Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that anticrime measures cannot be devised depending on various concrete situations brought about in actuality. <P>SOLUTION: A slat-type shutter device 61 is installed in a window section which makes the indoor and outdoor sides of a house 13 communicate with each other. A human detection sensor 34 for detecting a human on a surrounding site, and the shutter device 61 are connected to a home server 31. When the human is detected by the human detection sensor 34, a shutter control portion 76 controls a winding drive portion 68 so as to lower a shutter curtain, by a command of an equipment control portion 56 constituting the home server 31. In addition, similarly, the shutter control portion 76 controls a slat drive portion 73 so as to bring about the opening/closing motion of slats. The descending motion of the shutter curtain and the opening/closing motion of the slats are combined together, so that the anticrime measures can be devised depending on the concrete situations such as daytime or night time, the presence or absence of the human in a building, and which area to be invaded on the site. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a security system for security of buildings.

Various techniques have been proposed for crime prevention measures for buildings. As an example, a shutter device may be installed in an opening such as a window. In this case, a technique is known in which a shutter in a closed state is automatically lowered when a suspicious person approaching the shutter device is detected (see, for example, Patent Document 1). According to such a technique, the shutter can be prevented from being forcibly opened.
JP 2007-77791 A

  However, the specific situation in which a suspicious person tries to enter a building varies depending on the day, for example, during the day or at night, depending on whether there are people in the building or in which part of the site. For this reason, only when the suspicious person approaching is detected, the crime prevention measures are extremely limited only by lowering the shutter, and there is a problem that the crime prevention measures cannot be taken in accordance with various specific situations that occur in reality.

  Therefore, in view of such circumstances, the present invention considers a specific situation in which a suspicious person intends to enter a building, and implements a security measure suitable for the situation at the time to improve the security performance. The main purpose is to provide

  The present invention employs the following means in order to solve the above problems.

  That is, in the first invention, there is a security system for monitoring a building in which a slat shutter device is installed in an opening communicating indoors and outdoors, and an outdoor person detecting means for detecting a person on a site around the building; And a shutter control means for controlling at least one of a shutter curtain descending / closing operation and a slat opening / closing operation of the shutter device when a person is detected by the outdoor person detecting means.

  According to the first aspect of the invention, not only the shutter curtain lowering operation but also the slat opening / closing operation is used in combination with the shutter device control performed when a person is detected on the site. Is possible. Thereby, in consideration of a specific situation when a person is detected, it is possible to improve the crime prevention performance of the building by implementing a security measure suitable for the situation at that time.

  According to a second aspect of the invention, regarding the control of the shutter device, the outdoor person detecting means can detect the person so that the site can be divided into a plurality of areas and in which area of the site the person is detected. The shutter control means controls the shutter device on the condition that a person is detected in a predetermined area by the outdoor person detecting means.

  According to the second aspect of the present invention, the region in which the shutter device is controlled is limited, so that control in consideration of the region can be performed. For example, by setting a warning level in each area, it is possible to perform control only when a warning level is detected in a high area. As a result, the element of which area of the site is detected is added to the specific situation considered in the execution of the control, and more various controls can be performed.

  An example of an area with a low alert level is an approach area that includes an approach to a building entrance (eg, a house entrance). This is because the use frequency of people other than the building user is higher than in other areas. On the other hand, as an example of a region with a high alert level, there is a wall-side region provided so as to surround the building along the outer wall portion of the building. This is because the border area along the outer wall of the building is an area close to the building in the site, and the alert level against the suspicious person is higher than in other areas.

  Therefore, in the third invention, the predetermined area is an area excluding the approach area. According to the third aspect of the invention, since the shutter device is not controlled in an approach region where the frequency of use by a person other than the building user is higher than in other regions, unnecessary control is omitted and the usability of the system is improved. Can be made.

  In a fourth aspect of the present invention, when there are a plurality of shutter devices in the site, the predetermined region includes a region partitioned according to the installation location of each shutter device, and the shutter control means The above-described control is performed for the shutter device corresponding to the area in which the image is detected.

  According to the fourth aspect of the invention, the control is performed on the shutter device having the opening that is most likely to enter the building when a person is detected. For example, when there are a plurality of shutter devices in the site due to the fact that the building is built in the site or the building has a plurality of openings with the shutter device, depending on the size of the site, The risk of entering a building is not uniform across all openings. For this reason, an effective crime prevention measure can be implemented by controlling the shutter device corresponding to the area where the person is detected.

  In the fifth invention, even when the fourth invention is adopted, the predetermined area includes a wall-side area provided so as to surround the building along an outer wall portion of the building, and the shutter The control means performs the control for all the shutter devices when a person is detected in the wall area.

  According to the fifth aspect of the present invention, when a person is detected in an area where the alert level is higher in the site than in the other areas, such as the area near the wall, all the shutter devices are controlled. Thereby, the fall of crime prevention can be suppressed.

  Here, not only the above-described building crime prevention using the shutter device but also warning at the site itself can strengthen the crime prevention measures for the building. However, in the conventional site security system, only a warning with a high threatening effect (for example, a loud alarm buzzer) is prepared. For this reason, the system is operated only when warning of the site is particularly necessary (such as at night or when it is absent) to avoid inadvertent warnings. However, security measures on the site are not unnecessary when the system is inactive. For this reason, the conventional site security system has a problem that the crime prevention performance is insufficient.

  Therefore, in the sixth invention, the setting means for setting a warning level according to each area, and the person who is detected in a predetermined area by the outdoor detection means, the setting means is set in the setting means. Warning control means for executing warning control of the site according to the warning level of the area, and the warning of the site itself where the building is partly constructed is performed together with the warning of the building.

  According to the sixth aspect, when a person is detected in a predetermined area, the site's warning control according to the warning level set in the area is executed. That is, it is possible to eliminate the disproportionate warning control in the area where the person is detected in the warning of the site itself. As a result, it is possible to constantly monitor a suspicious person who intends to enter the site by operating the system at all times, and it is possible to surely enhance the crime prevention performance by combining the warning of the site itself.

  In order to embody this, it is preferable that outdoor person detecting means is installed in each area. This facilitates individual detection in each area. In addition, security control is executed in each area where a person is detected, that is, security means such as warning notification and photographing are installed in each area, and the warning control means controls the security means in the area where a person is detected. Thus, it is preferable to execute warning control according to the warning level of the area.

  In the seventh invention, when controlling the shutter device, the shutter control means does not receive the identification information from the portable communication device or does not match the identification information registered in advance even if it is received. As a condition, the shutter device is controlled.

  According to the seventh aspect of the present invention, when the building user enters the site, the portable communication device for transmitting the identification information is possessed by the building user and the identification information is registered in advance. Control of the shutter device can be prevented.

  In an eighth aspect of the invention, with respect to the control of the shutter device, an indoor person detecting means for detecting a person indoors in the building, and an activity state for determining whether the person detected by the indoor person detecting means is active or sleeping. And a time zone discriminating unit for discriminating whether it is a day time zone or a night time zone, and the shutter control unit is discriminated as a night time zone by the time zone discriminating unit, and The slats are opened on the condition that a person is detected by the indoor person detection means and further that the activity status determination means determines that the person is active.

  According to the eighth aspect of the present invention, if a person is present indoors at night time and the person is active, the slats of the shutter device in the state where the opening is closed are opened. Thus, when a person is indoors at night and the person is active, the lighting device installed in the building is normally lit. In such a situation where the lighting device is lit, light leaks to the outdoors by opening the slats. As a result, it is possible to make a suspicious person who has entered the site sense that there is a person indoors and prompt the user to leave the site.

  Note that, as a specific example of the activity status determination means, it is conceivable to determine using an indoor lighting status. This is because if the indoor lighting device is turned off or the illuminance is less than a predetermined value, it may be determined that the person is usually sleeping.

  In a ninth aspect of the invention, the apparatus further comprises indoor person detecting means for detecting a person indoors in the building, and time zone determining means for determining whether the time zone is daytime or nighttime, and the shutter control means The slats are opened on the condition that the time zone discriminating means discriminates the daytime time zone and the indoor person detecting means detects a person.

  According to the ninth aspect of the present invention, if a person is present indoors during the daytime, the slats of the shutter device are opened. Thereby, the presence of a suspicious person who has entered the site can be confirmed indoors.

  In a tenth aspect of the invention, the slat shutter device includes a slat opening / closing mechanism that opens and closes a part of the slats arranged above the opening of the building in the closed state of the opening. Only some of the slats that can be opened and closed are opened and closed.

  According to the tenth aspect of the invention, even if the slat is in the open state, the slat that is in the open state is a part (specifically, about several sheets) disposed in the upper part. In this case, since it becomes difficult for the suspicious person to reach the opened portion, the possibility of performing an illegal act such as destruction of the shutter device can be greatly reduced. Thereby, even when a slat is made into an open state, the fall of the high crime prevention performance obtained by installation of a shutter apparatus can be avoided.

  In an eleventh aspect of the invention, indoor person detecting means for detecting a person indoors in the building, activity status determining means for determining whether the person detected by the indoor person detecting means is active or sleeping, and daytime A time zone discrimination means for discriminating between a time zone and a night time zone, wherein the shutter control means is discriminated as a night time zone by the time zone discrimination means, and a person is detected by the indoor person detection means. The shutter curtain is lowered so that the opening is closed on the condition that it is detected and further that the activity status determination means determines that the person is sleeping.

  In the twelfth aspect of the invention, the shutter control further includes an indoor person detecting means for detecting a person inside the building, and a time zone determining means for discriminating between a daytime time zone and a night time zone. And means for lowering the shutter curtain to close the opening when the time zone discriminating means discriminates the time zone during the day and no person is detected by the indoor person detecting means. I tried to do it.

  According to the eleventh and twelfth aspects of the present invention, when the person in the building is sleeping at night time, or when there is no person in the day time, the opening of the building is automatically Closed. As a result, security measures by the shutter device are ensured.

  Embodiments will be described below with reference to the drawings.

[First Embodiment]
First, the site will be described with reference to FIG. As shown in FIG. 2, the site 11 is a south-facing land facing the public road R on the south side, and has a rectangular shape in plan view.

  Various structures are installed in the site 11. As typical ones, there are a boundary structure 12 and a house 13. The boundary structure 12 is installed in almost the entire area inside the boundary line with the adjacent land. The boundary structure 12 includes fences, fences such as block fences, wooden fences, etc., hedges, gates, vehicle entrance / exit gates, etc., which are suitable for the purpose of ensuring privacy, the preferences of the site owner, etc. A thing is appropriately selected and installed. In FIG. 2, the boundary structure 12 provided at the boundary with the south public road R is omitted. The house 13 is arranged from the west side (that is, from the northwest of the site 11) at the back of the south side entrance (boundary portion with the public road R). The house 13 (corresponding to a building) has a roof 14, and a entrance 15 is provided on the south side. The south side of the house 13 provided with the entrance 15 is the front (front) side. A window portion 17 (corresponding to an opening) that communicates indoors and outdoors is provided on the outer wall portion of the house 13.

  In the site 11, various spaces are provided in a portion excluding the building space of the house 13. Typical spaces include approach 21, parking space 22, garden space 23, side passage space 24, and the like. First, approach 21 is a passage space from a doorway (not shown) such as a gate installed at the boundary with public road R to entrance porch 16, where residents and visitors can walk between entrance 15 and public road R. It is mainly used when going back and forth. Since the entrance 15 of the house 13 is provided on the south side, the approach 21 is also provided in the front space extending to the south of the house 13. The parking space 22 is a space for parking the vehicle S, and a space sufficient for parking at least one vehicle (two in the present embodiment) S is secured. A parking space 22 is also provided in the front space of the house 13 so that the vehicle S can enter and leave the public road R. The garden space 23 is a space used by a resident for a variety of purposes (for example, entertainment, viewing, etc.), and is provided so as to extend from the front space of the house 13 to the inner space adjacent to the east side of the house 13. Garden trees T are planted in the garden space 23 in various places. The side passage space 24 is a space provided between the boundary structure 12 and the house 13, and is used as an installation space for a garbage storage area or various outdoor facilities (for example, an outdoor unit of an air conditioner), a parking space for a motorcycle, and the like. Is done. Since the house 13 is arranged from the northwest, the side passage space 24 is provided on the west side and the north side of the house 13.

  Next, in this embodiment, a building security system is applied to the house 13 built on the site 11. In installing this building security system, the site 11 is partitioned into a plurality of regions based on the above-described various spaces throughout the entire portion of the house 13 excluding the building space. The section here refers to a section assumed in the configuration of the building security system, and does not necessarily mean that the section is visually partitioned by a boundary object or the like. The plurality of areas will be described with reference to FIG. 3 which is a plan view of a site schematically showing the areas. Each region is partitioned by a straight boundary line in order to simplify the boundary. This is also convenient for installing the sensor when an intrusion into each area is detected by a human detection sensor, as will be described later. FIG. 3 also shows a state associated with a later-described stage area.

  As shown in FIG. 3, the portion of the site 11 excluding the residential building space is divided into four areas: an approach area A, a parking area B, a garden area C, and a wall-side area D. The boundary area D is set so as to surround the house 13 with a boundary line set at a predetermined distance (for example, about 1 m) from the outer wall portion of the house 13. The entrance porch 16, the neighborhood of the parking space 22 and the garden space 23, the side passage space 24, and the like are included in the wall area D. The approach area A is an introduction area including the approach 21 described above. The parking area B is an area obtained by removing the wall area D from the parking space 22, and the garden area C is an area obtained by removing the wall area D from the garden space 23.

  Next, this building security system has one feature in that it controls a shutter device installed in the window portion 17 of the house 13. Therefore, first, the configuration of the shutter device will be described below with reference to FIGS. 4 and 5. 4A is a side view of the window portion 17, and FIG. 4B is a front view of the window portion 17 viewed from the indoor side. FIG. 5 is a front view of the shutter device viewed from the outdoor side.

  First, the shutter device of the window portion 17 is originally installed as a security measure for preventing a suspicious person from entering the house 13 through the window portion 17. For this reason, a part necessary for crime prevention measures (for example, the window part 17 having a size that allows a person to pass through on the first floor) is selected from the window part 17 of the house 13 and the shutter device is installed. . Of course, the case where a shutter apparatus is installed in all the window parts 17 may be sufficient.

  As shown in FIG. 4A, the shutter device 61 is disposed on the outdoor side of the window portion 17, more specifically on the outside of the sash door device 18. The shutter device 61 includes a horizontally long box-shaped shutter case 62 and a shutter curtain 63 housed in the shutter case 62 in a wound state. The shutter case 62 is attached above the window portion 17, and the shutter curtain 63 is extended downward. The shutter curtain 63 is lowered by being drawn out from the shutter case 62, and is raised by being wound in the shutter case 62. That is, when the shutter curtain 63 is lowered, the shutter device 61 is closed, and at the same time, the window portion 17 is also closed. Further, when the shutter curtain 63 rises, the shutter device 61 is opened, and at the same time, the window portion 17 is also opened.

  As shown in FIG. 5, the shutter curtain 63 is a slat type shutter curtain having a plurality of slats 65, and each slat 65 is connected in the vertical direction. Each slat 65 is formed in the shape of a horizontally long plate, and is arranged so as to be lined up and down. The slats 65 are partly engaged with each other in the upper and lower adjacent slats, and are configured to rise and fall integrally. On the left and right sides of the shutter curtain 63, guide rails 66 for guiding the raising and lowering of the curtain 63 are installed. The guide rails 66 are attached to the left and right sides of the window portion 17. In addition, since the structure of the coupling connection of the slats 65 is well known, description by illustration is abbreviate | omitted here.

  The uppermost slat of the slats 65 is connected to a take-up drum 67 installed in the shutter case 62, and the take-up drum 67 rotates and winds and unwinds the shutter curtain 63. Is called. The winding drum 67 is rotated by driving a winding driving unit 68 including an electric motor or the like. Therefore, the shutter curtain 63 moves up and down as the winding drive unit 68 is driven, and the shutter device 61 (the window unit 17 at the same time) is opened and closed.

  A plurality of upper slats 65 (specifically, three) are configured to rotate around an axis extending in the horizontal direction. They can shift to an open state and a closed state by rotating. In the closed state, the short side of the slat 65 stands upright in the vertical direction, and in the open state, the slat 65 is inclined with respect to the closed state. Here, as shown in FIG. 4B, when the slat 65 is in the open state, a horizontally elongated vent 69 is formed between the slats 65 adjacent to each other in the vertical direction. The ventilation portion 69 extends along the long side of the slat 65 and forms a gap between the slats 65. For this reason, natural ventilation can be performed through the ventilation portion 69 even when the window portion 17 is closed by the shutter curtain 63. When adjacent slats 65 are in a closed state, no gap is formed between the slats 65, and even if there is a gap, the gap is extremely small.

  The guide rail 66 is provided with an opening / closing guide mechanism 71 (corresponding to a slat opening / closing mechanism) that opens and closes the upper three slats 65 in the shutter curtain 63. The opening / closing guide mechanism 71 has an engagement link portion 72 that can be engaged with a part of each slat 65. The engaging link portion 72 opens and closes the slats 65 by engaging and operating with the three upper slats 65. The open / close guide mechanism 71 includes a slat drive unit 73 that includes an electric motor or the like. When the slat drive part 73 is driven, the engagement link part 72 is operated, and the upper three slats 65 are opened and closed.

  Next, the detailed structure of a building security system is demonstrated, referring the block diagram shown in FIG. 1, and the data table of FIG.

  As shown in FIG. 1, the building security system 30 includes a home server 31 (corresponding to a shutter control unit, a time zone determination unit, and an activity status determination unit) installed indoors. The home server 31 is a computer including a CPU, RAM, ROM, and the like, and an operation unit 32 and a wireless communication unit 33 are connected to the home server 31. In addition to the human detection sensor 34 and the alarm device 35 installed outdoors, the home server 31 is connected to the shutter device 61, and the human detection sensor 38, the illuminance sensor 39, and the illumination device 81 installed indoors. .

  The operation unit 32 includes an operation element (for example, a button or a switch), and various input processes to the home server 31 are possible by operating an operation element assigned for each processing content. For example, the start of the operation | movement of the building security system 30 and its cancellation | release are received, or the change of the setting memorize | stored previously is received.

  The wireless communication unit 33 has a wireless communication function that enables wireless communication with a portable communication device (portable device) 36 that is carried by each resident or person permitted to enter the house 13. . With this wireless communication function, individual identification information (user ID) possessed by each portable device 36 can be transmitted to the home server 31. The portable device 36 is a small one that is not disturbed even if it is carried and is easy to keep. For example, an electronic key can be used as the portable device 36, a mobile phone that is used on a daily basis can be used as the portable device 36, or an IC card having a communication function can be used as the portable device 36.

  The outdoor human detection sensor 34 is a sensor for detecting a person (corresponding to an outdoor human detection means), and is, for example, a human sensor using infrared rays. One or more human detection sensors 34 are installed in each of the areas A to D of the site 11 (see FIG. 3). In this case, the boundary structure 12 and the outer wall of the house 13 are used, or a support such as a pole is newly installed. Note that the types, number of installations, and installation locations of the human detection sensors 34 have a blind spot (a portion that is not detected) in each of the regions A to D in consideration of all circumstances such as the size and shape of the regions A to D, and the situation of the adjacent land. It is appropriately selected so as not to occur. The human detection sensor 34 is assigned an identification number (sensor ID) for each of the installed areas A to D. For example, as shown in FIG. 6, the human detection sensor 34 in the approach area A is SE1, the human detection sensor 34 in the parking area B is SE2, the human detection sensor 34 in the garden area C is SE3, and the human detection sensor 34 in the wall area D. Is set to SE4. Therefore, when a person enters any of the areas A to D, the person is detected by the human detection sensor 34 installed in the area, and a detection signal including the sensor ID assigned to the sensor 34 is transmitted to the home server 31. Is done.

  The alarm device 35 is a device for notifying a warning, and is, for example, a speaker (audio output device), a light (illumination device) having a light emitter such as an LED, or the like. One or a plurality of alarm devices 35 are installed in a range set as the wall-side region D of the site 11 (see FIG. 3). In this case, the boundary structure 12 and the outer wall of the house 13 are used, or a support such as a pole is newly installed. It should be noted that the type, number of installations, and installation location of the alarm device 35 take into account all circumstances such as the width and size of the areas A to D, the situation of the adjacent area, etc., so that the warning can be effectively notified to the intruder. It is selected appropriately. In this embodiment, two types of devices, a speaker 41 and a light 46, are used as the alarm device 35. The speaker 41 outputs a warning signal (for example, a warning buzzer sound “Pee”) at a predetermined volume. The light 46 can be either blinking or extinguished.

  The lighting device 81 installed indoors is, for example, a fluorescent lamp or an incandescent lamp, and is installed in each room or hallway provided in the house 13. The lighting device 81 can be switched on or off by a resident's manual operation, and can also be switched by control of the home server 31.

  The indoor human detection sensor 38 is a sensor for detecting a person (corresponding to an indoor human detection means), and is, for example, a human sensor using infrared rays. The human detection sensor 38 is installed in each room or hallway provided in the house 13. The human detection information by the human detection sensor 38 is sequentially transmitted to the home server 31, whereby the home server 31 can grasp whether or not a resident exists in the house 13.

  The indoor illuminance sensor 39 is a sensor that detects the illuminance indoors, and is installed in each room or hallway of the house 13. The indoor illuminance information by the illuminance sensor 39 is sequentially transmitted to the home server 31, whereby the home server 31 grasps the illuminance in the house 13. Based on the illuminance information, the home server 31 grasps whether or not the resident is active. That is, the home server 31 determines that the resident is active when the indoor illuminance information acquired from the illuminance sensor 39 is greater than or equal to a predetermined value on the assumption that the resident is at home. If the user is sleeping, the illumination device 81 is darkened or turned off at night, and the illuminance becomes less than a predetermined value. For this reason, it becomes possible to judge whether a resident is active based on the illuminance in the house 13.

  In the building security system 30 having the above configuration, when a person enters any one of the areas A to D of the site 11, the home server 31 enters based on the sensor ID transmitted from the person detection sensor 34. Determine the area that was selected, and perform security operations. Specifically, the crime prevention operation is performed by the operation control of the shutter device 61 and the operation control of the alarm device 35.

  Therefore, the details of the home server 31 that manages the operation of such a system will be described. As shown in FIG. 1, the home server 31 includes a main control unit 51 that controls the building security system 30, a storage unit 52 that is connected to the main control unit 51, an authentication unit 53, and an area determination unit. 54, a device control unit 56 is provided.

  The storage unit 52 stores information such as a system control program and various databases, and has an area for temporarily storing various information (for example, flags) when the program is executed. Examples of the database stored in the storage unit 52 include a user ID base and an alarm database.

  As the control program, programs corresponding to the home mode, the absent mode, and the sleep mode are stored. The mode is shifted to any one of these modes, and the main control unit 51 executes processing corresponding to the shifted mode. Incidentally, the home mode is a mode that is set when the resident is at home in the house 13. The absent mode is a mode that is set when all residents have gone out and are away. The sleep mode is a mode that is set when the resident is sleeping at night.

  The user ID database stores user IDs permitted to stay in the areas A to D of the site 11. This user ID is stored in the database by a user registration process performed in advance. The registration process can be applied with a known existing technique, and thus the description thereof is omitted.

  The alarm database stores a data table related to alarms. FIG. 6 shows the data table. As shown in the figure, in this data table, a plurality of stage areas are set according to the alert level for the intruder. There are three stages: an access permission area with a low warning level, a warning area with a high warning level, and a warning area with an intermediate warning level. And each area | region AD of the site | part 11 is matched with any one stage area, and, thereby, each alert level is set. Specifically, the approach area A is set as an access permission level, the parking area B and the garden area C are set as a warning area, and the wall area D is set as a warning area (see FIG. 3). In approach area A, the frequency of entering by persons other than residents (visitors and the like) is high, and since the risk of a suspicious person entering the house 13 is low as long as the person stays in this area A, the alert level is set low. On the other hand, the wall-side area D is an area close to the house 13 in the site 11 and has a high risk level for entering the house 13, so the alert level is set high. The parking area B and the garden area C are resident-specific areas, but the distance from the house 13 is still secured to some extent, so an intermediate warning level between the approach area A and the wall-side area D is set.

  In FIG. 6, the identification information (sensor ID) of each of the areas A to D and the human detection sensor 34 installed in each area and the alarm content performed by the alarm device 35 are also tabulated.

  Returning to FIG. 1, the authentication unit 53, the area determination unit 54, and the device control unit 56 other than the storage unit 52 will be described. First, the authentication unit 53 performs user ID authentication processing according to an instruction from the main control unit 51. Here, when the human detection sensor 34 detects that a person has entered one of the areas A to D, whether or not there is a response by transmitting a request signal, Whether the user ID associated therewith matches the user ID information stored in the user ID database of the storage unit 52 is determined.

  The area determination unit 54 determines which area of a three-stage area a region in which a person has entered corresponds to an instruction from the main control unit 51. For the determination, a data table (see FIG. 6) stored in the alarm database of the storage unit 52 is used.

  The timer unit 55 has a clocking function synchronized with the current time, and the main control unit 51 determines whether the current time is the daytime or the nighttime time from the current time. When the current time is set, it can be considered as an example that the manual time is input by the resident. In addition, a more accurate time may be set by periodically receiving a standard radio wave.

  The device control unit 56 controls operations of various devices connected to the home server 31 based on instructions from the main control unit 51. In this embodiment, an alarm device 35, a shutter device 61, and a lighting device 81 are connected to the home server 31 as devices. For this reason, by the operation control of the device control unit 56, the alarm device 35 is notified of an alarm signal from the speaker 41 and the light 46 blinks. In the shutter device 61, the shutter control unit 76 that receives the control signal from the device control unit 56 controls the driving of the winding drive unit 68 or the slat drive unit 73. As a result, the shutter curtain 63 moves up and down, and the slats 65 are opened or closed. Furthermore, the lighting device 81 is switched on or off by the operation control by the device control unit 56.

  In addition, when controlling the shutter curtain 63 and the slat 65, it is necessary to grasp the position and the open / closed state thereof. For this reason, a curtain position sensor 77 and a slat state detection sensor 78 are connected to the shutter control unit 76, and information regarding the position information of the shutter curtain 63 and the opening / closing state of the slat 65 is obtained from each of the sensors 77 and 78.

  The above is the configuration of the building security system 30. Next, the operation of the building security system 30 executed by the main control unit 51 of the home server 31 will be described.

<Mode transition processing>
First, the mode transition process will be described with reference to FIG. 7 which is a flowchart showing the process. This mode transition process is performed by operating an operation element (for example, a start button) assigned to start security in the operation unit 32.

  In FIG. 7, in step S101, it is determined whether or not the user is at home. If the user is at home, that is, if a resident is detected by the indoor human detection sensor 38, the determination is affirmed and the process proceeds to step S102 to further determine whether or not the resident is active. If the resident is active, that is, if the illuminance information obtained from the illuminance sensor 37 is greater than or equal to a predetermined value, the determination is made that the resident is active and the home mode processing is started in step S103. Thereby, the building security system 30 shifts to the home mode.

  If the user is not at home in the previous step S101, the process proceeds to step S104 to start the absence mode process. Thereby, the building security system 30 shifts to the absence mode. If the resident is not active in step S102, that is, if the resident is sleeping, the process proceeds to step S105 to shift to the sleeping mode. Thereby, the building security system 30 shifts to the sleep mode.

  And after performing a home mode process, an absent mode process, and a sleep mode process, it returns to step S101 again.

<Each mode processing>
Next, processing in each mode will be described. Each of these mode processes includes a common process. For this reason, such common processes will be described together, and only different processes will be described individually for each mode process.

(Explanation of common processes)
FIG. 8 is a flowchart showing a process common to each mode process, and FIG. 9 is a flowchart of the authentication process in FIG. In FIG. 8, in step S <b> 201, it is determined whether or not a person is detected in the site 11 by the outdoor human detection sensor 34. When there is human detection, that is, when a sensor ID is received from the human detection sensor 34 because a person has entered one of the areas A to D, the determination is affirmed and the process proceeds to step S202. In step S202, it is determined whether or not an actor attribute flag is set. The actor attribute flag is set once the authentication process is executed, as will be described later. If it is not set, the determination is denied and the authentication process in step S203 is performed. On the other hand, when the actor attribute flag is already set, the determination is affirmed and the process proceeds to step S204 after the authentication process.

  Here, the authentication process will be described. In FIG. 9, a request signal transmission process is performed in step S301, and in a subsequent step S302, it is determined whether or not a user ID has been received in response to the request signal. If there is no response, that is, if the user ID has not been received, the process proceeds to step S306, the suspicious person flag is set, and the authentication process is terminated.

  On the other hand, if there is a response, that is, if a user ID is received, the process proceeds to step S303, and ID authentication is performed based on the received user ID. If the authentication is OK, that is, if the person who has entered the area has the portable device 36 that has been registered in advance, the determination in step S304 is affirmed and the process proceeds to the subsequent step S305. In step S305, an authorized person flag is set as a person who is permitted to enter the site 11, and the authentication process is terminated. On the other hand, in the case of authentication NG, that is, when the mobile device 36 is not registered, the determination in step S304 is denied and the process proceeds to step S306. After the suspicious person flag is set, this authentication process is terminated.

  Returning to FIG. 8, in step S204, it is determined whether or not the permitted person flag is set. When the suspicious person flag is set in the previous authentication process (step S203), the determination is denied and the process proceeds to step S205. On the other hand, if the permitted person flag is set, the determination is affirmed and the process is terminated. Therefore, a person who has a registered portable device 36 stays at the site 11 and does not carry out alarm processing or control of the shutter device 61 described later in any mode processing. repeat.

  In step S205, which proceeds when the suspicious person flag is set, it is determined to which stage area the area where the person has entered corresponds. When the received sensor ID is SE1, it is determined that the entry area is the approach area A and the stage area is the access permission area. When the sensor ID is SE2 or SE3, it is determined that the entry area is the parking area B or the garden area C and the stage area is a warning area. When the sensor ID is SE4, it is determined that the entry area is the wall area D and the stage area is a warning area.

  If the determined stage area is an access-permitted area, the determination in step S206 is affirmed and the process ends. For this reason, even if the suspicious person flag is set, if the entered area is the approach area A which is the access permission area, individual processing (alarm processing and control of the shutter device 61) in each mode described later is not performed. On the other hand, if the determined stage area is not an access permission area, that is, a warning area or a warning area, the determination in step S206 is denied and the process proceeds to step S207 to perform individual processing in each mode. Thereafter, this process is terminated.

  In the first step S201, if no person is detected, that is, if no person is present in any of the areas A to D, the determination is denied and the process proceeds to step S208. In step S208, it is determined whether or not the actor attribute flag set in the authentication process in step S203 described above is set. If the flag is not set, the determination is denied and the process is terminated. For this reason, if no person enters the site 11 and the actor attribute flag is not set, both determinations in step S201 and step S208 are denied, and the process ends. On the other hand, if no one has entered the site 11 but the actor attribute flag is set because a person has entered the site 11 immediately before, the determination in step S208 is affirmed, and in the subsequent step S209, the actor attribute flag is set. To reset. Thereafter, this process is terminated.

  Next, the individual processing in each mode in step S207 will be described.

(Home mode processing)
The individual processing in the home mode is shown in the flowchart of FIG. As shown in FIG. 10, first, alarm processing is performed in steps S401 to S404, and then shutter control processing is performed in steps S405 to S408.

  The alarm processing is as follows. In the first step S401, it is determined whether or not the stage area determined in the previous step S205 is a warning area. If it is a warning area (border area D), the determination is affirmed, and a warning operation corresponding to the time zone is performed for a person who has entered the warning area. That is, in the next step S402, it is determined whether or not the current time zone is during the day. If it is during the day, the determination is affirmed and a warning signal having a relatively large volume is output from the speaker 41 in the next step S403. Inform. If it is nighttime instead of daytime, the determination is denied, and the light 46 is blinked in the next step S404. Such warning signal notification and flashing lights intimidate those who have entered the warning area and encourage them to leave the site. The reason for changing the alarm contents according to the time zone is to consider the neighborhood. In other words, even if a warning signal with a relatively large volume is notified during the daytime, there is little risk of inconvenience in the vicinity, and it also leads to notification of the presence of a suspicious person. On the other hand, since the night time is a time when many people sleep, the lights are stopped from blinking so as not to bother the buzzer.

  If the step area determined in step S205 is a warning area (parking area B or garden area C), the determination in step S401 is denied and the process proceeds to the next shutter control process. Therefore, the alarm operation is performed only when entering the wall-side area D that is a warning area. When the detected area is the access permission area (approach area A), as described above, this individual mode process is not performed in the first place.

  The shutter control process following such an alarm process is as follows. In step S405, it is determined whether or not the shutter curtain 63 is raised. Here, when the shutter curtain 63 is at a position higher than the maximum lowering position at which the window portion 17 is completely closed, it is determined that the shutter curtain 63 has been raised. If it is raised, the determination is affirmed and the process proceeds to step S406, the drive of the winding drive unit 68 is controlled, and the shutter curtain 63 is lowered. Thereafter, the individual processing in the home mode is terminated.

  If the shutter curtain 63 is at the maximum lowered position, the determination in step S405 is denied and the process proceeds to step S407. In step S407, it is determined whether or not the upper three slats 65 are open. When the three slats 65 are in the open state, the determination is affirmed and the individual processing in the home mode is terminated. On the other hand, when the three slats 65 are in a closed state, determination is denied and it progresses to step S408. In step S408, the driving of the slat driving unit 73 is controlled to open the upper three slats 65. Thereafter, the individual processing in the home mode is terminated.

  As described above, in the home mode, if a suspicious person enters the approach area A, which is an access permission area, from the public road R, neither alarm processing nor control of the shutter device 61 is performed. When a suspicious person enters the parking area B or the garden area C that is a warning area and the wall-side area D that is a warning area, the operation of the shutter device 61 is controlled. By the control, the shutter curtain 63 is lowered to the maximum and the window portion 17 is closed. At the same time, the upper three slats 65 are opened. Through the vent 69 formed thereby, the state of the site 11 can be confirmed indoors if the intrusion time is during the daytime. Further, since the home mode is a mode in which the resident is active indoors, the indoor lighting device 81 is lit even in the night time zone. For this reason, if the time of invasion is a night time zone, the light of the illumination device 81 leaks outside through the ventilation portion 69. By doing so, a suspicious person who has entered the site 11 can be informed that there is a person in the house 13 and can be urged to leave the site 11. Furthermore, when the area where the suspicious person has entered is the wall-side area D, a warning by the alarm device 35 is also provided to urge the suspicious person to leave using sound, light, or the like.

(Absence mode processing)
The individual processing in the absent mode is shown in the flowchart of FIG. Even in the absence mode process, the alarm process is performed first, which is the same as the alarm process (steps S401 to S404) in the above-described home mode. That is, an alarm action (warning signal notification or blinking of a light) is performed when entering a wall-side area D that is a warning area. For this reason, the description of the alarm process is omitted.

  The subsequent shutter control process is as follows. In FIG. 11, it is determined in step S501 whether or not the shutter curtain 63 is raised. Here again, it is determined that the shutter curtain 63 is raised when it is in the raised position from the maximum lowered position. If it is raised, the determination is affirmed and the process proceeds to step S502, where the drive of the winding drive unit 68 is controlled to lower the shutter curtain 63. Thereafter, the individual processing in the home mode is terminated.

  If the shutter curtain 63 is at the maximum lowered position, the determination is negative in step S501 and the process proceeds to step S503. In step S503, it is determined whether the current time zone is daytime. If it is during the day, the determination is affirmed, and in the next step S504, it is determined whether or not the upper three slats 65 are open. If the three slats 65 are in the closed state, the determination is denied and the individual processing in this absent mode is terminated. On the other hand, when the three slats 65 are in an open state, determination is affirmed and it progresses to step S505. In step S505, the driving of the slat driving unit 73 is controlled to close the upper three slats 65. Thereafter, the individual processing in the home mode is terminated.

  If the current time zone is nighttime, the determination is denied in the previous step S503 and the process proceeds to the next step S506, where it is determined whether or not the upper three slats 65 are open. If the three slats 65 are in the closed state, the determination is denied, and in the next step S507, the driving of the slat driving unit 73 is controlled to open the upper three slats 65. On the other hand, if the three slats 65 are in the open state, the determination in step S506 is affirmed, and the process proceeds to the next step without performing the process of step S507. In subsequent step S508, the indoor lighting device 81 is turned on, and the individual processing in the absence mode is ended.

  As described above, in the absence mode, similarly to the above-described home mode, if the intrusion area is the approach area A, the alarm process and the operation control of the shutter device 61 are not performed. Further, if the parking area B and the garden area C, the operation control of the shutter device 61 is performed. If the wall area D, the alarm processing and the operation control of the shutter device 61 are performed together. However, regarding the control contents of the shutter device 61, the absence mode is slightly different from the home mode. That is, all the slats 65 are closed during the daytime period, while the upper three slats 65 are opened during the nighttime period, and the lighting device 81 is turned on. Thereby, the system which prevents that a suspicious person penetrate | invades in the house 13 from the window part 17 at the time of absence of the daytime is made. Further, when the person is absent at night, the light of the lighting device 81 is leaked outside through the ventilation portion 69, so that the suspicious person can misunderstand that he / she is at home and can be urged to leave the site 11.

(Sleeping mode processing)
The individual processing in the sleep mode is shown in the flowchart of FIG. The alarm process is first performed in the sleep mode process, which is the same as the alarm process in the home mode described above (steps S401 to S404). Therefore, the description of the alarm process is omitted here.

  The subsequent shutter control process is as follows. In FIG. 12, it is determined in step S601 whether or not the shutter curtain 63 is raised. Here again, it is determined that the shutter curtain 63 is raised when it is in the raised position from the maximum lowered position. If it is raised, the determination is affirmed and the process proceeds to step S602, where the drive of the winding drive unit 68 is controlled to lower the shutter curtain 63. Thereafter, the individual processing in this sleeping mode is terminated.

  If the shutter curtain 63 is at the maximum lowered position, the determination is denied in step S601 and the process proceeds to step S603. In step S603, it is determined whether the upper three slats 65 are in the open state. If the three slats 65 are in the closed state, the determination is denied and the individual processing in this sleeping mode is terminated. On the other hand, when the three slats 65 are in an open state, determination is affirmed and it progresses to step S604. In step S604, the driving of the slat drive unit 73 is controlled to close the upper three slats 65. Thereafter, the individual processing in this sleeping mode is terminated.

  As described above, in the sleeping mode, similarly to the above-described home mode, if the intrusion area is the approach area A, neither alarm processing nor operation control of the shutter device 61 is performed. Further, if the parking area B and the garden area C, the operation control of the shutter device 61 is performed. If the wall area D, the alarm processing and the operation control of the shutter device 61 are performed together. However, regarding the control of the shutter device 61, this sleeping mode is slightly different from the case of the home mode. That is, all the slats including the upper three are closed. Thereby, the system which protects a suspicious person invading into the house 13 from the window part 17 during sleep is made.

  In summary, according to the building security system 30 of this embodiment, the following advantageous effects can be obtained.

  When the intrusion of a suspicious person into the site 11 is detected, the specific situation at the time of the invasion (day or night, whether there is a resident, whether the resident is active, which area A to the site 11) The shutter device 61 is automatically controlled in consideration of whether it has entered D or the like, and security measures appropriate for the situation are taken. For this reason, the crime prevention performance of the house 13 can be improved.

  More specifically, when approaching the approach area A, the area A is an access permission area with a low alert level and the risk of entering the house 13 is still low. No action is taken. Thereby, careless operation control of the shutter device 61 can be avoided, and usability of the building security system 30 can be improved.

  When entering the other areas B to D, these areas are a warning area having an intermediate warning level or a warning area having a high warning level, and the risk of entering the house 13 is increased. For this reason, the operation control of the shutter device 61 is performed. In that case, the crime prevention performance can be enhanced by first lowering the shutter curtain 63 and closing the window portion 17. In particular, when the resident is sleeping at nighttime or when the resident is absent even during the daytime, the window portion 17 is automatically closed to ensure security measures. can do.

  If the resident is active indoors during the night time, the upper three slats 65 are opened. Thereby, the light of the illuminating device 81 can be leaked outdoors to make a suspicious person detect the presence of a resident and prompt the user to leave the site 11. On the other hand, even when a resident is present indoors during the daytime, the slat is in an open state. Thereby, presence of the suspicious person who invaded the site 11 can be confirmed from the indoor.

  Even when the suspicious person enters the site 11, even if the slats 65 are in the open state, only the upper three slats 65 are in the open state. Since the suspicious person is difficult to reach the ventilation portion 69 formed in the open state, the possibility of performing an illegal act such as destruction of the shutter device 61 can be greatly reduced. Thereby, even when the slats 65 are in the open state, it is possible to avoid a reduction in the high crime prevention performance obtained by installing the shutter device 61.

  A user ID registered in advance is stored in the storage unit 52 of the home server 31. When a person enters the site 11, the user ID is received from the portable device 36 or is registered even if it is received. It is determined whether the user ID matches. Only in the case of authentication NG, the operation control of the shutter device 61 is performed. For this reason, if the resident has the portable device 36 and the user ID is registered in advance, it is possible to prevent the shutter device 61 from being erroneously controlled when the resident enters the site 11.

[Second Embodiment]
In the above embodiment, the alarm device 35 is installed only in the wall-side area D, which is a warning area, and warning (warning signal notification and light blinking) is performed only when a suspicious person enters the area D. Instead, an alarm device 35 is installed in each of the areas A to D, and an alarm corresponding to the level of the alarm level of the area is notified from the alarm device 35 in the intruded area. Good. Thereby, not only the crime prevention using the shutter device 61 in the first embodiment but also the warning of the site 11 itself is performed, and it becomes possible to strengthen the crime prevention measures for the house 13.

  Hereinafter, the difference from the first embodiment will be mainly described with reference to FIGS. 13 and 14. FIG. 13 is a block diagram of the building security system in the second embodiment, and FIG. 14 is a data table of the alarm database.

  As shown in FIG. 13, in the building security system 90, one or a plurality of alarm devices 35 (security means) are installed in each area A to D of the site 11. As the alarm device 35, a speaker 41 and a light 46 are used.

  The speaker 41 includes a control unit 42, a storage unit 43, and an output unit 44. The control unit 42 controls the operation of the speaker 41. The storage unit 43 stores various audio contents corresponding to the required threat level. For example, in descending order of threatening effect, a non-permission signal (for example, a guidance signal indicating that “site is guarded”), a warning signal (for example, a guidance signal indicating “warning”), and “beep” Warning buzzer sound, etc.), a warning signal (for example, a warning buzzer sound such as “Pee”), and the like. One of these signals is selected by the control unit 42 and is output from the output unit 44 at a predetermined volume. The light 46 is composed of an indicator lamp or a red rotating lamp, and includes a light emitting unit 47 and a control unit 48 that controls the lighting thereof. The control unit 48 turns the indicator lamp on, flashes, or turns off, and turns the red rotating lamp on or off. For the light 46, either an indicator lamp or a red rotating lamp is selected for each of the areas A to D. Specifically, an indicator lamp is selected in the approach area A, the parking area B, and the garden area C, and a red rotating lamp is selected in the wall area D.

  The alarm device 35 is assigned an identification number (alarm device ID) for each of the installed areas A to D. For example, the speaker 41 in the approach area A is SP1, the speaker 41 in the parking area B is SP2, the speaker 41 in the garden area C is SP3, and the speaker 41 in the wall area D is SP4. The light (indicator light) 46 in the approach area A is LA1, the light (indicator light) 46 in the parking area B is LA2, the light (indicator light) 46 in the garden area C is LA3, and the light in the wall area D (red rotating light). ) 46 is a PA.

  As shown in FIG. 14, different alarm contents are set in each of the stage areas, ie, the access permission area, the warning area, and the warning area. As the alarm content, the operation content of the alarm device 35 described above is appropriately selected. Details are as follows. In the access-permitted area with a low alert level, an area with a low threatening effect, that is, a non-permission signal notification from the speaker 41 and lighting of a light (indicator lamp) 46 are selected. Thereby, it is possible to alert an intruder into the area. In a warning area with an intermediate warning level, an intermediate threatening effect is selected, that is, warning signal notification from the speaker 41 and blinking of a light (indicator light) 46 are selected. This makes it possible to intimidate an intruder into the area. In a warning area with a high warning level, a high threatening effect, that is, warning signal notification from the speaker 41 and lighting of a light (red rotating lamp) are selected. As a result, it is possible to increase the degree of intimidation of an intruder into the area and prompt the user to leave the area.

  In the building security system 90 having the above-described configuration, the home server 31 (which also corresponds to a setting unit and a warning control unit) performs an alarm process in addition to the authentication process and the operation control of the shutter device 61 described in the first embodiment. The following operations are performed.

  When entry to the site 11 is detected and the person is recognized as a suspicious person in the authentication process, it is determined which area of the areas A to D the suspicious person has entered, and the intrusion area is Determine which stage area is applicable. Then, the alarm device 35 installed in the intruded area is selected, the operation of the alarm device 35 is controlled, and the alarm contents in the stage area (warning level) associated with the intrusion area are executed. That is, when approaching the approach area A which is an access permission area, the alarm device 35 in the area A is controlled to notify the non-permission signal and turn on the light (indicator lamp) 46. When the vehicle enters the parking area B or the garden area C, which is a warning area, the warning device 35 in the same area B or C is controlled to flash a warning signal and a light (indicator light) 46. When entering the wall-side area D, which is a warning area, the alarm device 35 in the area D is controlled to perform warning signal notification and lighting of a light (red rotating lamp). Each operation described above is performed based on a data table (see FIG. 14) of the alarm database stored in the storage unit 52 of the home server 31.

  According to the building security system 90 of the second embodiment, the following advantageous effects can be obtained in addition to the first embodiment.

  When a suspicious person is detected in any of the areas A to D of the site 11, the alarm contents of the stage area set in the area are implemented by the alarm device 35 installed in the area. In this case, since the stage area is staged according to the alert level, a warning according to the alert level of the intrusion area is notified in the area. The security performance of the house 13 can be strengthened by vigilance of the site 11 itself. In addition, since an unbalanced warning is not notified to the intrusion area, the system can be always operated to constantly monitor a suspicious person. Therefore, the strengthening of the crime prevention performance using the security of the site 11 itself is sure.

[Other Embodiments]
It should be noted that the present invention is not limited to the two embodiments described above, and can be implemented, for example, in the form shown as another example below.

  In the said embodiment, although user ID used as authentication object is acquired from the portable device 36, it may replace with it or may use it together and may use another authentication system. For example, when a face authentication system is used together, resident's face information (information such as contour, eyes / nose / mouth arrangement) is also registered as a user ID. And an authentication process is implemented with the person's face information image | photographed with the surveillance camera etc. which were installed in each area | region AD. If face information of a person other than the resident is transmitted to the home server 31, it is possible to leave it to the resident to determine whether or not the authentication is OK. Further, the face information once determined as authentication OK may be stored in the database of the storage unit 52 at the judgment of the resident, and after that, it may be automatically determined as authentication OK.

  In the above embodiment, the building security systems 30 and 90 applied to the house 13 have been described. However, the building may be an apartment house instead of the illustrated detached house 13 or may be a building other than the house 13. May be. Buildings other than the house 13 include buildings built adjacent to the house 13 such as a garage, a storeroom, and a warehouse. FIG. 15 shows a plan view when an independent garage is built as a specific example. As shown in FIG. 15, it is preferable that the wall-side region D is set not only for the house 13 but also for the independent garage 101.

  In the above embodiment, the window portion 17 of the house 13 corresponds to the opening, but the opening may be the entrance / exit of the attached garage or the entrance / exit 102 of the independent garage 101 (see FIG. 15). Good.

  In the said embodiment, although the part except the residential building space of the site | part 11 is divided into four area | regions AD, dividing into a some area | region is not essential and it is good also as one area | region as a whole. In addition, the region may be partitioned regardless of the various spaces on the site 11, or the region may be partitioned by installing a boundary object or the like. In short, the number, size, shape, etc. of the area are appropriate, taking into consideration the size and shape of the site 11, the relationship with the house 13, security-related problems such as the surrounding situation, and various circumstances such as budget. It is decided that the security is made.

  As shown in FIG. 15, when the shutter device 61 is also installed at the entrance / exit 102 of the independent garage 101 or the like and there are a plurality of shutter devices 61 on the site 11, the area is divided according to the installation location of the shutter device 61. You may do it. In the example shown in the figure, there are two shutter devices 61 in the front area E of the house 13 and the independent garage 101, and accordingly, the housing is divided into a house front area E1 and a garage front area E2. In this case, when a person is detected in any region, the home server 31 controls the shutter device 61 corresponding to the region. As a result, the shutter device 61 is controlled for the opening (window 17 or doorway 102) that is most likely to be invaded, and an efficient crime prevention measure can be implemented. However, even in this case, when a person is detected in the wall area D, it is preferable to control all the shutter devices 61. This is because the crime prevention property is not lowered.

  In the above-described embodiment, the example in which the stage area is set to three stages has been described. However, the stage area may be set to two stages or four stages. For example, in the case where two levels are set, it is conceivable as an example that the approach area A is an area with a low warning level and the other areas B to C are areas with a high warning level. In addition, in the case where four stages are set, as an example, the vicinity of the entrance 15 and the back door of the house 13 is divided as a house entrance / exit area separately from the wall area D, and the area is set as an area with the highest alert level. Conceivable. Even in the case where two steps or four steps are set in this way, in the first embodiment, the shutter device 61 is controlled and alarm processing is performed only when entering the region other than the approach region A, and the second embodiment. In the form, it is preferable that alarm content with a higher threat level is selected each time the level of the alert level increases.

  In the above embodiment, the human detection sensor 34 is used as an equivalent of the human detection means, but it may be a surveillance camera or the like. Moreover, although the human sensor was mentioned as an example of the human detection sensor 34, a light projection / reception sensor, a vibration sensor, etc. may be sufficient. If it is a light projection / reception sensor, it is preferable to install on the boundary line of each area | region. Moreover, if it is a vibration sensor, it is good to install in the boundary structure 12, or install in piping (for example, a water pipe etc.) embedded in the ground of the site 11. In the latter case, in order to improve the detection accuracy by the sensor, it is preferably installed in a pipe passing through a portion where sand or gravel is laid.

  In the above embodiment, the alarm device 35 is used for warning notification, but it is also conceivable to use a sprinkler or the like. Moreover, not only the warning notification by the warning device 35 but also a photographing device such as a surveillance camera may be installed as a content of the warning control to be executed to photograph the intruder. Such an imaging apparatus can also prompt an intruder who is afraid of being identified by shooting to leave the site 11. In addition, information that a suspicious person has entered may be transmitted to the outside (for example, a private security company or a police organization).

  In the above embodiment, the shutter device 61 is configured such that the upper three slats 65 are opened and closed by the opening / closing guide mechanism 71, but a function of opening and closing all the slats 65 may be added. Thereby, a further air permeability can be ensured and a ventilation function can be improved.

  In the above embodiment, the mode is automatically set by executing the mode transition process. However, the mode is selected by manually operating the operation unit 32 assigned to each mode. You may do it. Further, a configuration in which automatic setting and manual selection are used together may be used. Thereby, the mode which a resident desires can be selected arbitrarily and can be implemented. And the kind of mode is not limited to the 3 modes mentioned above, For example, you may divide into the mode with a high alert level and the mode with a low alert level also at the same time at home.

  In the above embodiment, the approach area A is associated with the access permission area, the parking area B and the garden area C are associated with the warning area, and the wall area D is associated with the warning area. The stage area associated with A to D may be arbitrarily changed. Further, the timer function of the timer unit 55 may be used to automatically change according to the time zone. For example, it may be possible to set all the areas A to D as warning areas during the night time zone. In the first embodiment, since alarm processing is performed in the warning area, if the setting of the stage area can be changed in this way, the alarm device can be set in the warning area other than the wall area D. 35 is installed.

  In the above embodiment, the top three slats 65 are opened in the home mode and in the absent mode during the daytime, and closed in the sleep mode and the absent mode during the nighttime. The state of the slat 65 is arbitrary depending on the state. For example, in the absence mode, the slat 65 may be closed regardless of the time zone.

  In the above embodiment, the main control unit 51 discriminates whether it is a daytime time zone or a nighttime time zone by the time counting function of the timer unit 55. As such a time zone discrimination means, for example, a solar radiation sensor is used. Etc. may be used. The solar radiation sensor is a sensor that detects the amount of external light irradiation, and can determine whether it is a daytime zone or a nighttime zone from the detected solar radiation intensity. In this case, the solar radiation sensor is preferably installed in a place that is not easily affected by shadows, such as on the ridgeline of the roof 14.
