Next, a control unit that controls the display unit 3 will be described.

As shown in FIG. 1, the liquid crystal display 10 (liquid crystal display device) including the display unit 3 includes a display control unit 11, an image control unit 12, and a communication control unit 13 as control units.

The display control unit 11 receives the image display data created by the image control unit 12, controls the display unit 3 according to the received image data, and displays the information provided to the elevator user on the display unit 3 as characters. It is displayed by a picture or a figure.

In normal times, the image control unit 12 creates image data including a number indicating the position (floor) of the car 1 and an arrow indicating the moving direction of the car 1. The position of the car 1 and the moving direction of the car 1 are acquired from the operation control unit 21 that controls the operation of the car 1 in the elevator control device 20. The data of the position and the moving direction of the car 1 possessed by the operation control unit 21 is transmitted by the communication control unit 22 to the communication control unit 13 in the control unit of the liquid crystal display 10. The image control unit 12 creates image display data according to the position and moving direction of the car 1 indicated by the data received by the communication control unit 13, and transmits the image display data to the display control unit 11.

When an earthquake occurs while the elevator is in operation and the elevator control device 20 receives an earthquake detection signal from an earthquake detector (not shown), the elevator control device 20 changes the elevator operation mode from normal operation to earthquake control operation. Switch. At this time, the operation control unit 21 moves the car 1 to the nearest floor and stops it, and also indicates to the liquid crystal display 10 via the communication control unit 22 that the operation mode is switched to the earthquake control operation mode. Send the operation mode switching signal.

When the operation mode switching signal is received by the communication control unit 13, the image control unit 12 creates image data for changing the display screen of the display unit 3 to the display screen 3A in FIG. This image data is displayed on the display screen in the upper first display area 31 with a number indicating the current position of the car 1 and an arrow indicating the moving direction of the car 1, and the lower second display area 32. It consists of a Korean display, a Japanese display, and an English display of earthquake information displayed at the top, center, and bottom, respectively. Here, in the Japanese display in the central portion of the second display area 32, the character size is larger than the Korean display and the English display.

The image control unit 12 creates image display image data for changing the display screen of the display unit 3 to the display screen 3A in FIG. 1, and then, as described later (see FIG. 3), displays the display unit at predetermined time intervals. Image data for changing the display screen of No. 3 to the display screens 3B, 3C, etc. in FIG. 1 are sequentially created.

When the operation mode of the elevator returns from the control operation during an earthquake to the normal operation, the operation control unit 21 transmits a return signal indicating the return to the normal operation to the liquid crystal display 10 via the communication control unit 22. When the return signal is received by the communication control unit 13, the image control unit 12 finishes creating display image data including earthquake information, and indicates normal image data, that is, the position (floor) of the car 1. Create image data in which numbers and arrows indicating the moving direction of the car 1 are arranged vertically on the display screen.

FIG. 2 is a flowchart showing an outline of the processing executed by the control unit and the elevator control device in the liquid crystal display 10 (liquid crystal display device). In addition, it will be described with reference to FIG. 1 as appropriate.

In step S11, the elevator control device 20 determines whether or not an earthquake has occurred based on the presence or absence of an earthquake detection signal from an earthquake detector (not shown). The elevator control device 20 executes step S11 again when no earthquake has occurred (No in step S11), and then executes step S12 when an earthquake has occurred (Yes in step S11).

In step S12, the elevator control device 20 shifts the elevator operation mode from normal operation to seismic control operation.

At this time, the elevator control device 20 moves the car 1 to the nearest floor and stops it by the operation control unit 21, and also transmits an operation mode switching signal to the liquid crystal display 10. When the control unit of the liquid crystal display 10 receives the operation mode switching signal, the image control unit 12 creates seismic control display data (see step S13), that is, image data including seismic information as described above. Send.

When step S12 is executed by the elevator control device 20, the control unit of the liquid crystal display 10 next executes step S13.

In step S13, the display control unit 11 in the control unit of the liquid crystal display 10 determines whether or not the seismic control display data (image data) created by the image control unit 12 is received. When the display control unit 11 has received the seismic control display data (Yes in step S13), the display control unit 11 then executes step S14. Further, when the display control unit 11 has not received the seismic control display data (No in step S13), the display control unit 11 then executes step S16.

In step S14, the display control unit 11 displays the position and moving direction of the car and the seismic information on the display unit 3 according to the received seismic control display data (see the display screen 3A in FIG. 1). As will be described later, the seismic control display data is switched each time step S14 is executed in a predetermined cycle. That is, the combination of multiple languages for displaying earthquake information is switched. Further, among a plurality of languages, the language to be emphasized is switched (in this embodiment, Japanese, English, Chinese, and Korean are switched in this order (display screens 3A, 3B, 3C in FIG. 1 and a diagram described later). See 3)).

When the display control unit 11 executes step S14, the display control unit 11 then executes step S15.

In step S15, the display control unit 11 determines whether or not the time count value of the display switching timer exceeds a predetermined time, 2 seconds in this embodiment, and if it does not exceed 2 seconds (No in step S15). , Step S15 is executed again, and if it exceeds 2 seconds (Yes in step S15), step S13 is executed again. This predetermined time, that is, 2 seconds, is a switching cycle of the display screen of the display unit 3 by the display control unit 11.

When the display control unit 11 determines in step S15 that the time count value of the display switching timer exceeds a predetermined time, the control unit of the liquid crystal display 10 displays a new seismic control display by the image control unit 12. Data (see display screen 3B in FIG. 1) is created and transmitted. Therefore, when step S13 and subsequent steps are executed again by the display control unit 11, the display screen of the display unit 3 is switched according to the new seismic control display data (for example, the display screen from the display screen 3A shown in FIG. 1). Switch to 3B).

Switching of the display screen including such earthquake information is executed until the operation mode of the elevator returns from the control operation during an earthquake to the normal operation. As described above, when the control unit of the liquid crystal display 10 receives the return signal indicating the return to normal operation from the elevator control device 20, the image control unit 12 ends the creation of the display image data including the earthquake information. Then, create image display data in normal times. Therefore, the display control unit 11 determines in step S13 that the seismic control display data has not been received, and then executes step S16.

In step S16, the display control unit 11 indicates the position (floor) of the car 1 on the display unit 3 without displaying the earthquake information according to the normal image data received from the image control unit 12. , And an arrow indicating the moving direction of the car 1 is displayed.

FIG. 3 schematically shows the switching of the display screen in the present embodiment.

A, B, C and D in the figure indicate Japanese display, English display, Chinese display and Korean display of earthquake information, respectively. The character sizes of A, B, C, and D in the figure correspond to the character sizes in each display. The display screens 3a, 3b, and 3c correspond to the display screens 3A, 3B, and 3C in FIG. 1, respectively.

As shown in FIG. 3, the display screens 3a, 3b, 3c, and 3d including the first display area 31 and the second display area 32 are switched in this order at predetermined time intervals (for example, “2 seconds” as described above). Be done.

The earthquake information is displayed in four languages, and the display in three languages is displayed in the second display area 32. Seismic information is displayed in different languages in the upper, central, and lower three stages of the second display area 32. When the display screen is switched, each display moves up one step. Therefore, the display in the language displayed at the upper part before the switching ends, and the display in the language that was not displayed before the switching among the four languages starts at the lower part. That is, in each of the upper part, the central part, and the lower part, the languages are periodically switched in the order of A, B, C, D, starting from different languages (A, B, C, D).

Further, as shown in FIG. 3, on each display screen, the language characters located in the central portion of the second display area 32 are larger and highlighted than the language characters located in the upper and lower parts. ..

Next, a modified example of the means for emphasizing the characters in the language for displaying the earthquake information displayed at a predetermined position on the screen will be described.

FIG. 4 shows a modified example of the means for emphasizing characters.

Similar to the above-described embodiment, the display unit 3 has a first display area 31 for displaying the position and moving direction of the car, and a second display area 32 for displaying earthquake information in a plurality of languages.

The rectangle drawn by the broken line shown in the second display area 32 indicates one character being displayed in one language among the plurality of languages. The size of the rectangle indicates the size of the characters.

As shown in FIG. 4, the display of earthquake information is scrolled from the bottom to the top in the second display area 32. During scrolling, as shown by the rectangles a1, a2, a3, and a4 in FIG. 4, the size of the character gradually increases as it moves from the lower part of the second display area 32 toward the central part, and the central part. Is the maximum (a4). Further, as shown by the rectangles a4, a5, a6, and a7 in FIG. 4, the size of the characters gradually decreases as the character moves upward from the central portion of the second display area 32. In this way, the size of the characters changes, and the size of the characters is maximized at a predetermined position, that is, the central portion of the second display area, so that the display of the seismic information located in the central portion is emphasized.

In the case of the modification of FIG. 4, when the image control unit 12 (FIG. 1) receives the operation mode switching signal (switching from normal operation to seismic control operation mode) from the elevator control device 20 (FIG. 1), the image control unit 12 (FIG. 1) shifts to normal operation. Until the return signal of is received, scroll moving image data including the display of seismic information according to this modification is created and transmitted to the display control unit 11 (FIG. 1).

In the modified examples of FIGS. 4 and 5, scrolling may be stopped for a certain period of time when emphasizing characters.

FIG. 5 shows another variation of the means for emphasizing characters.

Similar to the above-described embodiment, the display unit 3 has a first display area 31 in which the position and moving direction of the car are displayed, and a second display area 32 in which seismic information is displayed in a plurality of languages.

The rectangle drawn by the broken line shown in the second display area 32 indicates one character being displayed in one of a plurality of languages. The size of the rectangle indicates the size of the characters.

As shown in FIG. 5, the display of earthquake information is scrolled from the bottom to the top in the second display area 32. During scrolling, as the rectangles b1, b2, b3, and b4 in FIG. 4 show, the size of the characters is constant.

In this modification, in the central portion (b3) of the second display area 32, the attributes of characters other than the size of the characters, for example, the color and the font, are made different from the attributes of the characters located in other parts. This emphasizes the display of seismic information located in the center.

The emphasizing means in the modified examples of FIGS. 4 and 5 may be applied to characters in a plurality of languages simultaneously displayed on the display screen in the first embodiment.

In the case of the modified example of FIG. 5, the image control unit 12 (FIG. 1) creates scroll moving image data and transmits it to the display control unit 11 (FIG. 1) in the same manner as the modified example of FIG.

According to the above-described embodiment and its modification, the information provided to the elevator user is displayed in a plurality of languages on the display screen, and the characters in the language displayed at a predetermined position on the display screen are the characters in other languages. By emphasizing the above, the elevator user can surely recognize the information. Further, by emphasizing and displaying the characters, even if the characters of a plurality of languages are mixed on the screen, the elevator user can easily recognize his / her own language.

Further, when the display of information in each language displayed on the screen moves on the screen in time and moves to a predetermined position on the display screen, the display is emphasized. Therefore, the highlighted language is displayed on the screen even before or after the highlighting. Therefore, the time for the elevator user to recognize the information is secured. This prevents information from being overlooked.

In addition, by emphasizing the characters in the center of the display area, it becomes easier for the elevator user to pay attention. This prevents information from being overlooked.

In addition, even if the number of languages displayed on the screen is smaller than the number of languages used to display information, by moving the display on the screen, all the languages used to display information are displayed on the screen. Timing is secured. Further, it is possible to display in a large number of languages without increasing the screen size of the display unit (liquid crystal display in the embodiment) of the display device.

The present invention is not limited to the above-described embodiment, and includes various modifications. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the described configurations. Further, it is possible to add / delete / replace a part of the configuration of each embodiment with another configuration.

For example, the position where the characters are emphasized on the display screen is not limited to the central portion and may be arbitrary.

The number of languages used for displaying information is not limited to four languages, but may be any plurality of languages. In addition, the number of languages displayed on the display screen may be any plurality of languages. Further, one language may be displayed in a plurality of forms. For example, in the Japanese display, a display including Chinese characters and a display containing only hiragana may be used together.

Further, the information provided to the elevator users is not limited to earthquake information, but may be information on disasters, accidents, power outages, breakdowns, crime prevention, and the like. In this case, not only the signal from the elevator control device 20, but also the control unit of the display device may start and end the process of displaying these information in response to the signals from various building management devices.
