the method for sending the corresponding instruction according to the broken yarn or unbroken yarn signal comprises the following steps: the PLC receives a yarn breakage signal sent by the single spindle detection sensor;
the PLC controller commands the corresponding broken-end spindle electromagnetic induction valve to be completely opened, and outputs a joint signal through a man-machine intelligent interface so as to inform a driver of joint processing;
the PLC receives the yarn-breaking-free signal sent by the single spindle detection sensor;
the PLC controls the corresponding valve of the spindle electromagnetic induction valve to be closed by three fourths;
and the control module is used for adjusting the working frequency of the frequency converter of the cotton suction fan and controlling the opening and closing of the electromagnetic induction valve according to the instruction sent by the processing module.
4. A network side server, comprising:
at least one processor; the method comprises the steps of,
a memory communicatively coupled to the at least one processor; wherein,
the memory stores instructions executable by the at least one processor to enable the at least one processor to perform the spun yarn breakage cotton suction automatic control method according to any one of claims 1 to 2.
5. A computer-readable storage medium storing a computer program, wherein the computer program, when executed by a processor, implements the spun yarn breakage cotton suction automatic control method according to any one of claims 1 to 2.
