next stop floor (intermediate floor) In step S504, No), it is determined that the announcement is unnecessary (step S506).

  Here, a specific example of the processing operation of FIG. 5 will be described. Furthermore, it explains, using Drawing 6 ad. FIG. 6 shows the position of the passenger 603 in the car 102 and the distribution density of the passenger in the car obtained by processing the image of the stereo camera 105 correspondingly.

  For example, when a passenger who got in on the first floor registers the third floor of the destination floor, the upper floor call is registered at the second floor before the car 102 passes the second floor. It stops on the second floor, which is the middle floor (step S501, Yes). When the front door 602 opens and closes on the second floor, which is the next stop floor, and the back door 601 on the third floor, which is the destination floor, opens and closes (step S502, Yes), based on the image information of the stereo camera 105, Detect the location of passengers in the car and the availability of the car.

  If the passengers in the car are densely packed near the front door 602 opening and closing on the second floor (intermediate floor) as shown in FIG. 6A at the first boarding on the first floor, the distribution density of the passengers 603 in the car is It becomes high near the front door 602. That is, there is a vacant space in the car (Step S503, Yes), and the passengers are concentrated on the door side of the next stop floor (Step S504, Yes).

  In this case, it is determined that the announcement is necessary (step S505), and an announcement execution process as described later is executed to guide the passenger 603 in the car toward the back side door 601 that opens and closes at the destination floor, as shown in FIG. As such, the distribution density of passengers in the car is high near the rear door 601. That is, passengers in the car approach the vicinity of the back side door 601 that opens and closes at the destination floor (the third floor), and an empty space is created near the front side door 602 that opens and closes at the middle floor (the second floor). As a result, the passengers in the car can smoothly get off at the arrival of the destination floor, and the waiting customers on the second floor can smoothly get in the car at the arrival of the car. Therefore, after the waiting customer gets in, as shown in FIG. 6c, the original passenger whose destination floor is on the third floor continues to be located near the rear door, and the passenger who gets in from the middle floor is located near the front door .

  In addition, when there is no empty space in the car (Step S503, No), the position and distribution density of the passengers in the car are as shown in FIG. 6d, and it is difficult to move the passengers in the car. The determination is made (step S506), and the announcement implementation process is not executed.

  In the case where a plurality of destination floors are registered in step S502 in FIG. 5, it is determined whether the door direction opened and closed in the next stop floor is different from the door direction of all destination floors, and it is determined that they are different. Alternatively, step S503 may be executed, and step S506 may be executed if the determination is not made. In this case, since the destination floor is different depending on the passengers in the car, the announcement is determined to be unnecessary so that the passengers in the car are not confused by the announcement.

  FIG. 7 is a flowchart showing details of the announcement execution process (step S303 in FIG. 3) by the announcement control device 207 (FIG. 2).

  First, in the announcement determination process (step S302 in FIG. 3), it is determined whether the announcement is determined to be necessary.

  If it is determined that the announcement is necessary (step S701, Yes), voice announcement is performed to urge the passenger in the car to move toward the door that opens and closes on the destination floor. At this time, preferably, identification numbers (1, 2, etc.) or characters (A, B, etc.) are displayed on the front and back side bidirectional doors, and the numbers, characters, etc. are announced. Further, a lighting device such as an LED may be provided near the two-way door or door, and the lighting device on the door side that opens and closes at the same time as the announcement may be lighted or blinked. By these, the passenger in the car can surely grasp the moving direction.

  After the announcement is performed, it is next determined whether the car has arrived at the hall call floor (intermediate floor) (step S703).

  If it is determined that the car has arrived at the hall call floor (the middle floor) (Yes at step S703), the announcement execution process is ended (END). At this time, if the announcement is being performed when the car arrives, the announcement may be interrupted, or the announcement may be continued without interruption so as not to give a sense of discomfort to the passengers in the car. The contents of the announcement are stored in advance in the storage device of the announcement control device 201.

  When it is not determined that the car has arrived at the hall call floor (half floor) (S703, No), the positional information of the passenger in the car is acquired again, and the passenger moves based on the acquired positional information. It is determined whether or not there is (step S704).

  When it is determined that the passenger is moving (S704, Yes), the announcement execution process is ended (END). If it is not determined that the passenger is moving (S704, No), it is determined whether a predetermined time, for example, 5 seconds has elapsed (step S705).

  If it is determined that the predetermined time has elapsed (S705, Yes), the process returns to step S702 again to perform an announcement.

  As described above, when the door to open and close at the destination floor and the door to open and close at the middle floor are different, the necessity of announcement is judged from the vacant situation in the car and the position of the passenger, and the door to open and close at the destination floor By conducting an announcement that guides the passengers to the vicinity, it is possible to prevent the passengers in the car from feeling discomfort or inconvenience, and make it possible to smoothly get on the waiting passengers (boarding passengers) on the way floor. it can.

  In the embodiment described above, the position information of the passenger in the car is detected using a stereo camera, but a monocular camera can be used instead of the stereo camera as described below.

  When using a single-eye camera, a load sensor that detects the load in the car is also used. The load sensor measures the number of passengers in the car.

  As described above, the position detection device 204 (FIG. 3) operates in steps S503 and S504 in FIG. 5 and in step S704 in FIG.

  In step S503, when the value of the load sensor is lower than a predetermined threshold value, it is determined that there is an empty space in the car. Here, the threshold can be arbitrarily set, such as 40% of the rated weight (capacity). For example, if there are three passengers in a nine-seater elevator, the measured value of the load sensor will be about 30% of the rated weight. At this time, since the measured value is less than the threshold (40%), it is determined that there is an empty space in the car, and the process proceeds to step S504 in FIG. In step S504, the position of the passenger is detected from the information of the monocular camera and the load sensor.

  As an example, the case where a monocular camera is installed at the upper side of the center of the car in an elevator having doors on the front and back of the car will be described.

  The position detection device compares the in-car image when the car is unmanned with the in-car image when there are passengers in the car, and detects whether the passengers are not concentrated near the door of the next stop floor. At this time, the information of the load sensor is used. For example, when there are three passengers in a nine-seater elevator and it is in the vicinity of the next stop floor door, the difference in the image by the monocular camera occurs in the entire vicinity of the door. Can be detected, but it is difficult to identify individual passengers from the image and detect the number of people. Here, it is detected from the load detection value by the load sensor that the number of passengers is three. Therefore, it can be determined from the image information acquired by the monocular camera and the information on the number of passengers obtained by the load sensor that the three passengers are near the door. In addition, also in step S704 of FIG. 7, the movement of the passenger in the car can be similarly detected.

  The present invention is not limited to the embodiment described above, and includes various modifications. For example, the embodiments described above are described in detail to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the configurations described. In addition, it is possible to add, delete, and replace another configuration for part of the configuration of each embodiment.

  For example, the announcement is not limited to voice, and a liquid crystal display device or an electronic display device may be used.

  Further, the two-way entrances and exits in the elevator may be located on the front side and the back side, or may be located in two directions at right angles.

  Further, in FIG. 5 described above, the announcement may be executed on the condition that the determination of Yes is made in Step 502, or on the condition that the determination of Yes is made in Step 502 and the determination of Yes in Step S503. An announcement may be performed. In these cases, the announcement is performed regardless of the status of the vacant space in the car and the concentration of passengers in the car. Therefore, the announcement preferably includes information indicating conditions such as when it is possible to move in the car.
