Description

Lifesaving Drones {Drone for rescuing people}

The present invention relates to a drone that helps rescue people in rescue situations in situations where rescue personnel are hard to input using drones.

Drones, named after unmanned aerial vehicles (UAVs) or buzzing buzzing sounds, are remote piloted, preprogrammed routes from the ground, without pilots boarding directly on the aircraft. Aircraft and ground control equipment (GCS) that perform missions according to their own environmental judgment by autonomous flight or artificial intelligence in auto-piloted or semi-auto-piloted format, and Data link General name of the whole system such as Support Equipments. RC airplanes will require a flight controller to control the plane, but drones may not require a controller.

Operate in conjunction with independent systems or with space / ground systems. It is equipped with various equipments (optical, infrared, radar sensors, etc.) according to the field of use, and performs the tasks of surveillance, reconnaissance, guidance of precision attack weapons, communication / information relay, EA / EP, Decoy, etc. The weapon itself has been developed and put into practical use, attracting attention as a major means of military power in the future. In recent years, rapid growth has been taking place. In June 2017, Amazon filed a patent for a drone take-off and landing center.

Drones can float in the air by the propeller's rotation and can fly by the induction of radio waves. Drones are remotely controlled from a distance, so they are designed for ease of control. For example, the drone may be provided with a plurality of propellers and a plurality of motors.

Meanwhile, due to the development of wireless technology, a drone, a small wireless reconnaissance flying object possessed by an individual rather than a military, has been commercially available. Drones can be manipulated to fly cameras for firefighting or access to disaster areas, to capture terrain information, for broadcast or military purposes.

Usually, drones are operated by radio controls based on GNSS position information, and most drones are very easy to adjust their position and direction by using multiple helicopters and horizontal rotorcraft.

In particular, it is possible to shoot in the stationary state, so it is used for taking selfies or video for broadcasting.However, selfie shooting requires the user to operate the drone by hand, and video shooting is performed by a separate drone controller. .

Therefore, it can be used in places such as fire scenes, deep mountains or wooded forests where people cannot access directly, and use the thermal imaging camera or microphone to recognize the sound of a person even in extreme conditions where visibility is low. It can be used as a drone to support rescuers.

With reference to Figures 3 to 4 will be described how to find a person to rescue by applying the lifesaving drone according to the present invention.

Referring to FIG. 3, after a person flies to a place where it is difficult to directly enter, a sound signal input from the outside is received through the microphone 500. Thereafter, the microphone 500 modulates and amplifies the modulation signal through a modulation amplifier 510 for modulating and amplifying the input sound signal. Next, the voice signal processor 530 compares and analyzes whether the sound signal input from the modulation amplifier 510 includes the same voice signal as the voice model stored in the voice model storage unit 520. When it is determined that the determination result of 530 is the same voice signal, an alarm signal is generated through the input / output port 540 through the speaker 600. Thereafter, the wireless communication unit 300 transmits a rescue request signal to nearby rescue workers and control rooms.

In this case, the speaker 600 may broadcast the desired signal by controlling the speaker 600 remotely through the terminal 310 as well as the alarm room or the user.

To describe the configuration of the microphone 500 in more detail, a microphone 500 that receives a sound signal from the outside, a modulation amplifier for modulating and amplifying the sound signal input from the microphone 500, a microphone The 500 may use a microphone which is generally used, and its performance may vary depending on the location. In addition, the modulation amplifier 510 may also use a modulation circuit and an amplification circuit, which are generally known, and preferably consist of one chip.

On the other hand, it represents a voice model storage unit (520, FLASH ROM) for storing a program and a voice model necessary for the operation of the system, and is driven in accordance with the program stored in the voice model storage unit 520 from the modulation amplifier 510 The signal processor determines whether the input sound signal includes the same voice signal as the voice model stored in the voice model storage unit 520. At this time, the voice model stored in the voice model storage unit 520 is a sound having a size greater than the reference value, "please help", "please help", "to save people," "evil", "Ah", "cheap", Words that can come from emergencies such as "burglary," "thief," "help me," and "freeze," preferably with a whistle. At this time, when determining the voice model is collected under a variety of people and environments to build a database (DB).

In addition, the voice signal processing unit 530 removes noises such as car sounds, ordinary human sounds, office noise, indoor living environment noise, and natural sounds from sound signals input through the modulation amplifier 510. It is preferable to have. The sound of the car includes a crashing sound, a brake holding sound, a horn sound, and the like, and the natural sound includes a rain sound, a wind sound, a cat sound, and the like.

The voice signal processor 530 may have an input / output port 540 for outputting a control signal to a module (not shown) that generates an alarm signal when the same voice signal is included. When the determination result of the signal processing unit 530 includes the same voice signal may further include a serial input and output device for transmitting a rescue request signal to the central control center (not shown).

In addition, the voice signal processor 530 may perform a function of generating a clock and may further include an oscillator that performs a function as a buffer with a plurality of SRAMs.

Next, referring to Figure 4, after the flight to a person difficult to enter directly, take a continuous shooting with the camera 400. At the same time, the laser emitter 410 emits a planar laser to the front, and the laser receiver 420 receives the laser. Subsequently, the laser distance received by the shape generation operation unit 400 is calculated and generated as a shape based on the calculated result, and the shape signal processing unit 450 generates the shape and shape model storage unit generated by the shape generation operation unit 440. In step (430), the shapes stored in advance are compared to analyze whether the same shapes are included. Subsequently, when it is determined that the shape model of the shape signal processing unit 450 matches the shape model, an alarm signal is generated through the input / output port 540 through the speaker 600. Thereafter, the wireless communication unit 300 transmits a rescue request signal to nearby rescue workers and control rooms.

In addition, in the case of the camera 400, a thermal image camera may be used to detect a signal of a rescued person. The thermal imaging camera is installed outside the body 100 and detects heat of a structure target. Thermal imaging cameras can be used for two purposes. The thermal imaging camera measures and records the thermal radiation of an object electronically. An image of different colors according to the measured temperature is output on the screen. Therefore, even if a field of view is not secured due to smoke or darkness at a fire site or a rescue site, it is possible to detect whether there is a rescued person by detecting heat emitted from a human body.
