FIG. 2 is an exemplary diagram for explaining a concept of a vulnerable area crime prevention system by SmartWatch interlocking according to an embodiment of the present invention.

As shown in FIG. 2, a vulnerable area crime prevention system by a smart watch interworking system is constructed such that a street light 200 installed in a crime and a vulnerable area linked with a user's smart watch 100 broadcasts information of a corresponding area , Warning the user of the information of the vulnerable area or the dangerous environment in the vicinity or the moving route in advance to the user so that the user can be prepared or avoided and if an emergency situation such as a crime situation or an accident situation occurs to the user, (200) captures the situation of the user with the installed CCTV as soon as it receives the emergency occurrence signal and sends it to the control center (400) via the wired / wireless communication network so that the police or the guardian can know . In addition, the CCTV, the warning light, the communication equipment, the siren, etc. installed in the streetlight 200 alone can cause the deterioration of the criminal motivation due to the high display effect, and when the crime occurs, the siren, And to increase the brightness of the lighting so as to prevent the criminal from proceeding with the crime. In addition, the smartwatch 100 notifies the emergency through a simple signal to other nearby smartwatches so that the user can receive help from the nearby smartwatch wearer.

In the vulnerable area crime prevention system by the SmartWatch interlocking, the wireless communication method between the streetlight 200 and the smartwatch 100 includes a short-range wireless method, a long-distance wireless method, or a combination thereof. For example, the short-range wireless communication method includes at least Bluetooth, a Zigbee communication with low power consumption and a low cost, or an ISA100, a WirelessHART, an NFC or an infrared communication method which is a security of a Zigbee communication, The remote wireless communication method may include a mobile communication method such as 3G, 4G (LTE), WiFi, or WiBro, or a wireless Internet communication method. It is also possible to use. For reference, the ZigBee is a standard (IEEE 802.15.4, Zigbee) communication method capable of transmitting data at a rate of 250 Kbps in a frequency band of 2.4 GHz to 2.5 GHz (ISM Band).

In the vulnerable area crime prevention system by the SmartWatch interlocking, the control center 400 includes at least one server connected to the streetlight 200 or the AP or the base station 300 through a wired / wireless communication network, And a database storing information including the IDs of the users of the watch 100, the contact information of the guardians, etc., so that the operator or the guardians can confirm the current position and status of the users through the web page in real time Or provides an application so that the status information of the users can be checked at any time by the mobile smart device.

For reference, the streetlight 200 referred to in the present invention is an example of a peripheral installation in a vulnerable area in which CCTV, a warning light, a communication device, a siren, and the like are interlocked with the SmartWatch, In fact, any nearby installation installed in a vulnerable area can be used as a substitute for the streetlight 200. Also, the streetlight 200 may have an access point (AP) in itself, or may form a network with a base station or an AP installed separately thereon with one or more nodes, and the streetlight 200-1 , 200-2, and 200-3 may be wired or may be connected through ad-hoc mode of a wireless LAN such as WiFi. In addition, the CCTV camera installed in the streetlight 200 includes a zooming function, a zooming function, a zooming function, and a pan / tilt function in which the camera follows the subject horizontally or vertically. And a camera assembly having an electric motor mounted thereon so as to be rotatable.

In addition, the streetlight 200 has a dimming control function that illuminates when the user wearing the smart watch approaches, even though the streetlight is in a dark state at night. Even if the user does not perform any operation, So that the user can be aware of the access and the lighting can be gradually increased. This is especially the case when the school is installed in an area where school violence is anticipated. When a student wearing a smart watch approaches a dark place, the nearby street light is suddenly brightened, and the dark lighting is made stronger There is an effect that school violence can be prevented.

In addition, each constituent means constituting the streetlight 200 is merely illustrative, and may be substantially equipped with various means and safety devices as well as the constituent means, The configuration of each streetlight may be different depending on the environment of the vehicle.

FIG. 3 is a flow chart for explaining the operation of a vulnerable area crime prevention system by a smart watch interlock for informing a user in advance of a crime and a vulnerable area according to an embodiment of the present invention. As shown in FIG. 3, 200 receives the information of the crime and the vulnerable area from the control center 400 (S101) and broadcasts it around (S103). At this time, the smartwatch 100 of the user is periodically sensed (S102). When the smartwatch 100 enters the range of broadcasting the crime and vulnerable information of the streetlight 200, the smartwatch 100 of the user transmits the broadcast signal Transmits the wearer ID to the street lamp 200, and the street lamp transmits the situation of the user entering the crime and vulnerable area to the control center 400 together with the wearer ID (S104). When the user receives the broadcasting signal of the streetlight 200, the smartwatch 100 notifies the user of the fact that the user has entered the area where the user is vulnerable to the crime and the danger through the alarm operation (S105) If the user goes out (S106), the user is informed that he / she is out of the crime and vulnerable area through the alarm (S107).

FIG. 4 is a flowchart for explaining the operation of the vulnerable area crime prevention system by the smart watch interworking in the occurrence of a crime and a dangerous situation according to an embodiment of the present invention. As shown in FIG. 4, If an emergency is detected in the vulnerable area (S201), an emergency signal is transmitted to the streetlight 200 (S202). The streetlight receiving the emergency signal immediately captures the user's situation by the CCTV and transmits it to the control center 400 and operates the warning light and siren installed to notify the surrounding people of the emergency situation and in case of a criminal situation, (S203). The control center 400 informs the guardian 119, the police, and the like of the user's situation so that it can cope with the situation as quickly as possible (S204). When the emergency situation is over, the smart sensor automatically senses the sensation (S205), and transmits a signal to the streetlight 200 that the emergency situation has ended (S206). The streetlight stops the operation of the warning light and the siren, And transmits the emergency end status information to the center 400 (S207). In addition, the control center 400 having received the emergency situation information immediately informs the guardian of the emergency situation (S208). If an emergency occurs in a situation where there is no peripheral installation to be interlocked with the SmartWatch, the SmartWatch 100 interworks with the user's smartphone through the Bluetooth to control the emergency information, To the center 400. In addition, the streetlight 200 is not limited to a streetlight, but may be replaced with a crime prevention device, a CCTV camera, a node including a separate network function, and various terminals held by a neighbor or a user. In particular, a terminal of a specific user can communicate with the smartwatch 100 while exchanging information with the control center 400, such as the streetlight 200, as a mobile streetlight. As such, the streetlight is a concept including a moving streetlight, a moving CCTV camera, a mobile crime prevention device, a node device having a mobile network means, or a combination thereof.

The method of automatically determining the emergency state of the smartwatch 100 by the smartwatch 100 is a method in which, for example, when a pulse of a user suddenly increases more rapidly than usual or falls sharply than usual Or if the user's pulse is increasing more rapidly than usual (ie, if it can be predicted to run away from something), the current state of the user It is determined that the emergency is in an emergency state and the emergency call can be automatically performed. A method for automatically determining the emergency state is described as an example and a method for determining more emergency states (i.e., combinations of information detected through the sensor unit) is predefined in the form of a database or a look-up table It can be stored in the SmartWatch storage unit.

FIG. 5 is a flowchart for explaining a CCTV connection protocol of a vulnerable area crime prevention system by SmartWatch interworking according to an embodiment of the present invention. As shown in FIG. 5, in the vulnerable area crime prevention system by the SmartWatch interworking The streetlights 200-1, 200-2, and 200-3 formed with the wired / wireless network may be configured such that the location of the user is moved due to a criminal or a circumstance in a criminal situation or a dangerous situation, or after the emergency signal is transmitted, It is possible to collaborate effectively so that the situation of the user can be photographed even in the peeling state. In the CCTV camera collaboration protocol of the streetlight for the photographing linkage, the streetlight 1 receives the SmartWatch 100 signal of the user and starts shooting (S301). Then, the direction of movement of the user location and the state information To the street lamp 2 and the streetlight 3 having the network formed therein (S302). At this time, the streetlight 2 and the streetlight 3 change their state information to a state preparing for photographing, and rotate the CCTV camera in the direction of the user based on the moving direction of the user location transmitted from the streetlight 1 and the location information of the streetlight 1 S303). The streetlight 1 changes the CCTV camera to the standby state when the user is out of the shooting range of his / her own, and transmits the current state of the streetlight 2 to the streetlight 2 and the streetlight 3 in step S304. The street light 2 and the street light 3 are continuously prepared to detect the user, and the street light 2 detects the monitored object again and starts monitoring (S306). At this time, the streetlight 2 changes its own state information to the monitoring state in which the photographing is started, and transmits the state information to the streetlight 1 and the streetlight 3 formed with the network. Even if the user hits an emergency situation through the network between the streetlights as described above, it is possible to secure the safety of the user by shooting the situation information to the end.

According to another embodiment of the present invention, there is provided a method for controlling at least one or more nodes including at least one smartwatch, a streetlight, a warning light, a crime prevention device, a CCTV camera, A vulnerable local crime prevention system with SmartWatch interworking comprising at least one node and a control center connected to a wired or wireless communication network is used to eliminate blind spots between the SmartWatch, nodes, control centers or combinations thereof, To increase the reach distance, the network can be configured using a non-RF LF (Low Frequency) transceiver.

The LF transceiver is used for mobile communication and ship broadcasting. Providing location-based services using LF can prevent blind spots by using zigbee or the like. In addition, since the communication distance is also long when the LF transceiver is used, the communication characteristic can be stably communicated even when there are obstacles (people, objects, etc.) in entering and exiting the vulnerable area.

The LF has a frequency range of 30 to 300 kHz and a wavelength of 1 to 10 km. The distinction by wavelength is kilometric wave and is often called long wave. The frequency of the LF band has been widely used for long distance communication between vessels, but it is currently used mainly in the radionavigation service such as Decca, Loran C, beacon for ships and aircraft. Accordingly, it is possible to increase the wireless reach distance to eliminate blind spots, and to reduce the blocking of wireless signals from obstacles, thereby further enhancing the utility of the vulnerable area crime prevention system by the SmartWatch interlocking method of the present invention.
