Gas safety is closely related to people's lives. It is reported that according to the work requirements of the implementation plan of Guangdong Province for urban gas safety investigation and regulation, and in combination with the situation of the province's urban gas safety investigation and regulation stage and the recent frequent occurrence of gas safety accidents in catering places, Guangdong Province is vigorously promoting the installation of combustible gas alarm devices in catering places.

Article 36 of the new production safety law clearly stipulates that "if the production and operation units of catering and other industries use gas, they shall install combustible gas alarm devices and ensure their normal use."

Based on this, Guangdong Province has vigorously promoted the installation of combustible gas alarm devices in restaurants throughout the province.

By the end of 2022, the catering establishments using gas in Guangdong Province, including all kinds of catering establishments with business nature, catering establishments that use gas but only provide takeout and distribution, and all kinds of internal canteens that provide catering services, will basically achieve the goal of fully installing combustible gas alarm devices, and provide safety protection for the lives and property of the broad masses of people and the gas catering establishments.

The so-called catering places include all kinds of catering places with business nature, catering places that use gas but only provide takeout and distribution, and various internal canteens that provide catering services.

Guangdong is a city integrating trade and information industry development. With a large population, the catering industry is prosperous. At night, the big stalls and snack streets are full of people. However, the current management difficulty is that the scattered restaurants have weak safety awareness of using gas and loose management, which brings safety risks. At present, the most immediate and effective way is to replace civil air defense with technical defense. Use the most advanced technical means to monitor the full coverage of gas involved in urban catering, and rely on people's consciousness to the minimum.

Passive optical fiber laser leakage monitoring system

Hanhai science and technology group and Hefei Institute of Materia Medica of Chinese Academy of sciences have undertaken the industrialization of the national major special scientific research achievement laser absorption spectrum gas detection technology. According to the current situation of gas safety in the catering industry, a complete solution is designed by using the most advanced laser absorption spectrum gas detection technology. It can eliminate the existing safety hazards in catering places! The equipment can realize real-time online, high accuracy, calibration free, high sensitivity and reliable detection.

The passive optical fiber laser leakage monitoring system consists of a monitoring platform, a light sensing terminal and a solenoid valve. The monitoring platform is placed in the monitoring center, the light sensing terminal is placed at the gas and fire use site, and the solenoid valve is placed at the inlet of the gas pipeline. The platform is connected with the light sensing terminal and the solenoid valve by optical fiber to form a gas safety monitoring network. Once the gas leaks, the system will immediately drive the solenoid valve to cut off the gas source to prevent the explosion. When the air of the unit using gas and fire reaches the safety standard, the system will automatically restore the air supply.

01 no power supply is required on site

The system host can be installed several tens of kilometers away, while the monitoring site of gas and fire only needs to install passive light sensing terminals (pure optical equipment, no power supply). The remote monitoring platform is used to realize the real-time online monitoring of combustible gas in the catering gathering area.

02 no calibration required

The passive optical fiber laser leakage monitoring system does not require regular calibration and maintenance, and can ensure its normal use. No false alarm can improve the reliability of gas detection.

03 long service life

Using semiconductor light source and optical glass, no contact measurement, no physical loss, and the service life can reach ten years. Therefore, the service life of passive fiber laser leakage monitoring equipment is 10 times that of traditional detection equipment.

04 more stable

The stability of traditional detection equipment is poor, and it is easy to be impacted and poisoned by high gas leakage concentration; And then detects a failure. Passive fiber laser leakage monitoring equipment does not have this problem. The working performance is more stable.

At the same time, the point type combustible gas detector has obtained the fire protection product certification, which is the only laser gas detection product in the industry that has obtained this certificate.
