[Abstract]:The research content of this paper is derived from the research project "Research on the technology of shortwave frequency selection and chain building system". This paper will proceed from the demand of the scheme of shortwave frequency selection and chain building system. The basic software module and single board test scheme of shortwave communication control board are designed and implemented. The main work and achievements of the author are as follows: 1) the short wave frequency selection and chain building system is mainly by the user terminal. The shortwave communication control board is responsible for running the link building protocol in order to ensure the normal operation of the communication chain building protocol. According to the basic module design scheme, the following software modules of communication control board are designed and implemented: serial interface module, Ethernet module. System time module, general timer module, communication module with DAC chip, watchdog module, forbidden JTAG module. Shortwave communication control board is used as the communication controller of shortwave frequency selection and chain building system. The interface is used to communicate with the user terminal, and the serial port is used to exchange data with Modem, Beidou module and transceiver. In the system of communication control board, the timer module is run. In order to keep the synchronization of communication both sides, the hibernating RTC module is used to provide the timing function for the state jump of the building chain communication protocol. And through hibernating RTC module in the control board to run with the world standard time synchronization system time, out of the system security and stability considerations. The disabling JTAG function module and watchdog module are implemented. These function modules are essential to ensure the normal operation of the system protocol and control software. The single board test scheme of communication control board is designed and implemented. After the welding of communication control board is completed. In order to check whether the single board can work normally, the test software of PC user and the single board test program of communication control board are written. The serial port, Ethernet port and system time on the single board are realized. After the basic module is integrated into the whole control board program, the test proves that each functional module can work normally and can meet the performance requirements of the system. At the same time. The veneer test of the welded control board also shows that the veneer test meets the design requirements.
