The present invention relates to a method for registering and deleting a wireless transceiver in a digital door lock. More specifically, a wireless transceiver registration method in which a digital door lock searches for, receives, and registers a registration request signal from a wireless transceiver, and then transmits a registration completion signal to the wireless transceiver, and transmits a test signal from the digital door lock to the wireless transceiver. If not, the present invention relates to a radio transceiver deletion method for deleting registration information of a radio transceiver without a response.

Conventionally, mechanical door locks for opening and closing doors using metal keys have been mainly used as door opening and closing devices for offices, hotel rooms and apartments. However, the conventional mechanical door lock was weak in security because the metal key used as an authentication means is vulnerable to loss and duplication. Nowadays, a digital door lock is used to control the overall unlocking and deciding operation of the door lock by using an electronic key as an authentication means to solve the vulnerability of the conventional mechanical door lock, and by mounting a microprocessor unit (MPU) in the door lock. It is developed and commercialized. Moreover, digital door locks using a wireless transceiver have become commonplace for the purpose of remotely controlling the overall operation of digital door locks, for example, the unlocking and locking operations of the digital door locks.

1 is a diagram of a digital door lock operated using a wireless transceiver.

The wireless transceiver 120 transmits a control signal for unlocking and locking operation to the digital door lock 110. To this end, the wireless transceiver 120 has a built-in communication means for communication with the digital door lock 110. In addition, the digital door lock 110 also incorporates the same kind of communication means as the wireless transceiver 120.

Here, as a communication method between the wireless transceiver 120 and the digital door lock 110, a communication method using an RF signal, an infrared signal, a laser signal, etc. may be used, but RF signals are used a lot for omnidirectional characteristics and cost reduction. do.

When the digital door lock 110 having a wireless transmission / reception function is first installed, or when the wireless transceiver 120 is used for the first time, or when the wireless transceiver 120 is lost and the separate wireless transceiver 120 is purchased, the user may wirelessly The registration button provided in the transceiver 120 must be operated to register the digital door lock 110.

The registration method according to the prior art of the wireless transceiver currently used in the digital door lock 110 is as follows. First, the user changes the digital door lock 110 to the registration mode, and then manipulates the registration button provided in the wireless transceiver 120. The wireless transceiver 120 transmits a registration signal including an ID to the digital door lock 110, and the digital door lock 110 stores the received registration signal in an internal memory unit. Through the above process, the wireless transceiver 120 is registered in the digital door lock 110, and then it is possible to control the digital door lock 110 only by button operation.

On the other hand, when the wireless transceiver 120 is not required in the use of the digital door lock 110, the digital door lock 110 should delete the registered wireless transceiver 120. Currently, the wireless transceiver deletion method used in the digital door lock 110 is similar to the aforementioned registration method.

The wireless transceiver 120 transmits a deletion signal to the digital door lock 110, and the digital door lock 110 deletes the registered wireless transceiver information from the memory unit according to the received deletion signal.

However, since the registration and deletion of the wireless transceiver 120 through such a step is performed by a method of transmitting a registration signal or a deletion signal to the digital door lock 110 in one way, the digital door lock 110 is If a registration signal or a deletion signal is not properly received, a registration error or a deletion error may occur, and if the user does not recognize the error and does not operate according to the wireless transceiver 120 later, the wireless transceiver 120 may be broken. In this case, it becomes difficult to determine whether a registration error situation exists. In addition, when registering or deleting the wireless transceiver, since the digital door lock 110 is automatically released from the registration mode or the deletion mode after a certain time, it is inconvenient for the user because the registration or deletion must be completed within a predetermined time.

In addition, since the delete operation is performed through the input of the delete button of the wireless transceiver 120, when the wireless transceiver 120 is broken, the delete operation cannot be performed and the registration information remains in the digital door lock 110. In addition, since the registration information is continuously stored in the digital door lock 110 even when the wireless transceiver 120 is lost, a situation in which a person with impure intention acquires the wireless transceiver 120 may invade. have.

In order to solve the above problems, the present invention provides a wireless transceiver registration method in which a digital door lock retrieves a registration request signal from a wireless transceiver, receives a signal, and transmits a registration completion signal to a wireless transceiver, and a test signal from a digital door lock to a wireless transceiver. It is an object of the present invention to provide a method for deleting a radio transceiver to delete registration information of a radio transceiver without a response when transmitting no response.
