[0036] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] The present invention provides a precise and automatic ticket checking system for switching operation tickets, comprising:

[0038] Expert module, the expert module includes a translator, an inference engine, a rule base and a knowledge base; the knowledge base and the rule base are used to store the operation ticket information and ticket review rules set in advance by relevant professionals;

[0039] The inference engine is connected with the knowledge base and the rule base data, and based on the operation ticket information and ticket review rules in the knowledge base and the rule base, obtains the current operation ticket information review status and the character language of the professionals corresponding to the relevant professional requirements through logical analysis, pattern matching and association retrieval; the translation machine is used to translate the character language obtained by the inference engine into machine language through a professional vocabulary mapping table, grammar conversion rules or semantic understanding model mechanism;

[0040] A user interface module, which includes a system software interface, is used to receive operation ticket information that needs to be checked by a user, and provides a window and operation instructions for input and modification, through which a user can input operation ticket information, and the operation instructions include but are not limited to checking and printing;

[0041] A ticket review module, which is data-connected with the expert module and the user interface module, reviews the operation ticket received by the user interface module based on the machine language information of the expert module to obtain the reviewed operation ticket;

[0042] An operation ticket management module, which is data-connected to the ticket review module, includes an information display unit, a printing unit, a saving unit, a reading unit, a modification unit, and a generation unit, and is used to operate the ticket review calculation results of the ticket review module, including but not limited to the creation, saving, and printing of operation ticket files.

[0043] Embodiment 1:

[0044] like Figure 1-7 As shown, in this embodiment;

[0045] System interface overview: ticket number, operation task, remarks, operation ticket text box, ticket review, print, save, read, generate, clear, etc. Substation name, ticket number, operation task, remarks: used to fill in the basic information of the dispatching operation ticket, which is consistent with the format of the intranet system, which is convenient for operators to operate directly and improves work efficiency. Operation ticket text box: used to enter the operation task of the operation ticket, and provides the following operation task input and modification windows:

[0046] Ticket review: After clicking the button, the system checks whether the operation task is correct;

[0047] Print: Print the operation ticket that has been reviewed;

[0048] Save: store the operation ticket in a computer folder;

[0049] Read: Extract the operation task file in the computer to the operation ticket text box.

[0050] The specific operation process of this system is as follows:

[0051] First, the staff opens the PMS system and finds the written operation ticket in the new ticket box in the PMS system, and then modifies the operation ticket according to the needs. If there is no modification, directly open the system software interface in the user interface module, corresponding to Figure 2 The staff will then copy the operation ticket information in the PMS system to the corresponding module of the system, including the operation ticket name, operation ticket number and operation task of the operation ticket, and then review the operation ticket content through the ticket review module.

[0052] The ticket review module assumes that the element set in the operation ticket information is E(E1, E2, E i ,...,E n ), where E irepresents the i-th element in the operation ticket, and n represents the total number of elements in the operation ticket information;

[0053] Suppose the set of ticket review rules is R(R1,R2,R j ,...,R m ), where R j represents the jth ticket review rule, and m represents the total number of ticket review rules in the ticket review rule set;

[0054] For each element E i and each voting rule R j , define a matching function M(E i ,R j ):

[0055]

[0056] Define a weight vector W(W1,W2,W j ,...,W m ), where W j Representation rule R j The importance weight of the ticket review rules can be set in advance by professionals through the expert module when storing the ticket review rules in advance, and the following requirements are met:

[0057]

[0058] The error probability value P of the operation ticket is calculated by the following formula:

[0059]

[0060] The error probability value of each operation ticket is calculated in turn, and the completely correct operation ticket is output according to the probability to obtain the correct operation ticket after ticket review.

[0061] Through the intelligent algorithm of the ticket review module, the automatic review of the operation ticket content is realized, reducing the need for manual review, thereby improving the accuracy and processing efficiency of the operation ticket. At the same time, it can accurately identify potential errors, effectively reduce the error rate in the operation ticket, and enhance the accuracy and safety of the operation.

[0062] After the ticket review is completed, a question window will pop up on the system software interface. If there is a problem, the corresponding content will be displayed in the window. If there is no problem, a blank box will pop up;

[0063] If there are no problems, the staff can select the printing unit or saving unit as needed to print out the operation ticket data for archiving and actual operation, or save the operation ticket data in word document format for subsequent analysis and statistics.

[0064] If there is a problem, the staff will make modifications in the PMS system based on the content of the problem, and then repeat the above steps to complete the operation ticket data statistics. Through the ticket review module, it is possible to automatically analyze the operation content in the operation ticket, detect potential errors, and provide warnings and suggestions to reduce the error rate.

[0065] In addition, if the operation ticket data is stored in a word document format, the document data can be read by the reading unit so that the data is automatically filled in the corresponding module, and then reviewed by the ticket review module to determine whether there are any problems with the content.

[0066] If errors are found in the operation ticket data after printing, the operation ticket data can be generated into a table through the modification unit and presented through Excel software. The staff can make direct modifications in the Excel software without having to make modifications in the PMS system, thereby improving work efficiency and improving the fault tolerance of the system and avoiding duplication of work. When errors occur during the data application process, the staff can also make direct modifications in the Excel table without having to make modifications again in the PMS system, thereby optimizing the workflow and improving work efficiency.

[0067] Example 2: In this example, the user enters the correct operation ticket;

[0068] By setting the operation task of the operation ticket to "110kV ferry line 113 switch partial protection pressure plate input and exit position switch", the correct operation task can be obtained, as shown in the following table:

[0069] Table 1 Operation steps

[0070]

[0071] By reviewing the above operation tasks, we can get the correct ticket review results, such as Figure 5 As shown;

[0072] Example 3: In this example, the user inputs the missing operation ticket of the operation object;

[0073] Deleting the monitoring backend machine, the operation object of step 3 and step 4 in Table 1 of Example 2, can obtain the following report, such as Figure 6 As shown, due to the lack of operation objects, the operation ticket is identified as an unqualified operation ticket, and the system issues a prompt, suggesting that the operation ticket be modified.

[0074] Example 4: In this example, the user enters an operation ticket with an incorrect operation sequence;

[0075] By exchanging step 3 and step 5 in Table 1 of Example 2, the following report can be obtained: Figure 7As shown, after the steps are swapped, the system identifies the logical errors in the corresponding steps, issues an operation ticket error reminder, and prompts the dispatcher to make modifications.

[0076] The automated audit process significantly speeds up the audit process, shortens the processing time, and improves work efficiency. In addition, the present invention supports the rapid generation and printing of operation tickets, further improving the compilation efficiency. At the same time, operation and maintenance personnel can easily save and print operation tickets, which is convenient for subsequent statistical analysis and management work, ensuring the flexibility and practicality of operation tickets.

[0077] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
