As the DY winding machine operates in step S1, the detector 100 that detects a change in the coil detects the change in the coil.

The change in the coil sensed by the sensing unit 100 in step S2 is measured by each measuring instrument 102 and analog data is output from the measuring instrument 102.

The analog data output from each measuring instrument 102 is input to the analog / digital converting unit 106 through a unique channel of each measuring instrument 102 and converted into digital data.

The digital data output from the analog / digital converter 106 is input to the CPU 108, and the digital data is displayed on the display 110 through a unique channel of each instrument 102.

In step S3, the CPU 108 determines whether a permission signal for storing digitally converted BCD data from the PLC 114 has been output.

If it is determined that the permission signal is output from the PLC 114 as a result of the permission signal presence / absence (YES), the flow proceeds to step S4.

In step S5, the individual tension data of the channel 3 is changed analog / digital and input to the CPU 108, and the CPU 108 displays the individual tension data on the display 110.

In step S6, the CPU 108 determines whether a permission signal for storing the individual tension data has been input from the PLC 114, and proceeds to the next channel if there is no permission signal. Data is transferred to the PLC and stored.

In step S7, the upper winding amount data of the channel 4 is inputted to the CPU 108 by analog / digital change, and the CPU 108 displays the upper winding amount data on the display 110.

In step S8, the CPU 108 determines whether a permission signal for storing the upper winding amount data is input from the PLC 114, and proceeds to the next channel if there is no permission signal. The upper wound lifting amount data is transmitted to the PLC 114 and stored.

In step S9, the shaping pusher amount data of the channel 5 is inputted to the CPU 108 by analog / digital change, and the CPU 108 displays the shaping pusher amount data on the display unit 110.

In step S10, the CPU 108 determines whether the permission signal for storing the molding pusher amount data is input from the PLC 114, and proceeds to the next channel if there is no permission signal. The molding pusher lifting data is transmitted to the PLC 114 and stored.

In step S11, the coil length data of the channel 6 is changed to analog / digital input to the CPU 108, and the CPU 108 displays the wire length data on the display 110.

In step S12, the CPU 108 determines whether a permission signal for storing the coil length data has been input from the PLC 114, and returns to channel 1 if there is no permission signal. The coil length data of the transmitter is transmitted to the PLC 114, stored, and returned to the channel 1.

As described above, according to the present invention, an analog signal output from each measuring instrument is converted into a digital signal and stored therein, so that the database can be converted into a digital signal, and the present invention can be used for both a current output measuring instrument and a voltage output measuring instrument. By digitalizing the data of each instrument and storing them in PLC, there is no economical advantage because there is no increase in the input contact point of PLC according to the increase of the instrument, and the network configuration of each facility is possible by automatically collecting data of each instrument. There is this.
