Description

Drones for kids and pets

The present invention relates to a drone, and more particularly, to induce interest and interest in infants or companion animals to induce natural movement indoors, and furthermore, to put snacks or food in toys so that infants or companion animals are floating in the air. It relates to a drone for infants and pets that can jump and touch a toy so that snacks or food are naturally discharged when it is touched, and furthermore, it can remotely feed pets when they need to be fed.

In general, a drone refers to an unmanned airplane that flies through remote control on the ground without a human being on the aircraft. Drones are being developed in a way to obtain sufficient lift by using a plurality of propellers mounted on the fuselage. This method is similar to the existing helicopter maneuvering method. Alternatively, when a plurality of propellers are attached to the fuselage, a method of determining the propulsion direction of the fuselage by differentiating the thrust of each propeller is used. With respect to such a helicopter type drone, Korean Publication No. 10-2014-0038495 discloses a drone using four propellers radially disposed from the center of the fuselage.

Republic of Korea Patent No. 10-1650136 discloses a technology for controlling a drone through an application module for drone control activated in the form of an application on the screen of a smart device (eg, smart phone, smart TV, digital signage) without a separate main control board. is starting However, according to Republic of Korea Patent Registration No. 10-1650136, while controlling the overall operation of each device, the state of each sensor, the surrounding environment data, and the value of the current drone attitude are calculated and combined to process landing, take-off, fly, and stationary flight. To autonomously control drone attitude control, flight navigation, and wireless communication, a GPS sensor is included as an essential component.

Accordingly, there is a problem in that the production cost of a drone equipped with a GPS sensor is high and productivity is lowered. In addition, when the altitude is controlled using the GPS sensor, the GPS sensor may malfunction or it may not be possible to accurately control the altitude in the GPS shadow area. This causes problems in which expensive drones collide with buildings and are damaged or lost because they deviate from the expected route.

In order to solve this problem, the inventor of the present applicant disclosed in Korean Patent Registration No. 10-1958264, a drone capable of stably performing a mission at a specific altitude by being able to maintain an altitude even without using an expensive GPS sensor.

Meanwhile, as the number of single-person families and families raising companion animals increases these days, interest in companion animals and devices that can manage and care for companion animals more easily and conveniently are required. However, drones for companion animals have not yet been developed because the production cost of drones is high and can be damaged quickly when a companion animal touches it.

As shown in FIG. 5, the electronic device of a drone for infants and companion animals is basically a communication unit 511, an actuator 512, a sensor unit 514, a power supply unit 515, and a control unit 516. implemented including. In addition, an optical/sound output unit 513 may be provided.

The communication unit 511 can be considered only a transceiver for manipulation, but various communication methods are used due to an increase in external sensors and an increase in operation modes. The transceiver is a communication device that transmits the control signal of the remote control unit 520 to the control unit 516, and a PPM type 2.4Ghz transceiver is mainly used.

The actuator 512 includes a plurality of motors and a plurality of propellers and an electronic speed controller (ESC) interlocked with the plurality of motors and installed at different positions. The motor has relatively large power (torque), and it is preferable to use an efficient and light brushless motor.

The sensor unit 514 includes an acceleration sensor for detecting the flight speed of the drone, a gyro sensor for detecting the inclination of the drone, and an altitude sensor for detecting the altitude of the drone. The altitude sensor may be implemented as a barometric altimeter or a radio altimeter. The barometric altimeter measures the altitude at the current location using the barometric pressure difference between the reference barometric pressure (sea level barometric pressure) data and the currently measured barometric pressure. Since barometric altimeters are highly temperature dependent, they include a temperature sensor. The barometric altimeter can be implemented as an aneroid barometer using the principle that the upper surface of a metal box in a vacuum contracts and expands according to changes in atmospheric pressure. The radio altimeter is placed under the drone and measures the altitude using ultrasonic waves. The sensor unit 514 may be implemented to further include a GPS sensor. Serial communication or I2C communication is mainly used for communication between the sensor unit 514 and the control unit 516 .

The power supply unit 515 includes a rechargeable battery. The battery is very light, can be transformed into almost any size and shape, and can be implemented as a LIPO battery that can store a large capacity for its size. Battery current is supplied to the motor through the electronic transmission (ESC), and the electronic transmission (ESC) rectifies the supplied power to the controller operating voltage in UBEC, a kind of voltage regulator, so that a part of the supplied power can be used by the flight controller or sensor (usually rectified to 5V).

For a small drone that provides only a simple flight mode, it is sufficient to supply power to the flight controller through this UBEC, but when the drone uses various voltage-sensitive sensors, excessive current use of the motor may result in the UBEC attached to the electronic transmission (ESC). A separate power module may be used because it may affect the rectification stability of the device.

The electronic transmission (ESC) serves to rotate a motor according to a control signal generated by the control unit 516 based on data from the sensor unit 514 to generate propulsion force through the propeller. The control unit 516 is not designed to transmit enough power for the motor to generate sufficient driving force, but only sends a signal (PWM type) to generate a certain amount of power to the electronic transmission (ESC). The electronic transmission (ESC) provides power required for a sufficient rotation speed of the motor according to a signal transmitted from the control unit 516 .

The control unit 516 is, for example, an APM board (8bit 16Mhz) based on the Arduino Mega of the open source Multiwi platform, ST Micro's ARM Cortex M3 CPU operating at 32bit 72Mhz, and Qualcomm's 64bit Quad-core operating at 2.26GHz. It can be implemented with a Snapdragon SOC (System on Chip) based board.

The controller 516 generates altitude data using a sensor value input from the altitude sensor, generates posture data using sensor values input from the acceleration sensor and the gyro sensor, and inputs the altitude data and posture data and input through the communication unit. Each of the plurality of motors is controlled using the remote control signal.

According to an embodiment, the control unit 516 includes an event detection unit 5161, a virtual coordinate generation unit 5162, an altitude maintenance control unit 5163, and a toy control unit 5164, as shown in FIG. do.

The event detection unit 5161 may be implemented to detect whether an altitude maintenance command is input from the remote control device through the communication unit 511 . The event detection unit 5161 may be implemented to detect whether an automatic mode operation command is input from the remote control device through the communication unit 511 .

The virtual coordinate generating unit 5162 sets an arbitrary reference point in the space in which the drone is flying as virtual coordinates. In order to set the virtual coordinates, based on the altitude data measured by the altitude sensor, input from the acceleration sensor and the gyro sensor Posture data generated from sensor values is used. For example, the virtual coordinate, which is an arbitrary reference point in space, may be (0, 0, altitude value, θｘ, θy, θz) at the event occurrence time t1. Here, θｘ, θy, and θz are the x-axis, y-axis, and z-axis inclination angles, respectively.

The altitude maintenance control unit 5163 controls the actuator 512 using the virtual coordinates generated by the virtual coordinate generating unit 5162, the second altitude data, and the second posture data. For example, the altitude maintenance control unit 5163 moves up and down, left and right using the altitude data measured by the altitude sensor and the posture data generated from the sensor values input from the acceleration sensor and the gyro sensor even if the drone deviates from the virtual coordinates due to disturbance. , and controls the actuator 512 to move the drone to virtual coordinates.

The altitude maintenance controller 5163 may control the actuator 512 to make an emergency landing of the drone while maintaining a safe altitude. For example, when the altitude value change information is input from the remote control device 520 through the communication unit 511, the virtual coordinate generator 5162 changes the altitude value corresponding to the z value from the preset virtual coordinates to a new virtual coordinate. can create The altitude maintenance control unit 5163 controls the actuator 512 using the new virtual coordinates generated by the virtual coordinate generating unit 5162, the second altitude data, and the second posture data. As a result, the drone can safely make an emergency landing.

The toy control unit 5164 generates a control signal for controlling when the light/audio output unit is provided in the companion animal toy 160 , and connects the toy 160 for infants and companion animals through the toy connection member 150 . It communicates and transmits control signals.

The light/sound output unit 513 is configured with an LED light source, a speaker, or a beep sound generator, and outputs an optical signal or a sound signal generated by the toy control unit 5164 to induce interest in companion animals. The light/sound output unit 513 may be provided in the toy 160 for infants and companion animals. In this case, the electrical signal of the toy control unit 5164 is transmitted through the toy connecting member 150 to toys for infants and companion animals. It is transmitted to the light/sound output unit (not shown) provided in 160 . The toy 160 for infants and companion animals may receive power from the drone through the toy connection member 150 formed of an electric wire.

On the other hand, companion animals such as cats and dogs have much better hearing than humans. Humans can hear a range of 20 to 20,000 hertz, cats can hear a range of 60 to 65,000 hertz, and dogs can hear a range of 15 to 50,000 hertz. Accordingly, a caution signal, a food alarm signal, and the like can be generated and provided to companion animals using frequencies in a sound range that are inaudible to humans but are audible to dogs and cats. Therefore, the present invention can be implemented to remotely control a drone using a smartphone using Bluetooth, Wi-Fi communication, etc. even outdoors to remotely feed the companion animal at a time when it should be fed.

6 and 7 are exemplary views of a snack or food supply device for a drone for infants and companion animals according to the present invention.

6 and 7 , the companion animal toy 160 is used as a snack or food supply device.

In FIG. 6 , the food container 170 has a cylindrical shape with an opening formed at one end, such as a conch shell, and stores snacks for infants or food for dogs or cats. It may be implemented such that the snack container or the food container 170 is tilted by the shock or the external force as the drone moves, and the built-in snack or food 172 is discharged to the outside through the opening. In addition to this, the snack or food providing device may be implemented in a manner in which an opening and closing door is added to the opening so that a certain amount of snacks or food is discharged to the outside at a time.

In the case of FIG. 7 , the body 180 of the toy 160 for infants and companion animals consists of food itself. The wing portion of the toy 160 for infants and companion animals and the body 180 are connected by a detachable ring (dotted line portion) so that the infant can eat snacks or the companion animal can eat food.
