BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an access management system (ARP)
3 is a flowchart of an access management method using an ARP table according to a preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an access management system using an ARP table according to embodiments of the present invention and its access control method will be described in detail with reference to the accompanying drawings.

It should be understood that the following embodiments of the present invention are only for embodying the present invention and do not limit or limit the scope of the present invention. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

Before describing the access management system 100 using the ARP table of the present invention and its access management method, the ARP (Address Resolution Protocol) will be briefly described.

ARP is a protocol used to map IP addresses to physical network addresses on a network. Where the physical network address is the 48-bit network card address of the Ethernet or Token Ring, also called the Mac Address.

For example, if IP host A tries to send an IP packet to IP host B and does not know the physical network address of IP host B, an ARP packet with destination IP address B and broadcasting physical network address FFFFFFFFFFFF To the network. IP host B responds to A with its physical network address when its IP address receives an ARP packet at its destination.

The IP address and the corresponding physical network address information collected in this manner are stored in a table in a memory called an ARP cache of each IP host, and then used again when the packet is transmitted. Contrary to ARP, if an IP host knows its physical network address but does not know the IP address, it uses RARP to request an IP address from the server.

The gateway device is a gateway device equipped with a function capable of grasping ARP information. The gateway device includes a LAN (or Wifi), a home appliance 300b in a home or an office, and a ZigBee or a JigWave Module can be mounted.

The access management system 100 using the ARP table of the present invention can be implemented using this gateway device.

FIG. 1 shows a configuration of an access management system 100 using an ARP table according to a preferred embodiment of the present invention. FIG. 2 is a diagram illustrating an operation of the access management system 100 using the ARP table according to an exemplary embodiment of the present invention.

1 and 2, an access management system 100 using an ARP table according to a preferred embodiment of the present invention will be described.

The access management system 100 using the ARP table according to the preferred embodiment of the present invention includes a storage unit 110, a determination unit 120, and a control unit 130 as a gateway device.

The storage unit 110 stores a physical network address of at least one device 300a or 300b registered in advance.

Specifically, the storage unit 110 stores the physical network addresses of the mobile terminal 300a and the network home appliance 300b, such as a smartphone such as resident / office worker in the home. The home appliance 300b or the mobile terminal 300a corresponding to each physical network address can be detected and checked using the information stored in the storage unit 110. [

Next, the determination unit 120 determines the status of at least one of the devices 300a and 300b connected to the router 200 using the network ARP table. The determination unit 120 can check the current state of a user such as a resident / office worker in the home by looking at the network ARP table connected to the network router 200 in the home or office. More specifically, the determination unit 120 analyzes the ARP table list file to determine the physical network address and the IP address connected to the router 200. That is, the determination unit 120 can grasp, through the ARP table list, the status of the mobile terminal 300a such as resident / office worker in the home and the network home appliance 300b connected to the network router 200. The determination unit 120 may store the connection information with the router 200 in a database in the gateway. It is needless to say that the ARP table is updated at predetermined time intervals, and the determination by the determination unit 120 needs to be made again.

The determination unit 120 determines whether the mobile terminal 300a is connected to the router 200 when at least one mobile terminal 300a among the at least one devices 300a and 300b registered in the storage unit 110 exists. The user of the mobile terminal 300a determines that the user of the mobile terminal 300a is re-occupied in the corresponding space.

The control unit 130 controls the operation of at least one of the devices 300a and 300b using the determination result of the determination unit 120. [

The control unit 130 turns off the operation power of at least one of the devices 300a and 300b that is set in advance as a result of the determination by the determination unit 120, do. For example, in the case of a heating device or a cooling device, it is preferable that the power supply is turned off when there is no occupant in the room. In this case, the heating device or the cooling device can be set in advance to the devices (300a, 300b) whose power is off in the absence of a room occupant. Accordingly, it is determined by the judging unit 120 that no one is in the room. If the set heating device or the cooling device is operating, the power of the heating device or the cooling device can be automatically turned off.

In addition, if it is determined by the determination unit 120 that there is a user who is set in the management mode in advance among the users whose access to the space is detected, the controller 130 transmits the information to the administrator terminal 400 Do. For example, an elementary school student is set to the management mode, and when the elementary school student returns home, information can be checked by returning information to the terminal of the mother. Or, if an elementary school student joins the school to attend class, it can check whether or not attendance is possible by sending information to the mother's terminal. In addition, the entrance / exit of the space can be detected simply by determining that the user who has not been re-entered has entered the space when the user changes to the re-room, and has gone out of the room if the user who has re-entered has changed to not re-entering.
