Next, as the processing of the arrangement location management processing section 62, the operator designates the arrangement location of the symbol on the layout diagram (604). Then, the symbol arrangement location on the layout diagram is stored (606). The coordinates of three points for a rectangle and the coordinates of all the corners for a polygon are stored in the symbol arrangement coordinate file 92.

Next, data of the symbol attribute is input from the symbol arrangement section 6 (607). For example, symbol attribute data such as a device name, a product name, a maker, a price, a specification, a purchase time, and a management period corresponding to each symbol are input,
It is held in the symbol attribute file 94. The symbol attribute data is used for search and management by the search processing unit 9.

Further, the display size calculation processing section 64 calculates the display size of the symbols on the layout (60).
8). For this purpose, first, a ratio R between the number of pixels N0 per set actual size on the layout diagram and the number Nd of pixels per set actual size at the time of symbol creation is determined.

R = N0 / Nd (4) Next, the number of pixels Nl to be displayed on the layout drawing is obtained from the number of pixels on each side of the symbol by the following equation (5): Nl = R × Np ( 5) Finally, the combination display processing unit 65 combines and displays the symbol at a predetermined position on the layout diagram of the display screen (61).
0). FIG. 10B shows an example of the composite display.

If it is desired to copy or move the symbol alone or together with the attribute data, copy / move is selected (612). If the position to be copied or moved is on the same layout diagram (614), the process returns to step 606 to set the copy / move position of the symbol.
If a symbol is to be copied on another layout diagram, one of the other layout diagrams is selected by the processing of the layout diagram selection processing section 31 (616). Then, after the selected layout diagram is displayed on the screen (616),
Returning to step 606, the copying / moving position of the symbol is set. Regarding the copied / moved symbol, the data of the symbol attribute already input in the arrangement unit 6 may be used as it is, or a change such as addition or deletion may be made.

Next, the processing flow of the symbol search processing will be described with reference to FIG. In this symbol search process, a specific symbol is searched for from data held in the layout diagram file 90, the symbol attribute file 94, and the like, and the attribute is used for device management and the like.

First, search conditions are set (901).
For example, search conditions such as a product name of a specific maker and a management period of the device are set. According to the search condition, the position of the symbol, that is, which position of which layout diagram is located, is searched (902), and further, the attribute of the symbol is searched (903). These search results are output to a display screen, a printer, or the like, and used for device management.

By this search process, for example, among a large number of devices installed on each floor of a building, those requiring maintenance can be easily extracted. Therefore,
When there are many objects to be managed, such as a layout drawing of each floor of the building, and equipment and devices for each floor, the operation is extremely simple.
