Gray value at plain coordinate obtains multiple gray value differences.It takes absolute value, obtains more respectively for multiple gray value differences
A absolute difference.Multiple absolute differences are added, the difference value is obtained.
Illustratively, since two infrared images are continuous, so the change procedure of flare can be embodied.If two
The difference value of Zhang Suoshu bianry images is less than or equal to preset discrepancy threshold, then illustrates the flare identified when certain
In, variation is little or does not change.At this moment illustrate that the flare identified is a wrong report.Because of infrared image and common coloured silk
Color image is compared, although the infrared signature of apparent field landscape can be captured, cannot exclude such as substation and high-tension bus-bar
Deng the source of infrared radiation of no fire hazard and the interference of its reflection on minute surface.If the difference value of two bianry images
More than preset discrepancy threshold, then illustrate the flare identified within the regular hour, variation is bigger, and fire will be carried out by having reached
The condition that calamity reports.
The communication module 15, for the warning message received and the visible images to be sent to the fire
Calamity alarm platform.
Illustratively, the warning message may include：The location information in the region to be identified and the transmission alarm
The time of information.
Illustratively, the communication module 15 may include GPRS module.
In the embodiment of the present invention, forest fire identification device and the communication of fire alarm platform, device include：Smokescope is believed
Cease acquisition module 12, processor 11, infrared image acquisition module 13, visible images acquisition module 14 and communication module 15；Institute
It states smokescope information acquisition module 12 and the processor 11 connects, for collected smokescope information to be sent to institute
State processor 11；The infrared image acquisition module 13 and the processor 11 connect, and are used for collected about to be identified

To the infrared image about region to be identified be sent to the processor 11, the visible images acquisition module 14 is used for will
The collected visible images about the region to be identified are sent to the processor 11, and the processor 11 is for working as institute
When stating smokescope information more than preset smoke density threshold value, determine that acquisition exists at the time of receiving the smokescope information
The continuous infrared image of two frames received after the moment, two ashes are respectively obtained according to infrared image described in two frames
Degree figure carries out two-value processing to two gray-scale maps respectively using preset two value-based algorithm, two bianry images is obtained, by two
Zhang Suoshu bianry images are compared, will alarm if the difference value of two bianry images is more than preset discrepancy threshold
Information and the visible images are sent to the communication module 15, the alarm that the communication module 15 is used to receive
Information and the visible images are sent to the fire alarm platform, and the fire alarm platform receives the warning message
After the visible images, so that it may to carry out fire-extinguishing operations to the region to be identified.It is filled since the forest fire identifies
It sets and smokescope is detected first, after the smokescope information is more than preset smoke density threshold value, then to two frames
The continuous infrared image is handled, and is judged whether with forest fire, when judging that forest has occurred in region to be identified
After fire, the warning message and the visible images are sent to the fire alarm platform, the fire alarm platform
After receiving the warning message and the visible images, so that it may to carry out fire-extinguishing operations to the region to be identified.Due to
The forest fire identification device begins to that forest fire is identified, avoids when dense smoke occurs in region to be identified
Existing forest fire identification device, can only identify flame when flame becomes bigger, so start into
Row alarm, so as to cause forest fire identification process not in time the problem of, therefore, alleviate forest existing in the prior art
Fire identification process not in time the technical issues of, reached improve forest fire identification process promptness technique effect.
