The Design Of Water Quality Monitoring System In Aquaculture Based On Wireless Networks

With the constant advancement and update of electronic technology, theintelligentize aquaculture has become one focal point of current research. In China,the majority of aquaculture water quality monitoring use artificial manner, not onlythe data is not real-time, but also causing a waste of resources. It is difficult toachieve the expecting economic benefit. In order to meet the real-time andintelligence requirements, this article designs a set of water quality monitoringsystem in aquaculture to improve those existing problems in our country.Water quality monitoring system in aquaculture mainly consists of monitoringcenter, relay nodes, and data acquisition nodes. Data acquisition nodes utilize adistributed self-organizing network structure and they can detect temperature, PH,DOC, conductivity, turbidity and other water parameters.In order to facilitate systemexpansion, data acquisition node has a reserved interface.The relay node is used tothe build the delivery platform of the environmental parameters which can upload ordownload data and command, alarm for system anomalies. Monitoring center canrealize the data processing, storage and analysis via interpersonal interactioninterface. It is very convenient for user to remote monitor breeding waters. ZigBeewireless communication module and GPRS module are regarded as thecommunication medium among data acquisition node，relay node and monitoringcenter, in order to complete data transmission between nodes of water qualitymonitoring system in aquaculture. Use the algorithm of time synchronization tohibernateand wake up the whole network nodes, which can greatly reduce systempower consumption.Aquaculture water quality monitoring system can accomplish real-time datamonitoring and achieve the online transmission of water parameters in breedingwaters. Instead of manual operation, using network resources can save many humanresources and improve the intelligence level of aquaculture. Consequently, research on water quality monitoring system based on wireless networks has has importantpractical significance and broad application prospects.
