Description

System for monitoring a emergent situation using a smart helmet and the method thereof

The present invention relates to a risk monitoring system and method using a smart helmet, and more specifically, when an emergency occurs to the worker using various sensors mounted on the smart helmet and a smart device carried by the worker. The present invention relates to a risk monitoring system using a smart helmet and a method for promptly responding to an emergency situation of a worker by notifying a control center or the like.

In the case of a facility where a facility is built over a wide area such as a power plant, a refinery, or a steel mill, and workers work in each facility in a wide area, a very large number of workers work in various facilities and the area where the workers are working This is extensive. At this time, it is difficult to recognize when an operator occurs in a specific area and falls, or if a situation occurs, such as a danger situation caused by equipment. As a result, if it is promptly dealt with, it can be resolved without leading to a human accident. In spite of the situation, many unfortunate things happen, such as inflicting fatal injuries to workers due to lack of immediate response.

In order to prevent such a sad situation, various types of safety management devices and systems have been proposed, and there are a number of methods for detecting and responding to dangerous situations for workers by installing various sensors on a helmet worn by a worker. It has been proposed.

Referring to the domestic registration patent No. 10-2017-0018747, a conventional worker safety management system using a helmet is a smart helmet that collects and transmits information on a work site, a smart helmet that collects biometric information and real-time location of a worker, Smart repeater that relays wireless communication between smart hell and smart devices and management server,

It consists of a management server that processes and controls one real-time information, and includes one or more LED lights that are installed on the work site and transmit the position of the worker to a smart helmet through visible light communication. The biometric information and location information about the worker collected from the smart helmet is transmitted to the smart device through short-range wireless communication such as Bluetooth. The smart device collects information about the environment of the work site and transmits it to a smart repeater by supporting wireless communication such as Wi-Fi or a mobile communication network (CDMA, LTE, etc.) along with the worker's information received from a smart helmet. . The smart repeater transmits the information received from the smart device through a wired or wireless communication to the management server, and transmits information on the work site received from the management server, that is, an emergency message to the smart device. The smart device notifies the operator of the emergency or danger warning by sending the emergency or danger message to the smart helmet.

However, the conventional safety management system using the helmet uses a method of determining the safety state of the worker by informing the position of the worker or using the biosignal of the worker, but the worker suddenly becomes conscious by gas generated from the equipment. In the event of a loss or collapse situation, or a situation where a worker is seriously injured by the facility and collapses, etc., it is not possible to immediately detect this situation and provide a function to notify the control center promptly. There was a problem in that it was difficult to immediately respond to the danger situation of the worker by detecting this and notifying it to the control center only when the function had to be deteriorated.
