[0040] Furthermore, the data processing unit includes a filter, a signal amplifier and an analog-to-digital converter, the filter is used to filter the input signal, the signal amplifier is used to amplify the input signal, and the analog-to-digital converter is used to convert the format of the input signal.

[0041] Furthermore, the user instruction data processing module includes a binary input matching unit, a calculation unit, a feedback unit, and a connection signal adjustment unit. The search unit is used to extract required data from the storage module, the binary input matching unit is used to match the binary input name input by the user with the data in the storage module, the feedback unit is used to output feedback information to the display module according to the matching result of the binary input matching unit, and the connection signal adjustment unit is used to send a connection signal to the internal switch according to the matching result of the binary input matching unit.

[0042] Specifically, the connection signal adjustment unit changes the connection status between each interface and each internal circuit by sending different connection signals to the internal switch.

[0043] Furthermore, the working process of the device includes the following steps:

[0044] S1, the staff inputs the name of the input quantity through the command input module.

[0045] S2, the user instruction data processing module adjusts the connection relationship between each interface and the internal circuit according to the name of the input quantity input by the user.

[0046] S3, the relevant output signals of each relay protection device and the output matrix are input into the processing module through the signal input module.

[0047] S4, the input signal data processing module processes and analyzes the received input signal.

[0048] S5, the display module displays the analysis results, and the storage module stores the analysis results.

[0049] Furthermore, the user instruction data processing module adjusts the connection relationship between each interface and the internal circuit, including the following steps:

[0050] S21, the binary input matching unit matches the binary input name input by the user with the data in the storage module to determine whether a corresponding matching result can be found. If so, execute S26, otherwise, execute S22.

[0051] Specifically, the matching result includes a binary input name and an internal circuit for detecting the binary input corresponding to the binary input name.

[0052] S22, calculating the matching similarity index between the inputted input name and each input name stored in the storage module according to the input name and the data in the storage module.

[0053] Specifically, by obtaining the matching similarity index, it is helpful for the staff to correctly connect the interface and the internal circuit when the name is entered incorrectly; at the same time, when the staff enters a new input name, it is helpful to obtain the internal circuit that is most suitable for connecting to the interface of the new input based on the matching similarity between the new input name and the existing input name.

[0054] Specifically, the matching similarity index can be calculated according to the following steps:

[0055] STEP1. Eliminate the numeric part in the input quantity name to reduce the impact of numbers on the calculation, and use the input input quantity name as the field to be identified.

[0056] STEP2, match the field to be identified with the words in the dictionary. If successful, execute STEP5, otherwise, execute STEP4.

[0057] Specifically, the dictionary contains all nouns related to the power system and power system detection.

[0058] STEP4, remove the last character from the field to be identified, obtain a new field to be identified, and return to STEP2.

[0059] Specifically, when there is only one character left in the field to be identified and the character cannot be matched with a word in the dictionary, the character is treated as a separate word.

[0060] STEP5, remove the field to be identified from the field to be identified as a segmented field, and return to STEP2 until all the characters in the input input quantity name are segmented into words.

[0061] Specifically, through the above differences, the input name of the input quantity can be divided into multiple words with specific meanings. For example, if the staff makes a mistake when entering the name of the input quantity, and enters "locking low pressure branch standby head" (when entered correctly, it is "locking low pressure branch standby investment", which will be divided into "locking", "low pressure", "branch", "standby investment"), it will be divided into "locking", "bottom", "pressure", "branch", "standby", and "head"; through this method, the possible meanings of the words included in the input name of the input quantity can be obtained, such as the "branch" in "locking low pressure branch standby head" can be matched with the "branch" in the dictionary, and the "branch" and "branch" with similar meanings to "branch" can be obtained in the dictionary. For example, the "standby investment" in "locking low pressure branch standby head" can be matched with the "standby investment" in the dictionary, and the "standby investment" with similar meanings to "standby investment" can be obtained in the dictionary.

[0062] Specifically, this method can also divide the stored input quantity names into multiple words with specific meanings; by dividing the stored input quantity names into words, it is helpful to match the stored input quantity names with the parts of the input input quantity names with the same meaning.

[0063] STEP6, obtain the matching similarity index between the input binary input name and each stored binary input name according to the following formula:

[0064]

[0065] Wherein, zb is the matching similarity index, X is the number of words that are completely matched in the words included in the input input name, and a complete match means that there are words that are exactly the same as it in the words included in the stored input name, Y is the number of words that only match the meaning of the words included in the input input name, and a meaning-only match means that there are words that have the same meaning but are not completely matched in the words included in the stored input name, Z is the number of words that cannot be matched in the words included in the input input name, and Px is the number of characters contained in the xth fully matched word of the input variable name, P y is the number of characters contained in the yth word that matches only the meaning of the input variable name, P z is the number of characters contained in the zth unmatched word in the input variable name, k1 is P x The influence weight of y The influence weight of z The influence weight of .

[0066] The following is the procedure to obtain the matching similarity index:

[0067]

[0068]

[0069] Specifically, k1, k1, and k3 can be obtained as follows;

[0070]

[0071] Among them, NUM is the number of characters contained in the input variable name, num is the number of characters contained in the stored input variable name, e is a natural constant, p is y The name of the stored input quantity is the same as P y The number of characters contained in the corresponding word, ZONG is the number of characters that cannot be matched in the input variable name.

[0072] Specifically, by introducing word meanings for matching and calculating matching similarity indicators, matching deviations caused by synonyms or near-synonyms are avoided, which is conducive to improving the success rate of matching.

[0073] S23, determining whether there is a matching similarity index greater than a similarity index threshold value among the matching similarity indexes, if so, executing S24, otherwise, executing S25.

[0074] Specifically, the similarity index threshold is set by those skilled in the art according to the required similarity accuracy. The larger the threshold, the higher the accuracy.

[0075] S24, taking the data in the storage module corresponding to the maximum value in the matching similarity index as the matching result corresponding to the input input quantity name, and executing S26.

[0076] S25, the display module displays a warning signal, and the staff manually adjusts the internal switch through the command input module, and ends.

[0077] S26, the connection signal adjustment unit sends a connection signal to the internal switch according to the matching result.

[0078] Specifically, the connection signal adjustment unit controls the opening and closing of different internal switches by sending connection signals to internal switches. By controlling the opening and closing of different internal switches, different interfaces can be connected to different internal circuits, and different internal circuits are used to realize different functions. According to the matching result, the interface of the binary input quantity and the internal circuit used to detect the binary input quantity are connected, so that corresponding detection of the binary input quantity can be realized according to the binary input quantity name.

[0079] The beneficial effects of this solution are as follows: 1. By setting up a binary input matching unit and a connection signal adjustment unit, it is helpful to connect the interface corresponding to the binary input to different internal circuits according to the input binary input name, thereby realizing different functions, which is beneficial for the staff to customize the binary input.

[0080] 2. By setting the matching similarity index, it is helpful to judge whether the input input name is similar to the data stored in the storage module based on the index. When the matching similarity index is greater than a certain level, the data stored in the storage module is used as the corresponding matching result, which is helpful to increase the probability of successful matching and connect the interface corresponding to the input quantity to different internal circuits as soon as possible to avoid affecting the work progress due to missed or wrong input by the staff.

[0081] Embodiment 2: This embodiment should be understood to include all the features of any of the above embodiments, and further improve on the above embodiments, and also include a preferred calculation method for the matching similarity index, which is calculated by the following formula:

[0082]

[0083] Wherein, ZB is the matching similarity index between the currently inputted input quantity name and the stored input quantity name after preferred calculation, zb is the matching similarity index between the currently inputted input quantity name and the stored input quantity name obtained in the manner of Embodiment 1, DIS is the edit distance between the inputted input quantity name and the stored input quantity name, and the edit distance can be obtained through the prior art, I is the number of groups of past matching data stored in the storage module for calculating ZB, and the value of the number of groups can be 50 to 100. The larger the value, the higher the calculation accuracy but the slower the calculation speed, zb i is the matching similarity index obtained in the manner of Example 1 in the i-th group of past data, DIS i is the edit distance between the input name of the input quantity and the stored name of the input quantity in the i-th group of past matching data, CS is the cosine similarity between the input name of the input quantity and the stored name of the input quantity, and the cosine similarity can be obtained through the existing technology, DIS iis the cosine similarity between the input variable name in the i-th group of past matching data and the stored input variable name;

[0084] MIS is the error parameter. The larger the parameter is, the greater the error between the various similarity judgment methods is. When the error parameter is less than the error parameter threshold, the error between the various similarity judgment methods is considered to be small, and ZB is used as the final matching similarity indicator. When the error parameter is greater than the error parameter threshold, the error between the various similarity judgment methods is considered to be large, which will reduce the accuracy of the matching. At this time, zb is used as the final matching similarity indicator.

[0085] in, Figure 4 is a scatter plot of the relationship between ZB and zb, DIS and CS. The scatter plot is obtained based on the following limiting conditions: and

[0086] Specifically, by introducing past matching data, it is helpful to obtain the difference between the analysis results of different similarity judgment methods when analyzing past data and the matching similarity index in Example 1, reduce the errors caused by different judgment methods, and help further integrate various judgment methods to improve the ability of the matching similarity index to characterize similarity.

[0087] The beneficial effects of this embodiment are as follows: by fusing multiple ways of representing text similarity to obtain a matching similarity index, it is beneficial to further improve the matching similarity index's ability to represent the similarity between the input input quantity name and the stored input quantity name, thereby reducing the matching error caused by errors in word meaning recognition.
