It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for positioning the fault underground cable can be applied to the application environment shown in figure 1. Wherein the underground cable collection system 102 is in communication with the server 104 via a network. The underground cable collecting system 102 can collect current environment data and current operation data of the underground cable and send the current environment data and the current operation data to the server 104, the server 104 judges whether the underground cable is in fault according to the current environment data and the current operation data, if the underground cable is in fault, a rough position of the underground cable is obtained, and then a corresponding target underground path diagram is obtained according to the rough position, so that the server 104 extracts a target cable well closest to the rough position from the target underground cable path diagram, then the distance between the cable well position and the rough position of the target cable well is calculated, whether the inspection by a robot or the detection by an underground cable endoscope is carried out is determined according to the distance, so as to obtain the precise position, when the distance between the cable well position and the rough position is larger than a threshold value, a patrol command is sent to the robot to enable the robot to acquire the precise position of the faulty underground cable according to the rough position, otherwise, the patrol is realized through an underground cable endoscope. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.

In order to ensure the data queryability, the underground cable acquisition system and the geographical position of the underground cable are sent to the server together when sending data, and optionally, the label of the underground cable can be preset, and the corresponding relation between the label and the position of the underground cable is established, so that when the service receives the data sent by the underground cable acquisition system with a certain label, the geographical position information corresponding to the underground cable can be queried according to the label.
Specifically, the server can judge whether the underground cable is failed according to the failure judgment model. The fault judgment model is a training model which is generated according to historical data and used for judging whether the underground cable has faults or not, the input of the fault judgment model is current environment data and current operation data, and the output of the fault judgment model is the probability of the faults of the underground cable. And the server inputs the current environment data and the current operation data into a fault judgment model which is trained in advance to obtain a fault judgment result, the fault judgment result is compared with a predetermined threshold value, if the fault judgment result is larger than the predetermined threshold value, the underground cable is judged to have a fault, and otherwise, the underground cable does not have the fault. Optionally, when the fault judgment model processes the current environment data and the current operation data, the current environment data may be compared with the environment data of the historical fault during the training of the model, the current operation data may be compared with the operation data of the historical fault, so as to obtain the similarity, and then all the similarities are integrated to obtain the fault judgment result.

In one embodiment, when the distance between the cable well location and the rough location is less than or equal to a threshold value, the precise location of the faulty underground cable is obtained through an underground cable endoscope.
Specifically, when the server determines that the distance between the cable well position and the rough position is smaller than or equal to the threshold value, the server can acquire the accurate position of the underground cable with the fault through the underground cable endoscope, namely, the underground cable endoscope extends into the cable trench to perform image shooting, and then determine where the underground cable has the fault according to the shot image, namely, acquire the accurate position of the underground cable with the fault.
In one embodiment, the obtaining the target underground cable routing corresponding to the rough location comprises: acquiring a street identifier and an urban underground cable path diagram corresponding to the rough position; and extracting an area corresponding to the street sign from the urban underground cable path map as a target underground cable path map.
Specifically, the server may obtain an underground cable routing graph of a corresponding city according to the rough location, and then determine a street identifier corresponding to the rough location, so as to extract a target underground cable routing graph from the underground cable routing graph of the city according to the street identifier, for example, taking the rough location as a central point, taking a street region corresponding to the street identifier as a target region, and extracting a region having a preset distance from the rough location as the target underground cable routing graph.

Therefore, the server can calculate the distance between the first coordinate and the second coordinate according to the trend of the underground cable in the target underground cable path diagram, and then obtains a corresponding cable well with the minimum distance as a target cable well.

Specifically, after receiving the inspection instruction, the robot acquires an image, and determines whether the underground cable corresponding to the rough position has a fault according to the acquired image, specifically, the server identifies the image acquired by the robot to determine whether the underground cable has a fault or not, which may be determining the similarity between the image and a standard image, for example, first determining that the image is matched with an image with a standard fault to obtain a first similarity, and matching the image with a standard fault to obtain a second similarity, determining whether the first similarity is smaller than a first preset value, if so, indicating that a fault may exist, and then determining whether the second similarity is larger than a second preset value, and if so, indicating that a fault necessarily exists. When a fault exists, calculating the distance between the robot and the target cable well so as to determine the accurate position of the fault underground cable through the distance between the robot and the target cable well.
