Abstract本发明涉及一种基于霍尔元件的无刷直流电机测速装置及其控制方法,包括:霍尔信号处理单元接收无刷直流电机的霍尔元件输入的霍尔信号进行滤波整形后输出至单片机处理单元;单片机处理单元对霍尔信号处理单元输入的信号进行核心算法处理后通过对外接口单元输出速度信息;对外接口单元具有5V和3.3V逻辑电平对外输出串行接口;方法包括:进行设备初始化;当有串口中断请求时,执行串口中断服务程序;当有定时器请求时执行定时器中断服务程序;如有结束命令则结束循环控制过程。本发明将利用霍尔元件测速的功能提炼出来,专门的测速模块,对外通过串口传递信息,便于系统的集成,较好的解决了测速波动的问题,具备故障报告机制,通用性较好。
Other AbstractThe invention relates to a brushless direct current motor speed detector based on a hall element and control method thereof. The brushless direct current motor speed detector based on the hall element is characterized by comprising a hall signal processing unit, a single chip micyoco processing unit and an external interface unit, wherein the hall signal processing unit receives a hall signal input by the hall element of the brushless direct current motor and output the hall signal subjected to filter shaping to the single chip micyoco processing unit the single chip micyoco processing unit outputs speed information through the external interface unit after core algorithm processing is carried out on the signal input by the hall signal processing unit and the external interface unit is provided with a 5 V logic level external output serial interface and a 3.3V logic level external output serial interface. The control method of the brushless direct current motor speed detector based on the hall element comprises: carrying out device initialization executing a serial port interrupt service routine when a serial port interruption request exists executing a timer interrupt serviceroutine when a timer request exists and finishing a loop control process if a finish order exists. According to the invention, a special velocity measurement module is designed by utilizing the velocity measurement function of the hall element, and information is transmitted to the outside through a serial port, which is convenient for the systemic integration and the problem of velocity measurement fluctuation is solved preferably, a trouble report mechanism is provided, and the universality is better.
