Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment monitoring computers, and in particular to a feeder action recording method and a wave recording system, a control device, and a storage medium. Background Art

[0002] In the electrical field, electrical equipment is used in high-voltage environments. Failure to promptly maintain equipment failures may lead to unpredictable consequences. Therefore, existing electrical equipment needs to be monitored by a monitoring system, such as an existing recording system, which monitors electrical equipment by obtaining feedback current waveforms.

[0003] Among them, the electrical equipment takes the circuit breaker as an example. The driving element of the circuit breaker usually adopts an electromagnet. The DC power supply is used to energize or de-energize the electromagnet to drive the circuit breaker to perform the opening and closing actions. During each opening and closing action, the current of the circuit breaker coil will change, and this changing waveform contains extremely important information. During the operation of the circuit breaker, it can be divided into multiple action events. Different action events can reflect the core stroke, core jamming, coil status (such as whether there is a short-circuited turn), the status of the iron gate and valve connected to the core top rod, the auxiliary contact status of the opening and closing coil and the conversion time. Possible problems, such as the current waveform, can be reflected. By monitoring the feedback current, the staff can roughly understand the performance and working conditions of the circuit breaker, providing an effective auxiliary basis for the staff's maintenance.

[0004] However, at present, the number of electrical equipment such as circuit breakers in the power grid is very large and they are dispersed. If all electrical equipment is recorded and processed, a huge amount of data will be generated. A monitoring system with sufficient storage capacity needs to be deployed on site to meet the requirements. In addition, the monitoring load requirements of the monitoring system are high. Operation and maintenance personnel need to frequently maintain the monitoring systems in various areas, which is costly and difficult to ensure the real-time and reliability of the monitoring results. When the staff analyzes the recorded data later, the huge amount of data will also increase the workload of the staff, and the lack of directional analysis increases the risk of misjudgment by the staff. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a feeder action recording method and a recording system, a control device, and a storage medium, which simplifies the recording data and improves the directivity, reduces the system maintenance cost, improves the monitoring flexibility, facilitates the analysis and comparison of the staff, reduces the workload, and improves the accuracy of the judgment.

[0006] A feeder action recording method according to an embodiment of the first aspect of the present invention includes: acquiring and recording a sequence event file, wherein the sequence event file includes various action events of the equipment and the various action events are sorted according to the time axis; monitoring the feedback current, when the sudden change of the current is greater than the current sudden change threshold, recording the current to form recording data; saving the recording data and the sequence event file based on the time axis; acquiring a first control instruction, and selecting a corresponding action event in the sequence event file according to the first control instruction; querying the recording data of the corresponding time according to the selected action event, and outputting and displaying the recording data.

[0033] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0035] In the description of the present invention, “several” means one or more, “more” means more than two, “greater than”, “less than”, “exceed”, etc. are understood as not including the number itself, and “above”, “below”, “within”, etc. are understood as including the number itself.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0037] like Figure 1 , Figure 2As shown, the feeder action recording method is applied to a recording device 110 and a monitoring background 120, wherein the recording device 110 includes a data acquisition module, a data processing module and a data display module. There are multiple recording devices 110 and one recording device 110 can be used to collect and monitor data of one or more electrical devices. The monitoring background 120 can communicate with each recording device 110 in a region (district, town, city, province, country) through a network, so as to perform statistics and overall analysis on the data of each recording device 110.

[0038] Among them, a storage module is integrated in the data processing module, and the storage module can store large-capacity recording data, sequence event files, etc. The recording device 110 also includes a power module for power supply. The storage module can include a larger-capacity EMMC memory such as 8 / 16 / 64 / 128GB for storing data, ensuring that a large amount of data can be stored for a long time and supporting rapid retrieval and call of data.

[0039] There may be a variety of devices monitored by the data acquisition module. Taking the circuit breaker 150 as an example, the data acquisition module may include a data acquisition module and a monitoring module. The monitoring module may be a current sensor 130 installed in the DC feeder cabinet 140. The recording device 110 may be directly installed on the panel of the DC feeder cabinet 140, or may be installed by replacing the installation panel of the feeder cabinet as a whole. The current sensor 130 used in the monitoring module can accurately capture current data, with a sampling frequency of up to 4000 Hz and high accuracy. At the same time, the data acquisition module may be connected to a controller that controls the action of the circuit breaker 150, and obtain the control instructions issued by the controller to the circuit breaker 150, thereby obtaining a sequence event file.

[0040] The data processing module can adopt the Cortex-A7 core, use the LINUX system CPU processor and its auxiliary circuits, and the processor main frequency is as high as 800MHz;

[0041] The data display module can include display modules such as display screens, touch screens, and buttons for human-computer interaction. It can present an embedded QT graphical interactive interface. The display screen can present waveform images, trend curves and other information to help staff intuitively understand fault conditions and equipment status.

[0042] like Figure 2As shown, the current sensor 130 of the monitoring module can adopt the sampling method of the total current at the end of the coil of the inductive circuit breaker 150 (superimposed with the load current). The current sensor 130 is installed in the DC feeder cabinet 140. The wiring is simple and the installation is convenient. There is no need to wire the coil current of each circuit breaker 150 in each high-voltage chamber. After obtaining the total current signal, it can be distinguished according to the coil current characteristics of the circuit breaker 150 and the load current characteristics, and the load current is eliminated, and only the coil current is retained.

[0043] like Figure 3 As shown, a feeder action recording method according to an embodiment of the first aspect of the present invention includes:

[0044] S210, obtaining and recording a sequence event file, wherein the sequence event file includes each action event of the device and each action event is sorted according to the time axis;

[0045] S220, monitoring the feedback current, when the current mutation amount is greater than the current mutation threshold, recording the current to form recording data;

[0046] S230, saving the recorded wave data and the sequence event file based on the time axis;

[0047] S240, obtaining a first control instruction, and selecting a corresponding action event in the sequence event file according to the first control instruction;

[0048] S250. Query the recorded data of the corresponding time according to the selected action event, and output and display the recorded data.

[0049] Among them, action events can be recorded in the timeline with action timestamps and action event labels. The action timestamp can be a time point or a time period. In addition, action events occurring at different times in the same device can be the same or different. Different devices can have different action events or the same action events.

[0050] The feeder action recording method of the present invention obtains and records a sequence event file during the operation of the equipment. The sequence event file includes various action events of the equipment sorted by time axis during the operation. For the monitoring of the feedback current, it is not necessary to obtain the full amount of recording data. Only when the sudden change amount of the current is greater than the current sudden change threshold, the current is recorded to form the recording data. This can avoid full recording caused by regular load current waveform changes, generate worthless waveform files, and occupy key capacity.

[0051] The recorded data and sequence event files are then saved based on the timeline. When the staff needs to conduct query analysis, based on the node with sudden current changes, they can select the action event near the fault node in the sequence event file, and query the recorded data of the corresponding time through the action event. This can determine which action link of the equipment has a problem, which can serve as an auxiliary basis for maintenance by the staff. This design simplifies the recorded data and improves its directionality, reduces system maintenance costs, improves monitoring flexibility, facilitates analysis and comparison by the staff, reduces workload, and improves the accuracy of research and judgment.

[0052] like Figure 6 As shown, the device may be a circuit breaker, and the waveform data obtained during the operation of the circuit breaker may be as follows Figure 6 shown.

[0053] Phase 1: In the time period of t0 to t1, t0 is the moment when the circuit breaker is issued an opening and closing command, the circuit breaker coil is energized at t0, the current rises rapidly, and t1 is the moment when the iron core starts to move. Phase 1 can reflect the working and performance status of the circuit breaker coil;

[0054] Phase 2: During the time period t1 to t2, at t1, the coil current increases, and the iron core begins to accelerate under the action of electromagnetic force. When the current begins to decrease, at t2, it indicates that the iron core touches the load of the operating machine and stops moving. Phase 2 reflects whether the iron core movement is stuck or unstuck;

[0055] Stage 3: During the time period t2 to t3, when the iron core hits the closing lock device, the iron core stops moving or bounces briefly, and the current begins to increase, causing the opening spring to start opening.

[0056] Stage 4: During the period of t3-t4, stage 4 is the continuation of the action of stage 3. The current keeps increasing slowly and the breaking process continues.

[0057] Stage 5: In the time period of t4 to t5, the current is cut off at t4, and the current value drops rapidly to zero. In stage 5, the auxiliary switch is disconnected, an arc is generated and stretched at the auxiliary switch contact key, the arc voltage will rise rapidly, forcing the coil current to decrease rapidly, the contacts are completely separated, and the equivalent resistance between the contacts increases rapidly until the arc is completely extinguished.

[0058] In some embodiments of the present invention, each device has a one-to-one corresponding identity number, and the sequence event files and recorded broadcast data of different devices are matched with the identity number of the device and then stored in categories;

[0059] The feeder action recording method further includes:

[0060] The first control instruction includes a number selection instruction for the identity number, and the sequence event file and the recorded broadcast data of the corresponding device are obtained according to the number selection instruction.

[0061] Each device will produce data files, which include sequence event files. Sequence event files and recorded broadcast data can be saved in pairs with the device's identity number. The number selection instruction mainly records the number of the device selected by the user. When saving sequence event files and recorded broadcast data, an index can be established based on the sorting of the identity numbers and the name of the device, and the identity number can be mapped to a list of device names containing the identity number. Users can also make selections based on the list to efficiently match the sequence event files and recorded broadcast data of the required device. In addition, the content list of the sequence event files that meet the user's requirements can be displayed on the display screen, including action timestamps, action event descriptions, etc.

[0062] In some embodiments of the present invention, when the amount of the current mutation is greater than the current mutation threshold, recording the current to form the recording data includes:

[0063] When the sudden change in current is greater than the current sudden change threshold, the recording is processed with a sudden change time interval to form recording data, wherein the initial moment when the sudden change in current is greater than the current sudden change threshold is taken as the sudden change time point, and the sudden change time interval is composed of a first time interval before the sudden change time point and a second time interval after the sudden change time point.

[0064] At the moment when the current mutation amount just exceeds the current mutation threshold, it indicates that the equipment is abnormally operating at this time. Therefore, this time node is used as the mutation time point, and the first time interval before the mutation time point and the second time interval after the mutation time point are recorded to facilitate staff to analyze the cause of the fault. Specifically, the first time interval can be 3s, 4s, 5s, etc., and the second time interval can be 10s, 15s, etc.

[0065] In some embodiments of the present invention, in the step of obtaining the first manipulation instruction and selecting a corresponding action event in the sequence event file according to the first manipulation instruction includes:

[0066] Acquire a viewing time interval in the first control instruction, and acquire a plurality of action events located in the viewing time interval in the sequence event file based on the time axis according to the viewing time interval;

[0067] Selecting a corresponding action event according to the first control instruction, and obtaining a query timestamp of the selected action event;

[0068] The step of querying the recorded data of the corresponding time according to the selected action event includes:

[0069] According to the query timestamp, based on the time axis, the recorded data that meets the query requirements are searched in each recorded data.

[0070] After selecting the equipment to be viewed, the staff can set the required viewing time interval in the timeline. The staff can set the viewing time interval according to the time point of the sudden failure, or according to multiple action events of the equipment to be checked. After using the viewing time interval to obtain several action events located in the viewing time interval based on the timeline, the user can click to select the action events and view each action event one by one. After selecting the action event, the action timestamp of the action event will be obtained as the query timestamp. At this time, the query timestamp can be used to query the recorded data that meets the query requirements.

[0071] It is understandable that due to the difference in sampling frequency between the sequence event file and the recording data, there may be a millisecond-level deviation, so the query timestamp may not be completely consistent with the recording timestamp of the recording data. In some embodiments of the present invention, the recording data has a recording timestamp based on the time axis;

[0072] The step of searching for the recorded wave data that meets the query requirements in each recorded wave data based on the time axis according to the query timestamp includes:

[0073] Search each recorded wave data according to the query timestamp to determine whether there is recorded wave data, and the recorded wave timestamp of the recorded wave data is the same as the query timestamp;

[0074] If it exists, the recorded data is output as the recorded data that meets the query requirements;

[0075] If it does not exist, then in the viewing time interval, obtain the recording data whose recording timestamp is closest to the query timestamp as the recording data output that meets the query requirements.

[0076] This is equivalent to, when the query timestamp can query the recorded data with the same recording timestamp, then the recorded data will be output as the recorded data that meets the query requirements. At this time, the action timestamp of the action event selected by the staff and the recorded timestamp of the recorded data that meets the query requirements completely correspond. If after the query, it is found that there is no recorded data with the same recording timestamp as the query timestamp, then the recorded data with the closest recording timestamp to the query timestamp in the viewing time interval will be output as the recorded data that meets the query requirements. The viewing time interval is used here as a limitation to reduce the query load and control the rationality of the matched recorded data.

[0077] In some embodiments of the present invention, Figure 4 As shown, the feeder action recording method also includes:

[0078] S310, obtaining a second control instruction;

[0079] S320, selecting multiple action events of the same type occurring at different times on the same device according to the second control instruction;

[0080] S330, querying the recorded wave data of the corresponding time according to the selected multiple action events;

[0081] S340, comparing the waveform contents of the plurality of recorded wave data to form first comparison data.

[0082] The recorded data and sequence event files of each device are stored in the database. The staff can select multiple action events of the same type that occur at different times on the same device by inputting the second control instruction. Since the action events are the same, the waveform content can be used as an important reference basis. Multiple triggered recorded action events are used to analyze the fault problems of the equipment, and the first comparison data is formed and saved as an auxiliary basis for the staff's maintenance.

[0083] In some embodiments of the present invention, Figure 5 As shown, the feeder action recording method also includes:

[0084] S410, obtaining a third control instruction;

[0085] S420, selecting the same type of action events occurring on multiple different devices according to the third control instruction;

[0086] S430, querying the recorded wave data of the corresponding time according to the selected multiple action events;

[0087] S440, comparing the waveform contents of the plurality of recorded wave data to form second comparison data.

[0088] Specifically, Figure 7 , 8 As shown, the device may be a circuit breaker, and different circuit breaker switches a and circuit breaker switches b are in the same action event (opening is Figure 7 , closing the circuit breaker Figure 8 ) can form second comparison data, which can be specifically presented in a waveform diagram.

[0089] When the same action event occurs in different devices, the recorded data are roughly the same. Similarly, when a fault occurs, the recorded data formed by the same type of action events occurring in different devices can be compared, and the waveform content can be used as an important reference. Finally, the second comparison data is saved as an auxiliary basis for maintenance staff.

[0090] According to the recording system of the second embodiment of the present invention, Figure 2As shown, the feeder action recording method disclosed in any of the above embodiments is executed, and the recording system includes:

[0091] A data collection module 510 is used to obtain and record sequence event files;

[0092] The monitoring module 520 is used to monitor the feedback current. When the sudden change of the current is greater than the current sudden change threshold, the current is recorded to form recording data.

[0094] A query module 540 is used to obtain a first control instruction and select a corresponding action event in the sequence event file according to the first control instruction;

[0095] The display module 550 queries the recorded data of the corresponding time according to the selected action event, and outputs and displays the recorded data.

[0096] The recording system of the present invention implements the feeder action recording method disclosed in any of the above embodiments, simplifies the recording data and improves the directivity, reduces the system maintenance cost, improves the monitoring flexibility, facilitates the staff to analyze and compare, reduces the workload and improves the accuracy of the judgment.

[0098] The control device can be any intelligent terminal including a central computer, a remote device terminal computer, etc.
