Description

Technical Field

[0001] The present invention relates to the technical field of cable fault management, and particularly to an intelligent instantaneous positioning method based on overhead cable faults. Background Art

[0002] An overhead cable is a power or communication transmission line suspended in the air through support facilities such as utility poles. It has the advantages of relatively simple construction and maintenance, and low cost. The overhead cable can adapt to different geographical environments and climatic conditions, and is widely used in the construction of urban and rural power grids and the communication field.

[0003] The invention patent with the application number 201510012738.4 discloses a fault location system based on transient quantity signals of an overhead cable hybrid line, which is characterized in that the system consists of two parts: a data center platform and a fault section location host module; the data center platform exchanges data with the fault section location host module through a server; the fault section location host module is also connected to several wireless acquisition processors; each wireless acquisition processor is provided with a trigger channel connected to the cable position and a corresponding channel to the trigger channel connected to the overhead position; the trigger channel and its corresponding channel are used to monitor the signals output by a pair of signal acquisition transformers respectively arranged at the cable and overhead line ends; when T < 0 and (M / v) < T < (M / v + t) is satisfied, a transient fault signal is generated at the overhead position of the corresponding channel of the trigger channel; when T > 0 and (M / v) < |T〈(M / v + t) is satisfied, a transient fault signal is generated at the cable position of the trigger channel; when T < (M / v) is satisfied, a transient fault signal is generated in the area between the trigger channel and the corresponding channel of the trigger channel: when |T| > (M / v + t), the trigger signal is invalid; where M is the interval between the monitoring points at both ends of the cable: is the range of the difference in trigger times of the two channels at both ends of the wireless data acquisition processor, T = T1 - T2: T1 is the trigger time of the trigger channel: T2 is the trigger time of the corresponding channel of the trigger channel: t is the trigger response time threshold of the wireless acquisition processor; v is the propagation speed of the traveling wave in the cable.

[0004] This application aims to solve the problem of "in order to switch on the reclosing under the preconditions of equipment safety and reliability after some instantaneous faults occur, it is necessary to be able to locate whether the fault occurs in the overhead section or the underground high-voltage cable section, so as to shorten the fault power outage time, reduce economic losses; and improve the efficiency of troubleshooting".

[0005] At present, the fault instantaneous positioning technology of overhead cables has not been innovated for a long time;

[0006] Therefore, we propose an intelligent instantaneous positioning method based on overhead cable faults. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the prior art, the present invention provides an intelligent instantaneous positioning method based on overhead cable faults, which solves the technical problems raised in the above-mentioned background technology.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] An intelligent instantaneous positioning method based on overhead cable faults, comprising:

[0010] Determine the overhead cable fault monitoring target, deploy sensor equipment on each overhead cable, and perceive the operating status information of the overhead cable in real time based on the sensor equipment; build a cloud database, use the cloud database to receive and store the operating status information of the overhead cable perceived by the sensor equipment; retrieve the operating status information of the overhead cable in the cloud database, and use the operating status information of the overhead cable to analyze the current operating fault risk of the overhead cable; obtain the current operating fault risk analysis results of the overhead cable, create a rolling directory representing the current operating fault risk of the overhead cable, and sort the labels of each overhead cable in the rolling directory based on the operating fault risk according to the current operating fault risk analysis results of the overhead cable; configure the display panel, receive the rolling directory in real time through the medium or wireless network, and always iterate the currently displayed rolling directory on the display panel with the newly received rolling directory; set the fault judgment threshold, and compare the fault judgment threshold with the latest analyzed current operating fault risk analysis results of the overhead cable to determine whether the overhead cable has a fault; receive the overhead cable fault alarm in real time, and use the overhead cable segment corresponding to the first group of overhead cable labels in the leading position of the latest rolling directory under the receiving overhead cable fault alarm state as the cable fault judgment target, and simultaneously obtain the location information of the judgment target.

[0011] Furthermore, when determining the overhead cable fault monitoring target, the overhead cables are separated based on the nodes connecting each other to obtain a plurality of groups of overhead cable segments, and each group of overhead cable segments is used as the monitoring target and the deployment target of the sensor equipment. Two groups of sensor equipment are deployed on each group of the overhead cable segments, and the two groups of sensor equipment are respectively deployed at both ends of the overhead cable segment. The sensor equipment consists of a traveling wave sensor, a temperature sensor, a current sensor, a voltage sensor, a vibration sensor and a locator.

[0012] When the sensor device senses the operating status information of the overhead cable, the sensor device is synchronously configured with the sensing logic, and the sensor device senses the operating status information of the overhead cable based on the sensing logic.

[0013] Furthermore, the perception logic is expressed as:

[0014]

[0015] Where: t nextis the next operating cycle of the sensor device; t0 is the initial operating cycle of the sensor device; U MIN ,I MIN To obtain t next The minimum voltage and current sensed by the previous sensor device during its operation cycle; U MAX ,I MAX To obtain t next The maximum voltage and current sensed by the sensor device during the previous operation cycle;

[0016] The sensing module runs at least three times in each operation cycle, and the operating time intervals of the sensing module in the same operation cycle are equal. When the sensing module runs for the first time, it runs based on the initial operation cycle t0 of the sensing device. The next operation cycle t next When first obtained, U MIN ,I MIN , U MAX ,I MAX All from t0, the next operation cycle of the sensor device t next In the second calculation, U MIN ,I MIN , U MAX ,I MAX All come from the next operating cycle t of the sensor device obtained last time next And so on, so that each operation of the perception module applies a new operation cycle.

[0017] Furthermore, when the cloud database stores the operating status information of the overhead cable, the stored operating status information of the overhead cable is synchronously marked based on the deployment location information and perception time of the source sensor equipment, and then the deployment location information and perception time of the sensor equipment marked with the overhead cable operating status information are used to identify the overhead cable operating status information originating from the same overhead cable segment and the same operating cycle, and the overhead cable operating status information is differentiated and stored according to the identification result.

[0018] Furthermore, when retrieving the operation status information of the overhead cables in the cloud database, the operation status information corresponding to the overhead cables with the shortest operation cycle of the equipment currently configured on the overhead cables is taken as the priority to be retrieved;

[0019] It is set that each time a retrieval operation is performed, the retrieved overhead cable operation status information comes from the same partitioned storage interval, and it is set that each time an overhead cable current operation fault risk analysis operation is performed, the retrieval operation is performed no less than six times, and among the retrieved overhead cable operation status information, half of the overhead cable operation status information carries one same sensor equipment deployment location information mark, and the other half of the overhead cable operation status information carries another same sensor equipment deployment location information mark, and the two sensor equipment deployment location information marks come from the same overhead cable segment.

[0020] Furthermore, after each completion of the analysis operation of the overhead cable current operation fault risk, the analysis operation is synchronously refreshed and executed, and the analysis results of the overhead cable current operation fault risk are continuously output. The analysis logic of the overhead cable current operation fault risk is expressed as follows:

[0021]

[0022] Where: k is a set of overhead cable operation status information representing the corresponding overhead cable segment operation failure risk of different storage intervals; To distinguish the mean value of the voltage-current product contained in the operation status information of each group of overhead cables in the storage interval, that is, the mean electric power; (p max -p min ) a To distinguish the difference between the maximum vibration frequency and the minimum vibration frequency at one end of the overhead cable segment in the storage area; (p max -p min ) b is the difference between the maximum vibration frequency and the minimum vibration frequency at the other end of the overhead cable segment in the storage interval; γ is the correction factor; K is the operational failure risk of the overhead cable segment; n is the set of operating cycles; k i The operation failure risk of the corresponding overhead cable section represented by the operation status information of the overhead cable stored in the corresponding storage interval in the i-th operation cycle;

[0023] in, Table pair The correction factor γ takes the value of 1 or -1, (p max -p min ) a >(p max -p min ) b When the correction factor γ = -1, (p max -p min ) a ≤(p max -p min ) b When , the correction factor γ=1.

[0024] Furthermore, the greater the operating failure risk K of the overhead cable segment, the greater the possibility that the overhead cable segment has a hidden danger of failure, and vice versa, the smaller the possibility that the overhead cable segment has a hidden danger of failure;

[0025] The more operating cycles the set n of operating cycles used in formula (2) contains, the more accurate the operating failure risk K of the overhead cable segment is, and vice versa, the lower the accuracy is.

[0026] Furthermore, the scrolling catalog representing the current operation fault risk of the overhead cable is synchronously updated based on the output frequency of the overhead current operation fault risk analysis result, and the scrolling catalog representing the current operation fault risk of the overhead cable is composed of the same number of overhead cable labels as the number of overhead cable segments;

[0027] The overhead cable label is a virtual label. The format of the overhead cable label is composed of a long strip image block layer and a text layer. The text layer displays the location information of the sensor equipment deployed on the overhead cable segment corresponding to the overhead cable label. The image block layer is rendered in the entire scrolling directory as the background of the text layer, and the rendering color of the scrolling directory is the same color system. The closer the overhead cable label is to the front position in the scrolling directory, the higher the saturation of the long strip image block layer, and the later the overhead cable label is in the scrolling directory, the lower the saturation of the long strip image block layer.

[0028] Furthermore, when determining whether the overhead cable has a fault based on the fault determination threshold, that is, determining the faulty overhead cable section;

[0029] Receive overhead cable fault alarms in real time, and use the overhead cable segment corresponding to the first group of overhead cable labels in the leading position of the latest scrolling directory in the state of receiving overhead cable fault alarms as the cable fault determination target, that is, determine the faulty overhead cable segment;

[0030] The operations of receiving an overhead cable fault alarm include: dialing a cable fault alarm telephone number, and the overhead cable management backend staff setting that the current overhead cable has a fault.

[0031] Furthermore, after the faulty overhead cable segment is determined, the location information of the sensor equipment deployed on the overhead cable segment contained in the corresponding tag of the faulty overhead cable is further read.

[0032] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0033] The present invention provides an intelligent instantaneous positioning method based on overhead cable faults. During the execution of the method, various operating status information of the overhead cables is collected by sensing equipment, and the operating fault risks of the overhead cables are analyzed based on the collected operating status information of the overhead cables. Further, by setting a specific visualization logic, the faulty overhead cables are locked in real time, and finally the instantaneous positioning of the overhead cable faults is realized, which effectively maintains the operating safety of the overhead cables and brings effective stability maintenance and safety guarantee to the daily operation of the overhead cables.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention will be further described below in conjunction with the embodiments.

[0038] Embodiment 1:

[0039] An intelligent instantaneous positioning method based on overhead cable faults in this embodiment is as follows: Figure 1 As shown, the following steps are included:

[0040] Step 1: Determine the overhead cable fault monitoring target, deploy sensor equipment on each overhead cable, and perceive the operating status information of the overhead cable in real time based on the sensor equipment;

[0041] When determining the overhead cable fault monitoring target, the overhead cables are separated based on the connecting nodes between each other to obtain several groups of overhead cable segments. Each group of overhead cable segments is used as the monitoring target and the deployment target of the sensor equipment. Two groups of sensor equipment are deployed on each group of overhead cable segments. The two groups of sensor equipment are deployed at both ends of the overhead cable segment. The sensor equipment consists of traveling wave sensors, temperature sensors, current and voltage sensors, vibration sensors and locators.

[0042] When the sensor device senses the operating status information of the overhead cable, the sensor device is synchronously configured with the sensing logic, and the sensor device senses the operating status information of the overhead cable based on the sensing logic;

[0043] The perception logic is expressed as:

[0044]

[0045] Where: t next is the next operating cycle of the sensor device; t0 is the initial operating cycle of the sensor device; U MIN ,I MIN To obtain t next The minimum voltage and current sensed by the previous sensor device during its operation cycle; U MAX ,I MAX To obtain t next The maximum voltage and current sensed by the sensor device during the previous operation cycle;

[0046] The sensing module runs at least three times in each operation cycle, and the operating time intervals of the sensing module in the same operation cycle are equal. When the sensing module runs for the first time, it runs based on the initial operation cycle t0 of the sensing device. The next operation cycle t next When first obtained, U MIN ,I MIN , U MAX ,I MAX All from t0, the next operation cycle of the sensor device t next In the second calculation, U MIN ,I MIN , U MAX ,I MAX All come from the next operating cycle t of the sensor device obtained last time next In this way, each operation of the perception module applies a new operation cycle;

[0047] Step 2: Build a cloud database, and use the cloud database to receive and store the operating status information of the overhead cable sensed by the sensor equipment;

[0048] Step 3: retrieve the operating status information of the overhead cable from the cloud database, and use the operating status information of the overhead cable to analyze the current operating fault risk of the overhead cable;

[0049] Step 4: Obtain the current operation fault risk analysis results of the overhead cables, create a rolling directory representing the current operation fault risks of the overhead cables, and sort the labels of the overhead cables in the rolling directory based on the operation fault risks according to the current operation fault risk analysis results of the overhead cables;

[0050] A rolling catalog representing the current operation fault risk of the overhead cable is synchronously updated based on the output frequency of the current operation fault risk analysis result of the overhead cable, and the rolling catalog representing the current operation fault risk of the overhead cable is composed of the same number of overhead cable tags as the number of overhead cable segments;

[0051] The overhead cable label is a virtual label. The format of the overhead cable label is composed of a long strip image block layer and a text layer. The text layer displays the location information of the sensor equipment deployed on the overhead cable segment corresponding to the overhead cable label. The image block layer is rendered in the entire scrolling directory as the background of the text layer, and the rendering color of the scrolling directory is the same color system. The closer the overhead cable label is to the front position in the scrolling directory, the higher the saturation of the long strip image block layer, and the later the overhead cable label is in the scrolling directory, the lower the saturation of the long strip image block layer;

[0052] Step 5: Configuring the display panel to receive the scrolling directory in real time through the medium or wireless network, and always iterating the scrolling directory currently displayed on the display panel with the newly received scrolling directory;

[0053] Step 6: Set a fault judgment threshold, and compare the fault judgment threshold with the latest analysis result of the current operating fault risk analysis of the overhead cable to determine whether there is a fault in the overhead cable; receive the overhead cable fault alarm in real time, and use the first group of overhead cable labels corresponding to the overhead cable segment in the front position of the latest scrolling directory under the receiving overhead cable fault alarm state as the cable fault judgment target, and synchronously obtain the location information of the judgment target.

[0054] In this embodiment, by executing the steps of the method in the above embodiment, a new instantaneous positioning solution is provided for overhead cable fault positioning. While locating the fault of the overhead cable, this method can also globally and visually display the operating fault risks of each overhead cable segment in the overall overhead cable, which is beneficial for overhead cable management users to further carry out daily maintenance of the overhead cables.

[0055] Embodiment 2:

[0056] In terms of specific implementation, based on Example 1, this example refers to Figure 1The intelligent instantaneous positioning method based on overhead cable fault in Example 1 is further described in detail:

[0057] When the cloud database stores the operating status information of the overhead cable, the stored operating status information of the overhead cable is synchronously marked based on the deployment location information and perception time of the source sensor equipment, and then the deployment location information and perception time of the sensor equipment marked with the overhead cable operating status information are used to identify the overhead cable operating status information from the same overhead cable segment and the same operating cycle. According to the identification results, the overhead cable operating status information is differentiated and stored.

[0058] Through the above arrangement, further limited storage management processing is provided for the overhead cable operation status information sensed by the sensor equipment.

[0059] like Figure 1 As shown, when retrieving the operation status information of the overhead cable in the cloud database, the operation status information corresponding to the overhead cable with the shortest operation cycle of the equipment currently configured on the overhead cable is taken as the priority retrieval target;

[0060] It is set that each time a retrieval operation is performed, the retrieved overhead cable operation status information is sourced from the same partitioned storage interval; it is set that each time an overhead cable current operation fault risk analysis operation is performed, the retrieval operation is performed no less than six times; and among the retrieved overhead cable operation status information, half of the overhead cable operation status information is marked with one same sensor device deployment location information, and the other half of the overhead cable operation status information is marked with another same sensor device deployment location information, and the two sensor device deployment location information marks are sourced from the same overhead cable segment;

[0061] After each analysis of the current operation fault risk of the overhead cable is completed, it is refreshed and executed synchronously, and the current operation fault risk analysis results of the overhead cable are continuously output. The logic of the current operation fault risk analysis of the overhead cable is expressed as follows:

[0062]

[0063] Where: k is a set of overhead cable operation status information representing the corresponding overhead cable segment operation failure risk of different storage intervals; To distinguish the mean value of the voltage-current product contained in the operation status information of each group of overhead cables in the storage interval, that is, the mean electric power; (p max -p min ) a To distinguish the difference between the maximum vibration frequency and the minimum vibration frequency at one end of the overhead cable segment in the storage area; (p max -p min ) bis the difference between the maximum vibration frequency and the minimum vibration frequency at the other end of the overhead cable segment in the storage interval; γ is the correction factor; K is the operational failure risk of the overhead cable segment; n is the set of operating cycles; k i The operation failure risk of the corresponding overhead cable section represented by the operation status information of the overhead cable stored in the corresponding storage interval in the i-th operation cycle;

[0064] in, Table pair The correction factor γ takes the value of 1 or -1. max -p min ) a >(p max -p min ) b When the correction factor γ = -1, (p max -p min ) a ≤(p max -p min ) b When , the correction factor γ=1;

[0065] The greater the operating failure risk K of the overhead cable segment, the greater the possibility that the overhead cable segment has a hidden danger of failure. Conversely, the smaller the possibility that the overhead cable segment has a hidden danger of failure.

[0066] The more operating cycles the set n of operating cycles used in formula (2) contains, the more accurate the operating failure risk K of the overhead cable segment is, and vice versa, the lower the accuracy is.

[0067] In this embodiment, through the above settings, the current operating fault risk analysis logic of the overhead cable is further limited, providing further logical support for the execution of the steps of the method in Example 1, ensuring the position execution of the method steps in Example 1, and realizing instantaneous fault positioning and visual feedback of the overhead cable.

[0068] Embodiment 3:

[0069] In terms of specific implementation, based on Example 1, this example refers to Figure 1 The intelligent instantaneous positioning method based on overhead cable fault in Example 1 is further described in detail:

[0070] When determining whether the overhead cable has a fault based on the fault determination threshold, that is, determining the faulty overhead cable section;

[0071] Receive overhead cable fault alarms in real time, and use the overhead cable segment corresponding to the first group of overhead cable labels in the leading position of the latest scrolling directory in the state of receiving overhead cable fault alarms as the cable fault determination target, that is, determine the faulty overhead cable segment;

[0072] The operation of receiving an overhead cable fault alarm includes: dialing a cable fault alarm telephone number, and the overhead cable management backend staff setting that the current overhead cable has a fault;

[0073] After the faulty overhead cable segment is determined, the location information of the sensor equipment deployed on the overhead cable segment contained in the corresponding tag of the faulty overhead cable is further read.

[0074] Through the above settings, the steps of the method in Example 1 are further defined, and the contents of the faulty overhead cable section determination logic and the operation of receiving the overhead cable fault alarm in step 6 are further defined.

[0075] In summary, during the execution of the method in the above embodiment, various operating status information of the overhead cable is collected through sensor equipment, and the risk of overhead cable operating failure is analyzed based on the collected overhead cable operating status information. Further, by setting specific visualization logic, the faulty overhead cable is locked in real time, and finally the instantaneous positioning of the overhead cable fault is achieved, which effectively maintains the operating safety of the overhead cable and brings effective stability and safety protection to the daily operation of the overhead cable.
