ABSTRACT:
TECHNICAL FIELD
The present invention relates to a method of displaying air-conditioning management information for displaying information on management of a plurality of air conditioners, and an air-conditioning management apparatus for managing a plurality of air conditioners on a centralized basis.
BACKGROUND ART
As a conventional example of a general management apparatus, one disclosed in Japanese Patent Application Laid-Open No. 523/1979 (Method of Controlling Display of Monitoring Apparatus) is known. Hereafter, a description will be given of this conventional example.
As shown in
FIG. 20
, the conventional management apparatus is an apparatus in which a partial image
101
is extracted from an overall image
100
showing the state of a process in an electric power system, and this partial image
101
is displayed on a CRT. This conventional management apparatus is provided with a track ball, and as an operator manipulates the track ball, the screen displayed on the CRT can be scrolled, as shown in FIG.
21
.
With such a conventional management apparatus, it is necessary to repeatedly execute the scrolling operation a number of times until the targeted partial image
101
is displayed by scrolling the screen displayed on the CRT, so that the operational efficiency has been poor and presented a problem. In addition, it is difficult for the operator to judge whether the partial image
101
being displayed on the CRT is displaying an end of the overall image
100
or is displaying the center of the overall image
100
, so that the ease of use has been poor and constituted a problem.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a method of displaying air-conditioning management information and an air-conditioning management apparatus which are capable of overcoming the above-described problems, make it possible to scroll the screen to a targeted partial image with a fewer number of operations, and excel in the operational efficiency. Another object of the present invention is to provide a method of displaying air-conditioning management information and an air-conditioning management apparatus which are readily capable of judging which position of the overall image the partial image being displayed on the CRT is displaying, and which are capable of preventing a malfunction and excel in reliability.
DISCLOSURE OF THE INVENTION
A method of displaying air-conditioning management information in accordance with the present invention is characterized by comprising the steps of: displaying an image in which a partial image is extracted from a layout image of a floor having a plurality of rooms, and the partial image with operating-state data on an air conditioner added thereto is displayed on a display; and shifting an extracting position in which a position of the partial image to be extracted from the layout image is shifted in units of rooms.
In the addition, an air-conditioning management apparatus in accordance with the present invention for managing a plurality of air conditioners on a centralized basis by displaying on a display data on operating states of the air conditioners disposed in each room on a floor is characterized by comprising: image storage means in which a layout image of the floor is stored; image display means for extracting a partial image from the layout image stored in the image storage means, and for displaying on the display the partial image with the operating-state data added thereto; and extracting-position shifting means for shifting in units of rooms a position of the partial image to be extracted from the layout image.
Here, the air-conditioning management apparatus preferably further comprises: partition-line-data storage means in which partition-line data for partitioning the floor into the rooms is stored, wherein the extracting-position shifting means shifts in units of rooms the position of the partial image to be extracted from the layout image on the basis of the partition-line data read from the partition-line-data storage means.
In addition, the partial image is preferably an image including the entire desired room and portions of rooms adjacent to that room.
Further, the air-conditioning management apparatus preferably further comprises: shift switches each adapted to specify a shifting direction at a time when the position of the partial image to be extracted is shifted by the extracting-position shifting means, wherein the shift switches nullifies inputs with respect to unshiftable directions.
Still further, the shift switches are preferably arrow buttons for various directions displayed on a touch panel, and only the arrow buttons in shiftable directions are displayed.
Furthermore, preferably, the layout images concerning a plurality of floors are stored in the image storage means, and the image display means displays on the display the partial image concerning the floor designated among the floors.
