一种翻转式LED屏的供电控制系统
摘要：
本发明涉及一种翻转式LED屏的供电控制系统，包括：用于翻转式LED屏的视频播放配电系统。为了实现翻转式LED屏的视频播放与画面翻转同步，还包括：动力供电电路、翻转动力系统上的电机、切换电路、控制系统；控制系统与动力供电电路控制连接，使动力供电电路按控制系统的程序给翻转动力系统上的电机供电；这了便于维护保养，控制系统还通过切换电路来间接控制视频播放配电系统的交流接触器；上述技术方案可知，本发明一种翻转式LED屏的供电控制系统，不仅实现了翻转式LED屏的视频播放与画面翻转同步，而且具有结构简单、布线合理、稳定性高、便于维护、制造成本低的优势。
摘要（英）：

The invention relates to a power supply control system for a turnover LED screen. The power supply control system comprises a video playback power distribution system for the turnover LED screen. In order to achieve synchronization of video playback and picture turnover of the turnover LED screen, the power supply control system further comprises a power supply circuit, a motor on a turnover power system, a switching circuit and a control system, wherein the control system and the power supply circuit are in control connection; and the power supply circuit supplies electricity to the motor on the turnover power system according to a program of the control system, so that servicing and maintenance are facilitated; and the control system also indirectly contacts an alternating current contactor of the video playback power distribution system through the switching circuit. From the technical scheme, the synchronization of video playback and picture turnover of the turnover LED screen is achieved; and the power supply control system has the advantages of being simple in structure, reasonable in routing, high in stability, convenient to maintain and low in manufacturing cost.
