Intelligent safety helmet

Abstract

The invention discloses an intelligent safety helmet, and belongs to the field of safety helmets. The intelligent safety helmet is characterized in that when a constructor wears a safety helmet set toconstruct on an underground construction site, a control terminal sends the corresponding voice information to the safety helmet group worn by the constructor at regular time through a fixed relay terminal and a portable fixed terminal, and the information comprises the safety warning words, the engineering introduction, the quality standards, the process key points, the operation step voice information and the like; the signal connection safety of the construction personnel in the underground construction site is ensured through the portable fixed terminal for relaying, so that the constructor is not easy to lose communication with the control terminal, and the production safety accidents are not easy to cause. When an accident occurs on the underground construction site and the construction personnel and the control terminal are disconnected, the search and rescue personnel can quickly position the construction personnel through the portable fixed terminal finally arranged by the construction personnel, so that the search and rescue time is greatly shortened, the search and rescue efficiency is improved, and the survival probability of the construction personnel is improved.

Description

technical field [0001] The present invention relates to the field of safety helmets, more specifically, to intelligent safety helmets. Background technique [0002] The safety helmet is a protective product to prevent impact objects from hurting the head. It is composed of a cap shell, a cap lining, a lower chin strap and a rear hoop. First, the impact force is decomposed to the entire area of ​​the skull, and then most of the impact force is absorbed by using the elastic deformation, plastic deformation and allowable structural damage of the buffer structure of each part of the helmet, so that the final impact force on the head of the person is reduced to Below 4900N, so as to protect the head of the operator, the shell material of the helmet plays an important role in the overall impact resistance of the helmet. [0003] Hard hats usually appear on various construction sites. For some underground construction sites, the hard hats worn by construction workers are usually m...

AI Technical Summary

Problems solved by technology

[0004] Subway tunnels and urban sewers are the two most common underground construction sites. The underground construction environment is very complicated, and the existing network signals are difficult to completely cover the underground construction site. Once construction personnel have an accident on the underground construction site, the search and rescue work will be It is extremely difficult to deploy. For construction workers who encounter accidents underground, time is life. The later the construction workers are positioned and rescued, the more life safety of the construction workers will be in danger.
