Each example shows a camera and a lighting unit installed on the outdoor side of the front door.

Referring to FIG. 2, the intrusion prevention system of the present invention is configured to monitor in real time an outsider trespassing through a front door, and receives measurement data from a door strike device installed on a frame of the front door and the door strike device to obtain indoor and outdoor devices. It may include a station that controls them.

At this time, in order to access the detailed control of the station, it may be configured to access from an outdoor user terminal through a separate security procedure.

The door strike device of the present invention is directly coupled onto the frame of the front door. A door lock is installed on the front door, and the door strike device is installed on a frame adjacent to the door lock.

When the front door is closed, the door lock and the door strike device are arranged in parallel, and the front door is locked as the engaging part of the door lock enters the door strike device. When trying to open the front door, the front door can be opened by first operating the door lock and withdrawing the hooking part inside the door strike device to the inside of the door lock.

Here, the present invention may further include a lighting unit and a camera disposed on the outdoor side of the front door.

Referring to FIG. 3, each configuration will be described in more detail as follows.

As shown in FIG. 3 , the door strike device may include a sensor unit, an operation switch, a battery, a sound generator, an MCU (processor), and a communication module (first communication module). At this time, the sensor unit may detect any one or more of an external impact, an impact vector, and an impact pattern, a transducer for converting an external physical impact into an electrical signal may be incorporated, and may further include any one or more of an acceleration sensor and a gyro sensor. can In addition, an electrical signal sensed by the sensor unit may be transferred to the MCU.

Here, the operation switch may be operated in an ON/OFF mode or three or more modes, and may include a constant warning mode, an intelligent warning mode, and OFF.

At this time, in the constant warning mode, when the electrical signal generated by the sensor unit reaches the MCU, the MCU can determine whether the detected shock amount is greater than the preset reference shock amount, and if the detected shock amount is greater than the preset reference shock amount A warning sound may be transmitted from the sound generating unit. Accordingly, when an external impact of a certain level or higher is applied, the door strike device may be configured to immediately inform the outside.

Subsequently, in the case of the intelligent warning mode, the detection signal reaching the MCU is transmitted to the station through the communication module, and the station where the learning model is built is configured to distinguish living noise from intrusion noise through more detailed control. can And if it is determined that the external impact on the station is an intrusion by an outsider, a control signal is transmitted to the sound generator of the door strike device so that a warning sound can be transmitted to the outside, and a warning sound is output through a speaker of the warning unit, and a display of the warning unit A warning message may be output through and irradiation of light through a lighting unit of the warning unit.

In the OFF mode, the sound generating unit is controlled not to operate even when an external impact is detected by the sensor unit. At this time, the MCU can transmit data to the station only when an impact greater than a reference impact is generated. In addition, the station may store the received information in a separate storage device or analyze the information and provide a result to the user terminal.

The station may include a plurality of communication modules including a first communication module and a second communication module, a processor including an impact analysis module, an object analysis module, and a main control unit, and a storage device. At this time, the door strike device and the station may be connected to each other through a first communication module system. The station may be connected to the above-described warning unit including the lighting unit and the camera through a second communication module, and the user terminal may be connected through a separate third communication module. In addition, the first communication module is configured through a wired connection or 1:1 wireless communication to prevent others from arbitrarily changing or transmitting data sensed by the moonstrike device in advance. In addition, the camera may be connected to a wired network and the warning unit may be connected with other IoT devices through a LoRa network.

When the impact signal measured by the sensor unit of the door strike device reaches the station through the first communication module, the impact analysis module of the station determines the strength of impact, the duration of impact, and the pattern of impact appearing in the impact signal. and feature vectors can be extracted from the measurement signals measured by the acceleration sensor and the gyro sensor. The main control unit may determine the type of the shock signal by matching the analyzed shock signal with data pre-stored in the storage device or comparing the analyzed shock signal with a reference value.

Referring to FIG. 4 , the main control unit may receive an image of the outdoor side of the front door from the camera through the second communication module when an impact signal is received from the first communication module. The object analysis module of the station may analyze the image of the captured image received by the second communication module and compare before and after the impact signal is sensed by the door strike device. At this time, before the shock signal is sensed, the previously input image may be input in advance as a default, and the image may be received from the camera for each time period, updated, and stored in the memory device. Further, the main control unit may determine whether or not to perform a crime prevention function to the outside according to the impact pattern of the impact signal analyzed by the impact analysis module and whether a new object analyzed by the object analysis module is generated. Here, the crime prevention function may include transmitting a warning sound through a door strike device, outputting a warning voice through a speaker of the warning unit, outputting a warning message through a display of the warning unit, and irradiating light through a lighting unit of the warning unit.

Referring to FIG. 5 , first, the operation switch of the door strike device is operated so that data measured by the sensor unit can reach the station through the first communication module. Accordingly, in the intrusion prevention system of the present invention, real-time monitoring of an external impact may be performed using the door strike device and the station.

Thereafter, the MCU of the door strike device may perform analysis on its own, or the impact analysis module may analyze the impact signal reaching the station to determine whether an impact exceeding a limit level is sensed. In addition, when an impact higher than the limit level is not detected, a real-time monitoring mode may be entered, and when an impact higher than the limit level is detected, the station may receive an image from the camera through the second communication module.

Subsequently, the object analysis module of the station may compare a new image transmitted from the camera with a default image before an impact is detected. At this time, if a new object is not detected in the new image, the main controller of the station may search whether data matching the received shock pattern among the shock patterns pre-stored in the memory device is stored.

Here, the main control unit, when there is information similar to the shock pattern among the pre-stored data, binds the existing shock pattern data and the new shock pattern data as related data, classifies them as life noise, and stores the previously stored data in the memory device. If there is no information similar to the impact pattern, the impact pattern may be classified as a new impact pattern and stored in the memory device. At this time, the new impact pattern is classified as an impact pattern that requires careful attention even though there is no new object detected on the camera at the moment. It can be classified as the living noise and redefined as a safe shock pattern.

In addition, when a new object is detected by the object analysis module, a crime prevention function may be performed. At this time, the crime prevention function may include, as described above, transmission of a warning sound through a door strike device, output of a warning voice through a speaker of the warning unit, output of a warning phrase through a display of the warning unit, and irradiation of light through a lighting unit of the warning unit. .
