The temperature sensor 24 and the humidity sensor 25 may be provided for each air conditioning zone 23a1, 23a2,.

  Next, a series of processes of the air conditioning complaint display device 1 configured as described above will be described with reference to FIG.

  Each air conditioner system 2a, 2b,... Always gives air conditioning control command data to the corresponding air conditioners 21a, 21b,... According to control instructions from the air conditioning controllers 22a, 22b,. .., 23an), (23b1, 23b2),... At this time, the air conditioning control devices 22a, 22b,... Are in the vicinity of the air conditioners 21a, 21b,... Or each air conditioning zone 23a1, ..., 23an, 23b1, every predetermined time (for example, every 10 minutes, every 30 minutes, every hour). The temperature measurement data and the humidity measurement data measured by the temperature sensor 24 and the humidity sensor 25 installed for each of 23 b 2,... Are captured and transmitted to the air conditioning complaint display device 1.

  On the other hand, in the air conditioning complaint display device 1, when the operation starts, the complaint management processing unit 13 executes the initial menu image display means 13A.

  The initial menu image display means 13A reads the initial menu image data from the image data storage area 11A and displays it on the display unit 14 (S1). The displayed initial menu image is a graphic image that enumerates all the air conditioner systems 2a, 2b,... And prompts the user to select one of the air conditioner systems.

  In the initial menu image display means 13A, after the initial menu image is displayed on the display unit 14, the communication control unit mentioned above receives system status data (current date / time, temperature measurement data, humidity) from each air conditioner system 2a, 2b,. It is determined whether measurement data or the like has been received (S2).

  Here, for example, when it is determined that the system status data of the air conditioner system 2a has been received, the sub-processing routine 20 shown in FIG. 6 is internally executed while the initial menu image is displayed. This sub-processing routine 20 determines whether or not there is an interruption (S21). If there is no interruption, the system status is set in the area of the corresponding air conditioner system 2a in the system status data storage area 11C of the complaint occurrence management database 11. Data (date and time of current month, temperature measurement data, humidity measurement data, etc.) are stored in time series (S22). Then, after storing the system status data of the air conditioner system 2a, it is determined whether the system status data has been received from another system, for example, the air conditioner system 2b,... (S23). Returning, it is confirmed whether or not there is an interrupt. If there is no interrupt, the process of storing the system status data in the area of the corresponding air conditioner system 2b in the system status data storage area 11C is repeatedly executed. If no system status data is received in step S23, the process returns to step S1.

  By the way, when an air conditioning complaint is received from a resident in an air conditioning zone of a specific air conditioning system, for example, 2a, to the central monitoring room, the building management room, or the like by telephone, the monitoring staff displays the initial menu displayed on the display unit 14. When an air conditioner system having an air conditioning complaint is clicked from the image, for example, 2a, the complaint management processing unit 13 executes the system management image display means 13B.

  That is, when the system management image display means 13B receives a click signal (touch signal) for selecting an air conditioner system, for example, 2a from the initial menu image, it generates a system selection interrupt signal (S3) and sends it to the sub-processing routine S20. If the system status data is being stored, immediately after stopping, the complaint monitoring function-equipped GUI image 18 shown in FIG. 2 relating to the air conditioner system 2a is read from the image data storage area 11A of the complaint occurrence management database 11, This is displayed on the display unit 14 (S4).

  In the GUI image 18 with the claim monitoring function displayed on the display unit 14, the number of complaints on the day and the number of complaints on the current month are displayed in the display area of the number of complaints on the current day and the number of complaints on the current month respectively. Claim touch buttons 18ba and 18bb are provided in association with the display area of the number of complaints.

  As a result, after accepting an air conditioning complaint that is hot or cold, the monitoring staff immediately clicks on the complaint touch button 18ba or 18bb corresponding to the complaint content, and the complaint management processing unit 13 executes the complaint reflection processing means 13C. .

  For example, when the claim touch button 18ba is clicked, the claim reflection processing means 13C determines that there is an air conditioning complaint that is “hot” (S5), and the date related to the air conditioner system 2a in the system-specific complaint total data storage area 11B. Then, after adding “+1” to the “hot” complaint total counter for the current month (S6), based on the number of complaints of this complaint total counter, the GUI image 18 with the complaint monitoring function shown in FIG. 2 and the detailed GUI image 19 shown in FIG. Is updated (S7).

  Further, the claim reflection processing means 13C, as described above, stores the data such as the air conditioner system that received the air conditioning complaint, the number of complaints of the current day / month counted up by +1, the date / time of occurrence of the complaint, etc. Save to.

  As a result, the number of hot complaints on the day of the GUI image 18 with the complaint monitoring function displayed on the display unit 14 is changed from “3” to “4”, and the number of hot complaints for the current month is changed from “9” to “10”.

  Therefore, when the supervisor receives an air conditioning complaint, the number of complaints for the current day and the current month is calculated and the number of complaints is updated and displayed simply by clicking on the complaint touch buttons 18ba and 18bb corresponding to the contents of the complaint. The number of displayed complaints can be easily confirmed, and the management of the number of air conditioning complaints for each air conditioning system is very easy.

  When the complaint management processing unit 13 executes the reflection process related to the occurrence of the air conditioning complaint and then clicks the detailed touch button 18bc displayed on the GUI image 18 with the complaint monitoring function, the detailed image display means 13D and the complaint number change processing means 13E is executed.

  When the detail touch button 18bc is clicked (S8), the detail image display means 13D reads the claim detail GUI image data of the corresponding air conditioner system, for example, 2a, from the image data storage area 11A, and the claim detail GUI as shown in FIG. The image 19 is displayed on the display unit 14 (S9).

  Therefore, the number of complaints including the contents of the complaint of the current air conditioner system, for example, 2a, can be grasped from the displayed complaint detail GUI image 19, and if the number of complaints on the day is incorrect, the change touch button 19a or 19b is displayed. By touching (S10), the content of the counter for “hot / cold of the relevant system” in the system-specific complaint total data storage area 11B of the complaint occurrence management database 11 is corrected, and accordingly, the GUI image 18 with the claim monitoring function is provided. The number of complaints for the current month / year including the number of complaints on the current day of the complaint details GUI image 19 is changed (S11).

  Thereafter, it is confirmed whether or not the process is a continuation process (S12). If the continuation process is to be performed, the suspension of the sub-process routine is canceled, the process returns to step S1, and the same process is repeated.

  Further, although not shown, the complaint management processing unit 13 is provided with a complaint analysis data recording processing means.

  The complaint analysis data record processing means is configured to store the complaint occurrence management database 11 with respect to the complaint occurrence status management table 12A at the time required for each day (for example, 24:00). The air conditioner system that has received the air conditioning complaint stored in the separate complaint total data storage area 11B and the system status data storage area 11C, the number of complaint occurrences, the date and time of complaint occurrence, the temperature data of the time closest to the complaint occurrence date and time, and Humidity data is read and recorded sequentially in the corresponding item fields.

  Therefore, according to the embodiment as described above, when an air conditioning complaint is received, if an air conditioner system with a complaint is selected from the displayed initial menu image, a GUI image with a complaint monitoring function of the air conditioner system is selected. 18 is displayed, it is possible to easily grasp the current complaint occurrence status of the air conditioner system, and the complaint touch button 18ba or 18bb corresponding to the complaint content in the GUI image 18 with the complaint monitoring function is displayed. Simply click to add 1 to the number of complaints and reflect it at least in the GUI image 18 with the complaint monitoring function. Every time a complaint occurs, you can immediately update the number of complaints for the current day and the current month. The occurrence status can be managed systematically.

  Further, by clicking the detailed touch button 18bc provided on the GUI image 18 with the complaint monitoring function, the complaint detailed GUI image 19 is displayed, and not only the number of complaints on the current day / current month / current year but also the change touch button 19a, By clicking 19b, the number of complaints entered on the day is corrected and reflected in various GUI images, so even if there is an error in the number of complaints, it can be easily changed. Not only can you immediately understand the status of complaints, but you can also manage them appropriately.

  In addition, the air conditioner system that received the air conditioning complaint, the number of complaint occurrences, the date and time of complaint occurrence, the temperature data and the humidity data of the time closest to the complaint occurrence date are recorded in the complaint occurrence status management table 12A for each required time. It can be used for complaint analysis to determine under what weather conditions the air conditioning complaint occurs for each air conditioner system.
