In order to fully curb the occurrence of major production safety accidents and escort the victory of the 20th National Congress of the Communist Party of China, the special supervision and inspection of "urban operation · escort" in Beijing (gas field) was officially launched. On the morning of April 13, the office of the municipal Safety Committee organized the municipal emergency response Bureau, the Municipal Urban Management Committee and the municipal urban management and Law Enforcement Bureau to hold a mobilization meeting for supervision and inspection.

Meeting content

The company made an in-depth analysis of the overall situation of the production and management of liquefied gas enterprises in Beijing, and made an in-depth report on the existing problems of liquefied gas enterprises in each stage.

Meeting requirements

1、 we should effectively improve our understanding of work safety and firmly establish the concept of safe development. We should highly unify our ideological understanding with the important instructions of the general secretary, fully realize the arduousness and complexity of work safety in the field of urban operation, and resolutely implement the work requirements of the municipal Party committee and the municipal government.

2、 Is to effectively improve the understanding of the supervision and inspection work to ensure that the supervision work has achieved tangible results. The municipal gas group and Beiran industrial group shall earnestly raise awareness and cooperate with the work of safety production supervision and inspection. The supervision and inspection team shall adopt the method of "stationed supervision and anatomical law enforcement", do a good job in this supervision and inspection according to law and regulations, and supervise and guide the enterprises to implement the main responsibility.

3、 we should effectively improve our understanding of the rectification of hidden dangers and fully implement the main responsibility of enterprises. For potential problems that can be implemented and changed, the responsible unit shall implement the rectification quickly and report the rectification results in writing in a timely manner. For problems and hidden dangers that cannot be rectified immediately, the group shall take the lead in studying and formulating special rectification plans, and implement the responsible units, responsible persons, rectification measures and completion time limit one by one. After the supervision, we should draw inferences from one instance and establish a long-term improvement mechanism from point to area.

The special supervision and inspection of the city's "city operation · escort" in the gas field will last for 4 weeks, and will be carried out in the way of "stationed supervision and anatomical law enforcement". After the mobilization meeting, the supervision working group will immediately enter the "in-house supervision" stage to ensure the orderly development of all work.

In 2015, Hanhai optoelectronics established the world's first laser telemetry monitoring network for Beijing gas, China's largest gas company, to realize 24-hour remote on-line gas leakage monitoring of all high-pressure regulating stations of Beijing gas. It realizes synchronous video monitoring while online monitoring the leakage of natural gas equipment, which greatly reduces the labor intensity of inspectors and improves the management efficiency while ensuring the production safety in real time.

Through laser absorption spectrum gas detection technology, Hanhai photoelectric can solve the problems of instability, easy interference and high false alarm rate of traditional gas detectors. Corresponding products help gas enterprises improve safety management level, improve operation management efficiency and reduce management cost.

Fixed scanning laser gas telemeter

The f

01 visual intelligent monitoring

Combined with high-definition video, the on-site concentration data can be monitored 24 hours remotely. Realize all-round detection of trace gas leakage and accurate judgment of leakage direction.

02 wide detection area

The fixed scanning laser gas telemeter can conduct 360 degree rotation scanning on the area with a radius of 300m, and can monitor the leakage in the target area of 280000m2 at most. Suitable for large-scale operation.

03 preventive monitoring

Different from the passive waiting of the traditional detection mode, it actively monitors the leakage risk points. The response time is only 0.1 second, which can accurately detect ppm micro leakage. Truly realize the preventive monitoring of gas leakage.

04 night vision infrared system

Night vision infrared system, 2 million pixels, 25X optical zoom.

05 high integration

With the integrated design of detector, camera and PTZ, the equipment can operate independently. Without the control of other equipment, it can complete the scanning movement, detection and alarm functions and communicate with the upper computer.

06 key area monitoring can be set

Key areas such as key flange joints and valves can be monitored, and different scanning modes can be set to realize no dead angle monitoring of important areas and key points.

07 strong anti-interference ability

Compared with the traditional detector, which is easy to be disturbed by environment and cross gas, it has strong anti-interference ability. Fingerprint detection, truly achieve zero false positives.

08 "0" maintenance

The product does not need to be adjusted, which can save the operation cost in the whole life cycle.

09 long service life

The product has good stability without regular adjustment and maintenance, and its service life is up to 20 years.

system configuration

In addition to the production safety in the station, the blind spot of the urban lifeline connecting thousands of households by gas enterprises also needs attention.

ixed scanning laser gas telemetry instrument is based on the laser absorption spectrum gas detection technology (TDLAS). It can carry out radar 360 degree rotating scanning within a radius of 300 meters to monitor the methane gas concentration. It can carry out remote online visual intelligent monitoring by means of real-time monitoring gas concentration data combined with high-definition video, and can locate the leakage direction. It is applicable to the operation occasions requiring large-scale monitoring, such as pressure regulating station.

Laser gas leakage monitor

The laser gas leakage monitor is composed of detector, power supply and communication module and monitoring platform. Laser gas leakage monitor is an aboveground and underground laser monitoring product 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 is powered by solar energy and battery, and uses intelligent monitoring system with ultra-low power consumption and long-term operation

Line time to promote effective monitoring of end links.

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
