The invention relates to an improved signalling system for the transmission of messages by means of light signals, particularly suitable as a means of communication between naval ships. According to the invention, the signalling system is to a high degree automized by entering the message in a data entry system as a fragment of intelligible text, by coding and automatically sending the message. The light signals of the signalling lamp are received by a receiving apparatus, for instance embodied as a TV-camera. The light signals are extracted from the TV-image and are stored as a bit string. The bit string is subsequently converted into intelligible text. The receiving apparatus and signalling lamp are preferably mounted on a joint, stabilized platform.

L'invention concerne un système de signalisation amélioré conçu pour la transmission de messages par signaux lumineux, un moyen de communication particulièrement approprié entre les bateaux. Le système de signalisation, dont le niveau d'automatisation est élevé, permet d'entrer le message dans un système d'entrée de données en tant que fragment de texte intelligible, de le coder et de l'envoyer. Les signaux lumineux de la lampe de signalisation sont reçus par un appareil de réception représenté, par exemple, par une caméra de télévision. Les signaux lumineux sont extraits de l'image télévisuelle et stockés en tant que chaîne binaire. La chaîne binaire est par la suite convertie en texte intelligible. L'appareil de réception et la lampe de signalisation sont, de préférence, montés sur une plate-forme commune stable.
