Hereinafter, a door lock opening and closing device using a mobile phone according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a door lock opening and closing apparatus using a mobile phone according to an embodiment of the present invention. As shown in FIG. 1, a door lock opening and closing apparatus using a mobile phone according to an embodiment of the present invention includes a battery 1 for supplying operating power and a mobile phone driving circuit operated by receiving driving power from the battery 1. (3), a keyboard 5 for inputting a user's command to drive the mobile phone driving circuit 3, and a password for opening and closing a door lock (not shown) input by the keyboard 5; A microprocessor 7 for controlling operation, a use mode setting switch 9 for selecting one of a telephone call and a door key function, and an oscillator for oscillating and inputting a clock of a predetermined period to the microprocessor 7 ( 10), the EEPROM 11 storing the password for opening and closing the electronic door lock input by the keyboard 5, and the door key function being set by the use mode setting switch 9 The amplifier 13 receives and amplifies the password for opening the electronic door lock output from the EEPROM 11 by the control of the microprocessor 7, and the electronic door lock for receiving the password data amplified by the amplifier 13. It is provided with a drive means 17 for outputting through the antenna 15 to open the.

Next, the operation and effect of the door lock opening and closing apparatus using the mobile phone according to the embodiment of the present invention configured as described above will be described.

Figure 2 is a flow chart illustrating the opening and closing of the door lock using a door lock opening and closing device using a mobile phone according to an embodiment of the present invention. In FIG. 2, S denotes a step.

First, in step S1, a password is input to the door lock and the microprocessor 7 of the mobile phone (not shown) using the keyboard 5 to set a password to the door lock, and at the same time, the microprocessor 7 of the mobile phone. Set a password in the EEPROM 11 (password setting step), and proceed to step S2 to determine whether the use mode is set to the open mode of the door lock by the use mode setting switch 9 (use mode discrimination). Step) If the use mode determination step determines that the use mode is set to the open mode of the door lock (YES), proceed to step S3 and enter the password using the keyboard 5 of the mobile telephone ( Enter password).

Next, the process proceeds to step S4, when the password input in the password input step is received by the microprocessor 7 and processed to be the same as the password previously stored in the EEPROM 11, the password output from the microprocessor 7 The data is amplified by the amplifier 13 and output from the transmitting means 17 to the door lock wirelessly through the antenna 15 (password wireless sending step).

Subsequently, the flow advances to step S5 to determine whether the password data sent out in the password wireless transmission step matches the password stored in the door lock in advance (password determination step), and is previously stored in the door lock in the password determination step. If the password matches the password, the flow advances to step S6 to open the door lock (door lock opening step).

Closing the door lock is done by closing the door.

On the other hand, if the use mode determination step of step S2 determines that the use mode is not set to the open mode of the door lock (NO), the operation returns to step S2 and the operation below the use mode determination step of step S2 is repeated. In the password determination step of step S5.

As a result of the determination of the password wireless transmission step, if the password data sent from the mobile telephone does not match the password stored in advance in the door lock, the process returns to step S3 and the operations following the password input step of step S3 are repeatedly performed.

In the above description, the input of the password is button number 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, *, #, A, B, C, D, --- Z of the keyboard 5. Can be stored using
