Development of a Model of the TCAS Autonomous Diagnostic System Using Non-contact Current Sensors

In the work, the problem associated with a false alarm of the TCAS system is investigated when there is not a single conflicting aircraft in the system’s coverage area. The article analyzes the existing problem and ways to solve it using non-contact current sensors for autonomous diagnostics of the TCAS system. As a solution to the problem, a model of autonomous diagnostics with non-contact current sensors is proposed. As a result, it is shown that autonomous diagnostics of the TCAS system can be implemented using a Hall sensor and a Rogowski coil, which allow non-contact monitoring of operating currents, which makes it possible to detect and eliminate false alarms of the system.
