the electric field strength detection module 110 is configured to detect an electric field strength near the tool to be worked and send a detection result to the control module 140; the first detection module 120 is used for detecting angle information and distance information between a tool to be operated and the power transmission line, the second detection module 130 is used for detecting distance information between the tool to be operated and the power transmission line, and the control module 140 is used for controlling the first detection module 120 and/or the second detection module 130 to be turned on according to the detection result of the electric field strength detection module 110.
The electric field strength detection module 110 may be configured to determine whether there is a power transmission line near the tool to be operated, and particularly, when the tool to be operated needs to be operated or constructed at night, the human eye cannot distinguish whether there is a power transmission line near the tool to be operated, and the device may detect whether there is a power transmission line near the tool to be operated, so as to effectively avoid electric shock, line fault, and the like. The first detection module 120 is configured to detect angle information and distance information between the tool to be operated and the power transmission line, where the angle information includes an included angle formed by a connection line between a left boundary of the tool to be operated and the power transmission line and a connection line between a right boundary of the tool to be operated and the power transmission line, an approximate range between the tool to be operated and the power transmission line can be determined according to the angle information, and a distance between the tool to be operated and the power transmission line can be roughly determined according to the distance information. The control module 140 may be a single chip, a PLC controller, or the like. The first wireless communication module 150 may be a bluetooth module, a WIFI module, or the like.
Optionally, the control module 140 is configured to control the first detecting module 120 to turn on according to the detection result of the electric field strength detecting module 110, and includes:
the control module 140 is configured to control the first detecting module 120 to turn on when the electric field strength detecting module 110 detects that the electric field strength in the vicinity of the work tool is greater than a first preset electric field strength.

The second preset distance may be an early warning distance from the tool to be operated to the power transmission line, and may be, for example, a warning distance of 3m or 2 m. When the first detection module 120 detects that the distance between the tool to be operated and the power transmission line is greater than the second preset distance, that is, greater than the warning distance, it indicates that the distance between the tool to be operated and the power transmission line is a safe operation distance. When the first detecting module 120 detects that the distance between the tool to be operated and the power line is smaller than the second preset distance, it indicates that the distance between the tool to be operated and the power line has entered the warning distance, and if the distance is a dangerous operation distance (i.e., the first preset distance), the second detecting module 130 needs to be turned on for further detection.

When the electric field intensity near the tool to be detected reaches a first preset electric field intensity, the control module 140 controls the first detection module 120 to be started, and after the first detection module 120 is started, the control module detects angle information and distance information of the tool to be operated and the power transmission line so as to preliminarily determine the positions of the tool to be operated and the power transmission line. If the distance detected by the first detecting module 120 is greater than the second preset distance, it can be determined that the tool to be worked is working within the safe distance, and the control module 140 does not need to turn on the second detecting module 130. If the distance detected by the first detection module 120 is less than the second preset distance, it may be roughly determined that the tool to be operated enters the warning distance, that is, the tool may operate within the unsafe distance, and further, in order to more accurately determine whether the distance is the safe operation distance, the control module 140 controls to turn on the second detection module 130, and after the second detection module 130 is turned on, the control module detects a more precise distance between the tool to be operated and the power transmission line.

In the technical solution of this embodiment, the power transmission line positioning apparatus is implemented as follows: assuming that a tool to be operated works below a power transmission line, the detection system 100 of the positioning device is fixedly installed at the end of the tool to be operated, for example, the tool to be operated is a tool for cleaning a tree obstacle below the power transmission line, the detection system 100 is fixedly installed at the tool, and during the process of cleaning the tree obstacle by the tool, the electric field intensity near the tool to be operated is detected by the electric field intensity detection module 110 to determine whether the power transmission line exists near the tool to be operated. When the electric field intensity near the tool to be detected reaches a first preset electric field intensity, the control module 140 controls the first detection module 120 to be started, and after the first detection module 120 is started, the control module detects angle information and distance information of the tool to be operated and the power transmission line so as to preliminarily determine the positions of the tool to be operated and the power transmission line. If the distance detected by the first detection module 120 is greater than the second preset distance, it may be determined that the distance between the tool to be operated and the power transmission line is a safe operation distance, the control module 140 sends information capable of safe operation to the display module 210 through the first wireless communication module 150 and the second wireless communication module 230, the display module 210 receives the signal and displays the information to prompt an operator or a related worker that the tool to be operated can operate, and at this time, the control module 140 does not need to start the second detection module 130. If the distance detected by the first detection module 120 is less than the second preset distance, it may be roughly determined that the tool to be worked enters the warning distance, that is, it may work within the unsafe distance, further, in order to more accurately determine whether the distance is the safe working distance, the control module 140 controls to turn on the second detection module 130, detect the more precise distance between the tool to be worked and the power transmission line after the second detection module 130 is turned on, if the detected distance is less than the first preset distance, the control module generates an alarm signal and sends the alarm signal to the display module 210 and the acousto-optic alarm module 220 through the first wireless communication system 150 and the second wireless communication system 230, the display module 210 displays the alarm signal, and the acousto-optic alarm module 220 sends out an alarm message to prompt the relevant worker that the tool to be worked in the area cannot work. Therefore, the electric field intensity near the tool to be worked is firstly detected by the electric field intensity detection module to judge whether the power transmission line exists near the tool to be worked (especially, when construction is carried out at night, whether the power transmission line exists above the tool to be worked can not be seen), when the existence of the power transmission line is detected, the first detection module 120 detects whether the distance between the tool to be operated and the power transmission line is less than a second preset distance (i.e., the early warning distance), and if the distance is greater than the second preset distance, the display system can prompt safe operation directly, if the distance is less than the second preset distance, the second detection module 130 further detects whether the distance is less than the first preset distance (i.e. dangerous operation distance), if the distance is greater than the first preset distance, and directly prompting reluctant safe operation through the display system, and if the distance is less than the second preset distance, performing alarm display through the display system. Whether the distance between the tool to be operated and the power transmission line is the safe operation distance can be judged through the device from this, and corresponding warning signal is generated in order to indicate operating personnel, harm and loss that the easy erroneous judgement of manpower inspection brought can be reduced, the automation and the intellectuality of detection are improved to ensure to treat that the tool to be operated can be in the safe distance.
