| In recent years, with the rapid development of the shipping economy, China’s coastal ports in the heavy traffic, shipping regulation increasing difficulty. Construction ship, sand carrier, especially small boat often through the channel, due to "nameless", they are often "impassability, called", maritime sector for this type of ship mainly through on-site management. But the cost is high, the patrol boats keeping traffic order and does not have the characteristics of persistence, so when a patrol boats come they disappeared,patrol boats went they appeared again. How to use advanced and low-cost equipment to establish a long-term supervision mechanism, has become a hot topic. Study on Small Boats Monitoring System in this case, will has great economic significance of reality for maintain the normal port transportation, guarantees the port production efficiency.Caused by the dense ship and port facilities, on the one hand, radar monitoring can not be implemented within the port on the boat; On the other hand, this kind of boat is not a SOLAS deadline ship with AIS, and it is not mandatory installation of expensive AIS equipment. So we must use regulation technology innovation to solve problems for small ship monitoring and management. This article through to the tianjin port small vessel monitoring system the research process, put forward a set of small boat monitoring system based on GPS technology. |
