The Design And Realization Of Intelligent Traffic Signal Switching System

ITS(INTELLIGENT TRANSPORTATION SYSTEMS) is a very important part of morden city,with ITS there are many questions about signal switching ,for example it is necessary to set some camera,and it is necessary to control them,such as the zoom,the focus and the pan of the camera.on the same time ,it need to work with the signal of the camera.some time it also needs to work with the signal on the monitor of computers.such applications are all about the technology of signal switching.so i choose signal switching as my project.My project is about how to overcome the questions on signal switching system,the questions i want to overcome on the project are: 1,how to design the whole model project in the way of software engine.2,how to overcome the question about the communiation on the serial port.3 how to design the parements of application and how to read them.on the question 1, I design the whole model on different object,such as projector,videomatrix VGAmatrix .on the question 2,1 design serial port class in multithread application it is smart and effective.on the question 3 ,the project uses XML technology to overcome the problem of parements.In the end there are the source code about my project,it is useful.
