基于GPRS的无刷直流电机控制系统设计

Remote Control System of BLDC Motor Based On Wireless Technology

设计开发了基于无线通信的远程控制系统,无线通信采用的是GPRS技术。GPRS模块的MC53i和DSPTMS320F2812进行双向通信,而DSPTMS320F2812产生PWM波形和开关量信号控制直流电机L298N最终实现对无刷直流电机的转速控制(PWM)和正反控制(开关量信号)。

This paper designs and develops a remote control system based on wireless communication tecnnology.ln tlqis system, use GPRS as a wireless technology,the GPRS module MC35i builds up a bidirectional communication connection with the DSPTMS320F2812.Furthermore,the DSPTMS320F2812 generates PWM and switching signals to control the BLDC mentor driver L298N,and finally control the speed of the BLDC motor by the duty cycle of PWM waveform and the rotation direction by the seitching signals.
