Abstract

The invention relates to a stepping motor electric control detection method and system. The stepping motor electric control detection method comprises the following steps of: acquiring a motor control instruction sent by an electric control mainboard; sending a step number signal to a stepping motor based on the motor control instruction, so that the stepping motor outputs a step number execution feedback signal after rotating a corresponding step number according to the step number signal; acquiring a step number execution feedback signal; and sending an electric control detection signal to an upper computer based on the step number execution feedback signal, so that the upper computer obtains an electric control detection result of the stepping motor according to the electric control detection signal. According to the stepping motor electric control detection method and system provided by the invention, a signal transmission closed loop can be formed, namely, an electric control detection loop is formed, so that the reliability of a judgment basis is effectively ensured, human errors are effectively avoided, and the accuracy and reliability of a detection result are ensured; and the automation degree of the detection process is improved, the detection efficiency is improved, and the labor and time cost is saved.

Description

technical field [0001] The present application relates to the field of motor control, in particular to a stepping motor electric control detection method and system. Background technique [0002] At present, with the development of science and technology, especially the development of permanent magnet materials, semiconductor technology, and computer technology, stepper motors have been widely used in many fields. For example, the opening and closing angle of the air-conditioning air deflector is determined by the rotation angle of the stepper motor controlled by the air-conditioning main board. The opening angle of the air deflector of the air conditioner's internal unit is directly related to the adjustment of indoor cooling and heating temperatures, and is an important link that affects the user's comfort. The comfort of air conditioning is improved. In the production process of air conditioners, it is necessary to test the electric control process of the air conditione...
