Further illustrating as the present invention, described display is light-emitting diode display.
The control method of described flame identification survey meter, comprises the following steps:
Step one, connects civil power by power supply adaptor, clicks on & off switch, and flame identification survey meter enters duty.
Step 2, clicks reset key, and photographic head carries out brightness, saturation, contrast, limit by collection image and to image
Edge enhancing and Gamma correction etc. process, and the infrared fileter that photographic head is installed will utilize the spectral signature of Initial Stage of Fire flame
With spectral radiance feature, image being carried out ELIMINATION OF ITS INTERFERENCE, photographic head is again by image transmitting to central processing unit, through central processing unit
Output shows image the most in real time, and central processing unit will intercept 5 two field pictures continuously and store according to certain frequency simultaneously
In memorizer, and view data being carried out judgement process, occur if any fire, central processing unit controls buzzer and pronounces continuously；
As not having fire to occur, central processing unit controls this 5 two field picture of memory clear-up, and central processing unit will be again according to certain frequency
Intercept 5 two field pictures continuously to be identified judging.
Step 3, as released alarm of fire, clicks reset key, and buzzer stops pronunciation, photographic head Resurvey figure
Picture.
Step 4, clicks on & off switch, and power supply adaptor cuts off civil power, and flame identification survey meter quits work.
The beneficial effect that the present invention possesses:
1, described flame identification survey meter has extremely low rate of false alarm, and can correctly remove all kinds of obstacles.
2, described flame identification survey meter uses image to identify fire disaster flame, than the conventional fire detection using sensor
The accuracy of instrument is high.
3, described flame identification survey meter employing photographic head is as signals collecting instrument, because photographic head is contactless,
Do not affected by ambient temperature, the most not by spacial influence, installation environment is required relatively low.
4, described flame identification survey meter is simple to operate, safe and reliable, it is simple to promote.
