[Abstract]:Autonomous navigation based on X-ray pulsar is a new autonomous navigation technology for spacecraft. By detecting X-ray pulse of deep space pulsar, precise position calculation is carried out to realize autonomous navigation and operation management of spacecraft with high precision. Due to the blocking of the Earth's atmosphere, it is difficult to observe the X-ray pulsar signal on the ground, so the X-ray pulsar navigation flight test needs to be carried out on the research carrier flying outside the atmosphere, but the space-borne test is costly. The ground simulation system for X-ray pulsar navigation is established because of its wide range and difficulty. Because the system involves a large number of data transmission problems in the process of ground simulation research, in order to improve the efficiency of the research work and make full use of the latest development technology, the relevant data can be collected conveniently and the remote wireless transmission can be carried out in time. Real-time sharing and processing has become a problem to be solved. In this paper, the research of remote data acquisition system based on Android is based on the cooperative project of X-ray pulsar navigation ground simulation system of Xi'an Institute of Optical Precision Machinery, Chinese Academy of Sciences. The whole ground simulation system of X-ray pulsar navigation includes: X-ray signal generator, vacuum system, MCP detector, front-end shaping and amplifying circuit, time measurement circuit and remote pulse profile data acquisition and transmission control system. The remote acquisition and transmission control system of pulse contour data is the focus of this paper. With the rapid development of modern industry and information technology, as well as the popularization of mobile communication network and wireless LAN technology, mobile devices, especially Android mobile devices, play a more and more important role in people's production and life. In this paper, a design scheme of remote data acquisition system is presented. Firstly, the data acquisition and remote control system of high precision time counter based on FPGA is designed. Then Ubunt 14.04 LTS operating system is installed under VMware Workstation virtual machine, and Hadoop pseudo-distributed environment is built. Then the data processed by MATLAB is stored in HDFS, the pulse contour data in HDFS is loaded into the relational database MySQL with Sqoop, and the Java Web program is programmed to connect to the MySQL database through JSP technology, and then the Web application is deployed on the Tomcat server. It realizes the functions of user registration, login, accessing data and so on. Finally, it uses Java language to develop Android application program under the Eclipse development environment, and uses SQLite as the database of Android registered users. Realization of Android mobile remote access to X-ray pulsar pulse profile data. Based on Android system combined with FPGA technology, Hadoop cloud platform technology, JSP technology and database technology, the data acquisition and control system of PC is established, and the remote data acquisition of Android mobile terminal is realized. This system can realize a variety of data acquisition, various transmission networks and collection terminals, and explore the feasibility of the application of Android system in remote data acquisition system.
