Embodiment 1

[0033] The first embodiment of the present invention proposes a transmission line protection method, including:

[0034] An inclination angle sensor is installed on the tower of the power transmission line to detect the inclination angle of the tower, and send it to the remote control center; and work according to the control signal of the remote control center.

[0035] In the embodiment of the present invention, the inclination angle of the transmission line tower is tested by the inclination angle sensor, and an alarm signal is sent when the inclination angle exceeds a preset value. In this way, the status of the tower can be automatically detected, and an alarm will be given when the tower is tilted. Compared with the visual inspection method in the prior art, the embodiments of the present invention can improve the accuracy, and can send out an alarm signal when the tower just tilts, so as to prevent accidents. At the same time, compared with the manual inspection method...

Embodiment 2

[0037] The second embodiment of the present invention is improved on the basis of the first embodiment, that is, the tilt angle sensor received in the first embodiment can be directly sent to the remote control center without any processing; By setting the client on the sub-tower to process the data locally, when an abnormality is found, an alarm message is sent to the control center. That is, the method also includes:

[0038] Reading the data of the inclination angle sensor, and judging whether the data exceeds a preset threshold, and if so, sending a control signal to the remote control center.

[0039] In this way, the amount of data transmission and the processing amount of the remote control center can be reduced, so as to save system overhead and network transmission overhead.

[0040] Further, the client installed on the tower needs to periodically send a heartbeat signal, so that the remote control center knows that the client is connected normally.

[0041] Wherein...

Embodiment 3

[0046] The third embodiment of the present invention proposes a transmission line protection system, including:

[0047] An inclination sensor 1 is arranged on the tower to detect the inclination angle of the tower;

[0048] The control module 2 is used to receive the signal of the tilt angle sensor and send it through the data communication module; and receive the control signal received by the data communication module, and generate a control command according to the control signal;

[0049] The data communication module 3 is used to send the received data to the remote control center; and receive the control signal from the remote control center and send it to the control module.

[0050] In the embodiment of the present invention, the inclination angle of the transmission line tower is tested by the inclination angle sensor, and an alarm signal is sent when the inclination angle exceeds a preset value. In this way, the status of the tower can be automatically detected, an...

Abstract

The invention provides a method and a system for protecting a power transmission line, belonging to the technical field of communication. The embodiment comprises the steps of testing an inclination angle of a pole of the power transmission line through an inclination angle sensor, emitting an alarm signal when the inclination angle exceeds the preset value and working according to a control signal of a remote control center. Therefore, the method and the system can automatically detect the state of the pole, and alarm when the pole is inclined. Compared with the visual measurement way in the prior art, the embodiment can improve the accuracy, immediately emit the alarm signal when the pole is just inclined and further prevent accidents. Simultaneously, the embodiment has better real-time property in comparison with the manual patrol way.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for protecting a power transmission line. Background technique [0002] Electricity is undoubtedly indispensable to modern life, and electricity must be transported through the grid, so transmission lines are very important. Due to the wide geographical distribution of our country and the complex and diverse address conditions, when the transmission line passes through special areas such as coal mining areas, soft soil areas, hillside areas, riverbed areas, etc., under the action of natural conditions, the tower foundation often slips and tilts , settlement, cracking and other phenomena, which will cause deformation or inclination of the tower and affect the normal operation of the transmission line. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] I...
