Description
Technical field
This utility model is related to hazardous gas security preventer field, more particularly to a kind of indoor hazardous gas Terahertz
Detector.
Background technology
China step into it is industrialized simultaneously, Chinese etesian industrial accident is also occurring repeatedly.Colliery is quick-fried
Such news report such as fried, Factory Building is on fire, workman's poisoning emerge in an endless stream.These accidents are primarily due to be made in industrial environment
Caused with inflammable and explosive, toxic and harmful is improper.As the term suggests gas alarm is exactly gas leakage detection warning instrument.When
In industrial environment during flammable or release of toxic gas, blast is reached or alarm of being poisoned when gas alarm detects gas concentration
During the critical point of setting, alarm will send alarm signal, to remind work to take safety measures, and drive air draft, cut-out,
Spray system, prevents blast, fire, intoxication accident so as to guarantee safe production.
Gas alarm product is broadly divided into industrial gas alarm and home-use gas alarm, industrial gas report
Alert device is again comprising stationary gas alarm and portable gas detector.Below with regard to stationary gas alarm, Portable gas
Body detector and home-use gas alarm are introduced explanation.
Industrial fixed gas alarm is made up of alarm controller and detector, and controller can be positioned over night shift room
It is interior, mainly control is monitored to each monitoring point (namely detector), detector is installed on the place that gas is most easily revealed, its
Core component is built-in gas sensor, the concentration of gas in sensor detection air.Detector detects sensor
Gas concentration is converted into the signal of telecommunication, and by cable transmission to controller, gas concentration is higher, and the signal of telecommunication is stronger, works as gas concentration
When meeting or exceeding the alarm point of alarm controller setting, alarm sends alarm signal, and can start electromagnetic valve, exhaust fan etc.
Peripheral equipment, excludes hidden danger automatically.
THz ripples (THz wave) or referred to as THz rays (Terahertz ray) are the just quilts from the eighties of last century middle and late stage eighties
Definite designation, before this scientists will be referred to collectively as far ir ray.THz wave refers to frequency in 0.1THz to 10THz
The electromagnetic wave of scope, wavelength probably 0.03 to 3mm scopes, between microwave and it is infrared between.
As soon as in fact, before 100 years, there is scientist to be related to this wave band.At 1896 and 1897,
Rubens and Nichols relate to this wave band, and infrared spectrum reaches 9um and 20um, there is the record for reaching 50um again afterwards.
Last 100 yearses time afterwards, far-infrared technique achieves many achievements, and industrialization.But it is related to terahertz wave band
Result of study and data are considerably less, are mainly limited by effective Terahertz generating source and sensitive detector, therefore this ripple
Section is also referred to as THz gaps.
With the series of new techniques eighties, the development of new material, the development of particularly ultrafast technology so that obtain broadband
Stable pulse THz sources become a kind of quasi- routine techniquess, and THz technologies are developed rapidly, and interior at the international level start one
THz research booms.
At present, terahertz emission reached in the world following common recognition, i.e. Terahertz be it is a kind of it is new, have many unique excellent
The radiation source of point；Terahertz Technology is a very important intersection Disciplinary Frontiers, to technological innovation, the national economic development and state
Family has safely provided a very tempting opportunity.Why it can cause people widely to pay close attention to, have so many answering
With, firstly because the tera-hertz spectra of material includes the physics and chemical information for enriching very much, so research material is at this
The spectrum of wave band is significant for the exploration of the structure of matter；Secondly because terahertz pulse light source and conventional light source phase
Than with many unique properties.The reason for people's concern THz technologies is THz ray generally existings, is people's knowledge of natural environment circle
Effective clue and instrument.But relative to the electromagnetic wave of its all band is such as infrared and microwave, to its understanding and using non-
It is often deficient.Absorption of many nonmetallic non-polar materials to THz rays is less, therefore with reference to corresponding technology so that detection
Material internal information is possibly realized.For example, ceramics, hardboard, plastic, foam etc. be to THz electromagnetic radiation it is transparent, because
This THz technology can be as the unionized of x-ray and relevant complementary radiation source, for the safety prison in the place such as airport, station
Survey, such as detect hiding smuggled goods and weld situation including firearms, explosive and drugs etc., and for integrated circuit
Detection etc..Polar substancess are stronger to the absorptance of THz electromagnetic radiation, particularly water, should adopt various measures in THz spectral techniques
The impact of moisture is avoided, but in THz imaging techniques, it is possible to use this characteristic differentiates the different conditions of biological tissue, than
Such as the distribution of fat and muscle in animal tissue, the degree of injury of human body burned part, and the moisture of plant leaf blade tissue are diagnosed
Content distribution etc..THz imaging technology compared with the imaging technique of its all band, the resolution of the detection image obtained by it
(ultrasonic, infrared, x-ray technology can also improve image resolution ratio, but millimeter-wave technology is but to have significantly increase with the depth of field
It is not significantly improved).In addition Terahertz Technology also has the characteristic of many uniquenesses, such as there is less dissipating in material heterogeneous
Penetrate, can detect and measure moisture content etc..Not only signal to noise ratio is high for terahertz light spectral technology, and promptly sample can be constituted
Slight change make analysis and differentiate, and terahertz light spectral technology is a kind of noncontact measurement, is enabled it to half-and-half
The physical message of conductor, thin dielectric film and body material is fast and accurately measured.In view of the characteristics of THz rays, will give
Far-reaching influence is brought in the fields such as communication, radar, astronomy, medical imaging, the identification of biochemistry article, materialogy, safety inspection,
And then the productive life of change people.There is article《The research of THz communication technology and prospect》,《Chinese laser》, 2009,36
(9)：2213-2233 susceptible of proof above characteristics.
Indoor hazardous gas detection means presence sensing species common on market is not enough, the not high enough problem of sensitivity,
So need a kind of detection species wider, the higher hazardous gas detection means of sensitivity.
《The terahertz time-domain spectroscopy research of carbon monoxide》Hu Ying etc., 1000-0593 (2006) 06-1008-04, just introduces
The terahertz light spectral property of carbon monoxide.
