摘　　要：远洋船舶通信自动化控制过程中,易受到数据中频信号干扰的影响,导致控制效率较低。为此,提出基于北斗卫星通信技术的远洋船舶通信自动化控制系统。基于基本功能需求,选择手持终端机与时钟控制器型号,采用北斗卫星通信技术对基带信号进行降阶处理,以抑制数据中频信号扰动,并引入调制信号对通信数据进行捕捉,结合无线通信程序的设计,完成远洋船舶通信自动化控制。系统测试结果表明,在发送时钟频率范围为25~150 MHz时,所提系统的通信时延均在0.4 ms以下,能够有效提高通信控制效率。In the process of communication automation control of ocean-going ships,it is easy to be affected by data IF signal interference,which leads to low control efficiency.Therefore,the automatic control system of ocean-going vessels communication based on Beidou satellite communication technology is proposed.Based on the basic functional requirements,the model of handheld terminal and clock controller is selected,and Beidou satellite communication technology is used to reduce the order of baseband signal to suppress the data IF signal disturbance,and modulation signal is introduced to capture the communication data.Combined with the design of wireless communication program,the automatic control of ocean-going vessels communication is completed.The system test results show that the communication delay of the proposed system is less than 0.4 ms when the transmission clock frequency ranges from 25 to 150 MHz,which can effectively improve the communication control efficiency.
