He looked at the development of chemical technology in the past ten years and praised China's prosperity and strength in the prosperous age. It is more lively and exciting with everyone's participation. [Ten Years of Development of Chemical Equipment] Continue to update the summary post. Welcome to participate in the discussion https://bbs.hcbbs.com/thread-3576046-1-1.html Prevention first, life first -------------------------------------------------- After a year of technical research and R&D, the 5G explosion-proof private network was officially launched in Tianjin Petrochemical Company. “We are the first company in the country to use the advanced technology of 5G explosion-proof remote units to build a 5G explosion-proof private network. After the implementation of the private network, the signal coverage doubled, solving the signal shielding problem caused by the large number of devices, metal tank areas and pipeline corridors in the petrochemical industry. ”Tianjin Petrochemical Information Management Center * Gao Wenqing, expert and manager of the Information Archives Management Center, introduced. In the past two years, Tianjin Petrochemical has built 27 5G macro base stations and 30 sets of 5G explosion-proof micro base stations in the factory area, which strongly supports the 5G intelligent transformation of petrochemical equipment. ； Through the large-scale application of 5G industrial scenarios, the construction of 5G fully connected factories has achieved intelligent safety management and control, intelligent production monitoring, intelligent equipment management, automatic environmental protection monitoring, etc., enabling quality and efficiency improvement, transformation and upgrading.
Electronic work tickets eliminate blind spots in safety management In order to strengthen on-site safety management, Tianjin Petrochemical has implemented an electronic work ticket system throughout the company. Compared with traditional hand-signed paper work tickets, electronic work tickets based on "5G+ explosion-proof handheld terminals" are fast to operate, and intelligent safety management promotes the further implementation of safety responsibilities at all levels. “In order to ensure that safety responsibilities are implemented in place, the company requires relevant personnel to go to the site to sign tickets. Due to the high-precision positioning of 5G and Beidou, tickets cannot be signed beyond 1 meter away from the working area. ”said Wang Junsheng, deputy manager of the Tianjin Nangang Ethylene Project Management Department Branch One. Electronic work tickets are a microcosm of Tianjin Petrochemical's efforts to create smart construction sites. As the construction of the Tianjin Nangang ethylene project progresses, Tianjin Petrochemical has created a "trinity" closed-loop "intelligent safety" precise management and control model for on-site operations, personnel and the environment based on 5G and Beidou, facial recognition, high-precision maps and other technologies, strictly controls contractor access, and eliminates blind spots in on-site operation safety management.
Extensive “machine generation” to improve work efficiency “Since last year, we have tried to use multi-dimensional sensing robots for intelligent inspection. ”Hu Guangliang, deputy director of the United Ninth Workshop of Tianjin Petrochemical Refining Department, introduced. They placed the inspection robot in the workshop next to the gas separation device and set the inspection time, route and frequency. The robot starts in the workshop on time, "looks, hears and asks" the device along the prescribed route, uses infrared imaging and sound for monitoring, uploads on-site data in real time through 5G, automatically compares it with indoor distributed control system (DCS) instrument data, and detects abnormalities in a timely manner based on the size of the deviation. “Multi-dimensional sensing robots solve problems such as low manual efficiency, high labor intensity, and few sensing methods, and move the safety management frontier forward. At present, we have increased the frequency of robot inspections during weak periods to build a strong line of defense for safe production. ”Hu Guangliang said. In recent years, Tianjin Petrochemical has extensively carried out "machine replacement" pilots. Relying on 5G, visual navigation, adaptive technology, etc., it has implemented application scenarios such as drone intelligent inspection of long-distance oil pipelines and inter-plant pipeline corridors, smart warehousing, intelligent testing, and water quality testing machine replacement. These projects have improved the level of production intelligence, met 24-hour continuous production requirements, and improved work efficiency.
Gas "clairvoyance" helps clean production In the first half of this year, Tianjin Petrochemical installed more than 10 gas dynamic leakage monitors in key detection areas such as pipeline corridors and frames in the refinery unit area. “These instruments, like surveillance cameras, can use laser rays to penetrate gas leaks within 200 meters and accurately identify gas micro-leakage. ”Wang Yuncheng, a mobile equipment management officer at the Tianjin Petrochemical Equipment Department, said that the information is sent back to the external operator through 5G, and the external operator handles it accordingly according to the alarm situation. They use 5G to collect comprehensive and real-time environmental monitoring data, install "5G + laser, infrared technology" gas leakage equipment, draw environmental monitoring maps, strengthen real-time dynamic monitoring and management, and achieve source carbon reduction and clean production. The drawing of this environmental monitoring map is the first in the petrochemical industry. Tianjin Petrochemical has also established a remote monitoring center for key units. Through the full coverage application of "5G+ intelligent electromechanical instrument management platform, pump group status monitoring platform" and "5G+ edge computing (MEC)", it has realized online monitoring, fault warning, intelligent diagnosis and technical online analysis of key units and key pumps to protect safe and environmentally friendly production.
Haha, this is something that should be learned.
It's a great big project, but I don't want to follow it.
