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 state of an intelligent grounding wire based on Beidou high-precision positioning and multiple communication modes. Background Art

[0002] With the continuous development and complexity of power systems, the requirements for power supply system safety are also increasing. Among them, the connection status detection and monitoring of grounding wires has become a key link to ensure the stable operation of power facilities.

[0003] Commonly, sensors that continuously detect ground wires in real time can achieve high-precision and high-safety real-time detection. Such sensors can detect potential faults in a timely manner and ensure the safe operation of power equipment by continuously detecting and monitoring the status of ground wires. However, this method consumes relatively high computing resources, especially in large-scale deployments, which may lead to slow system response and increased maintenance costs.

[0004] On the other hand, if interval detection sensors are used, although it can save computing resource consumption and reduce system burden, its safety issues have aroused concern. Interval detection often cannot capture instantaneous faults in real time, which may cause maintenance personnel to fail to discover safety hazards in time and increase the risk of equipment failure. Therefore, under the current technical background, how to strike a balance between safety and computing resource consumption has become an important issue that needs to be solved in ground wire detection and monitoring technology.

[0061] Through the above accompanying drawings, specific embodiments of this application have been shown, and there will be more detailed descriptions hereinafter. These accompanying drawings and textual descriptions are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. Specific Embodiments

[0062] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. On the contrary, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims.

[0063] The detection method for the intelligent grounding wire state based on Beidou high-precision positioning and multiple communication methods provided by the embodiments of this application can be applied to such as Figure 1In the grounding detection system 100 shown. Among them, the grounding detection system 100 includes a processing module 110, multiple ground wires, and a plurality of first sensing devices 120 and a plurality of second sensing devices 130 connected to the processing module 110; each ground wire corresponds to a first sensing device 120 and a second sensing device 130; the first sensing device 120 is used to continuously detect the connection state of the corresponding ground wire, and the second sensing device 130 is used to intermittently detect the connection state of the corresponding ground wire. The above-mentioned grounding detection system 100 can be applied to a power supply system.

[0064] A power supply system refers to the entire network for power transmission and distribution that delivers electrical energy from a power plant to users (such as households, industrial enterprises, etc.). The power supply system can involve power generation equipment, substations, transmission lines, distribution systems, distribution equipment, and end-use electrical equipment.

[0065] Among them, power generation equipment can be, for example, generators, thermal power plants, nuclear power plants, hydropower stations, wind farms, and solar power generation systems, etc., which are used to convert various forms of energy (such as chemical energy, mechanical energy, nuclear energy, solar energy, etc.) into electrical energy. Substations can be, for example, step-up substations and step-down substations, which are used to increase the voltage of the electricity generated by the power plant to reduce energy losses during power transmission and reduce the voltage to a safe and usable level before the power reaches the user terminal. Transmission lines refer to high-voltage transmission lines (such as overhead lines and underground cables), which are used to transmit electrical energy from a power station over long distances to a substation or directly supply power to a user terminal. The distribution system includes distribution transformers, distribution lines, and distribution cabinets, etc., which are used to reduce the voltage and distribute electrical energy to end-users, such as households, commercial, and industrial facilities. Distribution equipment includes: circuit breakers, contactors, fuses, and distribution boards, etc., which are used to control and protect the power supply to ensure that the power can be cut off in case of a fault and maintain the safety of the system. End-use electrical equipment can include lighting equipment, electrical appliances, industrial machinery, and other electrical equipment, etc., which are used to receive and use electrical energy to complete various electrical operations.

[0066] In the power supply system, grounding wires are required in almost every link. In a substation, the equipment enclosures of power generation stations usually need to be grounded to ensure the safe operation of generators and prevent the risk of electric shock caused by electric leakage or electrical faults. In a substation, grounding wires are used for grounding transformers, switchgear, and other high-voltage equipment to avoid the generation of high voltages in case of equipment failures and protect the safety of personnel and equipment. On high-voltage transmission lines, grounding wires are also installed under railways and cables for lightning protection and static discharge prevention to prevent damage to the lines and equipment. In the distribution system, distribution transformers are usually connected to the ground through grounding wires to ensure the safety of equipment in case of short circuits or faults. The metal enclosures of distribution cabinets, switches, and sockets need to be connected to the grounding system through grounding wires to prevent electric leakage accidents. The enclosures of end-user equipment also must be grounded to ensure that current can be safely introduced to the ground in case of failures and reduce the risk of electric shock.

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

[0068] The processing module 110 can adopt a central processing unit, or it can also be other general-purpose processors, digital signal processors, application-specific integrated circuits, etc. The general-purpose processor can be a microprocessor or this processor can also be any conventional processor, etc. The steps of the method disclosed in combination with the invention can be directly embodied as being executed and completed by a hardware processor, or executed and completed by a combination of hardware and software modules in the processor.

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

[0070] The second sensing device 130 can adopt one of a voltage sensor, a current sensor, an infrared sensor, or an optoelectronic sensor to achieve interval detection.

[0071] When installing the first sensing device 120 and the second sensing device 130, it is necessary to ensure that the positions of the first sensing device 120 and the second sensing device 130 are close to the connection contacts of the grounding wire, so as to accurately monitor the grounding status.

[0072] It should be noted that the present application does not limit the specific hardware devices used for 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 grounding detection system 100, as long as the sensing device can achieve continuous detection of the first sensing device 120 and intermittent detection of the second sensing device 130.

[0074] In one embodiment, the grounding detection system 100 further includes a third sensing device 140 connected to the processing module 110. The third sensing device 140 is used to collect the contact resistance value at the corresponding connection contact of the grounding wire. The third sensing device 140 may be, for example, a grounding resistance measuring instrument or a micro-ohmmeter.

[0075] As Figure 2 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 is connected to the grounding component 220 through 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 be a hook shape, for example, and an elastic component is also provided on the hanging part. When the grounding wire 200 is hung on any device to be grounded in the power supply system through the hanging part of the hanging component 210, the device in the power supply system can be limited within the hanging part and clamped by the elastic component to prevent the device in contact with the hanging part from shifting, so that the grounding wire 200 is loosened from the device; the connecting part of the hanging component 210 can be in the shape of a long strip. One 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 far from the hanging part can be coated with an insulating material such as a silica gel pad 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. When receiving the detection instruction output by the processing module 110, the first sensing device is used to continuously detect the connection state of the grounding wire. And within a preset time period, when the connection states obtained by the first sensing device 120 all indicate that the hanging component 210 in the grounding wire remains connected, the first sensing device 120 is controlled to stop detecting. After waiting for an initial interval time period, the second sensing device 130 is used to detect the connection state of the grounding wire; and when the connection state obtained by the second sensing device 130 indicates that the hanging component 210 in the grounding wire 200 remains connected, based on the number of times that the connection state obtained by the second sensing device indicates that the grounding wire remains connected, the interval time period corresponding to the next detection by the second sensing device 130 is determined; after waiting for the interval time period, the second sensing device 130 is used to continue detecting the connection state of the hanging component 210 in the grounding wire. Moreover, the communication component 230 can send the connection states obtained by the first sensing device 120 and the second sensing device 130 to the processing module 110.

[0079] The communication component 230 also has the Beidou positioning function and can be combined with the Beidou satellite navigation system to achieve precise centimeter-level positioning of the grounding wire 200. Among them, the communication component 230 can be communicatively connected to the above-mentioned processing module 110, for example, through a 433MHZ wireless transmission method or a 4G Cat1 wide-area terrestrial mobile communication method. The first sensing device 120 and the second sensing device 130 can be communicatively connected to the communication component 230, for example, by using one of the Beidou short message communication and wide-area terrestrial mobile communication methods.

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

[0081] Exemplarily, the above-mentioned communication component 230 also supports adaptive power adjustment. The communication component 230 can dynamically adjust the current input by the external power supply according to the remaining battery power of itself, control the current within the range of 0.5A - 2A, and can achieve a charging efficiency of ≥90%, so as to realize the 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 methods is provided. In this embodiment, this detection method is exemplified by being applied to the processing module in the above-mentioned grounding detection system. It should be noted that this detection method can also be applied to the communication components included in the grounding wire in the above-mentioned grounding detection system, or applied to a system including a processing module and the communication components included in the grounding wire, and is implemented through the interaction between the processing module and the communication components included in the grounding wire. As Figure 3 shown, this detection method includes:

[0083] Step 302: For any grounding wire, use the first sensing device to continuously detect the connection state of the grounding wire.

[0084] In this embodiment, the processing module can generate a trigger detection instruction and send it to the first sensing device to control the first sensing device to start continuously monitoring the connection state of the grounding wire. The first sensing device, for example, 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 grounding wire is in a state of maintaining connection; when the Hall voltage value is less than the preset voltage value, at this time, it can be considered that the leakage current of the grounding wire becomes smaller, and at this time, the processing module can determine that the grounding wire is disconnected or has poor grounding.

[0086] Step 304: When, within a preset time period, the connection states obtained by the first sensing device all indicate that the grounding wire maintains connection, control the first sensing device to stop detecting, and after waiting for an initial interval time period, use the second sensing device to detect the connection state of the grounding wire.

[0087] If, within a preset time period, the connection states obtained by the first sensing device all indicate that the grounding wire maintains connection, it can be considered that the current connection state of the grounding 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 sensing device to control the first sensing device to stop detecting the magnetic field of the grounding wire and stop generating the Hall voltage value.

[0088] At the same time, the processing module can 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 state of the grounding wire.

[0089] The initial interval time period can be a preset time period, for example, it can be 20 ms.

[0090] Step 306: When the connection state obtained by the second sensing device indicates that the grounding wire maintains connection, determine the interval time period corresponding to the next detection of the second sensing device based on the number of times that the connection state obtained by the second sensing device indicates that the grounding wire maintains connection.

[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 may determine, based on the number n of times the connection status obtained by the second sensing device indicates that the ground wire remains connected, the interval duration to be waited after the nth detection by the second sensing device, and after waiting for the interval duration, control the second sensing device to perform the (n + 1)th detection.

[0092] It can be seen therefrom that the interval duration between any two detections by 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 duration is related to the magnitude of the number of times the connection status obtained by the second sensing device indicates that the ground wire remains connected.

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

[0094] The above detection method can first continuously detect the connection status of the ground wire using the first sensing device, and when the duration for which the ground wire continuously remains connected reaches the preset duration, is disconnected, or the risk of poor grounding is relatively small, switch to the second sensing device for interval detection to continue detecting the connection status of the ground wire, thereby avoiding continuously detecting the connection status of the ground wire for a long time, saving computing resources, and moreover, by introducing the interval duration and determining the interval duration for each detection based on the number of times the connection status obtained by the second sensing device indicates that the ground wire remains connected, the waiting time before each detection by the second sensing device can be made different, making the time when the second sensing device sends the detection result of the connection status of the ground wire to the processing module more dispersed, thereby preventing the second sensing devices of multiple ground wires from simultaneously sending detection information to the processing module at the same time, resulting in data concurrency at the processing module.

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

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

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

[0098] Determine the interval duration corresponding to the second sensing device based on the reference duration and the jitter duration.

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

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

[0101] Compare the value obtained by the multiplication with a preset reference duration. When the value of the preset reference duration is smaller, use the preset reference duration as the base duration; otherwise, use the value obtained by the multiplication as the base duration.

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

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

[0104] where wait_time1 represents the base duration; base_time represents the initial interval duration; attempt represents the number of times the connection status obtained by the second sensing device indicates that the ground wire 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, during the process where 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 of base_time * 2^attempt as the base 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 and base_time * 2^attempt is greater than max_backoff, the processing module can first use the smaller value of max_backoff as the base duration.

[0107] Based on a preset duration jitter range and the base duration, determine the jitter duration, including:

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

[0109] Use the value obtained by the multiplication 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] Among them, jitter represents the jitter duration, (10ms, 20ms) represents the duration jitter range, and wait_time1 represents the reference duration. The numerical range of the duration jitter range can be customized and adjusted to achieve the control of the length and dispersion of the interval duration.

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

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

[0115] wait_time2 represents the interval duration.

[0116] In this embodiment, the processing module can make the number of times the connection status indicating that the grounding wire remains connected obtained by the second sensing device gradually increase by taking the smaller value as the setting method of the reference duration. The extension of the reference duration is positively correlated with the increase in the number of times the connection status indicating that the grounding wire remains connected obtained by the second sensing device. When the number of times the connection status indicating that the grounding wire remains connected obtained by the second sensing device reaches a specific value, the reference duration is equal to the preset reference duration and remains unchanged. By introducing the duration jitter range, the interval duration becomes more random, making the time when the second sensing device sends the information of the grounding wire connection status detection to the processing module more dispersed, preventing data concurrency in the processing module.

[0117] In some alternative embodiments, the detection method further includes:

[0118] When the connection status obtained by the second sensing device indicates that the grounding wire is not connected, control the second sensing device to stop detecting, re-detect the connection status of the grounding wire using the first sensing device, and update the initial interval duration to obtain the updated interval duration;

[0119] When the connection status obtained by the first sensing device indicates again that the grounding wire remains connected within the preset duration, control the first sensing device to stop detecting, and after waiting for the updated interval duration, use the second sensing device to detect the connection status of the grounding wire again.

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

[0121] If, within the preset duration after the first sensing device restarts detection, the connection status obtained by the first sensing device indicates that the grounding wire remains connected, the processing module can consider that the connection status of the current grounding wire has returned to stability, 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 sensing device to control the first sensing device to stop detection, and update the initial interval duration to obtain an updated interval duration. After waiting for the updated interval duration, another trigger detection instruction can be generated and sent to the second sensing device to control the second sensing device to restart continuous monitoring of the connection status of the grounding wire.

[0122] In the above detection method, by flexibly switching between the first sensing device and the second sensing device, the monitoring strategy can be dynamically adjusted to ensure the real-time monitoring and reliability of the connection status of the grounding wire. This not only improves the efficiency and flexibility of grounding status monitoring but also ensures the timeliness of handling abnormal states. Moreover, each time the first sensing device and the second sensing device are switched for use, the initial interval duration can be updated to make the interval duration more random, so that the time when the second sensing device sends the detection result of the connection status of the grounding wire to the processing module becomes more dispersed, preventing data concurrency in the processing module.

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

[0124] Determining the number of times that the connection status obtained by the second sensing device during the previous detection indicates that the grounding wire remains connected;

[0125] Determining the numerical range that the number of times conforms to from a plurality of pre-set consecutive numerical ranges; the plurality of numerical ranges correspond to a plurality of update values one by one;

[0126] Based on the initial interval duration, adding the update value corresponding to the numerical range that the number of times conforms to to obtain the updated 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 that the connection status obtained by the second sensing device during the previous detection indicates that the grounding wire remains connected, and match this number of times with a plurality of pre-set numerical ranges, and each numerical range corresponds to an update value. Subsequently, based on the initial interval duration, adding the update value corresponding to the numerical range that the number of times conforms to to obtain the updated interval duration.

[0128] It should be noted that the larger the numerical range, the larger the corresponding update value. Through this setting, the initial interval duration for the grounding wire with a relatively small 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: less than 5 times, 5 to 20 times, and more than 20 times. The update value corresponding to the numerical range of less than 5 times is -10 ms, the update value corresponding to the numerical range of 5 to 20 times is 0 ms, and the update value corresponding to the numerical range of more than 20 times is 10 ms. 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 indicating that the grounding wire remains connected during the previous detection of the second sensing device, which is 60 times. At this time, the processing module can determine that the update value is 10 ms, and then add 10 ms to the initial interval duration to extend the waiting duration after switching the first sensing device to the second sensing device.

[0130] The above detection method can determine the magnitude of the risk of the grounding wire being disconnected or having poor grounding based on the number of times the connection status indicating that the grounding wire remains connected during the previous detection of the second sensing device, and extend or shorten the initial interval duration based on different risks, so as to increase the detection frequency of the grounding wire with a greater risk of disconnection or poor grounding and decrease the detection frequency of the grounding wire with a smaller risk of disconnection or poor grounding. This can not only save computing resources, but also make the interval duration more random, make the time when the second sensing device sends the detection result of the grounding wire connection status to the processing module more dispersed, and prevent data concurrency from occurring in the processing module.

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

[0132] When the connection status indicates that the grounding wire does not remain connected, obtain the coordinate information of the grounding wire and the contact resistance value collected by the third sensing device; the coordinate information is determined based on the Beidou satellite navigation system and the Beidou positioning function on the grounding wire;

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

[0134] As an example, the Beidou satellite navigation system includes multiple Beidou reference stations and a data processing system; the Beidou reference stations are pre-set within the scope of the power supply system, and the coordinate positions of these Beidou reference stations are known. They can receive the Beidou satellite signals of multiple Beidou satellites, and 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 reference stations, and other necessary information.

[0135] Furthermore, the Beidou reference station can receive Beidou satellite signals, and after demodulation processing, send them to the data processing system. The data processing system can analyze the signals received by each Beidou reference station to determine possible error sources: multipath effect: the signal reflection causes a time delay in the signal arrival; atmospheric delay: the influence suffered by the signal when passing through the atmosphere; positioning error: the accuracy limitation of the Beidou satellite navigation system itself, and finally 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 position information of the grounding wire.

[0137] It should be noted that the method for obtaining the coordinate information of the grounding wire in this application is not limited, as long as it can obtain the coordinate information of the grounding wire with centimeter-level high precision.

[0138] The preset standard position corresponding to the grounding wire is the grounding point set according to engineering design and safety specifications. If the grounding wire deviates from this standard position, it may cause the grounding wire to be disconnected or have poor contact, thus affecting the safety of the 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 a prompt message to a preset number of intelligent terminals. The intelligent terminals are used to display the prompt message to the maintenance personnel. The prompt message may include: alarm information: such as "Warning: The position of the grounding wire has deviated and reached the contact resistance threshold. Please check the grounding connection!"; the current coordinate information of the grounding wire and the actual value of the contact resistance; operation prompts required, such as "Check the physical connection of the grounding wire to ensure no damage" "Repair or reconfigure the grounding wire as soon as possible to restore it to the standard position and reduce the contact resistance", etc.

[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 the necessary data support and guidance for subsequent troubleshooting and rectification.

[0141] In one embodiment, as Figure 4As shown, a ground detection system 400 is provided. The ground detection system 400 is applied to the above power supply system. The ground detection system 400 includes a processing module 410, ground wires L1, L2, and L3 arranged 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. And at the installation locations of the ground wires L1, L2, and L3, there are respectively one corresponding first sensing device 420, one second sensing device 430, and one third sensing device 440. Among them, the ground wires L1, L2, and L3 in the substation respectively correspond to preset standard positions P1, P2, and P3. The initial interval duration corresponding to the second sensing device 330 is preset to 5 ms, the preset reference duration is set to 1000 ms, and the duration jitter range is set to (10 ms, 20 ms).

[0142] Specifically, for example, in the characteristic interface displayed on the terminal human-machine interaction interface, the staff issues a detection instruction to the processing module 310 by clicking on the pre-integrated virtual component. The processing module 310 then generates a trigger detection instruction and simultaneously sends it to the three first sensing devices 420 corresponding to the ground wires L1, L2, and L3 to control the first sensing devices 420 to start continuously monitoring the connection status of the corresponding ground wires.

[0143] For example, the information collected by the first sensing device 420 corresponding to the ground wire L1 indicates that the ground wire L1 is disconnected before the detection duration reaches the preset duration. At this time, the processing module 410 can obtain the coordinate information of the ground wire L1, and collect the contact resistance value at the connection contact corresponding to the ground wire L1 through the third sensing device corresponding to the ground wire L1. When the coordinate information of the ground wire L1 indicates that the ground wire 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 sensing device 420 can still continuously detect the connection status of the connection line L1, and when the connection status of the connection line L1 indicates that the ground wire L1 remains connected, the detection duration of the first sensing device 420 is re-timed.

[0144] In addition, based on the information continuously collected by the two first sensing devices 320 corresponding to the ground wires L2 and L3, the processing module 410 determines that the ground wires L1 and L2 have remained connected within a preset time duration. At this time, the processing module 410 can consider that the connection state of the ground wires 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 ground wires L2 and L3 to control the two first sensing devices 420 corresponding to the ground wires L2 and L3 to stop detecting. After waiting for the initial interval duration t1, the processing module 410 generates another trigger detection instruction and sends it to the second sensing devices 430 corresponding to the ground wires L2 and L3 to control the second sensing devices 430 corresponding to the ground wires L2 and L3 to start monitoring the connection state of the ground wires L2 and L3 at intervals.

[0145] As Figure 5 shown, for example, for the ground wire L2, before the second sensing device 430 corresponding to the ground wire L2 performs the second detection, the processing module 410 can calculate the reference duration wait_time1(L2 - t1) = min(5ms * 2^1, 1000ms) = 10ms based on the connection state indicating that the ground wire L2 remains connected 1 time obtained by the second sensing device 330, and randomly select a duration from the duration jitter range (10ms, 20ms), for example, 15ms. Further calculate the jitter duration jitter(L2 - t1) = 15ms * 10ms = 150ms. Finally, calculate the interval duration wait_time2(L2 - t1) = max(0, 150ms + 100ms) = 250ms. And further generate a trigger detection instruction and send it to the second sensing device 430 corresponding to the ground wire L2 after waiting for the interval duration wait_time2(L2 - t1) to control the second sensing device 430 corresponding to the ground wire L2 to perform the second connection state detection on the ground wire L2, and so on, calculate the interval duration wait_time2(L2 - t2) that the second sensing device 430 corresponding to the ground wire L2 needs to wait before performing the third detection, the interval duration wait_time2(L2 - t3) that needs to be waited before performing the fourth detection...

[0146] Similarly, for the ground wire L3, the second sensing device 430 corresponding to the ground wire L3 can calculate the interval duration wait_time2(L3 - t1) before performing the second detection, the interval duration wait_time2(L3 - t2) that needs to be waited before performing the fourth detection, the interval duration wait_time2(L3 - t3) that needs to be waited before performing the fifth detection...

[0147] Correspondingly, after switching the first sensing device 420 to the second sensing device 430, the processing module 410 can receive the information intermittently collected by the second sensing device 430 corresponding to the ground wire 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 intermittently collected by the second sensing device 430 corresponding to the ground wire L3 at wait_time2 (L3 - t1), wait_time2 (L3 - t1) + wait_time2 (L3 - t2), wait_time2 (L3 - t1) + wait_time2 (L3 - t2) + wait_time2 (L3 - t3)... (the duration of information collection by the second sensing device 430 is ignored here). Thus, the time for the processing module 410 to obtain information from different second sensing devices 430 is more dispersed, preventing the second sensing devices of multiple ground wires from sending information to the processing module 410 simultaneously at the same time, resulting in data concurrency at the processing module 410.
