Driving Simulator Data To Support The System

By the continuous and deep application of driving simulator ,it need more and more efficient organized data .First ,driving simulator must to deal with the static terrain data's saving and providing .Second ,by use it in traffic characteristic study the simulator need to deal with the dynamic scene data .In addition ,after the simulation experiment the simulator would produce some new data and information ,which can be used to analyses the experiment .Only make a good use of those new data and information can show the driving simulator's value ,so how to organize this new data is a problem of simulator at now . Last,the lot of object that studied by simulator are space entry relation ,especially in city traffic study .And that ,some theory of GIS have large power to treat the problem ,so let the simulator can deal with the space geography graphics data may be a way of develop simulator.All above problems are focus on data processing ,so it is demand to develop a module to processing data ,this paper just aims it .As we all know ,on data processing the database system have large advantage ,so this paper utilize database as data manage platform ,apply database theory ,build a database model struck , which is fit for the simulator's data characteristic , and then design a data exchange interface to exchange the data between simulator and database system .This paper combine with c ++ program language to processing and optimize the data ,adopt multithreading technology to provide extension data to memory by many times which reduce disadvantage of consume large memory in some extent . On providing data ,the system organize the scene data as some block dynamically , so the program can run by little calculator , provide terrain data in good time and meet to the demand of driving simulator .to record simulator's running parameter and simulation process the system use ADOX technology to create a database dynamically ,which can record simulator 's information in really time. In addition ,this paper have done some work for data format and data manage ,and then try to study the possibility of combine GIS with driving simulator, use MapX and VB achieved map data ,road traffic information and simulator's three-dimensional data band to geography graphics ,so those data can inquire and display by each other.The database of simulator, of course, is a large system project which connection many complexity substantiality such as human, vehicle, road, environment and so on. It was hard to find the inherent relation among this entry, so it needs more endeavor of latter for the database system of driving simulator to improve it. This paper just states some foundation work, just as the first step to attempt the database system of driving simulator.
