| 摘 要： | 给出了基于GSM/GPRS的直流电机远程控制系统的设计方案。在该方案中,C8051F330单片机产生PWM波形和开关量信号控制直流电机驱动模块L298N最终实现对直流电机的转速控制(由PWM的占空比决定)和正反转控制(由开关量信号决定),同时C8051F330单片机与GPRS模块MC55之间通过串口实现双向通信,因此,MC55在收到用户从远端发送来的"命令"(即短消息)后就可以通过C8051F330单片机最终实现对直流电机的控制。

| Abstract: | An approach to remote control of DC motor is suggested based on GSM/GPRS.In this method,a C8051F330 MCU generates PWM and switching signals to control a DC motor driver L298N connecting with a DC motor,and finally control the speed of the DC motor by the duty cycle of PWM waveform and the rotation direction by the switching signals,respectively.Furthermore,the C8051F330 MCU builds up a bidirectional communication connection with a GPRS module MC55 by a series port.Therefore,MC55 can first receive remote commands（i.e.,short message concerning the switching signals and the duty cycle of PWM waveform） and then control the DC motor by the C8051F330 MCU. |
