Method, system and equipment for testing pulse frequency of stepping motor

Abstract

The invention provides a stepping motor pulse frequency test method, system and equipment thereof. The method comprises the steps that initial pulse frequency lower than starting pulse frequency, a frequency rising cycle and pulse frequency rising amplitude are preset; the initial pulse frequency is outputted to a stepping motor, and working audio data of the stepping motor are acquired simultaneously; the outputted pulse frequency is adjusted according to the frequency rising cycle and the pulse frequency rising amplitude; and the starting pulse frequency, resonance pulse frequency and the highest pulse frequency of the stepping motor are acquired according to the working audio data. Test intellectualization is realized and artificial intervention and judgment are reduced; besides, test efficiency and test precision and accuracy are substantially enhanced; furthermore, the stepping motor is enabled to work within the optimal pulse frequency range and great working state of the equipment can be guaranteed.

Description

technical field [0001] The invention relates to the field of stepping motor control, in particular to a method, system and equipment for testing the pulse frequency of a stepping motor. Background technique [0002] Stepping motors are widely used in thermal printing cores of POS machines, and play a very important role in thermal printing cores, which determine the printing effect and reliability of thermal printing cores; while stepping motors work in The pulse frequency of the motor plays a decisive role in the working state of the motor. It is necessary to make the stepping motor work in a suitable pulse frequency range as much as possible to ensure that the stepping motor maintains a good working state. [0003] The patent document with the application number 201120506493.8 discloses a mobile phone motor vibration test device. When the mobile phone motor vibrates, the microphone is used to collect the sound generated by the whole machine when the mobile phone vibrates, ...

Problems solved by technology

The above test method has a lot to do with the judgment of the tester, and the test efficiency is very low; especially the resonant pulse frequency of the stepping motor, it is often easy to miss the resonant frequency area during the test, and when the stepping motor works at the resonant pulse frequency , the motor cannot work normally, which will cause printing compression and printing stepping in the thermal printer core.
