Abstract
Description
Technical Field
[0001] The present invention belongs to the field of monitoring and early warning technology, and in particular relates to a multi-source sensing early warning method and system based on dangerous scenarios in a production environment. Background Art
[0002] The chemical production process is full of potential risks, including the leakage of flammable and explosive gases, abnormalities of high-temperature and high-pressure equipment, etc. Ensuring production safety is the primary task of the enterprise. With the expansion of the production scale and the increase in process complexity of chemical enterprises, the safety risks in the production process are increasing. Therefore, how to effectively monitor and warn of these dangerous situations is crucial to protecting the lives of employees and the continuity of production.
[0003] At present, most monitoring and early warning systems usually rely on specific types of sensors and equipment to identify potential hazards, but often only focus on a specific risk scenario, which limits their ability to comprehensively and timely detect various potential hazards in chemical production. When multiple risk factors exist at the same time, the existing system may not be able to provide accurate alarms, which will affect the overall risk identification and response, leaving safety hazards. In addition, many traditional monitoring and early warning systems rely on rules and thresholds for judgment and lack intelligent analysis capabilities, resulting in low accuracy in identifying dangerous scenes in the production environment, prone to false alarms and missed alarms, increasing the workload of managers and even causing safety accidents. More importantly, traditional early warning systems usually have only a single warning method, which is difficult to effectively attract the attention of staff in an emergency, which may result in a failure to respond in time when danger occurs.
[0004] Therefore, it is urgent to develop an intelligent and integrated multi-source sensing warning system to detect dangerous scenes in the production environment and issue timely warnings. Summary of the invention
