Data Acquisition Subsystem Of Monitoring System In Ocean Environment Based On WSN

At present people for the environment, the attentions of the result of industrialization gradually improve the unceasing development, people for environmental pollution has increasingly heavier. Marine disasters rates are also increased year by year, caused to the life of people with different degrees of threat.Marine areas for the Marine environment, extensive monitoring requires a lot of manpower and material resources in monitoring, there are many not convenient. Wireless sensor network solved this problem, because of its inherent particularity; absolutely it in vast areas of environmental monitoring is occupational considerable advantage. Wireless sensor network is that it another bit of environmental requirements are low, can be in bad weather normal work, won't appear as ever as limited network interruption, cause data line not normal transmission.For Marine this special geographical environment, node in distribution can be allocated at the bottom of the sea, or distribution in Marine middle. At the bottom of the sea, as long as the situation is more easily placed on the need to monitor the node location can. Therefore, we through the way of nodes use buoy, and will give ships floating driving bring a lot of inconvenience. So we put the buoy tied node, fixed point, through line length to control node position, so that they could monitor for a particular position. The data acquisition module for the whole monitoring system is a very important place. This system is in the Linux operating system, the system of the safety performance is higher, and have good open for the development of work put forward is convenient. Develop language adopted Java, it relative to other languages more flexible, don't object oriented more direct.
