Description

  The present invention relates to an indoor facility, and particularly relates to a crime prevention system suitable for security at home, in which an intruder detection device for crime prevention is arranged in a lighting device.

  Human body detection sensors used in conventional security are mainly magnet type sensors installed in window frames of window sashes and entrance doors, and detect the state of windows or doors by changes in magnetism generated by a magnetic circuit. It was a thing. However, with such a sensor, an intruder senses the installation of the sensor in advance, performs an action that does not generate a detection signal, or detects the state of an intruder indoor when it breaks through the spot There are issues that cannot be done.

  Therefore, pyroelectric sensors are attracting attention in order to detect the human body inside the room. Since this sensor detects the amount of infrared rays emitted by the human body, it can always monitor the presence or absence of an intruder. However, since this sensor also detects infrared rays emitted from a heat source such as a heater or a pet, it is often erroneously detected. For this reason, misdetected information is left to an external organization through a network, so an unnecessary security system is set, and unnecessary labor is required.

Accordingly, there is a need for a sensor that can identify a heat source, a pet, and the like, reliably detect only an intruder, and cannot easily recognize the presence of the sensor from the intruder, and sensing using a radio wave sensor is drawing attention. However, many of the conventional radio wave sensors are arranged at a position where an intruder can witness, and those that are concealed by building materials or window sashes or that are installed in a position where they cannot be seen from the outside are patented. It is only a reception antenna for public radio waves (mass media) described in Documents 1 and 2, and no sensor has been proposed as a security equipment sensor for human body detection.
JP 2004-228608 A JP 7-176924 A

  The present invention has been made to solve the above-described problems, and the problem of the present invention is that there is no false detection by a pet kept indoors, and it is possible to prevent an intruder from entering and exiting from the outside, the inside doorway, and the indoor space. It constitutes a human body detection sensor for crime prevention that can detect an operation.

  In order to achieve the above object, an invention according to claim 1 is an illuminating device including radio wave transmitting means and radio wave receiving means, wherein the transmitting means and the receiving means are located at predetermined positions of the lighting device. Reception received by the receiving means when the radio waves from the transmitting means are radiated in a horizontal direction or downward toward a point or region having a predetermined height or more at a reference position in the room. An illumination device characterized in that the presence or absence of an intruder is identified based on signal intensity data.

Here, the reference position indicates an entrance or an entrance to the other space from the space where the radio wave sensor is placed.
In the present invention, the radio wave sensor is disposed inside a lighting device installed in a building material that divides a wall or ceiling adjacent to a room or a hallway next to the indoor, and the height at which the radio wave sensor is installed is Because it is set to avoid objects that are supposed to block radio waves such as household appliances and planting, desks and chairs attached to general indoors, radio waves are surely emitted to targets such as intruders be able to. Furthermore, it is an indoor reference position, for example, a point above a predetermined height in furniture where valuables such as entrances and exits to other spaces and safes are placed, and radiates radio waves so as to detect areas associated with radio wave directivity. Therefore, only intruders can be detected without detecting small animals such as non-human pets. In this way, the radio wave sensor does not detect the amount of infrared rays emitted from the heat source, but detects the movement of the human body based on the intensity data of the received signal using the Doppler effect. A device can be configured. In addition, because there is no lens such as a surveillance camera to detect the movement of people, the intruder detection device for crime prevention that does not give the impression that is seen even if there is a resident indoors and maintains privacy Can provide.

  In order to achieve the above object, a second aspect of the present invention is an illumination device comprising radio wave transmission means and radio wave reception means, wherein the transmission means and the reception means are located at predetermined positions of the illumination device. The reception when the radio wave from the transmitting means is radiated in a horizontal direction or downward toward a point or region at a predetermined height or higher at a reference position located at an entrance to the room. The lighting device is configured to identify the presence or absence of an intruder based on intensity data of a received signal detected by the means.

  In the present invention, a radio wave sensor is disposed inside a lighting device fixed to a building material used for a wall or ceiling that partitions another indoor space, and the height at which the radio wave sensor is installed may be placed on the front surface. It is set at a position that avoids indoor equipment with a certain level, radiates radio waves to the indoor entrance that will enter from the outside, and can detect intruders based on the intensity data of the received signal. Because it detects an area above a certain height, it can detect only intruders when a small animal such as a pet kept indoors approaches the entrance, and it can detect only intruders, and there is little false alarm. An object detection device can be configured. In addition, radio waves can be transmitted if part of the entrance is made of materials such as glass, wood, plastic, etc., so intruders who approach the outside (outdoor side) of the entrance can be detected in advance. Since it can be left in the owner or an external organization before the room is opened, a high security system can be configured.

  In order to achieve the above object, a third aspect of the present invention is an illumination device comprising a radio wave transmission means and a radio wave reception means, wherein the transmission means and the reception means are at predetermined positions of the illumination device. And a point or region having a predetermined height or higher at the first reference position in the room, and a predetermined height or higher at the second reference position located at the entrance to the room. The lighting device is configured to identify the presence or absence of an intruder based on the intensity data of the received signal detected by the receiving means when radiating in the horizontal direction or downward toward the point or area.

  In the present invention, the radio wave sensor is a wall that partitions other indoor spaces located at a height that avoids objects that are supposed to block radio waves such as home appliances, planting, desks, chairs, etc. Installed in the lighting device fixed to the building material that constitutes the ceiling and the predetermined height at the indoor reference position from the location and the predetermined height at the second reference position located at the entrance to the room Because only two intruders entering the indoor space where the radio wave sensor is installed can be reliably detected in the state of approaching the entrance, the security point is highly secure with little false alarms. An intruder detection apparatus can be configured.

  In order to achieve the above object, a fourth aspect of the present invention is an illumination device comprising radio wave switching means for switching a plurality of directions of radio waves transmitted from the transmission means.

  In the present invention, there is a radio wave direction varying means that can arbitrarily switch the direction of the radio wave emitted from the radio wave sensor. Even if the reference position is set in the two-dimensional or three-dimensional direction, it can be installed as a security sensor for all spaces with a single type of sensor even when installing in multiple spaces. Therefore, it is possible to construct a radio wave sensor that is highly probable and has few false detections, and thus a crime prevention intruder detection device with few false alarms.

  According to the present invention, the movement of a human body approaching a window or a human body existing indoors is detected, the detection area of the entrance / exit is set to a predetermined height from the floor surface, and the output signal of the sensor is used to detect the object. Since the size, speed, and movement trajectory are detected to distinguish between pets and intruders, it is possible to provide a crime prevention intruder detection apparatus with few false alarms. There is an effect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a crime prevention intruder detection apparatus according to the present invention will be described below in detail with reference to the drawings.
(Reference Example 1)
FIG. 1A is an external view of a first embodiment of the security intruder detection apparatus, FIG. 1B is a top view of FIG. 1A, and FIG. Is shown in FIG. FIG. 2 shows a first modification of the first embodiment. FIG. 2 (a) is an external view, FIG. 2 (b) is a top view of FIG. 2 (a), and FIG. Shown in 2 (c). Moreover, it is E view figure of Fig.2 (a), and the fixed state to the window sash of a radio wave sensor is shown in FIG.

  The indoor facility 1 is provided with a window frame 3 that is a movable part, a window sash 2 that is configured outside the window frame, and an outer frame 4. The window frame 3 and the glass 5 provided therein and the radio wave sensor 6 are included. The window sash 2 can be opened in the horizontal direction with respect to the floor via rails installed above and below the window frame. A radio wave sensor 6 is disposed inside the outer frame for detecting a human body, and a portion 4a facing an antenna (described later) that transmits and receives radio waves in the outer frame 4 is cut off. A controller (not shown) that determines the position, size, approach / distance, and movement of the human body from the signal output from the radio wave sensor 6 and outputs the determination result as an external output signal is also installed. Details of the structure of the radio wave sensor will be described later. If the radio wave sensor is concealed inside the window sash in this way so that it cannot be seen from the outside, not only can it be prevented from being seen by an intruder and obstructing the detection performance of the sensor, but the owner can be detected on a regular basis. It is preferable without receiving a sense of being. However, if a radio wave sensor can be placed at a blind spot due to the window frame or outer frame structure, it may be installed on the indoor side surface of the outer frame. Is not visible at all. Furthermore, in the case of interference with a curtain stopper or a roll curtain provided in the room, a remote control type that can be attached from the outer frame may be installed in a state that matches the interior.

  FIG. 4A is an external view of the radio wave sensor 6, FIG. 4B is a G view of FIG. 4A, and FIG. A block diagram of the radio wave sensor 6 and the controller 25 is shown in FIG. The radio wave sensor 6 includes an oscillating unit 11 that generates a high frequency, a transmission antenna that radiates the generated high frequency to the outside, a reception antenna that receives a signal returned from the reflected radio wave reflected on an object (here, a human body), A detector 12 that outputs the size or speed of an object from the signal to be transmitted and the received signal is configured. From the detection unit, an AC signal 15 for identifying the moving speed of the object and a DC signal 16 for identifying the phase interference state corresponding to the position where the object exists are output. In order to reduce the size of the sensor, the transmitting antenna and the receiving antenna are integrated in the present invention. (Hereinafter referred to as the integrated antenna 14). The oscillation unit 11 and the detection unit 12 of the radio wave sensor 6 are housed in a shield case 17, and another integrated antenna 18 is installed on the ceiling surface of the shield case 17. Therefore, the radio wave can be radiated forward or backward around the shield case 17. If this forward radiating portion is provided indoors and the backward radiating portion is provided outdoors, an intruder approaching the window sash and indoor movement after the intrusion can be detected with one sensor. In addition, the radiation of the electric wave indoors and outdoors is not limited to this method, and a part of the electric wave radiated indoors may be reflected using a reflective material made of a metal material, or a radio wave sensor is installed. Two sensors may be arranged as long as the space of the part can be secured. The integrated antenna 14 has a radio wave direction changing means 19 for changing the direction of the radio wave, and can be scanned so that the radio wave from the radio wave sensor installed in the window sash can be radiated to every corner in the room and outdoors near the window sash. . Note that this sensor uses the 10.5G band when emitting radio waves only indoors, and the 24.15G band may be selected when detecting the movement of a human body approaching a window outside. The controller 25 includes a signal processing unit 26 that captures a signal from the radio wave sensor 6, an arithmetic processing unit 27 that calculates the size, position, movement, and moving direction of the object based on information obtained by the signal processing unit, and an arithmetic processing unit 27. There is a radio wave direction setting means 28 for setting the direction of the radio wave to be radiated next based on the result. If the arithmetic processing unit 27 determines that an abnormal situation has occurred, it may contact the external organization directly via radio, telephone line, etc., or it may be used for crime prevention in each room indoors. The detection result of the object detection apparatus may be transferred to a centralized management box (home server) that collectively manages the information, and information may be transferred from the centralized management box to an external organization.

  Since the radio wave direction changing means 19 used in this example performs electric radio wave scanning, it can scan at high speed unlike radio wave scanning using a drive source with a motor, and can track the human body. Further, since the sensor is fixed without being rotated following the power source, the housing can be easily designed in the window sash and a small sensor can be realized. In addition, unlike a phased array antenna, which is commonly used for electrical radio wave scanning and used for military applications, the grounding or opening of a high-frequency current generated on the antenna is switched only by the switch 20 provided on the antenna. Since the phase of the arrayed integrated antenna 14 is changed and the radio wave finally radiated from the antenna is tilted, there is no restriction on the amount of high-frequency transmission and phase change required for the switch 20, and an inexpensive general-purpose switch Therefore, there is no need to route a power supply circuit for changing the phase, and a compact and integrated sensor can be realized. In the present invention, in the conventional test, the detection distance decreases due to the decrease in the output intensity due to the impedance mismatch at the time of switching compared to the conventional type, but due to the relationship between the phase amount and the current amount between the antennas. It has been found that radio waves can be tilted to a wide angle. Therefore, it has a radio wave variable angle (tilt angle with respect to the normal direction of the antenna: 40 degrees) that secures a distance (maximum 10 m) for detecting the human body facing the sensor installation surface, and can look over the entire room. If it is the size of each room in the home, the human body can be detected with one sensor. As described above, in the present invention, the electric radio wave scanning method which emphasizes the emission of radio waves at a wide angle and the proposal of a small integrated sensor is used, but the size of the space where the sensor is installed and the window where the sensor is fixed are used. When the structure of the sash or the development of a low-cost, small, high-performance switching element is made, it is not limited to this method, for example, phase control is performed by the feed circuit length between the oscillation unit and the integrated antenna, A variable capacitor may be used.

  Since the radio wave sensor 6 performs sensing using the Doppler effect in which a difference between the transmitted radio wave and the received radio wave is identified by the detection unit 12, the movement of the object can be detected directly. Therefore, in order to detect the Doppler signal with respect to the movement of the human body with maximum sensitivity, it is desirable that the three-dimensionally resolved vector components of the direction of the radio wave and the movement direction of the human body match or be opposite to each other. In addition, in the frequency band used, the dielectric constant of materials other than metal, such as wood, tile, and resin, which are building materials, is small, radio waves radiated or received from the transmitting / receiving antenna are transmitted, and human (water) has a high dielectric constant ( 60-80), it reflects. Therefore, if a part of the window sash is made of resin, only the movement of the human body can be detected in a completely hidden state. Thus, since the radio wave sensor detects a person, it does not make a false detection with respect to a heat source like a pyroelectric sensor. In addition, if the direction of the radio wave radiated from the antenna of the radio wave sensor is set so that it can be detected by a person approaching the window sash (window) or an intruder in the room, for example, when the former is detected, Can be intimidated by turning on or sounding a security buzzer, and the electromagnetic lock 21 with a drive source that only comes from the inside can be locked to prevent intrusion. It is also possible to indirectly notify the presence of a person, automatically lock the window sash from the outside, confine an intruder, and simultaneously notify the outside 22 via the network and leave it to a predetermined organization.

FIG. 6 is a diagram illustrating the direction of the radio wave, FIG. 7 is a diagram showing the strength and weighting of each radio wave when the radio wave is scanned inside the room, and an actual radio wave scanning method. A conceptual diagram of this is shown in FIG.
The directivity of the radio wave radiated from the radio wave sensor can be generally expressed as follows. In other words, the absolute gain Ga of the antenna, when the antenna effective area is A and the wavelength of the radio wave transmitted from the antenna is λ, the radiation intensity of the radio wave increases as the antenna area increases,
Ga = A × 4π / (λ × λ)
Further, there is a relationship of the following equation between the absolute gain Ga of the antenna and the directivity gain Gd, and the absolute gain of the antenna with negligible loss is equal to the directivity gain (gain with respect to the omnidirectional antenna). Determined by shape (directivity angle).
Ga = ηrad × Gd
Therefore, the directivity of the antenna depends on the area of the antenna. The greater the number of antennas arranged in an array, the narrower the directivity angle, and the smaller the antenna, the wider the directivity. Considering the size of the sensor placed on the window sash using a 10.5G band frequency and a substrate with a dielectric constant of 10 or less, the directivity angle radiated from the antenna is at most 30 degrees (antenna gain 12 dB) And does not have a narrow directivity like a photoelectric sensor. This will be described with reference to FIG. For convenience of explanation, the radio wave sensor is installed on the ceiling. Now, the radio wave sensor is set so that nine directions can be emitted into the room. FIGS. 6A to 6C are radiated in three directions, and can be radiated in three directions in the same way from the front of the picture to the back. When the direction of the radio wave is sequentially changed in this way, the radio wave is radiated in a direction having a predetermined spread, so that an area overlapping with the radio wave radiated adjacently occurs. Therefore, it is impossible to determine the exact location and size of the human body by identifying only the presence or absence of the detected signal change. Therefore, the weight shown in FIG. 7 is set. Fig. 7 (a) shows the area where radio waves radiated in 9 directions reach the floor. Fig. 7 (b) is obtained when the room is divided into 25 and there are intruders at each position. The intensity of the reflected signal is expressed, and a part reaching at least a certain intensity (here, 3) is color-coded. In addition, although the radio field intensity of 9 directions changes a little, the maximum radio field intensity is described as being constant. FIG. 7C shows the representative values of FIG. 7B. The size of the object is determined in FIG. 7B, and the position of the object is detected in FIG. 7C. I have to. Further, specific radio wave scanning is shown in FIG. 8, and the peripheral integrated antennas 14b, 14c, 14d and 14e are advanced in phase with respect to the five integrated antennas 14a in advance, and 14b and 14c are in phase. Since 14d and 14e are set to the same phase, normally, the balance in the left and right and up and down directions is maintained around the integrated antenna 14a, and radio waves are radiated vertically from the back of the paper surface of this picture. Next, when the switch placed on the integrated antenna 14b is turned on and a part of the antenna is connected to GND (grounded), the radio wave radiated from the 14b antenna disappears, and the phase balance in the vertical direction is disturbed. Since the phase of the antenna 14c disposed on the lower side of the integrated antenna 14a is advanced, the radio wave is tilted upward as shown in the figure. Similarly, the switch on the side on which the radio wave is desired to be tilted is turned on in any direction. Can tilt. If it is desired to bend in an oblique direction, for example, if it is desired to bend to the upper left, the switches on the integrated antennas 14b and 14e may be turned on. By using this radio wave scanning means, it is possible to divide the room direction into nine parts and radiate radio waves to the respective areas. Note that the angle of inclination of the radio wave can vary depending on the distance from the central antenna to the peripheral antenna and the location where the switch on the antenna is installed, so the position of the window sash where the radio wave sensor 6 is installed and the shape of the indoor space that radiates It is good to set according to.
Note that the direct current component of each reflected signal when radio waves are radiated to the entire room differs depending on the layout of the space in which the sensor is installed and the interior in the space. Therefore, the reflected signal changes as equipment attached to the room moves. Therefore, the DC component without a human body is always grasped, and the offset is adjusted so that the value becomes a constant initial value, for example, 1V. When an object enters the room, the amount of change from the initial value is reduced. Thus, the position and size of the human body can be detected.

  When the window sash is a sitting window, for example, when the window sash is at a predetermined height L1 from the floor as shown in FIG. 1C, furniture, home appliances, and planting are placed on the front of the radio sensor. Even if it is opened, it is possible to reach the opposite wall or entrance / exit of the room without blocking the emission of radio waves. Accordingly, the predetermined height L is preferably as high as possible. However, in the present invention, the height of the interior placed on the front surface of the window sash is set to 1 m or more. On the other hand, as shown in FIG. 1B, in the case of a window sash composed of a floor that can be moved to the outside, a home interior is not installed in front of the window sash, but a desk, chair, kotatsu, etc. Since there is a possibility that radio waves may be blocked by the incidental equipment in the room, it is still better to install at a height of 1 m or more. In order to detect the Doppler signal accompanying the movement of the human body with maximum sensitivity, the position where the moving direction X of the intruder of the window sash and the entrance / exit door coincides with the radiation direction Z of the radio wave as shown in FIG. A relationship is desirable.

Radio waves are radiated to a predetermined height L2 with the entrance / exit 23 located inside the room shown in FIGS. This predetermined height L2 is set so as to detect only an intruder without detecting small animals such as pets that are supposed to travel inside and outside the room during absence, and is set to 1 m in the present invention. When a small animal is not kept or when the height is small, the L2 may be set small, which can limit detection errors of an intruder. In addition, in the intruder who entered through the window sash 2 and the entrance / exit 23, in order to be able to catch the intruder reliably in the event of a detection error such as passing down with his face down, The radio wave direction varying means 19 is set. In addition, when there is an area in the room that is particularly desired to be monitored, an arbitrary place can be detected by storing it in a memory (not shown) for setting the radio wave direction in advance. However, the radiation direction of the radio wave is not limited, and the entire region may be sensed as long as the entire room can be detected.
In this way, when radio waves are emitted horizontally or downward from the predetermined height of the window sash 2 toward the predetermined height of the entrance / exit 23 which is the reference position inside the room, the movement of the pet is not detected. The movement of the intruder leaving can be detected, and a crime prevention system with few false alarms can be provided.
In general, since the directivity of radio waves is wider than that of a photoelectric sensor, it is preferable to set the reference position in the previous period in consideration of the spread of radio waves. For detection of objects in the space, the radio wave direction changing means scans radio waves inside the room and outputs the output intensity of each reflected signal reflected from the object, the detection area, the moving speed, and the movement of the object. Even if an intruder crawls on the floor and moves by searching for the pet's unique movements such as memorizing the trajectory and staying at a specific place, when searching for the size of the moving object and goods Differences between people and small animals can be detected by detecting changes in posture.

(Second modification)
FIG. 9 shows a second modification of the security intruder detection device. 9 (a) shows an external view, FIG. 9 (b) shows an upper view of FIG. 9 (a), FIG. 9 (c) shows a J view of FIG. 9 (a), and FIG. ) Is a K view of FIG.
The indoor facility 1 includes a window frame 3 that is a movable part, an outer frame 4, a first window sash 2 composed of the window frame and the outer frame, and a surface on which the first window sash 2 is installed. It is composed of a second window sash 8 installed on an adjacent surface, an entrance door 23 for moving to another room indoors, and a radio wave sensor 6 installed in the first window sash 2. Yes.

  As shown in FIG. 9C, the radio wave sensor 6 is installed at a predetermined height of 1 m or more from the floor as shown in FIG. 9C, and furniture, home appliances and planting are placed on the front side of the radio wave sensor. Even if it is opened, it is possible to reach the opposite wall or entrance / exit of the room without blocking the emission of radio waves. The radio wave radiated from the radio wave sensor 6 has a predetermined height L2 with the entrance / exit 23 shown in FIG. 9 (d) as a reference position and a second window sash 8 as shown in FIG. 9 (d). And a predetermined height L3 as a reference position and an outer frame 4b disposed in the vertical direction on the side where the radio wave sensor 6 of the first window sash 2 is not installed as shown in FIG. 9C. The radio wave direction varying means 19 is set so as to radiate at a height L4. The predetermined heights L2, L3, and L4 are set to 1 m or more so that only intruders are detected without detecting small animals such as pets as in the first embodiment. Thus, when radio waves are radiated toward the outer frame facing the radio wave sensor 6 of the first window sash and the second window sash 8, the radio waves have a predetermined directivity, and a part thereof is outside the first window sash. Because it is radiated or transmitted through the window glass of the second window sash and can directly detect the outside, an intruder from the outside can be detected before the intrusion. Can provide a crime prevention system that ensures the safety of the person. In the unlikely event that there is an intruder from the entrance of another space, the entrance / exit 23 is also detected, so that the intruder approaching the indoor facility 1 is reliably identified and detected from small animals such as pets. It is possible. The second window sash is a system that detects only an intruder when radiating toward the same height even if the second window sash is disposed from the floor surface where a person usually goes to the veranda or the like. Can be provided.

When radio waves are radiated toward a plurality of reference positions in this way, the radio wave scanning time may be set from the time that an intruder will pass through each reference position. For example, when alternately detecting the reference position of the outer frame 4b facing the outer frame on which the radio wave sensor of the first window sash is installed and the reference position of the indoor access port 23, the time for entering and exiting the door is 0. If the time to break through the window sash is 1 minute with respect to 5 seconds, the time to detect the door is 30 seconds, the time to detect the window sash is 0.3 seconds, and the radio waves are alternately transmitted at intervals of approximately 1/2. High-speed scanning is not necessary, as long as it is switched. This set time may be arbitrarily changed according to the form of the door or window sash, and the scanning direction may be varied depending on the number of doorways. In addition, since the detection near the entrance / exit is not intended to detect the human body at that location, but also to detect the approaching / separating state of the human body, it is desirable to identify with the AC signal from the detection unit. Since a filter 29 (FIG. 5 (b)) that removes a DC component is mounted on a circuit until the AC signal is generally taken out from the detector, the time constant is unsuitable for detection during high-speed radio wave scanning. . However, in this initial state, since the area to be detected is limited as described above, it can be easily detected. In addition, considering that the human body passing through the entrance / exit could not be detected, the radio wave direction was periodically switched so that the entire room could be looked over, and each DC signal could be used to check for intruder detection errors. good.
Next, when it is detected that the human body is approaching the doorway, the radio wave is scanned around the detected area toward the periphery, and the controller determines which direction the human body moves and how big it is. Identify. In this case, the DC intensity is mainly measured to detect the output intensity and to perform radio wave scanning at high speed). As a result of the identification, if it is determined to be illegal intrusion, the home appliance or lighting is turned on as described above to threaten, the automatic lock mechanism is set to the locking mode, or a notification is made to an external engine via an external output signal.

  As described above, the intrusion detection device for crime prevention using the radio wave sensor does not require resolution enough to identify an individual and can gently monitor the behavior of the human body. Even when activated, there is no seen image like a camera, and the owner's privacy can be maintained. Also, there is no complicated image processing like a camera, and skillfully using DC and AC signal measurement makes it possible to instantaneously and reliably determine the movement, size, and position of an intruder, and false alarms due to false detection of pets, etc. It is possible to oscillate a signal externally in real time. Also, depending on the selection of the material of the window sash, it can be completely concealed and the interior interior is not disturbed, and an act that is confirmed in advance by an intruder and disturbs the detection performance of the sensor can be prevented.

(Reference Example 2)
An external view of the second embodiment of the security intruder detection device is shown in FIG. 10A, FIG. 10B is an upper view of FIG. 10A, and FIG. The L view of a) is shown, and the M view of FIG. 10A is shown in FIG.

  The indoor facility 50 includes a wall 51 that partitions the outdoor and indoors, a wall 52 that surrounds adjacent rooms, a flooring 59, a ceiling material (not shown), a first window sash 57, 2 window sashes 54, an entrance door 58, and a radio wave sensor 56. The radio wave sensor 56 is configured inside the wall 51 in order to enter and exit the indoor facility 50 and detect the movement of the human body in the facility. A controller (not shown) that determines the position, size, approach / separation of the human body from the signal output from the radio wave sensor 56 and outputs the determination result as an external output signal is also installed. The configuration of the radio wave sensor 56, the principle of the radio wave direction switching means, and the signal processing are the same as those in the first embodiment, and are therefore omitted.

As shown in the figure, the sensor is arranged on the back side of the plate-shaped building material constituting the wall 51, that is, between the heat insulating material and the indoor side panel. The panel is made of resin or wood, and the wallpaper (paper is made of wood = pulp is a raw material) having a design property on the panel surface can transmit radio waves as described above. Even if it is arranged inside, an indoor human body can be detected. Since the present invention uses the electric radio wave direction varying means having the same configuration as in the first embodiment, a sensor is provided in a space-saving manner, and the entire space can be covered with one sensor. It is possible to minimize the amount of building materials to be cut out, and to propose a system that diverts conventional building materials and does not affect indoor interior.
In addition, the radio wave sensor 56 is installed such that a vector in which the moving direction X of the intruder of the window sash 57 entering and exiting the indoor facility and the entrance / exit door 58 and the radiation direction Z of the radio wave are decomposed in a three-dimensional direction is not orthogonal. Therefore, a Doppler signal output from the radio wave sensor 56 can be output, and a sensor system with high detection accuracy can be realized. As shown in FIG. 10C, the radio wave sensor 56 is installed at a predetermined height of 1 m or more from the floor as shown in FIG. 10C, and furniture, home appliances and planting are placed on the front side of the radio wave sensor. Even if it is opened, it is possible to reach the opposite wall or entrance / exit of the room without blocking the emission of radio waves. The radio wave has a predetermined height L5 from the floor surface with the entrance 58 shown in FIG. 10 (d) as the first reference position, and the second window sash 54 as shown in FIG. 10 (d). The radio wave direction varying means radiates to a predetermined height L6 as a reference position for the first window sash 57 and a predetermined height L7 using the first window sash 57 as a third reference position as shown in FIG. Is set. The predetermined heights L5, L6, and L7 are set to 1 m so that only intruders are detected without detecting small animals such as pets as in the first embodiment. As described above, when radio waves are emitted toward the first window sash 57 and the second window sash 54, the radio waves have a predetermined directivity, so that part of the radio waves are radiated to the outside of the first window sash, Because it can detect the outside directly through the window sash, it can detect the intruder from outside before intrusion, so provide a security system that ensures the safety of residents living in the indoor facility 50 can do. In the unlikely event that there is an intruder from the entrance of another space, the entrance / exit 58 is also detected, so that the intruder approaching the indoor facility 50 is reliably identified and detected from a small animal such as a pet. It is possible. In the present invention, the radio wave sensor 56 is installed on the wall 51 that divides the outdoors and indoors. However, the same applies to the case where the radio wave sensor 56 is installed on the wall 52 for turning around an adjacent room. The first and second window sashes and It is possible to detect an intruder with certainty by radiating toward a predetermined height with each of the entrances and exits as a reference position.

Example 1
FIG. 11A shows an external view of the third embodiment of the crime prevention intruder detection apparatus, and FIG. 11B shows a modification thereof.

  The indoor facility 60 includes a wall 61 that partitions the outdoors and indoors, a wall 62 for separating adjacent rooms, a flooring 63, a ceiling material 64, a window sash 65, an entrance door 66, and a radio wave sensor 67. It consists of and. The radio wave sensor 67 is configured inside the ceiling material 64 in order to enter and exit an indoor facility and detect the movement of a human body in the space in the facility. A controller (not shown) is also installed that determines the position, size, approach and separation of the human body from the signal output from the radio wave sensor, and outputs the determination result as an external output signal. Since the radio wave sensor configuration, the principle of radio wave direction switching means, and signal processing are the same as those in the first embodiment, the description thereof is omitted.

As shown in FIG. 11A, the radio wave sensor 67 is disposed inside or on the back surface of the ceiling material. Here, the ceiling material includes those in which a reinforcing material is applied to the top plate, and those in which soundproofing materials and heat insulating materials are integrated, and a metal member is not disposed on the front surface of the integrated antenna of the radio wave sensor. In general, since the top plate is made of resin or wood, it can transmit radio waves as described above. Therefore, an indoor human body can be detected even in a concealed state. Since the present invention uses the electric wave direction changing means as in the first embodiment, the entire space can be viewed with one sensor.
The radio wave sensor 67 has a window sash 65 entering and exiting the indoor facility and an intruder moving direction X of the entrance door 66 and a radio wave excitation direction (W-W direction in FIGS. 4B and 11A). They are installed in such a positional relationship that the vector components in the radio wave radiation direction Z match as much as possible or are opposite to each other as much as possible. Therefore, the Doppler signal output from the radio wave sensor 67 can be output efficiently, and the crime prevention has high detection accuracy. Intruder detection device can be realized. Further, the radio wave direction changing means causes the radio wave radiation direction to radiate a predetermined height L8 from the floor surface with the entrance door 66 as a reference and a predetermined height L9 with the window sash 65 as the second reference position. Since switching is performed, an intruder entering the indoor facility 60 can be detected in advance outside the window sash or the door, and a system with high crime prevention can be provided. Since the predetermined heights L8 and L9 are set to 1 m or more as in the first and second embodiments, only intruders can be detected without detecting small animals such as pets. Even if a part of the room is invaded, the entire area inside the room is detected by the radio wave direction changing means, so that a system that does not miss the intruder is possible. At that time, if the radiation direction of the radio wave is partially stopped so as not to detect the area within the oblique line in FIG. 11A, the intruder can be detected without detecting the pet or the like moving out of the room. As described above, there are various forms suitable for capturing the movement of the human body moving the window sash 65 and the door 66 depending on the design of the indoor facility. However, the place may be moved to an optimal form, and generally, as shown in FIG. 10 (b), since the lighting fixture 68 is installed in the approximate center of the indoor space, it is not limited to the ceiling material. It is preferable to configure a system in which a plurality of members are not disposed as much as possible on the front surface of the sensor, such as being disposed on the back side of the front protective cover 69 of the luminaire 68, so that the amount of radio wave radiation is not attenuated. When installing on the lighting member 68, since the life cycle is shorter than that of building materials, it is preferable to use a remote control type with high installation flexibility so that it can be removed and re-installed on the replaced lighting member. As a result, it is possible to focus on the position that the owner wants to manage.

(Reference Example 3)
FIG. 12A shows an external view of the fourth embodiment of the intruder detection device for crime prevention, and FIG. 12B shows an enlarged view seen from the indoor side of FIG. 12A.

  12, the entrance 71 has an entrance door 72, a first lock mechanism 73 that can be operated from inside and outside the door, a second lock mechanism 74 that can be locked only from the inside, and a space for attaching and detaching shoes. 75, a camera 76 that can visually recognize a visitor outside the door, and a radio wave sensor 77 for detecting the movement of the human body approaching the door are arranged inside the door. A controller (not shown) is also installed that determines the position, size, approach and separation of the human body from the signal output from the radio wave sensor, and outputs the determination result as an external output signal. Since the radio wave sensor configuration, the principle of radio wave direction switching means, and signal processing are the same as those in the first embodiment, the description thereof is omitted.

  As described above, since radio waves do not pass through the metal material, the front surface of the antenna of the sensor is made of a material other than the metal material. For example, it is a high-strength plastic material such as FRP. As a result, an approaching human body can be detected without being aware of the presence / absence of the radio wave sensor and the installation location from outside. In addition, the position immediately before the door is set as a reference position so as not to detect an intruder, a pet or a child, and a short height object is used as a reference position, and radio waves are emitted at a predetermined height L10, so that only adults can be identified. Is possible. The predetermined height L10 is set to 1 m or more. Further, since the installation position of the radio wave sensor is known for the house owner, the reflected signal becomes the maximum value by holding the hand in front of the sensor, and detection is possible. In addition, if the directivity of the radio wave sensor is extremely narrow and the DC component of the reflected signal has a number of pixels that can identify an individual, it is determined whether or not it is the owner according to the image recognition result. You may do it.

  As a result of the above, when it is detected that a human body other than the owner has approached the door and stopped, the surveillance camera 76 may be activated and used to identify the approaching human body. 79 may be threatened by turning it ON, or the second lock mechanism 74 may be locked using a drive source. Therefore, since the surveillance camera 76 is not operated at all times and is used only when the radio wave sensor 77 senses an abnormality, a low-power system and an intrusion detection device for crime prevention with high detection accuracy without false alarms are possible. Moreover, since the 2nd locking mechanism 74 which can be locked only from the inside while going out can be operated, it is possible to protect domestic equipment even when the worst forced breakthrough is likely to occur.

FIG. 13 shows a state in which the radio wave sensor 91 is configured in each room in the home. As described in the first embodiment to the fourth embodiment, the radio wave sensor 91 uses a window sash, a building material, lighting, and the like, and is provided for each room and entrance. In the corridor, a centralized management box 92 for instructing a detection signal of a radio wave sensor in each room and a radio wave scanning method is disposed. This centralized management box 92 is connected by a network (not shown) so that it can control home appliances such as lighting and air conditioning in each room and security equipment.
As described above, when the radio wave sensor 91 detects an intruder other than the pet or the owner, the information is once transferred to the central management box 92, and an instruction to operate the security equipment for the room where the intrusion has occurred from the central management box 92. It is programmed to transfer the information to an external organization such as a security company via a power line, telephone line, or radio at the same time (for example, operating and threatening an automatic lock mechanism, lighting, surveillance camera, or home appliance). In addition, when the owner exists in the home, the information is notified to the owner, such as turning on the home appliances in the existing space, turning on the lighting, and supporting the personally owned terminal. It is also possible to do. Further, the detection information may be transferred so that the owner can quickly make a determination even when the owner is out.
In addition, this system can be used not only to detect external intruders but also to grasp the behavior of elderly people and children. For example, elderly people lie for a long time in places other than the bedroom while they are away. If you transfer information to people who are away from home, or if you are distracted by housework and lose sight of your child's behavior, you may want to use the water in the bathtub in advance if you are likely to move freely, such as in a bathroom or veranda. The window sash leading to the veranda may be automatically locked, or notification may be made using home appliances adjacent to mothers and other related parties.
Furthermore, it may be used not only for safe and safe use but also for energy saving control of equipment. The biggest feature of radio wave sensors is that people's movements can be understood. For example, the amount of change in the AC signal of a radio wave sensor is measured for a person in the living room. The illuminance may be reduced, or a home appliance such as a television may be turned off. In addition, by detecting the movement of people moving in the corridor, controlling the switching of the heater of the heated toilet seat in the toilet, you may lower or stop the warming temperature of what was conventionally kept warm, After detecting that a person has entered the dressing room, it is possible to eliminate wasteful heat dissipation by performing additional cooking control to make the bath water temperature a comfortable temperature. In addition to power saving, it is possible to propose a comfortable environment where people can act safely and easily without moving in the dark by previously controlling the lighting and air conditioning of the room where they move.
