基于智能传感网和模糊PID的水产养殖监控系统

鉴于目前国内水产养殖现代化监控系统的实际应用需求,提出一种基于CC2430和模糊PID控制策略的水产养殖环境监控系统。该系统采用CC2430为核心开发无线传感器节点,通过带有高精度温湿度传感器的数据采集终端采集环境数据,完成养殖环境中的溶解氧、温度、pH值等参数实时监测,各节点间通信遵循ZigBee协议,采用ZigBee技术实现无线传感器网络自组网和监控数据自动汇聚,应用模糊PID控制算法对偏差进行处理,实现参数的精确调节,采用嵌入式数据库管理模式实现终端节点和数据管理及预警等功能。试验结果表明该系统的实用性和高效性,解决了养殖池内的复杂布线问题,适于环境参数的自动监测,可推广应用。

Environmental Information Monitoring System of Aquiculture Based on Intelligent Sensor Network and Fuzzy-PID

A kind of aquiculture environmental factors monitoring system based on CC2430 and fuzzy-PID was designed aiming at the actuality that aquiculture monitoring system was exactly need modern technology in our country.The system used CC2430 as the core to develop wireless sensor nodes which follow the ZigBee communication protocol,used the data collection terminal with high-precision sensor to collect data of the environment,such as temperature,dissolved oxygen and pH,used ZigBee technology to achieve networking of wireless sensors and the automatic aquiculture of monitoring data,and used the fuzzy PID control algorithm to improve the accuracy of test data.The management function of various sensor nodes and a large number of environmental data was achieved based on embedded database.Experimental result indicates that the system is stable,high reliable in data transmission and easy to use,and can be widely used in various areas of automatic monitoring of environmental parameters.So it is suitable for application.
