[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] According to one aspect of the present invention, a method for safety protection of substation secondary equipment operation is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0029] Figure 1 This is a flowchart of a substation secondary equipment operation safety protection method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0030] Step S102: Recognize the text information contained in the work order to obtain the text recognition result.

[0031] The aforementioned work order can be a document specifying relevant work information, such as an electronic work order or a paper work order. The aforementioned text information can be work-related text information within the work order, such as the work order number, substation name, work task, work location, safety measures, etc. The aforementioned text recognition result can be the specific text content obtained based on the aforementioned text information.

[0032] In an optional embodiment, considering the large workload and high labor costs associated with manually deploying protective devices to protect the substation's protective panels, this application reduces costs by automatically controlling the operating status of the protective components within the protective devices. To improve the accuracy of controlling the operating status of the protective components, the substation protection system (hereinafter referred to as the protection system) can first identify various text information on the work order to obtain text recognition results related to the operating status of the protective components. For example, the protection system first acquires a digital image of an electronic work order or a scanned paper work order, then segments the image into regions, uses automatic recognition technology to identify different regions in the work order, extracts characters and numbers from each region, and finally converts the text in the image into an editable text format to obtain the text recognition results of the work order.

[0033] For example, the protection system first uploads the electronic work order or scanned work order image to an OCR (Optical Character Recognition) system. The OCR system then performs preprocessing operations on the work order, such as denoising, grayscale conversion, and binarization, to improve the accuracy of recognizing the text information contained in the work order. After preprocessing, the preprocessed image can be segmented to identify different regions of the work order, such as the substation name, work task, work location, and safety measures, for more accurate character recognition later. After identifying these multiple regions, the protection system can then use OCR technology to extract character and number features from each region, including features such as shape, size, and position. Finally, based on the extracted features, a pre-trained machine learning algorithm model is used to recognize each character, converting the text in the image into an editable text format.

[0034] For example, the protection system can first use ICR (Intelligent Character Recognition) technology to automatically extract text information from the work order image. Then, it defines a set of rules to capture and parse this text information. These rules include, but are not limited to, regular expression rules, logical judgment rules, and error checking rules. Next, the openL Tablets rule engine is used to configure these rules. The preprocessed text data is input into the rule engine, which automatically identifies and extracts key information. Finally, the rule engine matches the information in the text based on the defined rules, thus obtaining the recognition result of the aforementioned text information.

[0035] Step S104: Based on the text recognition results, construct a text database that matches the work ticket identifier on the work ticket.

[0036] The aforementioned work order identifier can be information that facilitates the identification and management of work orders, such as a work order number or substation name, but is not limited to these. The work location for the secondary equipment area on the work order includes at least one or more of the following: in front of the screen, behind the screen, and both in front of and behind the screen, but is not limited to these. The aforementioned text database can be an entity or virtual electronic device that stores and manages the work order text information; for example, it can be a relational database, a non-relational database, or a server cluster.

[0037] In one optional embodiment, considering that the identified text recognition results are mixed in one interface and may be quite messy, when the work order contains a lot of text information, directly controlling the protection device to protect the substation secondary equipment (protection screen) based on the text recognition results may result in low screening efficiency and incorrect screening results when filtering text recognition results that match the work content of controlling the protection device. This leads to low efficiency in controlling the operation of the protection device based on the filtered text recognition results, or even failure to accurately control the operation of the protection device. Therefore, in order to improve the rationality of controlling the operation of the protection device based on the work order, after obtaining the above-mentioned text recognition results, the protection system can first build a standardized text database based on the text recognition results so that the protection system can obtain relevant parameters for controlling the operation of the protection device. Considering that different types of work orders may contain different text information, if the above text database is constructed according to a single database format, the constructed text database may be inaccurate. For example, text information may be filled into the wrong data field, causing the protection system to be unable to accurately determine the relevant parameters used to control the operation of the protection device. Therefore, when constructing the text database, the protection system can also determine the work order identifier of the work order, so as to determine a reasonable database format based on the work order identifier, and construct the above text database based on the text recognition results, thereby ensuring the rationality of the constructed text database.

[0038] To facilitate understanding, for example, the protection system can first classify the identified text results. Considering that when substation equipment malfunctions and staff need to repair it, or when routine inspections and maintenance are required, the repairs are primarily targeted at a specific area of ​​the substation, related to the specific work location included in the work order. Furthermore, considering that a single work order may contain multiple specific work locations, some of which may not be within the protection room, the protection system can first identify the information contained in the work order, such as the substation name, order number, work task, work location, and safety measures. Then, the protection system can focus on identifying the specific work locations within the work location and safety measures. For example, if the work location or safety measures contain at least one of the following descriptions: "*room*: *in front of screen" or "*room*: *behind screen," it indicates the work location is within the protection room. In this case, the protection system can classify the work order information according to the specific work location. Specifically, the protection system can categorize work locations or safety measures within the same work order with the specific work location "*room*: *screen in front" into Category 1, those with "*room*: *screen behind" into Category 2, and those with "*room*: *screen in front and behind" into Category 3. After this categorization, the storage structure of the constructed text database can be as follows: Substation name, ticket number, work task, work location category (*room*: *screen in front, *room*: *screen behind, *room*: *screen in front and behind), safety measure category (*room*: *screen in front, *room*: *screen behind, *room*: *screen in front and behind), where the asterisk "*" represents any character or string. To ensure reasonable storage during categorization, a database matching the work order identifier can be selected to store this information, thus constructing the aforementioned text database. In addition to matching with work order identifiers, the protection system can also directly use a database that meets actual needs. For example, a relational database can be used to store the above information to facilitate data operations such as querying, updating, and deleting work order information; a non-relational database can be used to facilitate real-time processing of large amounts of text data extracted by OCR; or a server cluster can be used to provide high availability and fault tolerance, thereby ensuring the stability of data and services. After selecting a suitable database and classifying the text recognition results, the protection system can further store the specific text recognition results, such as the name, location, and related security measures of the protection screen, into the database categories contained in the database, and arrange the information under each category according to logical relationships and order to reasonably construct the above-mentioned text database.

[0039] Step S106: Based on the data reading logic corresponding to the work order identifier, determine the device control parameters of the protection device from the text database. The protection device includes: at least one suspension component, the position of which corresponds to the position of the protection panel in the substation, and the suspension component is used to isolate the protection panel when it is in the deployed state.

[0040] The aforementioned data reading logic can refer to the logic capable of retrieving information from a text database based on different work order configurations. The aforementioned protective device can be a device used for isolating and protecting screens, such as a red curtain hanging device or an electronic red curtain, but is not limited to these. The aforementioned device control parameters can be data used to drive the operation of the aforementioned protective device.

[0041] In an optional embodiment, considering that the text database may store data related to multiple different work orders, the data read directly from the text database may not match the actual work content included in the work order, resulting in low accuracy of the device control parameters of the aforementioned device. Therefore, in order to improve the accuracy of data reading, the protection system can first determine the data reading logic corresponding to the work order identifier based on different work order identifiers. Then, the protection system can read the corresponding device control parameters of the protection device from the text database based on the data reading logic, so that the protection system can accurately control the aforementioned protection device according to the read device control parameters.

[0042] For example, the aforementioned protective device could be an automatic red curtain hanging device, preventing users from contacting the internal circuits of the substation's secondary equipment. When the work location on the work order points to the protection room and includes "in front of the screen," the protection system can determine the following data reading logic based on the work location: corresponding to the work location "in front of the screen" within the protection room, the hanging assembly of the red curtain hanging device is deployed behind that screen and in front of adjacent operating screens. Based on the above data reading logic, the device control parameters confirmed from the text database can be: a red cloth marked "Equipment in operation!" is deployed behind its screen and in front of adjacent operating screens. When the work location on the work order points to the protection room and includes "behind the screen," the protection system can determine the following data reading logic based on the aforementioned work location: corresponding to the work location "behind the screen" within the protection room, the hanging assembly of the red curtain hanging device is deployed in front of that screen and in front of adjacent operating screens. Based on the above data reading logic, the device control parameters confirmed from the text database can be: a red cloth marked "Equipment in operation!" is deployed in front of its screen and in front of adjacent operating screens. When the work location on the work order points to the protected room and includes "before and after the screen," the protection system can determine the following data reading logic based on the aforementioned work location: corresponding to the work location "before and after the screen" within the protected room, the suspension components of the red curtain hanging device are deployed in front of and behind the adjacent operating screen. Based on the above data reading logic, the device control parameters confirmed from the text database can be: deploying a red cloth marked "Equipment in operation!" in front of and behind its adjacent operating screen.

[0043] Step S108: Control the working state of the suspension assembly based on the device control parameters.

[0044] The aforementioned working state can be either deployed or retracted, but is not limited to these. In an optional embodiment, the protection system can obtain the device control parameters of the protection device based on the aforementioned text database and work order. These parameters can be synchronized by the protection system to an electronic device, which can be used to issue work instructions to the control system of the protection device in front of or behind the protective screen. The control system can adjust the working state of the suspension assembly based on the aforementioned work instructions.

[0045] For example, the control parameters of the above-mentioned device could be: to unfold a red cloth marked "Equipment in operation!" behind the protective screen and in front of the adjacent operating protective screen. This parameter can be verified by the protection system first. If the verification result shows that the parameter is consistent with the safety measures identified from the work order, the protection system can generate the control logic of the above-mentioned automatic red cloth curtain hanging device based on the parameter, and can send the above control logic to the tablet, so that the staff can intuitively see the current protective measures on the tablet, that is, which protective screens in the protection room have their red cloth curtains unfolded. Figure 2This is a schematic diagram of a tablet computer interface for a substation secondary equipment operation safety protection method according to an embodiment of the present invention, as shown below. Figure 2As shown, a substation button is displayed in the upper left corner of the tablet interface. Clicking this button will display a substation name information box, which shows the names of multiple substations. Clicking on one of the substation names will further display multiple work order numbers for that substation. These work order numbers indicate how many work orders related to secondary equipment are currently in progress at that substation. Clicking on one of the work order numbers will further display text information obtained from the work order recognition scan, such as the work task, work location, and safety measures. For example, the displayed work task could be "XX station remote motor data inspection," the displayed work location could be "XX station XX room 02: XX screen front," and the displayed safety measures could be "XX station XX room 02: XX screen front hangs a 'Working Here!' sign, and behind it and in front of the adjacent operating screen hangs a red cloth saying 'Equipment is running,'" or "XX station XX room 02: XX screen front hangs a 'Working Here' sign, and behind it and in front of the adjacent operating screen hangs a red cloth saying 'Equipment is running!'," or "XX station XX room 02: XX screen front hangs a 'Working Here' sign, and behind it and in front of the adjacent operating screen hangs a red cloth saying 'Equipment is running!'." It should be noted that the text content such as work tasks, work locations, and safety measures shown above are merely illustrative examples, and the specific details can be set by the staff themselves, without any limitations. Furthermore, in the substation name information box mentioned above, selecting a substation name will display a 3D image of the current substation's protection panel in the lower right corner of the interface, used to view the device control parameters of the current substation. When clicking on a specific work order number under that substation, the lower right corner of the interface can display only the device control parameters of the protection panel corresponding to that work order. At this time, the left side of the tablet interface will display the currently selected work order number, a "Confirm Deployment" button, and a "Work Complete" button. The staff can verify the accuracy of the currently selected work order number. If accurate, they can click "Confirm Deployment" on the tablet interface to issue instructions to the control system of the red curtain hanging equipment behind the protection panel and in front of the adjacent operating protection panels. The control system uses logical judgment to control the hanging components to unfold the red curtain. Once the work is completed, the staff can click the "Work Completed" button on the tablet interface. Considering that multiple work orders from the same workstation may point to the same work location, to prevent interference between these work orders during the red curtain retrieval process and potential omissions in the implementation of protective measures, the control system can perform logical verification on the control parameters of the aforementioned device. Specifically, completed work orders will continuously send a logic signal of 0 to the control system for the aforementioned work location, while other incomplete work orders will continuously send a logic signal of 1 to the control system for the same work location. When the status of a work order changes from incomplete to completed, the control system will invert the logic signal for that work order, changing it from a logic signal of 1 before completion to a logic signal of 0 after completion.When a worker clicks the "Work Complete" button, the control system performs a real-time OR operation on the logic signals at the aforementioned work location. If the OR operation result is 1, it indicates that the work at that location is not yet complete. In this case, the control system for the current work location temporarily does not control the suspension assembly to retract the red curtain. If the OR operation result is 0, it indicates that the work at that location is complete. In this case, the control system for the current work location can control the suspension assembly to retract the red curtain. Furthermore, workers can also adjust parameters such as the location and name of the protection panels in each substation using a tablet. It should be noted that the adjusted parameters can be updated in real-time on other tablets, meaning other workers can perceive the changes on their own tablets. This avoids complex information exchange between workers and reduces the cost of safety protection for substation secondary equipment operations.

[0046] It should be noted that the tablet computer mentioned above is only an example. Staff can choose mobile devices according to their actual needs, and no restrictions are imposed here.

[0047] In this embodiment of the invention, the text information contained in the work order is identified to obtain the text recognition result; based on the text recognition result, a text database matching the work order identifier is constructed; based on the data reading logic corresponding to the work order identifier, the device control parameters of the protective device are determined from the text database; and the working state of the suspension component is controlled based on the device control parameters. By automatically constructing a text database containing the work order text information based on the work order, and obtaining accurate device control parameters based on the constructed text database, the working state of the suspension component in the protective device is automatically controlled according to the device control parameters. This improves the placement efficiency of the suspension component while ensuring the accuracy of controlling the working state of the suspension component, and reduces the manpower input in the placement process of the suspension component. This achieves the technical effect of reducing the cost of placing suspension components to protect the protection screen in the substation, and solves the technical problem of high cost of safety protection for substation secondary equipment operations in related technologies.

[0048] Furthermore, based on the text recognition results, a text database matching the work ticket identifier is constructed, including: obtaining a sample database matching the work ticket identifier, and at least one text name contained in the sample database; extracting text extraction rules matching the text names from a rule base, wherein the rule base is used to store the mapping relationship between text extraction rules and text names; extracting a first text matching the text name from the text recognition results based on the text extraction rules; and populating the sample database based on the first text and the text name to obtain the text database.

[0049] The aforementioned sample database can be a database storing the aforementioned text recognition results. The aforementioned text name can be a field name from the aforementioned recognition results, such as the work order number, substation name, work task, work location, or safety measures, but is not limited to these. The aforementioned first text can be characters extracted based on the aforementioned extraction rules.

[0050] In one optional embodiment, considering that the work order contains a large amount of text information, and different text information may play different roles during the operation of the protection device, if each different data from the same work order read from the text database includes all the text recognition results of the work order, it may lead to poor reading efficiency and potentially bring significant maintenance costs to the database. Therefore, the protection system can first extract the work order identifier based on the recognized text information, then use the work order identifier as the key and the text name corresponding to the work order identifier as the value to construct multiple key-value pairs. A relational database can be used to store and manage these key-value pairs to construct a sample database, thereby refining the storage of different text recognition results on the same work order. To improve the accuracy of data reading, the protection system can further obtain the rules corresponding to the different text names from the rule base, extract the characters or strings corresponding to the text names from the text recognition results based on the rules, and then use the text name as the key and the aforementioned characters or strings as the value to construct multiple key-value pairs again. These key-value pairs are then stored in the corresponding positions in the sample database to construct the text database.

[0051] For example, if the text name above could contain "work location", the corresponding rule in the rule base could be: if the content of the work location contains "*room*: *screen in front" (or "*room*: *screen behind", or "*room*: *screen before and after"), then the colon ":" along with the preceding "*room*" is extracted to obtain "*room*:". If "*screen in front" (or "*screen behind", or "*screen before and after") appears in the subsequent text, then the characters containing "*screen in front" (or "*screen behind", or "*screen before and after") are extracted using the comma "、" as the extraction boundary, and arranged in order after the previously extracted "*room*:". Here, the asterisk "*" represents any character or string. Specifically, for example, the above work location content could be "1. 500kV substation A relay protection room 2: 15P 500kV fault ranging panel in front, 3P monitoring remote control and network panel behind, 8P line ranging panel in front". According to the above rules, the extracted string is as follows: "500kV substation A relay protection room 2: 15P 500kV fault ranging panel in front, 8P line ranging panel in front".

[0052] For example, the text name mentioned above could contain "safety measures," which is text used to control the suspended component. The corresponding rule in the rule base could be: if the content of the safety measures contains "*room*:*screen in front" (or "*room*:*screen behind", or "*room*:*screen before and after"), then use "*room*:*screen in front" (or "*room*:*screen behind", or "*room*:*screen before and after") as the starting point for text extraction, and extract the entire string of characters. Specifically, for example, the content of the safety measures mentioned above could be:

[0053] "1. Hang a sign saying 'Working Here' behind the 500kV fault ranging panel (2:15P) and the monitoring remote control and network panel (3P) in the relay protection room A of the 500kV substation. Also, hang a red cloth saying 'Equipment in Operation!' in front of the panel and behind the adjacent operating panel."

[0054] 2. Hang a sign saying "Working Here" in front of the 0202:1P remote control monitoring panel and the 128P intelligent remote control panel in the computer studio of the 500kV substation A, and hang a red cloth saying "Equipment in operation!" behind the panel and in front of the adjacent operating panel.

[0055] According to the above rules, the extracted string is as follows: "Hang a sign saying 'Working here' behind the 500kV fault ranging panel 2:15P and the monitoring remote control and network panel 3P in the relay protection room 2 of the 500kV substation, and hang a red cloth saying 'Equipment is in operation!' in front of its panel and behind the adjacent operating panel."

[0056] It should be noted that the extraction results corresponding to "*room*: *in front of screen" above are only illustrative examples. In actual applications, the above content related to work location can include one or more of "*room*: *in front of screen", "*room*: *behind screen", and "*room*: *before and after screen", without any specific limitation.

[0057] It should be noted that the punctuation mark '' used above to limit certain words is only an example. Users can choose according to their actual situation, such as selecting "", without any specific limitation.

[0058] Furthermore, based on the data reading logic corresponding to the work order identifier, the device control parameters of the protective device are determined from the text database, including: obtaining the device identifier of the protective device; determining the target text name that matches the device identifier from the text names contained in the text database; reading the second text corresponding to the target text name from the text database based on the data reading logic; and processing the second text according to the preset text logic to obtain the device control parameters.

[0059] The aforementioned device identifier may be the location information of the protective device. The aforementioned target text name may be a text name that affects the operation of the protective device. The aforementioned second text may be the characters or strings corresponding to the aforementioned target text name in the aforementioned text database. The aforementioned preset text logic may be logic capable of automatically generating corresponding security measures based on the aforementioned second text; for example, it may be an artificial intelligence algorithm, a predefined rule, but is not limited to these.

[0060] In one optional embodiment, considering the large number of protective devices, to improve the accuracy of the protection system's control over these devices, the protection system needs to accurately obtain the device control parameters corresponding to the target protective device from a text database. Therefore, the protection system can first obtain the device identifier of the protective device, which can correspond to a text name in the text database. This allows the protection system to accurately determine the target text name from multiple text names stored in the text database based on the device identifier. Then, the protection system can read the corresponding second text from the text database based on the target text name. However, the second text may not be directly usable by the protection system. Therefore, it is necessary to process the second text using preset text logic to obtain the device control parameters of the control device.

[0061] For example, the deep learning algorithm has completed model training. The device identification of the aforementioned protective device could be "Red curtain hanging device in front of the dispatch monitoring remote control panel of 500kV substation A computer studio 0202:1P" and "Red curtain hanging device behind the 500kV fault ranging panel of 500kV substation B relay protection room 2:15P". The target text name matched in the text database could be "work location". Based on the above data reading logic, the second text read from the text database is the corresponding "in front of the panel" and "behind the panel" related information. Based on the model trained by the deep learning algorithm, the generated device control parameters are: "Hang a 'Working Here' sign in front of the dispatch monitoring remote control panel of 500kV substation A computer studio 0202:1P, and hang a 'Equipment in Operation!' red cloth behind the panel and in front of the adjacent operating panel", and "Hang a 'Equipment in Operation!' red cloth behind the panel of 500kV substation B relay protection room 2:15P". A sign reading "Working" is hung behind the 500kV fault ranging panel, and a red cloth reading "Equipment in operation!" is hung in front of the panel and behind adjacent operating panels.

[0062] For example, the rule engine has been configured with mapping rules for protective devices and safety measures at different locations. The device identifier of the aforementioned protective device could be "the device hanging on the red curtain in front of the 1:3P remote control monitoring screen in the C computer room of the 500kV substation" and "the device hanging on the red curtain behind the 500kV fault ranging screen in the D relay protection room 3:5P of the 500kV substation". The target text name matched in the text database could be "work location". Based on the above data reading logic, the second text read from the text database is "in front of the screen" and "behind the screen". Based on the mapping rule in the rule engine that the work location is "in front of the screen", the generated device control parameters are "hanging a 'Working Here' sign in front of the 1:3P remote control monitoring screen in the C computer room of the 500kV substation, and hanging a 'Equipment in Operation!' red cloth behind its screen and in front of the adjacent operating screen". Based on the generation rule in the rule engine that the work location is "behind the screen", the generated device control parameters are "hanging a 'Working Here!' sign in front of the 1:3P remote control monitoring screen in the C computer room of the 500kV substation". A sign reading "Working" is hung behind the 500kV fault ranging panel, and a red cloth reading "Equipment in operation!" is hung in front of the panel and behind adjacent operating panels.

[0063] Furthermore, the second text includes at least: work location text and suspension component control text, and the device control parameters include at least: component control parameters and component display parameters. The second text is processed according to a preset text logic to obtain the device control parameters, including: determining at least one target component from at least one suspension component based on the work location text; and determining the component control parameters and component display parameters of the target component based on the suspension component control text.

[0064] The aforementioned work location text can be characters or strings describing the work location. For example, the aforementioned work location text includes at least one or more of the following: front of the protective screen, back of the protective screen, and both front and back of the protective screen, but is not limited to these. The aforementioned suspension component control text can be text describing how to control the operation of the suspension component. The aforementioned component control parameters can be parameters that instruct the aforementioned suspension component to deploy or retract. The aforementioned component display parameters can be the text content displayed by the suspension component, for example, it can be "Equipment is running!" or "Equipment is under maintenance!", but is not limited to these.

[0065] In one alternative embodiment, considering that multiple suspension components can typically be configured in the protective device, with different suspension components acting at different positions on the protective screen, such as the front and back of the screen, the protective system needs to be able to determine the target component based on the aforementioned second text in order to accurately identify the target component that needs to be controlled. Since each sub-component has a definite location identifier, the protective system can first parse the working location text from the second text, and then accurately locate at least one target component based on this working location text. Furthermore, to control the operating state of the protective device, the protective system can also parse the corresponding suspension component control text from the second text, and determine the component control parameters and component display parameters of the target component based on this suspension component control text.

[0066] For example, the second text read from the text database based on the above data reading logic may include the work location: "500kV substation B relay protection room 6:2P 500kV fault location panel in front", and the hanging component control text: "Hang a 'Working Here' sign in front of the 500kV substation B fault location panel, and unfold the red cloth behind the panel and the red cloth in front of the adjacent operating panel, with the words 'Equipment in operation!' on the red cloth". According to the hanging component control text, it can be determined that the current component control parameter can be "Hang a sign in front of the 500kV substation B fault location panel, and unfold the red cloth behind the panel and the red cloth in front of the adjacent operating panel", and it can also be determined that the component display parameter can be "Working Here" displayed on the sign and "Equipment in operation!" displayed on the red cloth.

[0067] Furthermore, controlling the working state of the suspension component based on the device control parameters includes: verifying the device control parameters according to a preset method to obtain the parameter verification result; in response to the parameter verification result indicating that the device control parameters are normal and receiving a parameter execution command, sending the device control parameters to the control device of the target component; and controlling the working state of the target component according to the device control parameters based on the control device.

[0068] The aforementioned preset method can be a logic for verifying the control parameters of the aforementioned device, such as an artificial intelligence algorithm or a string matching algorithm, but it is not limited to these. The aforementioned parameter verification result includes at least: the device control parameters are normal or the device control parameters are abnormal, but it is not limited to these.

[0069] In one optional embodiment, the protection system reads the second text from the aforementioned text database and processes it using preset text logic to obtain device control parameters. Considering that errors may occur during the reading or processing, leading to discrepancies between the final device control parameters and actual protection requirements, or even failure to meet those requirements, the protection system also needs to verify the obtained device control parameters according to a preset method. When the verification result indicates that the device control parameters are normal, the control device can receive parameter commands sent by the protection system and control the operation of the protection device based on the device control parameters to correspond to the working state of the target component, thereby improving the accuracy of controlling the protection device.

[0070] For example, based on the second text mentioned above, the safety measure generation model trained by deep learning algorithms can automatically generate device control parameters such as: "Hang a 'Working Here' sign behind the 5:2P remote control monitoring screen in the F computer studio of the 500kV substation, and hang a red cloth with the words 'Equipment is in operation!' in front of its screen and behind the adjacent operating screen." However, the actual safety measure on the work order recognized by the OCR recognition device is "Hang a 'Working Here' sign behind the 5:2P remote control monitoring screen in the F computer studio of the 500kV substation, and hang a red cloth with the words 'Equipment is in operation!' in front of its screen and behind the adjacent operating screen." Using a string matching model trained by deep learning algorithms, it can be verified that the automatically generated safety measure is consistent with the actual safety measure on the work order. Therefore, the parameter verification result is that the device control parameters are normal. Finally, the red cloth hanging device receives the parameter execution instruction and unfolds the red cloth with the words "Equipment is in operation!" in front of the 5:2P remote control monitoring screen in the F computer studio of the 500kV substation and behind the adjacent operating screen.

[0071] For example, based on the second text mentioned above, the automatically generated device control parameters, generated through the corresponding rules in the rule engine, could be: "Hang a 'Working Here' sign in front of and behind the 500kV fault location panel in the G relay protection room of the 500kV substation (1:1P), and hang a red cloth with the words 'Equipment in Operation!' in front of and behind the adjacent operating panel." The actual safety measures on the work order, as recognized by the OCR recognition device, are: "Hang a 'Working Here' sign in front of and behind the 500kV fault location panel in the G relay protection room of the 500kV substation (1:1P), and hang a red cloth with the words 'Equipment in Operation!' in front of and behind the adjacent operating panel." Using a string matching algorithm, the string content of the automatically generated safety measures can be compared with the string content of the actual safety measures on the work order. The comparison results show that they are consistent. Therefore, the parameter verification result indicates that the device control parameters are normal. Finally, the red cloth hanging device receives the parameter execution command and unfolds a red cloth with the words "Equipment in Operation!" in front of and behind the adjacent operating panel of the 500kV fault location panel in the G relay protection room of the 500kV substation (1:1P).

[0072] Furthermore, the method also includes: in response to the parameter verification result being abnormal, not sending the device control parameters to the control device, and outputting a first prompt message, wherein the first prompt message is used to prompt the user that there is an abnormality in the device control parameters.

[0073] The aforementioned first prompt message may be a signal indicating abnormal device control parameters to the staff, such as text signals, image signals, but not limited to these.

[0074] In an optional embodiment, considering that the above parameter verification result may be that the device control parameters are abnormal, the protection system needs to respond to the above abnormal situation. Therefore, when the parameter verification result is that the device control parameters are abnormal, the protection system may not send the device control parameters to the control device, but instead output prompt information to the user interface to improve the correctness of the safety measures and reduce the risk of accidents caused by improper safety measures.

[0075] For example, a safety measure generation model trained using deep learning algorithms can automatically generate device control parameters such as: "Hang a 'Work Here' sign behind the 5:2P remote control monitoring screen in the F computer studio of the 500kV substation, and hang a red cloth saying 'Equipment is in operation!' in front of its screen and behind the adjacent operating screen." However, the actual safety measure on the work order recognized by the OCR recognition device is "Hang a 'Work Here' sign in front of the 5:2P remote control monitoring screen in the F computer studio of the 500kV substation, and hang a red cloth saying 'Equipment is in operation!' in front of its screen and behind the adjacent operating screen." Using a string matching model trained using deep learning algorithms, it can be verified that the automatically generated safety measure is inconsistent with the actual safety measure on the work order. Therefore, the parameter verification result is that the device control parameters are abnormal. In this case, the device control parameters can be directly not sent to the control device, and the message "Work location and work safety measures do not correspond" can be displayed on the tablet interface to prompt the staff that the device control parameters are abnormal.

[0076] For example, based on the second text mentioned above, the automatically generated device control parameters, generated by the corresponding rules in the rule engine, could be: "Hang a 'Working Here' sign in front and behind the 1:1P 500kV fault ranging screen in the G relay protection room of the 500kV substation, and hang a red cloth saying 'Equipment is in operation!' in front of the adjacent operating screen." However, the actual safety measures on the work order recognized by the OCR recognition device are: "Hang a 'Working Here' sign in front and behind the 1:1P 500kV fault ranging screen in the G relay protection room of the 500kV substation, and hang a red cloth saying 'Equipment is in operation!' in front and behind the adjacent operating screen." Using a string matching algorithm, the string content of the automatically generated safety measures can be compared with the string content of the actual safety measures on the work order. The comparison results show that the two are inconsistent. Therefore, the parameter verification result is that the device control parameters are abnormal. In this case, the device control parameters can also not be sent to the control device, and the window displaying the device control parameters on the mobile phone interface can be changed to red to prompt the staff that the device control parameters are abnormal.

[0077] Furthermore, the device control parameters are verified according to a preset method to obtain parameter verification results, including: obtaining control parameter extraction rules that match the work order identifier; extracting initial control parameters from the text recognition results based on the control parameter extraction rules; determining that the parameter verification result is normal for the device control parameters in response to the initial control parameters being the same as the device control parameters; and determining that the parameter verification result is abnormal for the device control parameters in response to the initial control parameters being different from the device control parameters.

[0078] The aforementioned control parameter extraction rules can be rules used to extract initial control parameters from text recognition results. These initial control parameters can refer to the original safety measures specified on the work order.

[0079] In one optional embodiment, considering that a single operation may involve multiple device control parameters corresponding to a work order, the protection system needs to verify these multiple device control parameters. There may be scenarios where the parameter verification results do not match the work order identifier, leading to low accuracy of the verification results. Therefore, the protection system can first obtain control parameter extraction rules that match the work order identifier, thereby accurately extracting the device control parameters corresponding to different work orders. Then, the protection system can extract initial control parameters from the text recognition results based on the aforementioned control parameter extraction rules, and compare these initial control parameters with the actual device control parameters on the work order. If the comparison results show that they are the same, the parameter verification result is determined to be that the device control parameters are normal; if the comparison results show that they are different, the parameter verification result is determined to be that the device control parameters are abnormal.

[0080] For example, based on the second text mentioned above, the safety measure generation model trained by deep learning algorithms can automatically generate device control parameters such as: "Hang a 'Working Here' sign behind the 2P ground control monitoring remote control panel in the 500kV substation F computer studio 5, and hang a 'Equipment in Operation!' red cloth in front of the panel and behind the adjacent operating panel." The extraction rule for the above control parameters can be: after detecting the string "A barrier should be installed, a sign should be hung (location):", divide the text after the colon ":" in the string into multiple segments using semicolons ";". Use the protection room included in the work location in the second text as the search condition, such as "in the 500kV substation F computer studio 5" in the second text. Retrieve the segment containing the string "this protection room". Since the same protection room can have work in front of, behind, or both sides of the panel, extract the segment containing the string "behind" (in front of or behind) based on the protection panel of the work location in the second text, such as behind the 2P ground control monitoring remote control panel. After the OCR recognition device identifies the "should be installed with barriers and signs (location):" on the work order, it extracts the initial control parameters according to the above rules. The parameters are "hang a 'Working Here' sign behind the 5:2P remote control monitoring panel in the F computer studio of the 500kV substation, and hang a 'Equipment in Operation!' red cloth in front of its panel and behind the adjacent operating panel". Using a string matching model trained by a deep learning algorithm, it can verify that the automatically generated safety measures are consistent with the actual safety measures on the work order. Therefore, the parameter verification result is that the device control parameters are normal.

[0081] Furthermore, the method also includes: in response to the start of operation of the protective device, monitoring the operating parameters of the protective device to obtain device monitoring parameters; matching the device monitoring parameters with the device control parameters to obtain parameter matching results; in response to the parameter matching result indicating that the device monitoring parameters are normal and receiving an execution completion command, controlling the protective device to stop operation; in response to the parameter matching result indicating that the device monitoring parameters are abnormal, outputting a second prompt message, wherein the second prompt message is used to prompt the user that the protective device is not operating normally.

[0082] The aforementioned device monitoring parameters can be data characterizing the current operating status of the protective device. The aforementioned parameter matching results can be data characterizing whether the device monitoring parameters and the device control parameters are consistent. The aforementioned second prompt information can be a signal indicating to the staff that the protective device is not in operation; for example, it can be a text signal, an image signal, but is not limited to these.

[0083] In one optional embodiment, the protection system sends an operation command for the protection device to the control system. Considering the possibility of abnormal situations during operation, such as damage to the suspension components of the protection device causing the operation command to not be responded to correctly, thus creating a safety hazard, the protection system monitors the operating parameters of the protection device when it starts operating to obtain device monitoring parameters, achieving real-time monitoring of the protection device's operating status. Then, to verify whether the current operating status of the protection device meets the actual protection requirements, the protection system matches the device monitoring parameters with the device control parameters to obtain a parameter matching result. If the parameter matching result indicates that the device monitoring parameters are normal, the control system controls the protection device to terminate operation after receiving the work completion command from the protection system. If the parameter matching result indicates that the device monitoring parameters are abnormal, the protection system outputs a prompt message to the user, enabling the user to promptly detect abnormalities in the protection device and reduce the risk of accidents.

[0084] For example, the device control parameters generated after verification by the protection system could be: "Hang 'Working Here' signs in front of and behind the 500kV fault ranging panel in the 13:2P relay protection room of the 500kV substation, and hang 'Equipment in Operation!' red cloths in front of and behind adjacent operating panels." The red cloth hanging device starts operating based on the above device control parameters and unfolds the red cloth. Monitoring the operating parameters of the above red cloth hanging device yields the device monitoring parameters: "'Working Here' signs have been hung in front of and behind the 500kV fault ranging panel in the 13:2P relay protection room of the 500kV substation, and 'Equipment in Operation!' red cloths have been unfolded in front of and behind adjacent operating panels." At this point, the parameter matching result indicates that the device monitoring parameters are normal, and the execution completion command has been received, and the above red cloth hanging device ends operation.

[0085] For example, the device control parameters generated after verification by the protection system could be: "Hang a 'Working Here' sign behind the 500kV monitoring remote control and network screen in the T computer room of the 500kV substation (0211:5P), and hang a 'Equipment in Operation!' red cloth in front of its screen and behind adjacent operating screens." The red cloth hanging device starts operating based on the above device control parameters, but does not unfold the red cloth. Monitoring the operating parameters of the above red cloth hanging device yields the device monitoring parameters: "The 'Working Here' sign has been hung behind the 500kV monitoring remote control and network screen in the T computer room of the 500kV substation (0211:5P), but the 'Equipment in Operation!' red cloth has not been unfolded in front of its screen and behind adjacent operating screens." In this case, the parameter matching result indicates that the device monitoring parameters are abnormal, and the tablet interface outputs the prompt message: "The red cloth has not been unfolded in front of the 500kV monitoring remote control and network screen in the T computer room of the 500kV substation (0211:5P) and behind adjacent operating screens."

[0086] To help users better understand the prompts, the protection system can also provide corresponding information. Figure 2 The multiple 3D images shown illustrate the status of different suspension components. For example, if a red cloth is not required to be suspended normally, the overall white color remains unchanged; if a red cloth should be suspended and is successfully suspended, a red "Device in operation" message can be displayed in front of or behind the screen; if a cloth should be suspended but is not successfully suspended, a blue background can flash in front of or behind the corresponding screen.

[0087] For example, the device control parameters generated by the protection system could be: "Hang a 'Working Here' sign in front of the 500kV monitoring remote control and network screen in computer room P 0303:1P of the 500kV substation, and hang a 'Equipment in Operation!' red cloth behind the screen and in front of the adjacent operating screen." The red cloth hanging device starts operating based on the above device control parameters, but does not unfold the red cloth. Monitoring the operating parameters of the above red cloth hanging device yields the following device monitoring parameters: "A 'Working Here' sign has been hung in front of the 500kV monitoring remote control and network screen in computer room T 0303:1P of the 500kV substation, but the 'Equipment in Operation!' red cloth has not been unfolded behind the screen and in front of the adjacent operating screen." In this case, the parameter matching result indicates that the device monitoring parameters are abnormal, and the window displaying the device monitoring parameters on the mobile phone interface turns red to alert the staff that the device monitoring parameters are abnormal.

[0088] Figure 3 This is a detailed flowchart of a substation secondary equipment operation safety protection method according to an embodiment of the present invention, as shown below. Figure 3As shown, the OCR system first identifies and extracts text information from the work order, including the substation, order number, work task, safety measures, and work location, and obtains the text recognition results. It's important to note that the form of the work order is not limited; it can be electronic or paper, but is not limited to these. Based on the text recognition results, the text data in the work order is categorized to obtain a protection screen classification database. The protection system extracts the work location-related portion of the work order from the classification database, automatically generates corresponding safety measures based on this information, and then compares them with the safety measures extracted from the protection screen classification database by the OCR system. If the comparison results show inconsistencies between the two safety measures, an alarm is issued to the user; if the comparison results show consistency, a protection screen plan is displayed on the tablet interface, and the user can confirm on the tablet interface. At this point, the work instruction is sent to the control system corresponding to the protection device, which automatically unfolds the red curtain. When the work is completed, the user selects the corresponding substation on the tablet interface, finds the work ticket number, and clicks "Complete." At this point, the completion command is sent to the control system corresponding to the protective device, which controls the automatic retraction of the red curtain. It should be noted that if the red curtain is not opened or retracted as required, the control system corresponding to the protective device can also output corresponding alarm information to the tablet interface. This alarm information can indicate the specific location of the fault, facilitating troubleshooting by staff.

[0089] For ease of understanding, Figure 4 This is a schematic diagram of a red curtain device for a substation secondary equipment operation safety protection method according to an embodiment of the present invention, as shown below. Figure 4As shown, the aforementioned protective device includes: a protective screen name 402, a movable door 404 for the protective screen, a guide rail 406, a red curtain 408, and a fixed end 410. The protective screen name 402 is used to distinguish different protective screens and can display the current protective screen's identification mark, i.e., (XX P) XXX screen. For example, the content on the protective screen name 402 could be: (2P) Ground Control Monitoring Remote Screen, but it is not limited to this. The movable door 404 of the protective screen is used for physical isolation of live equipment. The guide rail 406 provides a guiding path for the automatic retraction and deployment of the red curtain 408, ensuring that the red curtain 408 can move smoothly and accurately during deployment and retraction, avoiding jamming or deviation, thereby improving the accuracy and effectiveness of the safety measures. The red curtain 408 is used to isolate live equipment and maintenance areas, preventing workers or unauthorized personnel from accidentally touching live parts, ensuring personal and equipment safety. It should be noted that the markings on the red curtain 408 can be changed according to actual needs; for example, it could read "Equipment in operation" or "Equipment under maintenance," but it is not limited to these. The fixed end 410 securely installs the red curtain 408 in a predetermined position on the protective screen, ensuring that the red curtain 408 will not move or fall off due to external forces during use, guaranteeing the effectiveness of safety isolation. Furthermore, the fixed end 410 also contains a motor, gears, a transmission system, and a control system. It transmits commands from the tablet to the control system, which receives command signals from the tablet and, through the coordination of the motor, gears, transmission system, and control system, initiates the automatic deployment or retraction of the red curtain 408, achieving automated control of the red curtain 408.

[0090] According to another aspect of the present invention, a safety protection device for substation secondary equipment operation is also provided. It should be noted that the device can be used to perform the above-mentioned safety protection method for substation secondary equipment operation. The specific implementation method and application scenario are the same as those in the above embodiments, and will not be repeated here.

[0091] Figure 5 This is a schematic diagram of a substation secondary equipment operation safety protection device according to an embodiment of the present invention, such as... Figure 5 As shown, the above-mentioned device includes: a work order recognition module 502, used to recognize the text information contained in the work order and obtain the text recognition result; a database construction module 504, used to construct a text database matching the work order identifier of the work order based on the text recognition result; a parameter determination module 506, used to determine the device control parameters of the protection device from the text database based on the data reading logic corresponding to the work order identifier, wherein the protection device includes: at least one suspension component, the position of the suspension component corresponds to the position of the protection panel in the substation, and the suspension component is used to isolate the protection panel when it is in the deployed state; and a device control module 508, used to control the operation of the protection device based on the device control parameters.

[0092] Furthermore, the database construction module 504 is also used to: obtain a sample database that matches the work ticket identifier, and at least one text name contained in the sample database; extract text extraction rules that match the text names from the rule base, wherein the rule base is used to store the mapping relationship between text extraction rules and text names; extract a first text that matches the text name from the text recognition result based on the text extraction rules; and populate the sample database based on the first text and the text name to obtain a text database.

[0093] Furthermore, the parameter determination module 506 is also used to: obtain the device identifier of the protective device; determine the target text name that matches the device identifier from the text names contained in the text database; read the second text corresponding to the target text name from the text database based on the data reading logic; and process the second text according to the preset text logic to obtain the device control parameters.

[0094] Furthermore, the second text includes at least: work location text and suspension component control text, and the device control parameters include at least: component control parameters and component display parameters. The parameter determination module 506 is also used to: determine at least one target component from at least one suspension component based on the work location text; and determine the component control parameters and component display parameters of the target component based on the suspension component control text.

[0095] Furthermore, the device control module 508 is also used to: verify the device control parameters according to a preset method and obtain the parameter verification result; in response to the parameter verification result indicating that the device control parameters are normal and receiving a parameter execution instruction, send the device control parameters to the control device of the target component; and control the operation of the protection device according to the device control parameters based on the control device.

[0096] Furthermore, the above-mentioned device also includes: a first output module, used to respond to the parameter verification result being that the device control parameters are abnormal, not to send the device control parameters to the control device, and to output a first prompt message, wherein the first prompt message is used to prompt the user that the device control parameters are abnormal.

[0097] Furthermore, the device control module 508 is also used to: acquire control parameter extraction rules that match the work order identifier; extract initial control parameters from the text recognition results based on the control parameter extraction rules; determine that the parameter verification result is normal if the initial control parameters are the same as the device control parameters; and determine that the parameter verification result is abnormal if the initial control parameters are different from the device control parameters.

[0098] Furthermore, the aforementioned device also includes: a parameter detection module, used to monitor the operating parameters of the protective device in response to the start of operation of the protective device, and obtain the device monitoring parameters; a parameter matching module, used to match the device monitoring parameters with the device control parameters, and obtain the parameter matching result; a first control module, used to control the protective device to stop operation in response to the parameter matching result indicating that the device monitoring parameters are normal and to receive an execution completion instruction; and a second output module, used to output a second prompt message in response to the parameter matching result indicating that the device monitoring parameters are abnormal, wherein the second prompt message is used to prompt the user that the protective device is not operating normally.
