| Abstract: | The hardware platform based on the high-speed digital signal processor chips,TMS320DM642,can be applied to the detection system for bridge cable surface damage,it is also capable of using CF card for data storage which has many advantages such as strong operational capabilities,low power loss and strong commonality,it fills up some deficiencies exist in the research methods both home and abroad.This paper firstly presents detailed structure and principle of the Compact Flash Card(CF card),and then propose a design scheme for the interface with DM642 and CF,establish a FAT file system based on CF card,which can enable the data storage on the format of file,therefore such operations as data access within Windows system can easily be done. |
