First, the operating temperature of the air conditioner 1 is lowered by x1 ° C. The cooling capacity and operating temperature of the other air conditioners 2 to 5 are fixed (step S1).
After a predetermined time has elapsed, the temperature of the temperature sensor 11 decreases by y1 ° C. This value is recorded (step S2).
When the temperature of the temperature sensor 11 is measured, the operating temperature of the air conditioner 1 is restored (step S3).

After a predetermined time, the operating temperature of the air conditioner 2 is lowered by x2 ° C. (step S4).
After a predetermined time elapses, the temperature of the temperature sensor decreases by y2 ° C. This value is recorded (step S5).

According to the flow, the degree of influence of each air conditioner 1 to 5 on the position of the temperature sensor 11 can be quantitatively measured. Further, if the temperature sensor 11 is moved and the influence degree is sequentially measured, an influence degree map can be created.

  As a result, when it is desired to adjust the temperature at a certain position, it can be understood how much the temperature setting of which air conditioner should be changed.

  In general, an information processing apparatus sensitive to the operating temperature often includes a temperature sensor. In such a case, it is also possible to examine the degree of influence of each air conditioner 1 to 5 on a certain device (information processing device).

  FIG. 3 is a configuration diagram showing another configuration of the air conditioner monitoring system of the present invention.

  3 differs from FIG. 1 only in that the temperature measurement target is changed from the temperature sensor 11 to the information processing apparatus a.

  And the sensor temperature change information collection process part (sensor temperature change information collection means) 113 in the processing program part 110 of the monitoring / control apparatus 100 is an information processing apparatus a for each of the air conditioners 1 to 5 whose set temperature has been changed. Processing to collect the change information of the internal temperature of.

  The influence degree calculation processing unit (influence degree calculation means) 114 obtains the degree of influence of each of the air conditioners 1 to 5 on the information processing apparatus a based on the temperature change information collected by the sensor temperature change information collection processing part 113. Process.

  The influence degree screen display processing unit (influence degree screen display means) 115 displays information on the degree of influence between each of the air conditioners 1 to 5 and the information processing apparatus a obtained by the influence degree calculation processing unit 114 in a tabular format. Alternatively, a process for displaying the screen in a graphic format is performed.

In the database 120, information on the operating state of each of the air conditioners 1 to 5 and information on the internal temperature of the information processing apparatus a are recorded as the device state monitoring information 121. Moreover, the temperature change information 122 records the change information of the internal temperature of the information processing apparatus a corresponding to the change of the set temperature of the air conditioners 1 to 5. The influence degree table 123 is a table in which information on the relationship between the influence degrees of the air conditioners 1 to 5 and the information processing apparatus a obtained by the influence degree calculation processing unit 114 is recorded.

Next, with reference to FIG. 4, a procedure for searching for the degree of influence (relevance) between a certain device (information processing device a) and each of the air conditioners 1 to 5 will be described.
First, the operating temperature of the air conditioner 1 is lowered by x1 ° C. Further, the cooling capacity and operating temperature of the other air conditioners 2 to 5 are fixed (step S11).
After a predetermined time has elapsed, the internal temperature of the information processing apparatus a (the temperature measured by the built-in temperature sensor) decreases by y1 ° C. This value is recorded (step S12).
The operating temperature of the air conditioner 1 is restored (step S13).

After a predetermined time, the operating temperature of the air conditioner 2 is lowered by x2 ° C. (step S14).
After a predetermined time elapses, the temperature of the information processing apparatus a decreases by y2 ° C. This value is recorded (step S15).
The operating temperature of the air conditioner 2 is restored (step S16).

After a predetermined time, the operating temperature of the air conditioner 3 is lowered by x3 ° C. (step S17).
The above procedure is performed for the number of air conditioners (step S18).

  And the influence degree to the position of the information processing apparatus a of the air conditioners 1-5 is grasped | ascertained by the ratio of y1 / x1, y2 / x2, ... (step S19).

  Thereby, based on the relevance of each air conditioner, it can be understood how much air conditioner should be controlled and how much it is desired to lower the temperature of a specific device.

  With the above procedure, the weighting coefficient is set for each device according to the importance, and the sum of the products of the influence and the weighting coefficient is calculated, whereby the importance of the air conditioner can be determined. FIG. 5 shows an example in which the relevance coefficient between the air conditioner and the device and the importance of the air conditioner are displayed on the display unit 116 (liquid crystal display, etc.) of the monitoring / control device 100, and a table (table format). It is an example displayed by.

  In the example shown in FIG. 5, “the relevance between the air conditioner 1 and the device 3 is 0.30”. “If the temperature of the air conditioner 1 is lowered by 1 ° C., the temperature at the position of the device 3 is lowered by 0.30 ° C. Is predicted. In addition, “importance of the air conditioner 1 = 0.66 × 3 + 0.64 × 2 + 0.30 × 1 +.
