The laser grating screw 1 comprises a screw body and a laser grating sensor, wherein a sensor hole is formed in the axial direction of the screw body, and the laser grating sensor is arranged in the sensor hole. The laser grating sensor is used for monitoring the displacement change of the grating on the screw body in real time and converting the displacement change into the change of the tension of the laser grating screw 1.
The four screws of the fastening clamp 8 for fixing the tower and the power tower 9 are usually arranged at one side of the power tower 9, and the laser grating screw 1 is only used for replacing one screw with the largest tension in the four screws, and the other three screws are only used for common screws, so that the strongest tension fluctuation response of an ADSS optical cable is ensured. In addition, fig. 1 is described by taking the case where the laser grating screw 1 is provided on the right side of the power tower 9 as an example, and in a specific implementation, when monitoring of the ADSS cable on the left side of the power tower 9 is required, it may be realized by replacing one of the fixing tower fastening jig 8 and the screw of the power tower 9 with the laser grating screw 1. The laser grating screw 1 is horizontally and radially stressed when the fastening clamp 8 for the fixing tower is arranged, so that the change of the tension of the ADSS optical cable can be determined according to the change of the grating displacement acquired by the laser grating screw 1. The control device 3 is a device with a certain calculation function, such as an embedded chip or a singlechip, and the purpose of encoding the electric signals is to convert the electric signals into a format supporting the transceiver of the first global Beidou navigation satellite system 4 and the second global Beidou navigation satellite system 6. The coded electrical signals sent to the server 7 by the first global Beidou navigation satellite system 4 and the second global Beidou navigation satellite system 6 comprise the tension information of the laser grating screw 1, and also comprise the position of the power tower 9 where the first global Beidou navigation satellite system 4 is located, namely the position where the laser grating screw 1 is located. The second global beidou navigation satellite system 6 communicates with the first global beidou navigation satellite system 4 on a plurality of power towers 9, so that the server 7 can receive the coded electrical signals from the respective power towers 9. After the server 7 receives the encoded electric signals, the encoded electric signals are analyzed first to obtain the tension of the laser grating screw 1 and the position of the electric power tower 9 at each encoded electric signal transmission moment, and then, whether the ADSS optical cable 10 tensioned by the laser grating screw 1 fails or not is determined according to the tension of the laser grating screw 1, and the failure type is determined. In addition, the server 7 receives the encoded electric signals and stores the signals in real time, so that the subsequent inquiry and retrieval are facilitated, the large data of the tension of the laser grating screw 1 can be accumulated, and whether and what type of faults occur in the ADSS optical cable 10 can be determined according to the encoded electric signals.
Optionally, the server 7 is a GIS background management system. Because the encoded electric signals received by the server 7 include the tension information of the laser grating screw 1 and the position of the power tower 9 where the laser grating screw 1 is located, the position information of the power tower 9 can be displayed on a GIS map through a GIS background management system, so that the position of the power tower 9 can be intuitively determined, and the position of the failed ADSS optical cable 10 and the information of peripheral equipment can be conveniently positioned.

In this case, the control device 3 controls the charging time and the charging time of the solar sailboard 11 to the storage battery 12, and the storage battery 12 supplies power to the laser grating decoder 2, the control device 3 and the first global Beidou navigation satellite system 4. When the storage battery 12 supplies power to the laser grating decoder 2, the control device 3 and the first global Beidou navigation satellite system 4, the voltage of the storage battery 12 is converted into the voltages required by the laser grating decoder 2, the control device 3 and the first global Beidou navigation satellite system 4 through the DC-DC converter 15.
Optionally, the ADSS cable monitoring system based on laser grating screws further comprises a workstation 13, and the workstation 13 is connected with the server 7. If the server 7 determines that the ADSS optical cable 10 tensioned by a laser grating screw 1 fails and determines the type of the failure, the server 7 controls the workstation 13 to alarm, and timely reminds a worker to perform operations such as repairing the failed ADSS optical cable 10. The workstation 13 may alarm by sound, may alarm by light emission, may alarm by sound and light, etc.
Optionally, the laser grating screw 1 is connected with the laser grating decoder 2 through an armored soft optical fiber, so that the soft optical fiber is protected, and the laser grating screw 1 is ensured to be capable of sending a tension signal to the laser grating decoder 2.
Optionally, the laser grating decoder 2, the control device 3 and the first global Beidou navigation satellite system 4 are integrated in a waterproof box 14, and the waterproof box 14 is arranged at the upper part of the power tower 9.

The fault types of the ADSS optical cable comprise sliding, winding, breakage, excessively low sag, icing in winter and the like, and the tension conditions of the ADSS optical cable are different when different types of faults occur in different weather ADSS optical cables. Therefore, in this embodiment, the server 7 gathers the tension data of the ADSS cable under different weather conditions at different locations and the state of the ADSS cable at that time in advance to build a classification model of the correspondence between the location, the tension, the weather condition and the ADSS cable state (including the normal state and the different types of fault states). The method can be implemented based on some current classification model training algorithms when the classification model is built, which is not described in detail in this embodiment. On the basis, when the system is used, the laser grating screw 1 feeds back the tension to the laser grating decoder 2 in real time, the laser grating decoder 2 converts the tension into an electric signal at regular time and sends the electric signal to the control device 3, the control device 3 encodes the electric signal and then sends the encoded electric signal to the second global navigation satellite system 6 through the first global navigation satellite system 4 (for example, every half hour or one hour, etc.), the second global navigation satellite system 6 sends the encoded electric signal to the server 7, the server 7 acquires the weather condition of the position of the laser grating screw 1, and the tension and the weather condition are input into a pre-established classification model, so that whether the ADSS optical cable 10 tensioned by the laser grating screw 1 has faults and the fault type can be output by the classification model.
