[0035] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0036] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0037] Figure 1 A flowchart of a method for detecting a broken optical fiber is provided for an embodiment of the present invention. This embodiment can be applied to the case where a sudden broken optical fiber is automatically detected during the production process of an optical fiber cable. The method for detecting a broken optical fiber can be performed by an optical fiber detection device. The optical fiber detection device can be implemented in the form of hardware and / or software. The optical fiber detection device can be configured in an optical fiber cable production device. The method for detecting a broken optical fiber is applied to an optical fiber pay-off system. The optical fiber pay-off system includes an optical fiber pay-off frame, an optical fiber reel fixed on the optical fiber pay-off frame, and a dancing wheel fixed on the optical fiber pay-off frame and pulled up by the optical fiber. The optical fiber pay-off frame includes a pay-off frequency converter and a pay-off motor. Figure 1 As shown, the optical fiber disconnection detection method includes:

[0038] S110. In the process of producing optical fiber and optical cable, the current running speed of the pay-off motor controlled by the pay-off inverter is obtained in real time, and the current position of the dancing wheel is detected in real time.

[0039] Due to problems with the optical fiber and cable production equipment itself or optical fiber quality problems (for example, notches in the optical fiber itself, uneven outer diameter of the optical fiber and bulges), the optical fiber may suddenly break during the optical fiber and cable production process. If the optical fiber break is not discovered in time, it will lead to continuous optical fiber waste in the optical fiber and cable production line. Based on the above problem, this embodiment automatically detects and alarms for optical fiber breakage in two situations: the part where the optical fiber is in contact with the optical fiber and cable production equipment and the part where the optical fiber is not in contact with the optical fiber and cable production equipment.

[0040] The pay-off frequency converter is used to output the corresponding frequency according to the driving signal provided by the dancing wheel to change the speed of the pay-off motor. That is, the pay-off frequency converter can control the current running speed of the pay-off motor, thereby making the optical fiber reel pay out the optical fiber at a certain linear speed.

[0041] The current running speed is the running speed of the motor that controls the optical fiber to be released from the optical fiber reel. The current running speed is calculated by the pay-off frequency converter combined with the movement of the dancing wheel. This embodiment does not impose any limitation on the specific calculation method.

[0042] If the optical fiber is broken at a location that is not in contact with the optical fiber cable production equipment, the optical fiber will suddenly lose all tension, and due to the influence of gravity, the dancing wheel will fall to a vertical position, which is the limit position of the dancing wheel. This limit position can also be understood as the lowest position that the dancing wheel can reach. Specifically, if the current position of the dancing wheel is at the limit position of the dancing wheel, that is, the dancing wheel falls to the lowest position, it can be determined that the optical fiber is broken at a location that is not in contact with the optical fiber cable production equipment.

[0043] It is understandable that the limit position of the dancing wheel can be determined by the installation position of the dancing wheel and other factors, that is, the limit position of the dancing wheel can be determined after the dancing wheel is fixed on the optical fiber pay-off frame, and this embodiment does not impose any limitation on this.

[0044] The current position of the dancing wheel can be detected in real time by a position sensor, and the position sensor is installed on the optical fiber pay-off frame. Considering the different installation positions of the position sensor, it will affect the judgment of whether the current position of the dancing wheel is at the limit position according to different position standards. In one embodiment, if the position sensor is installed at the limit position of the dancing wheel, the position sensor can use a proximity sensor, that is, the proximity sensor is used to detect whether the current position of the dancing wheel is at the limit position; in another embodiment, if the position sensor is installed at a position other than the limit position of the dancing wheel, the current position of the dancing wheel can be detected by a conventional position sensor, and then it is judged whether it is at the limit position according to the obtained current position of the dancing wheel.

[0045] S120, judging whether the optical fiber is broken at a position in contact with the optical fiber and cable production equipment during the optical fiber and cable production process according to the current running speed, and judging whether the optical fiber is broken at a position not in contact with the optical fiber and cable production equipment according to the current position.

[0046] On the basis of the above, if the current position of the dance wheel is at the limit position of the dance wheel, it is considered that the optical fiber is broken at a position that is not in contact with the optical fiber cable production equipment; conversely, if the current position of the dance wheel is not at the limit position of the dance wheel, the dance wheel is in normal operation, and it is not considered that the optical fiber is broken at a position that is not in contact with the optical fiber cable production equipment.

[0047] In this embodiment, if the optical fiber is broken at the part in contact with the optical fiber cable production equipment (such as the guide wheel, the guide wheel gap, the extruder head, the mold, etc.), the optical fiber will most likely be stuck at the contact part, so the optical fiber itself is still under stress, and the dancing wheel is still pulled and cannot fall off, but the optical fiber is broken at this time. The current running speed can be used to determine whether the optical fiber is broken at the part in contact with the optical fiber cable production equipment during the optical fiber cable production process.

[0048] In one embodiment, the current running speed of the pay-off motor can be controlled by the pay-off frequency converter to be compared with the current working speed of the optical fiber cable production line to determine whether they are consistent, thereby determining whether the optical fiber is broken at the position in contact with the optical fiber cable production equipment. Specifically: if the current running speed is inconsistent with the current working speed, it is determined that the optical fiber in the optical fiber cable production process is broken at the position in contact with the optical fiber cable production equipment; if the current running speed is consistent with the current working speed, it is determined that the optical fiber in the optical fiber cable production process is not broken at the position in contact with the optical fiber cable production equipment.

[0049] In another embodiment, the pay-off frequency converter can be used to control whether the current running speed of the pay-off motor changes suddenly, that is, whether the current running speed suddenly becomes particularly small, such as the current running speed may be a few tenths of the normal running speed, so as to determine whether the optical fiber is broken at the part in contact with the optical fiber cable production equipment. Specifically: if the current running speed is lower than the running speed limit, it is determined that the optical fiber in the optical fiber cable production process is broken at the part in contact with the optical fiber cable production equipment; if the current running speed is not lower than the running speed limit, it is determined that the optical fiber in the optical fiber cable production process is not broken at the part in contact with the optical fiber cable production equipment.

[0050] The operating speed limit is the minimum speed value that can occur when the optical fiber breaks at the part in contact with the optical fiber and cable production equipment. This embodiment does not impose any restriction on the specific value of the operating speed limit, and the operating speed limit can be jointly determined by the pay-off frequency converter and the pay-off motor.

[0051] Based on the above embodiment, when the optical fiber breaks at a position in contact with the optical fiber cable production equipment, or when the optical fiber breaks at a position not in contact with the optical fiber cable production equipment, an optical fiber break signal is generated to control the optical fiber cable production line to shut down based on the optical fiber break signal.

[0052] Considering that currently optical fiber breakage cannot be detected actively, that is, it relies on manual automatic detection, and sometimes even manual self-detection cannot detect it, the optical fiber breakage detection method of this embodiment can be applied to simultaneously perform optical fiber breakage detection on the optical fiber cable production process of multiple optical fiber cable production lines. Specifically, when multiple optical fiber cable production lines are simultaneously producing optical cables, the current operating speed of the pay-off motor controlled by the pay-off frequency converter on each optical cable production line is obtained in real time, and the current position of the dancing wheel on each optical cable production line is detected in real time, and then the optical fiber on each optical cable production line is judged according to the current operating speed whether the optical fiber is broken in the part that contacts the optical fiber cable production equipment, and the optical fiber on each optical cable production line is judged according to the current position whether the optical fiber is broken in the part that does not contact the optical fiber cable production equipment.

[0053] The technical solution of the embodiment of the present invention, the optical fiber disconnection detection method is applied to the optical fiber pay-off system, the optical fiber pay-off system includes an optical fiber pay-off frame, an optical fiber reel fixed on the optical fiber pay-off frame, and a dancing wheel fixed on the optical fiber pay-off frame and pulled up by the optical fiber, the optical fiber pay-off frame includes a pay-off frequency converter and a pay-off motor, in the optical fiber cable production process, the pay-off frequency converter controls the current running speed of the pay-off motor in real time, and the current position of the dancing wheel is detected in real time, and the optical fiber in the optical fiber cable production process is judged according to the current running speed whether the optical fiber is disconnected in the part that contacts the optical fiber cable production equipment, and the optical fiber is judged according to the current position whether the optical fiber is disconnected in the part that does not contact the optical fiber cable production equipment. The present invention can realize the automatic alarm of optical fiber disconnection in the optical fiber cable production process and the automatic shutdown of the optical fiber cable production line, effectively avoiding the generation of optical fiber waste and ensuring the yield rate of optical fiber cable production.
