Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insect net security system for preventing theft and intrusion using impedance change,

More particularly, the present invention relates to an insect security system for preventing theft and intrusion, and more particularly, to an intruder detecting a change in an impedance of an insect control network when an insect is cut, detecting the occurrence of an intrusion, To thereby prevent theft and intrusion, thereby preventing theft and intrusion.

In general, the main intrusion path of an outsider for intentional intrusion into a house or a building is through a window that is easy to open or break.

Therefore, in order to detect unauthorized intrusion by an outside person, a sensor for detection is attached to a window frame or a window frame adjacent to the window frame so that the anti-theft device is operated according to whether the window is open or closed.

For this purpose, a method of using a bidirectional infrared sensor as a conventional anti-theft means and a method of installing a barrier on a window by a pipe or the like are widely used.

When a bidirectional infrared sensor is used, the price of the sensor is high, and even when the angle of the face-to-face sensor changes slightly, the sensor is easily stopped and misreporting occurs.

In addition, since the structure of the anti-theft device must depend only on the operation of the sensor, it can not perfectly cope with the intrusion of the trespasser, and the intruder can easily recognize the position of the sensor, And are exposed to intrusion through windows.

Pipe, etc., it is not economically advantageous due to the cost relationship due to the supply and demand of the material, and also acts as a factor that hinders the rapid escape in the case of internal disaster and other emergency situations. Therefore, It is pointed out that it is structurally very unreasonable.

The server means 400 may also be configured to transmit the abnormality information to the user smartphone 500 when the relay means 300 does not transmit abnormality information to the user smartphone 500.

Hereinafter, the configuration means of the present invention will be described in detail.

The insect-proof door 100 is installed in a window or a veranda, and is composed of an insect control net 110 in which a metal net made of conductive material is formed in a net shape and a frame formed around the insect control net. The insecticide door 100 is used for insect pest control and crime prevention and is installed for the safety of a child.

The sensing means 200 is installed at one side of the insect gates 100 in a clipping manner or a pressing manner and is electrically connected to the insecting net 110 to detect a change in the impedance of the insecting net 100. The sensing means 200 detects changes in impedance due to insect damages , It generates abnormality occurrence information.

To this end, the sensing means 200 senses a change in the impedance of the insecting net using a change in current flowing in the insecting net or a change in potential difference between specific two points of the net insecting net to detect an impedance change.

As shown in FIG. 5, the sensing unit 200 includes a voltage application control unit 210 configured to automatically apply a voltage applied to the insect-proofing network 110 according to time;

An impedance sensing unit 220 sensing an impedance change of the insecting net when a voltage is applied to the insecting net 110;

Information on the voltage value to be applied to the insect-proofing network 110, information on the impedance value of the insecting net, information on a normal current value flowing in the insect-protection net in a normal case, and information on a voltage value to be measured in a normal case A storage unit 230 for storing information on the information;

It is determined whether the impedance change sensed by the impedance sensing unit 220 is a change due to a living environment such as rain, snow, or the like, or a change due to an insect damper failure. If the impedance change is a change due to an insect damper breakage, (240);

And a transmitting unit 250 configured to transmit the anomaly signal generated by the determining unit 240 to the relaying unit 300.

The sensing unit 200 may further include a speaker unit 260. The speaker unit 260 may provide a warning sound or a warning alarm to the intruder when the determination unit 240 generates an anomaly signal .

The voltage application control unit 210 is formed to apply a preset voltage to the insect-proofing network 110, and the voltage value of the applied voltage is automatically changed with time.

The basic technical idea of the present invention is as follows.

When a voltage is applied to an insect net, which is a metallic mesh made of a conductive material, a current flows through the insect net. The voltage value applied to the insect net and the impedance value of the insect net are already known (it is written in the storage section). Therefore, the insect current has a known current value (applied voltage ÷ insect net input A steady current that is a current corresponding to a current value (i.e., a power supply value) flows.

However, if the intruder cuts the insect screen for an intrusion attempt, the impedance of the insect screen changes, and when the impedance changes, the current value flowing through the insect screen changes. That is, it is judged that the current flowing in the insecting net flows not the normal current value but the intrusion occurs in this case.

However, if the intruder knows the impedance value and the applied voltage value of the insect screen in advance and attempts illegal penetration by using the jump line and special equipment, the current flowing in the insect screen may flow the normal current value even though the insect screen is cut off.

In this case, in order to detect an illegal intrusion, the voltage applied in the present invention may be changed over time according to time.

In other words, if the voltage applied to the insect net is arbitrarily changed over time, the intruder will not know what voltage is applied to the insect net, so that even if a jump line or special equipment is used, the normal current value can not be passed.

Information on the applied voltage which is changed at any time and information on the steady current value corresponding thereto are previously stored in the storage unit of the sensing means 200. If a current other than the steady current flows, .

 To this end, the voltage application control unit 210 includes a power supply unit 211 configured to supply a voltage using a battery or an external power supply;

And a conversion unit 212 configured to change the voltage of the power source unit 211 according to time and supply the voltage to the insect control network 110.

The power source unit 211 may be a battery formed inside the sensing unit 200, or may be a constant power source supplied from the outside.

The conversion unit 212 converts the voltage supplied to the insecting net 110 according to time and converts the changed voltage value according to the voltage supply schedule table stored in the storage unit 230 and supplies the converted voltage value to the insect- .

The impedance sensing unit 220 is electrically connected to the inspecting net 110 to detect a change in the impedance of the insecting net 110 when a voltage is applied to the insecting net 110.

FIG. 3 shows an example of the electrical connection between the contact terminal 221 of the impedance sensing unit 220 and the screen guard net.

The impedance sensing unit 220 may use a current sensing scheme or a voltage sensing scheme to sense an impedance change of the insect control network.

When the current sensing scheme is used, the impedance sensing unit 220 is electrically connected to the inspecting net 110 and includes a contact terminal 221 formed to apply a voltage provided from the voltage application control unit 210 to the insecting net 110, Wow;

A current sensing unit 222 for sensing a current flowing through the insecting net 110 when a voltage is applied to the contact terminal 221; And a control unit.

In this case, the contact terminal 221 is provided for electrical connection between the screen inspecting net 110 and the sensing means 200. The contact terminal 221 is formed of two contact terminals, The current flows through the insect-proofing net 110. FIG.

When a current flows through the insect control network, the current sensing unit 222 senses a current value flowing through the insect control network.

At this time, there are various positions where the two contact terminals 221 make electrical connection with the insect screen, and an example is shown in Fig.

The two points at which the two contact terminals and the screen guard are electrically connected may be P1, P2 in Fig. 6, or P3, P4. At this time, it is preferable that the two points are farther away from each other. The reason is that as the electrical connection points are farther away from each other, the impedance change detection becomes more accurate. 3 and 6 illustrate the electrical connection points between the contact terminals and the screen guard. At this time, the electrical contact points of the two contact terminals and the screen net can be connected by a lead wire.

When an applied voltage varying with time is applied to the insecting net, a current flows to the insecting net through the contact terminal 221, and the value is as shown in the following Equation 1, and the current sensing unit 222 senses the value.

[Equation 1]

Sensing current = (applied voltage / insect net impedance)

In a normal case where the impedance of the insecting net is not changed, the sensing current value flowing through the insecting net due to the applied voltage varying with time is the same as the value stored in advance in the storage unit as the normal current value.

The storage unit stores a variable applied voltage value, an insect net impedance value, and a steady current value that is a current value corresponding to the applied voltage and the impedance value.

That is, when a normal applied voltage is applied to the insect control network, a normal current corresponding to the applied voltage flows to the insect control network.

However, the impedance of the insecticide is changed by the various factors (damage of the insect screen caused by illegal intrusion, change of the surrounding environment of the snow, boiling, etc.), and the overall impedance of the insect screen is changed. At this time, the current value flowing through the insect control network changes. That is, if the current value flowing through the network is changed, the total impedance of the screen is changed. This means that the screen is damaged due to illegal intrusion, or the surrounding environment is changed due to snow, rain or the like. At this time, the current sensing unit 222 senses a changed current value according to an impedance change of the insect control network.

For example, if the normal current value to be applied to the screening gate for a certain applied voltage is 1 A (when there is no screening damage due to an intrusion or a change in the surrounding environment due to an intrusion), the current value flowing through the screening gate is 0.8 A , It means that the total impedance of the screen net is changed by some cause (breakage due to cutting or change of surrounding environment).

When the voltage sensing method is used, the impedance sensing unit 220 is electrically connected to the inspecting net 110 and supplies a voltage provided from the voltage applying control unit 210 to a contact terminal 221);

And a voltage sensing unit 223 for sensing a potential difference between two specific points of the insect control network 110 when a voltage is applied to the contact terminal 221. [

The contact terminal 221 is provided to apply an applied voltage varying with time to the insecting net through the electrical connection between the insecting net 100 and the sensing means 200. The contact terminal 221 is formed of two contact terminals, The applied voltage which varies with time is applied to the specific point of the screen net, for example, at points P1 and P2 in Fig. At this time, the voltage sensing unit is connected to specific two points of the screening network (for example, points P3 and P4 in FIG. 7, to which the sensing voltage is to be measured by the voltage sensing unit).

As a result, the screen inspecting network is provided with two points (for example, points P1 and P2 in FIG. 7) electrically connected to the contact terminals and another two points electrically connected to the voltage sensing unit 223 (for example, points P3 and P4 ).

The two contact terminals 221 may be electrically connected to the insect control network at various positions, and the two points at which the two contact terminals and the insect control net are electrically connected are preferably as far apart as P1 and P2 in FIG. The reason is that as the electrical connection points are farther away from each other, the impedance change detection becomes more accurate.

For the same reason, the two points at which the voltage detection unit 223 and the insecting net are electrically connected are preferably as far apart as P3 and P4 in Fig.

At this time, the electrical contact points of the two contact terminals or the voltage sensing part and the screen guard can be connected by a wire.

When the applied voltage varying with time is applied to the insect control network, the sensing voltage according to the impedance change of the insect control network is measured by the voltage sensing unit 223 connected to another point (for example, points P3 and P4 in FIG. 7) of the insect control network .

가 감지전압이 되는 것이며 하기 수학식2에 의해 결정된다.As shown in FIG. 7, the voltage across the both ends of the galvanometer system of the voltage sensing unit 213

Is the sensing voltage and is determined by the following equation (2).

Is the same as the value stored in advance in the storage unit as the normal voltage. However, when the insect damage or the living environment changes due to intrusion,

Has a different value from the normal voltage stored in the storage unit.

That is, in a normal case where the impedance of the insecting net is not changed, the voltage value sensed by the voltage sensing unit due to the applied voltage varying with time is the same as the value stored in the storage unit in advance as the normal voltage value.

In the storage unit, a steady voltage value to be measured by the voltage applying unit 223 is stored when the applied voltage value and the insect net impedance value vary in advance and the applied voltage value and the impedance value are applied.

That is, when a normal applied voltage is applied to the insect control network, a normal voltage corresponding to the applied voltage is sensed by the voltage sensing unit.

However, the impedance of the insectproof room is changed by various causes (damage of the insect screen due to illegal invasion, change of the surrounding environment of the snow, boiling, etc.), and the overall impedance of the insect screen is changed. At this time, the voltage value measured by the voltage sensing unit changes. That is, if the voltage value measured by the voltage sensing unit is different from the normal voltage, it means that the total impedance of the screening network is changed. This means that the screening network is damaged due to illegal intrusion, or the surrounding environment has changed due to snow, rain or the like. At this time, the voltage sensing unit 223 senses a changed voltage value according to the impedance change of the insect control network.

For example, if the normal voltage value to be measured in the voltage sensing section for a specific applied voltage is 1 V in normal cases (no damage to the insect screen due to intrusion or change in the surrounding environment) If the measured voltage value is changed to 0.8V, it means that the total impedance of the screen net is changed by some cause (breakage due to cutting or change of the surrounding environment).

The variable voltage value applied to the insecting net 110 through the voltage application control unit 210 and the impedance value of the insecting net 110 are stored in the storage unit 230 in advance. Since the impedance of the insect net varies depending on the physical size (area, etc.) of the insect net, the impedance value of the insect net used by the current user is stored and set.

Also, in the normal case, the storage unit stores a steady-state current value to be supplied to the screening network and a steady-state voltage value to be measured by the voltage sensing unit.

In addition, the voltage supply schedule table indicating the applied voltage value varying with time can be stored in the storage unit 230, and the applied voltage applied to the insect screen according to the schedule table can be automatically set to change with time .

The variable time interval of the applied voltage can be changed arbitrarily according to the user setting, and it is preferable to set the minute unit such as 1 minute, 2 minutes, 3 minutes and 5 minutes.

2, when a plurality of inspecting networks are provided with a plurality of sensing means, unique information of each sensing means 200 may be stored in the storage unit 230, It can be a unique number.

The determination unit 240 may determine whether an intrusion caused by breakage or disconnection of the insect control network 110 using the current value or the voltage value sensed by the current sensing unit 222 or the voltage sensing unit 223 of the impedance sensing unit 220 .

First, a process of determining whether or not the insect screen network is damaged using the current value sensed by the current sensing unit 222 will be described.

The current sensed through the current sensing unit 222 is classified into two types.

The first is the detection of normal current.

The steady current is a current value according to the applied voltage value stored in the storage unit and the impedance value of the screen guard. Since the stored voltage value and the impedance value of the insect screen network are stored in the storage unit over time, the current value in a normal case can be known from this. If the current value sensed by the current sensing unit is a normal current value stored in the storage unit, the determination unit determines that the current state is normal.

The second is the detection of steady current and other current.

The fact that the normal current and the other current are detected means that the impedance of the screening net 110 is changed.

The reason why the impedance of the insect net changes is the change of the living environment due to the breakage by the insect cutting or tearing by the intruder and the snow and the rain.

However, in the case of the impedance change due to the living environment such as snow, rain, etc., it is judged as a normal case. Therefore, the impedance change due to the living environment change and the impedance change due to the insect net damage are judged by using the current change rate .

&Quot; (3) &quot;

Current change rate = (steady current / sense current)

(In this case, the current value stored in the storage unit as the current value flowing through the screening network in a normal case corresponding to the sensing current: the current value sensed by the current sensing unit, the normal current: the applied voltage)

The determination unit 240 determines whether the current change rate is within a predetermined change rate. As a result of the determination, if the impedance is within a preset change rate, the impedance is determined to be a normal impedance change. If the impedance change is greater than a preset change rate, the impedance is determined to be abnormal.

A normal impedance change means an impedance change due to a change in living environment such as a pest, rain, snow, etc. An abnormal impedance change means an impedance change due to an insect damper breakage such as cutting or tearing of an insect screen due to an illegal invasion.

The predetermined rate of change may be arbitrarily set by a user, and is preferably 1 + - 0.2.

For example, when the current change rate is between 0.8 and 1.2, it is determined to be normal, and when the current change rate is less than 0.8 and more than 1.2, it can be judged as abnormal.

If the current change rate is between 0 and 8-1.2, the reason for determining that the current is normal is that the impedance may change even in a change in the living environment such as snow and boiling. Therefore, the impedance change due to the change in the living environment is judged to be normal .

If the determination unit 240 determines that the impedance is abnormal, the controller 240 generates an abnormal signal and transmits the abnormal signal to the relay unit through the transmitter 250. Also, if the speaker unit 260 is provided, the speaker unit 260 can be transmitted.

Next, a process of determining whether or not the insect screen network is damaged using the voltage value sensed by the voltage sensing unit 223 will be described.

The voltages sensed through the voltage sensing unit 223 are classified into two types.

The first is the detection of steady voltage.

The normal voltage is a value stored in the storage unit as a voltage value to be sensed by the voltage sensing unit in a normal case according to the applied voltage value stored in the storage unit and the impedance value of the screen guard.

Since the voltage value to be measured in the normal voltage sensing unit is stored in correspondence with the applied voltage value varying with time, the impedance value of the screening network, the applied voltage value and the impedance value, The voltage value to be measured can be known.

If the voltage value detected by the voltage sensing unit is a normal voltage value stored in the storage unit, the determination unit 240 determines that the voltage is normal.

The second is the detection of a steady voltage and a different voltage.

The fact that the normal voltage and the other voltage are detected means that the impedance of the screening net 110 is changed.

The reason why the impedance of the insect net changes is the damage of the insect net by the intruder and the change of the living environment due to snow, rain, and the like.

However, in the case of the impedance change due to the living environment such as snow, rain, etc., it is judged as a normal case. Therefore, the impedance change due to the living environment change and the impedance change due to the insect net damage are discriminated .

&Quot; (4) &quot;

Voltage change rate = (steady voltage / sense voltage)

(Voltage value sensed by the voltage sensing unit, normal voltage: voltage value stored in the storage unit as a voltage value to be measured by the voltage sensing unit in a normal case corresponding to the applied voltage)

The determination unit 240 determines whether the voltage change rate is within a predetermined change rate. As a result of the determination, if the impedance is within a preset change rate, the impedance is determined to be a normal impedance change. If the impedance change is greater than a preset change rate, the impedance is determined to be abnormal.

A normal impedance change means a change in impedance due to a change in living environment such as rain, snow, etc. An abnormal impedance change means an impedance change due to an insect damper breakage such as cutting or tearing of an insect screen due to illegal intrusion.

The predetermined rate of change may be arbitrarily set by a user, and is preferably 1 + - 0.2.

For example, when the voltage change rate is between 0.8 and 1.2, it is determined that the voltage change rate is normal. If the voltage change rate is less than 0.8 and the voltage change rate is more than 1.2, it can be determined that the voltage change rate is abnormal.

If the voltage change rate is between 0,8 and 1.2, the reason for the determination is that the impedance may change even when the living environment of the eye or boil changes, so that the impedance change due to the change in the living environment is judged to be normal .

If the determination unit 240 determines that the impedance is abnormal, the controller 240 generates an abnormal signal and transmits the abnormal signal to the relay unit through the transmitter 250. Also, if the speaker unit 260 is provided, the speaker unit 260 can be transmitted.

The transmission unit 250 is configured to transmit the abnormal signal generated by the determination unit 240 to the relay unit 300.

The sensing unit 200 may further include a speaker unit 260. When the speaker unit 260 receives the abnormal signal from the determination unit 240, Provide a warning alarm to the intruder.

When the speaker unit 260 is provided, a warning sound or a warning alarm is further stored in the storage unit 230.

According to the setting of the user, the warning voice or warning alarm may be selected from a warning voice or a warning alarm, or may be provided with a combination of a warning sound and a warning alarm.

The warning voice may be "You are currently attempting an illegal intrusion "," Illegal intrusion has been sent to the police station ", and the warning alarm may be "Siren or whistling sound ".

2, when a plurality of sensing units 200 are formed in a plurality of insect-proofing networks 110, the abnormal information transmitted to the relay unit 300 includes unique information of the sensing units 200 Can be transmitted together. At this time, the unique information may be a unique number of the sensing means 200, and the unique information is stored in advance in the storage unit 230.

In this case, the abnormality occurrence information and the detection means inherent information transmitted to the relay means 300 may be transmitted in the form of "occurrence of abnormal detection number _ more than once ". For example, it may be "01 _ abnormal occurrence", "03 _ abnormal occurrence" or the like.

In this case, the identification number of the sensing means may be designated, for example, 01 as a veranda screening network detection warning means, 02 as an inner screening network detection warning means, and 03 as a small screening network detection warning means.

The relay unit 300 includes an information receiver 310 configured to receive an abnormal signal from the sensing unit 200 as shown in FIG. 5;

An abnormality occurrence information generating unit 320 for generating abnormality occurrence information including information indicating whether the insect-proofing network 110 is damaged or not and damage time using the abnormality occurrence signal transmitted from the sensing unit 200;

The information receiving unit 310 is configured to receive a generated abnormal signal transmitted from the sensing unit 200.

In addition, when a plurality of sensing units 200 are provided, unique information of the sensing unit 200 may be received together with the abnormal generation signal.

The abnormality occurrence information generation unit 320 generates the abnormality occurrence information using the abnormality occurrence signal of the sensing means 200 transmitted through the information reception unit 310.

In this case, the abnormality occurrence information may include information on the abnormality occurrence time and the abnormality occurrence feature. For example, "cracking due to cutting at 10:30 ", and the like.

When a plurality of sensing units 200 are provided, the abnormal information may further include unique information of the sensing unit 200.

For example, "breakage due to cutting at 10:30 of the main screen web screen" or "break-in break at 11:00 of the main screen web screen"

The information transmitter 330 transmits the abnormal information generated by the abnormal information generator 320 to the server 400 or the user smartphone 500.

In addition, the relay means 300 may further include a smartphone number setting unit for setting the number of the user smartphone to transmit the abnormality occurrence information.

And the relaying unit transmits the abnormality occurrence information to the set smartphone when the smartphone number for transmitting the abnormality occurrence information is set through the smartphone number setting unit.

The server means 400 transmits the abnormality occurrence information transmitted from the relay means 300 to the security company or the police station 600 in real time by using the wireless network to quickly cope with illegal invasion or the like.

The server means 400 can be set to transmit only to the security company or only to the police station or to simultaneously transmit the security company and the police station according to the setting of the user.

The server means 400 may also be configured to transmit the abnormality information to the user smartphone 500 when the relay means 300 does not transmit abnormality information to the user smartphone 500.
