摘　　要：描述了DSP控制实现的明渠非接触式流量计,对非接触式流量计的数据采集结构及通信接口电路组成做了详细讨论。介绍了在多数据量采集以及实时处理的要求下,将数据通过串行口传送到上位机实现远程监控。根据所提出的方案研制了一台基于TMS320LF2407A明渠污水流量计。The open channel flowmeter implementation based on digital signal processor TMS320LF2407A is described, and the detail data acquisition structure and communication interface circuit compositon is discussed. 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, an open channel flowmeter based on TMS320LF2407A is developed.
