Description

  The present invention generally relates to an intrusion warning system, and more particularly, to a security system that detects an intruder entering a building such as a house and intimidates and reports by an intrusion detection device.

  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, human detection during security operation setting, intrusion abnormalities such as door opening and window opening, and device abnormalities that cause failures in the devices constituting the security system.

  In addition, there are passive infrared sensors that detect infrared rays emitted by the human body to detect the presence of people, and infrared beam sensors that detect and block infrared rays by projecting and receiving infrared beams at locations where people pass. Various intrusion sensors such as a human sensor for detecting the intrusion itself 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 of the intrusion sensor is transmitted to the control device by wired or wireless communication.

  In the case of an intrusion abnormality in which the control device receives the detection signal of the intrusion sensor, the response varies depending on the operation mode. When in the operation mode security setting state, the control device sounds an alarm sound to intimidate or sends an external report to the security center via a communication line. When 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 an alarm sound or report. In other words, 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 detecting the presence of a person. The control device determines whether there is an intrusion abnormality according to the operation mode.

  On the other hand, when the control device receives a fire detection signal or a device abnormality signal, it is configured to notify the security center externally regardless of the operation mode, unlike the case of an intrusion abnormality.

Japanese Patent Laid-Open No. 2003-16542 (Patent Document 1) discloses that when an intrusion warning sensor detects an intruder, the lighting apparatus blinks and an alarm sound is generated from an alarm sound generation unit, and the light and sound enter. An intrusion warning device that threatens a person is disclosed.
JP 2003-16542 A

  In the conventional intrusion warning device, when there is an intruder in the security area, the alarm sound or light is used to threaten or report to the outside. That is, it does not have a function to prevent a suspicious person from entering. Therefore, when an intrusion is detected, there are many cases where the window has already been broken or the door key is broken.

  In addition, unlike such conventional intrusion warning devices, a security system can be considered to prevent intrusion damage by suspicious persons by displaying the fact that the guard is being seen from the outside. If the message “in security” is displayed, the power consumption increases.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an intrusion warning system that can effectively notify a suspicious person that the person is being guarded or guarded, and can prevent intrusion damage.

  An intrusion warning system according to the present invention includes a first detection device that detects a person who enters a building, a second detection device that detects a person approaching the building, and a first detection device that is installed in the building. A control device capable of communicating with the detection device; The first detection device communicates with the control device when an intruder is detected. The second detection device includes a notification unit that notifies the approaching person when the approaching person is detected.

  In the intrusion warning system according to the present invention, when the second detection device detects a person approaching the building from outside the building, the approaching person can be informed that the person is approaching the warning. For this reason, it can be shown that it is guarding the person who tries to invade the building, and the intrusion can be discouraged.

  In the intrusion warning system of the present invention, the notification unit includes a notification sound generation unit that generates a sound to notify an approaching person, and when the second detection device detects the approaching person, the notification unit generates a sound. It is preferable to notify the approaching person that he is on alert.

  Moreover, in the intrusion warning system of this invention, an alerting | reporting part contains the display part arrange | positioned in the position where an approaching person can be seen, and when the 2nd detection apparatus detects an approaching person, an alerting | reporting part is alerting It is preferable to notify the approaching person by displaying.

  Furthermore, in the intrusion warning system according to the present invention, the notification unit includes a first notification sound generation unit that generates a relatively small notification sound, and a second notification sound generation unit that generates a relatively large notification sound. When the second detection device detects the approaching person, the first notification sound generating unit generates a relatively small sound to notify the approaching person of being alerted, and the first detection apparatus When the intruder is detected or when the first detection device receives an alarm instruction from the control device, the second notification sound generator generates a relatively loud sound to threaten the intruder. preferable.

  In this case, when a person who approaches the building from outside the building is detected by providing a high / low volume sound generator, it is informed that the guard is in low volume and an intruder in the building is detected. Alternatively, when an alarm instruction is received from the control device, the alarm notification can be performed with a large volume. As a result, a warning sound can be generated from the second detection device separately from the warning sound generated by the control device, so that a stronger threat can be given to the intruder.

  In the intrusion warning system according to the present invention, the control device can communicate with the second detection device, and the second detection device detects the approaching person while the approaching person is detected at a predetermined first time interval. Preferably, when a certain signal is transmitted to the control device and the second detection device does not detect an approaching person, a signal without an approaching person is transmitted to the control device.

  In this case, when the second detection device detects a person approaching the building from the outside of the building, the second detection device notifies the control device of a signal that there is an approaching person, and approaches at regular intervals while detecting the approaching person. Report the presence of a person. Further, when the person approaching the building from the outside of the building is not detected, a signal indicating no approaching person is notified to the control device. Therefore, when the control device receives a signal with an approaching person, the control device determines that the signal with an approaching person is received within a predetermined time interval until the signal without an approaching person is received. If no signal with an approaching person is received within the time interval, it can be determined that the second detection device has been broken, and an alarm instruction and external notification can be made in the same manner as when there is an intruder in the building. . Thereby, a more secure security system can be realized.

  Further, in this case, when the control device does not receive the approaching presence signal or the approaching absence signal even after the second time longer than the first time has elapsed after receiving the approaching presence signal, It is preferable to intimidate the intruder by generating a sound.

  In the intrusion warning system of this invention, it is preferable that the 1st detection apparatus and the 2nd detection apparatus are integrated.

  In the intrusion warning system of this invention, it is preferable that a 2nd detection apparatus contains a passive infrared sensor.

  In this case, the passive infrared sensor can capture a human movement as a change in heat.

  Moreover, in the intrusion warning system of this invention, it is preferable that a 2nd detection apparatus contains an ultrasonic sensor.

  In this case, the ultrasonic sensor can measure the distance to a person by generating an ultrasonic wave and measuring the time until the ultrasonic wave is reflected and returned.

  Furthermore, in the intrusion warning system of this invention, it is preferable that a 2nd detection apparatus contains a reflection type optical sensor.

  In this case, the reflection type optical sensor can measure the presence or absence of an approaching person by generating light such as infrared rays and measuring whether or not the light is reflected and returned.

  Furthermore, in the intrusion warning system of this invention, it is preferable that a 2nd detection apparatus contains a transmissive | pervious optical sensor.

  In this case, the transmissive optical sensor generates light such as infrared rays, and the light is received by a separate light receiving unit, and detects that the approaching person blocks the light, thereby detecting the presence or absence of the approaching person. can do.

  In the intrusion warning system of this invention, it is preferable that a 2nd detection apparatus contains an image recognition sensor.

  In this case, the image recognition sensor can detect the presence or absence of an approaching person by performing image recognition processing on the camera video.

  According to the present invention, the person approaching the building can be actively informed that the person is approaching the guard or guarding. Therefore, a highly secure security system can be realized. In addition, only when there is a person approaching the building, it is possible to notify that it is being alerted or guarded by generating or displaying an alarm sound. In particular, when the second detection device is driven by a battery, it is possible to operate for a long time, and usability is improved.

  FIG. 1 is a diagram showing an overall configuration of a security system as one embodiment of an intrusion warning system according to the present invention.

  As shown in FIG. 1, the security system 1 as an intrusion warning system detects opening and closing of windows and doors as a first detection device in order to detect a person who enters a security area in a building such as a house.

In particular, in the human sensor transmitter 20, the sensor installation direction, the lens of the sensor, and the like are adjusted so that an intruder can detect a person approaching the window or door trying to enter the building. Has been.

  FIG. 2 is a block diagram showing a schematic configuration of a controller as a control device constituting the security system of FIG.

  As shown in FIG. 2, the controller 30 includes an operation unit 31, a display unit 32, a notification unit 33, a reception unit 34, a transmission unit 35, a notification unit 36, a control unit 37, and an antenna 38. Composed.

  The operation unit 31 includes operation keys, a card reader, and the like. A legitimate user or cooperator who is allowed to enter the security area operates the operation unit 31 to perform a switching operation and various settings for changing the operation mode from the security release state to the security setting state or vice versa. Do. The display unit 32 is composed of a light emitting diode (LED) and a liquid crystal display (LCD), and the security setting state of the whole and each detection device, such as a security setting state and a security release state, whether or not an abnormality has occurred, equipment maintenance information, etc. Is displayed. The reporting unit 33 reports an abnormality to the security center 40 via the communication line 50 and receives information from the security center 40.

  The receiving unit 34 receives wireless signals transmitted from the magnet sensor transmitter 10 and the human sensor transmitter 20 via the antenna 38. The transmission unit 35 transmits a control signal instructing start or stop of alarm notification to an alarm notification device (not shown) or the like via an antenna 38 by a predetermined radio signal. The notification unit 36 sounds an alarm sound to threaten the intruder. The control unit 37 includes a microcomputer that controls the above-described units, and peripheral circuits such as a memory and a clock.

  FIG. 3 is a block diagram showing a schematic configuration of a magnet sensor transmitter as a first detection device constituting the security system of FIG.

  As shown in FIG. 3, the magnet sensor transmitter 10 includes a magnet switch unit (SW) 11, a magnet I / F unit 13, a transmission unit 14, an antenna 15, and a housing 12. A control unit 16 and a battery 17 are included.

  The magnet switch unit 11 is disposed in the vicinity of the window 60 and the door 70, and outputs a detection signal to the control unit 16 when it detects the opening of the window 60 or the door 70. The magnet I / F unit 13 is an interface circuit that performs communication with the magnet switch unit 11, receives a detection signal from the magnet switch unit 11, and outputs the detection signal to the control unit 16.

  The transmission unit 14 converts the detection signal into a wireless signal and wirelessly transmits the signal from the antenna 15 to the controller 30. The control unit 16 includes a microcomputer and peripheral circuits such as a memory and a clock, and controls the above-described units. The battery 17 supplies power to them.

  FIG. 4 is a block diagram showing a schematic configuration of a human sensor transmitter as a second detection device constituting the security system of FIG.

  As shown in FIG. 4, the human sensor transmitter 20 includes a human sensor unit 22, a transmission unit 23, an antenna 24, a notification sound generation unit 25, and a control unit that are provided inside the housing 21. 26 and a battery 27.

  The human sensor unit 22 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 26 when the presence of a person is detected. The human sensor unit 22 is not fixed to the housing 21 and the direction of the human sensor unit 22 can be changed. Even if the human sensor 22 is not physically driven, a structure in which the direction and depth of the detection area can be changed with a lens may be used. Moreover, the blind spot of the sensor detection by the human sensor part 22 can also be reduced by enlarging a detection area using two or more sensor parts. The transmission unit 23 converts the detection signal into a wireless signal and wirelessly transmits the signal from the antenna 24 to the controller 30. While the human sensor 22 detects the approach of a person, a signal indicating the approach of a person is transmitted to the controller 30 at a predetermined time T1 as the first time.

  When the person moves away and the human sensor unit 22 no longer detects the person, the non-detection signal is converted into a radio signal and wirelessly transmitted from the antenna 24 to the controller 30. The notification sound generating unit 25 as a notification unit is configured with a buzzer, for example, and notifies the user with a buzzer (small volume) when there is a detection signal. 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 human sensor 22 is not limited to a passive infrared sensor, but generates an ultrasonic wave, measures the time until the ultrasonic wave is reflected and returns, and measures the distance to the person. An ultrasonic sensor may be used. If an ultrasonic sensor is used, it is possible to eliminate erroneous detection that a person is approaching due to a temperature change caused by direct sunlight, which is a drawback of a passive infrared sensor.

  Further, as the human sensor unit 22, a reflection type optical sensor that generates light such as infrared rays, measures whether the light is reflected and returns, and detects the presence or absence of an approaching person may be used. Good.

  Furthermore, as the human sensor unit 22, light such as infrared rays is generated, the light is received by a separately installed light receiving unit, and the presence of a person approaching is detected by detecting that an approaching person blocks the light. A transmissive infrared sensor may be used.

  Furthermore, by using an image recognition sensor that detects the presence or absence of an approaching person by performing image recognition processing on the camera image as the human sensor unit 22, it is possible to accurately detect the approach of a person from outside the building. Can do.

  Next, the operation | movement according to the operation mode of the security system 1 is demonstrated. When the controller 30 is set to the security release state in the operation unit 31, even if the controller 30 receives a signal that the magnet sensor transmitter 10 detects opening / closing of the door 70 or the like, the alarm and notification operation Do not do. Further, when the presence sensor transmitter 20 detects the presence of a person approaching the building from the outside of the building, it emits a small notification sound to notify that the security system is installed, and transmits the detected signal to the controller 30. . Even if the controller 30 receives the signal, it does not perform an alarm or notification operation.

  If the controller 30 receives the signal that the magnet sensor transmitter 10 detects the opening and closing of the door 70 and the like when the operation unit 31 of the controller 30 is set to the security setting state, the notification unit 36 In order to intimidate, an alarm sound is sounded, and the reporting unit 33 reports an abnormality to the security center 40 via the communication line 50. Further, when the presence sensor transmitter 20 detects the presence of a person approaching the building from the outside of the building, it emits a small notification sound to notify that the security system is installed, and transmits the detected signal to the controller 30. .

  Even if the controller 30 receives the signal, the controller 30 does not immediately perform an alarm or notification operation. When receiving the human approach signal from the human sensor transmitter 20, the controller 30 determines whether or not to receive the human approach signal again within the set time T2. The set time T2 of the controller 30 as the second time is set to be longer than the time interval T1 at which the human sensor transmitter 20 repeatedly transmits the human approach while detecting the approach (T2> T1). In addition, when a no-detection signal is received from the human sensor transmitter 20, the reception waiting for the detection signal (T2 time count) is cleared.

  While the human sensor unit 22 detects the approach of a person, a signal indicating the approach of a person is transmitted to the controller 30 every predetermined time T1. When a person moves away and the human sensor unit 22 no longer detects, the no-detection signal is converted into a radio signal and wirelessly transmitted from the antenna 24 to the controller 30.

  If the security system 1 is normal, the human sensor transmitter 20 transmits a human detection presence signal at predetermined time intervals T1 while detecting the approach of a human, so that the controller 30 is within the set time T2. Can be received.

  If the controller 30 does not receive a human detection signal or no detection signal from the human sensor transmitter 20 even after the set time T2 has elapsed after receiving the human detection signal of the human sensor transmitter 20, When the human sensor transmitter 20 is broken or it is determined that the system is broken, the notification unit 36 sounds an alarm sound to threaten the intruder, and the notification unit 33 transmits the security center 40 via the communication line 50. An abnormal report is sent to. In this case, if the intrusion detection device number that detected the abnormality and the information that can identify the abnormality type such that the retransmission of the detection signal cannot be received, the security center 40 can make an appropriate determination.

  In this way, the human sensor transmitter 20 informs that the security system is installed with a small notification sound only when the presence of a person approaching the building is detected. This alarm sound is a sound that is not of concern to the residents, but makes it difficult for people who want to invade, such as burial nests, to recognize that it is a building that is difficult to invade. And not.

  This makes it possible to discourage intrusion, and a function to prevent intrusion can be obtained as a security system. When the human sensor transmitter 20 installed outside the building is broken because a suspicious person enters the building, the controller 30 determines that no signal is received. In the same manner as when an intrusion is detected in the building, threatening by a loud alarm sound and reporting an abnormality to the security center 40 can be performed.

  FIG. 5 is a block diagram showing a schematic configuration of another embodiment of a human sensor transmitter as a second detection device constituting the security system of FIG.

  As shown in FIG. 5, the human sensor transmitter 20 includes a human sensor unit 22, a transmission unit 23, an antenna 24, a display unit 28, and a control unit 26 that are provided inside the housing 21. And a battery 27.

  The human sensor unit 22 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 26 when the presence of a person is detected. The transmission unit 23 converts the detection signal into a wireless signal and wirelessly transmits the signal from the antenna 24 to the controller 30. Note that while the human sensor unit 22 detects the approach of a person, a signal indicating the approach of a person is transmitted to the controller 30 every predetermined time T1. When a person moves away and the human sensor unit 22 no longer detects, the non-detection signal is converted into a radio signal, and is wirelessly transmitted from the antenna 24 to the controller 30. The display unit 28 as a notification unit is configured by an LED, and when there is a detection signal, the LED blinks to notify that the security system is installed. 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.

  Thus, there is an effect of giving up intrusion by actively notifying the installation of the security system using the display unit instead of the notification sound. In addition, the LED of the display unit 28 is not always blinked, but is blinked only when the approach of a person is detected, so that power consumption can be reduced, especially when the detection device is driven by a battery. Is possible, and usability is improved.

  FIG. 6 is a block diagram showing a schematic configuration of still another embodiment of a human sensor transmitter as a second detection device constituting the security system of FIG.

  As shown in FIG. 6, the human sensor transmitter 20 includes a human sensor unit 22, a transmitter 23, a receiver 29, an antenna 24, and a notification sound generator provided inside the housing 21. (Small) 25a, notification sound generating unit (large) 25b, control unit 26, and battery 27 are included.

  The human sensor unit 22 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 26 when the presence of a person is detected. The transmission unit 23 converts the detection signal into a wireless signal and wirelessly transmits the signal from the antenna 24 to the controller 30. Note that while the human sensor unit 22 detects the approach of a person, a signal indicating the approach of a person is transmitted to the controller 30 every predetermined time T1. When a person moves away and the human sensor unit 22 no longer detects, the non-detection signal is converted into a radio signal, and is wirelessly transmitted from the antenna 24 to the controller 30.

  The notification sound generating unit (small) 25a is configured with a small volume buzzer, and when there is a detection signal, the buzzer (small volume) is notified. The notification sound generator (large) 25b is composed of a loud buzzer. When the alarm signal from the controller 30 is received by the receiving unit 29 via the antenna 24, the alarm sound is emitted by the loud buzzer. Intimidate. 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.

  As described above, when an intruder is detected in the alert area, the controller 30 sounds an alarm sound and also transmits an alarm start signal as a radio signal in order to threaten the intruder by the notification unit 36. When the alarm start signal is received by the receiving unit 29 of 20, the alarm sound is sounded with a high-volume buzzer and threatens, so that not only the controller 30 but also the human sensor transmitter 20 installed outside the building Because it can be intimidated by sounding an alarm sound, it is more effective to repel intruders.

  Although the above embodiment has been described with the configuration using the high volume buzzer and the low volume buzzer, the volume for notification and threatening is changed by changing the voltage or sound data from the control unit 26 in one buzzer. You may adopt the method of changing.

  FIG. 7 is a block diagram showing a schematic configuration of a magnet sensor transmitter in which the first detection device and the second detection device are integrated in the security system as another embodiment of the intrusion warning system of the present invention. .

  The magnet switch unit 11 is disposed in the vicinity of the window 60 and the door 70, and outputs a detection signal to the control unit 16 when it detects the opening of the window 60 or the door 70. The magnet I / F unit 13 is an interface circuit that performs communication with the magnet switch unit 11, receives a detection signal from the magnet switch unit 11, and outputs the detection signal to the control unit 16. The transmission unit 14 converts the detection signal into a wireless signal and wirelessly transmits the signal from the antenna 15 to the controller 30. The human sensor unit 18 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 16 when the presence of a person is detected.

  The transmission unit 14 converts the detection signal into a wireless signal and wirelessly transmits the signal from the antenna 15 to the controller 30. Note that while the human sensor unit 18 detects the approach of a person, a signal indicating the approach of a person is transmitted to the controller 30 every predetermined time T1. When the person moves away and the human sensor unit 18 no longer detects, the non-detection signal is converted into a radio signal and transmitted wirelessly from the antenna 15 to the controller 30.

  The notification sound generation unit 19 is configured with a buzzer, and notifies the user with a buzzer (small volume) when there is a detection signal from the human sensor unit 18. The control unit 16 includes a microcomputer and peripheral circuits such as a memory and a clock, and controls the above-described units. The battery 17 supplies power to them.

  Thus, the human sensor unit 18 for detecting a person approaching from the outside of the alerted building and the security system are installed in the magnet sensor transmitter 10 for detecting the intrusion into the alert area in the building. By installing the notification sound generator 19 for notifying that, that is, by integrating the first and second detection devices, the number of required detection devices can be reduced, and entry is cheap. Can be provided.

  8 is a perspective view (A) and a cross-sectional view (B) showing an installation example of the magnet sensor transmitter of FIG.

  As shown in FIG. 8, the housing 12 of the magnet sensor transmitter is fixed to the indoor window frame portion 61, and the magnet switch portion 11 (magnet side) is fixed to the indoor side of the outer window glass 62.
