Description

Technical Field

[0001] The present application relates to the technical field of distribution line fault location, and in particular to a method and device for detecting abnormal internal communication of a fault indicator, a storage medium, and a computer device. Background Art

[0002] In a 10kV distribution network, especially one that utilizes numerous circuit breakers, if a short circuit or ground fault occurs in a lower-level distribution line, the upper-level circuit breaker must trip within a specified timeframe to prevent a major accident. Fault indicators on distribution lines can be used to indicate short circuit and ground fault conditions. By using these indicators, faulty sections of the distribution line can be pinpointed. Based on the alarm signals from the fault indicators, maintenance personnel can quickly locate the faulty section and disconnect it, promptly restoring power to the undamaged sections. This can save significant time and reduce the duration and scope of power outages.

[0003] It can be seen that whether the communication of the fault indicator is normal directly affects the analysis results of the fault section. The current method used by the operation and maintenance personnel on the master station side to determine whether the communication of the fault indicator is normal is to check whether the fault indicator is online. However, the fault indicator includes an acquisition unit and an aggregation unit, and its communication can be divided into two parts, one part is from the acquisition unit to the aggregation unit, and the other part is from the aggregation unit to the master station. When the communication between the acquisition unit and the aggregation unit is abnormal, the telemetry message and telesignaling message of the acquisition unit cannot be uploaded to the aggregation unit. Then, when the distribution line corresponding to the fault indicator fails, although the fault indicator is online, the master station side cannot receive the telemetry message and telesignaling message, resulting in the inability of the operation and maintenance personnel to correctly judge the fault section after the fault, thereby greatly reducing the emergency repair efficiency and prolonging the emergency repair time for restoring power supply. Therefore, how to determine whether the internal communication of the fault indicator is abnormal has become a technical problem that needs to be solved urgently in this field. Summary of the Invention

[0004] In view of this, the present application provides a method and device, storage medium, and computer equipment for detecting abnormal internal communication of a fault indicator. Without increasing hardware costs, the judgment of whether the internal communication of the fault indicator is abnormal can be achieved through the original control end on the master station side. It is simple and convenient, and can greatly improve the stability and reliability of the fault indicator.

[0005] According to one aspect of the present application, a method for detecting abnormal internal communication of a fault indicator is provided, comprising:

[0006] Receive messages sent by a collection unit in any fault indicator, and identify telesignaling messages and telemetering messages from the messages;

[0007] Performing message analysis on the telesignaling message and the telemetry message respectively, and updating the internal communication abnormality level and flag bit corresponding to any fault indicator based on the analysis results;

[0008] When the updated internal communication abnormality level reaches a preset level threshold, it is determined whether the flag bit corresponding to any fault indicator is a specified value, and when it is not the specified value, it is determined that the internal communication of any fault indicator is abnormal.

[0009] According to another aspect of the present application, a device for detecting abnormal internal communication of a fault indicator is provided, comprising:

[0010] A message receiving module, configured to receive messages sent by a collection unit in any fault indicator and identify telesignaling messages and telemetry messages from the messages;

[0011] A message analysis module, configured to perform message analysis on the telesignaling message and the telemetry message respectively, and update the internal communication abnormality level and flag bit corresponding to any fault indicator based on the analysis results;

[0012] The abnormality determination module is used to determine whether the flag bit corresponding to any fault indicator is a specified value when the updated internal communication abnormality level reaches a preset level threshold, and when it is not the specified value, determine that the internal communication of any fault indicator is abnormal.

[0013] According to another aspect of the present application, a storage medium is provided, on which a computer program is stored. When the program is executed by a processor, the method for detecting abnormal communication within the fault indicator is implemented.

[0014] According to another aspect of the present application, a computer device is provided, including a storage medium, a processor, and a computer program stored on the storage medium and executable on the processor, wherein the processor implements the above-mentioned method for detecting abnormal internal communication of the fault indicator when executing the program.

[0015] By utilizing the above technical solution, the present application provides a method and apparatus, storage medium, and computer device for detecting internal communication anomalies in a fault indicator. First, messages sent by a collection unit in any fault indicator can be received and distinguished between telesignaling messages and telemetry messages. Next, the received telesignaling and telemetry messages can be analyzed separately. The internal communication anomaly level and flag corresponding to the fault indicator can be updated based on the analysis results of the telesignaling messages. The internal communication anomaly level and flag corresponding to the fault indicator can also be updated based on the analysis results of the telemetry messages. Each time the internal communication anomaly level is updated, the updated internal communication anomaly level can be compared with a preset level threshold. If the comparison shows that the internal communication anomaly level is greater than or equal to the preset level threshold, it can be further determined whether the flag corresponding to the fault indicator is a specified value. If not, it can be determined that an internal communication anomaly exists in the fault indicator. This embodiment of the present application eliminates the need for additional hardware costs and can be implemented using the existing control terminal on the master station side. This is simple and convenient, and can significantly improve the stability and reliability of the fault indicator.

[0023] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0024] In this embodiment, a method for detecting abnormal communication within a fault indicator is provided, such as Figure 1 As shown, the method includes:

[0025] Step 101, receiving a message sent by a collection unit in any fault indicator, and identifying a telesignaling message and a telemetering message from the message;

[0026] Each fault indicator may include a three-phase acquisition unit and a collection unit, such as Figure 2 As shown, micro-power wireless communication can be achieved between the three-phase acquisition unit and the collection unit, and wireless or optical fiber communication can be achieved between the collection unit and the distribution automation master station. The method for detecting abnormal internal communication of the fault indicator provided in the embodiment of the present application can be specifically applied to the control end on the master station side, and can be used to detect whether the communication between the internal acquisition unit (three-phase acquisition unit) and the collection unit of the fault indicator is abnormal. If the communication between the acquisition unit and the collection unit is abnormal, the remote signaling message and telemetry message sent by the acquisition unit will not be sent to the control end on the master station side through the collection unit, or there will be a situation where the remote signaling message or telemetry message is missing, so that the control end cannot determine the fault section in the distribution line. In the method for detecting abnormal internal communication of the fault indicator in the embodiment of the present application, all fault indicators that have been modeled on the master station side can be detected in real time. First, the message sent by the collection unit in any fault indicator can be received, wherein the message can include a heartbeat message, a remote signaling message, a telemetry message, etc. Then, the remote signaling message and the telemetry message can be identified therefrom.

[0027] Step 102: Analyze the telesignaling message and the telemetry message respectively, and update the internal communication abnormality level and flag corresponding to any fault indicator based on the analysis results;

[0028] In this embodiment, received telesignaling messages and telemetry messages can be analyzed separately. Subsequently, the internal communication anomaly level and flag corresponding to the fault indicator can be updated based on the analysis results of the telesignaling message, and the internal communication anomaly level and flag corresponding to the fault indicator can also be updated based on the analysis results of the telemetry message. The internal communication anomaly level and flag are global variables. For example, if the internal communication anomaly level has just been updated based on the analysis results of the telesignaling message and the updated result is obtained, and the analysis results of the telemetry message also meet the internal communication anomaly level update conditions, then a further update can be performed based on the updated result.

[0029] Step 103 : When the updated internal communication abnormality level reaches a preset level threshold, it is determined whether the flag bit corresponding to any fault indicator is a specified value, and if it is not the specified value, it is determined that the internal communication of any fault indicator is abnormal.

[0030] In this embodiment, each time the internal communication anomaly level is updated, the updated internal communication anomaly level can be compared with a preset level threshold. If the comparison finds that the internal communication anomaly level is greater than or equal to the preset level threshold, a further determination can be made as to whether the flag bit corresponding to the fault indicator is a specified value. If not, it can be determined that an internal communication anomaly exists in the fault indicator.

[0031] By applying the technical solution of this embodiment, first, messages sent by the aggregation unit in any fault indicator can be received and distinguished between telesignaling messages and telemetry messages. Next, the received telesignaling messages and telemetry messages can be analyzed separately. The internal communication anomaly level and flag bit corresponding to the fault indicator can then be updated based on the analysis results of the telesignaling messages. Alternatively, the internal communication anomaly level and flag bit corresponding to the fault indicator can be updated based on the analysis results of the telemetry messages. Each time the internal communication anomaly level is updated, the updated internal communication anomaly level can be compared with a preset level threshold. If the comparison finds that the internal communication anomaly level is greater than or equal to the preset level threshold, it can be further determined whether the flag bit corresponding to the fault indicator is a specified value. If it is not, it can be determined that there is an anomaly in the internal communication of the fault indicator. This embodiment of the application does not require additional hardware costs; the determination of whether the internal communication of the fault indicator is abnormal can be achieved through the existing control terminal on the master station side. This is simple and convenient, and can significantly improve the stability and reliability of the fault indicator.

[0032] Furthermore, as a refinement and expansion of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, another method for detecting abnormal internal communication of a fault indicator is provided, such as Figure 3As shown, the method includes:

[0033] Step 201: receiving a message sent by a collection unit in any fault indicator, and identifying a telesignaling message and a telemetering message from the message;

[0034] In this embodiment, first, a message sent by a collection unit in any fault indicator can be received, and a telesignaling message and a telemetering message can be identified therefrom.

[0035] Step 202: Analyze the telesignaling message and the telemetry message respectively, and update the internal communication abnormality level and flag bit corresponding to any fault indicator based on the analysis results;

[0036] In this embodiment, the received telesignaling message and telemetry message can then be analyzed separately. The internal communication abnormality level and flag bit corresponding to the fault indicator can then be updated based on the analysis results of the telesignaling message, and the internal communication abnormality level and flag bit corresponding to the fault indicator can also be updated based on the analysis results of the telemetry message.

[0037] Step 203: When the updated internal communication abnormality level reaches a preset level threshold, output the ledger information of any fault indicator;

[0038] In this embodiment, each time the internal communication anomaly level is updated, the updated internal communication anomaly level can be compared with a preset level threshold. If the comparison finds that the internal communication anomaly level is greater than or equal to the preset level threshold, the corresponding ledger information of the fault indicator can be output. The ledger information may include relevant information such as the fault indicator's ID, manufacturer, model, and installation location. This allows operation and maintenance personnel to quickly locate the corresponding fault indicator based on the received ledger information.

[0039] Step 204, determine whether the flag bit corresponding to any of the fault indicators is a specified value, and when it is not the specified value, determine that the internal communication of any of the fault indicators is abnormal; when it is the specified value, determine whether any of the fault indicators is mounted on an unloaded line, and when it is not mounted on an unloaded line, determine that the internal communication of any of the fault indicators is abnormal.

[0040] In this embodiment, it is further possible to determine whether the flag bit corresponding to the fault indicator is a specified value. If it is not a specified value, it can be determined that there is an abnormality in the internal communication of the fault indicator. If it is a specified value, it can be determined whether the fault indicator is mounted on an unloaded line. If the fault indicator is not mounted on an unloaded line, it can also be determined that there is an abnormality in the internal communication of the fault indicator. Regardless of whether it is determined that there is an abnormality in the internal communication of the fault indicator or that the fault indicator is mounted on an unloaded line, the operation and maintenance personnel can quickly locate the corresponding fault indicator based on the fault indicator ledger information output in step 203, and obtain relevant information such as the manufacturer of the fault indicator. By setting a global variable such as a flag bit, the embodiment of the present application can avoid the need to determine which fault indicators are mounted on the no-load line before the fault indicator is used. Subsequently, when the updated internal communication anomaly level reaches the preset level threshold, the real cause of the updated internal communication anomaly level reaching the preset level threshold is determined based on the flag bit corresponding to the fault indicator, which is more convenient. In addition, by outputting the ledger information of the fault indicator when the updated internal communication anomaly level reaches the preset level threshold, the embodiment of the present application facilitates the operation and maintenance personnel to quickly locate the fault indicator with problems, thereby reducing troubleshooting time and improving troubleshooting efficiency.

[0041] In an embodiment of the present application, optionally, the "performing message analysis on the telesignaling message and updating the internal communication abnormality level corresponding to any fault indicator based on the analysis result" in step 202 includes: based on a first preset number of continuous telesignaling messages, determining a message combination corresponding to the continuous telesignaling message, the message combination consisting of fault telesignaling and / or reset telesignaling; based on the message combination, determining whether the message combination consists of the fault telesignaling and the reset telesignaling alternatingly; when the result is no, updating the internal communication abnormality level corresponding to any fault indicator once; when the result is yes, restoring the internal communication abnormality level corresponding to any fault indicator to the first initial value.

[0042] In this embodiment, if communication between the acquisition unit and the aggregation unit is normal, the telesignaling message received by the master station control terminal should be a repetition of a fault telesignaling message and a reset telesignaling message. Therefore, to determine whether communication between the acquisition unit and the aggregation unit is normal based on the telesignaling message, the message combinations contained in the first preset number of consecutive telesignaling messages can be determined, that is, the arrangement of the fault telesignaling messages and the reset telesignaling messages in the consecutive telesignaling messages. Under normal circumstances, the arrangement should be: fault telesignaling + reset telesignaling + fault telesignaling + reset telesignaling... If the message combination in the continuous telesignaling message is not in the above form, it means that the telesignaling message is lost. At this time, the internal communication abnormality level corresponding to the fault indicator that sends the telesignaling message can be updated. Specifically, it can be updated by adding 1 to the original internal communication abnormality level, that is, upgrading it by one level; if the message combination in the continuous telesignaling message is in the above form, it means that the communication between the acquisition unit and the aggregation unit is normal. At this time, the internal communication abnormality level corresponding to the fault indicator that sends the telesignaling message can be restored to the first initial value. The first initial value is the initial value of the internal communication abnormality level. For example, if the first preset number is 4, the message combination can be determined from the 4 consecutive telesignal messages received. If the message combination is "fault telesignal + reset telesignal + fault telesignal + reset telesignal", or "reset telesignal + fault telesignal + reset telesignal + fault telesignal", then the communication between the acquisition unit and the aggregation unit in the fault indicator is normal; if it is "fault telesignal + reset telesignal + fault telesignal + fault telesignal", or "reset telesignal + fault telesignal + reset telesignal + reset telesignal", etc., then it means that there is a missing telesignal message, that is, the communication between the acquisition unit and the aggregation unit in the fault indicator is abnormal.

[0043] In the embodiment of the present application, optionally, after “updating the internal communication abnormality level corresponding to any one of the fault indicators once”, the method further includes: when the updated internal communication abnormality level does not reach the preset level threshold, updating the first preset number of continuous telesignaling messages according to a first preset rule, and returning to the step of determining the message combination corresponding to the continuous telesignaling messages;

[0044] After "restoring the internal communication abnormality level corresponding to any fault indicator to the first initial value", the method also includes: when the updated internal communication abnormality level does not reach the preset level threshold, according to the second preset rule, updating the first preset number of continuous telesignaling messages, and returning to the step of determining the message combination corresponding to the continuous telesignaling messages.

[0045] In this embodiment, after the internal communication anomaly level corresponding to the fault indicator is updated, if the updated internal communication anomaly level does not reach the preset level threshold compared to the preset level threshold, then the first preset number of consecutive telesignaling messages may be updated according to a first preset rule. Specifically, the first preset rule may be: the telesignaling message with the earliest reception time among the first preset number of consecutive telesignaling messages is updated with the newly received telesignaling message. For example, if the first preset number is 4, and the corresponding consecutive telesignaling messages are telesignaling message 1, telesignaling message 2, telesignaling message 3, and telesignaling message 4, respectively, where telesignaling message 1 is received the earliest and telesignaling message 4 is received the latest, then when updating the first preset number of consecutive telesignaling messages, the newly received telesignaling message 5 may be added and telesignaling message 1 may be removed. In this way, the updated consecutive telesignaling messages are telesignaling message 2, telesignaling message 3, telesignaling message 4, and telesignaling message 5, respectively. After updating the first preset number of continuous telesignaling messages, the process returns to the step of determining the message combination corresponding to the continuous telesignaling messages, and ends when the updated internal communication abnormality level reaches the preset level threshold.

[0046] In addition, after restoring the internal communication anomaly level corresponding to the fault indicator to the first initial value, if the updated internal communication anomaly level does not reach the preset level threshold compared to the preset level threshold, then the first preset number of continuous telesignaling messages can be updated according to the second preset rule. Specifically, the second preset rule can be: all of the previous first preset number of continuous telesignaling messages are deleted, and a new first preset number of continuous telesignaling messages are obtained. For example, if the first preset number is 4, and the corresponding continuous telesignaling messages are telesignaling message 1, telesignaling message 2, telesignaling message 3, and telesignaling message 4, then when updating the first preset number of continuous telesignaling messages, telesignaling messages 1 to 4 can be deleted, and the newly received telesignaling messages 5 to 8 can be used to update the previous continuous telesignaling messages. After updating the first preset number of continuous telesignaling messages, the process can return to the step of determining the message combination corresponding to the continuous telesignaling messages, and the process ends when the updated internal communication anomaly level reaches the preset level threshold.

[0047] The embodiment of the present application updates a first preset number of continuous telesignaling messages through the first preset rule and the second preset rule, which can reduce the storage of obsolete data and reduce resource usage.

[0048] In an embodiment of the present application, optionally, the "performing message analysis on the telemetry message, and updating the internal communication abnormality level and flag bit corresponding to any fault indicator based on the analysis result" in step 202 includes: determining the matching degree between the continuous telemetry message and the preset condition based on a second preset number of continuous telemetry messages, and the telemetry message includes a three-phase current value; when a third preset number of telemetry messages exist in the continuous telemetry message that meet the first preset condition, updating the internal communication abnormality level corresponding to any fault indicator, and the first preset condition is that one phase current value or two phase current values ​​in the three-phase current value are zero , the remaining phase current value is higher than the preset current threshold; when there are a fourth preset number of telemetry messages in the continuous telemetry messages that meet the second preset condition, the flag bit corresponding to any fault indicator is updated to a specified value, and the internal communication abnormality level corresponding to any fault indicator is updated once, and the second preset condition is that the three-phase current values ​​are all zero; when there are at least a fifth preset number of telemetry messages in the continuous telemetry messages that meet the second preset condition, and there are telemetry messages that do not meet the second preset condition, the flag bit is restored to the second initial value and locked, and the internal communication abnormality level corresponding to any fault indicator is updated once.

[0049] In this embodiment, in order to determine whether the communication between the collection unit and the aggregation unit is normal from the perspective of telemetry messages, the matching degree between the continuous telemetry messages and the preset conditions can be determined based on a second preset number of continuous telemetry messages, and the matching degree can be used to determine whether the internal communication abnormality level and flag of the fault indicator are updated. The telemetry message can include three-phase current values, and the aforementioned preset conditions can include a first preset condition and a second preset condition. The first preset condition is that among the three-phase current values, one phase current value or two phase current values ​​are zero, and the remaining phase current values ​​are higher than the preset current threshold; the second preset condition is that all three phase current values ​​are zero. When the first preset condition is met, it indicates that some phase telemetry messages in the group of three-phase telemetry messages are lost, and therefore there is an internal communication abnormality; when the second preset condition is met, it indicates that the group of three-phase telemetry messages may be abnormal, there is telemetry message loss, or the fault indicator may be mounted on an unloaded line.

[0050] If a third preset number of telemetry messages out of a second preset number of consecutive telemetry messages meet the first preset condition, the internal communication anomaly level corresponding to the fault indicator can be updated. For example, if the second preset number is 5 and the third preset number is 3, and if three out of five consecutive telemetry messages meet the first preset condition, the internal communication anomaly level corresponding to the fault indicator can be upgraded by one level. The preset current threshold in the first preset condition can specifically be 10A.

[0051] If a fourth predetermined number of telemetry messages within the second predetermined number of consecutive telemetry messages satisfy the second predetermined condition, the flag bit corresponding to the fault indicator may be updated to a specified value, and the internal communication anomaly level corresponding to the fault indicator may be simultaneously updated. For example, if the second predetermined number is 5, the fourth predetermined number is 5, and the specified value of the flag bit is 1, then if all five consecutive telemetry messages satisfy the second predetermined condition, the flag bit corresponding to the fault indicator may be updated to 1, and the internal communication anomaly level corresponding to the fault indicator may be increased by one level.

[0052] If, among the second preset number of continuous telemetry messages, at least the fifth preset number of telemetry messages satisfy the second preset condition, and there are also telemetry messages that do not satisfy the second preset condition, then the flag bit corresponding to the fault indicator can be restored to the second initial value, and it can also be locked after being restored to the second initial value so that it will not change subsequently. At the same time, the internal communication abnormality level corresponding to the fault indicator can also be updated. Here, the second initial value is the initial value corresponding to the flag bit. For example, the second preset number is 5, the fifth preset number is 3, and the second initial value is 0. Then, if at least 3 groups of telemetry messages among 5 groups of continuous telemetry messages satisfy the second preset condition, and at least 1 group of telemetry messages does not satisfy the second preset condition, then the internal communication abnormality level corresponding to the fault indicator can be raised by one level, and at the same time, the flag bit can be restored to 0 and locked.

[0053] Before the fault indicator is put into use, the internal communication abnormality level may be set to a first initial value, and the flag position may be set to a second initial value.

[0054] In an embodiment of the present application, after the "updating the internal communication abnormality level corresponding to any of the fault indicators once", the method also includes: when the updated internal communication abnormality level does not reach the preset level threshold, according to the third preset rule, updating the second preset number of continuous telemetry messages, and returning to the step of determining the matching degree of the continuous telemetry message with the preset condition.

[0055] In this embodiment, regardless of which preset condition the second preset number of continuous telemetry messages meets, once the internal communication anomaly level is updated, the magnitude relationship between the updated internal communication anomaly level and the preset level threshold can be determined. If, upon determination, it is determined that the updated internal communication anomaly level is less than the preset level threshold, the second preset number of continuous telemetry messages can be updated according to a third preset rule. Specifically, the third preset rule can be: all previous second preset number of continuous telemetry messages are deleted, and a new second preset number of continuous telemetry messages are obtained. For example, if the second preset number is 5, and the corresponding continuous telemetry messages are telemetry message 1, telemetry message 2, telemetry message 3, telemetry message 4, and telemetry message 5, respectively, then when updating the second preset number of continuous telemetry messages, telemetry messages 1 through 5 can be deleted, and the newly received telemetry messages 6 through 10 can be used to update the previous continuous telemetry messages. After updating the second preset number of continuous telemetry messages, the process returns to the step of determining the degree of matching between the continuous telemetry messages and the preset conditions, and continues until the updated internal communication anomaly level reaches the preset level threshold. In this embodiment of the present application, by updating the second preset number of continuous telemetry messages using a third preset rule, the storage of obsolete data can be reduced, thereby reducing resource usage.

[0056] In an embodiment of the present application, optionally, the method further includes: when there is a sixth preset number of telemetry messages in the continuous telemetry messages that meet the third preset condition, outputting a telemetry data abnormality alarm, updating the second preset number of continuous telemetry messages, and returning to the step of determining the matching degree of the continuous telemetry message with the preset condition, the third preset condition being the maximum value among the three-phase current values, which is greater than a preset multiple of the minimum value among the three-phase current values, and does not meet the first preset condition.

[0057] In this embodiment, the preset conditions may further include a third preset condition. The third preset condition is that the maximum value of the three-phase current values ​​must be greater than the preset multiple of the minimum value of the three-phase current values, and at the same time, the first preset condition cannot be met. For example, if the preset multiple is 10, then the third preset condition is max{I a ,I b ,I c}>10min{I a ,I b ,I c}, and the first preset condition is not met. If the third preset condition is met, it indicates that the internal communication of the fault indicator is normal, but the telemetry data is abnormal. If there is a sixth preset number of telemetry messages in the above-mentioned second preset number of continuous telemetry messages that meet the third preset condition, a telemetry data abnormality alarm can be output at this time to remind the operation and maintenance personnel to find the cause of the telemetry data abnormality. For example, the second preset number is 5, and the sixth preset number is also 5. Then, when all 5 groups of continuous telemetry data meet the third preset condition, a telemetry data abnormality alarm can be output at this time. Afterwards, the second preset number of continuous telemetry messages can be updated according to the third preset rule, and the step of determining the matching degree of the continuous telemetry messages with the preset condition can be returned to, until the updated internal communication abnormality level reaches the preset level threshold. By setting the third preset condition, the embodiment of the present application can effectively determine the situation where the internal communication of the fault indicator is normal but the telemetry data is abnormal, which is conducive to helping operation and maintenance personnel to quickly analyze and improve analysis efficiency.

[0058] Furthermore, the embodiment of the present application provides another method for detecting abnormal communication within a fault indicator, such as Figure 4 As shown, the method includes:

[0059] First, read the list of all fault indicators that have established a model on the master station side, and determine each fault indicator in the fault indicator list. Then, set the initial value (i.e., the first initial value) of the abnormal level (internal communication abnormal level) R of each fault indicator to 0, and set the initial value (i.e., the second initial value) of the flag F to 0. The control end on the master station side can receive the message sent by the terminal (fault indicator) frame by frame. Here, the message includes the telesignal message and the telemetry message. After receiving the message, the telesignal message and the telemetry message can be analyzed separately. With respect to the telesignal message, the FIFO method can be used to continuously store two sets of telesignal data. After that, it can be determined whether the two sets of continuous telesignal data are a repetition of one fault telesignal + one reset telesignal. If not, then R=R+1 can be set to update the abnormal level. If so, then R=0 can be set to clear the two consecutive sets of telesignal messages. For telemetry messages, FIFO can be used to continuously store five sets of telemetry data, and then the matching of the five sets of telemetry data with various conditions can be determined. Among them, condition A (the first preset condition) is: one or two phase current values ​​of the three-phase current value are 0, and the remaining phase current value is higher than the threshold value I0=10A; condition B (the second preset condition) is: the three-phase current value is 0; condition C (the third preset condition) is: when condition A is not met, and the three-phase current value meets max{I a ,I b ,I c}>10min{I a ,I b ,I cIf three of five consecutive telemetry data sets meet condition A, then R = R + 1 and the abnormality level can be updated. If all five consecutive telemetry data sets meet condition B, then R = R + 1 and F is set to 1. If at least three of five consecutive telemetry data sets meet condition B, but not all meet condition B, then R = R + 1 and F is set to 0 and then not set to 1 again. If all five consecutive telemetry data sets meet condition C, a telemetry data abnormality alarm can be output. Afterwards, the five consecutive telemetry data sets can be cleared. Whenever the abnormality level is updated, it can be determined whether the updated abnormality level is greater than or equal to 10. If so, the ledger information of the corresponding fault indicator can be printed, and further judgment can be made whether the flag bit is equal to 1. If the flag bit is equal to 1, it is necessary to print and confirm whether the fault indicator is mounted on the no-load line, so as to determine whether the abnormality level greater than 10 is caused by the fault indicator being mounted on the no-load line; if the flag bit is not equal to 1, the communication abnormality between the terminal (fault indicator) collection unit and the acquisition unit can be printed. If the updated abnormality level is less than 10, then the step of receiving the message frame by frame at the control end on the master station side can be returned.
