Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a password unlocking device for an electric lock, and more particularly to a password unlocking device for inputting a password using a password input circuit installed in a portable terminal.

[0002]

2. Description of the Related Art Conventionally, an electric lock and unlocking device shown in FIG. 2 has been known. In FIG. 2, reference numeral 22 denotes a door phone, which is installed near an entrance door 26 with an electric lock, and a password input device 18 is adjacent to the door phone 22. Reference numeral 24 denotes a master unit connected to the door phone 22 and includes an unlock button 25. The parent device 24 is connected to a password input device 18 and an electric lock 27 provided on an entrance door 26 with an electric lock via an electric lock adapter 23.

[0003] The password input device 18 is mainly installed at the entrance, and is attached while being covered with a lid 20 of a special case 19. By opening the lid 20 of the case 19 and inputting a password with the password input button 21 inside, the electric lock adapter 23 transmits an unlock signal to the front door 26 with the electric lock.
Is sent to the electric lock 27 attached thereto, and the electric lock can be unlocked.

In response to a call from the door phone 22,
The electric lock 27 can be unlocked from the living room by the unlock button 25 from the parent device 24 in the living room.

[0005]

In such an electric lock / unlock device, the location of the password input button is easy to understand, and anyone can easily touch the password input button. In addition, there is a problem in that since the button to be used is dirty, there is a possibility that another person will be able to know the personal identification number from the stain.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem. A portable terminal is connected to a transmission / reception adapter at the time of unlocking, and a personal identification number is input using a personal identification number input circuit installed in the portable terminal. It is an object of the present invention to provide means for realizing an electric lock and unlocking device having higher security by inputting.

[0007]

In order to achieve the above-mentioned object, an electric lock / unlock device according to the present invention comprises a portable terminal such as a mobile phone or a PHS having a password input circuit for inputting a password. An electric lock adapter for controlling the electric lock of the entrance door by judging pass / fail of the set personal identification number and a preset personal identification number, connected between the portable terminal and the electric lock adapter,
A transmission / reception adapter for transmitting the personal identification number input from the mobile terminal to the electric lock adapter is provided.

[0008] In this electric lock password unlocking device, the security can be enhanced by the absence of the password input circuit at the entrance except during use.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of an electric lock / unlock device according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of an electric lock / unlock device according to the present invention.

[0010] A portable terminal 1 such as a portable telephone or a PHS having a password input circuit 8 used for inputting a password, a transmission / reception adapter 2 connected to the portable terminal 1, and an electric lock adapter 7 for inputting the entered password. Password transmission circuit 13 for transmitting to the transmission / reception adapter 2, an unlock LED 9 and an error LED 12 which are installed in the transmission / reception adapter 2 and indicate an unlocked state, an indicator light control circuit 10 for controlling the unlock LED 9 and the error LED 12, and receive the transmitted password. Password receiving circuit 3 for performing
The CPU 4 determines whether the personal identification number of the received personal identification number receiving circuit 3 and the personal identification number set in the personal identification number setting circuit 11 are acceptable or not, and the electric lock control circuit 14 that controls the electric lock 6 of the entrance door. , And an electric lock 6 attached to the entrance door.

When the door is unlocked, the portable terminal 1 is connected to the transmission / reception adapter 2, and a four-digit password is input by a password input circuit 8 such as a push button installed on the mobile terminal 1. The input personal identification number is transmitted from the personal identification number transmitting circuit 13 and received by the personal identification number receiving circuit 3. The PIN received by the PIN receiving circuit 3 and the PIN setting circuit 1
The CPU 4 determines whether or not the password is set in step 1 and matches the password registered in the memory 5. If they match, an unlocking signal is transmitted from the electric lock control circuit 14 to unlock the electric lock 6, a password matching signal is transmitted from the indicator light control circuit 10, and the unlock LED 9 installed on the transmission / reception adapter is turned on. Let it. If they do not match, an input error signal is transmitted from the indicator light control circuit 10 to make the error LED 12 blink.

[0012]

As is clear from the above description, the password unlocking device for an electric lock according to the present invention does not have a password input circuit except at the time of unlocking. Superior in crime prevention.
