英文摘要	The 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.
