Recently, Su Jie, director of the Safety Coordination Department of the emergency management department and spokesman, pointed out at a briefing held by the state information office that during the "14th five year plan" period, guide key cities across the country to accelerate the construction of comprehensive monitoring and early warning platforms for urban safety risks, so that all localities can "monitor, early warning and quickly deal with the risks of gas and related urban lifelines".

There are many closed spaces such as pressure regulating boxes, pressure regulating cabinets and valve wells distributed in the underground gas pipe network of the city. In case of gas leakage at these locations, it is very easy to form gas accumulation, resulting in potential safety hazards and accidents. These places are not only the important links of urban underground lifeline, but also the key nodes for gas pipelines to connect residential users.

Aiming at the safety blind spot of urban lifeline, Hanhai optoelectronics has launched a relevant solution - a series of combustible gas laser monitoring products of the 

Internet of things.

The combustible gas laser monitoring series products of Internet of things are composed of detector, power supply and communication module and monitoring platform. Internet of things combustible gas laser monitoring series products are aboveground and underground laser monitoring products integrating laser absorption spectrum gas detection technology (TDLAS), low-power technology and Internet of things technology. This series of products are applicable to urban gas pressure regulating box, pressure regulating cabinet, valve well and unattended station. It is transmitted to the monitoring platform through NB lot Internet of things communication to realize real-time, fast, long-distance and accurate monitoring of trace gas leakage above the ground, underground, closed and semi closed spaces. It is the best blind spot solution for urban gas safety, so as to control the overall safety situation of urban gas and help the safety protection system of urban lifeline.

01 low power consumption

The laser gas leakage monitor of the Internet of things adopts solar energy and battery power supply, and uses intelligent monitoring system, ultra-low power consumption and ultra-long operation time to promote the effective monitoring of the end link.

02 preventive monitoring

The response time is less than 10 seconds, which can accurately detect ppm trace gas leakage, upload the monitoring and alarm data to the cloud platform, make the gas concentration data display more intuitive, help the full coverage monitoring of urban gas leakage, and truly realize the preventive monitoring of gas leakage.

03 easy installation

The modular design from detector to control system is adopted. The simplified system structure makes the installation easier.

04 strong anti-interference ability

It will not be disturbed by humidity, dust, temperature and other gases, and can work in high humidity environment for a long time.

05 omnidirectional NB lot Internet of things access

Using Internet of things technology, all areas covered by the network can be used without limitation of distance and scope.

06 waterproof alarm function

The water level monitoring function can monitor the accidental water inflow in the valve well in real time.
