为了解决电动阀门在沙漠等环境下的供电问题，提出了一种利用光伏电池充电的蓄电池为电动阀门供电的新方法。采用数字信号处理器（DSP）构建了数字软件锁相环（DSPLL）控制电路，该电路由直流电机控制的脉宽调制（PWM）驱动。实验证明，光伏电池可以提供足够的能量来开启或关闭电动阀。该控制方法不仅实现了整个系统的功能，而且运行更加精确可靠。此外，该方法大大降低了供电系统的谐波和纹波，使整个系统实现了在线远程控制、数据采集和传输，并能在LCD上精确显示电机的转矩。同时，直流电动机能够更精确、稳定地控制电动阀的流量大小。
In order to address the issue of power supply for electrical valve in the deserts and other circumstances, a novel method of electrical valve power supply by accumulator is presented, which is charged by photovoltaic cell. The controlling circuits of digital software phase-locked loop (DSPLL) using digital signal process (DSP) is constructed, which is driven by the pulse-width modulation (PWM) controlled by DC motor. The experiments prove that the photovoltaic cell can provide enough energy to turn on or shut down the electrical valve. The control method not only realizes the functions of the whole system, but also runs more precisely and reliable. In addition, this method greatly decreases the harmonics and ripples of power supply systems, making the entire system realize online remote control, data acquisition and transmission, and display the torque of electrical machine on LCD precisely. At the same time, the DC motor is able to control the flow magnitude of electrical valve more precisely and steadily.
