Description

Entrance Control System {Entrance Control System}

The present invention relates to an access control system, and more particularly, to an access control system capable of enhancing the security of access to and exits from and to a user.

The non-contact type identification card system comprises an ID card for transmitting identification information or the like as a radio signal in a high frequency form, and an identification device for receiving a signal transmitted from the ID card to confirm the identity of the user.

The non-contact type identification card system using RFID is widely adopted because it is convenient for the user to identify the user even though the user does not have to take out the ID card directly but stores it in his pocket.

In recent years, unmanned control systems have been installed in apartment houses such as apartment buildings, as well as places where security is required, including research institutes and institutes, so that they can not enter without an ID card for identification.

An access control apparatus using a general contactless identification card system includes an RFID reader for receiving RF data, which is user identification information wirelessly transmitted from an ID card, and RF data input from an RFID reader, A central processing unit, and an electric door lock that locks or opens the door under the control of the central processing unit under the control of a door lock control unit for controlling locking or opening of doors of the electric door lock.

According to the above configuration, the access management device receives and analyzes the RF data transmitted from the ID card to determine whether or not the passenger is allowed to enter and leave the door by controlling the electric door lock if the passenger is an authorized passenger.

However, the conventional access control apparatus has a problem that access is allowed even if only the ID card is used. Of course, in general, a camera is installed in the access control device so that the entrance / exit of a passenger can be allowed by photographing the face of a passenger, but a general camera is simply used as a surveillance camera, and its monitoring has been limited.

In addition, there is a need to control access to confidential documents or confidential articles in the company, and security problems are urgently required on a system in which only an ID card is allowed to be accessed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an overall block diagram of an access control system according to the present invention; FIG.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of an access control system according to the present invention will be described with reference to the accompanying drawings.

1, the present invention mainly includes a plurality of access controllers (not shown), a visitor RFID card 11, an article RFID tag 12, a detection sensor 20, a security camera 10, a central server 100 ). The central server 100 further includes a signal receiving unit 110, an access permission data unit 130, a data comparing unit 120, an access permission data unit 130 and a security level setting unit 140.

A plurality of access control devices are installed in a plurality of areas in a place where it is necessary to limit the access of the persons such as government offices, research institutes, general enterprises, airports and military units. The plurality of access controllers may be assigned respective identification numbers (G-1, G-2 ..... G-n). The plurality of access control devices perform authentication processes of the passengers and the exported goods using the detection sensor 20, which will be described below. The plurality of access controllers selectively allow the access of the user and the exported goods through the authentication process.

The accessing RFID card 11 stores identification information of the accessing person. The accessing RFID card 11 can store the unique ID number of the accessing person.

The article RFID tag 12 stores identification information of the article to be exported. The article RFID tag 12 stores information such as the name of the article to be exported, the tag number, and the content of the other article to be exported.

The sensing sensor 20 senses the RFID tag 11 and the RFID tag 12. The detection sensor 20 is installed in each of a plurality of access controllers.

The security camera 10 captures an image of the face of the passer and an image of the exported article. The security camera 10 is installed in each of a plurality of access controllers.

The central server 100 stores one or more access control unit numbers, which are permitted to enter and exit the outgoing and outgoing goods among the plurality of access control units, and the information of the passengers who are allowed to enter and leave and the products to be exported. To this end, the central server 100 receives the identification information of the passengers sensed by the sensing sensor 20, the identification information of the exported article, the image of the face of the passenger photographed by the camera, and the image of the exported article, And decide whether or not to go in.

The central server 100 includes a signal receiving unit 110. The signal receiving unit 110 receives the identification information of the passengers sensed by the sensing sensor 20, the identification information of the exported product, and the face image of the passenger photographed by the security camera 10.

In addition, the central server 100 includes an access-permitted data unit 130. The access permission data part 130 stores the entrance control unit numbers to which the entrance and exit goods are allowed to enter and exit among the plurality of entrance control units. That is, a passenger who has been permitted to enter at the pre-stored access control number can pass through the exported article permitted to enter and exit.

The central server 100 includes a data comparison unit 120. The data comparison unit 120 compares the information sensed by the signal reception unit 110 and the information stored in the access permission data unit 130. That is, the data comparison unit 120 compares the information of the passerby with the information of the passerby with the information of the passerby with the pre-stored information of the passerby, and judges whether the current passerby and the exported article are in / It is judged whether or not it is passing through the control unit number. If the comparison result does not match, an audible alarm sounds.

Meanwhile, the central server 100 further includes a security level setting unit 140. The security level setting unit 140 sets the security level of the accessing party based on the information on the access frequency to each of a plurality of access controllers of the accessing party. In addition, the security level setting unit 140 sets the security level of the exported product, and according to the security level and the security level, the security level setting unit 140 sets at least one access control unit number information, which is permitted to enter and leave among the plurality of access control units, And transmits it to the control unit 130. [

That is, the security level setting unit 140 calculates the number of access controllers of a plurality of access controllers, and calculates the number of accesses to and exits from the access controllers during a set period. The period can be set in various ways, and can be set to six months or a year. For example, if a certain passer-by always passes an access control device passing through other passengers other than a specific passenger, the security level of the specific passenger is given a relatively low level of security level when the passenger passes the set number of times. The set reference frequency can be variously set to 100 times or 200 times. On the other hand, if an access control device other than a specific accessing passer passes through the access control device over a predetermined number of times during a predetermined period, a relatively high security level is given to the specific accessing person. In this case, it is recognized that only a specific passerby passes to a place with high security.

In addition, the security level setting unit 140 sets the security level of the exported article. The security level setting unit 140 designates an access control unit number to which a passenger holding the exported product can pass based on the security level of the passenger and the security level of the exported product, .

In addition, the security level setting unit 140 of the central server 100 designates a passenger who can carry out the exported goods according to the security level of the passenger. The security level setting unit 140 may include one or more access control devices The time when the exported article is permitted to be exported is specified. For example, it is possible to set a certain passenger to pass 'G-1, G-2' among a plurality of access control devices, and at the same time, set the pass-through item to pass only between 10:00 am and 12:00 am.

The data comparison unit 120 of the central server 100 stores the image of the face of the passenger who is captured by the security camera 10 when the time taken to carry out the exported product is violated or when the pass through of the exported product is not permitted And stores it in the data comparison unit 120 in comparison with the face image of the passenger who is permitted to carry out the later-stored exported article. In case of export violation, beep sounds.

At this time, the central server 100 stores the name of the exported article, the tag number, and the export violation information of the unauthorized removal detection time in the data comparison unit 120, And transmits the export violation information to the phone 30.

The security level setting unit 140 of the central server 100 selects a passenger having a security level matching the security level according to the security level of the exported product and adjusts the security level of the passenger based on the export violation information do. That is, after the set period of six months or one year, the security level for each of the passengers is reset, and the security level is reset according to the degree of the security violation.

At this time, the security level setting unit 140 of the central server 100 sets the working time and the off-hours, and adjusts the security level of the passer-by and the security level of the exported product upward during the off-hours.

The security level setting unit 140 of the central server 100 determines the security level of the unauthorized goods in the non-working hours by using security Level and security level.

The process of allowing the access to the central server 100 and the removal of the central server 100 can be performed as follows. First, a comparison is made between the face image of the passenger photographed by the security camera 10 installed in the entrance control device and the face image of the passenger who is allowed to enter and exit the passenger at the time of taking out the carried article by the passenger, Checks the security level of the user and confirms whether or not the product is allowed to be accessed according to the security level.

Hereinafter, an operation process of an embodiment of the access control system according to the present invention will be described.

It is assumed that the exported item "A" is taken out of the company. At this time, the security level setting unit 140 of the central server 100 has already set the security level for the exported item 'A'. For example, the security level can be set from 1 to 4, and it is assumed that the item 'A' has a security level of 2. In this case, not only the security level information of the second grade is stored in the RFID card of the article 'A', but also the name and the tag number of the article are stored. The information of the 'A' article is transmitted to the access permission data unit 130 of the central server 100.

Since the security level of the item 'A' is class 2, it is necessary to carry out the product to the outside of the company by a person having security level corresponding thereto. The security level setting unit 140 of the central server 100 stores a plurality of users who have already been assigned various security levels.

For example, it is assumed that the security level is set to 1 to 4 according to the security level. At this time, the method of assigning the security level to the passengers is determined according to the number of passengers to pass through and the number of passes through the passengers.

That is, the security level setting unit 140 of the central server 100 sets the security level setting unit 140 of the central server 100 to set the security level of the access control unit to '1', for example, G-1, G-2, G- 2 pass through G-1, G-2, G-3 ...... Gn-2, and the number of accesses passing through each access controller exceeds 100, which is the set reference value. Level can be set. In this case, the security level of the second class is stored in the accessing RFID tag of the passenger of the so-called 'B'. The information of the 'B' accessing party is transmitted from the security level setting unit 140 to the access permission data unit 130.

In addition, the security level setting unit 140 of the central server 100 stores the access controller number to which the exported article is permitted to be entered in advance. That is, the security level setting unit 140 of the central server 100 permits the entry / exit of the article to the passenger of 'B' having the security level corresponding to the security level of the article 'A' . At the same time, the access control data number 130 of the central server 100 designates the access control device number from which the article can enter and exit. For example, an item called 'A' is designated as a 'B' accessor to a 'G-2' access control device. The access time is also specified and transmitted to the access permission data unit 130 of the central server 100. For example, the access time is transmitted between 1:00 pm and 3:00 pm to allow the article to pass through.

The detection sensor 20 not only detects the identification information of the entrance RFID card 11 of the 'B' visitor and the article RFID tag 12 of the 'A' article but also the face image of the 'B' And an image of 'A', which is an article to be exported, and transmits the information to the signal receiving unit 110 of the central server 100.

The data comparison unit 120 of the central server 100 compares the information received by the signal reception unit 110 with the information stored in the access permission data unit 130 to determine whether or not the taken-out article is in or out.

At this time, the data comparison unit 120 of the central server 100 checks the name of the exported article, the tag number of the exported article to be unauthorized for exporting the article "A" to a person other than the person "B" And the export violation information of the unauthorized carry-out detection time, and then transmits the carry-out violation information to the mobile phone 30 of the 'B' visitor. The 'B' visitor who receives this information can confirm the violation of the violation by the company, and in some cases report it when it is judged that a third party other than himself / herself is taking it out.

The above system has the advantage that access control can be effectively enhanced, security clearance can be minimized, and only the access permitted to the accessing person can be allowed to access the accessing entrance.
