It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Wherein, a communication connection is established between the concentrator 102 and the intelligent insulator string 104. The concentrator 102 monitors a networking request instruction broadcasted by an intelligent insulator string which is hung with a power transmission line to be tested in response to a triggering condition of finishing initialization of the concentrator; the networking request instruction is an instruction sent by at least one intelligent insulator in the intelligent insulator string after initialization is completed; under the condition of monitoring the networking request instruction, the concentrator 102 establishes communication connection with the intelligent insulator which sends the networking request instruction; under the condition that communication connection with all intelligent insulators in the intelligent insulator string is successfully established, the concentrator 102 sends a monitoring instruction to each intelligent insulator in the intelligent insulator string; the monitoring instruction is used for indicating each intelligent insulator to carry out voltage monitoring on the power transmission line to be detected according to a preset monitoring time interval so as to obtain voltage monitoring data; the concentrator 102 determines a voltage measurement result corresponding to the power transmission line to be measured according to the voltage monitoring data returned by each intelligent insulator. The intelligent insulator string 104 may be composed of at least one intelligent insulator.

In some embodiments, as shown in fig. 2, a non-invasive voltage measurement method based on a smart insulator is provided, which is illustrated by applying the method to the concentrator in fig. 1, and includes the following steps:

step S202, in response to the trigger condition of the initialization completion of the concentrator, monitoring a networking request instruction broadcasted by an intelligent insulator string which is connected with a power transmission line to be tested in a hanging manner; the networking request instruction is an instruction sent by at least one intelligent insulator in the intelligent insulator string after initialization is completed.

The concentrator may refer to a central management device and a control device of a remote centralized meter reading system, and in practical application, the concentrator may include a passive concentrator, an active concentrator, and an intelligent concentrator.

As an example, as shown in fig. 3, the concentrator may include a concentrator display screen that may be used to display necessary information, a concentrator signal indicator light that may be used to visually indicate the current state of the concentrator, a concentrator operation panel area that may be used for voltage measurement personnel to set and data input the concentrator, and a concentrator communication antenna that may be used to transmit and listen for communication signals.

The trigger condition may refer to a condition for characterizing that the concentrator has completed initialization.

The power transmission line to be measured can be a power transmission line in a power transmission line which needs to be subjected to voltage measurement in a power system.

In one exemplary embodiment, the intelligent insulator string may refer to a device composed of at least one intelligent insulator, and in practical applications, the intelligent insulator string may be composed of a plurality of intelligent insulators, wherein, except for the last intelligent insulator, the metal rod of the intelligent insulator is connected to the metal cap of the next intelligent insulator.

The networking request instruction may be an instruction sent by the intelligent insulator and used for requesting the concentrator to establish networking communication connection.

As an example, the concentrator responds to the activation operation of the user, the concentrator activates power-on and enters an initialization program, and in the case that the initialization of the concentrator is completed, the bluetooth module of the concentrator is in a full-channel monitoring state to monitor a networking request instruction sent by the intelligent insulator.

And step S204, establishing communication connection with the intelligent insulator which sends the networking request command under the condition of monitoring the networking request command.

The intelligent insulator can be obtained by introducing an electric field measuring module, a data conditioning module, a data processing module and a communication module into the insulator in a manufacturing stage on the basis of the common insulator, and a large amount of glass insulators are adopted in the existing power transmission line, so that the intelligent insulator can be obtained by taking the glass insulators as modification objects, but the intelligent insulator still meets the requirements of a power system on the insulator, particularly the requirements on electrical performance and mechanical performance.

As an example, the core of the concentrator for implementing networking communication with the intelligent insulators is a master-slave communication technology, the intelligent insulators serve as slaves, and the concentrator serves as a master, that is, each intelligent insulator is firstly connected with the concentrator, and then the concentrator divides the intelligent insulators communicatively connected with the concentrator into one group, thereby implementing networking of the intelligent insulators in the intelligent insulator string.

As an example, when the concentrator monitors a networking request command sent by the intelligent insulator, the concentrator sends a networking confirmation command to the intelligent insulator which sends the networking request command, and after the intelligent insulator receives the networking confirmation command sent by the concentrator, the intelligent insulator sends a networking confirmation message to the concentrator, so that the concentrator and the intelligent insulator establish a communication connection.

Step S206, under the condition that communication connection with all intelligent insulators in the intelligent insulator string is successfully established, sending a monitoring instruction to each intelligent insulator in the intelligent insulator string; the monitoring instruction is used for indicating each intelligent insulator to carry out voltage monitoring on the power transmission line to be monitored according to a preset monitoring time interval, and voltage monitoring data are obtained.

The monitoring instruction can be an instruction for instructing the intelligent insulator to monitor the voltage of the power transmission line to be monitored.

The monitoring time interval can be a time interval between two continuous voltage monitoring when the intelligent insulator is characterized to carry out voltage monitoring on the power transmission line to be detected, and in practical application, the preset time interval can comprise 1 second, 2 seconds and 3 seconds.

The voltage monitoring data may be voltage data obtained by monitoring the voltage of the power transmission line to be detected by the intelligent insulator in response to the monitoring instruction, and in practical application, the voltage monitoring data may include the voltage born by the intelligent insulator.

As an example, after the concentrator establishes communication connection with the intelligent insulator corresponding to the networking request instruction, the concentrator continuously monitors, records the intelligent insulator in communication connection with the concentrator, and numbers the intelligent insulators in sequence until the concentrator successfully establishes communication connection with all the intelligent insulators in the intelligent insulator string, and in response to the instruction, the concentrator sends a monitoring instruction to the intelligent insulator in communication connection with the concentrator, so that the intelligent insulator receiving the monitoring instruction monitors the voltage of the transmission line to be monitored according to a preset monitoring time interval, and the intelligent insulator obtains voltage monitoring data.

And S208, determining a voltage measurement result corresponding to the power transmission line to be measured according to the voltage monitoring data returned by each intelligent insulator.

The voltage measurement result may be obtained by the concentrator according to each voltage monitoring data, and is used to represent voltage data of the voltage on the power transmission line to be measured.

As an example, the intelligent insulators send the monitored voltage monitoring data to the concentrator, and the concentrator adds the voltage monitoring data returned by each intelligent insulator in sequence to obtain a voltage measurement result corresponding to the power transmission line to be measured.

In the non-invasive voltage measuring method of the intelligent insulator, the concentrator is ensured to complete initialization by responding to a trigger condition of the initialization completion of the concentrator, the concentrator monitors a networking request command broadcasted by an intelligent insulator string which is connected with a transmission line to be measured after all intelligent insulators in the intelligent insulator string are initialized, so that the concentrator establishes communication connection with the intelligent insulator which sends the networking request command after the concentrator monitors the networking request command, the concentrator further sends a monitoring command to each intelligent insulator in the intelligent insulator string after the concentrator successfully establishes communication connection with all intelligent insulators in the intelligent insulator string, so that after the intelligent insulators receive the monitoring command in series, the intelligent insulators monitor the voltage of the transmission line to be measured according to a preset monitoring time interval, thereby obtaining voltage monitoring data, the concentrator determines a voltage measuring result corresponding to the transmission line to be measured according to the voltage monitoring data returned by each intelligent insulator, the concentrator and the intelligent insulators establish communication connection with each intelligent insulator in a broadcasting and monitoring mode after the initialization completion, so that the concentrator sends the monitoring command to the intelligent insulators so as to make the intelligent insulators monitor the voltage of the transmission line to be measured, thereby obtaining the voltage data corresponding to the voltage of the intelligent insulators to be measured by the intelligent insulator string, respectively using the monitoring voltage data to be measured by the concentrator and the intelligent insulators to be measured, and the intelligent insulators to be measured by utilizing the intelligent insulators to be measured, the intelligent insulator string to be measured, thereby obtain the voltage data to be measured by the intelligent insulators in the intelligent insulators, thereby improving the efficiency of voltage measurement in the power system.

In some embodiments, the establishing a communication connection with the intelligent insulator that issues the networking request instruction includes:

sending a networking confirmation instruction to the intelligent insulator; the networking confirmation instruction is used for indicating the intelligent insulator to send confirmation networking information; and the confirmed networking information comprises the MAC address, the unique identification ID and the communication time interval of the intelligent insulator.

The networking confirmation instruction may refer to an instruction for representing that the concentrator confirms a request for establishing communication connection with the intelligent insulator, and in practical application, the networking confirmation instruction may include information such as an MAC address, a unique identifier ID, and a communication time interval of the concentrator.

As an example, when the concentrator monitors a networking request sent by the intelligent insulator, the concentrator sends a networking confirmation instruction to the intelligent insulator, where the networking confirmation instruction includes an MAC address and a unique identification ID of the concentrator, and in practical applications, the MAC address and the unique identification ID may be used by the intelligent insulator to send voltage measurement data and information for identifying the concentrator to the concentrator.

The confirmation networking information may refer to information required when the intelligent insulator and the concentrator are represented to establish communication connection, and in practical application, the networking confirmation information may include an MAC address, a unique identifier ID, and a communication time interval of the intelligent insulator.

As an example, after receiving the networking confirmation instruction, the intelligent insulator sends confirmation networking information to the concentrator, and after receiving the confirmation networking information sent by the intelligent insulator, the concentrator establishes communication connection with the intelligent insulator corresponding to the confirmation networking information.

According to the technical scheme, the concentrator and the intelligent insulator are connected in a communication mode through the networking confirmation instruction and the networking information confirmation receiving and sending between the concentrator and the intelligent insulator, so that the concentrator and the intelligent insulator can be connected in a communication mode, voltage monitoring data sent by the intelligent insulator can be timely transmitted to the concentrator, and the voltage measurement efficiency is improved.

In some embodiments, the method further comprises:

and determining the quantity information of the intelligent insulators which are in communication connection with the concentrator at present according to the confirmed networking information.

The quantity information may indicate the quantity of the intelligent insulators currently establishing communication connection with the concentrator, and in practical application, the quantity information may include 1 quantity, 2 quantities, and 3 quantities.

As an example, after receiving the networking confirmation information sent by the intelligent insulator, the concentrator numbers the intelligent insulator in order to determine the number of the intelligent insulator in the intelligent insulator currently in communication connection with the concentrator, and the concentrator determines the number corresponding to the intelligent insulator as the number information of the intelligent insulators currently in communication connection with the concentrator.

As an example, after each intelligent insulator is manufactured, the power transmission line on which the intelligent insulator is installed cannot be determined in advance, and information of other intelligent insulators in an intelligent insulator string to which the intelligent insulator belongs cannot be determined in advance, after each intelligent insulator is manufactured and leaves a factory, the intelligent insulators are provided with independent ID numbers similar to identity cards, 10 intelligent insulators are taken as examples and are respectively numbered 00, 01, 02, \8230; \, 08, 09, the number of the intelligent insulators in the intelligent insulator string used for measuring the voltage of the power transmission line to be measured depends on the voltage grade corresponding to the voltage of the power transmission line to be measured, and assuming that 3 intelligent insulators are required for a voltage measurement task of a certain power transmission line to be measured to form an intelligent insulator string required for measuring the voltage, then 3 intelligent insulators are selected from the 10 intelligent insulators, and there are many possible combinations, therefore, after the intelligent insulator string is installed on site, an intelligent insulator string in the intelligent insulator string needs to start a communication module, and all the intelligent insulators in the intelligent insulator string belong to the intelligent insulator string are determined by a self-networking technology.

The quantity requirement can be the quantity of intelligent insulators needed by measuring the electric measurement of the power transmission line to be measured, and in practical application, the quantity requirement can be preset by a voltage measurement worker.

As an example, corresponding to a specific voltage class, a voltage measurement worker presets a quantity requirement, that is, the voltage measurement worker presets the quantity of the intelligent insulators in the intelligent insulator string, and if the quantity of the intelligent insulators currently establishing communication connection with the concentrator is smaller than the preset quantity requirement, the concentrator continues to monitor until the quantity of the intelligent insulators currently establishing communication connection with the concentrator is equal to the preset quantity requirement; if the number of the intelligent insulators which are in communication connection with the concentrator at present is equal to the preset number requirement, the concentrator judges that the concentrator is in communication connection with all the intelligent insulators in the intelligent insulator string successfully at the moment, and then the concentrator sends a monitoring instruction to the intelligent insulators which are in communication connection with the concentrator.

According to the technical scheme, whether the concentrator is successfully in communication connection with all intelligent insulators in the intelligent insulator string is judged by comparing the size relation between the number of the intelligent insulators in communication connection with the concentrator and the preset number requirement, the concentrator can be guaranteed to receive voltage monitoring data monitored by all the intelligent insulators in the intelligent insulator string, the integrity of the data is guaranteed, and the measurement accuracy of voltage measurement is improved.

In some embodiments, as shown in fig. 4, a non-invasive voltage measurement method based on an intelligent insulator is provided, which is described by taking the method as an example for the intelligent insulator in fig. 1, and includes the following steps:

step S402, responding to the trigger condition of the intelligent insulator initialization completion, and broadcasting a networking request instruction; and the networking request instruction is used for instructing the concentrator to establish communication connection with the intelligent insulator.

The triggering condition may refer to a condition for representing that the intelligent insulator has completed initialization.

As an example, the intelligent insulator activates power-on and enters an initialization stage in response to an activation instruction, the intelligent insulator completes initialization in response to a trigger condition for completing initialization of the intelligent insulator, the intelligent insulator broadcasts a networking request instruction to the outside, and then enters a monitoring state.

Step S404, receiving the monitoring instruction sent by the concentrator under the condition that the target intelligent insulator is successfully communicated with the concentrator; the target intelligent insulators are all intelligent insulators in an intelligent insulator string to which the intelligent insulators belong.

As an example, after receiving a networking confirmation instruction sent by the concentrator, the intelligent insulator sends networking confirmation information to the concentrator, when the concentrator determines that the number of the intelligent insulators in communication connection with the concentrator meets a preset number requirement, the concentrator sends a monitoring instruction to the intelligent insulator, and the intelligent insulator receives the monitoring instruction sent by the concentrator and monitors the voltage of the power transmission line to be monitored.

Step S406, responding to the monitoring instruction, and performing voltage monitoring on the power transmission line to be detected according to a preset monitoring time interval to obtain voltage monitoring data; and the voltage monitoring data is used for the concentrator to determine a voltage measurement result corresponding to the power transmission line to be measured.

As an example, after receiving a monitoring instruction sent by the concentrator, the intelligent insulator monitors voltage data borne by the intelligent insulator according to a preset monitoring time interval, and uses the voltage data as voltage monitoring data corresponding to the power transmission line to be detected.

According to the technical scheme, after initialization of the intelligent insulator string is completed, a networking request instruction is broadcasted, after all intelligent insulators in the intelligent insulator string are in communication connection with the concentrator, the intelligent insulator timely monitors monitoring instructions sent by the concentrator, voltage monitoring is conducted on the power transmission line to be detected, voltage monitoring data are obtained, initialization of the intelligent insulator can be completed, and under the condition that the concentrator is in communication connection with all intelligent insulators in the intelligent insulator string, voltage monitoring is conducted on the power transmission line to be detected according to the monitoring instructions sent by the concentrator, the voltage monitoring data are obtained, the voltage monitoring data are sent to the concentrator to determine voltage measuring results corresponding to the power transmission line to be detected, voltages born by the intelligent insulators are respectively monitored, voltage monitoring data corresponding to the intelligent insulator string are timely obtained, the voltage measuring results corresponding to the power transmission line to be detected are further obtained, and therefore the measuring efficiency of the voltages in the power system is improved.

In some embodiments, the voltage monitoring of the power transmission line to be tested according to a preset monitoring time interval to obtain voltage monitoring data includes:

and acquiring a pre-calibrated proportionality coefficient corresponding to the intelligent insulator.

Wherein, the proportionality coefficient can mean the relation between the inside electric field intensity of intelligent insulator and the electric potential difference between intelligent insulator metal cap and the metal rod, and in practical application, the relation between the inside electric field intensity of intelligent insulator and the electric potential difference between intelligent insulator metal cap and the metal rod can be expressed by the following formula:

E _is ＝k _is U _is

wherein，E _is For the electric field strength, k, inside the intelligent insulator _is Is a proportionality coefficient, U _is The potential difference between the metal cap and the metal rod of the intelligent insulator is represented, and i is a serial number corresponding to the intelligent insulator.

As an example, as shown in fig. 5, when the intelligent insulator performs voltage monitoring, a potential difference U exists between the metal cap and the metal rod of the intelligent insulator _s The metal cap and the metal rod are filled with an insulating medium, the potential of the metal rod is larger than that of the metal cap at a certain moment, under the action of potential difference, electric field distribution exists in the insulating medium, electric field lines point to the metal cap from the metal rod, according to Maxwell's equations, the distribution of the electric field is related to the size of a field source and the distribution of a zero potential energy surface, the inner wall of the metal cap is regarded as the time zero potential energy surface, the metal rod is regarded as the field source, the electric field distribution is induced in the insulating medium, for a point with a fixed position, a direct ratio relation exists between the electric field intensity of the point and the potential difference, a voltage measuring module is arranged in the insulating medium, after the intelligent insulator is manufactured, the position of the voltage measuring module in the insulating medium is fixed, and the size of a proportionality coefficient is related to the position of an electric field sensitive chip in the intelligent insulator and the dielectric constant of the insulating medium, so that the proportionality coefficient can be obtained by experimental calibration calculation before the intelligent insulator leaves a factory; in the calibration process, an external excitation source is applied to the intelligent insulator, the electric field intensity of the electric field sensitive chip is obtained, and then the proportionality coefficient can be calculated.

And monitoring electric field intensity data corresponding to the intelligent insulator according to a preset monitoring time interval.

The electric field intensity data can refer to electric field intensity data measured by an electric field sensitive chip in a voltage measuring module of the intelligent insulator.

As an example, the intelligent insulator monitors the electric field strength data in the insulating medium at preset monitoring time intervals through an electric field sensitive chip in a voltage measurement module of the intelligent insulator in response to a monitoring instruction sent by the concentrator.

As an example, when voltage monitoring is performed on a power transmission line to be detected, a voltage difference between a metal cap and a metal rod of an intelligent insulator can be calculated through electric field intensity data of an electric field sensitive chip and a proportionality coefficient of the intelligent insulator, and the voltage difference is used as voltage monitoring data corresponding to the intelligent insulator; the relationship between the voltage difference between the metal cap and the metal rod of the intelligent insulator, the electric field intensity data measured by the electric field sensitive chip and the proportionality coefficient of the intelligent insulator can be expressed by the following formula:

U＝E/k

u is the potential difference between the metal cap and the metal rod of the intelligent insulator, E is the electric field intensity data inside the intelligent insulator, and k is the proportional coefficient corresponding to the intelligent insulator.

As an example, as shown in fig. 6, the metal rod of the last intelligent insulator in the intelligent insulator string is inserted into the metal cap of the next intelligent insulator, and the metal rod of the last intelligent insulator is in metal contact with the metal cap of the next intelligent insulator, so that the potential of the metal rod of the last intelligent insulator is equal to the potential of the metal cap of the next intelligent insulator, the metal cap of the first intelligent insulator in the intelligent insulator string is connected to the hardware of the line tower, so that the potential of the metal cap of the first intelligent insulator is 0, the metal rod of the last intelligent insulator in the intelligent insulator string is connected to the transmission line, so that the potential of the metal rod of the last intelligent insulator is consistent with the voltage of the transmission line to be measured, that is, the voltage of the transmission line to be measured is equal to the sum of the potential differences of the intelligent insulators in the intelligent insulator string, and therefore, the relationship between the voltage measurement result corresponding to the transmission line to be measured and the voltage monitoring data corresponding to the intelligent insulators in the intelligent insulator string can be expressed by the following formula:

wherein, U _ns Potential difference between metal cap and metal rod of nth intelligent insulator, E _ns Is the electric field intensity, k, inside the nth intelligent insulator _ns The scaling factor corresponding to the nth intelligent insulator is n =1,2,3, \8230;.

As an example, the relationship between the voltage measurement result of the transmission line under test and the voltage monitoring data of each intelligent insulator in the intelligent insulator string can be expressed by the following formula:
