[0002] In power systems, grounding wires are crucial for ensuring worker safety. Traditional grounding wires, primarily simple mechanical structures, present numerous problems in practical use. For instance, it's impossible to determine in real-time whether the grounding rod is properly inserted, leading to poor grounding and increasing the risk of accidents. During installation, it's difficult to detect issues like loose connections or whether the connected object is a conductor, problems that are hard to accurately identify manually. Furthermore, there's a lack of effective early warning mechanisms when personnel approach hazardous areas. Additionally, existing grounding wire devices are poorly adaptable to different grounding rod sizes for various work scenarios, exhibiting limited versatility.

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0016] Please see Figure 1-6 This invention provides the following technical solution: an intelligent grounding wire monitoring device and its usage method, comprising a communication main module 7 and an intelligent grounding rod 18. The communication main module 7 includes a device communication status indicator 8, an abnormality indicator 9, a charging indicator 10, a main module power button 11, a human body induction switch 12, a charging port 13, an abnormal information broadcast button 14, and a device operation status indicator 15. The intelligent grounding rod 18 is equipped with a conductor detection module 16 and a positioning detection module 17. The conductor detection module 16 and the positioning detection module 17 are used to determine the attributes of the attached object and the positioning status. When the attached object is a conductor and is positioned correctly, the conductor detection module 16 and the positioning detection module 17 transmit signals to the PCB. The board determines the hanging status by the circuit conduction status; if the hanging object is a conductor but not in place, the conductor detection module 16 is triggered while the placement detection module 17 is not triggered, which is judged as a false hanging, and the main communication module 7 will issue a warning; if the hanging object is a non-conductor, the placement detection module 17 is triggered but the conductor detection module 16 is not conductive, which is judged as an illegal operation, and the main communication module 7 will also issue a warning. The intelligent grounding wire monitoring device also includes an intelligent grounding rod 6, which is equipped with a Hall sensor 60cm from the bottom to detect the insertion depth. The main communication module 7, intelligent grounding rod 6, and intelligent grounding rod 18 are connected via LoRa communication to realize data interaction, thereby constructing a complete intelligent monitoring system.

[0017] Specifically, the lower end of the intelligent grounding rod 18 is provided with an operating rod 4, the upper part of the operating rod 4 is provided with a grounding hook body 1, the side of the grounding hook body 1 is provided with a fixing ear 2, and the inner side of the grounding hook body 1 is provided with a clamping tongue 3.

[0018] Specifically, the Hall effect sensor is located inside the grounding rod position sensor 5.

[0019] Specifically, the conductor detection module 16 includes two detection contacts on the left and right, and the hanging status detection mechanism includes an in-position detection contact. All detection contacts are connected to the PCB board, and the hanging status is determined by the circuit conduction status.

[0020] Specifically, the human body sensor switch 12 is equipped with a human body proximity alarm module. This module uses a microwave radar sensor to detect when a human body approaches and provides a voice reminder. When the microwave radar sensor detects that someone is approaching within the set danger distance range, the main communication module 7 will issue a "Do not approach" voice reminder to ensure personnel safety.

[0021] Specifically, the intelligent grounding rod 18 adopts a mounting structure with a fixed lug 2 and a clamping tongue 3. The clamping width can be flexibly adjusted by the operating rod 4 to adapt to grounding rods of different sizes, thus improving the versatility and applicability of the device.

[0022] In this implementation plan, such as Figure 5 The grounding operation procedure is as follows: First, place the main communication module 7 in a suitable position and power it on using the main module power button 11. The device operation status indicator 15 will light up, indicating that the device has started normally. Then, insert the smart grounding probe 6 into the ground. When the smart grounding probe 6 reaches an insertion depth of 60cm, the grounding probe positioning sensor 5 is triggered, and the grounding probe is connected via LoRa. The communication module 7 sends a signal to the main communication module 7, which then announces "The grounding rod is installed in place." Next, the intelligent grounding rod 18 is used for the connection operation. The operating lever 4 controls the grounding hook 1 and the clamping tongue 3 to connect to the target position. During connection, the conductor detection module 16 and the position detection module 17 begin operation. If the object being connected is a conductor and is properly connected, the conductor detection module 16 and the position detection module 17 transmit signals to the main communication module 7, which announces "Single-phase connection in place." If the connection is in place but the loop resistance is abnormal, the main communication module 7 prompts "Abnormal loop resistance, please check." If the connection operation is performed before the grounding rod is in place, the main communication module 7 prompts "Grounding rod not properly grounded, please remove the hook and check the grounding rod." Throughout the operation, if someone approaches the danger distance set by the human body induction switch 12, the microwave radar sensor detects the approaching person, and the main communication module 7 announces "Construction in progress, please stay away."

[0023] like Figure 6The dismantling process is as follows: When dismantling the grounding wire, the conductor detection module 16 and the positioning detection module 17 of the smart grounding rod 18 first detect the status of each phase hook. If the hook is not removed, the main communication module 7 will give a voice prompt "Hook not removed, do not remove the grounding rod". After all the hooks are removed, the conductor detection module 16 and the positioning detection module 17 will transmit a signal to the main communication module 7. The main communication module 7 will announce "Hook removed". At this time, the smart grounding rod 6 will be removed. After the removal is completed, the smart grounding rod 6 will send a signal to the main communication module 7. The main communication module 7 will then announce "Grounding rod removed", indicating that the entire dismantling operation is complete.

[0024] The working principle and usage process of this invention: Before use, check the communication main module 7, smart grounding rod 18, and smart grounding rod 6 respectively: 1. Check the appearance of the communication main module 7 for damage, and confirm that the device communication status indicator 8, abnormal indicator 9, charging indicator 10, main module power button 11, human body induction switch 12, charging port 13, abnormal information broadcast button 14, and device operation status indicator 15 are intact. Before use, charge the communication main module 7 through the charging port 13. The charging indicator 10 will light up during charging. After it is fully charged, the indicator status will change. Press and hold the main module power button 11 to turn on the communication main module 7. At this time, the device operation status indicator 15 will be constantly lit, indicating that the communication main module 7 is working normally. According to the actual operation requirements, some parameters of the communication main module 7 can be set through the internal circuit module, such as LoRa. 1. The communication frequency and the sensing distance of the human proximity alarm module, etc.; 2. Install the conductor detection module 16 and the position detection module 17 in the appropriate position of the smart grounding rod 18, and ensure that the grounding hook 1, the fixing ear 2, the clamping tongue 3 and the operating rod 4 are firmly connected. Adjust the clamping tongue 3 so that it can be flexibly clamped according to the actual size of the grounding rod used. Check whether the conductor detection module 16 and the position detection module 17 are connected to the PCB board and the lines are undamaged. Ensure that the detection function is normal. Pair the smart grounding rod 18 with the communication main module 7 through LoRa communication to ensure that the data transmission is normal; 3. Install the grounding rod position sensor 5 at 60cm from the bottom of the smart grounding rod 6. Ensure that the sensor is firmly installed and can work normally. Check that the appearance of the smart grounding rod 6 is not bent or damaged. Similarly, pair the smart grounding rod 6 with the communication main module 7 through LoRa communication to transmit the insertion depth detection data in real time; After inspection, the device was brought to the construction site. The main communication module 7 was placed in a location with a wide field of vision, safety, and easy operation. The intelligent ground probe 6 was then inserted vertically into the ground to a depth of 60cm. When the grounding rod is in place, the grounding rod positioning sensor 5 is triggered, sending a grounding positioning signal to the main communication module 7. The main communication module 7 immediately provides a voice prompt, "Grounding rod is installed in place." Then, holding the intelligent grounding rod 18, the operator controls the grounding hook 1 and the clamping tongue 3 via the operating lever 4 to attach them to the conductor that needs to be grounded. During the attachment process, the conductor detection module 16 and the positioning detection module 17 start working. If the object being attached is a conductor and is properly attached, the conductor detection module 16 and the positioning detection module 17 transmit signals to the main communication module 7, and the abnormal information broadcast button 14 broadcasts a voice prompt, "Single-phase attachment in place." If the attachment is in place but the loop resistance is abnormal, the main communication module 7 prompts, "Loop resistance abnormal, please check." If the attachment operation is performed before the grounding rod is in place, the main communication module 7 prompts, "Grounding rod is not properly grounded, please remove the hook and check the grounding rod." During the entire grounding operation, if someone approaches within 1 meter of the danger distance set by the human body induction switch 12, the microwave radar sensor detects the approaching person, and the main communication module 7 immediately provides a voice prompt, "Construction in progress, please stay away."

[0025] Dismantling operations after work completion: When dismantling the grounding wire, first operate the intelligent grounding rod 18. The conductor detection module 16 and the position detection module 17 automatically detect the status of each phase hook. If the hook is not removed, the main communication module 7 will give a voice prompt "Hook not removed, do not remove the grounding rod". After the operator removes all the hooks, the conductor detection module 16 and the position detection module 17 will transmit the signal that the hook has been removed to the main communication module 7. The main communication module 7 will announce "Hook removed". At this time, the operator will then remove the intelligent grounding rod 6. After the removal is completed, the intelligent grounding rod 6 will send a removal completion signal to the main communication module 7. The main communication module 7 will prompt "Grounding rod removed". The entire dismantling operation is successfully completed.

[0026] Regularly inspect and clean the device, and maintain the battery: Regularly inspect the appearance of each component of the intelligent grounding wire monitoring device to check for damage, wear, corrosion, etc. Check whether the indicator lights of the main communication module 7 are displaying normally and whether the button operation is sensitive; check whether the grounding hook 1, fixing ear 2, clamping tongue 3 and operating rod 4 of the intelligent grounding rod 18 are deformed or damaged, and whether the conductor detection module 16 and the position detection module 17 are oxidized, dirty or otherwise affecting the detection performance; check whether the intelligent grounding rod 6 is bent or broken, and whether the grounding rod position sensor 5 is intact; regularly clean the surface of the main communication module 7, intelligent grounding rod 18 and intelligent grounding rod 6 with a clean soft cloth to remove dust, dirt and other impurities. For key parts such as the conductor detection module 16 and the position detection module 17, you can use alcohol cotton balls to wipe them to ensure good contact and accurate detection; the main communication module 7 has a built-in battery. If the device is not used for a long time, the battery should be charged and discharged once every period of time to maintain battery activity and extend battery life. When the charging indicator light 10 shows that the battery power is low, charge it in time through the charging port 13.

[0027] Performance testing of the device: Regularly test all functions of the device, such as simulating insertion depth, different connection states, and human proximity, to check whether the device's detection and early warning functions are normal. If any faults or performance abnormalities are found, repairs or replacements should be carried out promptly to ensure that the device can operate reliably in power operations.

[0028] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
