Problems solved by technology
It is a normal flight work scenario for military aircraft to maintain a small distance and fly at close range. Its close approach is a flight mode recognized and expected by both pilots and ground controllers. Frequent audio and video traffic warnings and decisive warnings are generated to a certain extent. It will distract the pilot's attention, cause the pilot to feel nervous, and increase his work pressure. Frequent warnings for a long time will reduce the pilot's sensitivity to TCAS warnings. It is beneficial for pilots to respond quickly, thereby increasing the probability of collision accidents
In addition, the broadcast of decisive warnings to the ground will also cause unnecessary interference to the controller
In short, since the existing TCAS design does not take into account the identity confirmation of short-distance targets and the removal of identity when leaving, unnecessary alarms are the shortcomings of the existing technology

Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings.
[0034]The system of the present embodiment designs a designated mode on the basis of the original working system of TCAS, and when the system works in the designated mode moment, the designated aircraft is based on the designated ICAO 24Bit aircraft address (uniqueness, one code for one machine) , in the early stage of the designation formation process, the pilot confirms the target within the designation through the dedicated display interface and dedicated control components, the warning logic of the TCAS designation recognizes the designation tag information, and does not generate traffic (TA) and decision when the designation mode warning is processed (RA) warning. The detection of the designated tag is performed once per second. When the designation is dismissed or the target is pushed out of the designation, the pilot will control again, release the designated ta...

The invention relates to the technical field of airborne collision avoidance, and discloses a TCAS specific target designation and alarm system. A TCAS designated working mode is provided in a targeted mode, and an aircraft can select between a designated working mode and a non-designated working mode. When the aircraft works in the designated mode, the aircraft in the designated target does not start a conventional anti-collision warning function, but enters a short-distance warning mode; and meanwhile, the complete TCAS function for a non-designated target aircraft is reserved, and monitoring and alarming of the TCAS of the designated aircraft on the specified external target are not influenced when the system works in the designated mode. In addition, the aircraft can quit from the designated mode through control selection, can recover the working state of normal independent flight and can start an anti-collision function. The TCAS specific target designation and alarm system is suitable for designated flight of a plurality of TCAS aircrafts, eliminates unnecessary interference voice and display alarm of aircrafts in a designated unit, and has a short-distance alarm function; and meanwhile, the situation awareness and alarm capability of the TCAS to the specified external target in the designated unit is maintained.
Description
technical field [0001] The invention relates to the technical field of airborne collision avoidance, in particular to a TCAS specific target designation and warning system. Background technique [0002] Airborne Collision Avoidance System (ACAS-Airborne Collision Avoidance System, also known as TCAS-Traffic Alert and Collision Avoidance System), currently used in military and civil aviation is generally TCASII type collision avoidance system, which can provide Traffic Alert (TA) and Decision Alert ( RA). TCAS is an essential device to prevent dangerous approaches and collisions of aircraft in the air, and it can work independently of the ground traffic control system. The function and performance index of the system shall meet the minimum performance standard of RTCA / DO185B. The system is mainly used to provide air safety separation guarantee for aircraft, and uses secondary radar to detect approaching aircraft in the nearby airspace. When necessary, it reminds pilots to t...
