Guided armed refers to a weapon equipped with a device that is guided by a particular method until the target or target is reached. Guided weapons allow precise target strikes by controlling the direction of flight, speed, etc. of the vehicle by the guided device.

Guidance arming is divided into command guidance, homing guidance, and navigational guidance. The instruction induction is a method of calculating an induction signal outside the induction armed and transmitting the induction arm to the induction armed, which corresponds to a wired command, a radio command, and a radar command. Homing induction is an induction method that searches for, captures, and tracks a target by a seeker built into the missile.

Conventionally, as illustrated in FIG. 1, data is exchanged between the arming management apparatus 20 (SMC) and the induction arming 10 according to the MIL-STD-1760E military communication standard. MIL-STD-1760E is a military communications standard established by the US Department of Defense, which defines technical design criteria such as signal degradation tolerance, modulation scheme, hardware operation, and electrical characteristics of US military communications systems.

However, such a conventional military communication standard transmits image data, audio data, target tracking data, and guidance data between the armed management device 20 (SMC) and the guided armed arm 10 through a wire, and the data is one-way and the electric and magnetic There are drawbacks that are susceptible to interference and easy to corrode. In addition, it is inconvenient to transmit image data, audio data, target tracking data, and guidance data using separate wires.

2 is a diagram illustrating an induction armed system for performing fiber channel communication between an induction armed and an armed management apparatus according to an embodiment of the present invention.

The guided weapon 10 refers to a weapon that is guided to a target until it reaches a target as a guided missile and is driven by a rocket, a jet engine, or the like as a guided missile. When image information is transmitted from the seeker of the missile head to the weapons management device, the weapons management device is a missile of a method of designating and directing a target. In the homing induction method of inducing a target to be reached in this manner, an image of the target is acquired and the target is tracked using the unique shape or spectral characteristics of the target. Typically, an apparatus for tracking a target by acquiring an image of the target is called an electro optical tracking system (EOTS). The electro-optical tracker includes an image acquisition unit that acquires an image, an image processing unit that processes the acquired image, and a target tracking unit that calculates an error between the guidance direction and the target based on the processed image. The information processed by the target tracking unit is transmitted to a store management computer (SMC) that controls the overall operation of the guided armed, and the armed management device controls the flight of the guided armed and transmits the guided armed to the guided armed as guide data. Make the guided weapon point towards the target.

Therefore, the guided armed 10 generates guided armed data generated through the target tracking, and can track and attack the target according to the guided data to induce the target tracking.

Arm management device 20 (SMC; Store Management Computer) is an arithmetic operation to receive the guided armed data from the guided armed, and to perform arithmetic processing operation to generate the guided data to guide tracking control by analyzing the trace route based on this. To this end, the arming management device is mounted on an armed aircraft such as an armed drone, and receives data such as image data, audio data, and target tracking data (hereinafter referred to as 'guided armed data') from the guided armed vehicle.

The arming management device 20 exchanges the guided armed data with the guided armed 10 through a fiber channel. The guided armed fired from the armed vehicle receives the guided armed data obtained from the armed vehicle through the fiber channel. The guide data is transmitted to the management device, and the induced data generated by the weapon management device is transmitted to the guided weapon through the fiber channel. Armed vehicles and guided weapons are connected by a fiber over a certain distance, so that guided armed data can be transmitted to the weapons management device through the fiber to a certain distance even if the guided weapon is fired from the armed vehicle.

In addition, the arming management device 20 performs a function of processing the guided armed data to transmit to the ground control center (not shown). For example, the image data is processed into a video image of a specific format and wireless RF transmission to the ground control center.

Fiber channel 30 is a wired communication channel for exchanging data through fiber, and has the advantages of simplicity of I / O channel, bidirectional communication with peripheral devices, and flexibility of the network. The fiber material of the fiber channel may be implemented in various forms such as twisted pair copper wire, fiber-optic cable, and the like. For reference, an example of a topology between devices through a fiber channel is shown in FIG. 3, where FIG. 3 (a) is a point-to-point method as a direct connection method and FIG. 3 (b) is a loop connection method. An Arbitrate Loop method, FIG. 3 (c) illustrates a switched fabric method which is a switch connection method.

Fiber Channel 30 is a high-speed interface capable of transmitting gigabit speeds.A full-duplex link (bidirectional) by two optical channels per link, 100 to 800 Mbps performance (ultra high speed) on a single link, and a distance of 10 km (long distance) ), Connector miniaturization (I / O channel simplicity), higher connectivity than existing multi-branch channels, and various interface commands for existing channel and network protocols.

Therefore, the embodiment of the present invention can increase transmission efficiency by transmitting induced armed data such as high resolution image data, audio data, and target tracking data generated by the sensor of the induced armed to the arming management device (SMC) through a fiber channel. . In addition, compared to the electric wire used for induction armed data transmission between the induction armed and the armed management device, it is more resistant to environmental noise (ambient electromagnetic) in the surroundings, and can improve transmission speed and bidirectional communication to improve transmission efficiency.
