[0038] Existing mechanical fiber stripping control circuits generally employ a combination of discrete stepper motors and independent drivers, requiring additional pulse generators, logic circuits, and multiple drivers, resulting in complex system structures and high hardware costs. Furthermore, traditional motor control relies on unidirectional PWM pulse signals, which cannot provide real-time feedback on motor status (such as stall or overheating), leading to asynchronous motor movements. This delay, especially during multi-motor coordinated motion, causes trajectory jitter, resulting in low fiber stripping accuracy in mechanical fiber stripping control circuits.
[0039] To address the aforementioned problems, this application proposes a fiber stripping control circuit.
[0040] Please see Figures 1 to 12 In one embodiment of this application, the fiber stripping control circuit includes a motor drive module 2, a first monitoring module 3, and a second monitoring module 4. The motor drive module 2 includes an adjustment circuit 21 and a drive motor 22. The adjustment circuit 21 is electrically connected to the drive motor 22, and the drive motor 22 is used to drive the optical fiber to rotate or the blade to move. The first monitoring module 3 is connected to the adjustment circuit 1 and is used to acquire the limit status signal of the drive motor 22. The second monitoring module 4 is electrically connected to the adjustment circuit 1 and is used to acquire the magnetic field change signal of the drive motor 22. The adjustment circuit 1 is used to adjust the output drive parameters of the adjustment circuit 21 according to the limit status signal of the first monitoring module 3 and / or the magnetic field signal of the second monitoring module 4.
[0041] By utilizing the adjustment circuit 21 and drive motor 22 in the motor drive module 2, the rotation of the optical fiber and the movement of the blade can be precisely controlled. Simultaneously, the first monitoring module 3 acquires the limit state of the drive motor 22, and the second monitoring module 4 monitors the magnetic field change signal of the drive motor 22, providing real-time feedback on the motor's operating status. This allows the adjustment circuit 1 to adjust the drive signal sent to the adjustment circuit 21 based on the received signals from the first and second monitoring modules 3 and in conjunction with preset stripping parameters, thereby achieving dynamic adjustment of stripping parameters and improving stripping accuracy. The cooperation of the motor drive module 2, the first monitoring module 3, and the second monitoring module 4 enhances the stability and accuracy of stripping.
[0042] In one embodiment, the first monitoring module 3 includes an optocoupler switch. In the above structure, the optocoupler switch can determine the limit state of the drive motor 22 by detecting obstruction. When the drive motor 22 reaches the limit position, an obstruction on the drive motor 22 can block the light from the optocoupler switch, causing the phototransistor to be cut off and output a high level to the adjustment circuit 1; conversely, when the light from the optocoupler switch is unobstructed, the phototransistor is turned on and outputs a low level to the adjustment circuit 1. Therefore, the optocoupler switch can detect the limit state of the motor in real time and transmit the state information to the adjustment circuit 1, ensuring that the motor operates within a safe range and avoiding jamming or damage caused by complex mechanical structures. In addition, the isolation characteristics of the optocoupler switch can effectively reduce electromagnetic interference in the motor drive circuit, which can improve the stability and reliability of the system; the optocoupler switch has a simple structure, is easy to install, and can be directly connected to the adjustment circuit 1; the optocoupler switch can effectively obtain the limit state of the drive motor 22 and transmit it to the adjustment circuit 1, thereby realizing precise control of the motor's operating state.
[0043] In one embodiment, the second monitoring module 4 includes a Hall sensor. In the above structure, the adjustment circuit 1 reads the output signal of the Hall sensor to determine whether a magnetic field exists. When the magnetic field strength exceeds a preset threshold, the Hall sensor outputs a signal; when the Hall sensor detects a change in the magnetic field of the drive motor, the output signal changes. When the magnetic field signal received by the adjustment circuit 1 is abnormal (e.g., the signal strength exceeds a preset electrical signal range), the adjustment circuit 1 can determine that it is an erroneous operation and trigger the alarm module 5 to issue an alarm.
[0044] In one embodiment, the fiber stripping control circuit further includes an alarm module 5, which is electrically connected to the adjustment circuit 1. The adjustment circuit 1 is used to trigger the alarm module 5 to issue an alarm message based on the limit status signal of the first monitoring module 3 and / or the magnetic field signal of the second monitoring module 4. In the above structure, when the drive motor 22 exceeds the limit position (e.g., the drive motor 22 is stuck and the optocoupler blockage is not released), the optocoupler switch outputs a high-level signal. The adjustment circuit 1 can judge the limit status signal based on a preset algorithm (e.g., threshold comparison). If the limit status signal output by the first monitoring module 3 exceeds the preset threshold range of the limit status signal, it is determined that the drive motor 22 is in an abnormal limit state, and the adjustment circuit 1 triggers the alarm module 5 to issue an alarm message. If the drive motor 22 stalls or overheats, the Hall sensor can detect a change in the magnetic field signal of the drive motor 22, such as a sudden change or abnormal fluctuation in the magnetic field. The adjustment circuit 1 can judge the magnetic field signal based on a preset algorithm. If the magnetic field signal output by the second monitoring module 4 exceeds the preset threshold range of the magnetic field signal, it is determined that the drive motor 22 is faulty, and the adjustment circuit 1 triggers the alarm module 5 to issue an alarm message. Alarm information may include sound, light, or voice information.
[0045] In one embodiment, the alarm module includes a buzzer for providing audible alarm information.
[0046] In one embodiment, the motor drive module 2 further includes at least two drive circuits 23, which are connected in series with the adjustment circuit 1; each drive circuit 23 is connected to one or more drive motors 22. In the above structure, the adjustment circuit 1 and the at least two drive circuits 23 are connected in a daisy-chain pattern, which means that the at least two drive circuits 23 are connected in series and then connected in series with the adjustment circuit 1; the control signal sent by the adjustment circuit 1 passes through each drive circuit 23 in sequence, and then drives the corresponding drive motor 22 through the drive circuit 23, thereby achieving synchronous control of the drive motor 22, simplifying the circuit design and reducing the complexity of the fiber stripping control circuit.
[0047] Specifically, the series-connected drive circuits 23 sequentially receive control commands from the adjustment circuit 1. After receiving the command, the first drive circuit 23 can perform preliminary processing based on its own functions, such as adjusting and amplifying the signal according to its own characteristics and configuration to ensure accurate driving of the connected drive motor 22. The processed signal is then passed to the next series-connected drive circuit 23. Each drive circuit 23 is connected to one or more drive motors 22, controlling their operation by transmitting the processed drive signal to the motor. Because the drive circuits 23 are connected in series, each drive circuit 23 can achieve coordinated movement of two or more drive motors 22 under the unified command of the adjustment circuit 1. For example, during fiber stripping, one drive motor 22 can drive the optical fiber to rotate, while another drive motor 22 drives the blade. Through the coordinated operation of the series-connected drive circuits 23, the synchronous movement of the two drive motors 22 can be ensured, thereby achieving precise fiber stripping. Therefore, by connecting multiple drive circuits 23 in series, the drive signal can be adjusted and processed more precisely, allowing each drive circuit 23 to optimize the signal according to its own characteristics. This results in a more accurate signal transmitted to the drive motor 22, improving the motor's control precision. For example, when controlling the motor's speed, the coordinated action of multiple adjustment circuits 21 can achieve more precise speed regulation, reduce speed fluctuations, and thus improve the fiber stripping precision.
[0048] In one embodiment, the adjustment circuit 1 has a first output interface and a first input interface. One end of the drive circuit 23 is connected to the first output interface, and the other end of the drive circuit 23 is connected to the first input interface. Both the first output interface and the first input interface use serial communication interfaces. In this structure, the adjustment circuit 1 is connected in series with the drive circuit 23 through the first output interface and the first input interface, enabling the adjustment circuit 1 to quickly send control signals, thus improving the response speed and control accuracy of the circuit system. Both the first output interface and the first input interface use serial communication interfaces (i.e., SPI interfaces). The adjustment circuit 1 communicates with the drive circuit 23 through the SPI interface; that is, the adjustment circuit 1 sends control signals to the drive circuit 23 at one end through the first output interface (SPI interface), while the drive circuit 231 at the other end forms a loop with the adjustment circuit 1 through the first input interface (SPI interface). Through the high-speed communication of the SPI interface, the adjustment circuit 1 can achieve synchronous control of multiple drive circuits 23, ensuring the coordinated movement of multiple motors and avoiding trajectory jitter caused by delay, thereby improving fiber stripping accuracy.
[0049] In one embodiment, the adjustment circuit 1 employs a microcontroller with a double-precision floating-point unit. In the above structure, the adjustment circuit 1 uses a microcontroller with a double-precision floating-point unit primarily to improve the control accuracy and performance of the fiber stripping control circuit. The double-precision floating-point unit provides higher computational accuracy. During fiber stripping, even small errors can lead to a significant decrease in stripping accuracy, while the double-precision floating-point unit can effectively reduce such errors. The fiber stripping control circuit needs to monitor and adjust the motor's operating status in real time. The double-precision floating-point unit can quickly process complex mathematical operations, ensuring the accuracy and stability of real-time control, reducing reliance on external hardware accelerators, thereby reducing system complexity and cost. For example, the adjustment circuit 1 can use an STM32H743 microcontroller, which is based on the ARM Cortex-M7 core, has a clock speed of up to 480MHz, and features a double-precision floating-point unit.
[0050] In one embodiment, the drive circuit 23 can employ a drive chip that supports microstepping; the step angle resolution of the drive motor 22 ranges from greater than or equal to 0.007° to less than or equal to 0.18°. In the above structure, microstepping technology, by precisely controlling the winding current of the drive motor 22, subdivides the traditional full step angle into multiple smaller step angles, thereby significantly improving the positioning accuracy of the drive motor 22; for example, each full step angle is subdivided into 256 microsteps, referred to as 256 subdivision, where the step angle resolution is equal to 0.007°, thus improving the step angle resolution of the drive motor 22. For example, the drive circuit 23 can employ a drive chip of model TMC5041, which supports simultaneously or separately driving two bipolar stepper drive motors 22, supporting a resolution of up to 256 microsteps per full step, ensuring high-precision positioning.
[0051] In one embodiment, the fiber stripping control circuit further includes a crystal oscillator circuit module 1, which is electrically connected to each of the drive circuits 23, thereby providing a stable frequency for the drive circuits 23. The crystal oscillator circuit module 1 provides a precise clock signal to the drive circuits 23, serving as a synchronization reference for the digital circuits and ensuring that the drive circuits 23 can execute various operations, such as instruction execution and data transmission, in a precise time sequence. The stable clock signal enables the drive circuits 23 to accurately control the stepper motor's step angle resolution, thus achieving high-precision stepping control. In the fiber stripping control circuit, multiple drive circuits 23 need to work collaboratively. The unified clock signal provided by the crystal oscillator circuit module 1 ensures that the operating rhythms of these chips are consistent, enabling correct data transmission and interaction, and guaranteeing the coordinated operation of the entire system.
[0052] In one embodiment, the fiber stripping control circuit further includes a step-down module 6. The input terminal of the step-down module 6 is connected to an external power supply, and the output terminal of the step-down module 6 is electrically connected to the adjustment circuit 1. In the above structure, the step-down module 6 is used to step down the external power supply (such as a 12V power supply) to the low voltage (such as 5V / 3.3V) required by the first monitoring module 3 and the second monitoring module 4 through DC-DC conversion technology, so as to ensure the power supply stability of each module such as the adjustment circuit 1, the adjustment circuit 21, and the first monitoring module. For example, the step-down module 6 can use a DC-DC step-down chip of model JW5060T. The circuit formed by this DC-DC step-down chip has low ripple and can convert the input 12V voltage into stable 5V and 3.3V voltage outputs, providing a stable operating voltage for subsequent circuits.
[0053] In one embodiment, the fiber stripping control circuit further includes a human-machine interface module 8, which is communicatively connected to the adjustment circuit 1. In the above structure, the human-machine interface module 8 realizes bidirectional information interaction between the user and the fiber stripping control circuit through a hardware interface and a software interface. The human-machine interface module 8 may include input devices and output devices. Input devices may include a capacitive touch screen, physical buttons (emergency stop, reset), and a rotary encoder (for adjusting preset limit state parameters or magnetic field signal parameters). Output devices may include an LCD / LED display screen, which can be used to display the fiber stripping progress, motor status, and fault codes in real time. Output devices may also include status indicator lights, which can be used to indicate the device's running, standby, and alarm status using three-color LEDs. For example, the output device can use a 5-inch capacitive touch screen, which is convenient for users to operate while avoiding space occupation.
[0054] In one embodiment, the fiber stripping control circuit further includes a switching module 7, which is electrically connected to the step-down module 6. In the above structure, the switching module 7 serves as the power control hub of the fiber stripping control circuit, controlling the on / off state of the input power to the step-down module 6 through electromechanical or solid-state switching elements. For example, the switching module 7 can use field-effect transistors and transistors as switching transistors, controlling whether the voltage is output to the adjustment circuit 1 through high-low level switching.
[0055] In one embodiment, the fiber stripping control circuit further includes a storage module 9, which is electrically connected to the adjustment circuit 1. The storage module 9 stores the setting parameter data of the human-machine interface module 8. In the above structure, the storage module 9 is used to save parameters set by the user through the human-machine interface module 8, such as fiber stripping length, rotation speed, motor control parameters, etc. These parameters remain unchanged after the fiber stripping control circuit is turned off, ensuring that the fiber stripping control circuit can automatically run according to the previous settings upon the next startup. When the device starts, the adjustment circuit 1 reads the saved parameters from the storage module 9 and initializes the device according to these parameters. During device operation, the adjustment circuit 1 can read or update the data in the storage module 9 as needed. The storage module 9 can also be used to store preset threshold ranges for limit status signals and preset threshold ranges for magnetic field signals.
[0056] The technical solution of this application utilizes the adjustment circuit 21 and drive motor 22 in the motor drive module 2 to precisely control the rotation of the optical fiber and the movement of the blade. Simultaneously, the first monitoring module 3 acquires the limit state of the drive motor 22, and the second monitoring module 4 monitors the magnetic field change signal of the drive motor 22, providing real-time feedback on the motor's operating status. This allows the adjustment circuit 1 to adjust the drive signal sent to the adjustment circuit 21 based on the received signals from the first and second monitoring modules 3 and in conjunction with preset fiber stripping parameters, thereby achieving dynamic adjustment of the fiber stripping parameters and improving stripping accuracy. The cooperation between the motor drive module 2 and the monitoring module reduces the complexity of the equipment and improves the stability and accuracy of fiber stripping.
