Description

本発明は、通信機、通信システム、通信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 communication device, a communication system, a communication method, and a program.

近年、スマートホンやタブレットと呼ばれる電子情報機器の普及に伴い、ＷＡＮ（Wide Area Network）とＬＡＮ（Local Area Network）とを中継する、モバイルルータと呼ばれる、持ち運び用の無線中継器が多く使われるようになった。   In recent years, with the spread of electronic information devices called smartphones and tablets, portable wireless repeaters called mobile routers that relay between WAN (Wide Area Network) and LAN (Local Area Network) are often used. Became.

このモバイルルータは、持ち運ばれている間は電池で駆動されるため動作時間が限られる。そこで、電池による動作時間を長時間化する方法が用いられている。   Since this mobile router is driven by a battery while being carried, the operation time is limited. Therefore, a method of extending the operation time by the battery is used.

例えば、モバイルルータが一定時間通信していないと、ＣＰＵ（Central Processing Unit；中央処理装置）のクロック速度を低速化して消費電力を抑制する方法がある。或いは、モバイルルータの動作状況に変化が無く一定時間経過すると、液晶表示装置の表示を一時停止して消費電力を抑制する方法もある。更に、使用者がハードウェアスイッチや初期設定ソフトウェアを用いて入力することにより、モバイルルータのＣＰＵのクロック速度を低速化する等の設定が可能になっているものもある。   For example, when the mobile router has not communicated for a certain period of time, there is a method of reducing power consumption by reducing the clock speed of a CPU (Central Processing Unit). Alternatively, there is a method of suppressing power consumption by temporarily stopping the display of the liquid crystal display device when a certain period of time has passed without any change in the operation status of the mobile router. In addition, there is a configuration in which the user can input settings using a hardware switch or initial setting software to reduce the clock speed of the CPU of the mobile router.

また、ＬＡＮの通信手段にIEEE（The Institute of Electrical and Electronics Engineers,Inc.）が定めるIEEE802.11に基づく無線ＬＡＮとBluetooth（登録商標）（以下、ＢＴ）を有するモバイルルータがある。このようなモバイルルータでは、使用者の設定によりＢＴを選択して消費電力を抑制することが出来る。   In addition, there is a mobile router having a wireless LAN based on IEEE802.11 and Bluetooth (registered trademark) (hereinafter referred to as BT) defined by IEEE (The Institute of Electrical and Electronics Engineers, Inc.) as LAN communication means. In such a mobile router, power consumption can be suppressed by selecting a BT according to user settings.

上記の様にＬＡＮの通信手段に無線ＬＡＮとＢＴを有するモバイルルータには、次のような機能をもつものがある。即ち、モバイルルータが一定時間使用されないと、ＷＡＮと無線ＬＡＮが停止し、消費電力が少ないＢＴだけが無線の待ち受け状態となり、ＢＴで起動信号を受信すると再びモバイルルータ全体が起動（Wakeup）するものがある。   Some mobile routers having wireless LAN and BT as LAN communication means as described above have the following functions. That is, when the mobile router is not used for a certain period of time, the WAN and the wireless LAN are stopped, only the BT with low power consumption is in a standby state, and when the activation signal is received by the BT, the entire mobile router is activated again (Wakeup). There is.

特許文献１によれば、情報処理装置が２つの通信デバイス（例えば無線ＬＡＮとＢＴ）を備え、装置本体の電源がオフ状態の待機中はWakeupに必要な方だけに電源を供給することで、無駄な電力消費を避けながらWakeupを待機することができる。   According to Patent Document 1, an information processing apparatus includes two communication devices (for example, a wireless LAN and a BT), and power is supplied only to a person who is required for wakeup while the apparatus main body is in a standby state. You can wait for Wakeup while avoiding unnecessary power consumption.

特開2004-038295号公報JP 2004-038295 A

しかし、特許文献１に示される方法によると、装置がWakeupした時に電池残量に関係なく、全ての通信デバイスに電源が入るため、Wakeup後の装置の電池駆動による動作時間を長時間化する効果はない。   However, according to the method disclosed in Patent Document 1, since all communication devices are turned on regardless of the remaining battery level when the device wakes up, the effect of extending the operation time of the device after battery wakeup by battery driving is increased. There is no.

本発明の通信機は、電池残量が少ない場合に、消費電力の少ない通信デバイスを選択することで、電池駆動による長時間動作を実現する事を目的とする。   An object of the communication device of the present invention is to realize a long-time operation by battery driving by selecting a communication device with low power consumption when the remaining battery level is low.

上記の目的を達成するために、本発明の通信機は、接続先と通信する第１の通信部と、前記接続先と通信する前記第１の通信部と比べて消費電力の少ない第２の通信部と、電池の残量の値を信号として出力する電池監視部と、前記電池監視部が出力する値が所定の値以上であれば前記第１の通信部を動作させ、前記電池監視部が出力する値が所定の値より小さければ前記第１の通信部の動作を停止して前記第２の通信部を動作させる制御部とを備える。   In order to achieve the above object, a communication device according to the present invention includes a first communication unit that communicates with a connection destination and a second communication unit that consumes less power than the first communication unit that communicates with the connection destination. A communication unit; a battery monitoring unit that outputs a value of a remaining battery level as a signal; and a battery monitoring unit that operates the first communication unit if a value output by the battery monitoring unit is equal to or greater than a predetermined value. And a control unit that stops the operation of the first communication unit and operates the second communication unit if the value output by the controller is smaller than a predetermined value.

本発明によれば、通信機は電池残量が少ない場合に、消費電力の少ない通信デバイスを選択することで、電池駆動による長時間動作を実現することができる。   According to the present invention, when the battery level is low, the communication device can realize a long-time operation by battery driving by selecting a communication device with low power consumption.

［第１の実施形態］
次に、本発明の実施の形態について図面を参照して詳細に説明する。
［構成の説明］
図１に第１の実施形態の構成を示す。 [First Embodiment]
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[Description of configuration]
FIG. 1 shows the configuration of the first embodiment.

本実施形態の無線通信機１００は、モバイルルータである。無線通信機１００は、ＷＡＮ無線部１０１、無線ＬＡＮ部１０２、ＢＴ無線部１０３、電池監視部１０４、電池１０５、制御部１０６、および記憶部１０７から構成される。   The wireless communication device 100 of this embodiment is a mobile router. The wireless communication device 100 includes a WAN wireless unit 101, a wireless LAN unit 102, a BT wireless unit 103, a battery monitoring unit 104, a battery 105, a control unit 106, and a storage unit 107.

ＷＡＮ無線部１０１は、ＰＬＭＮ（public land mobile network；地上波公共移動通信ネットワーク）の基地局と無線で通信するＷＡＮ通信用の回路である。ＷＡＮ無線部１０１とＰＬＭＮの基地局の通信には、IMT-2000（International Mobile Telecommunication 2000)、LTE（Long Term Evolution）、WiMAX（Worldwide Interoperability for Microwave Access）などの通信方式を用いる。   The WAN wireless unit 101 is a WAN communication circuit that communicates wirelessly with a base station of a PLMN (public land mobile network). For communication between the WAN radio unit 101 and the PLMN base station, communication systems such as IMT-2000 (International Mobile Telecommunication 2000), LTE (Long Term Evolution), and WiMAX (Worldwide Interoperability for Microwave Access) are used.

また、無線ＬＡＮ部１０２は、スマートホンやタブレット端末などの子機と無線ＬＡＮで通信するＬＡＮ通信用の回路である。この無線ＬＡＮ部１０２の通信方式は、無線ＬＡＮの規格であるIEEE（The Institute of Electrical and Electronics Engineers,Inc.）が定めるIEEE802.11とする。   The wireless LAN unit 102 is a circuit for LAN communication that communicates with a slave unit such as a smart phone or a tablet terminal via a wireless LAN. The communication method of the wireless LAN unit 102 is IEEE802.11 defined by IEEE (The Institute of Electrical and Electronics Engineers, Inc.), which is a wireless LAN standard.

そして、ＢＴ無線部１０３は、スマートホンやタブレット端末などの子機とＢＴで通信するＬＡＮ通信用の回路である。このＢＴ無線部１０３は、無線ＬＡＮ部１０２と比べて通信速度が遅く、電波の到達距離も短いが、消費電力は通信中も通信待機中も一般的に明らかに小さい。   The BT wireless unit 103 is a circuit for LAN communication that communicates with a child device such as a smart phone or a tablet terminal via the BT. The BT wireless unit 103 has a lower communication speed and shorter radio wave reach than the wireless LAN unit 102, but the power consumption is generally clearly smaller during communication and during communication standby.

更に、電池監視部１０４は電池１０５の残りの容量を監視して数値化した信号を出力する回路であり、電池１０５は無線通信機１００に電源を供給する蓄電池や乾電池である。また、制御部１０６は無線通信機１００の各構成要素を制御するＣＰＵであり、記憶部１０７は情報を記憶するための記憶素子である。
［動作の説明］
次に、本実施形態の動作について図２を参照して詳細に説明する。 Further, the battery monitoring unit 104 is a circuit that monitors the remaining capacity of the battery 105 and outputs a digitized signal. The battery 105 is a storage battery or a dry battery that supplies power to the wireless communication device 100. The control unit 106 is a CPU that controls each component of the wireless communication device 100, and the storage unit 107 is a storage element for storing information.
[Description of operation]
Next, the operation of the present embodiment will be described in detail with reference to FIG.

図２において、無線通信機１００に電源が投入され無線通信機１００が動作を開始する。この動作開始の時点では、ＷＡＮ無線部１０１、無線ＬＡＮ部１０２、ＢＴ無線部１０３のいずれの無線部にも電源は供給されていない。   In FIG. 2, the wireless communication device 100 is turned on and the wireless communication device 100 starts operating. At the start of this operation, power is not supplied to any of the wireless units of the WAN wireless unit 101, the wireless LAN unit 102, and the BT wireless unit 103.

無線通信機１００が動作を開始すると、制御部１０６はＬＡＮ自動切換モードか否かを判断する（Ｓ１０１）。このＬＡＮ自動切換モードでは、電池１０５の残量に応じて、ＬＡＮの通信を無線ＬＡＮとするかＢＴとするかの選択が自動で行われる。そして、ＬＡＮ自動切換モードでない場合は、無線通信機１００の使用者がＬＡＮの通信を無線ＬＡＮとするかＢＴとするかを手動で選択する。ＬＡＮ自動切換モードか否かの設定情報は、使用者がモバイルルータ本体のキーボード等の入力手段、またはスマートホンやタブレット端末などの外部機器から専用アプリケーションなどを用いて、予め記憶部１０７に記憶しておく。そして、制御部１０６は、記憶部１０７のこの設定情報に従ってＬＡＮ自動切換モードか否かを判断する（Ｓ１０１）。   When the wireless communication device 100 starts operation, the control unit 106 determines whether or not the LAN automatic switching mode is set (S101). In this LAN automatic switching mode, selection of whether the LAN communication is a wireless LAN or BT is automatically performed according to the remaining amount of the battery 105. If the mode is not the LAN automatic switching mode, the user of the wireless communication device 100 manually selects whether the LAN communication is a wireless LAN or a BT. Setting information as to whether or not the LAN is in the automatic LAN switching mode is stored in the storage unit 107 in advance by a user using an input unit such as a keyboard of the mobile router body or a dedicated application from an external device such as a smartphone or a tablet terminal. Keep it. Then, the control unit 106 determines whether or not the LAN automatic switching mode is in accordance with the setting information in the storage unit 107 (S101).

ステップＳ１０１で制御部１０６がＬＡＮ自動切換モードでないと判断すると（Ｓ１０１でＮ）ステップＳ１０７にすすむ。ステップＳ１０７では、制御部１０６はＬＡＮ通信用の無線部として無線ＬＡＮ部１０２を選択して、制御部１０６は無線ＬＡＮ部１０２の電源をオンにする。そして、無線ＬＡＮ部１０２に電源が供給され、無線ＬＡＮ部１０２は子機と接続して通信できる状態となる（Ｓ１０７）。次いで、制御部１０６はＷＡＮ無線部１０１の電源をオンにして、ＷＡＮ無線部１０１にも電源が供給され、ＷＡＮ無線部１０１はＷＡＮの基地局と接続して通信準備が完了する（Ｓ１０８）。   If the control unit 106 determines in step S101 that the LAN automatic switching mode is not set (N in S101), the process proceeds to step S107. In step S107, the control unit 106 selects the wireless LAN unit 102 as a wireless unit for LAN communication, and the control unit 106 turns on the power of the wireless LAN unit 102. Then, power is supplied to the wireless LAN unit 102, and the wireless LAN unit 102 is in a state where it can communicate with the slave unit (S107). Next, the control unit 106 turns on the power of the WAN radio unit 101, and power is also supplied to the WAN radio unit 101. The WAN radio unit 101 is connected to the WAN base station and communication preparation is completed (S108).

一方、ステップＳ１０１で、制御部１０６がＬＡＮ自動切換モードであると判断すると（Ｓ１０１でＹ）ステップＳ１０２にすすむ。ステップＳ１０２では、制御部１０６は電池監視部１０４が電池残量として出力する信号の値が、記憶部１０７に予め記憶されている電池残量の設定値以上か否かを判断する（Ｓ１０２）。ここで記憶部１０７にあらかじめ記憶されている電池残量の設定値は、記憶部１０７に最初から記憶されていても良いし、使用者が任意の設定値を記憶させることが出来ても良い。   On the other hand, when the control unit 106 determines that the LAN automatic switching mode is set in step S101 (Y in S101), the process proceeds to step S102. In step S102, the control unit 106 determines whether or not the value of the signal output by the battery monitoring unit 104 as the remaining battery level is equal to or greater than the set value of the remaining battery level stored in advance in the storage unit 107 (S102). Here, the setting value of the remaining battery level stored in advance in the storage unit 107 may be stored in the storage unit 107 from the beginning, or the user may be able to store an arbitrary setting value.

ステップＳ１０２で電池残量が設定値以上と判断されると（ステップＳ１０２でＹ）ステップＳ１０３にすすみ、ステップＳ１０２で電池残量が設定値以上でないと判断されると（ステップＳ１０２でＮ）ステップＳ１０６にすすむ。   If it is determined in step S102 that the remaining battery level is equal to or greater than the set value (Y in step S102), the process proceeds to step S103. If it is determined in step S102 that the remaining battery level is not equal to or greater than the set value (N in step S102), step S106. Proceed.

ステップＳ１０３では、制御部１０６はＬＡＮの無線部として無線ＬＡＮ部１０２を選択して、制御部１０６は無線ＬＡＮ部１０２の電源をオンにする。そして、無線ＬＡＮ部１０２に電源が供給され、無線ＬＡＮ部１０２は子機と接続して通信できる状態となる（Ｓ１０３）。次いで、制御部１０６はＷＡＮ無線部１０１の電源をオンにして、ＷＡＮ無線部１０１にも電源が供給され、ＷＡＮ無線部１０１はＷＡＮの基地局と接続して通信する準備が完了する（Ｓ１０４）。 ステップＳ１０４で無線ＬＡＮ部１０２に続きＷＡＮ無線部１０１にも電源が入ると、制御部１０６は電池監視部１０４が電池残量として出力する信号の値が、記憶部１０７に予め記憶されている電池残量の設定値以上か否かを判断する（Ｓ１０５）。ステップＳ１０５で電池残量が設定値以上と判断されると（ステップＳ１０５でＹ）ステップＳ１０５に戻り、ステップＳ１０５で電池残量が設定値以上でないと判断されると（ステップＳ１０５でＮ）ステップＳ１０６にすすむ。   In step S103, the control unit 106 selects the wireless LAN unit 102 as the wireless unit of the LAN, and the control unit 106 turns on the power of the wireless LAN unit 102. Then, power is supplied to the wireless LAN unit 102, and the wireless LAN unit 102 is connected to the slave unit and can communicate (S103). Next, the control unit 106 turns on the power of the WAN wireless unit 101 and the power is also supplied to the WAN wireless unit 101, and the WAN wireless unit 101 is ready to connect to and communicate with the WAN base station (S104). . When the WAN wireless unit 101 is turned on after the wireless LAN unit 102 in step S104, the control unit 106 stores the battery value that the battery monitoring unit 104 outputs as the remaining battery level in the storage unit 107 in advance. It is determined whether the remaining amount is equal to or greater than the set value (S105). If it is determined in step S105 that the remaining battery level is equal to or greater than the set value (Y in step S105), the process returns to step S105. If it is determined in step S105 that the remaining battery level is not equal to or greater than the set value (N in step S105), step S106. Proceed.

一方、ステップＳ１０６では制御部１０６はＬＡＮの無線部としてＢＴ無線部１０３を選択して、制御部１０６はＢＴ無線部１０３の電源をオンにする。そして、ＢＴ無線部１０３に電源が供給され、ＢＴ無線部１０３は子機と接続して通信できる状態となる（Ｓ１０６）。次に、制御部１０６はＷＡＮ無線部１０１の電源をオンにして、ＷＡＮ無線部１０１にも電源が供給され、ＷＡＮ無線部１０１はＷＡＮの基地局と接続して通信する準備が完了する（Ｓ１０７）。   On the other hand, in step S106, the control unit 106 selects the BT radio unit 103 as the LAN radio unit, and the control unit 106 turns on the power of the BT radio unit 103. Then, power is supplied to the BT wireless unit 103, and the BT wireless unit 103 is in a state where it can communicate with the slave unit (S106). Next, the control unit 106 turns on the power of the WAN wireless unit 101 and power is also supplied to the WAN wireless unit 101, and the WAN wireless unit 101 is ready to connect to and communicate with the WAN base station (S107). ).

尚、ＷＡＮ、無線ＬＡＮ、ＢＴの接続および通信の手順は、モバイルルータやスマートホンで一般的に行われているため、詳細の説明は省略する。   Note that the WAN, wireless LAN, and BT connection and communication procedures are generally performed by mobile routers and smart phones, and thus detailed description thereof is omitted.

以上説明した様に、本実施形態に示す無線通信機１００は電池残量が少ない場合に、ＬＡＮ通信用の無線部として無線ＬＡＮ部１０２を使用せず、ＢＴ無線部１０３を使用する。一般に、ＢＴは無線ＬＡＮと比べて、通信速度は遅いが通信で消費される電力が極めて小さい。無線通信機１００の電池残量が少なくなった場合、通信速度は遅くなっても通信が継続出来た方が実用上好ましい。   As described above, the wireless communication device 100 according to the present embodiment uses the BT wireless unit 103 instead of the wireless LAN unit 102 as a wireless unit for LAN communication when the remaining battery level is low. In general, BT has a slower communication speed than a wireless LAN, but consumes very little power. When the remaining battery level of the wireless communication device 100 decreases, it is practically preferable that communication can be continued even if the communication speed is slow.

以上のようにして、本実施形態の無線通信機１００は、電池残量が少なくなった場合にＬＡＮ側通信手段として無線ＬＡＮより消費電力の少ない通信デバイスであるＢＴを選択することで、電池駆動による長時間動作を実現することができる。
［第２の実施形態］

［構成の説明］
図３に第２の実施形態の構成を示す。 As described above, the wireless communication device 100 according to the present embodiment selects the BT that is a communication device that consumes less power than the wireless LAN as the LAN-side communication unit when the remaining battery level is low. Long-time operation can be realized.
[Second Embodiment]
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[Description of configuration]
FIG. 3 shows the configuration of the second embodiment.

本実施形態の無線通信機１００は、モバイルルータであり、第１の実施形態で示した図１の構成に加えて、計時部１０８を備える。計時部１０８は時間を計時して時間の値を信号として出力する計時回路である。
［動作の説明］
次に、本実施形態の動作について図４および図５を参照して詳細に説明する。 The wireless communication device 100 of the present embodiment is a mobile router, and includes a timer unit 108 in addition to the configuration of FIG. 1 shown in the first embodiment. The timer 108 is a timer circuit that measures time and outputs the time value as a signal.
[Description of operation]
Next, the operation of this embodiment will be described in detail with reference to FIG. 4 and FIG.

図４では無線通信機１００が動作を開始し、後述のスリープ状態になるまでの動作を示し、図５ではスリープ状態の無線通信機１００が後述のWakeup信号を受信してから通信を開始する動作を説明する。   FIG. 4 shows an operation until the wireless communication device 100 starts operating and enters a sleep state to be described later, and FIG. 5 shows an operation in which the wireless communication device 100 in the sleep state starts communication after receiving a wakeup signal described later. Will be explained.

まず、図４において、無線通信機１００に電源が投入され動作を開始し、子機であるスマートホンやタブレット端末と、無線ＬＡＮ部１０２またはＢＴ無線部１０３が接続し通信を開始する（Ｓ２０１）。ここで、ＬＡＮの通信手段として無線ＬＡＮを用いるか、ＢＴを用いるかは使用者が予め設定しているものとする。   First, in FIG. 4, the wireless communication device 100 is turned on to start operation, and the smart phone or tablet terminal as a slave device is connected to the wireless LAN unit 102 or the BT wireless unit 103 to start communication (S201). . Here, it is assumed that the user has previously set whether to use a wireless LAN or BT as the LAN communication means.

ステップＳ２０１に次いで、ＷＡＮ無線部１０１がＷＡＮの接続および通信を開始する（Ｓ２０２）。ステップＳ２０２の後、制御部１０６は、ＷＡＮ無線部１０１、無線ＬＡＮ部１０２およびＢＴ無線部１０３のどれかが通信中かどうかを判断する（Ｓ２０３）。   Subsequent to step S201, the WAN wireless unit 101 starts WAN connection and communication (S202). After step S202, the control unit 106 determines whether any of the WAN wireless unit 101, the wireless LAN unit 102, and the BT wireless unit 103 is communicating (S203).

ステップＳ２０３で、制御部１０６がＷＡＮ無線部１０１、無線ＬＡＮ部１０２およびＢＴ無線部１０３のどれかが通信中であると判断すると（Ｓ２０３でＹ）ステップＳ２０３にもどる。一方、ステップＳ２０３で、制御部１０６がＷＡＮ無線部１０１、無線ＬＡＮ部１０２およびＢＴ無線部１０３のどれも通信中でないと判断すると（Ｓ２０３でＮ）、計時部１０８は計時をリセットして時間を計り始める（Ｓ２０４）。   If the control unit 106 determines in step S203 that any one of the WAN wireless unit 101, the wireless LAN unit 102, and the BT wireless unit 103 is communicating (Y in S203), the process returns to step S203. On the other hand, when the control unit 106 determines in step S203 that none of the WAN wireless unit 101, the wireless LAN unit 102, and the BT wireless unit 103 is communicating (N in S203), the time counting unit 108 resets the time measurement and sets the time. Start measuring (S204).

ステップＳ２０４に続いて、制御部１０６は、ＷＡＮ無線部１０１、無線ＬＡＮ部１０２およびＢＴ無線部１０３のどれかが通信中かどうかを判断する（Ｓ２０５）。ステップＳ２０５で、制御部１０６がＷＡＮ無線部１０１、無線ＬＡＮ部１０２およびＢＴ無線部１０３のどれかが通信中であると判断すると（Ｓ２０５でＹ）ステップＳ２０３にもどる。一方、ステップＳ２０５で、制御部１０６がＷＡＮ無線部１０１、無線ＬＡＮ部１０２およびＢＴ無線部１０３のどれも通信中でないと判断すると（Ｓ２０５でＮ）、ステップＳ２０６にすすむ。   Subsequent to step S204, the control unit 106 determines whether any of the WAN wireless unit 101, the wireless LAN unit 102, and the BT wireless unit 103 is communicating (S205). If the control unit 106 determines in step S205 that any one of the WAN wireless unit 101, the wireless LAN unit 102, and the BT wireless unit 103 is communicating (Y in S205), the process returns to step S203. On the other hand, when the control unit 106 determines in step S205 that none of the WAN wireless unit 101, the wireless LAN unit 102, and the BT wireless unit 103 is communicating (N in S205), the process proceeds to step S206.

ステップＳ２０６では、制御部１０６は、計時部１０４が計時する時間と、予め記憶部１０７に記憶されている設定時間と比較し、設定時間になったかどうかを判断する（Ｓ２０６）。ステップＳ２０６で、制御部１０６が設定時間でないと判断すると（Ｓ２０６でＮ）ステップＳ２０５に戻る。一方、ステップＳ２０６で制御部１０６が設定時間であると判断すると（Ｓ２０６でＹ）、制御部１０６は、ＷＡＮ無線部１０１と無線ＬＡＮ部１０２の電源供給を停止し（Ｓ２０７）、無線通信機１００はスリープ状態になる。   In step S206, the control unit 106 compares the time measured by the time measuring unit 104 with the set time stored in advance in the storage unit 107, and determines whether the set time has been reached (S206). If the control unit 106 determines that it is not the set time in step S206 (N in S206), the process returns to step S205. On the other hand, when the control unit 106 determines in step S206 that it is the set time (Y in S206), the control unit 106 stops power supply to the WAN wireless unit 101 and the wireless LAN unit 102 (S207), and the wireless communication device 100 Goes to sleep.

このように、無線通信機１００が通信をしないとスリープ状態になる事で、無駄な電力消費を低減することが出来る。しかし、通信が途絶えると直ちに無線通信機１００がスリープ状態になってしまうと、通信の瞬断でもスリープ状態となってしまい、使用に不都合である。そこで、無線通信機１００が通信をしないと一定時間後にスリープ状態となる様に、一定時間を計時するのが計時部１０８である。   As described above, when the wireless communication device 100 does not perform communication, it enters a sleep state, so that wasteful power consumption can be reduced. However, if the wireless communication device 100 immediately enters a sleep state when communication is interrupted, the communication device is in a sleep state even if communication is interrupted, which is inconvenient for use. Therefore, the time measuring unit 108 measures a certain time so that the wireless communication device 100 enters a sleep state after a certain time if communication is not performed.

尚、無線通信機１００が通信をしないと一定時間後にスリープ状態になること、および無線ＬＡＮの電源供給を停止して、消費電力が無線ＬＡＮより少ないＢＴを動作させて待機することは、市販のモバイルルータで一般的に行われている。 次に図５を用いて、無線通信機１００がスリープ状態から、Wakeup信号を受信して無線通信を開始する動作を説明する。   It should be noted that when the wireless communication device 100 does not communicate, it goes into a sleep state after a certain time, and the wireless LAN power supply is stopped and the BT with less power consumption than the wireless LAN is operated to stand by. Commonly done in mobile routers. Next, an operation in which the wireless communication device 100 receives a wakeup signal and starts wireless communication from the sleep state will be described with reference to FIG.

無線通信機１００がスリープ状態であると、ＷＡＮ無線部１０１と無線ＬＡＮ部１０２の電源供給は停止され、無線部としてはＢＴ無線部１０３だけが動作している。そして、スマートホンやタブレット端末などの子機から、無線通信機１００が通信を開始することを指示するＢＴによるWakeup信号を、ＢＴ無線部１０３が受信すると無線通信機１００は起動して（Ｓ３０１）、ステップＳ３０２にすすむ。   When the wireless communication device 100 is in the sleep state, power supply to the WAN wireless unit 101 and the wireless LAN unit 102 is stopped, and only the BT wireless unit 103 is operating as the wireless unit. Then, when the BT wireless unit 103 receives a BT wakeup signal instructing the wireless communication device 100 to start communication from a child device such as a smart phone or a tablet terminal, the wireless communication device 100 is activated (S301). The process proceeds to step S302.

ここで、スマートホンやタブレット端末などの子機が無線通信機１００に対してＢＴによるWakeup信号を送信し、無線通信機１００が起動することは、市販のモバイルルータで一般的に行われている。 ステップＳ３０２で、制御部１０６はＬＡＮ自動切換モードか否かを判断する（Ｓ３０２）。このＬＡＮ自動切換モードを使用するか否かの設定情報は、使用者がモバイルルータ本体のキーボード等の入力手段、またはスマートホンやタブレット端末などの外部機器から専用アプリケーションなどを用いて、予め記憶部１０７に記憶しておく。そして、ステップＳ３０２で制御部１０６は記憶部１０７の設定情報に従って、無線通信機１００がＬＡＮ自動切換モードか否かを判断する（Ｓ３０２）。   Here, a slave device such as a smart phone or a tablet terminal transmits a wake-up signal by BT to the wireless communication device 100, and the wireless communication device 100 is generally activated by a commercially available mobile router. . In step S302, the control unit 106 determines whether the LAN automatic switching mode is set (S302). The setting information as to whether or not to use this automatic LAN switching mode is stored in advance by the user using an input means such as a keyboard of the mobile router body or a dedicated application from an external device such as a smartphone or a tablet terminal. This is stored in 107. In step S302, the control unit 106 determines whether the wireless communication device 100 is in the LAN automatic switching mode according to the setting information in the storage unit 107 (S302).

ステップＳ３０２で、制御部１０６がＬＡＮ自動切換モードであると判断すると（Ｓ３０２でＹ）ステップＳ３０３にすすみ、ステップＳ３０２で、制御部１０６がＬＡＮ自動切換モードでないと判断すると（Ｓ３０２でＮ）ステップＳ３０６にすすむ。   If it is determined in step S302 that the control unit 106 is in the LAN automatic switching mode (Y in S302), the process proceeds to step S303. In step S302, if it is determined that the control unit 106 is not in the LAN automatic switching mode (N in S302), step S306. Proceed.

ステップＳ３０３では、制御部１０６は、電池監視部１０４が電池残量として出力する信号の値が記憶部１０７に予め記憶されている電池残量の設定値以上か否かを判断する（Ｓ３０３）。ここで記憶部１０７にあらかじめ記憶されている電池残量の設定値は、記憶部１０７に最初から記憶されていても良いし、使用者が任意の設定値を記憶させることが出来ても良い。   In step S303, the control unit 106 determines whether or not the value of the signal output by the battery monitoring unit 104 as the remaining battery level is equal to or greater than the set value of the remaining battery level stored in advance in the storage unit 107 (S303). Here, the setting value of the remaining battery level stored in advance in the storage unit 107 may be stored in the storage unit 107 from the beginning, or the user may be able to store an arbitrary setting value.

ステップＳ３０３で電池残量が設定値以上でないと判断されると（ステップＳ３０３でＮ）ステップＳ３０４にすすみ、ステップＳ３０３で電池残量が設定値以上と判断されると（ステップＳ３０３でＹ）ステップＳ３０６にすすむ。   If it is determined in step S303 that the remaining battery level is not equal to or greater than the set value (N in step S303), the process proceeds to step S304. If it is determined in step S303 that the remaining battery level is equal to or greater than the set value (Y in step S303), step S306 is performed. Proceed.

ステップＳ３０４では、制御部１０６はＷＡＮ無線部１０１の電源をオンにして、ＷＡＮ無線部１０１に電源が供給され、ＷＡＮ無線部１０１はＷＡＮの基地局と接続する（Ｓ３０４）。次いで、ＷＡＮ無線部１０１、および既に接続中のＢＴ無線部１０３がそれぞれの接続先と通信を開始する（Ｓ３０５）。ステップＳ３０５でＷＡＮ無線部１０１とＢＴ無線部１０３がそれぞれの接続先と通信を開始すると、図４のステップＳ２０３にすすむ。   In step S304, the control unit 106 turns on the power of the WAN radio unit 101, power is supplied to the WAN radio unit 101, and the WAN radio unit 101 is connected to a WAN base station (S304). Next, the WAN radio unit 101 and the already connected BT radio unit 103 start communication with the respective connection destinations (S305). When the WAN wireless unit 101 and the BT wireless unit 103 start communication with the respective connection destinations in step S305, the process proceeds to step S203 in FIG.

一方、ステップＳ３０６では、制御部１０６はＷＡＮ無線部１０１と無線ＬＡＮ部１０２の電源をオンにして、ＷＡＮ無線部１０１と無線ＬＡＮ部１０２に電源が供給される。そして、ＷＡＮ無線部１０１と無線ＬＡＮ部１０２が動作を開始して、ＷＡＮ無線部１０１はＷＡＮの基地局と接続し、無線ＬＡＮ部１０２は子機と接続する（Ｓ３０６）。次いで、ＷＡＮ無線部１０１と無線ＬＡＮ部１０２がそれぞれの接続先と通信を開始する（Ｓ３０７）。ステップＳ３０７でＷＡＮ無線部１０１と無線ＬＡＮ部１０２がそれぞれの接続先と通信を開始すると、図４のステップＳ２０３にすすむ。   On the other hand, in step S <b> 306, the control unit 106 turns on the power of the WAN wireless unit 101 and the wireless LAN unit 102, and power is supplied to the WAN wireless unit 101 and the wireless LAN unit 102. Then, the WAN wireless unit 101 and the wireless LAN unit 102 start operation, the WAN wireless unit 101 is connected to the WAN base station, and the wireless LAN unit 102 is connected to the slave unit (S306). Next, the WAN wireless unit 101 and the wireless LAN unit 102 start communication with each connection destination (S307). When the WAN wireless unit 101 and the wireless LAN unit 102 start communication with the respective connection destinations in step S307, the process proceeds to step S203 in FIG.

尚、ステップＳ３０６で、制御部１０６はＢＴ無線部１０３への電源供給を停止すると、更に低消費電力化が可能であるが、その場合は図２のステップＳ２０７で、制御部１０６がＢＴ無線部１０３の電源を入れる動作を追加する。   In step S306, when the control unit 106 stops supplying power to the BT radio unit 103, the power consumption can be further reduced. In this case, in step S207 of FIG. The operation to turn on the power of 103 is added.

以上説明したように、本実施形態の無線通信機１００は、Wakeupした時点の電池残量が少ない場合にＬＡＮ側通信手段として無線ＬＡＮより消費電力の少ないＢＴを選択することで、電池駆動による長時間動作を実現することができる。
［第３の実施形態］
次に、第３の実施の形態について図を参照して説明する。 As described above, the wireless communication device 100 according to the present embodiment selects a BT that consumes less power than a wireless LAN as a LAN-side communication unit when the remaining battery level at the time of wakeup is low, thereby increasing the battery-driven length. Time operation can be realized.

Then, the control unit 203 operates the first communication unit 201 if the value output from the battery monitoring unit 204 is equal to or greater than a predetermined value. Further, the control unit 203 stops the operation of the first communication unit 201 and operates the second communication unit 202 if the value output from the battery monitoring unit 204 is smaller than a predetermined value.
