Thereby, the area drawing management unit 24 acquires a value ID, a region ID, and a format ID for the pattern image P1 corresponding to the area A1.
- the area drawing management unit 24 reads the control value corresponding to the area ID acquired in step S204 from the air conditioning information memory 23. For example, when the area ID whose content is “area A1” is acquired in step S204, the area drawing management unit 24 sets the control value “25” located in the first row of the table shown in FIG. Is read. Thereby, the area drawing management unit 24 acquires a control value for the pattern image P1 corresponding to the area A1.
- the area drawing management unit 24 reads the drawing color information corresponding to the format ID acquired in step S204 and defined by the control value acquired in step S205 from the expression format memory 24c. For example, when the content of the area ID acquired in step S204 is “area A1” and the control value acquired in step S205 is “25”, the area drawing management unit 24 displays the table shown in FIG. Thus, the drawing color information whose content is “yellow” is acquired as the drawing color information when the control value is 24 or more and less than 28.

- the area drawing management unit 24 reads the control value corresponding to the area ID acquired in step S303 from the air conditioning information memory 23. As a result, the area drawing management unit 24 acquires a control value for any of the areas A1 to A5.
- step S305 the area drawing management unit 24 determines whether or not the control values for the areas A1 to A5 have been updated. This determination is made by comparing the most recently acquired control value with the latest control value. If the area drawing management unit 24 determines that the control value has not been updated (step S305: No), the area drawing management unit 24 proceeds to step S311. On the other hand, when it is determined that the control value has been updated (step S305: Yes), the process proceeds to step S306.
- step S306 the area drawing management unit 24 reads drawing color information corresponding to the format ID acquired in step S303 and defined by the control value acquired in step S304 from the expression format memory 24c. Thereby, the area drawing management unit 24 acquires drawing color information. For example, when the control value is updated from “25” to “30”, the drawing color information whose content is “orange” is acquired.
- step S307 the area drawing management unit 24 determines whether the content of the drawing color information is “none” or other “yellow”, “orange”, “red”. Judge whether there is. If the content of the drawing color information is any one of “yellow”, “orange”, and “red” (step S307: Yes), the area drawing management unit 24 proceeds to step S309.

- the area drawing management unit 24 For drawing the partial image FRa, for example, the area drawing management unit 24 outputs the address information of the portion overlapping the image pattern of the frame image FR to the graphic engine, and the graphic engine is only in the area defined by the address. This is realized by drawing the frame image FR.
- the color of the pattern image P1 shown in FIG. 3 is updated from “yellow” to “orange” by the above processing.
- step S307 if the content of the drawing color information is “none” in step S307 (step S307: No), the area drawing management unit 24 proceeds to step S308. In this case, in step S310, drawing color information including “background color” is output, and the pattern images P1 to P5 filled with the background color are overwritten.
- step S311 the area drawing management unit 24 determines whether or not the counter value N is greater than or equal to a threshold value.
- the threshold value is equivalent to the number of pattern images P1 to P5 displayed on the display unit 26, and the threshold value is 5 here. If the counter value N is not equal to or greater than the threshold value (step S311: No), the area drawing management unit 24 returns to step S302, and thereafter repeats the processing from step S302 to step S311 until the determination in step S311 is affirmed. Execute. On the other hand, if the counter value N is greater than or equal to the threshold value (step S311: Yes), the area drawing management unit 24 returns to step S301 and initializes the counter value N. Then, the processes of steps S302 to S311 are executed. Thereby, the colors of the pattern images P1 to P5 constituting the image IM shown in FIG. 3 are sequentially updated as the control value is updated.
- the air-conditioning target space of the office building 100 is defined by the rectangular pattern images P1 to P5 having different fill patterns depending on the air-conditioning situation and the frame image FR overlapping the pattern images P1 to P5.
- the image IM shown is constructed. For this reason, when the air conditioning conditions such as the temperature and humidity of each area A1 to A5 as the air conditioning target space change, the rectangular pattern images P1 to P5 are displayed in the display color regardless of the shape of each area A1 to A5. It is only necessary to change and redraw. Therefore, the amount of information to be handled when the image IM is updated according to the change in the air conditioning status is reduced, and the image IM can be updated accurately in a short time.
- the frame image FR shaped into a shape corresponding to each of the areas A1 to A5 is displayed in a state where it overlaps the pattern images P1 to P5. Therefore, the shapes of the areas A1 to A5 indicated to the user by the pattern images P1 to P5 match the shapes of the areas A1 to A5 in the office building 100. Therefore, the layout of the office building 100 can be accurately displayed even when the shapes of the areas A1 to A5 are complicated.
- a general-purpose drawing unit can be used instead of an arithmetic device having a relatively high processing speed, and the cost and size of the device can be reduced.
- the graphic engine 25 has a clipping drawing function 25b.
- the air-conditioning state changes for example, referring to FIG. 12, only the pattern images P1 to P5 to be updated and the partial image FRa of the frame image FR that overlaps the pattern image are redrawn. (Difference drawing process S2).
- difference drawing process S2 the difference drawing process S2 shown in FIG. Good.
- image information is stored in the structural drawing memory 24a, the area definition memory 24b, and the expression format memory 24c constituting the area drawing management unit 24 without being compressed.
- the present invention is not limited to this, and the image information may be stored in a compressed state in each of the memories 24a to 24c.
- run length compression can be considered as a compression format of image information.
- hardware such as the graphic engine 25 can decompress the compression information in order from the base address. Since the frame image FR shows the outer wall of the office building 100 and the like, there are many continuous portions, and the image information can be efficiently compressed.
- each of the pattern images P1 to P5 may have a shape such as a circle, a triangle, or a parallelogram.
- Such polygons can be drawn at high speed using the graphic engine 25.

- the mesh pattern of the pattern images P6 to P7 displayed on the second layer has a lower drawing ratio and becomes a rough pattern than the mesh pattern of the pattern images P1 to P5 displayed on the first layer.
- the graphic engine 25 may start drawing from a pattern image having the highest mesh pattern drawing rate, and finally draw a pattern image having the lowest mesh pattern drawing rate. In this case, pattern images having a coarse mesh pattern are overwritten sequentially. Therefore, the pattern images P1 to P8 can be drawn on the same layer.
