在主着陆场搜索态势系统中 ,车载系统与北京中心间的海事卫星通信数据链路的通断直接影响搜救的及时性和正确性 ,关系到各级指挥员对搜索态势的准确把握和及时决策。针对车载海事M站与卫星之间的数据链路因指挥车爬坡、转向容易引起中断的技术问题 ,利用通信线路载波检测技术 ,设计卫星通信数据链路的实时监测与自动拨号重建链路软件 ,确保了整个态势系统数据传输的实时、准确、可靠。
In the search system of the main landing site, the on-off of maritime satellite communication data links between the vehicle-mounted system and the Beijing center has a direct impact on the timeliness and correctness of the search and rescue, as well as the accurate grasp of the search situation and timely decision-making of commanders at all levels . Due to the fact that the data link between the M-M stations and satellites in the vehicle is steered by command cars, the technical problems that easily cause interruptions are that the communication line carrier detection technology is used to design the real-time monitoring and automatic dial-up reconstruction link software of the satellite communication data links , To ensure that the entire situation of the system data transmission in real time, accurate and reliable.
