Description

[0001] The present invention relates to a child-resistant pest net touch-sensitive alarm system,

The present invention relates to a security system for a child protection screen.

Generally, when a window is opened in a window of an apartment or a single-family house, an insect screen is installed outside the window in order to block insects from entering the room from the outside. The insect screen is usually made of a metal wire, Or may be installed in a fixed state.

The above-mentioned insect screen has a separate locking device, so if the window is opened, the insect screen can be opened as it is. Using a knife to easily tear the screen screen and infiltrate into the house, Some homes are equipped with security windows to secure the outside of the screen.

However, although the above-mentioned security window can be effectively used for external infiltration and children's safety, there is a disadvantage that the escape route that can escape to the outside in the event of a fire or an emergency is blocked, There is a problem in that it has a feeling of being isolated from the outside by blocking the light and visibility of the outside view.

In addition, since the conventional insect screening simply acts to prevent the pest from entering the room, when the force is applied to the insect screen, the net easily tears. In the case of the apartment, when the child plays on the veranda and leans against the insect screen, The child is torn because it can not endure the accident, and the accident occurs.

The insect control net 100 is a metal net installed in a window or a veranda, and is formed of a metal net made of a conductive material. The net is used for insect pest prevention and crime prevention, and is installed for the safety of a child.

The detection warning means 200 is provided on one side of the insect-proofing net 100 in a clip or a press-fitting manner to sense a human body contacting the insecting net 100 and provide a warning voice or a warning alarm, And simultaneously generates human body contact detection information.

To this end, the sensing and warning means 200 can be configured in two ways, one of which is divided into an impedance sensing type and a capacitance sensing type.

First, the impedance-sensing detection and warning means 200 will be described.

And a communication unit (280) for transmitting the sensing information to the relay means (300).

The impedance sensing unit 210 senses a human body in contact with the insect control network 100 and senses a change in impedance generated when a human body contacts the insect control network 100. [

In the present invention, there are a current sensing method and a voltage sensing method as a method of detecting impedance change of an insect control net.

First, the current sensing method will be described.

The impedance sensing unit 210 includes a contact terminal 211 electrically connected to the insect control network 100 and a current sensing unit 212 sensing a current flowing through the inspecting network through the contact terminal.

That is, the contact terminal 211 is provided for electrical connection between the insect-proofing network 100 and the detection warning means 200. The contact terminal 211 is formed of two contact terminals, (Rated voltage) is applied, a current flows through the insect-proof net 100.

When a current flows through the insect control network, the current sensing unit 212 senses a current value flowing through the insect control network.

At this time, there may be a plurality of positions at which the two contact terminals make electrical connection with the screening net, and two points (P1, P2 or P3, P4 in FIG. 6) where the two contact terminals and the screening net are electrically connected are preferably as far apart as possible. The reason is that as the electrical connection points are farther away from each other, the impedance change detection becomes more accurate. Fig. 6 illustrates 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.

The current sensing unit 212 of the impedance sensing unit 210 senses a current flowing to the insecting net through the contact terminal 211.

When a voltage is applied to the insect-proofing net 100 through the contact terminal 211 by the power of the power source unit 270, a current flows through the insect-insecting net, which is a conductor.

At this time, the impedance (resistance value) of the insect control network is a preset value. More specifically, the impedance (resistance value) value of the insect control network is inputted through the impedance information input unit 230. Since the insect control network has different physical sizes depending on the place where it is used, the user inputs the impedance value of the insect control network through the impedance information input unit.

Therefore, in the normal case, the current value (meaning the rated current) flowing by the applied voltage (meaning the voltage of the power supply unit) is constant and can be known in advance.

However, the impedance of the insectproof room is changed by the various impedances of the insect screen due to various causes (human contact, change of the surrounding environment such as snow, boiling, etc.). At this time, the current value (sense current) changes. That is, when the current value flowing through the net screen is changed, the total impedance of the screen net changes, which means that the human body touches the net screen and the surrounding environment changes due to snow, rain, and the like. At this time, the impedance sensing unit senses a changed current value according to the impedance change of the insect control network.

For example, if the current value is 1 A, and the current value is changed to 0.8 A, then the total impedance of the insecticide will be the cause (human contact or environmental change ). ≪ / RTI >

The determination unit 220 determines whether a change in the current value sensed through the impedance sensing unit 210 is an impedance change due to a contact of the human body or a change in impedance of the living environment such as insect, rain, snow, , And the current change rate of the following equation (2).

[Equation 1]

Rated current = (the screen net impedance value input by the user through the rated voltage / impedance information input unit)

(At this time, rated voltage: power supply voltage)

&Quot; (2) "

Current change rate = (rated current / sense current)

(At this time, the sense current: the current value sensed by the impedance sensing part)

The impedance of the insect net depends on the physical size of the insect net, which varies depending on the location and location where the insect net is used. Therefore, the impedance value of the insect screen currently used by the user is input to the detection warning means 200 through the impedance information input unit in advance.

The determination unit 220 calculates the rated current value using Equation 1 based on the rated voltage and the impedance value of the screening network input through the impedance information input unit, and calculates the rate of current change using Equation (2).

And determines whether the calculated 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 no human contact or a change in living environment such as a pest, rain, or snow. An abnormal impedance change means a change in impedance due to human contact such as a child.

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 .

The controller 220 generates a control signal and provides the generated control signal to the speaker 250 and the sensed information generator 270. [

Next, the detection of the change of the screen netting impedance by the voltage sensing method will be explained.

In this case, the impedance sensing unit 210 includes a contact terminal 211 electrically connected to the insect-proofing net 100 and to which an applied voltage is applied, and a voltage sensing unit 213 measuring a sensed voltage according to an impedance change of the insecting net .

That is, the contact terminal 211 is provided to apply the applied voltage to the insecting network through the electrical connection between the insect control network 100 and the detection warning means 200. The contact terminal 211 is formed of two contact terminals, The voltage of the power supply unit 270 is applied to a specific point (for example, the points P1 and P2 in FIG. 7) of the screen.

When the applied voltage is applied to the insecting net, the sensing voltage corresponding to the impedance change of the insecting net is measured by the voltage sensing unit 213 connected to another point (for example, the points P3 and P4 in FIG. 7) of the insecting net.

7) and two other points electrically connected to the voltage sensing part 213 (for example, points P3 and P4 in FIG. 7), which are electrically connected to the contact terminal, ).

The two contact terminals 211 may be electrically connected to the insect control network in various positions, and two points where the two contact terminals and the insecting net are electrically connected are preferably as far as the distance 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 213 is electrically connected to the insect control network 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 power source voltage of the power source unit 270 is applied to the insect-protection net 100 through the contact terminal 211, the voltage sensing unit 213 measures the sensing voltage.

At this time, the impedance (resistance value) of the insect control network is a preset value. More specifically, the impedance (resistance value) value of the insect control network is inputted through the impedance information input unit 230.

Since the insect control network has different physical sizes depending on the place where it is used, the impedance value of the insect control network to be used is input through the impedance information input unit.

In the normal case where there is no change in the surrounding environment such as contact with the human body, eyes, rain, etc., the sensing voltage (hereinafter referred to as the rated sensing voltage) measured by the voltage sensing unit is constant due to the applied voltage (It can be known by measuring the test sense voltage beforehand under normal conditions)

However, the impedance of the insectproof room changes due to various causes (such as human contact or changes in the surrounding environment). At this time, the sensing voltage measured by the voltage sensing unit has a different value from the rated sensing voltage, which is a sensing voltage in a normal situation.

That is, if the sensing voltage measured by the voltage sensing unit is measured at a value different from the rated sensing voltage, it means that the overall impedance of the screening network has changed, which means that the human body touches the screening network and the ambient environment changes due to snow, rain, .

For example, when the sensed voltage measured by the voltage sensing unit 213 is 100V in a normal case (no change in human body contact or surrounding environment), the sensed voltage measured by the voltage sensing unit at a certain point of time is not 100V , It means that the total impedance of the screen net is changed by some cause (human contact or change of surrounding environment).

The determination unit 220 determines whether a change in the current value sensed through the impedance sensing unit 210 is an impedance change due to a contact of the human body or a change in impedance of the living environment such as insect, rain, snow, , And the voltage change rate of the following equation 4 is used.

&Quot; (4) "

Voltage change rate = (rated sensing voltage / sensing voltage)

(At this time, the rated sensing voltage: the voltage measured in the voltage sensing part under normal conditions

  Detection voltage: Voltage measured by the voltage detection unit in case of human contact or living environment change)

The impedance of the insect net depends on the physical size of the insect net, which varies depending on the location and location where the insect net is used. Therefore, the impedance value of the insect screen currently used by the user is input to the detection warning means 200 through the impedance information input unit in advance.

The determination unit 220 calculates the voltage change rate according to Equation (3) and determines whether the calculated total 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 no human contact or a change in living environment such as a pest, rain, or snow. An abnormal impedance change means a change in impedance due to human contact such as a child.

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 to be normal, and when the current change rate is less than 0.8, and when the voltage change rate is more than 1.2, it is determined to be abnormal.

The determination unit 220 provides a control signal to the speaker 250 and the sensed information generator 270 when the impedance changes abnormally.

The impedance information input unit 230 is for inputting the intrinsic impedance value of the insect control network 100 currently used by the user. The intrinsic impedance of the insect control network has different values depending on the size and the like, and the size of the insect control network used in each home The user inputs the intrinsic impedance value of the insect net used by the user through the impedance information input unit 230 in advance, and the intrinsic impedance value of the insect net inputted is used for calculating the rated current value.

When the human body touches the insect control network 100, the warning alarm storage unit 240 provides a warning voice or warning alarm through the speaker 250 formed at one side of the detection warning unit 200, Or a warning alarm sound is stored.

The warning message may be "dangerous", "withdraw", "do not approach", etc., and the warning alarm sound may be "siren or whistling sound".

When the plurality of detection warning means 200 are installed, the unique information of the detection warning means may be further stored in the warning alarm storage unit 240.

As a result of the determination by the determination unit 220, in the case of an abnormal impedance change due to human touch, the speaker 250 receives a control signal from the determination unit.

The speaker 250 receiving the control signal is formed at one side of the detection warning means 200 so as to provide a warning voice or a warning alarm and the warning voice or warning alarm may be either a warning voice or a warning alarm And a warning sound and a warning alarm can be provided in a complex manner.

The power supply unit 260 supplies a voltage for flowing current to the insect-proofing net 100 through the contact terminal 211 and supplies operating power to the sense warning unit 200.

The power supply unit 260 may be built in a battery type or may be supplied with external power.

The sensing information generation unit 270 counts the number of times the control signal is transmitted from the determination unit 220 and generates the total number of counts as the human touching frequency information.

Also, the contact time information is generated by grasping the time when the control signal is transmitted.

The sensing information generating unit 270 generates sensing information using the generated human touching frequency information and time information.

The sensing information may be generated in the form of "10: 43 _ 1 "," 13: 23 _ 4 ", or the like.

2, when the detection warning unit 200 is installed in the plurality of insect-proofing networks 100, the detection information transmitted to the relay unit 300 includes unique information of the detection warning unit 200 Lt; / RTI > The unique information may be a unique number of the detection warning means 200.

In this case, the detection information can be generated in the form of "detection alerting device unique number _ contact time _ contact count", for example, "01 _ 15: 30 _ 2", "03 _ 20:20 _ 1" .

In the above, the identification number of the detection warning means may be designated, for example, as a veranda for 01, 02 for a house window, 03 for a small window window, and the like.

The sensing information generated by the sensing information generating unit 270 may include contact statistical information indicating a contact frequency at a predetermined time interval.

The contact statistical information may include information on the number of contact by time interval. In this case, the contact statistical information may be generated in the form of "time interval_number of contact times ", for example, 07-10_5, 10-13_3, 13-16_10, Statistical information is generated and provided.

The time interval in the contact statistical information can be arbitrarily set according to the setting of the user.

The generated sensing information is transmitted to the relay unit 300 through the communication unit 280.

Next, the capacitance sensing sensing warning means 200 will be described.

As shown in FIG. 5, the capacitance sensing sensing and warning means 200

A capacitance sensing unit 215 sensing a capacitance change of the insect-proofing network 100;

Determining whether the capacitance change is a change due to a contact of a human body, a change due to a living environment change such as a pest, an eye, a rain, etc., and providing a control signal to a speaker and a sensing information generating unit when a change in capacitance is caused by human touch A determination unit 220;

A capacitance information input unit 235 for inputting a capacitance value of the screen guard 100 according to the size of the screen guard 100;

A warning alarm storage unit 240 for storing a warning voice message or a warning alarm sound for use in providing a warning voice or a warning alarm through the speaker 250;

A speaker 250 for providing a warning sound or a warning alarm when the change of capacitance is caused by the contact of the human body by the determination unit 220;

A power supply unit 260 for supplying power for sensing the capacitance of the capacitance sensing unit 215 and operation power for the sensing and warning means 200;

A sensed information generating unit 270 for generating sensed information including contact time information on the number of times of capacitance change due to human touch and contact time information as time information on the capacitance change;

And a communication unit (280) for transmitting the sensing information to the relay means (300).

The electrostatic capacity sensing unit 215 senses the electrostatic capacity of the insect-inspected network 100 when the human body is contacted and senses the contact of the human body. The capacitance sensing unit 215 senses a change in electrostatic capacitance generated when a human body touches the insect- .

The capacitance sensing unit 215 includes a contact terminal 216 electrically connected to the inspecting net 100.

The contact terminal 216 is formed to measure the capacitance of the screening net 100 and is formed of two contact terminals, one contact terminal is electrically connected to the network extinction and the other contact terminal is grounded. In this case, when a voltage is applied between the two contact terminals, the capacitance value between the insect net and the ground can be calculated. And the voltage applied between the two contact terminals is supplied from the power supply unit.

At this time, the capacitance sensing unit 215 senses the capacitance value between the insecting network and the ground.

The capacitance value (hereinafter referred to as the rated capacitance value) between the insecting net and the ground in a normal case (when there is no change in human contact or living environment) is a value that can be known in advance since it is determined as a unique value. In the normal case, the electrostatic capacity value between the insecting net and the ground is input to the sensing and warning means 200 by the user in advance through the electrostatic capacity information input unit.

However, the capacitance of the insectproof room is changed by various causes (such as human contact or changes in the surrounding environment).

For example, if the capacitance value is 1F (Ferredei) in the normal case (no change in human contact or the surrounding environment), if the capacitance value is changed to 1.2F for some reason, This means that an abnormal situation in which a substance or object is in contact (human contact or changes in the surrounding environment) has occurred.

The capacitance sensing unit 215 provides the sensed capacitance value (sensed electrostatic capacitance value) to the determination unit.

The determination unit 220 determines whether a change in capacitance due to contact with a human body or a change in capacitance due to a change in living environment such as rain or snow is detected using the capacitance value sensed through the capacitance sensing unit 215 And it is judged by using the electrostatic capacity rate of the following equation (5).

&Quot; (5) "

Capacitance change rate = (rated capacitance value / sensing capacitance value)

(The capacitance value of the insecticide network in the normal case input by the user through the capacitance input unit, the sensing capacitance value: the capacitance value of the insect control network sensed by the capacitance sensing unit 215)

The capacitance of an insect net depends on the physical size (area) of the insect net, which varies depending on the location and location where the insect net is used. Therefore, the capacitance value in the normal case of the insect control network currently used by the user can be known in advance and input to the detection warning means 200 through the capacitance information input unit 235.

The determination unit 220 calculates the capacitance change rate using Equation (3) based on the rated capacitance value of the insect control network input through the capacitance information input unit and the sensed capacitance value sensed by the capacitance sensing unit 215 do.

And determines whether the calculated capacitance change rate is within a predetermined change rate. As a result of the determination, if it is within the preset change rate, it is determined that the normal capacitance change is abnormal, and if it exceeds the predetermined change rate, it is determined that the abnormal capacitance change is abnormal.

A normal capacitance change means a change in capacitance due to no contact with a human body, a change in living environment such as a pest, rain, snow, etc. An abnormal capacitance change means a change in capacitance due to contact of a human body such as a child.

The predetermined rate of change is a value that can be arbitrarily set by a user, and is preferably 1 to 1.2.

For example, when the capacitance change rate is between 1 and 1.2, it is determined to be normal, and when the capacitance change rate exceeds 1.2, it is determined to be abnormal.

Generally, when a substance having a dielectric constant different from air such as a human body, insect pest, or eye is brought into contact with an insect screen, capacitance increases.

In general, the dielectric constant of rain and snow is larger than that of air, and the permittivity of human body is larger than that of rain and snow. Therefore, It is largely detected when human contact is made.

The controller 220 transmits a control signal to the speaker 250 and transmits the control signal to the sensing information generator 270. [

The electrostatic capacity information input unit 235 is for inputting a unique electrostatic capacitance value of the insect control network 100 currently used by the user (represented by the rated electrostatic capacitance value in the present invention) The size of the insect screen used in each home is different, and the user can know the intrinsic capacitance value of the insect screen used by himself / herself beforehand, and then the capacitance information input unit 235, And the intrinsic capacitance value of the input screen net is used for calculating the capacitance change rate.

When the human body touches the insect control network 100, the warning alarm storage unit 240 provides a warning voice or warning alarm through the speaker 250 formed at one side of the detection warning unit 200, Or a warning alarm sound is stored.

The warning message may be "dangerous", "withdraw", "do not approach", etc., and the warning alarm sound may be "siren or whistling sound".

As a result of the determination by the determination unit 220, the speaker 250 receives a control signal from the determination unit in the case of an abnormal capacitance change due to human body contact.

The speaker 250 receiving the control signal is formed at one side of the detection warning means 200 so as to provide a warning voice or a warning alarm and the warning voice or warning alarm may be either a warning voice or a warning alarm And a warning sound and a warning alarm can be provided in a complex manner.

Also, the power supply unit 260 supplies power for sensing the capacitance of the capacitance sensing unit 215 and operation power for the sensing / warning means 200.

The power supply unit 260 may be built in a battery type or may be supplied with external power.

The sensing information generation unit 270 counts the number of times the control signal is transmitted from the determination unit 220 and generates the total number of counts as the human touching frequency information.

Also, the contact time information is generated by grasping the time when the control signal is transmitted.

The sensing information generating unit 270 generates sensing information using the generated human touching frequency information and contact time information.

The sensing information may be generated in the form of "10: 43 _ 1 "," 13: 23 _ 4 ", or the like.

2, when the detection warning unit 200 is installed in the plurality of insect-proofing networks 100, the detection information transmitted to the relay unit 300 includes unique information of the detection warning unit 200 Lt; / RTI > At this time, the unique information may be the unique number of the detection warning unit 200.
