A Satellite Ground Station Monitoring And Task Management Information System

With the rapid development of satellite communication technology in the field of civil communications and military communications,satellite data receiving stations are also being expanded in size,complexity and automation.Satellite data receiving station to undertake satellite data reception,processing and satellite data reception tasks management,data product information management.As the demand for automation of satellite data receiving stations continues to increase,the demand for monitoring and task management as a control center for satellite data receiving stations has also become more complicated.Especially for the deep-space exploration satellites,which have relatively slow development and more stringent safety and reliability requirements,the monitoring and task management technologies of data receiving stations are even more important.This thesis describes in detail the design and implementation of a ground station monitoring and task management information system.The system takes the requirement of a ground satellite data receiving station as a background,uses J2 EE as a development platform,and adopts a multi-layer C / S and B / S architecture.We first went deep into the satellite ground station,fully communicated with the ground station staff to understand the requirement,conducted an in-depth analysis of the requirement,extracted the main work flow,decomposed the requirement and communicated with the staff on many times to complete the requirements analysis.The satellite ground station only has an operator role,and the operator intervenes only in the event of a system failure,the execution of the task most of the time is fully automatic.The main function of the system is reflected in the automatic process and data conversion and migration,so we use business flow and data flow diagrams to describe the requirement.The monitoring and task management information system is divided into five parts: task management,system monitoring,data picture infomation processing and display,data transmission,data management service.Task management and system monitoring are most important functions of the system.Therefore,the descriptions of the system will focus on task management and system monitoring.In the fourth chapter,the overall system design,different dimensions elaborated,and in the form of sequence diagram to further describe the module functions.In the fifth chapter,use flow charts to describe the main work flows,use E-R diagrams and table structure to describe the main database tables,use system screenshot and program code to describe the system implementation.At the same time,test situation is described.The end of the thesis summarizes to the full text,proposes the research conclusion.
