Description

本発明は、測位機能を備えて緊急時にサービスセンターへ通報する携帯型緊急通報無線端末に関するものである。   The present invention relates to a portable emergency call radio terminal that has a positioning function and notifies a service center in an emergency.

昨今の児童誘拐対策として、測位機能を備える携帯型の緊急通報用途の無線端末を児童に携行させることが行われている。誘拐発生時には無線端末を児童に操作させて発報させ、測位結果をサービスセンターへ通報することで、誘拐発生の事実を地上の無線基地局を介してサービスセンターへ知らしめるのである。この類の代表例として、セコム社の提供するココセコム（R）システム（登録商標）や、ＮＴＴＤｏＣｏＭｏ社の提供するキッズケータイ（登録商標）（非特許文献１参照）などが挙げられる。   As a recent child kidnapping measure, a portable wireless terminal with a positioning function for carrying emergency calls is carried with children. When a kidnapping occurs, the child is operated by operating a wireless terminal, and the positioning result is reported to the service center, thereby informing the service center of the fact that the kidnapping has occurred via the ground wireless base station. Representative examples of this class include the Cocosecom (R) System (registered trademark) provided by Secom, and the Kids Keitai (registered trademark) provided by NTT DoCoMo (see Non-Patent Document 1).

ところが、このような緊急通報用途の無線端末の存在は既に広く知られているので、誘拐犯は誘拐計画時に、無線端末の機能を無力化することを考慮しているはずである。この無力化については、以下のように考察される。   However, since the existence of such a wireless terminal for emergency call is already widely known, the kidnapper should consider disabling the function of the wireless terminal when planning the kidnapping. This neutralization is considered as follows.

第１に、無線端末を児童から取り上げて破壊してしまうと、無線端末と地上の無線基地局およびサービスセンターとのあいだの定期確認通信が行われず、誘拐の事実を早々に把握されてしまうため、誘拐犯としては無線端末を破壊する可能性は高くない。   First, if a wireless terminal is picked up from a child and destroyed, regular confirmation communication between the wireless terminal and the ground wireless base station and service center will not be performed, and the fact of kidnapping will be grasped quickly. As a kidnapper, the possibility of destroying a wireless terminal is not high.

第２に、無線端末を児童から取り上げてその場付近に放置しておくことが考えられるが、この場合には、無線端末と地上の無線基地局およびサービスセンターとのあいだの定期確認通信によって、無線端末の位置が長時間変わらないことから、誘拐の事実を早々に把握されてしまうため、誘拐犯としては無線端末を放置する可能性は高くない。   Secondly, it is conceivable to pick up the wireless terminal from the child and leave it in the vicinity, but in this case, by the periodic confirmation communication between the wireless terminal and the ground wireless base station and service center, Since the position of the wireless terminal does not change for a long time, the fact of the kidnapping is quickly grasped, so that the possibility of leaving the wireless terminal as a kidnapper is not high.

第三に、無線端末を児童から取り上げてその場付近で電源を切ってしまうことが考えられる。いかに緊急通報用途の無線端末といえども、病院内や飛行機搭乗時には電源を切らざるを得ず、このため、無線端末は電源を切ることが可能である。   Third, it is conceivable that the wireless terminal is picked up from a child and turned off near the spot. Even if it is a radio terminal for emergency call use, the power must be turned off at the time of hospital or boarding an airplane, so that the radio terminal can be turned off.

以上の考察から、誘拐犯は、第三の方法、すなわち無線端末を児童から取り上げてその場付近で電源を切ろうとする可能性が高い。しかし、ここで無線端末の電源をオフする操作に個人認証のセキュリティがかかっているとすれば、誘拐犯は、面倒な電源オフ操作に時間を費やすよりも、電池（充電池）を引き抜いた方が手早い上、サービスセンターへの発報の危険性も低いと判断するであろう。そこで、誘拐犯が無線端末を児童から取り上げても、その電源を容易には切られないようにする仕組みが必要であり、特に電池（充電池）の引き抜きの対策を施しておくことが重要である。なお、本発明に関連するものとして、特許文献１には、予備の非接触型給電バッテリーを内蔵するレンタル式のデジタルカメラに関する盗難防止技術に係る発明が開示されてある。
特開２０００―１５５８７８公報（請求項１１） ＮＴＴＤｏＣｏＭｏ社キッズケータイ掲載ホームページ（http://www.kids-keitai.com） From the above consideration, the kidnapper is likely to try the third method, that is, take the wireless terminal from the child and turn off the power near the spot. However, if security for personal authentication is applied to the operation of turning off the power of the wireless terminal, the kidnapper pulls out the battery (rechargeable battery) rather than spending time on the troublesome power-off operation. Will be quick and the risk of reporting to the service center will be low. Therefore, even if a kidnapper picks up a wireless terminal from a child, a mechanism is required to prevent the power from being easily turned off, and it is particularly important to take measures to remove the battery (rechargeable battery). is there. As related to the present invention, Patent Document 1 discloses an invention related to an anti-theft technology relating to a rental digital camera incorporating a spare non-contact power supply battery.
JP 2000-155878 A (Claim 11) NTT DoCoMo website for kids' mobile phones (http://www.kids-keitai.com)

非特許文献１を参照して閲覧可能なる、ＮＴＴＤｏＣｏＭｏ社の提供するキッズケータイ（Ｒ）（品番ＳＡ８００ｉ）においては、電池（充電池）を引き抜かれる場合の対策として、専用ネジで電池パックを固定し、第三者が故意に電池パックを外せないように工夫されてある。しかし、専用ネジとはいえども、それに見合った専用ドライバを誘拐犯が自作すれば、電池パックは簡単に外されてしまう。   In the Kids Mobile Phone (R) (part number SA800i) provided by NTT DoCoMo, which can be viewed with reference to Non-Patent Document 1, the battery pack is fixed with a special screw as a countermeasure when the battery (rechargeable battery) is pulled out. It is devised so that a third party cannot intentionally remove the battery pack. However, even if it is a dedicated screw, if the kidnapper makes a dedicated driver corresponding to it, the battery pack can be easily removed.

一方、特許文献１によれば、このデジタルカメラに搭載された盗難防止装置は、撮影用の通常用途の第１電源と、ＧＰＳ機能を有し所定エリア外に位置するものと自主判断した場合警報を発する非常時用の第２電源という、２つの電源装置を具備し、契約エリア範囲外に持ち出されようとするときに警報を発するものである。しかし、これに使用される２つの電源は、ともにハウジング内部に隠蔽される非接触型給電バッテリーであり、本願発明者らが危惧する誘拐犯にとっては、（ホットナイフなど解体用途工具を用いて）ハウジングをいったん開けることに成功したら、２つのバッテリーの両方が取り出されてしまい、デジタルカメラに搭載された盗難防止装置、いいかえると本願における緊急通報無線端末は、完全に無力化してしまう。   On the other hand, according to Patent Document 1, an alarm is provided when it is determined that the anti-theft device mounted on this digital camera has a first power source for normal use for photography and a GPS function and is located outside a predetermined area. It is equipped with two power supply devices, ie, a second power supply for emergencies that issues a warning, and issues an alarm when it is about to be taken out of the contract area. However, the two power sources used for this are non-contact type power supply batteries concealed inside the housing, and for the kidnappers who are concerned about the present inventors (using a tool for dismantling such as a hot knife) Once the housing is successfully opened, both the two batteries are removed, and the antitheft device mounted on the digital camera, in other words, the emergency call wireless terminal in the present application is completely disabled.

本発明は、そのような問題点を解決しようとしたものであり、その目的とするところは、誘拐犯など第三者が専用工具などを自作して故意に充電池を取り外しても、依然として電源を供給し続けることが可能な携帯型緊急通報無線端末を提供することにある。   The present invention is intended to solve such problems, and the purpose of the present invention is that even if a third party such as a kidnapper makes a dedicated tool or the like and intentionally removes the rechargeable battery, the power source still remains. It is to provide a portable emergency call radio terminal capable of continuing to supply a mobile phone.

上記問題点を解決するため、請求項１にあっては、ハウジングの内部空間に充電池を収納する第１の電池収納室と、この第１の電池収納室を隠蔽する底面を有して別の充電池を収納する第２の電池収納室とを設けるとともに、第２の電池収納室に収納される別の充電池を、電力供給を行わず一対の接続端子を具備するダミー充電池として、この別の充電池の接続先であるダミー端子を設けたことを特徴とする。   In order to solve the above-described problems, the present invention has a first battery storage chamber for storing a rechargeable battery in an internal space of the housing and a bottom surface for concealing the first battery storage chamber. A second battery storage chamber for storing the rechargeable battery and another rechargeable battery stored in the second battery storage chamber as a dummy rechargeable battery having a pair of connection terminals without supplying power, A dummy terminal as a connection destination of the other rechargeable battery is provided.

請求項２にあっては、請求項１の携帯型緊急通報無線端末において、別の充電池は、その一対の接続端子間が該別の充電池の内部で導通又は抵抗成分を介して接続されており、端末制御部は、ダミー端子を介して、別の充電池の一対の接続端子間に電気信号を印加し、この印加した電気信号の応答信号として所定の応答信号を受けたときには、別の充電池の一対の接続端子がダミー端子に接続されている状態であると判断する一方、所定の応答信号が得られず断線状態であると検知した場合には、別の充電池の一対の接続端子がダミー端子から離脱している状態であると判断して、無線通信部を介して地上の無線基地局へ異常発生の旨の無線発報を行うことを特徴とする。   According to claim 2, in the portable emergency call radio terminal according to claim 1, the other rechargeable battery is connected between the pair of connection terminals inside the other rechargeable battery through a conduction or resistance component. The terminal control unit applies an electrical signal between the pair of connection terminals of another rechargeable battery via the dummy terminal, and receives a predetermined response signal as a response signal of the applied electrical signal. On the other hand, if it is determined that the pair of connection terminals of the rechargeable battery is connected to the dummy terminal, and a predetermined response signal is not obtained and the disconnection state is detected, It is determined that the connection terminal is detached from the dummy terminal, and radio notification is made to the effect that an abnormality has occurred to a radio base station on the ground via the radio communication unit.

また、請求項３によれば、ハウジングの内部空間に充電池を収納する第１の電池収納室と、この第１の電池収納室を隠蔽する底面を有して別の充電池を収納する第２の電池収納室とを設けるとともに、第２の電池収納室に収納される別の充電池を、第１の電池収納室に収納される充電池と同様に電力供給を行い一対の接続端子を具備するスペア充電池として、この別の充電池の一対の接続端子の接続先であるスペア充電池接続端子を設け、このスペア充電池接続端子は、第１の電池収納室に収納される充電池と同様に、測位電波受信部と無線通信部と端末制御部と表示部とに電源供給が可能なように、電源供給路に接続されていることを特徴とする。   According to the third aspect of the present invention, the first battery storage chamber for storing the rechargeable battery in the internal space of the housing and the bottom surface for concealing the first battery storage chamber to store another rechargeable battery. And a pair of connection terminals for supplying power to another rechargeable battery stored in the second battery storage chamber in the same manner as the rechargeable battery stored in the first battery storage chamber. As a spare rechargeable battery, a spare rechargeable battery connection terminal which is a connection destination of a pair of connection terminals of the other rechargeable battery is provided, and the spare rechargeable battery connection terminal is a rechargeable battery stored in the first battery storage chamber. In the same manner as described above, the positioning radio wave receiving unit, the wireless communication unit, the terminal control unit, and the display unit are connected to a power supply path so that power can be supplied.

請求項４によれば、請求項３の携帯型緊急通報無線端末において、端末制御部は、スペア充電池接続端子を介して、一対の接続端子に印加されている電圧値を読み取り、この読み取った電圧値として所定の電圧値が得られたときに、別の充電池の一対の接続端子がスペア充電池接続端子に接続されている状態であると判断する一方、所定の電圧値が得られない場合には、別の充電池の一対の接続端子がスペア充電池接続端子から離脱している状態であると判断して、無線通信部を介して地上の無線基地局へ異常発生の旨の無線発報を行うことを特徴とする。   According to claim 4, in the portable emergency call radio terminal according to claim 3, the terminal control unit reads the voltage value applied to the pair of connection terminals via the spare rechargeable battery connection terminal and reads the voltage value. When a predetermined voltage value is obtained as the voltage value, it is determined that the pair of connection terminals of another rechargeable battery is connected to the spare rechargeable battery connection terminal, while the predetermined voltage value cannot be obtained. In such a case, it is determined that the pair of connection terminals of the other rechargeable battery is detached from the spare rechargeable battery connection terminal, and the wireless communication unit notifies the wireless base station on the ground that an abnormality has occurred. It is characterized by issuing a notification.

請求項１の構成によれば、第１の電池収納室に正規の充電池を収納しておき、第１の電池収納室を隠蔽する第２の電池収納室にはダミー充電池を収納しておくことで、悪意の第三者が目視可能な充電池（実はダミー充電池）を引き抜いて取り外したとしても、第２の電池収納室の底面で隠蔽された第１の電池収納室には正規の充電池を収納してあるので、この携帯型緊急通報無線端末ならば、誘拐犯など第三者にさとられずに依然として第１の電池収納室の充電池から電源の供給を受けることができる。すなわち、誘拐犯など悪意の第三者にとっては、目視可能な充電池を引き抜いて当該無線端末の無効化に成功したと判断する。ところが、引き抜いたのはダミー充電池であり、誘拐犯など悪意の第三者は、もはやそれ以上の電源の存在を追及しないはずである。而して、第１の電池収納室に収納した正規の充電池は、第２の電池収納室の底面にさえぎられて、誘拐犯など悪意の第三者に正規の充電池の存在をさとられることはない。   According to the configuration of claim 1, a regular rechargeable battery is stored in the first battery storage chamber, and a dummy rechargeable battery is stored in the second battery storage chamber that conceals the first battery storage chamber. Therefore, even if a malicious third party pulls out and removes a rechargeable battery (in fact, a dummy rechargeable battery), the first battery storage room concealed on the bottom surface of the second battery storage room Since this rechargeable battery is housed, the portable emergency call wireless terminal can still receive power from the rechargeable battery in the first battery compartment without being caught by a third party such as a kidnapper. . That is, for a malicious third party such as a kidnapper, it is determined that the wireless terminal has been successfully invalidated by pulling out the rechargeable battery. However, it was a dummy rechargeable battery that was pulled out, and malicious third parties such as kidnappers would no longer pursue the existence of further power sources. Thus, the regular rechargeable battery stored in the first battery storage chamber is blocked by the bottom surface of the second battery storage chamber, and the malicious rechargeable battery such as a kidnapper can take the presence of the regular rechargeable battery. There is nothing.

特に請求項２の構成によれば、ダミー充電池である別の充電池が引き抜かれてしまうと、別の充電池の一対の接続端子と、ダミー端子との接続が断たれ、導通状態でなくなって開放状態つまり断線状態になってしまい、これを検知した端末制御部は、無線通信部を介して地上の無線基地局へ異常発生の旨の無線発報を行うので、地上の無線基地局にとどまらず所定のサービスセンターに通報転送先を予め設定しておけば、地上の無線基地局経由で地上の有線無線の通信網を経由して、所定の通報先たる所定のサービスセンターに知らしめることも可能になる。   Particularly, when another rechargeable battery that is a dummy rechargeable battery is pulled out, the connection between the pair of connection terminals of the other rechargeable battery and the dummy terminal is disconnected, and the conductive state is lost. The terminal control unit that detects this is in an open state, i.e., a disconnection state, and performs radio notification to the ground radio base station via the radio communication unit. Notify the specified service center in advance and notify the specified service center as the specified report destination via the ground wireless base station via the ground wired wireless communication network. Is also possible.

請求項３の構成によれば、上述の請求項１と同様の効果が得られる以外にも、別の充電池が第１の電池収納室に収納される正規の充電池と同様に電力供給を行うスペア充電池であるので、この別の充電池が引き抜かれるまでは、電源供給源が２つ存在することになり、バックアップ電源をひとつ備えたことと等しく、作動時間がその分長くなる。   According to the configuration of the third aspect, in addition to the same effect as that of the first aspect described above, power can be supplied in the same manner as a normal rechargeable battery in which another rechargeable battery is accommodated in the first battery accommodating chamber. Since it is a spare rechargeable battery, there are two power supply sources until this other rechargeable battery is pulled out, which is equivalent to having one backup power supply, and the operation time is increased accordingly.

特に請求項４の構成によれば、スペア充電池である別の充電池が引き抜かれてしまうと、別の充電池の一対の接続端子と、スペア充電池接続端子との接続が断たれ、導通状態でなくなって開放状態つまり断線状態になってしまい、これを検知した端末制御部は、無線通信部を介して地上の無線基地局へ異常発生の旨の無線発報を行うので、地上の無線基地局にとどまらず所定のサービスセンターに通報転送先を予め設定しておけば、地上の無線基地局経由で地上の有線無線の通信網を経由して、所定の通報先たる所定のサービスセンターに知らしめることも可能になる。   In particular, according to the configuration of claim 4, if another rechargeable battery that is a spare rechargeable battery is pulled out, the connection between the pair of connection terminals of the other rechargeable battery and the spare rechargeable battery connection terminal is cut off, and conduction Since the terminal control unit that has detected this state is in an open state, i.e., a disconnection state, sends a radio notification to the ground radio base station via the radio communication unit that an abnormality has occurred. If you set up a notification forwarding destination in a predetermined service center in addition to the base station, you can connect to a predetermined service center that is a predetermined notification destination via a ground wireless base station and a wired wireless communication network. You can also let them know.

以下に、本発明に係る携帯型緊急通報無線端末の実施例を説明する。
実施例１は、請求項１と２を説明するものであり、実施例２は、請求項３と４を説明するものである。 Examples of the portable emergency call radio terminal according to the present invention will be described below.
The first embodiment explains claims 1 and 2, and the second embodiment explains claims 3 and 4.

図１は、携帯型緊急通報無線端末の分解斜視図であり、図２はダミー充電池の内部接続構造を表した模式図である。図３は、図１の各部品を組み立てた状態の斜視図である。図４は、携帯型緊急通報無線端末の外観構成を示す図である。   FIG. 1 is an exploded perspective view of a portable emergency call radio terminal, and FIG. 2 is a schematic diagram showing an internal connection structure of a dummy rechargeable battery. FIG. 3 is a perspective view showing a state in which the components shown in FIG. 1 are assembled. FIG. 4 is a diagram showing an external configuration of a portable emergency call radio terminal.

携帯型緊急通報無線端末１００のハウジングＨは、図１に示すように、操作入力部３０などが露出する前面ハウジングＨａと、裏蓋Ｈｃが着脱自在に取り付けられる背面ハウジングＨｂとから成っている。これら前面ハウジングＨａと背面ハウジングＨｂとによってできる内部空間Ｓには、充電池６０を収納する第１の電池収納室Ｖ１が形成されている。この第１の電池収納室Ｖ１は、プリント配線板９０上の背面ハウジングＨｂ側に敷かれた絶縁シート材（不図示）に充電池６０を収納するスペースを設けた構造で、プリント配線板９０上の他の部品との物理的接触を避けるために絶縁性の仕切りＶ１ａが形成されている。   As shown in FIG. 1, the housing H of the portable emergency call radio terminal 100 includes a front housing Ha from which the operation input unit 30 and the like are exposed, and a rear housing Hb to which a back cover Hc is detachably attached. A first battery storage chamber V1 for storing the rechargeable battery 60 is formed in the internal space S formed by the front housing Ha and the rear housing Hb. The first battery storage chamber V1 has a structure in which a space for storing the rechargeable battery 60 is provided in an insulating sheet material (not shown) laid on the back housing Hb side on the printed wiring board 90. An insulating partition V1a is formed to avoid physical contact with other components.

また、充電池６０の電源供給コネクタ６０ａの接続先として、電源受給コネクタ９０ｂが配設されている。なお、上述したダミー端子９０ａも、プリント配線板９０上の背面ハウジングＨｂ側に配設されてあり、測位電波受信部１０（後述）と無線通信部２０（後述）と報知音発生部５０（後述）と充電池６０と端末制御部８０（後述）とは、プリント配線板９０上の背面ハウジングＨｂ側の面のうち仕切りＶ１ａ以外の実装部分と、プリント配線板９０上の前面ハウジングＨａとに実装されており（不図示）、これらの部品はハウジングＨ内に保持されている。
別の充電池７０は、一対の接続端子７０ａを具備するが、電力供給は行わないダミー充電池であり、その一対の接続端子７０ａは、携帯型緊急通報無線端末１００の奥に配置されたプリント配線板９０（図１参照）に設けられたダミー端子９０ａと接続され、一目すれば、あたかも正規の電源供給電池のように見えるように構成されている。このプリント配線板９０には、測位電波受信部１０、無線通信部２０、報知音発生部５０、充電池６０、端末制御部８０等が、電気回路として接続されている。 Further, a power supply connector 90b is provided as a connection destination of the power supply connector 60a of the rechargeable battery 60. The dummy terminal 90a described above is also disposed on the rear housing Hb side on the printed wiring board 90, and includes a positioning radio wave receiving unit 10 (described later), a wireless communication unit 20 (described later), and a notification sound generating unit 50 (described later). ), The rechargeable battery 60, and the terminal control unit 80 (described later) are mounted on the mounting portion other than the partition V1a on the rear housing Hb side surface on the printed wiring board 90 and the front housing Ha on the printed wiring board 90. These parts are held in the housing H (not shown).
Another rechargeable battery 70 is a dummy rechargeable battery that includes a pair of connection terminals 70 a but does not supply power. The pair of connection terminals 70 a is a print disposed at the back of the portable emergency call radio terminal 100. It is connected to a dummy terminal 90a provided on the wiring board 90 (see FIG. 1). At first glance, it is configured to look like a regular power supply battery. To this printed wiring board 90, a positioning radio wave receiving unit 10, a wireless communication unit 20, a notification sound generating unit 50, a rechargeable battery 60, a terminal control unit 80, and the like are connected as an electric circuit.

なお、操作入力部３０と表示部４０は、図４に示したような配設箇所に取り付けられ、図１には前面ハウジングＨａと背面ハウジングＨｂとの接合部にで発報ボタン３０ａが挟持されて保持される構造とされ、外部接続コネクタ（不図示）を不用時には隠す弾性カバーＣも又、前面ハウジングＨａと背面ハウジングＨｂとの接合部で開閉自在に挟持され保持されている。   The operation input unit 30 and the display unit 40 are attached to the locations as shown in FIG. 4. In FIG. 1, a notification button 30a is sandwiched between the joints of the front housing Ha and the rear housing Hb. The elastic cover C that is configured to be held and that conceals the external connection connector (not shown) when not in use is also held and held in a freely openable / closable manner at the joint between the front housing Ha and the rear housing Hb.

また、背面ハウジングＨｂには第１の電池収納室Ｖ１を隠蔽する底面１１を有して別の充電池７０を収納する第２の電池収納室Ｖ２が形成されてある。この第２の電池収納室Ｖ２は、従来の携帯型緊急通報無線端末における正規の充電池６０の収納室に著しく類似させた形状を有している。なお、図１では、第１の電池収納室Ｖ１は、第２の電池収納室Ｖ２よりもスペースが狭くなっているが、本発明はこの例には限られない。すなわち、第１の電池収納室Ｖ１のスペースは、プリント配線板９０に載置する電子部品のスペースに影響されるのであり、第２の電池収納室Ｖ２と同じ大きさのスペースや、それより大きなスペースを確保するようにしてもよい。   The rear housing Hb has a bottom surface 11 that conceals the first battery storage chamber V1 and a second battery storage chamber V2 that stores another rechargeable battery 70 therein. The second battery storage room V2 has a shape remarkably similar to the storage room of the regular rechargeable battery 60 in the conventional portable emergency call radio terminal. In FIG. 1, the first battery storage chamber V1 is narrower than the second battery storage chamber V2, but the present invention is not limited to this example. That is, the space of the first battery storage chamber V1 is affected by the space of the electronic components placed on the printed wiring board 90, and is the same size as the second battery storage chamber V2 or larger than that. Space may be secured.

この底面１１のうち、ダミー端子９０ａに対向する箇所には、ダミー端子９０ａが丁度覗く程度の大きさのダミー端子露出孔Ｖ２ａが開けられて、前面ハウジングＨａと背面ハウジングＨｂとを組み立てると、ダミー端子９０ａがダミー端子露出孔Ｖ２ａから覗き、一対の接続端子７０ａを手で着脱できるようになっている。   A dummy terminal exposure hole V2a large enough to be seen through the dummy terminal 90a is opened at a position of the bottom surface 11 facing the dummy terminal 90a. The terminal 90a can be seen through the dummy terminal exposure hole V2a, and the pair of connection terminals 70a can be attached and detached by hand.

さらに、底面１１には、携帯型緊急通報無線端末１００の商品名や商品ナンバーバーコードや製造年月日が書かれたラベルＬが貼付されてあり、これにより、底面１１よりも内部にはもはや手では簡単に着脱できそうにない部品ばかりが内装されているように見える構造にしている。   Furthermore, a label L on which the product name, product number bar code, and date of manufacture of the portable emergency call radio terminal 100 are affixed is attached to the bottom surface 11. It is structured so that only parts that cannot be easily attached and detached by hand appear to be installed.

別の充電池７０から延出するリード線の先には一対の接続端子７０ａが配設され、その内部では、図２に示すように、一対の接続端子７０ａの両端子間が抵抗成分Ｒを介して接続されており、一対の接続端子７０ａの両端子間に電気信号を印加すると抵抗成分Ｒで減衰された信号成分が出力されるようになっている。なお、抵抗成分Ｒの値は、出力したい信号成分の期待する振幅値に応じて設計すればよく、単に金属線により導通状態になっているだけでもよい。   A pair of connection terminals 70a is disposed at the tip of a lead wire extending from another rechargeable battery 70, and inside the pair, as shown in FIG. When an electric signal is applied between both terminals of the pair of connection terminals 70a, a signal component attenuated by the resistance component R is output. Note that the value of the resistance component R may be designed according to the expected amplitude value of the signal component to be output, or may simply be in a conductive state with a metal wire.

このような携帯型緊急通報無線端末１００の組み立て構造について説明する。図４のうち、携帯型緊急通報無線端末１００のハウジングＨの背面図には、裏蓋Ｈｃを描画している。従来の携帯型緊急通報無線端末では、この裏蓋Ｈｃを外せば、すぐに正規の充電池６０が見え、これを取り外せるようになっている。   The assembly structure of such a portable emergency call radio terminal 100 will be described. In FIG. 4, the back cover Hc is drawn on the rear view of the housing H of the portable emergency call radio terminal 100. In the conventional portable emergency call radio terminal, when the back cover Hc is removed, the regular rechargeable battery 60 can be seen immediately and can be removed.

以上のような組み立て構造を以って、予め充電池６０を第１の電池収納室Ｖ１に収納させた状態で、電源供給コネクタ６０ａを電源受給コネクタ９０ｂに接続し（このとき、図４に例示する電源入切ボタン３０ｂは操作されていないので、携帯型緊急通報無線端末１００は内部導電していない）、このプリント配線板９０を、発報ボタン３０ａと弾性カバーＣとともに、前面ハウジングＨａと背面ハウジングＨｂとで挟持するよう、組み合わせて互いに嵌め込む。このときの前面ハウジングＨａと背面ハウジングＨｂとの係合構造については、凹凸爪嵌め合わせ等周知の接続構造でかまわず、説明を省略する。   With the assembly structure as described above, the power supply connector 60a is connected to the power supply connector 90b in a state where the rechargeable battery 60 is previously stored in the first battery storage chamber V1 (in this case, as illustrated in FIG. 4). Since the power-on / off button 30b to be operated is not operated, the portable emergency call radio terminal 100 is not electrically conductive), and the printed wiring board 90, together with the alarm button 30a and the elastic cover C, are connected to the front housing Ha and the rear surface. They are combined and fitted together so as to be sandwiched between the housings Hb. The engagement structure between the front housing Ha and the rear housing Hb at this time may be a well-known connection structure such as a concavo-convex nail fitting, and the description thereof is omitted.

そして、前面ハウジングＨａと背面ハウジングＨｂとが係合すれば、ダミー端子９０ａがダミー端子露出孔Ｖ２ａから覗き、この状態で別の充電池７０を第２の電池収納室Ｖ２に収納載置すると、図３のような状態となり、一対の接続端子７０ａをダミー端子９０ａへ嵌め込んで、裏蓋Ｈｃを取り付ければ、携帯型緊急通報無線端末１００が組み上がる。裏蓋Ｈｃは、従来と同様の形状として、手指により特に苦労せずに取り外せるようにしておく。これは、誘拐犯が、裏蓋Ｈｃを取り外せないために、携帯型緊急通報無線端末１００を破壊してしまうような事態を防止するための配慮である。   Then, if the front housing Ha and the rear housing Hb are engaged, the dummy terminal 90a is viewed from the dummy terminal exposure hole V2a, and another rechargeable battery 70 is stored and placed in the second battery storage chamber V2 in this state. When the pair of connection terminals 70a are fitted into the dummy terminals 90a and the back cover Hc is attached, the portable emergency call radio terminal 100 is assembled. The back cover Hc has a shape similar to that of the conventional case so that it can be removed with fingers without any particular difficulty. This is a consideration for preventing the kidnapper from destroying the portable emergency call radio terminal 100 because the back cover Hc cannot be removed.

この状態で電源入切ボタン３０ｂ（図４参照）を操作すれば、電源オンとなり、携帯型緊急通報無線端末１００の動作が開始する。勿論、電源は充電池６０から供給される。なお、電源オンの直後には、測位電波受信部１０と無線通信部２０と端末制御部８０とのいずれかに記憶されていた測位に関する情報を更新すべく、起動時に測位情報（アルマナックやエフェメリス）の有効期限を確認し、必要に応じてデータの初期化を行う。この工程は、所謂ホットスタートやコールドスタートなどＧＰＳに付随する仕様に応じて、行えばよい。   When the power on / off button 30b (see FIG. 4) is operated in this state, the power is turned on and the operation of the portable emergency call radio terminal 100 is started. Of course, the power is supplied from the rechargeable battery 60. Immediately after the power is turned on, the positioning information (almanac or ephemeris) at the time of activation is updated to update the information related to the positioning stored in any of the positioning radio wave reception unit 10, the wireless communication unit 20, and the terminal control unit 80. Confirm the expiration date and initialize the data if necessary. This step may be performed according to specifications accompanying GPS such as so-called hot start and cold start.

その後、更に、端末制御部８０は、プリント配線板９０に設けられたダミー端子９０ａの導通状態を監視することで、別の充電池７０の一対の接続端子７０ａがダミー端子９０ａと接続しているか否かを検知する。このため、端末制御部８０は、ダミー端子９０ａに電気信号を印加するよう、信号出力が可能になっている。より具体的には、ダミー端子９０ａを介して、別の充電池７０の一対の接続端子７０ａの両端子間に電気信号を印加し、この印加した電気信号の応答信号として所定の応答信号が得られれば、別の充電池７０の一対の接続端子７０ａがダミー端子９０ａと接続している状態であると判断して、特段の動作は行わないが、所定の応答信号が得られない場合は、別の充電池７０の一対の接続端子７０ａがダミー端子９０ａから離脱している状態であると判断して、無線通信部２０を介して地上の無線基地局３００へ異常発生を通知する無線発報を行う。この端末制御部８０によるダミー端子９０ａの導通状態の監視動作は、定期的に行ってもよいし、何か操作入力がなされた都度であってもよい。   Thereafter, the terminal control unit 80 further monitors whether the dummy terminal 90a provided on the printed wiring board 90 is in a conductive state, so that a pair of connection terminals 70a of another rechargeable battery 70 is connected to the dummy terminal 90a. Detect whether or not. Therefore, the terminal control unit 80 can output a signal so as to apply an electric signal to the dummy terminal 90a. More specifically, an electrical signal is applied between both terminals of a pair of connection terminals 70a of another rechargeable battery 70 via a dummy terminal 90a, and a predetermined response signal is obtained as a response signal of the applied electrical signal. If it is determined that the pair of connection terminals 70a of the other rechargeable battery 70 is connected to the dummy terminal 90a, no special operation is performed, but a predetermined response signal cannot be obtained. It is determined that the pair of connection terminals 70a of the other rechargeable battery 70 is detached from the dummy terminal 90a, and the wireless notification that notifies the ground wireless base station 300 of the occurrence of abnormality via the wireless communication unit 20 I do. The operation of monitoring the conduction state of the dummy terminal 90a by the terminal control unit 80 may be performed periodically or whenever an operation input is made.

なお、一対の接続端子７０ａがダミー端子９０ａから離脱している場合には、表示部４０と報知音発生部５０の作動によって、携帯型緊急通報無線端末１００が動作していることが操作者に知られないようにするために、端末制御部８０の制御によってこれら２つを動作停止させることが望ましい。そうすれば、誘拐犯を刺激することがないので、サービスセンター経由での近時間内の誘拐犯逮捕につながる。   When the pair of connection terminals 70a is detached from the dummy terminal 90a, it is indicated to the operator that the portable emergency call radio terminal 100 is operated by the operation of the display unit 40 and the notification sound generation unit 50. In order not to be known, it is desirable to stop these two operations under the control of the terminal control unit 80. This will not stimulate the kidnapper, leading to the arrest of the kidnapper in the near future via the service center.

図５は、携帯型緊急通報無線端末およびこの端末と連携する監視通報システムについてあらわした全体概要図であり、図６は携帯型緊急通報無線端末の基本動作について説明するフローチャートである。   FIG. 5 is an overall schematic diagram showing a portable emergency call wireless terminal and a monitoring / reporting system linked to this terminal, and FIG. 6 is a flowchart for explaining the basic operation of the portable emergency call wireless terminal.

携帯型緊急通報無線端末１００は、図５に示すように、測位電波受信部１０と、無線通信部２０と、操作入力部３０と、表示部４０と、報知音発生部５０と、充電池６０と、別の充電池７０と、端末制御部８０とを備えて構成されている。   As shown in FIG. 5, the portable emergency call radio terminal 100 includes a positioning radio wave reception unit 10, a radio communication unit 20, an operation input unit 30, a display unit 40, a notification sound generation unit 50, and a rechargeable battery 60. And another rechargeable battery 70 and a terminal control unit 80.

測位電波受信部１０は、測位用の無線電波を受信するための電波受信部であり、図１に示すように地球衛星周回軌道を移動する複数のGPS（Global
Positioning System）衛星２００からの電波を受信するものである。ただし、GPS衛星２００からの電波を捕捉できない状況では、GPS衛星電波の代わりに地上テレビ波や携帯電話用の無線基地局３００からの電波を受信し、この場合、後述する無線通信部２０に受信機能を代行依存する。 The positioning radio wave receiving unit 10 is a radio wave receiving unit for receiving positioning radio waves, and as shown in FIG. 1, a plurality of GPS (Global
Positioning System) Receives radio waves from the satellite 200. However, in a situation where the radio wave from the GPS satellite 200 cannot be captured, a radio wave from the terrestrial TV wave or the mobile phone radio base station 300 is received instead of the GPS satellite radio wave. In this case, the radio communication unit 20 described later receives the radio wave. Relying on functionality

無線通信部２０は、一般の携帯電話機と同様に、地上の無線基地局３００との間でPDC方式（Personal
Digital Cellular system）の無線通信を行う通信部である。勿論、PDC方式でなくてPHS（Personal Handy phone System）方式の無線通信を行う通信部であってもよい。 The wireless communication unit 20 is connected to the ground wireless base station 300 in the same manner as a general mobile phone.
This is a communication unit that performs wireless communication of the Digital Cellular system). Of course, it may be a communication unit that performs wireless communication using the PHS (Personal Handy phone System) system instead of the PDC system.

操作入力部３０は、図４、図５に示しているように、操作表面に設けられたボタン群を具備し、少なくとも、緊急時の発報操作入力と電源入切の操作入力とを受け付けるものである。この操作入力部３０を構成するボタン群としては、緊急時の発報操作入力を受け付けるための１乃至複数の発報ボタン３０ａ（図５では外面の両側面に２つ）と、電源入切の操作入力を受け付けるための１つの電源入切ボタン３０ｂと、緊急時ではないが無事であることを携行者の意思で自発的に無線連絡する操作入力（今から帰宅する旨などの操作入力）を受け付けるための１つの通知ボタン３０ｃとを備えて構成されている。勿論、ボタン群の構成は、これに限るものではなく、少なくとも、緊急時の発報操作入力と電源入切の操作入力とを受け付けるものであればボタン群の数および形態は問わない。   As shown in FIGS. 4 and 5, the operation input unit 30 includes a group of buttons provided on the operation surface, and accepts at least an emergency alert operation input and a power on / off operation input. It is. The button group constituting the operation input unit 30 includes one or more alarm buttons 30a (two on both sides of the outer surface in FIG. 5) for receiving an emergency alarm operation input, One power on / off button 30b for accepting an operation input, and an operation input (an operation input for returning home, etc.) for voluntary wireless communication with the intention of the carrier to be safe but not in an emergency. And one notification button 30c for receiving. Of course, the configuration of the button group is not limited to this, and the number and form of the button group are not limited as long as they receive at least an emergency alert operation input and a power on / off operation input.

表示部４０は、操作入力部３０と同様に、動作中であることを表すため、LED等の発光素子群を備えて構成されている。この表示部４０を構成する発光素子群としては、無線通信部２０が地上の無線基地局３００との間で通信中であることを示すための通信状態表示用発光素子４０ａと、後述する充電池６０の電池残量を発光色表示で多段階に表すための電池残量表示用発光素子４０ｂと、端末自身の通信状態の正常／異常を表すための端末状態表示用発光素子４０ｃとを備えて構成されている。勿論、発光素子群の構成は、これに限るものではなく、少なくとも、電源がオンされてあるかオフされてあるかを表示するものであれば、発光素子群の数および形態は問わない。   Similar to the operation input unit 30, the display unit 40 includes a light emitting element group such as an LED in order to indicate that it is operating. The light emitting element group constituting the display unit 40 includes a communication state display light emitting element 40a for indicating that the wireless communication unit 20 is communicating with the ground wireless base station 300, and a rechargeable battery described later. A battery remaining amount display light emitting element 40b for displaying the remaining battery level of 60 in multi-steps with emission color display, and a terminal state display light emitting element 40c for indicating normality / abnormality of the communication state of the terminal itself are provided. It is configured. Of course, the configuration of the light emitting element group is not limited to this, and the number and form of the light emitting element groups are not limited as long as at least whether the power is turned on or off is displayed.

報知音発生部５０は、発報ボタン３０ａへの操作入力があれば、これと連動して周囲への報知音を発生するものであり、所定以上の音量での鳴動が可能なスピーカ又はブザーを備える。この報知音発生部５０は、予め設定しておいた記録音声や人工音声や合成音声を発するものでもよく、携帯型緊急通報無線端末１００が通話可能なタイプのものであれば、もともと備わっているスピーカ又はブザーを報知音発生部５０と兼用させることで内装する部品点数の削減を図ってもよい。   If there is an operation input to the notification button 30a, the notification sound generator 50 generates a notification sound to the surroundings in conjunction with this, and a speaker or buzzer capable of ringing at a predetermined volume or higher is provided. Prepare. This notification sound generation unit 50 may emit a preset recording voice, artificial voice, or synthesized voice, and is originally provided as long as the portable emergency call radio terminal 100 is of a type capable of making a call. It is also possible to reduce the number of parts to be installed by using a speaker or buzzer together with the notification sound generator 50.

充電池６０は、携帯型緊急通報無線端末１００の電源であり、測位電波受信部１０と、無線通信部２０と、操作入力部３０と、表示部４０と、報知音発生部５０と、端末制御部８０とに、電源を供給する。操作入力部３０については、電源不要の単なるボタン群だけで構成されていれば、電源を与える必要はない。充電池６０は、端末制御部８０には、電源を常時供給し続けるものである。   The rechargeable battery 60 is a power source of the portable emergency call radio terminal 100, and includes a positioning radio wave reception unit 10, a radio communication unit 20, an operation input unit 30, a display unit 40, a notification sound generation unit 50, and terminal control. Power is supplied to the unit 80. The operation input unit 30 does not need to be supplied with power as long as it includes only a button group that does not require power. The rechargeable battery 60 continuously supplies power to the terminal control unit 80.

端末制御部８０は、演算機能および情報処理機能を備えるマイクロコンピュータチップを具備し、測位電波受信部１０と、無線通信部２０と、操作入力部３０と、表示部４０と、報知音発生部５０とを状態監視または制御するもので、充電池６０から電源を常時供給し続けられて動作している。そして、基本動作として、充電池６０の電池残量を検知して所定値以下の電池残量になれば電池残量表示用発光素子４０ｃを発光させ、また、測位電波受信部１０での無線電波の受信内容から得られる位置特定のための情報を、無線通信部２０によって地上の無線基地局３００へ無線報知させる。   The terminal control unit 80 includes a microcomputer chip having a calculation function and an information processing function, and includes a positioning radio wave reception unit 10, a wireless communication unit 20, an operation input unit 30, a display unit 40, and a notification sound generation unit 50. Is monitored and controlled, and the power supply is continuously supplied from the rechargeable battery 60 to operate. As a basic operation, when the remaining battery level of the rechargeable battery 60 is detected and the remaining battery level becomes equal to or lower than a predetermined value, the remaining battery level display light emitting element 40c is caused to emit light. The information for specifying the position obtained from the received content is wirelessly notified to the ground wireless base station 300 by the wireless communication unit 20.

次いで、携帯型緊急通報無線端末１００による安全確保の概略を説明する。
携帯型緊急通報無線端末１００は、図５に示すように、測位電波受信部１０がＧＰＳ衛星２００からの電波を捕捉を試み、捕捉したGPS衛星電波の受信内容から得られる位置特定のための情報を、無線通信部２０から地上の無線基地局３００へ、定期的かつ自動的に、無線報知させる。これ以外にも、通知ボタン３０ｃを押下することで、現在位置に係る取得情報を、やはり無線基地局３００へ転送できる。 Next, an outline of ensuring safety by the portable emergency call radio terminal 100 will be described.
As shown in FIG. 5, the portable emergency call wireless terminal 100 tries to capture a radio wave from the GPS satellite 200 by the positioning radio wave receiving unit 10, and information for specifying the position obtained from the received content of the captured GPS satellite radio wave. Is periodically and automatically notified from the wireless communication unit 20 to the ground wireless base station 300. In addition to this, the acquisition information related to the current position can be transferred to the radio base station 300 by pressing the notification button 30c.

上記情報を受けた無線基地局３００は、携帯型緊急通報無線端末１００をサポートするサービスセンター４００に転送し、サービスセンター４００内で異常事態発生が判断されれば、サービスセンター４００から所定の警護サービス会社５００へ緊急通報が届き、警護サービス会社５００は携帯型緊急通報無線端末１００の位置情報を頼りに、現場に緊急出動し、携帯型緊急通報無線端末１００の正規の携行者の保護にあたる。   Receiving the above information, the radio base station 300 transfers the information to the service center 400 that supports the portable emergency call radio terminal 100, and if an abnormal situation occurs in the service center 400, the service center 400 sends a predetermined security service. The emergency call reaches the company 500, and the security service company 500 is dispatched to the site based on the location information of the portable emergency call radio terminal 100, and protects the authorized carryer of the portable emergency call radio terminal 100.

なお、携帯型緊急通報無線端末１００の現在位置を把握する手法は、携帯型緊急通報無線端末１００と無線基地局３００と一乃至複数のサービスセンター４００と警護サービス会社５００との一乃至複数の拠点に設置された演算サーバの単独演算もしくは連携演算による所謂ネットワークアシスト方式に限らず、測位電波受信部１０と無線通信部２０と端末制御部８０とのいずれかを用いて携帯型緊急通報無線端末１００の内部で演算を完結してしまう単独測位方式であってもよく、これらのように従来知られたものでかまわない。   The method of grasping the current location of the portable emergency call radio terminal 100 is one or more bases of the portable emergency call radio terminal 100, the radio base station 300, one or more service centers 400, and the security service company 500. The mobile emergency call wireless terminal 100 is not limited to a so-called network assist method based on a single calculation or a cooperative calculation of a calculation server installed in the mobile phone, and uses any one of the positioning radio wave reception unit 10, the radio communication unit 20, and the terminal control unit 80. It may be a single positioning method that completes the calculation inside the device, and may be a conventionally known method such as these.

このような、携帯型緊急通報無線端末１００は、電源オフ操作がされたときには、以下のように動作する。これについて、図６のフローチャートとともに説明する。ここでの動作主体は、端末制御部８０である。   Such a portable emergency call radio terminal 100 operates as follows when the power-off operation is performed. This will be described with reference to the flowchart of FIG. The operation subject here is the terminal control unit 80.

この手順によれば、端末制御部８０は、通常使用モード中（ステップＳ１０）に、操作入力部３０への操作入力を検知すると（ステップＳ２０）、電源オフ操作入力（電源入切ボタン３０−２の押圧）であるか否かを判断し、電源オフ操作入力でなければ、その操作入力に対処する諸動作を行い依然として通常使用モード中（ステップＳ１０）を維持する（ステップＳ３０）が、電源オフ操作入力であれば、電源オフ許可判断モードに移行し、所定の時間を計るべくタイマーカウントをスタートさせる（ステップＳ４０）。   According to this procedure, when the terminal control unit 80 detects an operation input to the operation input unit 30 (step S20) during the normal use mode (step S10), the power-off operation input (power on / off button 30-2). If it is not a power-off operation input, various operations corresponding to the operation input are performed and the normal use mode (step S10) is still maintained (step S30). If it is an operation input, the power-off permission determination mode is entered, and a timer count is started to measure a predetermined time (step S40).

端末制御部８０は、引き続き、電源入切ボタン３０ｂを含めて操作入力部３０のいずれかへの操作入力を検知したら、その操作入力が所定の操作入力である場合と、操作入力があったが所定の操作入力ではなかった場合と、操作入力を何れも検知できなかった場合との、計３通りの場合のいずれであるかを判断する（ステップＳ５０）。このステップＳ５０にて、操作入力が所定の操作入力である場合には、正規の電源オフ操作入力が行われたのであるから、この場合にのみ、表示部４０への電源供給を停止し、かつ、無線通信部２０への電源供給量を、地上基地局３００との通信が不可能となる程度に低減させる（ステップＳ６０）。   When the terminal control unit 80 continues to detect an operation input to any of the operation input units 30 including the power on / off button 30b, the operation input is a predetermined operation input and there is an operation input. It is determined whether there are a total of three cases, that is, a case where the operation input is not a predetermined operation and a case where none of the operation inputs can be detected (step S50). In step S50, when the operation input is a predetermined operation input, since the regular power-off operation input has been performed, the power supply to the display unit 40 is stopped only in this case, and Then, the power supply amount to the wireless communication unit 20 is reduced to such an extent that communication with the ground base station 300 is impossible (step S60).

この電力供給量の低減は、携帯型緊急通報無線端末１００は、防犯上なんら問題無い正常時であっても、その目的から、地上基地局３００との定期通信を行い地上基地局３００の地理上の監視範囲内に存在することが要求されているため、無線通信部２０については、最低限の電源によって、所謂スリープモードで状態維持される必要がある。   This reduction in the amount of power supply is achieved by the fact that the portable emergency call radio terminal 100 performs regular communication with the ground base station 300 for the purpose of the crime even if it is normal when there is no problem in crime prevention. Therefore, the wireless communication unit 20 needs to be maintained in a so-called sleep mode with a minimum power source.

このような端末の電源オフ状態では、携帯型緊急通報無線端末１００を構成する部品のうち、報知音発生部５０と振動検知部６０とは使わないので、充電池７０の供給電源は、測位電波受信部１０と無線通信部２０と表示部４０と端末制御部８０とで殆どが消費され、しかもその大部分の電力消費主体は測位電波受信部１０と無線通信部２０と表示部４０という３つの部品である。このうち測位電波受信部１０は、端末の電源オフ状態では電力を消費することはなく、無線通信部２０は上述の通りスリープモードで運用することになり、表示部４０については電源供給を完全に断つので電力を消費することは無い。このような電源オフ状態にするためには、端末制御部８０が、充電池７０から各部品への供給電力路上に設けた開閉スイッチ（不図示）を電気制御で開制御することにより、充電池７０から各部品への電力供給を停止すればよい。このとき、携帯型緊急通報無線端末１００の消費電力は、極低減状態になっている。   In such a power-off state of the terminal, the notification sound generator 50 and the vibration detector 60 are not used among the components constituting the portable emergency call radio terminal 100. The receiving unit 10, the wireless communication unit 20, the display unit 40, and the terminal control unit 80 are mostly consumed, and most of the power consuming entities are the positioning radio wave receiving unit 10, the wireless communication unit 20, and the display unit 40. It is a part. Among them, the positioning radio wave receiving unit 10 does not consume power when the terminal is turned off, the wireless communication unit 20 operates in the sleep mode as described above, and the display unit 40 is completely supplied with power. The power is not consumed because it is cut off. In order to enter such a power-off state, the terminal control unit 80 opens and closes the open / close switch (not shown) provided on the power supply path from the rechargeable battery 70 to each component by electric control, thereby rechargeable battery. What is necessary is just to stop the electric power supply from 70 to each component. At this time, the power consumption of the portable emergency call radio terminal 100 is extremely reduced.

なお、操作入力部３０が、本実施形態の如く単なる操作ボタン群ではなく、小型タッチパネル液晶のように電力供給を要する部品であれば、この操作入力部３０への電源供給もストップする必要があるが、電源オン操作入力を検知するための操作入力部品だけには電力供給しておく必要がある。   If the operation input unit 30 is not a simple operation button group as in the present embodiment, but is a component that requires power supply such as a small touch panel liquid crystal, it is also necessary to stop power supply to the operation input unit 30. However, it is necessary to supply power only to the operation input component for detecting the power-on operation input.

このステップＳ６０の後、操作入力部３０への電源オン操作入力を検知すると（ステップＳ７０）、電源オフ状態から電源オン状態となり、端末制御部８０は充電池７０から各部品への供給電力路上に設けた開閉スイッチ（不図示）を電気制御で閉制御することにより、充電池７０から各部品への電力供給を再開する。このとき、測位電波受信部１０と無線通信部２０と端末制御部８０とのいずれかに記憶されていた測位に関する情報を更新すべく、起動時に測位情報（アルマナックやエフェメリス）の有効期限を確認し、必要に応じてデータの初期化を行う（ステップＳ８０）。このステップＳ８０に相当する工程は、所謂ホットスタートやコールドスタートなどＧＰＳに付随する仕様に応じて、行えばよい。このステップＳ８０を終えると、通常使用モード中になるので、ステップＳ１０に動作を戻す。   After this step S60, when a power-on operation input to the operation input unit 30 is detected (step S70), the power-off state is changed to the power-on state, and the terminal control unit 80 is on the power supply path from the rechargeable battery 70 to each component. The power supply from the rechargeable battery 70 to each component is resumed by closing the provided opening / closing switch (not shown) by electrical control. At this time, the expiration date of the positioning information (almanac or ephemeris) is confirmed at the time of activation in order to update the information regarding the positioning stored in any of the positioning radio wave reception unit 10, the wireless communication unit 20, and the terminal control unit 80. The data is initialized as necessary (step S80). The process corresponding to step S80 may be performed according to specifications accompanying the GPS, such as so-called hot start and cold start. When step S80 is completed, the normal use mode is entered, and the operation returns to step S10.

一方、ステップＳ５０にて、検知した操作入力が、所定の操作入力ではなかった場合には、端末制御部８０は、振動検知部６０を起動させて振動検知を行わせ（ステップＳ９０）、所定量以上の振動量が検知されるか否かを識別する（ステップＳ１００）。このステップＳ１００にて、所定量以上の振動量が検知されると（Ｙｅｓルート）、所定の操作入力ができずに、携帯型緊急通報無線端末１００を振り回している状況から、誘拐など正規の携行者に何らかのアクシデントが起こったものと推定し、無線通信部２０を通じて地上の無線基地局３００へ異常発生の無線報知を行う（ステップＳ１１０）。   On the other hand, if the detected operation input is not a predetermined operation input in step S50, the terminal control unit 80 activates the vibration detection unit 60 to perform vibration detection (step S90), and the predetermined amount. It is identified whether or not the above vibration amount is detected (step S100). If a vibration amount greater than or equal to a predetermined amount is detected in this step S100 (Yes route), regular carrying such as kidnapping from the situation where the portable emergency call radio terminal 100 is being swung without performing a predetermined operation input. It is presumed that some accident has occurred to the person, and radio notification of the occurrence of abnormality is performed to the radio base station 300 on the ground through the radio communication unit 20 (step S110).

ステップＳ１００で所定量以上の振動量が検知されなかった場合（Ｎｏルート）と、ステップＳ１１０での通報の後、端末制御部８０は、ステップＳ４０でカウントスタートしていたタイマーカウントが所定の時間を経過しているか否かを調べる（ステップＳ１２０）。未だ経過していなければ、ステップＳ５０に動作を戻し、経過していれば、ステップＳ４０以降に何らかの操作入力があったか否かを振り返る（ステップＳ１３０）。   When the vibration amount equal to or greater than the predetermined amount is not detected in step S100 (No route), after the notification in step S110, the terminal control unit 80 determines that the timer count that has been started in step S40 is equal to the predetermined time. It is checked whether or not it has elapsed (step S120). If it has not yet elapsed, the operation is returned to step S50, and if it has elapsed, whether or not there is any operation input after step S40 is looked back (step S130).

また、ステップＳ５０での判断過程において、操作入力が全く検知できなかった場合には、ステップＳ１２０に動作が移行する。つまり、ステップＳ５０とステップＳ１２０とを回帰し続けてステップＳ１３０に至った場合には、ステップＳ４０でタイマーカウントがカウントスタートしてから、何らの操作入力もなされないまま、タイマーがカウントアップしたことになる。この場合には、一回も操作入力が無いので、電源オフとすべく不正な操作入力が発生したわけではないから、報知音発生部５０を鳴動させることはなく、電源オフ許可判断モードから動作を抜けて通常使用モード（ステップＳ１０）に諸動作を戻す（ステップＳ１３０後のＹｅｓルート）。これに対して、ステップＳ１３０にて、ステップＳ４０以降に何らかの操作入力があれば、報知音発生部５０を鳴動させ周囲に向けた発報を行うのである（ステップＳ１３０後のＮｏルート〜ステップＳ１４０）。なお、ステップＳ１４０での発報開始の後は、電源オフ許可判断モードを抜けて、通常使用モード（ステップＳ１０）に戻るのであるが、報知音発生部５０の鳴動は周囲の注目を誘うための動作であるので、通常使用モードに戻った後も、時限制御ではなく鳴動を継続させることが望ましい。なお、この場合のステップＳ１０では、報知音発生部５０の鳴動を停止させる操作入力を受け付け、規定の操作入力であれば報知音発生部５０の鳴動を停止させることが、電源を余計に消費させないという観点から、より望ましい。   If no operation input is detected in the determination process in step S50, the operation proceeds to step S120. In other words, when step S50 and step S120 are continuously regressed and step S130 is reached, the timer counts up without any operation input after the timer count starts in step S40. Become. In this case, since there has been no operation input even once, no unauthorized operation input has been generated to turn off the power. Therefore, the notification sound generator 50 is not sounded and the operation is performed from the power-off permission determination mode. The operation is returned to the normal use mode (step S10) (Yes route after step S130). On the other hand, if there is any operation input after step S40 in step S130, the notification sound generating unit 50 is sounded to issue a notification toward the surroundings (No route after step S130 to step S140). . In addition, after starting the alarm in step S140, the power-off permission determination mode is exited and the normal use mode (step S10) is resumed, but the ringing of the notification sound generator 50 is for attracting the attention of the surroundings. Since this is an operation, it is desirable to continue ringing rather than timed control even after returning to the normal use mode. In step S10 in this case, an operation input for stopping the ringing of the notification sound generating unit 50 is received, and if the specified operation input is received, stopping the ringing of the notification sound generating unit 50 does not consume extra power. It is more desirable from the viewpoint of.

実施例２は、図１を参照して説明する。   The second embodiment will be described with reference to FIG.

実施例２とされる携帯型緊急通報無線端末１００の、実施例１とは異なる特徴点は、第２の電池収納室Ｖ２に収納される別の充電池７０を、第１の電池収納室Ｖ１に収納される充電池６０と同様の電力供給を行うスペア充電池としている点であり、この別の充電池７０の一対の接続端子７０ａは、実施例１におけるプリント配線板９０上のダミー端子９０ａに替えて設けられたスペア充電池接続端子９０ｃに接続され、第１の電池収納室Ｖ１に収納される充電池６０と同様に、測位電波受信部１０、無線通信部２０、端末制御部８０、表示部４０に電源供給が可能なように、プリント配線板９０に形成された電源供給路（不図示）に接続されている点にある。   The feature of the portable emergency call radio terminal 100 of the second embodiment different from that of the first embodiment is that another rechargeable battery 70 housed in the second battery housing room V2 is replaced with the first battery housing room V1. This is a spare rechargeable battery that supplies power similar to that of the rechargeable battery 60 housed in the battery. A pair of connection terminals 70a of the other rechargeable battery 70 is a dummy terminal 90a on the printed wiring board 90 in the first embodiment. In the same manner as the rechargeable battery 60 that is connected to the spare rechargeable battery connection terminal 90c provided instead of the rechargeable battery 60 and is accommodated in the first battery accommodating chamber V1, the positioning radio wave receiving unit 10, the wireless communication unit 20, the terminal control unit 80, The display unit 40 is connected to a power supply path (not shown) formed on the printed wiring board 90 so that power can be supplied to the display unit 40.

これにより、別の充電池７０は、第１の電池収納室Ｖ１に収納される正規の充電池６０と同様に電力供給を行うスペア充電池として機能する。従って、この別の充電池７０が引き抜かれるまでは、電源供給源が２つ存在することになり、バックアップ電源をひとつ備えたことと等しい。   Thereby, the other rechargeable battery 70 functions as a spare rechargeable battery that supplies power in the same manner as the regular rechargeable battery 60 stored in the first battery storage chamber V1. Accordingly, there are two power supply sources until the other rechargeable battery 70 is pulled out, which is equivalent to having one backup power source.

また、別の充電池７０を、電力供給するスペア電池としたことに対応して、端末制御部８０における別の充電池７０脱離検知機能も変更している。すなわち、端末制御部８０は、スペア充電池接続端子９０ｃに印加されている電圧値を読み取り、この読み取った電圧値として所定の電圧値が得られれば、一対の接続端子７０ａがスペア充電池接続端子９０ｃと接続している状態であると判断して、特段の動作は行わないが、所定の電圧値が得られない場合は、一対の接続端子７０ａがスペア充電池接続端子９０ｃから離脱している状態であると判断して、無線通信部２０を介して地上の無線基地局３００へ異常発生の旨の無線発報を行う。これにより、別の充電池７０が引き抜かれてしまった事実を、地上の無線基地局３００へ自動通報できる。なお、端末制御部８０がスペア充電池接続端子９０ｃに印加されている電圧値を読み取るのは、定期的であってもよいし、何か操作入力がなされた都度であってもよい。   Further, in response to the use of another rechargeable battery 70 as a spare battery for supplying power, the other rechargeable battery 70 detachment detection function in the terminal control unit 80 is also changed. That is, the terminal control unit 80 reads the voltage value applied to the spare rechargeable battery connection terminal 90c, and if a predetermined voltage value is obtained as the read voltage value, the pair of connection terminals 70a become the spare rechargeable battery connection terminals. It is determined that it is connected to 90c, and no special operation is performed. However, when a predetermined voltage value cannot be obtained, the pair of connection terminals 70a is detached from the spare rechargeable battery connection terminal 90c. It is determined that the current state is present, and wireless notification is issued to the terrestrial wireless base station 300 via the wireless communication unit 20 to indicate that an abnormality has occurred. Thereby, the fact that another rechargeable battery 70 has been pulled out can be automatically notified to the ground radio base station 300. Note that the terminal controller 80 may read the voltage value applied to the spare rechargeable battery connection terminal 90c periodically or whenever an operation input is made.

ここで、地上の無線基地局３００にとどまらず所定のサービスセンター４００に通報転送先を予め設定しておけば、地上の無線基地局３００経由で地上の有線無線の通信網を経由して、所定の通報先たる所定のサービスセンター４００に異常発生の事象を早期に知らしめることも可能になる。   In this case, if a notification transfer destination is set in advance in a predetermined service center 400 in addition to the ground wireless base station 300, the predetermined route is transmitted via the ground wireless base station 300 via the ground wired wireless communication network. It is also possible to notify the predetermined service center 400, which is the report destination, of an abnormal event at an early stage.
