Principle and Structure

LBS-001 series battery spontaneous combustion monitoring system integrates ultraviolet absorption spectroscopy, infrared photoacoustic spectroscopy, cavity enhanced absorption spectroscopy, Fourier transform infrared spectroscopy, tunable semiconductor absorption spectroscopy, thermal conduction paramagnetic oxygen and other technologies. It is composed of sampling gas chamber/ fume collecting hood, multi-point sampler, sampling pipeline, monitoring computer, ultraviolet absorption spectrum gas analysis sensor, photoacoustic spectroscopy multi-gas analysis sensor, Fourier infrared gas analysis sensor, cavity enhanced gas analysis sensor, tunable semiconductor absorption spectroscopy gas analysis sensor, thermal conductivity/paramagnetic oxygen gas sensor, printer, system software, etc.

The system analyzer is based on infrared spectroscopy technology, tunable guided body absorption spectroscopy technology, thermal guidance technology, paramagnetic oxygen technology, has a pulsed infrared light source, and forms 10 spectral bands in the mid-infrared region through narrow-band optical filters for gas analysis. The ultra-high sensitivity is based on the patented enhanced cantilever beam optical microphone technology, which can be realized by 10 kinds of optical narrow-band filters, and the extremely narrow optical filter can remove the interference of background gas. Multiple spectral regions can facilitate minimal cross-sensitivity. 

Functions

The function of using the database to analyze the change of the gas content of a certain monitoring point over a period of time;

Spontaneous combustion fire prediction function: Through the calculation of the concentration of each component, alkene ratio and chain alkene ratio, it can timely and accurately reflect the temperature change of the fire source; use the triangle rule to judge the degree of explosion hazard;

Automatic control function: with 24-hour online monitoring function, and realize network monitoring function;

The gas sampling control cabinet can automatically sample 64 sampling points, analyze the gas concentration and calculate relevant parameters, and issue a spontaneous combustion alarm;
