Description
本発明は無線ＬＡＮの電波を利用した設備案内装置に関し、特に案内する設備の利用可否状況をも案内することが可能な設備案内装置に関する。 The present invention relates to a facility guidance device using radio waves of a wireless LAN, and more particularly to a facility guidance device capable of guiding the availability of a facility to be guided.
従来、無線ＬＡＮ（Ｗｉ−Ｆｉ）等の電波を発信する装置においては、その装置が定期的に発射するビーコン信号にＳＳＩＤ（サービスセット識別子Ｓｅｒｖｉｃｅ Ｓｅｔ Ｉｄｅｎｔｉｆｉｅｒ）が含まれている。無線ＬＡＮを使用するユーザーは、無線ＬＡＮ機能を持つ端末装置が前記ビーコン信号を受信し、ビーコン電波の強度によってＳＳＩＤを並べ変えて表示された結果を確認する事で、無線ＬＡＮ装置の有無やその無線ＬＡＮ装置と接続が可能であるかを判別していた。 2. Description of the Related Art Conventionally, in a device that transmits radio waves such as a wireless LAN (Wi-Fi), an SSID (Service Set Identifier Service Set Identifier) is included in a beacon signal that the device periodically emits. A user who uses a wireless LAN receives a beacon signal from a terminal device having a wireless LAN function, confirms the displayed result by rearranging the SSID according to the strength of the beacon radio wave, and the presence or absence of the wireless LAN device. It has been determined whether the wireless LAN device can be connected.
一方、無線ＬＡＮの電波の到達方法を検知する技術が特許文献１に開示されており、これらの技術を組み合わせて設備に無線ＬＡＮ装置を設け、設備の存在の報知とその設備の方向への案内を行なう事を可能としていた。 On the other hand, a technique for detecting a wireless LAN radio wave arrival method is disclosed in Patent Document 1, and by combining these techniques, a wireless LAN device is provided in a facility to notify the presence of the facility and to guide the direction of the facility. It was possible to do.
しかしながら、上記の案内を行なう技術においては、設備の存在の報知とその設備への方向の案内が可能であっても、その設備が現在使用可能か（使用可能、一時的に使用不可、故障や保守などにより使用不能）または現在使用可能では無いが今後使用可能となるかという情報は提供されていない。また、例えば上記設備の状況をＳＳＩＤの内容を変更することにより提供したとしても、一般に無線ＬＡＮ機能を持つ端末装置においては、受信したＳＳＩＤを電波の強度が強い順に上位から表示する機能が一般的であり、ＳＳＩＤの内容で並び替えを行なえるものではないため、多数の設備からの設備の情報を効率的に検索することは困難であった。 However, in the technology for performing the above guidance, even if it is possible to notify the existence of the equipment and guide the direction to the equipment, is the equipment currently available (usable, temporarily unavailable, malfunction or No information is provided on whether it will be usable in the future, but it is not usable due to maintenance, etc., or is not currently usable. For example, even if the status of the equipment is provided by changing the contents of the SSID, a terminal device having a wireless LAN function generally has a function of displaying the received SSID from the top in descending order of radio wave strength. Since it is not possible to sort by the contents of the SSID, it is difficult to efficiently search for facility information from a large number of facilities.
本発明は上記の課題を解決するためになされたものであり、その目的は、無線ＬＡＮの電波を利用した設備案内装置において、簡易な方法でその設備の状況を伝達することを可能とする設備案内装置を提供することにある。 The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a facility guidance device using radio waves of a wireless LAN that can transmit the status of the facility in a simple manner. It is to provide a guide device.
上記の課題を解決するために、本発明は、無線ＬＡＮの電波を利用した設備案内装置において、案内対象の設備の状態によって前記無線ＬＡＮのビーコン電波の送信電力を変化させることを特徴とする。 In order to solve the above-described problems, the present invention is characterized in that, in an equipment guidance apparatus using radio waves of a wireless LAN, the transmission power of the beacon radio waves of the wireless LAN is changed according to the state of the equipment to be guided.
また、本発明は、前記案内対象の設備が使用できない場合は前記無線ＬＡＮの電波の送信を停止することを特徴とする。 In addition, the present invention is characterized in that transmission of the wireless LAN radio wave is stopped when the facility to be guided cannot be used.
また、本発明は、前記案内対象の設備が使用できるまでの時間が予測できる場合は前記無線ＬＡＮの電波の送信電力を所定の電力から前記設備が使用できるまでの時間まで上昇し続け、前記設備が使用できる時間には前記無線ＬＡＮの電波の送信電力を最大の電力とすることを特徴とする。 In the present invention, when it is possible to predict the time until the facility to be guided can be used, the radio LAN radio wave transmission power continues to increase from a predetermined power to the time until the facility can be used. When the wireless LAN can be used, the transmission power of the radio wave of the wireless LAN is set to the maximum power.
上記のように無線ＬＡＮ装置から送信する電波の強度を設備の状態に関連付けて設備の案内を行なうことにより、使用可能な設備は、無線ＬＡＮ機能を持つ端末装置のＳＳＩＤ一覧表示において現在位置から近い順により上位に表示され、存在するが現在利用できない設備はＳＳＩＤ一覧表示においてより下位に表示されることとなる。また、当面利用できない設備はＳＳＩＤ一覧には現れなくなる。 As described above, by guiding the facility by associating the intensity of the radio wave transmitted from the wireless LAN device with the state of the facility, the usable facility is close to the current position in the SSID list display of the terminal device having the wireless LAN function. The equipment that is displayed in the upper order in order and that is present but is not currently available will be displayed in the lower order in the SSID list display. Also, facilities that cannot be used for the time being do not appear in the SSID list.
本発明の設備案内装置をトイレやエレベーター等の状況によって使用できない、または使用可能となるまでに時間が掛かる可能性がある設備に設置して案内することにより、より近くでかつ待ち時間が少なく利用可能な設備を無線ＬＡＮ機能を有する端末装置を所持したユーザーに案内することが可能となる。 Use the equipment guidance device of the present invention closer to the equipment and with less waiting time by installing it in equipment that cannot be used depending on the situation such as toilets and elevators, or that may take time to become usable. It is possible to guide a possible facility to a user who possesses a terminal device having a wireless LAN function.
［実施例１］
本発明の実施例１における設備案内装置の動作について、図１を使用して説明する。
[Example 1]
Operation | movement of the equipment guidance apparatus in Example 1 of this invention is demonstrated using FIG.
図１は本発明の設備案内装置における設備の状態に応じた電波の強弱の変化を示すグラフである。通常案内を行なう対象の設備が利用可能である場合は、設備案内装置は最も強い送信電力で無線ＬＡＮのビーコン電波を送信している（時刻ＴＯ〜Ｔ１）。ここで、当該の設備に利用者が入り一時的に使用できない状態となった場合は、設備案内装置は所定の弱さの送信電力で無線ＬＡＮのビーコン電波を送信し、予め過去の利用状況で算出されている当該設備の平均利用時間（時刻Ｔ１〜Ｔ２）の間、徐々に送信電力を強めていく。当該設備が一時的に使用できない状態となった時間から平均利用時間が経過した後、または当該設備が再度利用可能になった時点で、設備案内装置は最も強い送信電力で無線ＬＡＮのビーコン電波を送信する（時速Ｔ２〜）。 FIG. 1 is a graph showing changes in strength of radio waves according to the state of equipment in the equipment guidance apparatus of the present invention. When the facility for which normal guidance is to be performed is available, the facility guidance device transmits a wireless LAN beacon radio wave with the strongest transmission power (time TO to T1). Here, when a user enters the equipment and becomes temporarily unavailable, the equipment guidance device transmits a wireless LAN beacon signal with a predetermined weak transmission power, The transmission power is gradually increased during the calculated average usage time (time T1 to T2) of the equipment. After the average usage time has elapsed since the time when the equipment was temporarily unavailable, or when the equipment becomes available again, the equipment guidance device transmits the wireless LAN beacon signal with the strongest transmission power. Transmit (speed T2-).
一方、当該設備がメンテナンスや清掃で利用できない状況が継続する状況となったときは、設備案内装置はビーコン電波の発射を停止する（時刻Ｔ３〜Ｔ４）。メンテナンスや清掃が完了し、当該設備が再度利用可能になった時点で、設備案内装置は最も強い電力で無線ＬＡＮのビーコン電波を発射する（時速Ｔ２〜）。 On the other hand, when the situation where the equipment cannot be used for maintenance or cleaning continues, the equipment guidance device stops emitting beacon radio waves (time T3 to T4). When the maintenance or cleaning is completed and the equipment becomes available again, the equipment guidance device emits a wireless LAN beacon radio wave with the strongest power (T2-speed per hour).
図２は上記の設備案内装置をトイレ等の設備Ａと設備Ｂとに導入した際の構成と電波の状況を表す図である。図２において、設備Ａには設備案内装置５が設置されており、設備案内装置５からは無線ＬＡＮのビーコン電波５ａが定期的に発射されている。また、同様に設備Ｂには設備案内装置６が設置されており、設備案内装置６からは無線ＬＡＮのビーコン電波６ａが定期的に発射されている。 FIG. 2 is a diagram showing a configuration and radio wave conditions when the above-described equipment guidance device is introduced into equipment A and equipment B such as a toilet. In FIG. 2, a facility guidance device 5 is installed in the facility A, and a wireless LAN beacon radio wave 5 a is periodically emitted from the facility guidance device 5. Similarly, an equipment guidance device 6 is installed in the equipment B, and a wireless LAN beacon radio wave 6 a is periodically emitted from the equipment guidance device 6.
ここで、設備Ａよりは設備Ｂに近い場所に位置する利用者３が、無線ＬＡＮ機能を有する端末４を使用して付近の無線ＬＡＮ機器の状況を表示した場合、利用者３はより設備Ｂに近く、設備Ｂの案内装置６からのビーコン電波６ａが設備Ａの案内装置５からのビーコン電波５ａよりも強いため、図３の端末装置４の画面４ａに示すように設備ＢのＳＳＩＤ１を含む案内が上位に表示される。このことにより利用者３は、設備Ｂはすぐ利用可能と判断し、設備Ｂに入り待ち時間無く利用することが可能となる。 Here, when the user 3 located closer to the facility B than the facility A displays the status of the nearby wireless LAN device using the terminal 4 having the wireless LAN function, the user 3 is more likely to install the facility B. Since the beacon radio wave 6a from the guidance device 6 of the facility B is stronger than the beacon radio wave 5a from the guidance device 5 of the equipment A, the SSID 1 of the equipment B is included as shown in the screen 4a of the terminal device 4 in FIG. The guidance is displayed at the top. As a result, the user 3 determines that the facility B can be used immediately, and can enter the facility B and use it without waiting time.
一方、図４に示すように、設備Ｂが他人に使用されている場合、設備案内装置６からの無線ＬＡＮのビーコン電波６ａは図１に示すように一時弱くなる。この状態においては、設備Ｂの案内装置６からのビーコン電波６ａが弱くなっているため、図５の端末装置４の画面４ｂに示すように、設備ＡのＳＳＩＤ２を含む案内が設備ＢのＳＳＩＤ１を含む案内より上位に表示される。このことにより利用者３は、設備Ａがすぐ利用可能と判断し、設備Ａを待ち時間無く利用することが可能となる。 On the other hand, as shown in FIG. 4, when the equipment B is used by another person, the beacon radio wave 6a of the wireless LAN from the equipment guidance device 6 temporarily becomes weak as shown in FIG. In this state, since the beacon radio wave 6a from the guidance device 6 of the facility B is weak, the guidance including the SSID 2 of the facility A changes the SSID 1 of the facility B as shown in the screen 4b of the terminal device 4 in FIG. It is displayed above the guidance that includes it. Accordingly, the user 3 determines that the facility A can be used immediately, and can use the facility A without waiting time.
また、設備Ｂが他人に使用されている状況においても、設備Ｂの平均利用時間が経過する頃には設備Ｂの案内装置６からのビーコン電波６ａが設備Ａの案内装置６からのビーコン電波６ａよりも再度強くなるため、利用者３は設備Ｂがもうすぐ利用可能と判断し、設備Ｂの前で待ち、より短い待ち時間で設備Ｂを利用することが可能となる。 Even when the equipment B is being used by another person, the beacon radio wave 6a from the guidance device 6 of the equipment B becomes the beacon radio wave 6a from the guidance device 6 of the equipment A when the average usage time of the equipment B elapses. Therefore, the user 3 determines that the facility B is available soon, waits in front of the facility B, and can use the facility B with a shorter waiting time.
このように、各設備の利用状況によって各設備案内装置からの無線ＬＡＮのビーコン電波の送信電力を変化させることにより、より効率的に各設備への案内を行なうことが可能となる。
［実施例２］
図６は上記の設備案内装置を昇降機Ａと昇降機Ｂとに導入した際の構成と電波の状況を表す図である。図６において、昇降機Ａには設備案内装置１５が設置されており、設備案内装置１５からは無線ＬＡＮのビーコン電波１５ａが定期的に発射されている。また、同様に昇降機Ｂには設備案内装置１６が設置されており、設備案内装置１６からは無線ＬＡＮのビーコン電波１６ａが定期的に発射されている。
In this way, by changing the transmission power of the wireless LAN beacon radio wave from each equipment guidance device according to the usage status of each equipment, it is possible to guide each equipment more efficiently.
[Example 2]
FIG. 6 is a diagram showing the configuration and the state of radio waves when the equipment guidance apparatus is introduced into the elevator A and the elevator B. In FIG. 6, an equipment guide device 15 is installed in the elevator A, and a beacon radio wave 15 a of a wireless LAN is periodically emitted from the equipment guide device 15. Similarly, the elevator B is provided with an equipment guide device 16, and wireless LAN beacon radio waves 16 a are periodically emitted from the equipment guide device 16.
ここで、昇降機Ａよりは昇降機Ｂに近い場所に位置する車椅子利用者３が、無線ＬＡＮ機能と技術文献１に示すような電波到達方向検知機能とを持つ端末装置１４を使用して付近の無線ＬＡＮ機器の状況を表示した場合、利用者３はより昇降機Ｂに近く、昇降機Ｂの案内装置１６からのビーコン電波１６ａが昇降機Ｂの案内装置１５からのビーコン電波１５ａよりも強いため、図７の端末装置１４の画面１４ａに示すように、昇降機ＢのＳＳＩＤ１を含む案内が上位に表示される。また、電波到達方向検知機能によりビーコン電波１６ａの到達方向を検知し、図７の端末装置１４の画面１４ａに示すように昇降機Ｂへの移動方向を表示することが可能となる。このことにより車椅子利用者１３は、昇降機Ｂはすぐ利用可能と判断し、昇降機Ｂの方向に向かい待ち時間無く利用することが可能となる。 Here, the wheelchair user 3 located closer to the elevator B than the elevator A uses a terminal device 14 having a wireless LAN function and a radio wave arrival direction detection function as shown in the technical literature 1, and the nearby wireless When the status of the LAN device is displayed, the user 3 is closer to the elevator B, and the beacon radio wave 16a from the guide device 16 of the elevator B is stronger than the beacon radio wave 15a from the guide device 15 of the elevator B. As shown on the screen 14a of the terminal device 14, the guidance including the SSID 1 of the elevator B is displayed at the upper level. Further, the arrival direction of the beacon radio wave 16a is detected by the radio wave arrival direction detection function, and the moving direction to the elevator B can be displayed as shown on the screen 14a of the terminal device 14 in FIG. Thus, the wheelchair user 13 determines that the elevator B can be used immediately, and can use the elevator B in the direction of the elevator B without waiting.
一方、図８に示すように、昇降機Ｂが他人に使用されている場合や別の階床に停止している場合、設備案内装置１６からの無線ＬＡＮのビーコン電波１６ａは一時弱くなる。この状態においては、昇降機Ｂの案内装置１６からのビーコン電波１６ａが弱くなっているため、図９の端末装置１４の画面１４ｂに示すように、昇降機ＡのＳＳＩＤ２を含む案内が設備ＢのＳＳＩＤ１を含む案内より上位に表示される。 On the other hand, as shown in FIG. 8, when the elevator B is used by another person or when it is stopped on another floor, the wireless LAN beacon radio wave 16 a from the facility guidance device 16 is temporarily weakened. In this state, since the beacon radio wave 16a from the guidance device 16 of the elevator B is weak, the guidance including the SSID 2 of the elevator A changes the SSID 1 of the equipment B as shown in the screen 14b of the terminal device 14 in FIG. It is displayed above the guidance that includes it.
このことにより車椅子利用者１３は、昇降機Ａの方がすぐ利用可能と判断し、昇降機Ａの方に向かい待ち時間無く利用することが可能となる。 Thus, the wheelchair user 13 determines that the elevator A can be used immediately, and can use the elevator 13 toward the elevator A without waiting.
また、昇降機Ｂが点検中や保守作業中で当面使用できない状況においては、昇降機Ｂの案内装置１６からのビーコン電波１６ａは停止するため、図１０の画面１４ｃに示すように昇降機ＡのＳＳＩＤ２を含む案内のみが表示される。 In addition, when the elevator B is in an inspection or maintenance operation and cannot be used for the time being, the beacon radio wave 16a from the guide device 16 of the elevator B is stopped, so the SSID 2 of the elevator A is included as shown in the screen 14c of FIG. Only guidance is displayed.
このことにより車椅子利用者１３は、昇降機Ａのみが利用可能と判断し、昇降機Ａの方向に向かい待ち時間無く利用することが可能となる。 As a result, the wheelchair user 13 determines that only the elevator A can be used, and moves toward the elevator A and can use it without waiting.
このように、各設備の利用状況によって各設備案内装置からの無線ＬＡＮのビーコン電波の送信電力を変化させることにより、より効率的に各設備への案内を行なうことが可能となる。 In this way, by changing the transmission power of the wireless LAN beacon radio wave from each equipment guidance device according to the usage status of each equipment, it is possible to guide each equipment more efficiently.
