Description

  The present invention relates to a position information tracking system using an electronic tag, and in particular, by using a function of an electronic tag, it is possible to reliably move an article or a person later without using a special system such as a GPS function. The present invention relates to a position information tracking system using an electronic tag having a characteristic configuration for tracking.

  In recent years, various IC tag systems have been developed by applying an IC reader system that attaches an electronic tag, that is, an IC tag to an article and reads the IC tag information.

  For example, a product display location notification system has been known in which, when a customer approaches a store that stocks the desired product, the mobile phone of the customer is notified of information indicating that the desired product is in stock. (For example, refer to Patent Document 1).

  This system can specify detailed product identification information such as the product name, model number, size, and color of the desired product, for example, information such as the product number described in the catalog. is there.

Apart from this, provision of a “commuting mobile phone” that can check whereabouts and attendance of children using an au (registered trademark) mobile phone has been started (for example, see Non-Patent Document 1).
The “commuting mobile phone” is a device that utilizes the high-accuracy GPS function unique to an au (registered trademark) mobile phone, and acquires position information using GPS outside the school site or school building.

In addition to GPS, in a building such as a school building, the position is identified using the Bluetooth information sign infosign R (registered trademark), thereby accurately detecting an area unit having a radius of about 10 m. It is possible to manage in a wide range and finely.
Thereby, the place of the child who is going to school can be confirmed without being limited to the school, and the child can be safely sent to the school.

  In this case, since the BREWR (registered trademark) application installed on the mobile phone of the child automatically acquires the location information during school attendance according to the school's attendance / dismissal time and attendance status, bring the mobile phone. The operation from the side of the child is no longer necessary.

  Parents and teachers can access the dedicated website from a PC (personal computer) or mobile phone in an Internet connection environment and easily check the current location of the child. It also has a mail delivery function for correspondence.

For example, as current position confirmation, by acquiring position information automatically transmitted from a mobile phone possessed by a child, the current position of the child can be confirmed in real time from a dedicated Web screen or a mobile phone.
Also, by using the center push function, parents and teachers can easily check the current position of the child at any time.

In addition, school attendance / schooling / automatic notification function to notify parents / schools via email to the parents / schools in real time via the Internet, and the attendance status for each class can also be confirmed using a dedicated web screen. Attendance management function that can be received, help call function that receives a help call from a child and notifies a registered e-mail address as a notification destination in advance, and distributes crime prevention information to registered e-mail addresses such as schools and parents It also has a security information distribution function and a contact network function for accessing a class contact network from a dedicated Web screen.

However, in a system that obtains information about your child using the mobile phone service as described above,
A. GPS signal can be received by mobile phone,
B. C. that the mobile phone is powered on; There is a problem that the location information cannot be obtained unless the requirements A to C for the telephone communication area are satisfied.

  That is, for example, in the case of a child kidnapping case, it is highly likely that the kidnapper will turn off the mobile phone because the gait can be found on the mobile phone, and even if the mobile phone is still on, If you go out of the room, the position will not be known, and in these situations, the position of the child cannot be detected.

  Accordingly, an object of the present invention is to make it possible to track location information of a management target person such as a child even if the mobile phone is in a situation where communication is impossible without depending on the GPS function or the like. To do.

FIG. 1 is a block diagram showing the principle of the present invention, and means for solving the problems in the present invention will be described with reference to FIG.
See FIG. 1 In order to solve the above-mentioned problem, the present invention is an electronic tag system, which is a fixed electronic tag 2 installed on a fixed object 1 and a reader function that records an identification number and generates an electromagnetic wave 6. And a mobile electronic tag 4 having a battery and a terminal electronic tag reader of the mobile communication device terminal 5. The mobile communication device terminal 5 keeps the mobile electronic tag 4 and the mobile communication device terminal 5 constant. When the communication between the mobile communication device terminal 5 and the mobile electronic tag 4 is interrupted, the mobile electronic tag 4 generates an electromagnetic wave 6 using a built-in battery as a power source, and the identification number Is transmitted to the fixed electronic tag 2.

By configuring such a system, it is installed on a telephone pole, a traffic signal, or a fixed object 1 such as a traffic sign in the calling area of the mobile communication device terminal 5 such as a mobile phone without depending on the GPS function or the like. Since the identification number is recorded on the fixed electronic tag (IC tag) 2 that has been made, it is possible to track the gait later.
The moving body 3 in this case is typically a human being such as a schoolchild, but is also applied to pets.

  In this case, it is desirable that the mobile communication device terminal 5 is provided with a tracking release key, and the communication function between the mobile communication device terminal 5 and the mobile electronic tag 4 is temporarily stopped by pressing the tracking release key. Thereby, since the electromagnetic wave 6 is not generated from the mobile electronic tag 4 by using the battery as a power source, the battery consumption of the mobile electronic tag 4 can be prevented and unnecessary information can be prevented from being transmitted.

  In this case, when a predetermined time (for example, 24 hours) elapses after the tracking release key is pressed, the mobile electronic tag 4 generates the electromagnetic wave 6 by using the battery built in as a power source, and the identification number is set. It is desirable to configure to transmit to the fixed electronic tag 2.

  Normally, it is impossible to turn off the tracking release key for a long time. Therefore, if the security is released for a long time, there is a high possibility that the case has been involved in the incident. By functioning to transmit information, it is possible to automatically recognize the occurrence of an incident and start tracking.

  When communication between the mobile communication device terminal 5 and the mobile electronic tag 4 is interrupted and communication between the mobile communication device terminal 5 and the mobile electronic tag 4 is resumed, the mobile electronic tag 4 It is desirable that the generation of the electromagnetic wave 6 is stopped so that the battery consumption of the mobile electronic IC tag can be prevented and unnecessary information can be prevented from being transmitted.

  The fixed electronic tag 2 is preferably configured to obtain power from the electromagnetic wave 6 transmitted from the mobile electronic tag 4 and record the identification number transmitted from the mobile electronic tag 4, thereby Since there is no need to mount a battery on the fixed electronic tag 2, the net of the fixed electronic tag 2 can be stretched at a very low cost.

The information recorded in the fixed electronic tag 2 is preferably erased after a predetermined period of time has elapsed, thereby reducing the capacity of the memory mounted on the fixed electronic tag 2, for example, 64 kbit. It can be suppressed to the extent.
When the upper limit of writing is reached, it may be configured to overwrite the past data.

  Further, it is desirable that an encryption code is required when reading the information recorded on the fixed electronic tag 2, so that an ordinary person such as an eavesdropper cannot collect data, and the encryption code Since only the police / administrative organization that holds the data reads the recorded information, it becomes possible to protect the privacy of the individual.

  In addition, the fixed electronic tag 2 may be configured to be able to record the transmission date and time together with the identification number transmitted from the mobile electronic tag 4, thereby determining the route of movement. It becomes possible to do.

  Other system configurations include a fixed electronic tag reader installed on the fixed object 1, an information network that extracts information from the fixed electronic tag reader, a management server that manages the obtained information, and an identification number. Is recorded, and the mobile electronic device terminal 5 is connected to the mobile electronic device terminal 5. The mobile electronic device terminal 5 is connected to the mobile electronic device tag 4 and the mobile electronic device terminal 5 with a certain amount. When the communication between the mobile communication device terminal 5 and the mobile electronic tag 4 is interrupted, information is transmitted from the mobile communication device terminal 5 to the management server and specified from the reader for the fixed electronic tag. It may be configured to read only information of the mobile electronic tag 4 containing the identification number.

  With this configuration, it is possible to obtain information on the mobile electronic tag 4 in real time, and since no useless information is collected, it is possible to collect information without applying a line load.

  In this case, after communication between the mobile communication device terminal 5 and the mobile electronic tag 4 is interrupted, when communication between the mobile communication device terminal 5 and the mobile electronic tag 4 is resumed, the mobile communication device terminal 5 It is desirable that the information is transmitted from the management server to the management server, and the information collection of the mobile electronic tag 4 containing a specific identification number is preferably stopped, thereby avoiding the collection of useless information. it can.

  The fixed electronic tag reader reads information stored in the mobile electronic tag 4 from the communication range, compares the read information with the information to be obtained, and only matches the information to be obtained. It is desirable to store the read information in the memory unit of the tag reader, thereby avoiding unnecessary collection of information.

  In addition, the mobile communication device terminal 5 is provided with a tracking release key, and by pressing the tracking release key, the communication function between the mobile communication device terminal 5 and the mobile electronic tag 4 is temporarily stopped and the mobile communication device terminal 5 is managed. It is desirable that the communication function with respect to the server is temporarily stopped, so that unnecessary information is not transmitted from the mobile communication device terminal 5 to the management server.

  In addition, when a predetermined time (for example, 24 hours) elapses after the tracking release key is pressed, information is transmitted from the mobile communication device terminal 5 to the management server, and a specific electronic tag reader It is desirable to read only information stored in the mobile electronic tag 4 containing the identification number, so that the occurrence of the incident can be automatically recognized and tracking can be started.

  Other system configurations include a fixed electronic tag reader installed on the fixed object 1, an information network that extracts information from the fixed electronic tag reader, a management server that manages the obtained information, and an identification number. Is recorded, and includes a mobile electronic tag 4 having a reader function for generating electromagnetic waves 6 and a battery, and a terminal electronic tag reader for the mobile communication device terminal 5. When the electronic tag 4 and the mobile communication device terminal 5 have a function of communicating with each other for a certain period of time, and the communication between the mobile communication device terminal 5 and the mobile electronic tag 4 is interrupted, the mobile electronic tag 4 has a battery May be configured to generate the electromagnetic wave 6 and to transmit the identification number to the fixed object 1 electronic tag reader.

  With this configuration, it is possible to obtain information on the mobile electronic tag 4 in real time, and since no useless information is collected, it is possible to collect information without applying a line load.

  In addition, the management server may be configured to have a function of confirming the movement history of the identification number, so that when an incident such as a kidnapping occurs, it can be immediately monitored and tracked on a monitor.

In addition, the communication frequency of the mobile electronic tag 4 in this case may be any frequency, but is preferably 433 MHz to 960 MHz (UHF), and is relatively compared to the IC tag of 13.56 MHz or 2.45 GHz. Increases communication range.
Note that UHF in general communication refers to a frequency band of 300 MHz to 3 GHz, but currently in the IC tag field refers to a 433 MHz band and an 860 MHz to 9690 MHz band.

  Further, the memory unit incorporated in the mobile electronic tag may be constituted by any one of flash memory, ferroelectric memory, or magnetic random access memory (MFRAM), and in particular, ferroelectric memory (FeFRAM). ) Is preferable because it consumes less power and has a high writing / reading speed.

According to the present invention, since the net of the IC tag leaves a history of a moving body such as a child, the gait itself is a risk for the culprit regardless of where it is hidden. It leads to decrease.
Furthermore, even if a child is kidnapped, the child can be traced immediately, so that the investigation can be carried out without hearing the nearby residents, and crime control and early case resolution are possible. Can contribute.

  The present invention carries a fixed IC tag (passive type) installed on a fixed object such as a telephone pole, traffic signal or traffic sign, and a mobile object such as a schoolchild or a human or a pet and records an identification number. A system comprising a mobile phone IC tag (active type) with a reader function that generates electromagnetic waves and a battery, and a terminal IC reader of a mobile communication device terminal such as a mobile terminal represented by a mobile phone. When the mobile IC tag and the mobile communication device terminal have a function of intermittently repeating communication between the mobile IC device and the mobile communication device terminal at a constant time, and the communication between the mobile communication device terminal and the mobile IC tag is interrupted, the mobile IC tag Is used to generate electromagnetic waves by using a battery as a power source, and to transmit an identification number to a fixed IC tag to track the behavior of a moving object.

  The present invention also provides a fixed IC reader installed on a fixed object such as a telephone pole, traffic signal or traffic sign, an information network for extracting information from the fixed IC reader, and a management server for managing the obtained information A mobile IC tag (passive type) that records an identification number to be carried by a mobile body such as a schoolchild or a human or a pet, and a terminal IC reader of a mobile communication device terminal such as a mobile terminal represented by a mobile phone The system is configured such that the mobile communication device terminal has a function of intermittently communicating between the mobile IC tag and the mobile communication device terminal for a certain period of time, and communication between the mobile communication device terminal and the mobile IC tag can be performed. In case of interruption, information is transmitted from the mobile communication device terminal to the management server, and only the information of the mobile IC tag containing a specific identification number is read from the fixed IC reader. It is to track the behavior of the moving object.

Note that the power supplied from the rectifier 21 is used as the operation power source of the personal IC tag 20 in the steps b and c.

In this Example 1, a child abduction is assumed, but in the case of a child abduction case, the gaiter is likely to turn off the power of the mobile phone because the step is understood by the mobile phone, thereby, Although communication between the mobile terminal 30 and the personal IC tag 20 becomes impossible, movement traces are recorded on the fixed IC tag 40 by the operations d to f.
In addition, since the function of the mobile terminal 30 is not used when entering the position tracking stage, the position tracking can be performed even when the mobile terminal 30 goes out of the call area.

Next, the position information tracking system according to the second embodiment of the present invention will be described with reference to FIG. 5. In this case, the basic system, the configuration of each IC tag, and the IC reader are the same as those in the first embodiment. Since this is the same, only the operation flow will be described.

  In the fifth to seventh embodiments, although not particularly mentioned, when communication is resumed after the tracking release key is operated as in the third embodiment, the communication is resumed with the fixed IC reader or the management server. It is also possible to send information to that effect and stop collecting information on personal IC tags with a specific identification number by a fixed IC reader, thereby avoiding sending and collecting useless information. it can.

  In the fifth to seventh embodiments, the information is recorded in the FRAM of the fixed IC reader when information collection by the fixed IC reader exceeds a certain period, as in the fourth embodiment, although not particularly mentioned. Information may be erased, or it may be possible to overwrite the memory cell area in which information that has passed for a certain period of time is recorded, thereby increasing the capacity of the FRAM built in the fixed IC reader. It can be configured with a low-capacity memory such as 64 kbit, which makes it possible to reduce the cost of the fixed IC reader and to construct the position information tracking system at a low cost.

  In each of the above-described embodiments, the rewritable memory unit constituting the memory unit is configured by FRAM in consideration of low power consumption, but is not limited to FRAM, and is not limited to flash memory or MRAM. Other nonvolatile memories such as the above may be used.

  In each of the above embodiments, the communication frequency band of the IC tag or the IC reader is set to the UHF band in consideration of the communicable distance, but is not limited to the UHF band, and 13.56 MHz or 2.45 GHz. It goes without saying that IC tags or IC readers using other frequency bands may be used.

  In each of the above embodiments, a mobile phone is assumed as a mobile terminal. However, the mobile phone is not limited to a mobile phone, and has a performance capable of communicating with a fixed IC reader or a management server by a self-built-in power supply. What is necessary is just to have.

In each of the above embodiments, schoolchildren abduction or child abduction is assumed, but the subject of location information tracking is not limited to schoolchildren or children, but the disappearance of ordinary people including OL It can also be applied to countermeasures and wrinkle monitoring of patients with dementia.
In the case of wrinkle monitoring of a dementia patient, the mobile terminal may be fixed in the living room or home of the dementia patient.

  In addition, the tracking target is not limited to humans, but is also applicable to escape tracking of pet dogs or pets. In this case, a personal IC tag is attached to a pet collar, Take your mobile device with you when you take a walk, press the tracking release key of the mobile device when you are at home, and set the effective period of the tracking release key to 24 hours, etc. Is possible.

Furthermore, the tracking target is not limited to living things, but can also be applied to anti-theft measures for works of art and transported cargo. A mobile terminal may be placed in the vicinity of goods and transported cargo.
However, in this case, it is desirable that the personal IC tag is an active IC tag and that the communicable area is set wide.

  In the first to fourth embodiments and the seventh embodiment, a thin dry battery is assumed as a battery built in an active IC tag. However, the battery is not limited to a dry battery, and a secondary battery such as a storage battery. In this case, in the process of periodically communicating with the mobile terminal, electromagnetic waves are supplied from the mobile terminal for more than the time required for information collection, and the secondary battery is supplied. Power may be supplied sequentially, and when tracking of position information is disclosed, electromagnetic waves are supplied from the fixed IC reader for a time longer than that required for information collection, and power is sequentially supplied to the secondary battery. You may do it.
