Research On ZigBee-based Remote Monitoring System For Catfish Culture

Catfish is one of the most popular aquatic products in North China in recent years.The requirements of water environment such as temperature,dissolved oxygen,acidity and alkalinity,conductivity are high.How to ensure the quality of catfish culture by information technology and create economic benefits for farmers is an urgent problem to be solved.With the development of Internet of Things technology,it is possible to save human and material resources for Aquaculture Environmental monitoring.The design and implementation of Zig Bee-based catfish farming remote monitoring system has important practical significance and practical value.The main research work of this paper is as follows:(1)The characteristics and growth environment requirements of goby were elaborated,and the requirements of remote monitoring system for goby culture were analyzed.Four factors affecting the growth of goby were determined: water temperature,dissolved oxygen content,water acidity and alkalinity,and conductivity.(2)The hardware system of the remote monitoring system for catfish culture has been built.The monitoring node module is designed,and all kinds of sensors involved are analyzed and selected,including temperature sensor,dissolved oxygen sensor,acidity and alkalinity sensor and conductivity sensor.The microprocessor module of remote monitoring node,power module of monitoring node,router,coordinator hardware and gateway are designed.(3)Software design of remote monitoring system for catfish culture.IAR SYSTEMS development platform is selected to construct the software system based on Z-Stack development architecture,and information acquisition program is designed,including sensor node software,coordinator node software and gateway node software program.On this basis,information transmission mode is designed,including data standard format settings and data analysis.(3)In order to facilitate the application system to read and process data information,the necessary format conversion is carried out.According to the Internet standard protocol,the data format suitable for the information transmission of this system is designed.The data contains information header,project code,error-proof bits and other ancillary information.The measurement information contains the unique identification code of the sensor,the identification code of the network subnet and other information.(4)Finally,the application program of the host computer is developed,and the main function modules are realized.After the system is put into operation,all kinds of water quality parameters are detected and transmitted by sensors in real time.All real-time monitoring data are transmitted from sensors to coordinators.When the data exceeds the safety value,alarm signals are sent out by AT command,and finally displayed in the monitoring center to realize the fine management of long-distance catfish breeding environment.The results show that the system can replace the manual mode,give the monitoring data accurately,have the function of prompting and alarming,and achieve satisfactory results.
