Recently, violent crimes against socially underprivileged such as children, adolescents, women and the elderly are frequently occurring. In these circumstances, the impact of child and youth sexual crimes and school violence has reached a critical level, with countermeasures that allow police to directly track the location of the complainant.

Many security products for personal safety have been released.

Various products have been introduced, including self-protecting devices that protect the body from the offender, and alarms that alert people around the subway and emergency situations when they are robbed or molested in the subway.

However, most of these products use a communication terminal, which causes inconvenience to users, such as having to wear a device having a considerable weight and volume in the form of a necklace. In addition, these products are exposed to the outside world, so there is a risk that the perpetrator can see the device visibly. In addition, there is a limit that it is insufficient to inform the user of more detailed emergency situation by generating only the location information and alarm of the device itself.

Moreover, if the device is deviated from the victim, the situation information transmission of the victim is terminated at that point, and there is a problem that active risk intervention is difficult. In addition, since the individual communication terminal must be gradientd separately, there is a burden of initial purchase cost and maintenance cost due to the equipment purchase cost and the communication fee. In addition, there is a problem in that the infrastructure construction cost is high because the receiving facilities must be installed in the hazardous area.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are assigned to the same components as much as possible, even if shown on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, the following will describe a preferred embodiment of the present invention, but the technical idea of the present invention is not limited thereto and may be variously modified and modified by those skilled in the art.

1 is an overall configuration diagram of a personal risk recognition and notification system using a smart device according to an embodiment of the present invention. 2 is a detailed configuration diagram of the smart device of FIG. 3 is a case application for preventing and protecting the departure between the smart device holder and the tag reader, Figure 4 is a case application for the protection of the smart device holder.

Personal risk recognition and notification system using a smart device according to a preferred embodiment of the present invention, referring to Figures 1 and 2, comprises an RFID tag 100 and a smart device 200.

At least one RFID tag 100 is attached to a human body or clothing.

As shown in FIG. 3, the

RFID tags

110, 120, and 130 are smart device holders (corresponding to reference numeral 130), and protected persons who do not have a smart device in order to prevent departure and protection between the smart device holder and the tag attacher. (Single or plural) (corresponding to reference numerals 110 and 120) respectively.

In the case of protecting the smart device holder as shown in FIG. 4, a plurality of

RFID tags

110, 120, and 130 are attached to a human body, shoes, and clothing of a person who is not carrying the smart device.

Smart device 200 has a built-in RFID reader (reader), it is possible to detect the RFID tag (100). In this case, the RFID reader may be separately installed in the smart device or installed by mounting a USIM chip including the RFID reader function on the smart device.

The smart device 200 includes a tablet PC, PDA (Personal Digital Assistant), notebook, cellular phone, PCS (Personal Communication Service) phone, Hand-Held PC (GSM), Global System for Mobile (GSM) phone, W- Wideband CDMA (CDMA) phones, CDMA-2000 phones and smartphones, and car terminals can be used. Applications that provide modules related to personal risk recognition and notification functions can be downloaded or used to run embedded applications.

2, the smart device 200 includes a distance setting module 210, a distance recognition module 220, a power maintenance module 230, an alarm sound generating module 240, a camera photographing module 250, and lighting. Module 260, app force termination module 270, text conversion module 280, voice conversion module 290, transmission module 300, and location tracking module 310.

The distance setting module 210 sets a limit distance between the RFID tag 100 and the RFID reader. For example, the distance setting module 210 may set the limit distance between the smart device 200 having the RFID reader embedded therein and the RFID tag 100 to be 5 m. In this case, when the distance between the smart device 200 and the RFID tag 100 exceeds 5m, it is determined that the distance setting module 210 is out of the limit distance and recognized as a dangerous situation.

The distance recognizing module 220 checks a communication situation between the RFID tag 100 and the RFID reader and determines in real time whether the RFID tag 100 recognizes within a limited distance set by the distance setting module 210. On the other hand, the RFID tag 100 checks the operation of the RFID tag 100 even within the set limit distance and recognizes it as a dangerous situation when it is inoperable, as well as departs from the set limit distance and detects the RFID tag from a point recognized as a dangerous situation. Process data up to an unrecognizable point that becomes impossible.

For example, when the RFID tag having a recognition available distance of 10 m is used and the distance setting module sets the limit distance to 5 m, the distance setting module determines that the limit distance is out of the limit distance when the distance between the smart device and the RFID tag exceeds 5 m. And perceived as a dangerous situation. Meanwhile, even if the RFID tag is inoperable even within the set limiting distance of 5m, the RFID tag is not only recognized as a dangerous situation, but also beyond the set limiting distance, the RFID reader can no longer detect the RFID tag from a point exceeding 5m recognized as a dangerous situation. Predict risk situations by processing real-time data up to a distance of more than 10 meters, an unrecognized point.

When the distance setting module 210 sets the limit distance to 5m, when the distance between the smart device 200 and the RFID tag 100 exceeds 5m, the distance recognition module 220 determines that the limit distance has been departed and is dangerous It is perceived as a situation.

The power force maintenance module 230 forcibly maintains the power of the smart device 200 when the distance recognition module 220 recognizes the dangerous situation. When a dangerous situation occurs, the smart device 200 must be maintained for a long time as far as possible from the danger. The power force maintenance module 230 serves to prevent the power of the smart device 200 from being artificially turned off by the movement of the victim or the forced termination of the abuser.

The alarm sound generating module 240 generates an alarm sound when the distance recognition module 220 recognizes that the distance from the limited distance is outside, so that the neighbors and the guardian can quickly recognize the danger situation of the victim.

When the alarm sound is generated by the alarm sound generation module 240, the camera photographing module 250 automatically drives a camera mounted on the smart device 200 to capture a dangerous situation in real time. In a dangerous situation, not only does the victim have no time to drive the camera function of the smart device, but if the victim takes a shooting operation, the abuser will block it, so the camera shooting module 250 automatically drives the camera in a dangerous situation. To shoot the scene.

When the alarm sound is generated by the alarm sound generating module 240, the lighting module 260 illuminates the SOS signal so that a neighbor or guardian can quickly recognize a dangerous situation of the victim. Since sex crimes occur mainly at night, when the surroundings are dark and the identification of the dangerous situation of the victim is difficult, the lighting module 260 has a great effect.

App force termination module 270 forcibly terminates all applications running on the smart device 200, if the distance recognition module 220 recognizes that it is out of the limit distance. When the distance recognition module 220 recognizes that it is out of the limit distance, it faces a dangerous situation. Therefore, it is preferable to shut down all other applications currently being executed so that only the risk recognition and the notification can be focused and prevent power waste.

The text conversion module 280 converts and stores real-time data including a time, a place, a personal image, an expected situation, and a movement trajectory after the application is terminated by the app compulsory termination module 270 into a text. The expected situation can be estimated by the distance change amount and distance change speed and direction between the RFID tags or the distance change rate and distance change speed and direction between the RFID tags and the RFID reader.

The voice conversion module 290 converts and stores real-time data including a time, a place, a personal image, an expected situation, and a movement trajectory into a voice.

The transmission module 300 automatically sends the real-time data converted and stored by the text conversion module 280 and the voice conversion module 290 in the form of text and voice to a predetermined destination. In addition, the transmission module 300 may perform an emergency call automatic call function.

The location tracking module 310 tracks the location of the current smart device 200 in real time using a GPS, etc. built in the smart device 200, so that the location and movement trajectory of the victim can be determined.

Referring to FIG. 3, when the limit distance between the smart device 200 and the RFID tags 110 and 120 is set to 5 m through the distance setting module 210, the distance recognition module 220 deviates from the limit distance. If it is recognized as a strong alarm sound is generated, the real-time position and the elapsed trajectory of the RFID tag (110, 120) is displayed on the screen of the smart device 200.

Through this, parents with infants or children attach

RFID tags

110 and 120 to the human body or clothes of the infants or children, the distance setting module 210 and the distance recognition module 220 of the smart device 200, and various functions. Using modules 230 to 310 to prevent the occurrence of missing children in advance, and when the infant or child is in danger to immediately recognize and respond to the dangerous situation.

On the other hand, since the RFID tag 130 is attached to the human body or clothing of the smart device 200 holder, when the smart device 200 is lost or robbed, it is recognized as a dangerous situation and can cope with it.

Referring to FIG. 4, the smart device 200 recognizes an emergency as an individual body emergencies when deviating from the multiple distance condition between RFID tags and monitors the emergency. Quick location information is sent from the location where the accident occurred, and when the distance between tags, smart devices and tags is removed, real-time location and progress trajectories are collected and sent to related organizations and families within the available distance. It can be inferred and the crime can be prevented by the speedy processing before crime.

In detail, the RFID tags 110, 120, and 130 may be attached to a pair of shoes and clothes of the owner of the smart device 200 to form a triangle as a whole. In this case, the distance setting module 210 of the smart device 200 sets a relative distance between three tags within a specific range, and the distance recognition module 220 of the smart device 200 has a distance between three tags within a limited distance. If the length of any one of the three sides of the triangle is out of the limit distance, it can be recognized as an emergency of the individual body and can respond to it.

This is based on the fact that shoes or underwear are often peeled off when an accident such as a sex crime occurs.

In the event of an accident, such as a sex offense, the offender may forcibly remove the shoe or underwear and leave the shoe or underwear away from the body.

For example, by attaching an RFID tag to a cubic constituting a ring or necklace worn by a victim, if the victim removes a component (such as a cubic), such as a ring or necklace, that he or she wears when in danger, The RFID tag included in the component can also be configured to deviate from the limited distance so that the victim can be alerted to the danger.

The first to third RFID tags 110, 120, and 130 attached to both shoes (corresponding to reference numerals 110 and 120) and clothes (corresponding to reference numeral 130) of the holder of the smart device 200. Recognizing the relative distance between the two and three RFID tags, if the length of each side of the triangle deviates from the preset limit distance, it is determined as an individual body emergency situation.

Accordingly, the power force maintenance module 230 forcibly maintains the power of the smart device 200, the alarm sound generating module 240 generates an alarm sound, the camera photographing module 250 drives the camera, The lighting module 260 lights up the SOS signal. In addition, the location tracking module 310 tracks the location of the smart device 200 in real time, so that the text conversion module 280 and the voice conversion module 290 convert the current location and time into text and voice, and store and transmit the same. The module 300 automatically sends a text and a voice to a preset destination. Although not shown, a screen lock module may be further provided so that the attacker or the victim may not artificially or accidentally stop the operation of the modules by a touch or the like.

5 is a flowchart of an application situation mode of the personal risk recognition and notification method using a smart device according to an embodiment of the present invention. 6 is a flow chart of the application emergency mode of the personal risk recognition and notification method using a smart device according to an embodiment of the present invention.

The application context mode is a process of setting a limit distance between tags or a tag and a smart device, and recognizing when the limit distance is deviated and switching to the emergency mode.

Application emergency mode is a process to perform a variety of notification functions in response to the premise that the dangerous situation.

Referring to FIG. 5, it is checked whether a signal of tag 1 is detected in the application context mode, and if it is not detected, recognizes a dangerous situation and switches to the application emergency mode. If it is detected, once data processing is performed, it is again checked whether Tag 1 is within the set distance. If it is determined that the set distance is out of range, it is recognized as a dangerous situation and the application is switched to the emergency mode. If it is recognized that it is within the set distance, data processing is performed.

On the other hand, after the signal of tag 1 is detected and data processing is performed, it is checked whether the signal of tag 2 is detected, and the above process is repeated.

Referring to FIG. 6, when the application is switched to the emergency mode, power is forcibly maintained and an alarm sound is generated, and the camera photographing and the flash SOS signal are turned on. After all applications are forcibly terminated, elapsed, current, and real-time data are converted to text and stored, and multiple text transmission is performed to the set destination.

In addition, the collected data is converted into voice and stored, an emergency call is automatically sent, and the converted voice is sequentially transmitted. At this time, the transmission content may include an emergency notification, personal information, location tracking agreement, current status notification (location, time), call maintenance, real-time status notification (expected situation, movement trajectory).

When generalizing this, the personal risk recognition and notification method using a smart device according to a preferred embodiment of the present invention is the first of the plurality of RFID tags attached to the human body or clothing of the RFID reader embedded in the smart device holder or tag reader n First step of determining whether a signal of the RFID tag is detected, if the signal of the n-th RFID tag is not detected, the power forced maintenance module forcibly maintains the power of the smart device, and the alarm sound generating module generates an alarm sound The second step in which the camera photographing module drives the camera and the lighting module illuminates the SOS signal, when the signal of the n-th RFID tag is detected, the distance recognition module sets a distance between the smart device and the n-th RFID. The third step of determining whether or not it is within the real time, and if it is determined that it is out of the limit distance, The forced maintenance module forcibly maintains the power of the smart device, the alarm sound generating module generates an alarm sound, the camera photographing module drives the camera, and the lighting module lights up the SOS signal. In this case, n corresponds to a finite natural number such as 1, 2, 3,...

In addition, in the personal risk recognition and notification method using a smart device according to a preferred embodiment of the present invention, the distance recognition module 220 is attached to both shoes and clothes of the smart device 200 when the smart device holder protection Recognizing the relative distance between the first to third RFID tags (110, 120, 130), when the length of each side of the triangle formed by the three RFID tags deviates from the preset limit distance, it is determined as an individual body emergency situation, and maintains power The module 230 forcibly maintains the power of the smart device 200, the alarm sound generating module 240 generates an alarm sound, the camera photographing module 250 drives the camera, and the lighting module 260 The SOS signal illuminates, and the location tracking module 310 tracks the location of the smart device 200 in real time so that the text conversion module 280 and the voice conversion module 290 change the current location and time into text and voice.
