The electronic lock apparatus using the portable terminal of the present invention thus constructed performs the following operation on the release control of the door.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 1 to 3.

First, when the portable terminal is started, the first CPU 51 of the transmitter 50 initializes the mode system (ST10). After initialization, the first keypad 52 is operated (ST11).

When key data is input by the operation of the first keypad 52, the first CPU 51 searches whether the lock key 52b shown in Fig. 2 is input (ST12). If there is no input of the lock key 52b in step ST12, the normal call mode routine is executed (ST13). When the lock key 52b is input in the above, it is searched whether the setting key of the password is input (ST14). That is, it searches for which one of the plurality of numeric keys of the first keypad 52 is set by shortening the password. When the corresponding numeric key with the password set is input and then the call key 52a is input (ST15), the first CPU 51 is assigned to the selected numeric key among a plurality of passwords stored in the first memory 53. The corresponding password is read and provided to the encoder unit 56.

The encoder 56 encodes the password inputted from the first CPU 51 (ST16) and provides it to the frequency synthesizer 55, and the frequency compressor 55 is configured to After combining the coded password data input from the encoder unit 56 by the control to a high frequency signal, power amplification to a sufficient size through the transmission high-frequency amplifier 57 and unnecessary signal components through the transmission filter 58 It removes and transmits through the antenna ANT1 (ST17).

Thereafter, it is checked whether the data transmission of the password is completed (ST18). If the transmission is not completed, the process after the step ST15 is repeated, and if the transmission is completed, it is searched whether a new setting key (numeric key) has been input ( ST19). When a new setting key is input in step ST19, this is for unlocking another door, and thus repeats the process after step ST14 to send a new password to the receiving device 60. If no new setting key is input in step ST19, the lock mode is completed.

On the other hand, if the lock key 52b is input in step ST12 (ST14) and there is no input of the password setting key, it is searched whether or not the astrisk key (*) 52c as shown in FIG. 2 is entered (ST20). If there is no input, the process after step ST11 is performed, and if there is an input of a key, it is determined as a mode for additional registration of another password, and a message for inputting the registration password to be added is displayed on the first LCD. In this way, when a password to be added and a setting key (numeric keys) are input (ST22), the first CPU 51 additionally registers at a corresponding address of the first memory 53 corresponding to the selected numeric key. The password is stored (ST23), the password and the asterisk key (*) are encoded (ST24), and transmitted to the receiving device 60 through the process after the above step ST16.

On the other hand, the receiver 60 coupled to the door initializes the system in order to receive the high frequency signal from the transmitter 50, as shown in Fig. 3B (ST30). After the initialization is canceled, a high frequency signal transmitted from the transmitter 50 is received through the antenna ANT2 (ST31). The received high frequency signal is removed by unnecessary noise components through the reception filter unit 68, and amplified to a sufficient magnitude in the reception high frequency amplifier 67 and input to the data extraction unit 65.

The data extraction unit 65 extracts Asterisk key (*) data and password data from the input high frequency signal (ST32) and provides it to the decoder unit 66, and the decoder unit 66 supplies the extracted data to the original data. The process is restored to (ST33) and provided to the second CPU 61.

The second central processing unit 61 retrieves whether or not the astrisk key (*) data, which is restored from the decoder 65 to the original data, is input (ST34).

If the Asterisk key (*) data is input in step ST34, it is determined as a mode for registering an additional password, and the input password is registered in the second memory 63 (ST39). If there is no input of Asterisk key (*) data in step ST34 and only a password is input, it is determined as the unlock mode of the door, and the password registered in the second memory 63 is read and matched with the received password. Determine (ST35).

If the two passwords do not match in step ST35, a message prompting the user to re-enter the password is visually displayed on the screen of the second liquid crystal display 64, and the process ends (ST36). When the two passwords match at step ST35, the magnetic key 70, which receives the operating voltage from the power supply unit 71, is driven (ST37) to release the door (ST38).

In order to correct the password registered in the first memory 53 of the transmitter 50 and the second memory 63 of the receiver 60, the menu key of the first keypad 52 shown in FIG. Press to display the password registered in the first memory 53 on the screen of the first liquid crystal display 54, and then erase the password through the erase key while moving the cursor movement key 52e to the left and right.

The erased data is sent to the receiver 60 in the same manner as described above to erase the corresponding password registered in the second memory 53.

In addition, reference numeral 62 in the drawing denotes a second keypad part provided in the receiving device 60. When the portable terminal loses its function when the portable terminal loses its function, for example, when the portable terminal loses its function, for example, the transmitting device 50 is insufficient. When not operating or carrying a portable terminal, the user presses a numeric key (password) directly to unlock the door.

On the other hand, as a comparative example, unlike the prior art, that is, to unlock the door by inserting a mechanical key or an electronic card into the door lock device and the electronic lock device, the present invention corresponds to a password of various types registered in the portable terminal. Select the password of the door and transmit it on the high frequency signal, and the receiving device coupled to the door extracts the password from the high frequency signal transmitted from the portable terminal and unlocks the door only when it matches the password registered in its memory. It can be seen that.

As a result, according to the present invention, since various types of doors can be unlocked by wireless communication between the transmitting device of the portable terminal and the receiving device coupled to the door, there is an advantage of not having to carry several unlocking keys.

In addition, while specific embodiments of the present invention have been described and illustrated above, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.

According to the electronic lock apparatus using the portable terminal of the present invention, which is apparent from the above description, the present invention can unlock various types of doors through wireless communication between the transmitting apparatus of the portable terminal and the receiving apparatus coupled to the door. The inconvenience of having to carry several decommissioning keys for the purpose of use is eliminated, and the high frequency signal has the effect of maximizing the prevention of theft by the convenience and the inability to copy the door at close and long distances.
