Description

Technical Field

[0001] This utility model relates to the field of microcontrollers, specifically to a circuit for simulating real-time airport navigation lights. Background Technology

[0002] In airport navigation lighting system operation and maintenance training, traditional employee safety training models generally suffer from technical bottlenecks such as a disconnect between theory and practice and insufficient realism in simulated scenarios. Existing training largely relies on two-dimensional drawings or static model demonstrations, lacking the ability to dynamically simulate actual lighting layouts (such as runway, taxiway, and apron lighting circuits). This makes it difficult for employees to intuitively understand the relationship between lighting control logic (such as five-level light level adjustment and sequential flash mechanism) and equipment spatial distribution. For example, traditional teaching materials cannot display the dynamic changes in current and light level status of each circuit in real time, nor can they simulate abnormal lighting scenarios caused by misoperation, resulting in employees lacking practical experience in actual emergency response. Furthermore, traditional training tools lack visual annotation functions for equipment model specifications, technical parameters, and installation locations. Technicians must spend a significant amount of time memorizing abstract data, making it difficult to quickly locate problem points during troubleshooting, significantly reducing training efficiency and practicality.

[0073] This invention not only accurately reproduces the navigation lighting layout of core areas such as airport runways, taxiways, and aprons, but also incorporates several innovative elements. Using C language programming technology, the microcontroller motherboard is programmed, along with a voice control module protocol. The input and output of each loop's single-side unit are controlled via the 485 bus protocol. Each loop displays its corresponding light level and current through a digital tube, enabling control of nine lighting loops in the area. The light level of each loop is controlled by diodes. A separate program is written for the sequential flashing lights, allowing 24 LEDs to sequentially illuminate and de-illuminate from far to near each second, while simultaneously outputting the corresponding light level's current. The control plan not only has voice functionality but also manual control, allowing individual switching of each loop. Interlocks exist between light levels 1-5, ensuring that only one light level can be activated per loop at a time. Voice control and manual control are also interlocked in both program and hardware to prevent accidental activation of lights. The simulated control box broadcasts real-time light status information and provides a simulated demonstration of five precise brightness levels, offering unprecedented convenience for emergency drills and routine maintenance. In addition, the floor plan also details the model specifications, technical parameters and installation locations of various lighting equipment, providing strong support for technicians to quickly locate problems and implement precise solutions.
