s100, acquiring a power transmission line image shot by a collecting device, and preprocessing the power transmission line image;
s200, inputting the preprocessed power transmission line image into a fully trained line detection model to obtain a line detection result;
and S300, sending corresponding alarm information based on the line detection result.
In this embodiment, a line detection result is obtained by acquiring an image of a power transmission line, processing the image, and outputting the processed image to a line detection model with complete training, and then, corresponding alarm information is sent out based on the line detection result. Can directly discern transmission line's anomaly through the image, realize patrolling and examining transmission line, increase the efficiency and the rate of accuracy of patrolling and examining, reduce artificial intensity of labour, avoid appearing the potential safety hazard, can patrol and examine the monitoring blind area that the manual work can't reach moreover, patrol and examine the coverage rate height.
In some embodiments, step S100 specifically includes:
acquiring a power transmission line image shot by acquisition equipment;
and carrying out shielding cutting on the image of the power transmission line so as to divide a scene contained in the image of the power transmission line into a plurality of different spatial levels and cut off invisible scene parts.
In this embodiment, the collection equipment can be the equipment that can shoot such as camera, unmanned aerial vehicle, when the installation, can be right collection equipment sets up, so that collection equipment carries out the collection of image regularly.
In order to reduce redundancy of subsequent models, the embodiment of the invention also performs occlusion clipping and application level detail division on the image, and specifically, the occlusion clipping and application level detail models are two effective three-dimensional complex scene rendering acceleration algorithms. In order to rapidly render a three-dimensional complex scene, the embodiment of the invention provides an algorithm framework combining a hierarchical detail model and an occlusion clipping technology, wherein the algorithm firstly divides the scene into different spatial hierarchical structures in a preprocessing stage; then, at the running time, for a higher spatial level, the visibility of the scene can be judged by applying a shielding cutting technology, and the invisible scene part is cut; at the local lower level, a mesh reduction method is applied to select the appropriate model level details.
In some embodiments, in step S200, the method for training the route detection model includes:
acquiring a training set and constructing an initial training model, wherein the training set comprises a plurality of groups of power transmission line images and labeled images which correspond to the power transmission line images one by one;
and training the initial training model by adopting the training set to obtain a completely-trained line detection model.
In this embodiment, the power transmission line image used for training may include an abnormal object or have an abnormal condition, and the annotation image corresponding to the abnormal object may be obtained in a manual annotation and/or automatic annotation manner. For example, an abnormal object or an abnormal state in the image can be identified by a worker according to experience, then the image is marked, and then the marked image and the power transmission line image are input into an initial training model for training, so that a completely trained line detection model is obtained.
In some embodiments, the line detection model is a machine learning model or a deep learning model, and the initial training model is also a machine learning model or a deep learning model.

and carrying out sparsification on the convolution kernel of the initial training model.
Specifically, the sparsity of W can be reduced by adding an L0 paradigm about W to a loss function of the network, but the L0 paradigm causes an N-P problem which is a difficult-to-optimize solution problem, so an author trains the sparsized network from another idea. The algorithm flow is as follows:
training the network s1 normally, then Ok (W) indicates that the largest k values in W are selected, the rest values are set to be 0, suppp (W, k) indicates the sequence number of the largest k values in W, training s2 turns is continued, only W which is not 0 is updated, then W which is previously set to be 0 is released for updating, and training s1 turns is continued, and the steps are repeated until the training is finished. The method is also a method for inducing parameters, training and clipping are carried out, the values which are considered to be unimportant are clipped, and then important parameters which are mistakenly clipped are restored through a restore process.
In some embodiments, after the line detection model identifies the power transmission line image, a line detection result is output, when there is no abnormality in the image, the line detection result is a normal result, and at this time, the output image is the power transmission line image without a label, when there is an abnormal condition in the image, the line detection result is an abnormal result, and at this time, the output image is the power transmission line image labeled with abnormal information, where the abnormal information includes, but is not limited to, the presence of a foreign object on the line, the presence of an abnormal condition (e.g., a disaster such as fire, smoke, etc.) near the line, and the presence of an abnormality (e.g., a broken wire, etc.) in the line.
In some embodiments, when there is an abnormality on the line, directly sending out alarm information to prompt a worker, specifically, the sending out corresponding alarm information includes:
and outputting voice prompt information containing abnormal information according to the power transmission line image marked with the abnormal information.
In this embodiment, the staff is reminded to the mode that directly utilizes voice prompt, voice prompt's mode has the multiple, for example, when this transmission line inspection device contains the voice broadcast function, can directly utilize this transmission line inspection device output to contain the voice prompt information of abnormal information, of course, in order to avoid the staff can't in time receive information, can also send voice prompt information to interactive equipment through the network, utilize interactive equipment output to contain the voice prompt information of abnormal information, in order to reach effective suggestion staff's purpose.
