FIG. 5 is a flowchart showing a procedure for detecting that foreign matter remains in the sill when the landing door 14 and the car door 18 are about to close in the elevator system 10. First, the control unit 26 acquires data captured by the threshold camera 24 (S10). This step is executed by the function of the photographing data acquisition unit 266 of the control unit 26.

  Next, the data of the sill part in which the data acquired by the imaging data acquisition unit 266 is recorded in advance (data having no foreign substance in the sill part) are compared to determine whether or not the foreign substance exists in the sill part (S12). . Specifically, when the data acquired by the photographing data acquisition unit 266 is compared with the data of the sill part in which the data is recorded in advance (data having no foreign matter on the sill part), the landing door 14 and the car door 18 are about to close. On the other hand, when the two data are different, it is determined that the foreign matter remains, and when the two data match, it is determined that no foreign matter remains.

This step is executed by the function of the opening / closing control processing unit 264 of the control unit 26.

  Subsequently, after S14, the remote center is notified that foreign matter remains in the threshold (S16). This step is executed by the function of the notification processing unit 269 of the control unit 26. Thereafter, the process proceeds to return processing. Thus, according to the elevator system 10, when the landing door 14 and the car door 18 are about to be closed based on the data taken by the threshold camera 24, it is determined whether or not any foreign matter remains in the threshold. This can be judged more suitably.

  Further, according to the elevator system 10, since the sill camera 24 is attached to the door shoe 18 a provided at the lower part of the car 18, even if foreign matter enters the car side sill groove 19. A foreign object can be suitably detected. And according to the elevator system 10, since it has the camera 24 for a sill which image | photographs the periphery of a sill part with a wide angle, since a blind spot decreases, it can detect a foreign material more suitably.

  Furthermore, according to the elevator system 10, when it is determined that the object remains in the sill when the landing door 14 and the car door 18 are closed, the landing door 14 and the car door 18 are opened. It can be in a state where the car 16 is not operated. Therefore, the elevator system 10 can be operated more safely. Further, according to the elevator system 10, when the landing door 14 and the car door 18 are closed, it is notified to the monitoring center when it is determined that the object remains in the sill part. The staff can respond quickly.

  Next, the elevator system 101 which is 2nd embodiment which concerns on this invention is demonstrated. FIG. 6 is a diagram showing an elevator system 101 according to the second embodiment of the present invention. FIG. 7 is a view corresponding to a cross-sectional view taken along line BB in FIG. The elevator system 101 has substantially the same configuration as the elevator system 10, and in addition to the configuration of the elevator system 10, it further differs in that it has a landing camera 20 and the function of the control unit 27 is different. The difference will be mainly described.

  The landing camera 20 has a function of photographing the state of the landing 11 and a function of detecting a movement of an object or the like with the latest image analysis technology. The landing camera 20 divides an image obtained by shooting an object existing on the landing 11 into 4800 frames, and analyzes the objects reflected in each frame so that the shape of the object (the shape of the object, the pattern of the object, the color of the object, Or a combination of these can be recorded as data. The landing camera 20 is attached to, for example, a ceiling portion of the landing 11 and photographs a passenger 2 who waits for the arrival of the car 16 at the landing 11.

  The control unit 27 includes a car lifting / lowering control processing unit, an opening / closing control processing unit, an imaging data acquisition unit, a determination processing unit, and a notification processing unit. Here, the car lifting control processing unit, the opening / closing control processing unit, and the notification processing unit of the control unit 27 have the same functions as the car lifting control processing unit 262, the opening / closing control processing unit 264, and the notification processing unit 269 of the control unit 26, respectively. Therefore, detailed description is omitted.

  The imaging data acquisition unit of the control unit 27 has a function of acquiring two data, data captured by the threshold camera 24 and data captured by the landing camera 20.

  The determination processing unit of the control unit 27 compares the two data acquired by the imaging data acquisition unit of the control unit 27 (the data captured by the landing camera 20 and the data captured by the threshold camera 24). When the landing door 14 and the car door 18 are about to be closed, it is determined that there is a foreign object when the two data match, and the landing door 14, It has a function of giving an opening control command for the car door 18 and giving a notification command for causing the notification processing unit of the control unit 27 to notify the monitoring center.

  The operation of the elevator system 101 configured as described above will be described with reference to FIGS. FIG. 8 is a flowchart illustrating a procedure for detecting that foreign matter remains in the sill when the landing door 14 and the car door 18 are about to close in the elevator system 101. First, the control unit 27 acquires data captured by the threshold camera 24 (S20). This step is executed by the function of the photographing data acquisition unit of the control unit 27.

  Next, data taken by the landing camera 20 is acquired (S22). This step is executed by the function of the photographing data acquisition unit of the control unit 27.

  Then, the two data acquired by the imaging data acquisition unit of the control unit 27 are compared to determine whether or not there is a foreign object in the sill unit (S24). Specifically, the two data acquired by the imaging data acquisition unit of the control unit 27 are compared, and when the landing door 14 and the car door 18 are about to close, foreign matter remains if the two data match. If both data do not match, it is determined that no foreign matter remains. This step is executed by the function of the determination processing unit of the control unit 27. In S24, when the landing door 14 and the car door 18 are about to be closed, if the two data acquired by the photographing data acquisition unit of the control unit 27 do not match, it is determined that there is no foreign object in the sill unit and S20 again. Return to.

  In S24, when the landing door 14 and the car door 18 are about to close, when both data acquired by the imaging data acquisition unit of the control unit 27 match, it is determined that there is a foreign object remaining in the sill unit, The opening control of the landing door 14 and the car door 18 is performed (S26). This step is executed by the function of the opening / closing control processing unit of the control unit 27.

  Subsequently, after S26, the remote center is notified that foreign objects remain in the threshold (S28). This step is executed by the function of the notification processing unit of the control unit 27. Thereafter, the process proceeds to return processing. As described above, according to the elevator system 101, when the landing door 14 and the car door 18 are about to close based on the data taken by the threshold camera 24 and the landing camera 20, foreign matter remains in the threshold. It can be judged more suitably whether it is. For example, when a passenger 2 with a pet 4 connected by a string 3 uses the elevator system 101, only the passenger 2 gets into the car 16 while the pet 4 remains on the landing 11, and the string 3 straddles the sill. There is an advantage that the string 3 can be detected as a foreign object when the landing door 14 and the car door 18 are about to close in a state of being left.

  In the elevator system 101, the landing camera 20 and the sill camera 24 have been described as being separate cameras. However, the sill camera 24 has a function so that the sill portion can be photographed and the hall 11 can also be photographed. Then, there is an advantage that an elevator system can be constructed at a lower cost.

FIG. 10 is a view corresponding to the cross-sectional view taken along the line CC in FIG. Since the elevator system 102 has substantially the same configuration as the elevator system 10, the elevator system 102 is different from the configuration of the elevator system 10 in that it further includes a car camera 22 and the function of the control unit 28. The difference will be mainly described.

  The car camera 22 has a function of photographing the state in the car 16 and a function of detecting the movement of an object or the like with the latest image analysis technology. The car camera 22 divides an image of an object existing in the car 16 into 4800 frames, and analyzes the object reflected in each frame to obtain the object shape (object shape, object pattern, object object). Color, or a combination thereof) can be recorded as data. The car camera 22 is attached to, for example, a ceiling portion of the car 16 and photographs the passenger 2 and the like in the car 16.

  The control unit 28 includes a car lifting / lowering control processing unit, an opening / closing control processing unit, an imaging data acquisition unit, a determination processing unit, and a notification processing unit. Here, the car lifting control processing unit, the opening / closing control processing unit, and the notification processing unit of the control unit 28 have the same functions as the car lifting control processing unit 262, the opening / closing control processing unit 264, and the notification processing unit 269 of the control unit 26, respectively. Therefore, detailed description is omitted.

  The imaging data acquisition unit of the control unit 28 has a function of acquiring two data, that is, data captured by the threshold camera 24 and data captured by the car camera 22.

  The determination processing unit of the control unit 28 compares the two data (the acquired image data taken by the car camera 22 and the two data taken by the threshold camera 24) by the shooting data acquisition unit of the control unit 28, and the hall When the door 14 and the car door 18 are about to be closed, it is determined that there is a foreign object if the two data match, and the landing door 14 and the car are sent to the opening / closing control processing unit of the control unit 28. A function of giving an opening control command for the door 18 and giving a notification command for causing the notification processing unit of the control unit 28 to notify the monitoring center is provided.

  The operation of the elevator system 102 configured as described above will be described with reference to FIGS. FIG. 9 is a flowchart illustrating a procedure for detecting that foreign matter remains in the sill when the landing door 14 and the car door 18 are about to close in the elevator system 102. First, the control unit 28 acquires data captured by the threshold camera 24 (S30). This step is executed by the function of the photographing data acquisition unit of the control unit 28.

  Next, data photographed by the car camera 22 is acquired (S32). This step is executed by the function of the photographing data acquisition unit of the control unit 28.

  Then, the two data acquired by the imaging data acquisition unit of the control unit 28 are compared to determine whether or not a foreign object exists in the sill unit (S34). Specifically, the two data acquired by the imaging data acquisition unit of the control unit 28 are compared, and when the landing door 14 and the car door 18 are about to close, foreign matter remains if the two data match. If both data do not match, it is determined that no foreign matter remains. This step is executed by the function of the determination processing unit of the control unit 28. In S34, when the landing door 14 and the car door 18 are about to be closed, if the two data acquired by the photographing data acquisition unit of the control unit 28 do not match, it is determined that there is no foreign object in the sill part, and again S30. Return to.

  In S34, when the landing door 14 and the car door 18 are about to close, when both data acquired by the imaging data acquisition unit of the control unit 28 match, it is determined that there is a foreign object remaining in the sill unit, The opening control of the landing door 14 and the car door 18 is performed (S36). This step is executed by the function of the opening / closing control processing unit of the control unit 28.

  Subsequently, after S36, a notification is made to the remote monitoring center that foreign matter remains in the threshold (S38). This step is executed by the function of the notification processing unit of the control unit 28. Thereafter, the process proceeds to return processing. As described above, according to the elevator system 102, when the landing door 14 and the car door 18 are about to close based on the data captured by the threshold camera 24 and the car camera 22, a foreign object is generated in the threshold part. It can be more suitably determined whether or not it remains. For example, when the passenger 2 with the pet 4 connected by the string 3 uses the elevator system 101, only the passenger 2 gets down from the car 16 to the landing 11 while the pet 4 remains in the car 16, and the string 3. However, there is an advantage that the string 3 can be detected as a foreign object when the landing door 14 and the car door 18 are about to close in a state of being straddling the sill groove.

  In the elevator system 102, the car camera 22 and the sill camera 24 have been described as being separate cameras, but the sill camera 24 can shoot the sill portion and also shoot the inside of the car 16. The combined use of functions has the advantage that an elevator system can be constructed at a lower cost.

  In the first embodiment to the third embodiment, a mode having only the threshold camera 24, a mode having the threshold camera 24 and the landing camera 20, and a mode having the threshold camera 24 and the car camera 22, respectively. However, it may be configured to detect the foreign matter in the sill portion using three cameras, the sill camera 24, the landing camera 20, and the car camera 22.

  2 passengers, 3 strings, 4 pets, 7 hoistways, 8 main ropes, 10, 101, 102 elevator system, 11 landings, 12 landing walls, 13, 17 openings, 14 landing doors, 15 landing sill grooves, 16 passenger cars , 18 car door, 18a door shoe, 19 car side sill groove, 20 landing camera, 22 car camera, 24 sill camera, 26, 27, 28 control unit, 262 lift control processing unit, 264 opening / closing control processing unit 266, photographing data acquisition unit, 268 determination processing unit, 269 notification processing unit.
