Description

  The present invention relates to a security device with improved usability and a program thereof.

  Conventionally, this type of security device is, for example, as shown in FIG. 8 (see, for example, Patent Document 1).

FIG. 8 shows a conventional security device described in Patent Document 1. In FIG. As shown in FIG. 8, an open / close sensor 81 that is installed on a door or window to detect opening / closing thereof, a processing unit 82 that processes information of the open / close sensor 81, and an alarm notification that issues an alarm based on the processing result of the processing unit 82 It comprises means 83 and alarm notification cancellation means 84 for canceling alarm notification as a processing result by the processing unit 82.
Japanese Patent Laid-Open No. 8-110995

  However, in the conventional configuration, a switch or the like between the time when the opening / closing sensor 81 detects that a door or window has been opened and the processing unit 82 performs a process of issuing an alarm by the alarm notification means 83 after a predetermined time has elapsed. It is necessary for the user to operate the alarm notification canceling means 84, which is very troublesome.

  In addition, when the alarm notification canceling unit 84 does not allow the user to operate and detects an identification unit such as a transmitter carried by the user, the user must always have the transmitter. If you forget to have it, you cannot cancel the alarm.

  Further, when the alarm notification canceling unit 84 determines whether or not to cancel the alarm notification using the user's physical characteristics, there is an advantage that security is improved, but imaging is performed to recognize a face image, for example. There is a problem in that it is necessary to perform troublesome operations similar to the switch operation such as standing in front of the means, and it is not necessarily easy to use.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a security device that does not require a user to be aware of a warning state or perform any operation while keeping a warning against a suspicious person. To do.

  In order to solve the above-mentioned conventional problems, the security device of the present invention and the program thereof are provided in the vicinity of an opening of a building such as an entrance door or a window, and a human body detection means for detecting the presence or absence of a human body on the outdoor side, An opening / closing detection means for detecting the open / closed state of the door or window of the opening, and an intrusion determination means for determining the intrusion of a suspicious person based on the output of the human body detection means and the opening / closing detection means.

  As a result, it is necessary for the user to be conscious or perform some operation by the intrusion detection means judging by the operation of the human body detection means and the opening / closing detection means whether the door or window is opened from the indoor side or the outdoor side. In addition, it is possible to know whether a suspicious person has entered or opened by a user such as a family member.

  The security device and its program according to the present invention maintain a vigilance state in a natural living behavior without bothering the user's hand or possessing a special thing, and can protect a user such as a householder. It is possible to achieve the effect of not impairing the usability without judging a suspicious person and generating false information.

  1st invention is provided in the opening part vicinity of buildings, such as an entrance door and a window, The human body detection means which detects the presence or absence of the human body of the outdoor side, and the opening / closing which detects the opening / closing state of the door or window of the said opening part By comprising detection means, and intrusion determination means for determining the intrusion of a suspicious person based on the output of the human body detection means and the opening / closing detection means, the presence or absence of a human body on the outdoor side of the door or window, the door or Using the order and timing of opening and closing the windows, the intrusion determination means depends on whether the door or window was opened from the outdoor side, from the indoor side, and the timing etc. Because it is judged whether it is an intrusion by a suspicious person or a user such as a householder, it is possible to do something other than normal living behavior without causing a problem such as issuing an alarm by entering and exiting a user such as a householder Always without It is possible to realize a warning to the suspicious person.

  In the second invention, in particular, the human body detecting means of the first invention is configured to detect infrared rays emitted from the human body and detect the movement of the human body according to the temporal change thereof, so that the user moves. Since there is an effect that the output of the human body detection means disappears when there is not, the movement can be easily detected.

  In the third aspect of the invention, in particular, the human body detection means of the first aspect of the invention is configured to detect a human body load with a piezoelectric sensor laid on the floor, and detect the movement of the human body based on temporal changes. Thus, as in the second invention, since the output of the human body detecting means is lost when the user is not moving, the movement can be easily detected, and the detection range is determined by the range laid on the floor. In addition, the intended warning range can be easily set even for openings of different sizes, and it can be difficult to understand that it is installed, so that the crime prevention effect is high.

  According to a fourth aspect of the present invention, in particular, the intrusion determination means according to any one of the first to third aspects of the invention is detected when the human body detecting means continues detecting the human body for a first set time or more after the human body detecting means detects the human body When it is detected that the door or window has been opened by the means, it is judged that the suspicious person has entered, and in the case of a user such as a householder, the laundry is taken out of the window by hanging the laundry. If you can assume that the door or door is not locked, such as if you are out of the door or picking up mail, or if you lock the door, hold the key. If you are a suspicious person trying to enter the room by breaking the lock on the outside of the door or window, it will take some time. , The time from human body detection to actual intrusion For this reason, the intrusion detection means determines that a person is suspicious if it takes more than the first set time after the detection of a human body on the outdoor side and is detected as a suspicious person. It has the effect of determining that it is a user, and can prevent false alarms when a householder temporarily goes outside and enters the room again.

  In particular, the intrusion determination means according to any one of the first to fourth inventions may be provided by the opening / closing detection means before the human body is detected by the human body detection means or without the human body being detected. When it is detected that a door or window has been opened, it is determined that it is not a suspicious person's intrusion, so that the window or door is opened from the indoor side and goes outside, or the window or door is simply opened. Since it is possible to catch an action, it is possible to prevent false reports caused by such an action by a user such as a householder.

  The sixth aspect of the invention is particularly the intrusion determination means of the fourth aspect of the invention from the time when the human body detecting means detects the human body and the human body detection is not detected after the human body detection continues for the first set time or longer. If the human body is detected again within the set time, the door or window is opened by the open / close detection means after the first set time has elapsed since the first time when the human body was detected and the human body detection is continuing. By detecting the suspicious person's intrusion when it is detected, the suspicious person who tries to intrude by doing work such as breaking the lock once leaves the detection area of the human body detection means for some reason, When returning to the front of the door, the intrusion determination means will continue to recognize that it is a suspicious person's action, and even if the time for detecting the human body again has not reached the first set time assuming the time required for intrusion, Or when the door is opened Since it is determined that is input has the effect of crime prevention can be higher.

  In the seventh invention, in particular, a hardware resource such as an electric / information device, a computer, or a server is provided by causing a computer to execute at least a part of the security device according to any one of the first to sixth inventions. By cooperating, it is possible to easily realize at least a part of the security device of the present invention. In addition, the program can be distributed / updated and installed easily by recording on a recording medium or distributing the program using a communication line.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a diagram showing the configuration of a security device according to the first embodiment of the present invention.

  In FIG. 1, an open / close detection means 101 is installed in a joinery, and an open / close sensor 102 that detects the opening / closing of a window or door when two magnets are separated or approached, and a first communication for transmitting the information. It comprises means 103. The human body detection means 104 is installed on the outdoor side of a window or door, and includes an infrared sensor 105 that detects infrared rays emitted by the human body, and a second communication means 106 for transmitting the information. Information from the open / close detection means 101 and the human body detection means 104 is transmitted to the information processing means 107 installed indoors via the third communication means 108, and the arithmetic processing unit 109 and a clock 110 for counting time are provided. An intrusion determination unit 111 that uses the intrusion determination unit 111 to determine whether a suspicious person has intruded, and an alarm notification unit 112 that notifies an alarm based on the processing result of the intrusion determination unit 111 are provided. The first communication unit 103, the second communication unit 106, and the third communication unit 108 will be described as a wireless communication unit, but may be a wired communication unit. Further, the open / close sensor 102 may be a system other than a magnet.

  FIG. 2 shows the installed state. Opening / closing detection means 101 and human body detection means 104 are installed on the sweep window 201 and the upper wall, respectively. The human body detection means 104 detects infrared rays of the human body 202 approaching the window from the outside. An information processing means 107 for processing information of the open / close detection means 101 and the human body detection means 104 is installed on the indoor wall. A state in which information is exchanged between the first communication unit 103, the second communication unit 106, and the third communication unit 108 is represented by an arrow 203.

  The operation and action of the security device configured as described above will be described below.

  First, the operation when an outdoor human body is detected will be described with reference to FIG. FIG. 3A shows an operation when a suspicious person is determined, and the time is shown on the horizontal axis.

When the human body detecting means 104 detects the presence of a human body on the outdoor side of the sweep window 201 by the output of the infrared sensor 105, the information is processed by wireless transmission via the second communication means 103 and the third communication means 108. The arithmetic processing unit 109 measures the residence time of the human body using the time measured by the clock 110.
At the stage where the residence time has passed the first set time T1, the intrusion determination means 111 determines that the suspicious person has entered when the open / close detection means 101 detects that the sweep window 201 has been opened thereafter. Enter the area (indicated by diagonal lines) and wait for information from the open / close detection means 101. When the two magnets of the open / close sensor 202 are actually separated and the open / close detection unit 101 detects that the sweep window 201 is opened, the first and second communication units 103 and 108 are used to Information is transmitted to the intrusion determination means 111, and at that time, the intrusion determination means 111 determines that a suspicious person has entered, and activates the alarm notification means 112. The alarm notification unit 112 issues an alarm indoors or calls a predetermined telephone number to notify a housekeeper or a security company on the road that a suspicious person has entered.

  Next, the operation shown in FIG. 3B is when a user such as a householder is detected. A human body is detected by the same operation as described above. However, if the opening / closing detection means 101 detects that the sweep window 201 is opened before measuring the first set time T1, it is determined that a suspicious person has entered. Therefore, the alarm notification unit 112 is not activated. In other words, the relationship between the staying time on the outdoor side of the window and the first set time T1 is shorter than the work time for a suspicious person to break into a lock in an attempt to enter the room, and a housekeeper temporarily goes outside. By setting it longer than the time it takes to enter the room again without being locked, it is possible to distinguish between the intrusion of a suspicious person and the entry of a householder.

  FIG. 4 shows the operation when going out from the indoor to the outdoor. In this case, the open / close detection means 101 detects that the sweep window 201 has been opened first. At this time, the human body detecting means 104 on the outdoor side does not detect the human body, and it can be seen that the window is opened from the indoor. In this case, the intrusion detection unit 111 does not activate the alarm notification unit 112 because it is determined that the action is by a family member. If the housekeeper actually goes outside after the window is opened, the human body detecting means 104 detects the human body as shown in FIG.

  Further, FIG. 5 shows an operation that is considered in order to further improve the security. When a suspicious person temporarily goes out of the detection range of the infrared sensor 105 for some reason and tries to enter from the sweep window 201 again. It is. When the human body detecting means 104 no longer detects the human body without opening the sweep window 201 from the state of entering the suspicious person judgment area described with reference to FIG. 3, the suspicious person who intends to enter temporarily removes the sweep window. Assuming that the user is away from 201, the time until the second set time T2 expires does not cancel the suspicious person judgment area. FIG. 5A shows a case where the detection range of the infrared sensor 105 is entered again in that state, and the sweep window 201 is opened within T2 time. FIG. This is a case where the sweep window 201 is opened while the human body is continuously detected. In either case, the intrusion determination unit 111 detects the alarm notification unit 112 when the open / close detection unit 101 detects that the sweep window 201 is opened. Start up.

  As described above, in the present embodiment, the human body detection unit 104 that detects the presence or absence of a human body on the outdoor side of the sweep window 201, the open / close detection unit 101 that detects the open / closed state of the sweep window 201, and the human body detection unit 104. And the intrusion determination means 111 that determines the intrusion of a suspicious person based on the output of the open / close detection means 101, and uses the presence / absence of a human body on the outdoor side and the order and timing at which the sweep window 201 is opened / closed. Depending on whether the intrusion determining means 111 is opened from the outdoor side or the indoor side, and the timing of the intrusion determination means 111, whether it is an intrusion of a suspicious person, a family member, etc. Because it is judged whether the user is going in or out, there is no trouble such as issuing an alarm when the user goes in and out of the house and other people, and other than normal living behavior. It is possible to always realize the alert to suspicious persons without cause the.

  In the present embodiment, the open / close detection unit 101 and the human body detection unit 104 are provided separately, but may be configured integrally, in which case the first communication unit 103 and the second communication unit are provided. There is an effect that 106 can be shared by one and installation work is simplified.

(Embodiment 2)
FIG. 6 is a diagram showing the configuration of the security device according to the second embodiment of the present invention.

  6 differs from Embodiment 1 in that a piezoelectric sensor 601 laid on the floor is provided in place of the infrared sensor 105 of the human body detecting means 104. Although FIG. 7 shows the state of the installation, it is laid in a range to be detected on the outdoor side of the sweep window 201. The piezoelectric sensor 601 detects a human body by detecting a change in load caused by an object placed thereon. Other operations and actions are the same as those in the first embodiment. As an effect of the present embodiment other than the first embodiment, since the detection range is determined by the range laid on the floor, it is possible to easily set the intended warning range even for openings of various sizes, Because it is difficult to understand that it is installed, the crime prevention effect increases.

  In the present embodiment, the human body detection means has been described using an infrared sensor or a piezoelectric sensor, but other sensors may be used.

  Note that the means described in this embodiment causes hardware resources such as a CPU (or microcomputer), a RAM, a ROM, a storage / recording device, an electrical / information device including an I / O, a computer, a server, and the like to cooperate. You may implement with the form of a program. In the form of a program, new functions can be easily distributed / updated and installed by recording them on a recording medium such as magnetic media or optical media or distributing them via a communication line such as the Internet.

  As described above, the security device and the program thereof according to the present invention can realize a warning state without affecting the user's daily activities, without being aware of the warning setting state, and effectively prevent false alarms. Therefore, the present invention can be applied not only to indoor and outdoor residences but also to security applications inside and outside doors of indoor rooms such as buildings.
