Description

  The present invention relates to a security system that detects an intruder invading a house by using an intrusion detection device, and performs threatening and reporting.

  Conventionally, when an abnormality occurs in a security area in a security system, a control device installed in the security area sounds an alarm sound and notifies the security center via a communication line. When the security center receives this abnormality report, it reports the location of the abnormality and the content of the abnormality to the coping person, and the coping person rushes to the corresponding security area and takes an appropriate action.

  Abnormalities in the security area include fire abnormalities, detection of people in the security set, intrusion abnormalities such as opening of doors and windows, and device abnormalities in which the devices constituting the security system have failed. For example, there are so-called passive infrared sensors that detect infrared rays emitted by the human body and detect the presence or absence of humans, and infrared beam sensors that project and receive infrared beams at locations where people pass to detect infrared rays. Various intrusion sensors such as a human sensor for detecting the intrusion of a person and a magnet sensor for detecting opening / closing of a window or a door are arranged. These intrusion sensors detect intrusion abnormalities. The detection signal from the intrusion sensor is transmitted to the control device by wired or wireless communication.

  If the control device wants to receive this detection signal or is a detection signal from an intrusion sensor, if the operation mode is in the security set state, it will sound an alarm sound or threaten it to the security center via the communication line. To do. On the other hand, if the operation mode is the security release state, the control device does not treat it as an abnormality even if it receives a detection signal from the intrusion sensor, and does not output or report an alarm sound.

  That is, the intrusion sensor does not distinguish between an intruder and a regular user of the security area, and sends a detection signal regardless of the operation mode when a person is detected. The control device determines whether there is an intrusion abnormality according to the operation mode.

  When receiving a fire detection signal or an equipment abnormality signal, the control device notifies the security center regardless of the operation mode, unlike the case of an intrusion abnormality.

Patent Document 1 discloses a security system that, when an intrusion warning sensor detects an intruder, blinks a lighting fixture and threatens with light as well as alarm sound.
JP 2003-16542 A

  In the conventional security system, when there is an intruder in the security area, the threat or sound is reported by sound or light. That is, it does not have a function to prevent a suspicious person from entering. For this reason, when an intrusion is detected, the window may be broken or the door key may be broken.

  Therefore, in view of the above, an object of the present invention is to provide a security system that can prevent a suspicious person from entering in advance by actively informing that security is being performed.

  The present invention comprises an intrusion detection device having an intruder detector for detecting the presence or absence of an intruder, and a control device capable of communicating with the intrusion detection device. It is a security system that notifies the control device when the presence of a person is detected, and the control device issues an alarm. Then, the control device performs switching between the security set state and the security release state, and externally indicates that the intrusion detection device is in either the security set state or the security release state according to communication from the control device. A display unit for informing is provided.

  Since the intrusion detection device is equipped with a display unit, the display unit will be installed in the vicinity of the window or door, and will be visible to the intruder who is about to enter and guarding the intruder. Can be appealed and the intrusion can be discouraged.

  Then, the control device switches the operation mode between the security set state and the security release state, and transmits information on the operation mode switched to the intrusion detection device. The intrusion detection device detects an intruder according to the operation mode. In the security set state, when the intruder detector detects the presence of an intruder, the control device issues an alarm. In the security release state, even if the intruder detector detects the presence of an intruder, the control device does not issue an alarm.

  The display unit displays in different display forms depending on the operation mode. That is, although the display form of the security set state is different from the display form of the security release state, the display by the display unit is performed in any state. Thereby, it can be assumed that the intrusion detection device operates and is being guarded against the intruder, and the intrusion can be prevented. On the other hand, for the user, the current operation mode can be confirmed by the display, and forgetting to set or forget to release can be prevented.

  Therefore, since the display unit only needs to be seen from the outside, the intruder detector is installed indoors, and the display unit is arranged at a position where it can be seen from the outside. By making the display unit separable from the intruder detector, the display unit can be installed at a position that is easy to see from the outdoors.

  The display unit can change each display form of the security set state and the security release state. An operation unit may be provided in the intrusion detection device to change the display form, or an operation unit for setting the display form in the display unit may be provided in the control device. When the display form is set in the control device, this information is transmitted to the intrusion detection device, and the display form is changed. In this way, by making it possible to change the display form, it is possible to display that the security release state is set so that the intruder does not know. Therefore, even in the security release state, the intruder cannot easily perceive that the intruder is in that state, an intrusion prevention effect is obtained, and the reliability of the security system is improved.

  According to the present invention, by providing the display unit, it can be positively displayed that the guard is in operation, and the intruder can be prevented from entering. Therefore, intrusion can be prevented before the intruder breaks the windows and doors, and a security system with a high security effect can be realized.

  In addition, it displays in different forms not only in the security set state but also in the security release state, so that intruders can recognize that they are being guarded, and the user should check the current operation mode Can do.

The controller 3 and the security center 4 are connected via a communication line 5 such as a telephone line so that bidirectional communication is possible.

  As an intrusion detection device, a magnet sensor transmitter 1 that detects opening / closing of a window or a door and a human sensor transmitter 2 that detects movement of a person are used. The magnet sensor transmitter 1 is installed on the indoor side near the window 6 and the door 7. The human sensor transmitter 2 is installed in a hallway, a staircase, an indoor wall or ceiling. The magnet sensor transmitter 1 and the human sensor transmitter 2 notify the controller 3 by wireless communication when detecting the presence of an intruder. When the controller 3 detects intrusion into the security area, the controller 3 sounds an alarm sound to intimidate the intruder and notifies the security center 4 via the communication line 5.

  FIG. 2 shows a block configuration of the controller 3. The controller 3 includes an operation unit 10, a display unit 11, a notification unit 12, a reception unit 13, a transmission unit 14, a notification unit 15, and a control unit 16.

The reporting unit 12 sends an abnormality report to the security center 4 via the communication line 5 and receives information from the security center 4. The receiving unit 13 receives radio signals transmitted from the magnet sensor transmitter 1 and the human sensor transmitter 2 via the antenna 17. The transmission unit 14 transmits a switching signal for switching to the security set state or the security release state to the magnet sensor transmitter 1 and the human sensor transmitter 2 via the antenna 17 by a predetermined radio signal. The notification unit 15 sounds an alarm sound to threaten the intruder. The control unit 16 includes a microcomputer that controls the above-described units, and peripheral circuits such as a memory and a clock.

  FIG. 3 shows a block configuration of the magnet sensor transmitter 1. The magnet sensor transmitter 1 includes a magnet switch unit 20, a magnet I / F unit 21, a transmission unit 22, a reception unit 23, a display unit 24, an operation unit 25, a control unit 26, and a battery 27. Composed.

  The magnet switch unit 20 is disposed in the vicinity of the window 6 and the door 7 and outputs a detection signal to the control unit 26 when the opening of the window 6 and the door 7 is detected. The magnet I / F unit 21 is an interface circuit that communicates with the magnet switch unit 20, receives a detection signal from the magnet switch unit 20, and outputs the detection signal to the control unit 26. The transmission unit 22 converts the detection signal into a wireless signal and wirelessly transmits the signal from the antenna 28 to the controller 3. The receiving unit 23 receives a radio signal such as an operation mode switching signal and a display setting signal for the display unit 24 from the controller 3. The display unit 24 is composed of LEDs and performs display according to the operation mode. The operation unit 25 performs display setting of the display unit 24 and the like. The control unit 26 includes a microcomputer and peripheral circuits such as a memory and a clock, and controls the above-described units. The battery 27 supplies power to them. The display unit 24 is separate from the housing 29 that houses the operation unit 25, the control unit 26, and the like, and is connected by a cable or the like. Therefore, the display unit 24 can be installed in another place away from the housing 29.

  FIG. 4 shows a block configuration of the human sensor transmitter 2. The human sensor transmitter 2 includes a human sensor unit 30, a transmission unit 31, a reception unit 32, a display unit 33, an operation unit 34, a control unit 35, and a battery 36.

  The human sensor unit 30 includes a passive infrared sensor that captures the movement of a person as a change in heat, and outputs a detection signal to the control unit 35 when the presence of a person is detected. The transmission unit 31 converts the detection signal into a wireless signal and wirelessly transmits the signal from the antenna 37 to the controller 3. The receiving unit 32 receives wireless signals such as an operation mode switching signal and a display setting signal for the display unit 33 from the controller 3. The display part 33 is comprised with LED and performs the display according to the operation mode. The operation unit 34 performs display setting of the display unit 33 and the like. The control unit 35 includes a microcomputer, peripheral circuits such as a memory and a clock, and controls the above-described units. The battery 36 supplies power to them. The human sensor 30 is not limited to a passive infrared sensor, and may be any sensor that detects the presence or absence of a person in the security area, such as an ultrasonic sensor, an infrared beam sensor, or a camera. The display unit 33 is provided in a housing 38 that houses the operation unit 34, the control unit 35, and the like.

  Next, the operation | movement according to the operation mode of a security system is demonstrated. When the operation unit 10 of the controller 3 is switched to the security set state or the security release state, the control unit 16 outputs a switching signal to the transmission unit 14, and the transmission unit 14 transmits the magnet sensor transmitter 1 and the human sense. A switching signal is wirelessly transmitted to the sensor transmitter 2.

  In the magnet sensor transmitter 1, when the receiving unit 23 receives a switching signal from the controller 3, the control unit 26 executes an operation mode corresponding to the switching signal. That is, the control unit 26 wirelessly transmits the detection signal to the controller 3 by the transmission unit 22 when the detection signal is input from the magnet switch unit 20 in the security set state. On the other hand, even if the magnet switch unit 20 detects the opening / closing of the window 6, the door 7, etc. and outputs a detection signal when in the security release state, the control unit 26 does not wirelessly transmit the detection signal to the controller 3. . Further, according to the display setting of the operation unit 25, the display unit 24 displays the operation mode.

  In the human sensor transmitter 2, when the receiving unit 32 receives a switching signal from the controller 3, the control unit 35 executes an operation mode corresponding to the switching signal. That is, when the control unit 35 is in the security set state and receives a detection signal from the human sensor unit 30, the control unit 35 wirelessly transmits the detection signal to the controller 3 by the transmission unit 31. On the other hand, even when the human sensor unit 30 detects a person and outputs a detection signal in the security release state, the control unit 35 does not wirelessly transmit the detection signal to the controller 3. Further, the display unit 33 displays the operation mode according to the display setting of the operation unit 34.

  As described above, the intrusion detection device does not wirelessly transmit the detection signal to the controller 3 even when the door 7 or the like is frequently opened or closed or the presence of a person is detected when in the alert release state. Therefore, communication traffic can be reduced and unnecessary communication is reduced, so that the battery life can be extended.

  And the display part 24 of the magnet sensor transmitter 1 is installed in the position which can be seen from the exterior, such as the window 6. FIG. The display unit 24 not only displays that it is in the security set state, but also displays it in the security release state. In any state, it can be visually recognized from the outside that some display is made on the display unit 24. Therefore, an intruder who does not know the actual situation can be informed that the guard is being guarded, and the effect of stopping the intrusion can be exhibited.

  FIG. 5 shows the installation status of the magnet sensor transmitter 1. The housing 29 of the magnet sensor transmitter 1 is attached to a wall near the window. The display unit 24 protrudes from the housing 29 and is located at a position facing the window 6. It is installed so that it can be seen clearly. As described above, the intrusion detection device is installed indoors by adopting a structure in which the display unit 24 is protruded from the housing 29 or a structure in which the display unit 24 can be installed separately from the housing 29. It is possible to inform the person who is outdoors that the guard is set.

  In general, the intrusion detection device is installed inside the security area, for example, in a house where the window 6 is closed so that the intruder is not destroyed before intrusion. Here, by adopting a structure in which the housing 29 and the display unit 24 can be installed at different positions, it is possible to install only the display unit 24 while protecting the intrusion detection device itself from an intruder.

  The display units 11 and 33 of the human sensor transmitter 2 and the controller 3 may also be separable from the housing 38. If the display units 11 and 33 are installed on an outdoor wall or the like, they can be seen from the outside. By this, it can display that it is guarding from anywhere.

  Here, the display form of the display units 24 and 33 will be described with reference to FIG. The display units 24 and 33 are configured by two LEDs. In the security release state, the LEDs blink alternately. In the security set state, the blinking operation is repeated in the order of left LED on, both LED on, right LED on, both LED off, and left LED on again.

  By performing blinking display of LEDs on the display units 24 and 33, it is possible to actively inform the intruder that the intrusion detection device is installed. In addition, the user can be notified of whether the user is in the security set state or in the security release state by the blinking state of the LED. This makes it possible to switch to the security set state without forgetting when going out, and to reliably switch to the security release state when returning home, eliminating erroneous operation mode switching and malfunctioning. Can be prevented.

  In addition, the display mode of the operation mode in the display units 24 and 33 such as the blinking display of the LED for the security set state or the security release state can be freely changed by setting from the operation units 25 and 34. Therefore, even an intruder who is familiar with the security system can prevent the present display form from indicating whether the security set state or the security release state. That is, the intruder knows only that the intrusion detection device is installed and operating.

  The user may set the display form from the controller 3 instead of directly setting the display form from the operation units 25 and 34 of the intrusion detection device. That is, in the operation unit 10 of the controller 3, the user sets a desired display form for each intrusion detection device. A display setting signal corresponding to the setting content is wirelessly transmitted by the transmitter 14 to the magnet sensor transmitter 1 or the human sensor transmitter 2. When the magnet sensor transmitter 1 or the human sensor transmitter 2 receives the display setting signal, the display units 24 and 33 perform display in a display form according to the security set state or the security release state according to the display setting. In addition, the control parts 26 and 35 memorize | store the setting content as needed.

  In this way, the operation units 25 and 34 for setting the display form in the intrusion detection device are not necessary, and the intrusion detection device can be manufactured at a lower cost. Further, it is not necessary to perform display setting for each apparatus when the intrusion detection apparatus is installed, and the display setting of each intrusion detection apparatus can be collectively performed by the controller 3, which facilitates the setting work. In particular, when a large number of intrusion detection devices are installed, the setting work can be omitted, and the workability during installation is improved.

  As described above, by actively displaying by the intrusion detection device, not only can the fact that it is actually being guarded, but it is as if it is guarded in spite of being in the security unlocked state. You can produce. An intruder can be informed that the house is equipped with a security system, and if an intruder enters, an alarm will sound and be intimidated and reported to the security center. There is a survey result that if an intruder such as a burial nest is found to be a house that is difficult to invade, it will give up and not forcibly enter. This makes it possible to discourage intrusion, and a function to prevent intrusion can be obtained as a security system.

  In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of the present invention. The controller and the intrusion detection device such as the magnet sensor transmitter and the human sensor transmitter perform wireless communication. As a wireless system, specific low power wireless, infrared, wireless LAN, or Bluetooth (registered trademark) may be used. The controller and the intrusion detection device may be connected by a cable or the like so that wired communication is possible. Further, these wireless communication and wired communication may be arbitrarily combined depending on the positional relationship between the intrusion detection device and the controller.

  In the display unit, the display form using two LEDs is shown, but one LED may be used. In this case, the flashing period is changed by fast flashing in the security release state, for example, 0.5 second ON / 0.5 second OFF, and slow flashing in the security setting state, for example, 0.5 second ON / 2 second OFF. Thus, different display forms are used. Two or more LEDs may be used, and further, other display elements such as a liquid crystal display element, an EL (electroluminescence) element, and a lamp may be used instead of the LED. Further, the display unit may have a structure in which the casing of the intrusion detection device itself emits light so as to emphasize the presence of the intrusion detection device. The display unit may not only display in a form corresponding to the operation mode, but also may display the information to a third party, for example, in an irregular form when an intruder is detected.
