| 摘 要： | 为了能够驱动聚合物分散液晶材料(PDLC)对光产生电控现象,设计了基于MINI2440的驱动电源及信号采集系统。波形信号先经功率放大模块放大,再给升压模块提升电压,以达到PDLC需要的400V内可调的驱动电压要求。系统可提供给PDLC正弦波、方波以及三角波。最终实现经过PDLC材料后,输出信号在LCD触摸屏上显示和输出信号数据采集。系统可高效满足PDLC所需的对波形、电压、频率、相位的调节。 |

| Abstract: | In order to drive polymer dispersed liquid crystal (PDLC) material to produce electricity to light the phenomenon of control, power supply and signal acquisition system were designed based on the MINI2440. The waveform signal was amplified by the power amplifier module, and the voltage was improved to achieve the required PDLC driving voltage of 400 V adjustable within the requirements by the voltage booster module. System can provide the PDLC sine wave, square and triangle waves. Ultimately through the PDLC material, the output signal on the LCD touch screen display and output signal data were acquired. This system can efficiently meet the voltage, the waveform, the frequency, the phase adjustment which PDLC needs. |
