[Abstract]:The passenger ship carries a lot of personnel, once the maritime disaster, will cause huge property losses and a large number of casualties, so the passenger ship evacuation calculation is an extremely important part of the ship design. The traditional evacuation calculation is carried out manually, the calculation process is extremely complex and tedious, and the efficiency is very low. However, the software specially used for passenger ship evacuation calculation is not perfect. AutoCAD is the main design tool of the ship design institute. Its universal function can not meet the needs of evacuation calculation. Using the secondary development technology of CAD to develop the assistant tool of evacuation calculation can not only improve the efficiency of evacuation calculation, but also avoid human negligence. It is a kind of research with less investment, quick effect and strong pertinence. According to the requirement of ship design institute to make the calculation document of passenger ship evacuation, the principle of evacuation calculation is fully analyzed and the secondary development technology of CAD is studied. According to the "Guide for the evacuation Analysis of New passenger ship and existing passenger ship" issued by the International Maritime Organization (International MaritimeOrganization) (), combined with the design process of evacuation calculation book, the auxiliary tool of passenger ship evacuation calculation based on AutoCAD is developed by using VLISP development tool and ActiveX technology. The complicated procedure of passenger ship evacuation calculation is greatly simplified, and the efficiency and accuracy of making evacuation calculation document are greatly improved. The main work of this paper includes: (1) studying the principle of passenger ship evacuation calculation and the "Guide" issued by IMO, analyzing its application on passenger ship, combining with actual work flow, dividing the process of making evacuation calculation into different design stages; (2) based on the analysis of AutoCAD software, the characteristics, general form, basic process, development model and development tools of CAD secondary development are studied. The framework model of the system is established, and the functional requirements of the system are analyzed. (4) using VLISP development tools and ActiveX technology, the functions of data collation module, evacuation calculation module and result output module are programmed, respectively. Design according to different function modules and create friendly man-machine interface. After the development of the tool is completed, it is applied to the calculation of the actual ship evacuation of the 2300 passenger ro / ro passenger ship, and good results are obtained, and the approval of the classification society is passed, which proves that the tool developed in this paper has very strong practical application value.
