Vehicle Monitoring System, Protocol Analysis And Study Of Construction Techniques,

Vehicle monitoring system is designed to achieve the purpose of getting the real-time information of user's vehicle and controlling the vehicle far away. This system has been used widely. It hasn't a long history, so the software structure isn't good enough. In this case, the system function can not be extended friendly. Data Server Center (DSC) is the core of the system and it needs a structure that can easily be extended for more function. Data Information Protocol (DIP) is the medium for the information exchanged between vehicles and DSC, and it has a changeable structure. So DSC needs a better method to deal with the DIP.The main work of this article is improving the strategy of DIP-parsing and DIP-building. And the purpose is that while a new DIP added, the software structure hasn't to be changed. The coring method of system designing is Driver-Design with XML, it means that the changeable DIP is not appeared in software code but on the XML document. And the XML document decides the code's running. So the first thing is designing DIP which must contain all the information and has a good structure and is reconfigurable. The second, Up on the method of Denver-Design with XML we must design a key word collection and the frame of the XML document. Then with the frame we change DIP into XML document. Finally, with the knowledge of software-refactoring and design patterns designing a better soft structure is necessary. After those work we can get some advantage. When the users need new function and a new DIP is needed, we only have to design a XML document to realize the DIP and the software is not need to make any change or only a little. And it is good for system's stabilization and the system can be reused.
