| Abstract: |
| A type of portable data sampling and analysis equipment based on DSP(Digital Signal Processor)TMS320F206 and embedded operating system is designed.It can sample 16-channel analog signals and 8-channel binary signals at the same time.The data analysis module takes the embedded computer as its core and the decoding circuit and I/O circuit as its peripheral.The software consists of data sampling and data analysis procedures.Programmed with the assembly language TMS320C2XX,the data sampling procedure samples and uploads data of power system.Its flowchart is presented.The data analysis software is based on embedded Linux real-time operating system.Its main procedural interfaces and their functions are also provided.The designed equipment runs well. |
