The Theoretical Model Of The Configuration Software, Based On The Monitoring Of Embedded Systems

With the development of computer science and technologies, configuration software has been greatly used in the industrial control system and is speedily developing. The primary reason is that it can simplify complicated control system and heavy program, and reduce working hours. Many configuration software mainly apply in common computer and IPC (Industrial Personal Computer), but not in embedded control system.We designed such embedded configuration control system conformed to the international standard IEC611131-3, which chiefly apply in the fields of industrial equipment, lab, smart home system, etc. It integrated the logical control function imitating PLC and the animate picture monitoring function. Due to conform to the new standard, using Object Modeling Technique (OMT) and using C＋＋, the MMI (Man Machine Interface) and the Real-time Data Base System (RTDBS) were integrated together. So the configuration software is good universal and open.The paper discusses the structure of the configuration control system and its hardware and software platform. Then, the paper emphasize how to build the model of MMI, the model of RTDBS, the model of I/O system and the work strategy system, and then give the detailed plan.Firstly, using OMT, we build the object model, the dynamic model and the function model of the MMI and give the detailed plan. Thus the MMI is good expansibility and has a great of pictures, and can make rapidly the control interface. The user can save the picture made by him and reuse the picture in the future.Secondly, we build the RTDBS by using Object Oriented Database Technique and give the plan of save data. We solve the problem by way of using different language in application program and RTDBS, and perfectly integrate the application program and the RTDBS.Lastly, the paper gives the detailed plans of I/O system, control strategy and script compilation units. The model of I/O include device driver, the scheduler of driver, the tool of setting device driver, the file of setting. Without setting the device driver in the embedded system, user can download the application program, which is made by the configuration soft, and can directly run the program.The work of this paper is the part of a whole project, but it is the base of achieving more advanced functions.
