Description

  The present invention relates to a wireless communication apparatus having a crime prevention function.

  In recent years, there have been many incidents where children and women are exposed to danger, and crime prevention devices are in the spotlight to avoid such incidents. However, a dedicated crime prevention device that occupies a certain volume lacks versatility and may not be useful in an emergency. Therefore, the mounting of a crime prevention function in a wireless communication device represented by a mobile phone or a PHS (Personal Handy phone System) that is considered to be owned by most individuals is now attracting attention.

  As a security function mounted on the wireless communication device, for example, a buzzer sound (warning sound) can be obtained by removing a strap dedicated to the security function provided in the wireless communication device or performing a predetermined key operation. The most widely known wireless communication apparatus is configured to generate the above-described problem and functions as a security buzzer. According to this, since a function as a security buzzer is installed in a radio communication device that is often carried by a user at all times, it is not necessary to carry a security buzzer separately, and the security function can be used immediately in an emergency. it can.

  In addition, as a wireless communication device equipped with another crime prevention function, a communication device is disclosed that automatically receives position information when a call operation or a call operation ends and transmits the received position information to a predetermined destination ( For example, Patent Document 1). According to this, when a user such as a child is attacked by a suspicious person, a call operation or a call operation to a predetermined destination (communication terminal) such as a parent is performed from the possessed communication terminal, and the user is positioned at the predetermined destination. It is said that it is possible to notify information reliably.

  Further, as a wireless communication device equipped with another crime prevention function, when a predetermined key is operated, a power-off state and a power-on state that acquires position information and transmits the acquired position information to a predetermined destination There has been disclosed a communication device that is repeatedly configured to be in a pseudo power-off state (for example, Patent Document 2). When such a communication device receives information with a predetermined flag when it is in the power-on state in the pseudo power-off state, it shifts from the pseudo power-off state to the normal power-on state. According to this, since a communication terminal that is in a pseudo power-off state is turned on by receiving information with a predetermined flag from another communication terminal, the mobile terminal is remotely operated from the other communication terminal. It is possible to do.

  However, in the wireless communication device functioning as the above-described crime prevention buzzer, it is easy for a suspicious person who has noticed that the buzzer sounded to try to remove the battery pack of the wireless communication device in order to stop the buzzer sound. is expected. In the communication devices described in Patent Literature 1 and Patent Literature 2 described above, a suspicious person may try to remove the battery pack in order to stop the function of the communication device. Therefore, in the case of the above-described wireless communication device (communication device), the power supply of the wireless communication device is cut off if the battery pack is removed by a suspicious person even though it has a crime prevention function. For this reason, there has been a problem that the crime prevention function cannot be fully exhibited when an emergency occurs.

Therefore, in order to solve such a problem, a secondary battery, a battery storage part for storing the secondary battery, a cover that covers the battery storage part, and an alarm generation means for generating an alarm sound or the like by a predetermined operation , And a configuration in which such a secondary battery cannot be easily removed is disclosed (for example, Patent Documents 3, 4 and 5). With the mobile phones described in Patent Documents 3, 4, and 5, it is difficult for a suspicious person to remove the battery pack from the mobile phone (wireless communication device). Therefore, it is possible to reduce the occurrence of a situation where the power source of the wireless communication device is cut off.

  However, when the battery pack cannot be removed from the wireless communication device as in the mobile phones (wireless communication devices) described in Patent Documents 3, 4 and 5, the suspicious person destroys the wireless communication device. There is a possibility of trying to cut off the power supply, and there is a risk of leaving the wireless communication device where the security buzzer continues to ring in the field. When these situations occur, the effect of the crime prevention function mounted on the wireless communication device is drastically reduced as in the case where the battery pack is removed.

(Wireless communication system 100)
FIG. 1 is an explanatory diagram showing a schematic connection relationship of the wireless communication system 100. The wireless communication system 100 includes a wireless communication device 110, a base station 120 that establishes wireless communication with the wireless communication device 110, and an Ethernet (registered trademark), ISDN (Integrated Services Digital Network) line connected to the base station 120. , A communication network 130 constituted by the Internet, a dedicated line, etc., a relay server 140 that relays each base station 120 through the communication network 130, and a contact terminal 150. Here, in the present embodiment, a mobile phone owned by a contact user is illustrated as a communication device serving as the contact terminal 150. However, the present invention is not limited to this, and the electronic device, landline phone, personal computer, and the like described above are not limited thereto. It is also possible to use.

  In the wireless communication system 100, the wireless communication device 110 executes a call or communication with another wireless communication device through wireless communication with the base station 120, and is connected to each service provider via the communication network 130. Various services can be received from a web server (not shown). In particular, in the present embodiment, communication with the contact terminal 150 registered in the wireless communication device is established via the wireless communication system 100, and its critical state is transmitted to the contact terminal 150. It becomes possible. The contact user who has the contact terminal 150 can take an early safety measure that protects the user who has the wireless communication device 110 in response to the transmission matter. Hereinafter, a specific configuration of the wireless communication device 110 will be described in detail.

(Wireless communication device 110)
FIG. 2 is a functional block diagram illustrating a hardware configuration of the wireless communication apparatus 110, and FIG. 3 is a perspective view illustrating an appearance of the wireless communication apparatus 110. 3A is a front perspective view, and FIG. 3B is a rear perspective view. In the present embodiment, a straight-type mobile phone is illustrated as the wireless communication apparatus 110, but the present invention is not limited to this, and a folding-type or slide-type mobile phone may be used.

  The wireless communication device 110 includes a control unit 202, a display unit 204, an audio input unit 206, an audio output unit 208, a light emitting unit 210, a vibration output unit 212, an imaging unit 214, an operation unit 216, 1 battery 220, battery mounting part 230, second battery 240 or dummy battery 250, battery cover 260, resistance measurement part 270, battery cover detection part 272, capacitor 274, first switch 276, 2 switch 278, attachment / detachment determination unit 280, detection unit 282, memory 284, wireless communication unit 288, and GPS reception unit 290.

  The control unit 202 manages and controls the functions of the entire wireless communication device 110 using a semiconductor integrated circuit including a central processing unit (CPU), and uses a program in the memory 284 to make a call function, mail transmission / reception function, imaging function, and music playback. It also performs functions and TV viewing functions.

  The display unit 204 includes a liquid crystal display (LCD), an EL (Electro Luminescence), a PDP (Plasma Display Panel), and the like. The display unit 204 can display information for a user such as Web content, GUI (Graphical User Interface) of an application stored in the memory 284 or provided from the relay server 140 via the communication network 130. .

  When the attachment / detachment determination unit 280 described later determines that the second battery 240 or the dummy battery 250 has been detached from the wireless communication device 110, that is, when the wireless communication device 110 is set to the power supply pseudo disconnection mode. The output is limited (no output is performed). Thereby, since the display on the display unit 204 is stopped, it is possible to distract the attention to the wireless communication device 110 by making it appear to the suspicious person that the power of the wireless communication device 110 has been cut off.

  The voice input unit 206 includes voice recognition means such as a microphone, and converts a user voice input during a call into an electrical signal that can be processed in the wireless communication device 110.

  When the attachment / detachment determination unit 280 described later determines that the second battery 240 or the dummy battery 250 is detached from its own device (the wireless communication device 110), the voice input unit 206 (the wireless communication device 110 enters the power supply pseudo disconnection mode). Once set), it ’s a good idea to input audio. Thereby, based on the input voice, it is possible to determine the situation where the user is placed and to identify a suspicious person.

  The audio output unit 208 is constituted by a speaker, and converts the voice signal of the other party received by the wireless communication device 110 into voice and outputs it. In addition, a ring tone, an operation sound of the operation unit 216, an alarm sound, and the like can be output.

  When the detection unit 282 described later detects a critical situation of the user based on the user's input and the operation mode of the wireless communication device 110 is set to a security mode that activates the security function, the audio output unit 208 It is good to output a warning sound. Thereby, the critical situation of the user can be notified to surrounding people and the suspicious person can be threatened.

  When the attachment / detachment determination unit 280, which will be described later, determines that the second battery 240 or the dummy battery 250 is detached from its own device (when the wireless communication device 110 is set to the power supply pseudo disconnection mode), the audio output unit 208 outputs Do not do. As a result, the voice output from the voice output unit 208 is stopped, so that the suspicious person can appear to have been turned off and the suspicious person's attention can be distracted.

  The light emitting unit 210 includes an LED (Light Emitting Diode), an EL light emitter, a sub LCD, and other electronic components that can be illuminated. As a result, for example, when voice output is not possible, it is possible to recognize an incoming call or mail reception by the light emission of the light emitting unit.

  The light emitting unit 210 is disabled when the attachment / detachment determination unit 280 described later determines that the second battery 240 or the dummy battery 250 is detached from the device (when the wireless communication device 110 is set to the power supply pseudo disconnection mode). It is good to be As a result, the light emission of the light emitting unit 210 is stopped, and it is possible to make the suspicious person appear as if the power of the wireless communication device 110 has been cut off, and the suspicious person can be deceived.

  The vibration output unit 212 includes an electric motor (not shown) and a rigid body (not shown) such as a metal provided on a rotating shaft (not shown) of the electric motor and having an eccentric center of gravity, and rotates the rigid body. Thus, vibration vibration can be applied to the wireless communication device 110. That is, the vibration output unit 212 is a vibrator. This makes it possible to recognize incoming calls, e-mails, and alarms where voice output is not possible, such as trains and conferences.

  When the attachment / detachment determination unit 280 described later determines that the second battery 240 or the dummy battery 250 is detached from its own device (when the wireless communication device 110 is set to the power supply pseudo disconnection mode), the vibration output unit 212 operates. It should be invalidated. Thereby, since the vibration output by the vibration output unit 212 is stopped, it is possible to make it appear to the suspicious person that the power of the wireless communication device 110 has been cut off.

  The imaging unit 214 is configured by a video element such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS), and can thereby capture an image (a still image or a moving image).

  When the attachment / detachment determination unit 280 described later determines that the second battery 240 or the dummy battery 250 is detached from the image capturing unit 214 (when the wireless communication device 110 is set to the power supply pseudo disconnection mode), the imaging unit 214 captures an image. It is good to do. As a result, the captured image can be used to identify the suspicious person.

  More preferably, when the battery lid detection unit 272 described later detects that the battery lid 260 has been removed from the wireless communication device 110, the imaging unit 214 causes the attachment / detachment determination unit 280 to detect the second battery 240 or dummy from its own device. Even when it is not determined that the battery 250 is detached, it is preferable to take an image. As a result, when the suspicious person removes the battery cover 260 in order to remove the second battery 240 or the dummy battery 250, the imaging unit 214 starts taking an image. Therefore, it is possible to take a picture of the face of a suspicious person who removes the battery cover 260 and then tries to remove the second battery 240 or the dummy battery 250. Therefore, it is possible to photograph the suspicious person's face more reliably.

  The operation unit 216 includes a plurality of movable operation keys (hardware keys) such as a keyboard, a cross key, and a joystick, and accepts a user operation input. In the present embodiment, a detection unit 282 described later is provided to detect a critical situation of the user. However, for example, the operation unit 216 may be the detection unit 282 and a predetermined key operation by the user may be a user input.

  The first battery 220 is invisible inside the wireless communication device 110 and supplies power for operating the wireless communication device 110. As a result, even if a suspicious person removes the second battery 240 from the wireless communication device 110, power can be supplied from the first battery 220. Therefore, since the power is not cut off even after the second battery 240 is removed, the wireless communication device 110 can continue to operate. Moreover, since it is incorporated invisible, it can be avoided that a suspicious person notices the presence of the first battery 220.

  The battery mounting unit 230 is mounted with either a second battery 240 or a dummy battery 250 described later. Thereby, any one of them can be attached to the wireless communication apparatus 110. In this way, not only the first battery 220 but also either the second battery 240 or the dummy battery 250 can be attached, so that the second battery 240 or the dummy battery 250 attached to the battery attachment part 230 is removed. A suspicious person can be made to assume that the power supply source of the wireless communication apparatus 110 has been excluded. As a result, attention to the built-in first battery 220 can be diverted.

  In addition, since the wireless communication device 110 can attach and detach the second battery 240 and the dummy battery 250, the user can select one of these as a battery pack to be mounted on the wireless communication device 110 of the user. It becomes possible. Therefore, a user who consumes a large amount of power and desires to supply a large amount of power, such as frequently using the wireless communication device 110, may select the second battery 240 as a member to be mounted on the battery mounting unit 230. Thereby, since electric power can be obtained not only from the first battery 220 but also from the second battery 240, it is possible to increase the amount of power supplied to the wireless communication device 110 and extend the usage time. Moreover, since the second battery 240 can be carried together with the wireless communication device 110 by attaching the second battery 240 to the battery attachment unit 230, it is possible to prevent forgetting to carry a spare battery pack. .

  Further, the second battery 240 can be easily attached to and detached from the battery mounting portion 230, and no special tool or the like is required for the attachment / detachment work. Therefore, the user's replacement work is not hindered, and convenience is not lowered.

  Moreover, since the 2nd battery 240 can be easily attached or detached to the battery mounting part 230 without requiring a special tool, a suspicious person can remove the 2nd battery 240 easily. Then, after the second battery 240 is removed, the wireless communication device 110 is set to the power pseudo-disconnection mode, is supplied with power from the built-in first battery 220, and outputs from the display unit 204 and the audio output unit 208. Stops. As a result, the wireless communication device 110 appears to be in a “power off” state (a state in which the power is cut off). Accordingly, since the suspicious person can assume that the power of the wireless communication apparatus 110 has been cut off, the suspicious person's action is merely to remove the second battery 240, and the wireless communication apparatus 110 is not destroyed. .

  Note that a user who does not need so much power supply may select the dummy battery 250 as a member to be attached to the battery attachment unit 230. Thereby, the cost required for the battery pack of the wireless communication apparatus 110 can be reduced.

  The second battery 240 is a secondary battery that can be attached to and detached from the wireless communication device 110, that is, the battery mounting unit 230, and supplies power for operating the wireless communication device 110. The second battery 240 has a power supply terminal for supplying power to the wireless communication device 110. Since the second battery 240 can be easily attached to and detached from the battery mounting portion 230, the replacement work by the user is not hindered, and convenience is not lowered. In addition, as the 2nd battery 240, a lithium ion battery, a nickel metal hydride battery, etc. can be used suitably.

  The second battery 240 has an ID resistor 240a. Thereby, the attachment / detachment determination unit 280 described later can identify that the member mounted on the battery mounting unit 230 is the second battery 240.

  The dummy battery 250 is a model member that can be attached to and detached from the wireless communication device 110 (battery mounting unit 230) and that does not supply power for operating the wireless communication device 110. The dummy battery 250 has a pseudo power supply terminal having substantially the same shape as the power supply terminal of the second battery 240. Thereby, the appearance of the dummy battery 250 can be made to resemble the second battery 240.

  The dummy battery 250 may have substantially the same shape as the second battery 240. As a result, the dummy battery 250 and the second battery 240 have very similar appearances, and it is difficult to distinguish them from the appearance. Thereby, the suspicious person who removed the dummy battery 250 can be made to think that the dummy battery 250 is a regular battery pack (secondary battery), and the first battery 220 built in the wireless communication device 110 is connected to the suspicious person. Attention can be diverted.

  The dummy battery 250 may have substantially the same weight as the second battery 240. Thereby, the feeling when holding the dummy battery 250 in hand, that is, the weight feeling of the dummy battery 250 is the same as the weight feeling of the second battery 240. Therefore, when the suspicious person removes the dummy battery 250 attached to the wireless communication device 110, the dummy battery 250 can be more strongly assumed to be a regular battery pack (secondary battery). This makes it possible to distract the attention of the first battery 220.

  The dummy battery 250 has an ID resistor 250a. Thereby, the attachment / detachment determination unit 280 described later can identify that the member mounted on the battery mounting unit 230 is the dummy battery 250.

  The ID resistor 240a and the ID resistor 250a are configured to have different resistance values. Accordingly, the attachment / detachment determination unit 280 can reliably identify these values based on the resistance values measured by the resistance measurement unit 270.

  The battery lid 260 is a lid for covering the second battery 240 and the dummy battery 250 attached to the wireless communication device 110. The battery lid 260 can be removed from the wireless communication device 110 by sliding in the direction of the white arrow. The battery lid 260 may adopt any opening method, and may be slid in either the vertical, horizontal, left, or right direction as long as it is a slide type, or may be an open / close type using any edge as a hinge. Alternatively, the battery lid 260 may be opened while maintaining a horizontal state.

  In the present embodiment, the battery lid 260 is provided on the surface on which the imaging unit 214 is disposed (see FIG. 3B). This makes it possible to reliably photograph the face of a suspicious person who is trying to remove the battery lid 260, the second battery 240, or the dummy battery 250.

  The resistance measurement unit 270 measures a resistance value (resistance value) provided in the wireless communication device 110. As a result, the attachment / detachment determination unit 280, which will be described later, uses this value to determine whether or not either the second battery 240 or the dummy battery 250 is attached to the own device (battery attachment unit 230) and attach to the own device. Whether the battery pack (member) being used is the second battery 240 or the dummy battery 250, that is, whether the second battery 240 or the dummy battery 250 is attached to or detached from the wireless communication device 110 easily and reliably. It becomes possible to do.

  The battery lid detection unit 272 detects that the battery lid 260 has been removed from the wireless communication device 110. Accordingly, as described above, the imaging unit 214 can start capturing an image when the battery lid 260 is removed.

  The capacitor 274 is built in the wireless communication device 110 and temporarily stores electricity. Accordingly, when the first switch 276 and the second switch 278 described later are switched, the power stored in the capacitor 274 can be supplied to the wireless communication device 110. Therefore, it is possible to avoid an instantaneous power interruption at the time of switch switching.

  The first switch 276 activates a circuit for supplying power to the wireless communication device 110 from the first battery 220. The first switch 276 is turned on when power is supplied from the first battery 220, and is turned off when power is supplied from the second battery 240.

  The second switch 278 and a circuit for supplying power to the wireless communication device 110 from the second battery 240 are activated. The second switch 278 is turned off when power is supplied from the first battery 220, and is turned on when power is supplied from the second battery 240.

  As described above, by switching the first switch 276 and the second switch 278, it is possible to supply power to the wireless communication apparatus 110 from either the first battery 220 or the second battery 240. Accordingly, when the suspicious person removes the second battery 240 from the wireless communication device 110, the attachment / detachment determination unit 280 determines that the second battery 240 is not attached to the wireless communication device 110, and the first battery 220 receives power. Supplied. Therefore, even after the second battery 240 is removed, the power is not cut off, the wireless communication device 110 can continue to operate, and the crime prevention function can be fully exhibited.

  The attachment / detachment determination unit 280 determines whether the second battery 240 or the dummy battery 250 is attached to or detached from the wireless communication device 110 using the resistance value measured by the resistance measurement unit 270. In the present embodiment, the attachment / detachment determination unit 280 determines whether the second battery 240 or the dummy battery 250 is attached or detached using the resistance value measured by the resistance measurement unit 270. However, the present invention is not limited to this. Not what you want. For this determination, other elements that change due to the attachment or detachment of the second battery 240 or the dummy battery 250 may be used. For example, a current or voltage in the circuit can be used instead of the resistor.

  When the attachment / detachment determination unit 280 determines that the second battery 240 or the dummy battery 250 has been detached from the wireless communication device 110, the control unit 202 sets at least the display unit 204 and the audio output unit as to the operation mode of the wireless communication device 110. 208 is set to the power-off pseudo-disconnection mode in which the output 208 is not performed (stopped). Thereby, since the display on the display unit 204 and the audio output from the audio output unit 208 are stopped, it is possible to make the suspicious person appear as if the power of the wireless communication device 110 is cut off, and the wireless communication of the suspicious person is performed. Attention to the device 110 can be diverted.

  Note that, in the above simulated power-off mode, in addition to the display unit 204 and the audio output unit 208, the operation of one or both of the light emitting unit 210 and the vibration output unit 212 may be invalidated. As a result, the vibration output from the vibration output unit 212 and the light emission of the light emitting unit 210 are stopped, and thus the operations that the suspicious person can visually recognize and feel are invalidated among the operations of the wireless communication device 110. Therefore, it is possible to make the suspicious person appear as if the power of the wireless communication device 110 has been cut off, and the suspicious person's attention to the wireless communication device 110 can be further diverted.

  If the attachment / detachment determination unit 280 determines that the second battery 240 is attached to the wireless communication device 110, power for operating the wireless communication device 110 is preferentially supplied from the second battery 240. The first battery 220 may be supplied after the power stored in the second battery 240 is consumed. Thereby, electric power is preferentially supplied from the second battery 240, and the electric power stored in the first battery 220 can be kept in the meantime. Therefore, when the second battery 240 is removed from the first battery 220 by the suspicious person, a large amount of electric power is supplied to the wireless communication device 110 and the wireless communication is performed after the second battery 240 is removed by the suspicious person. It is possible to lengthen the time during which the device 110 continues to operate.

  Further, when the attachment / detachment determination unit 280 determines that the second battery 240 is attached to the wireless communication device 110, the first battery 220 is preferentially charged, and after the charging of the first battery 220 is finished, the second battery The battery 240 may be charged. As a result, when both the first battery 220 and the second battery 240 cannot be fully charged, such as when there is not enough time, more power can be charged in the first battery 220. Therefore, it is possible to secure a large amount of power for the wireless communication device 110 to continue operating after the suspicious person removes the second battery 240.

  In addition, when the wireless communication device 110 is in the power supply simulated disconnection mode, if the attachment / detachment determination unit 280 determines that the second battery 240 or the dummy battery 250 is attached to the wireless communication device 110, the control unit 202 It is recommended to cancel the setting to the cutting mode. As a result, when a user accidentally removes the second battery 240 or the dummy battery 250, or when the second battery 240 or the dummy battery 250 is removed regardless of the user's intention, In the case where the two batteries 240 or the dummy battery 250 is not removed, when the user attaches the second battery 240 or the dummy battery 250 to the wireless communication device 110 again, the pseudo power-off mode is canceled and the normal mode ( Normal operating state). Therefore, the user can comfortably use the wireless communication device 110 again.

  In addition to the above case, when the user regains the wireless communication device 110 taken by the suspicious person, the user re-attaches the second battery 240 or the dummy battery 250 to the wireless communication device 110 so that the wireless communication device 110 110 is a normal mode. Therefore, the wireless communication device 110 can be used immediately, and it is possible to immediately report to the police etc. and request rescue.

  The detection unit 282 detects user input. Thereby, based on this detection, the control unit 202 can set the operation mode of the wireless communication device 110 to a security mode in which the security function of the wireless communication device 110 is activated. Therefore, when the user falls into a critical situation, the crime prevention function of the wireless communication device 110 can be reliably activated.

  In this embodiment, as the crime prevention function in the crime prevention mode, the voice output unit 208 outputs a warning sound (voice output) as described above. However, the present invention is not limited to this and is provided in the wireless communication device 110. Other members that are used may function.

  In the present embodiment, the detection unit 282 is a pin plug 282a (pin plug switch). When the user pulls the pin plug 282a and the pin plug 282a is detached from the wireless communication apparatus 110, the detection unit 282 detects the user's input. Therefore, the user input in the present embodiment is that the user removes the pin plug 282 a from the wireless communication device 110. However, the present invention is not limited to this, and the user input may be an input of a predetermined key operation of the operation unit 216 as described above. For example, a separate switch is provided outside the housing of the wireless communication device 110. The switch may be pressed.

  As in the present embodiment, the wireless communication device 110 includes the detection unit 282 and can set the operation mode of the wireless communication device 110 to the crime prevention mode based on the detection of the detection unit 282. If the attachment / detachment determination unit 280 determines that the second battery 240 or the dummy battery 250 is detached while in the crime prevention mode, the control unit 202 can take an operation pattern in which the operation mode is set to the power supply pseudo disconnection mode. As a result, the wireless communication device 110 can shift to the power supply pseudo disconnection mode after sufficiently exhibiting the security function mounted on the device itself in the security mode.

  In particular, in the state where the crime prevention function is operated in the crime prevention mode as in the above configuration, that is, the warning sound is output from the audio output unit 208, the power supply simulation is triggered by the detachment of the second battery 240 or the dummy battery 250. By shifting to the disconnection mode, it is possible to make a suspicious person think that “because the battery pack (second battery or dummy battery 250) has been removed, the power supply is disconnected and the warning sound has stopped sounding”. As a result, it is possible to avoid destruction of the wireless communication device 110 by a suspicious person and to perform (continue) a crime prevention function (speech input, imaging, wireless communication, GPS activation, etc.) in the pseudo power-off mode.

  Further, with the above configuration, when the second battery 240 or the dummy battery 250 is removed in the security mode, that is, in the normal mode, the wireless communication device 110 does not shift to the power supply pseudo disconnection mode. Therefore, since it is possible to avoid the unnecessary transition to the power-off pseudo-mode when the user is not in the security mode, that is, the user is not in a critical situation, the convenience of the wireless communication device 110 is not lowered.

  Further, as an operation pattern other than the above, the wireless communication device 110 may use the pseudo power-off mode even if the attachment / detachment determination unit 280 determines that the second battery 240 or the dummy battery 250 is detached when the device is in the crime prevention mode. You may continue the crime prevention mode without shifting to. As described above, the wireless communication device 110 is supplied with power from the first battery 220 when the second battery 240 is not attached, that is, when the second battery 240 is removed. For this reason, even after the second battery 240 is removed, the crime prevention mode can be continued and the crime prevention function can be sufficiently performed.

  The memory 284 includes a ROM, a RAM, an EEPROM, a nonvolatile RAM, a flash memory, an HDD, and the like, and stores a program processed by the control unit 202, communication data, and the like. The 284 can also store the sound input by the sound output unit 208 and the image captured by the image capturing unit 214 in the crime prevention mode or the power supply pseudo disconnection mode. In the present embodiment, the memory 284 also functions as the contact address registration unit 286.

  The contact registration unit 286 registers a communication device other than the wireless communication device 110 as the contact terminal 150. As a result, wireless communication with the contact terminal 150 via the base station 120 by the wireless communication unit 288, which will be described later, and transmission of position information to the contact terminal 150 by the transmission unit 292 can be performed. Therefore, the user of the contact terminal 150 can grasp the status of the user of the wireless communication device 110 and can take measures to rescue the user of the wireless communication device 110 as soon as possible.

  The wireless communication unit 288 establishes wireless communication with the base station 120 through a wireless communication method such as CDMA (Code Division Multiple Access) or WiMAX (Worldwide Interoperability for Microwave Access), and performs voice communication with a communication partner or a Web server. Perform data communication.

  When wireless communication unit 288 determines that second battery 240 or dummy battery 250 has been removed by a suspicious person and attachment / detachment determination unit 280 has detached second battery 240 or dummy battery 250 from its own device (wireless communication device 110). Wireless communication with the contact terminal 150 via the base station 120 may be started. More preferably, in the wireless communication, either one or both of the voice input by the voice input unit 206 and the image shot by the imaging unit 214 may be transmitted to the contact terminal 150. As a result, when the user of the wireless communication apparatus 110 falls into a critical situation, the input voice or captured image is transmitted to the contact terminal 150. Therefore, the user of the contact terminal 150 can grasp the situation where the user of the wireless communication device 110 is placed from the transmitted voice and image, and can take a corresponding action.

  For example, when the user of the wireless communication device 110 is a child, the parent wireless communication device may be registered as the contact terminal 150. Thus, when the child is attacked by a suspicious person and the second battery 240 or the dummy battery 250 of the child's wireless communication device 110 is removed, the input voice and the captured image are displayed on the parent wireless communication device (contact terminal 150). ). Therefore, the parent can determine the situation of the child based on the transmitted voice and image, and can take measures to ensure the safety of the child.

  The wireless communication with the contact terminal 150 may be a normal voice call transmission (calling) to the contact terminal 150, or an electronic mail transmission or a videophone call (calling) to the contact terminal 150. Etc.

  In the present embodiment, the wireless communication unit also functions as a transmission unit. The transmission unit 292 transmits the position of the wireless communication device 110 derived by the GPS reception unit 290 described later.

  When the attachment / detachment determination unit 280 determines that the second battery 240 or the dummy battery 250 has been detached from its own device (when the wireless communication device 110 is set to the power supply pseudo disconnection mode), the transmission unit 292 The derived position of the wireless communication device 110 may be transmitted to one or both of the contact terminal 150 and the server (relay server 140). Thereby, if the transmission part 292 transmits the position of the said radio | wireless communication apparatus 110 to the contact terminal 150, the user of the contact terminal 150 can grasp | ascertain the position directly. Further, if the transmission unit 292 transmits the position of the wireless communication device 110 to the server, the user of the contact terminal 150 can grasp the position by performing communication connection to the server. Therefore, in any case, the user of the contact terminal 150 can grasp the position of the wireless communication device 110.

  The GPS receiving unit 290 receives a signal from the GPS satellite 160 and derives the position of the wireless communication device 110 using the signal.

  When the attachment / detachment determination unit 280 determines that the second battery 240 or the dummy battery 250 is detached from its own device (when the wireless communication device 110 is set to the pseudo power-off mode), the GPS reception unit 290 determines that the wireless communication device The position 110 may be derived. As a result, the transmission unit 292 (wireless communication unit 288) can transmit the position of the own device to the contact terminal 150 or the server.

  As described above, the wireless communication apparatus 110 according to the present embodiment includes the first battery 220 that is invisible inside, can be mounted with the second battery 240, so-called battery pack or dummy battery 250, and is attached or detached. The unit 280 determines whether the second battery 240 or the dummy battery 250 is attached to or detached from the wireless communication device 110. When the suspicious person removes the second battery 240 from the wireless communication device 110, the attachment / detachment determination unit 280 does not attach the second battery 240 to the wireless communication device 110, that is, the second battery 240 is detached. Power is supplied from the first battery 220 to the wireless communication device 110. Thereby, since the power is not cut off even after the second battery 240 is removed, the wireless communication device 110 can continue to operate. Therefore, even after the second battery 240 is removed, the crime prevention function can be performed in the crime prevention mode and the power supply pseudo disconnection mode.

  In addition, since the wireless communication device 110 can continue to operate even after the second battery 240 is removed, the wireless communication device 110 such as the crime prevention mode and the power supply pseudo-disconnection mode is mainly used, that is, active crime prevention. In addition to the function, a person other than the user of the wireless communication apparatus 110 is the main body, that is, a passive crime prevention function can be exhibited. For example, it is possible to use a service or the like that searches for the position of the wireless communication device 110 that has become widespread in recent years using another communication device.

  FIG. 4 is a circuit diagram illustrating a configuration of an electric circuit of the wireless communication device 110. FIG. 4A shows a state in which neither the second battery 240 nor the dummy battery 250 is attached. FIG. 4B shows a state where the second battery 240 is attached. FIG. 4C shows a state in which the dummy battery 250 is attached. In FIG. 4, the flow of electricity in the circuit of the wireless communication device 110 is indicated by arrows. Explanation of elements not directly related to the present invention is omitted.

  As shown in FIG. 4A, when neither the second battery 240 nor the dummy battery 250 is attached to the wireless communication device 110, the battery attachment portion side positive power supply terminal 232 that is the power supply terminal of the battery attachment portion 230. The battery-side power supply terminal is not connected to any of the battery-attached-part-side negative power-feed terminal 234 and the battery-attached-part-side ID terminal 236. When the first switch 276 is turned on and the second switch 278 is turned off by the control unit 202, power is supplied from the first battery 220.

  As shown in FIG. 4B, when the second battery 240 is attached to the wireless communication device 110, the second battery side plus power supply terminal 242 and the second battery side, which are power supply terminals of the second battery 240, are provided. The negative power supply terminal 246 and the second battery side ID terminal 248 are connected to the corresponding power supply terminals of the battery mounting portion 230. When the second switch 278 is turned on and the first switch 276 is turned off by the control unit 202, power is supplied from the second battery 240.

  As shown in FIG. 4C, when the dummy battery 250 is attached to the wireless communication apparatus 110, the dummy battery side plus pseudo power supply terminal 252, dummy battery side minus pseudo power supply, which are the dummy power supply terminals of the dummy battery 250. The power supply terminal 254 and the dummy battery side ID terminal 256 are connected to the corresponding power supply terminals of the battery mounting portion 230. When the first switch 276 is turned on and the second switch 278 is turned off by the control unit 202, power is supplied from the first battery 220.

  Here, focusing on the resistance in the circuit shown in FIG. 4, a main body resistor 300 is provided in the circuit. The second battery 240 is provided with an ID resistor 240a, and the dummy battery 250 is provided with an ID resistor 250a. Therefore, the resistance in the circuit shown in FIG. 4A is only the main body resistor 300, and the resistance in the circuit shown in FIG. 4B is the main body resistor 300 and the ID resistor 240a. Further, the resistors in the circuit shown in FIG. 4C are the main body resistor 300 and the ID resistor 250a. As a result, the resistance measuring unit 270 measures the resistance value of the circuit, so that the attachment / detachment determining unit 280 determines whether or not the second battery 240 or the dummy battery 250 is attached to the own device. It is possible to determine which member is the second battery 240 or the dummy battery 250.

  For example, assuming that the resistance value indicated by the main body resistor 300 is 100 kΩ, the resistance value indicated by the ID resistor 240a is 100 kΩ, and the resistance value indicated by the ID resistor 250a is 10 kΩ, the resistance value of the circuit shown in FIG. The resistance value of the resistor 300), the resistance value of the circuit shown in FIG. 4B is 200 kΩ (the resistance value of the main body resistor 300 and the ID resistor 240a), and the resistance value of the circuit shown in FIG. And ID resistor 250a). Therefore, if the resistance value measured by the resistance measurement unit 270 is less than 110 kΩ, the attachment / detachment determination unit 280 can determine that nothing is mounted on the battery mounting unit 230, and the resistance value is 110 kΩ or more and less than 200 kΩ. If so, it can be determined that the dummy battery 250 is mounted on the battery mounting unit 230. If the resistance value is 200 kΩ or more, the second battery 240 is mounted on the battery mounting unit 230. Judgment can be made.

  Based on the above, the resistance values of the main body resistor 300 and the ID resistor 250a may be set to the first predetermined value, and the resistance values of the main body resistor 300 and the ID resistor 240a may be set to the second predetermined value. Accordingly, the attachment / detachment determination unit 280 can determine that nothing is attached to the battery attachment unit 230 when the resistance value measured by the resistance measurement unit 270 is less than the first predetermined value. When the value is less than the second predetermined value, it can be determined that the dummy battery 250 is attached to the battery attachment unit 230. When the resistance value is equal to or greater than the second predetermined value, the battery attachment unit 230 has the second battery. It can be determined that 240 is attached.

  In the present embodiment, the attachment / detachment determination unit 280 uses the resistance value to determine whether the second battery 240 or the dummy battery 250 is attached to or detached from the battery attachment unit 230 (wireless communication device 110). As a means, it is also possible to use the voltage or current of the electric power flowing through the resistance measuring unit 270.

  FIG. 5 is a flowchart showing the operation of the wireless communication apparatus 110. As shown in FIG. 5, when the wireless communication device 110 is turned on, the first switch 276 is first turned on (S <b> 400), and power is supplied from the first battery 220. Then, the resistance measuring unit 270 measures the resistance value (resistance value) inside the wireless communication device 110 (S402). Using the resistance value, the attachment / detachment determination unit 280 determines whether the second battery 240 or the dummy battery 250 is attached to or detached from the wireless communication device 110 (S404).

  When the resistance value is less than the first predetermined value (less than the first predetermined value in S404), the attachment / detachment determination unit 280 determines that neither the second battery 240 nor the dummy battery 250 is attached to the wireless communication device 110. Then, the fact is displayed on the display unit 204 to notify the user and prompt one of them to be worn (S406). Thereafter, when either the second battery 240 or the dummy battery 250 is mounted (YES in S408), the resistance measurement unit 270 measures the resistance value again (S404). When neither the second battery 240 nor the dummy battery 250 is mounted (NO in S408), the power supply from the first battery 220 is continued, and the control unit 202 intermittently checks the remaining power of the first battery 220. This is performed (S410).

  When the remaining amount of power of the first battery 220 is equal to or less than a predetermined amount, that is, when there is no (or almost no) remaining amount (NO in S410), that fact is displayed on the display unit 204 and The battery 220 is prompted to be charged (S412). When charging (YES in S412), a charging operation is performed (S414). When not charging (NO in S412), the power of the first battery 220 is consumed, and the operation of the wireless communication device 110 ends.

  When the resistance value is greater than or equal to the first predetermined value and less than the second predetermined value (the first predetermined value and greater than the second predetermined value in S404), the attachment / detachment determination unit 280 has the dummy battery 250 attached to the wireless communication device 110. Power supply from the first battery 220 is continued (S416).

  When the resistance value is equal to or greater than the second predetermined value (greater than or equal to the second predetermined value in S404), the attachment / detachment determination unit 280 determines that the second battery 240 is attached to the wireless communication device 110 (S418). Then, the control unit 202 turns off the first switch 276 and turns on the second switch 278 (S420), and power is supplied from the second battery 240 to the wireless communication device 110. Thereafter, the control unit 202 intermittently checks the remaining power of the second battery 240 (S422).

  When the remaining amount of power of the second battery 240 is equal to or less than a predetermined amount (a state where there is little or no remaining amount) (NO in S422), this is displayed on the display unit 204, and the user is charged with the second battery 240. (S424). When charging (YES in S424), a charging operation is performed (S412). When not charging (NO in S424), the second switch 278 is turned off, the first switch 276 is turned on (S426), and power is supplied from the first battery 220 to the wireless communication device 110.

  Thereafter, the control unit 202 intermittently checks the remaining power of the first battery 220 (S428). When the remaining amount of power of the first battery 220 is equal to or less than the predetermined amount, that is, when there is no (or almost no) remaining amount (NO in S428), that fact is displayed on the display unit 204 and The battery 220 is prompted to be charged (S412).

  In a state where the wireless communication device 110 is supplied with power from the first battery 220 (YES in S428) and is operating in the normal mode, the pin plug 282a is removed, so that the detection unit 282 receives user input (user In the state where power is supplied from the second battery 240 (YES in S422) and operating in the normal mode, the pin plug 282a is removed. When the detection unit 282 detects a user input (user critical situation) (YES in S432), the control unit 202 sets the operation mode of the wireless communication device 110 to the crime prevention mode (S434).

  When the crime prevention mode is set, the voice output unit 208 outputs a warning sound (S436). Then, the battery lid detection unit 272 intermittently detects whether or not the battery lid 260 is removed from the wireless communication device 110 (S438). When the battery lid detection unit 272 detects that the battery lid 260 has been removed from the wireless communication apparatus 110, that is, when the battery lid 260 is not present (YES in S438), the imaging unit 214 captures an image ( Imaging is started (S440).

  In the present embodiment, the image capturing by the imaging unit 214 is performed when the battery cover 260 is removed in the crime prevention mode. However, the present invention is not limited to this. May be. In this case, needless to say, the imaging start processing is included in the simulated power-off mode setting by a subroutine described later.

  When the pin plug 282a is reattached with the battery cover present (NO in S438) (YES in S442), the control unit 202 cancels the security mode of the wireless communication device 110 (S444), and sets the operation mode of its own device. Set to normal mode. If the pin plug 282a is not reattached (NO in S442), intermittent detection by the battery lid detection unit 272 is continued (S438).

  After the imaging unit 214 starts imaging (S440), the attachment / detachment determination unit 280 intermittently determines whether the second battery 240 or the dummy battery 250 is detached (S446). When the attachment / detachment determination unit 280 determines that the second battery 240 or the dummy battery 250 is detached (YES in S446), the control unit 202 sets the operation mode of the own device to the power supply pseudo disconnection mode (S448). Thereafter, when the second battery 240 or the dummy battery 250 is reattached to the wireless communication apparatus 110, that is, when the attachment / detachment determination unit 280 determines that the second battery 240 or the dummy battery 250 is attached to the own apparatus (YES in S450). The control unit 202 cancels the setting to the pseudo power-off mode (S452), and sets the operation mode of the own device to the crime prevention mode. When the second battery 240 or the dummy battery 250 is not reattached (NO in S450), the wireless communication device 110 consumes power in the power supply pseudo disconnection mode, and the operation ends.

  When the second battery 240 or the dummy battery 250 is not detached from the wireless communication device 110 (NO in S446), the battery cover detection unit 272 has attached the battery cover 260 to the wireless communication device 110 (reattachment). If it is detected (YES in S454), the control unit 202 cancels the security mode of the wireless communication device 110 (S444). When the battery cover 260 is not remounted (NO in S454), the intermittent detachment determination by the detachment determination unit 280 is continued (S446).

  In the present embodiment, when power is consumed in the crime prevention mode or the simulated power-off mode, the operation of the wireless communication device 110 ends. However, when the second battery 240 or the dummy battery 250 is mounted after the operation ends, or when the first battery 220 is charged and the wireless communication device 110 is turned on, the wireless communication device 110 operates. You may start as a normal mode, not a mode at the end, that is, a security mode or a pseudo power-off mode.

  Further, in the present embodiment, the operation pattern of the wireless communication device 110 shifts to the power supply pseudo disconnection mode when the second battery 240 or the dummy battery 250 is detached in the security mode. However, the present invention is not limited to this. Even after the second battery 240 or the dummy battery 250 is detached in the crime prevention mode, the crime prevention mode may be continued without shifting to the power supply pseudo disconnection mode. Further, when the second battery 240 or the dummy battery 250 is detached, the security mode may not be performed and the mode may be shifted to the power supply pseudo disconnection mode.

  FIG. 6 is a flowchart illustrating a charging operation of the wireless communication device 110. As shown in FIG. 6, when charging, the control unit 202 first determines whether or not the first switch 276 is on (S500). When the first switch 276 is not on (NO in S500), the control unit 202 turns on the first switch 276 (S502). If the first switch 276 is on (YES in S500) or if the first switch 276 is on (S502), the control unit 202 starts charging the first battery 220 (S504).

  When charging of the first battery 220 is completed, that is, when the first battery 220 is fully charged (YES in S506), the resistance measuring unit 270 measures the resistance value (resistance value) inside the wireless communication device 110 ( S508). Using the resistance value, the attachment / detachment determination unit 280 determines whether the second battery 240 or the dummy battery 250 is attached to or detached from the wireless communication device 110 (S510).

  When the resistance value is less than the first predetermined value (less than the first predetermined value in S510), the attachment / detachment determination unit 280 has neither the second battery 240 nor the dummy battery 250 attached to the wireless communication device 110 (attachment). (No) (S512). When the resistance value is greater than or equal to the first predetermined value and less than the second predetermined value (the first predetermined value is greater than or equal to the second predetermined value in S510), the attachment / detachment determination unit 280 attaches the dummy battery 250 to the wireless communication device 110. (S514). In these cases, the control unit 202 ends the charging operation.

  When the resistance value is equal to or greater than the second predetermined value (greater than or equal to the second predetermined value in S510), the attachment / detachment determination unit 280 determines that the second battery 240 is attached to the wireless communication device 110 (S516). In this case, the control unit 202 turns off the first switch 276, turns on the second switch 278 (S518), and starts charging the second battery 240 (S520). When charging of the second battery 240 is completed, that is, when the second battery 240 is fully charged (YES in S522), the control unit 202 ends the charging operation.

  FIG. 7 is a flowchart showing the setting operation and the releasing operation of the power supply pseudo disconnection mode. FIG. 7A shows the setting operation of the power supply pseudo disconnection mode, and FIG. 7B shows the release operation of the power supply pseudo disconnection mode.

  When setting the operation mode of the wireless communication device 110 to the pseudo power-off mode, as shown in FIG. 7A, the control unit 202 first stops the output of the display unit 204 and the audio output unit 208 (the output is changed). If not, the operations of the light emitting unit 210 and the vibration output unit 212 are invalidated (S600). Then, the control unit 202 starts voice input by the voice input unit 206 (S602), and starts wireless communication with the contact terminal 150 via the base station 120 by the wireless communication unit 288 (S604). Thus, the input voice and the photographed image are transmitted to the contact terminal 150.

  In parallel with the above, the control unit 202 activates the GPS receiving unit 290 (S606), and the GPS receiving unit 290 receives a signal from the GPS satellite 160 and derives the position of the wireless communication device 110. Next, the control unit 202 activates the transmission unit 292 and transmits the position information (position information) derived by the GPS reception unit 290 to the contact terminal 150.

  As described above, in the present embodiment, when the pseudo power-off mode is set, the operation of the display unit 204, the audio output unit 208, the light emitting unit 210, and the vibration output unit 212, that is, the appearance, the power is turned off when activated. All actions that seem to have not been disabled have been disabled (output stopped), but this is not a limitation. In such a simulated power-off mode, at least the output of the display unit 204 and the audio output unit 208 may be prevented.

  In this embodiment, sound, images, and position information are transmitted to the contact terminal 150. However, the present invention is not limited to this, and may be transmitted to the server or both the contact terminal 150 and the server. Alternatively, the user may be transmitted to an organization that can rescue the user, such as a security company.

  Further, in the present embodiment, in the pseudo power-off mode, voice input by the voice input unit 206, wireless communication with the contact terminal 150 by the wireless communication unit 288 via the base station 120, and the position of the own device by the GPS reception unit 290 are provided. A plurality of operations such as derivation are performed, but the present invention is not limited to this. In the pseudo power-off mode, one or more of the above operations may be performed. For example, if only the position of the device itself is derived by the GPS receiver 290 and the position is transmitted by the transmitter 292, the power consumption can be reduced and the operation can be performed for as long a time as possible. It becomes.

  When returning the operation mode of the wireless communication apparatus 110 to the normal mode, that is, when canceling the power supply pseudo disconnection mode, as shown in FIG. 7B, the control unit 202 first stops the output in the power supply pseudo disconnection mode setting. The stopped function is released, and the invalidated operation is validated, that is, the invalidation is released (S650). Next, the control unit 202 ends the wireless communication of the wireless communication unit 288 (S652), and stops the voice input by the voice input unit 206 (S654). Then, the control unit 202 stops imaging by the imaging unit 214 (S656), stops transmission of position information by the transmission unit 292 (S658), and stops reception of signals and position derivation by the GPS reception unit 290 (S660). .

  As described above, the wireless communication apparatus 110 according to the present embodiment includes the first battery 220 and the second battery 240 or the dummy battery 250, and the first battery when the second battery 240 or the dummy battery 250 is detached. Power is supplied from 220. Thereby, it becomes possible to continue to operate even after the second battery 240 or the dummy battery 250 is removed. And if the 2nd battery 240 or the dummy battery 250 is removed by a suspicious person, it will become possible to fully exhibit a crime prevention function by shifting from a normal operation mode to a crime prevention mode or a power supply pseudo-disconnection mode.

  Further, by attaching the second battery 240, which is a secondary battery, to the wireless communication device 110, it is possible to extend the startup time of the wireless communication device 110. Further, since the first battery 220 is invisible, the suspicious person who has removed the second battery 240 or the dummy battery 250 thinks that the power supply source of the wireless communication device 110 has been removed, and the wireless communication is performed. Attention to the device 110 can be diverted.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  Note that each step in the wireless communication method of the present specification does not necessarily have to be processed in time series in the order described in the flowchart, and may include processing in parallel or a subroutine.

  The present invention can be used for a wireless communication apparatus having a crime prevention function.
