Design on Distributed Fault Monitoring System for Navigation Lights

Article Preview

Abstract:

For the environment of using the navigation lights and its requirement, a distributed fault monitoring system on the navigation lights is designed. The three-layer structure with slave station and master station and Voyage Data Recorder is employed in the system, which can monitor broken wire fault, short circuit fault and power failure on navigation lights. The mature RS485 communication circuit is adopted in communication interface not only between the master and the slave, but also between the master and VDR (Voyage Data Recorder). The master station gets the information of all navigation lights from the slave stations, and sends these received data to VDR after being processed. The system has been successfully applied in practice, and can effectively monitor the state of the navigation lights and give the alarm information when in fault. In addition, the monitoring system can quickly and accurately trace the fault position and type, so the navigation lights can be maintain timely.
