Abstract

PURPOSE:To prevent an operation defectiveness in a home automation system caused by a misoperation of locking of a door of the entrance or an in/out setting switching means, etc., and to improve its reliability by detecting the human body which follows up opening/closing of the door of the entrance and deciding being-at-home or going-out. CONSTITUTION:The title system is provided with an opening/closing detecting means 15 for detecting opening/closing of a door of the entrance, a human body detecting means 14 provided in the vicinity of the entrance, and a detecting means for detecting man's going-out and returning-home from a sequence of opening/closing and a human body detection. In this state, when the result of operation of an arithmetic means 16 for subtracting '1' from the number of persons set in advance, when its detecting means detects going-out, and adding '1' to the result of its subtraction, when returning-home is detected becomes zero, it is discriminated to be absent. In such a manner, the deterioration of a function of the automation system caused by forgetting to lock a key, mischief by an infant child, forgetting of setting being-at-home/going-out, an error of setting, etc., can be prevented.

Description

[Detailed Description of the Invention] (a) Industrial Application Field This invention is mainly used to improve the reliability of home automation systems, and to improve the reliability of home automation systems when family members are at home or away from home.
Concerning a system for determining.

<a> Conventional technology Conventionally, this type of home automation discrimination system distinguishes between "at home" and "going out (absent)" based on the locked state of the front door and the setting state of the setting means, and a telecontrol system (see, for example, Japanese Utility Model Application Publication No. 129864/1986).

(c) Problems to be solved by the invention However, in home automation systems that detect when someone is home or out based on the locked state of the front door, some people forget to lock the door when they go out, or lock the door even though they are home. If it is put away (especially due to a prank by a small child), a state different from the original state will be detected. Additionally, in a home automation system that detects whether you are home or out using a home/out setting switching means, if you forget to switch, the setting may be set to go out even when you are at home.
While you are out of town, your home settings may be set to be home regardless of who you are. For this reason, the telecontrol system using a telephone line could not be used while you were out, and the security system could not function adequately, leading to an unexpected accident, or conversely, the telecontrol system could be activated while you were at home. There was a problem that this caused anxiety to the family members.

The present invention has been made in consideration of such circumstances, and therefore provides a discrimination system that improves the functionality and reliability of a home automation system by clarifying whether a person is at home or away from home.

(d) Means for Solving the Problems This invention provides an opening/closing detection means for detecting and outputting the opening/closing of an entrance door, a human body detection means installed near the entrance for detecting and outputting a human body, and and a detection means for detecting when a person goes out and returns home from the output order of the human body detection means, and when the detection means detects going out, subtracts 1 from the preset number of people, and when the detection means detects coming home, the subtraction result A calculation means that adds l to the calculation means, and when the calculation result of the calculation means becomes zero, it is determined that the person is absent, and when it is 1 or more, it is determined that he is home.53Q
This is a discrimination system for home automation that has a sex characteristic as a discrimination means.

Microswitches, photoelectric switches, magnetic sensors, etc. are used as detection means for detecting the opening and closing of the entrance door, and pyroelectric infrared sensors (ferroelectric materials with sensitive spontaneous polarization) are used as detection means for detecting human bodies. Because of its temperature dependence, Senna utilizes the so-called pyroelectric effect, a phenomenon in which surface charges move in and out when a slight temperature change is applied to the material.
Sensors such as thermopiles (thermocouples that absorb infrared rays radiated from a heat source and generate thermoelectromotive force, or multiple pairs integrated in series) are used.

(E) Function The number of people at home is counted from the number of people entering and exiting through the entrance, and it is determined from that number whether family members are home or absent (going out). Therefore, it is possible to prevent the home automation system from deteriorating in functionality due to forgetting to lock the door, mischief by small children, forgetting to set the home/outside settings, or erroneously setting the home automation system.

(f) Examples The present invention will now be described in detail based on examples shown in the drawings. Note that this invention is not limited to this.

A householder initializes the home bus controller l using the initial setting switch 13 in order to make the home automation system function. The initial setting is to register the number of household members necessary to determine whether the user is going out or at home. When the number of family members is registered and set in the home bus controller l by the initial setting switch 13, the home bus controller!
sends the home mode setting information to the security unit 4 via the home bus 2 and the ink-face unit 3.
1, the security unit 4 transmits information from the security sensors 5 (intrusion detection sensor, smoke detection sensor, fire detection sensor, etc.) to the home bus controller 1 via the interface unit 3 and the home bus 2, Security unit 4 is set to home mode. Furthermore, the Baumbus controller l transmits the home mode setting information to the telecontrol unit 7 via the interface unit 6, the telecontrol unit 7 switches the telephone 8 to the telephone line 9 side, and transmits the telecontrol release information to the interface unit 6. is transmitted to the home bus controller 1 via the home bus 2, and the telecontrol unit 7 is set to at-home mode (telecontrol cannot be used). Further, the home bus controller 1 transmits information on the number of household members via the home bus 2 and the interface unit 11 to the control unit 16 of the out/at-home detection device 12 for initial setting.

The control devices 1O are air conditioners, cookers, lighting fixtures, equipment A, etc., and are controlled in the home by the home bus controller 1, or from outside the home via the telephone line 9 and connected to the home bus via the telecontrol unit 7. It is controlled by a controller l.

Figures 3(a) and 3(b) show a case in which a human body detection sensor is installed inside the front door, and a case in which a human body enters the house from outside, and a case in which a human body exits from inside the house to the outdoors, respectively. It is a layout explanatory diagram. The operation of this system in this arrangement will be explained using the flowchart shown in FIG. When the system is set to the home mode as described above, as shown in FIG. 3(a), the human body N1 is

If the human body detection sensor 14 does not detect the human body M in the sensing area S (as indicated by arrow A in FIG. 4), this state is maintained until the next door closes. Here, when it is detected that the door has been closed, and then when the human body M is detected, it is known that the door has been opened from outside and the person has returned home, and the control device I6 sets the number of household members counter by one. Add the numbers to find out the number of people in your household. If the number of people is 2 or more, the at-home mode is continued, and if the number of people is 1, the at-home mode setting information is transmitted to each unit controller via the home bus 2 as described above, and the at-home mode is set. At this time, if no human body M is detected, it is determined that the person opened the door twice but closed the door without entering the house, and the control device 16 keeps the counter for the number of people in the household and checks the number of people. Here, if the number of household members is 1 or more, the at-home mode is continued; if the number is zero, the out-of-home/at-home detection device 12 sends out-of-home mode setting information via the interface unit 11 to the home bus 2. Transfer to bus controller I. The home bus controller 1 transmits out-of-home mode setting information via the home bus 2 and the interface unit 3 to the security unit 4, and the out-of-home mode is set. Further, the home bus controller 1 transmits setting information for the out-of-home mode to the telecontrol unit 7 via the home bus 2 and the interface unit 6, and the telecontrol unit 7 switches the telephone 8 to the telecontrol unit side, and the telecontrol unit 7 switches the telephone 8 to the telecontrol unit side. Setting information is sent via the interface unit 6 and further to the home bus 2.
to the home bus controller I, and the telecontrol unit 7 is set to the out-of-home mode (telecontrol can be used).

When the door opening/closing detection sensor 15 detects that the door has opened, and then the human body detection sensor 14 detects the human body M (as shown by arrow B in Figure 4), the state remains until the next time the door closes. Please continue. Here, when it is detected that the door has been closed, and when the human body M is detected again, it is determined that the door was opened - degree, but the door was closed without being allowed to go outdoors, and the control device 16
will continue to stay at home mode with the household member counter unchanged. At this time, if the human body M is not detected, Fig. 3(b)
When it is determined that the person has opened the door and gone out of the house, the control device 16 subtracts one from the number of household members counter to find out the number of household members. If the number of family members is 1 or more, the at-home mode continues, and if it is zero, the out-of-home mode setting information is transmitted to each unit controller via the home bus 2 and set to the out-of-home mode. be done.

Figures 5(a) and 5(b) show the cases in which a human body detection sensor is installed outside the front door, and the cases in which a human body enters the house from outside and the body exits from inside the house, respectively. The operation of the system in the arrangement relationship shown in FIG. 6 will be explained using the flowchart shown in FIG.

The process is as described above until the door is opened.

When the door open/close detection sensor 15 detects that the door has been opened, the human body detection sensor I4 detects a human body in the sensing area S.
1 is not detected (the flow of arrow B in FIG. 6), this state continues until the next door closes. Here, when it is detected that the door is closed and then the human body M is detected, the fifth
As shown in Figure (b), when it is determined that a family member has opened the door and left the house, the control device 16 subtracts one from the household member counter to find out the number of family members. Here, if the number of family members is one or more, the at-home mode is continued, and if there are zero, the out-of-home mode is set. At this time, if the human body M is not detected, it is determined that the door was opened, but the door was closed without going outside, and the control device 16 continues the at-home mode with the household member count counter unchanged.

When the door opening/closing detection sensor 15 detects the presence of the door Dh1, and then the human body detection sensor 14 detects the human body M (as indicated by arrow A in FIG. 6), this state continues until the next door closes. Here, if it is detected that the door is closed and the human body M is not detected again, it is determined that the person has returned home after opening the door from outside, as shown in FIG. 5(a), and the control device 16 adds one to the number of household members counter to find out the number of household members. If the number of people is 2 or more, the home mode will continue,
If the number of people is 1, the home mode is set. At this time again,
When the human body M is detected, it is determined that the householder who opened the door closed the door without entering the house, and the control device 1
Step 6: Check the number of people in your household by leaving the number counter as it is. Here, if the number of family members is 1 or more, the stay-at-home mode is continued, and if the number is zero, the out-of-home mode is set.

(G) Effects of the Invention According to this invention, by detecting the human body as the front door opens and closes and determining whether the person is at home or out, it is possible to prevent erroneous operations such as locking the front door or switching between home and out settings. Malfunctions of the main stem are prevented and its reliability is improved.
