Thus correctly find leak point and gas cloud cluster flies away direction.
1.4 wide spectrum detections: single pass 400～25000 wave-number range, can detect almost all of inorganic and organic gas
Body, such as ammonia, benzene and other inorganic and organic gas.Very large database includes that kind more than 400 is poisonous, hazardous gas and chemical weapons
Deng quick mensure provides accurate information report.
1.5 sensitivity are high: specially designed optical system is gathered all by the infrared light that special infrared telescope gathers
It is ensured that realizing detectable limit can reach ppm level on the burnt detector to liquid nitrogen cooling.
1.6 full-automatic identification systems special intelligent softwares:: system automatically scanning, full-automatic data acquisition and procession.Pin
To emergent, anti-terrorism particular/special requirement, develop highly intelligent special-purpose software, it is qualitative that a key can complete automatically scanning data
Quantitative analyses；When poisonous or hazardous gas is detected, sound and animation mode automatic alarm simultaneously can be passed through.
In the past many, typically bigger than various visible rays and infrared pick-up instrument of remote sensing infrared spectroscopy system volume and weight
Need to be arranged on fixed support or moveable vehicle on, tracking and measuring is done to the fixing target of small range, its mensure work is subject to
Above ground structure and the quality of road impact mensure, are difficult to make quick, accurate survey to various accidents in air on a large scale
Determine and propose counter-measure.Patented technology of the present invention is mounted in special remote sensing infrared spectroscopy system on dedicated unmanned machine,
In seconds accident in ambient air in the range of tens of square kilometres can be made with quick mensure, and judge dangerous gas
The title of body, concentration and fly away the information such as direction, thus take accurate emergency measure.
