Design Of Remote Monitoring System For Aquaculture Boat Based On Supermap GIS And Android Platform

Intelligentization and precision are inevitable trends in the development of modern agriculture,and remote monitoring technology is one of the important means to achieve agricultural intelligence.With the support of the Jiangsu Provincial Key Research and Development(Modern Agriculture)Project and the Jiangsu Natural Science Foundation Youth Fund Project,this article designed an aquaculture boat monitoring system based on the SuperMap GIS and Android platform.The system mainly includes remote monitoring server system,Android mobile client and aquaculture boat terminal.The shipboard terminal uploads the collected working condition parameters of the breeding boat and the plane position information relative to the dock to the remote monitoring server through the GPRS network;the remote monitoring server system realizes the data interaction between the server and the shipboard terminal and the Android mobile client through the network;Android mobile client can display the real-time working condition parameters of the breeding boat on the interface,and can track the breeding boat in real time in conjunction with the electronic map,and can send remote control commands and send alarm messages when the breeding boat has abnormal conditions.The thesis mainly includes the following research content:(1)Analyzed the domestic and international research status of unmanned operation boats and remote monitoring systems,designed the overall architecture of the system according to the functional requirements of the aquaculture boat monitoring system,and introduced the composition and principles of the remote monitoring system.Android system platform,GIS and TCP network communication technology involved in the development process are introduced.(2)In order to realize the automatic fine feeding of the breeding boat,a full coverage path planning method of the internal spiral traversal method of the breeding boat was designed,and a throwing performance test and a residual bait test were carried out.The positive calculation formula of Gauss-Kruger projection and the method of constructing pond plane working area and inner spiral full coverage path planning are introduced,and the correctness and practicability of the algorithm are verified from the perspective of experimental simulation and data analysis.Through the test to determine the relationship between the throwing amplitude of the feeding machine and the throwing plate motor voltage and the vibration motor voltage,the relationship between the feeding flow rate of the feeding machine and the vibration motor voltage,and the relationship between the weight of the feeding machine and the output voltage of the load cell to realize the functions of the boat's flow rate are measurable and controllable,the bait throwing rate is controllable and the remaining bait amount is measurable,and finally the refined bait feeding is realized.(3)Developed and designed the mobile client based on Android platform.Completed the construction of the Android development environment including the establishment of the Java development environment and the installation of Android Studio and Android SDK.Then,the demand analysis of the Android mobile client is carried out,and a mobile client with real-time display of working condition information and path tracking function is developed.Finally,the server-side custom data communication protocol is designed to realize the communication function between the server system and the Android mobile client and the breeding boat shipboard terminal.(4)Tested the main hardware function module of aquaculture boat.Under the premise of meeting the system requirements,combined with Android mobile client to carry out joint experiments on the system.The experimental results show that the system can monitor and control the fully automatic aquaculture boat in real time.
