The present invention relates to a wireless ID recognition digital door lock device having a security mode setting function and a method of controlling the same, wherein a remote control key while a wireless reception unit 110 (see FIG. 1) is in a waiting state in a door lock 100 (see FIG. 1). When receiving a registration ID periodically transmitted from the wireless transmitter 210 (refer to FIG. 2) of (200, see FIG. 2), it is determined whether the registration ID is searched for in the registered entry registration ID previously inputted to the door lock 100. Then, the password ID transmitted from the outdoor key input unit 185 (see FIG. 1) of the door lock 100 is input to the door lock 100 in advance to determine whether it is retrieved from the registered input password ID. When the registration ID and the password ID is retrieved together, the lock device of the door lock 100 is to be released.

1 is a schematic block diagram of a door lock according to the present invention. The door lock 100 includes a wireless receiver 110, an infrared detector 120, a registration ID input storage 130, a program storage 135, a number ID input storage 138, a power supply 140, and a microcomputer. Processor 150, low voltage detection unit 160, cover up / down detection unit 162, lock device correction / release detection unit 165, door open / close detection unit 168, melody generation unit 170, The indoor key input unit 180, the outdoor key input unit 185, the motor driver 190, and the motor 195 are configured to be included. The microprocessor 150 controls the overall operation of the door lock 100. The door lock 100 does not have a wireless transmitter, but only wireless reception is performed through the wireless receiver 110.

The wireless receiving unit 110 is connected to the microprocessor 150, and receives a radio signal including a registration ID transmitted from the wireless transmitting unit 210 of the remote control key 200 through a receiving antenna and demodulates the original signal. And digital conversion.

The infrared detector 120 is connected to the microprocessor 150 and includes an infrared transmitter 122 and an infrared receiver 124. For example, the infrared sensor 120 uses an infrared sensor, which operates in a sleep-wake mode.

The sensing distance between the infrared sensor 120 and the human body passing by is determined to be a suitable distance (for example, within 5 m). This is because if the sensing distance is too far, it also reacts to the human body passing by the surroundings, and if the sensing distance is short, the user has to go to a short distance in unlocking the lock of the door lock 100. There is a point to wait on the side. The longer the repetition period of the sleep-wake mode of the infrared sensing unit 120 is advantageous in terms of preventing power loss, but if the detection fails, the total detection time becomes longer, so that an appropriate time difference is provided.

The infrared transmitter 122 is composed of an infrared driver and a transmitter for transmitting the same. The microprocessor 150 drives the infrared driver to detect the human body, and the infrared driver drives the transmitter under the control of the microprocessor 150. When the transmission unit is driven to project the infrared rays, the projected infrared rays are reflected by the human body passing near the door lock 100.

According to the extraction instruction of the microprocessor 250 serves to send the corresponding ID registration start code and / and registration ID to the microprocessor 250. Here, the memory portion of the registration ID storage unit 220 is preferably implemented as a flash memory that can not only continue to store data even when the power is cut off, but also can read or rewrite arbitrary data. That is, the flash memory may be composed of a flash ROM or an electro-erasing ROM, ie, ypyrom.

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 is preferably implemented as a flash memory that can continue to store data even when the power is cut off. That is, the flash memory may be composed of a flash ROM or an electro-erasing ROM, ie, ypyrom.

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 to supply power for a long period of time, can also use a regular battery, and can be configured in various ways.

The low voltage detection unit 260 is connected to the microprocessor 250 and may cause a problem that the remote control key 200 does not operate because the voltage of the battery falls below a certain voltage, and the voltage of the battery is lower than the predetermined voltage. It serves to detect if 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.

On the other hand, if it is determined in step S20 that the input emergency number ID does not exist in the number ID input storage unit 138, the flow advances to step S30 to determine whether the emergency number ID is input.

If it is determined in step S30 that the emergency number ID has not been entered, the process proceeds to step S31 to determine whether a predetermined time has elapsed.

As a result of the determination in step S31, if the predetermined time has not elapsed, the process returns to step S30. If the predetermined time has elapsed, the process proceeds to step S32 to maintain the normal mode.

On the other hand, if the emergency number ID is input as a result of the determination in step S30, the emergency number ID is entered in step S40 and stored in the number ID input storage unit 138 as the input emergency number ID. Next, the process proceeds to step S50 to switch to the security mode.

As such, when the security mode is set, the infrared detecting unit 120 which is a means for detecting the user stops the operation. Whether the user senses whether the cover 186 is raised by the user, the cover rising signal is output or there is a button push signal generated by pressing a predetermined button or a predetermined button determined by the outdoor key input unit 185. It is possible in the case.

12A, 12B, and 12C are flowcharts illustrating a release / correction process of a locking device and an open / close process of a door according to an embodiment of the present invention. In this regard, the microprocessor 150 of the door lock 100 controls this process.

In step S100, 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. If it is determined in step S100 that the locking device is corrected, the process proceeds to step S110 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 S100, the process jumps to step S230.

In the standby mode of step S110, only a means for detecting a user (for example, a cover rising / falling detection unit 162 or an outdoor key input unit 185) is operated, and thus the user can be detected. By operating only the means, the power consumption of the door lock 100 can be reduced to a minimum.

Next, the process proceeds to step S120 to determine whether the user detection signal is received through the means for detecting the user.

Here, whether the user detection signal is received is determined by whether the cover rising signal through the cover rising / falling detecting unit 162 is received by the user raising the outdoor cover 186. Alternatively, the user's detection signal is output by pressing a predetermined button or a predetermined button in the license plate of the outdoor key input unit 185 when the outdoor cover 186 of the door lock 100 is not formed. It is determined by whether the detection signal is received.

As a result of the determination in step S120, if the user detection signal is not received, step S120 continues. On the other hand, when the determination result in step S120, when the user detection signal is received, the process proceeds to step S130 and the wireless receiver 110 of the door lock 100 is in the reception standby state.

Next, the process proceeds to step S140 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.

If it is determined in step S140 that the registration ID of the remote control key 200 is not received, the process proceeds to step S300 to determine whether a predetermined time t 1 has elapsed. As a result of the determination of step S300, if the predetermined time t 1 has not elapsed, the process proceeds to step S500.

In step S500, it is determined whether the emergency number ID is input from the outdoor key input unit 185. As a result of the determination in step S500, if the emergency number ID is not input, the process returns to step S140. On the other hand, if it is determined in step S500 that the emergency number ID is input, the process proceeds to step S510 to determine whether the entered emergency number ID is retrieved from the number ID input storage unit 138.

As a result of the determination in step S510, if the entered emergency number ID is not retrieved, the process proceeds to step S515 to determine whether a predetermined number of times n 2 (for example, three times) has elapsed.

As a result of the determination in step S515, when the predetermined number of times n 2 has not elapsed, the process returns to step S500. On the other hand, if the predetermined number of times n 2 has passed as a result of the determination in step S515, the flow advances to step S518 to stop the function of the outdoor key input unit 185 for a predetermined time ( t 4). After the elapse of the predetermined time t 4, the process returns to step S120.

On the other hand, if the emergency number ID is found as a result of the determination in step S510 proceeds to step S520 to terminate the reception standby of the wireless receiver 110. As such, by terminating the reception standby of the wireless receiver 110, power consumption of the door lock 100 may be reduced to a minimum. The flow then advances to step S170.

On the other hand, as a result of the determination in step S300, when a predetermined time ( t 1) has elapsed, the process proceeds to step S310 and ends the reception standby of the wireless receiver 110. As such, by terminating the reception standby of the wireless receiver 110, power consumption of the door lock 100 may be reduced to a minimum.

Next, the flow advances to step S320 to determine whether the emergency number ID is input from the outdoor key input unit 185. As a result of the determination in step S320, if the emergency number ID is not input, the process proceeds to step S325 to determine whether a predetermined time ( t 2) has elapsed.

As a result of the determination in step S325, when the predetermined time t 2 has not elapsed, the process returns to step S320. On the other hand, when the predetermined time t 2 has passed as a result of the determination in step S325, the process returns to step S120.

On the other hand, if the emergency number ID is input as a result of the determination in step S320, the process proceeds to step S330 to determine whether the input emergency number ID is retrieved from the number ID input storage unit 138.

If it is determined in step S330 that the emergency number ID is not retrieved, the process proceeds to step S335 to determine whether a predetermined number of times n 1 (for example, three times) has elapsed.

As a result of the determination in step S335, when the predetermined number of times n 1 has not passed, the process returns to step S320. On the other hand, when the determination result in step S335, the predetermined number ( n 1) has elapsed, proceeds to step S338 to stop the function of the outdoor key input unit 185 for a predetermined time ( t 3). After the elapse of the predetermined time t 3, the process returns to step S120.

On the other hand, if the emergency number ID is found as a result of the determination in step S330, the flow proceeds to step S170.

On the other hand, if it is determined in step S140 that the registration ID of the remote control key 200 is received, the flow proceeds to step S150 to determine whether the registration ID is searched for in the input registration ID previously stored in the registration ID input storage unit 130. To judge.

As a result of the determination in step S150, if the registration ID search is not performed, the flow proceeds to step S300. On the other hand, when the registration ID search is performed as a result of the determination in step S150, the process proceeds to step S160 to terminate the reception standby of the wireless receiver 110. As such, by terminating the reception standby of the wireless receiver 110, power consumption of the door lock 100 may be reduced to a minimum.

Next, the process proceeds to step S170 to output the primary search signal. The primary search signal may output a search occurrence sound through the melody generator 170. In addition, in another embodiment, a separate light emitting diode (not shown) or a liquid crystal display (LCD) (not shown) is installed on the outdoor side of the door lock 100 to output the search sound, thereby allowing the user to perform a first search. You can visually confirm that this has been done. In this case, whether the primary search signal is output may be optionally selected and proceeds directly to step S180.

Next, the flow advances to step S180 to determine whether a password ID has been input from the outdoor key input unit 185. If it is determined in step S180, that is, a password ID is input, the process advances to step S185 judges whether a predetermined time (t 6) has passed.

As a result of the determination in step S185, when the predetermined time t 6 has not elapsed, the process returns to step S180. On the other hand, if the predetermined time t 6 has elapsed as a result of the determination in step S185, the process returns to step S120.

On the other hand, if it is determined in step S180 that the password ID is input, the process proceeds to step S190 to determine whether the input password ID is retrieved from the number ID input storage unit 138.

If it is determined in step S190 that the password ID is not retrieved, the process proceeds to step S195 to determine whether a predetermined number of times n 3 (for example, three times) has elapsed.

As a result of the determination in step S195, when the predetermined number of times n 3 has not elapsed, the process returns to step S180. On the other hand, when the determined number n 3 has elapsed as a result of the determination in step S195, the flow advances to step S198 to stop the function of the outdoor key input unit 185 for a predetermined time ( t 5). After the elapse of the predetermined time t 5, the process returns to step S120.

On the other hand, if the emergency number ID is found as a result of the determination in step S190, the process proceeds to step S200 to output the secondary search signal.

The secondary search signal may output a search occurrence sound through the melody generator 170. In addition, in another embodiment, a separate light emitting diode (not shown) or a liquid crystal display (LCD) (not shown) is installed on the outdoor side of the door lock 100 to output a search sound, thereby allowing the user to perform a second search. You can visually confirm that this has been done. In this case, whether to output the second search signal is optional and proceeds directly to step S210.

Next, in step S210, it is determined whether the lock release signal is input.

The lock release signal indicates a cover drop signal generated by sliding down the cover 186 formed on the outdoor side by the user.

If it is determined in step S210 that the lock release signal is not input, the flow advances to step S215 to determine whether a predetermined time t 7 has elapsed.

If it is determined in step S215 that the predetermined time t 7 has not elapsed, the process returns to step S210. On the other hand, if it is determined in step S215 that the predetermined time t 7 has elapsed, the process returns to step S120.

On the other hand, if it is determined in step S210 that the lock release signal is input, the flow proceeds to step S220.

Here, in one embodiment in which the cover 186 is formed, such steps S210 and S215 exist, which is optional, and may proceed directly from step S200 to step S220. That is, the user may proceed to step S220 immediately after the secondary search signal is output without inputting the lock release signal.

Further, in another embodiment in which the cover 186 is not formed (for example, when the cover 186 is not formed on the outdoor side of the door lock and formed of a license plate), such steps S210 and S215 do not exist. Instead, the process may proceed directly from step S200 to step S220. That is, after the final password ID input signal (for example, a * button press signal or a # button press signal) is input by the user in step S180, the step is controlled by the microprocessor 150. If the password ID input in step S190 is retrieved from the number ID input storage unit 138, the second search signal may be output and the process may proceed directly to step S220.

In step S220, the motor 195 is driven through the motor driver 190 to release the lock of the door lock 100.

Next, the process proceeds to step S230 to determine whether the door is opened (open) through the door open / close detection unit 168. If it is determined that has not been determined that the doors open in the step S230, the process advances to step S235 and determines whether a predetermined time has elapsed (t 8).

As a result of the determination in step S235, when it is determined that the predetermined time t 8 has not elapsed, the process returns to step S230. On the other hand, if it is determined in step S235 that the predetermined time t 8 has elapsed, the process proceeds to step S260.

On the other hand, if it is determined in step S230 that the door is open, the process proceeds to step S240 to determine whether the door opened in step S230 is closed again.

If it is determined in step S240 that the door is not closed, step S240 is repeated. On the other hand, if it is determined in step S240 that the door is closed, the process proceeds to step S250 to determine whether a predetermined time t 9 has elapsed.

If it is determined in step S250 that the predetermined time has not elapsed, step S250 is repeated to wait until the predetermined time t 9 elapses. On the other hand, if the predetermined time ( t 9) has passed as a result of the determination in step S250, the process proceeds to step S260 to correct the locking device of the door lock 100 under the control of the microprocessor 150 to switch back to the locked mode. do.
