[Abstract]:As the oldest radio communication, shortwave communication has the advantages of simple communication equipment, flexible networking, low cost, and its medium is ionosphere, so shortwave communication is not easy to be destroyed by man-made, so shortwave communication is in the field of communication. Especially in the field of military communications has an irreplaceable position. The research content of this paper comes from the research topic of short-wave frequency selection and chain-building technology. This paper mainly designs and implements a new type of shortwave communication system, which can quickly and reliably carry out adaptive frequency selection and automatic link establishment. The system consists of three parts: user terminal, communication controller and channel machine. This paper designs and implements the system software, which runs on the user terminal, including the frequency selection module and human-computer interaction. The main research results are as follows: (1) the short-wave frequency selection and chain-building system is briefly analyzed. Firstly, the hardware composition of the system is analyzed, including the main functions of each component and the workflow of the system. Then, the software architecture is analyzed and its functions in the application layer, link layer and physical layer are given. (2) in the system, the user terminal controls the communication controller through the network port to complete the corresponding communication services. This paper analyzes and designs the network interface between the user terminal and the communication controller, designs a set of network interface rules, and gives the frame format of sending, receiving and processing data between the user terminal and the communication controller. It includes data frame and interface command frame. (3) according to the working principle and functional requirement of short wave frequency selection and link building system, the user terminal software of the system is designed and implemented. Firstly, the design scheme and work flow of each module of the system are analyzed, including initialization module, frequency selection module, chain building module, data transmission module and data storage and analysis module, which include the system initialization module, frequency selection module, link building module, data transmission module and data storage and analysis module. It focuses on the design of frequency selection module and its software realization, including point-to-point frequency selection and point-to-point frequency selection. Then, based on the analysis and research, the user terminal software of the system is designed, and the corresponding functions are completed. Finally, the human-computer interface of the software is designed, and its design idea is briefly analyzed. The interface is complete and intuitive, and the operation is simple. (4) in this system, The function of automatic link establishment and data transmission is completed by the user terminal software control communication controller, so it is necessary to test and verify the link building and data transmission function of the communication controller. At the end of this paper, some testing programs in user terminal software are designed and implemented by using multi-thread technology, including blind connection service, LQA service, chain-building service test scheme and its test flow.
