Abstract

The invention relates to a motor driver based on a ZYNQ dual-core processor and belongs to the technical field of circuit control. The motor driver comprises a DC motor control chip, a DC motor, a ZYNQ dual-core processor, a photocoupler and a MOSFET driving circuit. The ZYNQ dual-core processor calculates collected motor task state information and control instruction information to obtain a PWM control signal. The optocoupler isolates the PWM control signal to generate an isolated signal and outputs the isolated signal to the DC motor control chip. The DC motor control chip receives the isolated signal, then generates a signal for driving a MOSFET circuit and outputs the signal to the MOSFET driving circuit to control the on and off of a MOSFET tube. The MOSFET driving circuit receives the signal for controlling the on and off of the MOSFET tube and driving the MOSFET circuit and drives the DC motor to rotor by the on and off of the MOSFET driving circuit. The motor driver is based onthe ZYNQ dual-core processor, the number of processors and system size are reduced, and the hardware design is simplified.

Description

technical field [0001] The invention relates to the technical field of circuit control, in particular to a motor driver based on a ZYNQ dual-core processor. Background technique [0002] Most of the current DC motor driver processors use single-core processors (such as DSP, ARM, etc.) in the control mode. One processor implements the control algorithm, and the other processor is used to give instructions and collect status information. The two processors are distributed on two chips, and information exchange is performed between the processors by way of digital bus or analog quantity transmission. The number of processors is large, the system volume is large, the hardware design is complex, and there is electromagnetic interference and influence of electrical signals during communication. Contents of the invention [0003] In view of the above analysis, the present invention aims to provide a ZYNQ dual-core processor-based motor driver to solve all or part of the above-me...
