Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in more detail. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you. Wherein like reference numerals refer to like elements throughout.

1 is a view showing the operation of the armed drone under the control of the ground control center according to an embodiment of the present invention.

The ground control center 10 is a ground control station that exchanges flight and arming of the armed drone 20 through a wireless data link. The ground control center 10 transmits flight control data to the armed drone, and also transmits target attack control data such as weapon mounting control data, target aiming control data, and weapon launch control data. In addition, the ground control center 10 receives the image information data and operation information data observed in the armed drone 20 and displays it on the screen of the ground control center, the ground control personnel to check this to perform the control of the appropriate armed drone To help.

Armed drone 20 is an armed aircraft having the ability to perform operations without a pilot is a vehicle performing a mission by radio control with the ground control center. Armed drones do not require a boarding pilot, so there is no human loss due to combat or aircraft crash, and they are not subject to the physiology or psychological state of the boarding pilots, so they can maneuver or operate in harsh flight conditions that are impossible with an armed drone. In addition, since the equipment and equipment necessary for the pilot on board are not necessary, the aircraft can be manufactured in a very small and light weight.

Armed drone 20 transmits the flight information to the ground control center 10 to display on the screen of the ground control center, it is possible to remote control. Therefore, the aircraft's electronic equipment includes essential wireless equipment that connects the aircraft to ground control centers, electronic equipment necessary for measuring and controlling aircraft conditions, and mission equipment required for mission execution, and ground equipment necessary for maneuvering and operating drones. Etc. are required.

The armed drone 20 performs operations such as flight control, weapon mounting, target aiming, weapon firing, etc. according to target attack control through a wireless data link of the ground control center 10.

By the way, when the data link between the ground control center 10 and the armed drone 20 is broken, an operation such as undesired armed operation and weapon firing may be performed. In the state where the data link between the ground control center and the armed drone is broken, since the armed drone cannot be controlled, an operation such as unintended firing of the armed drone may be performed. Unintended firing of weapons can cause massive damage, including killing civilians. Unintended weapon firing can also occur in the event of a gas defect such as damage to the aircraft of an armed drone.

In the embodiment of the present invention, when the cause of disarming, which causes the disarmament of the armed drone, occurs, the disarming of the armed drone is released to block the possibility of unintended firing of the weapon. The cause of disarming was determined to be the cause of disarming when a data link disconnection or a gas defect occurred. The data link disconnection refers to a case in which the data link is disconnected for more than the threshold time N [ms] or the number of disconnections of the data link exceeds the threshold number M times or more. Aircraft defects also refer to cases in which the flight is out of normal range or a malfunction of the aircraft components occurs. If the cause of disarming such as data link disconnection or gas defect occurs as described above, disarming of the armed drone is released to block the possibility of weapon firing.

2 is a block diagram of an armed drone according to an embodiment of the present invention.

The data link unit 21 performs a wireless data link with the ground control center. The data link unit of the armed drone receives flight control data, target attack control data (including weapon-mounted control data, target aiming control data, and weapons launch control data) from the ground control center via RF communication specified by the specification. In addition, the armed drone transmits the video information data and operation information data observed in the armed drone to the ground control center. To this end, the data link unit converts a PPM (Pulse Position Modulation) signal into a DCS (Digital Control Signal) and configures a method of transmitting it to a communication modem to enable more stable and various information transmission over a long distance. For example, a communication modem mounted on an armed drone, such as a bomber, uses a frequency band according to a setting in the 902 to 928 MHz (FHSS) band. A self-diagnosis program can be built in that detects frequencies such as modem distance and noise intensity in the same frequency band. In addition, dual communication system is used to cope with abnormal transmission / reception status at short distance during take-off and landing by using R / C transceiver of 2.4GHz band that has the same signal system as control signal transmitted from communication modem to increase communication stability. Can be configured.

The data link monitoring unit 22 monitors in real time the connection state between the armed drone and the data link with the ground control center to determine whether the data link is disconnected. The data link disconnection determination counts the time and number of times the data link between the armed drone and the ground control center is broken, and determines that the data link is disconnected when this condition satisfies a predetermined condition. For example, if the armed drone does not receive an acknowledgment message such as an acknowledgment (ACK) from the ground control center after transmitting data to the ground control center, it is determined that the data link is disconnected. In addition, specific information data is periodically received from the ground control center, and even if the information data is not received even after exceeding a predetermined time (for example, the threshold time N [ms]), the data link with the ground control center is disconnected. I think it is. It is also determined that the data link is disconnected even when the data link with the ground control center exceeds the threshold number M times. If it is determined that the data link is disconnected, the armed management is notified of the data link disconnection. The threshold time N [ms] is a preset value, and the threshold number M times is also a preset value.

The gas defect monitoring unit 23 detects the state of the gas of the armed drone in real time through a detection sensor, and determines that the gas defect is above a preset threshold. For example, if the flight path of the armed drone is out of a preset range or the cover of the weapon compartment of the armed drone is open, it is determined as a gas defect. If it is determined that the aircraft is defective, the Armed Management Unit shall be notified of the defect.

The flight control unit 26 performs a function of controlling the flight of the armed drone, and controls the flight according to the navigation information previously input or transmitted from the ground control center. Flight control controls the flight of the drone, such as horizontal control and vertical control. The flight control unit notifies the armed management unit that there is an error in flight control and navigation information when flight control is not performed as desired due to a gas defect or when there is wrong navigation information such as a flight to a no-fly zone.

The arming management unit 25 performs a dearming operation of the armed drone when it is determined that the data link is disconnected from the ground control center, the aircraft defect of the armed drone, the flight control abnormality and the navigation information abnormality.

Disarmament of an armed drone cuts off weapon firing power or disarms a weapon. The weapon firing power off can be achieved by shutting off the main power prime power for the arming to operate basically, the squib power which is the power required for firing and dropping the arming. In addition, the weapon can be unloaded by placing a weapon such as a missile in a storage space without being mounted on a projectile, or by closing a weapon discharge door. The armed management may also disarm following the procedures recorded in the disarmament procedure database. The disarming countermeasure (manual) assigned to it in accordance with the situation of data link disconnection or gas defect is extracted from the disarming procedure database and the disarming according to the countermeasure is performed.

The disarming procedure database 24 is a DB in which a disarming procedure for disarming the armed drone is registered and stored according to a data link disconnection, a gas defect, or the like. Disarmament Procedures The database registers examples of various disarmament procedures, for example, to disconnect the armed squib power in the case of a data link disconnection, and to prime the armed prime power if there are more than M disconnections. In the case of a gas fault above flight control, it cuts off the prime power and squib power of the armed, and if there is a flight condition of the armed drone from navigation information, it cuts off the armed prime power and squib power. In the event of a gas defect, which is a malfunction of the aircraft's aircraft, the disarming procedure for shutting off the squib power and closing the weapon release door is registered. The disarmament procedure database may include a hard disk, a flash memory, a compact flash card, a secure digital card, a smart card, and an MMC card. A module capable of inputting / outputting information such as a media card or a memory stick may be provided inside the device, or may be provided in a separate device.

3 is a flowchart illustrating a process of releasing the arming according to the state of the armed drone according to an embodiment of the present invention.

The armed drone maintains the arming of the weapon is mounted in the dropping position while in flight (S31). It is determined whether the cause of disarming, which is a fulfillment condition for releasing the arming, occurs during the flight of the armed drone (S32).

The disarming causes include data link disconnection, gas component defects, flight control abnormalities and navigation information abnormalities indicating that the data link with the ground control center is disconnected. Data link disconnection refers to the time when the data link between the armed drone and the ground control center is broken, and the number of times it is broken, when this condition satisfies a predetermined condition. For example, if the armed drone does not receive an acknowledgment message such as an acknowledgment (ACK) from the ground control center after transmitting data to the ground control center, it is determined that the data link is disconnected. In addition, specific information data is periodically received from the ground control center, and the data link with the ground control center is disconnected even when the information data is not received even after exceeding a predetermined time (for example, the threshold time N [ms]). I think it is. In addition, even if the disconnection of the data link with the ground control center exceeds the preset threshold number of times M, it is determined that the data link is disconnected.

In addition, the gas defect refers to an abnormal state of the gas state of the armed drone, and detects the state of the gas of the armed drone in real time through a detection sensor, and determines that the gas defect if the predetermined threshold value or more. For example, if the flight path of the armed drone is out of a preset range or the cover of the weapon compartment of the armed drone is open, it is determined as a gas defect. In addition, flight control abnormalities and navigation information abnormalities refer to wrong navigation information such as flight control not performed as desired or flight to a no-fly zone due to gas defects.

As a result of determining whether the cause of disarming has occurred, when the cause of disarming occurs, a process of disarming the armed drone is performed according to the disarming procedure (S33). Before disarming and maintaining the arming, the disarmament procedures that must be performed on the ground for each disarmament cause must be registered in the disarmament manual database in advance, and the disarmament procedures for disarmament caused by disarmament will be extracted and used.

The disarmament procedure disarms the armed drone according to the disarming procedure extracted and extracted from the disarmament procedure database that stores the disarmament procedure to be performed for each disarmament cause. As a disarming procedure for each cause of disarming, when the data link is disconnected, the armed squib power is cut off. When the data link is disconnected more than M times, the armed prime power is shut off. In the case of the armed prime power and squib power is cut off, if there is a flight condition of the armed drone from the navigation information, the armed prime power and squib power is cut off, and the aircraft defect is a device malfunction of the aircraft of the armed drone. If this occurs, the squib power shut-off and weapon dropping door can be closed.

On the other hand, the cause of disarming has a data link disconnection, a gas component defect, flight control abnormality, and navigation information abnormality. From the other point of view, the reason for disarming will be described with reference to FIG. 4.

From the point of view of human damage, the causes of disarmament may include the following causes of gas crash and armed misfires.

1) Cause of gas crash

A. Data link corruption: If the drone is controlled by the data link rather than flying on its own, there is a possibility that the data link may fall if it is broken. If the drone falls, gas and armed explosions are expected to damage allied troops and civilians.

N. Flight control function failure: If there is a problem with the flight control function, there is a possibility of aircraft crash. If the drone falls, gas and armed explosions are expected to damage allied troops and civilians.

-Terrestrial Control Command Error: If there is an error in the ground control function, there is a possibility of aircraft crash due to incorrect flight control command transmission. If the drone falls, gas and armed explosions are expected to damage allied troops and civilians.

-Flight control computer error: The flight control computer controls the drone by command of the ground body. If there is a problem with the flight control computer, there is a possibility of aircraft crash. If the drone falls, gas and armed explosions are expected to damage allied troops and civilians.

-Disturbance: If the drone fails to fly normally due to disturbance, there is a possibility of aircraft crash. If the drone falls, gas and armed explosions are expected to damage allied troops and civilians.

Above CG: Failure to maintain the Center of Gravity (CG) could result in a gas crash. In the event of a drone crash, aircraft and armed explosions are expected to damage allied troops and civilians. Above Internal Load CG If there is a problem with the internal load CG, there is a possibility of a gas fall. If the drone falls, gas and armed explosions are expected to damage allied troops and civilians. In the case of an external load CG or more, there is a possibility of a gas fall if an abnormality occurs in the CG of the external load. If the drone falls, gas and armed explosions are expected to damage allied troops and civilians. Above the Pylon CG, there is a possibility of an aircraft crash if the weapon mounted on the pylon ignores the CG and fires. If the drone falls, gas and armed explosions are expected to damage allied troops and civilians.

C. Pilot operation error: There is a possibility of a aircraft crash due to a ground maneuvering mistake. If the drone falls, gas and armed explosions are expected to damage allied troops and civilians.

D. Gas damage: Gas damage may occur due to gas damage. If the drone falls, gas and armed explosions are expected to damage allied troops and civilians.

-Hit: When the drone is hit, gas damage occurs and there is a possibility of gas fall. If the drone falls, gas and armed explosions are expected to damage allied troops and civilians.

Gas Defect: Gas damage may occur if gas damage occurs due to gas defect. Operational damages to friendly troops and civilians are expected due to gas and armed explosions.

Armed Explosion: If a mounted weapon explodes while being mounted on the aircraft by a certain factor, there is a possibility of a gas crash. In the event of a drone crash, additional explosions of gas and unexploded armed forces are expected to damage allied troops and civilians. In the case of armed interference, there is a possibility that the drone may explode due to the effects of other armed weapons when the drone is equipped with a drone. In the event of a drone crash, additional explosions of gas and unexploded armed forces are expected to damage allied troops and civilians. In the case of armed control deficiencies, the control to fire the arm may fail, causing the armed to explode in the aircraft. In this case, there is a possibility of a gas crash. In the event of a drone crash, additional explosions of gas and unexploded armed forces are expected to damage allied troops and civilians. In case of SMC S / W error, there are BSP, OS, and application S / W defects.The SMC W / M Malfunction in charge of arming management and control judges the unsafe state as normal. Armed firing can be performed. Unsafe armed firing can result in drone falls due to gas damage. In the event of a drone crash, additional explosions of gas and unexploded armed forces are expected to damage allied troops and civilians. In addition, SMC H / W defects include armed management I / O defects, general I / O defects, armed control module defects, VPX switch defects, power module defects, transition module defects, and back plane defects. Malfunction of HW can cause unwanted firing commands. In this case, if the aircraft does not meet the conditions for safe launch, drones may be caused by gas damage. In the event of a drone crash, additional explosions of gas and unexploded armed forces are expected to damage allied troops and civilians.

2) Causes of armed misfire

A. Pilot Manipulation Errors: Armed fire can be caused by ground maneuvering errors. In this case, damage to friendly troops and civilians can be expected.

N. SMC operation error: Malfunction of the SMC, which is in charge of arming management and control, can cause an armed misfire. In this case, damage to friendly troops and civilians is expected.
