Problems solved by technology

Identifying the high-incidence areas of the above alarms is helpful to improve the work efficiency of transmission line maintenance personnel. However, by manually setting the number of divided areas, the radius of the identified high-incidence areas is often quite different from the actual inspection radius of the inspection, which needs to be repeated.

Embodiment 2

[0038] The visual image alarm data of a power transmission line in a certain place has been pre-processed to obtain 3,265 weighted alarm data of cranes, of which 2,786 data in the last three months need to be identified for areas with high alarm occurrence, and transmission line maintenance personnel require high alarm occurrence The radius of area identification is 5000m, and the upper and lower errors are 5%. In this embodiment, based on the above data, the number of alarm area divisions will be automatically determined. The conditions can be sorted out, 1) the number of data that can be used as offline is 3265; 2) the data that can be used online is 2786; 3) the inspection radius R = 5000m; 4) the confidence interval is [0.95, 1.05].

[0039] For the number of alarm data, it is particularly pointed out that the alarm data is processed by weight, that is, the coordinate data of the same latitude and longitude are combined into one, and the weight value is used to represent t...

Embodiment 1

[0050] In Embodiment 1, the number of divisions of alarm areas is automatically determined, so that the identified high-incidence alarm areas conform to the inspection radius of transmission line maintenance personnel.

Embodiment 3

[0052] The visual image alarm of a transmission line in a certain place has been learned through offline training that the recommended value of the number of area divisions is 1118, and there are 3152 pieces of data in the past 6 months that need to be identified for high-alarm areas. Transmission line maintenance personnel require the identification of high-alarm areas The radius is 5000m, and the upper and lower errors are within 5%. In this embodiment, the number of warning areas will be automatically determined based on the suggested value and the above data, and the conditions can be sorted out. 1) The suggested value of area division is 1118; 2) The data used online is 3152; 3) The maintenance radius R= 5000m; 4) The confidence interval is [0.95,1.05].

[0053] This example already has suggested values, and there is no need to perform offline training again. The specific steps are as follows:

[0054] a. Based on the suggested value of 1118 to identify the high-alarm ar...

Abstract

The invention belongs to the field of power transmission line maintenance, and particularly relates to a method for determining the division number of visual alarm regions of a power transmission linechannel, which comprises the following steps of: a, performing offline training on a model based on visual alarm data of the power transmission line channel to obtain a suggested value; b, determining a determination value of the power transmission line channel visual alarm area division number through online decision. According to the method, the division number of the visual alarm regions of the power transmission line channel can be automatically determined, the visual alarm high-incidence regions of the power transmission line channel are identified based on the determined value, the coverage radius of the found visual alarm high-incidence regions conforms to the inspection radius of power transmission line maintainers, and convenience is brought to the power transmission line maintainers.

Description

technical field [0001] The invention belongs to the field of power transmission line maintenance, and in particular relates to a method for determining the number of divisions of visual alarm areas for transmission line channels. Background technique [0002] With the upgrading of transmission line maintenance technology, visual remote inspection of transmission line channels has been widely used. At present, it has realized the automatic identification of visual information and marked the warning objects appearing in the image, such as tower cranes, wildfires, excavators, etc. Identifying the high-incidence areas of the above alarms is helpful to improve the work efficiency of transmission line maintenance personnel. However, by manually setting the number of divided areas, the radius of the identified high-incidence areas is often quite different from the actual inspection radius of the inspection, which needs to be repeated. Adjustment. [0003] To sum up, how to provide...
