　次に、本発明の第１実施形態による書き換えシステム１の処理について説明する。
　ここでは、図５に示す書き換え処理フローについて説明する。
　空調システム１０のソフトウェアを書き換えるために、作業担当者は、書き換え装置２０を空調制御通信ネットワークに接続する。 Next, processing of the rewriting system 1 according to the first embodiment of the present invention will be described.
Here, the rewrite processing flow shown in FIG. 5 will be described.
In order to rewrite the software of the air conditioning system 10, the worker in charge connects the rewriting device 20 to the air conditioning control communication network.
　作業担当者は、書き換え装置２０に対して書換えプログラム（すなわち、更新するソフトウェア）を選択する操作を行う。前述のように各機器は、ソフトウェアのバージョンと関連付けられている。よって、書換えプログラムを選択することは、更新対象となる機器の機種を選択することに等しい。 The person in charge of the operation performs an operation of selecting a rewriting program (that is, software to be updated) with respect to the rewriting device 20. As described above, each device is associated with a software version. Therefore, selecting the rewriting program is equivalent to selecting the model of the device to be updated.
　機器情報取得部２０１は、作業担当者による操作に応じて、通信ネットワークより接続空調機器情報を取得する。機器情報取得部２０１は、取得した接続空調機器情報を記憶部２０４に記憶させる。 The device information acquisition unit 201 acquires the connected air conditioning device information from the communication network according to the operation by the worker. The device information acquisition unit 201 causes the storage unit 204 to store the acquired connected air conditioning device information.
　機器選定部２０２は、記憶部２０４から接続空調機器情報を読み出す。機器選定部２０２は、読み出した接続空調機器情報と、書換えプログラムとに基づいて、プログラムの更新が未実施である機器の有無を判定する。例えば、機器選定部２０２は、接続空調機器情報において、書換えプログラムよりもバージョンの古いプログラムの機器が有る場合に、プログラムの更新が未実施である機器が有ると判定する。また、機器選定部２０２は、接続空調機器情報において、書換えプログラムよりもバージョンの古いプログラムの機器が無い場合に、プログラムの更新が未実施である機器が無いと判定する。 The device selection unit 202 reads the connected air conditioning device information from the storage unit 204. The device selection unit 202 determines the presence / absence of a device that has not been updated based on the read connection air conditioning device information and the rewriting program. For example, the device selection unit 202 determines that there is a device whose program has not been updated when there is a device whose program is older than the rewriting program in the connected air conditioning device information. The device selection unit 202 determines that there is no device that has not been updated when there is no device whose program is older than the rewriting program in the connected air conditioning device information.
　機器選定部２０２は、プログラムの更新が未実施である機器が無いと判定した場合、処理を終了する。なお、作業担当者は、別の書換えプログラムがある場合には、新たに書換えプログラムを選択しても良い。 If the device selection unit 202 determines that there is no device for which the program has not been updated, the processing ends. If there is another rewriting program, the worker in charge may select a new rewriting program.
　また、機器選定部２０２は、プログラムの更新が未実施である機器が有ると判定した場合、優先順位によるプログラムを更新する機器を選定する処理を行う。 In addition, when it is determined that there is a device for which the program has not been updated, the device selection unit 202 performs a process of selecting a device for updating the program according to the priority order.
　更新部２０３は、機器選定部２０２によってソフトウェアを更新する対象に選定された機器（例えば、図１における室内機１０５）のプログラムを更新する（ステップＳ１）。ここで、書き換え装置２０は、空調制御通信ネットワークとの接続を解除する。 The update unit 203 updates the program of the device (for example, the indoor unit 105 in FIG. 1) selected as a target for software update by the device selection unit 202 (step S1). Here, the rewriting device 20 releases the connection with the air conditioning control communication network.
　このときの書き換えシステム１では、図６（ａ）に示す室内機１０５のみが接続空調機器情報を取得作成し、他の空調機器のプログラムの更新作業を開始できる状態になっている（ステップＳ２）。 In the rewriting system 1 at this time, only the indoor unit 105 shown in FIG. 6A is in a state where it can acquire and create the connected air conditioner information, and can start updating the program of other air conditioners (step S2). .
　通信部１００１は、ソフトウェアを更新する機器探索のため、他機器のネットワーク接続を確認し（ステップＳ３）、他機器の通信ネットワーク接続を判断する（ステップＳ４）。 The communication unit 1001 confirms the network connection of the other device (step S3) and determines the communication network connection of the other device (step S4) in order to search for a device for updating the software.
　機器選定部１００２は、通信部１００１が取得した接続空調機器情報において、室内機１０５と同一の機種が有った場合（ステップＳ４において「有り」）、その機器のソフトウェアのバージョンと、更新しようとしているソフトウェアのバージョンとを比較し、バージョンが一致しているか否かを判定する（ステップＳ５）。
　機器選定部１００２は、バージョンが一致していると判定した場合（ステップＳ５において「一致」）、すべての機器の機器番号（通信アドレス）についてソフトウェアの更新の確認が完了したか否かを判定する（ステップＳ６）。
　機器選定部１００２は、ソフトウェアの更新の確認が完了したと判定した場合（ステップＳ６において「完了」）、プログラムの更新作業を完了する（ステップＳ７）。
　また、機器選定部１００２は、全ての通信ネットワーク接続機器におけるソフトウェアの更新の確認が完了していないと判定した場合（ステップＳ６において「未完」）、ステップＳ４の処理に戻す。 If there is the same model as the indoor unit 105 in the connected air conditioning device information acquired by the communication unit 1001 (“Yes” in step S4), the device selection unit 1002 tries to update the software version of the device. The software version is compared to determine whether the versions match (step S5).
If the device selection unit 1002 determines that the versions match (“match” in step S5), the device selection unit 1002 determines whether or not software update confirmation has been completed for the device numbers (communication addresses) of all devices. (Step S6).
If the device selection unit 1002 determines that the confirmation of the software update has been completed (“complete” in step S6), the device selection unit 1002 completes the program update operation (step S7).
In addition, when the device selection unit 1002 determines that the software update confirmation has not been completed for all the communication network connection devices (“incomplete” in step S6), the device selection unit 1002 returns to the process of step S4.
　機器選定部１００２は、接続空調機器情報において、室内機１０５と同一の機種が無かった場合（ステップＳ４において「無し」）、ステップＳ６の処理に進める。 If the same model as the indoor unit 105 is not found in the connected air conditioning device information (“No” in step S4), the device selection unit 1002 proceeds to the process of step S6.
　機器選定部１００２は、バージョンが一致していないと判定した場合（ステップＳ５において「不一致」）、対象となる機器（例えば、図６に示す室内機１０６）に対してプログラムの書き換えを実施する準備を行う（ステップＳ８）。
　更新部１００３は、書き換えデータを対象となる機器に転送して、プログラムを書き換える処理を行う（ステップＳ９）。
　更新部１００３は、書き換え結果を確認し、接続空調機器情報を更新して、対象となる機器に対して機器をリセットする（すなわち、書き換えたプログラムを有効にする）指示を送信する（ステップＳ１０）。そして、更新部１００３は、ステップＳ４の処理に戻す。 If the device selection unit 1002 determines that the versions do not match (“mismatch” in step S5), the device selection unit 1002 prepares to rewrite the program for the target device (for example, the indoor unit 106 shown in FIG. 6). Is performed (step S8).
The update unit 1003 performs a process of rewriting the program by transferring the rewritten data to the target device (step S9).
The update unit 1003 confirms the rewriting result, updates the connected air conditioning device information, and transmits an instruction to reset the device (that is, to validate the rewritten program) to the target device (step S10). . And the update part 1003 returns to the process of step S4.
　更新部１００３から機器をリセットする指示を受信した機器は、プログラムを更新し、その後、接続空調機器情報に基づいて、図６（ｂ）に示すように、他のプログラムを更新する新たな機器として動作する。
　そして、室内機１０５の書き換え装置１００及び室内機１０６の書き換え装置１００のそれぞれは、図６（ｃ）に示すように、室内機１０７、室内機１０８のプログラムを更新する。室内機１０７と室内機１０８のそれぞれは、プログラムが更新されると、室内機１０５や室内機１０６と同様に他の機器のプログラムを書き換えられる状態になる。そして、例えば、図６（ｄ）に示すように、室内機１０５、室内機１０６、室内機１０７、室内機１０８は、室内機１０９、室内機１１０、室内機１１１、室内機１１２のプログラムを更新する。 The device that has received the instruction to reset the device from the updating unit 1003 updates the program, and thereafter, as a new device that updates other programs, as shown in FIG. Operate.
Then, each of the rewriting device 100 of the indoor unit 105 and the rewriting device 100 of the indoor unit 106 updates the programs of the indoor unit 107 and the indoor unit 108 as shown in FIG. When the program is updated, each of the indoor unit 107 and the indoor unit 108 is in a state where the programs of other devices can be rewritten in the same manner as the indoor unit 105 and the indoor unit 106. For example, as shown in FIG. 6D, the indoor unit 105, the indoor unit 106, the indoor unit 107, and the indoor unit 108 update the programs of the indoor unit 109, the indoor unit 110, the indoor unit 111, and the indoor unit 112.

＜第２実施形態＞
　本発明の第２実施形態による書き換えシステム１について説明する。
　本発明の第１実施形態による書き換えシステム１では、他の機器のプログラムを書き換え可能な各書き換え装置１００が個別に接続空調機器情報を取得/記憶し、記憶した接続空調機器情報に基づいてプログラムを書き換える機器を選定した。そのため、複数の異なる情報を有する接続空調機器情報が存在することとなり、すべての機器について処理が終わるまですべての接続空調機器情報が同一の情報とならない、すなわち、同一の処理を異なる機器が実行し無駄な処理が生じる可能性がある。更には、各書き換え装置１００が、書き換え作業を同時、多発的に実施することによる多大な通信トラフィックを生じさせ、通信ネットワークに障害を発生させる恐れがある。
　そこで、本発明の第２実施形態による書き換えシステム１では、１つのマスタとなる機器のみが他の機器へのプログラム書き換え実施可否を判断することにより、無駄な処理や多大な通信トラフィックを生じさせることを防止する。 Second Embodiment
A rewriting system 1 according to a second embodiment of the present invention will be described.
In the rewriting system 1 according to the first embodiment of the present invention, each rewriting device 100 capable of rewriting a program of another device individually acquires / stores the connected air conditioning device information, and executes the program based on the stored connected air conditioning device information. The device to be rewritten was selected. For this reason, there is connected air-conditioning equipment information having a plurality of different information, and all connected air-conditioning equipment information does not become the same information until processing is completed for all equipment, that is, different equipment executes the same processing. There is a possibility that useless processing may occur. Furthermore, there is a possibility that each rewriting device 100 generates a large amount of communication traffic due to simultaneous and frequent rewriting work, thereby causing a failure in the communication network.
Therefore, in the rewriting system 1 according to the second embodiment of the present invention, only one master device determines whether or not program rewriting to other devices can be performed, thereby causing unnecessary processing and a large amount of communication traffic. To prevent.
　本発明の第２実施形態による書き換えシステム１は、本発明の第１実施形態による書き換えシステム１と同様に、空調システム１０、書き換え装置２０を備える。 The rewriting system 1 according to the second embodiment of the present invention includes an air conditioning system 10 and a rewriting device 20 as in the rewriting system 1 according to the first embodiment of the present invention.
　空調システム１０は、室外機１０１、１０２、１０３、１０４、室内機１０５、１０６、１０７、１０８、１０９、１１０、１１１、１１２を備える。
　室外機１０１、１０２、１０３、１０４、室内機１０５、１０６、１０７、１０８、１０９、１１０、１１１、１１２のそれぞれは、書き換え装置１００を備える。
　書き換え装置１００は、図７に示すように、通信部１００１、機器選定部１００２、更新部１００３、記憶部１００４、問合せ部１００５、回答部１００６を備える。書き換え装置１００は、例えば、コンピュータである。
　問合せ部１００５は、プログラムを書き換える処理の実施可否をマスタとなる機器に問い合わせる。
　回答部１００６は、問合せ部１００５から問い合わせがあった場合に、接続空調機器情報に基づいてプログラムを書き換える処理の実施可否を回答する。 The air conditioning system 10 includes outdoor units 101, 102, 103, 104 and indoor units 105, 106, 107, 108, 109, 110, 111, 112.
Each of the outdoor units 101, 102, 103, 104 and the indoor units 105, 106, 107, 108, 109, 110, 111, 112 includes a rewriting device 100.
As shown in FIG. 7, the rewriting device 100 includes a communication unit 1001, a device selection unit 1002, an update unit 1003, a storage unit 1004, an inquiry unit 1005, and an answer unit 1006. The rewriting device 100 is, for example, a computer.
The inquiry unit 1005 inquires of the master device whether or not the process of rewriting the program can be performed.
When there is an inquiry from the inquiry unit 1005, the answer unit 1006 answers whether or not the process of rewriting the program based on the connected air conditioner information is possible.
　なお、書き換え装置２０によってプログラムが書き換えられた最初の空調機器は、問合せ部１００５の機能を無効にし、回答部１００６の機能を有効にする。そして、回答部１００６は、通信部１００１を介して他の機器にマスタ機器となることを報知する。
　マスタ機器からマスタ機器となることを報知された機器は、問合せ部１００５の機能を有効にし、回答部１００６の機能を無効にする。 Note that the first air conditioner whose program has been rewritten by the rewriting device 20 disables the function of the inquiry unit 1005 and enables the function of the response unit 1006. Then, the answer unit 1006 notifies other devices via the communication unit 1001 that it becomes a master device.
The device notified from the master device that it will become the master device enables the function of the inquiry unit 1005 and disables the function of the response unit 1006.
　次に、本発明の第２実施形態による書き換えシステム１の処理について説明する。
　ここでは、図８に示すマスタ機器とその他の機器との間の通信の処理フローについて説明する。
　なお、最初の更新機器は、書き換え装置２０によってプログラムが書き換えられた最初の空調機器であり、問合せ部１００５の機能を無効にし、回答部１００６の機能を有効にしているものとする。また、更新機器は、他の機器によってプログラムが書き換えられた機器であり、問合せ部１００５の機能を有効にし、回答部１００６の機能を無効にしているものとする。 Next, processing of the rewriting system 1 according to the second embodiment of the present invention will be described.
Here, a processing flow of communication between the master device and other devices shown in FIG. 8 will be described.
It is assumed that the first updated device is the first air-conditioning device whose program has been rewritten by the rewriting device 20, the function of the inquiry unit 1005 is invalidated, and the function of the answer unit 1006 is validated. The update device is a device whose program has been rewritten by another device, and the function of the inquiry unit 1005 is enabled and the function of the response unit 1006 is disabled.
　更新機器の機器選定部１００２は、プログラムが未更新である機器を検出する（ステップＳ１１）。そのため、更新機器の問合せ部１００５は、最初の更新機器に対して、プログラムの書き換え実施の可否を問い合わせる（ステップＳ１２）。このステップＳ１２の処理により、書き換え装置１００は、プログラムの更新対象機器のアドレスを確認することができる。 The device selection unit 1002 of the updated device detects a device whose program has not been updated (step S11). Therefore, the inquiry unit 1005 of the update device makes an inquiry to the first update device as to whether or not the program can be rewritten (step S12). By the processing in step S12, the rewriting device 100 can confirm the address of the program update target device.
　最初の更新機器の回答部１００６は、通信部１００１を介して更新機器からプログラムの書き換え実施の可否の問合せを受信する（ステップＳ１３）。最初の更新機器の回答部１００６は、通信トラフィック量をモニタする（ステップＳ１４）。最初の更新機器の回答部１００６は、プログラムの書き換え実施の可否を判定する（ステップＳ１５）。
　最初の更新機器の回答部１００６は、例えば、モニタした通信トラフィック量が所定のトラフィック量を示すしきい値を超えている場合、プログラムの書き換えはできないと判定し（ステップＳ１５において「否」）、書き換え作業の中止を更新機器に命令する（ステップＳ１６）。
　また、最初の更新機器の回答部１００６は、例えば、モニタした通信トラフィック量が所定のトラフィック量を示すしきい値を超えていない場合、プログラムの書き換えができると判定し（ステップＳ１５において「可」）、書き換え作業の実施を更新機器に命令する（ステップＳ１７）。 The reply unit 1006 of the first update device receives an inquiry as to whether or not program rewriting can be performed from the update device via the communication unit 1001 (step S13). The reply unit 1006 of the first update device monitors the communication traffic volume (step S14). The reply unit 1006 of the first update device determines whether or not the program can be rewritten (step S15).
For example, when the monitored communication traffic volume exceeds a threshold value indicating a predetermined traffic volume, the answer unit 1006 of the first update device determines that the program cannot be rewritten ("No" in step S15). The update device is instructed to stop the rewriting work (step S16).
Further, the answer unit 1006 of the first update device determines that the program can be rewritten when the monitored communication traffic volume does not exceed a threshold value indicating a predetermined traffic volume ("Yes" in step S15). ), The update device is commanded to perform the rewriting work (step S17).
　更新機器の機器選定部１００２は、最初の更新機器から書き換え作業の中止の命令を受信した場合（ステップＳ１８）、書き換え作業を中止し、書き換え処理に関する情報をクリアする（ステップＳ１９）。更新機器の機器選定部１００２は、一定時間待機した後、ステップＳ１１と同様にプログラムが未更新である機器を検出する処理を行う（ステップＳ２０）。そして、更新機器の問合せ部１００５は、最初の更新機器に対して、ステップＳ１２と同様に、プログラムの書き換え実施の可否を問い合わせる（ステップＳ２１）。 The device selection unit 1002 of the update device receives the instruction to cancel the rewrite work from the first update device (step S18), stops the rewrite work, and clears information related to the rewrite processing (step S19). The device selection unit 1002 for the updated device waits for a certain period of time, and then performs a process of detecting a device whose program has not been updated, similar to step S11 (step S20). Then, the inquiry unit 1005 of the update device makes an inquiry to the first update device as to whether or not the program can be rewritten, similarly to step S12 (step S21).
　更新機器の機器選定部１００２が最初の更新機器から書き換え作業の実施の命令を受信した場合（ステップＳ２２）、更新部１００３は、書き換え作業を開始し（ステップＳ２３）、書き換え作業を完了する（ステップＳ２４）。 When the device selection unit 1002 of the update device receives a rewrite operation execution command from the first update device (step S22), the update unit 1003 starts the rewrite operation (step S23) and completes the rewrite operation (step S22). S24).
　以上、本発明の第２実施形態による書き換えシステム１について説明した。本発明の第２実施形態による書き換えシステム１において、書き換え装置１００は、通信部１００１、機器選定部１００２、更新部１００３、記憶部１００４、問合せ部１００５、回答部１００６を備える。問合せ部１００５は、プログラムを書き換える処理の可否をマスタとなる機器に問い合わせる。回答部１００６は、問合せ部１００５から問い合わせがあった場合に、接続空調機器情報に基づいてプログラムを書き換える処理の可否を回答する。書き換え装置２０によってプログラムが書き換えられた最初の空調機器は、問合せ部１００５の機能を無効にし、回答部１００６の機能を有効にする。回答部１００６は、通信部１００１を介して他の機器にマスタ機器となることを報知する。マスタ機器からマスタ機器となることを報知された機器は、問合せ部１００５の機能を有効にし、回答部１００６の機能を無効にする。
　このように、最初の更新機器がマスタ機器となり、他の更新機器へプログラムを書き換える処理の可否の命令を送信することで、本発明の第１実施形態における書き換えシステム１に比べて更新機器による無駄な処理や通信トラフィック量が低減される。 The rewriting system 1 according to the second embodiment of the present invention has been described above. In the rewriting system 1 according to the second embodiment of the present invention, the rewriting device 100 includes a communication unit 1001, a device selection unit 1002, an update unit 1003, a storage unit 1004, an inquiry unit 1005, and an answer unit 1006. The inquiry unit 1005 inquires of the master device whether or not the process of rewriting the program is possible. When there is an inquiry from the inquiry unit 1005, the answer unit 1006 answers whether or not the process of rewriting the program based on the connected air conditioner information is possible. The first air conditioner whose program has been rewritten by the rewriting device 20 disables the function of the inquiry unit 1005 and enables the function of the response unit 1006. The reply unit 1006 notifies other devices that it will become the master device via the communication unit 1001. The device notified from the master device that it will become the master device enables the function of the inquiry unit 1005 and disables the function of the response unit 1006.
In this way, the first update device becomes the master device, and by sending an instruction to determine whether or not to rewrite the program to other update devices, the update device wastes more than the rewrite system 1 in the first embodiment of the present invention. Processing and communication traffic volume are reduced.
