【摘要】 论文首先对国内外高速公路收费系统的现状作了分析,然后在分析UML建模技术的基础上,提出了基于UML的高速公路收费系统,系统采用多层C/S结构、MIDAS技术和Socket通讯,并介绍了车道软件实现的关键技术,即后台控制技术、时钟同步算法和实时性的串口打印技术,票据打印从8秒/张减少到3秒/张,效率提高了167%。更多还原

【Abstract】 This paper first analyzes the current situation of speedway charge system on aboard or internal,then puts forward a speedway charge system based on UML after analyzing the modeling technology with UML.The system adopts the multi-layer Client/Server structure,the technology of MIDAS and the communication of Socket.And introduces the key-point technology which is applied in the software of vehicle way.Such as the technology controlled by back-plat-form,the arithmetic of system clock synchronization in speedway charge fees system and the technology of a serial port printer in real-time.Reduces receipt printing’s time from8second/page to3second/page,raises efficiency to167%.更多还原
