Design And Application On Water Quality Data Collection And Remote Monitoring In Multi-sensors System

With adjustment of the structure of aquaculture,the scale of industrial aquaculture is expanding constantly which increases the impact of aquaculture water quality on aquatic products and economic benefits.As an essential factor of the modern aquaculture to achieve automation and intelligence,the remote monitor system is developing rapidly.But the aquaculture industry is a relaxed management system and has a bad mode of water environment monitoring.In this paper,in view of the aquaculture water environment as the research object,a water quality data collection and monitoring system based on the web and cloud computing was presented.The system realized the function of remote collection,storage and management of water quality parameters such as water temperature,dissolved oxygen,PH,water level,and the remote control of oxygen pump,Water pump was also realized.Hardware modules mainly contain information collection module,aquatic environment control module,wireless communication module ?Arduino board get the water quality parameters through the sensor.Then the collected data uploaded to the web server and cloud platform for real-time communications by the W5100 Ethernet network module.The software platform is composed of the internal control system based on local area network and the cloud platform which has the function of data storage and data analysis.Internal control system uses Final framework,MVC hierarchy,to achieve real-time monitoring of water quality parameter data and the implementation of the control of the equipment and other functions.The cloud platform is divided into two parts: AWS IOT and web services.Then through AWS IoT services to complete equipment authentication,access equipment and data receiving and distribution.Based on ASP.NET MVC framework of WEB service,realize the implementation of sensor equipment management,water quality data storage and visualization.This system of aquatic flat created a stable and suitable for the growth of living environment,can make aquaculture products have higher reproduction,growth rate and quality.Through various performance tests,the results show that the system data accuracy is high,the network packet loss rate is low,the system control execution module high success rate,it can well satisfy the needs of the monitoring and control.
