the shooting module is a panoramic camera,
the alarm module is an alarm bell,
the power module selects a solar storage battery.
The invention discloses a forest fire prevention emergency alarm device installed at a forest district high-rise point, which comprises a main control module respectively connected with a panoramic camera, an image recognition module, a main control module and an alarm bell, and is communicated with a remote monitoring device through a GPRS module, and a power supply module supplies power through the main control module.
The panoramic camera is arranged on a rotating platform connected with a motor shaft, and the motor is driven by a main control module.
The main control module controls the motor to rotate the rotating platform at the speed of 360 degrees and 5 minutes/circle to drive the panoramic camera to periodically rotate, and simultaneously controls the panoramic camera to shoot panoramic images in a forest and store the shot panoramic images in the storage module.
The image recognition module divides the panoramic image into rectangular grids of 60 × 150-150 × 450, preferably 100 × 360; and comparing the panoramic image with the background image, identifying whether the identified image difference is a fire alarm, if so, calculating the angle and the distance of a fire alarm point relative to a monitoring point (a shooting point) according to a scale and a grid of a rectangular array block by combining the area of the difference image, and feeding back the angle and the distance to the main control module.
The main control module triggers an alarm according to the identification information fed back by the image identification module, generates alarm information including equipment ID, equipment position, abnormal pictures, time, angle and distance, and feeds back the alarm information to the remote monitoring device through the GPRS module.
After the appraisal is the fire alarm, main control module control motor stop rotating, perhaps rotate at the wide angle within range small amplitude of appraising the fire alarm, will shoot the mode and switch into the mode of making a video recording, will make a video recording the scene through the GPRS module in real time and convey to remote monitoring device.
After the remote monitoring personnel observe the fire alarm, the remote monitoring device can be operated, the motor rotation angle is controlled through the main control module through the GPRS module, the panoramic camera is controlled to view in real time, the shooting focal length is adjusted, or the shooting and the shooting are switched for obtaining clear real-time images. Further observing the fire alarm information on site, arranging fire fighters or patrol forest fighters in time according to the fire behavior, and extinguishing various fires and hidden fire hazards in time at a directional fixed point.
After the remote monitoring personnel observe, the person is identified as not a fire alarm, non-fire alarm information is fed back to the main control module through the GPRS module, the main control module cancels a fire alarm mode and an alarm bell, the shooting mode of the panoramic camera is switched back to the shooting mode, and meanwhile the motor is controlled to continue to rotate periodically.
In conventional remote monitoring, monitoring personnel can read panoramic images in the storage module through the main control module in any time period through the remote monitoring device.
The rotating speed of the motor and the shooting frequency of the panoramic camera can be set remotely through the control module.

During actual use, the power module can select a wind power supply to be combined with a solar power supply according to the ground topography.
When the panoramic camera is installed, the top end of trees in a forest area is taken as a reference surface, and the reference surface comprises a plane of a plain and a concave/convex slope of a hillside.
In order to effectively monitor fire and ensure the optimal shooting effect of the panoramic camera, according to the shooting performance of the panoramic camera, the vertical distance higher than the reference surface is preferably D, the inclination angle with the reference surface is theta, and the shooting range distance is D.
When a suspected fire alarm is captured, the panoramic camera is aligned to the fire alarm position in real time, receives the remote control correction position, and sends back an image according to the transmission speed of the communication channel so as to monitor the development of the fire.
According to the trend of fire development, the flame can spread gradually, and more burns, the acquired flame image can become larger gradually, according to the characteristic, when a suspected fire exists, an image sample is acquired, a suspected ignition point and a flame profile map are scanned, data are saved, the image is continuously adopted after 5 seconds, the flame profile map is acquired, the flame profile map data are obtained 3 times, whether the fire is in accordance with the fire rules or not is judged, and the fire spreading rules are as follows, for example: the outline of the image at the back surrounds more than 90% of the front (considering wind, the characteristic of each flame, and impossible to completely surround and cover), each outline is increased by 20% -50%, and the severity of the actual fire is judged by the spreading speed and the area characteristic.
The data of the image acquisition interval time, the judgment times and the spreading rule can be corrected remotely according to the actual terrain, the tree characteristics and the season.
When the characteristic matches the fire, the fire is confirmed.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
