基于STM32单片机的泥沙含量监测仪的设计

Design of Sediment Content Monitor Based on STM32 Microcontroller

本文设计了一种可以自动测量河水中泥沙含量的监测仪。该监测仪以STM32F103VBT6单片机为控制核心,采用鸭嘴式水位传感器、压力传感器作为模拟量采集模块。可以实现自动实时监测河水泥沙含量,测量精度±5%,提高泥沙测验精度,减轻测验人员的劳动强度,缩短监测时间,提高泥沙监测的精度以及自动化水平。同时该监测仪还可以在长时间无操作时自动断电,减少能量消耗,实现节能。

An automatic monitoring instrument for measuring sediment content in river water is designed.The monitor uses STM32F103VBT6 single chip microcomputer as the control core,and uses duck bill water level sensor and pressure sensor as the analog acquisition module.The monitor can automatically monitor river sediment content in real time with an accuracy of±5%.This instrument improves the accuracy of sediment testing,reduces the labor intensity of testing personnel,shortens the monitoring time,improves the accuracy of sediment monitoring and the level of automation.At the same time,the monitor can also automatically power off when there is no operation for a long time,reducing energy consumption and saving energy.
