Japanese Patent Laid-Open No. 8-126404

  However, the interlocking signal that the monitoring device exchanges with the crime prevention equipment is generally a signal condition that is on and off, but the disaster prevention equipment functions in several stages other than on and off. There are not a few facilities. For example, a fire alarm or the like detects a signal for each level of importance according to the situation at the site, such as caution, vigilance, or fire, as a notification condition. Also, with a normal surveillance camera, if a building is filled with smoke, a person who is left behind cannot be captured. In addition, in an emergency, the flow of people is concentrated in one place due to the confusion, which can result in a dangerous situation.

  It is an object of the present invention to provide a monitoring system that enables appropriate monitoring in conjunction with crime prevention equipment.

An embodiment for solving the problem is:
A monitoring device (1) that receives image signals from a plurality of external camera devices (14) and supplies the image signals to a plurality of external monitor devices (16),
A signal from an external disaster prevention facility (12) is received, and based on the change in the signal, the image signal is supplied from a first monitor device of the plurality of monitor devices, which is different from the second monitor device. The monitoring device is characterized by being changed to a monitor device.

  According to this invention, information from an external disaster prevention facility is referred to, and this is reflected in the operation of the monitoring device. As an example, according to the disaster prevention information from the disaster prevention facility, it is necessary according to the disaster prevention situation. Camera images are supplied to the necessary monitor equipment, realizing efficient monitoring processing and reducing the burden on the supervisor.

The block diagram which shows an example of a structure of the monitoring system which is one Embodiment of this invention. The flowchart which shows an example of the report process which a monitoring system similarly performs. The flowchart which shows an example of the monitor process which a monitoring system similarly performs.

Embodiments according to the present invention will be described below with reference to the drawings.
An example of the configuration of a monitoring system according to an embodiment of the present invention will be described below in detail with reference to FIG. FIG. 1 is a block diagram illustrating an example of a configuration of a monitoring system according to an embodiment of the present invention. That is, as shown in FIG. 1, the monitoring system 1 is mainly composed of a surveillance camera control device 11 and a crime prevention facility 12. The crime prevention facility 12 is connected to the crime prevention facility 12 and the temperature rises. A fire alarm 13 for detecting a fire from the fire and notifying the crime prevention facility 12, a crime prevention sensor 13 'for notifying the crime prevention facility 12 when a warning button or the like is pressed, a sound through a sound system of the facility, etc. Broadcast equipment 18 that informs of a disaster etc. and prompts evacuation, etc., a guide light 19 that guides the direction of evacuation of the refugee, and a guide plate 20 that guides the route of the evacuation evacuation.

  Further, as shown in FIG. 1, the monitoring system 1 has a monitoring camera control device 11 and a mechanism connected to the monitoring camera control device 11 that can be rotated. Similarly, the monitoring system 1 can be rotated with a plurality of cameras 14 for monitoring. A plurality of far-infrared cameras 15 that have a mechanism and can capture images even when the far-infrared rays are filled with smoke at night or fire, etc., and when they receive images from the cameras 14 and the far-infrared cameras 15, they are output and displayed. A plurality of monitor devices 16 and an operation terminal 17 for remotely operating the monitoring system 1 and the like.

  The monitoring system 1 having such a configuration performs notification processing for evacuees and the like as shown in the flowchart of FIG. 2 below. In general, disaster prevention equipment often recognizes the situation in multiple stages.For example, a fire alarm detects a signal for each level of importance according to the situation at the site, such as caution, vigilance, or fire. is doing. Therefore, according to the stepwise situation notification from the disaster prevention equipment (for example, the normal monitoring mode in case of caution, the strict monitoring mode in case of warning, the emergency monitoring mode in case of fire), It is effective to change the handling method.

  That is, as an example, the monitoring camera control device 11 determines whether or not a notification of the emergency monitoring mode (when a fire occurs) has been received from the crime prevention equipment 12 (step S1). When the surveillance camera control device 11 receives a notification of the emergency monitoring mode (when a fire occurs) from the crime prevention equipment 12, the image analysis unit of the surveillance camera control device 11 (not shown) uses the camera 14 or the far infrared camera 15 to send it. The supplied image signal is analyzed to detect a movement vector of the image. If the movement vector can be detected, it is determined by comparing whether or not a person is included in the image corresponding to the movement vector with an image stored in advance (step S2). If the surveillance camera control device 11 determines that a person is included in the image corresponding to the movement vector, the surveillance camera control device 11 notifies the crime prevention equipment 12, for example, together with the position information of the camera 14 that the person is included in the image (step S3). ). In the security equipment 12, when the notification indicating that a person or the like is included in the image is received from the surveillance camera control device 11, as an example, the appropriate position corresponding to the position information of the camera 14 is triggered by this notification. By driving the guide light 19 or the guide plate 20, for example, the evacuation is guided or guided to an evacuee or the like (step S4). Similarly, when the crime prevention facility 12 receives a notification from the surveillance camera control device 11 indicating that a person or the like has been included in the image, the broadcast facility 18 is used as a trigger for the evacuee or the like using this notification as a trigger. Can be guided to the other party (step S5). Thereby, the disaster prevention equipment 12 of the monitoring system 1 can guide evacuation directly to the place where the refugee exists.

  Also, with a normal surveillance camera, if a building is filled with smoke, a person who is left behind cannot be captured. In addition, in an emergency, the flow of people is concentrated in one place due to the confusion, which can result in a dangerous situation.

  In consideration of such a situation, it is effective for the monitoring camera control device 11 to consider the stepwise notification from the security equipment 12 and to change the processing based on this notification. That is, as an example, as shown in the flowchart of FIG. 3, when the monitoring camera control device 11 receives a notification of the “normal monitoring mode”, which is a normal state, from the crime prevention equipment 12 (step S11), An image from a camera near the target area is displayed on a monitor device designated in advance (step S12). However, when the surveillance camera control device 11 receives a notification of the “strict monitoring mode”, which is a state of caution received from the crime prevention equipment 12 (step S11), the surveillance camera control device 11 particularly evacuates from the images of the plurality of cameras 14. A camera image and a monitor device corresponding to a person's flow line (a flow line of an area where a predicted person is concentrated or a flow line estimated by the camera 14 in which a motion vector is detected) are selected (step S13). . Then, the image of the selected camera is supplied to the selected monitor device and displayed (step S14). As described above, only one example of the “normal monitoring mode” and the “strict monitoring mode” has been described, but regarding the notification from the crime prevention equipment 12, the “emergency monitoring mode” which is a state in which a fire is recognized, and other modes. It is preferable to recognize the above and selectively perform processing unique to each mode.

  In other cases, various modifications can be made without departing from the scope of the present invention. In short, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
