[0037] The detailed description of the accompanying drawings is intended as an illustration of the current embodiments of the present invention and is not intended to represent the only form in which the present invention can be implemented. It should be understood that the same or equivalent functions can be accomplished by different embodiments that are intended to be included in the spirit and scope of the present invention.

[0038] See also Figures 1-2 , an embodiment of the present invention provides an intelligent detection device for a portable grounding wire, including an intelligent detection box, the intelligent detection box is designed to be clamped to the movable blocks of the wire end clamp and the grounding end clamp in an elastic buckle manner, and moves with the movable block;

[0039] The intelligent detection box has a built-in detection circuit;

[0040] When the intelligent detection box is clamped on the movable block of the wire end clamp, the detection circuit detects whether there is a wire at the clamping position of the wire end clamp and whether the wire is clamped tightly;

[0041] When the intelligent detection box is clamped on the movable block of the grounding terminal wire clamp, the detection circuit detects whether there is a grounding wire at the clamping position of the grounding terminal wire clamp and whether the grounding wire is clamped tightly.

[0042] Specifically, the smart detection box is used to detect the installation status of the three-phase wire or the grounding wire. The smart detection box is fixed on the movable block of the wire end clamp and the grounding end clamp by means of elastic clips. The wire end clamp and the grounding end clamp have the same structure and both have an operable movable block for clamping or loosening the wire or the grounding wire. The design of the elastic clip allows the detection box to be firmly attached to the movable block and to move with the movement of the movable block without falling off.

[0043] The smart detection box is integrated with detection circuits, which are responsible for collecting and analyzing data to determine the status of the grounding wire. When the smart detection box is clamped on the movable block of the wire end clamp, the detection circuit starts working. Its main task is to detect whether there is a wire at the clamping point of the wire end clamp and whether the wire is clamped. This can be achieved by measuring resistance, capacitance, distance or other physical parameters. Similarly, when the smart detection box is clamped on the movable block of the grounding end clamp, the detection circuit also works to detect whether there is a grounding wire at the clamping point of the grounding end clamp and whether the grounding wire is clamped.

[0044] In some embodiments, the detection circuit detects a first distance between the intelligent detection box and the wire, and determines whether there is a wire at the clamping position of the wire end clamp and whether the wire is clamped according to the first distance;

[0045] The detection circuit detects a second distance between the intelligent detection box and the grounding wire, and determines whether there is a grounding wire at the clamping position of the grounding terminal clamp and whether the grounding wire is clamped according to the second distance.

[0046] Specifically, when the smart detection box is clamped onto the movable block of the wire end clamp, the detection circuit will start the measurement function. The first distance refers to the distance between the smart detection box and the wire, which can be measured in a variety of ways, such as using an ultrasonic sensor, a laser rangefinder, a capacitive sensor, etc. If the distance between the smart detection box and the wire is within a preset safety range, it indicates that the wire has been correctly clamped in the wire end clamp. If the distance exceeds the preset range, it may mean that the wire is not clamped correctly or is not clamped tightly enough.

[0047] The same principle also applies to the grounding terminal clamp. When the smart detection box is clamped to the movable block of the grounding terminal clamp, the detection circuit will measure the second distance between the smart detection box and the grounding wire. The measurement of this distance can also use the sensor technology mentioned above. If the distance is within the safe range, it means that the grounding wire has been clamped correctly. If the distance exceeds the safe range, it may mean that the grounding wire is not clamped correctly or is not clamped tightly enough.

[0048] Through this distance measurement and judgment method, the intelligent detection box can monitor the installation status of the grounding wire in real time to ensure the safety and reliability of the grounding wire during the maintenance of the power system. If a problem is detected, the system can automatically alarm or prompt the operator to check, thereby avoiding potential dangers caused by improper installation of the grounding wire.

[0049] In some embodiments, the detection circuit includes a detection electrode and a capacitance detection chip. The detection electrode is used to input the change in external environmental capacitance to the capacitance detection chip, and the capacitance detection chip is used to obtain a capacitance change according to the change in external environmental capacitance. When the capacitance change reaches a first set threshold, a first detection signal indicating that there is a wire or a ground wire at the clamping point is output; when the capacitance change reaches a second set threshold, a second detection signal indicating that the wire or the ground wire is clamped is output.

[0050] Specifically, the detection circuit uses capacitance detection technology to monitor the installation status of the grounding wire. The detection electrode is part of the detection circuit. It is located on the smart detection box and is used to sense capacitance changes in the external environment. When the grounding wire (wire or grounding wire) is close to the detection electrode, a capacitance loop will be formed between the detection electrode and the grounding wire due to the existence of the grounding wire.

[0051] The capacitance detection chip is the core component of the detection circuit. It receives capacitance change signals from the detection electrode. The chip can measure and analyze these signals to determine the change in capacitance. When the intelligent detection box is clamped on the wire end clamp or the ground end clamp, the detection electrode will monitor the capacitance change caused by the proximity or contact of the ground wire. If the wire or ground wire exists and is close to the detection electrode, the capacitance value will change. When the capacitance change reaches a preset threshold (first set threshold), the capacitance detection chip will think that there is a wire or ground wire near the detection electrode. At this time, the chip will output a first detection signal, indicating that there is a wire or ground wire at the clamp. If the wire or ground wire not only exists, but is also clamped, the capacitance change will further increase. When the capacitance change reaches another higher set threshold (second set threshold), the capacitance detection chip will output a second detection signal, indicating that the wire or ground wire has been clamped.

[0052] In this way, the detection circuit can distinguish between the following situations:

[0053] Whether a conductor or ground wire is present;

[0054] Are the conductors or ground wires clamped?

[0055] The advantage of this capacitance detection method is that it does not require physical contact, can monitor the status of the ground wire non-invasively, and can adapt to different environmental conditions. In addition, due to the sensitivity of the capacitance detection chip, it can provide accurate detection results, thereby improving the safety and efficiency of power system maintenance.

[0056] In some embodiments, Figure 3 As shown, the intelligent detection device further includes a wireless communication module and a single chip microcomputer, wherein the wireless communication module is used to communicate with the intelligent detection device clamped to the other phase conductor end clamp and the intelligent detection device clamped to the grounding end clamp, receive the detection signal output by the intelligent detection device clamped to the other phase conductor end clamp and the detection signal output by the intelligent detection device clamped to the grounding end clamp, and transmit it to the single chip microcomputer for processing;

[0057] The single chip microcomputer is used to give prompts or alarms according to the detection signals output by the intelligent detection devices clamped to the wire clamps at the ends of other phase conductors and the detection signals output by the intelligent detection devices clamped to the wire clamps at the grounding ends.

[0058] Specifically, the wireless communication module is a component of the intelligent detection device, which allows wireless communication between devices. In this embodiment, the wireless communication module is a Bluetooth communication module, which is used to communicate with other intelligent detection devices clamped to the phase conductor end clamp and the intelligent detection device clamped to the grounding end clamp. Through Bluetooth communication, detection signals from other intelligent detection devices can be received, that is, whether there is a wire or a grounding wire in the wire end clamp or the grounding end clamp, and whether the wire or the grounding wire is clamped.

[0059] The microcontroller unit (MCU) is the control center of the intelligent detection device. It is responsible for processing the received signals and making corresponding decisions. The MCU receives signals from the wireless communication module, which include the detection signals output by the intelligent detection devices on the wire clamps at the other phase conductor ends and the intelligent detection devices on the grounding terminal clamp. The MCU will analyze and process the received detection signals. For example, if the intelligent detection device of a phase conductor end clamp reports that the wire is not clamped, and the intelligent detection device of the grounding terminal clamp reports that the grounding wire is in normal condition, the MCU needs to evaluate this information to determine the overall safety status. Based on the analysis results, the MCU can perform the following operations:

[0060] If all detection devices report that everything is normal, the microcontroller may not need to take any action.

[0061] If an abnormal condition is detected, the microcontroller can trigger a prompt or alarm, which may be through sound, visual signal (such as flashing LED light) or by wirelessly sending a notification to the operator's portable device (such as a smartphone or tablet).

[0062] In this way, the intelligent detection device can not only independently monitor the status of the grounding wire, but also work in conjunction with other devices to provide a comprehensive system monitoring solution. This integrated communication and processing capability improves the accuracy and efficiency of grounding wire detection, while also enhancing the safety of power system maintenance.

[0063] In some embodiments, the wireless communication module is a Bluetooth communication module, the Bluetooth communication module of the intelligent detection device clamped to the grounding terminal clamp is the host, and the Bluetooth communication module of the intelligent detection device clamped to the three-phase wire terminal clamp is the slave.

[0064] In some embodiments, the single chip microcomputer is specifically used for:

[0065] During the hooking stage, if the grounding end clamp is not connected to the grounding wire, and the ABC three-phase wire end clamps are not connected to the wires, it is suggested to connect the grounding end clamp first;

[0066] During the hooking stage, if the grounding end clamp is not connected to the grounding wire, and the end clamp of any phase conductor in the three phases ABC is connected to the conductor, an alarm is issued;

[0067] During the removal stage, if the grounding terminal clamp is connected to the grounding wire and the ABC three-phase wire terminal clamps are all connected to the wires, it is suggested to remove the wire terminal clamps first;

[0068] During the removal stage, if the grounding terminal clamp is not connected to the grounding wire and the terminal clamp of any phase conductor among the three phases ABC is connected to the conductor, an alarm is issued.

[0069] The anti-misoperation logic of the microcontroller is shown in the following table:

[0070]

[0071] In some embodiments, Figure 4 As shown, the intelligent detection device also sends a detection signal to a remote server via a wireless network, and the server analyzes the detection signal of the intelligent detection device clamped to the three-phase conductor end clamp and the detection signal of the intelligent detection device clamped to the ground end clamp to determine whether to send a prompt or alarm notification to the operator's mobile phone.

[0072] Specifically, the intelligent detection device not only has local monitoring and alarm functions, but also can communicate with the remote server through a wireless network to achieve remote monitoring and data recording. The intelligent detection device has a built-in or external wireless network communication module (such as Wi-Fi, cellular network, etc.), which enables it to send the detected signals to the remote server through the Internet. The remote server is a data storage and processing center that receives detection signals from the intelligent detection device. The software running on the server can analyze these signals to determine the safety status of the system. The server analyzes the detection signals received from the intelligent detection device clamped to the ABC three-phase wire end clamp and the intelligent detection device clamped to the grounding end clamp. The purpose of the analysis is to determine whether the grounding wire and the wire are correctly connected and fixed, and whether there are potential safety risks; if the server analysis results show that the system status is normal, it may not need to take any action; if an abnormal situation is detected, the server can automatically send a prompt or alarm notification to the operator's mobile phone, which can be achieved through SMS, application push notifications or other forms of mobile communication.

[0073] Through this remote monitoring and notification system, the following benefits are achieved:

[0074] Real-time monitoring: Operators can understand the status of the ground wire in real time, even if they are not on site.

[0075] Logging and reporting: The server can record all detection data for post-analysis, reporting and auditing.

[0076] Remote support: Experts and technicians can access data remotely to provide technical support and make decisions.

[0077] Enhanced safety: With timely notifications, potential safety issues can be responded to quickly, reducing the risk of accidents.

[0078] In some embodiments, the server is specifically used to:

[0079] During the hooking stage, if the grounding end clamp is not connected to the grounding wire, and the ABC three-phase wire end clamps are not connected to the wires, it is suggested to connect the grounding end clamp first;

[0080] During the hooking stage, if the grounding end clamp is not connected to the grounding wire, and the end clamp of any phase conductor in the three phases ABC is connected to the conductor, an alarm is issued;

[0081] During the removal stage, if the grounding terminal clamp is connected to the grounding wire and the ABC three-phase wire terminal clamps are all connected to the wires, it is suggested to remove the wire terminal clamps first;

[0082] During the removal stage, if the grounding terminal clamp is not connected to the grounding wire and the terminal clamp of any phase conductor among the three phases ABC is connected to the conductor, an alarm is issued.

[0083] Specifically, the anti-misoperation logic of the server is as shown in the above table.

[0084] Furthermore, the intelligent detection device uses a universal QR code label, and during the production stage, the core information is entered into the QR code: device model (intelligent portable grounding wire), wireless MAC address, and factory date, and it is affixed to the intelligent grounding box, so that the warehousing and outbound processes of the grounding wire can be completed by quickly scanning the QR code, and the inventory files can be updated in real time, realizing precise and efficient asset management.

[0085] When the operator receives the grounding wire, he or she can scan the QR code through the application to obtain the information of the grounding wire, which can quickly bind the operator to the MAC address of the grounding wire and the work ticket. Combined with the background database sharing, the grounding wire management system can effectively track whether the operator strictly follows the operating procedures of the grounding wire. When any omissions, hanging before connecting, omissions, or hanging or removing out of sequence occur, the system will send a warning message to the responsible operator to ensure compliance with the operation.

[0086] At the inventory monitoring level, the inventory management system uses the latest inspection date and validity period data to automatically monitor the inspection cycle, warn of re-inspection in advance, and eliminate the hidden dangers of overdue use. For ground wires that pass the re-inspection, their latest inspection records are automatically refreshed by the system, and smoothly transition to the next inspection cycle supervision to ensure continuous safe and compliant use.

[0087] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
