Research On Water Quality Monitoring System For Aquaculture Based On The Beidou Communication Module

In order to solve the communication problems in aquaculture areas without base stations or mobile phone network coverage,this paper puts forward the monitoring system based on the Beidou module for monitoring the water quality parameters of the aquaculture waters in real time through the satellite communication system to ensure the economic benefits of aquaculture and the quality of aquatic products.The main research contents of this paper are as follows:This thesis clarifies the technical characteristics of the required communication technology based on the system requirements analysis,studies the importance of water quality parameters such as turbidity,temperature and dissolved oxygen,and proposes a design plan for the aquaculture monitoring system.Using the communication function of the Beidou communication positioning module to complete the data communication work of the monitoring system.For the aquaculture monitoring terminal,the hardware circuit design of the monitoring terminal is completed by Altium Designer10.A data communication control system is designed based on a 32-bit micro-processing chip(STM32F103)and Beidou communication module I(FB3511).Analyzed the function of the Beidou communication module,developed the communication coding and decoding program according to the Beidou satellite communication protocol,and the data acquisition and processing program is written by C.The PC management software based on Win Form is developed by C# to analyze short messages,send instructions and store data.Through the host computer software,serial communication between Beidou communication module II(FB3511)and the host computer,the host computer realizes the real-time monitoring of the aquaculture water quality,and realizes data sharing through the data visualization platform Sugar.Authorized users only need to use Smartphones,tablets,and other devices to be connected to the Internet to view monitoring data.In addition,a numerical prediction model based on BP neural network algorithm was established on the monitoring information management platform by applying C# and neural network function library.Relevant experiments were carried out in the laboratory in order to verify the effectiveness of the aquaculture monitoring system based on the Beidou communication module.The results show that the aquaculture monitoring system uses the Beidou communication module to realize real-time monitoring of terminal nodes;water quality parameters can be displayed on the upper computer software interface.Through the visualization platform Sugar,authorized users can share data and information.
