Sichuan Chengdu Chemical Production Enables Earthquake Warning to Control DCS System

[China Instrument Network Instrument R&D] On December 14th, the DCS system (Distributed Control System) of Chengdu Shangyu Coatings Co., Ltd. (abbreviated as Shangyu Coating) started the earthquake warning, which marked the first time that China Chemical's automatic production line had enabled earthquake warning.

It is understood that the Chinese chemical product line has gradually been automated, which makes it more convenient to cope with earthquake disasters while improving production efficiency. The ICL earthquake warning system independently researched and developed by the Chengdu Institute of High and New Technology for Disaster Reduction (referred to as the Disaster Reduction Institute) was connected to the DCS system of Shangyu Coatings. When an earthquake with an intensity threshold is reached, the earthquake warning system will trigger the DCS system to automatically suspend the corresponding equipment in the paint production line, so that the valve and other devices are in a safe state, reducing the danger of hazardous chemicals caused by the earthquake.

Chen Kaige, the general manager of Shangyu Coatings, told reporters that after the earthquake warning is activated, the DCS system will automatically suspend the production equipment through the earthquake warning system, which is beneficial to the production of the company and the life safety of employees, and will help reduce secondary disasters caused by improperly disposed and improperly produced production. .

Chen Kaige, general manager of Chengdu Shangyu Coating Co., Ltd., said: “Because it was the time when the earthquake and the disaster came, the plant’s equipment was first-in-first-out (product) because it was a hazardous chemical plant. Way, then it will cause a lot of loss or waste, then after an applied earthquake early warning system shuts down which part first and then which part is closed, which part will he turn out to be a perfect process, then for the factory and for safety The loss of the factory will be reduced to a lower level, and then there will be tens of seconds to a minute of escape time for the personnel, and there will be greater protection for the life support of the personnel."

The general manager of the Chengdu division of Zhejiang Zhonghua Technology Co., Ltd., which provides the DCS system for Shangyu Coatings, also stated that due to the particularity of the hazardous chemical industry and the complexity of the DCS system, the dangerous enterprise needs to develop individuality in accordance with its own characteristics. The earthquake pre-warning emergency plan realizes “the off of the customs, the opening of the opening”.

This progress was also praised by Pan Peng, general manager of Chengdu Zhonghua Technology Co., Ltd. Chengdu Branch. “It should be said that this is also the first time China’s first earthquake early warning system received the central control system. Actively defending against earthquake disasters should be representative for our plant installations, especially those used by chemical companies, to actively defend against earthquakes. This kind of natural disaster can also ensure the safety and security of our personal safety. Equipment safety: It should be said that the application is very broad, except in our chemical companies, especially in the power industry, especially nuclear power applications, it should be said that all industrial enterprises can be widely used, including smart buildings, etc. have a wide range of applications space."

Dr. Wang Wei, director of the National Thousand Talents Program and director of the Chengdu High-Tech Disaster Reduction Research Institute, told reporters that the chemical production line has enabled earthquake warning and can automatically shut down the production line before the earthquake reaches the factory, leaving the plant in a safe state and avoiding toxic substances. The emissions also reduce personnel injuries or reduce secondary disasters.

"So obviously after the earthquake warning is started as the first chemical production line, we should be able to drive more chemical production lines or say that all chemical production lines can enable earthquake warning to greatly reduce secondary disasters. Our country's dangerous chemical production area is significant. The source of danger needs more protection. Then the earthquake does not know when it will happen. So we need such an active defense technology system to be able to guarantee the safety of chemical plants and reduce the number of casualties in secondary disasters. After this work is done, Earthquake early warning can be enabled in more major projects and lifeline projects. Then, the use of earthquake early warning in densely populated locations can also be used to start the entire community's emergency response using the earthquake early warning during the time of the earthquake.” Chengdu High-tech Disaster Reduction Research The director of the institute explained.

Up to now, the ICL earthquake warning technology independently developed by the Institute for Disaster Reduction has built the world's largest earthquake warning network extending to 31 provinces (municipalities, autonomous regions), covering 2.2 million square kilometers, and covering 90% of the population in China's seismic regions. Since 2011, it has gradually passed five consecutive years of safety service for people, schools, communities, chemical industry, subways, high-speed railways, national defense, national early-warning information release centers, and national disaster reduction centers through mobile phones, radio and television, government affairs microblog, and dedicated receiving terminals. Major projects and other areas, and continuous warning of Lushan 7 and Ludian 6.5 earthquake and other 31 destructive earthquakes. At the same time, the earthquake warning technology has served Nepal.
