摘要
本文采用TI公司的DSP芯片TMS320LF2407A为控制核心,通过RS232接口控制液晶显示单元,完成绝缘耐压测试仪控制系统的信号调理、数据采集、处理、传输以及键盘、液晶显示、高压继电器控制等功能。该仪器具有定时精度高、操作简单、显示直观等特点。
The paper adapts the DSP chip TMS320LF2407A which is produced by TI Company as the control core, using RS232 interface to control the LCD unit. That finishes the insulated resistance and withstand voltage test instrument ’s the function of signal adjustment, data acquisition, process, transport and keyboard,LCD,high voltage relay control. The instrumemt is characters of high timing accuracy, simple operation, direct display and so on.
