[0055] The cable discharge anomaly location device, method and equipment based on discharge pulse signal provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0056] Example 1

[0057] Figure 1 This is a schematic diagram of the cable discharge anomaly location device based on discharge pulse signals provided in Embodiment 1 of this application. Figure 1 As shown, it specifically includes the following:

[0058] The detection module 101 is disposed at at least two locations on the cable and is used to acquire discharge pulse signals;

[0059] The instruction control module 102, connected to the detection module, is used to issue detection instructions to at least two target detection modules when a discharge pulse signal is acquired.

[0060] The positioning calculation module 103 is used to determine the location of the discharge anomaly based on the time when the target detection module detects the discharge pulse signal and the setting position of the target detection module in the cable.

[0061] Firstly, this solution can be implemented in scenarios involving discharge detection and real-time monitoring of electrical wires and cables. Specifically, acquiring information on the location of abnormal discharges can be performed by intelligent terminal devices, such as smart terminals, or by an Internet of Things (IoT) system.

[0062] Based on the above usage scenarios, it is understood that the executing entity of this application can be the smart terminal device or the Internet of Things system, without further limitations.

[0063] In this solution, the detection module 101 is mainly used to acquire pulse signals. At least two detection modules are installed on the cable, dividing the cable into three sections: one end of the first detection module, the middle section between the two detection modules, and one end of the second detection module. A pulse signal can be a discrete signal with a certain periodicity. Specifically, a pulse signal is a brief, pulsating electrical impulse, similar to a heartbeat, frequently used in electronics. Its main characteristics include waveform, amplitude, width, and repetition frequency. A pulse is a signal that occurs for a short time within the entire signal cycle, unlike a continuous signal, with no signal for most of the cycle. Nowadays, it generally refers to digital signals, which have a signal for half the time within a cycle. In this solution, a pulse signal is generated when the cable discharges abnormally. The detection module is mainly used to detect whether the cable is discharging abnormally. Typically, partial discharge is accompanied by charge migration, which can generate a pulse current in the peripheral measurement circuit. By detecting the signal of this pulse current, the partial discharge can be measured.

[0064] A cable is a device for transmitting electrical energy or signals, typically composed of several or groups of conductors. Specifically, cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, and aluminum alloy cables, among others. They are all composed of single or multiple strands of conductors and insulation layers, used to connect circuits and electrical appliances. Cable laying methods vary depending on the location and environment; they can be buried underground or erected in the air. The signal transmitting end is positioned and energized, and then configured, such as by selecting the signal waveform, pulse width, and repetition period.

[0065] In this scheme, the command control module 102 is connected to the detection module 101. The detection command can be an instruction issued by the control command module to the detection module. Specifically, when the detection module detects a pulse signal, it sends feedback to the command control module. The command control module then issues detection commands to both detection modules. The detection commands specify the information that the detection modules need to acquire.

[0066] In this scheme, the timing of the discharge pulse signal can be the time when the detection module receives the pulse signal. Specifically, by comparing the detection times obtained by the two detection modules and their respective positions, the location of the discharge anomaly can be determined. For example, detection module 1 is located on the right, and detection module 2 is located on the left. Assume the propagation time of the pulse signal between the two detection modules is 5 seconds. If detection module 1 receives the pulse signal at 10:00:00 and detection module 2 receives the pulse signal at 10:00:05, the signal location can be determined to be to the left of detection module 1. The location of the discharge anomaly can then be determined based on the position of detection module 1.

[0067] In this embodiment, a detection module is disposed at at least two locations on the cable to acquire discharge pulse signals; a command control module is connected to the detection module and is used to issue detection commands to at least two target detection modules when a discharge pulse signal is acquired; a positioning calculation module is used to determine the location of the discharge anomaly based on the time when the target detection module detects the discharge pulse signal and the location of the target detection module in the cable. By calculating the arrival time of the pulse signal using the above-described cable discharge anomaly positioning device based on discharge pulse signals, the location of the discharge anomaly can be determined, further improving detection efficiency.

[0068] Example 2

[0069] Figure 2 This is a schematic diagram of the cable discharge anomaly location device based on discharge pulse signals provided in Embodiment 2 of this application. This solution makes a further improvement on the above embodiment, specifically: the instruction control module is specifically used for: determining the number of the detection module that acquired the discharge pulse signal when a discharge pulse signal is acquired; determining at least two target detection modules on the same side as the detection module that acquired the discharge pulse signal, based on the number of the detection module and a pre-determined mapping relationship between the setting position and number of the detection modules; and issuing detection instructions to the at least two target detection modules. Figure 2 As shown, it specifically includes the following:

[0070] The detection module 101 is disposed at at least two locations on the cable and is used to acquire discharge pulse signals;

[0071] The instruction control module 102, connected to the detection module, is used to issue detection instructions to at least two target detection modules when a discharge pulse signal is acquired.

[0072] The positioning calculation module 103 is used to determine the location of the discharge anomaly based on the time when the target detection module detects the discharge pulse signal and the setting position of the target detection module in the cable.

[0073] Specifically, the instruction control module is used for:

[0074] If a discharge pulse signal is acquired, determine the number of the detection module that acquired the discharge pulse signal;

[0075] Based on the number of the detection module and the mapping relationship between the predetermined setting position and number of the detection module, at least two target detection modules on the same side of the detection module that acquires the discharge pulse signal are determined.

[0076] Detection commands are issued to the at least two target detection modules.

[0077] In this scheme, the instruction control module sends detection instructions to the detection module. The detection module's number can be an ID (Identity Document) number, a unique identifier for each detection end. Specifically, the detection module needs to provide its own number. The number determines the detection module's location information and the information of the detection modules at both ends of the detection module. The mapping relationship can be a definite correspondence from one set to another. In this scheme, the data setting the location information is placed in one set, and the data setting the number is placed in another set. When one piece of information is obtained, the corresponding information is obtained. For example, if the number of detection module 2 is 002, the instruction control module finds the number of detection module 1 (left end of detection module 2) as 001 and the number of detection module 3 (right end of detection module 2) as 003 from the set. After obtaining the location and number, the instruction control module sends detection instructions to the two found detection modules.

[0078] In this solution, optionally, the instruction control module is specifically used for:

[0079] Determine the discharge intensity of the discharge pulse signal;

[0080] The interval between at least two target detection modules is determined based on the intensity.

[0081] Based on the interval distance, at least two target detection modules are identified from the same side of the detection module that acquires the discharge pulse signal.

[0082] In this scheme, the command control module sends a detection command to the detection module. Specifically, the command may require the detection module to provide feedback on the discharge intensity of the pulse signal. The discharge intensity can be the current intensity of the pulse signal discharge. Specifically, the detection module acquires the discharge current at a certain moment. For example, when the detection module receives the pulse signal, it detects that the current at that instant is 1000mA and feeds this data back to the detection module. The distance between the two target detection modules is then determined by comparing the discharge intensities. Generally, the greater the discharge intensity, the more proportional it is to the distance of the pulse signal. A greater discharge intensity indicates a closer distance. By judging the signal strength of the two detection modules, the distance between each module and the location of the discharge anomaly can be calculated, thus determining the distance of the discharge anomaly to one side and locating its position. For example, if detection module 1 acquires a discharge intensity of 1000mA and detection module 2 acquires an intensity of 200mA, the distance from detection module 1 to the discharge anomaly location can be calculated to be 50 meters, and the distance from detection module 2 to the discharge anomaly location can be 100 meters. Therefore, it can be determined that a discharge anomaly exists 50 meters to the left of detection module 1.

[0083] In this scheme, the distance between the discharge signal and the interval is determined by obtaining the discharge signal intensity, which can quickly locate the distance and discharge of the abnormal discharge location, further improving the detection efficiency.

[0084] In this embodiment, improvements are made to the above embodiments. Specifically, the instruction control module is used to: determine the number of the detection module that acquired the discharge pulse signal when a discharge pulse signal is acquired; determine at least two target detection modules on the same side as the detection module that acquired the discharge pulse signal based on the number of the detection module and a pre-determined mapping relationship between the setting position and number of the detection modules; and issue a detection instruction to the at least two target detection modules. This method of quickly determining the detection module information at both ends using information from one detection module, and spreading from one point to both sides, improves detection efficiency and reduces latency during the detection process.

[0085] Example 3

[0086] Figure 3 This is a schematic diagram of the cable discharge anomaly location device based on discharge pulse signals provided in Embodiment 3 of this application. This solution makes a further improvement on the above embodiment, specifically: the location calculation module is specifically used for: determining the theoretical time difference between the same pulse signal detected by the target detection module based on the setting position of the target detection module in the cable; judging the detected measured signals as the same pulse signal based on the theoretical time difference; and, if the signals are judged to be the same pulse signal, determining the location of the discharge anomaly based on the setting position of the target detection module in the cable. Figure 3 As shown, it specifically includes the following:

[0087] The detection module 101 is disposed at at least two locations on the cable and is used to acquire discharge pulse signals;

[0088] The instruction control module 102, connected to the detection module, is used to issue detection instructions to at least two target detection modules when a discharge pulse signal is acquired.

[0089] The positioning calculation module 103 is used to determine the location of the discharge anomaly based on the time when the target detection module detects the discharge pulse signal and the setting position of the target detection module in the cable.

[0090] Specifically, the positioning calculation module is used for:

[0091] Based on the placement of the target detection module in the cable, the theoretical time difference between the detection of the same pulse signal by the target detection module is determined;

[0092] The measured signals detected are judged to be the same pulse signal based on the theoretical time difference.

[0093] If the signal is determined to be the same pulse signal, the location of the discharge anomaly is determined based on the position of the target detection module in the cable.

[0094] In this solution, the positioning calculation module determines the theoretical time difference between pulse signals based on the placement of the detection modules within the cable. Specifically, the pulse signal velocity can be calculated using the time interval and distance between the two previous detection modules. This velocity can be calculated through multiple measurements, categorized, and saved as different pulse signals and their corresponding velocities. When a pulse signal is received again at that point, the historical pulse velocity at that point is retrieved to calculate the theoretical time. If the actual time matches the theoretical time, the signal is considered the same pulse signal. The location of the same pulse signal should also be identical; the location of this pulse signal, i.e., the location of the discharge anomaly, can be determined by retrieving historical pulse signal locations.

[0095] In this solution, optionally, the positioning calculation module is specifically used for:

[0096] If the signals are determined to be the same pulse signal, the waveform of the pulse signal is judged to meet the recognition conditions.

[0097] If the identification conditions are met, the location of the discharge anomaly is determined based on the placement of the target detection module in the cable.

[0098] In this scheme, the pulse signal waveform can be converted into a graphic, specifically including rectangular waves, sawtooth waves, triangular waves, spike waves, and stepped waves. The waveform of the historical pulse signal at that point is compared with the currently detected pulse waveform. If they match, it can be determined that the locations of the two pulse signals should also be consistent, i.e., the locations of the discharge anomalies are the same.

[0099] In this embodiment, waveform analysis can determine whether the current discharge anomaly is the same as a historical discharge anomaly. If they are the same, the location of the historical discharge anomaly can be retrieved, which can quickly locate the position of the discharge anomaly and further improve the detection efficiency.

[0100] In this embodiment, improvements are made to the above embodiment. Specifically, the positioning calculation module is used to: determine the theoretical time difference between the same pulse signal detected by the target detection module based on the setting position of the target detection module in the cable; determine whether the detected measured signals are the same pulse signal based on the theoretical time difference; and, if the signals are determined to be the same pulse signal, determine the location of the discharge anomaly based on the setting position of the target detection module in the cable. By calling historical data to determine the location of the discharge anomaly, the location of the discharge anomaly can be quickly located, further improving detection efficiency.

[0101] The cable discharge anomaly location device based on discharge pulse signals in this application embodiment can be a device, or a component, integrated circuit, or chip in a terminal. The device can be a mobile electronic device or a non-mobile electronic device. For example, mobile electronic devices can be mobile phones, tablets, laptops, PDAs, in-vehicle electronic devices, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, or personal digital assistants (PDAs), etc., while non-mobile electronic devices can be servers, network attached storage (NAS), personal computers (PCs), televisions (TVs), ATMs, or self-service machines, etc. This application embodiment does not impose specific limitations.

[0102] The cable discharge anomaly location device based on discharge pulse signals in this application embodiment can be a device with an operating system. This operating system can be Android, iOS, or other possible operating systems; this application embodiment does not specifically limit it.
