Windows security devices and systems

The present invention relates to a window security device and system, specifically, by using a motion detection sensor to simultaneously detect the inside and the outside of the window to detect the external intrusion by the signal detected from inside and outside, and furthermore, the presence of residents in the space area being managed The present invention relates to a window security device and a system for automatically detecting and reflecting an external intrusion detection.

Apartments, homes, and offices are spaces that have a variety of assets and are used by users with legitimate rights. Such spaces are often subject to external crimes because they hold a lot of assets of property value.

Various types of security devices or inventions are known as a countermeasure against crime. Such security devices are generally installed in general windows, veranda windows and the like. In addition, security devices must prevent crime through external intrusions and at the same time do not compromise the function of windows.

As a security device for windows, the most common form is a magnet switch attached to the window and the frame so that an alarm sounds when the window is opened. Since the security device should always be closed, the effectiveness of the security device is inferior when the window is frequently opened and closed.

As another method, a device is known that locks a window so that the window does not open from the outside. As an example of such a method, a "push-button window lock device" disclosed in Republic of Korea Patent Publication No. 10-0716026 (published on May 08, 2007) is known. In this way, you can open the window to some extent and no longer open it, but there are limitations to opening the window only to the point that no one can enter it from the outside.

It will be easy to implement. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing an exemplary block diagram of the window security apparatus 200. The window security apparatus 200 may be implemented in various modifications. 1 is a block diagram illustrating various modifications of the window security apparatus 200. Therefore, according to the modified example, the specific block of FIG. 1 may be omitted. For example, the window security apparatus 200 may not include the variable sensor module 220, and thus the external interface unit 216 may be omitted. Alternatively, the window security apparatus 200 may omit the user storage unit 214. In addition, the window security apparatus 200 may further include other blocks not shown in FIG. For example, the window security apparatus 200 may further include an input interface for receiving a user input or an output interface for outputting a response or a status according to the input.

Referring to the window security apparatus 200 through FIG. 1, the window security apparatus 200 includes a fixed sensor module 210 and further includes a variable sensor module 220. Fixed sensor module 210 is fixed to the window is installed. For example, the fixed sensor module 210 may be fixedly installed on the window frame outside the glass window. The fixed sensor module 210 detects a moving object inside or outside.

The fixed sensor module 210 may include an external detector 211, an internal detector 212, a short range wireless communication unit 213, a user storage unit 214, a sensitivity controller 215, an external interface unit 216, and a sensor. The control unit 217 is included.

Looking at each block of the fixed sensor module 210, the external detection unit 211 detects a moving object outside the window (glass window) on which the window security device 200 (especially the fixed sensor module 210) is installed.

The internal detection unit 212 detects a moving object inside the window in which the window security device 200 (especially the fixed sensor module 210) is installed. The outer detecting unit 211 and the inner detecting unit 212 are preferably provided with a sensor that can detect the movement of the human body. For example, the external detector 211 and the internal detector 212 may be configured or implemented as one or more sensors of an infrared sensor, a pyroelectric infrared (PIR) sensor, an ultrasonic proximity sensor, and a microwave proximity sensor.

The external detector 211 and the internal detector 212 are configured to detect the presence of a detectable moving object (preferably a human body) in its sensor detection area and output a detection signal. The detection signal indicates a signal value measured by the sensor or a signal value generated when the sensor detects a human body or the like.

Here, the sensor detection area (range) may be adjusted in size. In particular, the sensor detection area of the internal detection unit 212 can be reduced or regained by adjusting the detection sensitivity.

The short range wireless communication unit 213 enables transmission and reception of wireless data with the mobile terminal and / or the security center apparatus 100. The short range wireless communication unit 213 includes an antenna for transmitting and receiving a radio signal, a communication chipset or a communication module for modulating and demodulating the radio signal.

The short range wireless communication unit 213 is configured to wirelessly transmit and receive data through a designated wireless communication protocol. For example, the short range wireless communication unit 213 may transmit and receive wireless data with the mobile terminal or the security center device 100 through one or more standard protocols of Wi-Fi, Zigbee, and Bluetooth.

The short range wireless communication unit 213 may receive an identifier of the mobile terminal or a control signal from the mobile terminal from the mobile terminal. The mobile terminal may be a mobile phone, a smart phone, a tablet PC, or the like or a remote control configured for the system. Such an identifier, a control signal (control signal from a remote control, etc.) is transmitted to the sensor controller 217, and the sensor controller 217 can perform various controls accordingly.

Alternatively, the short range wireless communication unit 213 may receive control data from the crime prevention center device 100. The control data is data for controlling the window security apparatus 200, and is particularly used to adjust the detection sensitivity of the internal detection unit 212. The control data is generated when an authorized user enters into the managed space area or when no authorized user exists in the managed space area. The former control data requires reducing the detection sensitivity of the internal detection unit 212 and the latter control data is the data requiring the detection sensitivity of the internal detection unit 212 to be restored to the originally set (default) detection sensitivity.

As described above, the short range wireless communication unit 213 transmits and receives wireless data with the mobile terminal or wireless data with the security center apparatus 100 using the provided wireless antenna.

The user storage unit 214 stores user information using the window security apparatus 200. The user storage unit 214 is configured of a non-volatile memory or the like and stores data for authenticating an authorized user. For example, the user storage unit 214 stores an identifier (eg, a MAC address) of each mobile terminal of one or more users, and / or stores a password or the like that can be received through a remote controller or the like. User storage 214 may be omitted, depending on implementation. For example, when the short range wireless communication unit 213 receives control data from the security center apparatus 100, the user storage unit 214 can be omitted.

The external interface unit 216 is a block for interfacing with the variable sensor module 220 which may be further provided in the window security apparatus 200. The external interface unit 216 may be connected to the variable sensor module 220 by providing one or more connection terminals. The external interface unit 216 enables input of a sensing signal from the connected variable sensor module 220 to the sensor controller 217.

The sensitivity adjusting unit 215 adjusts the detection sensitivity of the internal detection unit 212. The sensitivity controller 215 is connected to the sensor controller 217 and adjusts the sensing sensitivity of the internal detector 212 according to the control of the sensor controller 217. For example, the sensitivity controller 215 may increase or decrease the sensor sensitivity of the internal detector 212 by using a variable resistor or a plurality of resistors that can be variably selected. In particular, the sensitivity control unit 215 is configured to reduce or reduce the detection sensitivity when there is an authorized user in the managed space area to prevent or reduce the malfunction by the internal user. In addition, if the user does not exist, the sensitivity adjusting unit 215 resets the detection sensitivity to the originally set detection sensitivity so that the intrusion through not only the window but also the entrance may be known.

The sensor controller 217 monitors and controls the blocks of the window security apparatus 200. The sensor controller 217 monitors and controls other blocks by circuit logic or program code. Preferably, the sensor controller 217 is provided with an execution unit capable of executing program code therein and controls the blocks by execution of the program by the execution unit. The sensor controller 217 may be implemented with, for example, a CPU, an MPU, a microcomputer, a controller, or the like.

The sensor controller 217 is configured to respond to various external situations by using program code. In particular, the sensor controller 217 is connected to the external detection unit 211 and the internal detection unit 212 to recognize a detection signal of the moving object and detects an external intrusion using one or more of these detection signals. Depending on the detection result, a sound signal or a light signal may be output (not shown) or data indicating the detection result may be output through the short range wireless communication unit 213.

Various controls performed by the sensor controller 217 will be described in more detail below.

2 is a view showing an embodiment of the window security device 200, Figure 3 is a view showing an example in which the window security device 200 is installed in the window. 2 and 3 are diagrams showing an implementation example and an installation example of the fixed sensor module 210 preferably having a PIR element.

As can be seen through FIGS. 2 and 3, the external detector 211 and the internal detector 212 of the fixed sensor module 210 are configured or include a PIR. The outer detection unit 211 is located in the direction of the glass window, which is the window outward direction to detect the moving object, and the inner detection unit 212 is located in the inner direction of the window to detect the moving object inside. The PIR device detects infrared rays from the human body, not the absolute amount of infrared rays, but the amount of change in infrared rays.

Therefore, when an external intruder or house insider approaches or moves away from the PIR device, the PIR device of the external detection unit 211 or the internal detection unit 212 outputs a response signal according to the detection of the amount of change in the infrared to the sensor controller 217.

PIR devices are sensitive to infrared rays from the human body, but they react sensitively to sudden changes in the sun or ambient temperature, causing malfunctions and failing to distinguish external intruders from insiders. Therefore, there is a need to provide a fixed sensor module 210 that prevents malfunction while using the PIR element, and enables the insider and outsider to distinguish the house, and further, the inside of the house can be sensed when the insider of the house goes out. This will be described in detail below.

The variable sensor module 220, which may be further included in the window security device 200, is connected to the fixed sensor module 210 and outputs a detection signal due to movement or intrusion of a window to the fixed sensor module 210.

The variable sensor module 220 includes one or more posture detection units 221 to output a detection signal indicating a posture or a change in posture to the fixed sensor module 210. The detection signal is transmitted to the sensor control unit 217 through the external interface unit 216 of the fixed sensor module 210, and the sensor control unit 217 can detect an external intrusion using the received detection signal.

The posture detection unit 221 is configured to detect an external intrusion even when the installed window is open. The posture detection unit 221 outputs a detection signal for identifying the posture of the posture detection unit 221 so that the sensor control unit 217 detects the posture change, or the posture detection unit 221 directly relates to the posture change. It may be configured to output a sensing signal (hereinafter, the description of one method may represent the description of another method).

The posture detector 221 may be implemented by, for example, a combination of a gyro sensor or one or more inclination switches. The inclination switch may be a contact output varies according to the inclination of the inclination switch, the combination of the inclination switch is composed of a plurality of inclination switches, and each inclination switch is a specified angle (for example, 10 degrees, 30 degrees, 50 degrees , 70 degrees, 90 degrees, etc.) may be to produce a contact output toggled.

External intrusion detection through the posture detection unit 221 will also be described in detail with reference to FIGS. 6 to 8.

4 is a diagram illustrating an exemplary system of a window security system configured through one embodiment of the window security device 200.

According to FIG. 4, the window security system includes at least one window security device 200 and a security center device 100, and the window security device 200 and the security center device 100 perform short-range wireless communication through a short-range wireless network. can do.

Short-range wireless communication is achieved using, for example, one or more standard protocols of Wi-Fi, Zigbee, and Bluetooth.

According to the present invention, the window security device 200 may independently detect an external intrusion or may be detected in connection with the security center device 100. In case of detecting external intrusion independently, the short range wireless communication unit 213 of the window security apparatus 200 performs wireless data communication with an authorized mobile terminal in the installed spatial area and independently using the user storage unit 214. It performs external intrusion detection and various settings.

If the security center device 100 further includes an external intrusion detection, the short-range wireless communication unit 213 of the window security device 200 may transmit and receive data to and from the security center device 100 through short-range wireless communication. Various settings can be performed according to the received data. In this case, the user storage unit 214 may be omitted.

Referring back to FIG. 4, when looking at the external intrusion detection associated with the crime prevention center device 100 in more detail, the crime prevention center device 100 permits access in a spatial area where a short distance wireless communication interface and the system are installed. A storage medium (eg, non-volatile memory or a hard disk) for storing a list of identifiers of users and storing programs, and a processor capable of executing a program.

The processor loads and executes a program of a storage medium. The processor transmits the control data to the window security apparatus 200 through a short range wireless communication by performing a stored program. The control data indicates whether there is a mobile terminal of an authorized user in a space area managed by the security system or data for controlling one or more window security devices 200 according to whether an authorized user exists in the space area. to be. The control data is, for example, data for controlling the sensitivity adjusting unit 215 provided in the window security apparatus 200, and is data for reducing the sensing sensitivity of the sensitivity adjusting unit 215 below the current sensitivity or increasing the current sensitivity.

In more detail, the processor periodically transmits wireless data through short-range wireless communication, receives wireless data of the mobile terminal in response thereto, and recognizes (extracts) the identifier of the mobile terminal from the wireless data. The identifier of the mobile terminal represents a MAC address, for example.

The processor stores the recognized identifier on the storage medium and further compares it with the list of identifiers previously stored on the storage medium. If the recognized identifier is present in the identifier list, the processor stores the recognized time and recognized identifier on the storage medium and increments the number of authorized users in the space area.

Upon recognizing the identifier of the authorized mobile terminal, the processor generates control data for controlling one or more window security devices 200 connected through short-range wireless communication, and generates the control data for each window security device through short-range wireless communication. Send to 200. The transmitted control data is transmitted to all window security apparatus 200. The control data may be, for example, data for reducing the sensing sensitivity of the sensitivity adjusting unit 215 of the window security apparatus 200. According to the reception of the control data, the sensor control unit 217 of the window security device 200 is configured to control the sensitivity adjusting unit 215 to reduce the detection sensitivity of the internal detection unit 212.

On the other hand, the processor is configured to receive radio data from the periodically recognized mobile terminal and recognize an identifier of the authorized mobile terminal. The corresponding recognition time is updated according to the recognition of the identifier of the mobile terminal. However, if the identifier of the mobile terminal is not recognized (unrecognized) through short-range wireless communication for a certain time (for example, 1 minute, 5 minutes, etc.) after the recognition time, the processor goes out of the spatial area managed by the mobile terminal. The number of authorized users existing in the current spatial domain is deducted first.

If the number of subtracted users becomes 0 (if no authorized user exists), the processor generates control data for controlling all window security devices 200 and uses the generated control data to close all windows through short range wireless communication. Transfer to the security device 200. The control data here is data which requires to restore or set the reduced sensing sensitivity to the original sensing sensitivity.

As described above, the present invention can reduce or increase the detection sensitivity of the internal detection unit 212. In particular, when a user is present in the room, the sensitivity may be automatically reduced to reduce malfunction due to various user actions or pets in the room.

Hereinafter, a control flow for detecting an external invasion according to a state in a space area that is managed by the window security system or the window security apparatus 200 of the present invention is shown in FIG. 1 (the window security apparatus 200) or FIG. 4 (the window security system). Reference to Figure 5 will be described using the drawings below.

(1) Entry of mobile terminal into space area

The window security device 200 or the security center device 100 (hereinafter referred to as 'device', if necessary, the name of each device explicitly) to enter a specific mobile terminal into the space area managed by the window security system. Recognize. For example, the

apparatus

100 or 200 periodically transmits wireless data through short-range wireless communication and receives wireless data (response data) accordingly. Wireless data may be referred to as a wireless signal.

The

apparatus

100 or 200 extracts an identifier of the mobile terminal from wireless data received through short-range wireless communication and compares the identifiers of the user list with the stored user list. When the mobile terminal of the authorized user is recognized according to the comparison result, the corresponding user identifier and the recognition time are recorded, and the

apparatus

100 or 200 updates the number of authorized users existing in the current spatial area.

The

apparatus

100 or 200 controls the sensitivity adjusting unit 215 according to the recognition of the user so as to reduce the detection sensitivity (range) of the internal detection unit 212.

As an example, the security center apparatus 100 receives wireless data according to transmission of wireless data through a communication interface and recognizes an identifier of a mobile terminal. The recognized identifier and recognition time are recorded on the storage medium and the number of authorized users in the space area is increased by one.

As the number of authorized users becomes one or more, the security center device 100 transmits control data to one or more (preferably all) window security devices 200 via near field communication. This control data is generated in accordance with the recognition of the identifier of the mobile terminal of the authorized user and is data for controlling the internal detection unit 212 of the window security apparatus 200. For example, this control data is data for requesting to reduce the sensitivity range of the detection sensitivity of the internal detection unit 212.

The sensor control unit 217 of each crime prevention center device 100 receives control data through the short range wireless communication unit 213 and controls the sensitivity adjusting unit 215 according to the received control data to sense the sensitivity of the internal detection unit 212. Decreases below the specified sensitivity range. Accordingly, when there is an authorized user, the detection sensitivity range for the internal detection is reduced, thereby reducing unnecessary malfunctions.

As another example, the sensor controller 217 of the window security apparatus 200 controls the short range wireless communication unit 213 to periodically transmit wireless data and receive wireless data indicating the response. The sensor controller 217 recognizes the identifier of the mobile terminal from the received wireless data and compares the recognized identifier of the mobile terminal with the identifiers stored in the user storage 214. If there is a matching identifier, the sensor controller 217 stores the identifier and the recognition time recognized in the nonvolatile memory of the user storage unit 214 and further updates the currently recognized number of users.

The sensor controller 217 controls the sensitivity adjusting unit 215 connected when the user identifies the presence on the space area being managed by at least one user according to the recognition of the identifier, thereby adjusting the detection sensitivity range of the internal detection unit 212. Reduce below the specified sensitivity range.

FIG. 5B is a diagram illustrating an example in which a sensing range is dynamically reduced according to the presence of an internal user. As can be seen in FIG. 5B, the detection range of the internal detection unit 212 is configured to be smaller than the original detection range according to the presence of the internal user.

(2) Entry of mobile terminal out of space

The

apparatus

100 or 200 may recognize the entry of a specific mobile terminal out of the space area managed by the window security system. For example, the

apparatus

100 or 200 periodically transmits wireless data through short-range wireless communication and periodically receives wireless data indicating a response from the mobile terminal. The

apparatus

100 or 200 recognizes the identifier of the mobile terminal from the wireless data and updates the recognized time.

The

apparatus

100 or 200 stores the mobile station identifiers currently recognized and the latest recognition time. Accordingly, a specific mobile terminal may be located outside the range of short-range wireless communication, and in this case, the

apparatus

100 or 200 may not recognize the mobile terminal.

If the identifier of the previously recognized mobile terminal is no longer recognized for a certain period of time, the

device

100 or 200 reduces the number of currently recognized users by the number of mobile terminals that are not recognized (generally 1) and further, the identifier of the mobile terminal. And the recognition time as past history data.

If all mobile terminal identifiers are no longer recognized, the device 100,200 updates the current recognized number of users to zero and controls the internal detection unit 212 to restore the range of detection sensitivity to the original specified sensitivity.

As an example, the security center apparatus 100 transmits wireless data and attempts to recognize an identifier of a mobile terminal. If the identifier of the mobile terminal currently recognized for a certain time cannot be recognized for a certain time after the recognition time, the recognition time corresponding to the identifier of the mobile terminal is stored as historical data and the number of authorized users is reduced by one.

As the number of authorized users becomes zero, the security center device 100 transmits control data to one or more (preferably all) window security devices 200 via near field communication. This control data is generated according to the identifier unrecognition of the mobile terminals of all authorized users and is data for controlling the internal detection unit 212 of the window security apparatus 200. For example, this control data is data for requesting to restore the sensitivity range of the detection sensitivity of the internal detection unit 212 to the original sensitivity range.

The sensor control unit 217 of each crime prevention center device 100 receives control data through the short range wireless communication unit 213 and controls the sensitivity adjusting unit 215 according to the received control data to sense the sensitivity of the internal detection unit 212. Restore to the specified sensitivity range. As a result, when no authorized user exists at all, the detection sensitivity range for internal detection is increased.

As another example, the sensor controller 217 of the window security apparatus 200 transmits wireless data through the short range wireless communication unit 213 and attempts to recognize an identifier of the mobile terminal. If the identifier of the mobile terminal currently recognized for a certain time cannot be recognized for a certain time after the recognition time, the recognition time corresponding to the identifier of the mobile terminal is stored as historical data and the number of authorized users is reduced by one.

As the number of authorized users becomes zero, the sensor controller 217 controls the sensitivity controller 215 to adjust the sensing sensitivity of the internal detector 212. For example, the sensor controller 217 controls the sensitivity controller 215 to restore the original detection sensitivity range, and the sensitivity controller 215 expands the sensitivity range of the internal detection unit 212 to the original range accordingly. .

Here, the sensitivity adjusting unit 215 has at least two sensitivity ranges, one sensitivity range is used when the user exists in the spatial domain, and the other sensitivity range is used when the user does not exist in the spatial domain. . The former sensitivity range has a relatively smaller range than the latter sensitivity range.

FIG. 5A illustrates an example in which the detection range is dynamically restored as there is no internal user. As shown in (a) of FIG. 5, as there is no internal user, the detection range of the internal detection unit 212 is restored to the original detection range.

(3) detection of external intrusions

External intrusions detectable by the present invention preferably indicate external intrusions through windows. The outside of the management area under management is not constant like the inside and is exposed to various environments. Outside, for example, includes the movement of non-human creatures such as birds, mice, and cats. The window security apparatus 200 or the window security system according to the present invention is configured to cope with various malfunctioning elements.

Hereinafter, the method of detecting an external intrusion when the user exists in the management area and when the user does not exist in the management area will be described. Furthermore, the method of detecting the external intrusion by using the posture detection unit will be further described.

1) If no user exists in the management area

When there is no user in the management area, the internal detection unit 212 is configured to detect the moving object with the original detection sensitivity (see FIG. 5A), and the two external detection unit 211 and the internal detection unit ( 212) to detect external intrusions.

For example, the sensor controller 217 receives a signal from the PIR element, which is the external detector 211, and determines whether the sensor is a detection signal by the moving object. If it is determined that the detection signal by the moving object according to a predetermined threshold value or the detected change amount, the sensor controller 217 moves through the external detection unit 211 to the volatile memory or nonvolatile memory that the fixed sensor module 210 may include. Record the object as detected. Thereafter, the sensor controller 217 receives a signal through the internal detection unit 212 and determines whether it is a detection signal by a moving object.

If the moving object is detected through the internal detection unit 212, the detection time of the detection signal recognition time of the internal detection unit 212 and the detection signal recognition time of the external detection unit 211 are compared to determine the recognition time of the internal detection unit 212. In the case of a time within a predetermined time period after the recognition time of the external detection unit 211, the sensor controller 217 may determine that an external intrusion has occurred and take various actions accordingly.

If the user does not exist, it is possible to detect the escape after the intrusion through the reverse direction detection. For example, the sensor controller 217 may recognize the detection signal through the external detection unit 211 within a predetermined time after recognizing the detection signal through the internal detection unit 212 to determine the escape route. The detection of such external intrusions and escapes may be stored in a nonvolatile memory of the fixed sensor module 210 and then used.

2) User exists in management area

In the case where a user exists in the management area, the internal detection unit 212 is set by the sensor control unit 217 to have a sensitivity range smaller than the original detection sensitivity (see FIG. 5B). Since the sensitivity range is reduced by the internal detection unit 212, malfunctions caused by arbitrary actions or the like by the user in the management area can be reduced.

Even when a user exists in the management area, the external intrusion is detected by using the two external detection units 211 and the internal detection unit 212.

For example, the sensor controller 217 may detect an external invasion by using a visual difference of recognition of moving objects of the two external detectors 211 and the internal detectors 212. The sensor controller 217 first detects the moving object through the external detection unit 211 and then detects the moving object through the internal detection unit 212 within a predetermined time period (range) to determine this sequential detection as an external intrusion. have.

In particular, the internal detection unit 212 is reduced in the sensitivity range according to the presence of the user. Accordingly, an intruder within the sensitivity range of the internal detection unit 212 entering through the window can be detected while preventing malfunction due to movement by the user inside.

In this manner, by using the two internal detectors 212 and the external detectors 211 (particularly two PIR elements), malfunctions can be reduced regardless of the presence of a user in the management area.

3) External intrusion detection method using the posture detection unit 221

On the other hand, when the management area (e.g., miscellaneous goods) is small or when pets and the like exist in the management area, malfunction may occur even when the sensitivity of the internal detection unit 212 is reduced. Therefore, in order to prevent malfunction or further to directly detect the intrusion by an external action, the external sensor may be further detected by using the variable sensor module 220 including the posture detection unit 221.

6 shows an example of the use of the window security device 200 further includes a variable sensor module 220, Figure 6 (a) shows an example for detecting an external intrusion using the variable sensor module 220 6B illustrates an example of not using the variable sensor module 220.

The variable sensor module 220 includes one or more posture detection units 221. The variable sensor module 220 may transmit a detection signal to the fixed sensor module 210 by connecting a connection connector to the fixed sensor module 210. The posture detection unit 221 may be installed in plurality depending on the size of the window.

The posture detection unit 221 is configured to detect a change in posture according to the opening, closing, or movement of the window or the movement of the flexible body 300, and transmitting the same to the fixed sensor module 210. For example, the attitude detector 221 may include an inclination switch or may include a gyro sensor.

The sensor control unit 217 receives a detection signal from the variable sensor module 220 through the external interface unit 216 and externally using the detection signal and the detection signal of the external detection unit 211 (or the internal detection unit 212). Intrusion can be detected.

7 is a diagram illustrating an example of detecting an external invasion using the posture detection unit 221. As can be seen from FIG. 7, when the sensor initial setting state of the posture detecting unit 221 is A (see FIG. 7A), an external intruder attempting to intrude cuts the flexible body 300 or (See FIG. 7B), the flexible body 300 can be moved (see FIG. 7C). Accordingly, the state of the posture detection unit 221 of the variable sensor module 220 is changed from A to B or C and the detection signal is transmitted to the fixed sensor module 210 through the connection connector.

The sensor controller 217 of the fixed sensor module 210 may receive a detection signal from the variable sensor module 220 through the external interface unit 216. When the sensor controller 217 uses only the detection signal of the variable sensor module 220, there is a possibility of malfunction.

In order to prevent a malfunction, first, the sensor controller 217 first detects a moving object through a detection signal through the external detector 211 and recognizes a detection signal through the variable sensor module 220 within a predetermined time range. Detect external intrusions by recognizing them as valid detections. Furthermore, the sensor controller 217 may detect a case where an intrusion occurs from the outside when the detection signal is recognized through the internal detection unit 212 after the detection of the detection signal indicating the inclination change through the variable sensor module 220. .

Through this entire sensor system, malfunctions can be reliably reduced and intruders can be detected whether or not windows are opened or closed.

FIG. 8 is a diagram illustrating another example of detecting an external intrusion using the posture detection unit 221, and illustrates an example of a state in which one end of the flexible body is attached to a movable window.

In the example of FIG. 8, the posture detection unit 221 of the variable sensor module 220 may detect a posture change according to the movement of the window and output the same. In the example of FIG. 8, the sensor controller 217 may first recognize a detection signal detected by the external detection unit 211, and then detect an external intrusion by recognizing a detection signal from the variable sensor module 220 indicating a posture change. .

As described above, the posture detection unit 221 may be further used to determine external intrusions without malfunction and to determine external intrusions under various situations.

If the user already exists in the spatial area, the detection sensitivity of the internal detection unit 212 is already reduced, thereby preventing malfunction. In addition, the sensor controller 217 may be configured not to recognize the recognition of the detection signal through the posture detection unit 221 as an external intrusion after the detection of the detection signal through the internal detection unit 212 when the user is present. .

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.
