DETAILED DESCRIPTION

[0022] <Configuration of an Air Conditioner Management System According to One Embodiment>

[0023] refer to Figure 1 The configuration of an air conditioner management system according to an embodiment of the present invention is described. The air conditioner management system 1 according to the present embodiment includes an air conditioner 10 and a portable terminal 20 capable of performing short-range wireless communication with the air conditioner 10 by means of NFC (Near Field Communication). The portable terminal 20 is a terminal carried by an operator who performs installation work or maintenance inspection of the air conditioner 10.

[0024] The schematic structure of the air conditioner 10 is shown in FIG. Figure 1 The detailed structure is shown in Figure 2The air conditioner 10 includes an outdoor unit 11, an indoor unit 12 connected to the outdoor unit 11 through a communication line and a refrigerant pipeline, and a remote controller 13 communicatively connected to the indoor unit 12. The outdoor unit 11 includes an NFC tag 111 and an outdoor controller 112. The NFC tag 111 includes an outdoor unit antenna 111a for NFC communication, a non-volatile memory 111b, and an information input / output unit 111c. The information input / output unit 111c performs input / output processing of information by means of NFC communication. Any of the outdoor unit 11, the indoor unit 12, or the remote controller 13 can be connected to a higher-level centralized control device of the air conditioner or connected to an air conditioner management server via the Internet.

[0025] The outdoor controller 112 includes a first communication unit 112a, a second communication unit 112b, an outdoor storage unit 112c, and a control unit 112d. The first communication unit 112a communicates with the NFC tag 111. The second communication unit 112b communicates with the indoor unit 12. The outdoor storage unit 112c stores various information related to the outdoor unit 11. The outdoor storage unit 112c uses a non-volatile memory that does not disappear even if the power is cut off, similar to the non-volatile memory 111b of the NFC tag 111. The control unit 112d controls the transmission and reception of information between the NFC tag 111, the indoor unit 12, and the outdoor storage unit 112c.

[0026] The indoor unit 12 has an indoor controller 121 that controls the devices in the indoor unit 12 based on the information sent from the outdoor unit 11 and the information sent from the remote controller 13. The remote controller 13 sends the user's operation information to the indoor unit 12. In addition, the indoor controller 121 sends information for controlling the devices in the outdoor unit 11 to the outdoor controller 112. In addition, the indoor controller 121 sends information to be displayed on the display unit (not shown) of the remote controller 13.

[0027] The portable terminal 20 is constituted by, for example, a smart device such as Figure 3 As shown, it has a terminal antenna 21 for communicating with the NFC tag 111 of the outdoor unit 11 via NFC, a GPS receiving unit 22, an operation information input unit 23, a network communication unit 24, a terminal storage unit 25, a display unit 26 and a terminal control unit 27.

[0028] The GPS receiving unit 22 receives GPS signals to obtain the location information of the portable terminal 20. The operation information input unit 23 is composed of a touch screen and the like, and inputs the manual operation information performed by the operator. The network communication unit 24 is connected to a general wide area network. The terminal storage unit 25 stores information based on the instructions of the terminal control unit 27. The display unit 26 is composed of a liquid crystal screen that also serves as a touch screen used as the operation information input unit 23, and displays information based on the instructions of the terminal control unit 27.

[0029] The terminal control unit 27 includes a GPS information acquisition unit 271, an input information acquisition unit 272, and a terminal information processing unit 273. The GPS information acquisition unit 271 acquires the position information acquired by the GPS receiving unit 22. The input information acquisition unit 272 acquires the operator's operation information manually input from the operation information input unit 23.

[0030] When an instruction to set the position information of the air conditioner 10 is input from the operation information input unit 23 by manual operation of the operator, the terminal information processing unit 273 adds the acquisition classification information indicating whether the position information is the position information acquired from the GPS signal or the position information input by the operator's operation to the position information of the portable terminal 20 itself acquired by the GPS information acquisition unit 271 or the position information acquired by the input information acquisition unit 272, and transmits it to the outdoor unit 11 for storage as the installation position information of the air conditioner 10, more specifically, the outdoor unit 11. Furthermore, when an instruction to read the position information of the air conditioner 10 is input from the operation information input unit 23 by manual operation of the operator, the terminal information processing unit 273 transmits a request to read the position information to the air conditioner 10, and in response to the request, acquires the position information sent from the air conditioner 10 and stored in the air conditioner 10, stores it in the terminal storage unit 25, and outputs it to the display unit 26.

[0031] <Operation of Air Conditioner Management System According to One Embodiment>

[0032] Reference Figure 4 and Figure 7 The operation of the air conditioner management system 1 according to the present embodiment is described with reference to the flowchart. In the present embodiment, it is assumed that the portable terminal 20 carried by the operator X is the portable terminal 20X, and the portable terminal 20 carried by the operator Y is the portable terminal 20Y. Furthermore, when the outdoor unit 11 is manufactured, information related to the outdoor unit 11, such as the model name "MMY-MUP***", the serial number "12345678" and the unit number "U1 / 12HP", is written and stored in the outdoor storage unit 112c of the outdoor controller 112 of the outdoor unit 11.

[0033] First, when setting up the air conditioner 10, the operator X inputs the name of the building where the air conditioner 10 is set, "ABC Building No. 1 East", into the portable terminal 20X. When the portable terminal 20X is brought close to the outdoor unit 11, the outdoor unit antenna 111a of the NFC tag 111 becomes capable of NFC communication, and it is detected that the terminal control unit 27 of the portable terminal 20 and the control unit 112d of the outdoor controller 112 are in a state capable of NFC communication.

[0034] When it is detected that the NFC communication is possible, the control unit 112d obtains the model name "MMY-MUP***", the serial number "12345678" and the unit number "U1 / 12HP" of the outdoor unit 11 from the outdoor storage unit 112c, and sends them to the portable terminal 20 via the first communication unit 112a, the information input / output unit 111c and the outdoor unit antenna 111a. The portable terminal 20 obtains various information sent from the outdoor unit 11 via the terminal antenna 21 using the terminal information processing unit 273 of the terminal control unit 27, and displays it on the display unit 26.

[0035] When the portable terminal 20 and the outdoor unit 11 become capable of NFC communication ("Yes" in S1), when the operator X performs an operation to instruct setting the location information of the air conditioner 10 from the operation information input unit 23 of the portable terminal 20X, the information of the operation is obtained by the input information acquisition unit 272 of the terminal control unit 27 ("Yes" in S2).

[0036] When the input information acquisition unit 272 acquires information indicating the position information setting operation, the terminal information processing unit 273 instructs the GPS information acquisition unit 271 to acquire the position information by the GPS signal (S3). The GPS information acquisition unit 271 activates the GPS receiving unit 22 in response to the instruction to receive the GPS signal.

[0037] Here, when the GPS signal is normally received by the GPS receiving unit 22 and the location information (latitude and longitude information) of the portable terminal 20X is acquired based on the GPS signal (“Yes” in S4 ), the location information is acquired by the GPS information acquiring unit 271 and transmitted to the terminal information processing unit 273 .

[0038] When the position information is acquired, the terminal information processing unit 273 sets the acquisition classification information based on the bibliographic information attached to the position information. Here, the information indicating that the position information is acquired based on the GPS signal is set as the acquisition classification information. Then, the first display information 300 including the acquired position information and the acquisition classification information is displayed on the display unit 26 (S5). Figure 5 An example of the first display information 300 displayed on the display unit 26 is shown.

[0039] exist Figure 5In the first display information 300 shown, "ABC Building No.1East" is displayed as the building name information 301 input by the operator X, "MMY-MUP***" is displayed as the model name information 302 of the outdoor unit 11 obtained from the outdoor unit 11, "12345678" is displayed as the serial number 303, "U1 / 12HP" is displayed as the unit number 304, "35.149972" is displayed as the latitude information 305 of the position information obtained by the GPS information acquisition unit 271, "138.554495" is displayed as the longitude information 306, and "GPS" is displayed as the acquisition classification information 307 indicating that the position information is obtained based on the GPS signal.

[0040] Furthermore, the display unit 26 (display screen) displays Figure 5 The first display information 300 includes information of a "return" button 308, a "save" button 309, a "send" button 310, and a "read" button 311. The "return" button 308 is a button for returning the display of the display unit 26 of the portable terminal 20 from the screen of the first display information 300 to the previous display screen. The "save" button 309 is a button for storing the position information displayed by the first display information 300 in the terminal storage unit 25. The "send" button 310 is a button for sending the information displayed by the first display information 300 to the outdoor unit 11. The "read" button 311 is a button for reading the position information stored in the outdoor unit 11.

[0041] Here, when the operator X operates the "Save" button 309 to instruct to save the location information ("Yes" in S6), the terminal information processing unit 273 adds the flag F=1 to the acquired location information as acquisition classification information indicating that the location information is location information acquired from the GPS signal, and stores it in the terminal storage unit 25 (S7).

[0042] Furthermore, when the GPS receiving unit 22 cannot normally receive the GPS signal in step S4 and the terminal information processing unit 273 cannot obtain the location information with the help of the GPS signal ("No" in S4), information prompting the operator X to input the location information is output to the display unit 26, such as prompt information such as "The location information cannot be obtained. Please use the keyboard to input the location information".

[0043] The operator X confirms the prompt information displayed on the display unit 26, obtains the position information of the current position by means other than the means of obtaining the position information by using the GPS signal, and manually inputs it from the operation information input unit 23. The position information obtained by means other than the means of obtaining the position information by using the GPS signal is, for example, the position information in which the operator X reads the latitude and longitude information of the current position from the map information displaying the latitude and longitude information. Although the position information thus obtained and manually input by the operator X is often less accurate than the position information obtained by using the GPS signal, the approximate position can be determined. The position information input by the operation of the operator X is obtained by the input information acquisition unit 272 and transmitted to the terminal information processing unit 273.

[0044] When the position information input by the operator X is acquired ("Yes" in S8), the terminal information processing unit 273 sets the acquisition classification information based on the bibliographic information of the position information. Here, the information indicating that the position information is manually input is set as the acquisition classification information. Then, the second display information 400 including the acquired position information and the acquisition classification information is displayed on the display unit 26 (S9). In this case, Figure 6 An example of the second display information 400 displayed on the display unit 26 (display screen) is shown in . If the operator X does not perform any operation (No in S8), the process ends here.

[0045] exist Figure 6 In the second display information 400 shown, building name information 401 "ABC Building No. 1 East", model name information 402 "MMY-MUP***" of the outdoor unit 11, serial number 403 "12345678", and unit number 404 "U1 / 12HP" are displayed. In addition, "35.1" is displayed as latitude information 405 of the position information manually input by the operator X, "138.6" is displayed as longitude information 406, and "manual" is displayed as acquisition classification information 407 indicating that the position information is manually input by the operator. Figure 5 Similarly, the second display information 400 includes information on a “return” button 408 , a “save” button 409 , a “send” button 410 , and a “read” button 411 .

[0046] Here, when the operator X operates the "Save" button 409 to instruct to save the position information ("Yes" in S10), the terminal information processing unit 273 adds the flag F=0 to the acquired position information as acquisition classification information indicating that the position information is position information input by the operation of the operator X, and stores it in the terminal storage unit 25 (S11).

[0047] Next, when the operator X operates the "transmit" button 410 to instruct transmission of the position information (Yes in S12), the terminal information processing unit 273 transmits the position information to the outdoor unit 11 of the air conditioner 10 via the terminal antenna 21 (S13).

[0048] In the outdoor unit 11, the location information transmitted from the portable terminal 20X is received via the outdoor unit antenna 111a, and is stored in the nonvolatile memory 111b by the information input / output unit 111c of the NFC tag 111. Furthermore, the stored location information is transmitted to the outdoor controller 112 by the information input / output unit 111c, and is stored in the outdoor storage unit 112c as the location information of the air conditioner 10 by the control of the control unit 112d.

[0049] Reference Figure 7 The flowchart of will explain the operation when another operator Y who visits the air conditioner 10 reads the position information using the portable terminal 20Y after the position information of the air conditioner 10 is stored in the outdoor unit 11. Figure 7 The flowchart of FIG. 1 shows in parallel the control flow of each of the mobile terminal 20 and the outdoor unit 11 which operate in association with each other.

[0050] When the operator Y brings the portable terminal 20Y close to the outdoor unit antenna 111a of the outdoor unit 11 to enable NFC communication ("Yes" in S21, "Yes" in S22), and instructs the operation of reading the location information of the air conditioner 10 from the operation information input unit 23 of the portable terminal 20Y ("Yes" in S23), the input information acquisition unit 272 acquires the information of the request operation to read the location information. The terminal information processing unit 273 sends the request to read the location information to the outdoor unit 11 of the air conditioner 10 via the terminal antenna 21 (S24). In addition, if NFC communication cannot be performed between the portable terminal 20Y and the outdoor unit 11 for some reason, the processing is terminated ("No" in S21, "No" in S22). And, if the operation of requesting to read the location information is not performed using the portable terminal 20Y ("No" in S23), the processing is terminated.

[0051] In the outdoor unit 11, the request for reading the location information sent from the portable terminal 20Y is received via the outdoor unit antenna 111a and transmitted to the control unit 112d. The control unit 112d reads the location information of the air conditioner 10 from the outdoor storage unit 112c in response to the received request for reading the location information, and transmits it to the portable terminal 20Y via the outdoor unit antenna 111a of the NFC tag 111 (S25).

[0052] In the portable terminal 20Y, the location information of the air conditioner 10 transmitted from the outdoor unit 11 is received via the terminal antenna 21, and stored in the terminal storage unit 25 through the terminal information processing unit 273. At the same time, if the flag F attached to the location information is 1, the display unit 26 displays the same Figure 5 Similarly, the first display information 300, if the flag F is 0, will display the same Figure 6 The same second display information 400 (S26).

[0053] Here, when the information displayed on the display unit 26 is the second display information 400, the operator Y determines that since the location information is manually input, there is a possibility that the accuracy is low, and obtains the location information using the GPS signal again, and executes the processing of updating the location information stored in the outdoor unit 11.

[0054] When the operator Y performs an operation to instruct setting the position information of the air conditioner 10 from the operation information input unit 23 of the portable terminal 20Y in order to update the position information stored in the outdoor unit 11, the information of the operation is acquired by the input information acquisition unit 272 of the terminal control unit 27 ("Yes" in S27). After that, since the processing performed in steps S28 to S35 is the same as the processing of steps S3 to S7, S12, and S13 described above, detailed description is omitted.

[0055] By updating the manually input position information stored in the outdoor unit 11 with the position information using the GPS signal in this manner, when another operator subsequently visits the air conditioner 10 , the operator can acquire highly accurate position information from the air conditioner 10 .

[0056] In addition, if the location information cannot be obtained by the GPS signal in step S29 ("No" in S29), the update process of the location information is not performed, and the process returns to step S21. In addition, if the location information already stored by the air conditioner is information obtained based on the GPS signal, the operator does not perform an operation to instruct setting the location information ("No" in S27), and the process of setting the location confirmation ends.

[0057] In the above embodiment, when the answer is "yes" in step S4 or "yes" in step S29, when the terminal information processing unit 273 acquires the location information, the reliability information of the GPS signal, which is generated by the portable terminal 20 based on the GPS signal and indicates the reliability of the acquired location information, may be used as the acquisition classification information. The reliability information of the GPS signal is information added to the GPS signal by the existing technology. On the other hand, the manually input location information acquired in step S8 ("yes") does not include such reliability information.

[0058] In this case, if the acquired location information has reliability information attached, the terminal information processing unit 273 determines that the location information is acquired through GPS signals, and if no reliability information is attached, it determines that the location information is manually input by the operator.

[0059] Furthermore, the terminal information processing unit 273 may have map information, generate display information showing the acquired position information of the air conditioner 10 on the map information in a display format differentiated according to the acquisition classification information added to the position information, and display the display information on the display unit 26 .

[0060] For example, when the acquisition classification information of the location information is "GPS", the terminal information processing unit 273 may Figure 8 As shown in FIG. 1 , a circle S1 is displayed on the map information M with the position P1 of the position information as the center and the larger the reliability information is, the smaller the reliability information is. In addition, when the acquisition classification information of the position information is "manual", the terminal information processing unit 273 displays the position information as "manual". Fig. 9 As shown, one point centered at the position P2 of the position information is displayed on the map information M. The operator can determine whether the position information stored based on the display content on the map information M is "GPS" or "manual".

[0061] Furthermore, in the above-described embodiment, the location information of the air conditioner 10 stored in the portable terminals 20X and 20Y may be transmitted to the portable terminals of other operators via the wide area network from the network communication unit 24 by the operation of the operators X and Y. By transmitting the information in this way, the location information of the air conditioner 10 can be provided to the operators before they go to the location of the air conditioner 10.

[0062] According to the above embodiment, even if the location of the air conditioner cannot receive GPS information, the location information of the air conditioner can be input and saved. Furthermore, if the accuracy of the stored location information of the air conditioner is low, it can be updated to information with high accuracy. By reading the acquired location information of the air conditioner using the portable terminal carried by the operator, the operator can easily go to the location of the air conditioner during subsequent maintenance and inspection using the acquired location information.

[0063] In addition, although in the above-mentioned embodiment, the outdoor unit 11 stores the location information obtained from the portable terminal 20 in the outdoor storage unit 112c, it can also be stored only in the non-volatile memory 111b of the NFC tag 111. In response to a request for reading location information from the portable terminal 20, the control unit 112d reads the location information stored in the non-volatile memory 111b via the first communication unit 112a and the information input / output unit 111c and sends it to the portable terminal 20.

[0064] Although the embodiments of the present invention have been described, the embodiments are only presented as examples and do not limit the scope of the invention. The new embodiments can be implemented in various other ways, and various omissions, substitutions and changes can be made within the scope of the invention. The embodiments and their variations are not only included in the scope and purpose of the invention, but also included in the invention recorded in the scope of the claims and their equivalents.
