For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] The following is combined with Figures 1 to 8 The technical solution of the present invention is further illustrated by specific implementation methods.

[0056] An intelligent grounding wire monitoring and management system, comprising: a grounding wire management background 100, a grounding wire status collector 200 and a hooking end detection device 300;

[0057] The hook end detection device 300 is installed at the hook end 92 of the grounding wire 90, the hook end 92 is used to connect with the conductor to be grounded 60, the hook end detection device 300 is used to detect and obtain the status information of the hook end 92, and the hook end detection device 300 is connected to the grounding wire status collector 200 for communication;

[0058] The ground wire status collector 200 is installed at the grounding end 91 of the grounding wire 90, and the grounding end 91 is used to connect with the grounding pile 40. The grounding pile 40 is provided with a grounding wire pile identity component. When the grounding end 91 is plugged into the grounding pile 40, the ground wire status collector 200 identifies and obtains the information of the grounding wire pile identity component.

[0059] The grounding wire management background 100 is in communication connection with the grounding wire status collector 200 , and the grounding wire management background 100 is used to manage and control the grounding wire 90 and prevent power errors.

[0060] The present invention provides an intelligent grounding wire monitoring and management system, which solves the reliability problem of the acquisition of the connection / removal status of the grounding wire 90 through the coordinated work of the grounding wire management background 100, the grounding wire status collector 200, and the hanging end detection device 300. The hanging end detection device 300 is installed on the hanging end 92 of the grounding wire, responsible for detecting the status information of the hanging end 92 and transmitting it to the grounding wire status collector 200; the grounding wire status collector 200 is installed on the grounding end 91 of the grounding wire, used to identify the identity information of the grounding pile 40; the grounding wire management background 100 is responsible for overall status monitoring and management to ensure the correct connection and removal operation of the grounding wire 90. Through this design, the status of the grounding wire 90 can be monitored in real time to ensure that the connection and removal of the grounding wire 90 comply with safety regulations, thereby preventing or eliminating the occurrence of power safety accidents.

[0061] By installing the hook-end detection device 300 at the hook-end 92 of the grounding wire 90, the connection status between the hook-end and the conductor to be grounded 60 can be detected in real time and accurately, including the confirmation of the conductive properties and the feedback of the hook-up and removal status, thereby improving the reliability of the acquisition of the hook-up / removal status of the grounding wire and effectively avoiding the problem of missed hooking or missed removal caused by inaccurate pressure or micro-motion detection in traditional methods. Furthermore, one grounding wire 90 is equipped with three hook-end detection devices 300, which are respectively used for the detection of the hook-up status of the three phases of line A / B / C. For some high-voltage grounding wires, such as those above 500kV, which are generally split-phase grounding wires, one grounding wire can be equipped with one hook-end detection device 300.

[0062] The ground wire status collector 200 is directly installed on the grounding terminal 91 of the grounding wire 90. This design enables the system to easily adapt and transform the existing grounding wire 90 without large-scale equipment replacement, reducing the cost and time of transformation. Specifically, the ground wire status collector 200 has a built-in positioning module, an upward communication module, and a downward communication module, which can realize the determination of the hanging and disassembly position of the grounding terminal 91 and the hanging terminal 92 of the grounding wire, the monitoring and sending of the hanging and disassembly status, and the local alarm function. The hanging terminal 92 and the ground wire status collector 200 are connected by the grounding wire, which is a fixed combination relationship. When the grounding terminal 91 is hung with the grounding pile 40, the ground wire status collector 200 identifies the grounding pile identity component 41 information and stores it. When the ground wire status collector 200 receives the hanging status of the hanging terminal 92, it synchronously sends the position information of the grounding wire 90 (grounding pile 40), the hanging status information of the grounding terminal 91, and the hanging status information of the hanging terminal 92 to the grounding wire management background 100. This enables the intelligent grounding wire monitoring and management system of the present invention to not only monitor the state of the hooking end 92, but also identify the information of the grounding wire pile identity component 41 on the grounding pile 40 through the grounding wire state collector 200, thereby realizing dual monitoring and verification of the hooking end 92 and the grounding end 91. This dual protection mechanism greatly enhances the anti-error effect of the grounding wire 90 operation, and effectively prevents safety accidents caused by errors in a single link.

[0063] As the control center of the entire system, the grounding wire management background 100 can centrally control all grounding wires 90 and their operating status, realize remote monitoring, data recording and analysis, alarm prompts and other functions, and improve the management level and efficiency of power safety production. Specifically, the grounding wire management background 100 receives the status information of the grounding wire 90 through the wireless network; grounding wire ledger management, including grounding wire numbering, grounding wire positioning coordinates, grounding pile management, map positioning display, electrical wiring diagram, grounding wire hanging end 92 hanging status, grounding wire grounding end 91 hanging status, grounding wire in the warehouse and out of the warehouse and other status displays. Through real-time monitoring and precise management, the system can promptly detect and correct violations in the operation of the grounding wire 90, significantly reduce the risk of personal injury and equipment damage accidents caused by human negligence, and provide a more solid safety guarantee for power production.

[0064] In summary, the intelligent grounding wire monitoring and management system significantly improves the reliability and accuracy of grounding wire status monitoring through technological innovation and optimized design, enhances the compatibility and flexibility of the system, and promotes the improvement of the level of power error prevention management, which is of great significance for ensuring the safety of power production.

[0065] Furthermore, the grounding terminal 91 is provided with a locking state sensing part 911, and the grounding post 40 is provided with a locking triggering part 42. When the grounding terminal 91 and the grounding post 40 are hooked and locked, the locking triggering part 42 senses and triggers the locking state sensing part 911 to trigger the locking state S11. When the grounding terminal 91 and the grounding post 40 are unlocked, the locking state S11 is cancelled.

[0066] The status information of the locking status sensing unit 911 is transmitted to the ground line status collector 200 .

[0067] By setting a locking state sensing part 911 on the grounding terminal 91 and cooperating with the locking triggering part 42 on the grounding post 40, the locking state S11 will be triggered only when the grounding terminal 91 and the grounding post 40 are correctly and firmly hooked and locked. This ensures that the grounding wire 90 will not cause safety hazards due to looseness or incomplete connection during the hooking process, further improving the safety of the grounding operation. The triggering of the locking state is not only a confirmation of a physical connection, but also a verification of the stability and reliability of the connection. By receiving the status information of the locking state sensing part 911 through the ground wire status collector 200, the system can more accurately determine whether the grounding wire has been correctly hooked, reducing errors caused by human misjudgment or negligence.

[0068] Furthermore, the design of the locking state sensing unit 911 and the locking trigger unit 42 can be used as a standardized interface or module, which can be easily compatible and expanded with other types of grounding wires or grounding piles in the future, thereby improving the flexibility and upgradeability of the system. Specifically, the locking state sensing unit 911 can be set as an intelligent module with a code reading function, and the locking trigger unit 42 is designed as a code chip with RFID. When the intelligent module can identify the code chip with RFID, the corresponding information can be read from the code chip with RFID, and the information data can be identified and transmitted to the ground wire state collector 200. The design of this locking state can prevent unauthorized or erroneous grounding wire operations to a certain extent. Only when the correct grounding terminal is matched with the corresponding grounding pile can the locking state be triggered, thereby avoiding power safety accidents caused by misconnection or misoperation. The automatic sensing and transmission of the locking state makes the entire intelligent grounding wire monitoring and management system more intelligent. The system can automatically detect and record the connection state of the grounding wire without manual intervention, thereby improving work efficiency and accuracy.

[0069] Furthermore, the locking state sensing portion 911 is disposed in a concave cavity of the grounding end 91 , and the locking triggering portion 42 is disposed in a convex column of the grounding post 40 , and the convex column is cooperatively connected with the concave cavity.

[0070] By arranging the locking state sensing part 911 in the concave cavity of the grounding terminal 91, and arranging the locking trigger part 42 in the convex column of the grounding post 40, and by the matching connection between the convex column and the concave cavity, it is possible to ensure that the connection between the grounding wire 90 and the grounding post 40 is more accurate and stable. This can reduce the potential safety hazards caused by loose connection or misalignment.

[0071] When the grounding wire 90 is correctly connected to the grounding post 40, the locking state sensing unit 911 and the locking triggering unit 42 can instantly sense the connection state, thereby triggering the locking state S11 to achieve accurate monitoring or alarm mechanism. This helps to timely discover and solve problems in the connection and improve the safety of the grounding operation.

[0072] Further, the hook end detection device 300 includes a sensing component 310 and an electric control component 320, and the sensing component 310 and the electric control component 320 are electrically connected;

[0073] The induction component 310 is installed on the moving contact 921 of the hanging end 92. The induction component 310 moves with the moving contact 921 and clamps or releases the conductor to be grounded 60.

[0074] The sensing component 310 includes a first state sensing module 311 and a second state sensing module 312. The first state sensing module 311 is used to determine whether the conductor to be grounded 60 is a conductor. When the first state sensing module 311 forms a conducting circuit with the conductor to be grounded 60, the first state S21 of the hooking is triggered. The second state sensing module 312 is used to determine whether the hooking end 92 clamps the conductor to be grounded 60. When the second state sensing module 312 senses, the second state S22 of the hooking is triggered.

[0075] The electric control component 320 supplies power to the sensing component 310 . The electric control component 320 receives status information of the sensing component 310 and transmits the status information to the ground line status collector 200 .

[0076] Through the first state sensing module 311 in the sensing component 310, the system can accurately determine whether the conductor 60 to be grounded is a conductor, thereby avoiding mistakenly using a non-conductor as a grounding object. At the same time, the second state sensing module 312 ensures that the hooking end 92 has firmly clamped the conductor 60 to be grounded. Only when these two conditions are met can the effectiveness and safety of the hooking operation be confirmed.

[0077] like Figures 1 to 3As shown, the hanging end 92 is hung on the conductor to be grounded 60; in the prior art, the hanging end is usually a hook-type clip or an F-type clip as shown in the figure, and these hanging ends all include a static contact 922 and a moving contact 921, and the conductor to be grounded 60 is located between the static contact 922 and the moving contact 921. During the hanging process of the hanging end 92, the grounding rod of the grounding wire 90 is twisted to drive the moving contact 921 to approach the static contact 922, so that the hanging end 92 clamps the conductor to be grounded 60, thereby preventing the grounding wire 90 from being separated from the grounding conductor during the maintenance process, thereby preventing the maintenance personnel from causing a safety accident. Therefore, in this solution, the sensing component 310 of the hooking end detection device 300 is installed on the moving contact 921 at the lower part of the hooking end 92. When the sensing component 310 gradually approaches the static contact 922 with the moving contact 921 to clamp the grounding conductor 60, the first state sensing module 311 can accurately determine whether the grounding conductor 60 is a conductor, thereby avoiding mistakenly using a non-conductor as a grounding object; the second state sensing module 312 can ensure that the hooking end 92 has firmly clamped the grounding conductor 60. Only when these two conditions are met can the effectiveness and safety of the hooking operation be confirmed. This enables the system to automatically complete the detection and confirmation of the hooking state without manual intervention, thereby improving work efficiency and accuracy. At the same time, the electric control component 320 provides stable and reliable power supply for the sensing component 310, and receives and processes status information in real time, further improving the intelligence level of the system.

[0078] Further, the sensing component 310 is disposed at the moving contact 921 at the lower part of the hook end 92, rather than at the top of the hook end 92, so that the hook end detection device 300 can be better compatible with the bare wire ( Figure 1 shown) and mounting ring ( Figure 2 As shown in the figure, there are two types of hanging objects (if the sensing component 310 is set at the top of the hanging end 92, it cannot be adapted to the hanging ring), which means that in different application scenarios, there is no need to replace different types of monitoring equipment, thereby improving the applicability and flexibility of the system.

[0079] Through dual state sensing (conductivity judgment and clamping state judgment), the system can more comprehensively evaluate the safety and reliability of the grounding wire 90 hooking operation, which helps prevent power safety accidents caused by loose or incorrect hooking, and provides a more solid safety guarantee for power production. The design of the sensing component 310 and the electric control component 320 has a certain degree of versatility and configurability, and can adapt to different types of grounded conductors 60 and hooking requirements. In the future, with the continuous development of power equipment and technology, the system can adapt to new application scenarios and needs by replacing or upgrading the sensing component and the electric control component.

[0080] Furthermore, the first state sensing module 311 is a conductor block, and the conductor block covers a partial area of ​​the moving contact 921, and the partial area is an area where the moving contact 921 and the static contact 922 are opposite. When the conductor block contacts the conductor to be grounded 60 to form a conducting circuit, the first hooking state S21 is triggered;

[0081] The second state sensing module 312 includes a shell 3121, a stroke slider 3122, a magnet 3123 and a reed switch. The magnet 3123 is installed on the stroke slider 3122, and the reed switch is installed on the shell 3121 and corresponds to the magnet 3123. The stroke slider 3122 is movably arranged in the shell 3121, and the top of the stroke slider 3122 protrudes from the shell 3121. When the moving contact 921 approaches the static contact 922 to clamp the conductor to be grounded 60, the conductor to be grounded 60 compresses the stroke slider 3122 protruding from the shell 3121, so that the magnet 3123 is close to the reed switch, triggering the second hooking state S22.

[0082] The first state sensing module 311 adopts a conductor block design, which can directly contact the conductor to be grounded 60 and form a conductive circuit. This enables the system to quickly and accurately determine the conductivity of the conductor to be grounded 60, and once contacted, it triggers the first hanging state S21, thereby improving the sensitivity of detection. The second state sensing module 312 uses the interaction between the magnet 3123 and the reed switch to determine whether the hanging end 92 clamps the conductor to be grounded 60. When the travel slider 3122 is compressed by the conductor to be grounded 60, causing the magnet 3123 to approach the reed switch, the reed switch is triggered, thereby accurately determining the clamping state of the hanging end 92. This mechanical triggering method is stable and reliable, and is not easily affected by external interference. Through the joint action of these two state sensing modules, the hanging state of the grounding wire hanging end 92 can be effectively monitored to ensure the safety and reliability of the grounding operation.

[0083] To further illustrate, for the connection of the three-phase line, the connection status of each connection terminal 92 (connection terminal detection device 300) is updated to the ground wire status collector 200 respectively. When the three connection terminals 92 have updated the connection status, the ground wire status collector 200 uploads the status of the ground wire 90 to the ground wire management background 100 to ensure the timeliness of the data status of the ground wire 90 in the ground wire management background 100.

[0084] Preferably, the ground wire hanging end detection device 300 is battery-powered, and can be used with wireless charging or non-rechargeable batteries. The ground wire hanging end detection device 300 has a built-in short-range wireless communication module (including 2.4G, Bluetooth, infrared, star flash, etc.), and can also lead out wired (such as RS485) to communicate with the ground wire status collector 200; when Bluetooth communication is used, broadcast is applied, and the hanging status of the hanging end 92 can be realized by broadcasting, without the need for Bluetooth pairing, thereby achieving ultra-low power consumption operation of the device.

[0085] Furthermore, the intelligent grounding wire monitoring and management system further includes a mobile intelligent terminal 500, the ground wire status collector 200 includes a ground wire identity component, and the mobile intelligent terminal 500 is used to identify the ground wire identity component and the grounding wire pile identity component;

[0086] After the mobile smart terminal 500 identifies the ground wire identity component, the mobile smart terminal 500 is task-bound with the ground wire status collector 200 , and the ground wire status collector 200 is communicatively connected with the ground wire management backend 100 through the mobile smart terminal 500 .

[0087] The mobile intelligent terminal 500 (such as a smart phone, tablet computer, etc.) is the main interactive device of the user, making the system operation more flexible and portable. The user can check the connection status of the grounding wire, receive alarm information or perform task management through the mobile intelligent terminal 500 anytime and anywhere without being fixed in front of a workstation or computer.

[0088] The mobile smart terminal 500 identifies the ground wire identity component and the ground wire pile identity component 41, thereby realizing rapid positioning and identification of the ground wire 90 and the ground pile 40. This helps the user to quickly and accurately understand the status and progress of the current work task, thereby improving the efficiency of task management.

[0089] The ground wire status collector 200 communicates with the ground wire management background 100 through the mobile smart terminal 500. This indirect communication method can reduce the complexity and cost of direct communication between the ground wire status collector 200 and the background. At the same time, the mobile smart terminal 500, as an intermediary, can provide a more stable communication connection and better data transmission effect.

[0090] By binding the tasks of the mobile smart terminal 500 and the ground wire status collector 200, the system can more accurately control and manage the usage and status of the ground wire. At the same time, the mobile smart terminal 500 can also provide identity authentication and permission management functions to ensure that only authorized users can access and operate the system, thereby improving the security and manageability of the system.

[0091] A working method of an intelligent grounding wire monitoring and management system includes the following steps for the connection process of the grounding wire 90:

[0092] Step A1, simulated hooking: the grounding wire management background 100 simulates the hooking of the grounding wire 90, and judges each operation according to the existing status data of the grounding wire, grounding pile, etc. If the operation is correct and complies with the "five-prevention" operation rules, the grounding wire management background 100 dispatches a task to the mobile smart terminal 500 and allows the next operation;

[0093] By simulating the hooking steps (step A1), the system can prejudge and verify the operation before the actual hooking operation to ensure that the operation complies with the "five prevention" operation rules (i.e., preventing the circuit breaker from being opened or closed by mistake, preventing the disconnector from being pulled or closed with load, preventing the grounding wire from being hooked or the grounding knife switch being closed with power on, preventing the circuit breaker or disconnector from being closed with the grounding wire or the grounding knife switch being closed, and preventing the circuit breaker or disconnector from being mistakenly entered into the live compartment). This greatly reduces the risk of safety accidents caused by improper operation.

[0094] Step A2, taking the ground wire: the mobile intelligent terminal 500 identifies the taken ground wire 90 and binds the maintenance task to the ground wire status collector 200;

[0095] After the operator takes the grounding wire 90 from the library, he identifies the grounding wire status collector 200 through the mobile smart terminal 500 to obtain the identity information of the grounding wire, and binds the maintenance task to the grounding wire status collector 200. This step ensures that a clear association is established between each grounding wire 90 and its corresponding maintenance task, which facilitates subsequent status tracking and management.

[0096] Step A3, hooking the grounding wire: the operator brings the grounding wire 90 to the maintenance site, the grounding end 91 of the grounding wire 90 is locked with the grounding stake 40, and the hooking end 92 of the grounding wire 90 is hooked with the conductor to be grounded 60;

[0097] Step A4, status feedback: the identity information of the grounding pile 40, the status information of the grounding terminal 91, the status information of the hooking terminal 92, etc. are fed back to the grounding management background 100 via the grounding status collector 200 and the mobile smart terminal 500;

[0098] During the process of connecting the ground wire (step A3) and status feedback (step A4), the system can collect and transmit the status information of key components such as the grounding pile 40, the grounding terminal 91, and the connecting terminal 92 in real time. This information is fed back to the ground wire management background 100 in a timely manner through the ground wire status collector 200 and the mobile smart terminal 500, so that the management personnel can grasp the connection status and on-site conditions of the ground wire in real time.

[0099] Furthermore, for the process of connecting the ground wire 90, the step A3 further includes the following steps:

[0100] Step A3-1, confirming the grounding pile information: the mobile smart terminal 500 identifies the grounding pile identity component 41 and confirms that the grounding pile 40 is the task target;

[0101] By identifying and confirming the information of the grounding pile 40 through the mobile smart terminal 500, the mobile smart terminal 500 can identify and confirm whether the grounding pile 40 is the target of the current task, thereby avoiding operational errors caused by selecting the wrong grounding pile 40 and improving the accuracy of the operation.

[0102] Step A3-2, the grounding wire and the grounding post are hooked and locked: by inserting the grounding end 91 of the grounding wire 90 into the grounding post 40, the locking state S11 is triggered and fed back to the grounding wire state collector 200;

[0103] The hooking and locking of the grounding wire 90 and the grounding post 40 is a key step to ensure grounding safety. By inserting the grounding end 91 of the grounding wire 90 into the grounding post 40 and triggering the locking state S11, the system can monitor the connection state between the grounding post 40 and the grounding wire 90 in real time. This mechanical locking design increases the stability and reliability of the connection and prevents the grounding wire from accidentally falling off or loosening.

[0104] Step A3-3, the grounding wire is hung on the conductor: by hanging the hanging end 92 of the grounding wire 90 on the conductor to be grounded 60, and clamping the conductor to be grounded 60 by the hanging end 92, the hanging end detection device 300 triggers the first hanging state S21 and the second hanging state S22 respectively, and the hanging end detection device 300 feeds back the status information to the ground wire status collector 200.

[0105] The hooking process of the grounding wire 90 and the conductor to be grounded 60 realizes dual state detection through the hooking end detection device 300. The first hooking state S21 detects the conductivity through the contact between the conductor block and the conductor to be grounded 60, while the second hooking state S22 detects whether the hooking end 92 clamps the conductor to be grounded 60 through the interaction between the magnet 3123 and the reed switch. This dual detection mechanism improves the accuracy and reliability of the hooking state detection.

[0106] The status information in each step can be fed back to the ground wire status collector 200 in real time, and transmitted to the ground wire management background 100 through the mobile intelligent terminal 500. This real-time feedback mechanism enables the system to respond quickly to operational changes, update status information in a timely manner, and improve the response speed and efficiency of the system. Each step is designed with a corresponding status detection and feedback mechanism to ensure that the system can monitor and record the hooking status of the ground wire in real time. This comprehensive status monitoring and recording function improves the reliability and maintainability of the system.

[0107] A working method of an intelligent grounding wire monitoring and management system includes the following steps for the grounding wire removal process:

[0108] Similar to the mounting process, the removal process includes step B1, simulated removal: the ground wire management background 100 simulates the removal of the ground wire, and judges each operation according to the existing status data of the ground wire, grounding pile, etc. If the operation is correct and complies with the "five-prevention" operation rules, the ground wire management background 100 dispatches a task to the mobile smart terminal 500 and allows the next operation to proceed;

[0109] Through this step, the grounding wire management background 100 can simulate and verify the removal operation based on the existing status data of the grounding wire 90, the grounding pile 40, etc., to ensure that the operation complies with the "five-prevention" operation rules. This greatly reduces the risk of safety accidents caused by improper operation and improves the safety of the overall operation.

[0110] Step B2, removing the grounding wire: removing the connection between the hanging end 92 and the conductor and the locking between the grounding end 91 and the grounding stake 40;

[0111] The connection between the hooking end 92 and the conductor and the locking between the grounding end 91 and the grounding post 40 are removed in sequence. The operator first completes the removal of the hooking end 92. When the hooking end 92 is removed, it will be determined whether the hooking first state S21 signal and the hooking second state S22 signal exist. If the hooking second state S22 signal has been revoked but the hooking first state S21 signal still exists, the hooking end detection device 300 will issue an on-site alarm and transmit the state to the ground wire state collector 200, and further transmit it to the ground wire management background 100 for alarm. If the ground wire state collector 200 detects the hooking signal of any hooking end (hooking end detection device 300), but the locking state S11 signal of the grounding end 91 does not exist, the ground wire management background 100 determines it as a wrong operation and issues an alarm. This clear removal sequence guidance helps operators to follow the correct steps to avoid equipment damage or safety hazards caused by the wrong removal sequence.

[0112] Step B3, status feedback: the status information of the grounding terminal 91 and the status information of the hooking terminal 92 are fed back to the grounding wire management background 100 via the ground wire status collector 200 and the mobile intelligent terminal 500.

[0113] During the removal process, the system can collect and transmit the status information of the grounding terminal 91 and the hooking terminal 92 in real time. This information is fed back to the grounding management background 100 in a timely manner through the grounding status collector 200 and the mobile intelligent terminal 500, so that the management personnel can grasp the removal status and on-site conditions of the grounding wire in real time. This real-time status monitoring function helps to discover and handle abnormal situations in a timely manner, ensuring the safe and smooth progress of the removal operation.

[0114] By recording the removal process and status information of the grounding wire, the system can establish complete operation records and historical data. These data provide important basis for subsequent troubleshooting, responsibility tracing and performance evaluation, and enhance the traceability and manageability of the system.

[0115] Furthermore, for the removal process of the ground wire 90, the step B2 further includes the following steps:

[0116] Step B2-1, removing the hanging end: removing the hanging end 92 from the conductor, releasing the first hanging state S21 and the second hanging state S22 of the hanging end detection device 300 respectively, and the release information is fed back to the ground wire state collector 200;

[0117] Step B2 - 2 , removing the grounding terminal: unlocking and removing the grounding terminal 91 from the grounding post 40 , releasing the locking state S11 , and feeding back the release information to the ground line state collector 200 .

[0118] Through the clear division of steps B2-1 and B2-2, the operator can more clearly understand each step of the removal process. The release of the first hooking state S21 and the second hooking state S22 of the hooking end detection device 300, as well as the unlocking and removal of the grounding end 91 from the grounding post 40, are accompanied by corresponding status feedback. This instant feedback mechanism ensures that the operator can accurately judge whether each step of the operation is successfully completed, thereby improving the accuracy and reliability of the operation.

[0119] The detailed steps emphasize the order of removing the hook terminal 92 first and then the grounding terminal 91, which complies with the safety operation regulations and helps to avoid potential safety hazards during the removal process. The correct removal sequence can ensure that the grounding wire remains stable during the removal process, preventing equipment damage or personal injury caused by improper operation.

[0120] During the removal process, the system not only monitors the status changes of the grounding terminal 91 and the hooking terminal 92, but also collects and feeds back the status information in real time through the ground wire status collector 200. This comprehensive status monitoring function enables the management personnel to grasp the removal progress and status of the ground wire in real time, providing strong support for subsequent maintenance and management.
