本设计是基于80C51单片机的步进电机控制系统，能够有效地对步进电机转速、方向的控制。为了能够更加人性化的控制系统，本设计还增加了语音提示部分，在实际应用当中由于紧急事件需要在短时间内了解电机的工作情况，这时看数码显示就很不方便，而语音提示提供很大帮助，只要按下语音提示按钮便能获取相关技术数据。 -The design is based on the 80C51 single-chip stepper motor control system, can effectively stepper motor speed and direction control. In order to be more user-friendly control system, the design has also increased the voice part in the practical application of these emergency needs due to a short period of time to understand the work of motor, when it is inconvenient to watch the digital display, and voice prompts to provide great help, as long as the voice prompts by pressing the button will be able to access to relevant technical data.
