[0002] With the continuous development of fiber optic communication technology, the application areas of distributed fiber optic sensor communication networks are also constantly expanding. In power systems, they are used to monitor the temperature and stress of transmission lines to ensure the safe operation of the power grid; in the petrochemical industry, they are used to monitor pipeline leaks and structural safety; and in intelligent transportation systems, they are used to monitor the condition of roads and bridges, etc.

[0003] These application scenarios place higher demands on the accuracy, speed, and reliability of fault location. In actual communication network engineering, due to the large number of fiber optic patch cords, existing patch cords must be checked one by one before performing new patching operations or during actual fault diagnosis. By connecting a fault detection device to both ends of the patch cord, the various indications given by the fault detection device are observed to determine whether the network link connectivity is normal. This is a meticulous and important task. Therefore, to meet market demand, this utility model designs a communication network fault location device that can detect fiber optic patch cords more quickly and accurately to identify fault locations.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-7 This utility model provides a technical solution for a fault location device for a distributed optical fiber sensor communication network: A fault location device for a distributed optical fiber sensor communication network includes a control panel 1 and a main frame 3. The control panel 1 is arranged on the front of the main frame 3; a display screen 2 is arranged on the upper part of the front of the main frame 3; a clamping mechanism is arranged at the upper end of the main frame 3, the clamping mechanism includes a gripper 4, and a fixing frame 13 is fixedly connected to the lower part of the gripper 4. The fixing frame 13 is fixedly connected to the main frame 3; a driven wheel 6 is arranged at the lower end of the fixing frame 13, the driven wheel 6 is rotatably connected to the main frame 3, a detection unit 9 is slidably connected inside the driven wheel 6, a limit block 11 is arranged on the outer side of the detection unit 9, and a return spring 10 is arranged at the lower end of the limit block 11; a drive motor 7 is arranged below the driven wheel 6, and an active friction wheel 8 is arranged at the upper end of the drive motor 7. The driven wheel 6 and the active friction wheel 8 are rotatably connected.

[0022] The driven wheel 6 has a groove inside that corresponds to the limit block 11. The upper end of the return spring 10 contacts the limit block 11, and the lower end of the return spring 10 contacts the lower end surface of the groove.

[0023] The driven wheel 6 and the detection unit 9 are concentrically arranged and both are cylindrical in shape. The center line of the driven wheel 6 coincides with that of the fixed frame 13.

[0024] The rotation of the active friction wheel 8 drives the driven wheel 6 to rotate via friction transmission. The rotation of the driven wheel 6 drives the detection unit 9 to rotate. The internal gripper 4 holds the fiber optic connector 12. After the detection unit 9 rotates, it is threadedly connected to the fiber optic connector 12. The gripper 4 is pneumatically driven by an air pump installed inside the main frame 3. The internal structure diagram of the gripper 4 is shown below. Figure 6 As shown, the principle by which the gripper 4 holds the object is existing technology.

[0025] A bracket 5 is rotatably mounted on the back of the main frame 3, and three sets of grippers 4 are evenly arranged on the upper surface of the fixed frame 13; the drive motor 7 is fixedly connected to the main frame 3.

[0026] The working principle and usage process of this utility model are as follows: When using this utility model, the fiber optic connector 12 to be tested is placed sequentially inside the clamp 4. Under the grip of the clamp 4, the fiber optic connector 12 can maintain alignment with the center line of the clamp 4 and the detection unit 9 below it. The drive motor 7 is then rotated by controlling the control buttons on the control panel 1. Figure 6 and Figure 7 As shown, the drive motor 7 drives the active friction wheel 8 at the output end to rotate synchronously. Under the drive of the active friction wheel 8, the driven wheel 6 rotates accordingly. Since the lower end of the fiber optic connector 12 must be kept pressing down on the detection unit 9 to ensure contact between the two when placing the fiber optic connector 12, the rotation of the driven wheel 6 will drive the detection unit 9 to rotate. The upper end of the detection unit 9 is provided with an external thread, which is threaded to the lower end of the fiber optic connector 12. When the detection unit 9 and the fiber optic connector 12 are threaded together, the detection unit 9 will slide upward inside the driven wheel 6 through the limit block 11 until the detection unit 9 and the fiber optic connector 12 are threaded together. Then, the control panel 1 is connected and the detection unit 9 is run to perform optical path detection operation. The detection result of the detection unit 9 is then displayed on the display screen 2. Although this invention does not improve the detection unit 9, by setting an improved clamping mechanism in the fiber optic sensor communication network fault location device, the steps of plugging and unplugging the connector can be simplified. In particular, for threaded connectors, the drive motor inside the device drives the active friction wheel and the driven wheel to rotate, thereby realizing the rapid connection between the detection unit and the fiber optic connector. Using this device, the operation process of the testing personnel is simplified, the testing efficiency is improved, and misjudgments caused by inaccurate connector connection are avoided.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
