Design And Implementation Of Monitoring System For Anti-interference ADS-B Receiver

ADS-B(Automatic Dependent Surveillance-Broadcast)technology has the characteristics of high positioning accuracy,fast update rate and low maintenance cost.It has been widely promoted and applied in the United States,Australia,Canada,China and other countries,and is the main surveillance in the future aviation field.The rapid promotion of ADS-B has greatly promoted the development of its receiving equipment.However,most of the ADS-B receiving equipment developed in and abroad do not have anti-interference function.Therefore,a realtime monitoring system based on ADS-B anti-interference receiver is designed,which has great practical significance for engineering applications.Firstly,the overall functional requirements of the ADS-B anti-interference receiver are analyzed,and on this basis,the architecture of the system is designed in detail.The functional modules of the embedded system and monitoring software are given respectively.Secondly,an embedded message processing system based on ARM processor is designed,which mainly includes the design of ADS-B message parsing module and message generation module.At the same time,the process of message verification and decoding in the parsing module is introduced,and the message generation module is analyzed.The generation and transmission process of ADS-B data exchange report and ground station status report are given.Then,the core design and implementation methods of the software part of the monitoring system are studied,including the design of monitoring the received data,the design of monitoring the receiver operating state and the design of controlling the receiver.The monitoring of the received data is realized by monitoring the track data.Therefore,a humancomputer interaction interface is designed.The monitoring and control of the receiver can be realized through various functional modules on the operation interface.Finally,the function of the monitoring system is used to analyze the receiving data and receiver performance,and a test platform is built to test each function of the system one by one.Results show that the monitoring system can complete the monitoring and control functions of the anti-interference receiver,providing important reference for the development of related monitoring equipment.
