Various types of locking systems are used in a variety of fields, from homes to private businesses, laboratories, and companies. Many types of locking systems are currently used, ranging from simple, inexpensive mechanical locks to expensive mechanical and electronic devices that combine mechanical mechanisms and electronic technology.

As a locking system combining expensive mechanical and electronic devices, a locking system using a contact card that records personal information on a magnetic stripe or a contactless card of a radio frequency induction method is used. As a more secure lock system, an access control system using biometric technology such as fingerprint recognition, iris recognition, and vein recognition has been developed and used. Expensive locking systems are recognized for their high security because they are difficult to imitate, but they are expensive to install in general places.

Meanwhile, in order to provide a more convenient environment for use, a locking system using a wireless remote controller is provided. Wireless car door opening and closing device which is generally used is an example. The wireless open / close lock system is provided in various functions and forms. As a technology related to a locking system using a remote controller, there is a door lock device using a Korean Patent Publication No. 1999-0086587, and a door lock device of a Korean Patent Publication No. 1999-0036546.

They provide convenience in that they can remotely control the locking and unlocking of the door, and they do not provide a separate locking means such as a keyhole or a unlocking key. Provides the effect of preventing

However, until now, the lock system of the wireless control method uses a remote controller with a built-in password, and when the on / off button provided in the remote controller is input, the built-in password is transmitted wirelessly. Therefore, if the remote controller with a built-in password is lost, there is a disadvantage that it cannot prevent the use of others who have acquired it. In addition, the locking system also controls the opening and closing of the door by using a radio signal of a fixed specific frequency band, in which case it is difficult to prevent its imitation when a fixed specific frequency is exposed.

As described above, the wireless remote control locking system has an advantage that it can be supplied at a relatively low cost with ease of use. However, it is recognized that there is a problem in security because it is difficult to prevent the loss of the remote controller or theft of a specific frequency used. Therefore, there is a need for a locking system that can maintain high security while maintaining its convenience in using a wireless remote controller.

Accordingly, an object of the present invention is to provide a locking system that can open and close a door by using a wireless remote controller without a password as proposed to solve the above-mentioned problems.

As described above, the lock system having the wireless remote controller of the present invention can prevent the invasion of others who have acquired the remote controller even if the remote controller is lost because a password is not embedded in the remote controller. In order to provide higher security, the remote controller may encode and transmit the password and decode it at the receiving end. If the encoding / decoding process is performed at the time of password transmission / reception, even if the frequency used by the remote controller is exposed, it will be difficult to imitate the password unless the encoding and decoding methods are exposed.

In the locking system of the present invention, encoding and decoding may be performed when a password is transmitted and received to secure higher security. An operation process of the locking system of the present invention to which an encoding and decoding process is added will be described in detail.

8 is a flowchart illustrating an operation procedure to which an encoding / decoding process is added when a password is transmitted and received in the lock system of the present invention.

1 and 8, when the user inputs a password through the input unit 12 of the remote controller 30 in step S20, the remote control unit 14 encodes the password input in step S22 and then the transmitter 16. To transmit wirelessly. In step S24, the system controller 24 receives the encoded password through the receiver 22, decodes and restores the password encoded in step S26. Then, the password decoded in step S28 and the password 25 stored in the memory 26 are compared to determine whether they match. If there is a match, the lock state of the locking device 28 is released in step S30.

As the encoding and decoding process is performed at the time of transmitting and receiving the password, it is difficult to imitate the password even if the transmitting and receiving frequency is exposed.

On the other hand, when the remote controller 10 is lost or broken and cannot be used, a method for opening the door is required. 9 is a block diagram showing the overall circuit configuration of a locking system with an emergency input port.
