Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a portable disaster rescue device,

The present invention relates to a method and apparatus for detecting smoke that is a sign of a fire by detecting ambient air in a natural induction manner by the hydrodynamic action of anion air generated in the apparatus without using an electric fan, And air purifying function that provides a way to escape from the disaster area by securing the field of view by the red LED power source by the smoke and the method of preventing the suffocation due to the smoke and the smoke gas To a portable disaster relief device.

Generally, fire detectors are used in large-area buildings such as buildings and apartments, and detectors of interlocking type that operate in conjunction with a central control type disaster prevention system, detectors that operate individually in small-sized buildings such as single- There is a sensor of formula structure.

These individual detectors are fixedly mounted on the ceiling of the area so as to monitor the monitoring area determined by the Fire Service Act. Since the conventional individual detector does not have the function of sucking the ambient air, it takes a considerable time for the smoke to flow into the detector due to natural convection, so that the fire has progressed considerably and smoke alarm and smoke gas are already generated. It will be announced.

Also, conventionally, an emergency lighting device corresponding to an emergency flash which outputs white light for safe evacuation when a fire occurs is provided.

However, the conventional emergency flash which outputs white light has a problem that the distance that can be illuminated is extremely shortened when a fire occurs because the smoke particles are scattered by diffuse reflection of smoke particles.

In other words, conventionally, in order to prevent the damage of human life when a fire occurs, there is no means for early detection of the risk of fire by continuously sampling smoke in real-time within about 1 meter.

In addition, conventionally, the portable air conditioner may be placed around the bed, brought to a business trip, a trip or an outdoor camping place, or a place where a smoke detector installed on the ceiling may operate, There is no means to detect fire by sampling.

Accordingly, in recent years, as described above, it is possible to easily carry the user and change the installation and the position thereof at a place where there is a possibility of a fire, such as a house, a business trip, a trip, an outdoor camping ground, and / And it is urgent to develop an emergency lighting device that can secure a longer viewing distance for safer evacuation even in the case of a smoke in a fire.

Korean Patent No. 10-0983539 (September 15, 2010) Korean Patent Registration No. 10-0827411 (Apr. 28, 2008) U.S. Pat. No. 7,995,322 B2

A first object of the present invention to solve such conventional problems is to propose a method of inducing ambient air into an apparatus without using an electric fan.

It is also a second object of the present invention to provide a method for preventing asphyxia by the smoke of smoke and the smoke gas.

In addition, the third object of the present invention is to provide a method for securing a field of view by a red emergency light, in which a white emergency light is blurred due to diffuse reflection due to smoke and smoke gas particles in a fire scene filled with smoke and smoke gas. .

In order to attain the above object, the present invention has the following device configuration.

A portable disaster rescue apparatus having an air purifying function according to the present invention is a portable disaster rescue apparatus having a built-in air purifying function capable of detecting and purifying fine dust, yellow dust, odor, and noxious gas, An anion generator for generating negative ions by applying energy to the sucked air to purify the air; a sensor unit for sensing at least one of noxious gas, smoke and fine dust; A red LED emergency light output unit for outputting red light emergency light as a red LED, an alarm unit for outputting an alarm alarm, and an alarm unit for receiving an alarm signal of the sensor unit and controlling an alarm unit if at least one of dust, And a control unit for outputting an alarm alarm and controlling the emergency light output unit of the red LED so as to light the emergency light, The power generation unit includes an anion generator for purifying air with an anion generated by a high voltage corona discharge. The housing includes an air flow tube for guiding the air sucked at the suction port to the anion generator, and a discharge port for discharging purified air from the anion generator An anion generator includes a generator cone for inducing an anion wind by the Venturi air pressure difference so as to extend the diameter from the lower side to the upper side so as to discharge the purified air from the suction port and the discharge port, And a cathode terminal fixed to a circumference of the discharge port formed at an upper portion of the power generating cone, the positive terminal being connected to a positive power terminal, And provides a portable disaster relief device with built-in functions.

Therefore, since the air is discharged from the apparatus in an anionized state, the surrounding air is guided and sucked by the surrounding air. Such suction of the ambient air into the apparatus may not require a separate suction fan.

Therefore, the surrounding air flows into the intake port of the lower part of the apparatus, and detects the danger of fire in real time through the sensor unit which detects the noxious gas, smoke particles and fine dust. In case of fire, the anion air generated from the power generation cone in the device cleans the smoke and soot gas in the event of a fire and is discharged to the upper outlet, thereby preventing asphyxia due to fire smoke and smoke gas.

In addition, according to the present invention, when the concentration of the smoke particles in the smoke detection area exceeds the fire reference value, a fire alarm is issued and at the same time, the built-in red LED emergency light is turned on. White light can not be secured in smoke view due to diffuse reflection by smoke particles. Red light with longer wavelength than white light has penetration power in smoke, so it is possible to secure visibility in smoke, so that quick and safe evacuation in emergency can be achieved.

In addition, the present invention provides a portable disaster prevention function in case of a fire capable of both air purification and fire detection, emergency lighting, and is capable of protecting the user's health from fine dust, yellow dust and noxious gas .

1 is a view showing an example of wearing a portable disaster rescue apparatus having an air purifying function according to the present invention.

Referring to FIG. 1, a portable disaster rescue device 1 with an air purification function according to the present invention allows a user to hang his or her neck as a pendant. Here, the front surface of the portable disaster relief device 1 having the air purification function of the present invention can be manufactured so that the company ID card can be inserted therein.

As shown in FIG. 1, the portable disaster rescue apparatus 1 having the air purifying function of the present invention is made to be portable, more preferably thinner and lighter, and is usually made of fine dust, It is possible to purify harmful gas and to detect smoke or toxic gas generated in the event of fire and to alarm the occurrence of fire.

Also preferably, the present invention further comprises a lighting device capable of ensuring a long visible distance in a smoky situation.

As described above, the present invention discloses a portable disaster relief apparatus having an air purification function capable of both air purification, fire detection, and emergency lighting, and a more detailed configuration will be described below.

FIG. 2 (a) is a perspective view showing a portable disaster rescue apparatus having an air purifying function according to the present invention, and FIG. 2 (b) is a charging stand. 3 is a block diagram of a portable disaster rescue device having an air purifying function according to the present invention.

Referring to FIGS. 2 and 3, a portable disaster rescue apparatus incorporating an air purifying function according to the present invention includes a housing 100 to which a necklace means is connected, and a housing 100, which detects noxious gas and smoke smoke particles inside the housing 100 A red light output unit 240 for outputting red LED emergency lights, a device power switch 270 and an alarm unit 260 for outputting a fire alarm signal A memory 280 for storing the setting reference, an anion generator 220 for generating negative ions, and a controller 230 for performing a device operation flow chart shown in FIG.

The housing 100 has a suction port 110 through which air flows into the lower portion and three or more discharge ports 120 through which anions are outputted from the upper portion.

The sensor unit 250 includes a gas sensor 251 for detecting noxious gas contained in the air to be introduced, a particle sensor 252 for detecting concentration of smoke and fine dust concentration, a gas sensor and a particle sensor 252 And an A / D converter 254 for amplifying and A / D-converting the detection signal of the A / D converter 252 and outputting it to the controller 230.

In this case, the particle detection sensor 252 irradiates the LED light to the air introduced into the particle detection area 132a for detecting smoke and dust, as shown in Fig. 6 (a) An optical sensor composed of LEDs 252a and 252c and photo detectors 252b and 252d may be applied to output a comparative electrical signal.

The gas sensor 251 is connected to a gas detection sensor (not shown) provided on the inner wall of the noxious gas sensing chamber 132b shown in FIG. 6 (b) for sensing noxious gas contained in the air introduced from the inside of the housing 100 253 to detect the concentration signal of the combustible gas such as carbon monoxide and methane, and outputs it to the control unit 230. [

The A / D converter 254 amplifies and converts the analog signals output from the gas sensors 251 to 253 to the photodetectors 252b and 252d that detect light scattered by the smoke particles, .

Alternatively, the sensor unit 250 may further include a temperature sensor for sensing the ambient temperature.

The power supply unit 210 includes a battery 213, a connector 211 for outputting external power to the battery 213, and a BMS (Battery Management Unit) 212 for detecting the presence / And a power regulator 214 for supplying constant power to the negative ion generator 220 and the load of each circuit even when the voltage of the battery 213 is changed.

The battery 213 can be charged by an external power source input through, for example, a mini USB connector 211 as a lithium ion secondary battery.

The BMS 212 senses a temperature, an overvoltage, and a charged amount when the battery 213 is charged, maintains the set abnormal reference, and outputs an abnormal detection signal to the controller 230. Also, the BMS 212 manages the battery 213 so as not to over discharge the battery 213, and outputs the discharge state to the controller 230.

The memory 280 stores sensor calibration data, alarm setting reference data, and a device operation flow chart program shown in FIG. The set criterion includes the concentration of smoke and fine dust which is set by issuing an alarm, and whether or not gas is detected.

The red LED emergency light output unit 240 includes a red LED emergency light 241 for outputting red light and an LED driver 242 for driving the red LED emergency light 241 under the control of the control unit 230.

The red LED emergency light 241 is a red LED that outputs red light and is fixed to a reflection plate 243 which is installed to be exposed through an opening formed in a side surface of the housing 100.

Here, the red light has a higher transmittance than the white light in the air having a large amount of smoke particles, and the distance illuminated in the fire scene is long. As described above, light scattering due to fine particles in the air is an optical law disclosed by Rayleigh scattering law that the shorter the light wavelength is, the larger the light transmittance is, the smaller the light transmittance is. In other words, the white light is mixed with the three primary colors of red, green and blue so that the amount of light which is 2/3 of the whole white light amount is lock, blue is shorter than that of red and the light scattering is large and the amount of light passing through the smoke is reduced, But if the total amount of light is red, the light scattering is reduced by 2/3 and the visible distance by 3/2 is increased.

 That is, according to the present invention, the user can output the red light in a short visible distance due to smoke or dust, thereby providing the user with an extended viewing distance as compared with a portable lighting device (e.g., flash) using white light.

The switch 270 is a device power switch.

 The alarm unit 260 emits an alarm sound under the control of the control unit 230 and simultaneously lights the red LED emergency lighting lamp 241.

The negative ion generator 220 includes high voltage amplifying means 221 for amplifying the power supplied from the battery 213 to a predetermined high voltage level (for example, 3 to 4 kv) And an anion generator 222 for generating negative ions. The detailed configuration will be described with reference to FIG. 4 attached hereto.

4 is a simplified view of the negative ion generator 220 in the present invention.

Referring to FIG. 4, the power supplied from the battery 213 is amplified by the high voltage amplifying means 221 to a high level of the set level, and supplied to the negative ion generator 222. The high-voltage amplifying means 221 corresponds to a device used in a personal necklace-type small-sized air purifier generally sold on the market, and thus a detailed description thereof has been omitted.

The negative ion generator 222 includes a needlepoint negative terminal 222c at the lower side to which a negative high voltage is input and a ring type positive terminal 222a at an upper opening to which positive power is supplied, And a power cone 222b extending from the lower part to the upper part in a cone shape.

Here, the power cone 222b has a channel extending between the cathode terminal 222a and the anode terminal 222c. In the power cone 222b, the diameter increases from the lower side where the anode terminal 222c is located to the upper side where the cathode terminal 222a is located As shown in Fig. This pipeline design is intended to realize the venturi effect, which has the effect of increasing the air flow by increasing the air pressure difference between upstream and downstream with small diameter. Therefore, anionization of the air increases. The anode terminal of the needle point type is dense at the point of electrons, and the corona discharge easily occurs at the high voltage of the negative voltage inputted to the connecting terminal, thereby efficiently anionizing the surrounding air. The thus generated negative ion air is attracted to the upper positive electrode terminal and discharged to the discharge opening 120 having the upper opening. Thus, the low air pressure formed by the air movement inside the apparatus induces the ambient air to the suction port 110 at the lower portion of the apparatus.

That is, in the present invention, not only the air sucking fan is provided but the air introduced into the set space is generated as negative ions and moves toward the upper direction where the positive electrode terminal 222a is located, The air pressure inside the housing 100 is reduced. Accordingly, when the air pressure inside the housing 100 is reduced, the outside air is naturally induced and sucked by the air pressure difference between the outside and the housing.

The anode terminal 222a is fixed in a ring shape on the circumference of the open upper surface of the power generation cone 222b and the anode terminal 222c in the form of a needle point contacts the cone at the center of the open lower portion of the power generation cone 222b .

The control unit 230 drives the LED driver 242 to turn on the red light LED emergency light 241 when the sensing signal of the sensor unit 250 reaches the fire level and simultaneously operates the alarm unit 260 to emit a fire alarm .

When the lithium ion battery 213 is connected to the external power source through the USB connector 211, the BMS 212 automatically checks the state of the battery. If the battery 212 needs to be charged, the BMS automatically switches to the charging mode and starts charging During charging, it monitors the charging current to match the chemical performance of the battery. It monitors the temperature of the battery to see if the battery is overheated. Also monitors the battery to prevent overcharging. When the external power supply is disconnected, the battery is automatically discharged. When the battery reaches the overdischarge state, if the overdrive signal is sent to the control unit, the control unit issues an overdischarge alarm.

The housing 100 forms an air flow pipe 130 for inducing and sucking outside ambient air due to a decrease in air pressure inside the apparatus due to the external discharge of the negative ion wind as described above.

Here, the air flow pipe 130 is installed with the anion generator 222 through the particle sensing area 132a and the noxious gas sensing area 132b sequentially from the inlet so as to sense the noxious gas, dust, To a supply room (not numbered). In other words, the air flow pipe 130 forms a flow path through which the inducted air flows.

The air flow pipe 130 of the housing 100 will be described with reference to FIG. FIG. 5 is a diagram illustrating an internal structure of a portable disaster rescue apparatus having an air purifying function according to the present invention.

The housing 100 is extended upward from the suction chamber 131 in which the suction port 110 through which the air is sucked and flows upward through the noxious gas sensing area 132b and the particle sensing area 132a, A flow pipe 130 and a discharge port 120 formed on the power generation cone 222b of the anion generator 222 for outputting purified air outward.

The air inlet 110 is formed at least in the left and right sides of the lower portion of the housing 100 to allow external air to flow therein. As described above, the present invention generates negative ions by corona discharge of the introduced air, and reduces the internal air pressure due to the negative ion wind generated when the negative ions move along the power generation cone 222b, . In other words, it does not use the electric fan but induces the outside ambient air inductively.

The suction chamber 131 is a space communicating with the suction port 110 to receive ambient air introduced and sucked in. The suction chamber 131 receives the air sucked from the suction port 110 so that the air inside the apparatus is anionized by the negative ion generator 222 and is drawn to the upper positive electrode terminal 222a and discharged to the moving discharge port 120 This is a space in which ambient air outside is induced and sucked due to a decrease in internal air pressure.

The air flow pipe 130 is divided into a supply chamber (not indicated in the drawing) in which the power generation cone 222b is fixed and two regions of the noxious gas detection region 132b and the particle detection region 132a are located above the suction chamber 131, And is directly connected to the anion generator 222 on the upper side.

At least one gas sensor 251 fixed to the inner wall of the air flow pipe 130 at least facing each other is fixed to the noxious gas detection region 132b. The gas sensor 251 uses a metal oxide type semiconductor gas sensor or a graphen gas sensor. As the ambient air passes through this zone, if there is carbon monoxide and combustible gas in the air, a signal proportional to the concentration is generated. The signal is converted into digital data by the A / D converter 254 and output to the control unit 230 .

The particle detection sensor 252 detects the concentration of dust and / or smoke contained in the air flowing through the particle sensing area 132a by installing at least one sensor around the air flow pipe 130, .

6A, the LED 1 (252a) is positioned at a position of 0 degree with respect to the diameter of the air flow pipe (130) through which the air passes as shown in FIG. 6 (a) And another photo detector 1 (252b) facing the LED 1 252a. In the LED 1, another LED 2 252c is installed at an angle of 45 degrees in the clockwise direction, and another photo detector 2 252d.

The two LEDs 252a and 252c emit blue light to the air passing through that area. Blue light striking smoke particles or fine dust in the air is reflected in all directions. The more the concentration of the particles is, the more the reflected light is. Also, as the intensity of the LED light to be irradiated increases, the intensity of the reflected light increases. Therefore, the output signal of the photodetector that receives the reflected light and emits the electric signal must be corrected to the intensity of the irradiated LED light source. The present invention applies the following correction algorithm.

DS = DS2 - DS1

Where DS2 is a corrected photodetector signal, DS2 is a photodetector 1 252b signal facing the LED 1 252a, and DS1 is a photodetector 2 252d signal not facing the LED 2 252c.

The corrected photodetector signal DS is amplified and converted into digital data by the A / D converter 254 and output to the controller 230. [

This photodetector signal is operated in the linear operating region shown in FIG. 9, and the photodetector signal DS corrected at two actually given particle concentrations A, B is calibrated and set as an operating region.

6 (a) so that the two photodetector signals are not interfered with the two LEDs 252a and 252c.

Accordingly, the control unit 230 receives the detection signal of the sensor unit 250 converted and amplified by the A / D converter 254, receives the detection signal according to the concentration of the noxious gas, fine dust, and / or smoke, 280). ≪ / RTI >

One or more discharge ports 120 are formed on the upper surface of the housing 100 and each discharge port 120 is formed to communicate with the upper opening of the power generation cone 222b. Although the number of the discharge port 120 and the number of the negative ion generators 222 shown in the figure is three in total, it is not limited thereto, and the number is not limited.

The present invention includes such a configuration, and a control method of a portable disaster rescue apparatus having the air purifying function built in through the above-described configuration will be described with reference to FIG.

7 is a flowchart showing a control method of a portable disaster rescue apparatus having an air purifying function according to the present invention.

Referring to FIG. 7, a method of controlling a portable disaster rescue apparatus having an air purifying function according to the present invention includes an anion generation and induction step S10 for sucking ambient air through induction inhalation, (S20) for detecting noxious gas and / or smoke and fine dust concentration among the sucked ambient air, an alarm determination step (S30) for determining whether or not an alarm is issued according to whether or not the detection level is above a set reference, An alarm step S40 for issuing an alarm when smoke or dust or noxious gas above the set reference is detected in step S30; and an optical output step for automatically outputting an alarm sound and a red LED emergency light after the alarm step S40 (S40), and a smoke and flue gas air purification step (S50).

The negative ion generation and induction step S10 is a step in which the controller 230 drives the negative ion generator 222 to generate negative ions and induce ambient air. The control unit 230 drives the power regulator 214 to output the power charged in the battery 213 to the high voltage amplifying unit 221. Therefore, the negative ion generator 222 is configured so that the positive and negative power amplified by the high voltage amplifying means 221 are outputted to the positive electrode terminal 222a and the negative electrode terminal 222c, respectively, And discharges to generate negative ions.

Here, the power cone 222b has a larger diameter as it extends from the lower part to the upper part, thereby increasing the air pressure difference between the lower part and the upper part by inducing the Venturi effect, thereby increasing the amount of negative ions generated in the negative terminal 222c, The change in air pressure inside the housing 100 can be increased. Accordingly, the air introduced into the negative electrode terminal 222c is corona discharged and becomes negative, and is discharged to the outside through the discharge port 120 while being moved to the upper side of the power generation cone 222b.

The negative ion generator 222 discharges the negative ion wind through the discharge port 120 communicating with the upper side of the power generation cone 222b by the Venturi effect of which the diameter gradually expands. The external air can be induced and sucked.

That is, the air pressure inside the supply chamber is reduced due to the generation of negative ions by the power generation cone 222b, and the air in the air flow pipe 130 and the suction chamber 131 is moved to the supply chamber as the air pressure decreases. Further, as the air in the suction chamber 131 is moved through the particle sensing area 132, the outside air is sucked through the suction port 110.

Here, the portable disaster rescue device having the built-in air purifying function according to the present invention can be manufactured in the form of a necklace so as to be positioned close to a user's respirator (for example, a nose or mouth).

The control unit 230 drives the light emitting display element to detect an abnormality of the battery 213 if the abnormality detection signal such as an overtemperature or an overvoltage of the BMS is received or the charged amount of the battery 213 is less than the set reference value, Or not.

Accordingly, the user confirms an alarm of the light emitting display device installed on the outer surface of the housing 100 and inserts the battery into the upright charging stand 216 shown in FIG. 2 (b) to which the power cable is connected to the connector 211, 213). The connector 211 preferably includes a USB terminal.

The control unit 230 controls the light emitting display device to display the fact that the battery 213 is being charged when the external power source is charged with the battery 213 through the connector 211. [

That is, according to the present invention, since the lithium ion secondary battery that can charge the battery 213 is used, the replacement cost of the battery 213 of the user can be reduced.

For example, the control unit 230 issues an alarm if the air contains noxious gas, or if the concentration of dust and / or smoke is equal to or higher than a predetermined standard.

The alarming step S30 is a step in which the control unit 230 determines whether a fire has occurred, a leakage of noxious gas, or an increase in fine dust through smoke concentration and / or noxious gas, and issues an alarm according to each situation.

Here, the present invention can separately set an alarm reference and a lighting reference of a red LED emergency lighting. For example, when the dust concentration is equal to or higher than the preset reference, the controller 230 may issue an alarm to alert the user to the entrance and exit of the outside and the outside air into the room.

Alternatively, the control unit 230 can set a fire detection standard through detection of smoke and gas so as to determine whether a fire has occurred through the detection signal of the smoke sensor 252 and the detection signal of the gas sensor 251 have.

More preferably, the present invention may further include a liquid crystal display (not shown) so that the user can accurately inform the user of the current state by displaying the concentration of fine dust or the presence or absence of fire detection as characters.

Accordingly, when the fine dust concentration is higher than a preset reference, the controller 230 drives the alarm unit 260 to alert the fine dust. That is, the control unit 230 can output a voice signal such as " fine dust is high "

Alternatively, when the concentration of the smoke and the noxious gas are simultaneously detected, the control unit 230 determines that a fire has occurred and turns on the red LED emergency lighting lamp 241 to visually express the occurrence of the fire, (260).

The alarm sound output and the red LED emergency light output step S40 is a step in which the control unit 230 lights the red LED emergency light 241 and issues an alarm sound when a fire is detected.

The red LED emergency light 241 is fixed to the center of the reflection plate 243 protruding from the outer surface of the housing 100. Accordingly, the red LED emergency lighting lamp 241 emits red light and illuminates the surroundings while forming a focal point by the surrounding reflection plate 243.

Here, the red light has a longer wavelength than that of the white light, and can provide a longer viewing distance than a conventional portable light fixture made of white light in a firey smoke situation. The difference in visible distance between the red light and the white light has been described in detail in the foregoing, and will be briefly described.

Light scattering due to fine particles in the air is an optical law that is revealed by the Rayleigh scattering law that the shorter the light wavelength is, the larger the light transmittance is, the smaller the light transmittance is.

That is, according to the present invention, the red LED emergency lighting lamp 241 is automatically turned on when a fire is detected, or the red LED emergency lighting lamp 241 can be outputted according to manual operation of the user, thereby enhancing convenience of daily life .

The smoke and flue gas cleaning step (S50) is a step for the controller 230 to purify the noxious gas and / or the smoke. That is, the present invention purifies smoke or gas by an anion to prevent smoke and smoke gas from suffocating during a fire, and supplies purified air to the user. Accordingly, the user can suck smoke or noxious air by the negative ion generator 222 when a fire occurs, and there is no risk of suffocation.

In addition, since the structure of the negative ion generator 222 is formed in a cone shape whose diameter increases from the lower side toward the upper side, the venturi effect is implemented to change the air pressure inside the housing 100, It is not necessary to provide a separate air suction device (for example, a fan). The present invention can provide a portable disaster rescue device having a built-in air purifying function so as not to feel a weight feeling even if it is worn at a position close to the user's respiratory organs.
