A marine broadcasting system with a failure diagnosis module and failure diagnosis method

摘要

The present invention relates to a marine broadcasting system and a fault diagnosis method equipped with a fault diagnosis module, which comprises a main controller for controlling a broadcasting system, an input unit for inputting a voice signal, an amplifier for amplifying a voice signal inputted from the input unit, An interface board for distributing the amplified voice signal from the amplifier to each speaker under the control of the main controller, at least one speaker for reproducing the amplified voice signal from the amplifier, and a main power supply unit for supplying power to the components, And an emergency power supply unit for supplying a substitute electric power when the main power supply unit fails, A test point installed in each component of the marine broadcasting system unit for detecting presence / absence of input / output of a signal transmitted / outputted to each component, a diagnostic device interface for collecting information sensed from each test point, And a diagnosing device control unit for inputting or outputting a signal and judging the information collected from the diagnostic device interface to perform a trouble diagnosis. The apparatus for diagnosing malfunction of a marine broadcasting system according to claim 1, The integrated diagnosis control unit may include detecting a signal undetected portion of each of the test points and checking whether a signal input of a neighboring test point having a signal arrival order earlier than the test point of the undetected portion is detected in the signal line of the undetected portion Step, test point with signal validated and phase The method comprising the steps of: determining an abnormal part between test points of a non-signal detecting part; reporting the abnormal parts and signal undetected test points to provide a fault diagnosis module to the user; And provides a fault diagnosis method of the system.
