Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air traffic control system for an unmanned aerial vehicle (UAV) using a commercial mobile communication network, and more particularly to a universal subscriber identity module (USIM) (UAV) based on a commercial mobile communication network for flight control of small UAVs classified by ID code, it is possible to overcome limitations of industrial scientific and medical (ISM) bandwidth radio frequency, And techniques for performing control.
UAV means an aircraft capable of being operated without a pilot on board, and can perform various tasks such as observation, exploration, combat, reconnaissance and surveillance. Conventional UAVs often use pilots to perform remote operations on the ground because of the use of high-priced, high-performance reconnaissance equipment alone. However, in order to effectively perform complex missions, a number of small UAVs The need to utilize it has increased. The most important part of the small UAV operation purpose is the monitoring task, which involves the aerial image capturing process and it can control the air traffic control system in addition to the jurisdiction system of the process of receiving the aerial image data taken by many small UAVs An integrated system is essential. A satellite communication system is a typical example of a broadband communication system capable of smoothly receiving the aviation image data and performing air traffic control for a plurality of small UAVs. However, the satellite communication system is focused on the problem of cost and most of the applications related to the national defense industry or national defense industry. Therefore, communication method which can be cost competitive in civilian field and relatively easy to approach from the viewpoint of operator is to use commercial mobile communication network. Since the current state of commercial mobile communication network construction and operation technology is leading to the highest level in the world, it can be the basis of small air traffic control system for UAV and can play a role as a bridgehead for entry into the MNC market. If the demand for small UAV air traffic control using the commercial mobile communication network is increased, it is likely to cause congestion with the existing air traffic control operating system. Therefore, it is necessary to develop technology for operating environment and structure to prepare for future changes in the navigation environment.
Air traffic control refers to the task of constantly communicating with an aircraft in flight to control takeoff and landing of the aircraft and prevent collision between aircraft to induce safe flight. At present, air traffic control is performed depending on the voice communication between the ground control station and the aircraft, the ground radar system, and the transponder. However, small UAVs can not be controlled by a general air traffic control system for the following reasons. First, high-performance radar and voice communication equipment is basically expensive, and it is technically very difficult not only to install it in a small UAV of 10 ~ 20kg class, which is a relatively low cost lightweight water form, but also to take off. Second, because of the limitations described above, high-performance radar and voice communications equipment can not be used, which limits the systematic tracking and management of small UAVs in flight. Third, it is technically difficult to perform voice communication using UHF and VHF band frequencies between a small UAV flying in a low altitude region of 100 ~ 200m or less and a remote station.
If the commercialization of small UAVs accelerates, there is a high possibility that the problem of air traffic control of small UAVs will become serious. Among the technical problems that are expected to face are technical issues such as restrictions on flight permits of small UAVs, flight status, flight area allocation, limited scientific bandwidth of the ISM band (radio frequency superposition problem, Identification of the responsibility of small UAV operators in case of occurrence, and countermeasures against collision between small UAVs in operation. Therefore, a systematic and efficient air traffic control system for small UAV operation and control is required to solve the above problems. For air traffic control of a small UAV, the following items should be considered first. First, the ISM band radio frequency should not be used. Second, it is possible to fly outside the visible range and the flight situation should be monitored in real time. Third, stable communication and control should be possible at low altitudes. Fourth, many small UAVs in flight must have their own identifiers, and the controller should be able to grasp flight information in real time, such as flight altitude, speed and location, as well as each small UAV flight identified by a unique identifier . Fourth, the controller should be able to provide the flight information of the possible flying objects to each small UAV, or to provide an avoidance path for avoiding collision.
Similar prior arts for building a compact UAV air traffic control system using the commercial mobile communication network described above include those described in Korean Patent Application No. 10-1436555, No. 10-1073042, No. 10-1472392, No. 10-2013-0058922 , 10-2011-0003986. However, in the past, the problem of identifying codes for a number of small UAVs has been solved, and there has not been provided a technique for avoiding frequency duplication between unmanned systems using a commercial mobile communication network, capable of flying outside the visible range, and monitoring flight status.
The present invention aims to satisfy the technical needs required from the background of the above-mentioned invention.
Specifically, it is an object of the present invention to avoid the problem of overlapping with the existing ISM band radio frequency by using the existing commercial mobile communication network as a means of operating the air traffic control system for a plurality of small UAVs, And to provide an integrated small UAV air traffic control system capable of flying out of the street, monitoring flight status in real time, issuing control commands, and acquiring aviation images and flight information data shot in a number of small UAVs .

In addition, by attaching the USIM card to each small UAV, it is possible to solve the identification code problem that occurs when a plurality of small UAVs are operated, and it is easy to send the emergency avoidance command to a plurality of small UAVs in case of similar situations during flight.
