Description

Industrial site safety management system and method using safety helmet

The present invention relates to an industrial site safety management system and method using a hard hat, and more particularly, when an industrial accident occurs to workers wearing hard hats at an industrial site, by notifying the occurrence of a disaster by using a safety helmet immediately, the workers can quickly It relates to an industrial site safety management system and method using a hard hat, so that it can respond to a disaster accident.

In general, a hard hat is worn on a person's head to protect the person's head from the impact caused by falling objects in various industrial sites, and is a device for absorbing and protecting the impact applied to the person's head.

Safety helmets are protective equipment used in all industrial fields such as civil engineering, construction, heavy industry, shipbuilding, steelmaking, industrial plant manufacturing, road construction, and environmental beautification. Wearing a helmet is strongly recommended for safety management. In addition, various studies have suggested ways to activate the wearing of hard hats.

Here, the helmet is composed of a hemispherical head protector and a chin strap, and the head protector has a hemispherical shape with an accommodating space formed therein and is manufactured using high-strength plastic or light metal, etc. An lining composed of a dog's headrest band is installed, and the chin strap is connected to the head protector and is hung on a person's chin to prevent the helmet from completely detaching from the person when the person is active.

However, in industrial sites, even if workers wear these helmets and work, there may be safety accidents or various disasters that are not related to the helmet, such as the generation of gases harmful to the human body.

For example, if the work site is a manhole, a sewer pipe, or an enclosed space such as a water tank, the airflow may be irregular or filled with contaminated air, which exposes you to an unpredictable risk of suffocation. There is a problem that there is no guarantee that can be collateralized.

In this case, if workers in the field immediately recognize the occurrence of a disaster or accident or recognize the occurrence of an accident at a work control center, etc., it is possible to further reduce human casualties. In other words, even if a worker is suffocating when working in an enclosed work space, if the worker can be tracked or the work control center recognizes this, life can be rescued within a short time.

Therefore, it is required to develop a system that can prevent safety accidents in advance by identifying the current location of the worker at the work site and monitoring it in real time at the control station when the worker enters the hazardous area.

In the first port, the signal waveform is toggled up and toggled down, and when the toggle-up is detected again after a predetermined time elapses, tagging with the access point is recognized, and the first port is toggled. When the toggle-up signal waveform in port 2 is toggled down and toggle-up is detected again, it is recognized as a write operation of the data area, the location data and work information are read from the corresponding access address address, and the third port is accessed. a main control unit (MCU) that transmits to the control server through and counts the number of times that the location data and the job information are written to the data area;
Industrial site safety management system using a hard hat, including a.
The method of claim 1,
The control server,
Receiving the location data of the hard hat from the processing device, outputting or storing it so that an administrator can see it, and commanding that a red light is output from the hard hat when the location of the hard hat is in a dangerous area based on the location data sending predetermined control commands to the processing device;
Industrial site safety management system using hard hats.
The method of claim 1,
The safety helmet is
a GPS receiver for receiving location data from a GPS satellite;
a gyro sensor measuring the inclination of the helmet and outputting motion data;
a light emitting module for outputting light;
a communication unit for wirelessly or wiredly outputting the location data and the motion data; and
A main control unit (MCU) for controlling the transmission of the position data and the movement data, or for controlling the light output of the light emitting module
Industrial site safety management system using a hard hat, including a.
3. The method of claim 2,
The helmet further includes a shock sensor for measuring vibration generated by an external shock, and transmits the vibration value measured through the shock sensor to the control server through the processing device,
The control server receives the location data and the movement data from the processing device, determines whether the hard hat is located in a dangerous area based on the location data, and displays it on the screen, based on the movement data An industrial site safety management system using a helmet to display and output on the screen whether there is no movement of the helmet.
delete delete An industrial site safety management method using a hard hat of a system including a hard hat and a processing device interlocked through wired or wireless and an access point that communicates with the processing device in a work area,
(a) tagging the processing device with the access point when it enters a work area;
(b) transmitting the position data of the helmet and outputting general lighting through the light emitting module;
(c) transmitting, by the processing device, the location data to a control server together with job information;
(d) transmitting, by the control server, a predetermined control command to the processing device to output a red light when the hard hat is in a dangerous area based on the location data;
(e) controlling, by the processing device, to output a red light from the hard hat according to the predetermined control command; and
(f) the safety helmet comprising the step of outputting a red light by switching from the general lighting,
In the step (a), the processing device in the first port toggles the signal waveform up (toggle-up) and toggles down (toggle down), and after a predetermined time elapses, the access is again detected when the toggle-up is detected. When tagging with a point is recognized, the signal waveform toggled-up in the second port is toggled down and toggle-up is detected again, it is recognized as a data area write operation, and the location data and the operation are performed at the corresponding access address. Reading information and transmitting it to the control server through the third port, and counting the number of times that the location data and the work information are written (Write) in the data area, industrial site safety management method using a hard hat.
8. The method of claim 7,
In the step (b), the hard hat is an industrial site safety management method using a hard hat, which outputs to the processing device to transmit the movement data measured through the gyro sensor and the vibration data measured through the shock sensor to the control server.
delete 9. The method of claim 8,
In the step (d), the control server displays the position of the helmet in the work area based on the position data received from the processing device, and displays the movement state of the helmet based on the movement data, An industrial site safety management method using a hard hat to display and output on the screen so that the manager can see whether an impact has been applied to the hard hat based on the vibration data.
