The Design Of Mangrove Wetland Monitoring System Based On ZigBee

Mangrove wetlands, which are important parts of the ecosystem along the tropical coasts, have significant ecological, social and economic values.In recent years, due to the influence of both mankind and nature, the areas of mangrove wetlands in China have keeping decreasing and the deterioration of ecological environment has become increasingly prominent. So we need to pay more attention to the conservation and rehabilitation of mangrove wetlands. In order to achieve the aim of protecting and monitoring the mangrove wetlands, this article designs a mangrove wetlands monitoring system, which is developed for the real-time measurement of various environmental parameters of mangrove wetlands.The research process is as follows.Firstly, in the view of the complexity of mangrove wetlands ecosystem environment, I design a wireless network combined static ZigBee network with dynamic ZigBee network. Static network consisting of ZigBee nodes in land areas is responsible for monitoring each sub region.The mobile node consisting of the unmanned ships with ZigBee nodes is used to monitor areas that researchers can not reach. The data information of mobile node is stored up waiting to join the land to join after the success of the network data transmission to the coordinator node and realize the data acquisition and transmission.In order to verify the feasibility and rationality of design scheme, the ZigBee nodes communication network performance testing.Secondly, in order to get the ecosystem environment parameter information and fluctuations of mangrove wetland,system will transform the physical or chemical signals into electrical signals which can identify by using the relevant sensor electrode.Through data acquisition and processing, the input to the single chip microcomputer measuring results can be achieved after the analog to digital conversion.In order to verify the validity and accuracy of the measured data, the relevant prior to measurement sensor electrode before the test of carring on the correction and the data acquisition function.Then, for the sake of getting the real-time display and storing the mangrove wetland ecological environment parameter information, the system can show measured area change trend of environmental parameters intuitively, we finished the design and development of the Lab VIEW PC monitoring center, at the same time, we have completed the test of real-time data and historical data storage function.Finally, after the system test, the whole monitoring network runs stably.Through PC monitoring center, we can get directly the environment parameter information of the measured area,such as light intensity, temperature, pH value, dissolved oxygen, conductivity and so on.Which can realize intelligent monitor to the mangrove wetlands.
