Design Of Application Software In DSRC Composite Tester

ETC(Electronic Toll Collection)system is one of the most mature applications in intelligent transportation systems.With the Government's emphasis on the field of intelligent transportation,ETC system has been widely used and the number of users has also steadily increased.Safeguarding the equipment's performance and quality become an extremely important issue in the research and development and build process.Although there is a small amount of ETC monitoring equipment,but it can be only a passive listener,cannot quickly locate and solve the problem in time.This thesis is put forward and expanded on this basis-develop a DSRC Composite Tester which can analog the DSRC equipment,test the communications,analyze the ETC protocol.In this project,the primarily responsibility is to design the application software.The following is the main function of the application software.1.Achieve the air signal monitoring,and analysis of the signal.Save the baseband signal and trade information according to the trigger conditions.2.Simulate DSRC equipment to communicate with the target machine.Analyze the ETC transaction process and achieve the relevant parameter measurement.3.Realize the engineering test mode in order to measure and calibrate the parameters of the equipment.The most prominent feature of the system is having realized the DSRC devices emulation as well monitor the air signal.The compatibility of DSRC protocol has been realized by using mask table file creatively.It also cost savings for the secondary development.Propose a new algorithm to calculate the transmission frequency and the modulation of the signal according to the hardware features of the system.The application of this system will greatly reduce the cost of generating test,and promote the improvement of product quality.
