It is an operation | movement flowchart of the arson suppression system which concerns on this invention. It is an operation | movement flowchart in the alert mode of the arson suppression system which concerns on this invention.

  Based on FIG. 1 thru | or FIG. 5, the arson suppression system which concerns on this invention is demonstrated.

  First, the sensor installation mode will be described with reference to FIG. Reference numeral 1 denotes a building to be protected (for example, a building such as a shrine or a mountain gate), 10 denotes a human body sensor, and 20 denotes a flame sensor. When the building 1 to be protected is an important cultural property, the flame sensor 20 or the like cannot be attached to the eaves of the building 1 or the like. This is because the building 1 may be damaged by the attachment.

  Therefore, the flame sensor 20 is attached to the tree 3 adjacent to the building 1. The tree 3 may be an artificial object such as a steel pillar instead of the tree 3 if allowed by the landscape. The human body sensor 10 is installed outside the building 5 adjacent to the building 1. If this is also permitted in the landscape, an artificial object such as a steel pillar instead of the building 5 may be used. At this time, the human body sensor 10 and the flame sensor 20 are attached so that the building 1 to be protected and its surroundings are within the field of view. If one unit cannot monitor the building 1 and its surroundings, a plurality of sensors 10 and 20 are installed using a tree 3 or a building 5 (not shown) adjacent to the building 1. In this way, by installing one or a plurality of sensors 10 and 20 around the building 1, it is possible to detect the type of fire ignited by the person trying to approach and set off the person in the building 1 and its surroundings. It is.

  Here, the sensors 10 and 20 may perform power supply and signal transmission / reception by wire if the electric wires can be installed in consideration of the landscape, but are installed outdoors away from the building 1 Therefore, in consideration of installation outdoors, a sensor that can supply power by a solar cell and transmit an abnormal signal wirelessly is desired.

  The block configuration of such sensors 10 and 20 will be described below with reference to FIG. In FIG. 1, 10 is a human body sensor, 20 is a flame sensor, 30 is a receiver, and 40 is a fire extinguishing device.

Although the human body sensor 10 has been described as not provided in the flame sensor 20, the human body sensor 10 may be provided in the flame sensor 20 and integrated. For convenience of explanation, the following description will be made assuming that the human body sensor 10 is not included in the flame sensor 20.
First, the block configuration of the human body sensor 10 will be described. The human body sensor 10 has a human body detection unit 11. The human body detection unit 11 is a known means for detecting the presence of a human using a laser beam, ultrasonic waves, infrared rays, radio waves, or the like. Reference numeral 12 denotes a wireless transmission unit that wirelessly transmits an intrusion signal to the wireless transmission / reception unit 25 of the flame sensor 20 when the human body detection unit 11 detects a human body. 13 is a solar cell that converts sunlight into electrical energy, and the generated electricity is stored in a power supply unit 14 having a rechargeable battery and is transferred to another block such as the human body detection unit 11 via the control unit 15. Supplied. While the solar cell 13 generates electricity only during the daytime, arson is often performed mainly at night when there is no human being, so the capacity of the rechargeable battery has a capacity sufficient for nighttime monitoring. In addition, when a necessary power generation amount can be obtained depending on the installation location, other power generation means such as wind power generation may be used.

  Next, the configuration of the flame sensor 20 will be described. Reference numeral 23 denotes a solar battery, which is the same as the solar battery 13 provided in the human body sensor 10. Reference numeral 24 denotes a power supply unit, which is also the same as the power supply unit 24 provided in the human body sensor 10. The rechargeable battery provided in the power supply unit 24 is monitored by the flame sensor 20 throughout the day and night, and has sufficient capacity to operate a lighting unit, a camera unit, a sound output unit, and the like, which will be described later, for a predetermined time at night.

  Reference numeral 2A denotes a 24-hour timer, which is a time measuring means, or an illuminance detection unit, which is an illuminance detection means, as day / night discrimination means. When using a 24-hour timer for the day / night discriminating means 2A, the day / night range is set to determine day and night, and when using the illuminance detecting means, it is discriminated that daytime is greater than or equal to a predetermined illuminance and nighttime is less than a predetermined illuminance. . The time setting in the day / night range of the 24-hour timer may be set in consideration of seasonal variations using software. When the illuminance detection unit is used as the day / night discrimination means 2A, depending on the weather such as cloudy or rain, or the installation location such as the shade, it may be discriminated as nighttime due to a decrease in illuminance even during the day. This is also advantageous when arson is expected. These are appropriately selected according to the management system according to the protection target.

  Although the day / night discrimination means 2A is described as being provided in the flame sensor 20, the day / night discrimination means 2A is provided in the human body sensor 10 so that only the intrusion signal at night is transmitted from the wireless transmission unit 12 to the flame sensor 20. May be. Alternatively, a signal that discriminates day and night may be transmitted to the flame sensor 20 by a wireless device in a place different from the human body sensor 10 and the flame sensor 20. For convenience of explanation, the following description will be made assuming that the flame sensor 20 includes the day / night discrimination means 2A.

Reference numeral 21 denotes a flame detection unit for detecting a flame. For example, an infrared detection element for detecting a wavelength in the 4.3 μm band by CO ₂ resonance radiation peculiar to the flame, a wavelength in the 4.3 μm band, and a plurality of wavelengths before and after the wavelength. Either an infrared detecting element for detecting that the peak of the wavelength distribution exists in the 4.3 μm band peculiar to the flame, a detecting element such as an ultraviolet detector, or any other element for detecting flame peculiar to the flame, or And a flame detection device in which a plurality of detection elements are combined.

  Reference numeral 22 denotes a sensitivity setting unit that sets the sensitivity of the flame detection unit 21 and can be switched to, for example, two stages of high sensitivity and low sensitivity. Alternatively, 22 may be a response time setting unit for setting the response time of the flame detection unit, and for example, switching between two stages of “long time” for performing a delay operation for a predetermined time and “short time” for fast movement. Anyway.

  The sensitivity setting unit or response time setting unit 22 is highly sensitive if it is a sensitivity setting unit, and only a short time (fast motion if it is a response time setting unit) when an intrusion signal is received at night determined by the day / night discrimination means 2A. ) To prevent the flame detector 21 from malfunctioning due to transient disturbance light or the like. For convenience of explanation, 22 will be described as a sensitivity setting unit hereinafter.

  Reference numeral 25 denotes a wireless transmission / reception unit that serves as both a wireless reception unit that receives an intrusion signal from the human body sensor 10 and a wireless transmission unit that transmits an arson signal to the receiver 30. The wireless transmission / reception unit 25 may be separated into the wireless transmission unit and the wireless reception unit.

  When the wireless transmission / reception unit 25 wirelessly receives an intrusion signal from the human body sensor 10 at night, the flame sensor 20 shifts to a warning mode. The flame sensor 20 that has shifted to the alert mode controls the sensitivity setting unit 22 to be set to high sensitivity, and controls the illumination unit 28, the camera unit 27, and the audio output unit 26 as an acoustic output unit as will be described later. To do. Note that, depending on the security system, the flame sensor 20 may be set in a security mode when an intrusion signal from the human body sensor 10 is received wirelessly, regardless of day or night, and is appropriately selected depending on the security system of the facility.

  When the flame sensor 20 is in the alert mode, when the flame detection unit 21 further detects a flame, the flame sensor 20 shifts to the threat mode. The flame sensor 20 that has shifted to the threatening mode wirelessly transmits an arson signal to the receiver 30, and controls the illumination unit 28, the camera unit 27, and the audio output unit 26 as an acoustic output unit as will be described later.

  A plurality of warning levels are provided in stages according to the duration of the warning mode, and the lighting unit 28, the voice output unit 26, etc. are controlled so as to be alert in a non-intimidating range for each warning level. May be.

  When the flame sensor 20 is not in the alert mode, the flame sensor 20 shifts to the fire mode when the flame detector 21 detects the flame. The flame sensor 20 that has shifted to the fire mode wirelessly transmits a fire signal to the receiver 30.

  An audio output unit 26 as an audio output unit may be a sound device such as a buzzer. Here, the audio output unit functions more effectively for notification, warning, and threatening. The voice output unit 26 has a plurality of voice messages registered in advance, and outputs a designated voice message in response to a command from the control unit 29. For the registration of the voice message, voice data prepared in advance may be registered in a storage unit (not shown) in the voice output unit 26, or a real voice may be recorded in the storage unit as voice data.

  When the flame sensor 20 shifts to the warning mode, the voice output unit 26 outputs a calm voice message that does not intimidate, such as the start of monitoring, such as “Start monitoring for security”. To control.

  Note that the voice output unit 26 may be controlled by the control unit 29 so as to output voice messages stepwise so as to be alert in a range not threatened according to the alert level. For example, nothing is output at the first level immediately after the human body sensor 10 outputs the intrusion signal, and at the second level after a predetermined time has passed, “monitoring will start for security” is notified that monitoring has started. In the third level after a predetermined time has passed, “You are already in the same place for another minute. If you keep this, you will be recorded as a suspicious person. Output a voice message that warns as much as possible, and at the fourth level after a predetermined time has passed, output a voice message that has already been captured as a suspicious person, saying "Warning, warning, record as suspicious person and start recording" . At this time, the flame sensor 20 may wirelessly transmit a suspicious person signal to the receiver 30.

  When the flame sensor 20 shifts to the intimidating mode, an intimidating and intimidating voice message is output, such as “discover the fire! Discover the fire! Record the arson suspect and issue a fire alarm!”.

  In addition, although the audio | voice output part 26 demonstrated as what is equipped with the flame sensor 20, you may make it operate | move by receiving the control signal from the flame sensor 20 or the receiver 30 by radio | wireless in other places. .

  Reference numeral 28 denotes an illumination unit, which is controlled by the control unit 29 so that the illumination unit 28 is turned on when the wireless transmission / reception unit 25 receives an intrusion signal and shifts to the alert mode.

  The illumination unit 28 is controlled by the control unit 29 so as to change the illumination stepwise so as to exert a synergistic effect with the audio output unit 26 so as to be alert in a range not threatened according to the alert level. Also good. For example, at the warning level 1, the lighting unit 28 is simply turned on, and at the warning level 2, the state of the warning level 1 is maintained, or the illumination color of the lighting unit 28 is changed to a cold color system, and at the warning level 3, the lighting unit 28 is maintained. The warning color is changed to a warning color such as yellow or red, and at a warning level 4, a plurality of lighting colors including the warning color are alternately turned on at a predetermined long cycle (for example, a cycle longer than the blinking cycle of a traffic signal). As described above, it is more effective to control the voice output unit 26 and the illumination unit 28 so as to produce an effect of encouraging the alert whenever the alert level increases. In the example shown at the warning level 1, since it is the same operation as a sensor light that is generally spread, it does not threaten a mere passerby or a bona fide visitor who does not intend to fire.

  When the flame sensor 20 shifts to the threatening mode, the illumination unit 28 is controlled by the control unit 29 to threaten. For example, a plurality of illumination colors including a warning color are alternately turned on at a predetermined short cycle (for example, a cycle shorter than a blinking cycle of a traffic signal). Since the illumination unit 28 is also an imaging illumination for the camera unit 27, it is desirable to control the illumination unit 28 so that there is no extinguishing period. However, when the illumination unit 28 is blinked in order to increase the threatening effect, the illumination unit 28 is used for imaging. A near infrared light source that cannot be felt by a person may be used in combination as the light source.

  Although the illumination unit 28 has been described as being provided in the flame sensor 20, the illumination unit 28 may be provided in another location and operated by receiving a control signal from the flame sensor 20 or the receiver 30 wirelessly.

  Reference numeral 27 denotes a camera unit including a monitoring camera, and the imaging range thereof is installed so as to include the monitoring range of the flame detection unit 21. When the flame sensor 20 shifts to the alert mode, the camera unit 27 is activated by the control unit 29 and is controlled so that the illumination light of the illumination unit 28 that is turned on simultaneously illuminates the imaging range. The image signal captured by the camera unit 27 is transmitted to the receiver 30 wirelessly.

  In the alert mode, depending on the alert level, the camera unit 27 controls a dummy recording lamp (not shown) provided in the camera unit 27 to light up so that an approaching person can recognize it without actually capturing an image. May be. For example, the camera unit 27 may not be activated until the alert level 4 is reached. Further, at the warning levels 1 to 3 up to the warning level 4, the dummy recording lamp may be turned on. When the flame sensor 20 reaches the warning level 4, an image signal captured by the camera unit 27 may be transmitted to the receiver 30 together with a suspicious person signal.

  When the flame sensor 20 shifts to the threatening mode, the image signal captured by the camera unit 27 is wirelessly transmitted to the receiver 30 together with the fire signal.

  Although the camera unit 27 has been described as being provided in the flame sensor 20, the camera unit 27 may be provided in another location and operate by receiving a control signal from the flame sensor 20 or the receiver 30 wirelessly.

  Thus, in the flame sensor 20, each of the blocks 21 to 28 and 2A is controlled by the control unit 29, and the control unit 29 is in a warning mode when the wireless transmission / reception unit 25 receives an intrusion signal from the human body sensor 10, Moreover, when the flame detection part 21 detects a flame, it will become threatening mode.

  In addition, although the power supply of each sensor was obtained from the solar cells 13 and 23, you may make it supply a power supply via an electric wire, and may drive with a dry cell etc. Note that the monitoring visual field of the human body sensor 10 may be provided outside the monitoring visual field of the flame sensor 20. If it does in this way, even if a fire kind is thrown in from the place where the fire prevention object is distant, since the monitoring visual field of the human body detection sensor 10 is large, it is possible to detect the arson. Thus, in the arson control system of the present invention, the sensors 10 and 20 are supplied with power by the solar cells 13 and 23 and the power supply units 14 and 24, and transmit an abnormal signal such as an arson signal by the wireless transmission unit 12. This eliminates the need for power supply and signal transmission wires. For this reason, a system can be constructed when a sensor cannot be installed directly on an object to be protected, such as an important cultural property.

  Next, the configuration of the receiver 30 will be described. The receiver 30 is always installed in a place where people are present, such as the building 5 near the building 1 to be protected.

  The receiver 30 includes a wireless reception unit 31 that receives an intrusion signal from the human body sensor 10 and the suspicious person signal, the fire signal, the fire signal, and the like from the flame sensor 20, and receives the suspicious person signal. "Intrusion of suspicious person", "Fire" when receiving an arson signal, "Fire" when receiving a fire signal, alarm action, transfer action, interlock action, etc. according to each I do. In addition to receiving the arson signal, it may be determined that arson has been received when both the intrusion signal and the arson signal are received.

  Reference numeral 32 denotes a transfer section, which transfers information to a predetermined portable terminal or the like when the receiver 30 determines any one of suspicious person intrusion, arson, and fire. In the transfer section 32, a report destination of means that can be immediately reported electronically, such as a telephone number or an e-mail address of a mobile phone possessed by the manager of the building 1, is registered. Depending on the security system of the facility, it may be reported to the contracted security company. At this time, the image signal transmitted from the camera unit 27 may be transmitted from the transfer unit 32, or may be recorded in a recording device (not shown) and used as a later investigation material.

  Reference numeral 33 denotes a control unit that controls the wireless reception unit 31, the transfer unit 32, and the building lighting control unit 34, and may further control the fire extinguishing device 40 and a water spray device (not shown). Reference numeral 34 denotes a building lighting control unit which controls to turn on a lighting device (not shown) inside or outside the building close to the arson, such as the building 1 or the building 5, when it is determined that the arson is arson.

  The water spray device is accompanied by a squirt sound when discharging water particles, and is operated when it is determined that the fire is set to fire. It is an attempt to drive away from anxiety with anxiety, and although it has ignited the fire type, it can be expected that the ignition to the building 1 will be discouraged and no arson will occur. If the water spraying device is a device that lowers the ambient temperature by vaporizing fine water particles, that is, a “dry mist (registered trademark)” that is a water spraying device for cooling, or a similar device, the above In addition to this effect, it can also be expected to have an effect on malicious intruders who want to ignite anxiety similar to chills due to a decrease in temperature. The water spraying device that discharges the fine water particles has an effect that it can be used for the purpose of suppressing arson in addition to the original purpose of cooling the surroundings.

  Then, the structure of the fire extinguishing apparatus 40 is demonstrated based on FIG. 1 and FIG.

  The laser 41 is a repetitive oscillation type high-power pulse laser known as a fire extinguishing means, and blows off the flame from directly below with a blast wave (blast) generated by irradiating directly under the flame.

  The fire extinguisher 40 includes the laser 41, an infrared camera 42 serving as an infrared imaging unit, an electric camera platform 43 serving as an angle control unit on which the laser 41 and the infrared camera 42 are fixed and mounted in the same direction. It is comprised from the fire extinguisher control panel 45 to control. When the receiver 30 determines that the fire is set off and the fire extinguisher control panel 45 receives a command from the receiver 30, as shown in FIG. The direction of the flame base is calculated from the captured infrared image by an image processing device (not shown) in the fire extinguishing system control panel, and the motor 41 is controlled to control the laser 41 in the flame base direction. The fire extinguisher control panel 45 controls so that the laser 41 emits laser beam light toward the base of the flame. In addition, the fire extinguishing apparatus 40 may depend on the conventional fire extinguishing method which discharges water toward a fire source from a movable nozzle.

  Next, the case where arson is going to be performed in this system is demonstrated based on FIG. 1 and FIG. The two types of sensors 10 and 20 are supplied with power by electricity generated by the solar cells 13 and 23 during the day, and are supplied by rechargeable batteries of the power supply units 14 and 24 at night.

  First, when a malicious intruder attempting to ignite the building 1 at night approaches, the human body detection unit 11 of the human body sensor 10 detects the intruder (step S5), and the wireless transmission unit 12 wirelessly transmits the intrusion signal. To the flame sensor 20. When the wireless transmission / reception unit 25 of the flame sensor 20 receives the intrusion signal, the sensitivity setting unit 22 performs control so that the sensitivity of the flame detection unit 21 is switched to high sensitivity (step S7). When there is no signal, the monitor mode is shifted from the normal mode to the alert mode (step S11). By setting the flame detection unit 21 to be highly sensitive, the flame detection unit 21 can quickly detect a fire-type flame that is ignited by the arson in order to ignite the building 1.

  When a plurality of flame sensors 20 are installed, all the flame detectors 21 of the flame sensor 20 provided in the vicinity of the activated human body sensor 10 and receiving the intrusion signal are switched to high sensitivity.

  Further, when the flame sensor 20 shifts to the alert mode, the camera unit 27 is activated and the illumination unit 28 is controlled to be turned on. As the camera unit 27 is activated, the range monitored by the flame detection unit 21 is imaged. Since the arson is normally performed in an invisible time such as at night, the illumination unit 28 is turned on to brighten the imaging range of the camera unit 27 and its surroundings, or the periphery of the building 1, so that the normal monitoring range is obtained. Can be imaged. The captured image may be transmitted to the receiver 30 and recorded on a security recording device (not shown), or may be transmitted to a predetermined portable terminal or the like via the receiver 30.

  In addition, at the stage of transition to the warning mode, the person detected as an intruder may not be a arson, but may be a bona fide visitor such as a visit to a shrine or a pedestrian who uses the site as a shortcut. It is not necessary to use the image that has been used. In addition, the camera unit 27 is not activated and is not actually picked up, and a dummy recording light (not shown) provided on the camera unit 27 is turned on to monitor a malicious intruder attempting to set fire. You just need to recognize. For the same reason, it is desirable to control the voice output unit 26 to send a non-intimidating voice message indicating the start of monitoring after a predetermined time has passed since the transition to the warning mode.

  In addition, as shown in FIG. 5, according to the duration of the alert mode, a plurality of alert levels are provided in stages, and the illumination unit 28, the audio output unit 26, etc. are alerted within a range not intimidating for each alert level. It may be controlled so as to scold.

  For example, at the first level immediately after the human body sensor 10 outputs the intrusion signal, the illumination unit 28 is turned on and the audio output unit 26 does not output anything. At this stage, the operation is similar to that of a sensor light that is widely used, so that it does not intimidate mere passers-by or well-intentioned visitors who are not willing to fire. Furthermore, at the second level after a predetermined time has passed, the lighting unit 28 is kept lit in the same manner as the first level, or the lighting color is changed to a cold color system. ”Will output a voice message notifying that monitoring has started. Furthermore, at the third level after a predetermined time has passed, the illumination color of the illumination unit 28 is changed to a warning color such as yellow or red, and the voice output unit 26 “is already in the same place. Record as a suspicious person as it is. "Please move quickly." A warning message is issued to warn you to leave. Further, at a fourth level after a predetermined time has elapsed, the lighting unit 28 alternately turns on a plurality of lighting colors including a warning color at a predetermined long cycle (for example, a cycle longer than the blinking cycle of a traffic signal). “Warning, warning, recording as suspicious person and start recording” is output as a voice message already captured as a suspicious person. At this time, the flame sensor 20 may wirelessly transmit a suspicious person signal to the receiver 30. In this way, it is effective to control the sound output unit 26 and the lighting unit 28 so as to produce an effect that makes a warning every time the alert level rises, and the range up to a warning stage that does not lead to intimidation. If it stops, operation other than the above-mentioned illustration may be sufficient.

  In addition, in order to introduce such a device, it is necessary to indicate that “a device for protecting important cultural properties and other structures from arson” has been introduced in the passage leading to the monitoring range. desirable. By reading this display to the bona fide visitor, it is possible to prevent the user from being surprised by an operation such as the start of unintentional monitoring, and to make it known that efforts are being made to prevent arson. In addition, for those who intend to set fire, an indication that the “device for protecting from fire” has been introduced is a warning, and an effect of losing the will of fire can be expected simply by reading the display.

  When a malicious intruder who wants to set fire next ignites a fire type to set fire, the flame detection unit 21 detects the flame, the flame sensor 20 shifts to a threatening mode, and the lighting unit 28 is threatened. The voice output unit 26 is controlled to output a threatening voice message to threaten the arson, and the camera unit 27 is activated, and the wireless transmission / reception unit 25 transmits the arson signal to the receiver 30. The wireless transmission / reception unit 25 also transmits an image captured by the camera unit 27 to the receiver 30.

  When receiving the arson signal from the flame sensor 20, the wireless receiver 31 of the receiver 30 determines that the arson has been ignited and activates an alarm unit (not shown) to warn that the arson action has been performed. In addition, an image captured by the camera unit 27 is displayed on a display unit (not shown). Thereby, while being able to grasp | ascertain the condition of the building 1, the crime scene of the arson act by the arson can be confirmed. In addition, you may make it record the image which the camera part 27 imaged on the recording apparatus for crime prevention which is not shown in figure.

  When the receiver 30 determines that the fire is set to fire, the transfer unit 32 transfers the fire signal to the manager's mobile terminal or the like. As a result, the manager can know that the arson act has been performed on the building 1 without being away from the building 5 and near the receiver 30.

  The fire signal may be transferred not only to the administrator but also to the fire department or police station. In this case, information that can specify the position of the building 1 is sent together with the arson signal.

  Furthermore, when the threatening mode has elapsed for a predetermined time, the receiver 30 shifts to the fire-stopping mode so as to stop the fire and activates the fire extinguishing device 40 before the person trying to fire the building 1 to be protected ignites. In addition, the ignited fire type may be extinguished at the stage of the fire type so as not to be lit.

  When the fire extinguisher control panel 45 receives a fire extinguishing command from the receiver 30 determined to be lit, the infrared camera 42 on the electric pan head 43 that performs the turning operation searches for the position of the flame F, and the captured infrared image is extinguished. Image processing is performed by an image processing device (not shown) in the control panel, the direction of the base of the flame F is calculated, the electric head 43 is controlled to direct the laser 41 in the direction of the base of the flame F, and the flame The fire extinguisher control panel 45 controls the laser beam to be emitted from the laser 41 toward the base of F. Since the flame F is extinguished by the fire extinguishing device 40 when the fire type is ignited to ignite, the building 1 to be protected is not ignited. In addition, the fire extinguishing apparatus 40 may depend on the conventional fire extinguishing method which discharges water toward a fire source from a movable nozzle.

  As described above, the arson deterrent system according to the present invention detects an intruder by the human body sensor 10 and enters a warning mode. In addition, the fire sensor 20 detects the type of fire ignited by the flame sensor 20 and enters a threatening mode. The threatening firefighter is threatened to ignite the building 1 to be protected. The fire is set to the arson prevention mode after a certain period of time, and the ignited fire type is extinguished at the fire type stage to prevent ignition of the building 1 to be protected. Arson can be deterred.
