DIGITAL DOOR-ROCK SYSTEM AND CONTROL METHOD THEREOF

The present invention relates to a digital door-lock system and a control method thereof, and more particularly, to a digital door-lock system and a control method thereof by controlling a wireless communication method to shorten the execution time of the door-lock release function.

Door-lock systems are installed in homes and offices to restrict entry or prevent outsiders from entering. These door-lock systems are expensive mechanical door-lock systems with complex mechanical mechanisms in simple low-cost locks. And mechanical and electronic door-lock systems that combine electronic technology with mechanical mechanisms.

Mechanical and electronic door-lock systems include a door-lock system using a keypad input and a card-type door-lock system using cards such as magnetic cards, radio frequency (RF) cards and integrated circuit (IC) cards. It is widely spread.

Most card-type door-lock systems are encoded with authentication information stored in the card to determine whether or not to permit access, and the door is opened and closed by reading authentication information inside the card through a card reader.

On the other hand, mechanical and electronic door-lock system can be largely divided into contact and contactless. Contact type is a method of releasing the door by contacting the door-key to the door-lock body mounted on the door. However, in the case of the contact type, in order to open and close the door, the door-key must be taken out of the user's pocket or the like and directly contacted.

Such contact door-lock systems are gradually evolving into contactless door-lock systems, which allow the door-lock body to open and close the door by receiving authentication information from the door-key, for example, a smart-key carrying. do.

The non-contact door-lock system affects various factors such as door release operation time and battery consumption, depending on how the door-lock body recognizes the smart-key. The study of the non-contact door lock system considering these factors is ongoing.

According to an embodiment of the present invention, there is provided a digital door-lock system and a control method thereof, which shorten the execution time of a door-lock release function and improve convenience for a user.

In addition, according to an embodiment of the present invention, there is provided a digital door-lock system and a control method thereof that can simplify the operation process to optimize the door-lock system.

The digital door-lock system of the present invention comprises a plurality of smart-keys for receiving an authentication request signal transmitted by the door-lock body and being activated, and transmitting a response signal to the door-lock body; And a door-lock body configured to receive a response signal transmitted by one smart-key of the plurality of smart-keys to perform a door-lock release operation, wherein each of the smart-keys is a smart-key. When the standby time from the time after activation to the predetermined time is set differently, each smart-key transmits the response signal to the door-lock body when there is no response signal of the other smart-key during its own standby time, the door The lock body may perform a door lock release operation in response to the response signal.

The time points at which the plurality of smart-keys receiving the authentication request signal from the door-lock body are activated are the same.

After the door-lock body transmits the authentication request signal, the smart-key having the shortest waiting time among the plurality of smart-keys receiving the authentication request signal transmits the response signal to the door-lock body. It features.

Among the plurality of smart-keys receiving the authentication request signal, other smart-keys other than the smart-key with the shortest waiting time detect the response signal of the smart-key with the shortest waiting time and switch to the standby mode. It features.

The waiting time may be shorter than a length of the authentication request signal and the response signal.

The plurality of smart-keys is characterized in that three or more.

The control method of the digital door-lock system of the present invention includes the steps of: the door-lock body transmitting an authentication request signal; Waiting for a preset waiting time after the smart-key is activated by receiving the authentication request signal transmitted from the door-lock body; Determining whether the smart-key has a response signal of another smart-key during the waiting time, and transmitting a response signal to the door-lock body when there is no response signal of the other smart-key; Receiving, by the door-lock body, the response signal; And releasing the door-lock by authenticating the response signal by the door-lock body.

When the door-lock release request is input from the user to the door-lock body, the door-lock body may transmit the authentication request signal to the smart-key.

When a plurality of smart-keys having different waiting times receive the authentication request signal transmitted from the door-lock body, the smart-key having the shortest waiting time among the plurality of smart-keys is transmitted to the door-lock body. Characterized in that the transmission of the response signal.

Hereinafter, the present invention will be described in detail.

The present invention can control the operation method of the digital door-lock system to quickly perform the door-lock release and simplify the system. The digital door-lock system of the present invention, for example, after receiving the authentication request signal transmitted by the door-lock body and activated, a plurality of smart-keys and the plurality of smart to transmit a response signal to the door-lock body And a door-lock body configured to receive the response signal corresponding to the authentication request signal transmitted by one of the smart-keys and perform a door-lock release operation.

Here, the plurality of smart-keys are set differently from each other after the activation of each smart-key to a certain time. Each smart-key determines the presence or absence of a response signal of another smart-key during its preset waiting time, and transmits its response signal to the door-lock body when there is no response signal of the other smart-key.

Accordingly, the door-lock body confirms the validity of the received response signal and, if authenticated, performs the door-lock release operation.

Here, the plurality of smart-keys receiving the authentication request signal from the door-lock body are all activated at the same time to perform a wake-up function. That is, a plurality of smart-keys in a predetermined area capable of receiving a signal of the door-lock main body receive an authentication request signal, for example, an authentication request signal in the form of an LF signal and are activated at the same time.

Here, the plurality of smart-keys may be three or more. That is, the digital door-lock system of the present invention solves the inconvenience that the door-release operation execution time is delayed as the number of smart-keys is used in the conventional door-lock system.

The smart-keys receiving the authentication request signal of the door-lock body wait for a preset waiting time, and each smart-key has its own response signal when there is no response signal of another smart-key during its own waiting time. To the door-lock body.

Therefore, when a plurality of smart keys set with different waiting times receive the authentication request signal of the door-lock body, the smart-key having the shortest waiting time among the plurality of smart-keys transmits a response signal to the door-lock body. Will be done.

Here, when the smart-key having the shortest waiting time among the smart-keys receiving the authentication request of the door-lock body transmits a response signal to the door-lock body, the smart-key other than the smart-key having the shortest waiting time is transmitted. Detects the response signal of the smart-key having the shortest waiting time during its waiting time and switches to the standby mode without going through the process of sending its response signal to the door-lock body.

That is, the digital door-lock system of the present invention sets a unique waiting time for each of the plurality of smart-keys, and accordingly performs the authentication process by quickly recognizing the smart key in the signal receiving area of the door-lock body. Through the authentication process for each smart-key, it is possible to overcome the disadvantages of the conventional method, which has been limited in time.

Such a digital door-lock system of the present invention has an effect of further shortening the door-lock release operation time in the door-lock system using three or more of the plurality of smart-keys, and also of the plurality of smart-keys Each preset waiting time is shorter than the above-described authentication request signal and response signal, thereby further shortening the door-lock release operation process time.

Subsequently, the door-lock body receives the response signal transmitted by the smart key having the shortest waiting time, confirms the validity of the response signal, and releases the door-lock when authentication is completed.

As described above, the digital door-lock system according to an embodiment of the present invention may quickly perform the door-lock release operation by setting different waiting times of each of the plurality of smart-keys. That is, the digital door-lock system of the present invention directly transmits the authentication request signal to all of the conventional smart-keys, omits the process of waiting for the response signal, and immediately sends the authentication request signal to the smart-key that wants to release the door-lock. The transmission simplifies and speeds up the operation of the digital door-lock system. This minimizes power consumption and optimizes the digital door-lock system.

Here, since the waiting time preset for each of the plurality of smart-keys is shorter than the length of the authentication request signal and the response signal, the door release process may be performed more quickly.

One embodiment of such a control method of the digital door-lock system of the present invention is as follows.

First, the door-lock body transmits an authentication request signal. Thereafter, the smart-keys in a predetermined area capable of receiving a signal transmitted by the door-lock body are activated by receiving an authentication request signal transmitted by the door-lock body.

After that, each smart-key waits for a preset waiting time, and each smart-key determines the presence or absence of a response signal of another smart-key during its waiting time after its own waiting time. If there is no response signal, the response signal is transmitted to the door-lock body.

For example, among the smart-keys receiving the authentication request signal of the door-lock body, the smart-key having the shortest waiting time recognizes that there is no response signal of the other smart-keys during its waiting time, and receives its own response signal. Transfer to the door-lock body.

Smart-keys other than the smart-key with the shortest waiting time detect the response signal of the smart-key with the shortest waiting time, and do not transmit its response signal to the door-lock body, and switch to the standby mode. . The presence or absence of a response signal of the other smart-keys may be made through the door-lock body.

Thereafter, the door-lock main body receives the above-described response signal and goes through a procedure of checking whether the response signal is valid and then releases the door-lock when authentication is completed.

Here, the door-lock body may receive a door-lock release request input from the user before transmitting the authentication request signal. That is, when the user wants to release the door, the door-lock body may request the door-lock release. For example, a user may input a door-lock release request to the door-lock body by pressing a button installed on the door-lock body. have.

Only when the door-lock release request is input from the user to the door-lock body, the door-lock body transmits the authentication request signal to the smart-key, thereby minimizing power consumption.

The digital door-lock system of the present invention can operate as described above to shorten the door release operation time. That is, a plurality of smart-keys preset a different waiting time from a plurality of smart-keys after being activated by receiving a start signal to a certain point in time, and receiving the authentication request signal transmitted by the door-lock body. The smart key, which has the shortest waiting time, transmits the response signal to the door-lock body, thereby simplifying the door release process and minimizing the operation time of the digital door-lock system.

Accordingly, the digital door-lock system of the present invention can increase the convenience by providing a quick door release process to the user and optimize the system by minimizing power consumption.

The digital door-lock system and its control method according to the present invention has an effect of shortening the door-lock function execution time.

In addition, the digital door-lock system and its control method according to the present invention has the effect of simplifying the operation process to provide convenience to the user.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. However, the scope of the present invention is not limited by the following examples. In addition, in describing this invention, the same code | symbol is attached | subjected to the same code | symbol and the repeated description is abbreviate | omitted.

The digital door-lock system of the present invention operates by performing a communication function between the smart-key and the door-lock main body. Referring to one embodiment of a process in which the digital door-lock system of the present invention operates, FIG. Is the same as

1 is a diagram illustrating a digital door-lock system according to an embodiment of the present invention.

As shown in FIG. 1, a digital door-lock system according to an embodiment of the present invention includes a door-lock body 100 and a smart-key 120 that is a portable device.

Door-lock body 100 according to an embodiment of the present invention is the power supply 101, the sensor unit 102, the door opening and closing unit 103, the memory 104, the control unit 105, the keypad unit 106, It includes an LF transmitter 107 for transmitting the authentication request signal in the form of an authentication request signal, for example, LF signal, and an RF receiver 108 for receiving a response signal in the form of a response signal, for example, RF signal.

In addition, the smart-key 120 according to an embodiment of the present invention is the power supply unit 123, the memory 122, the control unit 124, the keypad unit 121, authentication request signal, for example, authentication request in the form of LF signal LF receiving unit 126 for receiving a signal and a response signal, for example, RF transmitter 125 for transmitting a response signal in the form of an RF signal.

For example, when the sensor unit 102 of the door-lock main body 100 receives a door-lock release request from the user, the LF transmitter 107 may authenticate the smart-keys in a predetermined area in the form of an authentication request signal, for example, an LF signal. Send the request signal.

Thereafter, when the LF receiver 126 of the smart-key 120 receives the authentication request signal, the smart-key 120 wakes up. After activation, the smart-key 120 waits for a preset waiting time. That is, the standby time after each smart-key is activated until a certain time is set differently for each of the plurality of smart-keys, and each smart-key waits until its own standby time. Here, the plurality of smart-keys may be three or more. That is, the digital door-lock system of the present invention solves the inconvenience that the execution time of the door-release operation is delayed as the smart-key is used in the past.

Thereafter, the control unit 124 of each smart-key 120 determines whether there is a response signal of another smart-key during its waiting time, and if there is no response signal of another smart-key, The RF transmitter 125 transmits its response signal, for example, a response signal in the form of an RF signal to the door-lock body 100.

For example, among the smart-keys receiving the authentication request signal of the door-lock body 100, the smart-key 120 having the shortest waiting time is recognized that there is no response signal of other smart-keys during its waiting time. And transmits its response signal to the door-lock body 100.

For example, the control unit 124 of the smart-key 120 determines the presence or absence of a response signal of the other smart-key during its waiting time, and other smart-keys other than the smart-key with the shortest waiting time are the standby. By detecting the response signal of the shortest smart-key, it can be switched to the standby mode without transmitting its response signal to the door-lock body.

The presence or absence of a response signal of the other smart-keys may be made through the door-lock body. For example, when the door-lock main body 100 first receives the response signal of the smart-key with the shortest waiting time, the door-lock main body 100 may operate so as not to receive the response signal of the other smart-key thereafter, and the waiting time is the most. The smart-key other than the short-set smart-key may be notified that the response signal has been received.

After that, the control unit 105 of the door-lock main body 100 checks the validity of the response signal received by the RF receiver 108 and when the validity is confirmed, causes the door opening and closing unit 103 to perform a door release operation.

Accordingly, the digital door-lock system of the present invention can increase the convenience by providing a quick door release process to the user and optimize the system by minimizing the power consumption.

2A and 2B are views for explaining a control method of the digital door lock system of the present invention.

2A is a method for authenticating a smart-key which is a portable device in a conventional door-lock system, and FIG. 2B is a method for authenticating a smart-key in a digital door-lock system of the present invention.

As shown in FIG. 2A, in the conventional smart-key authentication method, the door-lock body transmits an authentication request signal to each of the plurality of smart-keys (FOB-1 to FOB-N) sequentially, and accordingly, smart The procedure consists in receiving a response signal for each key. Therefore, the smart-keys that are authenticated in a later order can be authenticated only after waiting for the time of the authentication request signal and response signal of the smart-keys in the previous order. Accordingly, as the number of smart keys increases, the delay time becomes longer, and the door-lock release operation is performed for a long time, which inconveniences the user.

In contrast, as shown in FIG. 2B, the digital door-lock system of the present invention sets different waiting times (W1 to Wn, etc.) for all of the plurality of smart-keys. This waiting time is set to a very short time compared to the authentication request signal and the response signal, so that a plurality of smart-keys can be authenticated in a short time.

Then, when the door-lock body transmits an authentication request signal, a plurality of smart-keys are activated in a predetermined area where the door-lock body can receive the signal, and the waiting time among the activated smart-keys is the most. The short smart-key (FOB-N) determines whether the other smart-key responds after its wait time (Wn) and transmits a response signal to the door-lock body to perform the door release operation in a short time. have.

Looking at an embodiment of such a digital door lock system of the present invention as shown in FIG.

3 is a diagram illustrating an embodiment of a control method of a digital door-lock system according to the present invention.

As shown in FIG. 3, first, the smart-keys in a predetermined area in which the door-lock body transmits an authentication request signal to receive a signal of the door-lock body receive the authentication request signal and wake up function ( It is activated by performing a wake-up function.

After that, each smart-key waits for a preset waiting time, and each smart-key determines the presence or absence of a response signal of another smart-key during its waiting time after its own waiting time. If there is no response signal, the response signal is transmitted to the door-lock body.

That is, in FIG. 3, when the smart-keys having a longer waiting time than the third smart-key FOB-3 and the third smart-key FOB-3 are activated by receiving an authentication request signal of the door-lock body, After the waiting time W2 of the third smart-key (FOB-3) longer than the waiting time of the one smart-key (FOB-1) and the second smart-key (FOB-2), the third smart-key (FOB) -3) determines that there is no response signal of the first smart-key (FOB-1) and the second smart-key (FOB-2) and transmits its response signal to the door-lock body.

Thereafter, the door-lock main body receives the third smart-key (FOB-3) response signal and goes through the procedure of checking whether the response signal is valid and then releases the door-lock when authentication is completed.

Here, if the first smart-key (FOB-1) and the second smart-key (FOB-2) is activated, and the response signal is transmitted to the door-lock body, the third smart-key (FOB-3) is the first The response signal of the smart key (FOB-1) is sensed and the standby mode is switched to the door lock body without transmitting its response signal. Here, the first smart-key FOB-1 may be set to determine whether or not a response signal is transmitted by immediately determining whether or not another smart-key has a response signal.

Looking at the operation sequence of the digital door-lock system of the present invention including the door-lock body 100 and the smart-key 120 as shown in FIG.

4 is a flowchart illustrating an operation process of a digital door-lock system according to an embodiment of the present invention.

As shown in Figure 4, an embodiment of the control method of the digital door-lock system of the present invention is as follows. First, the door-lock body 100 transmits an authentication request signal, for example, an authentication request signal in the form of an LF signal (S402). Here, the door-lock body 100 may receive a door-lock release request input S401 from the user before transmitting the authentication request signal.

That is, when the user wants to release the door, the door-lock body 100 may request the door-lock release, for example, by pressing a button installed on the door-lock body 100 to the door-lock body 100. Door-lock release request can be input (S401). As such, the door-lock main body 100 transmits the authentication request signal only when the user inputs the door-lock release request, thereby minimizing power consumption.

Thereafter, smart-keys in a predetermined area capable of receiving a signal transmitted by the door-lock main body 100, for example, the first smart-key (FOB-1) and the second smart-key (FOB-2) shown in FIG. ) And the third smart-key (FOB-3) receive the authentication request signal of the door-lock body 100 (S412, S422, S432).

Here, when the first smart key (FOB-1), the second smart-key (FOB-2) and the third smart-key (FOB-3) receive the authentication request signal from the door-lock main body 100, All are activated at the same time to perform a wake-up function (S413, S423, S433). That is, the plurality of smart-keys in a predetermined area capable of receiving the signal of the door-lock body 100 are activated at the same time by receiving the authentication request signal.

The first smart-key FOB- 1, the second smart-key FOB- 2 and the third smart-key FOB- 3 thus activated wait for a preset waiting time.

Here, the first smart-key (FOB-1), the second smart-key (FOB-2) and the third smart-key (FOB-3) has a waiting time until a certain point after each smart-key is activated. Each one is set differently. For example, the first smart-key FOB-1 waits for a preset first time, the second smart-key FOB-2 waits for a second time longer than the first time, and the third smart-key (FOB-3) waits for a third time longer than the second time (S414, S424, S434).

Each smart-key determines the presence or absence of a response signal (eg, an RF signal) of another smart-key during its own waiting time (S415, S425, S435). Thereafter, each smart-key transmits a response signal to the door-lock body 100 when there is no response signal of another smart-key.

That is, in FIG. 4, the first smart key FOB-1, the second smart key FOB-2, and the third smart key FOB-3, which have received the authentication request signal from the door-lock main body 100, are received. 1) the first smart-key (FOB-1) waits for the first time (S414), it is determined that there is no response signal of the other smart-keys (S415) and locks its own response signal in the form of an RF signal Transmission to the main body 100 (S416, RF).

On the other hand, the second smart-key (FOB-2) and the third smart-key (FOB-3) waits for the second time and the third time that is its own waiting time (S424, S434). Thereafter, the first smart-key (FOB-1) confirms that the response signal has been transmitted (RF2, RF3) and can be switched to the standby mode without transmitting its response signal to the door-lock body.

As such, the first smart-key (FOB-1) having the shortest waiting time among the plurality of smart-keys receiving the authentication request signal of the door-lock body 100 sends a response signal to the door-lock body 100. By transmitting the door-lock body 100 to quickly recognize the smart-key that can send and receive signals to improve the control speed of the system.

Subsequently, the door lock main body 100 receives a response signal transmitted from the first smart-key FOB-1 having the shortest waiting time (S404). Then, the door-lock body 100 checks the validity of the response signal of the first smart-key (FOB-1) (S405).

The door-lock body 100 releases the door-lock when the validity of the response signal is confirmed and authentication is completed (S407).

As described above, the digital door-lock system according to an embodiment of the present invention includes a plurality of smart-keys, a first smart-key (FOB-1), a second smart-key (FOB-2) and a third smart. -The door-lock release operation can be performed quickly by setting the waiting time of each key (FOB-3) differently.

In other words, the digital door-lock system of the present invention transmits the authentication request signal to all the conventional smart-keys, and sends the authentication request signal directly to the smart-key that wants to release the door lock without going through the process of waiting for a response signal. The transmission simplifies and speeds up the operation of the digital door-lock system. This minimizes power consumption and optimizes the digital door-lock system.

Here, since the waiting time preset for each of the plurality of smart-keys is shorter than the length of the authentication request signal and the response signal, the door release process may be performed more quickly.

Accordingly, the digital door-lock system of the present invention can increase the convenience by providing a quick door release process to the user and optimize the system by minimizing power consumption.

As described above, the digital door-lock system of the present invention can shorten the door release operation time by setting a unique waiting time of each of the plurality of smart-keys. That is, among the smart-keys receiving the authentication request signal transmitted by the door-lock body by presetting a plurality of smart-keys differently in advance after a plurality of smart-keys are activated by receiving a start signal and then a certain time. Smart-key, which has the shortest waiting time, transmits a response signal to the door-lock body, thereby simplifying the door release process, thereby minimizing the operating time of the digital door-lock system.

Accordingly, the digital door-lock system of the present invention can increase the convenience by providing a quick door release process to the user and optimize the system by minimizing power consumption.

As such, the digital door-lock system and its control method of the present invention provide a method for efficiently recognizing a plurality of smart-keys capable of receiving signals of the door-lock body, thereby improving the operation time of the digital door-lock system. It will be considerable that the present invention is included in the present invention regardless of the modifications of the technical idea of the present invention, which are implemented through a method of controlling a plurality of smart-keys by greatly shortening and minimizing power consumption.

As mentioned above, although the invention made by this inventor was demonstrated concretely according to the said Example, this invention is not limited to the said Example and can be variously changed in the range which does not deviate from the summary.
