Description

[0001] The present invention relates to a method and apparatus for disposing a safety tool in a disaster situation,

The present invention is a technique for informing the position of a safety device (for example, a fire extinguisher, an oxygen mask) to prevent secondary damage in a shaded area due to a disaster situation. More particularly, the present invention relates to a method of attaching a patch to a safety tool by generating power from ambient energy (e.g., light energy, thermal energy) without a separate power supply means, In a recognizable form (e.g., voice alarm, light source blinking).

As buildings and facilities become increasingly complex, the likelihood of accidents (such as fire accidents) increasingly leads to major accidents. Especially in places like subway stations, safety tools (eg fire extinguishers, oxygen masks) are provided. However, if a disaster occurs, electricity will be blocked and the region will be in a shaded state where it is difficult to obtain visibility. There is no such thing to find.

In this way, in areas where a disaster occurs, the area is exposed to a situation where large-scale second-person casualties may occur independently of the accident.

In addition, even if a fire occurs in the building, even if the interior of the building is shaded by smoke and flames, safety tools such as an oxygen mask and a fire extinguisher are provided in the surrounding area. However, There is also a problem that damage occurs.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is an exemplary view showing a state in which a patch device according to the present invention is attached to a safety tool. Referring to FIG. 1, a patch device 100 according to the present invention is attached to a safety tool (e.g., an oxygen mask, a fire extinguisher S) in a patch type. The patch device 100 attached to the safety tool S may be configured to obtain electrical energy through energy harvesting that occurs normally at the periphery.

Here, energy harvesting is a technique for acquiring electrical energy from an energy source that is generated in daily life, such as vibration, human motion, light, heat, electromagnetic waves, and the like.

The principle of converting the environmental energy of this environment to electric energy is generally known. If the temperature is different at both terminals of the closed circuit, the current flows to the closed circuit, or the electricity is generated when the external pressure is applied Piezoelectric effect, and the like.

On the other hand, the safety tool S means various safety equipment including an oxygen mask and a fire extinguisher as equipment for helping a person to maintain safety in a disaster such as a fire.

FIG. 2 is a block diagram of a non-power-source patch device for reporting the position of a safety tool in a disaster situation according to the present invention. 2, the patch device 100 according to the present invention is a non-power source patch device attached to the safety tool S as a patch type to inform the outside of the position of the safety tool in a disaster situation, A control unit 120, and a display unit 130.

First, the sensing power source unit 110 generates power from ambient energy (e.g., light energy, thermal energy, vibration energy) in a non-power source state without a separate power supply means. The generated power is supplied to the control unit 120 and the display unit 130 to operate the control unit 120 and the display unit 130.

As described above, the sensing power source unit 110 generates electric energy from the surrounding energy without using a separate power supply means, so that the sensing power source unit 110 can be used without an expiration date unless the patch device 100 itself is broken. Also, since the sensing power source unit 110 determines the disaster situation from the electric energy generated to obtain the operation power, there is an advantage that the maintenance for the failure is sure.

The sensing power source unit 110 includes a solar module 111 for converting solar light energy into electrical energy and a thermal circuit for generating electrical energy according to the Seebeck effect by constructing a closed circuit formed by different metal junctions. And an element module 112. [0033]

The sensing power supply unit 110 may further include an environment sensing module 113 for collecting information on external environmental factors such as temperature, humidity, gas, vibration and the like and assisting the user in finely determining a disaster situation .

Meanwhile, the sensing power source unit 110 may further include a gas sensing module (not shown) for sensing noxious gas around the patch device 100. Here, the determination unit 122 of the control unit 120 determines that the hazardous gas is detected in response to the noxious gas detected by the gas sensing module, and the signal processing unit 123 identifies the disaster situation, As shown in FIG.

The controller 120 receives electrical energy from the sensing power unit 110 and uses the received electrical energy as an operating power. In addition, the control unit 120 identifies the surrounding disaster state based on the variation of the energy level received from the sensing power source unit 110, and controls the disaster state output mode according to the disaster state identification result. The control unit 120 for performing such a process includes a calculation unit 121, a determination unit 122, a signal processing unit 123, and a display processing unit 124.

First, the calculation unit 121 calculates the amount of energy from the operation power source obtained by the sensing power source unit 110 from surrounding environmental energy, and checks whether the energy level is within a predetermined normal range. That is, when the sensing power source unit 110 normally generates the electric energy from the ambient environment energy and supplies the electric energy to the control unit 120 in the normal range, in a disaster situation where the fire or other sudden temperature rises, The amount of energy to be supplied to the control unit 120 also increases sharply.

The calculation unit 121 calculates the amount of energy generated by the sensing power source unit 110 and checks whether the energy level has exceeded a critical point beyond a normal range at a specific time point at which the energy level suddenly changes.

The determination unit 122 determines that the energy level calculated through the calculation unit 121 is suddenly increased at a specific time point and exceeds a predetermined critical point that is set as a normal range and determines that the disaster situation is a situation. The disaster situation judgment based on the energy level will be described later in detail with reference to Fig.

The signal processing unit 123 identifies the disaster situation determined by the determination unit 122 and informs the display processing unit 124 of the disaster situation identification result.

The display processing unit 124 controls the disaster state output mode in response to the disaster state identification result by the signal processing unit 123 and outputs the disaster state output mode through the display unit 130 in an externally recognizable format.

The display unit 130 may include at least one of a speaker 131 for outputting a voice alarm and a light emitting unit 132 for outputting blinking light blinking. (E.g., voice alarm, light source blinking) in an externally recognizable form corresponding to the disaster state output mode of the display processing unit 124. [

FIG. 3 is a graph illustrating a process of detecting a disaster by calculating energy of a power source provided from a sensing power source according to an embodiment of the present invention. A process of detecting a disaster situation by the control unit will be described with reference to FIG.

First, when the sensing power source unit 110 generates electric energy (power) from the surrounding energy and supplies it to the control unit 120, the calculation unit 121 of the control unit 120 calculates the energy level. The amount of energy provided to the control unit 120 by the sensing power source unit 110 is calculated to set the energy range lower than the " critical upper limit " and the "critical lower limit"

At this time, the threshold upper limit and the threshold lower limit may be set in advance or may be adaptively set in consideration of a difference in energy generation level of the installation environment. Although it is preferable to set both the upper limit threshold and the lower threshold limit, it is also possible to configure only the upper limit threshold.

When the sensing power source unit 110 generates electric energy from the ambient energy and supplies the generated electric energy to the control unit 120, the calculation unit 121 of the control unit 120 calculates the size of the electric energy with time ]. If the magnitude of the energy thus calculated exceeds the " critical upper limit "at the specific time point t1 and deviates from the normal range, the determination unit 122 identifies" disaster situation detection "

On the other hand, when the energy level calculated by the calculation unit 121 falls below the "critical lower limit ", the sensing power supply unit 110 may be in an aged state such that it is difficult to generate electric energy smoothly from the surrounding energy. 122 may determine that the patch device 100 is being replaced.

If the determination unit 122 determines that it is a replacement time, the signal processing unit 123 identifies it and notifies the display processing unit 124 of the result of the identification, and the display processing unit 124 displays, on the display unit 130, The output mode can be controlled so as to emit light in a color (e.g., red light).

4 is a flowchart illustrating a process of informing the position of a safety tool using a non-power supply patch in a disaster situation such as a fire according to the present invention. Referring to FIG. 4, the location notification process of the safety tool using the non-power supply patch in a disaster situation according to the present invention will be described in detail.

S110: a sensing power supply unit 110 is mounted on the patch device 100 attached to the safety device S and the sensing power supply unit 110 is connected to the safety device S in a non-powered state without any external power supply means And generates electric energy (power) from the energy and provides it to the control unit 120 and the display unit 130.

S120 and S130: The control unit 120 and the display unit 130 are operated by the electric energy (power) supplied from the sensing power unit 110 so that the light source is kept lit in the light emitting unit 132 of the display unit 130 .

The calculation unit 121 of the control unit 120 calculates the energy amount of the power supplied from the sensing power source unit 110 and checks whether the energy level is within the normal range within the critical point as usual.

S140: In the vicinity of the safety tool S with the patch device 100, for example, when a fire occurs, the neighborhood is very bright and the temperature difference increases, and accordingly, the amount of electric energy generated through the sensing power source unit 110 increases rapidly do. At this time, the power supplied from the sensing power source unit 110 by the control unit 120 also increases sharply. When the calculation unit 121 calculates such a suddenly increasing amount of energy, the energy magnitude exceeds a critical point at a specific time point, unlike usual.

S150: On the other hand, if the engine level does not deviate from the normal range, it is determined that a disaster situation has not occurred, and the display processing unit 124 controls the display unit 130 to display a normal state. For example, a steady state can be indicated by a steady green LED or blinking slowly.

S160: The determination unit 122 identifies that the energy level calculated by the calculation unit 121 exceeds a critical point at a specific point in time, and determines the current state of the region as a disaster state.

S170, S180, and S190: The signal processing unit 123 then identifies the disaster situation determined by the determination unit 122 and informs the display processing unit 124 of the disaster situation identification result. The display processing unit 124 controls the disaster state output mode in response to the disaster state identification result. The display unit 130 displays an event (e.g., voice alarm, Light source blinking).

Through the above process, people in the vicinity of the disaster can easily recognize intuitively the location of the safety tool with the patch device 100 through the patch device 100 even in the shadowed area. Therefore, It is possible to prevent damage to the second person from the situation.
