Petrochemical industry solution

Tank / factory / mobile tank car / oil and gas pipeline

Summary

With the development of China's petroleum industry and the increase of crude oil and refined oil reserves, there are more and more large domestic oil depots and oil tanks. Large scale oil tanks and gas storage tanks in these petrochemical industries are often concentrated in a large number of locations. In case of accidents, huge losses of personnel and property will be caused. Temperature, as an important parameter reflecting the safety of tank farm, is directly related to the safety of life and property. Materials such as heavy metals, compounds, fuel and steam in the air around the oil tank area are not conducive to the work of conventional electrical sensors and instruments. Due to the passive optical fiber sensing system, the unique characteristics of the monitoring site without any electronic equipment, the intrinsic safety of flammable and explosive situations, rapid response and resistance to corrosive liquids, the FBG temperature measurement system is especially suitable for the flammable and explosive petrochemical industry.

The system consists of four parts: optical fiber sensor, transmission optical fiber cable, FBG Intelligent demodulator and computer. The fiber Bragg grating temperature sensor is installed on the surface of the measured point to collect the temperature signal; the fiber grating analyzer and the computer are placed in the control room; the signal is transmitted between the measured point and the control room, and the fiber grating demodulator transmits the data to the computer through the Ethernet, and the computer system implements the number. According to processing, fault diagnosis, alarm and control.

System structure

Through the fiber Bragg grating temperature sensor, which is laid in the defense area (such as tunnels, oil tanks, etc.), the temperature of the measured region is fed back to the demodulator in real time through the light signal. The temperature data is calculated. The measuring software completes the fire warning according to the temperature information. The analyzer can complete linkage control with other fire fighting devices through data interface, and upload temperature and alarm information to control center.

System characteristics

1. all optical network communication, intrinsic safety, explosion-proof, flame retardant, corrosion resistant, anti electromagnetic interference;

2. only optical fiber and fiber Bragg grating sensors are installed in the field, without electronic equipment, and the system is safe and reliable.

3., the system can set alarm temperature arbitrarily, and is convenient and flexible.

4. the system software can directly display the specific location and name of the tested area, and analyze the fault trend and locate it accurately.

5. real-time online monitoring, preservation of data and abnormal information records, as a basis for long-term operation experience accumulation and accident analysis;

6., it can connect to LAN or other network system. Any computer in LAN can access the system and share information.

Optical fiber on-line monitoring system for dangerous goods vehicle

Monitoring demand background of dangerous goods vehicles

China has entered the rapid development stage of the heavy chemical industry. It is the fastest growing area of world oil and chemical industry. The consumption of major oil and chemical products in China will reach 1/3 of the global total consumption.

In recent years, dangerous chemical transportation accidents have occurred frequently, resulting in serious consequences. The safety situation of hazardous chemicals highway transportation is very severe. In order to reduce casualties and property losses caused by accidents and improve transport safety, it is urgent to develop state monitoring system for highway transportation of hazardous chemicals.

The design aims at serving the safety management of dangerous chemicals transportation vehicles, establishes a perfect operation supervision information system, accurately grasps the data information such as the temperature, location and leakage of the goods during the operation of dangerous chemicals, reports the monitoring information and data to the service platform in real time, and analyzes the problems in the transportation process of the dangerous chemicals. We should realize real-time supervision, dynamic management and scientific decision-making of dangerous chemicals transportation vehicles, and improve the comprehensive management level of vehicle transportation process.

Conform to the concept of the development of science and technology in the times, big data and Internet of things. This system has the characteristics of complete functions, simple operation and intelligent full coverage. It fully meets the needs of on-line monitoring and intelligent management of dangerous goods vehicles. The system combines optical sensing technology, electronic demodulation technology, Internet of things communication technology, software integration technology, large data processing technology, GIS geographic information technology, mobile APP technology and other multi-source data fusion technology, for the first set of domestic independent property rights with advanced international level of high-tech intelligent products, completely done The function is complete and stable, the data is encrypted and the interface can be open and integrated with the outside world. It can be customized according to the needs of the user, realize small order and develop a comprehensive monitoring system for special mobile dangerous chemicals. The online monitoring system for mobile dangerous goods vehicles is a unique invention technology of our company. It contains 3 invention patents and 4 design patents.
