FIG. 1 is a block diagram illustrating the components of a physical security system combining a UWB positioning technology and a counting technique according to an embodiment of the present invention. FIG. 2 is a block diagram of a UWB positioning system according to an embodiment of the present invention. And a security zone and an entrance of the physical security system in which the technology and the counting technology are integrated.

The physical security system 1 incorporating the UWB positioning technology and the counting technique according to an embodiment of the present invention includes an ILS (Intelligent Location System) tag 10, an ILS tag 10 in a designated area 200, A server 30 connected to a plurality of APs through a network and a server 30 in real-time communication with the plurality of APs 20 and collecting positional information of the AP 30, A mobile device management (MDM) server 50 capable of communicating with the server 30 and the central control unit 70 and a central control unit 70 wirelessly connected to the server 50 can do.

A separate mobile terminal 60 may be included in the security system 1 if the ILS tag 10 is not embedded in the mobile terminal 60 or in the case of an unauthorized traveler not holding the ILS tag 10.

The ILS tag 10 can transmit a signal to the APs 20 and can transmit a beacon signal or the like with a predetermined periodicity by incorporating a UWB (Ultra Wideband) Integrated Circuit (IC). The ILS tag may be embedded in the mobile terminal 60 or may be a separate tag terminal (not shown).

The APs 20 can receive the signal transmitted from the ILS tag 10 in real time and collect the positional information of the ILS tag 10. These APs 20 may be at least three or more depending on the size of the designated area. Each of the APs 20 can be mutually connected by a UDP / IP communication method. The location information of the ILS tag 10 is transmitted from the APs 20 to the server 30 through the module for adjusting the synchronization method for the location information of the ILS tag 10.

The server 30 analyzes and stores the position information of the ILS tag 10 and can calculate position information of the ILS tag 10 based on triangulation. The triangulation technique measures the distance between the ILS tag 10 and the APs 20 by measuring the time of arrival of the radio waves between the ILS tag 10 and the APs 20 and measures the distance.

For example, the AoA (Angle of Arrival) method is a typical method of calculating a position by measuring an angle by calculating a moving object position using a direction angle between a tag and APs. In addition, ToA (Time of Arrival) is an algorithm that measures the position using the arrival time of a signal. It measures the arrival time between the tag and three or more APs to obtain the distance between the tag and AP, To find the contact point of the circle and to calculate the position of the moving object.

TDoA (Time Difference of Arrival) is an algorithm that finds a point where the distance difference between terminals is constant by measuring the arrival time difference between a tag and signals transmitted and received by two or more APs. In addition, RSSI (Received Signal Strength Indicator) is a method of calculating the position of a moving object by using the strength of a signal received from three or more APs. The position of the tag is measured by measuring the degree of attenuation of the signal generated when each AP receives the transmission signal of the tag.

The count sensor 40 is provided in the vicinity of a door that enters and exits the designated area, and counts the number of persons entering and leaving the door through the infrared / 3D image in real time.

In the case of the conventional CCTV or door opening / closing sensor, there is a problem that the CCTV should continuously check the number of the other person directly. In case of the door opening / closing sensor, the tail gating, Can not be prevented. That is, using only the CCTV and door opening / closing sensor can not recognize and detect the unauthorized person's access in real time.

The count sensor 40 can communicate with the server 30 in real time and transmit the counted number of passengers to the server 30. [ The server 30 receives and calculates the position information of the ILS tag 10 from at least one of the APs 20, so that the number of the ILS tags 10 receiving the position information can be known. Then, the server 30 receives the counted number of passengers from the count sensor 40, and can know the number of persons who actually went in and out.

The server 30 can identify the entry / exit of the unauthorized person by comparing the number of the ILS tags 10 with the number of the passengers. The server 30 may inform the central control unit 70 of the number of ILS tags 10 and the number of passengers or may compare the number of the ILS tags 10 with the number of passengers in the server 30 The central control unit 70 may be informed that there is a difference.

That is, the server 30 can compare and determine the number of the ILS tags 10 from which the position information has been collected in the AP 20 and the number of persons who have entered the designated area 200 counted by the count sensor 40 The central control unit 70 connected to the server 30 wirelessly transmits the result of the comparison determination when the number of the compared ILS tags 10 and the number of the entered and exited persons are different.

The server 30 can know the position of the person holding the ILS tag 10 through the positional information of the ILS tag 10 and can recognize the position of the person holding the ILS tag 10 in the designated area 200 It can determine where it is located and is moving. Therefore, when an accident occurs in the designated zone 200, the position and the like of the demanding person can be accurately grasped.

At this time, the actual number of passengers can be grasped by using the counting sensor 40, and when an accident such as a building collapse occurs, the number of accidents in the building can be accurately grasped. That is, the actual number of passengers can be known through the counting sensor 40, and the person who has the ILS tag 10 can know the final position before the collapse of the building.

The MDM (Mobile Device Management) server 50 can communicate with the server 30 and the central control unit 70 and can control the authority of the mobile terminal 60. The MDM server 50 may grant a predetermined first right to the mobile terminal 60 of the authorized accessor and may also grant the preset second right to the mobile terminal 60 of the person entering the secure area 210 .

The central control unit 70 determines whether the ILS tag 10 has entered into the secure zone 210 within the specified zone 200 based on the location information of the ILS tag 10 from the server 30, To the mobile terminal 60 having the ILS tag 10 or the mobile terminal 60 of the person having the ILS tag 10. [

The server 30 also receives the location information of the ILS tag 10 through the APs 20 and when the ILS tag 10 enters the security zone 210 within the designated area 200, To the central control unit 70, the security zone 210 entrance information of the person who owns the security zone 10.

The central control unit 70 determines whether the ILS tag 10 has entered into the secure zone 210 within the specified zone 200 based on the location information of the ILS tag 10 from the server 30, The operation of the program stored in the mobile terminal 60 having the ILS tag 10 built therein or the mobile terminal 60 having the ILS tag 10 can be restricted.

Also, the central control unit 70 may initialize the specific mobile terminal 60 through the MDM server 50 when an initialization request of the specific mobile terminal 60 is input. This is because the central control unit 70 can initialize the lost mobile terminal 60 in the designated area 200 to prevent damage such as leakage of personal information.

The central control unit 70 can grasp the position of the ILS tag 10 and the counting information of the count sensor 40 through the information collected from the server 30 and can integrate the server 30, the MDM server 50, And the collected information can be displayed so that the administrator can grasp the situation in the designated area 200.

The authorization of the mobile terminal 60 may be controlled by the MDM server 50. The policy of the MDM server 50 may be reflected in the mobile terminal 60 depending on the operating system of the mobile terminal 60. [ The existing location-based MDM services such as Wi-fi and Bluetooth are not available for the mobile terminal 60 using Ios due to a policy problem. However, the UWB ILS-based MDM service can be applied to all operating systems that use real time location information shared on the server 30 and transmitted to each mobile terminal 60.

The operation of the MDM server 50 may be performed in the central control unit 70.

The mobile terminal 60 may include various devices such as a notebook, a tablet PC, a PDA, a smart phone, and a mobile phone.
