Description

Door lock apparatus with intrusion notification function {Door lock apparatus with alarm of invasion}

The present invention relates to a door locking device, and more particularly, to a door locking device having an intrusion detection / notification function installed at an entrance door of an apartment or a front door of a house, a factory, etc. to detect and notify an intruder's intrusion attempt.

Door locks are installed on the entrance doors of apartments, houses, factories, etc. to prevent intrusion from outsiders. Such door locking devices may be broadly classified into mechanical types in which opening and closing operations are physically performed, and electronic types in which opening and closing operations are performed according to electrical input signals.

In order to open and close the door lock, a key or a password dial is used as the opening and closing medium in the case of mechanical type, and a password, which is a specific electrical input signal, is used as the opening and closing medium in the case of electronic type. Therefore, insiders are particularly careful not to share the opening and closing medium of the door lock device with outsiders.

However, even without the opening / closing medium, the intrusion of outsiders does not disappear, and even now, internal attempts by outsiders are constantly made. For this reason, various security devices have been developed and used. Usually, they are installed in windows, fences, parking lots, etc. to detect intruders, alarms, and surveillance.

However, the current security device is expensive, the general public is burdensome to install and difficult to manage, except for surveillance cameras do not immediately detect outside intrusion through the front door.

The present invention is to solve the above-mentioned problems, and provides a door lock device that immediately detects the intrusion of outsiders through the front door while in charge of opening and closing the front door to notify the outside of the intrusion.

Door lock device having an intrusion notification function according to the characteristics of the present invention for achieving the above technical problem is installed in the door or the front door, and equipped with a sensor to monitor the intrusion attempt of the intruder, It is provided with a wireless signal transmission unit for notifying the outside. On the other hand, intruders include insiders and outsiders, and outsiders are people with impure intentions and should be distinguished from insiders. The present invention uses the time from the time of intrusion detection to the time when the door lock device of the present invention is opened to distinguish between insiders and outsiders. If the insider has a password or a key, the door lock of the present invention will be opened within a short time, but if the outsider, the intrusion time will be longer than the insider. The present invention includes a CPU that controls the detection sensor and the wireless signal transmitter and is responsible for discriminating between insiders and outsiders. The present invention may further include a device for generating a predetermined sound to inform the start of the operation and a preliminary warning, and as the sound generating device, an alarm sound for notifying an outsider intrusion attempt can be generated. Alternatively, the present invention may further include a flashing unit that performs a predetermined display operation to notify the start of the operation and the preliminary warning, and may further include a sound generator that generates an alarm sound when an outsider attempts to invade.

Hereinafter, with reference to the accompanying drawings will be described a door locking device having an intrusion notification function according to an embodiment of the present invention.

1 is a block diagram of a door locking device having an intrusion notification function according to an embodiment of the present invention. As shown in FIG. 1, the door locking device according to the embodiment of the present invention includes a sensor 10, a timer 20, an input unit 30, a CPU 40, an alarm unit 50, and an RF (RadioFrequency). An electronic door locking device including a transmitter 60, a drive motor 70, a door opening and closing unit 80, a receiver 90, a remote controller 91, and an alarm unit 92.

Receiving unit 90, remote control 91 and the alarm unit 92 shown in dashed lines in Figure 1 is a part that can be removed by the manufacturer's intention.

The detection sensor 10 detects an intrusion attempt by an intruder and outputs an ON signal to the CPU 40 when the intrusion attempt is detected. The detection sensor 10 is a thermal sensor that detects heat emitted from a person within a certain distance. At this time, the predetermined distance is a distance to grasp the approach to the door lock device to intrusion.

Meanwhile, the detection sensor 10 is not limited to a thermal sensor, and may be a pressure sensor, a distance sensor, an optical sensor, a micro switch, a lead switch, or the like that can detect an intrusion intention of an intruder. have. For example, it may be possible to detect an intruder touching the door device, to detect the insertion of a key into the keyhole of the door lock, or to directly or indirectly through the door lock. It can be a sensor, a micro switch, a reed switch (also called a magnetic switch) that can detect an intrusion attempt to intrude into a network.

The timer 20 is countered in seconds by the control of the CPU 40, and is driven when a detection on signal is generated from the detection sensor 10. The timer 20 may be configured in hardware, but in general, since the CPU 40 supports a timer function in software, there is no need to configure the hardware.

The input unit 30 allows an insider to input a password or input other electrical signals to the device.

The alarm unit 50 generates an alarm sound under the control of the CPU 40, and the alarm sound is for a preliminary warning indicating that the device has been in lapse of time or is in operation, not an intrusion warning. Therefore, it is preferable that the preliminary warning beep sound is a small sound that does not greatly disturb the human ear. If the alarm unit 50 does not have a built-in device for generating an intrusion warning sound internally, the intruder warning sound is generated when it is determined that the intruder is not an insider but an outsider.

The RF transmitter 60 is a device that wirelessly transmits an intrusion or attempted intrusion as an RF signal under the control of the CPU 40.

The drive motor 70 is a device that provides a constant force under the control of the CPU 40.

The door opening and closing portion 80 is a device for mechanical operation to lock and open the door in conjunction with the force provided by the drive motor 70.

The receiver 90 is a device corresponding to the remote controller 91. The receiver 90 receives RF signals or other radio signals wirelessly transmitted from the remote controller 91 and provides the CPU 40 with information about the input signals. The remote controller 91 is a device for transmitting a radio signal corresponding to a user input.

The alarm unit 92 is a device for generating an alarm for intrusion warning, which is required when the alarm unit 50 performs a function for preliminary warning only.

The CPU 40 is an apparatus for controlling the overall operation of the apparatus, and performs an operation in which the features of the present invention are achieved according to a signal input from the sensor 10. Briefly, the timer 20 is driven in response to the detection signal of the detection sensor 10, and when the time measured by the timer 20 becomes the set time T1, T2, or T3, it detects whether the intruder continuously attempts to intrude. The preliminary warning sound is generated, the intrusion warning sound is generated, and the intrusion fact warning operation is determined as the detection signal of the sensor 10. T1 is a door open wait time, T2 is a door open margin time, and T3 is a final judgment time. Therefore, the CPU 40 causes the preliminary warning sound to be generated after the time T1 passes, and determines whether the door is normally opened after the time T2 passes, and determines whether the intruder has retired after the time T3 passes. It is determined whether to perform the notification.

The normal door opening means that the door lock device of the present invention is opened according to the password input.

The T1, T2, T3 can be arbitrarily determined, but it is set in consideration of the maximum time that the insider can normally open the door lock of the present invention and the minimum time that the outsider can abnormally open the door lock of the present invention. desirable. In the following description with reference to the drawings, T1 is described as 5 seconds, T2 as 8 seconds, and T3 as 10 seconds, but this is only one example.

The operation of the CPU 40 and the peripheral device is replaced by the description referring to FIGS. 3 and 4.

On the other hand, the present invention can be applied not only to the electronic, but also to the mechanical door locking device. When applied to a mechanical door locking device, a mechanical medium serving as a key is used instead of the input unit 30 and the receiving unit 90, and does not require the drive motor 70 and the door opening and closing unit 80.

2 is an installation state diagram of a door locking device having an intrusion notification function according to an embodiment of the present invention. As shown in Figure 2, the door lock device 100 of the present invention shows that the RF signal is transmitted to the surroundings by the RF transmitter 60 is installed in the front door and located inside the front door. The sensor 10 and the input unit 30 is installed on the outside of the front door, the sensor 10 is preferably installed close to the input unit 30 so as to easily detect the intruder's approach. This is because it is common for an intruder to operate the input unit 30 when invading. However, the detection sensor 10 is not limited to any mounting position, any position that can easily monitor the intruder.

On the other hand, when using the micro switch, the reed switch as the detection sensor 10 is installed in the interior of the device, the installation position is the outsider to operate the internal mechanism (parts) of the door lock device 100 in any form. It is preferable to be installed at a position that can be operated by a corresponding internal mechanism (or a deformed appearance) that is activated when opening or twisting the exterior of the device 100 or applying a deformation of the device 100 to operate.

3 is a view showing the RF signal transmission path of the door lock device having an intrusion notification function according to an embodiment of the present invention, the device receiving the RF signal of the RF transmitter 60 of the door lock device 100 of the present invention Are shown. As shown in FIG. 3, when the RF transmitter 60 transmits an RF signal, the indoor alarm 200, the secret camera 300, a home automatic (H / A) device, that is, the home automation device 400 and At least one of the remote controllers 91 receives the RF signal.

Since the remote control 91 is owned when going out, it is possible to check the intrusion attempt by an intruder even if it is not indoors. At this time, the remote controller 91 has a built-in RF signal receiving device, as well as a device for generating a predetermined alarm sound. However, since the remote control 91 can receive the RF signal of the door lock device 100 of the present invention within a predetermined distance from the device 100, the remote control 91 cannot receive the signal when it is out of the reception area.

The indoor alarm 200 operates by using the received RF signal as an operation start signal, and generates a predetermined warning sound during operation. The warning sound of the indoor alarm 200 is for the case that the intrusion warning warning sound of the door lock device 100 cannot be heard indoors.

Secret camera 300 may be installed anywhere within the range that can receive the RF signal, but the location to capture the face or appearance of the intruder, that is, installed in the elevator, indoors, the front door, apartment door, etc., RF Shooting operation starts when signal is received.

When the home automation device 400 receives an RF signal, the guard tells the guard room 500 of the warning signal through the communication line connected to the guard room 500 or the nearest police station.

Hereinafter, an operation of the door locking device having the intrusion notification function according to an embodiment of the present invention will be described with reference to FIG. 4.

4 is an operation flowchart of a door locking device having an intrusion notification function according to an embodiment of the present invention.

When the sensor 10 detects the intrusion of the intruder, the sensor 10 outputs the driving signal to the CPU 40 (S410).

When the CPU 40 receives a signal from the detection sensor 10, the CPU 40 checks the elapsed time from the intrusion detection time by driving the timer 20 (S411). The CPU 40 checks whether the intrusion of the intruder is maintained from the output of the sensor 10, and if 5 seconds elapse while the intrusion is maintained, the CPU 40 drives the alarm unit 50 to generate a warning sound for preliminary warning. (S430, S412, S413).

In this case, the fact that the intrusion is maintained means that the intruder continuously touches the door locking device 100 or continues within a certain distance as shown in FIG. 4, but the broader concept is shown in FIG. 4. Unlike the above, the intruder is not detected by the sensor 10 during the counter, but it is also detected in a predetermined time. In the second case, the CPU 40 measures the time for which the ON signal of the sensor 10 is not input to the counter, and compares the measurement time with the set time to invade when the measured time exceeds the set time. Judging by the suspension, and within the set time it can be determined to maintain the intrusion fact.

The CPU 40 determines whether the device 100 is normally opened within 8 seconds after the preliminary warning sound is generated through the alarm unit 50, and if it is determined that the device is normally opened, the CPU 40 determines to be an insider to stop the alarm and time measurement and alarm operation. Stop (S414, S415, S430, S417). However, if the device 100 is not normally opened within 8 seconds, it is determined whether the intruder has moved away from the device 100 within 10 seconds (S416). The determination at this time depends on the off signal of the sensor 10.

If the CPU 40 receives the OFF signal from the sensor 10 when the time measured by the timer 20 has elapsed 10 seconds, the CPU 40 determines that the intruder has withdrawn and stops the operation of the alarm unit 50 (S417). If, after 10 seconds has not received the off signal from the sensor 10, it is determined that the intruder is attempting to invade without retreating, and replaces the preliminary warning sound of the alarm unit 50 with the intrusion warning sound. Or, driving the alarm 92 to generate a warning sound for intrusion warning (S418).

At the same time, the CPU 40 drives the RF transmitter 60 to wirelessly transmit an RF signal informing of the intrusion warning (S419), so that the devices 91, 200, 300, 400, and 500 shown in FIG. To notify each user of the intrusion (S420).

The CPU 40 stops the time measurement and alarm operation when the ON signal is not received from the sensor 10 during a time measurement for a predetermined time.

On the other hand, the present invention, but the preliminary warning sound is to be generated through the alarm unit at the preliminary warning setting time, those skilled in the art can make a preliminary warning by flashing the warning light instead of the preliminary warning sound by using a blinking indicator.

As described above, the technical idea of the present invention has been described together with the accompanying drawings, but this is illustrative of the preferred embodiment of the present invention and is not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.

The present invention has the effect of preventing the intrusion of the inside from the outsider, and detecting the intrusion into the inside to alert the intrusion attempt to increase the security. In addition, the present invention has the effect of not having to use an expensive separate security device.
