| Abstract: | The characteristics of highway sensing devices that currently used were analyzed, existing road network sensor devices were classified and the common faults of highway sensing devices were summarized. Then the fault diagnosis methods of sensing devices were analyzed, including the fault diagnosis method which depends / doesn＇t depend on model. After that, the overall framework of portable diagnostic equipment was designed, and its hardware platform based on ARM9 processor and software platform under Windows CE were analyzed and compared according to the requirement of the actual situation. |
