| 为解决现场评定废水在线自动监测系统中明渠流量计准确度的技术难题，设计了一套以高精度管道式流量计作为标准表的标准表法明渠流量计在线校准装置，研制了专用的现场流量信号采集测量系统，进行了硬件电路设计，并采用Qt开发了配套的上位机操作软件。通过大量不同条件下的现场对比试验，验证了系统的可靠性和装置的有效性，为准确实现废水流量在线监测提供了技术基础。 |
| 英文摘要: |
| In order to solve the technical problem of evaluating the accuracy of the open channel flowmeter in the on-line wastewater automatic monitoring system, a set of on-line calibration device of the open channel flowmeter with high-precision pipeline flowmeter as the standard meter is designed. A special on-site flow signal acquisition and measurement system is developed. The hardware circuit is designed, and the matching upper computer operation software is developed by QT. Through a large number of field comparative tests under different conditions, the reliability of the system and the effectiveness of the device are verified, providing a technical basis for the accurate online monitoring of wastewater flow. |
