Description

【0001】
【発明の属する技術分野】
本発明は、電波を用いてデータ通信を行う通信装置であって、特に家庭においてホームネットワークを構成する通信装置に関するものである。
【0002】
【従来の技術】
近年、エアコンや冷蔵庫などの白物家電機器や侵入センサー等のセキュリティ機器と家庭内に設置されたホームコントローラとを無線で接続し、前記ホームコントローラを介して携帯電話と接続し、家の外よりエアコン等の機器をコントロールしたり、家の中のセキュリティ情報を携帯電話を介して外出中の家人に報知したりする家庭内ネットワークシステムが開発されてきている。日本においては上記家庭内ネットワークシステムの業界標準としてエコーネット規格が制定されている。
【0003】
上記エコーネット規格を用いた無線ネットワークシステムにおいて、それぞれネットワークを構成する機器は二つの識別符号を有している。一つは各家庭毎に割り振られ、一つの家庭に所属する機器すべてに共通な識別符号である無線システム識別符号である。そして他の一つは機器毎に異なる符号を割り振られる機器識別符号である。二つの機器の間で通信を行わせるためには無線システム識別符号が一致していることと、通信相手の機器識別符号を指定して送信する必要がある。そして上記無線システム識別符号と機器識別符号は上記ホームコントローラから割り振られる。
【0004】
図2に従来の家庭内ネットワークシステムを構成するホームコントローラに内蔵される親無線機とエアコン等の端末機器に内蔵される子無線機の構成を示す。図3には親無線機と子無線機の間で行われる識別符号の割り当て手順を示す。図2及び図3を参照しながら従来例について説明する。
【0005】
図2において、1は親無線機のアンテナ、2は無線通信手段、5は制御手段、6はスイッチ、7はホームコントローラ本体(図示せず)との通信端子、そして8が親無線機である。9は子無線機のアンテナ、10は無線通信手段、13は制御手段、14はスイッチ、15はエアコン等の端末機器(図示せず)との通信端子、16は子無線機である。子無線機16が親無線機8に対して識別符号要求電波を送信する場合、所定の出力10dBmで送信する。親無線機8についても子無線機16と同様に、あらかじめ定められている所定の出力10dBmで送信する。
【0006】
さて上記親無線機8と子無線機16との間の識別符号割り当て手順について図3を参照しながら説明する。
【0007】
ステップ1(ST1):親無線機8のスイッチ6をONする。すると親無線機8は登録状態に遷移し、登録状態専用の無線チャンネルで子無線機16からの電波を待ちうける。
【0008】
ステップ2(ST2):子無線機16のスイッチ14をONする。すると子無線機16は登録状態に遷移する。
【0009】
ステップ3(ST3):子無線機16は登録状態に遷移すると、登録状態専用の無線チャンネルで識別符号付与要求信号を無線送信する。この時子無線機16が仮に割り振った子無線機16の仮機器識別符号を上記無線送信する信号に付加して送信する。
【0010】
ステップ4(ST4):親無線機8は上記識別符号付与要求信号を受信すると、親無線機8が管理する子無線機群の機器識別符号テーブルを参照しまだ付与していない機器識別符号と無線システム識別符号を上記仮機器識別符号の機器宛に、識別符号割り当て信号に乗せて送る。
【0011】
ステップ5(ST5):子無線機16は上記識別符号割り当て信号を受信すると、親無線機8より割り当てられた無線システム識別符号及び機器識別符号を記憶し以後自機の識別符号として使用する。そして親無線機8に対して応答信号を送信し、登録処理を完了し通常動作状態に遷移する。
【0012】
ステップ6(ST6):親無線機8は上記応答信号を受信すると、登録処理を完了し通常動作状態に遷移する。
【0013】
【発明が解決しようとする課題】
上記登録動作において、たまたま隣の家の親無線機も登録状態に遷移していた場合、子無線機10から送信される識別符号付与要求信号(ステップ3)が隣の家の親無線機でも検出され隣の親無線機が識別符号割り当て信号を送信し誤って子無線機10が隣の家の識別符号割り当て信号を受信してしまう、という課題があった。

【0020】
本発明の請求項5にかかる通信装置は、子無線機が、登録状態に遷移すると親無線機に識別符号付与の要求信号を送信し、親無線機は前記子無線機からの前記要求信号を受信すると子無線機に対して未付与の識別符号を割り当て、前記割り当てた識別符号を前記子無線機を指定して無線送信し、前記子無線機は前記無線送信の信号を受信すると応答信号を送信した後、前記登録状態から通常状態に遷移する構成であることを特徴としたものである。そして、隣の家の親無線機が登録状態になっていたとしても、誤って隣の家の親無線機から識別符号を付与されることはない。

【0024】
【実施例】
以下、本発明の実施例について図面を用いて説明する。
【0025】
(実施例1)
図1は本発明の実施例1の通信装置を示すブロック図である。従来例と同一の機能ブロックには同一の番号を付与している。
【0026】
図1において、1は親無線機のアンテナ、2は無線通信手段、101は送信出力切替手段、105は制御手段、6はスイッチ、7はホームコントローラ本体(図示せず)との通信端子、そして8が親無線機である。9は子無線機のアンテナ、10は無線通信手段、102は送信出力切替手段、113は制御手段、14はスイッチ、15はエアコン等の端末機器(図示せず)との通信端子、16は子無線機である。
【0027】
子無線機16が親無線機8に電波を送信する場合、登録状態の場合と通常動作状態の場合で制御手段105の制御により送信出力を切り換える。そして送信出力切替手段は通常動作状態の場合の送信出力に比べ登録状態の場合の送信出力を低く設定されている。従って登録状態の時には通常動作状態の時に比べ弱い電波が送信されることとなる。よって親無線機8と子無線機16との間で登録状態になったとき、たまたま隣の家の親無線機が登録状態になっていたとしても、一般に隣の家の親無線機に到達する子無線機16の電波の強さは弱いところに登録状態においてはさらに弱くなるため隣の家の親無線機が子無線機16の登録時の電波を受信することはない。すなわち、従来例図3において隣の家の親無線機が仮に登録状態へ遷移されていても(ST1)、無線子機16からの識別符号付与要求(ST3)を受け付けることができないので隣の家との登録シーケンスが完了することはない。
【0028】
次に隣の家の子無線機が本発明の機能、すなわち登録状態の時と通常動作状態の時とで送信出力を切り換える機能を有していない場合、すなわち従来例図3において隣の家の子無線機が仮に登録状態へ遷移され(ST2)無線親機8において識別符号付与要求(ST3)を受け付けてしまった場合について説明する。この場合、親無線機8は隣の家の子無線機16が送信する識別符号付与要求信号を受信(ST3)し、前記親無線機8は識別符号割り当て信号を通常動作状態の時に比べ低い送信出力で送信する(ST4)。したがって隣の家の子無線機16では上記親無線機8からの識別符号割り当て信号(ST4)を受信できない。そのため隣の家の子無線機16は応答信号の送信(ST5)を行わず、隣の家との登録シーケンスが完了することはない。よって隣の家の子無線機に誤って識別符号を付与することはない。
【0029】
次に登録状態に遷移させる別の方法について説明する。通信端子7或いは通信端子15を用いてホームコントローラ本体或いはエアコン等の端末機器から電文を用いて親無線機8或いは子無線機16を登録状態に遷移させることができる。さらに別の方法として子無線機16の電源がONした時、子無線機16は無線システム識別符号及び機器識別符号が未設定かどうかを内部チェックし、既に識別符号が設定されていれば通常動作状態に移行し、識別符号が未設定であれば登録状態に遷移するように構成することができる。
【0030】
なお、端末機器がエアコンのように設置後動かすことのできない機器の場合は、ホームコントローラ側、すなわち親無線機側をエアコンの近くに持っていき登録手順を実行する。しかし侵入センサーや人感センサー等のセキュリティ機器は電池で駆動され簡単に移動可能なため、親無線機の近くに端末機器すなわち子無線機を持っていき登録手順を実行する。
【0031】
【発明の効果】
以上説明したように本発明の通信装置を用いることにより、親無線機と子無線機との間で識別符号の登録手順を実行するときに、たまたま隣の家の親無線機或いは子無線機が登録状態になっていたとしても、誤って隣の家の親無線機から子無線機が識別符号を取得或いは隣の家の子無線機に親無線機が識別符号を付与することはない。従って信頼性の高い識別符号登録手順を実行できる。

Description of the Related Art A home network system has been developed which controls devices such as an air conditioner, and notifies home security personnel who are out of the house via a mobile phone. In Japan, the Echonet standard has been established as an industry standard for the home network system.
[0003]
In the wireless network system using the Echonet standard, each device constituting the network has two identification codes. One is a wireless system identification code, which is allocated to each household and is an identification code common to all devices belonging to one household. The other is a device identification code that is assigned a different code for each device. In order to cause communication between the two devices, it is necessary to make sure that the wireless system identification codes match, and to specify and transmit the device identification code of the communication partner. The wireless system identification code and the device identification code are assigned by the home controller.
[0004]
FIG. 2 shows a configuration of a parent wireless device incorporated in a home controller constituting a conventional home network system and a configuration of a child wireless device incorporated in a terminal device such as an air conditioner. FIG. 3 shows a procedure of assigning an identification code performed between the master wireless device and the slave wireless device. A conventional example will be described with reference to FIGS.
[0005]
In FIG. 2, reference numeral 1 denotes an antenna of a master radio, 2 denotes wireless communication means, 5 denotes control means, 6 denotes a switch, 7 denotes a communication terminal with a home controller main body (not shown), and 8 denotes a master radio. . Reference numeral 9 denotes an antenna of the slave radio, 10 denotes wireless communication means, 13 denotes control means, 14 denotes a switch, 15 denotes a communication terminal with a terminal device (not shown) such as an air conditioner, and 16 denotes a slave radio. When the slave radio device 16 transmits the identification code request radio wave to the master radio device 8, the radio signal is transmitted at a predetermined output of 10 dBm. Similarly to the child wireless device 16, the master wireless device 8 transmits the signal with a predetermined output of 10 dBm.
[0006]
Now, a procedure for assigning an identification code between the parent wireless device 8 and the child wireless device 16 will be described with reference to FIG.
[0007]
Step 1 (ST1): The switch 6 of the master wireless device 8 is turned on. Then, the parent wireless device 8 transitions to the registered state, and waits for radio waves from the child wireless device 16 on the wireless channel dedicated to the registered state.
[0008]
Step 2 (ST2): The switch 14 of the slave radio 16 is turned on. Then, the child wireless device 16 transits to the registration state.
[0009]
Step 3 (ST3): Upon transition to the registration state, the slave radio device 16 wirelessly transmits an identification code assignment request signal on a wireless channel dedicated to the registration state. At this time, the child wireless device 16 adds the temporary device identification code of the child wireless device 16 provisionally allocated to the signal to be wirelessly transmitted, and transmits the signal.
[0010]
Step 4 (ST4): Upon receiving the identification code assignment request signal, the parent wireless device 8 refers to the device identification code table of the group of child wireless devices managed by the parent wireless device 8 and communicates with the device identification code that has not been assigned yet. The system identification code is sent to the device of the temporary device identification code in an identification code assignment signal.
[0011]
Step 5 (ST5): Upon receiving the identification code assignment signal, the child wireless device 16 stores the wireless system identification code and the device identification code assigned by the parent wireless device 8, and thereafter uses them as identification codes of its own device. Then, a response signal is transmitted to the parent wireless device 8 to complete the registration processing and transit to the normal operation state.
[0012]
Step 6 (ST6): Upon receiving the response signal, the master wireless device 8 completes the registration process and transitions to the normal operation state.
[0013]
[Problems to be solved by the invention]
In the above-described registration operation, when the parent wireless device of the next house happens to be in the registration state, the identification code assignment request signal (step 3) transmitted from the child wireless device 10 is detected by the parent wireless device of the next house. Then, there is a problem that an adjacent parent wireless device transmits an identification code assignment signal and the child wireless device 10 erroneously receives an identification code assignment signal of an adjacent house.
[0014]

[0024]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0025]
(Example 1)
FIG. 1 is a block diagram illustrating a communication device according to a first embodiment of the present invention. The same numbers are assigned to the same functional blocks as in the conventional example.
[0026]
In FIG. 1, reference numeral 1 denotes an antenna of a master radio, 2 denotes wireless communication means, 101 denotes transmission output switching means, 105 denotes control means, 6 denotes a switch, 7 denotes a communication terminal with a home controller main body (not shown), and Reference numeral 8 denotes a parent wireless device. Reference numeral 9 denotes an antenna of a child wireless device, 10 denotes wireless communication means, 102 denotes transmission output switching means, 113 denotes control means, 14 denotes a switch, 15 denotes a communication terminal with a terminal device (not shown) such as an air conditioner, and 16 denotes a child terminal. It is a radio.
[0027]
When the slave radio device 16 transmits a radio wave to the master radio device 8, the transmission output is switched under the control of the control means 105 in the case of the registration state and the case of the normal operation state. The transmission output switching means is set so that the transmission output in the registered state is lower than the transmission output in the normal operation state. Therefore, a weaker radio wave is transmitted in the registration state than in the normal operation state. Therefore, when the registered state is established between the parent wireless device 8 and the child wireless device 16, even if the parent wireless device of the next house happens to be in the registered state, it generally reaches the parent wireless device of the next house. Since the strength of the radio wave of the slave radio 16 is weaker in the registered state at a weak place, the master radio of the next house does not receive the radio wave at the time of registration of the slave radio 16. That is, in FIG. 3 of the related art, even if the parent wireless device of the adjacent house has transitioned to the registration state (ST1), it cannot receive the identification code assignment request (ST3) from the wireless slave device 16, so the adjacent house is not received. The registration sequence with is not completed.
[0028]
Next, when the child wireless device of the next house does not have the function of the present invention, that is, the function of switching the transmission output between the registered state and the normal operation state, that is, the child wireless device of the next house in FIG. A case will be described in which a transition is made to the registration state (ST2), and an identification code assignment request (ST3) is received by the wireless master device 8. In this case, the parent wireless device 8 receives the identification code assignment request signal transmitted by the child wireless device 16 of the adjacent house (ST3), and the parent wireless device 8 transmits the identification code assignment signal with a lower transmission output than in the normal operation state. Transmit (ST4). Therefore, the child wireless device 16 of the next house cannot receive the identification code assignment signal (ST4) from the parent wireless device 8. Therefore, the child wireless device 16 of the next house does not transmit the response signal (ST5), and the registration sequence with the next house is not completed. Therefore, the identification code is not erroneously given to the child wireless device of the next house.
[0029]
Next, another method for transitioning to the registration state will be described. Using the communication terminal 7 or the communication terminal 15, the parent wireless device 8 or the child wireless device 16 can be transitioned to the registration state from a terminal device such as a home controller main body or an air conditioner using a message. As another method, when the power of the slave radio device 16 is turned on, the slave radio device 16 internally checks whether the wireless system identification code and the device identification code are not set, and if the identification code is already set, the normal operation is performed. It can be configured to shift to a registered state if the identification code has not been set.
[0030]
If the terminal device is a device that cannot be moved after installation, such as an air conditioner, the registration procedure is performed by bringing the home controller side, that is, the parent wireless device side, near the air conditioner. However, since security devices such as an intrusion sensor and a human sensor are driven by a battery and can be easily moved, a terminal device, that is, a child wireless device is brought near the parent wireless device to execute a registration procedure.
[0031]
【The invention's effect】
As described above, by using the communication device of the present invention, when executing the registration procedure of the identification code between the parent wireless device and the child wireless device, the parent wireless device or the child wireless device of the next house happens to be Even in the registered state, the child wireless device does not erroneously acquire the identification code from the parent wireless device of the next house, or the parent wireless device does not give the identification code to the child wireless device of the next house. Therefore, a highly reliable identification code registration procedure can be executed.
