Abstract

PURPOSE: A locking system for using a portable phone as a key using a CID(Caller ID) is provided to make a CID terminal recognize a specific input number when a user makes a call using his portable phone, so that the portable phone can be used as the key of a lock. CONSTITUTION: A locking system for using a portable phone as a key using a CID consists of a CID terminal(10), an output part(20), a relay control part(30), a relay(40), and a motor-operated lock(50). The CID terminal(10), connected with the output part(20), the relay control part(30), the relay(40) and the motor-operated lock(50), comprises a CPU(1), a ROM(2), a RAM(3), an input part(4), an output part(5), a control switch(6), a CID signal analysis part(7), a key analysis part(8), and an LCD(9). The output part(20) outputs a signal to unlock a lock. The relay control part(30) amplifies the signal and operates the relay(40). The relay(40) serves as a switch to operate the motor-operated lock(50).

Description

Lock using your phone as a key with caller ID {omitted}

The present invention uses an electric lock to dial a cell phone by using a caller ID that allows the user of the same cell phone to open the lock by inputting a password into a cell phone using a caller ID service. It is about a lock device used as a.

The caller display apparatus used in the related art is simply used as a simple function of inputting only the number of the calling party, and there is no other special function.

In the case of a lock, it is used only by a simple function of opening the lock by pressing a switch that is opened using a key from the outside or using electricity in the room.

In this case, the same lock has to be carried by all the people, so it is cumbersome, and if the key is lost, it is inconvenient to open the lock as soon as necessary and there is a problem of duplicating the key again or replacing the entire lock.

In addition, although there is a radio wave key using a radio wave, it has a disadvantage in that it is difficult to use it, such as having to carry a radio transmitter which serves as a key and requesting a producer to duplicate a key when it is lost or when another key is needed.

In order to solve this inconvenience, the present invention allows the caller display device to recognize a specific input number by detecting the caller's display when the user makes a phone call with the user's mobile phone. It is safe from contamination and destruction caused by the exposure of the lock as it removes the key part exposed to the lock.

In addition, only a mobile phone with a specific phone number can play a key role, so it is impossible for others to duplicate the key. It is an object of the present invention.

The present invention processes a CPU 1 for recognizing, connecting and controlling a program, a ROM 2 for storing a program, a RAM 3 for storing data necessary for a program, an input unit 4 for processing input signals, and an output signal. The output unit 5, the control switch 6 capable of controlling the function, and the CID signal analysis unit 7 for interpreting the CID signal of the telephone line. The telephone key analysis unit 8 for interpreting the telephone key input. The CID (10) portion of the caller display device, consisting of an LCD (9) showing the output unit 20 for outputting the unlocking signal and the relay control unit 30 to amplify the signal to operate the relay and The relay 40, which serves as a switch for operating the electric lock, and the electric lock 50 may be connected.

In order to use the present invention as described above, in order to recognize the user's mobile number on the caller display device, the phone number must be memorized and a step of memorizing a password, which is first performed as a user's phone number input step. As shown in the flowchart of Fig. 3, when the telephone number is input and all the number keys of the telephone number are input and the command is terminated, the accumulated key number is input into the RAM 3 and the telephone number is recorded.

Then, as a step of memorizing the password number, as shown in the flowchart of FIG. 4, the input is started, the password number keys are all input, and the command is terminated. The accumulated key number is input to the RAM 3, and the password ends.

The command program is already stored in the ROM 2 which stores the program.

By repeating the above, multiple people can use the same lock simultaneously by entering their mobile phone number and password on their mobile phones.

In this way, when the user's mobile number and password are entered, when the call is made to the caller display side where the device is installed, the caller display device is recognized when the call is received to recognize the caller's phone number to activate the electric lock. When the caller ID is recognized by the input unit 4, the caller number is compared with the caller number inputted into the RAM 3 by the phone key analyzer 8.

In this case, if it is not the key-designated phone number entered in advance, the CPU (1) command will immediately transfer to the normal phone.If it is the same as the key-designated phone number entered, proceed with the next command to standby. Enter.

At this time, the received telephone number and password are interpreted by the CID signal analyzing unit 7 and displayed on the LCD 9 portion.

When the password is input, the cumulative key number is received and compared with the previously input password and the CID signal analysis unit 7.

Here, if the password is incorrect, it waits for a key input command again, and if the password is the same, it is transmitted to the output unit 20 which outputs a signal for unlocking the lock. When the next signal is sent to the relay control unit 30, the control unit relays 40 Signal to open the lock (50).

In the present invention as described above, the telephone caller indicator and the telephone caller indicator can be used as a telephone.

In the present invention, the user does not have to carry a device that functions as a key, but uses a mobile phone commonly used as a key role to serve as a key role. The effect is that you do not have to carry, and even if you lose the key, you only need to open it with the original phone number. Likewise, if you need more keys, the new phone number can be stored in the phone number memory of the lock.

In addition, the present invention has the effect of preventing the risk of contamination and damage since the number of the input portion is made of a telephone line to minimize the functional part of the lock device, and the lock device does not operate unless the telephone having the calling party's telephone number that serves as a key It is effective in maintaining security.
