Description

Smart IOT gas alarm system

The present invention relates to a smart gas alarm system capable of generating an alarm when working in an enclosed space where oxygen concentration is lowered or harmful gas may be generated and to easily identify the status of a worker, and will be described in more detail, When work is carried out in a closed space (hereinafter referred to as'closed work space') except for entrances such as hoppers, manholes, ducts, tanks, etc., when the oxygen concentration in the work space decreases or when harmful gases are generated, it is quickly This enables workers to recognize this and prevent safety accidents caused by low oxygen concentrations and harmful gases in advance, while monitoring the working conditions such as the working environment status of the work space where the indoor/outdoor navigation algorithm is applied and the worker's indoor/outdoor location. This is the technical field of smart IOT artificial intelligence gas alarm system that is easy to do and quick response in case of safety accidents.

In general, low oxygen concentration and harmful gases generated in steelworks and various industrial sites, especially when work is performed in a closed work space such as hoppers, manholes, ducts, tanks, etc. of underground passages, prevents the occurrence of oxygen deficiency or harmful gases and explosive gases. A safety device that protects workers' safety and property by detecting them through artificial intelligence learning in advance and warning them within seconds is essential.

The above safety devices are installed in a specific place to monitor the oxygen and gas concentration of the place, an installation-type gas detection and indoor/outdoor location detection system, and the oxygen and gas or oxygen concentration and gas concentration around the worker in the state of the worker's possession. It can be classified as a detection system that includes a portable communication function that monitors.

The portable detection system is manufactured in a smaller size than the installation type detection system, and it detects the surrounding gas and transmits the detection of the gas or the concentration of the gas to the server so that the operator can be notified immediately within a few seconds.

In connection with the above, the aforementioned harmful gas is not a big problem because workers can easily recognize it when a gas having a specific odor or color is leaked, but the concentration of oxygen is lowered, making breathing difficult due to oxygen deficiency or carbon monoxide, When a colorless, odorless gas such as carbon dioxide or nitric acid is leaked, there is a problem that the worker may be poisoned or suffocated during work or unconsciously.

The colorless and odorless gas can explode even with a small flame when the concentration in the air reaches a certain value regardless of odor or color such as LPG, acetylene, butane gas, so that leakage of the gas can be quickly detected and necessary measures can be taken. Therefore, it is important to detect leakage early in order to prevent damage caused by gas leakage regardless of the appearance of gas accidents such as explosion or suffocation.

In workplaces where gas is handled or gas may be generated due to the above-described problems, a detector capable of early detection of gas leakage, that is, a safety device capable of detecting the status of a worker (position, movement, work presence, etc.) Hereinafter, it is referred to as'gas leak detector') to protect people and property from explosions or suffocation caused by gas leaks.

However, the weight and volume of the conventional gas leak detector increased as devices with various functions were added for the purpose of improving the detection function, and this weakened the mobility of the conventional gas leak detector, so that it has to be fixedly placed only in a certain place. Therefore, when a worker's work range is large or a hole with a high probability of gas leakage is widely distributed, there is a problem that the conventional gas leak detector is inevitably turned into useless.

In order to solve this problem, a portable gas leak detector that an operator can carry has been developed, and such a conventional portable gas leak detector activates an alarm sound or an alarm once a gas leak is detected, so that the operator can visually or audibly recognize it. It is supposed to be able to.

However, such a conventional portable gas leak detector is usually installed on a worker's helmet so that the worker's work can be performed smoothly.When installed on the helmet, an alarm sound and an alarm are operated above the worker's field of view, making it easier for the worker to work There was a problem that occurred when not recognizing.

In addition, conventional portable gas leak detectors are sometimes not installed on the helmet but on the worker's clothes in order to improve the worker's cognitive ability. there was.

In addition, when a safety accident occurs in a closed work space as described above, the worker reaches a dangerous state regardless of whether or not the worker is aware of it.In this case, when there is no other worker nearby, it is left in a dangerous situation, resulting in greater accident or personal injury. Can occur.

That is, even if an installation-type gas leak detector or portable gas leak detector is installed or carried, safety accidents may occur due to various causes such as low oxygen concentration in the work space or generation of harmful gases, or the chronic illness and condition of workers. If the central control department or manager located outside the space does not contact the worker, it is difficult to recognize the accident, and if the work location of the worker is changed due to the occurrence of an accident or other factors, the discovery of the worker where the accident occurred is delayed, leading to a more dangerous situation. There is a problem that can go on.

In addition, when a safety accident occurs as described above, it is difficult for the rescue team to easily enter the work space due to the low oxygen concentration or the generation of harmful gases in the environment of the work space, and it is difficult to grasp the environment of the work space, which delays the response. There is a problem that it is difficult to quickly take measures according to safety accidents.

In addition, in the case of a conventional gas leak detector, a communication network can be used to transmit an alarm or an accident to the central control unit or manager outside the work space. In this case, since the portable gas leak detector is carried by each worker, monitoring of the work space There is a problem that is difficult to be applied in practice due to the increased communication cost required.
