Description

DANGER ZONE SETTING WITH RTLS SENSOR}

The present invention relates to a remote collaboration system and method, and more particularly, to a system and method for deriving an occupational safety accident prevention model suitable for an industrial site of a refractory manufacturing process and supporting the remote collaboration system.

In various industrial sites including construction sites and factories, workers are exposed to many risks. For example, various risk factors such as sudden health abnormalities, generation of hazardous substances, fall, burial, collision, and collapse are inherent. Therefore, it is urgent to prepare means for preventing accidents to protect workers from such risks.

In particular, the workers at the above site are far from the outside and only a small number of people work together, and there may be cases where they are cut off from the outside. can be faced Therefore, it is urgently required to prepare an environment in which workers working in the above dangerous fields can take immediate action when a dangerous situation occurs by allowing others to recognize their health status, risk exposure, location, etc. In addition, if a means for the worker himself to recognize such a dangerous situation is provided, the accident rate can be greatly reduced.

Korean Patent Registration No. 10-1676848, which is a prior art, discloses a smart safety helmet for monitoring in real time the location information and status of a worker by having a short-range wireless communication module and an EEG sensor, and Korean Patent Registration No. 10-1787508 Ho discloses a smart work hat that expresses work-related information in augmented reality to increase work efficiency and share risk information around the user.

However, it is often limited to establishing countermeasures by immediately grasping the user's condition, and there is a problem in that it is impossible to support remote collaboration in a poor environment such as a relatively large indoor and industrial site.

Therefore, there is a need for research on safety accident prevention and remote collaboration support systems that do not have space restrictions and enable remote collaboration effectively even in a poor field environment.

The gateway 300 receives the location information of the smart device 100 and the location information of the tag 200 and transmits it to the server, and the calculation is based on the possibility of collision between the operator and the dangerous object calculated in the server. When the collision probability exceeds a preset value, a warning notification generated by the server may be transmitted to the smart device.

More specifically, referring to FIG. 2 , when worker A, forklift A, and forklift B are working at the work site, worker A is wearing the smart device 100 , and the forklift A and forklift B The tag 200 is attached to each, and the gateway 300 can collect location information through the smart device 100 and the tag 200 of the worker A, the forklift A, and the forklift B. have. The information collected through the smart device 100 and the tag 200 is transmitted to the server through the gateway 300, and in the case of the forklift A, the visibility is insufficient due to the loaded cargo. It is determined that a person or other moving object is not recognizable, and a warning notification informing of the existence and movement of the forklift A may be sent to the worker A and the driver of the forklift B located in the traveling direction of the forklift A. In addition, it is possible to transmit a notification requesting immediate visibility to the forklift A driver as well.

In addition, the smart device 100 can measure the live signal of the worker and immediately transmit a call signal to the manager terminal and rescue organization when an emergency occurs. For example, when the worker's biosignal deviates from the normal value due to a collision accident or sudden health abnormality of the worker, a call signal is immediately transmitted to the manager terminal in the area in charge, and the closest structure based on the location of the worker You can request a rescue report from the agency.
