1 to 5, a security system according to an embodiment of the present invention includes:

A security system (100) for receiving sensing information from at least one sensing device,

A sensing information receiving unit 120 for receiving sensing information from the sensing device;

A status display unit 110 for displaying the detection information received from the sensing device on a screen;

A storage unit 160 for storing the sensing information;

A sensing information control unit 130 for transmitting to the external user smartphone that the sensing information has been received and providing the sensing information in response to the smartphone request;

And a sensing information communication unit 140 for performing a communication function with the smartphone 300.

The sensing device (200)

A touch sensor unit 230 having a sensor pattern of at least a pair of dual microstrip structures and sensing a touch of a human body;

An ultrasonic sensor part 240 for monitoring at least one external condition within a predetermined distance independently or in real time;

A camera unit 250 for capturing an external part to be monitored;

A control unit for driving the camera unit 250 to capture an image when the intrusion is detected by the ultrasonic sensor unit 240 or the touch sensor unit 230 and to output sensed information including photographed photographing information to the outside, (220);

And a communication unit 222 for transmitting the sensing information to the sensing information receiving unit under the control of the controller.

The control unit 220 is formed on the PCB substrate together with the timer 221 and the communication unit 222 and a ground pattern unit may be formed on the opposite side of the substrate 220 on which the control unit 220 is formed.

The sensor pattern is formed by symmetrical strip lines and has an impedance matching structure. The number of strip lines can be varied.

The ground pattern portion is formed of a copper foil, and a pattern of a net-like pattern may be inscribed.

Referring to FIG. 3 or 4, the touch sensor unit 230 is integrally installed on the outside or inside of a window, a door, or the like which an intruder may touch or touch.

The ultrasonic sensor unit 240 is installed on an access door or a window accessible by an intruder.

The camera unit 250 installs the intruder at a photographable angle at the time of intrusion.

Here, if necessary, a plurality of touch sensor units 230, an ultrasonic sensor unit 240, and a camera unit 250 are installed, and they can be selectively used. A monitoring device is installed at each place to be monitored.

The touch sensor unit 230 further includes a metal pattern unit having a metal wire structure or a mesh-like structure, and an example of this is shown in FIG.

The metal pattern portion may be an insect screen or a metal material, and may be a part of a porch railing.

The sensor pattern of the touch sensor unit 230 is formed such that the first strip line and the first strip line are symmetrical to each other and the first and second strip lines are impedance matched. Or attached to the outside.

The controller 220 may include a timer 221 for checking the time and the controller 220 may operate the camera 250 when the sensing signal of the touch sensor 230 is received .

When the ultrasound sensor unit 240 detects a signal, the control unit 220 refers to the timer 221 and operates the camera unit 240 when the ultrasound sensor unit 240 is continuously detected for 3 to 5 seconds.

The control unit 220 can immediately operate the camera unit 250 when a signal from the ultrasonic sensor unit 240 and a signal from the touch sensor unit 230 are simultaneously detected.

In addition, the embodiment of the present invention includes a CVD-type control unit 220 that is stronger in noise and less sensitive to sensed values than a conventional frequency-based sensor.

In the embodiment of the present invention, when an object such as a human body approaches the electrode plate, electrostatic induction is induced, so that the charges inside the object move (-) charge toward the electrode plate and (+) charge move to the opposite side. This phenomenon is called polarization phenomenon.

If the object moves away from the electrode plate, the polarization becomes weaker and the capacitance decreases. On the contrary, when the electrode plate approaches the electrode plate, the polarization becomes larger and the (+) charge of the electrode plate increases and the capacitance increases. . Here, the sensor pattern serves as an electrode plate.

The relative dielectric constant of an object is shown in FIG.

6 is a graph showing the relative dielectric constant of an object.

6, air has a relative dielectric constant of 1 and the lowest. Acrylic is 2.7 to 4.5, FR-4 is 4.6, and tempered glass is 7.3.

8 is a waveform when an object according to an embodiment of the present invention is not detected, and FIG. 9 is a graph showing the waveform of an object according to an embodiment of the present invention. It is the waveform when it is detected.

7, the capacitance is a value obtained by dividing the distance between the plates by the value obtained by multiplying the permittivity of the free space by the state dielectric constant and the plate area. That is, as the area of the touch sensor unit 230 is large, the dielectric constant depending on the cover material is high, or the thickness of the cover is thin, more static capacitance value is generated.

On the other hand, the smaller the sensing area of the sensor pattern is, the smaller the sensing value is.

The sensing area is generally 10 mm 2 on the face recognized when a finger is detected in the case of a touch sensor. This effect can be stabilized by disposing a ground pattern portion on the opposite surface of the sensor pattern portion to form an initial capacitance value.

Therefore, when the sensor pattern area is wide, a ground pattern portion is generated to give a large initial capacitance value. If the area of the sensor pattern is small, the distance from the ground pattern portion should be taken into consideration and relatively far away. This is because the sensing capacitance does not have to be so high that it should not be tied to the initial capacitance value.

And the ground pattern part is needed to reduce the SNR.

Signal to noise ratio (SNR) is a signal-to-noise ratio. In order to reliably distinguish between sensing and non-sensing conditions, noise peak-to-peak variation and signal strength need to be much larger than noise. The recommended signal is 5: 1 and at least 5 times the noise.

Providing the ground pattern portion 300 on the PCB substrate helps to reduce the capacitive sensing RF noise.

The operation of the security system having such a configuration will be described below.

First, when an intruder approaches a window or a door, an intrusion is detected by the touch sensor unit 230 or the ultrasonic sensor unit 240.

Then, the control unit 220 drives the camera unit 250 to photograph, and outputs sensed information including photographed photographing information to the outside.

The control unit 220 may include a timer 221 for checking the time and the control unit 220 may directly receive the sensing signal from the touch sensor unit 230 When a signal of the ultrasonic sensor unit 240 is sensed, the camera unit 250 can be operated when it is continuously sensed for 3 to 5 seconds with reference to the timer.

The control unit 220 can immediately operate the camera unit 250 when a signal from the ultrasonic sensor unit 240 and a signal from the touch sensor unit 230 are simultaneously detected.

Then, the control unit 220 outputs the sensed information, such as whether the ultrasound signal is sensed or the sensed by the touch sensing unit 230, through the communication unit 222, together with the photo information taken at predetermined intervals in the camera unit 250 .

Thereafter, when the sensing signal is received from the communication unit 222 by the sensing signal receiving unit 120, the sensing information control unit 130 stores the received sensing information in the storage unit 160 and displays the sensing information on the screen of the display unit 110 .

At this time, the user can see the current monitoring situation by viewing the screen of the display unit 110. [

Meanwhile, the monitoring information control unit 130 transmits to the external user smartphone 300 through the sensing information communication unit that the sensing information has been received. At this time, if necessary, it may be a computer or a tablet PC instead of a smart phone.

Then, the user recognizes that the sensing information is received through the application of the smartphone 300, and communicates with the sensing information control unit 130 to confirm the sensing information immediately or at a later time. At this time, the sensing information may be information such as a photograph, an ultrasonic sensor, or a touch sensor.

According to the embodiment of the present invention, the detection function of various external environments and intrusion conditions is enhanced in addition to the proximity sensor of the ultrasonic type, thereby monitoring real-time intrusion situations and enabling the user to immediately respond to security alarms.

According to the embodiment of the present invention, when a human body is sensed by a capacitive CVD type sensing pattern used for human body sensing, the sensor senses the contact of the human body by recognizing the changed electrostatic capacitance value, And can immediately alert the user of the status information.

In addition, the CVD method used in the embodiment of the present invention is strong against noise, has a relatively small amount of change according to temperature, has a small error value, and can accurately detect a human body, so that direct contact or indirect contact can be accurately performed.

In addition, in the embodiment of the present invention, it is possible to monitor real-time intrusion situations and to enable a user to immediately respond to security by enhancing detection functions for various external environments and intrusion conditions.

In addition, the embodiment of the present invention can be implemented with a small cost.

In addition, real-time security is possible by allowing the user to check sensor detection and detection information at a desired time after a real-time or event occurrence through a dedicated monitor.

Also, in the embodiment of the present invention, the error can be reduced by a structure having at least one pair of impedance-matched dual micro strip patterns and a mesh ground pattern at the opposite side.

In addition, in the embodiment of the present invention, it is possible to perform a crime prevention function at a low cost by using a conductive material such as an insect screen net or a railing already installed.

The embodiments of the present invention are applicable not only to residential and residential spaces but also to factories and buildings requiring security.
