The general manager selects one special monitoring group registered in the group database 35f in the selection field, inputs special monitoring conditions to be applied to the special monitoring group in the input field, and in this state, the confirm button When is pressed, the condition setting unit 32g stores the input special monitoring condition in the storage unit 35. The special monitoring condition is associated with the name of the special monitoring group selected via the selection field.
It is assumed that the monitoring condition setting window can be easily changed from the group registration window.

(7) Setting of exclusion conditions As described above, the indoor units 10a, 10b,... Belonging to the special monitoring group are special due to special monitoring conditions (including time intervals P3 and P6 and items I3 and I6). Collection of driving information and judgment of whether there is an abnormality. For the special monitoring group, it is possible to set an exclusion condition for excluding the indoor units 10a, 10b,... From the special monitoring group as necessary. The exclusion condition can be set as a condition that denies the special monitoring condition corresponding to the special monitoring group, or can be set as a condition independent of the special monitoring condition.
Hereinafter, a procedure in which the general manager sets an exclusion condition for the special monitoring group will be described.
First, the general manager operates the input unit 34 of the parent controller 30 to display an exclusion condition setting window on the display unit 33. The exclusion condition setting window is a GUI for setting an exclusion condition for excluding the indoor units 10a, 10b,...

The general manager selects one special monitoring group registered in the group database 35f in the selection field, inputs an exclusion condition to be applied to the special monitoring group in the input field, and presses the confirm button in this state. Then, the condition setting unit 32g stores the input exclusion condition in the storage unit 35. The exclusion condition is associated with the name of the special monitoring group selected via the selection field.
It is assumed that the exclusion condition setting window can be easily shifted from the group registration window and the monitoring condition setting window.

(8) Specific Contents of Extraction Conditions, Special Monitoring Conditions, and Exclusion Conditions The general manager can set the extraction conditions, special monitoring conditions, and any exclusion conditions, for example, in combination as follows: .
(8-1)
As a normal monitoring condition related to the detection of a certain abnormality, it is set that a state in which a predetermined state value (temperature, pressure, etc.) of a predetermined component included in the air conditioner 10 is equal to or higher than a predetermined value S1 continues for a predetermined time T1. In this case, it is set as an extraction condition that the abnormality has occurred a predetermined number of times or more within a predetermined time. As a special monitoring condition related to the detection of the abnormality, it is set that the state where the state value of the part is equal to or greater than the predetermined value S2 continues for a predetermined time T2. Note that S1> S2 and / or T1> T2. Alternatively, or in addition to this, as a special monitoring condition related to the detection of the abnormality, another state value (temperature, pressure, etc.) that can predict the occurrence of the abnormality is the same. Or a condition based on the same or different state value of another component. As the exclusion condition, it is set that the treatment for the abnormality is performed. The success or failure of the exclusion condition can be determined by referring to the abnormality history database 35d.
According to the above combination, it is possible to prevent the recurrence of an abnormality or to detect a slight modulation at an early stage before an abnormality occurs.

(8-2)
The extraction condition is set to satisfy the exclusion condition (8-1). Alternatively, or in addition to this, when the manufacturing number of a part included in the air conditioning equipment 10 is changed, or when the parent controller 30 is connected to the remote management server of the service center, the server The information indicating that the treatment has been completed is set in the service history database. The change of the production number can be determined by referring to the basic information database 35e, and the parent controller 30 determines whether or not the service history database contains information indicating that the treatment has been completed. This can be determined by accessing or receiving notification from the remote management server. As a special monitoring condition, a stricter condition relating to detection of an existing abnormality is set. Alternatively, instead of or in addition to this, as a special monitoring condition, a logic different from an existing condition for determining an abnormality may be set. As the exclusion condition, it is set that no abnormality is detected under the special monitoring condition within a predetermined time after entering the special monitoring group.
According to the above combination, it can be confirmed that the treatment for the abnormality has been appropriately performed.

(8-3)
As an extraction condition, set that the model has been confirmed to be defective. Extraction of indoor units 10a, 10b,... Of the same model is performed when the general manager inputs a model name or model number as a search key and searches the basic information database 35e. As a special monitoring condition, a logic for monitoring a sign of a failure of a product of the model is newly added, and / or an existing abnormality detection condition is changed to be stricter. As the exclusion condition, it is set that a measure for the defect has been taken.
According to the above combination, when a problem is confirmed in a specific model, it is possible to ensure safety until a measure is taken by the manufacturer.

(8-4)
As an extraction condition, set that it was newly added as a monitoring target. The success or failure of the extraction condition is determined, for example, by whether or not the initial setting related to the connection to the parent controller 30 has been performed. As special monitoring conditions, generally, logic for detecting abnormalities that are likely to occur as construction failures and initial failures and / or logic for estimating the ability of newly added equipment are set, and / or existing Change the conditions for detecting anomalies to be more stringent. As the exclusion condition, it is set that no abnormality is detected under the special monitoring condition and / or the predetermined ability is maintained within a predetermined time after entering the special monitoring group.
According to the above-described combination, it is possible to detect an abnormality related to a construction failure or an initial failure that is likely to occur at the time of updating or adding a device at an early stage.

(8-5)
As an extraction condition, the temperature difference between the set temperature of the indoor units 10a, 10b,... And the room temperature (for example, the suction temperature detected by the temperature sensor near the air suction port of the indoor unit) is a predetermined value or more. It is set that T4 has continued for a predetermined time. As a special monitoring condition, it is set that the state where the temperature difference is equal to or greater than the predetermined value has continued for a predetermined time T5, or that the number of times corresponding to the extraction condition has occurred a predetermined number of times within a predetermined time. Note that T5 >> T4. As an exclusion condition, a condition that negates the special monitoring condition is set.
According to the above combination, it is possible to find a lack of capacity of the air conditioning equipment 10 or a malfunction in the operation state (such as an inappropriate setting temperature or a door or window being left open).

(8-6)
As an extraction condition, it is set that it has been in the activated state for a predetermined time or more after the time of the last stop control of the day according to the operation schedule. It is assumed that the operation schedule is held in the parent controller 30 or the child controllers 20a, 20b,. As a special monitoring condition, it is set that the extraction condition falls within a predetermined number of times U1 within a predetermined time. As the exclusion condition, it is set that the extraction condition only corresponds to the predetermined number of times U2 or less within the predetermined period. Note that U2 <U1.
According to the above combination, it is possible to find forgetting to turn off the time zone that should have stopped, such as at night.
The above-mentioned “to make conditions for detecting existing anomalies more strict” means the contents as exemplified below.
Example 1) When the existing condition is “temperature of a certain part> first temperature”, the severe condition is “temperature of a certain part> second temperature”. However, the second temperature <the first temperature, and the second temperature belongs to the normal temperature range.
Example 2) When the existing condition is “temperature of a certain part <third temperature”, the severe condition is “temperature of a certain part <fourth temperature”. However, the fourth temperature> the third temperature, and the fourth temperature belongs to the normal temperature range.

Note that the same applies to the case of making a determination as in Examples 1 and 2 regarding pressure rather than temperature.
Example 3) When the existing condition is “a state continues for the first time”, the severe condition is “a state continues for the second time or more”. However, the second time <the first time, and the second time is longer than the normal operating range.
Example 4) When the existing condition is “the establishment of a certain state is the first occurrence”, the severe condition is “the establishment of a certain state is the second occurrence”. However, the second number is smaller than the first number, which is larger than the number that can occur in the normal operation range.

(9) Management Screen The management screens shown in FIGS. 7 to 11 are screens used for managing the indoor units 10a, 10b,... By the general manager, and are created by the display control unit 32d of the parent controller 30, It is displayed on the display unit 33 of the controller 30.
The management screen is mainly divided into three areas A1 to A3. The tree structure Ts, To is displayed in the left area A1, a schematic diagram of the entire facility 1 or the space constituting the facility 1 is displayed in the area A2 that extends greatly in the center, and the right area A3 includes Various operation buttons B1 to B5 are displayed.
a) Tree Structure As shown in FIGS. 7 to 11, the space tree structure Ts in the left region A1 is a tree-like arrangement of a plurality of objects composed of square icons and characters arranged on the left and right. More specifically, the space tree structure Ts has an object O1 corresponding to the entire facility 1 as a root object, an object O2 corresponding to a building 1a, 1b,... Branches from the object O1, and further from each object O2. The object O3 corresponding to the unit space is branched. The object O2 corresponds to the buildings 1a, 1b,... On a one-to-one basis, and the object O3 branched from each object O2 is a unit space in the buildings 1a, 1b,. One-to-one. The display control unit 32d refers to the sketch map database 35a and arranges the objects O1 to O3 according to the data structure, thereby forming the space tree structure Ts.

The characters included in each of the objects O1 to O3 are determined based on the index information in the sketch map database 35a. That is, the character included in the object O1 corresponding to the entire facility 1 is determined as “facility 1” based on the index information added to the sketch of the entire facility 1, and the character included in the object O2 corresponding to the building 1a. Is determined as “building 1a” based on the index information added to the floor plan of the building 1a, and the characters included in the object O3 corresponding to the unit space occupying the fourth floor north side in the building 1a are the characters in the building 1a. Based on the index information added to the sketch of the unit space occupying the fourth floor north side, it is determined to be “the fourth floor north side”.
The icons included in the objects O1 to O3 indicate the states of the indoor units 10a, 10b,... In the space (the entire facility 1, buildings 1a, 1b,..., Or unit space) corresponding to the objects O1 to O3. The color changes according to the. In addition, the state of each indoor unit 10a, 10b, ... is determined by the condition determination part 32c. The display control unit 32d determines the color to be assigned to each icon according to the determination result, and changes the color of the icon.

More specifically, the condition determination unit 32c refers to various databases in the storage unit 35 at the time interval P7 (in this embodiment, every minute), and each indoor unit 10a, 10b,. It is determined whether or not the search conditions C1, C2,. On the other hand, the display control unit 32d changes the color of the icon corresponding to each space (the entire facility 1, the building 1a, 1b,... Or unit space) at the time interval P8 (in this embodiment, every minute). I will decide. When the at least one indoor unit 10a, 10b,... In the space corresponding to the icon satisfies the search condition C1, the color of the icon does not satisfy the first color and the search condition C1, but the search condition C2. If the condition is satisfied, the second color is determined. In other words, different colors are associated with the search conditions C1, C2,... In advance, and the color assigned to the icon is a color corresponding to the matching search conditions C1, C2,. However, when a plurality of search conditions C1, C2,... Match, the search conditions C1, C2,. If none of the search conditions C1, C2,... Is satisfied, the default color is used.

As described above, the general manager simply looks at the icon of the space tree structure Ts, and the facts (more accurately, such as abnormalities occurring in the indoor units 10a, 10b,... In the space corresponding to the icon). , Whether or not at least one of the indoor units 10a, 10b,... In the space corresponding to the icon matches the search conditions C1, C2,. The search conditions C1, C2,... In the storage unit 35 can be changed, added, and deleted at any timing by the general manager operating the input unit 24. That is, the general manager can freely set the search conditions C1, C2,... So that the fact that he / she wants to monitor is reflected in the color of the icon.
The search condition C1 is a condition that is satisfied when an abnormality has occurred. Therefore, the general manager can check the abnormality in the indoor units 10a, 10b,... From the color of the icon. Note that whether or not a certain indoor unit 10a, 10b,... Matches the search condition C1 is determined by referring to the abnormality history database 35d by the condition determination unit 32c.

As other search conditions C2,..., The following are set, for example.
As a first example, a condition that the set temperature is 25 ° C. or lower and the room temperature is 25 ° C. or lower is also mentioned. In such a case, the presence of overcooled indoor units 10a, 10b,... In which the set temperature is set to a low value of 25.degree. C. or lower and the actual indoor temperature is 25.degree. C. or lower from the color of the icon. Can be checked. Note that whether or not a certain indoor unit 10a, 10b,... Matches the search condition is determined by referring to the driving information database 35c by the condition determination unit 32c.
Moreover, as a 2nd example, what is set as conditions on the date of manufacture being five years ago or before and driving | running | working is mentioned. In such a case, it is possible to check whether the old indoor units 10a, 10b,. It should be noted that whether or not a certain indoor unit 10a, 10b,... Matches the search condition is determined by referring to the basic information database 35e and the operation information database 35c by the condition determination unit 32c.

As shown in FIGS. 7 to 11, the option tree structure To is displayed below the space tree structure Ts in the left area A1 by the number of special monitoring groups registered in the group database 35f. The That is, the option tree structure To corresponds one-to-one with the special monitoring group registered in the group database 35f, and is not displayed when the special monitoring group is not registered in the group database 35f.
The option tree structure To is a tree-like arrangement of a plurality of objects consisting of square icons and characters arranged on the left and right. More specifically, in the option tree structure To, an object O7 corresponding to one special monitoring group is a root object, and one pair is assigned from the object O7 to all indoor units 10a, 10b,. 1, the corresponding object O8 is branched.

The characters included in the objects O7 and O8 are determined based on the records in the group database 35f. More specifically, the character included in the object O7 is the name of the special monitoring group corresponding to the object O7, and the character included in the object O8 is the indoor unit 10a belonging to the special monitoring group corresponding to the object O7. The device ID is 10b.
Further, the icon included in each object O8 changes its color according to the state of the indoor units 10a, 10b,... Corresponding to the object O8. On the other hand, the color of the icon included in each object O7 changes according to the state of the indoor units 10a, 10b,... Belonging to the special monitoring group corresponding to the object O7. The determination of the color of the icon on the option tree structure To is performed similarly to the case where the display control unit 32d determines the color to be assigned to the icon on the space tree structure Ts.

That is, the display control unit 32d determines the color of the icons included in the objects O7 and O8 at the time interval P8 according to the determination result by the condition determination unit 32c. When the indoor units 10a, 10b,... Corresponding to the icon satisfy the search condition C1, the color of the icon included in the object O8 does not satisfy the first color and the search condition C1, but satisfies the search condition C2. In this case, it is determined by a method such as the second color, and if none of the search conditions C1, C2,. On the other hand, the color of the icon included in the object O7 is the first color when the at least one indoor unit 10a, 10b,... Belonging to the special monitoring group corresponding to the icon satisfies the search condition C1. If the condition C1 is not satisfied but the search condition C2 is satisfied, the second color is determined. If none of the search conditions C1, C2,. .

The display control unit 32d displays the tree structure to be displayed in the left region A1 at the time interval P10 (for example, every second) while the management screens shown in FIGS. 7 to 11 are displayed on the display unit 33. The mode of Ts and To is determined. Therefore, as soon as the definition information of the spatial structure in the sketch map database 35a is updated, the aspect of the spatial tree structure Ts displayed in the area A1 is changed. Similarly, when the definition information of the special monitoring group in the group database 35f is updated, the mode of the option tree structure To displayed in the area A1 is changed immediately. Accordingly, when a special monitoring group is newly registered, the option tree structure To corresponding to the group is automatically displayed in the area A1, and when it is deleted, it disappears automatically. Further, when there is a change in the indoor units 10a, 10b,... Belonging to the special monitoring group, the number of icons O8 of the option tree structure To corresponding to the group is changed.

As described above, the general manager simply looks at the icon of the option tree structure To, and the facts such as abnormality occurring in the indoor units 10a, 10b,... Corresponding to the icon (more precisely, the icon Whether the indoor units 10a, 10b,... Corresponding to the search conditions C1, C2,... Match, or at least one of the special monitoring groups corresponding to the icon Facts such as abnormalities occurring in the indoor units 10a, 10b,... (More precisely, at least one indoor unit 10a, 10b,. C1, C2,... Can be quickly sensed.
In addition, a folding button is provided on the left side of each of the objects O1, O2, and O7 in layers other than the lowest layer. When the folding button is in the “+” state, it means that the object on the right side thereof (that is, the next lower object) is in a non-display state, and when the folding button is in the “−” state, This means that the object on the right side (that is, the next lower object) is being displayed.

b) Schematic diagram of the entire facility 1 and each space constituting the facility 1 As shown in FIGS. 7 to 9, the central region A2 includes a space currently selected by the general manager via the input unit 34 ( A schematic diagram of the entire facility 1, buildings 1a, 1b,...
