Description

Technical field

[0001] The invention relates to a maritime navigation device for providing sound navigation signals. More specifically, the present invention relates to an economical controller for automatically controlling the sound navigation signal generated by the ship horn and providing advance signal warning. Background technique

[0002] When operating a navigating vessel under conditions of limited visibility (such as fog), the International-Inland Navigation Rule (Navigation Rule International-Inland), COMDTINST M16672.2D (commonly referred to as 72COLREGS or simply referred to as COLREGS) is subject to the 35- Among the sound signals in the case of limited visibility, audible signals are required to be sent out according to a predetermined plan. Usually, these audible signals are generated through the ship's navigation horn, siren, or special fog signal. For example, a motorized vessel that is more than 12 meters in length is required to emit a "one long beep" horn sign...

Embodiment Construction

[0028] Now refer to the attached drawings, especially figure 1 , Which represents an exemplary embodiment of the present invention, and this embodiment has a horn controller denoted by reference numeral 10. The controller 10 preferably has an installed detector 22, a user interface with a mode selector 14, a microprocessor 12 with a random number generator 20, and a timing system 18. The controller 10 works in cooperation with the ship's horn, siren, and / or special fog signal 16 to adjustably and / or automatically emit the sound of the horn signal mode. The controller 10 preferably cooperates with the microprocessor 12 to selectively make the speaker 16 emit sound according to a designated mode or setting. The time period between horn signals can be changed according to the delay time inserted by the random number generator 20.

[0029] The activation of the controller 10 depends on the type of installation used. For example, if the installation type uses a parallel signal (type A...
