It is characterized by.

  According to invention of Claim 1, the load control apparatus which received the signal which means that the window glass was destroyed by the radio signal which is a radio wave medium makes a lighting fixture light from a light extinction state, or has already lighted. It controls to change the lighting level of the lighting equipment. That is, since a radio signal of a radio wave medium that causes a diffraction phenomenon or a transmission phenomenon is used as compared with an optical signal having strong straightness such as LED light, an intruder has entered because the window glass has been broken, or simply play equipment. As the projectile from outside the building, such as a ball, breaks the glass, the load control device can reliably receive events that are almost abnormal as long as the glass scatters and is dangerous. , It becomes possible to inform the family member of the abnormal breaking news as the most easily understood visual act.

  According to the invention of claim 2, when a roof side sensor is further added to the load control system of claim 1, and the load control device receives at least one of signals from the roof side sensor and the window glass breaking sensor, In addition to controlling lighting fixtures as described in Item 1, it is possible to step-control loads including, for example, living environment equipment such as air-conditioning equipment. Before the warning is issued, it is possible to predict the abnormality and notify the householder of the abnormality step by step with load stage control. At this time, radio signals are transmitted and received between the load control device and the roof side sensor or between the load control device and the window glass breakage sensor by a time division multiplexing method or a frequency multiplexing method. Since the signal and the radio signal from the window breaking sensor do not collide, the load control device can reliably recognize the abnormal event.

  According to the invention of claim 3, the load control device that receives a signal that means that a window has been opened or that a human body has approached the building via a radio signal that is a radio wave medium, Control is performed so as to turn on the light from the extinguished state or to change the lighting level of the luminaire that is already lit. That is, since a radio signal of a radio wave medium that causes diffraction and transmission phenomena is used compared to an optical signal having strong straightness such as LED light, an intruder is suspected of having opened a window or approaching the human body. Can be reliably received by the load control device, and it is possible to notify the householder of the abnormal warning as the most easily understood visual act by lighting the lighting fixture or changing the lighting level. At this time, in order to transmit and receive radio signals between the load control device and the roof side sensor or between the load control device and the window opening / closing sensor by the time division multiplexing method or the frequency multiplexing method, the wireless signal from the roof side sensor is used. And the radio signal from the window opening / closing sensor do not collide with each other, so that the load control device can reliably recognize the abnormal event.

  According to invention of Claim 4, the load control apparatus which received the signal meaning that the window was opened or the window was cracked via the radio signal which is a radio wave medium makes a lighting fixture light from a light extinction state. Or control to change the lighting level of a luminaire that is already lit. In other words, since a radio signal of a radio wave medium that causes a diffraction phenomenon or a transmission phenomenon is used in comparison with an optical signal having strong straightness such as LED light, an event that is suspected of intruder occurrence that a window has been opened, and a window Load control of events that are almost abnormal as long as the glass is broken and an intruder has entered, or because a flying object such as a playground equipment ball breaks the glass and the glass is scattered In addition to being able to be reliably received by the device, it is possible to notify the householder of the abnormal warning as the most easily understood visual act by lighting the lighting fixture or changing the lighting level. At this time, since there may be a plurality of intruders, the window glass breaking sensor and the window opening / closing sensor are not necessarily provided in the same window, and may be distributed in different windows, It may be attached to a window. And since a radio signal is transmitted / received between the load control device and the window glass break sensor or between the load control device and the window opening / closing sensor by a time division multiplexing method or a frequency multiplexing method, a wireless signal from the window glass break sensor is used. Since the signal and the radio signal from the window opening / closing sensor do not collide, the load control device can reliably recognize the abnormal event.

  According to the fifth aspect of the present invention, not only the automatic control of the luminaire and load as in the first to fourth aspects, but also the luminaire can be forcibly turned on or forcibly changed by the operation input to the operation switch. If an abnormality occurs in the transmission function of each of the sensors of claims 1 to 5 or if the transmission power is insufficient due to battery exhaustion, a backup measure such as an operation input to the operation switch can coexist.

  And according to invention of Claim 6 thru | or 9 which combined the aspect of the above Claim 1 thru | or 5, after a 1st predetermined radio signal is transmitted to a load control apparatus from a shop side sensor, it continues from a window opening / closing sensor. When the second predetermined radio signal is transmitted to the load control device, there is a high possibility that a suspicious person is trying to enter the room through the window, and this can be distinguished from the case where the housekeeper opens and closes the window from the inside. Further, when the third predetermined radio signal is transmitted from the window side sensor to the load control device after the first predetermined radio signal is transmitted from the shop side sensor to the load control device, the suspicious person breaks the window glass and forcibly pulls it. It is very likely that you are trying to get inside. Therefore, it is possible to distinguish whether the person is a suspicious person.

  In addition, when the first predetermined wireless signal is transmitted from the shop side sensor to the load control device, it can be seen that a person has entered the detection area of the outdoor shop side sensor. You can let them know that a person has come by letting them play or chime. At this stage, since there is a high possibility that the person is not a suspicious person, the load may be turned on at the first stage having a relatively low level. After the first predetermined wireless signal is transmitted from the roof side sensor to the load control device, when the second predetermined wireless signal is transmitted from the window opening / closing sensor to the load control device, the suspicious person tries to enter the indoor through the window. This can be distinguished from the case where the housekeeper opens and closes the window from the inside. At that time, the load control device may turn on the load in the second stage having a higher level than the first stage. Furthermore, after the first predetermined radio signal is transmitted from the roof side sensor to the load control device or when the third predetermined radio signal is transmitted directly from the window glass breaking sensor to the load control device, the suspicious person breaks the window glass. Therefore, the load control device only has to turn on the load in the third stage at the highest level. As a result, it is possible to provide a load control system having a function of a crime prevention device capable of reporting intruder intruders to indoor dwellers step by step. In addition, as a load, an illuminating device, an alarm device, a reporting device for a security company, an electric lock (automatic door lock), or the like can be used. When the load is an electric lock, the second stage and the third stage can be unlocked. As a result, the family members can evacuate to the outside quickly.

  According to the invention of claim 10, by setting a lighting time in the operation switch in advance before the user goes out, it is possible to turn on the lighting device before returning home, and to make it appear to be at home. . As a result, a crime prevention effect can be obtained to prevent a suspicious person from entering. In addition, when the absence is made for a long period of time, the lighting device can be turned on and off at a predetermined time every day.

  According to the invention of claim 11, when a plurality of lighting devices are connected to the load control device that is the operation target of the operation switch, it is as if there is a person by changing the brightness of the plurality of lighting devices and lighting them. It is possible to produce as if there is, and even when it is absent, it is possible to make it appear to be at home. As a result, a crime prevention effect can be obtained to prevent a suspicious person from entering.

  According to the invention of claim 12, even when it is absent for a long period of time, the lighting time, the light-off time, and the lighting device to be lighted can be controlled randomly or according to a predetermined pattern, and are the same at the same time every day. The unnaturalness that the lighting device is turned on and off can be eliminated. Furthermore, it is also possible to control the brightness of the lighting device at the time of lighting randomly or according to a predetermined pattern. Thereby, it can be made difficult to understand that the person is absent for a long time, and the crime prevention effect can be further improved.

  According to the invention of claim 13, the user can control lighting, extinguishing or dimming of the lighting device by using a mobile phone or the like from the outside, and the lighting device is turned on even when absent, so that the user is at home. It is possible to pretend to be.

  Furthermore, the load control devices 31... May be configured to receive a wireless signal from a wireless Internet adapter (wireless terminal device) 82 connected to the Internet. In that case, the user can control lighting, extinguishing or dimming of the lighting devices 21...

  The shop side sensor 41 provided under the eaves of the entrance 11 has functions of an illuminance sensor and a human body sensor, and when the outdoor illuminance becomes a certain illuminance or less, or the outdoor illuminance becomes a certain illuminance, In addition, when a person enters the predetermined detection area, the presence of the person is detected, and a predetermined lighting signal for notifying the user that the luminance is below a predetermined illuminance is detected using radio waves as a medium. 1 A predetermined radio signal is transmitted wirelessly to the nearest load control device 31. When the load control device 31 receives the lighting signal or the first predetermined radio signal from the store side sensor 41, the load control device 31 turns on (lights) the lighting device 21. It should be noted that when the outdoor sensor 41 exceeds a certain illuminance or when the first predetermined radio signal is transmitted and the presence of a person is no longer detected within a predetermined detection area, A predetermined light extinction signal informing that the person has left is wirelessly transmitted to the load control device 31. When the load control device 31 receives the light extinction signal from the store side sensor 41, the lighting device 21 is turned off (extinguishes). Other shop side sensors 42 to 44 have a function of a human body detection sensor, and detect a person using a radio wave as a medium when a person enters a predetermined detection area. A first predetermined radio signal for informing the user is transmitted wirelessly to the nearest load control devices 35-37.

  Human body sensors 71, 72, and 73 provided at the entrance 11, the corridor 12, and the stairs 13 detect the presence of a person when a person enters a predetermined detection area, and detect the person using radio waves as a medium. The fourth predetermined radio signal that informs the detection is wirelessly transmitted to the nearest load control device 31, 32, or 33, and after the fourth predetermined radio signal is transmitted, the presence of a person within a predetermined detection area for a certain period of time. When it is no longer detected, a fifth predetermined radio signal notifying that the person has left is transmitted wirelessly to the load control device 31, 32 or 33. The load control devices 31, 32, and 33 function to turn on or off the lighting devices 21, 22, 23, and 24 in accordance with the fourth predetermined wireless signal or the fifth predetermined wireless signal from the human body sensors 71, 72, and 73, respectively. And a normal switch function for turning on or off the lighting devices 21, 22, 23, and 24 by user operation.

  The load control devices 34 to 37 and the like provided in the living room 14 and the bedroom 16 or 17 turn on the lighting devices 25 to 28 or the like according to a predetermined control signal transmitted from the operation switch (remote control device) 81 or the like. It has a function of controlling illuminance at the time of off and on.

  The window opening / closing sensors 51 and 52 detect the open or closed state of the window 2 or 3, and use the radio wave as a medium to send a second predetermined radio signal corresponding to the opening operation of the window to the nearest load control devices 36 and 37. Wirelessly transmit. Similarly, the window glass break sensors 61 and 62 detect that the window glass has been broken, and use the radio wave as a medium to send a third predetermined radio signal informing that the window glass has been broken to the nearest load control device 36 and 37 is transmitted wirelessly.

  Each of the load control devices 31 to 37 performs peer communication with each other via wired communication, or uses one load control device (for example, the load control device 34 or 35 provided in the living room 14 or the kitchen 15) as a master, Performs master-slave communication with other load control devices as slaves. Further, the individual load control devices 31 to 37 are operated by a time division multiplexing method or a frequency multiplexing method, with the operation switch 81..., The roof side sensor 41..., The window opening / closing sensor 51. Receives signals from.

  Regarding the load control device (wall switch), the shop side sensor, the human body sensor, the window opening / closing sensor, the window glass breaking sensor, etc. Will not be described.

  Next, the security function in the load control system will be described with reference to the flowchart shown in FIG. When all the lighting devices 21 to 28 are turned off or one or more lighting devices (for example, the lighting devices 21, 24, 27, etc.) are turned on in a predetermined sleeping mode (so-called bean bulb on), a certain time has elapsed, Alternatively, when the human body detection sensors 71 to 73 do not detect the presence of a person for a certain time after transmitting the fifth predetermined wireless signal (light-off signal), it can be determined that the householder is sleeping (# 1). Therefore, the load control devices 31 to 37 determine whether or not the first predetermined radio signal is transmitted from any of the roof side sensors 41 to 44 (# 2). When any one of the load control devices 31 to 37 receives the first predetermined radio signal from the shop side sensors 41 to 44, any or all of the lighting devices 21 to 28 are turned on (lighted) and the lighting state of the lighting device is turned on. Is set to the first stage having a slightly higher luminance than the sleep mode, or the lighting state of the lighting device already turned on is set to the first stage (# 3). As a result, it is possible to inform a sleeping home person that there is a person outdoors and that the person is likely to enter the house. At this stage, a person who is outdoors is not necessarily a suspicious person, and may be a housekeeper who comes home late. There is also the possibility that small animals such as birds and cats have invaded. Therefore, the brightness of the illuminating devices 21 to 28 is set to such a level as to call attention to a sleeping householder.

  Next, when any or all of the lighting devices 21 to 28 are turned on in the first stage, further receiving a second predetermined radio signal from any one of the window opening / closing sensors 51 or 52 (YES in # 5). Since the suspicious person is likely to open the window and enter the room, the load control devices 31 to 37 change the lighting states of the lighting devices 21 to 28 to the second stage where the luminance is higher than the first stage ( For example, all lighting is performed, that is, lighting with the highest luminance) (# 6). Alternatively, when any or all of the lighting devices 21 to 28 are turned on in the first stage and further receive a third predetermined radio signal from the window glass break sensor 61 or 62 (YES in # 7), the suspicious person Is very likely to break into the window and forcibly enter the room, so that the load is in a third stage (eg certain lighting) that is equal to or higher than the second stage (eg full lighting). The device is blinked with the highest luminance, and the lighting device that hits the evacuation route is turned on with the highest luminance) (# 8).

  In addition, when the housekeeper who came home late at night enters the room indoors by unlocking the entrance door (when it is not a suspicious person), for example, the shop side sensor 41 does not detect the presence of a person. When the first predetermined radio signal disappears (YES in # 4), the lighting devices 21 to 28 that have been turned on in the first stage are turned off or returned to lighting in the original sleeping mode (# 9).

  Furthermore, when a load control device negative 31 to 37 is connected with a warning device 91, a reporting device 92 to a security company or an electric lock (auto door lock) 93 as a load, various measures can be taken depending on each stage. It is. For example, when the first predetermined wireless signal is transmitted from the shop side sensors 41 to 44, the alarm device 91 may be configured to sound a chime to notify the householder that a person has come. As described above, since it is not necessarily a suspicious person at this stage, it is not necessary to operate the reporting device 92 or the electric lock 93 to the security company. Next, when the second predetermined wireless signal is transmitted from the window opening / closing sensor 51 or 52, the possibility of being a suspicious person is considerably increased. Therefore, the alarm device 91 is increased in volume to generate an alarm. The notification device 92 or the electric lock 93 may be operated. Further, when the third predetermined radio signal is transmitted from the window glass breaking sensor 61 or 62, since the suspicious person is about to enter the room, the alarm device 91 is set to the maximum volume to generate an alarm. Then, the reporting device 92 or the electric lock 93 to the security company is operated. As a result, the family members can evacuate to the outside quickly.

  When the second predetermined wireless signal is transmitted directly from the window opening / closing sensor 51 or 52 without transmitting the first predetermined wireless signal from the shop side sensors 41 to 44, the window 2 or 3 is usually indoors by a householder. Can be distinguished from the case where a suspicious person tries to invade. On the other hand, there may be a case where a suspicious person can approach the window 2 or 3 directly while avoiding the detection areas of the shop side sensors 41 to 44. Therefore, in the former case, since there is a possibility of false alarm, only the lighting device 27 or 28 in the room provided with the window opening / closing sensor 51 or 52 that has transmitted the second predetermined wireless signal or only a specific lighting device is turned on. You may comprise.

  In addition, when the third predetermined wireless signal is transmitted directly from the window glass breaking sensor 61 or 62 without the first predetermined wireless signal being transmitted from the shop side sensors 41 to 44, the window glass is broken indoors by a householder. It is conceivable that the suspicious person directly approached the window 2 or 3 and broke the window glass by avoiding the detection area of the shop side sensors 41 to 44. In any case, because it is an abnormal situation and there is a risk of injury due to broken pieces of broken glass, etc., it is configured to turn on a specific or all lighting devices 21 to 28 and generate a predetermined alarm. Also good.

  Furthermore, when the first predetermined radio signal is transmitted simultaneously or after a plurality of shop side sensors 41 to 44, there is a high possibility that a suspicious person is trying to enter the room. Without waiting for the transmission of the second predetermined radio signal or the third predetermined radio signal from the window breaker sensor 61 or 62, the specific or all lighting devices 21 to 28 are turned on and an alarm sound is generated from the alarm device 91. You may comprise. Further, the human body sensing function of the human body sensor or the shop side sensor may be of a type that senses heat rays emitted from the human body using a pyroelectric element, or the presence or absence of the human body is estimated by image processing. It does not matter if it is of the type to be used.

  As described above, according to the present invention, it is detected that a person is approaching by a house side sensor provided on the outer wall of the house or under the eaves, for example, the lighting device is dimly lit, and the person comes to the housekeeper. By detecting that the window has been opened by the window open / close sensor or that the window glass has been broken by the window glass break sensor, the lighting device is turned on at the highest brightness, for example, and a warning is given to the householder. In addition, an alarm sound can be generated and a security company can be notified and the electric lock can be unlocked to secure an escape route. Although not particularly described in the description of the above embodiment, power supply to the load including each lighting device is performed by wiring (not shown), and the load control device (wall switch) is turned on or off and turned on. Needless to say, it controls the stage of the load.

  Furthermore, the present invention can be applied in various ways. As described above, when the operation switch has a timer function, the lighting device is turned on before returning home by setting the lighting time in the operation switch in advance before the user goes out. It is possible to make it look like this. As a result, a crime prevention effect can be obtained to prevent a suspicious person from entering. In addition, when the absence is made for a long period of time, the lighting device can be turned on and off at a predetermined time every day. Furthermore, since it is unnatural that the same lighting device is turned on and off at the same time every day, the lighting time, the turn-off time, and the lighting device to be turned on can be controlled randomly or according to a predetermined pattern. Furthermore, when the operation switch has a lighting scene effect function, it is possible to control the brightness of the lighting device at the time of lighting randomly or according to a predetermined pattern. Furthermore, when a wireless Internet adapter (wireless terminal device) is connected to the Internet, the user can control lighting, extinction or dimming of the lighting device using a mobile phone or the like from the outside, It is possible to turn on the lighting device even when you are away, and make it appear to be at home.

  In the above-described embodiment, it has been described that the wireless transmission method between each wireless sensor terminal and the load control device may be a time division multiplexing method or a frequency multiplexing method. As for the time division multiplexing method, a basic style is that one load control device receives each wireless report of a plurality of wireless sensor terminals by time division, and is called, for example, TDMA, specific low power wireless, or low power wireless. A general-purpose method can be applied. Of course, the number of load control devices is not limited to one, and each of a plurality of wireless sensor terminals may wirelessly report to a plurality of load control devices. Regarding the frequency multiplexing method, the basic style is that one load control device receives each wireless report of a plurality of wireless sensor terminals by frequency division. Of course, the number of load control devices is not limited to one, and each of the plurality of wireless sensor terminals may wirelessly report to a plurality of load control devices as long as there is room in the band of the used frequency band.
