Description

Real-time information sharing at the facility investigation site

The present invention relates to a safety helmet for real-time information sharing at a facility survey site, and more specifically, a helmet for sharing information at a facility survey site real-time information sharing in real-time at a facility survey site so that a camera unit and a headset for communication of the condition and communication of the facility are mounted on the helmet so that the facility situation can be delivered to the manager is about

BACKGROUND ART As we enter modern society, various types of emergency situations such as fire, collapse, and harmful gas leakage occur in public places, work and construction sites, and the like.

In order to minimize the damage that may be caused by such an emergency situation, it is necessary to detect the emergency situation early, and it is necessary to clearly understand the degree of the related emergency situation to be able to take an optimal response. It will be possible to minimize damage due to emergency situations.

Conventionally, for example, various closed circuit cameras installed in public facilities, surveillance cameras installed on highways, etc. are operated for this purpose, but since they are operated locally in a certain building or in a certain institution, the speed of responding to emergency situations I was having a problem that the suitability was insufficient.

In addition, when an emergency situation is communicated through a wired or wireless telephone system, it is difficult to clearly understand the situation because the emergency situation cannot be accurately communicated, so the possibility of damage to innocent people and property can be excluded. none.

However, 24/7 monitoring of a predetermined internal space from the outside is difficult to adopt in relation to work that requires privacy or confidentiality. Therefore, there is a demand for the development of a device capable of monitoring the emergency situation of the work site only when an emergency situation occurs.

Due to these problems, technological development for enabling a camera to operate in conjunction with a detection means capable of automatically detecting various emergency situations is presented with considerable progress.

In the prior art, a number of techniques for remotely transmitting a situation of an operator by attaching a wireless camera to a safety helmet have been disclosed. For example, Republic of Korea Patent Registration No. 10-1419207 discloses that the camera is detachably separated and fixed from the external front or side side of the helmet, and after the camera is mounted, the camera can be arbitrarily adjusted in the up, down, left and right directions. While making it easy for accurate shooting, it provides a helmet with a camera mounting clamp that can be quickly and easily mounted on an existing helmet.

However, this technology has the inconvenience of installing a separate camera when it is necessary to confirm a specific location or to temporarily and continuously monitor a specific location.

In addition, Korean Patent Laid-Open Patent No. 10-2017-0040057 discloses that an installation part of a fixed main control unit having a socket part in which a camera module is installed in all directions and a GPS location tracking antenna are installed in the installation socket part to convert an image of a surrounding situation After that, it provides a control device to store and locate it, as well as a microphone and earphones.

However, this technology also has the inconvenience of installing a separate camera when it is necessary to check a specific location or to temporarily and continuously monitor a specific location.
