A diagram schematically shown, and FIG. 4 is a view showing an operation method of the drone radio controller of FIG. 1 .

1, a drone manipulator binding system (hereinafter, drone manipulator binding system) 90 for a virtual drone training simulator according to an embodiment of the present invention includes a drone manipulator 100, a hub device 110, and a simulator. Some or all of the device 120 .

Here, “including some or all” means that some components such as the hub device 110 are omitted so that the drone manipulator 100 and the simulator device 120 perform direct communication (eg, P2P communication), or the hub It means that some components such as the device 110 can be configured by being integrated with other components such as the simulator device 120 , and it will be described as including all components to help a sufficient understanding of the invention.

The drone manipulator (or drone radio controller) 100 of FIG. 1 according to an embodiment of the present invention includes a manipulator operation unit 101 and a signal transmitter 103, and for example, a manipulator capable of operating a real drone as shown in FIG. use the same model as For example, if a user actually purchases a drone before flying training outdoors, or if a specific drone is used at an educational site, the actual drone may be used to prepare for this.

The drone manipulator 100 is generally provided with two control sticks, and the operation method of the manipulator has two operation methods. This may be referred to as mode 1 or mode 2. This is the control method designated as the standard in the global RC industry. Mode 1 is mainly an airplane-derived control method, and the devices located at the rear of the airplane, i.e., the rudder and elevator, are controlled with the left hand, and the engine output (throttle) and rolling (aileron) are controlled with the right hand. This is a great way to fly an airplane and has a long history, but even in the world of right-handed people, there are a few things the left hand is better at, and one of them is steering. As such, mode 1 can be seen as a method of controlling direction-related things with the left hand. On the other hand, mode 2 uses the right hand to adjust the cyclic pitch of the rotor, and since most helicopter crashes are often caused by failure to adjust the cyclic pitch, adjusting both with one hand may be more responsive. can And in general, helicopter users are more likely to prefer mode 2.

In either mode 1 or mode 2, the collective pitch is used in conjunction with the throttle stick, and the collective pitch is set to increase as the throttle increases. Depending on the person, it is possible to specify the two differently, such as setting the throttle to increase rapidly at the beginning, gradually increase when it exceeds 50%, and increase the collective pitch linearly.

Of the 4 sticks, except for the throttle, the rest of the sticks have a spring inside, so that they always maintain the center position if left untouched, and the stick stays in place even if the throttle stick is released. Most remote controllers allow the user to programmatically set Mode 1 and Mode 2, but nevertheless, it may be necessary to disassemble the remote controller once when changing modes due to the problem of the spring returning the stick to its original position. Therefore, it is convenient to buy a remote controller set to the desired mode if possible.

Flight operations using the drone controller 100, for example, throttle, roll (or rolling), yaw (or yaw), pitch (or pitching), etc. are already well known in relation to, so detailed description will be omitted.

As described above, the drone manipulator 100 according to an embodiment of the present invention registers the drone manipulator 100 possessed in order to control the virtual drone in the simulator device 120, and registers the drone manipulator 100. In the following process, a pairing operation of registering each other's identification information may be performed, and in this process, a mode of the drone controller 100 and an attribute value of a corresponding product or model may be set. Through this process, you can have the same feeling as flying a drone in a real environment.

The hub device 110 is a wireless repeater that receives the manipulator signal and converts the received signal. The hub device 110 may be a product as shown in FIG. 4 . The hub device 110 includes a signal receiver 111 that receives a signal transmitted from the drone controller 100, a signal converter 112 that converts the received signal into a signal that can be accepted by a computer, for example, and the converted signal. It may include a USB hub 114 that the computer accepts, and the like. The hub device 110 receives a control signal through wireless communication with the drone controller 100 , and for this, the hub device 110 may receive a control signal from the drone controller 100 in a band of 2.4 GHz. The hub device 110 may convert the control signal of the drone manipulator 100 and transmit it to the simulator device 120 through a cable. The control value of each analog stick in the drone controller 100 has a value of 0 to 255, changes the value of 0 to 255 of each channel to PWM, and converts the values of several channels into PPM to convert the values of several channels into a receiver that is a simulator device. The PPM transmitted to 120 and received by the simulator device 120 is again converted into PWM of each channel, and the PWM can be sent to the transmission from a processor, for example, a CPU or an MPU. In this process, the hub device 110 may encrypt the converted PPM signal and transmit it to the simulator device 120 . Encryption may be performed in the encryption unit 113 .

The simulator device 120 includes various devices such as a desktop computer, a laptop computer, a tablet PC, and a smart TV. The simulator device 120 recognizes when the hub device 110 is connected, and when the drone manipulator 100 requests access, it can register identification information with each other and perform a pairing operation for communication. The simulator device 120 is a calculation system 123a that converts a signal input from the hub device 110 according to the environment of the simulator 123, that is, a calculation unit, and converts the calculated output values to the roll and pitch of the virtual drone. ), Yaw, and a binding system that connects to the throttle, that is, the binding unit 123b, and a software system that ultimately determines the motion of the virtual drone through the binding system, that is, the virtual drone unit 123c. may include. Here, binding refers to controlling, ie, connecting, the virtual drone.

The simulator device 120 includes a kind of engine, that is, the simulator 123 for performing the operation according to the embodiment of the present invention. Of course, the engine may be configured by software (S/W), hardware (H/W), and a combination thereof, but S/W is preferable in the embodiment of the present invention. In the simulator device 120 , the wind, humidity, and area of the environment that are affected when the virtual drone moves are set. In addition, in the virtual drone, the weight, material, output amount of the motor, etc. are set for each part, and the signal received from the real drone radio controller is converted and calculated by referring to the environmental variables in the simulator 123 made with the engine. . The calculated signal is applied to the movement of the virtual drone.

For example, in the embodiment of the present invention, signal transmission/reception between the wireless drone controller 100 and the PC and the signal of the drone controller 100 received from the PC are sent to the virtual drone by referring to various environment setting variables of the simulator. do. The operation signal of the drone controller 100 is wirelessly transmitted and received, the signal is converted according to the virtual environment, the output amount is calculated, and the signal is transmitted to the virtual drone. More specifically, the environment variables (pre) set in the control value calculation system 123a of the virtual drone training simulator 123 are set in mode 1 or mode 2 as in FIG. 3, air volume (or wind pressure), and whether automatic hovering is performed. In addition to , humidity, parameters such as control sensitivity and temperature may be added or deleted as needed. Here, hovering refers to a state in which the drone stays there without moving after it is in the air, and the automatic hovering refers to a function that allows the drone to remain in the air automatically even when the user releases his or her hand from the remote controller. In addition, the wind volume is the amount of wind and is expressed in volume per unit time, and the wind pressure is the pressure of the wind, that is, the pressure applied to the unit area of the object when the wind hits an object, and is expressed in mmAq.

In this way, when the drone manipulator 100 is used, the simulator device 120 may register it, that is, perform a process for a pairing operation. Of course, the simulator device 120 may receive not only identification information such as a device ID, but also an attribute value related to a product attribute while performing a pairing operation of the corresponding drone controller 100 . The virtual drone has a 3D graphic model and a member variable such as parts, weight, material, and durability of the drone. The virtual drone includes a quadcopter, a hexacopter, an octacopter, etc. according to the number of wings, and each configuration and property is set (or stored) in the control value calculation system 123a. In this way, in the case of pre-stored attribute values related to products sold in the market, by using model name information such as model name, device information, etc., the corresponding attribute value is selected and preset, and then the control signal of the drone controller 100 is received. The virtual drone can be controlled by converting the attribute value into a reflected value.

Of course, the simulator device 120 may further apply a flight environment set by a user or automatically set to control the virtual drone. For example, when a user sets up a flight environment and wants to train a flight by selecting a specific flight environment, the virtual drone can be controlled by generating a result value in consideration of the environment.

The simulator device 120 may operate in various ways to set attribute values of the drone manipulator 100 and environmental data of a place where flight training is performed. For example, related data is preset and selected at the initial stage of installation of the simulator 123 . In addition, when there is no preset data, an operation of setting the data may be performed by accessing an external server or the like through the Internet. For example, if there is no registered product, the relevant information may be collected and used by accessing the manufacturer's server or by accessing an external device that sells the product. In addition, when a user wants to perform flight training in a specific place (eg, eup, myeon, dong, etc. in an administrative district) and requests related weather information to the Meteorological Administration server or an external device, the user receives weather information temporarily or in real time You can use it to fly a virtual drone.

For example, a 3D graphic model preset on the screen of the monitor may be displayed on the screen. The monitor can display two control sticks that can move freely up, down, left, and right, and information about the remote controller and the interacting drone if necessary. The simulator device 120 does not display the previously produced and stored 3D graphic model on the screen as described above, but when the user sets a specific location, it collects map information of the corresponding place, and the current weather condition and By collecting related weather information and implementing graphics together with a virtual drone on the screen, the user can perform the same training as the real environment that he or she wants through the real drone controller that he or she has purchased or currently has through the simulator device 120 . it will be possible

The simulator device 120 according to the embodiment of the present invention includes a control value calculation system 123a, a binding unit 123b, and a virtual drone unit 123c as a simulator 123, and in addition to data from the hub device 110 It may further include a data receiving unit 121 for receiving. The data receiver 121 may decrypt encrypted data. The virtual drone unit 123c may perform an operation for synthesizing the background graphic and the virtual drone and displaying the synthesized image on the screen. The binding unit 123b may perform an operation of connecting an output value output from the steering value calculation system 123a to control a specific movement of the virtual drone. For example, if the drone is accelerating when moving forward, the accelerator may be operated based on the acceleration information. It can be seen that the binding unit 123b performs an operation of connecting to a roll, a pitch, a yaw, and a throttle of the virtual drone.

FIG. 5 is a block diagram illustrating another detailed structure of the simulator device of FIG. 1 .

As shown in FIG. 5 , the simulator device 120 ′ of FIG. 1 according to another embodiment of the present invention includes a communication interface unit 500 , a control unit 510 , a virtual drone simulator unit 520 , and a storage unit 530 . ) in part or in whole.

Here, “including some or all” means that some components such as the storage unit 530 are omitted, or some components such as the virtual drone simulator unit 520 are other components such as the control unit 510 . It means that it can be integrated into and configured, and it will be described as including all in order to help a sufficient understanding of the invention.

The communication interface unit 500 performs communication with, for example, the drone controller 100 or the hub device 110 of FIG. 1 . For example, the operation of the hub device 110 of FIG. 1 may be executed after being set in the simulator device 120 ′ of FIG. 5 by software. The communication interface unit 500 may perform an operation for setting the drone controller 100 (eg, a pairing operation) according to a user's request at the beginning of the operation, and when the registration procedure is completed, a flight for flying the virtual drone You can receive information related to the place. Of course, the user will be able to set one of a plurality of pre-made and stored flight locations.

Prior to this, the communication interface unit 500 may set various information by performing communication with the drone controller 100 . For example, an attribute value related to a product model of the drone manipulator 100 may be set. For example, it is possible to receive identification information such as a device ID through a pairing operation and at the same time receive model name information related to a model name. Accordingly, based on the model name information, the user may be asked whether the attribute value for a specific model is correct, and an operation of setting may be performed after receiving confirmation through this.

Of course, if the attribute value for a specific model is not stored in advance, it may be connected to the manufacturer's server to receive the attribute value related to the model. Through this, it may be possible to add attribute values pre-stored in the internal memory.

When the setting operation as described above is completed, a virtual drone may be displayed on the screen of the simulator device 120 according to a user's request, and the user may control the virtual drone by manipulating the drone controller 100 possessed. When operating the virtual drone in this way, the virtual drone can fly by reflecting the attribute value of the preset model and the setting value for the flight environment. For example, even if the air volume is the same, the movement of the virtual drone may appear differently depending on the weight or material of the model. In this way, when there is manipulation of the virtual drone by the user based on the attribute value or the flight environment, it can be displayed on the screen as if flying the drone in the real (real) environment.

The control unit 510 is responsible for overall control operations of the communication interface unit 500 , the virtual drone simulator unit 520 , and the storage unit 530 of the simulator device 120 ′ constituting FIG. 5 . When there is a request for a pairing operation through the drone controller 100, the controller 510 executes the virtual drone simulator 520 to register the drone controller 100 or the hub device 110. Can be performed. have. For example, in the embodiment of the present invention, a registration operation may be performed through the hub device 110 of FIG. 1 , but the use of the hub device 110 in this way is to actually sell the drone manipulator 100 in the market. It can be seen that this is to enable virtual simulation to be performed through the product being developed.

In other words, in the case of a real drone, the actual radio frequency may communicate in a band of 2.4 GHz. Therefore, in consideration of this point, it can be seen that the hub device 110 is used to maintain compatibility of the simulator device 120 ′ with an actual product sold on the market. For example, if only simulation is performed, the corresponding operation does not use a separate hub device 110, and it is possible to use short-range wireless communication such as Wi-Fi, Zigbee, or Bluetooth. have. Of course, the drone controller 100 or the simulator device 120' automatically recognizes this in parallel, that is, when the user selects one of the two methods, or when the hub device 110 is not connected. Although the pairing operation and the control operation may be performed through the wireless communication module, a method using the hub device 110 may be preferable in consideration of cost. However, the embodiment of the present invention will not be particularly limited to any one method.

Also, the controller 510 may control the virtual drone simulator 520 to set various information related to the flight environment according to a control signal provided from the drone manipulator 100 . As mentioned above, it is possible to set the attribute value of the drone controller 100 and data related to the flight environment of the place where the virtual drone is flying. For example, in the same flight environment, that is, when there is a wind direction or speed, when flying a light drone and flying a relatively heavy drone, the resistance to wind is inevitably different. It is possible to control the virtual drone simulator unit 520 to generate these attribute values and result values related to the flight environment.

The virtual drone simulator unit 520 performs a pairing operation for communication so that the virtual drone displayed on the screen can be controlled by the drone controller 100, that is, an operation of registering identification information such as device IDs of each other. In addition, an operation may be performed to select an attribute value of the drone, a place for flying a virtual drone, or set flight environment information. For example, when a user selects a specific place for flying a virtual drone, environmental data related to a flight environment may be preset in the selected specific place. Therefore, when the environment data is set, the virtual drone simulator 520 receives an operation signal, ie, a control signal, of the drone controller 100 when the user selects a specific place and requests flight training, and responds to the received control signal. Based on the attribute value of and the flight environment data of the place where the flight training takes place, the result value to be applied to the virtual drone is calculated. The motion of the virtual drone is controlled with the calculated result value. For example, when shaking of the virtual drone needs to occur, the virtual drone simulator unit 520 generates the shaking in the pre-made 3D graphic so that the image is implemented on the screen.

Of course, in this process, related information may be provided to the drone controller 100 in order to reflect such shaking in the drone controller 100 . Through this, it is possible to increase the feeling of a user flying a real drone through the drone controller 100 .

In addition, the virtual drone simulator unit 520 when the user directly designates a place where the user wants to fly the virtual drone through the drone controller 100, for example, when he or she designates a specific place such as an education training center through a search box, The graphic displayed on the screen may be generated by collecting map information of the corresponding education and training ground. In this process, the weather information of a specific place is also connected to the external device of the Korea Meteorological Administration and is received in real time or periodically and applied as the above environment data so that the virtual drone can fly according to the operation of the user's drone controller 100. You may.

As such, the virtual drone simulator unit 520 may perform drone flight training using a virtual drone through preset 3D graphics, but collects an environment or image of a desired place to fly the virtual drone through this. Any action for this may be possible. To this end, the virtual drone simulator unit 520 may be equipped with a separate tool, and when a user wants to directly produce a desired 3D graphic, he/she selects a desired flight location and collects images of the desired location. This can be used to create and utilize 3D graphics. For example, if there is a place that separately sells images related to various flight places, it will be possible to collect images of a specific place and produce and utilize 3D graphics related to various flight environments.

The storage unit 530 may temporarily store various information or data processed under the control of the control unit 510 . Of course, the storage unit 530 may store various data in the form of a lookup table (LUT) and then output it under the control of the control unit 510 when the virtual drone simulator unit 520 requests it.

In addition to the above, the communication interface unit 500, the control unit 510, the virtual drone simulator unit 520, and the storage unit 530 of FIG. 5 may perform various operations, and other details have been sufficiently described above. , we would like to replace them with

Meanwhile, as another embodiment of the present invention, the controller 510 of FIG. 5 may include a CPU and a memory. The CPU and the memory may be formed as one-chip. The CPU includes a control circuit, an arithmetic unit (ALU), a command interpretation unit, a registry, and the like, and the memory may include a RAM. The control circuit can perform the control operation, the operation unit can perform the operation of binary bit information, the command interpretation unit can perform the operation of interpreting the high-level language into machine language and the machine language into high-level language, and the registry can be involved in software data storage. can As a result of the above configuration, when the simulator device 120' of FIG. 5 is initially driven or necessary, the program or algorithm stored in the virtual drone simulator unit 520 is stored in the memory and then executed, thereby rapidly increasing the operation processing speed. There will be.

6 is a flowchart illustrating a driving process of a drone manipulator binding system for a virtual drone training simulator according to an embodiment of the present invention.

6 together with FIG. 1 for convenience of explanation, the hub device 110 of FIG. 1 according to an embodiment of the present invention receives a control signal for controlling the virtual drone on the monitor screen from the drone manipulator 100 ( S600). Of course, prior to this, the drone manipulator 100 performs a pairing operation for registering the drone manipulator 100 and/or the hub device 110, and the virtual drone performs a 3D A graphic model may be preset. For example, the virtual drone includes a quadcopter, a hexacopter, an octacopter, etc. according to the number of wings, and each configuration and property may be set and stored. Information on the operation method of the drone controller 100 , that is, mode 1 or mode 2 may also be set as environment information.

In addition, the simulator device 120 sets flight environment data related to a flight environment in which the virtual drone is flown, converts the received control signal so that the set environment data is changed, and converts the output value of the converted control signal into a virtual machine. It binds to the drone and controls the movement of the virtual drone on the screen (S610).

For example, the drone controller 100 sets an operation method for mode 1 or mode 2, and receives control signals for pitch, roll, yaw, and throttle of the drone controller 100 received according to the operation method. . The simulator device 120 converts the control signal by applying, for example, a preset flight environment to the received control signal, and connects the converted control signal to the virtual drone. For example, since the virtual drone is a graphic moving on the screen, the simulator device 120 implements the converted control signal as an image. For example, when a motion occurs in the virtual drone, the motion is implemented in a unit frame of each image so that when an image is realized for a specified time, the motion is reflected in the virtual drone and displayed on the screen as an image.

In addition to the above, since the hub device 110 and the simulator device 120 can perform various operations, other detailed information will be substituted with the above contents.

7 is a flowchart illustrating a driving process of a wireless drone controller binding system for a virtual drone training simulator according to another embodiment of the present invention.

7 together with FIG. 1 for convenience of explanation, the hub device 110 of FIG. 1 , that is, the drone (wireless) manipulator 100 according to an embodiment of the present invention, is connected to the USB terminal of the simulator device 120 such as a PC. Mount (or connect) (S700).

Thereafter, a pairing operation is performed between the drone controller 100 and the controller signal reception and converter, that is, the hub device 110 (S710). Of course, the pairing operation may be set between the drone controller 100 and the PC, that is, the simulator device 120 via the hub device 110 .

The simulator device 120 executes the virtual drone control simulator software mounted therein (S720), and thereafter may perform an operation for setting the virtual drone training simulator software parameters (S730). Through this, property values (eg, weight, material, etc.) of the drone controller 100 or environment data related to the flight environment of the drone may be set. After performing the pairing operation, the virtual drone training simulator software must be executed to recognize the installed USB, that is, the hub device 110 , so that the software can prepare to accept the signal value of the remote controller. Set environment variables such as whether the operation method of the remote controller is mode 1 or mode 2 in the executed software.

Then, a transmission/reception operation of the drone radio controller operation signal is performed (S730). In other words, the drone manipulator 100 transmits a manipulation signal, and the simulator device 120 receives a corresponding manipulation signal of the drone manipulator 100 , that is, a control signal for controlling the virtual drone.

The simulator device 120 calculates the manipulation value of the received manipulation signal (S750). For example, the drone controller 100 may transmit a PWM signal in relation to a user's manipulation, and the hub device 110 may convert the signal into a PPM signal and transmit it to the simulator device 120 , and the simulator device 120 may convert the signal into a PPM signal. ) converts the corresponding PPM signal back to a PWM signal to determine the control information of the manipulation signal. In general, communication carries a control signal on a carrier wave (or a reference signal) and transmits it, so the control signal can be determined by subtracting the carrier signal from the received signal. This may be circuitry to obtain the control signal by passing a filter that filters the carrier in the received signal. For example, the manipulation signal detects the movement of the stick, and as a relative coordinate value, the coordinate value of the center region is set to (0, 0), and then the direction and the movement distance can be measured to provide the value. . Motion sensing may be performed in various ways by a direction sensor or a distance measuring sensor, and such a manipulation value is transmitted to the simulator device 120 as a control signal.

The simulator device 120 receives the signals for manipulating the drone manipulator 100 and calculates an output value to be applied to the motion of the virtual drone in the control value calculation unit 123a of the simulator, that is, a control value, and more precisely, a preset environment. After calculating the control value by further reflecting the data or attribute values related to the actual drone type, the calculated control value is applied to the movement of the virtual drone (S760). As mentioned above, it can be seen that the control values applied to the movement are realized and displayed as an image. For example, if the real drone or virtual drone is light, there will be a lot of shaking in the wind resistance, and if the real drone or the virtual drone is heavy, the shaking in the wind resistance will be small.

In this way, the user selects a virtual drone related to a specific drone sold in the market, and controls the virtual drone by reflecting the drone's attribute value or the environmental data of the place where the user wants to fly the drone in the real environment. By doing so, it will be possible to conduct realistic drone training. In particular, by performing the simulation in consideration of the real environment, users will be able to reduce trial and error due to drone flight even when put into the real environment.
