The invention discloses a system and a method for manganese-rich slag production safety monitoring on basis of information fusion. The system comprises an information fusion computer, a video analysis computer, audible and visual alarm equipment, an information fusion display, a video display and a plurality of manganese-rich slag production safety monitoring nodes; each manganese-rich slag production safety monitoring node comprises an Ethernet I / O (input / output) acquisition module, a webcam, a inflammable gas detector, a dust concentration sensor and a fire detector. The method includes the steps: firstly, acquiring and transmitting data; secondly, setting evidence bodies and determining basic probability assignment of each evidence body; thirdly, determining weight coefficient of each evidence body; fourthly, judging whether evidence bodies in a monitoring area Zk are in conflict or not; fifthly, judging production safety states under the condition that the evidence bodies are in conflict; sixthly, judging production safety states under the condition that the evidence bodies are not in conflict; seventhly, analyzing video images for judgment assistance; eighthly, outputting a judgment result. The system and the method for manganese-rich slag production safety monitoring on basis of information fusion have the advantages of novel and reasonable design and directness and reliability of monitoring effects.

Description

technical field [0001] The invention belongs to the technical field of manganese-rich slag production safety monitoring, in particular to a system and method for manganese-rich slag production safety monitoring based on information fusion. Background technique [0002] In the production process of manganese-rich slag, due to the influence of the production process, the production site has many equipment, many pipelines, and a large area. The impact on safe production includes many potential gas leakage points, many dust sources, scattered hazards, The possibility of fire and explosion accidents is high. At the same time, the harsh production site environment seriously affects the reliability and stability of the monitoring system's safety status monitoring. [0003] The impact of various risk factors on the safety monitoring system is mutual and multifaceted. In the safety monitoring system for the production of manganese-rich slag, the safety monitoring system that perform...

AI Technical Summary

Problems solved by technology

Due to the uncertainty and variability of fire occurrence, as well as the impact of harsh production environment, fire detectors are inevitably affected by factors such as dust in the air of manganese-rich slag production, thermal radiation, etc., resulting in false alarms and missed alarms, which are difficult to meet Early detection of fire

[0007] Dust monitoring: In the production of manganese-rich slag, due to the large number of dust sources, the site dust pollution is serious

However, because the harm caused by dust pollution is often indirect, the harm it brings is often ignored by people, thus burying potential safety hazards.

The harm caused by dust pollution is multifaceted, such as equipment leakage, short circuit, combustible dust can also cause fire, explosion and other safety accidents

In addition, dust has a serious impact on safety monitoring sensors. The accumulation and dispersion of dust will cause false alarms and false alarms of fire detectors and combustible gas detectors, or even fail.

[0008] In summary, the safety monitoring system that monitors a single risk factor in the production of manganese-rich slag does not consider the multifaceted nature of safety hazards and the impact of risk factors on safety monitoring

Therefore, it is inevitable that it will be interfered by dangerous factors, which will affect the reliability and accuracy of safety monitoring.
