In general, an unmanned security system is a platform that sets up a protected area such as a house, office, or a shopping mall, gives access to the protected area, and detects and prevents external intrusion.

This unmanned security system mainly attaches sensors to entrance doors and windows, and determines that an external intrusion has occurred when it detects a forced opening rather than a normal opening of the entrance door, and generates an alarm or notifies a security company or 112.

However, this conventional method not only forms a separate sensing device on the door and the window, but in some cases, separate equipment for communication other than the sensing device occupies a separate space, which is not good in appearance and is not desirable in terms of indoor space utilization. There has been a point. In particular, in the case of windows, it was one of the main problems of not using an unmanned security system because even people living indoors felt a sense of resistance to the sensing device.

The smartphone 600 accesses the intrusion-related information stored in its own memory to the big data server 500 through the home network 300 and transmits the intrusion-related information, so that the actual external intrusion status by the big data server 500 Whether or not it can be analyzed.

More specifically, the big data server 500 determines whether the distance information separated by intrusion-related information is greater than or equal to a preset distance threshold, and whether it is the first external intrusion state through the analysis of the intruder pattern stored in advance through the analysis of the CCTV image. Can be distinguished. That is, the big data server 500 may analyze that distance information has been generated that exceeds a distance threshold at which a person can intrude, and when the distance information is generated, image recognition for a CCTV image may be performed. That is, the big data server 500 is the intruder pattern excluding the background from the CCTV images collected in the external intrusion state through numerous smartphones constituting the smart window alarm system 1 using a multi-purpose alarm device through the home network 300. Information is collected and stored in advance, and by comparing the patterns of objects included in CCTV image information, such as various intruder pattern information, each intruder pattern information is inclined, reversed, and slightly inclined. In the video, it is possible to determine whether it is in an external intrusion state.

Thereafter, the big data server 500 analyzes the on/off control list through the human body detection sensor formed in the indoor/outdoor lighting as intrusion-related information and the on/off control list that is automatically controlled for the indoor/outdoor lighting in the external intrusion state. , In the state where the door lock of the room with the window frame 20 in which the multi-purpose alarm device 100 is installed is automatically turned on, the room with the window frame 20 in which the multi-purpose alarm device 100 is installed is analyzed as an external intrusion condition. Whether there is movement to the room is analyzed through the on/off control list through the human body detection sensor formed in the indoor and outdoor lighting as intrusion-related information, and the temporal sequence of the on/off control list through the analyzed human body detection sensor is the external intrusion state. In the case of being in a lower priority than the on/off control list, which is automatically controlled for indoor and outdoor lighting, it can be analyzed as the final external intrusion state, which is the secondary external intrusion state that destroyed the door lock, which is the primary blocking line.

Meanwhile, the big data server 500 uses the home automation system 200a connected to the in-house AP 200 through the home network 300 for the on/off control list through the human body detection sensor formed in the indoor and outdoor lighting as intrusion-related information. Through the access of, the on/off control list stored on indoor and outdoor lighting, which is an IoT smart device stored on the home automation system 200a, may be collected by itself.

When the smart phone 600 receives information about whether it is an actual external intrusion state received through the big data server 500 (the first external intrusion state, the second external intrusion state), After accessing the data server 500 to request and receive intrusion-related information that determines the primary external intrusion status and the secondary external intrusion status, the smart phone ( 800) terminal identification number as metadata, intrusion-related information and external intrusion status information (primary external intrusion status, secondary external intrusion status) are transmitted and stored, so that they can be used later as evidence. .

In addition, when the smartphone 600 directly receives information on the secondary external intrusion status among information on whether it is an actual external intrusion status, the smart phone 600 is sent to the National Police Agency server (not shown) through the home network 300. By using the terminal identification number of 800 as metadata, intrusion-related information and information about whether an external intrusion status (second external intrusion status) is automatically transmitted, it is possible to improve user convenience.

The present invention can also be implemented as a computer-readable code on a computer-readable recording medium. The computer-readable recording medium includes all types of recording devices that store data that can be read by a computer system.

Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, and optical data storage devices, and are implemented in the form of carrier waves (for example, transmission through the Internet). Includes things.

In addition, the computer-readable recording medium is distributed over a computer system connected through a network, so that computer-readable codes can be stored and executed in a distributed manner. In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers in the technical field to which the present invention belongs.

As described above, in the present specification and drawings, a preferred embodiment of the present invention has been disclosed, and although specific terms are used, this is only used in a general meaning to easily explain the technical content of the present invention and to aid understanding of the invention. , It is not intended to limit the scope of the present invention.
