Cables can be divided into energized cables for normal operation, returned cables, and faulty cables due to their working characteristics. Most cables are currently laid in cable shafts or underground spaces. Therefore, how to conduct anti-theft monitoring of different types of cables and different working spaces has become an important part of ensuring the safe and stable operation of power, communications and other facilities.

[0003] At present, the anti-theft monitoring of cables mainly focuses on single cable status monitoring, and can only issue an alarm when the cable has an obvious fault or is stolen. It is unable to quickly monitor subtle abnormalities in live cables. When returning or faulty cables, they are currently only stored, causing these cables to become easy targets for theft during idle or maintenance periods. All these have led to the inability to conduct comprehensive and accurate anti-theft monitoring of cables. In addition, the current anti-theft monitoring of cables usually adopts current traveling wave analysis technology, and its passive monitoring method cannot accurately lock the cable theft point, which greatly affects the accuracy of cable anti-theft monitoring. Therefore, there is an urgent need for a cable anti-theft monitoring method, device, equipment and storage medium to solve the defects of the existing technology. Summary of the Invention

[0070] A working well displacement index threshold is obtained, and the working well displacement index threshold is compared with the working well displacement index to determine a working well displacement monitoring result.

[0071] This embodiment reflects the mechanical disturbance changes of the work well through the work well vibration information, and then reflects the electrical state changes of the cable to be monitored through the traveling wave characteristic value and the number of traveling waves of the voltage signal, thereby integrating the mechanical disturbance changes of the work well and the electrical state changes of the cable to be monitored. It can provide accurate early warning and rapid feedback on abnormal conditions in the work well, reduce the blind spots of work well displacement monitoring, improve the accuracy and comprehensiveness of work well displacement monitoring, and thus improve the accuracy and comprehensiveness of cable theft prevention monitoring.

[0072] In an optional embodiment, the traveling wave characteristic value and the number of traveling waves generated by the voltage signal are determined based on the voltage signal, wherein V ω (i) is the i-th traveling wave eigenvalue generated by the voltage signal, n is the number of traveling waves generated by the voltage signal in the monitoring period t0 to t1, t0 to t1 is one monitoring period, and then the work well vibration information is obtained, including: amplitude and vibration displacement; the work well amplitude function A(t) is determined based on the amplitude, and the work well vibration displacement function D(t) is determined based on the vibration displacement; then the weight coefficient α of the work well amplitude function and the work well vibration displacement function, as well as the weight coefficient β of the traveling wave eigenvalue are obtained; then the work well displacement index is determined based on the work well amplitude function, the work well vibration displacement function and the work well vibration traveling wave eigenvalue, and the work well displacement index calculation formula is specifically as follows:

[0073]

[0074] Then obtain the working well displacement index threshold MDI τ , when the work well displacement index is greater than or equal to the work well displacement index threshold, that is, MDI ≥ MDI τ When the vibration occurs, the time and location of the work well vibration are recorded as the work well displacement monitoring result.

[0083] This embodiment can reflect the tiny mechanical vibrations in the underground space through the amplitude of the optical fiber vibration signal, and can be immune to the influence of the cable electromagnetic field, thereby accurately characterizing the vibration information of the underground space, and through the traveling wave correlation characteristic value and the traveling wave correlation characteristic quantity, the traveling wave propagation characteristics are used to reflect the electrical changes of the cable to be monitored, thereby integrating the vibration information of the underground space and the electrical changes of the cable to be monitored, and can comprehensively monitor the underground space of the cable and accurately judge intrusion and destruction events, thereby improving the accuracy and comprehensiveness of underground space vibration monitoring, thereby improving the accuracy and comprehensiveness of cable theft prevention monitoring.

[0084] In an optional embodiment, the optical fiber vibration signal amplitude is defined as FV(t), which represents the amplitude of the optical fiber vibration signal at time t. t0 to t1 is a monitoring period. The traveling wave correlation characteristic value V corresponding to the underground space vibration is obtained based on the voltage signal. s (j) and the number of traveling wave associated features m, namely V s (j) represents the jth traveling wave correlation eigenvalue generated by the voltage signal and related to the underground space vibration, and m represents the number of traveling waves related to the underground space vibration during the monitoring period; then the weight coefficient γ of the traveling wave correlation eigenvalue is obtained, and the traveling wave correlation eigenvalue of the underground space vibration is calculated by combining the traveling wave correlation eigenvalue and the number of traveling wave correlation characteristics. Then, the coefficient δ of the optical fiber vibration signal amplitude is obtained to calculate the underground space vibration index. The calculation formula of the underground space vibration index is as follows:

[0085]

[0086] Then obtain the underground space vibration index threshold USVI τ , and compared with the underground space vibration index threshold USVI τ And the size of the underground space vibration index USVI, when USVI ≥ USVI τ When the underground space vibration index is greater than or equal to the underground space vibration index threshold, it is judged that the underground space has been invaded or damaged, and the time and place of the underground space vibration are recorded as the underground space vibration monitoring result.

[0087] Step S104: Obtain the working type of the cable to be monitored, perform breakpoint monitoring on the cable to be monitored according to the working type of the cable to be monitored, and obtain a cable breakpoint monitoring result, wherein the working type of the cable to be monitored includes: live cable, returned cable and faulty cable.

[0088] In this embodiment, performing breakpoint monitoring on the cable to be monitored according to the working type of the cable to be monitored to obtain the cable breakpoint monitoring result specifically includes:

[0089] When the cable to be monitored is a live cable, performing breakpoint monitoring on the copper shielding layer of the live cable to obtain a cable breakpoint monitoring result;

[0090] When the cable to be monitored is a returned cable, a connectivity test is performed on the returned cable to obtain a cable breakpoint monitoring result;

[0091] When the cable to be monitored is a faulty cable, harmonic monitoring is performed on the faulty cable to obtain a cable breakpoint monitoring result.

[0092] This embodiment uses different methods of breakpoint monitoring for different working types of monitored currents, thereby fully considering the respective characteristics of live cables, returned cables, and faulty cables, avoiding the use of unnecessary monitoring means, and not only improving the overall efficiency of cable breakpoint monitoring, but also reflecting the cable breakpoint situation more accurately and comprehensively, improving the accuracy and comprehensiveness of cable breakpoint monitoring, thereby improving the accuracy and comprehensiveness of cable anti-theft monitoring.

[0093] In this embodiment, when the cable to be monitored is a live cable, the breakpoint monitoring of the copper shielding layer of the live cable is performed to obtain the cable breakpoint monitoring result, which specifically includes:

[0094] When the cable to be monitored is a live cable, a detection data packet is sent to the live cable, a test signal is applied to one end of the copper shielding layer of the live cable, and the other end of the copper shielding layer of the live cable is monitored for the presence of the test signal;

[0095] If it is detected that the test signal does not appear at the other end of the copper shielding layer of the live cable, the disappearance time and disappearance location of the test signal are recorded, and the cable breakpoint monitoring result is determined based on the disappearance time and disappearance location of the test signal.

[0096] This embodiment can adapt to the breakpoint monitoring of live cables in different states by sending detection data packets to the live cables, and then accurately monitor the operating status of the live cables by monitoring the test signals at both ends of the copper shielding layer of the live cables, so that the breakpoint monitoring results can be recorded and determined when an abnormality is detected in the test signal, effectively identifying subtle abnormal defects in the live cables, and accurately and timely monitoring the cable breakpoints, thereby improving the accuracy of cable breakpoint monitoring and making the final cable anti-theft monitoring more accurate.

[0097] In an optional embodiment, a detection data packet is sent to the live cable, and the detection data packet includes: a detection instruction, which can be set according to the specific working status, working environment, etc. of the live cable. Afterwards, a test signal can be applied to one end of the copper shielding layer of the live cable, and monitoring is performed at the other end of the copper shielding layer of the live cable to determine whether a test signal appears. If it is determined that no test signal appears, the time and place where the test signal disappears are recorded, the cable breakpoint monitoring result is determined, and corresponding live cable breakpoint alarm information is generated.

[0098] This optional embodiment can accurately control the operating status of the live cable by sending specific detection data packets to the live cable and monitoring the test signal at both ends of the copper shielding layer. When the test signal is abnormal, it can be recorded and an alarm message can be generated accordingly. This effectively overcomes the defect of the existing technology that it is difficult to quickly detect subtle abnormalities in the live cable, ensures that potential theft or hidden faults are discovered at the first time, effectively maintains the safety of the live cable, and reduces problems such as power supply interruptions caused by cable failures or theft. By recording the time and place when the test signal disappears, determining the cable breakpoint monitoring results, and generating corresponding live cable breakpoint alarm information, it is possible to quickly respond to and accurately locate abnormal conditions in the live cable. Once the test signal disappears, the live cable breakpoint alarm information can be generated based on time and place, allowing staff to quickly know the location of the breakpoint and conduct investigation and repair. This shortens the fault discovery and processing cycle, improves the reliability and stability of the power system, and reduces the risk of large-scale power outages caused by cable problems.

[0101] If any two phases of the core, copper shielding layer and armor layer of the returned cable are detected to be disconnected, the disconnection time and disconnection location are recorded, and the cable breakpoint monitoring result is determined based on the disconnection time and disconnection location.

[0102] This embodiment achieves effective breakpoint monitoring of the returned cable by short-circuiting and detecting the connectivity of the wire core, copper shielding layer and armor layer at one end of the returned cable. It can timely and accurately detect abnormal connection conditions of the returned cable, avoiding the risk of theft caused by lack of effective supervision of the returned cable, thereby making the final cable anti-theft monitoring more accurate.

[0103] In an optional embodiment, the core, copper shielding layer and armor layer are short-circuited at one end of the returned cable, and connectivity detection is performed on any two phases of the core, copper shielding layer and armor layer at the other end of the returned cable. If it is detected that any two phases of the core, copper shielding layer and armor layer of the returned cable are not connected, the time and place where the disconnection occurs are recorded as the cable breakpoint monitoring result, and then the returned cable breakpoint alarm information is generated based on the time and place where the disconnection occurs.

[0104] This optional embodiment achieves effective anti-theft monitoring of returned cables by detecting the short circuit and connectivity of the core, copper shielding layer and armor layer of the returned cables. It can promptly detect abnormal connections of the returned cables, avoiding the risk of the returned cables being stolen due to lack of effective supervision, and records the time and place of the disconnection as the cable breakpoint monitoring result when problems occur in the connectivity detection of the returned cables. Then, based on the time and place of the disconnection, a return cable breakpoint alarm information is generated, which enables staff to take corresponding measures to prevent the returned cables from being stolen or further damaged, effectively improving the safety and standardization of cable management.

[0105] In this embodiment, when the cable to be monitored is a faulty cable, harmonic monitoring is performed on the faulty cable to obtain a cable breakpoint monitoring result, specifically including:

[0108] This embodiment applies harmonic signals to the core and armor layer of one end of the faulty cable and performs harmonic monitoring at the other end of the faulty cable. The abnormal harmonic signals can be used to monitor the breakpoints and analyze the fault points of the faulty cable, thereby realizing anti-theft monitoring of the cable. The breakpoint locations are determined by monitoring the abnormal harmonics, providing an effective means for maintenance and anti-theft of the faulty cable, thereby making the final cable anti-theft monitoring more accurate.

[0109] In an optional embodiment, a DC12V power supply is installed on the core and armor layer of one end of the faulty cable so that a harmonic signal can be applied thereto, and then an anti-theft harmonic meter is installed at the other end of the faulty cable to perform harmonic monitoring. When an abnormal harmonic appears on the anti-theft harmonic meter, the abnormal harmonic signal is analyzed and the time and position of the breakpoint are recorded as the breakpoint time and position of the faulty cable, to obtain a cable breakpoint monitoring result, and generate a faulty cable breakpoint alarm information based on the cable breakpoint monitoring result.

[0110] In this optional embodiment, power supply installation, harmonic meter setting and harmonic monitoring operations are performed on the faulty cable, thereby realizing anti-theft monitoring and fault point analysis of the faulty cable. By monitoring abnormal harmonics to determine the breakpoint location and generate fault cable breakpoint alarm information, the faulty cable can be effectively maintained and theft-proofed, thereby improving the efficiency and safety of cable maintenance and reducing additional losses caused by the theft of the faulty cable.

[0111] In an optional embodiment, the staff injects a voltage signal into one of the phases A, B and C of the cable to be monitored, and then opens the phase, and then performs open-circuit calibration. After the calibration is completed, the open-circuit waveform will be displayed in the waveform acquisition area of the waveform acquisition device. Then, by adjusting the amplitude rotation button of the waveform acquisition device, the amplitude of the open-circuit waveform is adjusted to be consistent with or similar to the preset waveform amplitude threshold. Then, the amplitude rotation button is no longer adjusted, and the corresponding phase at the other end of the cable to be monitored is short-circuited to perform short-circuit calibration. After that, the waveform acquisition area will display the short-circuit waveform, and then the cursor will automatically be stuck at the waveform bifurcation point and the full length of the cable will be displayed at the same time. Then, the monitoring interval time is set. According to the set time, the current monitoring waveform and the current length will be displayed after one round of time. The staff can analyze the traveling wave of the voltage signal on the cable to be monitored by analyzing the monitoring waveform and its corresponding length to determine the breakpoint position of the live cable.

[0112] Step S105: determining the cable theft prevention monitoring result according to the work well displacement monitoring result, the underground space vibration monitoring result and the cable breakpoint monitoring result.

[0113] In an optional embodiment, if the work well displacement monitoring result is that the work well displacement index is less than the work well displacement index threshold, and the underground space vibration monitoring result is that the underground space vibration index is less than the underground space vibration index threshold, and the cable breakpoint monitoring result is none, it is determined that the cable anti-theft monitoring result is that the monitored cable has not been stolen during the monitoring period.

[0114] This embodiment injects a voltage signal into the cable to be monitored and collects the working well vibration information and underground space vibration information corresponding to the cable to be monitored, so as to calculate the working well displacement monitoring results and underground space vibration monitoring results corresponding to the cable to be monitored, and then performs breakpoint monitoring based on the working type of the cable to be monitored, and obtains the breakpoint monitoring results of the live cable, the returned cable and the faulty cable. Finally, the cable anti-theft monitoring results are determined through the working well displacement monitoring results, the underground space vibration monitoring results and the cable breakpoint monitoring results, thereby realizing comprehensive and accurate monitoring of cable anti-theft. The present invention monitors the working well and underground space where the monitored cable is located, and through working well displacement detection and underground space vibration monitoring, it can comprehensively monitor the underground space of the cable and accurately judge intrusion and destruction events, and then perform breakpoint monitoring in combination with the working type of the cable (live cable, returned cable, faulty cable), which can improve the accuracy of cable anti-theft monitoring. By integrating the working well displacement monitoring results, underground space vibration monitoring results and cable breakpoint monitoring results, it can achieve all-round monitoring of the cable path and its surrounding environment, can timely discover and deal with potential safety hazards, improve the overall effect of cable anti-theft monitoring, and effectively solve the problems of traditional cable anti-theft technology such as narrow monitoring range, untimely discovery and low accuracy, greatly improve the accuracy, comprehensiveness and timeliness of cable anti-theft monitoring, ensure the safe and stable operation of the cable in various states, reduce the economic losses and safety hazards caused by cable theft and cutting, and provide reliable technical support for cable protection in the power, communication and other industries.
