摘　　要：针对船舶串口接口的电子设备数据共享问题,提出了1种技术方案。利用配对的虚拟串口和自行开发的串口转发软件,将1个物理串口的数据转发到多个虚拟串口上去,应用软件可以继续利用串口模式,实现数据的读取,方便了新软件系统的开发,也避免了更改已有的软件系统,便于船舶计算机多软件系统的集成和协同,更好地发挥各自的优势,提升船舶的运营水平。Many maritime electronic devices output data through their serial interfaces and usually more than one on-board PC software programs need such data .However ,the unique access characteristic of each device prevents directing share access from a single serial interface .This paper presents a software solution to this type of problem .The solution is to use pairs of virtual serial ports and an in-house software to forward the data from a physical serial to multiple virtual se -rial ports .With the proposed method ,all application software can access serial data and avoid changing the existing soft -ware ,which will facilitate the integration of computer systems on-board and enhance the operation of the ships .
