Abstract
The present invention provides a kind of infra red flame detecting module principle and preparation method, use indium antimonide materials, by being fixedly mounted on the photosensitive element chip with indium column contact array on the silicon reading circuit plate with indium sheet array using computer processor mounting means, face plated film before the detectors, the band logical film of 6 6.5 microns of transmissions is selected, realizes and 6 microns to 6.5 microns of infrared light is converted into electric signal by module.This module has simple production process, is swift in response, is of low cost, applicable various environment.
Description
Technical field
The present invention relates to a kind of infrared electro Detection Techniques, in particular to a kind of atmospheric attenuation band detector detection flame
Technology.
Technical background
All objects higher than absolute zero (- 273 DEG C) all can be constantly to surrounding space radiated electromagnetic wave.And radiate
Temperature of the size of energy to object in itself is directly proportional, the inevitable rise with local temperature of burning of any material, therefore meeting
The electromagenetic wave radiation of some strength is produced to surrounding.Sensor measurement radiation letter is utilized according to Planck blackbody radiation law principle
Number, it is possible to judge the generation of flame.But the infra-red radiation containing 3 atmospheric windows in daylight, so common infrared biography
Sensor flame detection modules can not antisum interference.What is largely used at present is exactly 8-14 microns of Long Wavelength Infrared Sensor detection fire
Flame, interference and false-alarm problem inevitably occurs in it in sight environment.We use a wave band outside atmospheric window,
That is atmospheric attenuation wave band 6-6.5 microns of detector, the non-atmospheric window flame detecting module of development daylight would not occur again and do
The problem of disturbing, can accurately, quickly judge flame.
The content of the invention
Present disclosure is that infrared detection module uses the silicon reading circuit plate with indium sheet array as substrate, will
Indium antimonide photosensitive element chip with indium column contact connects mode and connects, and the power information of output is transferred to gain puts
In big circuit, the output of module information is realized by comparing output voltage values and frequency.Face plated film before the detectors at the same time, choosing
The band logical film of 6-6.5 microns of transmissions is selected, develops the non-atmospheric window detector module for only having response to 6-6.5 micron wavebands,
For detecting flame without false alarm false-alarm in daylight environment.
Brief description of the drawings

Embodiment
1, by with silicon reading circuit of the indium antimonide photosensitive element chip of the indium column contact alignment with indium sheet, utilize flanging work
Tool is fixed, and judges whether contact is normal and complete using computer by contact voltage output.
2, after judging that contact is normal, product module is moved under inert gas shielding carry out indium antimonide photosensitive element chip and
The injecting glue on silicon reading circuit periphery, to protect indium column contact and ensure clearance space cleaning.
3, physical protection processing is carried out to photosensitive element chip.
4, reading circuit and gain amplifying circuit are connected, realizes that data are amplified.
5, face plated film, selects the 6-6.5 microns of band logical films passed through before the detectors.
