Description
Technical field
The present invention relates to flame detecting apparatus field, particularly relate to a kind of image-type flame detector.
Background technology
Flame detector is conventional fire-fighting equipment, for fire alarm and startup automatic spraying device.Infra red flame is visited
Surveying the infrared sensor that device uses, it by being converted into the telecommunications of varying strength by the infrared energy that different wave length naked light radiates
Number, the signal of telecommunication that infrared flame detector detects according to sensor identifies whether with the presence of naked light；By specific circuit
The signal of telecommunication that infrared sensor is produced carry out impedance matching, amplify, the method such as filtering processes, single-chip microcomputer collects infrared sensing
The signal of device, in conjunction with corresponding fire software algorithm, accurately judges the generation of fire, and sends alarm of fire signal.
When fire occurs, the infrared ray of naked light Fire Radiation is concentrated mainly in mid-infrared spectral range.Hydrocarbon
Produced naked light when fire occurs, has its distinctive spectral characteristic.Burning things which may cause a fire disaster release energy across ultraviolet, visible ray and
The infrared electromagnetic radiation wave band that waits, and major part energy concentrate on infrared band, different wave length infrared energy different.Naked light
The another one key character of flame is that its emittance has scintillation effect.Though the impact of the surroundings such as flicker frequency wind-engaging,
But it is basic within the scope of 0.5Hz to 30Hz.And the infrared radiation spectrum that hot object sends both had been different from the spoke that flame sends
Penetrate spectrum, the most not there is the blinking characteristic of flame.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical problem to be solved is for providing the figure of a kind of accurate positioning
As type flame detector.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is:
A kind of image-type flame detector, including imaging lens A1, CCD camera plate A2, cube beamsplitter 3, imaging lens
B4, CCD camera plate B5, pedestal 6, described CCD camera plate A2 and CCD camera plate B5 is vertically mounted on pedestal 6, described CCD phase
Machine plate A2 and CCD camera plate B5 is disposed adjacent, and is arranged in a mutually vertical manner, and described imaging lens A1 is connected with CCD camera plate A2, described
Imaging lens B4 is connected with CCD camera plate B5, before described cube beamsplitter 3 is built up in imaging lens A1 and imaging lens B4
End, and be connected with pedestal 6.
Further, described imaging lens A1 is goggles, convex lens or concavees lens.
Further, described imaging lens B4 is goggles, convex lens or concavees lens.
Further, it is provided with semi-transparent semi-reflecting plated film in described cube beamsplitter 3.
The beneficial effects of the present invention is: 1. rely on optical hardware device, can real-time, accurate and parallax free reading with
The different light spectrum image-forming informations of one object；2. the position in visible images and infrared image has crash consistency, operation letter
Just, once focus；3. recognizer can analyze the visible ray of same object and the imaging of infrared spectrum simultaneously.Multi-information acquisition
Analyzing, dual confirmation makes recognition result more accurate, the false alarm rate of reduction；4. due to the Complete Synchronization in the visual field, i.e. user
Zones of different, system can be selected in visible images to analyze the most corresponding infrared spectroscopic imaging the most simultaneously,
Therefore, when there is interference source in the visual field, when detector false triggering, this detector can be selected in the visible ray visual field by manual
(region can be square, and circular or any customization shape area, software algorithm is respectively in visible photoetching to select shielding area
The data in this region are got rid of inside infrared picture data), will no longer have alarm, due to light path design in shielding area
Particularity so that position in visible images and infrared image, the region of the shielding of selection has crash consistency；⑤
Accurate subregion warning function can be set, different monitored areas can be defined on visible images so that it is be corresponding different
Relay output node, thus this image flame detector possesses the function reported to the police in point accurate subregion.

Below in conjunction with embodiment, the present invention is described in further detail, but the invention is not restricted to given enforcement
Example:
A kind of image-type flame detector, including imaging lens A1, CCD camera plate A2, cube beamsplitter 3, imaging lens
B4, CCD camera plate B5, pedestal 6, described CCD camera plate A2 and CCD camera plate B5 is vertically mounted on pedestal 6, described CCD phase
Machine plate A2 and CCD camera plate B5 is disposed adjacent, and is arranged in a mutually vertical manner, and described imaging lens A1 is connected with CCD camera plate A2, described
Imaging lens B4 is connected with CCD camera plate B5, before described cube beamsplitter 3 is built up in imaging lens A1 and imaging lens B4
End, and be connected with pedestal 6.
Principle: light source projects is on cube beamsplitter 3, it is seen that light directly can be incident upon visible by cube beamsplitter 3
On light CCD camera plate, and infrared light projects on infrared light CCD camera plate by refraction so that different CCD obtain and receive difference
The spectrum of wave band imaging.
