Study of AIS beacon control system based on ARM

摘要

Beacon is an important guarantee for the navigation safety, and if its equipments are damaged or lost, it will directly affect the safety of ships at sea. AIS beacon designed in this paper is based on ARM7 and AIS receiver. The system achieves to monitor and display the beacon voltage. It designs the algorithm to predict potential collision risk before the accident, and reports to the AIS center so as to assist finding the incident ship. The test results show that AIS beacon can completely receive all the information from the around ship and realize collision avoidance.
