The program storage unit 230 is connected to the microprocessor 250 and is a part in which various programs for operating the remote control key 200 are embedded. The memory portion of the program storage unit 230 may use EEPROM or flash memory so that recorded data is not erased even when there is no power supply.

The power supply unit 240 serves to supply power for the operation of each component of the remote control key 200 including the microprocessor 250. The power supply unit 240 supplies power to each component of the remote control key 200 through the battery. For example, a battery can be used by connecting two lithium batteries in parallel so as to supply power for a long time, or can use a regular battery and can be configured in various ways.

The low voltage detection unit 260 may cause a problem that the remote controller key 200 does not operate because the voltage of the battery falls below a predetermined voltage, and serves to detect whether the voltage of the battery is below a predetermined voltage. The low voltage detection unit 260 is composed of a voltage detection means for detecting the current voltage of the battery and a comparison means for determining that the battery is a low voltage by comparing the detected voltage with a predetermined reference voltage.

The melody generator 270 serves to generate an alarm sound under the control of the microprocessor 250 when the low voltage detection signal of the low voltage detector 260 is sent to the microprocessor 250. The generation of sound in the melody generator 270 may be implemented by a buzzer. As such, it is necessary to allow the user to know that the remote control key 200 is low voltage so as to take appropriate measures (eg, battery replacement, etc.).

The switch unit 280 is located on one surface of the remote control key 200 to serve to turn on / off the power of the remote control key 200. The user can extend the period of use of the remote control key 200 by reducing the power consumption by turning off the switch when there is no use of the remote control key 200 for a long time, such as a long trip. The switch unit 200 may be an on / off switch or a tact switch that is relatively easy to operate.

According to another embodiment of the present invention, the ID registration start code may not be used. Thus, the registration ID storage unit 220 does not store the ID registration start code, only the registration ID. In the wireless transmitter 210, the ID registration start code is not transmitted, and only the registration ID is transmitted. In this case, when the switch unit 280 is switched from the off state to the on state of the wireless transmitter 210 of the remote control key 200, the initial ID registration start code is not transmitted and the registration ID is periodically transmitted.

In another exemplary embodiment, even when the remote controller key 200 is turned on, the interval between the steps (g) and (h), that is, the interval where the ID registration start code is transmitted, does not appear.

In this case, the registration is stored in the registration ID input storage unit 130 under the control of the microprocessor 150 when the registration ID comes with a code suitable for registration in the door lock 100. In addition, since the periodic registration ID is transmitted from the remote control key 200, if the registration ID of the remote control key 200 is already stored in the registration ID input storage unit 130 of the door lock 100, The microprocessor 150 controls this so that it is not stored.

After step (o), the wireless receiver 110 receives a reception waiting command and waits for a predetermined time.

In step (p), the infrared projection from the infrared transmitting unit 122 ends. At this point, the infrared receiver 124 continues to receive infrared rays reflected from the human body, and the wireless receiver 110 continues to receive.

In step (q), the infrared reception by the infrared receiver 124 ends. At this point, the wireless receiver 110 continues to receive.

The interval between steps (p) and (q) is a time delay period from the time when the infrared projection by the infrared transmitter 122 ends to the time when the infrared reception by the infrared receiver 124 ends.

In the step (r), when the wireless receiver 110 waits for reception and the registration ID signal of the remote controller key 200 is not input to the microprocessor 150 for a predetermined time (for example, 3 seconds). At this point, the wireless receiver 110 is put into a sleep state under the control of the microprocessor 150.

In the section between step (q) and step (r), the wireless receiver 110 is operating, but the infrared transmitter 122 and the infrared receiver 124 are not operated.

In step (s), it is time to start infrared projection through the infrared transmitter 122 again.

The interval between step (r) and step (s) is a time zone study from the time when the wireless receiver 110 changes to the sleep state under the control of the microprocessor 150 until the infrared transmitter 122 projects the infrared light again. to be. As such, the infrared transmitter 122 may be operated again when the wireless receiver 110 changes to a sleep state after a predetermined time, thereby reducing power loss of the door lock 100.

Thereafter, the infrared transmitter 122 projects the infrared rays at regular intervals, and the infrared receiver 124 receives the infrared rays reflected from the human body. Under the control of the microprocessor 150 receiving the human body detection signal by the infrared receiver 124, the wireless receiver 110 of the door lock 100 is registered from the wireless transmitter 210 of the remote control key 200 for a predetermined time. It is in a waiting state for whether there is an ID transmission. If there is no registration ID transmission from the wireless transmitter 210 of the remote control key 200 even after a certain time, the wireless receiver 110 of the door lock 100 stops the operation and returns to the sleep state.

Here, the description of the case where the wireless receiving unit 110 of the door lock 100 does not receive the registration ID of the remote control key 200 so that a predetermined time elapses, or in the following FIG. 8, the door lock before the predetermined time elapses A case in which the wireless receiving unit 110 of 100 receives the registration ID of the remote control key 200 will be described.

FIG. 8 is a time chart illustrating a lock release / correction process by an infrared ray sensing unit according to an embodiment of the present invention.

In the step (a '), the infrared transmitter 122 starts to project one cycle infrared light. Since the remote control key 200 is in the on state before step (a '), it is assumed that before the step (a'), the wireless transmitter 210 transmits the registration ID of the remote control key 200 to the outside at regular intervals.

As an embodiment of the present invention as described above, if the remote control key 200 is not turned on in the lock device release process of the door lock 100, the registration ID of the remote control key 200 cannot be transmitted to the outside of the door lock 100. The lock release of the lock will not be made.

The infrared transmitter 122 of the door lock 100 projects infrared rays at regular intervals. Herein, the registration ID transmission period in the wireless transmitter 210 and the infrared transmission period in the infrared transmitter 122 may be inconsistent with each other.

In the step (b '), the infrared transmitter 122 projects infrared rays, but the infrared rays reflected from the human body are not received by the infrared receiver 124, and the wireless transmitter 210 of the remote control key 200 performs one cycle. It is time to start sending the registration ID.

In the step (c '), the infrared rays projected by the infrared transmitter 122 are reflected by the human body, and the infrared rays are detected by the infrared receiver 124. However, the wireless receiver 110 of the door lock 100 is not operating in the reception standby state.

In one embodiment of the present invention, the registration ID transmission time in the wireless transmitter 210 of the remote control key 200 is between (a ') and (c') step, but this is arbitrary. For example, the time point may be before step (a ') or after step (c'), and may be the same point as step (a ') or the same point as step (c').

In step (d '), the wireless receiver 110 of the door lock 100 wakes up and changes to a reception standby state. From this point in time, the wireless receiver 110 of the door lock 100 receives the registration ID transmitted from the wireless transmitter 210 of the remote control key 200. The registration ID is received here but not the complete registration ID.

In the step (e '), it is the time point at which the one-cycle infrared projection from the infrared transmitter 122 ends. At this point, the infrared receiver 124 is receiving infrared rays reflected from the human body, and the wireless receiver 110 of the door lock 100 is in a standby state to be transmitted from the wireless transmitter 210 of the remote control key 200. The registration ID is being received.

In step (f '), the infrared reception of the infrared receiver 124 ends. At this point, the wireless reception unit 110 is in a reception standby state, and receives the registration ID transmitted from the wireless transmission unit 210 of the remote control key 200.

In step (g '), it is time to end the one-cycle registration ID transmission from the wireless transmitter 210 of the remote control key 200. At this point, the wireless receiver 110 of the door lock 100 is in a standby state for reception.

Here, the registration ID of the remote control key 200 is partially received through the wireless receiving unit 110, but not a complete registration ID. As a result, the lock release by the control of the microprocessor 150 is not made. The release of the locking device of the door lock 100 corresponds to a registration ID transmitted from the wireless transmitter 210 of the remote control key 200 and a registration ID stored in the registration ID input storage 130 of the door lock 100 in advance. Only if that happens.

In step (h '), it is time to start the one-cycle registration ID transmission from the wireless transmitter 210 again. At this point, the wireless receiver 110 of the door lock 100 is in a standby state for reception.

In step (i '), it is the time point when the one-cycle registration ID transmission from the wireless transmitter 210 ends. At this point, the wireless receiver 110 of the door lock 100 is in a standby state for reception.

In the step (j '), the reception standby state of the wireless receiver 110 of the door lock 100 changes to the sleep mode.

The interval between step (i ') and (j') is the microprocessor 150 when the complete registration ID transmitted through the wireless transmitter 210 of the remote control key 200 is received through the wireless receiver 110. This is a section for giving a command to change the wireless receiver 110 to the sleep mode by the control.

In the step (k '), it is the time when the locking device of the door lock 100 starts to be released. The release of the locking device of the door lock 100 is performed by the driving of the motor driving unit 190 under the control of the microprocessor 150.

In step (m '), the door open / close detection unit 168 detects that the door is closed. In this case, the door open / close detection unit 168, which is magnetic, detects this by closing the door by the user.

In the step (n '), it is a point of time that the locking device is corrected through the locking device locking / release detection unit 165.

The interval between step (m ') and step (n') is a constant time delay. This section is a section for giving a command to drive the motor driving unit 190 under the control of the microprocessor 150 after a predetermined time after detecting that the door is closed.

In step (o '), it is time to start the infrared projection through the infrared transmitter 122 again.

Here, unlike FIG. 7, before the predetermined time has elapsed since the wireless receiving unit 110 of the door lock 100 operates in the wake mode, the wireless receiving unit 110 receives the registration ID through the wireless receiving unit 110 to enter the sleep mode. Infrared projection from the infrared transmitter 122 is performed after the locking device is corrected again after unlocking.

In step (p '), the wireless transmitter 210 of the remote control key 200 starts to transmit one cycle registration ID. Prior to step (p '), the remote control key 200 is in an on state, and the wireless transmitter 210 transmits the registration ID of the remote control key 200 to the outside at regular intervals. On the other hand, if the remote control key 200 is not turned on before the step (p '), the remote control key 200 does not transmit the registration ID to the outside.

In the step (q '), it is a time when a predetermined shortcut button (not shown) installed in the outdoor side of the door lock 100 is pressed. However, the wireless receiver 110 of the door lock 100 is not operating in the reception standby state.

In one embodiment of the present invention, the registration ID transmission time is before the (q ') step in the wireless transmitter 210 of the remote control key 200, but this is arbitrary. For example, the time point may be after step (q ') or may be the same point in time as step (q').

In the step (r '), the wireless receiver 110 of the door lock 100 is a section in which the standby state is changed. From this point in time, the wireless receiver 110 of the door lock 100 receives the registration ID transmitted from the wireless transmitter 210 of the remote control key 200. The registration ID is received here but not the complete registration ID.

The period between step (q ') and step (r') is a time delay period from the time when the shortcut button of the door lock 100 is pressed to the reception standby state of the wireless receiver 110 under the control of the microprocessor 150. .

In step (s'), it is time to end the one-cycle registration ID transmission from the wireless transmitter 210 of the remote control key 200. At this point, the wireless receiver 110 of the door lock 100 is in a standby state for reception.

Here, the registration ID of the remote control key 200 is partially received through the wireless receiving unit 110, but not a complete registration ID. As a result, the lock release by the control of the microprocessor 150 is not made. The release of the locking device of the door lock 100 corresponds to a registration ID transmitted from the wireless transmitter 210 of the remote control key 200 and a registration ID stored in the registration ID input storage 130 of the door lock 100 in advance. Only if that happens.

In the step (t '), it is the time point at which the shortcut button input signal of the door lock 100 ends.

Here, the end point of the shortcut button input signal of the door lock 100 may be before step (r '), or may be between step (r') and step (s'), and may be the same as step (r ') or step (s'). It may be a time point.

In step (u '), it is the time point when the one-cycle registration ID transmission is started by the wireless transmitter 210. At this point, the wireless receiver 110 of the door lock 100 is in a standby state for reception.

In step (v '), it is the time point when the one-cycle registration ID transmission from the wireless transmitter 210 ends. At this point, the wireless receiver 110 of the door lock 100 is in a standby state for reception.

In the step (w '), the reception standby state of the wireless receiver 110 of the door lock 100 changes to the sleep mode.

The interval between step (v ') and step (w') is the microprocessor 150 when the complete registration ID transmitted through the wireless transmitter 210 of the remote control key 200 is received through the wireless receiver 110. This is a section for giving a command to change the wireless receiver 110 to the sleep mode by the control.

In the step (x '), it is the time when the locking device of the door lock 100 starts to be released. The release of the locking device of the door lock 100 is performed by the driving of the motor driving unit 190 under the control of the microprocessor 150.

In the interval between the step (w ') and the step (x'), the complete registration ID transmitted from the wireless transmitter 210 of the remote control key 200 is received by the wireless receiver 110 of the door lock 100, and the door lock 100 A time delay for driving the motor driving unit 190 through the microprocessor 150 of FIG.

In step (y '), the door open / close detection unit 168 detects that the door is opened. In this case, the door open / close detection unit 168, which is a magnetic sensor, detects this by the user opening the door.

There may be some time delay in steps (x ') and (y').

In step (z '), the door open / close detection unit 168 detects that the door is closed. In this case, the door open / close detection unit 168, which is magnetic, detects this by closing the door by the user.

In the step (z ''), it is a point of time that the locking device is detected through the locking device locking / release detection unit 165.

10 is a float chart illustrating a release / correction process and an open / close process of a door lock device according to an exemplary embodiment of the present invention. In this regard, the microprocessor 150 of the door lock 100 controls this process.

In step S10, it is determined whether the locking device of the current door lock 100 is corrected or released through the locking device locking / release detection unit 165. As a result of the determination in step S10, if it is determined that the locking device is corrected, the flow advances to step S20 to switch to the standby mode. On the other hand, if it is determined that the locking device is unlocked as a result of the determination in step S10, the process jumps to step S90.

In the standby mode, only the infrared detector 120 operates to detect a human body on the outdoor side of the door lock 100. As such, only the infrared detector 120 operates to reduce the power of the door lock 100 to a minimum. . Alternatively, in the standby mode, the power loss may be reduced to the minimum by using only a predetermined short-press button detected in the license plate formed inside the outdoor cover 185 of the door lock 100.

Next, the process proceeds to step S30 to determine whether the user access is detected through the infrared sensor 120.

Here, whether the user approach detection is determined whether the infrared rays projected through the infrared transmitter 122 are reflected by the human body and received by the infrared receiver 124. Alternatively, the user's approach may be detected by pressing a predetermined button (shortcut button) or an arbitrary button among the license plates formed inside the outdoor cover 185 of the door lock 100.

As a result of the determination in step S30, if the user's approach is not detected, step S30 continues. On the other hand, when the determination result in step S30, when the user's approach is detected and a human body detection signal is received, the process proceeds to step S40 and the wireless receiver 110 of the door lock 100 is in the reception standby state.

Next, the process proceeds to step S50 to determine whether the registration ID transmitted through the wireless transmitter 210 of the remote control key 200 has been received by the wireless receiver 110 of the door lock 100 in the reception standby state.

As a result of the determination in step S50, if the registration ID of the remote control key 200 is not received, the process proceeds to step S55 to determine whether a predetermined time has elapsed. As a result of the determination in step S55, if a predetermined time has not elapsed, the process returns to step S40. If the predetermined time has elapsed, the process returns to step S30 to proceed. On the other hand, if it is determined in step S50 that the registration ID of the remote control key 200 is received, the process proceeds to step S60 to determine whether the registration ID exists in the previously stored input registration ID.

As a result of the determination in step S60, if no search is made, the process returns to step S40 to proceed. On the other hand, if the registration ID search is made as a result of the determination in step S60, the process proceeds to step S70 and outputs a search occurrence sound through the melody generating unit 170. Here, whether or not the search occurrence sound is output is an optional matter and may proceed directly to step S80 in step S60. In addition, a separate light emitting diode (not shown) is installed on the outdoor side of the door lock 100 instead of outputting a search occurrence sound so that the user can visually confirm that the locking device of the door lock 100 has been operated. can do.

Next, the process proceeds to step S80 to drive the motor driving unit 190 to release the lock of the door lock 100 through the motor 195.

Here, step S70 and step S80 may also occur at the same time, it may output the sound of the search while releasing the lock of the door lock 100.

Next, the flow proceeds to step S90 to determine whether the door is opened through the door open / close detector 168. If it is determined in step S90 that the door has not been opened, the process proceeds to step S95 to determine whether a predetermined time has elapsed. On the other hand, if it is determined in step S95 that the predetermined time has elapsed, the process proceeds to step S120 to control the lock of the door lock 100 under the control of the microprocessor 150 to switch back to the locked mode.

On the other hand, if it is determined in step S90 that the door is open, the process proceeds to step S100 to determine whether the door opened in step S90 is closed again. If it is determined in step S100 that the door is not closed, step S100 is repeated. If it is determined in step S100 that the door is closed, the process proceeds to step S110 to determine whether a predetermined time has elapsed. .

If it is determined in step S110 that the predetermined time has not elapsed, step S110 is repeated to wait until the predetermined time elapses. On the other hand, when the determination result in step S110, if a predetermined time has elapsed since the door is closed, the process proceeds to step S120 to correct the lock of the door lock 100 under the control of the microprocessor 150 to switch back to the locked mode Done.
