Method for constructing safety early warning system

Abstract

The invention discloses a method for constructing a safety early warning system, which comprises the steps of early warning index monitoring, early warning, early warning comprehensive analysis, alarming and deviation correcting, and is characterized in that early warning comprises single-index early warning, subsystem early warning and system early warning. The deviation correcting step is connected with the early warning index monitoring step to perform data feedback adjustment. The safety early warning system disclosed by the invention can acquire safety early warning degree information ofthe whole chemical industry production system, achieves an effect of understanding and mastering system safety conditions in the production process, can acquire safety early warning for subsystems, and acquires safety early warning for the whole chemical industry production system on the basis of safety early warning for the subsystems. The safety early warning is sent to the enterprise safety management and technical personnel through an internal communication network of an enterprise to serve as a reference for taking corresponding measures and starting a corresponding level of emergency plan. The method performs analysis, evaluation and early warning on the chemical production process, can effectively avoid occurrence of safety accidents in the chemical production process and has very high practicability and operability.

Description

technical field [0001] The invention belongs to the technical field of chemical production safety early warning, and in particular relates to a construction method of a safety early warning system. Background technique [0002] Judging from the development status of my country's chemical industry, with the gradual expansion of production scale, especially in the process of rapid expansion and development, safety management is often neglected, and many problems have been exposed due to inadequate management. Many problems have occurred that should not have happened. accidents, and even many painful lessons, so it is necessary to design an early warning system to prevent safety accidents. In the current chemical production process, a single indicator early warning is often used. Because of its intuitiveness and immediacy, the single indicator early warning can directly obtain the early warning degree. And it can be corrected in time, but for the safety early warning system in th...

[0002] Judging from the development status of my country's chemical industry, with the gradual expansion of production scale, especially in the process of rapid expansion and development, safety management is often neglected, and many problems have been exposed due to inadequate management. Many problems have occurred that should not have happened. accidents, and even many painful lessons, so it is necessary to design an early warning system to prevent safety accidents. In the current chemical production process, a single indicator early warning is often used. Because of its intuitiveness and immediacy, the single indicator early warning can directly obtain the early warning degree. And can be corrected in time, but for the safety early warning system in the production process, it is far from enough

[0003] The existing technology, such as the patent document of Chinese invention authorization, the authorized announcement number CN 103775129 B, a method for early warning of coal mine hazard sources, belongs to the early warning method of coal mines, and the identification of hazard sources and the risk level of hazard sources are carried out through the coal mine hazard source early warning system. Evaluation and monitoring of hazard sources; on the computer terminal in the local area network, the coal mine dispatching room and the large-screen terminal at the wellhead, the electronic mine map is used as the background to dynamically broadcast the hazard information of different locations and levels that have not been reviewed or failed the review, and different early warnings Levels of hazards are represented by different colors; for places that have an important impact on coal mine safety production, a wireless sensor network is set up to monitor the information of hazards that occur at the location in real time. Manual entry, the specific information of hazard sources cannot be displayed in time on the terminal equipment of the dispatching room or the large screen at the wellhead. Relevant functional departments arrange rectification to ensure safe production in coal mines. Carry out advanced and timely pre-control and management, but the effect of connecting and mastering the system security status of the entire production process is not ideal
