摘要
为解决鱼塘管理系统测量误差大、评估失准等问题,设计了鱼塘多节点水质评估系统,该系统利用遥控手柄控制气动船体运动,利用GPS/BDS双模定位模块对所监测水域进行空间与时间上的准确定位和时间同步,利用水质传感器获取鱼塘的酸碱度、水温及浑浊度,利用模糊分析法对鱼苗生存适宜度进行综合评估,利用WIFI、GPRS、GSM 3种可切换的通讯方式将获取的信息发送至App。测试结果表明,测量相对误差在3%以内,可实现对鱼苗的生存适宜度的综合性评估。
For solving the fish pond management system's problems such as large measurement error and inaccurate assessment,a multi-node water quality assessment system for fish ponds was designed. A remote control handle was used to control the movement of the pneumatic hull. GPS/BDS dual mode positioning module was used to get the position and time of monitored water area. Water quality sensors were used to get the pH,temperature and turbidity of fish ponds. Fuzzy analysis was used to comprehensively evaluate the survival of fish. WIFI,GPRS,GSM were used to send messages to App switchable. The test results show that the relative error is within 3% and a comprehensive evaluation of the survival of fry can be achieved.
