Design of Ship Navigation Light Controller Based on STC Microcontroller
The conventional controllers for ship navigation lights and signal lights locate in a mutual circuit with the main circuit.They usually have no open circuit protection,rely on fuses for short circuit protection,use virtual circuits con-trolled by series switches of main circuits with the indicator lamp connected in parallel at both ends of detection resistance. This makes the controllers highly electricity consuming,easily overheating,and fire risky.This work hence tried to ad-dress the aforementioned defect by designing a navigation light control system which uses STC microcontroller as the con-trol chip.The control module is separated from the actuation module,and communicates with the latter by serial port. This avoids the use of power lines in accordance in number with lamps and lanterns,thereby simplifying wiring,facilita-ting maintenance,lowering manufacturing cost,and promoting safety and reliability.
