Description

BLAKBOX, MONITORING APPARATUS AND METHOD FOR TEANSMITTING PHISICAL SIGNAL

The present invention relates to a black box, a monitoring device, and a method for transmitting a physical signal.

In extreme environments such as disasters, that is, in the sea, in water, underground, in an enclosed space, etc., the communication signal is weak and communication with the ground is often interrupted. In particular, in the case of a ship sinking in the sea, such as the sinking of the Sewol ferry, it is possible to collect the status of survivors and the cabin environment through the sensor, but in an environment where communication is not possible, there is no way to transmit the collected sensing information to the control system, There are many difficulties in the structure.

Traditional sensors start with short-range communication using RF (Radio Frequency) technology, followed by long-distance communication such as 3G and LTE, RFID (Radio Frequency Identifcation), NFC (Near Field Communication), WiFi, Bluetooth, and GSM (Global System for Mobile communications). Various network technologies are being applied. However, it is difficult to transmit sensor information using such an existing communication method in a place where wired installation is impossible and in an extreme environment where wireless communication is difficult. In particular, in most disaster situations, disconnection from the external environment occurs in many cases, so there is no way to contact the outside in such an environment. In the case of sensors for information acquisition, the reality is that no matter how many sensors are installed, the acquired information cannot be transmitted to the outside.

Although there is a conventional method of transmitting information using Morse code, there is a difficulty in decoding the Morse code because it is not a structure that can be easily used by everyone.

In addition, if it is a special case of a disaster situation to promptly transmit all information within a short period of time requiring urgency, Morse code is not suitable for a disaster situation because there are many contents of the same information even if it is the same.

In the case of not a disaster situation, the display device may further include a wired/wireless communication unit configured to transmit black box information including the black box identification information, the one or more different sensing values, and battery state information through a wired/wireless communication network.

In addition, in terms of transmitting or receiving a physical signal, anyone without specialized knowledge can easily identify information, so it is the most efficient method of transmitting information.

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.

1 is a network configuration diagram according to an embodiment of the present invention, FIG. 2 shows a physical signal transmission item according to an embodiment of the present invention, and FIG. 3 is an installation of one or more black boxes according to an embodiment of the present invention It is a layout diagram, and FIG. 4 is an exemplary diagram of a physical signal configuration according to an embodiment of the present invention, and FIG. 5 is an exemplary diagram of a physical signal configuration according to another embodiment of the present invention.

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

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

The one or more black boxes 100 are provided with a plurality of sensors to generate a sensed value measured by monitoring the surrounding environment, and transmit it to the monitoring device 200 through a physical signal. The one or more black boxes 100 are normally capable of only wired and wireless communication, and in a disaster situation in which wired and wireless communication becomes impossible, they may be switched to physical signal communication.

In this case, the one or more black boxes 100 and the monitoring device 200 communicate within a location where transmission and reception of physical signals are possible, for example, within 20 m. For example, sound waves or vibrations can be detected, or optical signals can be communicated at a distance that can be discerned.

One or more black boxes 100 normally charge an emergency battery through regular power. And when the reference value of the information received through the shock sensor, the gyro sensor, and the thermal sensor is exceeded, it is recognized as a disaster situation and a sensing value is generated that measures the surrounding environment including temperature, humidity, oxygen, carbon dioxide, and flood information. Then, the sensed value is transmitted to the monitoring device 200 through a physical signal.

Here, when a disaster situation is recognized, the one or more black boxes 100 are supplied with power through an emergency battery and wait while the other black boxes 100 are transmitting physical signals. And again, it is determined whether another black box 100 is operating, and when neither black box 100 transmits a physical signal, a physical signal is transmitted, and eventually one or more black boxes 100 are sequentially operated.

The monitoring device 200 extracts a sensed value by analyzing the physical signals sequentially received from the one or more black boxes 100 , and monitors the surrounding environment of the location where the one or more black boxes 100 are installed based on the extracted sensed values. do.

As such, the one or more black boxes 100 can continuously transmit the disaster situation by expressing the sensed value measured by the surrounding environment as a physical signal in a state where a disaster situation occurs, so that information about the surrounding environment can be measured and transmitted in case of a disaster. It has the characteristics of being able to operate even in extreme environments.

Meanwhile, a transmission item of a physical signal transmitted by one or more black boxes 100 is shown in FIG. 2 .

Referring to FIG. 2A , the physical signal transmission item includes object identification information P1 and a plurality of different sensing items and each sensing value P3 corresponding to each sensing item.

Here, the object identification information P1 is information for identifying the black box 100 installed in a plurality of different locations, respectively, as shown in FIG. 3 , and may indicate location information of the black box 100 . At this time, the black box 100 is installed in different locations that require sensing, for example, may be a ship, a building basement, or the like.

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

The sensing item corresponds to the sensor type, and may include a temperature item, a carbon dioxide item, an oxygen item, a motion detection item, and a submersion item. In addition, sensing item identification information for identifying the sensing item is allocated to the sensing item, and an identification number may be assigned in the form of a decimal number. For example, the 100th identification number may be assigned to the temperature item as 100, the carbon dioxide concentration item as 101, the oxygen concentration item as 102, the motion detection item as 103, the submersion item as 104, and the like.

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

Referring to (b) of FIG. 2, each transmission item is all expressed in decimal numbers. That is, the object identification information is 2, the temperature sensing item is 100, and the temperature value is 15.

Referring to (c) of FIG. 2, each transmission item expressed as a decimal number is all converted into a binary number. That is, the object identification information '2' is expressed as a binary number '1 0'. And the temperature item '100' is expressed as a binary number '0 1 1 0 0 1 0 0'. And the temperature sensing value '15' is expressed as a binary number '1 1 1 1'.

As such, all transmission items in decimal form are expressed in binary numbers, that is, both '0' and '1'. Accordingly, if the physical signal can be divided into '0' and '1', information sensed by the black box 100 in the form of a physical signal can be transmitted. Table 1 shows this.

Item object identification information sensing item sensed value decimal 2 100 Actual value (15 degrees) binary 0010 01100100 1111 physical signal Differentiate by wavelength, frequency, or color of light, or map 0s and 1s to specific wavelengths and frequencies

As shown in Table 1, object identification information, sensing items, and sensing values are all composed of decimal numbers, which can be converted into binary numbers of 0 and 1. And 0 and 1 can be distinguished by wavelength, frequency, and color of the field. In the case of light, 0 and 1 can be distinguished using color. For example, 0 is a blue light source and 1 is a yellow light source.

Also, 0 and 1 may be distinguished using a specific wavelength or a specific frequency. A method of distinguishing 0 and 1 using the characteristics of wavelength and frequency will be described with reference to FIGS. 4 and 5 .

First, referring to FIG. 4 , it is an embodiment in which 0 and 1 are distinguished using wavelengths. That is, a first wavelength having a specific length may be allocated to binary 0, and a second wavelength longer or shorter than the first wavelength by a predetermined reference value may be allocated to binary 1.

2 ~ 3)으로 0과 1을 구분하여 서로 중복되지 않도록 한다. Short wavelength (

) and short wavelengths (

) of 2 to 3 times longer wavelength (

2 ~ 3) to separate 0 and 1 so that they do not overlap each other.

In this case, the short wavelength may be 0 and the long wavelength 1 as in FIG. 4(a), or the long wavelength may be 0 and the short wavelength 1 as in FIG. 4(b).

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

Also, referring to FIG. 5 , it is an embodiment in which 0 and 1 are distinguished using a frequency. That is, a first frequency having a specific magnitude may be allocated to binary 0, and a second frequency having a magnitude greater than or smaller than a predetermined reference value than the first frequency may be allocated to binary 1.

To make it easier to distinguish between arbitrary frequencies

It is distinguished using the shape of the frequency during the period. At this time, as shown in Fig. 5 (a), the low frequency is divided into 0 and the high frequency is 1, or as shown in Fig. 5 (b), the low frequency is divided into 1 and the high frequency is defined as not overlapping each other. In the case of using such a frequency, the transmission item in the form of a binary number described above with reference to FIG. 2 becomes a physical signal form in which high and low frequencies are continuous. That is, the binary number 100 is expressed as a physical signal in which 'high frequency -> low frequency -> low frequency' defined in (a) of FIG. 5 is continuous.

The configuration of the black box 100 employing the physical signal transmission method described so far is shown in FIG. 6 .

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 .

Referring to 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 , and a physical signal detection unit 160 . , a wired/wireless communication unit 170 and a power supply unit 180 .

The plurality of sensors 110 measure the surrounding environment to generate a sensed value. The plurality of sensors 110 may be configured as shown in FIG. 7 .

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

The sensor unit 111 for determining a disaster is a sensor for determining a disaster situation, and includes an impact sensor 111-1 for detecting an impact, and a tilt sensor 111-3 for detecting the degree of inclination of the black box 100 . , a high temperature sensor 111-5 for detecting a high temperature is included as a default, but any sensor for determining a disaster may be added in addition to it.

The general sensor unit 113 is composed of the most basic sensor that serves to monitor and transmit the environment for the disaster area in a disaster situation. For example, it includes a temperature sensor 113-1 for detecting the ambient temperature, a water immersion sensor 113-3, a motion detection sensor 113-5, and a carbon dioxide sensor 113-7, and in addition to monitoring the environment. Any available sensor can be added and configured.

Again, referring to FIG. 6 , the display unit 120 displays the battery charge state 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 in a medium such as a RAM such as a dynamic random access memory (DRAM), a RAM bus DRAM, a synchronous DRAM, or a static RAM. In addition, the storage unit 130 may be inside or outside the processor 140 , and may be connected to the processor 140 by various well-known means.

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 binary 0, and a second wavelength longer or shorter than a predetermined reference value compared to the first wavelength is binary 1. It is possible to store mapping information assigned to . Also, it is possible to store mapping information in which a first frequency having a specific magnitude is allocated to binary 0, and a second frequency having a magnitude greater or smaller than a predetermined reference value compared to the first frequency is allocated to binary 1. Also, it is possible to store physical signal transmission information divided into color of light, sound and silence, and vibration and non-vibration.

The processor 140 may be implemented as a central processing unit (CPU) or other chipsets, microprocessors, and the like. The processor 140 includes a converter 141 , a physical signal generator 143 , and a controller 145 .

The converter 141 collects sensed values from each of the plurality of sensors 110 . And, as described with reference to FIGS. 1 to 5 , the sensed value in the decimal form is converted into a binary number.

The physical signal generating unit 143 receives the sensing value converted into a binary number from the converting unit 141 , and generates the sensed value converted into a binary number as a physical signal by using the mapping information stored in the storage unit 130 . 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 generator 143 generates the transmission item of FIG. 2 as a physical signal.

When the controller 145 determines an emergency disaster situation, the physical signal generator 143 may generate a physical signal indicating whether or not the controller 145 is alive at the request of the controller 145 . Here, the physical signal indicating whether or not survival is indicated by different light source colors or by silent and sound, or by non-vibration or vibration, respectively, indicating survivability and poor survival.

The control unit 145 collects sensing information of temperature, oxygen concentration, immersion, and illuminance sensor (movement), and determines whether survival is possible based on the above sensing information. Depending on the change of sensing information of the patient, the availability of survival conditions may vary.

The physical signal generator 143 transmits a physical signal to the outside by determining whether the most basic person is alive or a survival condition is met when transmission of sensing information is impossible due to a communication network failure in the event of a disaster.

First, it can be distinguished by the color of light. If the survival conditions are poor, it can be defined as red, and when the conditions are viable, it can be defined as blue.

Also, it can be classified by sound. If the survival condition is poor, it can be defined as silent, and when the condition for survival is possible, it can be defined as sound sound.

In addition, it can be divided into vibration. If the survival condition is poor, it can be defined as no vibration, and if the survival condition is possible, it can be defined as vibration.

When it is determined that the disaster situation is a disaster based on the sensed values collected through the one or more disaster detection sensors 111-1, the control unit 145 transmits a physical signal including the sensed values collected through the one or more general sensors 11-3. The physical signal generating unit 143 and the physical signal detecting unit 160 are controlled to generate them.

At this time, if another device (black box) is already generating a signal, the control unit 145 waits for a predetermined time in the standby state first in order to prevent the occurrence of a duplicate signal. After that, try to transmit the signal 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 . It may be any one of a sound wave generator that generates sound waves having a specific frequency or wavelength, a vibration generator that generates vibrations having a specific frequency or wavelength, and a light source that generates light having a specific frequency or wavelength. Examples include vibration generators, acoustic emission sensors, accelerometers, and light sources using LEDs or lasers. In addition, the generated sound wave may be an audible frequency band or a sound wave having a frequency band outside the audible frequency band, such as ultrasound.

The physical signal transmission unit 150 generates a physical signal in which a predetermined frequency or a predetermined wavelength generated by the physical signal generation unit 143 is continuous. In addition, it is possible to generate a silent or sound sound. In addition, it can generate vibration-free or vibration. In addition, a light source of a specific color can be generated.

The physical signal transmission unit 150 serves to transmit information such as temperature, water immersion, carbon dioxide concentration, and motion detection collected by the general sensor unit 113 through physical signals such as vibration, sound, light and other various methods. .

The physical signal detection unit 160 detects a physical signal from the surrounding black box 100 . The physical signal sensing unit 160 may measure vibration using an acoustic emission sensor or an accelerometer, may detect light using an optical sensor, may be a sound wave sensor, a vibration sensor, or may be a microphone. At this time, a microphone that can be checked when a signal from another device is generated is installed by default, so when a physical signal (sound, sound wave) is detected, the device stops operating and waits for a certain time to prevent the physical signal from being duplicated in multiple black boxes 100 do.

The wired/wireless communication unit 170 is connected to the processor 150 and transmits data received through a network (not shown) to the processor 150 , and transmits data output by the processor 150 to a network (not shown). At this time, it is connected to the monitoring device 200 through a network (not shown). The wired/wireless communication unit 170 may include a baseband circuit for processing a signal.

The power supply unit 180 receives external power or power from an internal battery to supply power required for operation of each component. The power supply unit 180 includes a power control unit 181 and a battery 183 . The power control unit 181 receives power from an external power source and supplies power to each component of the black box 100 . In addition, the black box 100 may be driven with the power charged in the battery 183 in an emergency by charging the battery 183 with power. The battery 183 is not easily detached, and it is preferable to place it in a position where it is not easily determined whether or not it is mounted. In normal times, power is supplied to the battery 183 to always maintain a fully charged state, and the charging state of the battery 183 can be displayed through the display unit 120 .

8 is a block diagram illustrating a detailed configuration of a monitoring device according to an embodiment of the present invention.

Referring to FIG. 8 , the monitoring device 200 includes a physical signal detection unit 210 , a physical signal analysis unit 220 , a storage unit 230 , a wired/wireless communication unit 240 , a control unit 250 , and a display unit 260 . include

The physical signal detection unit 210 detects a physical signal transmitted by one or more black boxes 100 , and the configuration is the same as that of the physical signal detection unit 160 of FIG. 6 . For example, it may be a sound wave sensor, a vibration sensor, or a microphone.

The physical signal detection unit 210 detects a physical signal having a predetermined frequency or a predetermined wavelength continuous from one or more black boxes 100 . For example, it may be a microphone, but is not limited thereto, and any sensor capable of detecting a physical signal such as vibration or wavelength may be used.

The physical signal analysis unit 220 interprets the physical signal based on the mapping information stored in the storage unit 230 to extract binary object identification information, sensing items, and sensing values, and thus extracted object identification information, sensing items and Converts the sensed value to decimal. Then, as shown in (b) of FIG. 2 , the object identification information, the sensing item, and the sensing value may be represented as sequentially listed information.

The storage unit 230 stores the same mapping information as the mapping information stored in the black box 100 . And information and programs necessary for the operation of the monitoring device 200 are stored.

The storage unit 230 stores black box identification information, sequence information of one or more different sensing values, and binary information assigned to a frequency or wavelength. The binary information may include mapping information in which a first wavelength having a specific length is allocated to binary 0, and a second wavelength longer or shorter than the first wavelength is allocated to binary 1. Alternatively, the mapping information may include mapping information in which a first frequency having a specific magnitude is allocated to binary 0, and a second frequency having a magnitude greater than or smaller than a predetermined reference value than the first frequency is allocated to binary 1. In addition, format information of the transmission item of FIG. 2 may be stored.

The wired/wireless communication unit 240 transmits/receives data to and from one or more black boxes 100 through a network (not shown). Battery state information may be received from one or more black boxes 100 .

The control unit 250 controls the operation of each component of the monitoring device 200 .

The display unit 260 displays the information analyzed by the physical signal analysis unit 220 on the screen.

Based on what has been described so far, the physical signal transmission process of the black box will be described as follows.

9 is a flowchart illustrating a physical signal transmission method according to an embodiment of the present invention.

Referring to FIG. 9 , the plurality of sensors 110 collects each sensed value ( S101 ) and outputs it to the processor 140 .

The control unit 145 of the processor 140 determines whether an impact occurs based on the sensed value (S103), determines whether an inclination occurs (S105), and determines whether a high temperature occurs (107). At this time, if none of the steps S103, S105, and S107 apply, the battery state information is transmitted to the monitoring device 200 through the wired/wireless communication unit 170 (S109).

On the other hand, if at least one of the steps S103, S105, and S107 is applicable, it is determined whether a physical signal is detected from the other black box 100 (S111).

At this time, if another physical signal is detected, a random time waits (S113). Then, step S111 is performed again.

When another physical signal is no longer detected, the physical signal generating unit 143 generates and transmits the object identification information, the sensing item, and the sensing value as a physical signal (S115 and S117).

10 is a flowchart illustrating a physical signal generation process according to an embodiment of the present invention.

Referring to FIG. 10 , the processor 140 generates mapping information in which different frequencies or different wavelengths are allocated to binary numbers (0, 1), respectively, and stores the generated mapping information in the storage unit 130 (S201).

Thereafter, the conversion unit 141 converts the object identification information and the sensed value into binary numbers (S203). Then, the physical signal generating unit 143 generates the object identification information, the sensing item, and the sensing value converted into binary numbers as physical signals having different frequencies or different wavelengths in succession ( S205 ).

The embodiment of the present invention described above is not implemented only through the apparatus and method, and may be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium in which the program is recorded.
