The biggest opportunity and challenge in the 21st century is urbanization. The word "urban lifeline" has gradually come into people's vision. What is "urban lifeline"?

city lifeline

Including gas, water supply and drainage, heat, comprehensive pipe gallery and other pipeline galleries, which are an important part of urban municipal infrastructure. Their safety status directly affects the guarantee of people's livelihood and the high-quality development of urbanization.

China's urban gas pipeline network exceeds 850000 kilometers, and the urban gas safety risk is becoming increasingly prominent, especially the "June 13 ShiYan gas explosion accident in Hubei" and other major gas accidents occur from time to time, which puts forward higher requirements for ensuring the safe operation of gas underground pipeline network and adjacent underground space.

Facing the blind spot and monitoring pain point of urban gas safety

The common gas monitoring equipment in the market can not effectively and fully meet the on-line monitoring needs in the complex environment of underground space.

In cooperation with the Chinese Academy of Sciences, Hanhai optoelectronics has undertaken the industrialization of laser absorption spectrum gas detection technology, a major national special scientific research achievement. The independently developed laser gas leakage monitor has overcome the technical bottleneck of integrating water flooding resistance, corrosion resistance, high precision, long life and calibration free characteristics, and effectively solved the technical problems of sensor measurement drift, weak transmission signal in underground space and long-term low-power operation.

Shengwei thinks about building hard core products

The underground space environment has complex characteristics such as high temperature, high humidity, water logging, strong acidity and alkalinity and weak signal. The common monitoring equipment can not meet the use environment of underground space. The equipment is faced with harsh environments such as strong acid, strong alkali, high humidity, water flooding and various gas interference. How to realize long-term, online, calibration free, highly sensitive and reliable detection capability is a difficult problem for large-scale urban monitoring application.

In 2021, Hanhai optoelectronics and Shenzhen Institute of urban public safety technology established a joint R & D Center for flammable, explosive, toxic and harmful gas detection. Comprehensively contribute to the safety of urban lifeline.
