In general, helmets are used to protect the head from external impacts in driving or working and special mission situations. A general construction of such a helmet is composed of a helmet body having a head receiving portion and a windshield which is openably and closably opened and closed on an opened face portion of the helmet body and is composed of a light transmitting body.

Accordingly, when the helmet is worn and an impact is applied to the outside during operation or work, the helmet body cushions the impact to reduce the impact on the head, thereby minimizing the head of the worker. In particular, helmets are used for safety assurance during special missions, and they are used for various purposes such as to prevent the emergence of marine police officers who control illegal fishing, and to prevent injuries during fire fighting and police activities.

In addition, in the case of a helmet used by a marine police, a camera equipped with a camera module in the head portion of the helmet body for securing the image of the illegal fishing control process is used as a helmet used for special mission activities The helmet has been developed and used, and a sports camera, which can be attached and detached between the sportsmen of the general public, is installed on the upper part of the helmet and is used for traveling and shooting sports activities while driving.

Recently, a variety of helmets for the field management of workers have been developed. As one of these helmets, a field work management system using a smart helmet is disclosed in Korean Patent Publication No. 10-2013-0052420.
