DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a security system, a security device and a security method embodying the present invention will be described below with reference to FIGS.
FIG. 1 is a configuration diagram showing a schematic configuration of the security system 1. The security system 1 is a system in which when a third party such as a theft or the like illegally enters the house 2 while going out, it notifies the resident who has returned to that effect and prevents the resident from entering the house 2 carelessly. . The security system 1 includes a controller 5 that controls locking / unlocking of the entrance door 4 based on wireless communication with the electronic key 3 owned by the resident, and an electrical drive based on commands from the controller 5 to lock the entrance door 4. It has an electric lock 6 that is in a state or an unlocked state, and an abnormality monitoring device 7 that controls the main control of the system. Note that the controller 5 corresponds to the collating means.

  The controller 5 is embedded in the entrance door 4 and includes an antenna 5 a that transmits and receives signals to and from the electronic key 3. When the controller 5 intermittently outputs the request signal Sre from the antenna 5a and receives the ID signal Sid transmitted from the electronic key 3 in response to the signal Sre, the controller 5 receives the ID code and its own ID code. It is possible to perform ID collation to be compared and lock and unlock the electric lock 6 on condition that ID collation is established. In addition, when the electric lock 6 receives a locking command from the controller 5, the dead bolt (not shown) is popped out by the drive motor to be locked, and when the unlocking command is received from the controller 5, the dead bolt is pulled in by the drive motor. It will be unlocked.

  The abnormality monitoring device 7 is attached to an indoor wall or the like, and can communicate with the controller 5 via wiring. The abnormality monitoring device 7 has a push button type warning mode setting switch 7a. After the switch 7a is pressed, the resident who owns the electronic key 3 goes out of the communication area of the antenna 5a and the electric lock 6 is turned on. When in the locked state, the operation mode of the security system 1 is set from the release mode to the alert mode. The abnormality monitoring device 7 is in an operating state when the security system 1 is in the alert mode, and is in a state of sequentially monitoring the presence or absence of unauthorized intrusion into the house 2. On the other hand, when the security system 1 is in the release mode, the abnormality monitoring device 7 is deactivated and the operation is stopped. The abnormality monitoring device 7 constitutes a determination unit and a control unit, and the warning mode setting switch 7a corresponds to the setting unit.

  In addition, the security system 1 includes a detection sensor 8 that detects that a third party has intruded into the house 2, a camera 9 that can photograph the site of the unauthorized intrusion, and a monitor that can broadcast video captured by the camera 9. 10. The detection sensor 8 can wirelessly communicate with the abnormality monitoring device 7, and the camera 9 and the monitor 10 are connected to the abnormality monitoring device 7 through wiring. The detection sensor 8 corresponds to detection means, the camera 9 corresponds to imaging means, and the monitor 10 corresponds to notification means (display means).

  The detection sensor 8 includes, for example, a door opening / closing sensor 8a for detecting unauthorized opening / closing of the window glass 11, an infrared sensor 8b for detecting that a person has entered the room, and the door opening / closing sensor 8a is connected to the window glass 11 with an infrared sensor. 8b is installed in each room. In addition to the sensors 8a and 8b, the detection sensor 8 includes, for example, a glass sensor that detects breakage of the window glass 11, an infrared beam sensor that detects entry of a person into the room, a heat sensor that detects heat, and the like. When the detection sensor 8 enters a sensing state (sensors are on), the detection sensor 8 transmits an unauthorized intrusion detection signal Sa with a unique address of each detection sensor 8 to the outside. The unauthorized intrusion detection signal Sa corresponds to the detection signal.

  The camera 9 is disposed at a position where it is possible to photograph unauthorized intrusion of a third party into the house 2 and is driven and controlled by the abnormality monitoring device 7. The camera 9 is arranged in pairs with each detection sensor 8. In this example, a camera 9a installed outdoors for the door opening / closing sensor 8a and a camera 9b installed indoors for the infrared sensor 8b are provided. is there. Upon receiving a shooting start command from the abnormality monitoring device 7, the camera 9 starts shooting, performs shooting for a predetermined time (for example, 1 minute), and outputs the video data to the abnormality monitoring device 7.

  When receiving the unauthorized intrusion detection signal Sa from the detection sensor 8, the abnormality monitoring device 7 enters an unauthorized intrusion detection state and determines that there has been an unauthorized intrusion in the house 2. At this time, the abnormality monitoring device 7 refers to the unique address attached to the unauthorized intrusion detection signal Sa to determine from which detection sensor 8 the unauthorized intrusion detection signal Sa is transmitted, and the destination of the unauthorized intrusion detection signal Sa Is detected, an imaging start command is output to the camera 9 paired with the detection sensor 8 to cause the camera 9 to image the site of unauthorized intrusion. For example, when receiving the unauthorized intrusion detection signal Sa from the door opening / closing sensor 8a, the abnormality monitoring device 7 causes the camera 9a to perform imaging, and when receiving the unauthorized intrusion detection signal Sa from the infrared sensor 8b, causes the camera 9b to perform imaging.

  When the abnormality monitoring device 7 receives the unauthorized intrusion detection signal Sa from the detection sensor 8, the abnormality monitoring device 7 outputs the abnormality occurrence signal Sb to the controller 5 in synchronization with the camera 9 starting the photographing, and there is an unauthorized intrusion into the house 2. To the controller 5. When the controller 5 receives the abnormality occurrence signal Sb, the controller 5 is in a restricted state in which the electric lock 6 cannot be freely unlocked. In this restricted state, even if ID verification is established between the electronic key 3 and the controller 5, the lock is locked. The electric lock 6 in the state is not unlocked.

  The monitor 10 is attached to the outer wall near the entrance door 4 of the house 2 and is driven and controlled by the abnormality monitoring device 7. The monitor 10 displays a nameplate in a normal state, and when the resident returns to the house 2 where unauthorized intrusion is detected, the video data D captured by the camera 9 is input from the abnormality monitoring device 7 and the video data Can be broadcast. When the controller 5 recognizes that ID verification is established when the controller 5 is in the restricted state and the electric lock 6 is in the locked state, the controller 5 outputs an ID verification establishment signal Sc to the abnormality monitoring device 7. When the abnormality monitoring device 7 is in the alert mode and receives the ID verification establishment signal Sc from the controller 5, the abnormality monitoring device 7 outputs a reproduction start signal Sd to the monitor 10 in order to broadcast the video data D captured from the camera 9 on the monitor 10.

  The abnormality monitoring device 7 outputs a reproduction start signal Sd to the monitor 10 so that the reproduction initial screen 12 shown in FIG. On the reproduction initial screen 12, a list of detection sensors 8 that have detected unauthorized intrusion is displayed. The monitor 10 is a touch panel type, and by touching the display unit 13 of the detection sensor 8, it is possible to select a broadcast video to be broadcast on the monitor 10. The abnormality monitoring device 7 displays on the monitor 10 a simplified diagram 14 of the house 2 shown in FIG. 3 which simultaneously displays the position of the detection sensor 8 selected on the monitor 10, and then video data corresponding to the selected detection sensor 8. D is sent to the monitor 10, and the illegal intrusion video is broadcast on the monitor 10.

  The monitor 10 is provided with a push button type release switch 10a for releasing the restricted controller 5 to the normal state. When the release switch 10a is pressed, the monitor 10 outputs a release command signal Se to the abnormality monitoring device 7. When the failure monitoring device 7 receives the release command signal Se from the monitor 10, the abnormality monitoring device 7 determines that the restricted state of the controller 5 should be released, and outputs a release permission signal Sf to the controller 5. When the controller 5 inputs the release permission signal Sf when the controller 5 is in the restricted state and the electric lock 6 is in the locked state, the controller 5 unlocks the electric lock 6 on the condition that the ID verification is established at that time. The release switch 10a corresponds to release means, and the display unit 13 corresponds to selection means.

Next, the operation of the security system 1 will be described with reference to the sequence chart of FIG.
When all the residents go out and leave the house 2, the residents press the warning mode setting switch 7 a of the abnormality monitoring device 7. After the switch operation, the entrance door 4 is opened and closed, the resident goes out, the resident with the electronic key 3 goes out of the communication area of the antenna 5a, and the electric lock 6 is locked. Monitor unauthorized intrusion of a third party into the house 2. In this state, the abnormality monitoring device 7 can receive a signal from the detection sensor 8, and the camera 9 enters an operation standby state.

  Here, it is assumed that when the security system 1 is in the alert mode, the thief attempts an unauthorized entry into the house 2. If a thief opens the window glass 11 illegally and the door opening / closing sensor 8a detects this, the door opening / closing sensor 8a transmits an unauthorized intrusion detection signal Sa. Further, when the theft goes into the house 2 and the infrared sensor 8b detects this, the infrared sensor 8b also transmits an unauthorized intrusion detection signal Sa. In this example, both the door opening / closing sensor 8a and the infrared sensor 8b are in the sensing state and transmit the unauthorized intrusion detection signal Sa.

  When receiving the unauthorized intrusion detection signal Sa, the abnormality monitoring device 7 determines that the theft has entered the house 2 and outputs a photographing start command to the camera 9 to cause the camera 9 to photograph the intrusion site. Then, the abnormality monitoring device 7 takes in the video data D captured by the camera 9 and stores it in the internal RAM. In this example, since both the door opening / closing sensor 8a and the infrared sensor 8b detect unauthorized intrusion, the abnormality monitoring device 7 outputs a shooting start command to both the cameras 9a and 9b, and the two cameras 9a and 9b. Let's take a picture of the intrusion site.

  When the abnormality monitoring device 7 receives the unauthorized intrusion detection signal Sa, the abnormality monitoring device 7 outputs an abnormality occurrence signal Sb to the controller 5 in synchronization with the intrusion site photographing by the camera 9. When the controller 5 receives the abnormality occurrence signal Sb, the controller 5 determines that a thief has illegally entered the house 2 and enters a restricted state where the electric lock 6 cannot be freely unlocked and unlocked. In this restricted state, even if the resident who owns the electronic key 3 returns home after leaving the electric lock 6 in the locked state and the ID verification is established between the electronic key 3 and the controller 5, the controller 5 The lock 6 is maintained in the locked state and is not unlocked.

  Subsequently, it is assumed that the resident returns home for a while after the theft has entered the house 2 illegally. At this time, when the resident who owns the electronic key 3 enters the communication area of the antenna 5 a, the controller 5 performs ID verification with the electronic key 3. Here, since the controller 5 is in a restricted state, the electric lock 6 is not unlocked even if ID verification is established between the controller 5 and the electronic key 3. Therefore, since the resident does not enter the house 2 and is not released even though the electric lock 6 is supposed to be released, the resident knows that the theft has entered the house 2 and does not enter the house 2 carelessly. .

  When the ID verification is established in the restricted state, the controller 5 does not permit the unlocked electric lock 6 to be unlocked and outputs an ID verification establishment signal Sc to the abnormality monitoring device 7. When the abnormality monitoring device 7 inputs the ID verification establishment signal Sc when it is in an unauthorized intrusion detection state, the abnormality monitoring device 7 outputs a reproduction start signal Sd to the monitor 10 and monitors the reproduction initial screen 12 (see FIG. 2) instead of the nameplate. To display. When unauthorized intrusion is detected by both the door opening / closing sensor 8a and the infrared sensor 8b as in this example, the names of these two sensors are displayed on the reproduction initial screen 12.

  Then, among the display units 13 of the detection sensors 8 displayed on the monitor 10, the resident touches the display unit 13 of the video to be broadcasted, so that the broadcast video is selected. When this operation is performed, a simplified diagram 14 (see FIG. 3) showing where the detection sensor 8 is in the house 2 is broadcast on the monitor 10, and thereafter, the camera 9 that forms a pair with the detection sensor 8. The captured video is broadcast on the monitor 10. Therefore, by watching the video broadcast on the monitor 10, the resident can check what is the cause of the reaction of the detection sensor 8, and can recognize how the intrusion has occurred from which location in the house 2. It becomes.

  On the other hand, even if the detection sensor 8 reacts and photographing with the camera 9 is performed, for example, a ball or the like hits the window glass 11, and the door opening / closing sensor 8a reacts due to the shaking, so The security system 1 may operate without causing unauthorized intrusion. In this case, if the resident who returns home looks at the monitor 10, it can be seen that the electric lock 6 is in a restricted state, not because of unauthorized intrusion, so the resident checks the monitor 10 and determines that there is no abnormality in the house 2. Then, the release switch 10a of the monitor 10 is pushed.

  Then, the monitor 10 outputs a release command signal Se to the abnormality monitoring device 7, and the abnormality monitoring device 7 outputs a release permission signal Sf to the controller 5 when the release command signal Se is input from the monitor 10. When the controller 5 inputs the release permission signal Sf when the electric lock 6 is locked and the electric lock 6 is locked, the controller 5 determines whether or not the ID collation with the electronic key 3 is established at that time. If the verification is established, the electric lock 6 is unlocked and the security system 1 is switched to the release mode. Therefore, since the resident confirms the safety in the house 2 and unlocks the electric lock 6 and enters the house 2, the resident can enter the house 2 after confirming the safety in the house 2.

  In addition, after setting the security system 1 in the alert mode, the resident may come home in a state where the detection sensor 8 is not responding, that is, in a state where no unauthorized intrusion into the house 2 has occurred. In this case, when the ID verification with the electronic key 3 is established, the controller 5 unlocks the locked electric lock 6 and unlocks completion signal Sg indicating that the electric lock 6 has been unlocked (see FIG. 1) is output to the abnormality monitoring device 7. When the abnormality monitoring device 7 receives the unlocking completion signal Sg, the abnormality monitoring device 7 releases the warning mode based on the signal, and switches the operation mode of the security system 1 to the release mode.

  In this example, when all the residents go out and leave the house 2, the security system 1 is set to the warning mode by operating the warning mode setting switch 7a of the abnormality monitoring device 7, and in this state, the detection sensor When 8 detects unauthorized intrusion, the camera 9 captures the site of unauthorized intrusion and restricts the unlocking of the electric lock 6. Even if the resident returns home and tries to open the entrance door 4, the entrance door 4 cannot be opened because the electric lock 6 is not locked, and the on-site image of unauthorized intrusion photographed by the camera 9 is broadcast on the monitor 10. Is done.

  Therefore, since the electric lock 6 is not locked, the resident does not enter the house 2, and thus the resident knows that the theft has entered the house 2 and does not enter the house 2 carelessly. Therefore, a dangerous situation in which the resident encounters the theft can be avoided, and the security of the resident who has returned home is ensured. In addition, since the video shot by the camera 9 is broadcast on the monitor 10, it is possible to check what is the cause of the reaction of the detection sensor 8, and it is also possible to check how and where the unauthorized intrusion occurred. It becomes. Therefore, it is possible to quickly and accurately take subsequent actions such as reporting to a security company.

According to the configuration of the above embodiment, the following effects can be obtained.
(1) When the security system 1 detects unauthorized entry into the house 2, the unlocking of the locked electric lock 6 is restricted, and the electric lock 6 is unlocked even if the ID verification of the electronic key 3 is established. It will be unlocked. Therefore, the resident cannot open the entrance door 4, and it is possible to prevent the resident from inadvertently entering the house 2 where a third party such as a theft may be present, and to ensure the security of the resident. Can do. In addition, since the video taken by the camera 9 when the security system 1 detects an unauthorized intrusion is broadcast on the monitor 10 when the resident returns home, it is necessary to confirm how and where the unauthorized intrusion occurred. And theft can be dealt with quickly and accurately.

  (2) When the security system 1 detects unauthorized intrusion, both the unlocking of the electric lock 6 and the broadcast of the unauthorized intrusion site on the monitor 10 are both performed. A resident can be notified more reliably.

  (3) When the camera 9 is installed so as to form a pair with each detection sensor 8 and the plurality of detection sensors 8 detect unauthorized intrusion, an image of the unauthorized intrusion site corresponding to each detection sensor 8 is displayed on the monitor 10. Each can be aired. Therefore, unauthorized intrusion can be monitored over a wide area of the house 2, and the security of the security system 1 can be improved. In addition, photographing an unauthorized intrusion site with a plurality of cameras 9 corresponding to each detection sensor 8 and broadcasting it on the monitor 10 means notifying the method of unauthorized intrusion in a format corresponding to each detection sensor 8. Become. Therefore, it is possible to notify the resident more reliably from where in the wide area of the house 2 and by what means, the subsequent countermeasures can be performed more quickly and appropriately.

  (4) When a plurality of detection sensors 8 detect unauthorized intrusion and the unauthorized intrusion site is photographed by a plurality of cameras 9, by operating the monitor 10 with a touch panel, it is possible to select an image to be broadcast on the monitor 10. A resident can freely select an image to be broadcast on the monitor 10.

  (5) When the warning mode setting switch 7a of the abnormality monitoring device 7 is pressed, the security system 1 is set from the release mode to the warning mode, and the intrusion into the house 2 is monitored. Therefore, when there is a resident in the house 2 normally, if the operation mode of the security system 1 is set to the release mode, a situation in which the resident is apologized and the resident is detected as a theft is less likely to occur, and the usability as a system is improved. .

  (6) When the unlocked switch 10a of the monitor 10 is pressed while the locked electric lock 6 is in the restricted state, the electric lock 6 is unlocked on condition that the ID verification of the electronic key 3 is established, and the security system 1 Returns to release mode. Accordingly, the resident himself can reset the security system 1 and the system is highly versatile.

  (7) Since the monitor 10 reproduces both the intrusion recorded video and the nameplate, the number of monitors can be reduced as compared with the case where monitors are prepared for each, and the system configuration can be simplified.

In addition, you may change the said embodiment not only to the said structure but to the following aspects.
The detection order of the detection sensors 8 that can be regarded as unauthorized intrusion is stored in the ROM (storage means) of the abnormality monitoring device 7, and the intrusion occurs when the detection order of the detection sensors 8 is in that order. A configuration in which the abnormality monitoring device 7 determines may be adopted. For example, in the case of the embodiment, when the sensors react in the order of the door opening / closing sensor 8a and the infrared sensor 8b, it may be determined that an unauthorized intrusion has occurred.

  The notification means is not limited to the monitor 10 and may be a buzzer, for example. At this time, the notification sound may be changed depending on the detection sensor 8 that has reacted. For example, if an unauthorized intrusion is detected by the door opening / closing sensor 8a, an alarm sound “Piece” sounds, and if an unauthorized intrusion is detected by the infrared sensor 8b. A notification sound “beep” may be generated.

  The setting of the security system 1 to the warning mode is not limited to the switch operation of the warning mode setting switch 7a as a condition. For example, the security system 1 may be set in the alert mode when all the residents have the electronic key 3 and the controller 5 determines that all the residents have gone out based on wireless communication with the electronic key 3.

  The electronic key 3 is not limited to a key that is automatically locked or unlocked when approaching the entrance door 4, for example, a lock button and an unlock button are provided on the key body, and each button is pressed to lock or unlock the door. A radio wave key may be used.

  The restriction state of the controller 5 is not limited to the configuration that is released by operating the release switch 10a of the monitor 10. For example, the timer may be set when the resident returns home and ID verification is established between the electronic key 3 and the controller 5, and the restriction state may be canceled when the timer expires.
