Aquaculture Aeration Intelligent Systems

Tianjin is located in the downstream of Haihe river, water enough, fishery and aquaculture rise, become one of the main tianjin agriculture industry, in Baodi, Tanggu and other regions have many large fish ponds. In recent years, Tianjin government take the detection and control of water quality environmental factor to fish ponds and intelligent automatic agricultural production seriously. The water environmental factors that affected the survival and growth of the fish include water temperature, dissolved oxygen, PH value, etc. And temperature is the major factor effect of static water aquaculture fish ponds in the growth.Nowadays, agriculture automation develop rapidly, agricultural production efficiency gradually improve. The fish ponds use a large number of agricultural automation facilities, such as sensors and aerators. Thus, the safety of fish ponds, power supplies, equipment maintenance are put forward higher request, the cost of production and business operation has been improved.This article through to the research of aquatic environment factor, Combined with ZigBee wireless communication network from chip CC2430for data transmission. The whole system is divided into the affiliate machine site, network part, main site three parts. The affiliate machine site used to collect data and control aerator stop; The network part choose ZigBee module is strong anti-interference ability, and the characteristic of module is AD hoc network function; The main site through the LabVIEW software write the user interaction interface in order to realize the preservation and the back to show of data, LabVIEW has the characteristics of fast development and program stability. The system realizes the fish ponds dissolved oxygen acquisition, automatic control, remote alarm and remote control function. Research results mainly includes the following respects:1.Do the research and analysis on the current dissolved oxygen sensing system for the fish ponds, master the sensor characteristics and amplification, filter regulate circuit.2.Using AVR chip collect sensor signal, and control aerator run and Stop. Carry out the distance interaction with user GSM module.3.Using ZigBee technology build networking, direct sequence spread spectrum technology prevent interference, and research the AD hoc network algorithm, make the network safe and reliable.4.Using LabVIEW2010in PC to release program for show the DO data and save to database. And we using LabVIEW to show the history and control the pump.
