Conventional ship sailing on the sea must comply with international Code of Signals, whether it is the international maritime signal flag, flag semaphore, voice, light and radio, etc., are all complicated operation, human error, time consuming lead to communication problems. In order to improve the above shortcomings, the product will be the searchlight on the ship changed to high brightness, low-power consumption of LED, to reduce the ship＇s electricity consumption.
The light source of LED compose of red and green colors to deliver the signal. Transmitter can choose the Morse code or ASCII code by the human-machine interface, and the message is transmitted to the LED color and the length of ”on/off” time. Receiver is the use of CCD image sensor to receive the light signal of LED, and then through the software of receiver to identify the color, the length of ”on/off” time of light, translated into the true transmission of the signal.
