The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will be defined by the claims . Like reference numerals refer to like elements throughout the specification.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an apparatus and method for displaying a location of a victim according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The embodiments of the present invention are described in sufficient detail to enable the present invention to be realized by those skilled in the art, and other embodiments can be used, and various modifications within the scope of the present invention Lt; / RTI >

1 is a block diagram of a wireless local area telecommunications distress location display apparatus according to an embodiment of the present invention.

The wireless local area distress location display apparatus 100 according to the present embodiment detects a distress situation when the tilt value and the tilt value are maintained for longer than a reference time in a distress situation, You can check the status.

In addition, the rescuer transmits and receives mutual distress signals and tracks the relative distress signals to the wireless local-distress location display device 100 (hereinafter referred to as "device") worn by the victim. In order to find the precise location of the victim, wireless distant communication is used to send and receive mutual distress signals, and visual and auditory signals are generated step by step according to the degree of mutual distance, so that the position of the victim is displayed .

To this end, a configuration for performing wireless local area communication between users wearing the device 100 using the user's tilt information and location information of the device 100 is provided. Refer to Fig. 1 for its construction.

To this end, a tilt information section 10 for detecting a tilt value is constructed.

The tilt information unit 10 may include a gyro sensor, an acceleration sensor, a tilt sensor, or the like, which detects the tilt value.

A timer 20 for measuring time is constituted.

The timer 20 is configured to detect the time at which the tilt value is maintained, and is used as an auxiliary means to determine the distress state.

And a communication unit 30 for transmitting and receiving the distress signal through the wireless local area communication.

The communication unit 30 includes a transmitter for transmitting the distress signal to the surrounding area and a receiver for receiving the distress signal transmitted from the external device 100.

The control unit 40 is configured to determine the distress state and transmit / receive the distress signal to relatively measure the position between the transmitting / receiving devices 100.

When the slope value reaches the distress setting slope and continues for more than the set time of distress, it is determined that the distress is present. The distress setting slope and the distress setting time can be arbitrarily set as a reference value for determining a distress condition.

For example, when the distress setting slope is 45 degrees or more and the distress setting time is set to 1 minute or more, when a firefighter with the device 100 falls into a distress situation due to an unexpected accident while performing the mission, Since the slope information section 10 of the apparatus 100 continuously detects the slope value, if the slope value exceeds 45 degrees due to the fall of the fire brigade, and the situation continues for more than one minute, 100 determines that the distress situation is a distress situation. Then, the distress signal is transmitted to the peripheral device 100 through the communication unit 30, and the distance to the received device 100 is extracted by signal exchange to the wireless local area communication. The extracted position is used to control the display portions 50a and 50b and the alarm portion 60 described later.

And a display unit 50a (b) for visually displaying the distress state according to the distress signal.

The display portions 50a and 50b include a visual display of the unique identification mark of the device 100 when the visual signal is output in a distress situation and normally.

The display portions 50a, b may be attached to at least one user. When one of the display units 50a and 50b is used, the visual signal outputted at the time of the distress and the unique identification mark of the device 100 are displayed in one form.

The time signal is a signal output at a constant time interval. As the distance between the receiving device 100 and the transmitting device 100 decreases, the time interval of the output signal of the distress signal decreases stepwise It works. The unique identification mark of the device 100 and the time signal may be output in the same form.

The time signal is such that the time signal is the color, shape, and the font of the light output at the time of distress, and can be recognized through time.

For example, the name displayed at the time of distress flickers when a unique identification mark is being displayed under the wearer's name. Alternatively, the name may be changed to a character such as 'distress' or 'HELP' to perform a flicker operation.

And an alarm unit 60 for audibly providing the distress state according to the distress signal.

The alarm unit 60 can adjust the output speed of the output audible signal. The audible signal is a signal output at a predetermined time interval. As the distance between the receiving device 100 and the transmitting device 100 decreases, the volume of the distress signal increases stepwise, And the time interval of the output signal of the signal processing unit is stepwise shortened.

The alarm unit 60 generates the audible signal and is a device for allowing the surrounding users of the device 100 to listen to the sound when the user is distressed.

FIGS. 2A and 2B are state diagrams of a wireless local area distress location display device according to an embodiment of the present invention mounted on a helmet for fire fighting purposes.

A fire helmet 200 wireless local area distress location display device 100 is attached and is shown in FIG. 2A. A display unit 50a and a display unit 50b are attached to the front and rear sides of the display unit 50 and a power supply unit, a tilt information unit 10, a timer 20 control unit 40, an alarm unit 60, A housing 210 is attached.

The display screen of the front side display 50a and the rear side display 50b may be different.

The housing 210 is connected to the front and rear displays 50a and 50b using power (power supply), tilt information section 10, timer 20 control section 40, alarm section 60 and communication section 30 And transmits an identification number and a distress signal of the wearer who is in danger at the time of an emergency to the peripheral device 100.

For example, the unique identification code of the victim and the RSSI (Received Field Strength) value may be displayed at 50a, and the unique identification code of the wearer may be displayed at 50b.

The front display 410 is configured so as not to obstruct the view of the firefighter as much as possible. This is illustrated in FIG.

In Fig. 2 (b), it is located below the left side of the helmet but not at the designated position.

3 is a flowchart illustrating a method of displaying a location of a WLAN destructor according to an embodiment of the present invention.

 3, a unique identification code is displayed on the display 50a, b (S201). The unique identification code is one for each user who attaches the device 100, and may be a name, an alias, an affiliation, a number, and the like.

Next, the tilt value of the device 100 is sensed (S202). The slope value is continuously collected, and is a value that is detected by the slope information section 10.

Next, if the disturbance setting slope value that can be determined to be the distress state is determined, it is determined whether the disturbance setting value is longer than the disturbance setting time (S203) to determine the distress state. If the distress setting time is equal to or longer than the distress setting time, it is determined that the user who installed the device 100 is distressed (S204).

Next, when the distress state is determined, the distress signal is transmitted through the communication unit 60 (S205). It also tracks the location between the devices 100 in the intercommunication exchange with the device 100 receiving the distress signal in the vicinity.

Next, the position of the distressed device 100 is provided to the peripheral area through the display units 50a, 50b and the alarm unit 60 using the visual and audible signals (S206a, b). At this time, the time signal may also flicker at certain time intervals. The audible signal may be a Morse code indicating a distress or may be a sound output at a predetermined time interval. For example, if the predetermined time is 2 seconds, the display units 50a and 50b and the alarm unit 60 output the time and auditory signals at intervals of 2 seconds.

Next, the distance between the distressed device 100 and the device 100 receiving the distress signal is checked (S207). When the distances are closer to each other, the distance between the distressed device 100 and the distressed device 100 The signal changes stepwise. At this time, the above-described change may occur in the case where the flickering speed of the time signal generated by the display units 50a and 50b is gradually increased, and in the case of the audible signal generated by the alarm unit 60, have.
