Abstract

The invention discloses a control method for electromagnets in a machine head of a glove machine based on FPGA. The method comprises realization of a single-chip microcomputer control method and an FPGA control method. The method comprises the following steps: a single-chip microcomputer sends an electromagnet state signal through FSMC; additionally, FPGA uses an FSMC reception module to receive acontrol signal; a time-delay counter processes the signal; then, a circulating state machine continuously performs roll polling operation on the processed signal in order to produce an electromagnetcontrol output signal. With the method, complexity of a control algorithm for the electromagnets in the machine head of the glove machine. Real-time instantaneity is improved. The probability of burning out the electromagnets is lowered from the perspective of hardware design.

Description

technical field [0001] The invention belongs to the field of glove machines, in particular to a control method for a head electromagnet in a glove machine controller, in particular to an FPGA-based control method for an electromagnet at the head of a glove machine. Background technique [0002] In the current control strategy, most of them use single-chip microcomputer as the core to realize the control of the electromagnet of the glove machine head. And this kind of solution uses software to implement the control algorithm, and there are usually different types of electromagnets in the head of the glove machine, and the number is large. This will make the electromagnet control algorithm extremely complicated, and the glove machine controller includes other tasks such as controlling the motor. If the electromagnet control task is not completed within the specified time, it will cause the electromagnet to burn out. Contents of the invention [0003] Aiming at the deficienc...
