Description

宅内機器制御装置、制御システム、宅内機器制御方法、およびプログラムHome device control apparatus, control system, home device control method, and program
　本発明は、ホームネットワークに接続された宅内機器を制御するための宅内機器制御装置、制御システム、宅内機器制御方法、およびプログラムに関するものである。 The present invention relates to a home device control apparatus, a control system, a home device control method, and a program for controlling a home device connected to a home network.
　デジタルネットワーク技術の進歩により、通信デバイスが安価で小型に実現可能となったため、今日ではさまざまな種類の機器がネットワークに接続されて動作するようになっている。家庭内に設置される電化製品についても、装置単体ではなく装置外部の情報と連動して動作するための通信機能を備えるものが多くなった。このように電化製品のネットワーク化の流れを受けて、現在では宅内の電化製品をコントローラと呼ばれる制御機器から制御することで、ユーザに快適な住環境を提供しながら、エネルギー消費量を抑制するスマートハウスと呼ばれる、宅内制御システムを構築するための研究開発が盛んになっている。環境問題への意識の高まりや、電力不足に対する懸念が、このようなエネルギー消費抑制を目的としたスマートハウスに対する研究開発を加速化させている。 Because of the advancement of digital network technology, communication devices can be realized at low cost and in small size, and today, various types of devices are connected to the network and operate. Many appliances installed in the home are equipped with a communication function for operating in conjunction with information outside the device rather than the device alone. In response to the trend of networking electrical appliances in this way, it is now smart to control energy consumption while providing a comfortable living environment for users by controlling home appliances from control devices called controllers. Research and development for building an in-home control system called a house has become popular. Increasing awareness of environmental issues and concerns about power shortages are accelerating R & D on smart houses aimed at reducing energy consumption.
　スマートハウスを実現するシステムでは、家電機器の情報を収集し、家電機器を制御するための専用コントローラを宅内に配置し、家電の制御をコントローラから一元的に制御する方法が一般的である。一方で、スマートフォンやタブレットの高性能化や普及により、コントローラ機能をスマートフォン等で動作させることも可能になっており、固定的に設置されるもの、暫定的に設置されるものを含め、宅内に複数のコントローラが存在するような環境が生まれている。ホームネットワークにおける複数のコントローラが共存する環境に関する検討は、従来からＡＶ（Audio Visual）機器のネットワークにおいて、各機器間の連携に関連する競合動作を制御するために、特許文献１に示されているような競合制御方式の検討が行われている。 In a system that realizes a smart house, it is common to collect information on home appliances, place a dedicated controller for controlling the home appliances in the house, and control the home appliances centrally from the controller. On the other hand, with the high performance and widespread use of smartphones and tablets, it is also possible to operate the controller function on smartphones, including those that are permanently installed and those that are provisionally installed. An environment where multiple controllers exist is born. A study on an environment in which a plurality of controllers in a home network coexist is shown in Patent Document 1 in order to control a competitive operation related to cooperation between devices in a network of AV (Audio Visual) devices. Such competition control methods are being studied.
　特許文献１では、コントローラから制御対象機器へ状態情報の報告要求を実施すると、他のコントローラから状態情報の報告要求を受け付けないようにする機能を実装し、コントローラ間の制御の競合を制御している。これは時間的に先に報告要求を送信したコントローラ以外からの制御を、制御対象機器側で制限することで、コントローラ間の制御に関する競合制御を実現している。 In Patent Document 1, when a status information report request from a controller to a control target device is implemented, a function is implemented to prevent the status information report request from being received from another controller, and control conflicts between controllers are controlled. Yes. This realizes competitive control related to control between controllers by restricting control from a device other than the controller that transmitted the report request earlier in time on the control target device side.
特開平０４－３６０４９６号公報Japanese Patent Laid-Open No. 04-36096
　特許文献１に示すように、従来の方式では制御対象機器側でコントローラからの制御を受け付けるかどうかの判断を行い、コントローラ間の競合制御を行っていた。これにより制御対象機器に対して先にアクセスしたコントローラが、機器に対する制御権を持つことができることにより、後からアクセスするコントローラからの制御を拒否し、コントローラ間の制御に対する競合を防止することができる。
　しかし、従来の方式では機器側で競合制御の機能を持つため、下記に示す通りいくつかの課題がある。もっとも大きな課題は、機器側に競合制御の機能を実装することが必要となり、機器コストが増大することにある。制御対象となる宅内機器は、コスト削減のため必要最低限なハードウェアにより実現されており、機能追加が機器のコストアップに直結する。単機能な宅内機器におけるハードウェアリソースの制約は厳しく、従来方式で宅内機器全てに競合制御機能を追加することは、システム全体として大きなコストアップにつながってしまう。また、機器側の機能により競合制御を可能とできるか不可能であるかが決まるため、複数のメーカーの様々な機器が接続される宅内のネットワークにおいては、システム全体で競合制御を行うことができないという課題がある。 As shown in Patent Document 1, in the conventional method, the control target device side determines whether to accept control from the controller, and performs competition control between controllers. As a result, the controller that previously accessed the control target device can have control authority over the device, so that control from the controller that is accessed later can be rejected and contention for control between the controllers can be prevented. .
However, since the conventional method has a competition control function on the device side, there are some problems as shown below. The biggest problem is that it is necessary to implement a competition control function on the device side, which increases the device cost. The in-home devices to be controlled are realized by the minimum hardware necessary for cost reduction, and the addition of functions directly leads to the cost increase of the devices. Hardware resources in a single-function home device are severely limited, and adding a contention control function to all home devices in the conventional method leads to a large cost increase for the entire system. In addition, since it is determined whether or not competitive control is possible depending on the function on the device side, in a home network to which various devices of multiple manufacturers are connected, competitive control cannot be performed in the entire system. There is a problem.
　本発明は、係る課題を解決するもので有り、ホームネットワークシステム全体において競合制御を行うことができる宅内機器制御装置を得ることを目的とする。 The present invention solves such a problem, and an object of the present invention is to provide a home device control apparatus capable of performing competition control in the entire home network system.

　本実施の形態では、コントローラ２およびコントローラ３の担当範囲である受け持ちエリアのコードは、「リビング」「キッチン」「その他」の３種類が定義されているものとする。また、リビング担当のコントローラはリビング家電であるエアコン７、ＴＶ８の制御に対して優先権を持ち、キッチン担当のコントローラは冷蔵庫４、換気扇５、ＩＨクッキングヒータ６の制御に対して優先権を持つ場合について説明を行う。コントローラ２はキッチン担当コントローラ、コントローラ３はリビング担当コントローラである。なお、受け持ちエリアコードの定義は、上述の種類の数や内容に限定されるものではない。 In this embodiment, it is assumed that three types of codes “living room”, “kitchen”, and “others” are defined as the codes of the service areas that are the assigned ranges of the controller 2 and the controller 3. In addition, the controller in charge of living has priority over the control of the air conditioner 7 and TV 8 that are living appliances, and the controller in charge of kitchen has priority over control of the refrigerator 4, the ventilation fan 5, and the IH cooking heater 6. Give an explanation. The controller 2 is a kitchen controller, and the controller 3 is a living controller. Note that the definition of the service area code is not limited to the number and contents of the types described above.
　コントローラ機能２０３は、ホームネットワーク１内に存在し、自装置が制御対象とする宅内機器を制御する。 The controller function 203 exists in the home network 1 and controls home devices that are controlled by the own device.
　図４はキッチン担当のコントローラであるコントローラ２の競合制御データベース２０５の設定状況を示しており、図５はリビング担当のコントローラであるコントローラ３の競合制御データベース２０５の設定状況を示している。エリアと対応機器の設定は、同一ネットワーク内のコントローラで統一されていることが必要である。このように、競合制御データベース２０５は、自装置がコントローラ機能２０３により制御を担当する担当範囲の情報を記憶している。 FIG. 4 shows the setting status of the conflict control database 205 of the controller 2 which is the controller in charge of kitchen, and FIG. 5 shows the setting status of the conflict control database 205 of the controller 3 which is the controller in charge of living. The area and compatible device settings must be unified by the controllers in the same network. As described above, the contention control database 205 stores information on a range in which the own device is in charge of control by the controller function 203.
　図６は本発明に関わるコントローラ２およびコントローラ３のそれぞれの競合制御機能２０４が取り扱う競合制御のための情報を示している。本実施の形態ではECHONET Lite（エコーネットライト）プロトコルで規定されたデータフォーマットを使い、各コントローラの競合制御機能２０４間で情報の伝達を行う場合を想定している。ただし、実際の適用では本フォーマットに基づくデータ以外のデータで情報伝達を行っても良い。 FIG. 6 shows information for contention control handled by the contention control functions 204 of the controller 2 and the controller 3 according to the present invention. In the present embodiment, it is assumed that information is transmitted between the competition control functions 204 of the controllers using a data format defined by the ECHONET Lite (Echonet Write) protocol. However, in actual application, information transmission may be performed using data other than data based on this format.
　競合制御機能２０４が取り扱うECHONET Liteプロトコルのフレーム（ECHONET Liteフレーム）９は、ECHONET Lite電文ヘッダ１（EHD1）、ECHONET Lite電文ヘッダ２（EHD2）、トランザクションＩＤ（TID）と、ECHONET Liteデータ（EDATA）で構成される。ECHONET Liteデータ９０１は、送信元ECHONET Liteオブジェクト指定（SEOJ）、相手先ECHONETC Liteオブジェクト指定（DEOJ）、ECHONET Liteサービス（ESV）、処理プロパティ数（OPC）と、複数のECHONET Liteプロパティ（EPC）、EDTのバイト数（PDC）、プロパティ値データ（EDT）から構成される。 The ECHONET Lite protocol frame (ECHONET Lite frame) 9 handled by the contention control function 204 includes an ECHONET Lite message header 1 (EHD1), an ECHONET Lite message header 2 (EHD2), a transaction ID (TID), and ECHONET Lite data (EDATA). Consists of. The ECHONET Lite data 901 includes a source ECHONET Lite object specification (SEOJ), a destination ECHONETC Lite object specification (DEOJ), an ECHONET Lite service (ESV), the number of processing properties (OPC), multiple ECHONET Lite properties (EPC), Consists of EDT byte count (PDC) and property value data (EDT).
　本実施の形態における競合制御には、ECHONET Liteフレームの送信元ECHONET Liteオブジェクト指定（SEOJ）９０２を利用する。送信元ECHONET Liteオブジェクト指定（SEOJ）９０２は、クラスグループコード、クラスコード、インスタンスコードから構成される。本情報を送信する機器はコントローラであるため、コントローラであることを示すために、クラスグループコードは0x05に設定し、クラスコードは0xFFを指定する。また、残りのインスタンスコードを受け持ちエリアコードとすることで、本データを送信するコントローラが自分で担当するエリアについて、このインスタンスコードを使って、他のコントローラに主張する。
　なお、ECHONET Liteプロトコルにおいて、クラスグループコード、クラスコード、インスタンスコードは他の目的に使われる目的で標準的には値が決められているが、そのうち現在リザーブとなっている値を本目的で使うことを想定している。このため、リザーブの中から値を定義している。上述の指定値は、これら値ではなくその他の値でも構わないが、ECHONET Liteプロトコルで現在利用目的が定義されているもの以外から選択することが望まれる。 The contention control in this embodiment uses the ECHONET Lite frame transmission source ECHONET Lite object designation (SEOJ) 902. The transmission source ECHONET Lite object specification (SEOJ) 902 includes a class group code, a class code, and an instance code. Since the device that transmits this information is a controller, the class group code is set to 0x05 and the class code is specified to be 0xFF to indicate that it is a controller. In addition, by taking the remaining instance code as the area code, the controller that transmits this data is in charge of the controller itself, and uses this instance code to insist on other controllers.
In the ECHONET Lite protocol, class group codes, class codes, and instance codes have standard values for other purposes, but the currently reserved values are used for this purpose. Assumes that. For this reason, values are defined from the reserve. The above specified values may be other values instead of these values, but it is desirable to select from those other than those currently defined for the purpose of use in the ECHONET Lite protocol.
　図７は本実施形態において、コントローラ２と、冷蔵庫４、換気扇５、ＩＨクッキングヒータ６、エアコン７が設置されている家に、後からコントローラ３とＴＶ８が設置されてきた場合の動作シーケンスについて示している。 FIG. 7 shows an operation sequence in the case where the controller 3 and the TV 8 are later installed in a house in which the controller 2, the refrigerator 4, the ventilation fan 5, the IH cooking heater 6, and the air conditioner 7 are installed. Yes.
　コントローラ２の競合制御機能２０４は、コントローラ２が起動されるか、コントローラ２がネットワークに接続されたタイミングで、通信機能２０２を介して、同一のネットワーク内に接続されている全ての機器に対して、プロパティ値読み出し１００１を送信する。コントローラ２はキッチン担当のコントローラであるため、このプロパティ値読み出し１００１は、図６に示した送信元ECHONETオブジェクト指定９０２のフィールドに、クラスグループコードに0x05、クラスコードに0xFF、インスタンスコードに「キッチン」が、それぞれ設定されている。 The contention control function 204 of the controller 2 is applied to all devices connected in the same network via the communication function 202 at the timing when the controller 2 is activated or the controller 2 is connected to the network. , Property value read 1001 is transmitted. Since the controller 2 is a controller in charge of the kitchen, this property value reading 1001 is “0x05” for the class group code, “0xFF” for the class code, and “kitchen” for the instance code in the field of the source ECHONET object designation 902 shown in FIG. Are set respectively.
　プロパティ値読み出し１００１を受信した各家電機器（冷蔵庫４、換気扇５、ＩＨクッキングヒータ６、エアコン７）は、それぞれの機器が対応する機能のECHONETオブジェクトのプロパティを設定したプロパティ値応答１００２～１００５を、コントローラ２に対して送信する。 Each home electric appliance (refrigerator 4, ventilation fan 5, IH cooking heater 6, air conditioner 7) that has received the property value read 1001 sends a property value response 1002 to 1005 in which the properties of the ECHONET object of the function corresponding to each device are set. 2 is transmitted.
　コントローラ２では、プロパティ値応答１００２～１００５を受信したことで、ネットワーク内に冷蔵庫４、換気扇５、ＩＨクッキングヒータ６、エアコン７が存在していることがわかる。 The controller 2 receives the property value responses 1002 to 1005, so that it can be seen that the refrigerator 4, the ventilation fan 5, the IH cooking heater 6 and the air conditioner 7 exist in the network.
　次にコントローラ３の競合制御機能２０４は、コントローラ３が起動されるか、コントローラ３がネットワークに接続されたタイミングで、同一のネットワーク内に接続されている全ての機器に対して、通信機能２０２を介して、プロパティ値読み出し１００６を送信する。コントローラ３はリビング担当のコントローラであるため、このプロパティ値読み出し１００６は、図６に示した送信元ECHONETオブジェクト指定のフィールドに、クラスグループコードに0x05、クラスコードに0xFF、インスタンスコードに「リビング」を示すコードが設定されている。 Next, the contention control function 204 of the controller 3 sets the communication function 202 to all devices connected in the same network at the timing when the controller 3 is activated or the controller 3 is connected to the network. Via this, a property value read 1006 is transmitted. Since the controller 3 is a living controller, this property value read 1006 sets the class group code 0x05, the class code 0xFF, and the instance code “living” in the field of the source ECHONET object designation shown in FIG. The code shown is set.
　プロパティ値読み出し１００６を受信した各家電機器（コントローラ２、冷蔵庫４、換気扇５、ＩＨクッキングヒータ６、エアコン７、ＴＶ８）は、それぞれの機器が対応する機能のECHONETオブジェクトのプロパティを設定したプロパティ値応答１００７～１０１２を、コントローラ２およびコントローラ３に対して送信する。 Each home appliance (controller 2, refrigerator 4, ventilation fan 5, IH cooking heater 6, air conditioner 7, TV 8) that has received the property value read 1006 has a property value response 1007 in which the properties of the ECHONET object of the function supported by each device are set. ˜1012 are transmitted to the controller 2 and the controller 3.
　この時、コントローラ３からのプロパティ値読み出し１００６を受信したコントローラ２は、受信したプロパティ値読み出し１００６の送信元ECHONETオブジェクト指定のフィールドに、クラスグループコードに0x05、クラスコードに0xFF、インスタンスコードに「リビング」を示すコードが設定されていることから、新しくネットワークに参入したコントローラ３がリビング担当のコントローラであることを知る。そしてコントローラ３に対してコントローラ２が送信するプロパティ値応答１０１２の送信元ECHONETオブジェクト指定のフィールドには、クラスグループコードに0x05、クラスコードに0xFF、インスタンスコードに「キッチン」を示すコードが設定されているため、コントローラ３はコントローラ２が、既にネットワークに存在しているキッチン担当のコントローラであることがわかる。 At this time, the controller 2 that has received the property value read 1006 from the controller 3 sets the class group code 0x05, the class code 0xFF, and the instance code “living room” in the field of the received property value read 1006 for the source ECHONET object designation. ”Is set, the controller 3 that has newly entered the network knows that it is the controller in charge of the living room. In the property value response 1012 sent from the controller 2 to the controller 3, the source ECHONET object designation field is set with a class group code of 0x05, a class code of 0xFF, and an instance code of “kitchen”. Therefore, the controller 3 knows that the controller 2 is a controller in charge of the kitchen that already exists in the network.
　この動作シーケンスによりコントローラ２、コントローラ３はお互いに、ネットワーク内に別のコントローラが存在していることと、相手の担当エリアを認識することができる。 This operation sequence allows the controller 2 and the controller 3 to recognize each other that another controller exists in the network and the partner's assigned area.
　図８はコントローラが他のコントローラからのプロパティ値読み出し１００６を受信した際の、処理フローを示している。プロパティ値読み出しを受信したコントローラは、コントローラ内の競合制御機能２０４で、この処理フローに基づきコントローラ間の制御対象の競合制御を行う。プロパティ値読み出し１００６を受信したコントローラは、最初に送信元コントローラの担当エリアを確認（１１０１）する処理で、送信元ECHONETオブジェクト指定９０２のインスタンスコードの情報から、送信元コントローラの担当エリアを確認する。 FIG. 8 shows a processing flow when the controller receives a property value read 1006 from another controller. The controller that has received the read property value performs contention control of the control target between controllers based on this processing flow by the contention control function 204 in the controller. The controller that has received the property value read 1006 first confirms the area in charge of the transmission source controller from the instance code information of the transmission source ECHONET object designation 902 in the process of confirming (1101) the area in charge of the transmission source controller.
　次に自装置と担当エリアが異なるかどうかを確認（１１０２）し、異なればプロパティ値読み出し１００６の送信元コントローラの担当エリアに対する家電機器を自装置の制御範囲から外す（１１０３）処理を行う。同一である場合には自装置より後に同一エリアを担当するコントローラが参入したとみなし、自分で管理している家電機器の制御を続けるため特に処理を行わない。その後送信元コントローラの情報と担当エリアの情報を保存（１１０４）し、プロパティ値応答を送信元に送信する（１１０５）。 Next, it is confirmed whether or not the own device and the assigned area are different (1102), and if different, the home appliance for the assigned controller area of the transmission source controller of property value reading 1006 is removed from the control range of the own device (1103). If they are the same, it is considered that a controller in charge of the same area has entered after the device itself, and no particular processing is performed in order to continue control of home appliances managed by the device itself. Thereafter, the information on the transmission source controller and the information on the area in charge are stored (1104), and the property value response is transmitted to the transmission source (1105).
　これにより新たに担当エリアが異なるコントローラがネットワークに参入した際に、既に稼働しているコントローラが新しく参入したコントローラの担当範囲を認識し、制御対象機器を新しく参入したコントローラに譲り渡すことが可能になる。また１１０４で保存した送信元コントローラの情報と担当エリアの情報から、今後ネットワークに参入してくる家電機器に対して、自装置が制御するか、他のコントローラに制御権を渡すために制御範囲から外すかを決定できるようになる。 As a result, when a controller with a different assigned area enters the network, it becomes possible for the already operating controller to recognize the assigned range of the newly entered controller and transfer the control target device to the newly entered controller. . In addition, from the information of the transmission source controller and the information of the area in charge stored in 1104, the home apparatus controls the home appliances that will enter the network in the future, or from the control range in order to pass the control right to other controllers. It will be possible to decide whether to remove.
　図９はコントローラが自装置で送信したプロパティ値読み出し１００６に対する他のコントローラからのプロパティ値応答１０１２を受信した場合の処理の内容を示した状態遷移図である。状態遷移の横軸は、プロパティ値応答を受信前の状態を示しており、縦軸は受信したプロパティ値応答の情報を示している。 FIG. 9 is a state transition diagram showing the contents of processing when the controller receives a property value response 1012 from another controller in response to the property value read 1006 transmitted by the controller. The horizontal axis of the state transition indicates the state before receiving the property value response, and the vertical axis indicates the received property value response information.
　プロパティ値応答を受信する前の状態としては、既存コントローラからの応答を未受信（１２０１）の状態、既存コントローラからの応答を受信済みで自装置と同一エリアを担当するコントローラが存在する（１２０２）状態、既存コントローラからの応答を受信済みで自装置と異なるエリアを担当するコントローラが存在する（１２０３）状態、がある。 As a state before receiving a property value response, there is a state in which a response from an existing controller has not been received (1201), and a controller that has received a response from an existing controller and is responsible for the same area as the own device (1202). There is a state in which there is a controller that has received a response from an existing controller and is in charge of an area different from the own device (1203).
　受信したプロパティ値応答の情報としては、受信した応答がコントローラからで、かつ自装置と同一エリア担当のコントローラである（１２０４）場合、受信した応答がコントローラからで、かつ自装置と異なるエリア担当のコントローラである（１２０５）場合、および、受信した応答がコントローラ以外からである（１２０６）場合、がある。 As the received property value response information, if the received response is from the controller and is the controller in charge of the same area as the own device (1204), the received response is from the controller and is in charge of an area in charge different from the own device. There is a case of being a controller (1205) and a case where the received response is from other than the controller (1206).
　コントローラの競合制御機能２０４は、既存コントローラからの応答を未受信（１２０１）の場合、自装置と同一エリアのコントローラから応答を受信（１２０４）した時には、受信したコントローラ情報と担当エリア情報を保存し、競合制御データベース２０５で管理している家電機器を自装置の制御範囲から外す（１２０７）処理を行う。
　既存コントローラからの応答を未受信（１２０１）の場合、自装置と異なるエリアのコントローラから応答を受信（１２０５）した時には、受信したコントローラ情報と担当エリア情報を競合制御データベース２０５に保存する（１２０８）処理を行う。
　既存コントローラからの応答を未受信（１２０１）の場合、コントローラ以外から応答を受信（１２０６）した時には、家電機器の情報を自装置の制御範囲として競合制御データベース２０５に保存する（１２０９）処理を行う。 If the controller's contention control function 204 has not received a response from an existing controller (1201), it receives the response from a controller in the same area as its own device (1204), and stores the received controller information and assigned area information. Then, the home appliance managed by the competition control database 205 is removed from the control range of the own device (1207).
If the response from the existing controller has not been received (1201), when the response is received from the controller in an area different from the own device (1205), the received controller information and assigned area information are stored in the contention control database 205 (1208). Process.
When the response from the existing controller is not received (1201), when the response is received from other than the controller (1206), the home appliance information is stored in the competition control database 205 as the control range of the own device (1209). .
　コントローラの競合制御機能２０４は、既存コントローラからの応答を受信済みで、そのコントローラが自装置と同一エリアを担当するコントローラである（１２０２）場合、自装置と同一エリアのコントローラから応答を受信（１２０４）した時、あるいは自装置と異なるエリアのコントローラから応答を受信（１２０５）した時には、受信したコントローラ情報と担当エリア情報を競合制御データベース２０５に保存する（１２１０）処理を行う。
　既存コントローラからの応答を受信済みで、そのコントローラが自装置と同一エリアを担当するコントローラである（１２０２）場合、受信した応答がコントローラ以外から（１２０６）である時には、家電機器の情報を自装置の制御範囲から外した状態で競合制御データベース２０５に保存する（１２１１）処理を行う。 If the controller's contention control function 204 has already received a response from the existing controller and the controller is the controller in charge of the same area as that of its own device (1202), it receives a response from the controller in the same area as that of its own device (1204) ), Or when a response is received from a controller in an area different from that of the own device (1205), the received controller information and assigned area information are stored in the conflict control database 205 (1210).
If the response from the existing controller has been received and the controller is the controller in charge of the same area as the own device (1202), when the received response is from other than the controller (1206), the home appliance information is sent to the own device. (1211) is stored in the contention control database 205 in a state outside the control range.
　コントローラの競合制御機能２０４は、既存コントローラからの応答を受信済みで、そのコントローラが自装置と異なるエリアを担当するコントローラである（１２０３）場合、自装置と同一エリアのコントローラから応答を受信（１２０４）した時には、受信したコントローラ情報と担当エリア情報を保存し、競合制御データベース２０５で管理している家電機器を自装置の制御範囲から外す（１２１２）処理を行う。
　既存コントローラからの応答を受信済みで、そのコントローラが自装置と異なるエリアを担当するコントローラである（１２０３）場合、自装置と異なるエリアのコントローラから応答を受信（１２０５）した時には、受信したコントローラ情報と担当エリア情報を競合制御データベース２０５に保存（１２１３）する処理を行う。
　既存コントローラからの応答を受信済みで、そのコントローラが自装置と異なるエリアを担当するコントローラである（１２０３）場合、受信した応答がコントローラ以外から（１２０６）の時には、家電機器の情報を自装置の制御範囲として競合制御データベース２０５に保存する（１２１４）処理を行う。 When the controller's contention control function 204 has received a response from the existing controller and the controller is a controller in charge of an area different from the own device (1203), the controller's conflict control function 204 receives a response from the controller in the same area as the own device (1204). ), The received controller information and assigned area information are stored, and the home appliance managed by the contention control database 205 is removed from the control range of its own device (1212).
When a response from an existing controller has been received and the controller is a controller in charge of an area different from the own device (1203), when a response is received from a controller in an area different from the own device (1205), the received controller information And the processing for saving the assigned area information in the contention control database 205 (1213).
If the response from the existing controller has been received and the controller is a controller in charge of an area different from that of the own device (1203), when the received response is from other than the controller (1206), the home appliance information is obtained from the own device. A process of storing in the contention control database 205 as a control range (1214) is performed.
　以上のように、コントローラの競合制御機能２０４は、競合制御データベース２０５に記憶された情報に基づき、ホームネットワーク１内に存在する他のコントローラとの間で、制御対象の宅内機器の範囲を調停するために、担当範囲に関する情報を送受し、ホームネットワーク１内に存在する各宅内機器に対し、自装置が制御対象とするか否かの判断を行う。 As described above, the contention control function 204 of the controller arbitrates the range of home devices to be controlled with other controllers existing in the home network 1 based on the information stored in the contention control database 205. For this purpose, information on the assigned range is transmitted and received, and it is determined whether or not the own device is a control target for each in-home device existing in the home network 1.
　これらの処理により、先にホームネットワーク１に参入しているコントローラ２と、後からホームネットワーク１に参入するコントローラ３間で、自装置の担当エリア情報に基づき、制御対象機器の競合を回避することができるようになる。 Through these processes, the conflict between controlled devices between the controller 2 that has entered the home network 1 and the controller 3 that has entered the home network 1 later is determined based on the area information of its own device. Will be able to.
　以上のように、本発明の実施形態１における宅内機器制御装置では、ホームネットワークに参入している複数のコントローラ間で制御対象機器の競合を回避することができる効果が得られる。 As described above, in the in-home device control apparatus according to Embodiment 1 of the present invention, there is an effect that it is possible to avoid contention of control target devices among a plurality of controllers that have entered the home network.
実施の形態２．
　実施の形態２において、宅内機器制御装置を用いたシステム全体の構成図、宅内機器制御装置であるコントローラのハードウェア構成図、コントローラの機能ブロック構成図は、それぞれ、実施の形態１に示した、図１、図２、図３、と同一である Embodiment 2. FIG.
In the second embodiment, the configuration diagram of the entire system using the home appliance control device, the hardware configuration diagram of the controller that is the home appliance control device, and the functional block configuration diagram of the controller are shown in the first embodiment, respectively. Same as FIG. 1, FIG. 2, FIG.
　図１０は本発明の実施の形態２における、キッチン担当のコントローラであるコントローラ２の競合制御データベース２０５の設定状況を示しており、図１１はリビング担当のコントローラであるコントローラ３の競合制御データベース２０５の設定状況を示している。エリアと対応機器の設定は、同一ネットワーク内のコントローラ間で統一されているものとする。実施の形態１で定義された情報に加えて、新たに優先度情報がデータベース内に定義されている。このように、競合制御データベース２０５は、自装置がコントローラ機能２０３により制御を担当する担当範囲の情報に加えて、自装置および他の制御装置の間の優先度の情報を記憶している。 FIG. 10 shows the setting status of the competition control database 205 of the controller 2 which is the controller in charge of kitchen in Embodiment 2 of the present invention, and FIG. 11 shows the setting of the competition control database 205 of the controller 3 which is the controller in charge of living. The setting status is shown. It is assumed that the setting of the area and the corresponding device is unified between controllers in the same network. In addition to the information defined in the first embodiment, priority information is newly defined in the database. As described above, the contention control database 205 stores information on priority between the own device and another control device in addition to information on a range in which the own device is in charge of control by the controller function 203.
図１２は本発明の実施の形態２に関わるコントローラ２およびコントローラ３のそれぞれの競合制御機能２０４が取り扱う競合制御のための情報を示している。本実施の形態ではECHONET Liteプロトコルで規定されたデータフォーマットを使い、各コントローラの競合制御機能２０４間で情報の伝達を行う場合を想定している。なお、実際の適用では本フォーマットに基づくデータ以外のデータで情報伝達を行っても構わない。 FIG. 12 shows information for contention control handled by the contention control function 204 of each of the controller 2 and the controller 3 according to the second embodiment of the present invention. In this embodiment, it is assumed that information is transmitted between the contention control functions 204 of each controller using a data format defined by the ECHONET Lite protocol. In actual application, information transmission may be performed using data other than data based on this format.
　競合制御機能２０４が取り扱うECHONET Liteプロトコルのフレーム（ECHONET Liteフレーム）９は、ECHONET Lite電文ヘッダ１（EHD1）、ECHONET Lite電文ヘッダ２（EHD2）、トランザクションＩＤ（TID）と、ECHONET Liteデータ（EDATA）で構成される。ECHONET Liteデータ９０１は、送信元ECHONET Liteオブジェクト指定（SEOJ）、相手先ECHONETC Liteオブジェクト指定（DEOJ）、ECHONET Liteサービス（ESV）、処理プロパティ数（OPC）と、複数のECHONET Liteプロパティ（EPC）、EDTのバイト数（PDC）、プロパティ値データ（EDT）から構成される。 The ECHONET Lite protocol frame (ECHONET Lite frame) 9 handled by the contention control function 204 includes an ECHONET Lite message header 1 (EHD1), an ECHONET Lite message header 2 (EHD2), a transaction ID (TID), and ECHONET Lite data (EDATA). Consists of. The ECHONET Lite data 901 includes a source ECHONET Lite object specification (SEOJ), a destination ECHONETC Lite object specification (DEOJ), an ECHONET Lite service (ESV), the number of processing properties (OPC), multiple ECHONET Lite properties (EPC), Consists of EDT byte count (PDC) and property value data (EDT).
　本実施の形態における競合制御には、ECHONET Liteフレームの送信元ECHONET Liteオブジェクト指定（SEOJ）９０２を利用する。送信元ECHONET Liteオブジェクト指定（SEOJ）９０２は、クラスグループコード、クラスコード、インスタンスコードから構成される。本情報を送信する機器はコントローラであるため、コントローラであることを示すために、クラスグループコードは0x05に設定し、クラスコードは0xFFを指定する。残りのインスタンスコードを受け持ちエリアコードと優先度情報に基づき定義することで、本データを送信するコントローラが自分で担当するエリアと自装置の優先度について、このインスタンスコードを使って、他のコントローラに主張することが可能になる。 For the contention control in this embodiment, the source ECHONET Lite object specification (SEOJ) 902 of the ECHONET Lite frame is used. The transmission source ECHONET Lite object specification (SEOJ) 902 includes a class group code, a class code, and an instance code. Since the device that transmits this information is a controller, the class group code is set to 0x05 and the class code is specified to be 0xFF to indicate that it is a controller. By defining the remaining instance codes based on the area code and priority information, the controller sending this data is responsible for the area that it is responsible for and the priority of its own device. It becomes possible to insist.
　図１３はコントローラが他のコントローラからのプロパティ値読み出し１００６を受信した際の、処理フローを示している。プロパティ値読み出しを受信したコントローラは、コントローラ内の競合制御機能２０４で、この処理フローに基づきコントローラ間の制御対象の競合制御を行う。プロパティ値読み出しを受信したコントローラは、最初に送信元コントローラの担当エリアおよび優先度を確認（１５０１）する処理で、送信元ECHONETオブジェクト指定９０２のインスタンスコードの情報から、送信元コントローラの担当エリアを確認する。 FIG. 13 shows a processing flow when the controller receives a property value read 1006 from another controller. The controller that has received the read property value performs contention control of the control target between controllers based on this processing flow by the contention control function 204 in the controller. The controller that received the property value read first checks the area in charge of the transmission source controller from the instance code information of the transmission source ECHONET object specification 902 in the process of checking the area and priority of the transmission source controller (1501). To do.
　次に自装置と担当エリアが異なるかどうかと、自装置との優先度を確認（１５０２）し、エリアが異なるか、優先度が自装置より高い場合には、プロパティ値読み出しの送信元コントローラの担当エリアに対する家電機器を自装置の制御範囲から外す（１５０３）処理を行う。同一である場合には自装置より後に同一エリアを担当する優先度の低いコントローラが参入したとみなし、自分で管理している家電機器の制御を続けるため特に処理を行わない。その後送信元コントローラの情報と担当エリアの情報を保存（１５０４）し、プロパティ値応答を送信元に送信（１５０５）する。 Next, whether or not the own device and the assigned area are different and the priority with the own device are confirmed (1502). If the area is different or the priority is higher than that of the own device, the property value reading source controller The home appliance for the assigned area is removed from the control range of its own device (1503). If they are the same, it is considered that a low-priority controller in charge of the same area has entered after the device itself, and no particular processing is performed in order to continue control of home appliances managed by the device itself. Thereafter, the information of the transmission source controller and the information of the area in charge are saved (1504), and the property value response is transmitted to the transmission source (1505).
　以上のように、コントローラの競合制御機能２０４は、ホームネットワーク１内に存在する他の制御装置との間で、制御対象の宅内機器の範囲を調停するために、担当範囲に関する情報と優先度の情報を送受し、ホームネットワーク１内に存在する各宅内機器に対し、自装置が制御対象とするか否かの判断を行う。 As described above, the contention control function 204 of the controller determines the information on the assigned range and the priority in order to mediate the range of the home device to be controlled with other control devices existing in the home network 1. Information is transmitted and received, and it is determined whether or not the own device is a control target for each home device in the home network 1.
　これにより新たに担当エリアが異なるコントローラがネットワークに参入した際に、既に稼働しているコントローラが新しく参入したコントローラの担当範囲と優先度を認識し、制御対象機器を新しく参入したコントローラに譲り渡すことが可能になる。 As a result, when a controller with a different assigned area enters the network, the already operating controller recognizes the assigned scope and priority of the newly entered controller, and transfers the control target device to the newly entered controller. It becomes possible.
　また１５０４で保存した送信元コントローラの情報と担当エリアの情報から、今後ネットワークに参入してくる家電機器に対して、自装置が制御するか、他のコントローラに制御権を渡すために制御範囲から外すかを決定できるようになる。
　同様にコントローラ３においてプロパティ値応答を受信した際にも、優先度の情報を受け取ることが可能になるため、新規参入したコントローラと先にネットワークに存在したコントローラの双方で優先度に基づいた競合制御を実現することができるようになる。 In addition, from the source controller information and the information on the area in charge stored in 1504, the home apparatus controls the home appliances that will enter the network in the future, or from the control range in order to pass control rights to other controllers. It will be possible to decide whether to remove.
Similarly, when the controller 3 receives a property value response, it becomes possible to receive priority information. Therefore, both the newly entered controller and the controller that previously existed in the network control contention based on the priority. Can be realized.
　以上のように、本発明の実施形態２における宅内機器制御装置では、ホームネットワークに参入している複数のコントローラ間で制御対象機器の競合を回避することができるとともに、複数のコントローラ間で優先度に基づいた競合制御を実現することができる効果が得られる。 As described above, in the in-home device control apparatus according to Embodiment 2 of the present invention, it is possible to avoid contention of control target devices among a plurality of controllers that have entered the home network, and priority among a plurality of controllers. The effect that the competition control based on the above can be realized is obtained.
