- the rewrite unit 140 is realized by the CPU 60 executing a rewrite control program.
- the reception processing unit 120 determines whether or not the rewriting process is being executed by the rewriting unit 140 when the data receiving unit 110 receives the update data CON ′. If the rewriting process is in progress, the reception processing unit 120 discards the received update data CON ′.

- the reception processing unit 120 is realized by the CPU 60 executing a rewrite control program.
- the notification unit 150 notifies the user that the rewriting process by the rewriting unit 140 is completed.
- the notification unit 150 is realized by the display device 20 or the notification device 30.
- FIG. 5 is a flowchart showing rewrite control of the control data CON in the present embodiment.
- Step S1 The air conditioner 1 is powered on.
- the controller 40 performs a power-on reset.
- Step S2 The data receiving unit 110 waits for update data CON ′ sent from the transmitter 2 by wireless communication (step S2; No). When the update data CON ′ is received (step S2; Yes), the data receiving unit 110 passes the received update data CON ′ to the reception processing unit 120. Thereafter, the process proceeds to step S3.
- Step S3 When receiving the update data CON ′, the reception processing unit 120 determines whether or not the rewriting process is being executed by the rewriting unit 140. If the rewriting process is in progress (step S3; Yes), the process proceeds to step S10, and the reception processing unit 120 discards the received update data CON ′. On the other hand, if the rewriting process is not in progress (step S3; No), the process proceeds to step S4.
- Step S4 The reception processing unit 120 stores the received update data CON ′ in the buffer unit 210.
- the buffer unit 210 By using the buffer unit 210, it is possible to support high-speed reception of the update data CON ′ through wireless communication.
- the process proceeds to step S5.
- Step S5 The rewriting unit 140 performs a rewriting process. That is, the rewriting unit 140 rewrites (updates) the control data CON stored in the control data storage unit 220 with the update data CON ′ stored in the buffer unit 210. When the rewriting process is completed, the process proceeds to step S6.
- Step S6 The notification unit 150 notifies the user of completion of the rewriting process. For example, the notification unit 150 displays completion on the display or sounds a buzzer.
- the update data CON ' is sent from the transmitter 2 to the air conditioner 1 by wireless communication.
- the air conditioner 1 rewrites the control data CON based on the update data CON ′ received from the transmitter 2.
- Such use of wireless communication is excellent in terms of work efficiency. Further, if a high-speed wireless communication network such as a wireless LAN is used, the update data CON 'can be distributed to a large number of air conditioners 1 at high speed, which is preferable. In addition, since the air conditioner 1 includes the buffer unit 210 for temporarily storing the update data CON ', it is possible to support high-speed reception of the update data CON'.
- the air conditioner 1 has a function of determining whether or not the rewriting process is being performed when the update data CON ′ is received. If the rewriting process is in progress, the received update data CON 'is discarded. Since the air conditioner 1 has such a function, the transmitter 2 can transmit the update data CON ′ a plurality of times (see FIG. 2). Even if the air conditioner 1 continuously receives the update data CON ′, the subsequent update data CON ′ does not interfere with the rewrite process as long as the rewrite process is being executed normally.
- the transmitter 2 transmits the update data CON ′ a plurality of times when the wireless communication is interrupted. Even if the wireless communication is interrupted in a certain period, the update data CON 'is transmitted a plurality of times, so that the probability that the air conditioner 1 normally receives the update data CON' is extremely high. Accordingly, rewrite errors when rewriting the control data CON via wireless communication are reduced. In other words, the reliability of the air conditioner 1 is improved.
- the air conditioner 1 determines whether to permit or prohibit the “rewriting process” by the rewriting unit 140 based on a predetermined criterion.
- a predetermined criterion for example, whether or not the received update data CON ′ is for the own model can be mentioned. That is, the air conditioner 1 permits rewriting of the control data CON only when the received update data CON ′ is for its own model.
- an ID code (identification information) is assigned to the air conditioner 1 in advance.
- the ID code is different for each model of the air conditioner 1.
- the update data CON ′ transmitted from the transmitter 2 is given the ID code of the air conditioner 1 that is the target of the rewriting process.

- the ID storage unit 230 is realized by the mask ROM 73 or the nonvolatile memory 71.
- the rewrite determination unit 130 determines whether to permit or prohibit the “rewrite process” by the rewrite unit 140. When permitted by the rewrite determination unit 130, the rewrite unit 140 executes a rewrite process. When prohibited by the rewrite determination unit 130, the rewrite unit 140 does not execute the rewrite process.
- the rewrite determination unit 130 is realized by the CPU 60 executing a rewrite control program.
- the rewrite determining unit 130 includes a type determining unit 131.
- the type determination unit 131 determines whether or not the received update data CON ′ is for the own model. Specifically, the type determination unit 131 determines whether or not the ID code given to the received update data CON ′ matches the ID code stored in the ID storage unit 230. If the ID codes match, the type determination unit 131 determines that the received update data CON ′ is for the own model, and the rewrite determination unit 130 permits the rewrite process. On the other hand, if the ID codes do not match, the type determination unit 131 determines that the received update data CON ′ is not for the own model, and the rewrite determination unit 130 prohibits the rewrite processing.
- FIG. 8 is a flowchart showing rewrite control of control data CON in the present embodiment.
- the description which overlaps with the above-mentioned Embodiment 1 is abbreviate
- steps S7 and S8 are added as compared with the first embodiment.
- Step S7 The rewrite determination unit 130 determines whether to permit or prohibit the “rewrite process” by the rewrite unit 140. More specifically, the type determination unit 131 determines whether or not the ID code assigned to the received update data CON ′ matches the ID code stored in the ID storage unit 230.
- the type determination unit 131 determines that the received update data CON 'is for the own model. In this case, the rewrite determining unit 130 permits the rewrite process (step S7; Yes). Thereafter, the process proceeds to step S5, and the rewriting unit 140 executes the rewriting process.
- step S7 determines that the received update data CON ′ is not for the own model.
- the rewrite determining unit 130 prohibits the rewrite process (step S7; No). Thereafter, the process proceeds to step S8.
- Step S8 The notification unit 150 notifies the user that the rewriting process has not been performed. For example, the notification unit 150 displays on the display that the rewriting process has not been performed, or sounds a buzzer. Thereafter, the process proceeds to step S10, and the rewrite determining unit 130 discards the received update data CON ′. In this case, the rewriting process by the rewriting unit 140 is not executed.
- steps S7 and S8 are performed after step S4. However, as long as it is between step S2 and step S5, steps S7 and S8 may be performed at any timing.

- the predetermined reference is whether or not the elapsed time from power ON (original power ON) of the air conditioner 1 exceeds a certain time. When the elapsed time exceeds a certain time, the air conditioner 1 “prohibits” rewriting of the control data CON.

Abstract
Description
図1は、本発明の実施の形態1に係る空気調和機システムを示す概略図である。空気調和機システムは、空気調和機1と送信機2を備えている。空気調和機1と送信機2とは、互いに無線通信可能なように接続されている。例えば、空気調和機1と送信機2は、無線LAN等の高速無線通信ネットワークを介して、互いに接続されている。
空気調和機1がパワーONされる。コントローラ40は、パワーオンリセットする。
データ受信部110は、送信機2から無線通信によって送られてくる更新データCON’を待つ(ステップS2;No)。更新データCON’を受信すると(ステップS2;Yes)、データ受信部110は、受信した更新データCON’を受信処理部120に渡す。その後、処理はステップS3に進む。
更新データCON’を受け取ると、受信処理部120は、書き換え部140によって書き換え処理が実行されている最中か否かを判定する。書き換え処理の最中であれば(ステップS3;Yes)、処理はステップS10に進み、受信処理部120は、受信した更新データCON’を破棄する。一方、書き換え処理の最中でなければ(ステップS3;No)、処理はステップS4に進む。
受信処理部120は、受信した更新データCON’をバッファ部210に格納する。バッファ部210を利用することにより、無線通信を通した更新データCON’の高速受信にも対応することが可能である。バッファ部210への更新データCON’の格納が完了すると、処理はステップS5に進む。
書き換え部140は、書き換え処理を実施する。つまり、書き換え部140は、バッファ部210に格納された更新データCON’で、制御データ格納部220に格納される制御データCONを書き換える(更新する)。書き換え処理が完了すると、処理はステップS6に進む。
通知部150は、書き換え処理の完了をユーザに通知する。例えば、通知部150は、完了をディスプレイに表示したり、ブザーを鳴動させたりする。
本発明の実施の形態2では、空気調和機1は、書き換え部140による「書き換え処理」を許可するか禁止するかを、所定の基準に基づいて決定する。その所定の基準として、例えば、受信した更新データCON’が自機種用か否かが挙げられる。つまり、受信した更新データCON’が自機種用である場合のみ、空気調和機1は、制御データCONの書き換えを許可する。
書き換え決定部130は、書き換え部140による「書き換え処理」を許可するか禁止するかを決定する。より詳細には、種別判定部131は、受信した更新データCON’に付与されたIDコードがID格納部230に格納されているIDコードと一致するか否かを判定する。
通知部150は、書き換え処理が実施されなかったことをユーザに通知する。例えば、通知部150は、書き換え処理が実施されなかったことをディスプレイに表示したり、ブザーを鳴動させたりする。その後、処理はステップS10に進み、書き換え決定部130は、受信した更新データCON’を破棄する。この場合、書き換え部140による書き換え処理は実行されない。
本発明の実施の形態3でも、空気調和機1は、書き換え部140による「書き換え処理」を許可するか禁止するかを、所定の基準に基づいて決定する。本実施の形態では、その所定の基準は、空気調和機1のパワーON(元電源ON)からの経過時間が一定時間を超えたか否かである。その経過時間が一定時間を超えた場合、空気調和機1は、制御データCONの書き換えを“禁止”する。
図10は、本発明の実施の形態4に係る空気調和機1の機能構成を示すブロック図である。上述の実施の形態1,2と重複する説明は適宜省略される。
既出の実施の形態2~4を適宜組み合わせることも可能である。例えば、図11は、既出の実施の形態2~4の全てを組み合わせた場合を示している。
既出の実施の形態において、データ受信部110は、特定周波数の無線信号のみを受信可能であってもよい。その特定周波数は、空気調和機1の機種毎に異なる値に設定される。送信機2は、所望の機種に割り当てられた特定周波数の無線信号によって、更新データCON’を送信する。これにより、同一エリア内に複数の機種が混在する場合に、所望の機種に対してだけ選択的に制御データCONの書き換えを実施することが可能となる。
