Industrial Gas Safety Monitoring System
System Introduction
The IGSM System is a set of intelligent safety monitoring system developed based on TDLAS laser technology. The application of laser gas detection technology
enables the IGSM system to solve the pain points of traditional technology products such as high negative rate, large project investment, large maintenance, high
management difficulty and high construction risk. Can be widely used in metal smelting, petrochemical, glass ceramics, electric power, metallurgy, pharmaceutical, food, tobacco and many other industrial fields, the IGSM system topology diagram is shown below.

Laser‑sensing risks, intelligently guarding industrial safety.
Combined with the on-site pain point needs and related technical analysis,
the project team adopted laser gas detection technology as the design basis
and formulated targeted solutions, as follows :
Using the reflection characteristic of laser, the special
position can be monitored at a long distance without
contact

Natural Gas Safety Monitoring System
System Characteristic
The NGSM System is composed of laser methane detection equipment, control cabinet and system software, among which the laser methane detection equipment
is the core equipment of the NGSM System. The product is designed based on TDLAS laser gas detection technology, and the absorption amount of light molecule
gas of specific wavelength is analyzed and calculated by harmonic algorithm, so as to realize long-distance and non-contact methane gas detection. The NGSM
System can realize real-time monitoring and early warning of natural gas leakage disasters and realize 7×24 hours unattended, which can not only improve the
inspection efficiency, reduce the pipeline monitoring cost, but also avoid the safety risks caused by human negligence and error. Once the production unit leaks,
on-site personnel can obtain relevant information in the first time. Implement security measures and emergency plans in a timely manner. The following shows
the system topology.
