[Abstract]:Based on Beidou and radio integrated underwater acoustic buoy communication platform, this paper studies the design and implementation of its data transmission and control function. The data transmission function of this communication platform is realized by two parts: the remote part, which uses the satellite transmission mode inherent in Beidou navigation system, and the short-range part, which uses the radio network communication protocol TCP/IP to complete the data transmission. The hardware design uses the embedded microprocessor ARM as the main control processing unit and the ARM as the auxiliary expansion unit, and controls the Beidou communication unit and the network communication unit together with each other. The software design is based on the transplant of embedded Linux operating system, and then designs and debugs the driver and application program of the main control processing unit ARM, accomplishes the data transceiver and radio network communication of the "Beidou" / ARM dual-system module. The auxiliary extension unit (FPGA) mainly completes the control of the system logic function and the expansion of the interface, including the design of the ARM bus reading and writing timing, the synchronous pulse generation and the timing simulation of the FPGA, and the data cache. Logic control and power management functions, with the main control unit ARM to complete the platform communication task. In this paper, the background and significance of underwater acoustic buoy and its communication platform are discussed. The hardware design of the platform is based on the overall requirement of the system, then the selection of the core devices is established, and the overall scheme of the system hardware and the circuit design of each module are finally determined. The software design of the platform first explains the process of transplanting the embedded Linux system environment. Then the system function software is designed in two parts: ARM and FPGA. The workflow of each functional module is analyzed and the program is designed and debugged. The communication platform has been proved to be stable and reliable by laboratory and offshore experiments, and the data communication between the buoy communication platform and the ship display control platform can be completed in real time. The completion of the function of the platform meets the requirements of the established design. The expected design goal has been achieved.
