In an extreme environment such as a disaster, such as in the sea, under water, underground, or in an enclosed space, the communication signal is weak and the communication with the ground is often disconnected. In particular, if the ship sinks into the sea as the sun sinks into the sea, it is possible to collect the situation of the survivors on board and the room environment through sensors. However, even in case of communication impossible, there is no way to transmit the control system to the control system, There are many difficulties in structure.

Conventional sensors can be used for long distance communications such as 3G and LTE, Radio Frequency Identification (RFID), Near Field Communication (NFC), WiFi, Bluetooth, Global System for Mobile communications (GSM) And so on. However, it is difficult to transmit the sensor information using the conventional communication method in a place where wired installation is impossible and in an extreme environment where wireless communication is difficult.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise.

Also, the terms of " part ", "... module" in the description mean units for processing at least one function or operation, which may be implemented by hardware or software or a combination of hardware and software.

Hereinafter, a black box, a monitoring device, and a physical signal transmission method according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a network configuration diagram according to an embodiment of the present invention. FIG. 2 illustrates a physical signal transmission item according to an embodiment of the present invention. FIG. FIG. 4 is a diagram illustrating a configuration of a physical signal according to an embodiment of the present invention, and FIG. 5 is a diagram illustrating an example of a configuration of a physical signal according to another embodiment of the present invention.

Referring to FIG. 1, one or more black boxes 100 communicate with a monitoring device 200. One or more of the black box 100 and the monitoring device 200 are basically capable of wired / wireless communication, and perform communication using a physical signal when wired / wireless communication is impossible.

Here, the physical signal is a signal having a specific wavelength or a specific frequency, and may be an acoustic wave signal in an audible frequency band or an ultrasonic wave band, a vibration signal, or an optical signal.

The at least one black box 100 includes a plurality of sensors, monitors the surrounding environment, generates sensed values, and transmits the sensed values to the monitoring device 200 through a physical signal. One or more black boxes 100 can only be used for wired / wireless communication at normal times, and can be switched to physical signal communication when a disaster situation in which wired / wireless communication becomes impossible.

At this time, the one or more black boxes 100 and the monitoring device 200 communicate within a position where transmission and reception of physical signals are possible, for example, within 20 m. For example, it is possible to detect sound waves or vibrations, or to communicate at a distance such that the optical signal can be identified.

At least one black box 100 normally charges the emergency battery through a constant power source. When the reference value of the information received through the impact sensor, the gyro sensor, and the heat sensor is exceeded, it is recognized as a disaster situation and a sensed value is generated that measures the surrounding environment including temperature, humidity, oxygen, carbon dioxide, and flood information. And transmits the sensing value to the monitoring device 200 through a physical signal.

Here, when one or more black boxes 100 recognize a disaster situation, power is supplied through the emergency battery and the other black box 100 waits when the other black box 100 is transmitting a physical signal. Then, it is determined whether another black box 100 is operating, so that any black box 100 transmits a physical signal when it does not transmit a physical signal, so that one or more black boxes 100 sequentially operate.

The monitoring device 200 analyzes the physical signals sequentially received from one or more black boxes 100 to extract sensing values and monitors the surrounding environment of the location where one or more black boxes 100 are installed based on the sensed sensing values do.

As described above, the at least one black box 100 can continuously transmit the disaster situation by expressing the sensed value measuring the surrounding environment in a state where the disaster situation is generated, as a physical signal, so that it is possible to measure and transmit the surrounding environment information in case of a disaster It has features that work in extreme environments.

The items of transmission of physical signals transmitted by one or more black boxes 100 are shown in FIG.

Referring to FIG. 2 (a), the physical signal transmission item includes object identification information P1, a plurality of different sensing items, and respective sensing values P3 corresponding to the sensing items.

Here, the object identification information P1 may indicate the position information of the black box 100 as information for identifying the black box 100 installed at a plurality of different positions as shown in FIG. At this time, the black box 100 is installed at different positions requiring sensing, for example, a ship, a building underground, or the like.

The object identification information P1 may be a decimal number ranging from 1 to 50.

The sensing items correspond to sensor types, which may include temperature items, carbon dioxide items, oxygen items, motion detection items, and immersion items. The sensing item identification information for identifying the sensing item is assigned to the sensing item, and the identification number can be given in the form of a decimal number. For example, a 100-digit identification number can be assigned to 100 for the temperature item, 101 for the carbon dioxide concentration item, 102 for the oxygen concentration item, 103 for the motion sensing item, and 104 for the immersion item.

The sensing value is used as the sensing value collected by each of the plurality of sensors, and the sensing value is in the form of a decimal number.

Referring to FIG. 2 (b), each segment is represented by a decimal number. That is, the object identification information is 2, the temperature sensing item is 100, and the temperature value is 15.

Referring to FIG. 2 (c), each segment expressed in decimal numbers is converted into binary numbers. That is, the object identification information '2' is represented by binary number '10'. And the temperature item '100' is represented by a binary number '0 1 1 0 0 1 0 0'. And the temperature sensing value '15' is represented by a binary number '1 1 1 1'.

As such, all decimal types of transmission items are represented by binary numbers, ie, '0' and '1'. Accordingly, if the physical signal can be divided into '0' and '1', information that the black box 100 senses can be transmitted in the form of a physical signal. This is shown in Table 1.

Item Object identification information Sensing items Sensing value Decimal number 2 100 Actual value (15 degrees) Binary number 0010 01100100 1111 Physical signal It is divided into wavelength, frequency, light color, or 0 or 1 to a specific wavelength, frequency.

As shown in Table 1, the object identification information, the sensing item, and the sensing value are all composed of decimal numbers, which can be converted into binary numbers of 0 and 1. And 0, 1 can be divided into wavelength, frequency, and color of debt. In the case of light, you can identify the 0 and 1 using the color. For example, 0 can identify a blue light source, and 1 can identify a yellow light source.

Further, 0 or 1 can be distinguished by using a specific wavelength or a specific frequency. A method of dividing 0 and 1 using characteristics of wavelength and frequency will be described with reference to FIGS. 4 and 5. FIG.

First, referring to FIG. 4, 0 and 1 are separated using wavelengths. That is, a first wavelength having a specific length is assigned to binary number 0, and a second wavelength longer or shorter than the first wavelength may be assigned to binary number 1.

)의 2배 ~ 3배에 해당하는 긴 파장(

2 ~ 3)으로 0과 1을 구분하여 서로 중복되지 않도록 한다. To be able to distinguish arbitrary wavelengths, a short wavelength (

) And a short wavelength (

Long wavelength corresponding to 2 to 3 times of

2 ~ 3), so that they do not overlap with each other.

At this time, as shown in FIG. 4A, a short wavelength may be set to 0, a long wavelength may be set to 1, and a long wavelength may be set to 0 and a short wavelength to 1, as shown in FIG. 4B.

In the case of using such a wavelength, the binary type transmission item described in FIG. 2 is a physical signal in which a long wavelength and a short wavelength are continuous. That is, the binary number 100 is expressed as a continuous physical signal of "long wavelength -> short wavelength -> short wavelength" defined in FIG. 4 (a).

In addition, referring to FIG. 5, 0 and 1 are distinguished by using frequencies. That is, a first frequency having a specific size is assigned to binary number 0, and a second frequency having a size larger or smaller than the reference value set for the first frequency may be assigned to binary number 1.

For easy identification of arbitrary frequencies

The frequency type is used for classification. In this case, as shown in FIG. 5 (a), the low frequency is divided into 0 and the high frequency is divided into 1, or the low frequency is defined as 1 and the high frequency is 0 as shown in FIG. In the case of using such a frequency, the binary type transmission item described above with reference to FIG. 2 is a physical signal in which high frequency and low frequency are continuous. That is, the binary number 100 is expressed as a continuous physical signal of 'high frequency -> low frequency -> low frequency' defined in (a) of FIG.

The configuration of the black box 100 employing the physical signal transmission method described so far is the same as that of FIG.

FIG. 6 is a block diagram showing a detailed configuration of a black box according to an embodiment of the present invention, and FIG. 7 shows a plurality of sensors of FIG.

6, the black box 100 includes a plurality of sensors 110, a display unit 120, a storage unit 130, a processor 140, a physical signal transmission unit 150, a physical signal sensing unit 160, A wire / wireless communication unit 170, and a power supply unit 180.

The plurality of sensors 110 measure the surrounding environment to generate a sensing value. The plurality of sensors 110 may be configured as shown in FIG.

Referring to FIG. 7, the plurality of sensors 110 are divided into a sensor unit 111 for determining a disaster and a general sensor unit 113 including a general sensor.

The sensor unit 111 for determining a disaster includes a shock sensor 111-1 for detecting an impact, a tilt sensor 111-3 for sensing a tilt of the black box 100, Temperature sensor 111-5 for detecting a high temperature, but any other sensor for determining a disaster may be added.

The general sensor unit 113 is constituted by the most basic sensor serving to monitor and transmit the environment to the disaster area in the event of a disaster. For example, a temperature sensor 113-1 for sensing the ambient temperature, a flood sensor 113-3, a motion sensor 113-5 and a carbon dioxide sensor 113-7. Any sensor that can be configured can be added.

Referring again to FIG. 6, the display unit 120 displays the battery charging status of the black box 100 on the screen.

The storage unit 130 is connected to the processor 140 and stores various information for driving the processor 140. The storage unit 130 may be implemented as a medium such as a dynamic random access memory (DRAM), a RAM bus DRAM, a synchronous DRAM, a static random access memory (RAM), or the like. The storage 130 may be internal or external to the processor 140 and may be coupled to the processor 140 in a variety of well known ways.

In this case, the storage unit 130 stores information necessary for generating a physical signal. A first wavelength having a specific length is assigned to a binary number 0, and a second wavelength shorter or longer than a predetermined reference value with respect to the first wavelength is a binary number 1 Lt; / RTI > Also, a first frequency having a specific size may be assigned to binary number 0, and a second frequency having a size larger or smaller than a predetermined reference value with respect to the first frequency may be allocated to binary number 1. Also, it can store physical signal transmission information, which is divided into light color, sound and silence, vibration and non-vibration.

The processor 140 may be implemented as a central processing unit (CPU) or other chipset, microprocessor, or the like. The processor 140 includes a conversion unit 141, a physical signal generation unit 143, and a control unit 145.

The converting unit 141 collects sensing values from each of the plurality of sensors 110. As described in FIGS. 1 to 5, the sensing value in the decimal form is converted into a binary number.

The physical signal generation unit 143 receives the sensing value converted into binary from the conversion unit 141 and generates a sensing value converted into a binary number using the mapping information stored in the storage unit 130 as a physical signal. That is, the first wavelength and the second wavelength are generated as a continuous physical signal, or the first frequency and the second frequency are generated as a continuous physical signal.

The physical signal generation unit 143 generates the physical layer signal of FIG.

The physical signal generation unit 143 may generate a physical signal indicating the existence of an emergency according to a request from the control unit 145 when the control unit 145 determines the emergency disaster situation. Here, the physical signal indicating whether or not to survive indicates that viability and survival are different from each other in a light source color, or is represented by silence and voices, or by non-vibration or vibration.

The control unit 145 collects sensing information of the temperature, the concentration of oxygen, the degree of immersion, and the illuminance sensor (motion presence or absence), and determines whether or not the sensor can survive based on the sensing information. The possibility of the survival condition can be changed according to the change of the sensing information of FIG.

The physical signal generation unit 143 only determines whether the basic person is alive or not in the case of transmission of sensing information due to a failure of the communication network in the event of a disaster, and transmits the physical signal to the outside.

First, it can be divided into the color of light, which can be defined as red if the survival condition is poor, and blue if the survival condition is viable.

In addition, it can be defined as sound, which can be defined as silence if the survival condition is poor, and sound if it is possible to survive.

In addition, it can be classified into vibration. If the survival condition is poor, it can be defined as vibrationless, and if it can survive, it can be defined as vibration.

If it is determined that the disaster situation is based on the sensed values collected through one or more disaster detection sensors 111-1, the controller 145 generates physical signals including sensed values collected through one or more general sensors 11-3 And controls the physical signal generation unit 143 and the physical signal sensing unit 160 to generate the physical signal.

If the signal is already generated in the other device (black box) at this time, the controller 145 waits for a predetermined time in the waiting state in order to prevent the occurrence of the duplicate signal. After that, the signal transmission is retried again.

The physical signal transmitting unit 150 is a physical means for actually generating the physical signal generated by the physical signal generating unit 143.

For example, a vibration generator, an acoustic emission sensor, an accelerometer, an LED or a light source using a laser. In addition, the generated sound wave may be an audio frequency band, or a sound file having a frequency band outside the audio frequency band such as an ultrasonic wave.

The physical signal transmitting unit 150 generates a predefined frequency generated by the physical signal generating unit 143 or a physical signal having a predefined wavelength. In addition, it can generate silence or sound. Further, it is possible to cause no vibration or vibration. In addition, a light source of a specific color can be generated.

The physical signal sensing unit 160 can measure vibration using an acoustic emission sensor or an accelerometer, can sense light using an optical sensor, can be a sound wave sensor, a vibration sensor, or a microphone. In this case, when a physical signal (sound or sound) is sensed, a microphone capable of confirming when another device signal is generated is installed, and the apparatus is stopped and waits for a predetermined time to prevent duplication of physical signals in a plurality of black boxes 100 do.
