空気調和機のメンテナンスシステムおよび空気調和機のメンテナンス方法Air conditioner maintenance system and air conditioner maintenance method
　本発明は、空気調和機の制御データの書き換えを行う空気調和機のメンテナンスシステムおよび空気調和機のメンテナンス方法に関する。 The present invention relates to an air conditioner maintenance system and an air conditioner maintenance method for rewriting control data of an air conditioner.
　通常、空気調和機が工場から出荷される時点で当該空気調和機の制御基板上のマイクロコンピュータ（以下、「マイコン」という。）に当該空気調和機の運転のためのプログラム（以下、「運転プログラム」という。）が書き込まれており、制御基板上のＥＥＰＲＯＭ（Electrically　Erasable　Programmable　Read-Only　Memory）（登録商標）といったメモリに当該空気調和機の機種に固有の制御データが書き込まれている。制御データは、たとえば、当該空気調和機の機種を判別させるための機種情報と、当該空気調和機のアクチュエータを動作させるためのパラメータとを含む。上述した制御データは空気調和機の機種毎に固有である。制御データがメモリに書き込まれた制御基板を用意しておく場合、制御データは空気調和機の機種毎に異なるため、制御基板のハードウェアが同一であったとしても、制御基板を空気調和機の機種毎に分けておく必要がある。 Usually, when an air conditioner is shipped from the factory, a microcomputer (hereinafter referred to as “microcomputer”) on the control board of the air conditioner is operated with a program (hereinafter referred to as “operation program”). ")", And control data specific to the model of the air conditioner is written in a memory such as EEPROM (Electrically Erasable Programmable Read-Only Memory) (registered trademark) on the control board. The control data includes, for example, model information for discriminating the model of the air conditioner and parameters for operating the actuator of the air conditioner. The control data described above is unique to each air conditioner model. When preparing the control board with the control data written in the memory, the control data differs depending on the model of the air conditioner, so even if the hardware of the control board is the same, the control board is attached to the air conditioner. It is necessary to divide each model.
　たとえば、客先で空気調和機に不具合が発生し、客先へサービスマンが当該空気調和機の修理に赴く場合、サービスマンが当該空気調和機の機種に対応した交換用の制御基板（以下、交換用の制御基板を「サービス基板」という。）を持っていく必要があるときは、サービスマンは当該サービス基板を事前に入手しておく必要があり、サービスマンの負担になっていた。また、空気調和機の製造メーカ側も、空気調和機の機種毎に対応するサービス基板の在庫を持つ必要があり、製造メーカ側の負担になっていた。 For example, if a problem occurs in an air conditioner at a customer, and a service person goes to the customer to repair the air conditioner, the service person will replace the control board corresponding to the model of the air conditioner (hereafter, When it is necessary to bring a control board for replacement into a "service board"), it is necessary for the service person to obtain the service board in advance, which is a burden on the service person. Also, the manufacturer of the air conditioner needs to have a stock of service boards corresponding to each air conditioner model, which is a burden on the manufacturer.
　特許文献１に記載の発明では、サービスマンが汎用の携帯情報端末を使用して、上述したメモリ内の機種情報の書き換えを可能としている。これにより、機種情報が異なる空気調和機の機種間においても、サービス基板の共通化が実現される。 In the invention described in Patent Document 1, the service person can rewrite the model information in the memory using a general-purpose portable information terminal. Thereby, the common use of the service board is realized among the air conditioner models having different model information.

FIG. 3 is a sequence diagram of a rewrite process executed by the air conditioner maintenance system of FIG.
　ステップＳ１０１において、携帯情報端末４０の通信部４０３は、インターネット６０を経由してメンテナンスサーバ５０から空気調和機１０の機種に固有の制御データをダウンロードする。 In step S101, the communication unit 403 of the portable information terminal 40 downloads control data specific to the model of the air conditioner 10 from the maintenance server 50 via the Internet 60.
　次いで、携帯情報端末４０の記憶部４０２は、ステップＳ１０１でダウンロードされた制御データを記憶する（ステップＳ１０２）。 Next, the storage unit 402 of the portable information terminal 40 stores the control data downloaded in step S101 (step S102).

The receiving unit 204 of the indoor unit 20 receives the control data transmitted in step S103.
　次いで、室内機２０の第２の記憶部２０３は、ステップＳ１０３で送信された制御データを記憶する（ステップＳ１０４）。 Next, the second storage unit 203 of the indoor unit 20 stores the control data transmitted in step S103 (step S104).
　次いで、室内機２０の通信部２０５は、ステップＳ１０３で送信された制御データを室外機３０へ送信する（ステップＳ１０５）。室外機３０の通信部３０４は、ステップＳ１０５で送信された制御データを受信する。 Next, the communication unit 205 of the indoor unit 20 transmits the control data transmitted in step S103 to the outdoor unit 30 (step S105). The communication unit 304 of the outdoor unit 30 receives the control data transmitted in step S105.
　次いで、室外機３０の書換部３０５は、第２の記憶部３０３の内容をステップＳ１０５で送信された制御データの内容に書き換えて（ステップＳ１０６）、本処理を終了する。 Next, the rewriting unit 305 of the outdoor unit 30 rewrites the content of the second storage unit 303 with the content of the control data transmitted in step S105 (step S106), and ends this process.
　図３に示した書き換え処理によれば、室外機３０の制御基板のメモリ３２の内容がメンテナンスサーバ５０にアップロードされた制御データの内容に書き換えられる。これにより、異なる機種間で室外機３０の制御基板のハードウェアが同一であれば、制御基板を空気調和機１０の機種毎に分けておく必要がなくなり、すなわち機種が異なっていてもサービス基板は共通となるため、空気調和機１０の室外機３０の制御基板の共通化を実現することができる。 3, the contents of the memory 32 of the control board of the outdoor unit 30 are rewritten with the contents of the control data uploaded to the maintenance server 50. Thereby, if the hardware of the control board of the outdoor unit 30 is the same between different models, it is not necessary to divide the control board for each model of the air conditioner 10, that is, the service board is different even if the models are different. Since it becomes common, the sharing of the control board of the outdoor unit 30 of the air conditioner 10 can be realized.
　図３に示した書き換え処理によれば、汎用の携帯情報端末４０を用いて、制御データのダウンロード、および室外機３０の制御基板上のメモリ３２の内容の書換えが可能となるため、客先へサービスマンが空気調和機１０の修理に赴く場合、ハードウェアが同一であるサービス基板を持っていれば、事前に空気調和機１０の機種に対応したサービス基板を用意する必要がなくなり、急な制御基板の交換にも対応することができる。 According to the rewriting process shown in FIG. 3, the control data can be downloaded and the contents of the memory 32 on the control board of the outdoor unit 30 can be rewritten using the general-purpose portable information terminal 40.

It is also possible to deal with the replacement of the substrate.
　図３に示した書き換え処理によれば、室外機３０の制御基板上のメモリ３２の内容を書き換えることができるため、制御データの更新も可能になる。 According to the rewriting process shown in FIG. 3, the contents of the memory 32 on the control board of the outdoor unit 30 can be rewritten, so that the control data can be updated.
　図３に示した書き換え処理では、室内機２０が汎用の携帯情報端末４０から書き換え用の制御データを受信してから、一定時間は空気調和機１０を空気調和機１０のリモコン１２から送信される運転信号を受け付けない書き換えモードになるように設定しておくことが好ましい。これにより、メモリ３２の内容を制御データの内容へ書き換えている最中に空気調和機１０のリモコン１２から送信される運転信号を受信することによる誤動作を抑制することができる。 In the rewriting process shown in FIG. 3, after the indoor unit 20 receives the control data for rewriting from the general-purpose portable information terminal 40, the air conditioner 10 is transmitted from the remote controller 12 of the air conditioner 10 for a certain period of time. It is preferable to set the rewriting mode so as not to accept the operation signal. Thereby, malfunction by receiving the operation signal transmitted from the remote control 12 of the air conditioner 10 while rewriting the content of the memory 32 to the content of the control data can be suppressed.
