【摘要】 介绍了一种基于普通DSP的嵌入式视频图像采集与处理系统在混凝剂加注自动控制技术中的应用。该系统以TI公司C2000系列中的TMS320LF2812 DSP(数字信号处理器)芯片为核心,来实时采集和定量分析絮凝池中絮体的图像信息,算出絮体沉淀“等效直径”作为控制混凝剂加注率的目标值,并用进水流量和沉淀水浊度信号自动修正目标设定值。从而自动调整加注量,达到稳定沉淀水浊度的目的。更多还原

【Abstract】 This paper introduced the embedded video image capture and deal system based ordinary DSP,used as an auto-control technology of coagulant dosing.The core of the system is TMS320LF2812 DSP(digital signal process) of the TI Company.It can capture and analyze the image data.It also can calculate the equivalent diameter of flocculent particles that are used as the aim value of dosing.The water flux and deposition signal can auto-correct aim original value.So the system can auto-adjust the dosing,and then control the coagulant dosing well.更多还原
