D, motion interpolation computing module (404) are according to speed command signal, and system's interpolation cycle of appointment, and position and the speed parameter that unreels motor and winding motor in each sampling period calculated in interpolation, and it is passed in the position control module (405);
E, position control module (405) are obtained the instruction in motion interpolation computing module (404) each sampling period on the one hand, the code device signal of real-time sampling motor self on the other hand, by the control algolithm of self, calculate each cycle motor and move due speed, it is sent in the motor drive module (406) as command signal;
F, motor drive module (406) produce the motor-driven command signal, realize the control of motor speed, thereby finish the Tension Control to winding apparatus;
Some position switchs of G, winding apparatus feed back in general purpose I/O interface module (408) in real time, soft PLC module (409) manages and realizes logic control to it, simultaneously the data input/output module (402) of switching information by the upper strata is delivered in the external data base, and goes up its state of demonstration at display device (106).
10. the constant-tension control method of the described Industrial Coil winding apparatus of claim 9 is characterized in that:
Control algolithm in the step e is a pid control algorithm; Described winding apparatus drive control signal comprises the D/A switch signal of 16 bit serial DAC chips, and this drive signal provides high speed analog quantity motor speed control signal for system.
