Study. Wmbps System Software Design And Test Strategies

WMBPS system is used in steel tube's length measure, weight measure , color band, pin stamp and character stencil. Based on WMBPS system reconstruction in steel company,Tian Jiang. ,this paper bring forward a design method of software used in industry control. By use of a kind of flow chart, we can easily and clearly describe many complexed control system, this paper also probe into testing technique of industry control software, when hardware can't meet the need of test, we can refer to software simulate, the following is the main content of this dissertation.in chapter one , this dissertation introduce the WMBPS system reconstruction and explain the necessity of WMBPS system reconstruction.in chapter two, hardware components and it's respective theory in WMBPS system is introduced in detail , this chapter also make out the whole design of the software.in chapter three , A kind of flow chart which is called C-Based-SFC is introduced in detail, this kind of flow chart which combine C language with SFC flow chart is of great flexibility and usefulness and can be used in many complicated system. PLC software used in WMBPS system also adopt this kind of flow chart.in chapter four, supervising software in Industry PC is designed, software in PC is composed of three program, they are WINCC software, Control Software and Database software. By the way of pointing out the excellence and shortcoming of WINCC, this chapter explain why we select cooperation of multi-program, at last, the interaction of multi-program is also introduced.in chapter five, three testing program are designed . the first program called Share Memory monitor can be used to view and edit the data and the interface of WMBPS software. The second program which simulate the PLC program is useful in debugging WMBPS software, the third is useful in debugging PLC program, some debugging experience is also given in this chapter.in chapter six, some problem met in locale's debugging process and it's respective solution is introduced, the performance of the system when applied in practice is also in this chapter.in chapter seven, the work in this dissertation is summed up, this chapter point out the factor which lead to success of the WMBPS system reconstruction.
