With the development of the today's advanced industry civilization, We are always inhering a safety frigidity about disasters of various kinds when and where we may happen. The fires and disasters to be enlarged day by day are reported everyday through the mass communication. Therefore, a prevention countermeasure about the every kind fire and disaster is above all important along the social and the days requirement. As a kind of such countermeasure, this paper is proposed about automatic transmission system of disasters alarm by using wire and wireless communication network. The automatic transmission system prevents the unexpected fire or disaster from a sudden occurrence at the house, industrial field or at the place without the human. The proposed system has the characteristic of high precision and high response speed comparing with conventional system. Also, as the proposed system is small size and lightweight, the users have economic advantage and simply install the system.

Emergency exit guidance lights were designed and manufactured to quickly determine the location of the emergency exit in the event of a fire using a gas sensor, an illumination sensor, a temperature sensor, an Arduino Uno, and a Bluetooth module. This research was designed such that, when a fire breaks out, a red arrow appears as the illuminance value is low and a green arrow as the illuminance value is high to improve visibility when detecting high temperature and smoke. In addition, it is designed to prevent more serious conflagration by applying an alarm sound and text transmission algorithm using a communication module to transmit text messages indicating a 174Hz alarm sound and a fire location to prevent more serious conflagration.

This paper introduces an indoor sensor fusion wireless communication device which provides the Location Based Service (LBS) using fire prevention facility. The proposed system can provide information in real time by optimizing the hardware of Wi-Fi technology. The proposed system can be applied to a fire prevention facility (i.e., emergency exit) and provide information such as escape way, emergency exit location, and accident alarm to smart phone users, dedicated terminal holders, or other related organizations including guardians, which makes them respond instantly with lifesaving, emergency mobilization, etc. Also, the proposed system can be used as a composite fire detection sensor node with additional fire and motion detect sensors.

It is general to use the control network in control systems in order to reduce the complexity of the related wiring harnesses and to improve the system flexibility. CAN becomes one of the most popular network protocols because of its low price, multiple sources, high performance and reliability. This paper describes a CAN based real-time control of the fire detection system for the intelligent building system. The proposed fire detection and alarm system is stronger than the previous one against noises and communication media faults and can solve many problems such as complex cabling and increment of I/O ports by using many sensors. Furthermore, MMI can be achieved easily with the personal computer that is used for replacing the traditional monitoring system. The proposed system is implemented and the experimental results are given.

This study is to minimize the damage and fire early warning and research on mobile communications network of the emergency fire alarm system based on the IoT to the transmission in real time. The spread of such systems can be expected to businesses expand to technology that can replace or complement existing fire fighting system, it is also expected to a large ripple effect as an important technology that can minimize the damage to real-time detect the ignition point.

This paper is a study to dectect the tracking owing to deterioration of indoor wiring, and to prevent the electrical fire. After analysing the harmonics of waveshapes in load current and tracking current by FFT, a method of identifying the tracking was developed by using neural network. Fluoscent lamp, witch was mostly used in indoor, was chosen as the load used in this study. When the learning number in neural network was more then 30,000 times, an excellent neural net-work which could correctly identify the tracking was established. Therefore, the result of this study can be utilized as a basic material in various measuring instruments, such as an hotline inslation tester, earth tester in vehicles, and tracking fire alarm device, witch can detect the tracking under the condition of hotline.

This paper is for response feature of fire detectors not only to analysis response feature of fire detector, but also to observe flame spread of inside-building and fire enlargement by using the row house which is supposed to be broken up. Many kinds of popular detectors such as heat type detector(differential type, fixed temperature type, Analogue type)and smoke type(light scattered type, Analogue type, single alarm type) were installed in the house in order to check for the change of temperature by installing of thermocouples. As a result, smoke detectors are better than heat detectors when it comes to making effective fire-detect system in the row house.

In this paper, propose device that all of AC Power could do switching because uses fire flame sensor(UV TRON R2868) and sensor driving circuit. Used OrCAD program for analysis of consisted Power On/Off Set, and this manufactures and experimented driving circuit actually. The experimental result is considered that can refer to data of circuit design in case of apply to actual field of practical use that need alarm after sense flame, and special quality that give an alarm sensing flame in experiment wave and given environment relatively stable. With this result Power On/off Set and that action of embodied serrounding system can utilize actually verify.
