EMERGENT STOP DEVICE FOR SMALL-SIZED VESSEL

摘要

PURPOSE:To prevent the stop of a vessel by the erroneous operation due to the hindrance electric waves by installing a detecting means for the hindrance electric waves and setting the emergent stop function into rest, when the electric wave signals supplied from a transmitter are not received and the hindrance electric waves are detected. CONSTITUTION:A transmitter 1 code-converts the prescribed signals by using an encoder 11, and transmits the electric wave signals from a built-in bar antenna 14 through an oscillator 12 and an amplifier 13. A decoder 28 discriminates if the output signal of the low frequency amplifier 27 of a receiver 2 accords with the prescribed signal to be transmitted from the transmitter 1 or not, and when accordance is judged, a discrimination signal S is outputted from the decoder 28 into a control part 29. Further, a high frequency detector 31 for detecting the hindrance electric wave of the receiver 2 outputs a detection signal R, and the control part 29 judges anomaly from the combination of the discrimination signal S and two kinds of detection signals R and I, and outputs an anomaly signal C and emergently stops an engine.
