The control unit 110 may perform overall control for performing the anti-theft function.

That is, the security mode registration of the RF reader unit 120 is set to be possible, and the vibration signal from the detection unit 130 is provided to determine whether theft is detected, and the location is tracked by GPS or not to the outside. To this end, the controller 110 may be a programmable microcontroller unit (MCU) such as a Raspberry Pi or an Arduino.

The RF reader unit 120 initially registers a security card (not shown) to which an RF tag is attached and exists separately from the anti-theft device, and reads the security card through RF communication within a recognition distance to operate the security mode, Theft can be prevented by re-reading the card and canceling the security mode.

The detection unit 130 provides the control unit 110 with a vibration signal that senses vibration due to movement in case of theft to determine whether the theft has occurred.

The wireless communication unit 140 has a built-in short-range wireless communication protocol, and may provide an alarm signal to the portable terminal by interworking with a portable terminal (not shown) located in a short distance according to the setting of the control unit 110 . The short-range wireless communication may be, for example, Bluetooth, NFC, RF, ZIGBEE, Z-WAVE, or the like.

An open structure is formed to facilitate communication with and effectively dissipate internal heat.

In addition, the protrusion 12 is manufactured to protrude so that cable wiring of various configurations is easily connected, and the inside is penetrated, so that the antenna of the wireless communication unit 140 or the GPS unit 160 is inserted to facilitate communication with the outside. can also be performed.

In addition, the case 10 may include a mounting bracket or a Velcro-type tape for attachment to be used as an attachment type on the side or back side.

Furthermore, the control unit 110 of the present invention enables the RF reader unit 120 and the vibration detection sensor and the acceleration sensor included in the detection unit 130 to interlock to determine whether theft is stolen, specifically, the RF reader unit 120 ) is to determine whether or not theft is finally determined by determining whether the vibration signal of the vibration sensor is received above a threshold value in a state in which the set security mode of ) is activated.

In particular, the control unit 110 can be set so that the vibration can be determined as theft when the vibration signal is greater than or equal to a certain threshold value, and is not determined as theft when the vibration signal is less than or equal to the threshold value. It may be affected by wind, etc.

Furthermore, since the control unit 110 can measure the acceleration value of the anti-theft device 100 using the acceleration sensor, it generates pattern information using the displacement of the acceleration value, and the artificial intelligence programmed inside the control unit 110 . By applying an intelligent algorithm, various situations may be recognized and the state of the anti-theft device 100 may be determined according to a pattern.

For example, by using the Support Vector Machine (SVM) algorithm, pattern information can be generated according to the displacement of the acceleration value, and the pattern can be classified using the characteristics and acceleration values of the neural network as parameters. In this way, it is possible to determine the influence of wind on the anti-theft device 100, the inclination of the device, the degree of external impact, and the like for a situation in which the pattern is similar. The pattern determined in this way may be considered when setting the threshold value of the vibration signal, and a value corresponding to the threshold value or less may not be determined as a stolen state.

In particular, if the value is set to a value that is less than or equal to the threshold, in the case of simple movement, if a weak vibration continues for a set time, it may be set below the threshold to be determined as simple movement rather than theft.

In addition, here, the support vector machine is one of the supervised learning machine learning methods mainly used for classification, regression, outliers detection, etc., for data having multiple dimensions. , is a machine learning model used for pattern recognition or data analysis as an optimized method for finding the optimal decision boundary that can distinguish multiple dimensions well.

In addition, as an artificial intelligence algorithm to replace the support vector machine described above, a deep neural network (DNN) may be used, or various artificial intelligence algorithms such as a convolutional neural network (CNN) or a recurrent neural network (RNN) method may be used.
