Description

Technical Field

[0001] The present application relates to the field of smart grid technology, and in particular to a method, device, medium, product, grounding detection system and grounding wire for detecting the status of an intelligent grounding wire based on Beidou high-precision positioning and multiple communication modes. Background Art

[0002] As power systems continue to develop and become more complex, the requirements for power supply system safety are also increasing. Among them, the detection and monitoring of the connection status of ground wires has become a key link in ensuring the stable operation of power facilities.

[0003] Commonly, sensors that continuously monitor ground wires in real time can achieve high-precision, high-security real-time detection. By continuously detecting and monitoring the ground wire's status, these sensors can promptly detect potential faults and ensure the safe operation of power equipment. However, this approach consumes relatively high computing resources, especially in large-scale deployments, which can lead to slow system response and increased maintenance costs.

[0004] On the other hand, while using interval detection sensors can save computing resources and reduce system burden, safety issues have raised concerns. Interval detection often fails to capture transient faults in real time, which can prevent maintenance personnel from promptly identifying safety hazards and increase the risk of equipment failure. Therefore, in the current technological context, finding a balance between safety and computing resource consumption has become a critical issue that needs to be addressed in ground wire detection and monitoring technology.

Moreover, by introducing an interval time and determining the interval time of each detection based on the number of times the grounding wire remains connected indicated by the connection status obtained by the second sensor device, the waiting time of the second sensor device before each detection can be different, and the time for the second sensor device to send the detection result of the grounding wire connection status to the processing module can be more dispersed, thereby preventing the second sensor devices of multiple grounding wires from sending the detection results to the processing module at the same time, causing data concurrency at the processing module.

[0061] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0062] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0063] The intelligent ground wire status detection method based on Beidou high-precision positioning and multiple communication modes provided in the embodiment of the present application can be applied to Figure 1The ground detection system 100 shown in FIG. The ground detection system 100 includes a processing module 110, multiple grounding wires, and multiple first sensing devices 120 and multiple second sensing devices 130 connected to the processing module 110. Each grounding wire corresponds to one first sensing device 120 and one second sensing device 130. The first sensing device 120 is used to continuously detect the connection status of the corresponding grounding wire, while the second sensing device 130 is used to intermittently detect the connection status of the corresponding grounding wire. The ground detection system 100 can be applied to power supply systems.

[0064] The power supply system refers to the entire power transmission and distribution network that delivers electricity from power plants to consumers (such as homes and industrial enterprises). The power supply system can involve power generation equipment, substations, transmission lines, distribution systems, distribution equipment, and terminal electrical equipment.

[0065] Power generation equipment, for example, includes generators, thermal power plants, nuclear power plants, hydropower plants, wind farms, and solar power systems, which convert various forms of energy (such as chemical, mechanical, nuclear, and solar) into electrical energy. Substations, for example, include step-up and step-down substations, which are used to increase the voltage of electricity generated by power plants to reduce energy losses during transmission and then reduce the voltage to a safe and usable level before the electricity reaches the user terminal. Transmission lines refer to high-voltage transmission lines (such as overhead lines and underground cables) used to transmit electricity over long distances from power plants to substations or directly to user terminals. The power distribution system, including distribution transformers, distribution lines, and distribution cabinets, is used to reduce the voltage and distribute electricity to end users, such as homes, businesses, and industrial facilities. Distribution equipment, including circuit breakers, contactors, fuses, and distribution boards, controls and protects the power supply, ensuring power is shut off in the event of a fault and maintaining system safety. Consumers at the terminal can include lighting, appliances, industrial machinery, and other electrical equipment, which receive and use electrical energy to perform various electrical operations.

[0066] In the power supply system, grounding wires are required in almost every link. In substations, the equipment casings of power stations usually need to be grounded to ensure the safe operation of generators and prevent the risk of electric shock caused by leakage or electrical faults. In substations, grounding wires are used to ground transformers, switchgear and other high-voltage equipment to avoid high voltage generated by equipment in the event of a fault, protecting personnel and equipment. On high-voltage transmission lines, grounding wires are also installed under railways and cables to prevent lightning strikes and electrostatic discharge to prevent damage to lines and equipment. In distribution systems, distribution transformers are usually connected to the earth through grounding wires to ensure the safety of equipment in the event of a short circuit or fault. The metal casings of distribution cabinets, switches and sockets need to be connected to the grounding system through grounding wires to prevent leakage accidents. The casings of terminal user equipment must also be grounded to ensure that current can be safely introduced into the ground in the event of a fault, reducing the risk of electric shock.

[0067] The intelligent grounding wire status detection method based on Beidou high-precision positioning and multiple communication modes in this embodiment can be applied to the detection of the connection status of the grounding wire at any location in the power supply system.

[0068] The processing module 110 may be a central processing unit, or other general-purpose processor, digital signal processor, or application-specific integrated circuit. The general-purpose processor may be a microprocessor or any conventional processor. The steps of the method disclosed in the present invention may be directly executed by a hardware processor or by a combination of hardware and software modules within the processor.

[0069] The first sensing device 120 can use a Hall effect sensor to detect changes in the magnetic field of the ground wire. A fixed current flows inside the Hall effect sensor, and the Hall voltage generated by this current can be used to detect the magnetic field that intersects with it. When an external magnetic field exists, the Hall voltage will change with changes in the strength and direction of the magnetic field. As an example, when the ground wire is well grounded, the leakage current through the ground wire may generate a tiny magnetic field, and the Hall effect sensor can detect changes in this magnetic field; if the ground wire is disconnected or poorly grounded, the leakage current of the ground wire will decrease, which will cause the magnetic field detected by the Hall sensor to change. The Hall voltage output by the Hall effect sensor can be converted into a voltage signal proportional to the strength of the detected magnetic field and output to the processing module 110.

[0070] The second sensing device 130 may be a voltage sensor, a current sensor, an infrared sensor, or a photoelectric sensor to achieve interval detection.

[0071] When installing the first sensor device 120 and the second sensor device 130 , it is necessary to ensure that the first sensor device 120 and the second sensor device 130 are located close to the connection point of the grounding wire to accurately monitor the grounding status.

[0072] It should be noted that this application does not limit the specific hardware devices used by the first sensing device 120 and the second sensing device 130.

[0073] In one embodiment, only one type of sensing device may be provided in the ground detection system 100 , and the sensing device only needs to be able to implement continuous detection of the first sensing device 120 and interval detection of the second sensing device 130 .

[0074] In one embodiment, the ground detection system 100 further includes a third sensor device 140 connected to the processing module 110. The third sensor device 140 is configured to collect the contact resistance value at the corresponding connection point of the ground wire. The third sensor device 140 can be, for example, a ground resistance meter or a micro-ohmmeter.

[0075] like Figure 2 As shown, in one embodiment, a grounding wire 200 is provided. The grounding wire 200 can be applied to the above-mentioned grounding detection system 100 .

[0076] The grounding wire 200 includes a hanging component 210 , a grounding component 220 and a communication component 230 . The hanging component 210 and the grounding component 220 are connected via a soft copper wire 240 .

[0077] The hanging component 210 includes a hanging part and a connecting part. The hanging part can be set to a hook shape, for example, and the hanging part is also provided with an elastic component. When the grounding wire 200 is hung with any device that needs to be grounded in the power supply system through the hanging part of the hanging component 210, the equipment in the power supply system can be limited in the hanging part and clamped by the elastic component to prevent the equipment in contact with the hanging part from shifting, so that the grounding wire 200 is loosened from the equipment; the connecting part of the hanging component 210 can be in the form of a long stick, and the end of the connecting part close to the hanging part can be connected to the soft copper wire 240, and the end of the connecting part away from the hanging part can be covered with insulating materials such as silicone pads to facilitate the staff to hold and move the hanging part.

[0078] It should be noted that the communication component 230 can be communicatively connected to the processing module 110 in the grounding detection system 100. Upon receiving a detection instruction output by the processing module 110, the communication component 230 can continuously detect the connection status of the ground wire using the first sensor device. If the connection status obtained by the first sensor device 120 indicates that the hook assembly 210 in the ground wire remains connected within a preset time period, the communication component 230 can control the first sensor device 120 to stop detecting and, after waiting for an initial interval, use the second sensor device 130 to detect the connection status of the ground wire. If the connection status obtained by the second sensor device 130 indicates that the hook assembly 210 in the ground wire 200 remains connected, the communication component 230 can determine the interval length for the next detection by the second sensor device 130 based on the number of times the connection status obtained by the second sensor device indicates that the ground wire remains connected. After waiting for the interval, the communication component 230 can continue to detect the connection status of the hook assembly 210 in the ground wire. Furthermore, the communication component 230 can send the connection status obtained by the first sensor device 120 and the second sensor device 130 to the processing module 110.

[0079] The communication component 230 also has Beidou positioning capabilities and can be combined with the Beidou satellite navigation system to achieve centimeter-level precision positioning of the ground wire 200. The communication component 230 can, for example, communicate with the processing module 110 via 433 MHz wireless transmission or 4G Cat1 wide-area terrestrial mobile communication. The first and second sensor devices 120 and 130 can, for example, communicate with the communication component 230 using Beidou short message communication or wide-area terrestrial mobile communication.

[0080] The wide-area communication mode can be a 4G Cat1 wide-area terrestrial mobile communication mode. Beidou short message communication is a communication mode that uses the Beidou satellite navigation system to send and receive short messages. It is suitable for narrowband communication scenarios in areas without terrestrial mobile communication signal coverage. When the first sensor device and the second sensor device are in an environment without a terrestrial mobile communication network, the first sensor device and the second sensor device can send and receive information through the Beidou satellite navigation system. It should be noted that when the first sensor device and the second sensor device communicate with the communication component 230, the information sent is encrypted. For example, the national encryption SM4 algorithm can be used to encrypt the information to be sent.

[0081] Exemplarily, the above-mentioned communication component 230 also supports adaptive power regulation. The communication component 230 can dynamically adjust the current of the external power input according to the remaining power of its own battery, control the current within the range of 0.5A-2A, and can achieve a charging efficiency of ≥90%, thereby realizing a fast charging function.

[0082] In one embodiment, a method for detecting the state of an intelligent grounding wire based on Beidou high-precision positioning and multiple communication modes is provided. This embodiment uses the detection method to be applied to the processing module in the above-mentioned grounding detection system as an example. It should be noted that the detection method can also be applied to the communication component included in the grounding wire in the above-mentioned grounding detection system, or to a system including the processing module and the communication component included in the grounding wire, and is implemented through the interaction between the processing module and the communication component included in the grounding wire, such as Figure 3 As shown, the detection method includes:

[0083] Step 302: For any ground wire, use a first sensor device to continuously detect the connection status of the ground wire.

[0084] In this embodiment, the processing module can generate a trigger detection instruction and send it to the first sensor device to control the first sensor device to start continuously monitoring the connection status of the grounding wire. For example, the first sensor device will continuously detect the magnetic field of the grounding wire and generate a corresponding Hall voltage value and send it to the processing module.

[0085] As an example, when the Hall voltage value reaches a preset voltage value threshold, the processing module can determine that the ground wire is in a connected state; when the Hall voltage value is less than the preset voltage value, it can be considered that the leakage current of the ground wire becomes smaller, and the processing module can determine that the ground wire is disconnected or poorly grounded.

[0086] Step 304: When the connection status acquired by the first sensing device indicates that the ground wire remains connected within the preset time, the first sensing device is controlled to stop detecting, and after waiting for the initial interval, the second sensing device is used to detect the connection status of the ground wire.

[0087] If within the preset time period, the connection status obtained by the first sensor device indicates that the ground wire remains connected, it can be considered that the current connection status of the ground wire is relatively stable and the risk of disconnection or poor grounding is relatively small. At this time, the processing module can generate a stop detection instruction and send it to the first sensor device to control the first sensor device to stop detecting the magnetic field of the ground wire and stop generating Hall voltage values.

[0088] At the same time, the processing module may generate another trigger detection instruction and send it to the second sensing device to control the second sensing device to start continuously monitoring the connection status of the ground wire.

[0089] The initial interval duration may be a preset duration, for example, 20 ms.

[0090] Step 306: When the connection status obtained by the second sensor device indicates that the ground wire remains connected, determine the interval duration corresponding to the next detection by the second sensor device based on the number of times the connection status obtained by the second sensor device indicates that the ground wire remains connected.

[0091] In this embodiment, when the connection status obtained by the second sensing device for the nth time indicates that the ground wire remains connected, the processing module can determine the interval length required to wait after the second sensing device completes the nth detection based on the number n times the connection status obtained by the second sensing device indicates that the ground wire remains connected, and control the second sensing device to perform the n+1th detection after the waiting interval length.

[0092] From this, it can be seen that the interval between any two detections of the second sensing device is determined based on the number of times the connection status obtained by the second sensing device indicates that the ground wire remains connected, and the length of the interval is related to the number of times the connection status obtained by the second sensing device indicates that the ground wire remains connected.

[0093] Step 308: After the waiting interval, continue to detect the connection status of the ground wire using the second sensing device.

[0094] The above detection method can first use the first sensor device for continuous detection to detect the connection status of the grounding wire, and when the time for which the grounding wire remains connected reaches a preset time and the risk of disconnection or poor grounding is relatively small, switch to the second sensor device for interval detection to continue detecting the connection status of the grounding wire, thereby avoiding long-term continuous detection of the connection status of the grounding wire, thereby saving computing resources. In addition, by introducing the interval time and determining the interval time of each detection based on the number of times the connection status obtained by the second sensor device indicates that the grounding wire remains connected, the waiting time of the second sensor device before each detection can be different, and the time for the second sensor device to send the detection result of the grounding wire connection status to the processing module can be more dispersed, thereby preventing the second sensor devices of multiple grounding wires from sending detection information to the processing module at the same time, causing data concurrency at the processing module.

[0095] In some optional embodiments, step 306 includes:

[0096] Determine a reference duration based on the number of times the connection status indication ground wire obtained by the second sensing device remains connected, the initial interval duration, and a preset reference duration;

[0097] Determine the jitter duration based on a preset jitter range and a reference duration;

[0098] Based on the reference duration and the jitter duration, an interval duration corresponding to the second sensing device is determined.

[0099] The determining of the reference duration based on the number of times the connection status indication ground wire obtained by the second sensing device remains connected, the initial interval duration, and the preset reference duration includes:

[0100] multiplying the number of times the connection status indication ground wire obtained by the second sensing device remains connected by the initial interval duration;

[0101] The multiplied value is compared with the preset reference duration. When the preset reference duration is smaller, the preset reference duration is used as the benchmark duration; otherwise, the multiplied value is used as the benchmark duration.

[0102] For example, the following formula can be used to determine the benchmark duration:

[0103] wait_time1 = min(base_time * 2^attempt, max_backoff)

[0104] Among them, wait_time1 represents the benchmark duration; base_time represents the initial interval duration; attempt represents the number of times the connection status indication ground wire obtained by the second sensing device remains connected; max_backoff represents the preset reference duration.

[0105] It should be noted that the preset reference duration is greater than the initial interval duration.

[0106] Then, as the number of times the connection status obtained by the second sensing device indicates that the ground wire remains connected gradually increases, the processing module can first use the smaller value base_time * 2^attempt as the benchmark duration. After the number of times the connection status obtained by the second sensing device indicates that the ground wire remains connected reaches a certain value, when base_time * 2^attempt is greater than max_backoff, the processing module can first use the smaller value max_backoff as the benchmark duration.

[0107] Determine the jitter duration based on the preset jitter range and reference duration, including:

[0108] Randomly select a value from the duration jitter range and multiply it by the base duration;

[0109] The value obtained by multiplication is used as the jitter duration.

[0110] For example, the following formula can be used to determine the jitter duration:

[0111] jitter = random(10ms, 20ms) * wait_time1

[0112] Where jitter represents the jitter duration, (10ms, 20ms) represents the jitter range, and wait_time1 represents the base duration. The jitter range can be customized to control the length and dispersion of the intervals.

[0113] Furthermore, for example, the following formula may be used to determine the interval duration:

[0114] wait_time2 = max(0, wait_time1 + jitter)

[0115] wait_time2 indicates the interval duration.

[0116] In this embodiment, the processing module can set the reference time by taking a smaller value as the reference time, so that as the number of times the connection status obtained by the second sensor device indicates that the ground wire remains connected gradually increases, the extension of the reference time is first positively correlated with the increase in the number of times the connection status obtained by the second sensor device indicates that the ground wire remains connected, and when the number of times the connection status obtained by the second sensor device indicates that the ground wire remains connected reaches a specific value, the reference time is equal to the preset reference time and remains unchanged, and by introducing a time jitter range, the interval time is made more random, so that the time for the second sensor device to send the information on the detection of the ground wire connection status to the processing module becomes more dispersed, thereby preventing data concurrency in the processing module.

[0117] In some optional embodiments, the detection method further comprises:

[0118] When the connection status acquired by the second sensing device indicates that the ground wire is not connected, the second sensing device is controlled to stop detection, the first sensing device is used again to detect the connection status of the ground wire, and the initial interval duration is updated to obtain an updated interval duration;

[0119] When the connection status acquired by the first sensing device again indicates that the ground wire remains connected within the preset time, the first sensing device is controlled to stop detection, and after waiting for the update interval, the second sensing device is used again to detect the connection status of the ground wire.

[0120] When the connection status obtained by the second sensor device indicates that the grounding wire is disconnected or poorly grounded, the processing module may consider that the current connection status of the grounding wire is unstable and the risk of subsequent grounding wire disconnection or poor grounding is high. At this time, the processing module may generate a stop detection instruction and send it to the second sensor device to control the second sensor device to stop detecting the connection status of the grounding wire. At the same time, the processing module may generate a trigger detection instruction again and send it to the first sensor device to control the first sensor device to resume continuous monitoring of the connection status of the grounding wire.

[0121] If the connection status obtained by the first sensing device indicates that the grounding wire remains connected within a preset time after the first sensing device resumes detection, the processing module may deem that the connection status of the current grounding wire has returned to stability, and the risk of disconnection or poor grounding is small. At this time, the processing module may generate a stop detection instruction and send it to the first sensing device to control the first sensing device to stop detection, and update the initial interval duration to obtain the updated interval duration. After waiting for the updated interval duration, another trigger detection instruction may be generated again and sent to the second sensing device to control the second sensing device to resume continuous monitoring of the connection status of the grounding wire.

[0122] The above-mentioned detection method can dynamically adjust the monitoring strategy through flexible switching between the first sensing device and the second sensing device to ensure real-time monitoring and reliability of the grounding wire connection status, which not only improves the efficiency and flexibility of grounding status monitoring, but also ensures the timeliness of handling abnormal conditions; and each time the first sensing device and the second sensing device are switched, the initial interval duration can be updated to make the interval duration more random, so that the time for the second sensing device to send the detection result of the grounding wire connection status to the processing module becomes more dispersed, thereby preventing data concurrency in the processing module.

[0123] In some optional embodiments, updating the initial interval duration to obtain the update interval duration includes:

[0124] determining the number of times the connection status indication ground wire remains connected obtained by the second sensing device during a previous detection process;

[0125] Determine a numerical range whose number of times matches from a plurality of preset continuous numerical ranges; the plurality of numerical ranges correspond one to one with the plurality of updated numerical values;

[0126] Based on the initial interval duration, the update value corresponding to the numerical range of the cumulative number of times meets is added to obtain the update interval duration.

[0127] When the processing module switches the first sensing device to the second sensing device for detection, the processing module can obtain the number of times the connection status indication grounding wire remains connected during the previous detection of the second sensing device, and match the number with multiple pre-set numerical ranges, and each numerical range corresponds to an updated value. Then, based on the initial interval duration, the updated value corresponding to the numerical range that the number of times meets is accumulated to obtain the update interval duration.

[0128] It should be noted that a larger numerical range corresponds to a larger update value. Through this setting, the initial interval duration for grounding wires with a lower risk of disconnection or poor grounding can be extended to reduce the detection frequency.

[0129] For example, the processing module is pre-set with three numerical ranges of less than 5 times, 5 times to 20 times, and greater than 20 times, and the update value corresponding to the numerical range of less than 5 times is -10ms, the update value corresponding to the numerical range of 5 times to 20 times is 0ms, and the update value corresponding to the numerical range of greater than 20 times is 10ms. When the processing module switches the first sensing device to the second sensing device for detection, the processing module can obtain the connection status indication of the grounding wire remaining connected 60 times during the previous detection of the second sensing device. At this time, the processing module can determine that the update value is 10ms. At this time, 10ms is superimposed on the initial interval duration to extend the waiting time after switching the first sensing device to the second sensing device.

[0130] The above detection method can determine the risk of the grounding wire being disconnected or poorly grounded based on the number of times the grounding wire remains connected as indicated by the connection status obtained by the second sensing device during the previous detection, and extend or shorten the initial interval duration based on different risks, thereby increasing the detection frequency of grounding wires with a greater risk of disconnection or poor grounding, and reducing the detection frequency of grounding wires with a lower risk of disconnection or poor grounding. This not only saves computing resources, but also makes the interval duration more random, so that the time for the second sensing device to send the detection result of the grounding wire connection status to the processing module becomes more dispersed, thereby preventing data concurrency in the processing module.

[0131] In some optional embodiments, the detection method further comprises:

[0132] When the connection status indicates that the ground wire is not connected, obtaining coordinate information of the ground wire and a contact resistance value collected by a third sensor device; the coordinate information is determined based on the Beidou satellite navigation system and the Beidou positioning function on the ground wire;

[0133] When the coordinate information indicates that the grounding wire deviates from a preset standard position and the contact resistance value reaches a preset resistance threshold, a prompt message is output.

[0134] As an example, the Beidou satellite navigation system includes multiple Beidou base stations and a data processing system; the Beidou base stations are pre-set within the power supply system, the coordinate positions of these Beidou base stations are known, and they can receive Beidou satellite signals from multiple Beidou satellites. The Beidou satellite signals include the coordinate positions of the Beidou satellites, the time when the Beidou satellites send the Beidou satellite signals, the time when the Beidou satellite signals are received by the Beidou base stations and other necessary information.

[0135] Furthermore, the Beidou base station can receive Beidou satellite signals, demodulate and process them, and then send them to the data processing system. The data processing system can analyze the signals received by each Beidou base station and determine the possible sources of errors: multipath effect: signal reflection causes signal arrival time delay; atmospheric delay: the impact on the signal when passing through the atmosphere; positioning error: the accuracy limitation of the Beidou satellite navigation system itself, and ultimately determine the differential data information.

[0136] Subsequently, the communication component on the grounding wire uses the differential data information sent by the Beidou satellite navigation system and the received Beidou satellite signal data to accurately calculate the high-precision location information of the grounding wire.

[0137] It should be noted that the present application does not impose any restrictions on the method for obtaining the coordinate information of the grounding wire, and it is sufficient to be able to obtain the coordinate information of the grounding wire with high precision at the centimeter level.

[0138] The default standard location for the ground wire is the grounding point established according to engineering design and safety regulations. Deviating from this standard location can cause disconnection or poor contact, impacting the safety of equipment in the power supply system.

[0139] When the coordinate information of the grounding wire deviates from the preset standard position and the contact resistance value reaches the preset resistance threshold, the processing module can output prompt information to several preset smart terminals. The smart terminals are used to display the prompt information to maintenance personnel. The prompt information may include: alarm information: such as "Warning: The grounding wire position is offset and reaches the contact resistance threshold, please check the grounding connection!"; the current grounding wire coordinate information and the actual value of the contact resistance; prompts for required operations, such as "Check the physical connection of the grounding wire to ensure there is no damage" and "Repair or reconfigure the grounding wire as soon as possible to restore it to the standard position and reduce the contact resistance".

[0140] Such output information not only reminds the maintenance personnel of the power supply system to pay attention to the severity of the problem, but also provides necessary data support and guidance for subsequent investigation and rectification.

[0141] In one embodiment, if Figure 4As shown, a grounding detection system 400 is provided. This grounding detection system 400 is applied to the above-mentioned power supply system. The grounding detection system 400 includes a processing module 410, grounding lines L1, L2, and L3 installed in a substation, and three first sensing devices 420, three second sensing devices 430, and three third sensing devices 440 connected to the processing module 410. A first sensing device 420, a second sensing device 430, and a third sensing device 440 are respectively installed at the locations where the grounding lines L1, L2, and L3 are installed. The grounding lines L1, L2, and L3 in the substation correspond to preset standard positions P1, P2, and P3, respectively. The initial interval duration corresponding to the second sensing device 330 is preset to 5ms, the preset reference duration is set to 1000ms, and the duration jitter range is set to (10ms, 20ms).

[0142] Specifically, for example, the staff sends a detection instruction to the processing module 310 by clicking on a pre-integrated virtual component in the feature interface displayed on the terminal human-computer interaction interface. The processing module 310 then generates a trigger detection instruction and sends it to the three first sensor devices 420 corresponding to the grounding lines L1, L2 and L3 at the same time to control the first sensor devices 420 to start continuously monitoring the connection status of the corresponding grounding lines.

[0143] For example, the information collected by the first sensor device 420 corresponding to the grounding line L1 indicates that the grounding line L1 is disconnected when the detection time of the first sensor device 420 does not reach the preset time. At this time, the processing module 410 can obtain the coordinate information of the grounding line L1, and collect the contact resistance value at the connection point corresponding to the grounding line L1 through the third sensor device corresponding to the grounding line L1. When the coordinate information of the grounding line L1 indicates that the grounding line L1 deviates from the preset standard position P1 and the contact resistance value reaches the preset resistance threshold, a prompt message is output to prompt the staff to go to the connection line L1 for troubleshooting. During this period, the first sensor device 420 can still continue to detect the connection status of the connection line L1, and when the connection status of the connection line L1 indicates that the grounding line L1 remains connected, the detection time of the first sensor device 420 is re-timed.

[0144] In addition, the processing module 410 determines that the grounding lines L1 and L2 remain connected within a preset time period based on the information continuously collected by the two first sensing devices 320 corresponding to the grounding lines L2 and L3. At this time, the processing module 410 can consider that the connection status of the grounding lines L1 and L2 is relatively stable, and the possibility of disconnection or poor contact is relatively small. At this time, the processing module 410 generates a stop detection instruction and sends it to the two first sensing devices 420 corresponding to the grounding lines L2 and L3 to control the two first sensing devices 420 corresponding to the grounding lines L2 and L3 to stop detection, and after waiting for the initial interval length t1, generates another trigger detection instruction and sends it to the second sensing device 430 corresponding to the grounding lines L2 and L3 to control the second sensing device 430 corresponding to the grounding lines L2 and L3 to start interval monitoring of the connection status of the grounding lines L2 and L3.

[0145] like Figure 5 As shown, for example, for the ground line L2, before the second sensing device 430 corresponding to the ground line L2 performs the second detection, the processing module 410 can indicate the number of times the ground line L2 remains connected based on the connection status obtained by the second sensing device 330 1, calculate the reference duration wait_time1 (L2-t1) = min(5ms * 2^1, 1000ms) = 10ms, and randomly extract a duration from the duration jitter range (10ms, 20ms), for example, 15ms, further calculate the jitter duration jitter (L2-t1) = 15ms * 10ms = 150ms, and finally calculate the interval duration wait_time2 (L2-t1) = max(0, 150ms +100ms) = 250ms. After waiting for the interval length wait_time2 (L2-t1), a trigger detection instruction is generated again and sent to the second sensor device 430 corresponding to the ground line L2, so as to control the second sensor device 430 corresponding to the ground line L2 to perform a second connection status detection on the ground line L2. Similarly, the interval length wait_time2 (L2-t2) that the second sensor device 430 corresponding to the ground line L2 needs to wait for before performing the third detection, the interval length wait_time2 (L2-t3) that the second sensor device 430 needs to wait for before performing the fourth detection... are calculated.

[0146] Similarly, for the grounding wire L3, the second sensing device 430 corresponding to the grounding wire L3 can calculate the interval length wait_time2 (L3-t1) before performing the second detection, the interval length wait_time2 (L3-t2) required to wait before performing the fourth detection, the interval length wait_time2 (L3-t3) required to wait before performing the fifth detection...

[0147] Accordingly, after switching the first sensing device 420 to the second sensing device 430, the processing module 410 can receive the information collected by the second sensing device 430 corresponding to the ground line L2 at wait_time2(L2-t1), wait_time2(L2-t1)+wait_time2(L2-t2), wait_time2(L2-t1)+wait_time2(L2-t2)+wait_time2(L2-t3)..., and receive the information collected by the second sensing device 430 at intervals at wait_time2(L3-t1), wait_time2(L3-t1)+wait_time2(L3-t3)... +wait_time2(L3-t2), wait_time2(L3-t1)+wait_time2(L3-t2)+wait_time2(L3-t3)…, the information collected at intervals by the second sensor device 430 corresponding to the grounding line L3 is received (the time duration for the second sensor device 430 to collect information is ignored here), so that the time for the processing module 410 to obtain information from different second sensor devices 430 is more dispersed, preventing the second sensor devices of multiple grounding lines from sending information to the processing module 410 at the same time, causing data concurrency in the processing module 410.
