As a large-scale refinery and chemical company, CNPC’s plant safety management work has always been concerned by the society. Due to the large scale of the factory, the large number of operators, the large-scale and dense production equipment, the complex production process, and the tightly coupled production process, it belongs to a high-temperature, high-pressure, flammable, explosive, and toxic dangerous industry. How to ensure the safety of personnel? Realizing the monitoring and management of plant materials has become a long-term exploration and adherence to CNPC. During the 12th Five-Year Plan, China National Petroleum Corporation listed the scalable IoT system platform as one of the three key projects in the “Twelfth Five-Year Plan” informatization construction, and included the application of the Internet of Refining Projects in the “Twelfth Five-Year Plan” information technology master plan. , Hope that through the application of various Internet of Things technology, real-time acquisition of equipment, installations, tank farms, warehousing, energy consumption, personnel and vehicles and other field data information, to achieve effective interconnection of things and things, things and people, people and people Interaction provides technical support for enterprise fine management and intelligent management.
Aerospace Huatuo began to penetrate into the petroleum and petrochemical industry in 2015, focusing on the application research and product development of IoT solutions in the fields of personnel positioning, warehouse management, and material management and control. In 2016, it successfully won the bid for the “personnel positioning” pilot application of China Petroleum Refining Internet of Things. project. In the same year, China Aerospace Science and Technology Corporation and China National Petroleum Corporation signed a strategic cooperation agreement, and Aerospace Huatuo signed a landing strategic cooperation agreement with the China National Petroleum Planning Institute to develop in-depth refining Internet-positioning and safety management systems. cooperate. Up to now, the personnel positioning terminal products of Aerospace Huatuo have been widely used in 20 refining and chemical branches of PetroChina, covering nearly 20,000 people on site.
Looking back at the beginning of the cooperation, in order to choose the most suitable positioning solution for the use environment of PetroChina’s refinery, the Aerospace Huatuo team conducted a large number of investigations and tests on the positioning environment of the refinery. The factory conducts on-site surveys and tests, and chooses to organize a special technical test in a chemical fiber factory in Jiangsu, which has a similar environment to the refinery, and finally tailors a set of personnel positioning solutions suitable for the operating environment of the refinery.
1. The integration of diversified technologies to achieve accurate and full coverage indoors and outdoors, using pseudo-range differential technology to counter interference;
Adopt Beidou + GPS dual-mode satellite positioning technology;
Adopt targeted anti-multipath technology;
Inertial navigation positioning technology is used to supplement the positioning of the occluded area;
Use 2.45GHz active RFID positioning technology to supplement the satellite signal shielding area.
2. Smart wearable terminal, control personnel status anytime and anywhere
Personnel positioning, abnormal posture perception, historical trajectory query, one-key call for help, cross-zone alarm, 4G full Netcom, log management, remote maintenance, equipment identification
3. A number of patented technologies and software, the system is stable and more reliable
(Partial display)
4. Link the above and below, realize on-site management and control and data feedback
Improve the automatic collection rate of field data;
Improve the safety management level of corporate assets and personnel;
Improve on-site operation and operation and maintenance technical capabilities;
Realize the real-time transmission of data;
Realize centralized management and control of information.
This solution helps the PetroChina Refinery Plant to achieve more standardized, collaborative, scientific and intelligent on-site operations, and personnel safety monitoring and management have become more proactive, timely and accurate, which has greatly improved the level of refined management of the enterprise and successfully built pre-prevention prevention , The security prevention mechanism of early detection during the incident and traceability after the incident has become one of the representative projects of the Internet of Refining.
In the future, PetroChina Planning Institute and Aerospace Huatuo will re-plan cooperation, combining the software platform advantages and resource advantages of PetroChina Planning Institute, as well as Aerospace Huatuo’s own technical advantages and product customization advantages, and focus on personnel safety in the petroleum and petrochemical industry. Each expresses its own strengths in the fields of positioning, personnel intelligent inspection, and intelligent storage, and launches more extensive and in-depth cooperation and promotion of information applications, and jointly promotes the further development of China’s oil and gas industry and the Internet of Things industry.
