Description

Technical Field

[0001] This utility model relates to the field of obstacle light technology, specifically an obstacle light data transmission control circuit. Background Technology

[0002] Obstruction lights, also known as navigational lighting equipment, are special lights used to identify obstacles. Belonging to the navigational lighting equipment industry, aviation obstruction lights are a specific type of light within this category. They are often installed on the tops of commercial buildings to serve as a warning and prevent aircraft from colliding with the buildings during flight. Obstruction lights generally have built-in data transmission units that transmit obstruction light data to a remote data center on a host computer. This necessitates the installation of an obstruction light data transmission control circuit within the obstruction light itself. Existing obstruction light data transmission control circuits have relatively simple communication methods. Furthermore, the obstruction light must simultaneously transmit its own data while receiving information from the host computer, resulting in slow transmission speeds. In addition, obstruction light data transmission suffers from poor signal stability; when subjected to signal interference, it cannot promptly transmit information from the lower-level machine to the upper-level machine. To address these issues, the inventors designed an obstruction light data transmission control circuit. Utility Model Content
