Abstract:

Every year, approximately 100 people die in fire related incidents in Sweden. ”Seek” is designed to assist fire fighters to locate people faster in smoke diving procedures. ”Seek” identifies people and possible dangers within the building before the smoke diving procedure begins. This allows the operation to be streamlined and planned, as well as avoiding risks which fire fighters are exposed to today. The early overview created by the ”Seek” smoke detector not only saves time in planning but reduces the time from accident until the people in the burning building can receive skilled care, i

Abstract:

This report describes an investigation into the prediction of the activation times of domestic ionisation and photoelectric smoke detectors within a two storey dwelling, the work undertaken being an extension to that previously presented by Brammer (2002). Three fire scenarios are considered, each having been a real test fire undertaken at the Building Research Establishment in Cardington. These three fire scenarios all involved the flaming combustion of an upholstered armchair within the lounge on the Ground floor. During the experiments various results were recorded, including temperatures,

Abstract:

Entry resistance in smoke detectors was investigated using experimental and analytical approaches. The experimental work consisted of measuring velocity inside the sensing chamber of smoke detectors with a two-component Laser Doppler Velocimeter and exposing addressable smoke detectors to four different aerosol sources. The velocity measurements and exposure tests were performed in NIST's Fire Emulator / Detector Evaluator under steady state flow conditions in the range of 0.08 to 0.52 m/s. The addressable detectors were a photoelectric and an ionization detector. A specially constructed recta

Abstract:

Traditional smoke detection methods need sensors close to the source of the smoke. In order to avoid this disadvantage, this thesis presents a method for indoor video based smoke detection. In addition, it helps to improve the success rate of detection, as well as reducing the false detection rate of suspected smoke. This method consists of two parts. First, we create a Gaussian mixture model to detect smoke color pixels. Then, we use the smoke’s dynamic features to detect the smoke area and extract it from the area found in the first step, and in that way we can find the real smoke area. Our

By utilizing principal component analysis (PCA) followed by spatial filtering of principal component images the location of smoke can be accurately identified over a period of exposure time with a given frame capture rate. This result can be further analyzed with consideration of wind factor and fire detection range to determine if a fire is present within a scene.

How to catch the moving objects in the foreground and separate smoke from vehicles is a fresh and difficult issue for environment protection.In the study, a method that combined temporal-spatial and color information is used to select the features of moving object and then detects that the smoke exists in the image or not.First, histogram of statistic pixels is adopted for background rebuilding.An approach that combined temporal-spatial and angle-module to find moving o

碩士<br>國立中山大學<br>機械與機電工程學系研究所<br>93<br>Recently, plenty of large/public buildings have been completed in Taiwan. For bright indoor environment and comfortable feelings, these buildings often utilized lots of large spaces such as atria. However, it is difficult to maintain tenable conditions within atria and large spaces in case of fire. Therefore, the alert of smoke detectors and the efficiency of smoke control systems are both very important when a fire occurred and people needed to evacuate. In large space buildings, the smoke exhaust fan and smoke storage are major design concepts of the p

In this thesis, we develop a video-based fire and smoke detection system based on the random forest algorithm. We use the distinct color and image variation properties of fire/smoke to select candidate regions. Then, image features of texture and motion patterns of the candidate regions are analyzed to determine any fire/smoke region. We pr

Abstract:

A Very Early–warning Smoke Detection Apparatus (VESDATM) detects the earliest traces of smoke by continuously sampling the air from a designated area. Air sampling is achieved by use of a system of long pipes containing numerous small inlet orifices termed as sampling holes. The air samples are drawn to the detector by means of an aspirator. In spite of the high sensitivity of the detector, much of this advantage can be lost if the smoke transport time within the pipe network is excessive. Consequently there has been a legislation introduced by Standards such as AS 1670 and BS 5839 stating the

In this thesis, study on a new method of smoke detection based on RGB color model mainly. At first, using a mould that represents with RGB model parameters separates out the smoke from the image and according to the characteristic that smoke moves upward.

Abstract:

碩士<br>國立成功大學<br>機械工程學系專班<br>97<br>Conventional fire detectors must contact these targets（heat or smoke） for being activated and, consequently, respond slowly. Video smoke detection has many advantages over traditional methods, such as fast response and non-contact, large space surveillance, and so on. But most of current methods for video smoke detection systems usually have high false alarms. By analyzing the characteristics of smoke motion, base on blocking image, a motion accumulation and translucence combined model is proposed for video smoke detection. Because smoke often emerges continua

In this thesis, target tracking method and the properties analysis of smoke are used to confirm whether there is smoke in the video. First, moving objects in video are detected by using Gaussian Mixture Model algorithm, then labeling disconnected areas as different parts. After labeling, the location of current image components and previous image components are compared to confirm whether the same components, then the smoke features of each component are extr
