It relates to a smart LED disaster alarm system and alarm method.

The contents described in this section are merely to provide background information on the embodiments of the present invention, and do not constitute prior art.

Lighting is an essential element in human activities as a means of conveying visual information. Most of the lighting uses electricity, which is an expensive energy, and application fields as a means of maintaining a pleasant environment and various information transmission from simple lighting are increasing, and the usage is also increasing significantly. In the 21st century, the revolution of light is starting, and semiconductor lighting using high-brightness LEDs is the leading role.

With the epoch-making development of semiconductor technology, not only the three primary colors of light, such as red, green, and blue, but also visible light, infrared light, and ultraviolet light, and white light can be made using it. The wavelength of light emitted from the sun covers a wide range of wavelengths, from short ultraviolet rays to visible rays with wavelengths that can stimulate human vision, and infrared rays with long wavelengths. The creation of artificial visible light to use among these lights for lighting actually started a long time ago. In other words, there has been endless development from prehistoric bonfires to lanterns and gas lamps to modern incandescent lamps and fluorescent lamps. However, in fact, it can be said that the origin of artificial light sources for lighting began with the carbon filament incandescent bulb invented by Edison. In the early 1940s, the advent of fluorescent lamps in which ultraviolet rays generated by discharge excite calcium halophosphate phosphors and convert them into visible rays reached a situation where they became mainstream as a very important light source for home and industrial lighting.

With the advent of such artificial light sources, the atmosphere of the times that gave a lot of changes and prosperity to the lives of mankind, culminating in the oil shock of the 1970s, emphasized energy conservation in all areas of society. Fortunately, the conventional low-brightness visible light LED, which was mainly used for simple displays and dials, has recently emerged as high-brightness red, orange, green, blue, and white LEDs due to the recent development of compound semiconductor technology. Applications have become possible in various fields. In particular, the emergence of white LEDs has led to the use of LEDs as illumination light sources as the lighting efficiency of LEDs exceeds incandescent bulbs.

On the other hand, many LED lights are installed on the ceiling of each building, but the current LED lights only perform a lighting function, and in disaster situations such as fire or earthquake, it provides a disaster evacuation route based on the user's current location. Not.

12 is a flowchart illustrating an operation process of the smart LED disaster warning system according to an embodiment of the present invention, and is an operation process using a signal transmitted from the sensor unit 300.

In the embodiment of Figure 12, the user carrying the tag unit 400 is a corridor or stairs inside a building in which a plurality of LED lighting units 100 are spaced apart, a specific space such as an office or toilet inside a building, or a building such as an underground parking lot It is assumed that a disaster situation is detected by the sensor unit 300 while entering an auxiliary facility.

First, the tag unit 400 carried by the user periodically or aperiodically transmits the identifier information to the first communication module 110 of the LED lighting unit 100, and the identifier information is transmitted to the relay unit 200, the gateway ( Since it is transmitted to the control server 500 via GW), the control server 500 is a situation in which the user's current location can be checked in real time. (S210)

The sensor unit 300 generates sensing information in the sensing area and transmits it to the first communication module 110. (S220) The sensing information may simply be a measured value measured by the sensors 310 to 350, or may be disaster situation information determined by the sensors 310 to 350 based on the measured value. In the case of a simple measurement value, it is possible to determine whether a disaster situation exists based on a reference value set in the server control module of the control server 500.

The thermal sensor 310, the smoke sensor 320, etc. generate sensing information about a fire, and the shock sensor 350 generates sensing information about an earthquake. The occupancy sensor 330 is not disaster situation information, but generates population density information in the detection area and transmits it to the control server 500. The air quality sensor 340 generates sensing information on the air quality in the detection area and transmits it to the control server 500. Population density information can be used as standard information to determine the priority of rescue in a disaster situation, and air cleanliness information can be used as standard information to determine whether the air purifier installed in the detection area is operated.

The LED lighting unit 100 receiving the sensing information transmits it to the second communication module 210 of the relay unit 200. (S230) Meanwhile, since the shock sensor 350 is installed on a wired cable connecting the relay unit 200 and the relay unit 200, the sensing information of the shock sensor 350 is relayed without passing through the LED lighting unit 100. It may be transmitted to the second communication module 210 of the unit 200.

The second communication module 210 of the relay unit 200 transmits the received sensing information and the unique location information of the relay unit 200 to the control server 500 through the gateway GW. (S240)

The control server 500, which has received the sensing information and the unique location information of the relay unit 200, highlights and visualizes the location on the indoor electronic map (S250), and displays the location information and the disaster situation information to the relevant institution. send. (S261)

In addition, the control server 500 generates a disaster evacuation route that can avoid a disaster situation based on the current location using an indoor electronic map. (S262) Steps S261 and S262 may be performed simultaneously or may be performed in reverse order.

The control server 500 generates a lighting control command to guide the generated disaster evacuation route, and transmits it to the corresponding relay unit 200 through the gateway GW. (S270)

The relay unit 200 receiving the lighting control command transmits it to the LED lighting unit 100, and the LED lighting unit 100 receiving the lighting control command controls the on/off of the LED light source according to the lighting control command to the user. Provide disaster evacuation routes. (S280, S290)
