[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] Figure 1 The module connection diagram of the voltage regulating device with ice melting function in the embodiment of the present invention is shown. The voltage regulating device includes: a main control unit 10, a voltage regulating component 20, a voltage regulating and variable resistance component, and a detection and identification unit 30. The detection and identification unit 30 includes an icing sensor 31 and a vibration sensor 32. Based on the main control unit 10, the voltage regulating component 20 and the voltage regulating and variable resistance component are automatically regulated to realize the adjustment of the voltage regulating output of the voltage regulating device, so that the voltage regulating device can meet the cable ice melting requirements.

[0036] The voltage regulating component 20 is provided with a selection switch and several groups of coils. The connection contact of the selection switch is connected to one group of the several groups of coils. The voltage regulating and variable resistance component is provided with several voltage regulators, and the several voltage regulators are connected to the several groups of coils in one-to-one correspondence.

[0037] Further, the connection contact of the selection switch can be configured as silver tungsten alloy, and the contact resistance of the silver tungsten alloy is less than 5 μΩ, which can ensure the smoothness of the connection switching state between the selection switch and the coil.

[0038] The main control unit 10 is signal-connected to the detection and identification unit 30, and the main control unit 10 generates an ice melting voltage regulating instruction for controlling the voltage regulating component 20 based on the icing sensor 31 of the detection and identification unit 30;

[0039] The main control unit 10 generates a real-time adjustment instruction for driving the voltage regulating and variable resistance component to work based on the vibration sensor 32 of the detection and identification unit 30.

[0040] Specifically, the main control component is provided with a first data processing unit 21 and a second data processing unit 22. Based on the first data processing unit 21 and the second data processing unit 22, the detection data obtained by the detection and identification unit 30 can be processed, so that the main control component can make an immediate and accurate control adjustment reaction according to the detection data.

[0041] The first data processing unit 21 is used to obtain the icing detection information of the icing sensor 31, generate an ice melting voltage regulating instruction according to the icing detection information, and obtain the icing condition of the cable and the position distribution of the cable icing based on the icing detection information.

[0042] Extract the icing condition of the cable based on the icing detection information, obtain the icing position distribution of the cable within the operating range of the voltage regulating device, and adjust the voltage regulation operation of the voltage regulating device according to the icing thickness at each icing position.

[0043] Specifically, the icing sensor 31 can be configured as a microwave sensor to detect the icing condition on the cable. By sending microwaves to the icing position of the cable and based on the difference in the propagation rate of microwaves in different media (such as water, ice, and air), the icing position and icing thickness on the cable can be obtained according to the feedback information of the microwaves.

[0044] Specifically, the first data processing unit 21 obtains the icing distribution position and icing thickness data of the cable according to the icing data, selects the de-icing target position based on the icing distribution position and the icing thickness data, and sets the first de-icing control instruction according to the icing data at the de-icing target position.

[0045] Based on the icing sensor 31, a number of icing positions on the cable are obtained, and the spacing data between each icing position is obtained according to the distribution of the number of icing positions.

[0046] Based on the icing sensor 31, the icing thickness of a number of icing positions on the cable is obtained, and the average icing thickness of the icing positions on the cable is obtained by calculating the mean value according to the magnitudes of the icing thicknesses of the number of icing positions.

[0047] Further, the icing positions with icing thickness data greater than the average icing thickness are marked. Combining the spacing data between each icing position, a de-icing target position is selected from the number of icing positions, and the voltage regulation control calculation of the voltage regulation component 20 is performed based on the icing data at the de-icing target position.

[0048] Specifically, for each icing position among the number of icing positions, the spacing data is calculated. The first spacing value between the current icing position and the previous icing position is obtained, and the second spacing value between the current icing position and the next icing position is obtained. The spacing calculation value of the current icing position is calculated based on the first spacing value and the second spacing value.

[0049] Further, according to the distribution arrangement order of the number of icing positions, the spacing between the icing position at the first place and the adjacent next icing position is used as the spacing calculation value of the icing position at the first place; the spacing between the icing position at the last place and the adjacent previous icing position is used as the spacing calculation value of the icing position at the last place.

[0050] Specifically, by integrating the icing thickness data and icing position data of several icing positions, select the icing position with the smallest calculated value of the corresponding spacing of the icing positions and with the icing thickness data of the icing position greater than the average icing thickness as the ice melting target position, and obtain the icing thickness data of the ice melting target position.

[0051] The second data processing unit 22 is configured to obtain the detected vibration data of the vibration sensor 32, generate a real-time adjustment instruction according to the detected vibration data, and based on the detected vibration data obtained by the vibration sensor 32, enable the voltage regulating device to adjust the voltage regulating output state according to the vibration condition under the cable ice melting state, so as to meet the cable ice melting requirements.

[0052] Further, during the cable ice melting process, based on the icing position of the cable, in the case of ice blocks melting and falling off, since the position where the main body of the ice block contacts the cable is heated by the current transmitted by the cable, the contact position between the ice block and the cable is prone to melting, making the ice block prone to falling off as a whole. During the process of the ice block falling off, it causes a vibration impact on the cable and interferes with the stability of the current transmission of the cable. Moreover, between multiple icing areas of the cable, based on the vibration impact of the ice block falling, it drives the vibration and falling of the remaining icing positions. Based on the voltage regulating and variable resistance component, the output voltage of the voltage regulating component 20 can be adjusted, enabling the current value of the cable to be adaptively adjusted, reducing the heating temperature of the cable, and improving the safety of the cable current transmission.

[0053] Specifically, during the cable ice melting operation, based on the vibration sensor 32, the vibration data of the cable is obtained in real time, and the real-time vibration data of each sampling is compared and calculated with the initial vibration data to obtain the vibration change amplitude of the cable, so that the voltage regulating component 20 adjusts the working resistance value of the voltage regulating and variable resistance component based on the vibration change amplitude of the cable, realizing the real-time adjustment of the voltage regulation control of the cable.

[0054] Further, the calculation formula for the vibration change amplitude is:

[0055] f′ = (f1 - f0) / f0;

[0056] Where f′ is the vibration change amplitude, f1 is the real-time vibration data, and f0 is the initial vibration data.

[0057] Further, the vibration change amplitude is compared with the vibration amplitude standard value preset by the main control unit of the voltage regulating device. If the vibration change amplitude is greater than the vibration amplitude standard value, the resistance value of the voltage regulating and variable resistance component is adjusted.

[0058] Further, the working resistance value of the voltage regulating and variable resistance component is calculated in combination with the vibration change amplitude and the vibration amplitude standard value for adjustment. The calculation formula for the working resistance value adjustment of the voltage regulating and variable resistance component is as follows:

[0059] R ′ = R0 * (1 + μ);

[0060] μ = (f′ - fs) / fs;

[0061] Wherein, R ′ is the working resistance value adjustment of the voltage regulating and variable resistance component, R0 is the working resistance value of the voltage regulating and variable resistance component, f′ is the vibration change amplitude, fs is the vibration amplitude standard value, and μ is the coefficient.

[0062] Further, according to the vibration condition of the cable during the ice melting process, the working resistance value of the voltage regulating and variable resistance component is adjusted, so that the output voltage of the voltage regulating device can be adjusted according to the vibration condition of the cable, which can effectively adjust the heating condition of the current in the cable, thereby adjusting the ice melting rate of the cable, enabling the cable to melt ice smoothly, reducing the vibration amplitude of the cable, and improving the safety of cable ice melting.

[0063] Specifically, the voltage regulating and variable resistance component is connected in series to the circuit where the output end of the voltage regulating component 20 is located, so that the voltage regulating and variable resistance component can adjust the output voltage of the voltage regulating component 20, thereby increasing the floating change of the current transmitted by the cable, so that the cable can perform ice melting operation based on the working heat of the transmitted current.

[0064] Further, by adjusting the resistance value of the voltage regulating and variable resistance component connected to the circuit, the voltage regulating and variable resistance component can adjust the working voltage value of the voltage regulating component 20, thereby improving the control of the magnitude of the current output by the voltage regulating component 20 to the cable, so that the magnitude of the current value in the cable can meet the ice melting function requirements of the cable.

[0065] Further, the voltage regulating resistor can be configured as a sliding resistor. By setting the brush to move on the slide rail, the resistance value of the voltage regulating resistor connected to the circuit is changed, thereby realizing the voltage adjustment of the voltage regulating component 20.

[0066] The embodiment of the present invention provides a voltage regulating device with an ice melting function. By connecting a voltage regulating and variable resistance component in series to the output end circuit of the voltage regulating component 20 of the voltage regulating device, and cooperating with the vibration sensor 32 to obtain the vibration condition of the cable during the ice melting process, the voltage regulating device can perform real-time adjustment of the working voltage of the cable during the ice melting process of the cable, reduce the risk of overheating of the cable, and improve the ice melting efficiency and stability of the cable through real-time voltage regulation control during the ice melting process of the cable.

[0069] S11: Obtain the icing data of the cable based on the icing sensor, and generate a first ice melting control instruction according to the icing data.

[0070] Obtain the icing data of the cable based on the icing sensor. The icing data includes the icing position and icing thickness of the cable. The icing sensor can be configured as a microwave sensor. Based on the icing sensor, detect the icing condition on the cable. By sending microwaves to the icing position of the cable, according to the propagation rate differences of microwaves in different media (such as water, ice, and air), and according to the feedback information of the microwaves, obtain the icing position and icing thickness conditions on the cable.

[0071] Specifically, the obtaining the icing data of the cable based on the icing sensor and generating a first ice melting control instruction according to the icing data includes:

[0072] Obtain the icing distribution position and icing thickness data of the cable according to the icing data, select the ice melting target position based on the icing distribution position and the icing thickness data, and set the first ice melting control instruction according to the icing data of the ice melting target position.

[0073] Obtain several icing positions on the cable based on the icing sensor, and obtain the spacing data between each icing position according to the distribution condition of the several icing positions.

[0074] Obtain the icing thickness of several icing positions on the cable based on the icing sensor, and perform an average value calculation according to the icing thickness magnitudes of the several icing positions to obtain the average icing thickness of the icing positions on the cable.

[0075] Specifically, the icing sensor can be configured as a microwave sensor. Based on the icing sensor, detect the icing condition on the cable. By sending microwaves to the icing position of the cable, according to the propagation rate differences of microwaves in different media (such as water, ice, and air), and according to the feedback information of the microwaves, obtain the icing position and icing thickness conditions on the cable.

[0076] Further, mark the icing positions where the icing thickness data is greater than the average icing thickness, combine the spacing data between each icing position, select an ice melting target position from the several icing positions, and perform voltage regulation control calculation of the voltage regulation component based on the icing data of the ice melting target position.

[0077] Specifically, for each icing position among several icing positions, calculate the spacing data, obtain the first spacing value between the current icing position and the previous icing position, obtain the second spacing value between the current icing position and the next icing position, and calculate the spacing calculation value of the current icing position based on the first spacing value and the second spacing value.

[0078] Further, according to the arrangement order of the distribution of several icing positions, the spacing between the icing position at the first place and the adjacent next icing position is used as the spacing calculation value of the icing position at the first place; the spacing between the icing position at the last place and the adjacent previous icing position is used as the spacing calculation value of the icing position at the last place.

[0079] Specifically, by integrating the icing thickness data and the icing position data of several icing positions, select the icing position with the smallest corresponding spacing calculation value and the icing thickness data of the icing position greater than the average icing thickness as the ice melting target position, and obtain the icing thickness data of the ice melting target position.

[0080] S12: Execute the first ice melting control instruction, and obtain the vibration data of the cable ice melting state based on the vibration sensor.

[0081] Specifically, based on the vibration sensor to detect the vibration data of the cable during the ice melting process, adjust the voltage regulating component according to the first ice melting control instruction, and select the corresponding output voltage value according to the icing thickness of the ice melting target position, so that the current value in the cable can meet the ice melting requirement of the ice melting target position.

[0082] During the ice melting process of the cable based on the icing position of the cable, in the case of ice blocks melting and falling off, since the position where the main body of the ice block contacts the cable is heated by the current transmitted by the cable, the contact position between the ice block and the cable is prone to melting, making the ice block prone to falling off as a whole. During the process of the ice block falling off, it causes a vibration impact on the cable, interfering with the stability of the current transmission of the cable. Moreover, between multiple icing areas of the cable, based on the vibration impact of the ice block falling, it drives the vibration and falling of the remaining icing positions. Based on the voltage regulating and variable resistance component, the output voltage of the voltage regulating component can be adjusted, so that the current value of the cable is adaptively adjusted, reducing the heating temperature of the cable and improving the safety of the cable current transmission.

[0083] Before executing the first ice melting control instruction, based on the vibration sensor to detect the vibration state of the cable, obtain the initial vibration data of the cable, perform the ice melting operation on the cable based on the first ice melting control instruction, and based on the vibration sensor to continuously detect the vibration data of the cable during the ice melting process, so as to adjust the voltage regulating work of the voltage regulating component according to the vibration data.

[0084] Specifically, based on the initial vibration data collection of the cable by the vibration sensor, a vibration sensor is installed on the cable, and the vibration sensor is calibrated. By calibrating the sensor sensitivity, the environmental noise interference is reduced. Before the ice melting operation, ensure that the vibration sensor installation position covers the cable ice-prone section, and accurately obtain the vibration data of the cable before ice melting based on the vibration sensor.

[0085] Furthermore, during the cable melting process, the vibration condition of the cable is obtained based on the vibration sensor. If the vibration amplitude of the cable increases suddenly, it may indicate that the ice layer of the ice-covered section of the cable is broken or falling off. If the vibration frequency of the cable changes, such as high-frequency vibration, it can be indicated that the ice in the ice-covered section of the cable is cracked, such as low-frequency swinging may be caused by cable instability. The cable melting status can be obtained based on the data fed back by the vibration sensor, so as to perform voltage regulation control and improve the stability of cable melting.

[0086] S13: Generate a real-time adjustment instruction according to the vibration data, and adjust the working resistance value of the voltage regulating variable resistance component based on the real-time adjustment instruction.

[0087] Specifically, during the ice-melting operation of the cable, the vibration data of the cable is obtained in real time based on the vibration sensor, and the real-time vibration data sampled each time is compared and calculated with the initial vibration data to obtain the vibration change amplitude of the cable, so that the voltage regulating component can adjust the working resistance of the voltage regulating variable resistance component based on the vibration change amplitude of the cable, thereby realizing real-time adjustment of the voltage regulating control of the cable.

[0088] Furthermore, the vibration variation amplitude calculation formula is:

[0089] f′=(f1-f0) / f0;

[0090] Among them, f′ is the vibration change amplitude, f1 is the real-time vibration data, and f0 is the initial vibration data.

[0091] Furthermore, the vibration variation amplitude is compared with a vibration amplitude standard value preset by a main control unit of the voltage regulating device. If the vibration variation amplitude is greater than the vibration amplitude standard value, the resistance value of the voltage regulating variable resistance component is adjusted.

[0092] Furthermore, the working resistance of the voltage-regulating variable resistance component is calculated and adjusted in combination with the vibration change amplitude and the vibration amplitude standard value. The working resistance adjustment value calculation formula of the voltage-regulating variable resistance component is:

[0093] R ′ =R0*(1+μ);

[0094] μ=(f ′ -fs) / fs;

[0095] Among them, R′ is the adjusted value of the working resistance of the voltage regulating and variable resistance component, R0 is the working resistance of the voltage regulating and variable resistance component, f′ is the vibration change amplitude, fs is the standard value of the vibration amplitude, and μ is a coefficient.

[0096] Furthermore, according to the vibration condition of the cable during the ice melting process, the working resistance of the voltage regulating and variable resistance component is adjusted, so that the output voltage of the voltage regulating device can be adjusted according to the vibration condition of the cable, the heating condition of the current in the cable can be effectively adjusted, thereby adjusting the ice melting rate of the cable, enabling the cable to melt ice smoothly, reducing the vibration amplitude of the cable, and improving the safety of cable ice melting.

[0097] Specifically, during the ice melting operation of the cable, based on the vibration sensor, the vibration data of the cable is obtained in real time, and the vibration change amplitude of the cable is obtained by comparing and calculating the real-time vibration data of each sampling with the initial vibration data, so that the voltage regulating component adjusts the working resistance of the voltage regulating and variable resistance component based on the vibration change amplitude of the cable, realizing the real-time adjustment of the voltage regulation control of the cable.

[0098] Specifically, the voltage regulating and variable resistance component is connected in series to the circuit where the output end of the voltage regulating component is located, so that the voltage regulating and variable resistance component can adjust the output voltage of the voltage regulating component, thereby increasing the floating change of the current transmitted by the cable, so that the cable can perform ice melting operation based on the working heat of the transmitted current.

[0099] Furthermore, by adjusting the resistance value of the voltage regulating and variable resistance component connected to the circuit, the voltage regulating and variable resistance component can adjust the working voltage value of the voltage regulating component, thereby increasing the control of the magnitude of the current output by the voltage regulating component to the cable, so that the magnitude of the current value in the cable can meet the functional requirements of cable ice melting.

[0100] Furthermore, the voltage regulating resistor can be configured as a sliding resistor. By setting the brush to move on the slide rail, the resistance value of the voltage regulating resistor connected to the circuit is changed, thereby realizing the voltage adjustment of the voltage regulating component.

[0101] The embodiment of the present invention provides a control method for a voltage regulating device with an ice melting function. By setting an ice formation sensor and a vibration sensor, a first ice melting control instruction is set according to the ice formation position of the cable, and the cable is melted according to the first ice melting control instruction. During the ice melting process, the working state of the voltage regulating and variable resistance component is adjusted through the vibration sensor, realizing the adjustment of the output voltage of the voltage regulating component, thereby enabling the real-time adjustment of the ice melting current of the cable during the cable ice melting process, being able to adjust the working state of the voltage regulating component in real time during the ice melting process, so that the voltage regulating component can accurately adjust the ice melting of the cable, improving the cable ice melting efficiency, being able to control the vibration frequency during the cable ice melting process, and effectively improving the safety of cable ice melting.
