[0083] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0084] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0085] my country has a vast territory and uneven energy distribution. Power transmission lines span large distances and are widely distributed, passing through high mountains, canyons, basins, plains and other areas with complex and varied topography and climate. Freezing and snow damage to power transmission lines occur frequently.

[0086] Using ice-observation equipment to monitor icing on power transmission lines is the most common method. This equipment is mounted on the conductor and extracts energy from the transmission line through induction. It typically consists of two sets of magnetic cores and coils: one for power extraction and the other for measurement. While offering relatively high energy extraction efficiency and current measurement accuracy, it also increases cost and weight. The added weight leads to greater installation difficulty and lower efficiency, thus impacting the deployment of ice-observation equipment to some extent.

[0087] To reduce the overall weight and size of the conductor ice observation equipment, the equipment can consist of only one power extraction coil. The measuring circuit and the power extraction circuit are alternately connected to the power extraction coil. However, when the power extraction coil is connected to the measuring circuit, the energy obtained from the transmission line cannot be effectively absorbed, resulting in energy waste. Especially when the current in the transmission line is low, the ice observation equipment may go offline due to insufficient energy extraction, affecting the operational reliability of the transmission line.

[0088] In view of this, this application provides a method for measuring the status information of transmission lines. When a first conduction trigger condition is met, the method controls the power-collecting coil and the power-collecting capacitor to conduct, thereby efficiently obtaining electrical energy from the transmission line and storing it in the power-collecting capacitor, ensuring continuous power acquisition and providing a stable power supply to the load. When a first measurement trigger condition is met, the method controls the measuring capacitor and the power-collecting coil to conduct, enabling the measuring capacitor to obtain electrical energy from the transmission line and simultaneously measure the status information of the transmission line. This not only allows for the acquisition of electrical energy but also enables real-time monitoring of the transmission line's status, providing crucial status information for system monitoring and maintenance. When a measurement termination condition is met, the system controls the measuring capacitor and the power-collecting capacitor to conduct, transferring the electrical energy from the measuring capacitor to the power-collecting capacitor. This reduces energy loss during transmission line status information measurement, optimizes energy utilization, avoids energy waste in the measuring capacitor, and improves the overall energy efficiency of the system.

[0089] Figure 1 An application scenario diagram provided for an embodiment of this application, such as... Figure 1As shown, the transmission line status information measurement system includes: a power-collecting coil, a power-collecting capacitor, a measuring capacitor, a control module, a first switch, a second switch, and a third switch. The transmission line passes through the power-collecting coil, which obtains electrical energy from the transmission line through induction. When a first conduction trigger condition is met, the control module controls the first switch to conduct, causing the power-collecting capacitor to conduct with the power-collecting coil. The electrical energy obtained by the power-collecting coil from the transmission line is transferred to the power-collecting capacitor, enabling the power-collecting capacitor to supply power to the load. When a first measurement trigger condition is met, the control module controls the second switch to conduct, causing the measuring capacitor to conduct with the power-collecting coil. The electrical energy obtained by the power-collecting coil from the transmission line is transferred to the measuring capacitor. The control module measures the status information of the transmission line through the measuring capacitor. When a measurement termination condition is met, the control module controls the third switch to conduct, causing the measuring capacitor to conduct with the power-collecting capacitor, transferring the electrical energy in the measuring capacitor to the power-collecting capacitor.

[0090] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0091] Figure 2 This is a flowchart illustrating a method for measuring the status information of a transmission line, provided in an embodiment of this application. The executing entity in this embodiment can be any device with data processing capabilities; however, this application uses a control module as the executing entity for specific description. Figure 2 As shown in the embodiment of this application, a method for measuring the status information of a transmission line may include:

[0092] Step 201: When the first conduction trigger condition is met, control the power-collecting capacitor and the power-collecting coil to conduct, wherein the power-collecting coil is used to obtain electrical energy from the transmission line and transmit it to the power-collecting capacitor, and the power-collecting capacitor is used to supply power to the load.

[0093] The transmission line passes through a power-collecting coil, which draws electrical energy from the transmission line through induction. Transmission line status information is used to indicate the state of the transmission line and may include: current information within the transmission line, such as the effective value of the current, maximum current value, average current value, and current waveform.

[0094] The first conduction trigger condition can be: receiving a measurement command, reaching a first preset time, or detecting that the measuring capacitor and the power-taking capacitor are disconnected. The first conduction trigger condition can be set as needed, and this application does not limit it.

[0095] Specifically, when the first conduction trigger condition is met, the control module controls the power-taking capacitor and the power-taking coil to conduct. The power-taking coil obtains electrical energy from the transmission line and transmits it to the power-taking capacitor, which is then used to supply power to the load.

[0096] Step 202: When the first measurement trigger condition is met, control the measuring capacitor to conduct with the power taking coil, obtain electrical energy from the transmission line through the measuring capacitor, and measure the status information of the transmission line.

[0097] The first measurement trigger condition can be: receiving a measurement command, reaching a second preset time, starting the timer from when the measuring capacitor and the power-taking capacitor are connected, after a first preset time, detecting that the power-taking capacitor and the power-taking coil are disconnected, etc. At this time, the power-taking capacitor has released all its energy, and the measuring capacitor is not connected to the power-taking coil. The first measurement trigger condition can be set as needed, and this application does not limit it.

[0098] Specifically, when the first measurement trigger condition is met, the control module controls the measuring capacitor to conduct with the power extraction coil, and the power extraction coil transmits the electrical energy obtained from the transmission line to the measuring capacitor, while the control module measures the status information of the transmission line.

[0099] Optionally, the status information includes a current value. When the first measurement trigger condition is met, the measuring capacitor is controlled to conduct with the power-taking coil, and electrical energy is obtained from the transmission line through the measuring capacitor. The status information of the transmission line is then measured, including:

[0100] When the first measurement trigger condition is met, the first initial voltage value between the two plates of the measurement capacitor is acquired.

[0101] The control capacitor is connected to the power-collecting coil to obtain electrical energy from the transmission line through the measuring capacitor;

[0102] When the second measurement trigger condition is met, the first current voltage value between the two plates of the measurement capacitor is collected;

[0103] The current value in the transmission line is determined based on the first initial voltage value and the first current voltage value.

[0104] The second trigger measurement condition can be that the timing starts from the moment the measuring capacitor and the power-taking coil are turned on, and after a preset time, or it can be that the voltage or rate of change between the two plates of the measuring capacitor meets a preset condition. This application does not limit this.

[0105] Specifically, the transmission line status information includes the current value in the transmission line. When the first measurement trigger condition is met, the control module acquires the first initial voltage value between the two plates of the measuring capacitor. After acquisition, the control module controls the measuring capacitor to conduct with the power extraction coil, and obtains electrical energy from the transmission line through the measuring capacitor. When the second measurement trigger condition is met, the control module acquires the first current voltage value between the two plates of the measuring capacitor. Based on the first initial voltage value and the first current voltage value, the current value in the transmission line is determined.

[0106] In this way, by collecting and measuring the initial and current voltage values ​​between the two plates of the capacitor under specific conditions, the current value in the transmission line can be accurately calculated, providing high-precision current measurement and improving the accuracy of current measurement in the transmission line.

[0107] Optionally, determining the current value in the transmission line based on the first initial voltage value and the first current voltage value includes:

[0108] Based on the first initial voltage value and the first current voltage value, determine the first energy harvesting power corresponding to the measuring capacitor;

[0109] The current value in the transmission line is determined based on the first energy extraction power and the pre-stored calibration coefficient, wherein the calibration coefficient is used to indicate the relationship between the first energy extraction power and the current value.

[0110] The calibration coefficients can be pre-stored in the control module or pre-stored at a preset address outside the control module. The control module obtains the calibration coefficients from the preset address. This application does not limit this. The calibration coefficients can be used to indicate the relationship between the first energy harvesting power and the current value.

[0111] Specifically, the control module determines the first energy harvesting power corresponding to the measuring capacitor based on the first initial voltage value and the first current voltage value collected, and determines the current value of the transmission line based on the first energy harvesting power and the pre-stored calibration coefficient.

[0112] In this way, by calculating and measuring the energy harvesting power of the capacitor and using the pre-stored calibration coefficients to determine the current value, the accuracy of current measurement can be further improved. Furthermore, using the pre-stored calibration coefficients to indicate the relationship between the energy harvesting power and the current value can simplify the current calculation process and improve the efficiency of current calculation. By pre-calibrating the coefficients under different operating conditions, the accuracy and consistency of the measurement can be improved.

[0113] Optionally, determining the first energy harvesting power corresponding to the measuring capacitor based on the first initial voltage value and the first current voltage value includes:

[0114] The first energy harvesting power corresponding to the measuring capacitor is calculated according to the following formula:

[0115]

[0116] Wherein, W represents the first power harvesting, C represents the capacitance of the measuring capacitor, U represents the first current voltage value, and U0 represents the first initial voltage value.

[0117] In this way, the accuracy and efficiency of calculating the first harvested power can be improved through the above formula, which makes it easier to quickly obtain the first harvested power in practical applications while ensuring the accuracy of the calculation results.

[0118] Optionally, the transmission line status information measurement method provided in this application further includes:

[0119] When the calibration trigger condition is met, the following coefficient determination operation is repeated until the calibration coefficient is obtained. When the calibration trigger condition is met, the current source outputs a current with a preset value in the simulated conductor passing through the power taking coil. The simulated conductor is used to simulate a power transmission line. The current in the power transmission line comes from the output of the power generation equipment. The current source is used to simulate the power generation equipment to output current in the simulated current.

[0120] Accordingly, based on the first energy extraction power and the pre-stored calibration coefficients, the current value in the transmission line is determined, including:

[0121] Divide the first energy harvesting power by the calibration coefficient to obtain the current value in the transmission line;

[0122] The coefficient determination operation includes:

[0123] Acquire the second initial voltage value between the two plates of the measuring capacitor;

[0124] Control the measurement capacitor to conduct with the power-taking coil;

[0125] When the second measurement trigger condition is met, the second current voltage value between the two plates of the measuring capacitor is acquired, and the measuring capacitor is disconnected from the power-taking coil.

[0126] Based on the second initial voltage value and the second current voltage value, determine the second energy harvesting power corresponding to the measuring capacitor;

[0127] When the ratio of the second energy harvesting power to the preset value is within a preset range, the ratio is determined to be the calibration coefficient;

[0128] When the ratio of the second energy harvesting power to the preset value is not within the preset range, it is determined that the ratio is not the calibration coefficient.

[0129] The calibration trigger condition can be when a calibration command is received.

[0130] Specifically, a simulated conductor is passed through a power-collecting coil, and a current source is connected to both ends of the simulated conductor to output a current with a preset value in the simulated conductor. The simulated conductor is used to simulate a power transmission line in a real working scenario, and the current source is used to simulate a power generation device in a real working scenario. The output of the power generation device is the source of the current in the power transmission line.

[0131] When the calibration triggering conditions are met, the current source outputs a current with a preset value in the simulated wire passing through the power take-off coil. The control module repeatedly performs the following coefficient determination operation until the calibration coefficient is obtained.

[0132] After obtaining the calibration coefficients, the simulated conductor is removed from the power extraction coil, and the transmission line is passed through the power extraction coil to enter the actual working scenario. In the actual working scenario, the current value in the transmission line is determined based on the first power extraction power and the pre-stored calibration coefficients, including: dividing the first power extraction power by the calibration coefficients to obtain the current value in the transmission line.

[0133] The coefficient determination operation includes: the control module acquires the second initial voltage value U1 between the two plates of the measuring capacitor; then, the control module controls the measuring capacitor to conduct with the power-taking coil; when the second measurement trigger condition is met, the control module acquires the second current voltage value U2 between the two plates of the measuring capacitor; after acquiring the second current voltage value, the control module controls the measuring capacitor to disconnect from the power-taking coil; the control module uses the formula... Determine the second energy harvesting power and the second energy harvesting power corresponding to the measuring capacitor; when the ratio of the second energy harvesting power to the preset value is within the preset range, determine the ratio as a calibration coefficient; when the ratio of the second energy harvesting power to the preset value is not within the preset range, determine that the ratio is not a calibration coefficient.

[0134] Furthermore, in the simulated working environment, if the moment when the control measuring capacitor and the power-taking coil are turned on is the first moment, and the moment when the second current voltage value is collected is the second moment, the difference between the second moment and the first moment should be the same as the corresponding difference in the real working scenario. The corresponding difference in the real working scenario is the difference between the third moment and the fourth moment. The third moment is the moment when the control measuring capacitor and the power-taking coil are turned on in the real working scenario, and the fourth moment is the moment when the first current voltage value between the two plates of the measuring capacitor is collected.

[0135] In this way, when the calibration triggering conditions are met, the system repeatedly performs the coefficient determination operation until accurate calibration coefficients are obtained. This repeated operation ensures the accuracy of the calibration coefficients, thereby improving the accuracy of subsequent current value calculations. Furthermore, by using simulated conductors and current sources to simulate the output current of transmission lines and generating equipment, this design can simulate real transmission line conditions in a laboratory environment, thereby enabling accurate calibration and testing and reducing the complexity and cost of calibration in a real-world environment.

[0136] Step 203: When the measurement end condition is met, control the measuring capacitor and the power taking capacitor to conduct, so as to transfer the electrical energy of the measuring capacitor to the power taking capacitor.

[0137] The measurement termination condition can be either detecting that the measuring capacitor is disconnected from the power-taking coil, or starting the timer from the disconnection of the measuring capacitor and the power-taking coil and allowing for a preset duration. This can be set according to actual needs, and this application does not limit it.

[0138] Specifically, when the measurement termination condition is met, the control module controls the measuring capacitor and the power-taking capacitor to conduct, so as to transfer the electrical energy of the measuring capacitor to the power-taking capacitor, and the capacitance of the measuring capacitor should be less than the capacitance of the power-taking capacitor.

[0139] Optionally, this application provides a method for measuring the status information of transmission lines, which further includes: controlling the measuring capacitor to disconnect from the power taking capacitor when the power transfer termination condition is met.

[0140] The power transfer termination condition can be set according to actual needs, and this application does not limit it. For example, the power transfer termination condition is: starting from the time the measuring capacitor and the power taking capacitor are turned on, after a preset time, the measuring capacitor and the power taking coil are in a disconnected state.

[0141] Specifically, when the power transfer termination condition is met, the control module controls the measuring capacitor to disconnect from the power taking capacitor.

[0142] In this way, disconnection is only performed when specific conditions are met. This precise control ensures the integrity and accuracy of the power transfer process and avoids energy loss caused by disconnection too early or too late.

[0143] The transmission line status information measurement method provided in this application controls the power-collecting coil and the power-collecting capacitor to conduct when the first conduction trigger condition is met, thereby efficiently obtaining electrical energy from the transmission line and storing it in the power-collecting capacitor, ensuring continuous power acquisition and providing a stable power supply to the load.

When the measurement termination condition is met, the system controls the measuring capacitor and the power-collecting capacitor to conduct, transferring the electrical energy in the measuring capacitor to the power-collecting capacitor. This reduces energy loss during transmission line status information measurement, optimizes energy utilization, avoids energy waste in the measuring capacitor, and improves the overall energy efficiency of the system.

The protection module includes three stages of energy discharge: the first stage is discharge via a gas discharge tube, the second stage is discharge via a varistor, and the third stage is discharge via a TVS diode. The protection module is connected to a rectifier and filter module, which filters and rectifies the current. The rectifier and filter module is connected to a capacitor switching switch, which includes two switches: one connected to the power-taking capacitor and the other connected to the measuring capacitor. The two control switches are controlled by a control module and are interlocked. When power is taken, the power-taking capacitor is connected; when measuring, the measuring capacitor is connected.

[0190] Figure 9 A flowchart illustrating another method for measuring transmission line status information provided in this application embodiment is shown below. Figure 9 As shown, the standard current source outputs a set current value in the simulated conductor. The MCU receives a control command and determines whether the command is a calibration command. If the received command is a calibration command, the MCU acquires and calculates the second initial voltage value U1 corresponding to the measuring capacitor, disconnects the power supply control switch, and closes the measurement control switch. After a preset time, the MCU acquires and calculates the second current voltage value U2 corresponding to the measuring capacitor. The MCU then calculates the current voltage value U2 according to the formula... Calculate the second energy harvesting power W1, where C represents the capacitance of the measuring capacitor; the ratio of the second energy harvesting power W1 to the set current value is the calibration coefficient; when the value of the calibration coefficient is within the set range, the calibration is successful and the calibration coefficient is stored.

[0191] When the MCU receives a power-down command, it controls the power-down control switch to turn on, allowing the power-down capacitor to store energy and supply energy to the load. The following steps are repeated: After the MCU controls the power-down control switch to turn on, and after time interval 1, it acquires and calculates the first initial voltage value U0 corresponding to the capacitor. Then, the MCU controls the power-down control switch to turn off and controls the measurement control switch to turn on. After time interval 2, it acquires and calculates the first current voltage value U corresponding to the capacitor. Then, the MCU controls the measurement control switch to turn off and controls the power-down control switch to close. Afterwards, it controls the energy release switch to turn on. After time interval 3, the energy in the capacitor is completely released, and the MCU controls the energy release switch to turn off. The MCU then executes the following steps according to the formula: The first energy harvesting power W is calculated, and the first energy harvesting power W is divided by the calibration coefficient to calculate the current value in the transmission line. The value is stored locally and transmitted to the core board via 485 to the control center.
