[Description of Embodiment of the Present Invention]
First, the contents of the embodiment of the present invention will be listed and described.
(1) The present invention executes a fire detection processing unit for performing a fire detection process for performing a fire detection based on an image captured by the monitoring camera, and a non-fire monitoring process for performing monitoring by the monitoring camera without performing a fire detection A non-fire monitoring processing unit, and a switching processing unit that executes a switching process for switching the mode of the monitoring process from the first monitoring mode to the second monitoring mode based on information received from outside the processing device, The first monitoring mode is a mode for performing at least the non-fire monitoring process, and the second monitoring mode is a processing apparatus for performing at least the fire detection process.
The non-fire monitoring process is a normal monitoring process such as image storage, human detection (detection of detection target), and camera control for tracking a suspicious person.

  In the present invention, the processing device can perform normal monitoring by the monitoring camera without performing fire detection by the non-fire monitoring processing in the first monitoring mode. Further, the first monitoring mode can be switched to the second monitoring mode by the switching process, and the fire detection based on the captured image of the monitoring camera can be performed by the fire detection process in the second monitoring mode. Therefore, it is possible to monitor an intruder or a suspicious person and detect a fire with the processing apparatus without providing a camera for fire detection separately from the monitoring camera.

  (2) It is preferable that the said switching process part performs the said switching process based on the detection information of the fire detector which detects a fire. In this case, switching processing can be performed based on detection information of a fire detector that detects a fire.

  (3) Conventionally, fire detectors have been set to a high fire detection standard so that an alarm is not issued unless a certain level of fire occurs to prevent false detection. Therefore, in order to detect a fire early, the switching processing unit is based on detection information of the fire detector with a fire detection standard lower than a fire detection standard for the fire detector itself to detect a fire. It is preferable to execute the switching process.

  In this case, if the fire detector itself exceeds a fire detection standard (first detection standard) lower than the fire detection standard (second detection standard) for detecting a fire, the first monitoring mode is switched to the second monitoring mode. Fire detection based on the image. For this reason, compared with the case where it determines with the fire having generate | occur | produced when the 2nd detection standard is exceeded, the early detection of a fire is attained.

  The fire detection standard can be, for example, the threshold value of the detection value of the fire detector or the sensitivity of the fire sensor. When the fire detection standard is a threshold value of the detection value, a large threshold means that the fire detection standard is high. In addition, when the fire detection standard is sensitivity, being insensitive (detected after the fire becomes large) means that the fire detection standard is high.

  (4) When the fire is detected by the fire detection process in the second monitoring mode, the processing device executes a fire situation estimation process for estimating a fire situation based on the image. It is preferable that it is further included. In this case, when a fire is detected, the fire situation can be estimated based on the captured image by the fire situation estimation process.

(5) It is preferable that the said fire condition estimation process includes the process which estimates the advancing direction of a fire. In this case, the fire traveling direction can be predicted by the fire situation estimation process.
(6) It is preferable that the said fire condition estimation process includes the process which estimates the occurrence place of a fire. In this case, the location of the fire can be estimated by the fire situation estimation process.

  (7) It is preferable that the processing device further includes an equipment control processing unit that executes equipment control processing for controlling the fire countermeasure equipment based on a processing result of the fire situation estimation processing. In this case, the fire control equipment can be controlled by the equipment control processing based on the processing result of the fire situation estimation processing. Here, the fire countermeasure equipment includes fire extinguishing equipment, evacuation guidance equipment, smoke exhaust equipment, alarm equipment, fire doors, and the like.

  (8) The predetermined evacuation route at the time of fire occurrence may be inappropriate due to the direction of flame or smoke depending on the location of the fire occurrence. Therefore, it is preferable that the fire countermeasure equipment includes evacuation guidance equipment, and the equipment control processing includes processing for controlling a manner of evacuation guidance in the evacuation guidance equipment based on a processing result of the fire situation estimation processing. . In this case, the way of evacuation guidance in the evacuation guidance facility can be controlled based on the processing result of the fire situation estimation process.

  (9) When a fire is detected, the fire extinguishing equipment must be operated immediately. On the other hand, if the fire extinguishing equipment is operated, it will be submerged and the building will be damaged or the interior parts will not be usable. Therefore, it should be avoided to operate in an unnecessary place other than the place where the flame is generated. Therefore, the fire countermeasure equipment includes a plurality of fire extinguishing equipment, and the equipment control processing is performed by selecting a fire extinguishing equipment to be operated among the plurality of fire extinguishing equipment based on the result of the fire situation estimation processing. It is preferable that the process which operates a fire extinguishing equipment is included. In this case, based on the result of the fire situation estimation process, a fire extinguishing facility to be operated can be selected from the plurality of fire extinguishing facilities, and the selected fire extinguishing facility can be operated.

(10) It is preferable that the switching processing unit executes the switching process when it is time to perform the switching process. In this case, the switching process can be executed at the time to be performed.
(11) The present invention viewed from another viewpoint is a monitoring camera, a processing device that acquires and processes an image captured by the monitoring camera, and
The processing device includes a fire detection processing unit that performs a fire detection process that performs fire detection based on the image, and a non-fire that performs a non-fire monitoring process that performs monitoring by the monitoring camera without performing a fire detection A monitoring processing unit; and a switching processing unit that executes a switching process for switching the mode of the monitoring process from the first monitoring mode to the second monitoring mode. The first monitoring mode includes at least the non-fire monitoring process. The second monitoring mode is a monitoring system in which at least the fire detection process is performed.
ADVANTAGE OF THE INVENTION According to this invention, even if it does not provide the camera for a fire detection separately from a monitoring camera, the monitoring system which can process both an intruder, a suspicious person, etc. and a fire detection can be provided.

[Details of the embodiment of the present invention]
A specific example of the processing apparatus 10 according to the embodiment of the present invention and the monitoring system 1 including the processing apparatus 10 will be described below with reference to the drawings.
〔Monitoring system〕
FIG. 1 is an explanatory diagram of the configuration of the monitoring system 1.
The monitoring system 1 includes a plurality of monitoring cameras 20, a plurality of fire detectors 30 that detect smoke, a processing device 10 that can acquire a captured image of the monitoring camera 20 and execute a monitoring process, and the processing device 10 Fire prevention equipment 35 controlled based on the processing result of the monitoring process.

  The surveillance camera 20 is a camera that captures a visible image normally used for a security camera, and transmits the captured image to the sequential processing device 10. The monitoring camera 20 also includes a self-diagnosis unit 21 that self-diagnose whether or not a failure has occurred and whether or not a fire cannot be detected because the lens is dirty.

  The fire detector 30 includes a sensor 31, a detection unit 32, a storage unit 33, and a communication unit 34. The sensor 31 outputs a fire determination value (detection value). For example, when the fire detector 30 is a photoelectric spot type detector, the fire determination value is an output value of scattered light generated by the light irradiated from the light source (light emitting element) being reflected by smoke particles.

  The detection unit 32 compares the detection value (output value) output from the sensor 31 with a fire determination threshold value, determines the presence or absence of a fire, and outputs the result (detection information). The storage unit 33 stores a fire determination threshold value used for fire determination. The communication unit 34 receives the fire determination threshold value from the processing device 10 and transmits the detection result to the processing device 10. The fire determination threshold value transmitted from the processing device 10 to the communication unit 34 is stored in the storage unit 33, and the detection unit 32 sets the fire determination threshold value to a threshold value used for fire detection.

  The processing device 10 includes a processing unit 11, a storage unit 12, and a communication unit 13. The processing unit 11 performs monitoring processing based on the captured image of the monitoring camera 20, the self-diagnosis result, and the detection result of the fire detector 30. FIG. 2 is an explanatory diagram of the processing unit 11 in the processing apparatus 10. The processing unit 11 includes a fire detection processing unit 11a, a non-fire monitoring processing unit 11b, a switching processing unit 11c, a fire condition estimation processing unit 11d, and an equipment control processing unit 11e. The fire detection processing unit 11a performs a fire detection process for performing a fire detection based on the captured image. The non-fire detection processing unit 11b executes a non-fire monitoring process for recording an intruder or a suspicious person without performing a fire detection. The switching processing unit 11c executes a switching process for switching the first monitoring mode for performing the non-fire monitoring process to the second monitoring mode for performing the fire detection process. When a fire is detected by the fire detection process, the fire situation estimation processing unit 11d executes a fire situation estimation process that estimates a fire situation based on the captured image. The equipment control processing 11e executes equipment control processing for controlling the fire countermeasure equipment 35 based on the processing result of the fire situation estimation processing. The monitoring process includes the above-described fire detection process, non-fire monitoring process, switching process, fire condition estimation process, and facility control process.

  The storage unit 12 stores a program for the processing unit 11 to execute a monitoring process. The communication unit 13 transmits the self-diagnosis instruction information sent from the processing unit 11 to the monitoring camera 20, and transmits the fire determination threshold value sent from the processing unit 11 to the fire detector 30. The communication unit 13 receives the captured image and the self-diagnosis result from the monitoring camera 20, receives the detection result from the fire detector 30, and sends them to the processing unit 11. In addition, the communication unit 13 transmits a control signal to the fire countermeasure equipment 35. Furthermore, the communication unit 13 is connected to the Internet network, and can transmit information on crime prevention and fire to a security company.

  The fire countermeasure equipment 35 includes an alarm device 40, a guide light 50 (evacuation guidance equipment), a sprinkler 60 (fire extinguishing equipment), and a smoke exhausting equipment 70. The guide light 50 is composed of a plurality of lights, and is normally lit all the time. The alarm device 40 emits an alarm sound according to a control signal from the processing device 10. The guide lights 50 are all connected to one drive device 55 (PLC: programmable logic controller). The driving device 55 can individually turn on and off the guide lamps 50 according to a control signal from the processing device 10.

  The sprinkler 60 is also composed of a plurality, and all are connected to one drive device 65. The driving device 65 can individually operate the sprinkler 60 by a control signal from the processing device 10. The smoke exhausting equipment 70 is for discharging smoke to the outside, and is connected to one drive device 75 as in the case of the guide light 50 and the sprinkler 60, and the drive device 75 is controlled by the processing device 10. The smoke exhausting equipment 70 can be individually operated by the signal.

  FIG. 3 is an explanatory diagram showing the relationship between the output value of the sensor, the measurement target amount (the amount of smoke), and the fire determination threshold value. In this embodiment, the fire determination threshold is used as a fire detection criterion, and the ratio (sensitivity coefficient) between the output value of the sensor and the measurement target amount (the amount of smoke) is not changed. The fire determination threshold is the same amount as the output value of the sensor. The detection unit 32 sets the first threshold or a second threshold higher than the first threshold as the fire determination threshold. The second threshold value is a conventional fire determination threshold value that is set high so that an alarm is not issued unless a certain level of fire occurs in order to prevent erroneous detection. The first threshold value is a threshold value for determining whether or not to switch to the second monitoring mode because there is a possibility of fire occurrence, and is an appropriate value that is easy to detect a fire.

  The present invention can be realized not only as such a processing apparatus 10 but also as a processing method performed by the processing apparatus 10. Further, it can be realized as a program for causing a computer to execute such processing, or as a semiconductor integrated circuit constituting part or all of the processing apparatus 10.

  The processing device 10 includes a computer, and each function of the processing device 10 is exhibited by a computer program stored in the storage unit 12 of the computer being executed by the CPU of the computer. The computer program can be stored in a recording medium such as a CD-ROM.

[Fire detection flow]
FIG. 4 is a flowchart of the operation of the fire detection and fire countermeasure equipment 35 by the monitoring system 1. The processing from step S100 to step S135 shown in FIG. 4 is processing performed by the processing device 10. On the other hand, the process of step S140, step S145, step S150, and step S160 shown in FIG. 4 is a process performed by the fire detector 30.
The monitoring camera 20 normally captures an image of a predetermined monitoring range and transmits it to the processing device 10 for recording an intruder or a suspicious person. The processing device 10 normally performs non-fire monitoring processing including at least one of storage processing of a captured image of the monitoring camera 20 and image processing for human detection (detection of a detection target) in the first monitoring mode. (Step S100).

  The detection unit 32 of the fire detector 30 sets the fire determination threshold value to a first threshold value that is lower than the second threshold value. The detection unit 32 of the fire detector 30 receives the detection value output from the sensor 31, and determines whether or not the first threshold value is exceeded (step S105). The processing device 10 continues the normal monitoring mode (first monitoring mode) until the fire detector 30 notifies that the detected value exceeds the first threshold (No in step S105).

  If the processing device 10 receives the detection result that the detected value exceeds the first threshold value from the fire detector 30 (Yes in step S105), is the monitoring camera 20 operating normally according to the instruction from the processing device 10? It is confirmed whether or not (step S110). Specifically, the monitoring camera 20 performs self-diagnosis, such as whether or not a failure has occurred and whether or not a fire cannot be detected because the lens is dirty. This is because if the monitoring camera 20 is not operating normally, the processing device 10 cannot normally detect flames and smoke by image processing in the second monitoring mode, and thus needs to be confirmed in advance. The processing device 10 receives the result of self-diagnosis from the monitoring camera 20 (step S110).

  When monitoring camera 20 diagnoses that it is not operating normally (No in step S110), it transmits the diagnosis result to processing device 10. The processing apparatus 10 that has received the diagnosis result gives up the fire detection by the monitoring camera 20 and transmits a second threshold value to the fire detector 30 as a fire determination threshold value. The detection unit 32 of the fire detector 30 that has received the second threshold changes the fire determination threshold from the first threshold to the second threshold, and performs normal fire detection only by the fire detector 30 (step S140). And the detection part 32 of the fire detector 30 determines whether the detected value exceeded the 2nd threshold value (step S145). The fire detector 30 continues normal fire monitoring by only the fire detector 30 in step S140 until the detected value exceeds the second threshold (No in step S145).

  When the fire detector 30 detects that the detected value exceeds the second threshold value (Yes in step S145), the fire detector 30 informs the manager in the facility of the location of the fire and informs the person in the facility of the occurrence of the fire. A normal fire alarm issuance process is performed (step S150). Further, the fire detector 30 sounds an alarm sound from the alarm device 40 (step S150). Further, the fire detector 30 operates all the sprinklers 60 at the same time in step S150. Furthermore, the fire detector 30 notifies the processing device 10 of the occurrence of the fire, and the processing device 10 that has received the notification notifies the security company of the occurrence of the fire through the Internet in step S150.

  On the other hand, when the monitoring camera 20 diagnoses that it is operating normally (Yes in step S110), the monitoring camera 20 transmits the diagnosis result to the processing device 10. The processing apparatus 10 that has received the diagnosis result switches from the first monitoring mode in which the non-fire monitoring process is performed to the second monitoring mode in which the fire detection process is performed (step S115). In the second monitoring mode, the processing device 10 detects flame and smoke (detects fire) by image processing (step S120).

  Here, flame detection is performed, for example, by creating a difference image of the image captured by the monitoring camera 20 with respect to the most recently captured image as a difference image, and detecting pixels having a predetermined brightness or higher from the average image of the plurality of difference images. Then, when the detected pixel is equal to or greater than a predetermined value, it is determined that it is a flame. For smoke detection, a difference image is created in the same manner as in the case of a flame, and the luminance dispersion of the pixels of the average image of a plurality of difference images is obtained. If the value of the luminance dispersion decreases, it is determined that the smoke is present. Do that. This method uses the fact that when smoke enters the detection area, the field of view becomes blurred, and the range of the luminance distribution is narrower (the value of the luminance dispersion is reduced) than when there is no smoke. It is.

  When the flame and smoke are detected in step S120 (Yes in step S120), the processing device 10 predicts the traveling direction of the flame and smoke from the temporal change in the flame and smoke area calculated from the difference image. Processing is performed (step S125). In addition, the processing device 10 performs a process of estimating the location of the fire from the location of the monitoring camera 20 that has detected the flame or smoke and the position of the flame or smoke in the captured image of the monitoring camera 20 (step S125). Furthermore, the processing apparatus 10 performs an appropriate evacuation route search and a necessary fire extinguishing equipment (sprinkler 60, etc.) selection process based on the estimation result of the flame and smoke generation location and the prediction result of the flame and smoke traveling direction. (Step S125).

  Here, a suitable evacuation route is a route which can be kept away from flames and smoke, for example. The only fire extinguishing equipment required may be the sprinkler 60 provided near the flame location. That is, the sprinkler 60 in a place where only smoke exists or where no flame or smoke is generated can be removed from the necessary fire extinguishing equipment. In addition, the necessary fire extinguishing equipment may be only the sprinkler 60 provided near the place where the flame is generated and the sprinkler 60 installed at a place on the flame traveling direction side of the place where the flame is generated.

  FIG. 5A is an explanatory diagram of the control of the guide light 50 by the processing device 10, and FIG. 5B is an explanatory diagram of the control of the sprinkler 60 by the processing device 10. The processing device 10 further performs a facility control process for transmitting only a control signal to the driving device 55 to light only the guide light 50 that guides the evacuees necessary for the driving device 55 to an appropriate evacuation route (see FIG. 5A). Step S130). That is, the processing device 10 turns off the guide light 50 that does not guide the evacuees to an appropriate evacuation route, in other words, the guide light 50 that erroneously guides the evacuees in the direction approaching the flame or guides them to the smoke. (Step S130).

  In addition, the processing device 10 detects the fire occurrence, the detailed location of the fire (for example, in which room the fire occurred based on the detection result of the fire, the estimation result of the flame and smoke generation location, and the prediction result of the flame and smoke traveling direction. ) And a guidance instruction announcement process (step S130). Furthermore, the processing apparatus 10 notifies the security company of information on fire such as fire occurrence, detailed location of the fire, images of the fire site, etc. via the Internet network (step S130).

  Moreover, the processing apparatus 10 performs the equipment control process which transmits only a control signal to the drive device 65, and operates only the fire extinguishing equipment (sprinkler 60) required for the drive device 65 (refer FIG. 5B) (step S135). Further, the processing device 10 selects the necessary smoke exhausting equipment 70 based on the estimation result of the flame and smoke generation location and the prediction result of the flame and smoke traveling direction, and transmits a control signal to the driving device 75 to drive it. Equipment control processing for operating the smoke exhausting equipment 70 necessary for the device 75 is performed.

  The processing device 10 repeats the processing from step S120 to step S130 and step S135 at predetermined time intervals as long as flame and smoke can be detected in step S120. And the processing apparatus 10 changes the guide light 50 to light, the content of the guidance instruction | indication, and the sprinkler 60 to operate | move according to the fire condition which changes every moment.

  By the way, if flame or smoke cannot be detected in step S120 (No in step S120), there is a possibility that the fire has become so large that flame and smoke cannot be detected. For this reason, the processing apparatus 10 transmits a 2nd threshold value to the fire detector 30, if flame or smoke cannot be detected in step S120. The detection unit 32 of the fire detector 30 changes the fire determination threshold from the first threshold to the second threshold, and determines whether or not the fire determination value of the fire detector 30 exceeds the second threshold (step) S160).

  If the fire detector 30 determines that the fire determination value exceeds the second threshold value in step S160 (Yes in step S160), the fire detector 30 performs a normal fire alarm issuing process and rings the alarm device 40 (step S150). Moreover, the fire detector 30 performs a process of operating all the sprinklers 60 (step S150). On the other hand, if the fire detector 30 determines in step S120 that the fire determination value of the fire detector 30 does not exceed the second threshold (No in step S160), the fire detector 30 transmits the result to the processing device 10. Then, the processing apparatus 10 tries to detect the flame and smoke images again (step S115).

  The processing apparatus 10 according to the above-described embodiment can perform normal monitoring by the monitoring camera 20 without performing fire detection by the non-fire monitoring process in the first monitoring mode. Further, the first monitoring mode can be switched to the second monitoring mode by the switching process, and the fire detection based on the captured image of the monitoring camera 20 can be performed by the fire detection process in the second monitoring mode. Therefore, intruders and suspicious persons can be monitored and fire can be detected only by the processing device 10 without providing a camera for fire detection separately from the monitoring camera 20.

  Moreover, the processing apparatus 10 will switch a 1st monitoring mode to a 2nd monitoring mode, if the fire determination value (detection value) of the fire detector 30 exceeds the 1st threshold value lower than a 2nd threshold value. Then, the processing device 10 performs image processing (fire detection processing) for detecting flame and smoke in the second monitoring mode. For this reason, it becomes possible to detect a fire early compared with the case where it is determined that a fire has occurred when the second threshold value is exceeded.

  Further, the processing device 10 determines an appropriate evacuation route based on the detection result of flame and smoke by image processing, and guides only the guide light 50 arranged along the appropriate evacuation route. A process for controlling the lamp 50 is performed. For this reason, an evacuee can be prevented from evacuating accidentally in the direction of flame or smoke. Moreover, the processing apparatus 10 performs the process which selects the sprinkler 60 required for fire extinguishing based on the detection result of a flame, and controls the sprinkler 60 so that only the said sprinkler 60 extinguishes. For this reason, initial fire extinguishing can be performed only with the sprinkler 60 necessary for fire extinguishing, and the cost and labor required for restoration can be suppressed.

[Modification]
The present invention is not limited to the above-described embodiments, but is defined by the scope of the claims, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims.
(1) For example, as shown in FIG. 6, the processing apparatus 10 switches the normal monitoring mode (first monitoring mode) to the fire detection mode (second monitoring mode) every predetermined time period to emit flames and smoke. Image processing for detection may be performed. In this case, if a fire cannot be detected in the second monitoring mode, the mode is switched again to the normal monitoring mode (first monitoring mode). If a fire is detected, the fire detection mode continues to predict the flame and smoke in the fire detection mode. The smoke generation location is estimated, the guide light 50 along the appropriate evacuation route is turned on, and the necessary sprinkler 60 is operated.

(2) Moreover, if the processing apparatus 10 can detect a flame and smoke in 2nd monitoring mode, while performing the image process which estimates the advancing direction of a flame and smoke, in parallel with this, recognition of an evacuee, and an evacuee Image processing may be performed to determine the evacuation direction. In this case, information on the evacuation situation can be obtained, and this information can be used for rescue operations by transmitting it to the security company through the Internet.
(3) Moreover, if the detection method of a flame and smoke and the estimation method of the progress method are methods using the visible image imaged with a normal security camera, they will not be restricted to an above-described method.

  (4) In addition, in step S140 and step S160 of the second monitoring mode, the processing apparatus 10 sets the fire determination threshold value constant as shown in FIG. 7 instead of setting the fire determination threshold value of the fire detector 30 high. The ratio (sensitivity coefficient) between the output value of the sensor and the amount to be measured (the amount of smoke) may be insensitive. In this case, the processing device 10 determines whether or not the detection value output from the sensor 31 set to a sensitive sensitivity in step S105 exceeds a certain threshold value. Then, when determining that the detected value has exceeded a certain threshold value, the processing device 10 switches the first monitoring mode to the second monitoring mode in step S115.

(5) Note that some functions (such as the detection unit 32) of the fire detector 30 may be included in the processing device 10. In this case, the fire detector 30 transmits the output value of the sensor to the processing device 10 as detection information.
(6) The monitoring camera 20 may be a PTZ camera, and the processing device 10 may be a camera for tracking a suspicious person in addition to image processing for storing a captured image and detecting a person in the first monitoring mode. Control processing may be performed.
