Abstract

The invention discloses a stepping motor array control system and a control method thereof. The stepping motor array control system comprises a host machine, a controller, a complex programmable logic device (CPLD) driving device, an H-bridge driving chip and a stepping motor array which are connected with one another, wherein the stepping motor array comprises a plurality of stepping motors. The stepping motor array control system can accurately record running information of the stepping motors at the last time and guarantee that the stepping motors run precisely according to a control instruction during switching; the CPLD driving device is used for expanding the number of accessed stepping motors, a switching relay is avoided, and the cost of the whole system is reduced; furthermore, a phenomenon of short circuit caused by synchronously starting of an upper bridge and a lower bridge of a driving circuit can be avoided; and the CPLD driving device is used for finishing logic switching and controlling a plurality of paths of stepping motors to work at different times or at the same time. The stepping motor array control system also has the advantages of low cost, convenience in operation and the like.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a stepping motor array control system and a control method thereof. Background technique [0002] With the rapid development of microelectronics technology, power electronics technology, automatic control technology and material science, many new stepper motors with superior performance have appeared at home and abroad. This type of stepping motor combined with computer control technology is widely used in various optical path adjustments, transportation, household appliances, electrical transmission and weaponry, medical equipment and other fields. [0003] The use of the stepper motor needs to cooperate with the controller, and the ordinary AC and DC power supply cannot be used directly. Generally, one controller can control one motor or synchronously control the operation of several stepper motors. In practical applications, it is often necessary to control two or ...
