Water erosion monitoring system and control method for isolation transformer of airport navigation lights

Abstract

The invention relates to a water erosion monitoring system and control method for an isolating transformer of an airport aid-to-navigation lamp. The system comprises an upper computer system and a plurality of spot units which are connected with the upper computer system in a wireless manner. The water erosion monitoring system and control method for the isolating transformer of the airport aid-to-navigation lamp can detect the water inflowing situation of the isolating transformer in time, and report the situation in real time so as to prevent the isolating transformer from working in an accumulated water situation for a long time; by utilizing an existing aid-to-navigation lamp light system, the system can supply power for a detection module through a power supply conversion unit, thus realizing the automatic real-time water level and water temperature acquisition and fault positioning of the isolating transformer and achieves the functions of remotely monitoring water erosion by a wireless transmission communication manner and the like. The device can be seamlessly engaged with the existing aid-to-navigation lamp light system, the maintenance efficiency of the aid-to-navigation lamp light system can be improved, and the manpower and material resource cost can be lowered.

[0002] In the airport navigation lighting circuit, the isolation transformer is one of the important components of the navigation lighting power supply and dimming system. Its primary winding is in a series circuit, and the current of the series circuit is relatively constant. Each light level is set; and its secondary winding is used in parallel to supply power to navigation aids; each isolation transformer is connected to each other through a pair of single-stage plugs and a bipolar socket to form a series main circuit and a parallel circuit. Aviation lighting power supply network; in actual airport operation, several isolation transformers are usually placed in the isolation transformer box on both sides of the runway, but due to construction and other factors, the isolation transformer box is prone to water ingress in rainy weather, making the isolation transformer Long-term operation under the condition of accumulated water will cause the isolation transformer connector to be corroded and damaged, resulting in line failure, and even open or short circuit of the lamps, which will affect the normal operation of the navigation aid lighting system, thereby affecting the operational safety of the aircraft

[0003] At present, for the water erosion detection of isolation transformers, most of them adopt the method of manual inspection and regular replacement; there are many problems in the method of manual inspection and regular replacement: on the one hand, regular replacement of devices causes waste of resources; on the other hand, manual inspection consumes a lot of manpower There are a large number of resource and navigation light isolation transformers, and there are inevitably human errors; finally, the most important thing is that the isolation transformers with water erosion cannot be detected in real time, and the problems can be found and solved in time, leaving a safety hazard
