Description

Technical Field

[0001] This utility model relates to the field of optical cable fault diagnosis technology, specifically to an automatic diagnostic instrument for optical cable faults in remote I / O stations. Background Technology

[0002] In industrial automation control systems, smart manufacturing production lines, and large-scale industrial scenarios, remote I / O (input / output) stations serve as core nodes connecting field sensors and actuators with the central control system, undertaking crucial functions such as data acquisition and command transmission. Since remote I / O stations are typically deployed in field areas far from the central control room, data interaction between them and the central system largely relies on fiber optic cables. Compared to traditional cables, fiber optic cables offer advantages such as high transmission speeds, strong resistance to electromagnetic interference, and low signal attenuation, meeting the stable transmission requirements of massive amounts of data in industrial scenarios. Therefore, they have become the core carrier of the data link for remote I / O stations. However, optical cables are susceptible to failure due to the complex environmental factors in industrial settings during long-term use. Current methods for diagnosing optical cable faults largely rely on manual on-site inspections using specialized testing equipment, but this approach has the following drawbacks: First, the diagnostic timeliness is poor, and manual on-site inspection is required after the fault occurs, which not only delays the fault repair, but also has high manual inspection costs; second, real-time monitoring cannot be achieved, making it difficult to provide early warning of potential faults, and can only be passively investigated after the fault occurs.

Detailed Implementation

[0023] To better understand the purpose, structure, and function of this utility model, the following detailed description of the automatic diagnostic instrument for optical cable faults in remote I / O stations provided by this utility model is provided in conjunction with the accompanying drawings, so that those skilled in the art can better understand and implement this utility model. However, the embodiments described are not intended to limit this utility model.

[0024] Please see Figures 1 to 6As shown in the embodiment of this application, an automatic diagnostic instrument for optical cable faults in a remote I / O station is provided, including an upper housing 10, a lower housing 20, and a limiting mechanism 30 for limiting and fixing the upper housing 10 and the lower housing 20. The upper housing 10 is located above the lower housing 20 and is hinged to the lower housing 20. A first groove 11 is provided at the bottom of the upper housing 10. A second groove 21 corresponding to the first groove 11 is provided at the top of the lower housing 20. Two first rollers 12 arranged at intervals are rotatably connected to the first groove 11 along its length. A driving mechanism 40 for driving the first rollers 12 to rotate is provided on the upper housing 10. Two second rollers 22 corresponding to the two first rollers 12 are rotatably connected in the second groove 21, and a detector 23 is provided in the second groove 21. An optical cable groove is formed between the first rollers 12 and the second rollers 22. The detector 23 can perform fault diagnosis and real-time monitoring of the optical cable 50 to be tested, and send the diagnosis and monitoring results to the control center through the data transmission module built into the detector 23.

[0025] Because it is equipped with an upper housing 10, a lower housing 20, and a limiting mechanism 30, and the upper housing 10 has a first groove 11 and a driving mechanism 40, with a first roller 12 installed in the first groove 11, and the lower housing 20 has a second groove 21, with a second roller 22 and a detector 23 installed in the second groove 21, the cooperation between the above components allows the upper housing 10 and the lower housing 20 to rotate around their hinge point in a direction that moves closer to or further away from each other. This enables the remote I / O station optical cable fault automatic diagnostic instrument to be mounted on or removed from the optical cable 50 to be tested. The operation is simple and convenient, greatly improving the assembly and disassembly efficiency of the remote I / O station optical cable fault automatic diagnostic instrument. Simultaneously, in conjunction with the limiting mechanism 30, after the remote I / O station optical cable fault automatic diagnostic instrument is assembled onto the optical cable 50 to be tested, the upper housing 10 and the lower housing 20 are limited and fixed to prevent the remote I / O station optical cable fault automatic diagnostic instrument from falling off, thereby improving the operational stability of the remote I / O station optical cable fault automatic diagnostic instrument and ensuring that the diagnostic work of the detector 23 can be carried out normally. In addition, through the coordinated use of the first roller 12, the second roller 22 and the drive mechanism 40, the remote I / O station optical cable fault automatic diagnostic instrument can automatically move along the outer surface of the optical cable 50 to be tested, realizing the automatic diagnosis and real-time monitoring of faults in the optical cable 50 by the detector 23, greatly improving the diagnostic efficiency of optical cable faults.

[0026] In a preferred embodiment, the limiting mechanism 30 includes an L-shaped locking plate 31, a connecting seat 32, and a limiting rod 33; the upper end of the L-shaped locking plate 31 is fixed to the side wall of the upper housing 10, the lower end of the L-shaped locking plate 31 extends downward, and a locking post 31a extends from the inner side wall of the lower end of the L-shaped locking plate 31 to the side of the upper housing 10; the connecting seat 32 is fixed to the top of the lower housing 20 and corresponds to the L-shaped locking plate 31; one end of the limiting rod 33 is rotatably connected to the connecting seat 32, and the other end can rotate into the L-shaped locking plate 31 and be locked onto the locking post 31a.

[0027] Since the limiting mechanism 30 is equipped with an L-shaped clamping plate 31, a connecting seat 32, and a limiting rod 33, through the cooperation of the above components, after the upper housing 10 and the lower housing 20 clamp the optical cable 50 to be tested in the optical cable groove, the limiting rod 33 can be rotated into the L-shaped clamping plate 31 and locked onto the clamping post 31a to limit and fix the upper housing 10 and the lower housing 20 to prevent them from falling off the optical cable 50 to be tested.

[0028] In a preferred embodiment, the limiting mechanism 30 further includes a limiting cylinder 34, a pull rod 35, a limiting ring 36, and a spring 37; the limiting cylinder 34 is fixed to the outer wall of the L-shaped clamping plate 31; the pull rod 35 is coaxially arranged with the limiting cylinder 34, with one end of the pull rod 35 located outside the limiting cylinder 34, and the other end movably passing through the limiting cylinder 34 and the L-shaped clamping plate 31, and can be inserted into the insertion hole 33a of the limiting rod 33; the limiting ring 36 is located inside the limiting cylinder 34 and fixed to the outer peripheral wall of the pull rod 35; the spring 37 is fixed to the side of the limiting ring 36 away from the L-shaped clamping plate 31 and sleeved on the outside of the pull rod 35. In this embodiment, the limiting mechanism 30 is provided in two sets, and the two sets of limiting mechanisms 30 are arranged symmetrically to each other.

[0029] Since the limiting mechanism 30 is also equipped with a limiting cylinder 34, a pull rod 35, a limiting ring 36, and a spring 37, through the cooperation of the above components, after the limiting rod 33 is snapped onto the locking post 31a, the pull rod 35 is inserted into the insertion hole 33a of the limiting rod 33 to further limit and fix the limiting rod 33, improve the connection stability between the limiting rod 33 and the L-shaped locking plate 31, and further improve the connection stability between the upper housing 10 and the lower housing 20. Specifically, before snapping the limiting rod 33 onto the locking post 31a, the pull ring of the pull rod 35 is pulled outward to move the pull rod 35 away from the upper housing 10. At this time, the spring 37 is compressed. After the limiting rod 33 is snapped onto the locking post 31a, the pull rod 35 is released. The spring 37 returns to its original position and simultaneously drives the pull rod 35 to return to its original position and insert into the insertion hole 33a at the upper end of the limiting rod 33, thus completing the limiting and fixing of the limiting rod 33. Conversely, during disassembly, pulling the lever 35 will disengage the limit rod 33 from the L-shaped clamping plate 31, making the operation simple and convenient and greatly improving the disassembly and assembly efficiency between the upper housing 10 and the lower housing 20.

[0030] In a preferred embodiment, the side wall of the limiting rod 33 away from the connecting seat 32 is provided with a slot 33b for engaging with the locking post 31a. Because the limiting rod 33 has the slot 33b, after rotating into the L-shaped locking plate 31, the limiting rod 33 can engage with the locking post 31a through the slot 33b, thus achieving initial fixation between the limiting rod 33 and the L-shaped locking plate 31.

[0031] In a preferred embodiment, the drive mechanism 40 includes a drive wheel 41, a driven wheel 42, a timing belt 43, and a drive motor 44; a transmission groove 13 is provided on the bottom of the upper housing 10 near the limiting mechanism 30; the drive wheel 41 and the driven wheel 42 are respectively located in the transmission groove 13, and are respectively connected to the rotating shafts of the two first rollers 12 near one end of the transmission groove 13; the drive wheel 41 and the driven wheel 42 are connected by the timing belt 43; the drive motor 44 is fixed on the outer side wall of the upper housing 10, and the output shaft of the drive motor 44 is connected to the drive wheel 41.

[0032] Since the drive mechanism 40 is equipped with a driving wheel 41, a driven wheel 42, a synchronous belt 43, and a drive motor 44, the drive motor 44 drives the driving wheel 41 to rotate, and the synchronous belt 43 drives the two first rollers 12 to rotate, thereby enabling the first rollers 12 to move on the surface of the optical cable 50 to be tested. By controlling the operation of the drive motor 44, the testing personnel can move the remote I / O station optical cable fault automatic diagnostic instrument to the designated position of the optical cable 50 to be tested. The operation is flexible and controllable, greatly improving the flexibility of optical cable fault diagnosis.

[0033] In a preferred embodiment, a rotating plate 14 extends downward from the bottom of the upper housing 10 away from the transmission groove 13; a hinge seat 24 corresponding to the rotating plate 14 is provided on the top of the lower housing 20; the upper housing 10 is hinged to the hinge seat 24 via the rotating plate 14. Since the upper housing 10 and the lower housing 20 are respectively provided with the rotating plate 14 and the hinge seat 24, the upper housing 10 and the lower housing 20 can rotate towards or away from each other through the cooperative use of the rotating plate 14 and the hinge seat 24, thereby driving the first roller 12 and the second roller 22 to clamp or move away from the optical cable 50 to be tested. The operation is simple and convenient, improving the efficiency of disassembly and assembly between the upper housing 10 and the lower housing 20, while also improving the fault diagnosis efficiency of the optical cable 50 to be tested.

[0034] In a preferred embodiment, a power supply compartment 25 is formed on the side wall of the second groove 21, and a power supply 26 is disposed inside the power supply compartment 25. The power supply 26 is electrically connected to the detector 23. Since the second groove 21 is provided with a power supply compartment 25, it can be used to install the power supply 26, and the power supply 26 supplies power to the detector 23 and the drive motor 44.

[0035] In this embodiment of the application, an automatic diagnostic instrument for optical cable faults at a remote I / O station is used by first rotating the upper housing 10 and the lower housing 20 around the hinge seat 24 in a direction that brings them closer together, so that the first roller 12 and the second roller 22 are brought closer together to clamp the optical cable 50 to be tested in the optical cable groove. Then, the pull rod 35 is pulled, and at the same time, the free end of the limiting rod 33 is rotated into the L-shaped clamping plate 31 and locked onto the clamping post 31a. Then, the pull rod 35 is released, and the spring 37 resets the pull rod 35 to insert it into the insertion hole 33a of the limiting rod 33. Finally, the detector 23 is activated, and the operation of the drive motor 44 is controlled to drive the first roller 12 and the second roller 22 to rotate, and synchronously move the detector 23 to the designated position on the optical cable 50 to be tested, thereby realizing the automatic diagnosis of optical cable faults.
