Description

Technical Field

[0001] This invention belongs to the field of power system technology error prevention, specifically relating to an intelligent error prevention system and method for electronic work tickets for power lines. Background Technology

[0002] The power line work permit system is a fundamental organizational measure to ensure the safety of power line maintenance work. The overall process involves the work permit issuer issuing the work permit, and the work permit issuer and the work supervisor signing for the issued work permit. Once the power grid safety measures are met, the work permit issuer authorizes the work permit to the work supervisor. Only after completing the authorization procedures can the work supervisor organize on-site work. After the on-site work is completed, the work supervisor terminates the work permit with the work permit issuer.

[0003] Existing technology has enabled the electronic circulation of the entire process of power line work permits, and traditional paper work permits are gradually being replaced by electronic work permits. However, the two still maintain a basic consistency in business processes, dividing the work permit process into four stages: pending signature, pending approval, pending termination, and terminated. These four stages form a closed loop for the power line work permit approval process.

[0004] Current technical solutions merely convert power line work permits from paper to electronic, i.e., from offline to online. While this saves paper, it doesn't directly improve safety. Therefore, electronic power line work permits still face the following challenges:

[0005] 1. Insufficient safety and error prevention capabilities. The security of electronic work permits for power lines still relies on the professional competence and meticulousness of the work permit issuer, work supervisor, and work permit approver, without employing multiple layers of technical safeguards for the work permits. Especially when work on the same line requires applying voltage, multiple work permits may be mutually exclusive. These work permits are effectively interlocked, but due to the current lack of technical safeguards, they can only rely on the work permit approver for verification.

[0006] 2. Weak information integration capabilities. Currently, electronic work permits for power lines involving the same route are processed by the work permit issuer through integration and association. Insufficient technical means are used for efficient bundling, resulting in a large workload and the risk of missing associations, thus posing potential risks to the issuance of power line work permits. Summary of the Invention

[0007] The purpose of this invention is to solve the above-mentioned problems and provide an intelligent anti-error system and method for electronic work permits for power lines. This system enables multiple intelligent security checks on work permits and further integrates information such as the work line, work location, work content, and safety measures on the electronic work permits for power lines, intelligently establishing associations between multiple work permits involving the same power line. Based on this, strong interlocking relationships are established for specific work permits that may pose personal risks to power line workers, thereby improving the technical anti-error level of electronic work permits for power lines.

[0008] To achieve the above objectives, the technical solution of the present invention is: an intelligent anti-error system for electronic work permits for power lines, comprising a work permit management module and a work permit anti-error module; wherein,

[0009] The work order management module includes a pending signature unit, a pending authorization unit, a bundling unit, a pending termination unit, and an archiving unit. The pending signature unit is used for pre-signing electronic work orders for power lines and pushing them to the self-inspection unit. The pending authorization unit is used to enable authorization for electronic work orders for power lines that have passed the self-inspection unit and been signed. The bundling unit is used to bundle multiple electronic work orders for power lines with overlapping safety measures to form a work order bundle. The pending termination unit is used to enable termination for authorized electronic work orders for power lines. The archiving unit is used to archive terminated electronic work orders for power lines.

[0010] The work order anti-error module includes a self-checking unit, a real-time anti-error unit, a data service unit, a real-time interaction unit, and a related anti-error unit. The self-checking unit performs a three-level anti-error verification check on the information on the electronic work order for power lines. The real-time anti-error unit performs real-time anti-error security verification on the authorized electronic work orders for power lines. The data service unit receives and parses data from the real-time anti-error unit and the real-time interaction unit, and compares the data. The real-time interaction unit reads data from the EMS system in real time and transmits the read data to the data service unit. The related anti-error unit receives the bundled information of the electronic work order for power lines pushed by the bundling unit and retrieves key fields to establish a related anti-error interlock.

[0011] In one embodiment of the present invention, the specific implementation method of the self-testing unit performing a three-level anti-misoperation verification check on the ticket information of the electronic work ticket for power lines is as follows:

[0012] For the electronic work order for power lines that is in the pending acceptance stage, the fields of work line and work location are compared pairwise, and the two parts of the field content "**kVxx line" are extracted. If the two parts of the field content are completely consistent, the first level of error prevention verification is judged to be passed; among them, the "**" character is Arabic numeral, and the "xx" character is not restricted;

[0013] For the electronic work order for power lines that is in the pending acceptance stage, the field content of the work line and work content is compared pairwise, and the two parts of the field content "**kVxx line" are extracted. If the two parts of the field content are completely consistent, the second level of error prevention verification is judged to be passed.

[0014] For the electronic work tickets of power lines that are in the pending acceptance stage, the field contents of the work line and safety measures "name of the line bay that should be converted to maintenance status" are compared pairwise, and the two parts of the field contents "**kVxx line" are extracted. If the two parts of the field contents are completely consistent, the third level of error prevention verification is judged to be passed.

[0015] After passing the three-level anti-misoperation verification check, the electronic work order for power lines will be enabled for signing. Once the electronic work order for power lines is signed, the process will be transferred to the unit awaiting permission. If any level of anti-misoperation verification fails, the system will lock the signing and issue an alarm.

[0016] In one embodiment of the present invention, the specific implementation method of the bundling unit bundling multiple electronic work orders for power lines with overlapping safety measures to form a work order bundle is as follows:

[0017] The bundling unit retrieves the field content "**kVxx line" of the safety measures "Line bay name that should be converted to maintenance status" from all electronic work tickets for power lines in the pending acceptance unit, pending approval unit, and pending termination unit, and compares them. It then generates a bundle for each electronic work ticket with completely non-overlapping safety measures. If multiple electronic work tickets have overlapping "**kVxx line" fields in the safety measures "Line bay name that should be converted to maintenance status", they are bundled together, and the bundle is associated with multiple electronic work tickets for power lines. When the electronic work ticket process flows to the archiving unit, the corresponding electronic work ticket for power lines is removed from the bundle.

[0018] In one embodiment of the present invention, the unit to be authorized opens the authorization function for the electronic work order of power line that has passed the self-inspection unit and has been signed. That is, when the authorization is clicked on the electronic work order of power line that is pending authorization, the work order management module will push the safety measures information of the electronic work order of power line to the real-time anti-error unit of the work order anti-error module. The real-time anti-error unit parses the information in the safety measures, including the substation name, voltage level, line name and line status, and requests the above information from the data service unit.

[0019] In one embodiment of the present invention, the data service unit reads the substation name, voltage level, and line name, and then pushes them to the real-time interaction unit. The real-time interaction unit interacts with the EMS system in real time, reads the status information of the corresponding equipment through the substation name, voltage level, and line name, and returns the status information to the real-time interaction unit. The real-time interaction unit further transmits the status information to the data service unit, which compares the line status received from the real-time error prevention unit and the data service unit respectively. If the line status information is consistent, the real-time error prevention verification passes, and the electronic work ticket for the power line is pushed to the associated error prevention unit. If the status information is inconsistent, the real-time error prevention verification fails, the system will issue an alarm, and the licensor of the electronic work ticket for the power line will forcibly unlock it or return the electronic work ticket for the power line to the pending licensor unit.

[0020] In one embodiment of the present invention, the associated anti-error unit obtains the field content of the work content in all electronic work orders for power lines within all bundles. When the field content of the work content of a certain electronic work order for power lines contains a field including "parameter test" or "pressure increase", an anti-error interlocking relationship is established for that electronic work order for power lines. When any electronic work order for power lines in any bundle is in the pending termination unit, electronic work orders for power lines whose work content includes fields including "parameter test" or "pressure increase" will fail the safety verification by the associated anti-error unit, and an alarm prompt will be given to the work permit holder.

[0021] In one embodiment of the present invention, when an electronic work order for power lines containing fields such as "parameter testing" or "pressure application" is in the pending termination stage, the electronic work order for power lines in the pending licensing stage within the corresponding bundle will fail to pass the security verification of the associated anti-misoperation unit and will give an alarm prompt to the work licenser.

[0022] In one embodiment of the present invention, the system interlocking library supports the manual addition of key fields to enable the electronic work ticket authorization interlocking function for power lines, and the electronic work ticket authorization interlocking function for power lines has the function of manual release after the work permit holder's review.

[0023] In one embodiment of the present invention, the method for obtaining the field content in the electronic work order for power lines adopts OCR text recognition technology.

[0024] This invention also provides an intelligent anti-error method for electronic work tickets for power lines, comprising:

[0025] S1. Electronic work orders for power lines undergo a three-level error prevention check before being signed off. Electronic work orders for power lines that pass the three-level error prevention check will have the signing function enabled; specifically...

[0026] For the electronic work order for power lines that is in the pending acceptance stage, the fields of work line and work location are compared pairwise, and the two parts of the field content "**kVxx line" are extracted. If the two parts of the field content are completely consistent, the first level of error prevention verification is judged to be passed; among them, the "**" character is Arabic numeral, and the "xx" character is not restricted;

[0027] For the electronic work order for power lines that is in the pending acceptance stage, the field content of the work line and work content is compared pairwise, and the two parts of the field content "**kVxx line" are extracted. If the two parts of the field content are completely consistent, the second level of error prevention verification is judged to be passed.

[0028] For the electronic work tickets of power lines that are in the pending acceptance stage, the field contents of the work line and safety measures "name of the line bay that should be converted to maintenance status" are compared pairwise, and the two parts of the field contents "**kVxx line" are extracted. If the two parts of the field contents are completely consistent, the third level of error prevention verification is judged to be passed.

[0029] After passing the three-level anti-misoperation verification check, the electronic work ticket for power lines will be enabled for signing. After the electronic work ticket for power lines is signed, step S2 will be executed. If any level of anti-misoperation verification fails, the system will lock the signing and issue an alarm.

[0030] S2. Obtain the field content "**kV xx line" of the safety measures section "Line bay name that should be converted to maintenance status" in all electronic work tickets for power lines and compare it to establish the interrelationship of electronic work tickets for power lines; specifically,

[0031] Retrieve the field content "**kVxx line" of the "Line bay name that should be converted to maintenance status" for all electronic work orders for power lines, and compare them; generate a bundle for each electronic work order for power lines with completely non-overlapping safety measures; if the field content "**kVxx line" of the "Line bay name that should be converted to maintenance status" for multiple electronic work orders for power lines overlaps, then bundle them together, and the bundle is associated with multiple electronic work orders for power lines; when the electronic work order process for power lines reaches the final stage, remove the corresponding electronic work order for power lines from the bundle;

[0032] S3. Obtain the field content of the work content in all electronic work orders for power lines within all bundles. When the field content of the work content of a certain electronic work order for power lines contains "parameter test" or "pressure increase", establish an anti-misoperation interlocking relationship for that electronic work order for power lines: When any electronic work order for power lines in any bundle is in the pending completion stage, electronic work orders for power lines with work content containing fields including "parameter test" or "pressure increase" will fail the safety verification of the associated anti-misoperation unit and will give an alarm prompt to the work permit holder; and when electronic work orders for power lines with work content containing fields including "parameter test" or "pressure increase" are in the pending completion stage, electronic work orders for power lines in the corresponding bundle that are in the pending permitting stage will fail the safety verification of the associated anti-misoperation unit and will give an alarm prompt to the work permit holder.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. Improve the safety and error prevention level of electronic work permits for power lines. By applying technical means to establish multi-level error prevention interlocking safety verification for single electronic work permits for power lines and multiple electronic work permits with overlapping safety measures, an additional layer of technical security measures is added to a large number of work permits that are only manually reviewed.

[0035] 2. Improve the information integration capability of electronic work permits for power lines. By identifying electronic work permits for power lines with overlapping safety measures and creating bundled packages, information integration of work permits is efficiently achieved, facilitating access for work permit issuers and improving their work efficiency. Attached Figure Description

[0036] Figure 1 This is a system block diagram of the present invention.

[0037] Figure 2 This is an example of the interface for displaying the bundled package.

[0038] Figure 3 This is a work order that is currently in the pending receipt unit.

[0039] Figure 4 To and Figure 3 Work tickets with the same work route and located in the unit to be terminated. Detailed Implementation

[0040] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings.

[0041] Reference Figure 1 This example provides an intelligent anti-error system for electronic work tickets for power lines, which mainly includes: a work ticket management module and a work ticket anti-error module.

[0042] The work order management module includes a pending signature unit, a pending authorization unit, a bundling unit, a pending termination unit, and an archiving unit. The pending signature unit is used for pre-signing electronic work orders for power lines and pushing them to the self-inspection unit. The pending authorization unit is used to grant authorization to electronic work orders for power lines that have passed the self-inspection unit and been signed. The bundling unit is used to bundle multiple electronic work orders for power lines with overlapping safety measures to form a work order bundle. The termination unit is used to grant termination functionality to authorized electronic work orders for power lines. The archiving unit is used to archive terminated electronic work orders for power lines.

[0043] The work order anti-error module includes a self-checking unit, a real-time anti-error unit, a data service unit, a real-time interaction unit, and a correlation anti-error unit. The self-checking unit performs a three-level anti-error verification check on the information on the electronic work order for power lines. The real-time anti-error unit performs real-time anti-error security verification on the approved electronic work orders for power lines. The data service unit receives and parses data from the real-time anti-error unit and the real-time interaction unit, and performs comparisons. The real-time interaction unit reads data from the EMS system in real time and transmits the read data to the data service unit. The correlation anti-error unit receives work order binding information pushed by the binding unit and retrieves key fields to establish correlation anti-error interlocks.

[0044] The self-inspection unit for electronic work orders for power lines consists of a three-level error prevention check: First, the fields for the work line and work location in the electronic work order awaiting signature are compared pairwise. The two fields "**kVxx line" are extracted ("**" represents Arabic numerals, and "xx" is not restricted). If the two fields are completely identical, the first level of error prevention check is considered passed.

[0045] Furthermore, the field content of the work order's work route and work content is compared pairwise. The two parts of the content field "**kVxx line" are extracted. If the two parts of the field content are completely consistent, the second level of error prevention verification is considered to have passed.

[0046] Furthermore, the field content of "name of line bay to be switched to maintenance status" in the work order and safety measures is compared pairwise. The two parts of the content field "**kVxx line" are extracted. If the two parts of the field content are completely consistent, the third-level error prevention check is considered to have passed.

[0047] Once the electronic work order for the aforementioned power lines passes the three-level self-inspection verification, the signature function will be enabled. After the work order is signed, the work order process will proceed to the pending authorization unit. If any level of error prevention verification fails, the system will lock the signature and issue an alarm.

[0048] Furthermore, the bundling unit retrieves and compares the "**kVxx line" field content of the "Line bay name that should be converted to maintenance status" field from all work orders pending signature, approval, and termination. Each work order with completely non-overlapping safety measures is generated into a bundle. If the "**kVxx line" field content of the "Line bay name that should be converted to maintenance status" field overlaps in multiple work orders, they are bundled together, and the bundle is associated with multiple work orders. The interrelationships between multiple work orders are identified through the bundle. An example of a bundle display interface is shown below. Figure 2 As shown. When the work order process reaches the archiving unit, the work order is removed from the bundle.

[0049] When a work order in the pending approval stage is approved, the work order management module will push the safety measures information of the work order to the real-time error prevention unit in the work order error prevention module. The real-time error prevention unit will parse the information in the safety measures, such as the substation name, voltage level, line name, and line status, and request the above information from the data service unit.

[0050] After reading the substation name, voltage level, and line name, the data service unit pushes the information to the real-time interaction unit. The real-time interaction unit then interacts with the EMS system in real time, reading the status of the equipment using the substation name, voltage level, and line name, and returning the status information to the real-time interaction unit. The real-time interaction unit further transmits the status information to the data service unit, which compares the line status received from the real-time error prevention unit and the data service unit. If the line status information matches, the real-time error prevention verification passes, and the work order is pushed to the associated error prevention unit. If the status information does not match, the real-time error prevention verification fails, the system issues an alarm, and the work order issuer must forcibly unlock the work order or return it to the pending issuer.

[0051] Furthermore, the associated error prevention unit obtains the field content of the work content in all work orders within all bundles. When the field content of a work order contains fields such as "parameter test" or "pressure application", an error prevention interlock relationship is established for that work order: when any work order in any bundle is in a pending termination unit, the work order containing the "parameter test" or "pressure application" field will fail the security verification by the associated error prevention unit, and an alarm will be issued to the work permit holder.

[0052] Furthermore, when a work order containing the fields "parameter testing" or "pressure application" is in the pending completion stage, work orders in the pending licensing stage within the bundle will fail the associated error prevention security check and will trigger an alarm for the work licensee.

[0053] The system's lockout library supports manually adding key fields to enable work ticket permission lockout functionality.

[0054] Furthermore, the electronic work permit interlocking function for power lines has the capability to be manually deactivated after review by the work permit issuer.

[0055] The method for obtaining the field content of electronic work orders for power lines adopts OCR text recognition technology. The technical process includes stages such as image input, preprocessing, layout analysis, character segmentation, character feature extraction, character recognition, layout restoration, post-processing, and proofreading.

[0056] This invention also provides an intelligent anti-error method for electronic work tickets for power lines, comprising:

[0057] S1. Electronic work orders for power lines undergo a three-level error prevention check before being signed off. Electronic work orders for power lines that pass the three-level error prevention check will have the signing function enabled; specifically...

[0058] For the electronic work order for power lines that is in the pending acceptance stage, the fields of work line and work location are compared pairwise, and the two parts of the field content "**kVxx line" are extracted. If the two parts of the field content are completely consistent, the first level of error prevention verification is judged to be passed; among them, the "**" character is Arabic numeral, and the "xx" character is not restricted;

[0059] For the electronic work order for power lines that is in the pending acceptance stage, the field content of the work line and work content is compared pairwise, and the two parts of the field content "**kVxx line" are extracted. If the two parts of the field content are completely consistent, the second level of error prevention verification is judged to be passed.

[0060] For the electronic work tickets of power lines that are in the pending acceptance stage, the field contents of the work line and safety measures "name of the line bay that should be converted to maintenance status" are compared pairwise, and the two parts of the field contents "**kVxx line" are extracted. If the two parts of the field contents are completely consistent, the third level of error prevention verification is judged to be passed.

[0061] After passing the three-level anti-misoperation verification check, the electronic work ticket for power lines will be enabled for signing. After the electronic work ticket for power lines is signed, step S2 will be executed. If any level of anti-misoperation verification fails, the system will lock the signing and issue an alarm.

[0062] S2. Obtain the field content "**kV xx line" of the safety measures section "Line bay name that should be converted to maintenance status" in all electronic work tickets for power lines and compare it to establish the interrelationship of electronic work tickets for power lines; specifically,

[0063] Retrieve the field content "**kVxx line" of the "Line bay name that should be converted to maintenance status" for all electronic work orders for power lines, and compare them; generate a bundle for each electronic work order for power lines with completely non-overlapping safety measures; if the field content "**kVxx line" of the "Line bay name that should be converted to maintenance status" for multiple electronic work orders for power lines overlaps, then bundle them together, and the bundle is associated with multiple electronic work orders for power lines; when the electronic work order process for power lines reaches the final stage, remove the corresponding electronic work order for power lines from the bundle;

[0064] S3. Obtain the field content of the work content in all electronic work orders for power lines within all bundles. When the field content of the work content of a certain electronic work order for power lines contains "parameter test" or "pressure increase", establish an anti-misoperation interlocking relationship for that electronic work order for power lines: When any electronic work order for power lines in any bundle is in the pending completion stage, electronic work orders for power lines with work content containing fields including "parameter test" or "pressure increase" will fail the safety verification of the associated anti-misoperation unit and will give an alarm prompt to the work permit holder; and when electronic work orders for power lines with work content containing fields including "parameter test" or "pressure increase" are in the pending completion stage, electronic work orders for power lines in the corresponding bundle that are in the pending permitting stage will fail the safety verification of the associated anti-misoperation unit and will give an alarm prompt to the work permit holder.

[0065] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0066] Figure 3 , Figure 4 This is the first page of two typical electronic work orders for power lines with identical work routes. Figure 3 The work order shown is in the pending receipt unit. Figure 4 The work order shown is in a pending completion unit. The work lines for both work orders are under maintenance, consistent with the safety measures stated on the orders.

[0067] For items pending signature Figure 3 The electronic work order for the power line shown retrieves the field content "110kVAB line" for both the work line and the work location. If the two fields are consistent, the first-level error prevention check of the self-inspection unit passes.

[0068] Further, the work content field "110kVAB line" on the work order is retrieved and compared with the work line field "110kVAB line". If the two fields are found to be identical, the second-level error prevention check of the self-inspection unit passes.

[0069] Further, the field content "110kVAB line" of the safety measure "name of line bay to be converted to maintenance status" in the above work order is obtained and compared with the field content "110kVAB line" of the work line. If the two fields are found to be consistent, the third-level error prevention verification of the self-inspection unit is passed, and the signing function is enabled. After signing is completed, the process is pushed to the unit awaiting permission.

[0070] Furthermore, to obtain Figure 3 , Figure 4 The safety measures field "Name of line bay to be converted to maintenance status" in the work order shown is "110kVAB line" and "110kVAB line". It is determined that the two fields overlap. A new bundle is generated for the two electronic work orders for power lines to establish a relationship between them.

[0071] Furthermore, retrieve the field content of the work content from all work tickets within the aforementioned bundle. Identify... Figure 3 The electronic work order shown contains a "parameter test" field, and an anti-misoperation interlocking relationship is established.

[0072] When on Figure 3 When the work order shown is issued, a real-time error prevention unit safety check is performed first. Since the "110kVAB line" has been transferred for maintenance, the real-time error prevention unit safety check is passed.

[0073] Furthermore, a safety check of the associated anti-misoperation units is performed. This is because the bundled package contains... Figure 4 The electronic work order shown is in the pending completion stage. Figure 3 The work order shown will disable the permission function and issue an alarm.

[0074] The above are preferred embodiments of the present invention. Any changes made to the technical solution of the present invention that do not exceed the scope of the technical solution of the present invention shall fall within the protection scope of the present invention.

The real-time interaction unit then interacts with the EMS system in real time, reading the status information of the corresponding equipment using the substation name, voltage level, and line name, and returns the status information to the real-time interaction unit. The real-time interaction unit further transmits the status information to the data service unit, which compares the line status information received from the real-time error prevention unit and the data service unit. If the line status information matches, the real-time error prevention verification passes, and the electronic work order for the power line is pushed to the associated error prevention unit. If the line status information is inconsistent, the real-time error prevention verification will fail, and the system will issue an alarm. The person who issued the electronic work ticket for the power line will then force the unlocking or return the electronic work ticket for the power line to the pending authorization unit.

5. The intelligent anti-error system for electronic work tickets for power lines according to claim 1, characterized in that, When an electronic work order for power lines containing fields such as "parameter testing" or "pressure application" is in the pending completion stage, the electronic work orders for power lines in the corresponding bundle that are in the pending approval stage will fail the safety verification of the associated anti-misoperation unit and will give an alarm to the work permit issuer.

6. The intelligent anti-error system for electronic work tickets for power lines according to any one of claims 3-5, characterized in that, The system's interlocking library supports manually adding key fields to enable the electronic work permit interlocking function for power lines. The electronic work permit interlocking function for power lines also supports manual deactivation after the work permit issuer has reviewed and approved it.

7. The intelligent anti-error system for electronic work tickets for power lines according to claim 1, characterized in that, The method for obtaining the field content in the electronic work order for power lines adopts OCR text recognition technology.

8. A method for intelligently preventing errors in electronic work permits for power lines, characterized in that, The system as described in claim 1 includes: S1. Electronic work orders for power lines undergo a three-level error prevention check before being signed off. Electronic work orders for power lines that pass the three-level error prevention check will have the signing function enabled; specifically... For the electronic work order for power lines that is in the pending acceptance stage, the fields of work line and work location are compared pairwise, and the two parts of the field content "**kVxx line" are extracted. If the two parts of the field content are completely consistent, the first level of error prevention verification is judged to be passed; among them, the "**" character is Arabic numeral, and the "xx" character is not restricted. For the electronic work order for power lines that is in the pending acceptance stage, the field content of the work line and work content is compared pairwise, and the two parts of the field content "**kVxx line" are extracted. If the two parts of the field content are completely consistent, the second level of error prevention verification is judged to be passed. For the electronic work tickets of power lines that are in the pending acceptance stage, the field contents of the work line and safety measures "name of the line bay that should be converted to maintenance status" are compared pairwise, and the two parts of the field contents "**kVxx line" are extracted. If the two parts of the field contents are completely consistent, the third level of error prevention verification is judged to be passed. After passing the three-level anti-misoperation verification check, the electronic work ticket for power lines will be enabled for signing. After the electronic work ticket for power lines is signed, step S2 will be executed. If any level of anti-misoperation verification fails, the system will lock the signing and issue an alarm. S2. Obtain the field content "**kV xx line" of the "Name of line bay to be converted to maintenance status" in the safety measures section of all electronic work tickets for power lines and compare it to establish the interrelationship of electronic work tickets for power lines; specifically, Retrieve the field content "**kVxx line" of the "Line bay name that should be transferred to maintenance status" in all electronic work orders for power lines and compare it; generate a bundle for each electronic work order for power lines with completely non-overlapping safety measures; if the field content "**kVxx line" in the "Line bay name that should be transferred to maintenance status" of multiple electronic work orders for power lines overlaps, then bundle them together, and the bundle is associated with multiple electronic work orders for power lines; when the electronic work order process for power lines reaches the final stage, remove the corresponding electronic work order for power lines from the bundle; S3. Obtain the field content of the work content in all electronic work orders for power lines within all bundles. When the field content of the work content of a certain electronic work order for power lines contains "parameter test" or "pressure increase", establish an anti-misoperation interlocking relationship for that electronic work order for power lines: When any electronic work order for power lines in any bundle is in the pending completion stage, electronic work orders for power lines with work content containing fields including "parameter test" or "pressure increase" will fail the safety verification of the associated anti-misoperation unit and will give an alarm prompt to the work permit holder; and when electronic work orders for power lines with work content containing fields including "parameter test" or "pressure increase" are in the pending completion stage, electronic work orders for power lines in the corresponding bundle that are in the pending permitting stage will fail the safety verification of the associated anti-misoperation unit and will give an alarm prompt to the work permit holder.
