  Hereinafter, embodiments of a security system and a program thereof according to the present invention will be described in detail with reference to the accompanying drawings. 1 to 6 show an embodiment of a security system and its program according to the present invention.

  FIG. 1 is a diagram showing a schematic configuration of a security system according to a first embodiment of the present invention. As shown in FIG. 1, a security system according to a first embodiment of the present invention includes a mobile phone 10, a reader / writer 11 mounted on the mobile phone 10, and portable items (a bag, a notebook, a key holder, a wallet). Etc.) and an IC tag (IC seal) 21 attached or attached to 20.

  The mobile phone 10 is a mobile phone (including a PHS machine) equipped with a normal transmission / reception function, and includes a display unit and an operation unit. The mobile phone 10 downloads an application program for using the system from a Web site connected via the Internet network and controls various operations.

The reader / writer 11 is externally attached to the mobile phone 10 and is operated by power supplied from the mobile phone or a battery mounted on the external reader / writer, and communicates with the IC tag 21 at predetermined intervals by radio. Has the ability to do.
Note that the reader / writer 11 is not limited to being externally attached, and may be built in the mobile phone 10 in advance. The communicable distance between the reader / writer 11 and the IC tag 21 is about 5 m.

  The IC tag (IC seal) 21 is used by being affixed to the portable product 20 and operates by receiving radio waves in a specific frequency band. The IC tag 21 includes a CPU 211, a ROM 212, a RAM 213, an EEPROM 214, a coprocessor (coprocessor) 215, and an I / F (interface) 216 formed as an IC chip, and an antenna ( Loop antenna) 217 is provided. Note that the configuration of the IC tag is not necessarily limited to the above configuration.

  The IC tag 21 is given a unique identification number (serial number) that cannot be tampered in advance in the manufacturing stage, or is left blank in the manufacturing stage and is arbitrarily set later. The individual data of the portable product is written by the user from the operation unit of the mobile phone 10 via the reader / writer 11. The data written here is not limited to the above, and user information such as the user's address, name, and contact information can also be written.

  The number of IC tags 21 is not limited to one, and a plurality of IC tags 21 may be provided. The IC tag 21 has been described as having a card shape. However, the IC tag 21 can be appropriately used for a label type, a coin type, a stick type, and the like, and is not particularly limited.

  FIG. 2 is a flowchart showing an initial setting operation when the security system according to the first embodiment of the present invention is used. First, a user (hereinafter referred to as a user) of this system attaches or attaches an IC tag 21 to a portable product (for example, a bag) 20 and attaches a reader / writer 11 to a user-owned mobile phone 10. (Step S1).

  Next, the user launches an IC tag initial setting screen from the operation menu of the mobile phone 10 (step S2). The user registers user information (name, address, contact information, etc.) using the operation unit (step S3), and then associates the portable product 20 with data (for example, data indicating that the portable product is a bag). Registration is performed (step S4), and the initial setting process is terminated. The data initialized here is written into the EEPROM 214 of the IC tag 21 by wireless communication via the reader / writer 11. At this time, if there are IC tags that are not to be written, these are set outside the radio wave range of the write radio waves.

For example, when the IC tag is attached to each of “bag”, “wallet”, and “periodic case”, the association data written to the IC tags 21a to 21c is the following data. <No .-------------> is an identification number unique to each IC tag that cannot be tampered with.
(1) IC tag 21a <No.000000002043003> = bag (2) IC tag 21b <No.000000002043004> = wallet (3) IC tag 21c <No.000000002043005> = periodic insertion

The EEPROM 214 into which these data are written is an electrically rewritable recording medium. Therefore, even if the data has been set by the initial setting process once, it has been erased again via the mobile phone 10 and then renewed. It is also possible to set the association data for portable items. In addition, the timing at which the association is performed is arbitrary. For example, registration at a destination is possible, and furthermore, the registered association data can be deleted or changed.
In addition, user information and association data registered using the operation unit of the mobile phone can be stored and managed in the memory on the mobile phone side without being written in the IC tag itself.
Further, the association data registered in advance can be used for belonging registration processing for the day by reading an IC tag attached to the belonging by the reader / writer 11 when going out.

  FIG. 3 is a sequence chart showing an operation example of the security system according to the first embodiment of the present invention. First, the mobile phone 10 to which the reader / writer 11 is attached transmits a confirmation signal to the IC tag 21 attached to the portable product 20 via the reader / writer 11 (step S11). After transmitting the confirmation signal to the IC tag 21 via the reader / writer 11, the mobile phone 10 counts the interval until the response signal from the IC tag 21 is received by the timer function.

When the IC tag 21 receives the confirmation signal transmitted via the reader / writer 11, the IC tag 21 transmits a response signal (step S12). When receiving the response signal from the IC tag 21, the mobile phone 10 stops counting by the timer function, and then counts a predetermined time until the confirmation signal is transmitted to the IC tag 21 by the timer function.
The communication interval between the mobile phone 10 on which the reader / writer 11 is mounted and the IC tag 21 can be arbitrarily changed by the user.

  While the response signal from the IC tag 21 is returned, that is, when the mobile phone 10 is in a communicable state with the IC tag 21, the mobile phone 10 repeats the process of step S 11. The IC tag 21 transmits a response signal every time a confirmation signal transmitted via the reader / writer 11 is received (step S12).

  When the interval until the mobile phone 10 receives the response signal by the timer function after transmitting the confirmation signal to the IC tag 21 via the reader / writer 11 exceeds the predetermined value (communication impossible state), the IC 10 It is determined that there is no response signal from the tag 21 (step S13), and the user is notified of the first alarm (that the portable product 20 has been forgotten) (step S14).

  When the user is notified of the first alarm via the mobile phone 10, the user goes to a place where he / she has misplaced the mobile device 20 while holding the mobile phone 10 with the reader / writer 11 attached. Search for 20. Note that the user does not necessarily need to search for the portable item 20 immediately after the first alarm is notified, and may search for the location of the portable item 20 at an arbitrary timing.

  After notifying the user of the first alarm, the mobile phone 10 transmits again a confirmation signal to the IC tag 21 via the reader / writer 11 at regular intervals (step S15), and the response signal from the IC tag 21 is transmitted. The presence or absence is confirmed (step S16). In step S16, when there is no response signal from the IC tag 21 (no response), the first alarm is notified again (step S14).

  When the user moves to the vicinity (communication enabled state) of the portable item 20 left behind while holding the mobile phone 10 with the reader / writer 11 attached, the IC tag 21 is transmitted via the reader / writer 11. A response signal to the confirmation signal is transmitted (step S17).

  When the mobile phone 10 receives the response signal from the IC tag 21 in step S16 (there is a response), the mobile phone 10 gives the user a second alarm different from the first alarm (that there is a forgotten item <portable item 20> in the vicinity). Notification is made (step S18).

  Here, the alarm is one of sound (incoming melody) / light emission / vibration (vibration function) / character / image, or a combination thereof. For example, when setting a sound as an alarm, it is possible to select and set a user-desired sound type, for example, as an incoming melody downloaded from a website, or by a sound recorded by itself, Or you may make it reproduce | regenerate the message which input the character using an automatic audio | voice reproduction | regeneration function.

  Further, the first alarm and the second alarm may be different from each other, and in the case where a ring tone is set, different sound types may be used. Furthermore, it is optional to set the first alarm as sound and the second alarm as light emission or vibration, and to make the first alarm and the second alarm the same.

Furthermore, when setting a character or an image as an alarm, for example, an image indicating a letter and a wallet such as “I forgot my wallet!” As a first alarm and “Found!” As a second alarm. Etc. can be notified as an image. Such an image can also be an image downloaded from a website. Note that the various settings described above can be arbitrarily changed by the user from the screen of the portable information terminal, and each item (target) can be changed. A separate alarm can also be set for this, and is not particularly limited.

  These first alarm and second alarm can be notified regardless of whether or not a call is in progress. For example, when a call is in progress, it is preferable to notify by an interrupt display or a voice alarm.

  As described above, the communicable distance between the reader / writer 11 and the IC tag 21 is about 5 m. Therefore, the user can recognize that the misplaced portable product 20 exists at a distance of about 5 m (within a radius of about 5 m) from the current position.

  According to the first embodiment of the present invention, a security system can be easily constructed by attaching or attaching a non-contact type IC tag to a portable product and attaching a reader / writer to a cellular phone.

  The IC tag receives a confirmation signal transmitted from the reader / writer 11 attached to the mobile phone, converts the received confirmation signal (wireless radio wave) into electric power, and drives the IC chip to respond. Since a signal can be transmitted, there is no need to mount a power source. Therefore, there is no problem that the system cannot be used due to battery exhaustion as in the conventional case.

  Furthermore, in the first embodiment of the present invention, the mobile phone 10 is provided with a function for measuring the strength of the signal (response signal) returned from the IC tag 21, and the response signal reception strength at the time of searching for the misplaced portable product 20. Based on the above, it may be controlled to automatically change the ring volume, the light emission pattern, the vibration pattern, and the like. This control mode automatically switches the mode after notifying the second alarm as an application program of the mobile phone 10 even if the user himself / herself sets the mode switching from the operation unit of the mobile phone after notifying the second alarm. May be performed. Further, the communicable distance between the reader / writer 11 and the IC tag 21 can be switched to, for example, two modes of about 5 m mode and about 10 cm mode, and the approximate search range of the portable product 20 is set in the about 5 m mode. You may make it recognize and switch to about 10 cm mode, and may make it specify the position of the portable article 20.

  The above-described mode is an example and does not limit the communicable distance. For example, when a mode switching mechanism that can be set in multiple stages is provided, the mode can be arbitrarily set by the user. .

  The communication between the IC tag and the reader / writer can be temporarily canceled by a user's arbitrary operation (for example, turning off the power or ending the search operation). The system is automatically activated when the permitted operation (such as the start of an exploration operation or the start of a warning operation) or in the case of a warning operation, the IC tag and the reader / writer again reach a communicable distance It may be.

  Further, in the case of the search operation, the confirmation signal transmitted from the reader / writer for confirming the communication state between the reader / writer and the IC tag is a timing arbitrarily set by the user via the operation unit of the portable information terminal. You may make it transmit with. For example, communication is performed once every time a search switch (for search operation start) provided in an operation unit of a mobile phone is turned on. In this example, for example, it is only necessary to turn on the switch after moving to each room or the like. Therefore, although the number of times of pressing the switch is increased, it can be expected that the power consumption can be suppressed. Of course, it goes without saying that it may be transmitted constantly.

  FIG. 4 is a diagram showing a schematic configuration of a security system according to the second embodiment of the present invention. In FIG. 4, in addition to the configuration of the first embodiment of the present invention described above, the security system according to the second embodiment of the present invention is equipped with a GPS function in the mobile phone 10, and further includes a base station 30, And a GPS satellite 40 that communicates with the base station 30.

  Similar to the first embodiment, the mobile phone 10 has a normal communication function and includes an operation unit and a display unit, but is newly equipped with a GPS function.

  The GPS function is a function for detecting self-location information of the mobile phone 10. Normally, when detecting the self-location information of the mobile phone 10, a GPS signal is transmitted from the mobile phone 10 by a predetermined operation, and after accessing the base station 30 from the mobile phone 10 via the wireless communication network, the self-location information Send detection request. When the GPS satellite 40 catches the GPS signal transmitted from the mobile phone 10, the GPS satellite 40 transmits position information (latitude, longitude, altitude) of the mobile phone 10 to the base station 30. The base station 30 transmits the position information transmitted from the GPS satellite 40 to the mobile phone 10 as address information or map information, for example. As described above, the self-location information of the mobile phone 10 can be acquired.

  In the second embodiment of the present invention, when the reader / writer 11 and the IC tag 21 cannot communicate with each other, the self-location information of the mobile phone 10 (with the reader / writer 11 attached) is obtained by the GPS function. The location information is obtained and notified to the user via the mobile phone 10.

  FIG. 5 is a sequence chart showing an operation example of the security system according to the second embodiment of the present invention. First, the mobile phone 10 to which the reader / writer 11 is attached transmits a confirmation signal to the IC tag 21 as in the first embodiment (step S21).

  When the IC tag 21 receives the confirmation signal transmitted via the reader / writer 11, the IC tag 21 transmits a response signal (step S22).

  Note that a response signal is returned from the IC tag 21 in response to the confirmation signal transmitted via the reader / writer 11, and the response signal can be received by the reader / writer 11, that is, in a communicable state. The processes in steps S21 and S22 are repeated.

  Here, a case where communication between the reader / writer 11 and the IC tag 21 becomes impossible will be described. The mobile phone 10 again transmits a confirmation signal to the IC tag 21 (step S23).

  However, when the portable product 20 with the IC tag 21 attached or attached is left behind and in a state where communication is impossible, the IC tag 21 sends a confirmation signal transmitted via the reader / writer 11. Since it cannot be received, a response signal cannot be transmitted.

  Therefore, the mobile phone 10 determines that there is no response signal when the interval until the response signal from the IC tag 21 is received by the timer function after transmitting the confirmation signal via the reader / writer 11 exceeds a predetermined value. (Step S24), a GPS signal is transmitted by the GPS function (Step S25), and an acquisition request for self-location information is transmitted to the base station 30 (Step S26).

  The base station 30 acquires position information (latitude, longitude, altitude) of the mobile phone 10 through communication with the GPS satellite 40 (step S27), and transmits the acquired position information to the mobile phone 10 (step S28). .

  When the mobile phone 10 acquires the position information transmitted from the base station 30, the mobile phone 10 displays the acquired position information and the time information at which the position information is acquired on the screen (step S29).

  Further, regarding the position information acquisition process of the mobile phone 10, the user does not need to perform a special process, and the acquisition process may be automatically performed by performing mode setting or the like in advance.

  In addition, since acquisition of position information is greatly influenced by the radio wave environment, the position information acquisition timing is acquired immediately after the radio wave environment is good when communication with the IC tag 21 becomes impossible. If the radio wave environment is bad, it is better to shift the timing and acquire it when it is good.

FIG. 6 is a diagram showing a display screen example of position information and time information displayed on the display unit of the mobile phone.
In the case of FIG. 6A, what is forgotten (bag), where it is forgotten (address display), and what time it was forgotten (time display) is displayed as “forgotten thing information”. In this case, all are displayed as character information.
Further, in the case of FIG. 6B, where the user forgets (map display), what is forgotten (wallet), and what time forget (time display) is displayed. In this case, the map information is displayed graphically, and other information is displayed as character information.
Note that the display can be performed regardless of whether or not a call is in progress. For example, when a call is in progress, forgetfulness information may be notified by performing an interrupt display or a voice alarm.

  According to the second embodiment of the present invention, when the reader / writer 11 and the IC tag 21 become unable to communicate, the position information is acquired using the GPS function of the mobile phone 10 and the acquisition is performed. By displaying the obtained position information on the mobile phone 10, the user can easily grasp the position information where the forgotten item exists.

  Further, in the second embodiment of the present invention, the method using the GPS function for obtaining the position information is shown, but the present invention is not limited to this.

  For example, as shown in FIG. 7, a radio wave is transmitted from the mobile phone 10 at regular intervals, and the rough location information of the mobile phone 10 is obtained from the received intensity between a plurality of base stations 31 to 33 that have caught the radio wave. A method such as detection is also possible. In this case, position information calculation processing based on signal strength between a plurality of base stations (31 to 33) may be performed by the server 50 connected to the mobile phone 10 via the Internet. When detecting the self-location information, the mobile phone 10 accesses the server 50 to acquire the location information.

  The above-described embodiments are preferred embodiments of the present invention, and various modifications can be made without departing from the spirit of the present invention.

  For example, it is possible to adopt a configuration in which the first embodiment and the second embodiment of the present invention are combined. In this case, the first alarm is notified at the time when there is a forgotten thing (communication between the reader / writer 11 and the IC tag 21 is impossible). Next, the position information of the mobile phone 10 is displayed on the display unit by the GPS function, and when the user goes to search for forgotten things based on the position information, the reader / writer 11 and the IC tag 21 can communicate with each other. It is also possible to notify the second alarm.

  Also, information (user information, portable product association data, etc.) written to the IC tag 21 at the time of initial setting is registered in a server of a third party connected via a communication network, for example, a station It can also be used as authentication information when handing over lost items in public organizations such as police.

  In addition, although the above-described embodiment has been described on the assumption that the portable item is forgotten, there is a possibility of being stolen especially in the case of a wallet or the like, so an IC tag is attached or attached to the wallet. It is possible to search for a wallet using this system even if it is stolen.

  Also, by attaching an IC tag to items carried by children (for example, name tags, shoes, clothes, etc.), you can prevent the situation of getting lost, or if you get lost, It is possible to search easily using this system.

  In addition, in the case of a tour trip accompanied by a tour attendant, by attaching an IC tag to the tourist's tour badge, etc., an alarm sounds when someone is far away and the name is displayed, It can also be used for confirming the number of people by a tour operator or searching for a stray person.

  Further, according to the present system, even if the mobile phone is left behind, if the article with the IC tag attached is carried, the communication between the mobile phone (reader / writer) and the IC tag is impossible ( Since the mobile phone rings, emits light, or vibrates, it is possible to immediately recognize that the mobile phone has been left behind.

  Furthermore, by attaching an IC tag to the product displayed in the store in advance so that the store clerk owns the mobile phone, and performing an association process with the IC tag attached to the product before opening the store Application as a shoplifting prevention system is also possible. When the store space is large, the association process between the product and the IC tag may be performed in a plurality of times.

  As a third embodiment of the present invention, the server shown in FIG. 7 can be used as an operation server for operating the security systems shown in the first and second embodiments described above. For example, information written to an IC tag (IC sticker) at the time of initial setting is registered in the operation server via a communication line (such as the Internet), or an identification number unique to the IC tag and personal information and association at the time of initial setting Data is managed by the operation server, and the alarm server and the position information at the time of the loss of the item are automatically or manually simultaneously with the occurrence of the loss of the item with the IC tag attached or after a certain period of time. Send it to and register it. By doing so, it becomes possible to access from other mobile phones other than the mobile phone owned by the lost person (user) itself or a PC or mobile terminal in an environment where the operation server can be accessed. The current state can be confirmed using a website (program) provided by the system operating company. When a lost item is found, the operation server is notified automatically or manually that it has been reacquired.

The user receives an IC tag from the system operating company in advance, and registers personal information (address, name, contact information, password, etc. as owner information) in the operation server as described above. As described above, a different serial number is assigned to each IC tag as described above, and a contact information of the system operating company, URL that is access information to the operation server, and the like are recorded.
The contact information may be written later so that the person who finds the lost item can visually confirm the information, or may be displayed on the surface of the IC tag by bar code display or printing. As a result, the person who finds the lost item can read the URL information of the operation server printed on or recorded on the IC tag attached to the lost item, the contact information of the system operating company, etc. as a reader / writer or barcode reader. Or by using a character reading function such as OCR, etc., and can easily access the system operation side to notify the notification of lost items.
Note that it is not always necessary to access and report a program provided by the system operating company. If the owner can be directly accessed, direct communication (such as telephone contact) may be performed. Requests to the discoverer of the lost item (contact with the program, direct contact with the person, disposal of found items, etc.) can be set in advance when the association data is registered.

  The operation server on the system operation side, when information on lost items is delivered, provides information on lost item detection to the user who owns the lost items, and details on the setup for delivery etc. Can be determined. In this case, it is possible to make arrangements for sending lost items to the owner, or to instruct the user to dispose of lost items if they are not needed.

  In the third embodiment, a case where a third party picks up a lost item is shown. For example, a device having a function similar to a reader / writer function capable of communicating with an IC tag is previously set in each place (in a building or in a town). It is possible to configure not only for mere loss but also for cases such as theft. In this case, for the information detected by the reader / writer, the information regarding the lost item is immediately transmitted to the operation server, and the user who is the owner is notified.

  Also, the system operation side can use the operation server to launch a bulletin board corner on the Web and post lost item inquiry information from the user who lost the article. In this case, the system operation side searches whether there is a report of lost items corresponding to the written information. To contact.

  Furthermore, when a crime such as kidnapping occurs, not only for a lost child, an exploration request is sent from the guardian to the operation server, and it is attached to the belongings worn by the person who became the lost or kidnapped party A mobile information terminal owned by each member who delivers the serial number of the IC tag and searches from the operation server by a reader / writer function installed in various places of public institutions, or who registers for a program It is also possible to send a search request to the server, perform a lost child / kidnapping search in the search mode, and issue a warning or send discovery location information to the operation server when it is found.

Furthermore, if the mobile phone itself is lost (communication with other associated items is impossible), the lock function is automatically activated after a certain period of time to prevent unauthorized use of the mobile phone by the finder. Control is performed in this way. In this case, the contact information of the system operating company is displayed on the screen of the mobile phone, and the position information and time information are transmitted at regular intervals. Therefore, the unauthorized use by the finder can be prevented, and the user can separately check the location information of the mobile phone by accessing the operation server.
Regarding the use of such a system, it is possible to distribute a CD-ROM or the like on which an application program is recorded by a method such as marketing or selling on the net.
