Design And Implementation Of Environmental Factors Monitoring System For Aquaculture

With the constant improvement of the scale and breeding density of aquaculture and aquaculture water quality is getting worse, the demand for building environmental factors monitoring system for aquaculture is becoming more and more urgent. The traditional water quality monitoring system is based on manual operation and wire communication technology, which has man y shortcomings, such as high equipment cost, low reliability, poor data accuracy, wiring difficult, high maintenance costs. Therefore, the study of aquaculture environmental factors monitoring technology has high research significance and practical value.Aiming at the shortcomings of the traditional monitoring system, this subject puts forward a wireless sensor network environmental factors monitoring system which is based on the technology of Zig Bee. The system adopts upper and lower structure.The lower computer is composed of wireless sensor network(WSN), which transmits the water quality parameters by the wireless way and makes up for the deficiency of the cable way. PC monitoring system developed by using VB.The software has friendly interface,convenient opration complete function.In order for implementing the system automatic regulation and improving the stability and reliability of the system, chosing Fuzzy PID as the control algorithm and the output control the actuators, such as aerator, hot water pump, solenoid valve.System testing showed that the system is easy networking, high reliability of data transmission, reliable operation, low cost, which can accurately detect the change of environmental factors and control the system effectively.
