Abstract

An elevator information display device including: an information display control section that selects, based on an elevator state, information to be displayed from elevator information and general information, interrupts, when a predetermined display interruption factor occurs during display of general information, display of the general information concerned, and displays the elevator information; a display state administration section that determines whether or not the general information has finished being displayed to the end of the information display unit; and a redisplay determination section that determines, when the display of general information has been interrupted, based on the display interruption factor relating to the interruption and the result of the determination, whether or not the redisplay of the interrupted general information is necessary, wherein the information display control section redisplays the general information, which has been determined to be necessary to be redisplayed, from the beginning of the information display unit.

Claims

1. An elevator information display device which displays elevator information and general information, which is divided into information display units, in an information display section, comprising:

an information display control section which selects, based on the state of an elevator, information to be displayed in the information display section from the elevator information and the general information, interrupts, when a predetermined display interruption factor occurs during the display of the general information, the display of the general information concerned, and displays the elevator information in the information display section;

a display state administration section which determines whether or not the general information having been displayed in the information display section has finished being displayed to the end of the information display unit; and

a redisplay determination section which determines, when the display of the general information has been interrupted, based on the display interruption factor relating to the interruption and the result of the determination made by the display state administration section, whether or not the redisplay of the interrupted general information is necessary, wherein

the information display control section redisplays the general information, which has been determined to be necessary to be redisplayed by the redisplay determination section, in the information display section from the beginning of the information display unit.

2. The elevator information display device according to claim 1, wherein, in the case where the general information is displayed for predetermined first redisplay determination time or longer from the beginning of the information display unit before the display of the general information is interrupted, the redisplay determination section determines that the redisplay of the general information concerned is unnecessary.

3. The elevator information display device according to claim 2, wherein the predetermined first redisplay determination time is set as a ratio to the information display unit for each of the information display units of the general information.

4. The elevator information display device according to claim 1, wherein, in the case where the general information is not displayed for predetermined second redisplay determination time or longer after the display of the general information has been interrupted, the redisplay determination section determines that the redisplay of the general information concerned is unnecessary.

5. The elevator information display device according to claim 2, wherein, in the case where the general information is not displayed for predetermined second redisplay determination time or longer after the display of the general information has been interrupted, the redisplay determination section determines that the redisplay of the general information concerned is unnecessary.

6. The elevator information display device according to claim 3, wherein, in the case where the general information is not displayed for predetermined second redisplay determination time or longer after the display of the general information has been interrupted, the redisplay determination section determines that the redisplay of the general information concerned is unnecessary.

7. The elevator information display device according to claim 1, wherein, in the case where the display interruption factor is control operation of elevator, the redisplay determination section determines that the redisplay of the general information is unnecessary.

8. The elevator information display device according to claim 2, wherein, in the case where the display interruption factor is control operation of elevator, the redisplay determination section determines that the redisplay of the general information is unnecessary.

9. The elevator information display device according to claim 3, wherein, in the case where the display interruption factor is control operation of elevator, the redisplay determination section determines that the redisplay of the general information is unnecessary.

10. The elevator information display device according to claim 1, wherein, in the case where the display interruption factor is elevator door opening/closing, and no user is present in a car, the redisplay determination section determines that the redisplay of the general information is unnecessary.

11. The elevator information display device according to claim 2, wherein, in the case where the display interruption factor is elevator door opening/closing, and no user is present in a car, the redisplay determination section determines that the redisplay of the general information is unnecessary.

12. The elevator information display device according to claim 3, wherein, in the case where the display interruption factor is elevator door opening/closing, and no user is present in a car, the redisplay determination section determines that the redisplay of the general information is unnecessary.
