Based On Arm And Linux Traffic Survey Form To Record The Instrument Design

Traffic survey is a very important foundation work. The survey data is basis of the traffic planning, traffic analysis, road transport facilities design,road construction and operation ,traffic management and control, traffic safety and traffic flow theory. It is very important to improve the level of survey equipment and to lift the efficiency of traffic engineering. With the development of computer and network technology,the application of embedded system has been commonly used,more and more people like like the embedded products because of the cabinet,convenient and utility.Especially in the recent years,the embedded products have been commonly used in lots of areas,such as national defense,industrial control,telecommunication,official automation and digital consumption and so on.As a result,the embedded system designed with graphic user interface and easily used are with high applied ability and worth research.In order to change the traditional way of traffic survey by hand or mechanical, I design a portable transport survey recording instrument using modern electronic technology, computer technology. In order to be advantageous for input the data to the recording instrument,I use the touchscreen. Has developed based on the QT data form procedure, has compilated each module driver and the data upload procedure, preserves the recorded data in the computer by the Excel form's form.The paper first introduced the establishment of the embedded development environment, the translation and the transplant of the Boot Loader, the translation and the transplant of the essence, then has designed the hardware circuit, has developed the driver of each module , finally the design of form procedure, chinese input method development, the superior machine software's compilation and so on. Finally, I list some parts that need to improve in the system.I hope that the improvement of the system to make in the future.It will be more convenient.
