Design And Research Of Continuous Barrier System Of Electronic Road Test In Automobile Driving

The electronic automatic road test device has been gradually popularization indomestic automobile driving road test at present, that is, the traffic invigilation officerssupervise the students test process, and give the achievement of the examinee red-handed,This examination method is not only waste manpower and financial power, but also dopingman-made subjective factors during the examination, and it can’t meet the growingdemand of the examinee quantity. The electronic road test methods is monitoring theexamination process by electronic machinery and equipment.and judging test scores bythe computer, and embodies fully the objective, justice and fairness.The continuous barrier assessment is a important index in the automobile driving roadtest system. The paper is mainly studies the continuous barrier system testing inautomobile driving road test. and write the vehicle test software to the continuous barrierassessment by the software of visual C++, when the automobile rolling or rubbedcontinuous barrier device, the sensor which install in the continuous barrier detects signals,and send to the receivers by the wireless network, meanwhile through the real-timeshooting and transmission, the computer can display the driving conditions in the controlcenter.In order to test the vehicle software, to develop the simulation software to thecontinuous barrier detection, through the serial communication, the vehicle software andthe simulation software can do real-time communication, and the various sensor signalswhich is the venues signals transfer to the vehicle software. Simulating the variouspossessed condition. Including the automobile traveling track, each disk-shaped state, forexample collision, rolling the disk-shape and rolling line and so on.After the vehiclesoftware simulate the whole examination, the vehicle software can evaluate the assessableresults, and display the possessed projects and qualified or not. Through the wirelessnetwork send to the control center, display the results on the screen.
