Principle:
The system analysis host is based on infrared spectroscopy technology, has pulse infrared light source, and forms 10 spectral bands in mid-infrared region through narrow-band optical filter for gas analysis; ultra-high sensitivity patented optical technology with enhanced beam can be realized through 10 narrow-band optical filters, and ultra-narrow optical filter can remove the interference of background gas; Multi-spectral region can help to minimize the cross sensitivity. It can measure up to 9 kinds of gases at the same time.
Multi-point sampler can freely expand gas sampling points from 12 channels to 64 channels. The instrument can be applied to small flow gas sampling and high temperature gas working conditions. Configuration and control are carried out by the application software on Win-PC, and data are automatically stored in Excel format. Standard digital or analog output is realized through different interfaces. At the same time of 64 channels of simultaneous sampling, 64 channels of temperature sensor and pressure sensor can be connected to the multi-point sampling unit to measure the sampling gas temperature, air temperature, surface temperature, working temperature and pressure of the multi-point sampling unit.

Functions:
a)The function of using database to analyze the change of gas content in a monitoring point in a period of time;
b)Prediction function of spontaneous combustion fire:by calculating the concentration of each component,alkane-alkene ratio and chain alkenes ratio,timely and accurately reflect the change of fire source temperature;by using triangular rule to discriminate the degree of explosion danger;
C)Historical data query function:system data storage for more than ten years.Provide various data for fire prevention and extinguishing;
d)Automatic control function:It has 24-hour online monitoring function and realizes networking monitoring function.It can install the system on the computer of employees in the enterprise,and has real-time viewing function.The output function of the system is complete:the gas sampling control cabinet can automatically sample 60 sampling points,analyze the gas concentration,store the analysis data by computer,calculate the relevant parameters,and send out spontaneous combustion alarm;
e)The functions of report,curve,storage and printing.It can provide daily,monthly,spectrogram graph and gas content trend reports.
f)The functions of automatic alarm of gas concentration exceeding the setting limit,flow display and automatic adjustment.
g)It has the function of networking,realizes the sharing of analysis data,facilitates the leaders and dispatchers to directly detect the changes of underground gas,and can be monitored by APP on the mobile terminal and accessed by remote web pages.
