Intelligent detection method of multi-fault airport navigational lamps based on two-way automatic communication

Navigational lighting aid systems are critical to ensuring the safety of aircraft operations. To ensure the lighting rate of lamps, the daily inspection and maintenance have become significant tasks for the airport. Enhancing airport intelligence and reducing the operational burden on airports are essential for promoting their rapid development. Therefore, we propose using power line carrier communication as the medium, employing two-way automatic communication technology to enable single-lamp intelligent detection. This method overcomes the shortcomings of the traditional single-lamp monitoring technology in terms of weak anti-interference capability and limited fault detection types. To verify the method's feasibility, we built an intelligent inspection system. The simulation experiment results show that the intelligent inspection system, established based on our proposed method, can accurately identify the lamp fault types and perform fault-lamp localization.
