Description

Technical Field

[0001] This invention relates to the field of joint review of work orders and operation tickets, and in particular to a method and terminal for joint review of multiple work orders and multiple operation tickets. Background Technology

[0002] During substation maintenance and operation, the safety measures section of the work order usually lists the relevant AC / DC power supplies, air switches, pressure plates, fuses, or control mode switching requirements that should be switched on or off, while the main body of the work order records the actual disconnection, closing, engagement, disengagement, or switching actions performed.

[0003] On-site, it is common to encounter situations where a single work task is associated with multiple work orders and multiple operation tickets. During manual verification, it is necessary to cross-check the numbers, names, and actions between the permission columns of multiple work orders and the text of multiple operation tickets. This can easily lead to the omission of a circuit breaker or pressure plate, or the operation ticket performing an action that was not required by the work order.

[0004] Simple full-text search can only determine if a number appears, but it cannot distinguish whether the operation ticket containing the number matches the keyword in the name, nor can it determine whether the action intent corresponds. For example, if the number appears on one operation ticket and the keyword in the equipment name appears on another operation ticket, a concatenated full-text search will mistakenly identify it as already covered. Therefore, a structured joint review method within a multi-ticket set is needed. Summary of the Invention

[0005] The purpose of this invention is to propose a joint review method and terminal for multiple work orders and multiple operation orders, which solves the technical problem of how to extract the requirements to be executed from the work order permit holder column, extract the actual execution actions from the operation order text, and perform two-way, same-issue evidence and action intent verification.

[0006] On the one hand, a method for joint review of multiple work orders and multiple operation orders is provided, including: Receive multiple work orders and multiple operation tickets pending joint review, locate the relevant AC / DC power supply clauses to be switched from each work order, extract the work order requirements, and extract the actual operation ticket items from the text of multiple operation tickets; The work order requirements and the actual operation order are normalized to obtain corresponding strict keys and soft keys; wherein, the normalization process includes at least number normalization, cabinet context normalization, and action intent normalization; the strict key is composed of component type, action intent, component number, and cabinet context; the soft key is composed of component type, action intent, and component number; The work order requirements and the actual operation order items are compared in both a forward and reverse manner to identify missing items that are required by the work order but not executed by the operation order, as well as redundant items that are executed by the operation order but not required by the work order. Verify the candidate options with matching numbers to determine whether the name keywords match within the same operation ticket evidence and whether the action intent matches within the window near the number. Output the joint review results based on the verification results.

[0007] Preferably, the work order requirements include at least the component type, action intent, component number, cabinet context, and source label.

[0008] Preferably, the actual items of the operation ticket include at least the component type, action intent, component number, cabinet context, and source label.

[0009] Preferably, the positioning of the relevant AC / DC power supply clauses to be switched includes obtaining the work order text information from each work order, identifying the work order information and relevant AC / DC power supply information to be switched in the area where the licensor is responsible for safety measures, as well as the positioning of the corresponding adjacent numbered clause boundaries.

[0010] Preferably, the requirements for extracting work tickets include at least extraction by number and name row, extraction by parallel device after colon, extraction by multiple items in a row, and extraction by natural language action device.

[0011] Preferably, the extraction of actual items from the operation ticket includes at least the following: dividing the operation ticket text by line or by delimiter, and extracting the relevant numbers of the pressure plate, air switch, QK switching handle, remote / local control mode, and control power supply.

[0012] Preferably, determining whether the name keyword is hit within the same operation ticket evidence includes judging whether the number appears in the text of a certain operation ticket, and the name keyword or line voltage keyword of the work ticket requirement item is hit within the text of the same operation ticket, so as to avoid misjudgment and overwriting caused by the number being in the first operation ticket and the name being in the second operation ticket.

[0013] Preferably, determining whether the action intent is matched in the window near the number includes searching for the corresponding action word in a preset text window near the component number based on the intent to disconnect, close, engage, exit, switch to local or switch to remote in the work order requirements.

[0014] Preferably, when the work order permitter column contains a parallel clause that switches the switch control mode selection ZK for multiple equipment numbers to local or remote, the parallel equipment numbers are extracted one by one, and it is verified whether the corresponding number operation exists in the text of multiple work orders.

[0015] On the other hand, a terminal for joint review of multiple work orders and multiple operation tickets is also provided, for the aforementioned joint review method of multiple work orders and multiple operation tickets, including: The terminal receives multiple work orders and multiple operation tickets pending joint review, locates the relevant AC / DC power supply clauses to be switched from each work order, extracts the work order requirements, and extracts the actual operation ticket items from the text of the multiple operation tickets. The terminal performs normalization processing on the work order requirements and the actual operation order items to obtain corresponding strict keys and soft keys; wherein, the normalization processing includes at least number normalization, cabinet context normalization, and action intent normalization; the strict key is composed of component type, action intent, component number, and cabinet context; the soft key is composed of component type, action intent, and component number; The terminal performs forward and reverse comparisons between the work order requirements and the actual operation order items to identify missing items that are required by the work order but not executed by the operation order, as well as redundant items that are executed by the operation order but not required by the work order. The terminal verifies the candidate items matched by the number, determines whether the name keywords are matched within the same operation ticket evidence, and determines whether the action intent is matched within the window near the number, and outputs the joint review result based on the verification results.

[0016] In summary, implementing the embodiments of the present invention has the following beneficial effects: The method and terminal for joint review of multiple work orders and multiple operation tickets provided by this invention can process multiple work orders and multiple operation tickets simultaneously, adapting to the scenario of multiple tickets being associated in actual maintenance tasks. Through structured extraction of the permitter field, AC / DC power supply, pressure plate, and control mode requirements are transformed into comparable items. Through bidirectional comparison of forward missing and reverse redundant requirements, it can detect both unexecuted work order requirements and unexecuted operation ticket requirements. By using keyword matching constraints for the number and name within the same operation ticket, it avoids misjudgments caused by full-text search of multiple tickets. Through verification using the window near the action intent and ZK parallel number coverage, it improves the ability to identify control mode switching and action omissions. Attached Figure Description

[0017] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, obtaining other drawings based on these drawings without creative effort still falls within the scope of the present invention.

[0018] Figure 1 This is a schematic diagram of the main process of a joint review method between multiple work orders and multiple operation orders in an embodiment of the present invention. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 The diagram shown is an embodiment of a method for joint review of multiple work orders and multiple operation orders provided by the present invention. In this embodiment, the method includes the following steps: Step S1: Receive multiple work orders and multiple operation tickets to be jointly reviewed, locate the relevant AC / DC power supply clauses to be switched from each work order, and extract the work order requirements; and extract the actual operation ticket items from the text of the multiple operation tickets. Step S2: Normalize the work order requirements and the actual operation order items to obtain the corresponding strict keys and soft keys; wherein, the normalization process includes at least number normalization, cabinet context normalization, and action intent normalization; the strict key is composed of component type, action intent, component number, and cabinet context; the soft key is composed of component type, action intent, and component number. Step S3: Perform a forward comparison and a reverse comparison between the work order requirements and the actual operation order items to identify missing items that are required by the work order but not executed by the operation order, as well as redundant items that are executed by the operation order but not required by the work order. Step S4: Verify the candidate options with matching numbers, determine whether the name keywords match within the same operation ticket evidence, and determine whether the action intent matches within the window near the number. Output the joint review result based on the verification results.

[0021] In one embodiment, the work order requirements include at least the component type, action intent, component number, cabinet context, and source label. The operation ticket actual items include at least the component type, action intent, component number, cabinet context, and source label. Multiple work orders and multiple operation tickets are received, and the two types of tickets are respectively categorized into a work order set and an operation ticket set as input for joint review.

[0022] In one embodiment, locating the relevant AC / DC power supply clauses to be switched includes obtaining the work order text information from each work order, identifying the work order holder's responsible information and the relevant AC / DC power supply information to be switched in the area where the licensor is responsible for safety measures, and locating the boundaries of the corresponding adjacent numbered clauses. The licensor's responsible safety measures area in each work order is located, and the relevant AC / DC power supply clauses to be switched are extracted.

[0023] In one embodiment, the extraction of work order requirements includes at least extraction by number and name row, extraction by parallel devices after a colon, extraction by multiple parallel items in one row, and extraction by natural language action devices. Requirements such as air switches, pressure plates, fuses, control power supplies, operating power supplies, and control mode switching are extracted from the work order terms.

[0024] In one embodiment, the extraction of actual items from the operation ticket includes at least splitting the operation ticket text by line or by delimiter and extracting the relevant numbers for the pressure plate, air switch, QK (air switch) switch handle, remote / local control mode, and control power supply. The executed actions for the pressure plate, air switch, QK switch handle, and control mode are then extracted from the operation ticket text.

[0025] In one embodiment, determining whether the name keyword matches within the same operation ticket evidence includes judging whether the number appears in the text of a certain operation ticket, and whether the name keyword or line voltage keyword of the work ticket requirement matches within the text of the same operation ticket, to avoid misjudgment and overwriting caused by the number being in the first operation ticket while the name is in the second operation ticket. Determining whether the action intent matches within the window near the number includes searching for the corresponding action word in a preset text window near the component number based on the disconnect, close, engage, exit, switch to local or switch to remote intent in the work ticket requirement. The requirement items and actual items are normalized by number, action, cabinet, and type to form strict keys and soft keys. A forward comparison is performed to output missing items that are required by the work ticket but whose corresponding operations are not found in multiple operation tickets. A reverse comparison is performed to output redundant items that exist in multiple operation tickets but are not required by the work ticket. For the numbered matching items, further checks are performed on same ticket name keyword matching, action intent near window matching, and ZK (changeover switch) parallel numbering overwriting.

[0026] In one specific embodiment, multiple work tickets and multiple operation tickets are received simultaneously, and the two types of tickets are respectively classified into a work ticket set and an operation ticket set as input for joint review.

[0027] The work order text identifies the area where the permitter is responsible for safety measures, and extracts several work order requirements from the clause "relevant AC / DC power supplies to be switched".

[0028] The operation ticket text is segmented by line or delimiter, and the actual action items such as pressure plate, air switch, QK switching handle and control mode switching are extracted and formed into a comparable key.

[0029] Use strict keys to perform bidirectional comparisons. Output missing items when a work order requirement does not exist in the actual operation ticket; output redundant items when an actual operation ticket requirement does not exist in the work order requirement.

[0030] In addition to matching the number, it is further required that the name keywords and the intention of the action match within the same operation ticket evidence; for ZK parallel numbering clauses, the terminal checks one by one whether each number is covered by the operation ticket.

[0031] The terminal can perform the above steps based on local structured tables, invoice text, standard ledgers, rule bases, or invoice collections. When outputting the audit results, the terminal can simultaneously record the hit steps, hit invoices, compared invoices, rule tags, and review levels to facilitate on-site personnel location and review.

[0032] An embodiment of the present invention also provides a terminal for joint review of multiple work orders and multiple operation tickets, for implementing the aforementioned joint review method for multiple work orders and multiple operation tickets, including: The terminal receives multiple work orders and multiple operation tickets pending joint review, locates the relevant AC / DC power supply clauses to be switched from each work order, extracts the work order requirements, and extracts the actual operation ticket items from the text of the multiple operation tickets. The terminal performs normalization processing on the work order requirements and the actual operation order items to obtain corresponding strict keys and soft keys; wherein, the normalization processing includes at least number normalization, cabinet context normalization, and action intent normalization; the strict key is composed of component type, action intent, component number, and cabinet context; the soft key is composed of component type, action intent, and component number; The terminal performs forward and reverse comparisons between the work order requirements and the actual operation order items to identify missing items that are required by the work order but not executed by the operation order, as well as redundant items that are executed by the operation order but not required by the work order. The terminal verifies the candidate items matched by the number, determines whether the name keywords are matched within the same operation ticket evidence, and determines whether the action intent is matched within the window near the number, and outputs the joint review result based on the verification results.

[0033] In summary, implementing the embodiments of the present invention has the following beneficial effects: The method and terminal for joint review of multiple work orders and multiple operation tickets provided by this invention can process multiple work orders and multiple operation tickets simultaneously, adapting to the scenario of multiple tickets being associated in actual maintenance tasks. Through structured extraction of the permitter field, AC / DC power supply, pressure plate, and control mode requirements are transformed into comparable items. Through bidirectional comparison of forward missing and reverse redundant requirements, it can detect both unexecuted work order requirements and unexecuted operation ticket requirements. By using keyword matching constraints for the number and name within the same operation ticket, it avoids misjudgments caused by full-text search of multiple tickets. Through verification using the window near the action intent and ZK parallel number coverage, it improves the ability to identify control mode switching and action omissions.

[0034] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
