Description

Technical Field

[0001] The invention relates to the technical field of airport visual navigation lighting, in particular to a light box monitoring device for a navigation lighting system. Background Art

[0002] The airport navigation lighting system isolation transformer box, also known as the light box, is a barrel-shaped equipment installation box used to install an isolation transformer to supply power to front-end navigation lights and other navigation facilities.

[0003] The existing navigation light monitoring system mainly monitors the front-end navigation lights by monitoring the on-off status of the front-end navigation light power supply circuit to determine the fault of the light. When the isolation transformer has quality problems or aging, the output power fluctuates, and the light intensity of the front-end navigation light cannot meet the aircraft approach requirements, it is difficult to make a judgment. Although each light box must undergo a watertightness test before installation, the light boxes in low-lying areas of the earth surface area often have water intrusion into the light boxes as the rubber sealing ring ages. When the light box is flooded, the navigation light monitoring system can only detect the fault through the disconnection state of the light when it affects the normal use of the light, and cannot provide early warning. If sensor monitoring and other technologies are used to monitor the isolation transformer status, water intrusion in the light box, etc., it is difficult to implement network monitoring due to the large distribution area of ​​the light boxes in the airport, the distance from the tower and the duty platform of the lighting station, and the high construction cost of building a dedicated network communication link for small and medium-sized airports.
