  An air conditioning management system according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a conceptual diagram of an air conditioning management system according to an embodiment of the present invention, and FIG. 2 is a control block diagram thereof.

  As shown in FIGS. 1 and 2, an air conditioning management system 1 according to an embodiment of the present invention includes a controller 2, and a plurality of air conditioners 3 are connected to the controller 2 via communication means 2e. Further, a plurality of client PCs 5 are connected to the controller 2 via the communication means 2 f, the intranet, and the hub 4. In FIG. 2, the hub is omitted.

  The controller 2 includes request determination means 2a, data processing means 2b, display data creation means 2c, database (storage means) 2d, and communication means 2e and 2f. The request determination unit 2a, the data processing unit 2b, the display data creation unit 2c, and the database (storage unit) 2d are the control programs stored in the ROM while the CPU provided in the controller 2 exchanges data with the ROM and RAM. It is realized by executing.

  The air conditioner (indoor unit) 3 is provided with an air conditioner controller 3a for controlling the operation of the air conditioner. The air conditioner controller 3a is connected to the controller 2 via the air conditioner communication means 3b and the communication means 2e. Connected to.

  In such a system configuration, the client PC 5 sends an operation instruction request (operation / stop, set temperature, operation mode, etc.) or various display requests of each air conditioner 3 to the controller 2.

  When there is an operation instruction request from the client PC 5, the controller 2 determines the content of the request determination means 2a, and sends the requested operation signal to the designated air conditioner 3 via the communication means 2e. Send.

  On the other hand, when there is a display request from the client PC 5, the requested display contents are instructed to the data processing means 2b, and the data processing means 2b operates the operation data of each air conditioner 3 from the database 2d according to the requested display contents. Are collected and statistical processing is performed to create base data for display to the client PC 5.

  The display data creation means 2c is requested via the communication means 2f, the intranet, and the hub 4 by converting the base data received from the data processing means 2b into a display language that can be read by a client PC 5 such as HTML using a browser. A reply is sent to the client PC 5.

  On the other hand, the operation data of each air conditioner 3 is collected by communicating each air conditioner 3 and the controller 2 at predetermined time intervals, and using the information (various operation data) of each air conditioner 3 received by the controller 2. It is executed by saving in the database 2d.

  FIG. 3 is a table for easy understanding of data stored in the database 2d. For each air conditioner (address), from the left side of the table, (1) the group (floor to which the air conditioner belongs) ), (2) Operation / stopped state, (3) Operation mode of air conditioner such as cooling / heating, (4) Set temperature, (5) Availability of hand operation specifying whether or not operation by remote control is possible, (6) The room temperature and (7) each condition of the filter sign indicating whether or not the time required to clean the air conditioner filter has arrived are stored for each item.

In the air conditioning management system 1, the air conditioners 3 are grouped into groups 1F for the air conditioners 3a ₁ ,..., 3a ₆ (address aaa 1 to 9) installed on the _first floor. The installed air conditioners 3b ₁ ,..., 3b ₆ (addresses aaa 10 to 15) are classified and managed in units of groups 2F and thereafter to the fifth floor. Then, the operation data for each air conditioner (address) shown in FIG. 3 is called on the controller 2 or the client PC 5 connected to the controller having the Web server function, and will be described in detail later for each group. Each data is processed based on a predetermined rule to collect the operation data, and the operation data for each group is displayed.

  As a result, it is possible to easily check the operating state of the plurality of air conditioners, and it is also possible to easily check the temperature setting, the abnormal value of the room temperature, and the like.

  When the air conditioner is stopped, there is no data because the operation mode is not set. Similarly, there is no set temperature data during stoppage. These are indicated by "-" meaning no data on FIG.

  FIG. 4 shows an example in which the operation data of all the air conditioners 3 is displayed on the monitor screen 5a for each group by using the browser of the client PC 5 from the HTML file sent from the controller 2.

  On the monitor screen 5a, from the left side of FIG. 4, (1) floor 6a, (2) operation / stop 6b, (3) operation number ratio 6c, (4) set temperature 6d, (5) hand operation 6e, (6) The room temperature 6f and (7) the filter sign 6g are displayed in columns in units of floors (groups) for each item. That is, items 6b to 6g, which are operation data of the air conditioner on the same floor, are displayed in the row direction.

  In the present embodiment, since the air conditioner 3 installed on each floor is a group unit, the floor 6a displays the group name as a floor. The operation / stop 6b is “operation” if even one unit is operating in the group, “alarm” if any unit is abnormal in the group, “stop” if all are stopped in the group. Is displayed.

  The hand operation 6e indicates whether or not the air conditioner 3 can be operated by the remote controller provided in each air conditioner 3. The hand operation 6e indicates that the air conditioner 3 in the group (floor) can be operated remotely. "When the remote control operation of each air conditioner 3 in the group (floor) is set to be disabled, the hand operation" prohibited "is displayed. Note that permission / prohibition of hand operation is set uniformly for all the air conditioners 3 in the group, and cannot be set for each individual air conditioner 3 in the same group. The filter sign 6g displays the presence or absence of clogging of the filter provided at the suction port of each air conditioner 3. If the filter clogging occurs in all the units in the group, the black circle or even one in the group is a filter. When clogging occurs, a gray circle is displayed, and when there is no filter clogging for all units in the group, a blank is displayed.

  In the item of the operating unit ratio (%) 6c, the operating unit ratio (operating mode distribution) for each operating mode of each air conditioner 3 in the group is displayed in a bar graph as a percentage. In this bar display, the operation mode of the air conditioner of the entire group can be easily confirmed by color-coding for each operation mode.

  Specifically, based on the operation mode of each air conditioner 3, which is cooling, heating, dry (dehumidification) operation and stop, the cooling operation is blue, the heating operation is orange, and the dry operation is performed. The green state and the stop state are displayed in gray (not shown), and the total of each state is 100%. For example, when the floor 6a is 1F, the ratio of the air conditioner during the cooling operation is 40%, the heating operation is 10%, the dry operation is 10%, and the remaining 40% is stopped.

  Thereby, it becomes possible to easily check the operation mode of the air conditioner in each floor (group), and since each floor (group) from 1F to 5F is displayed in order from the top, The status of the floor operation mode and the difference between floors can be confirmed at a glance.

  In the set temperature 6d, the set temperature range of the air conditioner is displayed for each group for each cooling and heating operation mode. On the floor 1F, 25-26 on the left side of the display indicates the set temperature of the air conditioner in the cooling mode. The range is indicated by the minimum temperature and the maximum temperature, and 18-30 on the right side indicates the set temperature range of the air conditioner during the heating mode. That is, the highest set temperature is 26 ° C. and the lowest set temperature is 25 ° C. of the air conditioner belonging to the floor 1F and in the air conditioner during the cooling operation. In this case, the air conditioners in the same floor (group) are operating at substantially the same set temperature, indicating a normal situation. However, in the air conditioner during heating operation, the highest set temperature is 30 ° C. and the lowest set temperature is 18 ° C., and the difference is too large for the air conditioners belonging to the same group. It is expected that there will be some problem.

  In particular, in the room temperature column described later, the room temperature of each air conditioner on the floor 1F is 25 to 27 ° C., and the set temperature 18 ° C. of the heating operation is much lower than the room temperature. Heating operation is not performed in an air conditioner in which temperature is set. Obviously, it is assumed that the set temperature is too low or the operation mode is selected incorrectly.

  As described above, it is possible to easily confirm the operation data of a plurality of air conditioners for each group, and it is possible to quickly confirm an erroneous setting in the air conditioners in the group. When all the air conditioners in the group are stopped or in the dry operation like the floor 4F, there is no set temperature data, so the display in this column is “**”, indicating that there is no data. It is.

  Moreover, you may make it display the preset temperature 6d according to the operation mode of the air conditioner in the group displayed in FIG. 4 with a color.

  For example, when the set temperature of the air conditioner in the group is 18 ° C., 25 ° C., 27 ° C., 24 ° C., 25 ° C., 25 ° C., and 29 ° C., 18 to 27 ° C./24 to 29 ° C. In this case, the character color may be changed according to the operation mode, and the cooling 18-27 ° C. may be displayed in blue and the heating 24-29 ° C. may be displayed in orange.

  Thereby, the temperature setting status of the air conditioners 3 of the entire group can be confirmed at a glance, and it is possible to easily determine whether the set temperature is too low or too high. In this embodiment, since the dehumidifying operation does not have a set temperature, the set temperature is not displayed for the air conditioner operating in the dehumidifying operation mode.

  In addition, the temperature displayed when the temperature is out of the specified temperature range is set to a color different from the normal color. For example, when the cooling set temperature is lower than the energy saving target temperature of 28 ° C., the set temperature display that is normally displayed in blue is used, and when there is an air conditioner that operates at the set temperature of 29 ° C., the maximum temperature of 29 ° C. is set. It is displayed in red so that the abnormal value can be easily determined, and the operation management of the air conditioner can be performed.

  The indoor temperature 6f displays the indoor air temperature range detected by each air conditioner 3 in the group. For example, from the left, the minimum temperature is 24 ° C, the average temperature is (25 ° C), and the maximum temperature is 27 ° C. indicate. The average temperature is displayed in (). As a result, the indoor temperature distribution for each group can be confirmed, and useless operation of the air conditioner can be suppressed.

  In addition, in the display of the filter sign 6g, the floor 1F is displayed with a black circle, and the all air conditioners in the group are clogged with the filter. Therefore, it is necessary to quickly clean the filters of the all air conditioners in the group. is there. On the floors 2F and 4F, gray circles are displayed, indicating that filter clogging has occurred in at least one of the groups. Therefore, if the user designates and clicks on this display part with a mouse etc., the screen shifts to an individual display screen that displays various operation data of the air conditioner causing the filter clogging, which causes clogging. It is possible to identify air conditioners within a group, and it is possible to quickly cope with filter cleaning. As can be seen from FIG. 3, it is the air conditioner at address aaa12 that causes the filter clogging on the floor 2F, and the air conditioner at address aaa21 that causes the filter clogging on the floor 4F.

  To shift to the individual display screen, an individual display request signal is transmitted from the client PC 5 shown in FIG. 2 to the controller 2 by clicking on the screen of the user, and the request determination unit 2a of the controller 2 determines the request content. Then, the individual operation data of the designated air conditioner is requested to the data processing means 2b, the operation data of the designated air conditioner is read from the database 2d, and the display data preparation means 2c receives the data from the HTML. Is read by the browser, converted into a display language that can be displayed, and sent back to the client PC 5 that requested it. As described above, since various operation data of the air conditioners 3 on all floors are displayed for each group and all groups are displayed in a list, the difference in operation data between the air conditioners in the group and others It becomes easy to judge an abnormality and an erroneous operation from the difference in the operation data with the group.

  According to the air conditioning management system of this embodiment, display for each group reflecting the operating state of each air conditioner, enabling the operating state of a large number of air conditioners to be quickly and accurately confirmed for each group, An air conditioning management system that can easily manage a large number of air conditioners is realized.

  In this embodiment, the example in which the operation data of the air conditioner for each group is displayed on the client PC (display) connected to the controller having the Web server function has been described. However, for each group on the display provided in the controller. The operation data of the air conditioner may be displayed.
