Technical Field

[0001] The present invention relates to the technical field of visual online monitoring of power transmission line channels, and in particular to a method and system for calculating the coverage rate of a visual monitoring device for power transmission lines. Background Art

[0002] As the demand for electricity in various industries continues to grow, the length of transmission lines is also growing rapidly. Overhead lines are widely distributed, and the safety of overhead line channels is particularly important. Visual monitoring of transmission overhead lines has been widely used as an important means of safety assurance. Remote monitoring through visualization devices can reduce the workload of patrol and maintenance to a certain extent. However, the current visualization installation cost is high and it is impossible to cover the entire line.

[0003] Therefore, it is necessary to propose a method and system for calculating the coverage rate of a visual monitoring device for a transmission line to achieve comprehensive coverage of the entire transmission line under a visual monitoring network. Summary of the invention

[0047] Example:

[0048] Since the visual monitoring device is installed at each tower node of the transmission line, its monitoring range covers the channel space from the tower to the adjacent target tower. Therefore, the installation direction of the device determines which adjacent tower is monitored, which has a direct impact on the monitoring viewing angle and coverage effect. In addition, in the tower cluster area with compact line structure, a single visual monitoring device can realize the simultaneous monitoring of multiple tower channels with the appropriate installation angle and wide field of view.

[0049] In this embodiment, the method for calculating the coverage rate of the visual monitoring device for power transmission lines is specifically implemented as follows: Figure 1 As shown, the following steps are included:

Therefore, it is necessary to find towers that are not directly monitored, that is, the secondary coverage area.

[0068] S8: Take set G i With set C i The difference set H i ,like Figure 3 The following is the secondary coverage area of ​​the visual monitoring device:

[0069] H i =G i -C i .
