& ldquo; This year, the company's business is growing rapidly, and some chemical enterprises will come to our doors on their own initiative. & Xiao Wang is a salesman of a personnel positioning system company. His remarks reflect the increasing importance of safety work in the chemical industry. At the same time, from the side, it shows that the new information security technology is being recognized and accepted by more and more enterprises. Several industry experts recently said that the role of information technology in chemical safety production is becoming more and more prominent. New systems and modules based on new information technology, such as personnel positioning, intelligent inspection, monitoring and warning of major hazards, and information management platform for safe production, have opened up safe production for chemical enterprises. It provides more efficient tools.
& ldquo; last kilometre & rdquo; road is obstructive and difficult
& Safety production is the lifeline of chemical enterprises, without which nothing can be said. & Na Yongliang, general manager of Beijing Sichuang Information System Co., Ltd., who has nearly 30 years'experience in chemical industry, said, & ldquo; In order to ensure the safety of chemical production, China has formulated a series of comprehensive and detailed requirements and regulations, and local governments also arrange regular and irregular safety production inspection and supervision every year. Governor.
Laws and regulations should not be incomplete, and supervision should not be lax. However, for some enterprises, the management has achieved the ceiling, but the situation of safety production in the chemical industry is still grim, and safety accidents are still frequent. The reason is that the implementation of enterprise safety management measures is not in place, safety production & lsquo; last kilometer & rsquo; has not yet been opened. ”
Qian Ganuo, manager of Sales Department of Shanghai Huayi Information Technology Co., Ltd., also mentioned that although enterprise managers attach great importance to safety production, it is very difficult to implement safety production at the grass-roots level of enterprises. For various reasons, the same hidden dangers will appear repeatedly, and employees will ignore and inspect hidden dangers. There are many phenomena, such as inconsistent standards for inspectors, difficulty in closing the whole process of hidden danger rectification and so on. According to Changano, the pain points in safety production of enterprises lie in the difficulties of hidden danger management, dangerous operation management, safety training, on-site management of factories and intuitive device management, which bury many hidden dangers to safety production of enterprises.
& At present, there are still many problems in the safety management of chemical enterprises, and hidden dangers are everywhere. The low level of automation of production equipment, the lack of strict implementation of safety management system, and the lack of safety awareness of personnel have left many hidden dangers to the safety production of enterprises. At the same time, because there are many information islands, poor information communication, unclear boundaries of responsibilities and other human factors within the enterprise, it also greatly affects the improvement of enterprise safety management level, safety in production-lsquo; the last kilometer-rsquo; there are many break-ends. & rdquo; Wu Aibin, chairman of Longkun Intelligence Technology Co., Ltd., said.
New Technology Brings New Solutions
In order to promote the level of safety management and control of enterprises, Jiangsu Emergency Department issued the Basic Requirements for the Construction of Information Management Platform for Safety Production of Chemical Enterprises in Jiangsu Province (Trial Implementation) on August 13. For the first time, it put forward specific requirements for the use of information management platform for safety management, i.e. ldquo. Principles for completing the design and development of the overall framework are as follows: first and second level major hazard chemical enterprises should complete the construction of major hazard monitoring and early warning system, real-name entry and exit management function and risk assessment and commitment announcement function by the end of October 2019; by the end of 2019, major hazard monitoring and early warning system and on-the-job production personnel should be completed. Bit management system construction and risk assessment and commitment announcement function construction; by the end of 2020, according to the "Basic Requirements" to complete the construction of production safety information management platform. ”
Industry experts believe that this regulation will play an important role in getting through the production safety & ldquo; the last kilometer & rdquo.
& It is of great significance for chemical enterprises to solve the problems of safety management & lsquo; last kilometer & rsquo. & In the era of industrial internet, the application of advanced information technologies such as three-dimensional, Internet of Things, mobile internet, big data and artificial intelligence in the chemical industry undoubtedly provides chemical enterprises with new, efficient and reliable technical means to help enterprises achieve scientific and comprehensive hidden danger investigation, but also Safety management can be intellectualized, informationized and mobile. At present, Langkun is actively carrying out chemical production safety management information work, and has a mature five-in-one solution, including five subsystems: major hazard monitoring and early warning, safety risk zoning information, personnel on-the-job management, safety production management and equipment assets management, which can help chemical enterprises to achieve. All-round safety control. ”
Wei Chuan, general manager of Zhejiang Central Control Technology Co., Ltd. Production Safety Solution Center, believes that: & ldquo; The root cause of danger in chemical enterprises lies in unsafe behavior of people, unsafe state of things, management defects and environmental factors. How to eliminate these risk factors, information technology provides a new way. In January 2018, the Office of the Security Committee of the State Council issued the Opinions on the Implementation of Guidelines for the Work of Containing Serious and Extraordinary Accidents and the Construction of a Dual Prevention Mechanism. It was mentioned that the application of intelligent and information technology should be strengthened to realize remote monitoring, automatic control, automatic early warning and emergency avoidance of major hazards. It is reported that many intelligent and information-based safety management and control technologies have been applied in chemical enterprises and achieved good results. Focusing on the five core concerns of human, machine, material, law and environment, CNC has developed a set of solutions, including complete and systematic solutions, as well as independent sub-solutions for risk assessment, risk perception and collaborative management and control.
& State-based predictive maintenance management of equipment is an effective means to prevent major accidents. & rdquo; PetroChina UniversityLiu Wei, Deputy Engineer of information center of Qinghua Petrochemical Company, said, & ldquo; Predictive maintenance is to transfer the maintenance and management of equipment from afterwards to beforehand. Through on-line monitoring analysis, intelligent diagnosis and reliability analysis of large petrochemical units, pumps, power equipment, etc., hidden faults can be found in time to avoid machine damage. The occurrence of human death accidents. ”
It is reported that dozens of petrochemical and chemical enterprises in China have applied on-line monitoring and analysis, intelligent diagnosis and predictive maintenance technology, and the fault diagnosis rate has reached 90%. For example, PetroChina, CNOOC and other enterprises have built 10 remote diagnostic centers for industrial Internet mobile equipment, which play an important role in preventing accidents.
5G technology will make a big difference
This year is the first year of deployment and application of 5G technology. The application of 5G technology in chemical industry has also begun. The scene of 5G response has outlined the embryonic form. The role of 5G technology in improving the level of chemical safety production can not be underestimated. Industry professionals believe that 5G technology will play an important role in the process of building intelligent safety barrier for chemical enterprises.
There are many problems in chemical plant areas, such as large patrol workload, many blind areas, inadequate safety facilities and supervision means, weak ability of automatic identification and disposal, which is also an important reason for the weak safety guarantee ability. At the same time, data acquisition and control system of chemical production needs large bandwidth, low delay and high reliable communication technology as support, and 5G just meets this demand.
The application of 5G technology is in the forefront of the industry. Dai Yuanxuan, director of BASF Greater China Digital Intelligent Manufacturing Team, said that 5G technology has begun to pilot in Shanghai, including electronic work tickets, especially the management of high-risk work tickets. 5G technology has many advantages. On the job site, 5 to 10 cameras can be supported by 5G technology, and the operation of the staff can be video broadcast live, monitoring the job site and finding problems can be dealt with in time. 5G network can also support personnel positioning and the application of AGV (automatic guided transport vehicle) in complex environment in chemical plant area.
It is understood that Zhejiang Xin'an Chemical Group Co., Ltd. has also taken the lead in making breakthroughs in the application of 5G technology. Zhang Jian, deputy general manager of the company's informatization department, said that at the beginning of this year Xin'an Chemical Industry Co., Ltd. established a joint innovation cluster team with several enterprises, conducted field research and technical exchanges for nearly three months, and intellectualized identification, monitoring, guidance, early warning and rescue in terminal information collection, wireless transmission, safety and explosion protection, etc. On the other hand, it has formed the technical solutions of & ldquo; 5G + AI & rdquo; and successfully launched the 5G industrial data acquisition and control system, which not only adds new vitality to intelligent manufacturing, but also builds up & ldquo; intelligent defense line & rdquo;.
Zhejiang Mobile and China Control Group adopt ZTE 5G end-to-end solution, innovatively integrate multiple data acquisition terminals of Xin'an Chemical Park into 5G network through PLC, and realize real-time UI monitoring of control platform. Once abnormal data is found, alarm and start reverse control system immediately. The average end-to-end delay of the system is 20 ms, which meets the control requirements of chemical production.
