Research And Design Of Remote Monitoring System For Unmanned Rice Transplanter Based On Android Platform

The unmanned rice transplanter has effectively solved the problems in terms of high labor i ntensity,low work efficiency and poor transplanting quality,etc.The unmanned transplanter mo nitoring system that based on the Android platform can accurately monitor the working condition parameter and transplanting quality in real time.If the machine malfunctions,monitoring system would send alarm messages timely to the client-side.This function ensures the safe and efficient operation of unmanned rice transplanter,as well,facilitate a real-time understanding of the curre nt state for users.Meanwhile,it can reduce the security risks and improve work efficiency.The dissertation builds an unattended transplanter monitoring system based on the Android platform,which mainly includes the onboard PC end of the unmanned transplanter,the remote central data server and the Android monitoring client.When the unmanned rice transplanter's on-board PC collects and processes the data of the transplanter,it is transmitted to the remote monitoring server through the 4G wireless network;the remote central data server realizes the data transmission between the server and the on-board PC and the Android monitoring client through the network.Data processing,data storage and data management;Android client remote monitoring center displays the real-time data of the transplanter's operation status in the form of human-computer interaction interface,and combines the information of its planting quality and work area with the electronic map,and can perform abnormality Status alarm information and control instructions are issued to realize the management and control of the rice transplanter.Thesis mainly includes the following research contents:1)Analyzed the current research status of remote monitoring system and unmanned agricultural machinery based on Android platform.According to the functional requirements of unmanned transplanter monitoring system,the overall architecture based on Android platform system was designed,and the structure and principle of the system were introduced.Introduce the technologies involved in the system development process.2)Aiming at the situation that multiple unmanned transplanter cross-regional collaborative operations,the shortest path group control scheduling algorithm is proposed.The Dijkstra algorithm,Bellman-Ford algorithm and Floyd-Warshall algorithm are used to optimize the operation of the shortest path and achieve parallel computing.The shortest path algorithmsimulation calculations are performed on different computer hardware configurations,and the analysis results of the shortest path algorithm are given to provide guarantees for the group control and scheduling of multiple unmanned rice transplanters in a cooperative and efficient operation.3)Explain the construction of the Android development environment,set up the Java environment,install Eclipse,Android SDK and ADT plug-in,analyze the requirements of the Android monitoring client based on this,and develop the Android mobile client according to its functional structure.The data of the server can be obtained to display the working condition data and the seedling planting quality information.Finally,the communication format of the server-side data package is designed to ensure the reliability of the communication between the Android monitoring client and the on-board PC of the rice transplanter.4)The hardware functional module of the unmanned rice transplanter was tested.Based on the good testing conditions,the software module was used to analyze and test the various functions of the system.The test results show that the monitoring system can realize the real-time monitoring and management of the remote operation of rice transplanter.
