Remote monitoring and alarm system for ship welding personnel based on multi-sensor information fusion

Abstract

The invention discloses a remote monitor and alarm system for a ship welder based on multi-sensor information integration. The remote monitor and alarm system comprises a welder' hamlet, a Zgibee on-chip system integrated with single-chip kernels, a photosensitive sensor and an interface circuit, a reflection type infrared photoelectric sensor and an interface circuit, a three-axis acceleration sensor, a reflecting plate, a first glare shield, second glare-shade goggles, a handheld mask and a Zigbee module. The remote monitor and alarm system has a rational structure and can be used for immediately and accurately judging whether operators use handheld masks or goggles for welding, wear hamlets or fall down.

Description

technical field [0001] The invention relates to a monitoring system, which is a remote monitoring and alarm system for ship welding personnel based on multi-sensor information fusion. Background technique [0002] The shipbuilding industry is a labor and technology-intensive industry. In hull construction, welding man-hours account for about 30% to 40% of the total man-hours of hull construction, and welding costs account for 30% to 50% of the total cost of hull construction. The welding workload of ships is very large. The butt weld seam of 10,000-ton oil tanker is about 20KM; the butt weld seam of 100,000-ton oil tanker is about 50KM; The weld seam is about 30KM long. [0003] The welding of ships in my country is mostly manual welding. In 2012, scholars from Peking University and other institutions (Xu Yan, Gong Manman, Wang Jiao et al. Investigation on the current situation of the harm of electric welding ultraviolet radiation to workers and protective measures[J]. Jour...

Problems solved by technology

[0004] Welder electro-optic ophthalmia caused by welding arc is listed as the second largest occupational disease after pneumoconiosis. The risk of not wearing a protective mask is 1.8 times that of wearing a protective mask, and in the occasion where many people are welding at the same time, People who are not engaged in welding operations are also vulnerable to damage from surrounding arc radiation

In shipbuilding and repairing companies, welding without goggles or welding masks frequently occurs. Arc light and splashes cause visual damage, skin tissue damage and even skin cancer, which seriously affects health and work efficiency.
