  One of the major features of the elevator system according to this embodiment is that various information provided in the car 160 is collectively displayed on the display device 163, so that various types of information can be obtained without moving the user's eyes. The point is that information can be provided. That is, the display device installed in a conventional elevator car displays the next floor information as character information, but not all information is displayed on this display device. The lighting of the buttons and stop floor display must be confirmed. In this embodiment, the problems of these conventional examples can be solved. In addition, since a large amount of information can be displayed on the display device 163, it is not necessary to provide another display device, so that the cost can be reduced and the structure can be simplified.

  Another major feature of this embodiment is that the display device 163 includes a first display screen 200 having a full screen as a display area, a first display area 301 divided vertically, and a second display area. By making it possible to display the second display screen 300 including the display area 302, it is possible to display necessary information in an easy-to-see manner according to the usage state.

  Specifically, the elevator control device 110 displays a first display screen 200 in a normal display, and the first display screen 200 displays a moving direction display 201 of a car 160, a current position display 202, and a scheduled stop. The floor display 204 and the guidance display 203 are displayed large. When the elevator control device 110 receives a preset input signal from a sensor or the like, the elevator control device 110 changes from the first display screen 200 to the second display screen 300 and displays the first display in the first display area 301. The content of the screen 200 is compressed and displayed, and information 303 corresponding to the input signal is displayed in the second display area 302. FIG. 1 shows a state in which the door opening time of the entrance / exit 161 is graphically displayed.

  Thereby, information with high use frequency can always be displayed, and information necessary only in a specific use state can be displayed according to the situation. In this embodiment, when a release extension button (not shown) provided on the operation panel 162 is operated, an input signal exceeding the weight is received from the weight sensor 121, or an input signal exceeding a specified value is received from the earthquake sensor 124. Then, the first display screen 200 is switched to the second display screen 300, and information 303 related to these input signals is displayed in the second display area 302.

  In this embodiment, the scheduled stop floor display 204 displayed on the first display screen 200 can be omitted.

  Hereinafter, the embodiment of the present invention will be concretely described with reference to the installation diagram of the display device of FIG. 2, the operation flow of FIG. 6, and the display screen examples shown in FIGS. 3 to 5 and FIGS. Explained.

  In FIG. 2, in this embodiment, a rectangular thin display panel having a long side length L1 of 184 mm and a short side length L2 of 139.8 mm is vertically arranged as the display device 163. To do. In this embodiment, the effective display area is 153.7 mm × 115.8 mm, the dot configuration is (640 × RGB) × 480 dots, and the dot pitch is 0.079 × 0.237. A normal white dot matrix color TFT or LCD module is used.

  In this embodiment, (1) the display device 163 is arranged beside the entrance / exit 161, and (2) the display device 163 is a cage so that even a user in a standing posture can see the head over other users. Considering that it is necessary to arrange above 160 and (3) the elevator moves up and down, a thin display panel that is normally used in landscape orientation is installed in portrait orientation.

  Some liquid crystal display panels used as this type of thin display device are designed with different viewing angles depending on the viewing direction of the display panel. In this embodiment, the cost is reduced by adopting display devices having different viewing angles that are generally distributed as the display device 163 of the elevator. The inventors pay attention to the fact that the display device used in the elevator is arranged to be biased to one side of the entrance / exit 161, and one long side of the display devices designed with different viewing angles. Display device with a narrow viewing angle and a large viewing angle on the other long side, and installed so that the viewing angle is narrow on the wall surface side of the car 160 and the viewing angle is large on the opposite entrance / exit 163 side. Devised. For example, in this embodiment, the wall side is set to 50 degrees, the facing entrance and exit are set to 70 degrees, and the upper and lower sides are set to 70 degrees. Thereby, the visibility of the user at the position on the side facing the display device 163 with respect to the entrance / exit 161 can be improved.

  In this embodiment, the display device 163 is installed in a vertically long posture. In general, since the elevator user recognizes that the user's confidence moves in the vertical direction, the information displayed on the display device 163 matches the user's recognition, so that the display is easy to see. Therefore, in this embodiment, paying attention to the fact that the elevator tower 130 is long in the vertical direction, the vertical display device 163 that can display a large amount of information while maintaining the recognition is adopted.

  On the other hand, information corresponding to a preset input signal from a sensor or the like includes character information and the like, and thus a display area that is long in the horizontal direction is good. That is, since recent Japanese text information and English are generally written horizontally, a long space is effective. Therefore, in this embodiment, the display screen of the display device in the vertical position is divided into two parts, and information related to the input signal is displayed in a long space on one side.

  Furthermore, in an elevator, the current position, the planned stoppage floor, and the moving direction are information that the user always needs. Further, in a display device installed at a position looked up by the user, information displayed at the upper position is easier to see than information displayed at the lower position. Therefore, in this embodiment, frequently used information is displayed in the first display area 301 and information displayed as necessary is displayed in the second display area 302.

  Next, screen transition of the first display screen will be described with reference to FIGS. 3, in this embodiment, when the first display screen 200 is displayed, the current position display 202 and the moving direction display 201 are displayed on one side of the vertically long display screen, and the scheduled stop floor display 204 is displayed on the other side. The guidance display 203 is displayed at the lower end of the vertically long display screen. In this embodiment, since the movement direction display 201 is an arrow display, the current position display 202 and the movement direction display 201 are displayed as shown in FIG. The moving direction display 201 is displayed on the top, and if the moving direction is downward, the display position is reversed and displayed as shown in FIG.

  In addition, the guidance display 203 is selected and displayed from the data stored in the storage device 112 by the elevator control device 110 in accordance with the operation state of the elevator. Furthermore, when the planned stop floor display 204 and the input device 164 are operated, the planned stop floors that have been input and registered are sequentially stacked in the vertical direction. This display state will be described with reference to FIG.

  In FIG. 4, this embodiment displays one scheduled stop floor display 204 as a rectangular block. For example, as shown in FIG. 5A, when the user operates the floor operation button “17” with the input device 164, a block in which the numerical value “17” is displayed is displayed on the upper left of the display device. Further, when the 13th and 14th floor operation buttons are operated, these blocks are displayed in a stacked manner. Here, even if the operation of the floor operation button is operated at random, the planned stop floor display 204 is arranged and displayed so that the upper level is higher along the floor of the building.

  However, as shown in FIG. 5B, when a large number of the planned stop floor displays 204 are registered, the blocks cannot be displayed in a stacked manner even in the vertically long display device 163. Therefore, in this embodiment, when the registered scheduled stop floor display 204 exceeds a predetermined number, as shown in (c), the block display is changed to the planned stop floor display 205 which is a normal block display; The stop scheduled floor display 205 is divided into a planned stop floor display 206 having a smaller block size and displayed in a stacked manner.

  For example, in this embodiment, when five or more planned stoppage floors are registered as shown in FIG. 5 (b), it cannot be displayed in the normal block size. Therefore, as shown in FIG. A predetermined number (three in this embodiment) of planned stoppage floors close to the position floor is displayed in the normal block size, and a planned stoppage floor more than the predetermined number is displayed in small blocks.

  Although FIG. 4 has been described with reference to the upward movement display, in the case of the downward movement display, the positions of the scheduled stop floor displays 205 and 206 are displayed so as to be reversed.

  Thus, according to the 1st display screen 200, since the moving direction display 201 and the present position display 202 are displayed largely, the user can grasp | ascertain the content clearly. In addition, if a stop floor is indicated through the operation panel 162 in accordance with a normal form of use of the elevator, the stop floor is displayed in a stacked manner in accordance with the floor order of the building on one side of the current position display 202, so that it is easy to recognize. Furthermore, even if there are a large number of planned stoppages, the planned stoppage floor close to the current position is large, and the distant planned stoppage floor is displayed small, which is easy for the user to recognize. Although the scheduled stop floor display 206 is displayed in a small size and is difficult to see, the planned stop floor is displayed in a normal size when approaching that floor, and is not an obstacle.

  Next, display contents accompanying the movement of the elevator will be described with reference to FIG. When the user registers the stop floor via the operation panel 162, the movement direction display 201, the current position display 202, and the planned stop floor display 204 are centrally displayed on one display screen as shown in FIG. Then, when a predetermined time elapses, the elevator control device 110 displays a message “Door closes” on the guidance display 203 to call attention and control to close the door.

  When the door is closed, the planned stop floor display 204 is switched to the operation state display 207, and “next is the 10th floor” is displayed on the guidance display 203 as the next planned stop floor. The display content of the current position display 202 changes corresponding to the position of the car 160.

  The operation state display 207 is displayed so as to schematically show the floor state of the building by stacking a plurality of rectangular blocks. In this operation state display 207, the floor block 208 corresponding to the current position display 202 is displayed so as to be distinguishable from other floor blocks, and a planned stop floor mark 209 is displayed next to the floor block registered as the planned stop floor. Is displayed. The scheduled stop floor mark 209 is displayed even if the floor apparatus 150 is called.

  Here, in this embodiment, the display contents of the operation state display 207 can be selected in the initial setting of the display formats of FIGS. (B) and (c). (A) The display format shown in the figure is a display method of sequentially switching the blocks of the operation state display 207 that can be stacked and displayed on the first display screen 200. For example, in FIG. 4B, the floor block 208 is “9”, but when the vehicle passes the 10th floor, the block of the operation status display 207 is “11, 12, 13, 14, 15”. Switch. On the other hand, the display method in FIG. 6C is a display method in which the floor block 208 is always displayed at the bottom (upward movement) or the top (downward movement) of the block of the operation state display 207. In addition, as an intermediate display method between FIGS. 5 (b) and (c), when the floor block 208 comes to an intermediate position of the operation state display 207, the block of the operation state display 207 may be shifted by half. . That is, when the operation state display 207 is displayed, the block of the operation state display 207 is switched or displayed at any time including the floor block 208.

  When the elevator control device 110 approaches or stops the registered scheduled stoppage floor and opens the door, as shown in FIG. Display to alert the user and open the door.

  Next, a second display screen when a specific input signal is received will be described using the operation flow diagram of FIG. 6 and the screen examples of FIGS. 7 and 8.

Whether or not (step 401). In this embodiment, an operation signal of an open extension button provided on the operation panel 162, an input signal of excess weight from the weight sensor 121, an input signal exceeding a specified value from the earthquake sensor 124, and an input signal from the fire sensor 123 are second. The corresponding signal of the display screen 300 is set.

  When the elevator control device 110 determines in step 401 that the signal is not the corresponding signal of the second display screen 300, the elevator control device 110 corrects the content displayed on the first display screen 200. On the other hand, when it is determined in step 401 that the corresponding signal is on the second display screen 300, the screen content is switched from the first display screen 200 to the second display screen 300. When switching, it may be switched instantaneously, but in this embodiment, the first display screen 200 is gradually compressed upward and becomes the size of the first display area 301 (step 404). In accordance with the compression operation, the information 303 corresponding to the input signal is read from the storage device 112 and displayed in the second display area 302 that gradually expands (step 405), whereby the display contents are changed to the user. This makes it possible to call attention to the upper portion 303.

  Now, the elevator control device 110 determines whether or not the processing of the input signal has been completed (step 406), and if completed, switches the screen from the second display screen 300 to the first display screen 200 and ends (step 407). ). On the other hand, if the process is not completed in step 406, the process proceeds to step 405. In this embodiment, the steps shown in FIG. 6 are sequentially repeated to display various information on the display device 163.
