Description

Child crime prevention system {CRIME PRIVENTION SYSTEM FOR CHILD}

The present invention relates to a child crime prevention system, and more particularly, to a child crime prevention system capable of more active child crime prevention by enabling the positioning and danger warning even when children move on the street.

In general, as society becomes more sophisticated and complicated, more cases of children are subject to crime, and crimes against children such as child abduction, disappearance, and assault are gradually increasing.

In order to protect children from crime, parents have been forced to go to school and to educate their children not to follow strangers, but they have not lowered the crime rate for children.

In order to prevent crimes against children as described above, CCTVs are installed in places where child kidnappings may occur, and mobile phone and GPS terminal location services are used for monitoring.

The CCTV is installed in the area of high risk of kidnapping to monitor the kidnapping of the child, the mobile phone and the GPS terminal is to check the current position of the children through the base station of the mobile carrier when the children carry.

Of course, the location of the children using the mobile phone and the GPS terminal must be subscribed to a separate service, and must also use a model that supports it.

However, as described above, in order to monitor the kidnapping of children by installing CCTV, not only a large number of CCTVs need to be installed, but also a lot of blind spots that cannot be photographed by CCTV, child crime such as kidnapping of children only by installing CCTV. There is a problem that can not be prevented.

In other words, CCTV is often used as evidence for catching criminals when a child crime occurs. Actually, CCTV cannot prevent child crime, and if a criminal wears a hat, it is difficult to identify the criminal. .

In addition, even if parents are informed of the location information of the children through the mobile phone to enable the location tracking, the location tracking through the mobile phone is based on the base station, so the limit of the number of base stations (distance between base stations) Due to the propagation intensity characteristic and the location tracking error is very severe, there is a problem that can not inform parents according to the location tracking information in real time.

In other words, the location tracking by the mobile phone has errors that range from several hundred meters to several kilometers, making the location tracking practically meaningless.

In addition, the location tracking through the GPS terminal is also impossible to track the location in the shadowed area of the GPS, it is difficult to use practically because the price of the GPS terminal is expensive.

Accordingly, an object of the present invention is to solve the above problems, the child crime prevention system that enables the children to track the location at a very low price and there is little error in the location tracking as well as real-time location tracking In providing.

In addition, when the children send a danger signal through the portable terminal along with the location of the children, the danger signal and video are immediately sent to the parents' mobile phone and control center so that they can know the situation and contact the police promptly. It is to provide a child crime prevention system to prevent crime.

In order to achieve the above object, the present invention provides a main server installed in a control center, a portable terminal configured to carry children and to carry out short-range wireless communication, and to store related information such as IDs of children. And a wireless AP configured to perform short-range wireless communication with the portable terminal and having location information stored therein, and connected to the main server through an internet network to transmit children's information and location information to the main server when communicating with the terminal. It is characterized by a modular configuration.

As described above, the present invention is able to inform the location and the situation of the children to the control center and the mobile phone in real time through the portable terminal and the wireless AP module possessed by the children, the location and situation of the children is made more accurately and quickly By doing so, it is possible to prevent crime of children at low cost.

1, 2, and 3 are block diagrams showing a child crime prevention system according to the present invention, and a block diagram showing a system diagram of the system and a text and video transmission path through a mobile communication company, which are installed in a control center. A main terminal, a portable terminal configured to carry with the children and capable of short-range wireless communication and storing related information such as IDs of the children, and a short-range wireless communication with the portable terminal. A wireless AP (ACCESS POINT) module is stored and connected to the main server through an internet network and configured to transmit information of children and location information when communicating with a terminal.

The wireless AP module and the portable terminal are configured to communicate with each other through a ZIGBEE device, which is a short range wireless communication device. When the portable terminal is located within about 50 meters, the terminal automatically performs a short range wireless communication with the wireless AP module. The relevant information and location information of AP are transmitted to main server of control center and displayed on monitor of main server.

In addition, as shown in FIG. 3, the DDNS server (not required for a dedicated line), an SMS server, a mobile server, and an ID authentication server are connected to the main server to transmit text and video through a base station of a mobile communication service provider. In the wireless AP module, when the ID and location information of the child and the related information are transmitted to the main server of the control center, the text message and the image information (for example, Hyunju (name)) related to the present location -The phrase stored in the SMS server is transmitted to the mobile phone of the parent through the base station of the mobile operator.

The parent's mobile phone is connected to the parent's mobile phone number from the student information related to the terminal ID in the database stored in the main server, and authenticated by the ID authentication server.

In particular, in order to view the CCTV video on the mobile phone, the mobile video viewer must be downloaded and installed through the corresponding carrier (or the corresponding mobile phone manufacturer).

That is, in the area where CCTV is already installed, the CCTV and the wireless AP module are configured to transmit and receive image information by interlocking with each other. Since the CCTV and the speaker are installed together, the CCTV video signal and the speaker and microphone are transmitted and received. An A / V IP transmitter is installed to transmit a signal to the main server of the control center through the gateway.

In the area where the CCTV is installed, when the wireless AP module and the terminal that the children carry communicate with each other, the video signal recorded by the CCTV is transmitted to the main server and the mobile phone of the parent in real time so that the location and situation of the children can be known in real time. Will be.

Here, the speaker is output the voice signal transmitted from the control center, the microphone is to transmit the sound in the field to the control center, it is possible to control the site through the speaker to listen to the sound of the field situation in the control center. .

The portable terminal is equipped with an emergency button, and the emergency safety pin is installed at the part connected to the neckband to hang on the neck, so that the emergency button or the child can not press the button when pressing the button When the outsider (criminal) is pulled out, the emergency safety pin is removed and the emergency signal is sent out.

Here, the circuit configuration for transmitting the emergency sound by the emergency button and the emergency safety pin is general and will not be described in detail.

In particular, when the mobile terminal is in a range in which the terminal cannot search for a wireless AP, the other terminal receiving the search signal serves as a node (NODE) to search for the surrounding wireless AP module to control location information and emergency signals. It is configured to transmit to the center and mobile phone.

Referring to Figure 4 illustrates the effect of the present invention as described above when children go to school or walk on the road to the portable terminal that stores the registration information (terminal ID, child name, guardian cell phone contact, school information) Will be possessed.

While carrying the portable terminal described above, it is determined whether the emergency signal is sent from the portable terminal to determine whether it is a general situation (e.g., going to school or walking in general) or an emergency situation. In the state, it is judged as a general situation.

If it is determined that the portable terminal is in a general situation, the wireless AP module that can communicate with the surroundings is searched. If the wireless AP module is located within about 50 meters, the terminal accesses and starts communication.

However, if there is no wireless AP module within the communication range, the portable terminal carried by other children is searched for being within the communication range. If there is another terminal, the terminal accesses the wireless AP module as a communication node.

That is, as shown in FIG. 5, if there is a portable terminal of children within the communication range of the wireless AP module, communication is possible immediately. However, communication is not possible in a state outside of this range. The communication node can be connected to the wireless AP module.

When the mobile terminal of the children is connected to the wireless AP module to communicate, the registration information stored in the terminal is transmitted to the wireless AP module and checked by the ID authentication server, and the SMS server is connected to the main network of the control center through the Internet. The text message is sent to the server and the text message is transmitted to the mobile phone of the parent through the base station of the mobile communication company.

In this case, the wireless AP module and the terminal are in close range communication, and thus the position information of the wireless AP module becomes the position information of the children, so that the position of the children can be determined very accurately.

As shown in FIG. 6, the text message in the form of "Hyunju is passing 00 place on 00 00 0000" is immediately sent to the parent's mobile phone, so that the parents can see the current location and situation of the children in real time. You will know.

Of course, when CCTV is installed in the wireless AP module connected to the terminal, the video signal is transmitted through the A / V IP transmitter and the gateway, and the current video information of the children on the monitor (not shown) of the control center and the mobile phone of the parent. Can be delivered.

As described above, when the child presses the emergency button or the emergency safety pin is released while the real-time information is transmitted to the control center and the mobile phone of the parent, the emergency signal is transmitted from the portable terminal to determine the emergency situation. In addition to searching and accessing modules, emergency signals and location information are transmitted.

Emergency signals and location information sent from the portable terminal is transmitted to the cell phone of the control center and parents, when the CCTV is installed, as shown in Figure 7, video signal with a text message (emergency message) to the control center and mobile phone Can be transmitted to better understand the site situation.

At this time, the control center (school, police, etc.) in the area where there is no CCTV immediately call the nearest police station from the location to the police to safely and quickly rescue the children.

In particular, in the area where CCTV is installed, the microphone and speaker are installed together. In addition, the control center can not only warn people who want to harm the children through the speaker, but also sends out alarm signals so To help them.

As described above, the wireless AP module that can be configured very inexpensively and the portable terminal possessed by the children communicate with the control center and the mobile phone through the Internet in real time while providing short-range communication. Without the need to be able to locate children very accurately, they can help children quickly in an emergency.
