| Due to the complexity of the marine environment, coupled with the gradual expansion of the scope and depth of fishing operations, the safety of underwater monitoring platform has formed a great threat. And in the implementation of the underwater platform for the recovery process at sea, bad sea conditions, sea fog, sea light reflection and other unfavorable factors are all caused great trouble to the recycling process, once the platform surfaced after the drift range will face the risk of loss, Causing great economic losses. Based on the Beidou positioning navigation system and the pressure detection circuit, this paper designs and realizes a satellite positioning beacon system which can be used in the underwater platform for accidental water alarm and real-time positioning after the effluent. After several applications, the performance is stable and reliable. |
