一种小型双路水下电视驱动系统设计
针对核电站广泛应用的双路水下电视驱动系统存在体积大且重等不足，设计并实现了一种小型10路直流电机驱动系统，完成双路水下电视的所有动作驱动。驱动系统以C8051F340单片机为核心，通过USB模块接收上位机控制指令包。根据解码指令，系统利用SPI编程2块集成功率驱动芯片DRV8823实现6路电机驱动，通过PWM驱动2片DRV8412实现4路电机驱动。试验结果表明，该电机驱动系统可同时实现10路直流电机的有效驱动，应用于双路水下电视具有可靠性高、体积小和发热少等特点。...

The drive system selects C8051F340 as its core controller, and receives the instruction package of the host through the USB module. According to the decoding instruction, the SPI interface is adopted to program two DRV8823 to achieve the drive of 6 motors, and the PWM signal is outputted to drive two DRV8412 to achieve the drive of 4 motors.
