Embroidery thread tension control method of embroidery machine

The invention provides an embroidery thread tension control method of an embroidery machine. The invention discloses an embroidery thread tension control method for an embroidery machine. The method comprises the following steps: setting a threshold range m of tension control through a control module; reading an embroidery pattern and calculating the amount of embroidery threads of the current needle; controlling a thread feeding module to feed threads according to a matched thread feeding amount for embroidering according to the amount of the embroidery threads of the current needle; an embroidery thread tension value in the embroidery process is obtained in real time through a tension detection module; comparing the tension value of the embroidery thread with a set threshold range of tension control of the embroidery thread; if the embroidery thread tension value does not exceed the threshold range, repeating the step S4; if the embroidery thread tension value is higher or lower than the upper limit of the
