海洋牧场多参数智能监测系统设计与实现

摘要

Aiming at characteristics of South China Sea aquaculture industry,a multi-parameter intelligent monitoring system for marine pasture is proposed.Temperature,pH and turbidity are selected as monitoring objects.A single-chip microcomputer is used to collect sensor data underwater,and the data is sent out by low frequency signal transmitting module.In order to achieve long-distance data transmission,ZigBee technique is used for automatic networking above the sea.The LabVIEW graphical programming is used to achieve real-time monitoring for marine ecological parameters by upper PC and provide remote accessing function.Field tests show that this system has the characteristics of good flexibility,low power consumption,low cost and so on.It can be well used in marine ranching to monitor water quality and upgrade management level of marine ranching in surveillance and alarming.%针对南海水产养殖业特点,设计了一种海洋牧场多参数智能监测系统.选取温度、pH值和浊度作为监测对象,利用单片机收集水下传感器数据,通过低频信号发射模块传输数据,通过ZigBee技术自动组网实现水上数据远程传输,上位机利用LabVIEW图形化编程实现对海水生态参数的实时监测,并提供远程访问功能.外场测试证明:系统具有灵活性好、功耗低、成本低等特点,可以较好地用于海洋牧场水质监测,全面提升海洋牧场的科学化监管和告警等管理.
