[0029] In this embodiment, a method for automatically monitoring the status of a knife switch running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0030] Figure 2 1 is a flow chart of a method for automatically monitoring the status of a knife switch according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0031] Step S201, obtaining the analyzed switch status data of the substation, wherein the analyzed switch status data at least includes the equipment code, plant code, status quantity and analysis time;

[0032] Specifically, Figure 3 As shown, in the first safety zone, the switch status data in the substation is obtained in real time through the dispatching automation system, the switch status data at least includes the equipment code, the plant code and the status quantity, the first safety zone is the control zone in the production control area of ​​the power system; the switch status data is written into the target file, and the target file is transmitted to the second safety zone through the forward isolation device, the forward isolation device is used to limit the one-way file transmission from the first safety zone to the second safety zone, the second safety zone is the production management area in the information management area of ​​the power system; the control data synchronization service receives the target file, and parses the target file to obtain the parsed switch status data.

[0033] Step S202, analyze the data in the intermediate state in the above-mentioned analyzed knife switch status data to obtain analysis results, and automatically monitor the knife switch status according to the above-mentioned analysis results. The above-mentioned analysis operations include full-station signboard analysis, direct-connected switch signboard analysis, grounding knife switch associated main transformer signboard analysis, section knife switch analysis and direct-connected bus signboard analysis. The above-mentioned full-station signboard analysis is to mark the entire substation, the above-mentioned direct-connected switch signboard analysis is to analyze the switch directly connected to the above-mentioned knife switch, the above-mentioned grounding knife switch associated main transformer signboard analysis is to analyze the equipment connected to the grounding knife switch, the above-mentioned section knife switch analysis is to analyze the section knife switch, the above-mentioned direct-connected bus signboard analysis is to analyze the bus directly connected to the above-mentioned knife switch, and the above-mentioned intermediate state is the state of the above-mentioned knife switch state except the completely open state and the completely closed state.

[0034] Specifically, Figure 4As shown, the data in the intermediate state of the above-mentioned knife switch status data are sequentially subjected to full station sign-out analysis, direct switch sign-out analysis, grounding knife switch associated main transformer sign-out analysis, section knife switch analysis and direct bus sign-out analysis. Full station sign-out means that the entire substation has been marked and signed in a maintenance state. When the full station is signed, it may cause abnormalities in the knife switch, but it does not mean that the abnormality is caused by a fault in the knife switch itself. Therefore, in the case of full station sign-out, the abnormality of the knife switch can be ignored. Direct switch sign-out means that the switch directly connected to the knife switch has been marked and signed in a maintenance state. When the direct switch is signed, it may cause abnormalities in the knife switch, but it does not mean that the abnormality is caused by a fault in the knife switch itself. Therefore, in the case of direct switch sign-out, the abnormality of the knife switch can be ignored. The principles of other grounding knife switch associated main transformer sign-out analysis, section knife switch analysis and direct bus sign-out analysis are the same and will not be repeated here. If after the whole station signage analysis, direct-connected switch signage analysis, grounding switch associated main transformer signage analysis, section switch analysis and direct-connected bus signage analysis, it is found that none of them are marked as being under maintenance, it means that the abnormality is caused by a fault in the switch itself. At this time, it is necessary to handle the abnormality of the switch and automatically monitor the status of the abnormal switch in real time.

[0035] In this embodiment, first, the analyzed knife switch status data of the substation is obtained, and the above-mentioned analyzed knife switch status data at least includes equipment code, plant code, status quantity and analysis time; then, the data in the above-mentioned analyzed knife switch status data that is in the intermediate state is analyzed to obtain analysis results, and the knife switch status is automatically monitored according to the above-mentioned analysis results. The above-mentioned analysis operations include whole-station signboard analysis, direct-connected switch signboard analysis, grounding knife switch associated main transformer signboard analysis, section knife switch analysis and direct-connected bus signboard analysis. The above-mentioned whole-station signboard analysis is to mark the entire substation, the above-mentioned direct-connected switch signboard analysis is to analyze the switch directly connected to the above-mentioned knife switch, the above-mentioned grounding knife switch associated main transformer signboard analysis is to analyze the equipment connected to the grounding knife switch, the above-mentioned section knife switch analysis is to analyze the section knife switch, the above-mentioned direct-connected bus signboard analysis is to analyze the bus directly connected to the above-mentioned knife switch, and the above-mentioned intermediate state is the state of the above-mentioned knife switch state except the completely open state and the completely closed state. The present application obtains the analyzed switch status data, i.e., the analyzed switch status data, and analyzes the analyzed switch status data, tracks and verifies the intermediate state of the switch, and determines whether the switch is abnormal because of any of the following conditions: the whole station is listed, the direct switch is listed, the grounding switch is associated with the main transformer, the sectional switch is listed, and the direct bus is listed, or the switch itself is faulty, so as to promptly remind the dispatcher on duty to follow up. The present application solves the problem in the prior art that the intermediate state of the switch is ignored, resulting in safety risks caused by the intermediate state.

[0036] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the automatic switch status monitoring method of the present application will be described in detail below in conjunction with specific embodiments.

[0039] In the above embodiment, if Figure 3 As shown, after the data synchronization service receives the E file (target file) sent by the dispatching automation system of Zone 1, it parses the records in the E file (target file) in turn, that is, the above-mentioned parsed knife switch status data. The data synchronization service stores the above-mentioned parsed knife switch status data into the monitoring auxiliary database. Subsequently, the main station will periodically obtain data from the monitoring auxiliary database for analysis operations.

A status value of 0 indicates that the switch is closed, and a status value of 1 indicates that the switch is completely disconnected. The three-area master station begins to analyze each record in the record set T one by one. Now, take any record R in the record set T (i.e., the current record above) as an example. The current record R contains the equipment code, plant code, status value, and analysis time, etc. Figure 4As shown, the current record is sequentially subjected to the above-mentioned station-wide sign-out analysis, the above-mentioned direct-connected switch sign-out analysis, the above-mentioned grounding switch-associated main transformer sign-out analysis, the segmented switch analysis and the direct-connected bus sign-out analysis, and finally the record is marked and notified. Among them, the specific process for the segmented switch analysis is as follows: the tenth judgment step, judging whether there is a tenth target record that meets the tenth condition, the tenth condition being that the above-mentioned device number in the above-mentioned device table is the same as the above-mentioned device number of the above-mentioned current record; the eleventh judgment step, in the case where the above-mentioned tenth target record exists, judging whether the above-mentioned device name of the above-mentioned tenth target record has a second keyword, the above-mentioned second keyword is segmentation; the sixth judgment step, in the case where the above-mentioned device name of the above-mentioned tenth target record does not have the second keyword, judging that the above-mentioned segmented switch is not in the segmented switch sign-out state; the sixth update step, in the case where the above-mentioned device name of the above-mentioned tenth target record has the above-mentioned second keyword, updating the above-mentioned next record in the above-mentioned record set that has not undergone the above-mentioned segmented switch sign-out analysis to the above-mentioned current record, and re-executing the above-mentioned tenth judgment step, the above-mentioned eleventh judgment step, the above-mentioned sixth judgment step and the above-mentioned sixth update step. The analysis of direct-connected bus listing is similar. The three-zone master station obtains the record whose upper device is the device corresponding to the device code of the current record and the device type is "bus" from the device topology table, and records it as the eleventh target record. If the eleventh target record exists, the twelfth target record whose device code is the device code of the eleventh target record and the listing end time is empty is obtained from the listing information table. If the twelfth target record exists, continue to analyze the next record in the record set, otherwise execute the mark notification step; if the eleventh target record does not exist, execute the mark notification step in the same way.

If this record R3 exists, the next record in the record set T is continued to be analyzed, otherwise it is determined that the above direct-connected switch of the above knife switch is not in the above direct-connected switch hanging state, and the grounding knife switch associated main transformer hanging analysis is entered. If the third target record exists for each record in the record set T, it means that the substation is in the above direct-connected switch hanging state.

[0073] Step S202410, in the case where the sixth target record does not exist, determining whether there is a seventh target record that satisfies a seventh condition, wherein the seventh condition is that the upper-level device of the third target device in the device topology table is the device corresponding to the current record, and the device type of the third target device is the main transformer;

[0074] Step S202411, in the case where the seventh target record does not exist, determining that the device connected to the grounding switch is not in the main transformer associated with the grounding switch hanging state;

[0075] Step S202412, in the case where the seventh target record exists, determining whether there is an eighth target record that satisfies an eighth condition, wherein the eighth condition is that the device code in the switch state table is the same as the device code in the seventh target record and the state quantity is 0;

[0076] Step S202413, when the eighth target record exists, the next record in the record set that has not been subjected to the grounding switch associated main transformer sign-on analysis is updated as the current record, and the grounding switch associated main transformer sign-on analysis is performed again;

[0079] In the above embodiment, the three-zone master station obtains the record R4 corresponding to the device code of the record R from the device table, that is, the fourth target record; if the record R4 exists, it is analyzed whether the keyword "grounding switch" is in the device name of the record R4. If the keyword does not exist, it is determined that the device connected to the above grounding switch is not in the above grounding switch associated main transformer hanging state, and the segmented switch analysis is entered; otherwise, it continues to obtain the lower-level device from the device topology table as the device corresponding to the device code of the record R, and the device type is the record R5 of "main transformer (also referred to as main transformer)", that is, the fifth target record. If the record R5 does not exist, it is determined that the device connected to the above grounding switch is not in the above grounding switch associated main transformer hanging state. If the device code is the same as the device code of record R5, the analysis of the segmented knife switch is started; otherwise, the device code is obtained from the signboard information table, and the record R6 whose signboard end time is empty, that is, the sixth target record mentioned above. If this record R6 exists, the analysis of the next record in the record set T is continued. Otherwise, the upper device is obtained from the device topology table, and the device code of record R5 corresponds to the device code, and the device type is "switch" record R7, that is, the seventh target record mentioned above. Then, the device code is obtained from the knife switch status table, and the state quantity is 0 (that is, the knife switch is disconnected) record R8, that is, the eighth target record mentioned above. If this record R8 exists, the analysis of the next record in the set T is continued. Otherwise, the above-mentioned mark notification step is executed.

[0080] In order to promptly indicate the current state of the knife switch and promptly handle abnormal situations of the knife switch, in an optional implementation manner, the above step S2027 includes:

[0081] Step S20271, an eighth judgment step, judging whether there is a ninth target record satisfying a ninth condition in the set to be notified, the ninth condition being that the device code in the set to be notified is the same as the device code of the current record;

[0082] Step S20272, a fourth updating step, in which, if the ninth target record does not exist, the next record in the record set that has not been subjected to the eighth determination step is updated as the current record, and the process returns to execute the eighth determination step;

[0083] Step S20273, a ninth determination step, in the case where the ninth target record exists, marking the ninth target record, and determining whether the time interval is greater than a time threshold, the time interval being the length of time between the parsing time of the ninth target record and the parsing time of the current record;

[0084] Step S20274, a clearing step, in which, when the time interval is greater than the time threshold, a notification message is issued, and the ninth target record is cleared from the set to be notified;

[0085] Step S20275, the fifth update step, when the above time interval is less than or equal to the above time threshold, the next record in the above record set that has not been analyzed in the above eighth judgment step is updated to the above current record, and the above eighth judgment step, the above fourth update step, the above ninth judgment step, the above clearing step and the above fifth update step are repeated in sequence until all the above records in the above record set have completed the analysis.

[0086] In the above embodiment, the three-zone master station determines whether there is a record R9 in the set to be notified T2 whose equipment code is consistent with the equipment code in the record R, that is, the ninth target record, and then marks the record R9, and then determines whether the parsing time of the record R9 is more than 10 minutes apart from the parsing time of the record R (that is, the above time threshold, the specific time is set according to the actual situation). If it is more than 10 minutes, the record R10 with the department "dispatching" and the position "duty officer" is obtained from the personnel telephone table of the monitoring auxiliary database, and then the record with the equipment code of the record R is obtained from the equipment table of the monitoring auxiliary database, and the equipment code of the record R is obtained. The device name of the equipment is obtained, and then the record with the plant station code in the record R is obtained from the plant station table to obtain the plant station name of the equipment, and then a notification message "XX station XX equipment dispatching automation system shows intermediate state, please verify" is generated. The three-area master station sends the notification message and all the contact phone numbers in record R10 to the SMS platform and the telephone platform. After receiving the phone number and notification content, the SMS platform and the telephone platform send SMS messages with the notification content to these phone numbers in turn and make telephone notifications, and remove record R9 from the set to be notified T2; if it does not exceed 10 minutes, continue to analyze the next record in the set T. If there is no record in the set to be notified T2 with the same device code as the device code in record R, then add record R to the set to be notified T2 and mark it. After all records in the record set T are analyzed, all unmarked records in the set to be notified T2 are cleared, and after clearing, all marked records are cleared of their marking status (that is, changed to unmarked status), but they still exist in the set to be notified T2.

[0087] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0088] The embodiment of the present application also provides a device for automatically monitoring the status of a knife switch. It should be noted that the device for automatically monitoring the status of a knife switch in the embodiment of the present application can be used to execute the method for automatically monitoring the status of a knife switch provided in the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

[0089] The following is an introduction to the automatic monitoring device for knife switch status provided in an embodiment of the present application.

[0090] Figure 5 is a structural block diagram of a device for automatically monitoring the status of a knife switch according to an embodiment of the present application. Figure 5 As shown, the device comprises:

[0091] The acquisition unit 10 is used to acquire the analyzed switch status data of the substation, wherein the analyzed switch status data at least includes the equipment code, the plant code, the status quantity and the analysis time;

[0092] Specifically, Figure 3 As shown, in the first safety zone, the switch status data in the substation is obtained in real time through the dispatching automation system, the switch status data at least includes the equipment code, the plant code and the status quantity, the first safety zone is the control zone in the production control area of ​​the power system; the switch status data is written into the target file, and the target file is transmitted to the second safety zone through the forward isolation device, the forward isolation device is used to limit the one-way file transmission from the first safety zone to the second safety zone, the second safety zone is the production management area in the information management area of ​​the power system; the control data synchronization service receives the target file, and parses the target file to obtain the parsed switch status data.

[0093] The analysis unit 20 is used to perform analysis operations on the data in the intermediate state in the above-mentioned analyzed knife switch status data to obtain analysis results, and automatically monitor the knife switch status according to the above-mentioned analysis results. The above-mentioned analysis operations include full-station signboard analysis, direct-connected switch signboard analysis, grounding knife switch associated main transformer signboard analysis, section knife switch analysis and direct-connected bus signboard analysis. The above-mentioned full-station signboard analysis is to mark the entire substation, the above-mentioned direct-connected switch signboard analysis is to analyze the switch directly connected to the above-mentioned knife switch, the above-mentioned grounding knife switch associated main transformer signboard analysis is to analyze the equipment connected to the grounding knife switch, the above-mentioned section knife switch analysis is to analyze the section knife switch, the above-mentioned direct-connected bus signboard analysis is to analyze the bus directly connected to the above-mentioned knife switch, and the above-mentioned intermediate state is the state of the above-mentioned knife switch state except the fully open state and the fully closed state.

[0094] Specifically, Figure 4 As shown, the data in the intermediate state of the above-mentioned knife switch status data are sequentially subjected to full station sign-out analysis, direct switch sign-out analysis, grounding knife switch associated main transformer sign-out analysis, section knife switch analysis and direct bus sign-out analysis. Full station sign-out means that the entire substation has been marked and signed in a maintenance state. When the full station is signed, it may cause abnormalities in the knife switch, but it does not mean that the abnormality is caused by a fault in the knife switch itself. Therefore, in the case of full station sign-out, the abnormality of the knife switch can be ignored. Direct switch sign-out means that the switch directly connected to the knife switch has been marked and signed in a maintenance state. When the direct switch is signed, it may cause abnormalities in the knife switch, but it does not mean that the abnormality is caused by a fault in the knife switch itself. Therefore, in the case of direct switch sign-out, the abnormality of the knife switch can be ignored. The principles of other grounding knife switch associated main transformer sign-out analysis, section knife switch analysis and direct bus sign-out analysis are the same and will not be repeated here. If after the whole station signage analysis, direct-connected switch signage analysis, grounding switch associated main transformer signage analysis, section switch analysis and direct-connected bus signage analysis, it is found that none of them are marked as being under maintenance, it means that the abnormality is caused by a fault in the switch itself. At this time, it is necessary to handle the abnormality of the switch and automatically monitor the status of the abnormal switch in real time.

[0095] In this embodiment, an acquisition unit is used to acquire parsed knife switch status data of the substation, and the parsed knife switch status data at least includes equipment code, plant code, status quantity and parsing time; an analysis unit is used to perform analysis operations on the data in the intermediate state in the parsed knife switch status data to obtain analysis results, and automatically monitor the knife switch status according to the analysis results, and the analysis operations include full-station sign-up analysis, direct-connected switch sign-up analysis, grounding knife switch associated main transformer sign-up analysis, sectioned knife switch analysis and direct-connected bus sign-up analysis. The full-station sign-up analysis is to perform a marking analysis on the entire substation, the direct-connected switch sign-up analysis is to analyze the switch directly connected to the knife switch, the grounding knife switch associated main transformer sign-up analysis is to analyze the equipment connected to the grounding knife switch, the sectioned knife switch analysis is to analyze the sectioned knife switch, and the direct-connected bus sign-up analysis is to analyze the bus directly connected to the knife switch. The intermediate state is the state of the knife switch except for the completely open state and the completely closed state. The present application obtains the analyzed switch status data, i.e. analyzes the analyzed switch status data, tracks and verifies the intermediate state of the switch, and determines whether the switch is abnormal due to any of the following conditions: the whole station is listed, the direct switch is listed, the grounding switch is associated with the main transformer, the sectional switch is listed, and the direct busbar is listed, or the switch itself is faulty, so as to promptly remind the dispatcher on duty to follow up. The present application solves the problem in the prior art that the intermediate state of the switch is ignored, resulting in safety risks caused by the intermediate state.

[0096] In order to improve the security of the switch status data and facilitate data management, in an optional implementation manner, the device further includes:

[0097] A storage unit is used to obtain the parsed knife switch status data of the substation, and then store the parsed knife switch status data in a monitoring auxiliary database. The monitoring auxiliary database at least stores a knife switch status table, an equipment table, a plant station table, a listing information table, an equipment topology table and a personnel telephone table. The knife switch status table includes the equipment code, the plant station code, the status quantity and the parsing time. The equipment table includes the equipment code, the equipment name, the plant station code and the equipment type. The plant station table includes the plant station code and the plant station name. The listing information table includes the equipment code, the plant station code, the listing start time, the listing end time and the listing information. The equipment topology table includes the equipment code, the equipment type and the upper and lower equipment of the equipment corresponding to the equipment code. The personnel telephone table includes the identity information and contact information of the operator.

[0098] In the above embodiment, if Figure 3As shown, after the data synchronization service receives the E file (target file) sent by the dispatching automation system of Zone 1, it parses the records in the E file (target file) in turn, that is, the above-mentioned parsed knife switch status data. The data synchronization service stores the above-mentioned parsed knife switch status data into the monitoring auxiliary database. Subsequently, the main station will periodically obtain data from the monitoring auxiliary database for analysis operations. The above-mentioned E file is a file for storing the status data of the knife switch in the dispatching automation system acquisition station.

[0099] In order to accurately detect the state of the knife switch, in an optional implementation manner, the above-mentioned analysis unit includes:

[0100] A reading module reads all intermediate state data sets to obtain a record set, wherein the record set includes a set formed by multiple records, and any one of the records includes the equipment code, the plant station code, the state quantity and the listing information table;

[0103] A third analysis module is used to execute a third analysis step, and when it is determined in the above-mentioned direct-connection switch hanging analysis that the direct-connection switch of the above-mentioned knife switch is not in the direct-connection switch hanging state, a hanging analysis of the main transformer associated with the above-mentioned grounding knife switch is performed, and the above-mentioned direct-connection switch hanging state is that the above-mentioned direct-connection switch of the above-mentioned knife switch is in a maintenance state;

[0104] A fourth analysis module is used to execute a fourth analysis step, and when it is determined in the above-mentioned grounding switch associated main transformer hanging sign analysis that the device connected to the above-mentioned grounding switch is not in the grounding switch associated main transformer hanging sign state, perform the above-mentioned sectional switch analysis;

[0105] A fifth analysis module, used to execute the fifth analysis step, and to perform the above-mentioned direct-connected bus hanging analysis when it is determined in the above-mentioned sectionalized knife switch analysis that the above-mentioned sectionalized knife switch does not exist;

[0106] a marking notification module, used for executing the marking notification step, and marking the records in the to-be-notified set according to the current record and issuing a notification message when it is determined in the above-mentioned direct-connected bus hanging analysis that the above-mentioned knife switch does not have a direct-connected bus and is in a direct-connected bus hanging state, wherein the above-mentioned notification message is used for notifying that the above-mentioned knife switch state has an abnormal situation, and the above-mentioned to-be-notified set is a set of the above-mentioned records for which the above-mentioned notification message is to be issued;

[0107] The repeating module repeats the first analysis step, the second analysis step, the third analysis step, the fourth analysis step, the fifth analysis step and the marking notification step at least once in sequence until all the records in the record set are analyzed to obtain the analysis results.

[0108] In the above embodiment, the three-area master station periodically reads the switch status table data from the monitoring auxiliary database, obtains all records whose status values ​​are not 0 and 1, and obtains a record set T. A status value of 0 indicates that the switch is closed, and a status value of 1 indicates that the switch is completely disconnected. The three-area master station begins to analyze each record in the record set T one by one. Now, take any record R in the record set T (i.e., the current record above) as an example. The current record R contains the equipment code, plant code, status value, and analysis time, etc. Figure 4As shown, the current record is sequentially subjected to the above-mentioned station-wide sign-out analysis, the above-mentioned direct-connected switch sign-out analysis, the above-mentioned grounding switch-associated main transformer sign-out analysis, the segmented switch analysis and the direct-connected busbar sign-out analysis, and finally the record is marked and notified. Among them, the specific process for the segmented switch analysis is as follows: the tenth judgment step, judging whether there is a tenth target record that meets the tenth condition, the tenth condition being that the above-mentioned device number in the above-mentioned device table is the same as the above-mentioned device number of the above-mentioned current record; the eleventh judgment step, in the case where the above-mentioned tenth target record exists, judging whether the above-mentioned device name of the above-mentioned tenth target record has a second keyword, the above-mentioned second keyword is segmentation; the sixth judgment step, in the case where the above-mentioned device name of the above-mentioned tenth target record does not have the second keyword, judging that the above-mentioned segmented switch is not in the segmented switch sign-out state; the sixth update step, in the case where the above-mentioned device name of the above-mentioned tenth target record has the above-mentioned second keyword, updating the above-mentioned next record in the above-mentioned record set that has not undergone the above-mentioned segmented switch analysis to the above-mentioned current record, and re-executing the above-mentioned tenth judgment step, the above-mentioned eleventh judgment step, the above-mentioned sixth judgment step and the above-mentioned sixth update step. The analysis of direct-connected bus listing is similar. The three-zone master station obtains the record whose upper device is the device corresponding to the device code of the current record and the device type is "bus" from the device topology table, and records it as the eleventh target record. If the eleventh target record exists, the twelfth target record whose device code is the device code of the eleventh target record and the listing end time is empty is obtained from the listing information table. If the twelfth target record exists, continue to analyze the next record in the record set, otherwise execute the mark notification step; if the eleventh target record does not exist, execute the mark notification step in the same way.

[0109] In order to perform the whole station signboard analysis to improve the accuracy of judging the switch status, in an optional implementation, the first analysis module includes:

[0110] A first judgment submodule is used to execute a first judgment step to judge whether there is a first target record that meets a first condition, wherein the first condition is that the plant station code in the listing information table is the same as the plant station code of the current record, the listing information is a full station sign, and the listing end time is empty;

[0111] A first determination submodule is used to execute a first determination step, and determine that the substation is not in the full station listing state when there is no first target record corresponding to the current record;

[0112] A first updating submodule is used to execute a first updating step, in the case where there is the first target record corresponding to the current record, update the next record in the record set that has not been subjected to the full-station listing analysis to the current record, and re-execute the first judging step, the first determining step and the first updating step;

[0113] The second determination submodule determines that the substation is in the full-station listing state when the first target record exists in all records in the record set.

[0114] In the above embodiment, the record whose plant station code is the same as the plant station code of the current record R, whose sign-off information is "full station sign-off", and whose sign-off end time is empty is obtained from the sign-off information table, that is, the above-mentioned first target record. If the first target record exists, the next record in the record set T is analyzed continuously, otherwise it is determined that the above-mentioned substation is not in the above-mentioned full station sign-off state, and the direct-connected switch sign-off analysis is entered. If the first target record exists in each record in the record set T, it means that the substation is in the above-mentioned full station sign-off state.

[0115] In order to perform direct switch hanging analysis to improve the accuracy of judging the switch status, in an optional implementation, the second analysis module includes:

[0116] A second judgment submodule is used to perform a second judgment step to judge whether there is a second target record that meets a second condition, wherein the second condition is that the subordinate device of the first target device in the device topology table is the device corresponding to the current record, and the device type of the first target device is a switch;
