摘　　要：LNG加注是LNG燃料水上供应链中的关键环节,也是推动LNG作为船用燃料必须首先解决的问题;而LNG加注船加注控制逻辑较复杂,安全性要求高,传统的软件开发方法人工编写代码工作量大,且容易出错。基于此,提出一种快速的自动生成嵌入式软件代码的开发方法。首先在Simulink/Stateflow中构建基于有限状态机模型的仿真系统,然后利用Embedded Coder工具箱由模型自动生成C语言代码,再根据LNG加注船项目进行二次开发整合,最终生成优化的加注控制程序软件。经仿真验证,证明了该方法的可行性,在保证软件质量的同时,大大缩短了软件的开发周期。Bunkering is an important part of LNG-fuel supplying on water.It is also the first problem must be solved in promoting the usage of LNG as the fuel for ships.The control logic for LNG ship-to-ship bunkering is complex,and the safety requirement is high.It is a huge job to write the control software manually,and it is not unusual to make mistakes.In view of this problem a method of automatic programming of the control software is put forward.A simulation system based on finitestate machine is built in Simulink/Stateflow.The C language code based on the simulation system is produced automatically by using the Embedded Coder toolbox.The further development integrates the embedded code with the control system.The feasibility of this method is proved by simulation.This method ensures the quality of the code,in the same time,greatly shortens the software development cycle.
