| Abstract: | Describing the open channel flowmeter implementation based on digital signal processor TMS320LF2407A, discussing in detail data acquisition structure and communication interface circuit compositon. Under the demand for multi-data acquisition and real- time processing, adopting digital signal processor TMS320LF2407A to realize the scheme of sampling arithmetic. Accomplishing digital low pass wave filtering to sampling data with FIR algorithm, Realizing remote control through serial port and data is conveyed to upper level computer. According to the schemes,developing a open channel flowmeter based on TMS320LF2407A. |
