Therefore, the electricity consumption has increased year by year. Correspondingly, the laying and maintenance of power equipment have also become the daily work of each power company.

[0003] Among them, the daily work of power companies includes the laying of high-voltage lines, the construction of electric towers, the construction of substations, and the daily maintenance of transformers. For high-voltage lines, electric towers or substations, people have less daily contact. What residents come into contact with the most in their daily life and work are the transformers set up everywhere. Existing transformers generally have signs saying "Danger! High Voltage. Keep Away", but there is a lack of protection for the operation of the transformer itself and early warnings for the transformer in case of collision or emergencies. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Figure 1 Shows a flowchart of a transformer alarm method of the present invention;

[0062] Figure 2 Shows a block diagram of a transformer alarm system of the present invention. DETAILED DESCRIPTION

[0063] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0064] Many specific details are set forth in the following description in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those specifically described herein, and therefore, the scope of the present invention is not limited by the specific embodiments disclosed below.

[0065] Figure 1 Shows a flowchart of a transformer alarm method of the present application.

[0066] As Figure 1 shown, the present application discloses a transformer alarm method, including the following steps:

[0067] S102, obtaining environmental data of the location where the transformer is located based on a preset sensor group, and comparing parameters based on the environmental data with threshold limits to give an alarm;

[0068] S104. Obtain the operation data of the transformer and perform type analysis based on the operation data. The operation data includes control data, interface data, and self-check data.

[0069] S106. Perform closed-loop detection and alarm based on the control data.

[0070] S108. Perform attribute recognition and alarm based on the interface data.

[0071] S110. Perform threshold judgment and alarm based on the self-check data. The self-check data includes self-check temperature value, self-check collision value, and operation status value.

[0072] It should be noted that in this embodiment, when alarming the transformer, it includes the operation data alarm of the transformer itself and the external environment alarm where the transformer is located. When applied to the external environment alarm scenario of the transformer, obtain the environmental data of the location where the transformer is located based on a preset sensor group, such as obtaining environmental temperature or water level value and other environmental data, and then compare the environmental data with the threshold limit value to perform alarm. That is, if the environmental temperature is higher than the corresponding environmental temperature threshold limit value, an alarm is issued, and / or when the water level value is higher than the corresponding water level threshold limit value, an alarm is also issued. At this time, the alarm method includes reminding the background of the transformer equipment operation system or reminding the user terminal intelligent device responsible for the current transformer operation and maintenance through mobile communication (such as 4G / 5G).

[0073] Furthermore, in the operation data alarm scenario of the transformer itself, obtain the operation data of the transformer to distinguish types to obtain the control data, the interface data, and the self-check data. The control data includes the control parameters input to the current transformer. The interface data includes the access signal parameters accessed to the transformer through a preset interface. The self-check data includes the self-check operation parameters during the operation of the transformer. Specifically, perform closed-loop detection and alarm based on the control data. The detailed description is shown in the following explanation. For the interface data, identify the attributes of the access signal to perform alarm. Correspondingly, since the real-time self-check data includes the corresponding self-check temperature value, the self-check collision value, and the operation status value, and the operation status value includes electrical signal data such as current and voltage, once any parameter in the self-check data exceeds the corresponding limit value, an alarm is also issued. Correspondingly, the alarm method based on the operation data also includes reminding the background of the transformer equipment operation system or reminding the user terminal intelligent device responsible for the current transformer operation and maintenance through mobile communication (such as 4G / 5G).

[0074] According to an embodiment of the present invention, obtaining environmental data of the location where the transformer is located based on a preset sensor group, and comparing parameters based on the environmental data with threshold limits for alarming, specifically includes:

[0075] Obtaining the environmental data based on the sensor group, where the sensor group at least includes a temperature sensor, a vibration sensor, a water level sensor, and a humidity sensor, and the obtained environmental data at least includes environmental temperature, vibration value, water level value, and environmental humidity;

[0076] Comparing parameters based on the environmental data with the corresponding threshold limits, where when any of the environmental data exceeds the corresponding threshold limit, an alarm reminder is output.

[0077] It should be noted that in this embodiment, it is described in the above embodiment that alarming is performed based on obtaining the environmental data of the location where the transformer is located by the sensor group. For example, obtaining environmental temperature or water level value. Correspondingly, in this embodiment, the sensor group at least includes a temperature sensor, a vibration sensor, a water level sensor, and a humidity sensor, and the obtained environmental data at least includes environmental temperature, vibration value, water level value, and environmental humidity. Thus, based on the obtained environmental data, a comparison is made with the corresponding threshold limits to output an alarm reminder. Specifically, taking the temperature sensor as an example, when the detected environmental temperature is higher than the corresponding environmental temperature threshold limit, a temperature over-limit alarm reminder is output, so that the background user can timely understand the corresponding temperature anomaly information, and thus can obtain the feedback control data to perform emergency avoidance in time, such as performing a power-off operation, etc. For example, when a fire occurs at the location where the transformer is located, when the fire becomes more and more fierce, the temperature will gradually rise. At this time, in order to avoid secondary damage caused by a short circuit in the circuit, performing a power-off operation at this time can avoid the occurrence of a short circuit in the circuit. Taking the vibration sensor as an example, similarly, when the detected vibration frequency is higher than the corresponding environmental vibration threshold limit, a vibration over-limit alarm reminder is output, so that the background user can timely understand the corresponding vibration anomaly information, and thus can obtain the feedback control data to perform emergency avoidance in time. For example, when an earthquake occurs, a power-off operation can be performed first to avoid the occurrence of secondary damage.

[0078] According to an embodiment of the present invention, obtaining the operation data of the transformer, and performing type analysis based on the operation data, specifically includes:

[0079] Obtaining the operation data of the transformer based on the edge gateway side provided on the transformer;

[0080] Performing data type factor division based on the operation data to obtain different types of operation data;

[0081] When a control data factor is recognized, the corresponding recognized operation data is classified as the control data;

[0082] When the interface data factor is recognized, the corresponding recognized operation data is divided into the interface data;

[0083] When the self-check data factor is recognized, the corresponding recognized operation data is divided into the self-check data.

[0084] It should be noted that in this embodiment, it is described in the above embodiment that the transformer can send an alarm reminder to the system background through mobile communication or link form. Therefore, the operation data of the transformer can be obtained from the edge gateway side set on the transformer, and then different types of operation data can be obtained through type factor division. Specifically, when the control data factor is recognized, the corresponding recognized operation data is divided into the control data for subsequent steps; when the interface data factor is recognized, the corresponding recognized operation data is divided into the interface data for subsequent steps; when the self-check data factor is recognized, the corresponding recognized operation data is divided into the self-check data for subsequent steps.

[0085] According to an embodiment of the present invention, the closed-loop detection and alarm based on the control data specifically includes:

[0086] When the control data is recognized, obtain the control path corresponding to the current control data, the control path includes a base station path, an Ethernet path, and a local path, and the control data corresponds to one of the control paths;

[0087] Based on the current control path, a detection path is filtered out, and the control data is sent back to the user side based on the detection path for closed-loop detection, where,

[0088] When the closed-loop detection result is true, the current control data is allowed to operate, otherwise it is not allowed to operate and an alarm is issued.

[0089] It should be noted that in this embodiment, when the transformer conducts data communication with the background user, there are three control paths in total, namely the base station path, the Ethernet path, and the local path. Among them, the base station path is for communicating with the user responsible for the current operation and maintenance of the transformer. The Ethernet path is for communicating with the background of the current transformer equipment operation system through a link. And the local path (such as RS458) is for facilitating on-site operations by the personnel responsible for the operation and maintenance of the transformer. Specifically, the purpose of the closed-loop detection is to form a protection mechanism to prevent the transformer from being illegally invaded and controlled. Specifically, when the identified control data comes from the base station path, closed-loop detection data will be sent to the system background of the Ethernet path. If the closed-loop detection result feedback from the system background of the Ethernet path is true, the control data of the current base station path is allowed to perform operations. When the identified control data comes from the system background of the Ethernet path, closed-loop detection data will be sent to the intelligent device of the user side responsible for the current operation and maintenance of the transformer on the base station path. If the closed-loop detection result feedback from the intelligent device of the user side on the base station path is true, the control data of the current Ethernet path is allowed to perform operations. When the identified control data comes from the local path, closed-loop detection data will be sent to the intelligent device of the user side responsible for the current operation and maintenance of the transformer on the base station path and / or closed-loop detection data will be sent to the system background of the Ethernet path. If the received feedback of the closed-loop detection result is true, the control data of the current local path is allowed to perform operations.

[0090] According to an embodiment of the present invention, the attribute recognition and alarm based on the interface data specifically include:

[0091] When the interface data is recognized, obtain the interface attribute corresponding to the current interface data;

[0092] Based on the interface attribute, perform local verification and / or cloud verification and obtain the feedback verification result, where

[0093] If the verification result shows illegal access, output an alarm reminder.

[0094] It should be noted that in this embodiment, since the transformer has an external interface, when the interface data is recognized, it is necessary to recognize the interface attribute corresponding to the current interface data to prevent illegal intrusion events. Specifically, local verification and / or cloud verification can be performed based on the interface data, and the corresponding verification result can be obtained. Among them, if the verification result shows illegal access, an alarm reminder is output. It should be noted that the local path closed-loop detection described in the above embodiment is for the control data itself, rather than the interface of the local path. Therefore, in this embodiment, the alarm is made through interface attribute recognition.

[0095] According to an embodiment of the present invention, the threshold judgment and alarm based on the self-check data specifically include:

[0096] Alarm based on the self-check temperature value. When the self-check temperature value exceeds the self-check temperature limit, an alarm reminder is output.

[0097] Alarm based on the self-check collision value. When the self-check collision value exceeds the preset number of collisions and / or collision degree value, an alarm reminder is output.

[0098] Alarm based on the operation status value. When the operation status value shows an operation anomaly, an alarm reminder is output based on the corresponding operation anomaly.

[0099] It should be noted that in this embodiment, it is described in the above embodiment that when the transformer is in operation, it will feedback the self-check data of its own operation status. The self-check data includes the self-check temperature value, the self-check collision value, and the operation status value. The operation status value includes electrical signals such as current value and voltage value. Specifically, an alarm is made based on the self-check temperature value. When the self-check temperature value exceeds the self-check temperature limit, an alarm reminder is output. Correspondingly, the alarm reminder method also includes reminding the background of the transformer equipment operation system, or reminding the user-side intelligent device responsible for the current transformer operation and maintenance through mobile communication (such as 4G / 5G); an alarm is made based on the self-check collision value. When the self-check collision value exceeds the preset number of collisions and / or collision degree value, an alarm reminder is output; an alarm is made based on the operation status value. When the operation status value shows an operation anomaly, an alarm reminder is output based on the corresponding operation anomaly. Since the alarm methods are the same, they will not be elaborated here.

[0100] It is worth mentioning that the comparison based on the self-check collision value specifically includes:

[0101] Obtain the number of times of over-limit pressure received by the transformer based on the pressure sensor in the sensor group.

[0102] Obtain the deformation value corresponding to the transformer based on the capacitance ranging sensor in the sensor group.

[0103] Compare the number of times of over-limit pressure with the number of collisions, and compare the deformation value with the collision degree value.

[0104] It should be noted that in this embodiment, since it is described in the above embodiment that an alarm is made based on the self-check collision value. Specifically, when the self-check collision value exceeds the preset number of collisions and / or collision degree value, an alarm reminder is output. Specifically, the self-check collision value includes the number of over-limit pressures and the deformation value. When comparing, the number of over-limit pressures is compared with the number of collisions, and the deformation value is compared with the collision degree value. Among them, if the number of over-limit pressures is greater than the preset number of collisions, an alarm reminder is output, and / or if the deformation value is greater than the collision degree value, a corresponding alarm reminder is output. And when alarming, the corresponding danger information is synchronously output.

[0105] It is worth mentioning that the method further includes using a preset power amplifier for alarming, specifically including:

[0106] Obtain and distinguish the alarm type for outputting the alarm reminder, where

[0107] If the alarm type meets Class I, synchronous alarming is performed;

[0108] Otherwise, no synchronous alarm is made based on the preset power amplifier.

[0109] It should be noted that in this embodiment, since when the transformer is operating, it will alarm the system background or the user-side intelligent device responsible for the current transformer operation and maintenance. However, due to distance or duration limitations, there are some alarm types that need to be alarmed at the transformer site to alert people to avoid approaching. Specifically, the alarm type is identified to meet the Class I alarm and a preset power amplifier is used for synchronous alarming. Among them, the Class I alarm types can include environmental data alarms and self-check data alarms. For example, when the current value or voltage value in the self-check data exceeds the limit, an alarm needs to be made using the power amplifier at the transformer site to avoid people getting injured when approaching. And the power amplifier circuit is powered separately and the battery needs to be replaced regularly.

[0110] It is worth mentioning that the method further includes, when the identified control data comes from the local path, determining whether the received feedback of the closed-loop detection result is true, specifically including:

[0111] When it is identified that the control data comes from the local path, obtain the first feedback data of the base station path and / or obtain the second feedback data of the Ethernet path;

[0112] Make a judgment based on the first feedback data and the second feedback data, where

[0113] If the first feedback data shows that the closed-loop detection result is true while the second feedback data shows no result, it is determined that the current closed-loop detection result is true;

[0114] If the first feedback data shows that the closed-loop detection result is true while the second feedback data shows false, then it is determined that the current closed-loop detection result is false;

[0115] If the first feedback data shows that the closed-loop detection result is true while the second feedback data shows true, then it is determined that the current closed-loop detection result is true;

[0116] If the first feedback data shows that the closed-loop detection result is false while the second feedback data shows no display, then it is determined that the current closed-loop detection result is false;

[0117] If the first feedback data shows that the closed-loop detection result is false while the second feedback data shows false, then it is determined that the current closed-loop detection result is false;

[0118] If the first feedback data shows that the closed-loop detection result is false while the second feedback data shows true, then it is determined that the current closed-loop detection result is true;

[0119] If the first feedback data shows no display for the closed-loop detection result while the second feedback data shows no display, then it is determined that the current closed-loop detection result is false;

[0120] If the first feedback data shows no display for the closed-loop detection result while the second feedback data shows false, then it is determined that the current closed-loop detection result is false;

[0121] If the first feedback data shows no display for the closed-loop detection result while the second feedback data shows true, then it is determined that the current closed-loop detection result is true.

[0122] It should be noted that in this embodiment, since when the identified control data comes from the local path, closed-loop detection data is sent to the user-side intelligent device responsible for the current transformer operation and maintenance on the base station path and / or closed-loop detection data is sent to the system background on the Ethernet path, the received feedback will naturally include the first feedback data and / or the second feedback data. Therefore, it is necessary to judge different feedback scenarios. Specifically, the priority of the second feedback data is higher than that of the first feedback data, that is, when there is a display in the second feedback data, the display in the second feedback data is used as the final closed-loop detection result. For example, when the second feedback is false, the final closed-loop detection result is false. If there is no display in the second feedback data, the display in the first feedback data is used as the final closed-loop detection result. For example, if the second feedback data has no display and the first feedback data shows true, then the final closed-loop detection result is true. Among them, if both the first feedback data and the second feedback data have no display, the final closed-loop detection result is false.

[0123] Figure 2The block diagram of a transformer alarm system according to the present invention is shown.

[0124] As Figure 2 shown, the present invention discloses a transformer alarm system, including a memory and a processor. The memory includes a transformer alarm method program. When the transformer alarm method program is executed by the processor, the following steps are implemented:

[0125] Obtain the environmental data of the location where the transformer is located based on a preset sensor group, and compare the parameters of the environmental data with the threshold limits for alarm;

[0126] Obtain the operation data of the transformer, and perform type analysis based on the operation data. Among them, the operation data includes control data, interface data, and self-check data;

[0127] Perform closed-loop detection alarm based on the control data; and / or

[0128] Perform attribute recognition alarm based on the interface data; and / or

[0129] Perform threshold judgment alarm based on the self-check data. The self-check data includes self-check temperature value, self-check collision value, and operation status value.

[0130] It should be noted that in this embodiment, when alarming the transformer, it includes the operation data alarm of the transformer itself and the external environment alarm of the transformer. Among them, when applied to the external environment alarm scenario of the transformer, obtain the environmental data of the location where the transformer is located based on a preset sensor group, such as obtaining environmental temperature or water level value and other environmental data, so as to compare the parameters of the environmental data with the threshold limits for alarm. Among them, if the environmental temperature is higher than the corresponding environmental temperature threshold limit, an alarm is made, and / or when the water level value is higher than the corresponding water level threshold limit, an alarm is also made. At this time, the alarm method includes reminding the background of the transformer equipment operation system, or reminding the user terminal intelligent device responsible for the current transformer operation and maintenance through mobile communication (such as 4G / 5G).

[0131] Further, when alarming based on the operation data of the transformer itself, obtain the operation data of the transformer to distinguish types to obtain the control data, the interface data, and the self-check data. Among them, the control data includes the control parameters input to the current transformer, the interface data includes the access signal parameters accessed to the transformer through a preset interface, and the self-check data includes the self-check operation parameters during the operation of the transformer. Specifically, perform closed-loop detection and alarming based on the control data, and the detailed description is shown in the following description. For the interface data, identify the attributes of the access signal to perform alarming. Correspondingly, since the real-time self-check data includes the corresponding self-check temperature value, the self-check collision value, and the operation status value, and the operation status value includes electrical signal data such as current and voltage, once any parameter in the self-check data exceeds the corresponding limit value, alarming is also performed. Correspondingly, the method of alarming based on the operation data also includes reminding the background of the transformer equipment operation system, or reminding the user-end intelligent device responsible for the operation and maintenance of the current transformer through mobile communication (such as 4G / 5G).

[0132] According to an embodiment of the present invention, obtain the environmental data of the location where the transformer is located based on a preset sensor group, and compare the environmental data with a threshold limit value to perform alarming, specifically including:

[0133] Obtain the environmental data based on the sensor group. Among them, the sensor group at least includes a temperature sensor, a vibration sensor, a water level sensor, and a humidity sensor, and the obtained environmental data at least includes the environmental temperature, the vibration value, the water level value, and the environmental humidity;

[0134] Compare the environmental data with the corresponding threshold limit value. When any of the environmental data exceeds the corresponding threshold limit value, output an alarm reminder.

[0135] It should be noted that in this embodiment, in the above embodiment, it is described that the environmental data where the transformer is located is obtained based on the sensor group for warning, for example, the environmental temperature or the water level value is obtained. Correspondingly, in this embodiment, the sensor group at least includes a temperature sensor, a vibration sensor, a water level sensor, and a humidity sensor, and the obtained environmental data at least includes the environmental temperature, the vibration value, the water level value, and the environmental humidity. Then, based on the corresponding obtained environmental data, it is compared with the corresponding threshold limits to output a warning reminder. Specifically, taking the temperature sensor as an example, when the detected environmental temperature is higher than the corresponding environmental temperature threshold limit, a temperature over-limit warning reminder is output, so that the background user can timely learn the corresponding temperature anomaly information, and then the feedback control data can be obtained to perform emergency avoidance in time, such as performing a power-off operation, etc. For example, when a fire occurs at the location where the transformer is located, when the fire becomes more and more fierce, the temperature will gradually rise. At this time, in order to avoid secondary damage caused by a short circuit in the circuit, performing a power-off operation at this time can avoid the occurrence of a short circuit in the circuit. Taking the vibration sensor as an example, similarly, when the detected vibration frequency is higher than the corresponding environmental vibration threshold limit, a vibration over-limit warning reminder is output, so that the background user can timely learn the corresponding vibration anomaly information, and then the feedback control data can be obtained to perform emergency avoidance in time. For example, when an earthquake occurs, a power-off operation can be performed first to avoid secondary damage.

[0136] According to an embodiment of the present invention, obtaining the operation data of the transformer and performing type analysis based on the operation data specifically includes:

[0137] Obtaining the operation data of the transformer based on the edge gateway side provided on the transformer;

[0138] Performing data type factor division on the operation data to obtain different types of operation data;

[0139] When the control data factor is recognized, the corresponding recognized operation data is classified as the control data;

[0140] When the interface data factor is recognized, the corresponding recognized operation data is classified as the interface data;

[0141] When the self-check data factor is recognized, the corresponding recognized operation data is classified as the self-check data.

[0142] It should be noted that in this embodiment, it is described in the above embodiment that the transformer can send an alarm reminder to the system background through mobile communication or link form. Therefore, the operation data of the transformer can be obtained from the edge gateway side set on the transformer, and then different types of operation data can be obtained through type factor division. Specifically, when the control data factor is recognized, the corresponding recognized operation data is divided into the control data for subsequent steps; when the interface data factor is recognized, the corresponding recognized operation data is divided into the interface data for subsequent steps; when the self-check data factor is recognized, the corresponding recognized operation data is divided into the self-check data for subsequent steps.

[0143] According to an embodiment of the present invention, the closed-loop detection and alarm based on the control data specifically includes:

[0144] When the control data is recognized, obtain the control path corresponding to the current control data. The control path includes a base station path, an Ethernet path, and a local path, and the control data corresponds to one of the control paths;

[0145] Based on the current control path, a detection path is filtered out, and the control data is sent back to the user side based on the detection path for closed-loop detection, where

[0146] When the closed-loop detection result is true, the current control data is allowed to perform operations, otherwise the operations are not allowed and an alarm is issued.

[0147] It should be noted that in this embodiment, when the transformer communicates with the background user, there are three control paths in total, namely the base station path, the Ethernet path, and the local path. Among them, the base station path is for communicating with the user responsible for the current transformer operation and maintenance, the Ethernet path is for communicating with the background of the current transformer equipment operation system through the link, and the local path (such as RS458) is for facilitating on-site operation by the personnel responsible for the transformer operation and maintenance. Specifically, the purpose of the closed-loop detection is to form a protection mechanism to prevent the transformer from being illegally invaded and controlled. Specifically, when the identified control data comes from the base station path, closed-loop detection data will be sent to the system background of the Ethernet path. If the closed-loop detection result feedback from the system background of the Ethernet path is true, the control data of the current base station path is allowed to perform operations; when the identified control data comes from the system background of the Ethernet path, closed-loop detection data will be sent to the intelligent device of the user side responsible for the current transformer operation and maintenance in the base station path. If the closed-loop detection result feedback from the intelligent device of the user side in the base station path is true, the control data of the current Ethernet path is allowed to perform operations; when the identified control data comes from the local path, closed-loop detection data will be sent to the intelligent device of the user side responsible for the current transformer operation and maintenance in the base station path and / or closed-loop detection data will be sent to the system background of the Ethernet path. If the received feedback of the closed-loop detection result is true, the control data of the current local path is allowed to perform operations.

[0148] According to the embodiment of the present invention, the attribute recognition and warning based on the interface data specifically include:

[0149] When the interface data is recognized, obtain the interface attribute corresponding to the current interface data;

[0150] Based on the interface attribute, perform local verification and / or cloud verification and obtain the feedback verification result, where

[0151] If the verification result shows illegal access, output a warning reminder.

[0152] It should be noted that in this embodiment, since the transformer has an external interface, when the interface data is recognized, it is necessary to recognize the interface attribute corresponding to the current interface data to prevent illegal intrusion events. Specifically, local verification and / or cloud verification can be performed based on the interface data, and the corresponding verification result can be obtained. Among them, if the verification result shows illegal access, a warning reminder is output. It should be noted that the local path closed-loop detection described in the above embodiment is for the control data itself, rather than the interface of the local path. Therefore, in this embodiment, the warning is performed through interface attribute recognition.

[0153] According to an embodiment of the present invention, the threshold judgment and alarm based on the self-check data specifically include:

[0154] Alarm based on the self-check temperature value. When the self-check temperature value exceeds the self-check temperature limit value, an alarm reminder is output.

[0155] Alarm based on the self-check collision value. When the self-check collision value exceeds the preset number of collisions and / or collision degree value, an alarm reminder is output.

[0156] Alarm based on the operation status value. When the operation status value shows an operation anomaly, an alarm reminder is output based on the corresponding operation anomaly.

[0157] It should be noted that in this embodiment, in the above embodiment, it is described that when the transformer is in operation, it will feedback the self-check data of its own operation status. Among them, the self-check data includes the self-check temperature value, the self-check collision value, and the operation status value. The operation status value includes electrical signals such as current value and voltage value. Specifically, alarm is based on the self-check temperature value. When the self-check temperature value exceeds the self-check temperature limit value, an alarm reminder is output. Correspondingly, the way of alarm reminder also includes reminding the background of the transformer equipment operation system, or reminding the user-side intelligent device responsible for the current transformer operation and maintenance through mobile communication (such as 4G / 5G); alarm is based on the self-check collision value. When the self-check collision value exceeds the preset number of collisions and / or collision degree value, an alarm reminder is output; alarm is based on the operation status value. When the operation status value shows an operation anomaly, an alarm reminder is output based on the corresponding operation anomaly. Since the alarm methods are the same, they will not be elaborated here.

[0158] It is worth mentioning that the comparison based on the self-check collision value specifically includes:

[0159] Obtain the number of times of over-limit pressure received by the transformer based on the pressure sensor in the sensor group.

[0160] Obtain the deformation value corresponding to the transformer based on the capacitance ranging sensor in the sensor group.

[0161] Compare the number of times of over-limit pressure with the number of collisions, and compare the deformation value with the collision degree value.

[0162] It should be noted that in this embodiment, since it is described in the above embodiment that an alarm is made based on the self-checking collision value. Specifically, when the self-checking collision value exceeds the preset number of collisions and / or the collision degree value, an alarm reminder is output. Specifically, the self-checking collision value includes the number of over-limit pressures and the deformation value. When comparing, the number of over-limit pressures is compared with the number of collisions, and the deformation value is compared with the collision degree value. Among them, if the number of over-limit pressures is greater than the preset number of collisions, an alarm reminder is output, and / or if the deformation value is greater than the collision degree value, a corresponding alarm reminder is output. And when an alarm is made, the corresponding danger information is synchronously output.

[0163] It is worth mentioning that the method further includes using a preset power amplifier for alarming, specifically including:

[0164] Obtain and distinguish the alarm types for which alarm reminders are output, where

[0165] If the alarm type meets Class I, synchronous alarming is performed;

[0166] Otherwise, no synchronous alarm is made based on the preset power amplifier.

[0167] It should be noted that in this embodiment, since when the transformer is operating, it will alarm the system background or the user-side intelligent device responsible for the current transformer operation and maintenance. However, due to distance or duration limitations, there are some alarm types that need to be alarmed at the transformer site to alert people to avoid approaching. Specifically, the alarm types are identified so that synchronous alarming is performed for the alarms that meet Class I using a preset power amplifier. Among them, the alarm types of Class I can include environmental data alarms and self-checking data alarms. For example, when the current value or voltage value in the self-checking data exceeds the limit, it is necessary to use the power amplifier at the transformer site to alarm to avoid people getting injured when approaching. And the power amplifier circuit is independently powered and the battery needs to be replaced regularly.

[0168] It is worth mentioning that the method further includes, when it is recognized that the control data comes from the local path, determining whether the received feedback of the closed-loop detection result is true, specifically including:

[0169] When it is recognized that the control data comes from the local path, obtain the first feedback data of the base station path and / or obtain the second feedback data of the Ethernet path;

[0170] Make a judgment based on the first feedback data and the second feedback data, where

[0171] If the first feedback data shows that the closed-loop detection result is true while the second feedback data shows no result, it is determined that the current closed-loop detection result is true;

[0172] If the first feedback data shows that the closed-loop detection result is true while the second feedback data shows false, then it is determined that the current closed-loop detection result is false;

[0173] If the first feedback data shows that the closed-loop detection result is true while the second feedback data shows true, then it is determined that the current closed-loop detection result is true;

[0174] If the first feedback data shows that the closed-loop detection result is false while the second feedback data shows no display, then it is determined that the current closed-loop detection result is false;

[0175] If the first feedback data shows that the closed-loop detection result is false while the second feedback data shows false, then it is determined that the current closed-loop detection result is false;

[0176] If the first feedback data shows that the closed-loop detection result is false while the second feedback data shows true, then it is determined that the current closed-loop detection result is true;

[0177] If the first feedback data shows no display for the closed-loop detection result while the second feedback data shows no display, then it is determined that the current closed-loop detection result is false;

[0178] If the first feedback data shows no display for the closed-loop detection result while the second feedback data shows false, then it is determined that the current closed-loop detection result is false;

[0179] If the first feedback data shows no display for the closed-loop detection result while the second feedback data shows true, then it is determined that the current closed-loop detection result is true.

[0180] It should be noted that in this embodiment, since when the identified control data comes from the local path, closed-loop detection data is sent to the user-side intelligent device responsible for the current transformer operation and maintenance on the base station path and / or closed-loop detection data is sent to the system background on the Ethernet path, the received feedback will naturally include the first feedback data and / or the second feedback data. Therefore, it is necessary to judge different feedback scenarios. Specifically, the priority of the second feedback data is higher than that of the first feedback data, that is, when there is a display in the second feedback data, the display in the second feedback data is taken as the final closed-loop detection result. For example, when the second feedback is false, the final closed-loop detection result is false. If there is no display in the second feedback data, the display in the first feedback data is taken as the final closed-loop detection result. For example, when the second feedback data has no display and the first feedback data shows true, the final closed-loop detection result is true. Among them, when both the first feedback data and the second feedback data have no display, the final closed-loop detection result is false.
