[0029] like Fig. 9 As shown, a control method of the optical fiber winding system with adjustable tension and precise wiring arrangement includes the following steps: Step 1: 1.1. Pass the optical fiber reel through the transmission shaft of the long-axis servo motor customized for the precision tension control pay-off unit and move it to the corresponding optical fiber pay-off clamping reel, and lock the other end with a locking sleeve; 1.2. Pass the exposed end of the optical fiber through the wire guide wheel and tension guide wheel on the same side in sequence, then through the wire hole on the same side of the rotating disk, and finally through the wire guide wheel of the wire arranging unit, and fix the optical fiber on the wrapped cable; Step 2: 2.1.

When the main power unit is started and the equipment is powered on, the PLC control module sends a voltage adjustment electrical signal to the main motor inverter. The main inverter sends the real-time output frequency to the main power motor. The main power motor rotates to drive the main power pulley to rotate, and the main transmission pulley is driven to rotate through the main synchronous belt, thereby realizing the rotation of the rotating hollow spindle. At the same time, the encoder power wheel fixed on the rotating hollow spindle drives the encoder transmission power wheel through the encoder synchronous belt, thereby driving the pulse encoder to rotate, and feeding back the real-time rotation speed electrical signal to the PLC in real time, thereby realizing real-time monitoring and closed-loop control of the twisting speed. 2.3. The precision tension control pay-off unit is started. After the equipment is powered on, the PLC control module sends a voltage adjustment electrical signal to the pay-off servo controller. The pay-off servo controller outputs voltage to the long-axis servo motor in real time. The long-axis servo motor drives the optical fiber reel to realize the rotation pay-off action. Through the feedback of the real-time pay-off tension electrical signal of the tension sensor, the closed-loop control of the pay-off tension is realized. 2.4. The precision wire arrangement unit is started. After the equipment is powered on, the PLC control module sends a voltage adjustment electrical signal to the wire arrangement servo controller. The wire arrangement servo controller outputs voltage to the micro servo motor in real time. The rotation of the micro wire arrangement motor drives the track screw of the precision wire arrangement unit to rotate, driving the wire arrangement slider to move in a straight line. The wire arrangement slider drives the wire arrangement bracket to move in a straight line. The wire arrangement bracket drives the wire arrangement guide wheel to move in a straight line. When the wire arrangement slider moves to the stroke sensor 1, the stroke sensor 1 sends the commutation electrical signal to the wire arrangement servo controller. The wire arrangement servo controller outputs a commutation voltage to the micro servo motor. The micro servo motor rotates in the opposite direction, driving the wire arrangement slider to move in a straight line in the opposite direction, and then drives the wire arrangement guide wheel to move in a straight line in the opposite direction. Similarly, when the wire arrangement slider moves in the opposite direction to the stroke sensor 2, the stroke sensor 2 sends the commutation electrical signal to the wire arrangement servo controller.

The micro servo motor rotates forward, driving the wire arrangement slider to move in a forward straight line, and then drives the wire arrangement guide wheel to move in a forward straight line, thereby realizing the forward and reverse reciprocating wire arrangement function at a controllable speed.

[0030] The main control principle of this system is: after the equipment is powered on, the pay-off tension, twisting speed and winding pitch are set on the industrial control panel, and the industrial control panel transmits the set pay-off tension electrical signal, winding speed electrical signal and winding pitch electrical signal to the PLC control module. At the same time, the tension sensor and pulse encoder send the real-time pay-off tension electrical signal and real-time rotation speed electrical signal to the PLC control module, and the PLC control module sends the real-time pay-off tension electrical signal and real-time rotation speed electrical signal to the industrial control panel, which can realize closed-loop monitoring of real-time parameter feedback. The PLC control module receives the set pay-off tension electrical signal, set twisting speed electrical signal, After setting the twisting pitch electrical signal, the real-time pay-off tension electrical signal and the real-time rotation speed electrical signal, through internal calculation and comparison, ① the PLC control module sends a voltage adjustment electrical signal to the pay-off servo controller, and the pay-off servo controller outputs voltage to the long-axis servo motor in real time. At the same time, the long-axis servo motor will feedback a real-time rotation pulse signal to the servo controller to achieve precise closed-loop control. The main control idea is that when the real-time pay-off tension is lower than the set pay-off tension, the output voltage of the pay-off servo controller is reduced to reduce the speed of the long-axis servo motor. When the real-time pay-off tension is higher than the set pay-off tension, the output voltage of the pay-off servo controller is reduced. The output voltage increases the speed of the long-axis servo motor, thereby realizing the precise control of the wire tension of this system; ② The PLC control module sends a voltage adjustment electrical signal to the main motor inverter, and the main inverter sends the real-time output frequency to the main power motor. At the same time, the PLC internally checks the set twisting speed and the real-time rotation speed fed back by the rotary pulse encoder in real time. The main idea is that when the set twisting speed is lower than the real-time rotation speed, the PLC reduces the speed of the main motor by reducing the output frequency of the main inverter. When the set winding speed is higher than the real-time rotation speed, the PLC increases the speed of the main motor by increasing the output frequency of the main inverter. Thereby, the precise control of the winding speed of this system is realized; ③ The PLC control module sends a voltage adjustment electrical signal to the wire traversing servo controller (to control the wire traversing speed), and the wire traversing servo controller outputs voltage to the micro servo motor in real time. At the same time, the micro servo motor will feedback a real-time rotation pulse signal to the servo controller to realize precise closed-loop control. At the same time, the stroke sensor 1 and the stroke sensor 2 send a commutation electrical signal to the wire traversing servo in real time, and the wire traversing servo controller outputs a commutation voltage to the micro servo motor to realize the commutation of the micro servo motor. This process does not change the speed control instruction given by the PLC control module, but only adds a commutation action.

[0031] Further improvement, after the PLC control module simultaneously receives the set pay-off tension electrical signal, the set twisting speed electrical signal, the set twisting pitch electrical signal, the real-time pay-off tension electrical signal and the real-time rotation speed electrical signal, through internal calculation and comparison, ① the PLC control module sends a voltage adjustment electrical signal to the pay-off servo controller, and the pay-off servo controller outputs voltage to the long-axis servo motor in real time. At the same time, the long-axis servo motor will feedback a real-time rotation pulse signal to the servo controller to achieve precise closed-loop control. The main control idea is that when the real-time pay-off tension is lower than the set pay-off tension, the output voltage of the pay-off servo controller is reduced to reduce the speed of the long-axis servo motor; (Specifically: PLC controls the servo controller through the voltage adjustment electrical signal (actually an analog electrical signal), (the analog electrical signal is a voltage signal, and the servo controller will reduce the output voltage and the long-axis motor will reduce the speed when the analog voltage is reduced)).

[0032] When the real-time pay-off tension is higher than the set pay-off tension, the output voltage of the pay-off servo controller is reduced to increase the speed of the long-axis servo motor (specifically: PLC controls the frequency converter through voltage adjustment electrical signals (actually analog electrical signals), (analog electrical signals are voltage signals, and when the analog voltage is reduced, the frequency converter will reduce the output frequency and reduce the speed of the main motor; when the analog electrical signal voltage is increased, the frequency converter will increase the output frequency and increase the speed of the main motor)), thereby achieving precise control of the pay-off tension of this system; ②The PLC control module sends a voltage adjustment electrical signal to the main motor inverter, and the main inverter sends the real-time output frequency to the main power motor. At the same time, the PLC internally checks the set twisting speed and the real-time rotation speed fed back by the rotary pulse encoder in real time. The main idea is that when the set winding speed is lower than the real-time rotation speed, the PLC reduces the speed of the main motor by reducing the output frequency of the main inverter. When the set winding speed is higher than the real-time rotation speed, the PLC increases the speed of the main motor by increasing the output frequency of the main inverter. (Specifically, the PLC controls the inverter through the voltage adjustment electrical signal (actually an analog electrical signal). (The analog electrical signal is a voltage signal. When the analog electrical signal voltage is increased, the inverter will increase the output frequency of the inverter and increase the speed of the main motor)), thereby realizing the precise control of the twisting speed of this system.

[0033] To sum up, through the above improvements, the present invention solves the problem of optical fiber winding for sensor arrays and realizes fiber winding without joints; it also solves the problem that conventional equipment is mainly external twisted body twisting equipment, which is mostly passive and has no tension control, and cannot meet the tension requirements of optical fiber winding, and the winding equipment with tension control cannot achieve precise wiring.
