【摘要】：在铝电解工业中,铝电解槽运行状况检测的重要性不言而喻,然而,随着铝电解工业的不断发展,以往的检测手段已不能满足现代工业控制系统的需求。为此,本文设计了以TI公司的TMS320VC5416为核心处理器,以铝电解槽阳极系列电流与槽电压为监测对象的铝电解槽监测系统。本文主要就硬件设计与软件开发两部分对系统进行了详细的说明。系统的硬件设计部分主要论述了系统的硬件整体设计方案,就50路模拟信号(1路槽电压信号,24路阳极铝导杆等距压降信号,24路阳极铝导杆温度电压信号以及1路槽电压备选信号)的信号特点对系统进行了芯片选型与整体架构的设计。系统硬件架构包括DSP5416最小系统模块、多路模拟选择控制模块、A/D模块、FLASH模块、数码管显示模块、实现与上位机PC通信的USB模块以及电源模块。系统的软件开发部分主要就下位机DSP系统软件开发与上位机人机界面的设计两部分做了较为详细的说明。最终,下位机系统实现了精度达1.2mV的50路模拟电压信号的采集,并基于性价比较高的USB芯片CH372,实现了下位机DSP采集系统与上位机PC的数据通信,通过上位机基于VC++6.0开发的友好的人机界面实现了对监测数据的显示。
[Abstract]:In the aluminum electrolysis industry , the importance of the health detection of aluminum electrolysis cells is self - evident . However , with the development of the aluminum electrolysis industry , the past detection methods have been unable to meet the demand of modern industrial control systems . To this end , the paper designs a monitoring system of aluminum electrolysis cells with the anode series current and the cell voltage of the aluminum electrolysis cell as the monitoring object . This paper describes the hardware design and software development in detail . The hardware design of the system mainly discusses the hardware design of the system . The hardware architecture of the system includes DSP 5416 minimum system module , multi - channel analog selection control module , A / D module , FLASH module , digital tube display module , USB module for communication with PC PC and power module . Finally , a 50 - way analog voltage signal with the accuracy of 1.2mV is acquired by the lower computer system , and the data communication between the DSP acquisition system and the upper computer PC is realized based on the USB chip CH372 with high cost performance , and the display of the monitoring data is realized through the friendly man - machine interface developed by the upper computer based on VC ++ 6.0 .
