Description

Smoking and fire detection and location system

This case is a disaster detection and positioning system, especially a smoking and fire detection and positioning system.

"The fire of the stars is enough to pry the original." Taiwan is narrow and dense, so many high-risk industrial security places are hidden in places where people gather, such as gas, gas stations, petrochemical plants, but these occasions also represent danger. The gas concentration is too high, only a little bit of spark can be used to explode. Although smoking is prohibited in these occasions, some addicts can't resist the episode of craving, and in these high-risk situations. Smoking, or cigarette butts throw away, it is very easy to cause gas explosion, and the birth of the product is born out of the disaster.

Old-style fire-fighting equipment uses smoke or temperature detection, must be limited to indoor use, and requires long-term detection, but we use flame ultraviolet detection, which can be accurately sensed when there is a fire source, and In addition to ordinary indoor use, it can also be used in outdoor or indoor large spaces, so we have a great advantage in detecting speed or where it can be used.

With the industrialization of industrial and technological industrial clusters, the changes in building types and disasters, and the combination of scientific and technological progress, disaster prevention is actually one of the important industries in the future. Unfortunately, because of the people’s attitude towards disasters, disaster prevention The equipment is still in the past.

In recent years, many fire disasters have occurred, such as the fire in the Karachi Garment Factory in Pakistan, which caused 246 deaths. The fire in Dali was suspected to be a fire caused by inadvertent smoking on February 4, 2004. A nightclub in Brazil on January 28, 2013 The fire caused 236 deaths, Taichung Sand Deer, a Paulilong factory warehouse, and more than 200 pings of factory buildings. The loss was estimated at 1.6 million yuan, and the Taiwan Plastics Six Light Wheat Factory was blasting.

In Taiwan, there have been an average of 13,532 fires per year in the past decade, and the average annual death toll was 272, 705 people were injured, and property losses were 3,917,270,600 yuan. In addition, the fires that occurred in the past decade due to cigarette butts occurred in 2017. The second place for the reason, and these numbers are constantly increasing.

After the Industrial Revolution, due to the clustering of factories, the general awareness of disasters, the dangers surrounding urban life, and the relatively strong security needs of the people in pursuit of living space, coupled with factors such as scientific and technological progress, the remote disaster preservation service was led. The industry outlook is promising and is expected to develop into a future star industry.

When a substance burns, it produces visible or invisible light radiation while generating smoke and releasing heat. Flame radiation is gas radiation with discrete spectra and solid radiation with continuous spectrum. Its wavelength is in the range of 0.1-10μm or wider. In order to avoid interference from other signals, ultraviolet rays with wavelength <300nm are often used, or unique in flame. The CO ₂ radiation spectrum having a wavelength of around 4.4 μm is used as a detection signal.

The UV sensor responds only to ultraviolet light in the narrow range of 185 to 260 nm and is insensitive to light in other spectral ranges, allowing it to detect UV light in the flame. The wavelength of light emitted by the solar light source and the non-transparent purple material that reaches the ground under the atmosphere is more than 300 nm. Therefore, the UV-band of the 220-280 nm flame detection is a solar spectrum blind. District (day blind area).

In addition, dangerous gas poisoning or gas explosion fire is a common disaster in China. These air pollutants have similar hazard patterns; the air pollutants with their effects have similar hazard patterns; for example, they affect the respiratory system, long-term exposure. Will form chronic lung disease, mainly dyspnea, cough, chest pain, sore throat, bronchitis, wheezing, pulmonary edema, pulmonary fibrosis, lung cancer, etc., leading to cardiovascular disease, especially when there is air In the presence of CO, CO and heme preferentially combine to form carbon black (Carboxyhemoglobin), so that oxygen in the air cannot bind to heme, and the oxygen supply capacity of the blood decreases. In addition, the release of carbon monoxide (CO-Hb) in the blood will cause insufficient supply of oxygen to cells and tissues, eventually causing poisoning and death.

Ignite the gas in the air, the gas may detonate, or it will stop quickly. Which is the case, which is determined by the concentration of gas in the air. When the gas concentration is too low, there is not enough fuel to sustain the explosion; when the gas concentration is too high, there is not enough oxygen to burn. The gas can only be detonated between two concentrations. These two concentrations are called lower explosive limit (LEL) and upper explosive limit (UEL), which are expressed as a percentage. They are the explosion limit of gas (also known as the explosion limit).

Therefore, it is necessary to design a new type of smoking and fire detection and positioning system to overcome the above drawbacks.

One object of the present invention is to provide a smoking and fire detection and positioning system having a plurality of flame sensing mode components placed in a place and having an image capturing device, when smoke or fire is detected, Multi-point positioning to locate the fire or smoke point and make The image capturing device is aimed at a fire or a smoke point for the purpose of positioning and facilitating disaster relief.
