[0037] To make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] The synthetic signal generation method provided by the embodiments of the present application can be applied to an application environment as Figure 1 shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or can be placed in the cloud or other network servers. The synthetic signal generation method provided by the embodiments of the present application can be executed independently by the terminal 102 or the server 104, or can be executed collaboratively by the terminal 102 and the server 104.

[0039] Taking the collaborative execution of the terminal 102 and the server 104 as an example for illustration, in one embodiment, the terminal 102 sends a detection information table about the substation to the server 104. The detection information table includes multiple first measurement point descriptions. The server 104 obtains a substation configuration description file, and the substation configuration description file includes multiple second measurement point descriptions; for each first measurement point description, if it is verified that there is no second measurement point description in the substation configuration description file that matches the first measurement point description, the server 104 determines multiple candidate synthetic signal templates; based on the first measurement point description, a matching target synthetic signal template is selected from the multiple candidate synthetic signal templates; the server 104 determines a signal synthesis method and at least one target source signal corresponding to the first measurement point description based on the target synthetic signal template, and generates a target synthetic signal that matches the first measurement point description based on the signal synthesis method and the at least one target source signal. The target synthetic signal is used for remote control and detection.

[0040] Among them, the terminal 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, etc. The server 104 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0041] In an exemplary embodiment, as Figure 2 shown, a synthetic signal generation method is provided. Taking this method applied to a computer device (which can be the terminal 102 or the server 104) as an example for illustration, it includes the following steps 202 to step 208. Among them:

[0042] Step 202, obtain a detection information table about the substation and a substation configuration description file. The detection information table includes multiple first measurement point descriptions, and the substation configuration description file includes multiple second measurement point descriptions.

[0043] Among them, the detection information table of the substation is issued by the dispatching. The detection information table records the measurement and control devices required for remote control and detection by the dispatching. It can be understood that the detection information table includes multiple first measurement point descriptions. The first measurement point description refers to the measurement point description in the detection information table. The measurement point description includes the device name of the measurement and control device for remote control and detection and the status description of the measurement and control device. The measurement point description is used to describe the measurement points deployed in the corresponding measurement and control device. At least one measurement point is deployed in each measurement and control device. The measurement points can be telemetry, tele-signaling, tele-control, and tele-pulse measurement points. The status description is used to reflect whether the measurement and control device is abnormal or the type of abnormality that occurs.

[0044] The substation configuration description file (SCD, Substation Configuration Description) is used to describe the configuration information of the substation. The substation configuration description file covers the overall situation of the substation, the detailed parameters and functions of the measurement and control devices and logical nodes, the communication network settings, the automation system function configuration, etc. In one embodiment, the substation configuration description file includes multiple second measurement point descriptions and the remote control configuration description information of each second measurement point description. The remote control configuration description information reflects the configuration parameters required for the corresponding measurement and control device to perform remote control and detection. For example, the signal type of the signal collected by the measurement and control device when performing remote control and detection. The second measurement point description refers to the measurement point description in the substation configuration description file.

[0045] Exemplarily, the computer device obtains the detection information table to be processed and the substation configuration description file to be processed, and preprocesses the measurement point descriptions in the detection information table to be processed and the substation configuration description file to be processed respectively to filter out the measurement point descriptions with non-standard naming and formats, obtaining the preprocessed detection information table and the preprocessed substation configuration description file, and performing the following step 204 based on the preprocessed detection information table and the preprocessed substation configuration description file.

[0046] Step 204, for each first measurement point description, if it is verified that there is no second measurement point description in the substation configuration description file that matches the first measurement point description, determine multiple candidate composite signal templates.

[0047] Among them, the candidate synthetic signal template is the synthetic signal template to be screened. The synthetic signal template is a template for generating synthetic signals. The synthetic signal template includes the keyword of the synthetic signal name, the signal synthesis method, the synthetic signal type, and the source signal name of the source signal of the synthetic signal. Among them, the keyword of the synthetic signal name can be "total accident", "time synchronization anomaly", etc.; the signal synthesis methods include: AND, OR, XNOR, XOR, single-point synthesis into double-point, double-point decomposition into single-point, etc.; the synthetic signal types include substation-wide synthetic signals and interval synthetic signals. For example, the total accident signal needs to be synthesized from the accident signals of all intervals, so the type is a synthetic signal. The substation-wide synthetic signal refers to the sum of the interval signals of all intervals, and the interval synthetic signal refers to the signal synthesized from the source signals of a single interval. An interval is a component unit of a substation, and there are corresponding measurement and control devices in the interval. The time synchronization anomaly of the interval measurement and control device (the measurement and control device of a single interval) is synthesized from the three signals of "time jump detection status anomaly", "time synchronization signal status anomaly", and "time synchronization service status anomaly" in the current interval. Generally speaking: the signal that needs to be synthesized using cross-interval source signals is a substation-wide synthetic signal, and the signal that only needs to be synthesized from the source signals in a single interval is an interval synthetic signal. The source signal of the synthetic signal is the signal used to synthesize the signal. The source signal of the synthetic signal is the signal obtained by detecting the measurement and control device by the measurement point deployed in the measurement and control device. Therefore, it can be understood that there is at least one associated source signal of the synthetic signal for each measurement and control device.

[0048] Optionally, for each first measurement point description, when the computer device fails to query a second measurement point description that matches the first measurement point description from all the second measurement point descriptions in the substation configuration description file, the computer device obtains a pre-set synthetic signal template. The computer device can set each synthetic signal template as a candidate synthetic signal template, or screen out the synthetic signal templates that match the first measurement point description from multiple synthetic signal templates, and use the screened synthetic signal templates as candidate synthetic signal templates.

[0049] Exemplarily, for each first measurement point description, check whether there is a second measurement point description that is consistent with the first measurement point description in the substation configuration description file. If it exists, the consistent second measurement point description matches the first measurement point description. If it does not exist, it is determined that there is no second measurement point description that matches the first measurement point description. For example, perform word segmentation on the first measurement point description and each second measurement point description. If there is a second measurement point description where the word segmentation at each position is the same or synonymous with the word segmentation at the corresponding position in the first measurement point description, and the number of word segments of the first measurement point description and the second measurement point description is the same, then it is considered that the second measurement point description is consistent with the first measurement point description; otherwise, they are inconsistent.

[0050] In one embodiment, determining a plurality of candidate synthesis signal templates includes: obtaining a plurality of preset synthesis signal templates, where each synthesis signal template has a corresponding priority; and screening out candidate synthesis signal templates belonging to a preset priority from the plurality of synthesis signal templates.

[0051] In one embodiment, the priority of the synthesis signal template is determined based on the source signal name of the synthesis signal source signal involved in the synthesis signal template. The more the number of source signal names, the higher the priority of the corresponding synthesis signal template. In another embodiment, the priority of the synthesis signal template can be determined according to historical synthesis information. Determine the matching times of each synthesis signal template from the historical synthesis information, and determine the priority of each synthesis signal template according to the matching times. The higher the matching times, the higher the priority of the synthesis signal template; determine the priority of each synthesis signal template according to the respective times thresholds corresponding to each priority.

[0052] Optionally, after the computer device obtains a plurality of preset synthesis signal templates, it screens out the synthesis signal template with the highest priority from the plurality of synthesis signal templates, and uses the synthesis signal template with the highest priority as the candidate synthesis signal template.

[0053] Optionally, when the target synthesis signal template screened out in the previous time fails to match the first measurement point description, the computer device obtains the synthesis signal template with the second highest priority as the candidate synthesis signal template, and returns to step 206 below to continue execution. The priority of the target synthesis signal template screened out for the first time is the highest.

[0054] In this embodiment, according to the priority of the synthesis signal template, pre-screening can be performed from a large number of synthesis signal templates, reducing the subsequent template matching quantity and improving the generation efficiency.

[0055] Step 206, based on the first measurement point description, screen out a matching target synthesis signal template from the plurality of candidate synthesis signal templates.

[0056] Optionally, the computer device performs word segmentation on the first measurement point description to determine the status description in the first measurement point description, and performs word segmentation on each candidate synthesis signal template to determine the keywords of the synthesis signal in the candidate synthesis signal template. The computer device matches the keywords in each candidate synthesis signal template with the status description of the first measurement point description, and uses the candidate synthesis signal template to which the keyword matching the status description belongs as the target synthesis signal template.

[0057] Exemplarily, based on the first dictionary corresponding to the detection information table, perform word segmentation on the first measurement point description to obtain the first word segmentation. Based on the second dictionary corresponding to the synthesis signal template, perform word segmentation on each candidate synthesis signal template to obtain the second word segmentation.

[0058] For example: Based on each word and its word order in the description of the first measurement point, multiple candidate words are generated. For a candidate word w, the left entropy of the candidate word w is calculated using the following formula :

[0059] (1)

[0060] where represents the set of possible contexts that may appear on the left side of the candidate word w, that is, the set composed of all words or phrases that may appear on the left side of the candidate word w in the text. is the context in the context set. refers to the relative frequency of the context c1 and the candidate word w, expressed as: . For example, in the text “Do you eat apples? I want to eat apples. Let's buy apples together”, for the word “apples”, the context set on the left side is {eat, buy}. Then, the number of times “eat” appears on the left side of “apples” is 2, and the number of times “buy” appears on the left side of “apples” is 1. Then, P(eat) = 2 / 3. Similarly, the right entropy of the candidate word w is calculated using the following formula :

[0061] [[ID=2�]] (2)

[0062] where represents the set of possible contexts that may appear on the right side of the candidate word w, that is, the set composed of all words or phrases that may appear on the right side of the candidate word w in the text. is the context in this context set. refers to the relative frequency of the context c2 and the candidate word w, expressed as: .

[0063] It should be noted that the left entropy is used to measure the uncertainty of the context distribution on the left side of the candidate word w, and the right entropy is used to measure the uncertainty of the context distribution on the right side of the candidate word w.

[0064] After calculating the left entropy and right entropy of each candidate word w in the description of the first measurement point, the left entropy and right entropy are fused to obtain a fused entropy value. Based on the comparison result between the fused entropy value and the fusion threshold, it is determined whether the candidate word w can be used as the first segmentation word, that is, whether the candidate word w is a word. If so, the candidate word w is put into the first dictionary until the above process is completed for the last candidate word, and the completed first dictionary is obtained.

[0065] For the generation of the second dictionary, the process referring to the above first dictionary can be adopted, which will not be elaborated here.

[0066] In one embodiment, screening for a matching target synthetic signal template from multiple candidate synthetic signal templates based on the first measurement point description includes: for each candidate synthetic signal template, obtaining keywords of the synthetic signal name from the candidate synthetic signal template; comparing the first measurement point description with the keywords of each candidate synthetic signal template respectively to obtain keywords that are consistent with the first measurement point description, and using the candidate synthetic signal template corresponding to the keywords that are consistent with the first measurement point description as the target synthetic signal template that matches the first measurement point description.

[0067] Exemplarily, after determining the status description of the first measurement point description and the keywords of each candidate synthetic signal template, check whether there are keywords that are the same as the status description. If so, use the candidate synthetic signal template to which the same keywords belong as the target synthetic signal template. If not, obtain the first synonymy library between the first measurement point description and the synthetic signal template to check whether there are keywords that have a synonymous relationship with the status description. If so, use the candidate synthetic signal template to which the keywords with a synonymous relationship belong as the target synthetic signal template.

[0068] Illustrative example: The step of determining the first synonymy library includes: using the word segmentation of each first measurement point description as the first word segmentation, and using the word segmentation of each synthetic signal template as the second word segmentation. For each first word segmentation, the computer device calculates the edit distance (Levenshtein distance) between the first word segmentation and each second word segmentation respectively. When the minimum edit distance is less than the distance threshold, use the second word segmentation corresponding to the minimum edit distance as the synonym of the first word segmentation, that is, the second word segmentation corresponding to the minimum edit distance has a synonymous relationship with the first word segmentation, and store the first word segmentation and the second word segmentation with a synonymous relationship correspondingly in the first synonymy library until it is determined whether there is a second word segmentation with a synonymous relationship for the last first word segmentation. Among them, the edit distance represents the minimum number of operations required to transform one word into another word, including inserting, deleting, and replacing characters. If the edit distance between two words is small, it means that they are relatively similar in form and may also be relatively close in semantics. Exemplarily, the edit distance can be calculated according to the following formula (3):

[0069] (3)

[0070] Among them, D(A,B) is the Levenshtein distance (i.e., the minimum number of edit operations) between the string A and the string B. |A| is the length of the string A. |B| is the length of the string B. In this embodiment, the string A is the first word segmentation, and the string B is the second word segmentation. is the edit distance between two strings, and its value range is [0,1]. 0 means that the two strings are exactly the same, and 1 means that the two strings are completely different.

[0071] In this embodiment, by matching the description of the first measurement point with the keywords of each candidate synthetic signal template for template screening, the matching target synthetic signal template can be screened out to ensure the accuracy of synthetic signal generation.

[0072] Step 208, based on the target synthetic signal template, determine the signal synthesis method and at least one target source signal corresponding to the description of the first measurement point. Based on the signal synthesis method and at least one target source signal, generate a target synthetic signal that matches the description of the first measurement point. The target synthetic signal is used for telecontrol and detection.

[0073] Optionally, based on the word segmentation result of the target synthetic signal template, determine the signal synthesis method and the source signal name, and determine the corresponding target source signal based on the source signal name. Synthesize at least one target source signal according to the signal synthesis method to generate a target synthetic signal that matches the description of the first measurement point. The target synthetic signal is used for telecontrol and detection.

[0074] In one embodiment, as Figure 3 shown, it is a schematic flowchart of the steps for determining the signal synthesis method and the target source signal in one embodiment. Based on the target synthetic signal template, determining the signal synthesis method and at least one target source signal corresponding to the description of the first measurement point includes:

[0075] Step 302, obtain the specified signal synthesis method and at least one source signal name from the target synthetic signal template.

[0076] Optionally, the computer device determines the signal synthesis method and at least one source signal name included in the target synthetic signal template based on the word segmentation result of the target synthetic signal template.

[0077] Step 304, based on the substation configuration description file, determine the target source signal corresponding to each source signal name.

[0078] Optionally, based on the description of the second measurement point in the substation configuration description file, determine the target source signal corresponding to each source signal name.

[0079] In one embodiment, based on the substation configuration description file, determining the target source signal corresponding to each source signal name includes: screening out the target measurement point description from multiple second measurement point descriptions based on at least one source signal name and the device name in each second measurement point description; querying the target source signal corresponding to each source signal name from the substation configuration description file based on the target measurement point description.

[0080] Among them, the substation configuration description file records the source signal corresponding to each second measurement point description.

[0081] Optionally, the computer device determines a device name that matches at least one source signal, and uses the second measurement point description to which the device name belongs as the target measurement point description. Based on the target measurement point description, the computer device obtains each source signal corresponding to the target measurement point description from the substation configuration description file.

[0082] In this embodiment, through the source signal name and the device name in the second measurement point description, it can be automatically queried whether there is a target measurement point description corresponding to at least one source signal name, so that the source signal corresponding to the source signal name, that is, the target source signal, can be automatically queried. The whole process does not require manual configuration, which can avoid configuration errors and improve the synthesis efficiency.

[0083] In one embodiment, based on at least one source signal name and the device name in each second measurement point description, screening out the target measurement point description from multiple second measurement point descriptions includes: for each second measurement point description, verifying whether the device name in the second measurement point description matches at least one source signal name; in the case where it is verified that the device name in the second measurement point description matches at least one source signal name, using the second measurement point description as the target measurement point description.

[0084] Optionally, the computer device uses a third dictionary to segment the second measurement point description to obtain the device name in the second measurement point description. For each source signal name, the computer device traverses the device names of each second measurement point description to query whether there is a device name associated with the source signal name. If the device names corresponding to each source signal name are the same, the second measurement point description to which the device name belongs is used as the target measurement point description.

[0085] Among them, the construction process of the third dictionary can refer to the previous first dictionary construction process, which will not be elaborated here.

[0086] Exemplarily, the computer device determines the association relationship between the device name and the source signal name, and based on this association relationship, determines the device name corresponding to each source signal name.

[0087] In some scenarios, for the convenience of querying, when setting the device name of the second measurement point description, the associated source signal name and the name of the measurement and control device can be combined, and the combined result is used as the device name. That is to say, the device name in the second measurement point description can be segmented to obtain the third segmentation. Check whether there is a source signal name in the third segmentation. For each source signal name, check whether there is a third segmentation that is the same as the source signal name. If there is, and it is determined that the third segmentation matches the source signal, then the device name where the third segmentation is located is used as the device name corresponding to the source signal name. If not, obtain the second synonymy library between the source signal name and the device name, and query the synonyms of the source signal name in the second synonymy library. If the synonym belongs to the third segmentation, it is considered that the third segmentation matches the source signal, and the device name where the third segmentation is located is used as the device name corresponding to the source signal name. Among them, the construction process of the second synonymy library can refer to the construction process of the first synonymy library in the previous text. After determining the third segmentation that each source signal name matches, if each matching third segmentation belongs to the same second measurement point description, then the second measurement point description to which it belongs is used as the target measurement point description. The third segmentation that the source signal matches refers to that the source signal and the third segmentation are the same or synonymous.

[0088] In this embodiment, by verifying whether the device name matches the source signal name, the target measurement point description can be accurately screened out, which is convenient for accurately confirming the source signal.

[0089] In this embodiment, based on the target composite signal template, the signal synthesis method and at least one source signal name are determined. Therefore, the target source signal can be automatically determined without manual selection one by one, effectively improving the accuracy of the generated composite signal.

[0090] In the above composite signal generation method, by obtaining the detection information table of the substation and the substation configuration description file, the detection information table includes multiple first measurement point descriptions, and the substation configuration description file includes multiple second measurement point descriptions; for each first measurement point description, if it is verified that there is no second measurement point description in the substation configuration description file that matches the first measurement point description, automatically obtain multiple candidate composite signal templates; based on the first measurement point description, screen out the matching target composite signal template from the multiple candidate composite signal templates, that is, use the first measurement point description to screen the template to ensure the accuracy and effectiveness of the subsequent composite signal generation; based on the target composite signal template, determine the signal synthesis method and at least one target source signal corresponding to the first measurement point description, and adaptively generate a target composite signal that matches the first measurement point description. The target composite signal is used for remote control and detection. The whole process does not require manual configuration of the composite signal. It is automatically generated by means of the matching target composite signal template, reducing the risk of errors, thereby improving the accuracy of the generated composite signal.

[0091] In a specific embodiment, the specific steps are as follows:

[0092] Step 1: The computer device obtains a detection information table about the substation and a substation configuration description file. The detection information table includes multiple first measurement point descriptions, and the substation configuration description file includes multiple second measurement point descriptions.

[0093] Step 2: For each first measurement point description, if it is verified that there is no second measurement point description matching the first measurement point description in the substation configuration description file, obtain multiple preset composite signal templates. Each composite signal template has a corresponding priority; screen out candidate composite signal templates belonging to the preset priority from the multiple composite signal templates.

[0094] Step 3: For each candidate composite signal template, obtain the keyword of the composite signal name from the candidate composite signal template; compare each first measurement point description with the keyword of each candidate composite signal template to obtain the keyword that is consistent with the first measurement point description, and use the candidate composite signal template corresponding to the keyword that is consistent with the first measurement point description as the target composite signal template matching the first measurement point description.

[0095] Step 4: When the target composite signal template indicates that the composite signal is an interval composite signal, execute the following steps 5 - 8.
