Single-spindle monitoring control system based on PLC

The invention relates to a single-spindle monitoring control system based on a PLC. The system comprises a single-spindle magnetic detection sensor, the PLC and a human-computer interface, wherein thesingle-spindle magnetic detection sensor is arranged on a ring rail and used for detecting magnetic rings on a single-spindle steel wire ring in real time and collecting data during operation of spindles; the PLC is connected with the single-spindle magnetic detection sensor through a communication line and used for receiving the collected data sent by the single-spindle magnetic detection sensorand classifying, sorting, calculating and analyzing the collected data, the spindle speed, the broken end state and the broken end number of each spindle, whether weak twisting happens and joint timeare accurately detected, and meanwhile, the processed data is stored and sorted; the human-computer interface is connected with the PLC through a communication line and used for receiving the processing data sent by the PLC an
