Recently, the safety committee of the State Council announced that from mid April to the end of June, the safety committee of the State Council organized 16 comprehensive inspection teams to comprehensively supervise the safety production inspection of 31 provinces (autonomous regions and municipalities directly under the central government) and Xinjiang production and Construction Corps, and simultaneously carry out the safety production and fire protection inspection of provincial governments of the State Council in 2021 and the safety production inspection of member units of the safety committee of the State Council.

   The comprehensive supervision of the national work safety inspection will focus on the implementation of the 15 measures for work safety, further promote all regions and relevant departments to truly establish and consolidate the concept of safety development and improve the responsibility system for work safety. At the same time, the work safety assessment and patrol will approve and verify the existing outstanding problems in various ways in accordance with the key points of annual assessment issued by the safety committee of the State Council All relevant departments shall make accurate evaluation on the annual work safety.

Then, more than a dozen provinces and cities such as Shandong, Jiangsu, Jiangxi and Hubei issued a notice to carry out a major inspection of work safety throughout the province.

  In addition to the carpet type safety production inspection covering many industries, Hebei, Sichuan, Gansu and other regions have carried out special safety inspection in the field of hazardous chemicals under their jurisdiction, further strengthened law enforcement inspection, and strictly prevented all kinds of accidents.

   Hanhai photoelectric can solve the problems of instability, easy interference and high false alarm rate of traditional gas detectors through laser absorption spectrum gas detection technology. Help hazardous chemical production enterprises, hazardous chemical storage enterprises and chemical parks to realize effective and real-time gas monitoring.

Fixed reflection laser gas telemeter

The fixed reflection laser gas telemetry instrument is composed of laser control unit, spectral analysis unit and optical reflection unit. It adopts laser absorption spectral gas detection technology (TDLAS) to monitor the gas concentration between the laser transceiver and the reflection device for long-distance all-weather on-line monitoring. Through the networking of multiple devices, the real-time monitoring of the distribution concentration, moving speed and moving direction of different component gases can be realized. It is an ideal choice for monitoring gas leakage in a wide range of open areas. It is very suitable for the scenario application of hazardous chemical production enterprises, hazardous chemical storage enterprises and chemical parks.

01 wide detection area

The fixed reflection laser gas telemeter can detect methane at a distance of 1km, and can detect ethylene, acetylene, hydrogen sulfide and other gases at a distance of 200m.

02 preventive monitoring

Different from the passive waiting of the traditional detection mode, it actively monitors the leakage risk points. The response time is only 1 second, which can accurately detect ppm micro leakage. Truly realize the preventive monitoring of gas leakage.

03 convenient installation

The laser transmitting end and receiving end are integrated at one end, and only the reflecting device is installed at the other end, which is convenient to install.

04 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.

05 precise measurement

The leakage gas concentration is quickly obtained by spectral inversion algorithm, and the sensitivity is as high as 1ppm m. Completely eliminate the phenomenon of false and missing reports.

06 "0" maintenance

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

07 long service life

The service life of the product is up to 20 years.

08 detection of gas diversification

Compared with the traditional single gas detection, our company has 6 kinds of Gas detection capability.

Types of gas detection: methane, carbon monoxide, hydrogen sulfide, Alkene, acetylene and ammonia (more gas detection schemes can be provided according to customer needs)

The use of fixed reflection laser gas telemetry instrument can meet the requirements of ensuring the detection quality and reducing the number of on-site inspectors.

In addition to the real-time detection mode, the inspection robot can also be used for intelligent detection of chemical parks.

Tunnel engineering safety protection intelligent robot

Tunnel engineering safety protection intelligent robot is suitable for tunnel combustible gas detection, daily work inspection and other scenes. With 1000m long-distance wireless communication capability, Q235 metal skeleton crawler structure.

It can monitor methane, carbon monoxide, carbon dioxide, oxygen, nitrogen dioxide, hydrogen sulfide and sulfur dioxide, dust and noise in real time.

01 stronger body

The crawler structure with Q235 all metal skeleton is adopted, and it has effective shock absorption and anti-corrosion treatment.

02 faster

The walking speed is more than 1.5 meters per second, and the speed can be adjusted according to the needs of the scene.

03 smoother travel

It has the function of autonomous obstacle avoidance. 200mm obstacle climbing height and 35 ° climbing performance can easily climb all kinds of steep and pothole terrain on the site. 37 ° roll makes the vehicle more stable.

04 strong endurance

Powered by lithium battery, it can work continuously for 12 hours.

05 strong anti-interference ability

It will not be disturbed by humidity, dust, temperature and other gases. It can work for a long time in a high humidity environment and adapt to the changes of temperature environment at the tunnel site.

06 multi gas monitoring

Real time detection of methane, carbon monoxide, carbon dioxide, oxygen, nitrogen dioxide, hydrogen sulfide and sulfur dioxide.

07 safety construction process control

Add dust, noise and other numerical monitoring. Meet the requirements of occupational health and safety standards for tunnel construction environment in code for design of railway tunnel tb10003-201.

08 longer telemetry distance

Support WiFi, 4G and 5g wireless communication, and the remote control distance can reach 1000m.
