Abstract: For the traditional large-scale aquaculture farms,  fish abnormal behavior was according to farmers′ subjective experiences, and monitoring water quality just by smelling water smell, etc., which led to monitoring at random, with high monitoring error rate, wasting time and energy.  So this paper designed a quality management system based on ZigBee wireless network. This system took Texas instruments CC2530 chip as core and built a wireless sensor network, which could collect data such as temperature, dissolved oxygen content, pH, nitrite concentration and turbidity of the monitoring points in real time, and transfered them to PC. At the same time, according to the water quality situation and through SMT32F101 controller, PC could control oxygen pumps, valves, bait casting machine and other equipments, and timely deal with the water quality abnormal situation. Experiment indicated that the water quality data transmission rate could reach 140 kb, and effective transmission distance was over 150 m. This system possessed strong expansibility, low power consumption, high stability, etc. characteristics. It could also satisfy the functional requirements of water quality monitoring, add oxygenation, timing bait casting, disease prevention and control, etc..

摘要： 传统大型水产养殖场凭养殖户的经验，通过观察水体颜色、鱼类异常行为以及闻水味的方式监测水质，导致监测随意性大、出错几率高、费时费力，因此设计了基于ZigBee无线网络的水质管理系统，该系统以德州仪器CC2530芯片为核心构建了一个无线传感网络，该网络可实时采集监测点温度、溶解氧含量、pH、亚硝酸盐浓度、浊度等数据，并传送到PC上位机。PC上位机同时依据水质情况，通过SMT32F101控制器控制供氧泵，水阀、投饵机等设备，及时对水质异常等状况进行及时处理。试验表明，水质数据的传输速率可达到140 kb，有效传输距离在150 m以上，系统具有可扩展性强、功耗低、稳定性高等特点，能够满足水质监控、增氧、定时投饵、病害防治方面的功能要求。
