Door lock control system and method of door lock communication control performed by door lock control system {Door Lock Control System and Method of Door Lock Communication Control Performed by Door Lock Control System}

The present invention relates to a door lock control system and a door lock communication control method performed in the door lock control system. More specifically, when an important event occurs, the deactivated state of the wireless communication unit included in the door lock is changed to the activated state, and the important event is changed to an activated state. According to the event, the information generated by the door lock is transmitted to the server through the activated wireless communication unit, and the information generated by the door lock before the important event occurs is also transmitted to the server, so the wireless communication unit is activated and the wireless communication unit is activated. It relates to a door lock control system and a door lock communication control method performed in the door lock control system that can effectively reduce the power consumption of the door lock generated by communication in the communication unit.

As IoT technology develops, IoT technology is being applied to various products, especially existing products. For example, by combining IoT technology with lighting, the brightness of lighting can be controlled, and the power can be controlled or the amount of power can be checked through an IoT-enabled plug.

One of these examples is a door lock equipped with IoT technology. By applying IoT technology to a door lock that has a general function of opening the door by entering biometric information such as a password or fingerprint, the door lock can communicate with the server, and through this, the user can remotely access the door through a terminal such as a smartphone. You can control the door lock or receive information on events that occur in the door lock, such as entry and exit times and abnormal opening attempts.

However, since the power of the door lock is usually supplied through a battery, power use is limited. Furthermore, when a separate wireless communication module is included in the door lock to communicate with the server, power consumption varies depending on the operation of the wireless communication module. This becomes more. Therefore, various methods are being developed to efficiently use power for door locks equipped with communication functions.

A conventional method to solve the above problem is to periodically turn on/off the wireless communication module of the door lock to reduce power consumption by the wireless communication module. In this method, when the user wants to control the door lock or check the status of the door lock through a smartphone, the door lock must communicate with the server in real time, so the on/off cycle of the wireless communication module cannot be set for a long time. Conversely, if the cycle is set too short, there is a problem that power consumption may increase rather than activating the wireless communication module at all times due to the driving power generated by frequent operation of the wireless communication module.

Meanwhile, in another conventional method, in Korean Patent No. 10-1974500 (“Low-power wireless door lock system”), the door lock includes an activation signal receiver and a wireless transmitting and receiving unit, and the activation signal receiving unit is used to initiate two-way wireless communication. It describes a method of enabling the wireless transceiver to operate and perform wireless communication when a signal is received from an external element (front door camera).

However, in the case of this method, in addition to the wireless transceiver that actually performs communication, an activation signal receiver that performs one-way communication must be additionally provided, which increases the manufacturing cost of the door lock and increases the power consumption of the activation signal receiver that only receives in one direction. Even if this is small, the activation signal receiver must be turned on at all times, so there is a problem of continuous power consumption.

Therefore, there is a need for the development of a new method that can effectively reduce the power consumption of door locks equipped with wireless communication modules.

Figure 3 (A) corresponds to a diagram showing the communication state between the door lock 1000 and the server 2000 when the wireless communication unit 1300 is in an inactive state, and Figure 3 (B) corresponds to a diagram showing the wireless communication unit 1300 ) corresponds to a diagram showing the communication state between the door lock 1000 and the server 2000 when is in the activated state.

In one embodiment of the present invention, as described above, one or more information generated in the door lock 1000 is transmitted to the server 2000 through the wireless communication unit 1300 included in the door lock 1000, or the server 2000 It receives one or more pieces of information being transmitted, and the wireless communication unit 1300 does not always operate, but is usually in an inactive state (sleep), and is in an activated state (wake) when an important event occurs in the door lock 1000. up) and can communicate with the server 2000.

Specifically, when an important event or an event that is not an important event (non-important event) occurs, the door lock 1000 generates information (data #1 to data #N in FIG. 3) corresponding to the non-important event. And the generated information is stored in the memory of the door lock 1000. At this time, as shown in (A) of FIG. 3, the information generated when the wireless communication unit 1300 is in an inactive state is not transmitted to the server 2000 and is simply stored in the memory of the door lock 1000. there is. Even if a plurality of non-important events occur while the wireless communication unit 1300 is in an inactive state, the information according to each non-important event is generated and stored (stacked) and the information is not transmitted to the server 2000. .

Meanwhile, when an important event occurs, the door lock 1000 changes the wireless communication unit 1300 from an inactive state to an activated state and generates information corresponding to the important event, as shown in (B) of FIG. 3. As shown above, the information is transmitted to the server 2000. At this time, when one or more information generated by one or more non-important events that previously occurred is stored in the door lock 1000, the one or more information is also sent to the server 2000 through the wireless communication unit 1300 in an activated state. is sent to In addition, when there is information that the server 2000 wants to transmit to the door lock 1000, the wireless communication unit 1300 in an activated state receives the corresponding information.

As such, in the present invention, when an unimportant event occurs, the information generated in the door lock 1000 is stored, and later, when an important event occurs in the door lock 1000, the wireless communication unit 1300 is activated, Information generated corresponding to important events and previously generated and stored information are transmitted to the server 2000 through the activated wireless communication unit 1300, so that the conventional wireless communication unit 1300 is activated according to a preset cycle. Compared to the method, the activation frequency of the wireless communication unit 1300 is lowered. Therefore, in one embodiment of the present invention, it is possible to reduce the power consumption of the door lock 1000 due to activation of the wireless communication unit 1300 and communication of the activated wireless communication unit 1300.

Hereinafter, steps performed by the door lock 1000 and the server 2000 according to each event that occurs in the door lock 1000 will be described.

Figure 4 schematically shows detailed steps of the external access control step according to an embodiment of the present invention.

As shown in FIG. 4, a door lock control method performed in a door lock control system including a door lock 1000 and a server 2000 that communicates with the door lock 1000, wherein the door lock 1000 includes the door lock. A proximity sensor (1100) that detects an outside visitor from an entrance door (1000) installed; And a wireless communication unit 1300 that wirelessly communicates with the server 2000, wherein the door lock control method includes, by the door lock 1000, proximity within a predetermined distance through the proximity sensor 1100. A first wake-up step of detecting an outside visitor and changing the door lock 1000 from a sleep state to a wake-up state; A first activation step of changing the wireless communication unit 1300 from an inactive state to an activated state as the door lock 1000 changes to a wake-up state; An open determination step of receiving access authentication information from the visitor and determining whether to open the door based on the access authentication information; When the door is determined to be open in the open determination step, the door is unlocked by unlocking the door lock (1000), and the door is locked by the door lock (1000) within a first predetermined time. A first door opening step of generating access information; A first communication step of transmitting the first normal access information to the server 2000 through the activated wireless communication unit 1300 and changing the activated wireless communication unit 1300 to a deactivated state; And a first sleep step of changing the door lock 1000 from the wake-up state to a sleep state; wherein the first communication step changes the wireless communication unit 1300 to an activated state through the first activation step. If there is one or more pieces of information generated by the door lock (1000), the one or more pieces of information can be transmitted to the server (2000).

Specifically, the drawing shown in FIG. 4 schematically shows detailed steps of the external access step performed by the external access control unit 1400 of the door lock 1000. Additionally, in the present invention, the external access step may correspond to the above-described important event.

First, when no event occurs in the door lock 1000 for a predetermined period of time, the door lock 1000 is placed in a sleep state (S10). The door lock 1000 in the sleep state does not stop the operation of all components of the door lock 1000, but the component that detects a trigger to change from the sleep state to the wake-up state always operates. For example, the component may correspond to the proximity sensor 1100, and when the proximity sensor 1100 detects a user outside the door (S11), the door lock 1000 is in a wake-up state from the sleep state. changes to (S12). Step S11 and step S12 may be included in the first wake-up step described above.

In another embodiment of the present invention, the component that detects a trigger to change from a sleep state to a wake-up state may include not only the proximity sensor 1100 but also the keypad unit. Accordingly, when an external user performs an input to activate the keypad unit, the door lock 1000 may change from the sleep state to the wake-up state.

When the door lock 1000 is changed to a wake-up state by the first wake-up step, a first activation step ( Perform S13).

Meanwhile, the door lock 1000 receives access authentication information from a user outside the door, verifies the input authentication information by comparing it with one or more access authentication information stored in the door lock 1000, and verifies the access authentication information. An openness judgment step (S14) is performed to determine whether to open. The access authentication information may correspond to a password, card key information, biometric information, etc.

In another embodiment of the present invention, the first activation step (S13) may be omitted, and when the door lock 1000 changes to the wake-up state through the first wake-up steps (S11 to S12), the first activation step (S13) may be omitted. The wireless communication unit 1300 may change to an activated state. This configuration may be equally applied to the second to fifth activation steps described later.

On the other hand, if the access authentication information input in the opening determination step (S14) is determined to be valid, the door lock 1000, preferably the deadbolt of the door lock 1000, is unlocked to open the door (S15) ), if the door is locked again by the door lock 1000 within a predetermined first time (S16), first normal access information is generated (S17). Steps S15, S16, and S17 may be included in the first door opening step.

More specifically, whether the door is open or locked can be detected by the motion sensor 1200 described above. In addition, the first normal access information may include type information of access authentication information entered by the user such as a password, card key, or biometric authentication information, user identification information, door opening time information, and door locking time information.

Meanwhile, the first door opening step generates door open state information when the door is opened and the door is not locked by the door lock 1000 within a predetermined first time, and the first communication step includes the Door open status information can be transmitted to the server 2000.

Specifically, in step S16 described above, when the door is not locked by the door lock 1000 within a predetermined first time, door open state information is generated (S18). The generated door open state information may include information about the time the door was opened and information about the state in which the door was open for a long time. In this way, the generated door open state information is transmitted to the server 2000 through the activated wireless communication unit 1300, which will be described later, and the server 2000 generates service information based on the received door open state information and finally By transmitting to the user terminal 3000, the user can recognize the situation in which the door is open.

In addition, the door lock control method further includes an access failure information generating step of generating access failure information when the door is determined not to be opened in the opening determination step, and the first communication step includes: When the access failure information is generated through the failure information generation step, the access failure information can be transmitted to the server 2000.

Specifically, if the access authentication information entered by the user in step S14 described above is determined to be invalid, the access failure information generation step is performed. In FIG. 1, it is depicted that the access failure information is generated in step S18, but the access failure information generating step may be performed separately from step S18. Meanwhile, the access failure information may include information about the time when access failed. Likewise, the access failure information is transmitted to the server 2000 through the activated wireless communication unit 1300, which will be described later, and the server 2000 generates service information based on the received access failure information and finally user terminal 3000. ), the user can confirm the record that opening the door failed.

In this way, the first normal access information, door open state information, and access failure information generated in the external access control step can be transmitted to the server 2000 through the wireless communication unit 1300 that has been changed to the activated state.

Specifically, as the wireless communication unit 1300 in the deactivated state is changed to the activated state in step S13, the wireless communication unit 1300 in the activated state performs the step S19 of connecting to the router 4000 described above. At this time, when the wireless communication unit 1300 connects to the router 4000 within the preset connection waiting time, the information generated by performing the first communication step is transmitted to the server 2000 (S20).

In step S20, not only the information generated in the external access control step described above, but also the server ( 2000), and when there is one or more information to be transmitted to the server 2000 to the door lock 1000, the wireless communication unit 1300 in the activated state receives the one or more information from the server 2000. do.

In this way, when communication with the activated wireless communication unit 1300 and the server 2000 is terminated, the first communication step changes the activated wireless communication unit 1300 back to the deactivated state (S21).

Finally, the external access control step ends by performing a first sleep step (S23) in which the door lock 1000, which has been changed to the wake-up state in step S12, is changed back to the sleep state.

Meanwhile, the door lock control method is used when the wireless communication unit 1300, which has been changed to the activated state through the first activation step by the door lock 1000, cannot connect to the preset router 4000 within a predetermined connection waiting time. It further includes a connection error information generation step of generating connection error information, wherein the first normal access information generated through the first door opening step and the connection error information generated through the connection error information generation step are, thereafter, It can be transmitted to the server 2000 through a first communication step performed as the wireless communication unit 1300 is connected to the preset router 4000 within the predetermined connection waiting time. .

Specifically, as the wireless communication unit 1300 in the deactivated state is changed to the activated state in step S13, the wireless communication unit 1300 in the activated state performs the step S19 of connecting to the router 4000 described above. At this time, if connection is not possible within the preset connection waiting time, the connection error information generation step (S22) is performed.

The connection error information generated through the connection error information generation step (S22) may include type information about the connection error, information on the time when the connection error occurred, etc. Meanwhile, since the connection error information generation step (S22) corresponds to a non-critical event and the wireless communication unit 1300 is currently unable to connect to the router 4000, the connection error information is stored in the door lock 1000. , can be transmitted to the server 2000 through the first communication step performed next.

Meanwhile, the server 2000, which has received one or more information from the wireless communication unit 1300 activated through the first communication step (S20, S21), generates one or more service information based on the one or more information and provides the one or more service information. Service information is provided to the user terminal 3000 (S24). Through this, the user can check events occurring in the door lock 1000 on the user terminal 3000.

Figure 5 schematically shows detailed steps of the internal access control step according to an embodiment of the present invention.

As shown in FIG. 5, the door lock 1000 further includes a motion sensor 1200 that senses whether the door is opened according to the control of the door lock 1000, and the door lock control method includes the door lock ( It further includes an internal access control step performed by 1000), wherein the internal access control step detects the movement of the door being opened by the person entering the inside through the motion sensor 1200, and slips. A second wake-up step of changing the door lock 1000 from the state to the wake-up state; A second activation step of changing the wireless communication unit 1300 from a deactivated state to an activated state as the door lock 1000 changes to a wake-up state; When the door is opened by an inside person, it is determined whether the deadbolt provided in the door lock 1000 has been inserted into the door lock 1000, and whether the deadbolt has been inserted into the door lock 1000 is determined. an internal access determination step of generating second normal access information when it is determined that the deadbolt has not been inserted into the door lock (1000) and generating intrusion information; A second communication step of transmitting the second normal access information or the intrusion information to the server 2000 through the wireless communication unit 1300 in the activated state and changing the wireless communication unit 1300 in the activated state to a deactivated state. ; And a second sleep step of changing the door lock 1000 from the wake-up state to a sleep state; wherein the second communication step changes the wireless communication unit 1300 to an activated state through the second activation step. If there is one or more pieces of information generated by the door lock (1000), the one or more pieces of information can be transmitted to the server (2000).

Specifically, when no event occurs in the door lock 1000 for a predetermined period of time, the door lock 1000 is placed in a sleep state (S30). The door lock 1000 in the sleep state does not stop the operation of all components of the door lock 1000, but the component that detects a trigger to change from the sleep state to the wake-up state always operates. For example, the corresponding component may correspond to the motion sensor 1200, and when the motion sensor 1200 detects that the door lock 1000 is unlocked by the user inside the door and the door is opened (S31) The door lock 1000 changes from the sleep state to the wake-up state (S32). Step S31 and step S32 may be included in the second wake-up step described above.

In another embodiment of the present invention, components that detect a trigger for changing from the second wake-up stage to the wake-up state include not only the motion sensor 1200, but also the door lock 1000 exposed toward the inside of the door. A component that is provided on two sides and applies force when the user wants to open the door may also be included. For example, the above components may include a push handle or switch, and the user inside opens the door by pushing the push handle of the door lock (1000) or opens the door by manipulating the switch of the door lock (1000). When opening, the door lock 1000 may change from a sleep state to a wake-up state.

When the door lock 1000 is changed to a wake-up state by the second wake-up step, a second activation step ( Perform S33).

Meanwhile, the door lock 1000 that has been changed to the wake-up state performs an internal access determination step. The interior access determination step first determines whether the deadbolt included in the mortise of the door lock 1000 has entered the interior of the door lock 1000 when the door is opened (S34). If it is determined in step S34 that the deadbolt has been inserted into the door lock 1000, the door is normally opened, and second normal access information is generated (S35). On the other hand, if it is determined in step S34 that the deadbolt has not been inserted into the door lock 1000, the door lock 1000 is damaged by an external impact, etc. and the door is opened, and intrusion information is generated (S36).

In this way, the second normal access information and intrusion information generated through the internal access control step can be transmitted to the server 2000 through the wireless communication unit 1300 that has been changed to the activated state.

Specifically, as the wireless communication unit 1300 in an inactive state is changed to an activated state in step S33, the wireless communication unit 1300 in an activated state performs a step (S37) of connecting to the router 4000. At this time, when the wireless communication unit 1300 connects to the router 4000 within the preset connection waiting time, the information generated by performing the second communication step is transmitted to the server 2000 (S38). Meanwhile, in step S37, if the wireless communication unit 1300 fails to connect within the preset connection waiting time, step S40 is performed to generate connection error information, and the steps after step S40 shown in FIG. 5 are shown in FIG. 4. Since it has been described above, it will be omitted.

In step S38, not only the information generated in the above-described internal access control step, but also the server ( 2000), and when there is one or more information to be transmitted to the server 2000 to the door lock 1000, the wireless communication unit 1300 in the activated state receives the one or more information from the server 2000. do.

In this way, when communication with the activated wireless communication unit 1300 and the server 2000 is terminated, the second communication step changes the activated wireless communication unit 1300 back to the deactivated state (S39).

Finally, the interior access step ends by performing a second sleep step (S41) in which the door lock 1000, which has been changed to the wake-up state in step S32, is changed back to the sleep state.

Meanwhile, the server 2000, which has received one or more information from the wireless communication unit 1300 activated through the second communication step (S38, S39), generates one or more service information based on the one or more information and provides the one or more service information. Service information is provided to the user terminal 3000 (S42). Through this, the user can check events occurring in the door lock 1000 on the user terminal 3000.

As shown in FIG. 5, the internal access control step corresponds to an important event, and the second normal access information and intrusion information generated through the internal access control step are immediately transmitted to the server 2000 through the activated wireless communication unit 1300. It was explained that it was transmitted to

In another embodiment of the present invention, the normal opening of the door in the internal access control step corresponds to an unimportant event, and therefore the second normal access information generated through the internal access control step is stored in the door lock 1000 and later It can be transmitted to the server 2000 through communication between the wireless communication unit 1300 and the server 2000 performed in response to an important event that occurs. At this time, the wireless communication unit 1300, which has been changed to the activated state in step S33, may be changed to the deactivated state when the second normal access information is generated.

In another embodiment of the present invention, the event in which intrusion information is generated in step S36 corresponds to an important event, and if the wireless communication unit 1300 fails to connect within the preset connection waiting time in step S37, the wireless communication unit 1300 ) repeats attempts to connect to the router 4000, and immediately transmits the intrusion information generated when the wireless communication unit 1300 connects to the router 4000 to the server 2000 according to the connection attempt. You may.

Figure 6 schematically shows detailed steps of the abnormal control step according to an embodiment of the present invention.

As shown in FIG. 6, the door lock control method further includes an abnormal control step performed by the door lock 1000, and the abnormal control step is performed by detecting an abnormal state of the door lock 1000. A third wake-up step of changing the door lock 1000 from the state to the wake-up state; A third activation step of changing the wireless communication unit 1300 from a deactivated state to an activated state as the door lock 1000 changes to a wake-up state; An abnormal information generation step of generating abnormal information including type information and occurrence time information of the abnormal state of the door lock 1000; A third communication step of transmitting the abnormal information to the server 2000 through the activated wireless communication unit 1300 and changing the activated wireless communication unit 1300 to a deactivated state; And a third sleep step of changing the door lock 1000 from the wake-up state to a sleep state; wherein the third communication step changes the wireless communication unit 1300 to an activated state through the third activation step. If there is one or more pieces of information generated by the door lock (1000), the one or more pieces of information can be transmitted to the server (2000).

Specifically, the drawing shown in FIG. 6 schematically shows detailed steps of the abnormal control step performed by the abnormal control unit 1600 of the door lock 1000. Additionally, in the present invention, the abnormal control step may correspond to the above-described important event.

First, when no event occurs in the door lock 1000 for a predetermined period of time, the door lock 1000 is placed in a sleep state (S50). The door lock 1000 in the sleep state does not stop the operation of all components of the door lock 1000, but the component that detects a trigger to change from the sleep state to the wake-up state always operates. For example, the component may correspond to a state detection unit (not shown) for detecting an abnormal state of the door lock 1000, and the state detection unit (not shown) detects an abnormal state of the door lock 1000. When detected (S51), the door lock 1000 changes from the sleep state to the wake-up state (S52). Step S51 and step S52 may be included in the third wake-up step described above.

In the present invention, the abnormal state is a state in which the remaining battery power of the door lock 1000 is low, a strong external shock is applied to the door lock 1000, a fire occurs in the door lock 1000, and the state in which the door lock 1000 is damaged. It may include a state in which an error occurred in the operation of , and the state detection unit (not shown) can detect these states of the door lock 1000.

When the door lock 1000 is changed to a wake-up state by the third wake-up step, a third activation step ( Perform S53).

Meanwhile, the abnormality control step performs an abnormal information generation step (S54) that generates abnormal information for the detected abnormal state. Specifically, the abnormal information includes type information of the abnormal state and information on the time of occurrence when the abnormal state is detected. In this way, the abnormal information generated through the abnormal control step can be transmitted to the server 2000 through the wireless communication unit 1300 that has been changed to the activated state.

Specifically, as the wireless communication unit 1300 in an inactive state is changed to an activated state in step S53, the wireless communication unit 1300 in an activated state performs a step (S55) of connecting to the router 4000. At this time, when the wireless communication unit 1300 connects to the router 4000 within the preset connection waiting time, the third communication step is performed and the generated information is transmitted to the server 2000 (S56). Meanwhile, in step S55, if the wireless communication unit 1300 fails to connect within the preset connection waiting time, step S58 is performed to generate connection error information, and the steps after step S58 shown in FIG. 6 are shown in FIG. 4. Since it has been described above, it will be omitted.

In step S56, not only the information generated in the above-described abnormal control step, but also the stored information in the case where information generated in the door lock 1000 before the abnormal control step is performed is stored in the server 2000. is transmitted, and when there is one or more information to be transmitted to the server 2000 to the door lock 1000, the wireless communication unit 1300 in the activated state receives the one or more information from the server 2000.

In this way, when communication with the activated wireless communication unit 1300 and the server 2000 is terminated, the third communication step changes the activated wireless communication unit 1300 back to the deactivated state (S57).

Finally, the abnormal control step ends the abnormal control step by performing a third sleep step (S59) in which the door lock 1000, which has changed to the wake-up state in step S52, is changed back to the sleep state.

Meanwhile, the server 2000, which has received one or more information from the wireless communication unit 1300 activated through the third communication step (S56, S57), generates one or more service information based on the one or more information and provides the one or more service information. Service information is provided to the user terminal 3000 (S60). Through this, the user can check events occurring in the door lock 1000 on the user terminal 3000.

Figure 7 schematically shows detailed steps of the remote control step according to an embodiment of the present invention.

As shown in Figure 7, the door lock control method further includes a remote control step; the remote control step is a user terminal 3000 that communicates with the server 2000 by the server 2000. ) receiving a request to unlock the door lock 1000, and generating first control information to unlock the door lock 1000 based on the request; If the door lock 1000 is not unlocked by the first control information within a predetermined second time period, the server 2000 cancels the unlocking of the door lock 1000 by the first control information. , a first control information cancellation step of transmitting a cancellation result to the user terminal 3000; A fourth wake-up step in which the door lock 1000 detects an outsider approaching within a predetermined distance through the proximity sensor 1100 and changes the sleep state of the door lock 1000 to a wake-up state; A fourth activation step of changing the wireless communication unit 1300, which is deactivated, to an activated state as the door lock 1000 is changed to a wake-up state by the door lock 1000; First control information that receives the first control information from the server 2000 through the wireless communication unit 1300 in the activated state when a preset input is received from the external visitor by the door lock 1000 Receiving stage; By the door lock 1000, the door lock 1000 is unlocked based on the first control information received from the server 2000 to open the door, and the door is opened within a predetermined third time by the door lock 1000. ) A second door opening step of generating second normal access information when locked by ); By the door lock 1000, the second normal access information is transmitted to the server 2000 through the wireless communication unit 1300 in the activated state, and the wireless communication unit 1300 in the activated state is changed to a deactivated state. Fourth communication stage; And a fourth sleep step of changing the door lock 1000 from the wake-up state to a sleep state by the door lock 1000, wherein the fourth communication step includes the wireless communication unit through the fourth activation step. If there is one or more information generated by the door lock 1000 before 1300 is changed to the activated state, the one or more pieces of information can be transmitted to the server 2000.

In FIGS. 4 to 6 described above, events that occur in the door lock 1000 itself according to the user's approach and input for opening the door are explained, and in FIGS. 7 and 8 described later, the user uses the user terminal 3000. Let us explain the events that occur in the server 2000 and the door lock 1000 according to the input for remotely controlling the door lock 1000.

As shown in Figure 7, the remote control step allows the user to unlock the door lock 1000 without entering separate unique information such as a password or card key on the door lock 1000 through the user terminal 3000. It corresponds to an event that allows.

Specifically, the server 2000 receives a request to unlock the door lock 1000 from the user terminal 3000 (S70). The request corresponds to request information for unlocking a specific door lock 1000 that can be controlled by the user terminal 3000, and the specific door lock 1000 is registered in the process of registering the user terminal 3000 on the server 2000. It may be preset. Meanwhile, the server 2000 generates first control information that can unlock the door lock 1000 based on the request received from the user terminal 3000 (S71). The steps S70 and S71 described above may be included in the first control information generation step. The first control information generated through the first control information generation step is not immediately transmitted to the door lock 1000, but when the wireless communication unit 1300 is activated according to a specific condition in the door lock 1000, the door lock ( 1000).

After the server 2000 generates the first control information through the first control information control step, whether the first control information is transmitted to the door lock 1000 within a predetermined second time ('5 minutes' in FIG. 7). (S72), and in step S72, if the first control information is not transmitted to the door lock 1000 within the predetermined second time, the generated first control information is canceled, and the cancellation result is reported to the user. Transmit to terminal 3000 (S73). The above-described step S73 corresponds to the first control information cancellation step.

As such, in the present invention, by setting the second time corresponding to the time limit for transmitting the first control information to the door lock 1000, the door lock 1000 is maintained even after the first control information is generated and sufficient time has passed. It can be prevented from being unlocked even if the user does not enter the password into the door lock 1000 at an unwanted time.

Meanwhile, in step S72, when the external access control step or the internal access control step described above is performed within the predetermined second time (S74), the user directly controls the door lock 1000 to open the door, and the server ( 2000), the first control information is not transmitted to the door lock 1000, but when the external access control step or the internal access control step is terminated, the similarly generated first control information is canceled, and the cancellation result is It is transmitted to the user terminal 3000 (S75).

The above-described first control information generation step and first control information cancellation step may be performed in the second remote control unit 2100 included in the server 2000.

Although not shown in FIG. 7, when no event occurs in the door lock 1000 for a predetermined period of time, the door lock 1000 is placed in a sleep state. Afterwards, when the proximity sensor 1100 provided in the door lock 1000 detects an outside user from the door (S76), the door lock 1000 changes from the sleep state to the wake-up state (S77). Step S76 and step S77 may be included in the fourth wakeup step described above.

A fourth activation step ( Perform S78).

Meanwhile, after the door lock 1000 is changed to the wake-up state, it is determined whether an input for unlocking is received based on the first control information within a predetermined time (S79), and if the input is not received within a predetermined time, If not, the wireless communication unit 1300 in the activated state is changed back to the deactivated state (S80), and the door lock 1000 in the wake-up state is also converted back to the sleep state (S81).

On the other hand, in step S79, when the user outside the door receives an input (in FIG. 7, pressing the '*' button on the keypad for 5 seconds) to unlock the door lock 1000 based on the first control information within a predetermined time ( In S82), the door lock 1000 receives the first control information from the server 2000 through the wireless communication unit 1300 in an activated state (S85). Step S82 and step S85 may be included in the first control information reception step described above.

In another embodiment of the present invention, as shown in FIG. 7, the wireless communication unit 1300 changed to the activated state performs the step (S83) of connecting to the router 4000 described above. At this time, when the wireless communication unit 1300 connects to the router 4000 within the preset connection waiting time, first control information can be received from the server 2000 (S84), and the wireless communication unit 1300 is connected to the router 4000. If the connection is not made within the set connection waiting time, step S90 of generating connection error information is performed. The steps after step S90 shown in FIG. 7 are described in detail in FIG. 4 and will be omitted.

Meanwhile, the door lock 1000, which has received the first control information from the server 2000 through the first control information reception step, does not receive a registered password, card key, or biometric information from the user, but according to the first control information. Unlock and open the door (S85). At this time, when the opened door is locked again by the door lock 1000 within a third predetermined time (S86), second normal access information is generated (S87). The steps S85, S86, and S87 may be included in the second door opening step, and the second normal access information includes information identifying that the door has been opened by remote control, user identification information, door opening time information, and door locking. It may include visual information, etc.

Meanwhile, in the above-described step S86, when the door is not locked by the door lock 1000 within a predetermined third time, door open state information is generated (S88). The generated door open state information may include information about the time the door was opened and information about the state in which the door was open for a long time. In this way, the generated door open state information is transmitted to the server 2000 through the activated wireless communication unit 1300, which will be described later, and the server 2000 generates service information based on the received door open state information and finally By transmitting to the user terminal 3000, the user can recognize the situation in which the door is open.

In this way, the second normal access information or door open state information generated in the remote control step can be transmitted to the server 2000 through the wireless communication unit 1300 that has been changed to the activated state.

Specifically, as the wireless communication unit 1300 in the deactivated state is changed to the activated state in step S78, the wireless communication unit 1300 in the activated state performs the step S83 of connecting to the router 4000 described above. At this time, when the wireless communication unit 1300 connects to the router 4000 within the preset connection waiting time, the fourth communication step is performed to transmit the information generated by the door lock 1000 to the server 2000 (S89) .

In step S89, not only the information generated in the remote control step, but also, if information generated in the door lock 1000 before the remote control step is performed, the stored information is also transmitted to the server 2000. And, when the server 2000 has one or more information to be transmitted to the door lock 1000, the wireless communication unit 1300 in the activated state receives the one or more information from the server 2000.

In this way, when communication with the activated wireless communication unit 1300 and the server 2000 is terminated, the fourth communication step changes the activated wireless communication unit 1300 back to the deactivated state (S91).

Finally, the remote control step ends the remote control step by performing a fourth sleep step (S92) in which the door lock 1000, which has been changed to the wake-up state in step S77, is changed back to the sleep state.

In this way, the above-described fourth wake-up step, fourth activation step, first control information reception step, second door opening step, fourth communication step, and fourth sleep step are performed by the first remote control unit included in the door lock 1000. (1700).

Meanwhile, the server 2000, which has received one or more information from the wireless communication unit 1300 activated through the fourth communication step (S89, S91), generates one or more service information based on the one or more information and provides the one or more service information. Service information is provided to the user terminal 3000 (S93). Through this, the user can check events occurring in the door lock 1000 through the user terminal 3000.

Figure 8 schematically shows detailed steps of the one-time password control step according to an embodiment of the present invention.

As shown in Figure 8, the door lock control method further includes a one-time password control step; the one-time password control step is a user terminal that communicates with the server 2000 by the server 2000. Receives a request for issuance of a one-time password from (3000), and generates a one-time password for unlocking the door lock 1000 based on the request and second control information for unlocking the door lock 1000 by the one-time password. One-time password creation step; If the door lock 1000 is not unlocked by receiving the one-time password within the validity period of the one-time password by the server 2000, the unlocking of the door lock 1000 is canceled by the second control information, A second control information cancellation step of transmitting a cancellation result to the user terminal 3000; A fifth wake-up step of changing the door lock 1000 from a sleep state to a wake-up state by detecting an outsider approaching within a predetermined distance by the door lock 1000 through the proximity sensor 1100; By the door lock 1000, as the door lock 1000 is changed to a wake-up state, the wireless communication unit 1300, which is inactive, is changed to an activated state, and the server 2000 is activated through the wireless communication unit 1300. A fifth activation step of receiving the second control information from; By the door lock 1000, when the one-time password is input from the outside visitor, the input one-time password is verified based on the second control information, and when verified to be valid, the door lock 1000 A third door opening step of unlocking and opening the door; A third normal access information generating step of generating third normal access information when the door is locked by the door lock 1000 within a predetermined fourth time after the door is opened through the third door opening step; A fifth communication step of transmitting the third normal access information to the server 2000 through the activated wireless communication unit 1300 and changing the activated wireless communication unit 1300 to a deactivated state; And a fifth sleep step of changing the door lock 1000 from the wake-up state to a sleep state; wherein the fifth communication step changes the wireless communication unit 1300 to an activated state through the fifth activation step. If there is one or more pieces of information generated by the door lock (1000), the one or more pieces of information can be transmitted to the server (2000).

As shown in Figure 8, in the one-time password control step, the user receives a one-time password from the server 2000 through the user terminal 3000 and inputs the issued one-time password into the door lock 1000. This corresponds to an event that allows you to unlock .

Specifically, the server 2000 receives a request from the user terminal 3000 to issue a one-time password that can unlock the door lock 1000 (S100). The request corresponds to information requesting the issuance of a one-time password to unlock a specific door lock 1000 that can be controlled by the user terminal 3000, and the specific door lock 1000 is sent to the server 2000 by the user terminal 3000. ) may be preset during registration. Meanwhile, the server 2000 generates a one-time password and second control information that can unlock the door lock 1000 using the one-time password based on the request received from the user terminal 3000 (S101). Step S100 and step S101 may be included in the one-time password generation step. The one-time password generated through the one-time password generation step is provided to the user terminal 3000, and the second control information is not immediately transmitted to the door lock 1000, but is transmitted to the wireless communication unit according to certain conditions in the door lock 1000. When 1300 is activated, it may be transmitted to the door lock 1000.

After generating a one-time password and second control information through the one-time password generation step in the server 2000, it is determined whether the door lock 1000 has been unlocked through the one-time password within a predetermined validity period (S102), and if within the validity period If the generated one-time password is not used, the generated one-time password and the second control information are canceled, and the cancellation result is transmitted to the user terminal 3000 (S103). The step S103 corresponds to the second control information cancellation step. As such, in the present invention, by setting an expiration date for using the one-time password, it is possible to prevent the door lock 1000 from being unlocked by the one-time password and the second control information after a sufficient period of time has passed since the one-time password is issued. You can.

The above-described one-time password generation step and second control information cancellation step may be performed by the second one-time password control unit 2200 included in the server 2000.

Meanwhile, the one-time password control step receives the second control information from the server 2000 through the fifth activation step and after the one-time password and the second control information are generated through the one-time password generation step. When the first communication step is performed at a time before the following, the door lock 1000 may receive the second control information in advance from the server 2000 through the first communication step.

Specifically, when the external access control step or the internal access control step described above is performed within the validity period of the one-time password generated in step S102 (S104), the external access control step or the internal access control step is performed by the wireless communication unit 1300. Since it includes detailed steps of activating and communicating with the server 2000, the second control information generated from the server 2000 can be received in advance in the external access control step or the internal access control step ( S105). That is, since the second control information is received in the process of communicating with the server 2000 in the external access control step or the internal access control step, separate communication for receiving only the second control information can be omitted, and therefore, This can have the effect of reducing the power consumption of the door lock (1000).

Afterwards, access is made through the external access control step or the internal access control step described above (S107), and the door lock 1000 is not unlocked by the second control information previously received in step S105 within the validity period of the one-time password. In case S106, the cancellation result is transmitted to the user terminal 3000 as in step S103 described above.

Although not shown in FIG. 8, when no event occurs in the door lock 1000 for a predetermined period of time, the door lock 1000 is placed in a sleep state. Afterwards, when the proximity sensor 1100 provided in the door lock 1000 detects an outside user from the door through the fifth wake-up step (S108), the door lock 1000 changes from the sleep state to the wake-up state. do.

A fifth activation step ( Perform S109).

Meanwhile, after the door lock 1000 is changed to the wake-up state, it is determined whether a trigger input for entering a one-time password is received within a predetermined time (S110), and if the trigger input is not received within a predetermined time, In this case, the wireless communication unit 1300 in the activated state is changed back to the deactivated state (S112), and the door lock 1000 in the wake-up state is also switched back to the sleep state (S113). Here, the trigger input may correspond to an input for entering a mode for receiving and unlocking a one-time password.

On the other hand, in step S110, a trigger input for unlocking the door lock 1000 with a one-time password is received from a user outside the door within a predetermined time (in FIG. 8, the '*' button on the keypad is input twice), and the one-time password is received. When received (S111), the door lock 1000 receives the second control information from the server 2000 through the wireless communication unit 1300 in an activated state through the fifth activation step (S115). If step S105 is performed as described above, step S115 may be omitted.

In another embodiment of the present invention, as shown in FIG. 8, the wireless communication unit 1300 changed to the activated state performs the step (S114) of connecting to the router 4000 described above. At this time, when the wireless communication unit 1300 connects to the router 4000 within the preset connection waiting time, second control information can be received from the server 2000 (S115), and the wireless communication unit 1300 is connected to the router 4000. If connection is not possible within the set connection waiting time, connection error information is generated (S122), and the steps after step S122 shown in FIG. 8 are omitted as they are described in detail in FIG. 4.

Meanwhile, the door lock 1000 verifies the one-time password entered by the user based on the second control information received from the server 2000 through the third door opening step (S116), and verifies that the one-time password is valid. In this case, unlock and open the door (S117). If it is verified in step S116 that the one-time password is invalid, inconsistent information is generated (S120). The discrepancy information may include information about the history of receiving an incorrect one-time password and information on the reception time of the one-time password. Step S116, step S117, and step S120 may be included in the third door opening step.

Subsequently, the third normal access information generation step (S119) generates the third normal access information when the door opened in step S117 is locked again by the door lock 1000 within a predetermined fourth time (S118). The third normal access information may include information identifying that the door has been opened using a one-time password, user identification information, door opening time information, and door locking time information.

On the other hand, if the door is not locked by the door lock 1000 within the fourth predetermined time in step S118 described above, door open state information is generated (S121). The generated door open state information may include information about the time the door was opened and information about the state in which the door was open for a long time. In this way, the generated door open state information is transmitted to the server 2000 through the activated wireless communication unit 1300, which will be described later, and the server 2000 generates service information based on the received door open state information and finally By transmitting to the user terminal 3000, the user can recognize the situation in which the door is open.

In this way, the third normal access information, door open state information, or mismatch information generated in the one-time password control step may be transmitted to the server 2000 through the wireless communication unit 1300 changed to the activated state.

Specifically, as the wireless communication unit 1300 in the deactivated state is changed to the activated state in step S109, the wireless communication unit 1300 in the activated state performs the step S114 of connecting to the router 4000 described above. At this time, when the wireless communication unit 1300 connects to the router 4000 within the preset connection waiting time, the information generated by the door lock 1000 is transmitted to the server 2000 through the fifth communication step performed by the door lock. (S123).

In step S123, not only the information generated in the one-time password control step, but also the information generated in the door lock 1000 before the one-time password control step is stored, the stored information is also sent to the server 2000. When there is one or more information to be transmitted from the server 2000 to the door lock 1000, the activated wireless communication unit 1300 receives the one or more pieces of information from the server 2000.

In this way, when communication with the activated wireless communication unit 1300 and the server 2000 is terminated, the fifth communication step changes the activated wireless communication unit 1300 back to the deactivated state (S124).

Finally, the one-time password control step ends by performing a fifth sleep step (S125) in which the door lock 1000, which has been changed to the wake-up state, is changed back to the sleep state.

In this way, the above-described 5th wake-up step, 5th activation step, 3rd door opening step, 3rd normal access information generation step, 5th communication step, and 5th sleep step are the first disposable device included in the door lock 1000. It can be performed by the password control unit 1800.

Meanwhile, the server 2000, which has received one or more information from the wireless communication unit 1300 activated through the fifth communication step (S123, S124), generates one or more service information based on the one or more information and provides the one or more service information. Service information is provided to the user terminal 3000 (S126). Through this, the user can check events occurring in the door lock 1000 through the user terminal 3000.

In another embodiment of the present invention, the wireless communication unit 1300 and the server 2000 in an activated state in the first to fifth communication stages transmit and receive one or more generated information, and also transmit the time of the door lock 1000 to the server. (2000)'s time synchronization process can also be performed.

In another embodiment of the present invention, the door lock 1000 may not include the proximity sensor 1100. Accordingly, when the door lock 1000 does not have a proximity sensor 1100, the door lock 1000 in the sleep state changes to a wake-up state as the proximity sensor 1100 detects an outside user in each of the above-mentioned events. The configuration can be implemented in different ways. For example, as the user activates the keypad portion of the door lock 1000, the door lock 1000 in the sleep state may be changed to a wake-up state, and as the user touches the door lock 1000 with an authentication means such as a card key. The door lock 1000 in the sleep state may be changed to the wake-up state.
