Welding safety monitoring system based on multi-sensor coordination

Abstract

The invention discloses a welding safety monitoring system based on multi-sensor cooperation. The welding safety monitoring system comprises a welding personnel safety helmet, a Zigbee on-chip system integrated with a single chip microcomputer kernel, a photosensitive sensor and interface circuit, a reflex infrared electric sensor and interface circuit, a three-axis acceleration sensor, a reflector plate, a first shading plate, second reflector plate protection spectacles, a handheld mask and a Zigbee module. The welding safety monitoring system is reasonable in structure and capable of judging whether employees use the welding handheld mask or the protection spectacles, wear the safety helmet or tumble or not accurately and timely.

Description

[0001] This application is a divisional application with application number: 201410650747.1, application date: 2014.11.17, and name "Remote Monitoring and Alarm System for Ship Welding Personnel Based on Multi-sensor Information Fusion". technical field [0002] 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 [0003] 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. [0004] The welding of ships in my country is mostly manual welding....

Problems solved by technology

[0005] 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. In the occasion where many people are welding at the same time, People who are not engaged in welding operations are also vulnerable to peripheral 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.
