Description

The internet of things field control and guidance system using private communication network}

The present invention detects fire, flooding, gas, heavy snow, ground subsidence, landslides and large-scale complex disasters, earthquakes, and coastal erosion occurring at work sites through the advanced Internet of Things (IOT) in advance, and at the same time utilizing a self-communication network. By sharing the pre-detected information with the operator terminal, the manager terminal, and the head office terminal through the real-time management center server, it is possible to cope with the program type set in advance suitable for the type of accident, and the area where the workers are located at the work site and the emergency exit. It is a smart system that can support workers to safely evacuate in case of emergency by transmitting and notifying the optimal evacuation route through the management center server to the worker terminal, manager terminal, and headquarters terminal by analyzing the location and congestion level. Various sensor signals of the sensor group and images captured by various cameras of the image capture unit are collected and analyzed in real time using a self-communication network, and when abnormal signs or abnormalities occur at the work site, texts and images are sent to the operator terminal, the manager terminal, and the head office terminal. It is a technology related to an IoT field control and guidance system using a self-communication network that enables safe evacuation according to the type and characteristics of an accident by sending alarms and transmissions in real time.

When performing work in welding fields, confined spaces, underground facilities, etc., workers are exposed to the risk of disasters due to leakage of toxic or explosive gases.

As a representative case of an accident, in January 2010, a fire occurred in a workshop located in Gimpo, where production workers were carrying out a work to heat the gel-type olive oil in a container with LPG gas to liquefy it, causing five casualties. .

As a result of on-site confirmation, the LPG supply pipe was separated from the burner, and the pressure regulator spring of the LPG container was also separated to the outside, so it was confirmed that gas was leaked into the combustor. Was confirmed to have occurred.

The detection and risk evacuation method for toxic gas or explosive leaking gas in a confined space according to the prior art remains at the level of detecting gas leakage by a sensor terminal in a fixed position, so when an abnormality occurs in the sensor terminal, gas leakage There is a problem that workers in the field are still exposed to danger because they are misdiagnosed whether or not, and even if gas leaks are correctly diagnosed, evacuation notifications and evacuation routes are not adequately provided to field workers.

In addition, accidents of toxic gas leaks frequently occur in factories where semiconductor processes are recently performed, and personal and property damages are also followed by such accidents.

Since it is difficult to quickly determine the concentration or type of harmful gas by human sensory organs, various sensors to measure harmful gas are installed in the factory, but the concentration of harmful gas increases by more than a certain value through only such a sensor. There were several limitations in the method of detecting the situation and performing an evacuation notification in the factory.

In addition, in situations where industrial accidents accompanied by accidents frequently occur in complex development and various business sites, accidents are recognized using various measuring instruments, but the effective coping system is insufficient, revealing the limitations of accident prevention. .

Therefore, fire, inundation, gas, heavy snow, ground subsidence, landslides and large-scale complex disasters, earthquakes, and coastal erosion occurring at work sites are detected in advance through the advanced Internet of Things (IOT). Since the detected information is shared with the worker terminal, the manager terminal, and the head office terminal through the real-time management center server, it is possible to cope with the program type set in advance suitable for the type of accident, and the area where workers are located at the work site, the location of the emergency exit, and It is a smart system that can support workers to safely evacuate in case of emergency by transmitting the optimal evacuation route through the management center server to the worker terminal, manager terminal, and headquarters terminal. Various sensor signals and images captured by various cameras of the image capture unit are collected and analyzed in real time using a self-communication network, and when abnormal signs or abnormalities occur at the work site, real-time alarms to the operator terminal, manager terminal, and headquarters terminal with text and video. There is an urgent need to develop a field control and guidance system for IoT using a self-communication network that enables safe evacuation according to the type and characteristics of accidents by sending them.
