[ Focus on Chemical Machinery and Equipment Network ] According to the National* Document No.
116, it is stated that from January 1, 2018, all newly-built chemical plants and storage facilities for hazardous chemicals involving "two important points and one major" must be designed to meet the required safety Instrument SIS system.
For other newly-built chemical installations and hazardous chemical storage facilities safety instrumented systems, from January 1, 2020, relevant functional safety standards and requirements shall be implemented, and safety instrumented systems that meet the requirements shall be designed.

In the production process, whether it is due to the machine itself or the production abnormality caused by the operation of the production personnel, the safety instrumented system can automatically detect it, and then automatically determine whether to stop the current production or adjust the parameters To ensure normal production, safety accidents due to operation or machine abnormalities will be avoided to a large extent.
It is understood that the overall scale of safety instrumented systems will grow rapidly at a compound annual growth rate of 8.
3% in the future.
It is estimated that the market size is expected to reach 474 million U.

The safety instrumented system, referred to as SIS, is mainly the alarm and interlocking part of the factory control system.
It implements alarm action or adjustment or shutdown control on the detection results in the control system.
It is an important part of the factory's automatic control.
The safety instrumented system includes sensors , logic arithmetic units and final execution elements, namely detection units, control units and execution units.
The SIS system can monitor the hazards that appear or latent in the production process, send out warning messages or directly execute predetermined procedures, and immediately enter the operation to prevent accidents and reduce the harm and impact of accidents.

At present, in the life cycle stages of design, installation, operation and maintenance management of safety instrumented systems and related safety protection measures in my country, there are still insufficient hazard and risk analysis, improper design selection, unreasonable redundant fault-tolerant structure, and lack of clear details.
Inspection and testing cycle, preventive maintenance strategy is not well-targeted and other issues, standard safety instrument system management work needs to be strengthened urgently.
As my country's chemical equipment and storage facilities for hazardous chemicals become large-scale, and the level of automation in the production process is gradually improved, it is urgent and necessary to simultaneously strengthen and standardize the management of safety instrumented systems.

In addition, with the continuous development of big data and technology, both production and people's life>By combining with big data, when a problem is found, it can directly connect to the database for data analysis.
Through the analysis, the cause of the problem can be automatically determined, and whether this situation needs to be checked, etc.
, which is more convenient The detection when the machine has a problem reduces the manual analysis steps of the machine's past failures.
As the safety instrumented system develops toward intelligence, not only can the problem be analyzed, but also the cause of each problem can be saved and the steps for how to solve it, which provides a lesson for the same problem in the later period.

In recent years, the importance of production safety in our country has increased, and the government has introduced relevant policies and regulations for petrochemical, chemical, and other dangerous industries.
Driven by policies, the allocation of new facilities and the demand for upgrading and transformation of existing facilities will promote the further popularization of the SIS system and its vigorous development.
