3 is a flowchart illustrating a method of operating a door automatic opening and closing system using a GPS signal and a mobile communication terminal.

The mobile communication terminal receives the GPS signal at a time point corresponding to the predetermined period (step 301). Next, the mobile communication terminal calculates a first current position from the received GPS signal (302). The GPS signal is generally transmitted from three or more GPSs, and the automatic door opening and closing system according to the present invention calculates the first current position by triangulation calculation. The calculated first current position is converted into a first position signal as a predetermined signal in a communication form, and transmitted to the door automatic opening and closing system (step 303). In parallel with the first current position, the automatic door opening / closing system receives a GPS signal (step 304) at a time point corresponding to a predetermined period, and calculates a second current position from the GPS signal (step 305). ). Transmission and reception of the automatic door opening and closing system and the mobile communication terminal are performed by being divided into unique identification information such as an ESN and a phone number of the mobile communication terminal. Accordingly, the automatic door opening and closing system has a first current position of the mobile communication terminal and a second current position of the automatic door opening and closing system, and compares the first and second current positions (306). The comparison between the first and second current locations may be generated as a calculated value representing the distance from the second current location to the first current location. The automatic door opening and closing system according to the present invention predetermines and maintains predetermined distance difference information, and compares calculated values calculated from the first and second current positions (step 307).

The first unique identification information is identification information corresponding to the second unique identification information. The door automatic opening / closing system 500 knows in advance whether the first identification information corresponds. When the determination unit 503 determines that the first unique identification information is included in the first infrared signal, the door controller 504 maintains the door automatic opening and closing system in the open state.

In addition, the reception confirming unit 505 confirms the transmission of the first infrared signal based on a predetermined period from the time when the automatic door opening and closing system is kept open, and the first infrared signal is no longer received. In this case, the automatic door opening and closing system is maintained in the closed state by switching from the open state. When the first infrared signal is received and no longer received, it may be determined that the mobile communication terminal approaches the door automatic opening / closing system and moves away.

In addition to the above embodiments, when the second infrared signal is transmitted from the automatic door opening and closing system and the first infrared signal is received as the response data, the open / close state of the automatic door opening and closing system may be controlled. have. This is described in detail in FIG. 6 or FIG. 7.

First, in step 701, the door automatic opening and closing system transmits a second infrared signal at predetermined intervals. The second infrared signal may comprise a predetermined second unique identification information which allows the door automatic opening and closing system to be distinguished independently from other door automatic opening and closing systems. Next, in step 702, the predetermined mobile communication terminal receives the second infrared signal and checks whether it contains the second unique identification information. The second unique identification information is unique identification information corresponding to the first unique identification information maintained by the mobile communication terminal, and the mobile communication terminal knows in advance that the second unique identification information corresponds to the first unique identification information. Should be The mobile terminal determines whether the second infrared signal includes the second unique identification information (step 703), and if the second infrared signal does not include the second unique identification information, step 702 Perform Step 702 is executed when a second infrared signal is received from the automatic door opening / closing system, and the mobile communication terminal according to the present invention does not manage the automatic door opening and closing system when the second infrared signal is not received.
