Description

推定装置および無線システムEstimation apparatus and radio system
　本発明は、無線メッシュネットワークを構成する無線親機に接続された推定装置および推定装置を備えた無線システムに関する。 The present invention relates to an estimation device connected to a wireless master device configuring a wireless mesh network and a wireless system including the estimation device.
　既存のネットワークインフラを用いることなく、無線通信機器間で通信を可能にする無線メッシュ（アドホック）ネットワークにおいて、数々のルーティングプロトコル（アドホックルーティングプロトコル）が提案されている（非特許文献１、２参照）。非特許文献１および２に示された無線メッシュ（アドホック）ネットワークを用いた無線システムは、安定してシステムを構築している否か、安定して運用可能か否かを判定するために、各無線端末同士の接続関係（トポロジ）の管理が必要であった。そこで、非特許文献１に示された無線システムは、全ての無線端末が他の無線端末に定期的に送信しあうことで、全無線端末が接続関係の情報の共有を実現している。 Numerous routing protocols (ad hoc routing protocols) have been proposed in wireless mesh (ad hoc) networks that enable communication between wireless communication devices without using existing network infrastructure (see Non-Patent Documents 1 and 2). . In order to determine whether the wireless system using the wireless mesh (ad hoc) network shown in Non-Patent Documents 1 and 2 is building a system stably and whether it can be stably operated, Management of the connection relationship (topology) between wireless terminals was necessary. Therefore, the wireless system disclosed in Non-Patent Document 1 realizes sharing of connection-related information by all wireless terminals by periodically transmitting to other wireless terminals.
　また、非特許文献１に示された無線システムにおいて、最終的に接続関係を管理する端末をゲートウェーのみとすることで各無線端末に必要なメモリサイズの削減を実現している。 In addition, in the wireless system disclosed in Non-Patent Document 1, the memory size required for each wireless terminal is reduced by using only the gateway as the terminal that finally manages the connection relationship.
特開２００８－１１８３５１号公報JP 2008-118351 A
　無線メッシュネットワークで構成される無線システムは、ビルディング又はマンションに導入される場合に、事前に無線メッシュネットワークが安定して運用可能か否かを調査する必要がある。特許文献１および非特許文献１に示された無線メッシュネットワークで構成される無線システムは、安定して運用可能か否かを判定するために、全無線端末同士の接続関係を収集する必要がある。特許文献１および非特許文献１に示された無線メッシュネットワークで構成される無線システムは、全無線端末同士の接続関係の収集に時間を要し、安定して運用可能か否かを判定するために要する時間が長くなる可能性がある。 When a wireless system composed of a wireless mesh network is introduced into a building or a condominium, it is necessary to investigate whether the wireless mesh network can be stably operated in advance. The wireless system configured by the wireless mesh network disclosed in Patent Document 1 and Non-Patent Document 1 needs to collect connection relationships between all wireless terminals in order to determine whether or not it can be stably operated. . The wireless system configured by the wireless mesh network disclosed in Patent Document 1 and Non-Patent Document 1 requires time to collect connection relationships between all wireless terminals, and determines whether or not it can be stably operated. May take longer.
　本発明は、上記に鑑みてなされたものであって、無線システムを安定して運用可能か否かを判定するために要する時間を抑制することができる推定装置を得ることを目的とする。 The present invention has been made in view of the above, and an object of the present invention is to obtain an estimation device capable of suppressing the time required to determine whether or not a wireless system can be stably operated.
　上述した課題を解決し、目的を達成するために、本発明の推定装置は、行方向および列方向に沿って並べられた複数の無線子機と、無線親機とで無線メッシュを構成する無線システムにおける前記無線メッシュの接続関係を取得する推定装置である。推定装置は、前記複数の無線子機の配置情報を記憶した情報記憶手段と、前記複数の無線子機のうち一部の無線子機と前記無線親機との親子間接続関係および一部の無線子機同士の子機間接続関係を調査する調査手段と、前記調査手段が調査した前記親子間接続関係および前記子機間接続関係を調査結果として記憶する調査結果記憶手段と、前記調査結果および前記配置情報に基づいて、前記無線子機のうち、前記子機間接続関係が調査できなかった未調査無線子機同士の接続関係を、前記未調査無線子機同士の配置と同じ配置関係にある無線子機同士のうち、前記調査結果があるものの前記子機間接続関係から推定する推定手段と、を備えることを特徴とする。 In order to solve the above-described problems and achieve the object, the estimation apparatus according to the present invention is a wireless that configures a wireless mesh with a plurality of wireless slave devices arranged in the row direction and the column direction, and the wireless master device. It is the estimation apparatus which acquires the connection relation of the said wireless mesh in a system. The estimation apparatus includes an information storage unit that stores arrangement information of the plurality of wireless slave units, a parent-child connection relationship between a part of the plurality of wireless slave units and the wireless master unit, and a part of the relationship. Investigation means for investigating the inter-slave connection between wireless slave units, investigation result storage means for storing the inter-parent connection relation and the inter-slave connection relation investigated by the investigation means, and the investigation result Based on the arrangement information, among the wireless slave units, the connection relationship between unexamined wireless slave units whose connection relationship between the slave units could not be investigated is the same arrangement relationship as the arrangement of the unexamined wireless slave units. There is an estimation means for estimating from the connection relationship between the slave units although there is the investigation result among the wireless slave units in the network.
　本発明に係る推定装置は、無線システムを安定して運用可能か否かを判定するために要する時間を抑制することができる、という効果を奏する。 The estimation apparatus according to the present invention has an effect that the time required to determine whether or not the wireless system can be stably operated can be suppressed.
