The national "safety production month" in 2022 was launched in Beijing

The theme is "abide by the safety production law and be the first responsible person"

On May 31, the office of the safety committee of the State Council and the emergency management department held a video conference on the launch of the national "safety production month" in Beijing. Wang Yong, State Councilor and deputy director of the safety committee of the State Council, attended and announced the launch of the national "safe production month" in 2022. Huang Ming, deputy director of the safety committee of the State Council and Minister of the emergency management department, presided over the meeting. Wangzhiqing, deputy director of the safety committee of the State Council and Deputy Secretary General of the State Council, attended the meeting.

June this year is the 21st national "safety production month", with the theme of "observing the safety production law and being the first responsible person".

At present, at the end of the three-year national special rectification of work safety, the intensity of centralized rectification of safety risks has been raised again. Safety production is the bottom line, the red line and the lifeline of the city.

There are many pressure regulating boxes, pressure regulating cabinets, valve wells and other confined spaces distributed in the underground gas pipeline 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 lifelines, but also the key nodes for gas pipelines to connect residential users.

In order to maintain the safe operation of the city's lifeline and make every effort to do a good job in safety prevention, Hanhai technology group, in cooperation with the Chinese Academy of Sciences, undertook the industrialization of laser absorption spectrum gas detection technology, a major national special scientific research achievement. In 2021, Hanhai technology group 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 lifelines.

Its independently developed laser gas leakage monitor solves the problem of urban gas safety blind spot. It can be used at important nodes before gas pipelines such as surge tank, surge tank and valve well enter the house. Build the last defense line for household gas safety.

Facing the blind spot 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 above ground and underground space.

The laser gas leakage monitor has overcome the technical bottleneck of convenient power supply on the ground and underground integration of water flooding resistance, corrosion resistance, high precision, long service life and calibration free characteristics, and has effectively solved the technical problems of sensor measurement drift, weak transmission signal in underground space and long-term low-power operation.

Thinking 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 severe 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 applications.

Laser gas leakage monitor

In view of the above problems, the laser gas leakage monitor has achieved the following technological breakthroughs:

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.
