Abstract

The invention discloses a method for monitoring the production safety of manganese-rich slag based on information fusion. The system adopted includes an information fusion computer, a video analysis computer, sound and light alarm equipment, an information fusion display, a video display and a plurality of manganese-rich slag production safety monitoring methods. Monitoring node: Manganese-rich slag production safety monitoring node includes Ethernet I / O acquisition module, network camera, combustible gas detector, dust concentration sensor and fire detector. The method of the present invention includes steps: 1. data collection and transmission, 2. constructing evidence body and determining the basic credibility distribution of each evidence body, 3. determining the weight coefficient of each evidence body, 4. judging the monitoring area Z k Whether there is a conflict among the evidence bodies in the test box, 5. Judgment of the production safety status of the evidence body conflict situation, 6. The production safety status judgment of the evidence body non-conflict situation, 7. Video image analysis auxiliary judgment, 8. Judgment result output. The design of the invention is novel and reasonable, and the monitoring effect is intuitive and reliable.

Description

technical field [0001] The invention belongs to the technical field of manganese-rich slag production safety monitoring, and in particular relates to a 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 perfor...

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.
