Technical Field

[0001] This disclosure relates to the field of anti-icing and de-icing technology, and in particular to an anti-icing and de-icing treatment method, system, device, equipment and medium. Background Technology

[0002] In harsh environments such as low temperature, humidity, rain, snow, and frost, outdoor equipment such as wind turbine blades and power transmission lines are prone to icing, which can easily lead to operational safety hazards, equipment damage, and downtime.

[0003] In related technologies, the anti-icing and de-icing technology for outdoor equipment such as wind turbine blades and power transmission lines usually involves setting the anti-icing and de-icing current based on manual experience.

[0004] However, the above-mentioned method of relying on manual determination of the anti-icing current is difficult to achieve accurate anti-icing and de-icing, resulting in low anti-icing and de-icing efficiency. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this disclosure provides an anti-icing and de-icing treatment method, system, apparatus, equipment and medium.

[0006] In a first aspect, embodiments of this disclosure provide an anti-icing and de-icing method, comprising: Identify the object to be de-iced and obtain the current ice thickness of the object using an ice detection device; Obtain the current environmental information corresponding to the anti-icing object, including the ambient temperature, ambient wind speed, and ambient humidity of the environment where the anti-icing object is located; Based on the current ice thickness of the object to be de-iced and the current environmental information, an anti-icing mode and a corresponding anti-icing current are determined for the object to be de-iced. The anti-icing current is used to perform anti-icing treatment on the object to be de-iced.

[0007] In one optional implementation, determining the anti-icing mode and corresponding anti-icing current for the anti-icing object based on the current ice thickness and the current environmental information includes: If it is determined that the de-icing triggering condition is met based on the current ice thickness and the current environmental information, then the anti-de-icing object is controlled to enter the de-icing mode, and an optimal de-icing current is determined for the anti-de-icing object; the optimal de-icing current is the de-icing current that makes the current ice thickness of the anti-de-icing object no greater than the safe ice thickness and minimizes the de-icing energy consumption within a first preset time period. The de-icing triggering conditions include the current ice thickness not being less than the ice thickness threshold for de-icing activation, the ambient temperature not being greater than a first preset temperature threshold, the ambient wind speed not being less than a first preset wind speed threshold, and the ambient humidity not being less than a first preset humidity threshold. When the anti-icing object is in de-icing mode, the current ice thickness is obtained. If the current ice thickness is not greater than the de-icing stop ice thickness threshold, the anti-icing object is controlled to exit the de-icing mode. The de-icing stop ice thickness threshold is less than the de-icing start ice thickness threshold, and the de-icing stop ice thickness threshold is not greater than the safe ice thickness.

[0008] In one optional implementation, determining the anti-icing mode and corresponding anti-icing current for the anti-icing object based on the current ice thickness and the current environmental information includes: If it is determined that the anti-icing triggering condition is met based on the current ice thickness and the current environmental information, then the anti-icing object is controlled to enter the anti-icing mode, and an optimal anti-icing current is determined for the anti-icing object; the optimal anti-icing current is the anti-icing current that maintains the current ice thickness of the anti-icing object no longer increasing within a second preset time period, and minimizes the anti-icing energy consumption. The anti-icing triggering conditions include the current ice thickness not being greater than the anti-icing ice thickness threshold, the ambient temperature not being greater than the second preset temperature threshold, the ambient wind speed not being greater than the second preset wind speed threshold, and the ambient humidity not being less than the second preset humidity threshold; the anti-icing ice thickness threshold is less than the de-icing start ice thickness threshold, and the de-icing stop ice thickness threshold is not greater than the anti-icing ice thickness threshold.

[0009] In one optional implementation, after controlling the anti-icing object to exit the de-icing mode, the method further includes: Obtain the current environment information; If it is determined based on the current environmental information that the anti-icing object is at risk of re-icing, then after the anti-icing object exits the de-icing mode, it is controlled to enter the anti-icing mode, and an optimal anti-icing current is determined for the anti-icing object. The risk of re-icing is determined based on the ambient temperature, the ambient wind speed, and the ambient humidity.

[0010] In an optional implementation, after controlling the anti-icing object to enter anti-icing mode and determining the optimal anti-icing current for the anti-icing object, the method further includes: Obtain the current ice thickness and the current environmental information; If the current ice thickness increases to a level not less than the ice thickness threshold for triggering de-icing, or if the current ice thickness and the current environmental information determine that the de-icing trigger condition is met, then the anti-icing object is controlled to switch from anti-icing mode to de-icing mode. If the anti-icing exit conditions are determined based on the current environmental information, the anti-icing object is controlled to exit the anti-icing mode; wherein, the anti-icing exit conditions include at least one of the following: the ambient temperature is higher than a second preset temperature threshold, and the ambient humidity is lower than a second preset humidity threshold.

[0011] Secondly, embodiments of this disclosure provide an anti-icing and de-icing device, comprising: The first determining module is used to determine the object to be de-iced, and periodically obtains the current ice thickness of the object to be de-iced through the ice detection device; The first acquisition module is used to acquire the current environmental information corresponding to the anti-icing object, the current environmental information including the ambient temperature, ambient wind speed and ambient humidity of the environment where the anti-icing object is located; The second determining module is used to determine the anti-icing mode and the corresponding anti-icing current for the anti-icing object based on the current ice thickness of the anti-icing object and the current environmental information. The anti-icing current is used to perform anti-icing treatment on the anti-icing object.

[0012] Thirdly, this disclosure also provides an anti-icing and de-icing system, which includes a control device. The control device is used to determine an object to be de-iced, obtain the current ice thickness of the object through an ice detection device, obtain current environmental information corresponding to the object, including the ambient temperature, ambient wind speed, and ambient humidity of the environment where the object is located, and determine an anti-icing mode and a corresponding anti-icing current for the object based on the current ice thickness and the current environmental information. The anti-icing current is used to perform anti-icing and de-icing treatment on the object.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0022] In harsh environments such as low temperature, humidity, rain, snow, and frost, outdoor equipment such as wind turbine blades and power transmission lines are prone to icing, which can easily lead to operational safety hazards, equipment damage, and downtime.

[0023] In related technologies, the anti-icing and de-icing technology for outdoor equipment such as wind turbine blades and power transmission lines usually involves setting a fixed anti-icing and de-icing current based on manual experience.

[0024] However, the above-mentioned method of relying on manual determination of the anti-icing current is difficult to achieve accurate anti-icing and de-icing, resulting in low anti-icing and de-icing efficiency.

[0025] Based on the above embodiments, this disclosure provides a method for preventing and de-icing. The method will be described below with reference to specific embodiments.

[0026] Figure 1 This is a schematic flowchart illustrating an anti-icing and de-icing method according to an embodiment of this disclosure. This method can be applied to an anti-icing and de-icing system. The method can be implemented using software and / or hardware. Figure 1 As shown, the anti-icing and de-icing method includes: S101: Determine the object to be de-iced and obtain the current ice thickness of the object through the ice detection device.

[0027] Among them, the objects to be prevented from icing or de-iced are those that currently require icing prevention or de-icing. Specifically, the objects to be prevented from icing or de-iced can include outdoor facilities such as wind turbine blades and power transmission lines.

[0028] In this embodiment of the disclosure, the current ice thickness of the object to be de-iced refers to the thickness of the ice layer attached to the surface of the object in real time.

[0029] After identifying the object to be de-iced, the current ice thickness of the object can be collected by deploying an ice detection device. This information is used to determine the working mode of the object and the de-icing current. The details of the de-icing current will be described in later embodiments.

[0030] In one alternative implementation, the current ice thickness of the object to be de-iced can be collected in real time or at a preset cycle by deploying an ice detection device.

[0031] S102: Obtain the current environmental information corresponding to the anti-icing object, the current environmental information including the ambient temperature, ambient wind speed and ambient humidity of the environment where the anti-icing object is located.

[0032] The current environmental information can refer to the external environmental data of the object being de-iced, which is used to determine the de-icing current corresponding to the object being de-iced.

[0033] In one optional implementation, ambient temperature, ambient wind speed, and ambient humidity can be collected in real time or at preset intervals using a temperature sensor, a humidity sensor, and a wind speed sensor.

[0034] S103: Based on the current ice thickness of the object to be de-iced and the current environmental information, determine the de-icing mode and the corresponding de-icing current for the object to be de-iced. The de-icing current is used to perform de-icing treatment on the object to be de-iced.

[0035] In this embodiment of the disclosure, after obtaining the current ice thickness and current environmental information of the anti-icing / de-icing object, the operating mode of the anti-icing / de-icing object can be determined, and the corresponding optimal anti-icing current or optimal de-icing current can be determined after determining the operating mode. The operating modes of the anti-icing / de-icing object include a de-icing mode and an anti-icing mode, used to adapt to different icing conditions.

[0036] Anti-icing current refers to the working current applied to the object after matching the working mode. This current generates a thermal effect, which can suppress icing or melt existing ice layers on the object.

[0037] In one optional implementation, after obtaining the current ice thickness and current environmental information of the anti-icing object, it is determined whether the current ice thickness and current environmental information meet the de-icing triggering conditions. If the current ice thickness and current environmental information meet the de-icing triggering conditions, the anti-icing object is controlled to enter the de-icing mode, and the optimal de-icing current is determined for the anti-icing object.

[0038] The optimal de-icing current is the de-icing current that minimizes the current ice thickness of the object to be de-iced within a first preset time period while ensuring that the current ice thickness does not exceed the safe ice thickness and that the de-icing energy consumption is minimized. In other words, within the first preset time period, this optimal de-icing current can both ensure that the ice thickness of the object to be de-iced is reduced to within the safe ice thickness range and achieve the lowest possible de-icing energy consumption.

[0039] The first preset time period is a pre-set de-icing duration. Specifically, this first preset time period can be set according to the type of object to be de-iced. This first preset time period is used to limit the de-icing completion time and avoid prolonged ineffective de-icing. For example, the first preset time period is 1 hour.

[0040] The safe icing thickness is a preset ice layer thickness. This safe icing thickness is used to characterize the state of the object being de-iced or protected from frost, thin ice, and normal operation. In other words, this safe icing thickness is the maximum safe critical threshold, the maximum allowable icing thickness for the object being de-iced or protected from frost.

[0041] The de-icing triggering conditions may include ice thickness not less than the de-icing start ice thickness threshold, ambient temperature not greater than the first preset temperature threshold, ambient wind speed not less than the first preset wind speed threshold, and ambient humidity not less than the first preset humidity threshold.

[0042] The ice thickness threshold for de-icing activation is a pre-set ice thickness value based on the type of object to be de-iced. The first preset temperature threshold is a pre-set temperature value; the first preset wind speed threshold is a pre-set wind speed value; and the first preset humidity threshold is a pre-set humidity value.

[0043] Specifically, the ice thickness threshold, the first preset temperature threshold, the first preset wind speed threshold, and the first preset humidity threshold can be preset according to the results and materials of the object to be de-iced.

[0044] Among them, the first preset temperature threshold is the extremely low temperature threshold (e.g., -5℃ to 0℃) that triggers de-icing, the first preset wind speed threshold is the high wind speed threshold that easily accelerates icing, the first preset humidity threshold is the high humidity threshold that easily forms thick ice, and the de-icing start ice thickness threshold is the upper limit threshold of the ice layer thickness that needs to be activated for de-icing.

[0045] Based on the above embodiments, after the anti-icing object enters the de-icing mode, that is, after the anti-icing object meets the de-icing triggering conditions, the optimal de-icing current can be determined for the anti-icing object based on the current ice thickness and the current environmental information.

[0046] In one optional implementation, a correspondence table between ice thickness, ambient temperature, ambient wind speed, ambient humidity, and de-icing current is pre-established. The current ice thickness, ambient temperature, ambient wind speed, and ambient humidity are matched and compared with the correspondence table to obtain the corresponding candidate de-icing current. The correspondence table pre-stores the mapping relationships between ice thickness, ambient temperature, ambient wind speed, ambient humidity, and de-icing current.

[0047] Then, based on the thermal balance model, the ice thickness and de-icing energy consumption of each candidate de-icing current within the first preset time period are determined. Finally, from the candidate de-icing currents that satisfy the condition that the current ice thickness of the object within the first preset time period is not greater than the safe ice thickness, the candidate de-icing current with the lowest energy consumption is selected as the optimal de-icing current. The thermal balance model is used to characterize the thermal balance relationship between surface ice formation heat dissipation, current heating, and environmental heat transfer of the object being de-iced.

[0048] In another optional implementation, a preset de-icing current range is first obtained through simulation, taking into account the structure, material, surface icing characteristics, and environmental heat exchange conditions of the object to be de-iced. Any current value within this preset de-icing current range can be continuously output to remove the ice layer from the surface of the object.

[0049] Then, a simulation environment was built based on the current ice thickness of the object to be de-iced and the current environmental information. Within the preset de-icing current range, each candidate de-icing current was traversed, and the de-icing progress and de-icing energy consumption of each candidate de-icing current within a first preset time period were simulated. The de-icing progress is used to characterize the melting progress of the ice layer on the surface of the object to be de-iced and the remaining ice thickness after applying the candidate de-icing current within the first preset time period.

[0050] From the candidate de-icing currents, the candidate de-icing current with the remaining ice thickness corresponding to the de-icing progress not exceeding the safe ice thickness and the lowest de-icing energy consumption is selected, and this candidate de-icing current is taken as the optimal de-icing current.

[0051] In this embodiment of the disclosure, when the anti-icing object is in de-icing mode, the current ice thickness of the anti-icing object can be collected, and it can be detected whether the current ice thickness is not greater than the ice thickness threshold for stopping de-icing. Then, the anti-icing object is controlled to exit the de-icing mode.

[0052] The ice thickness threshold for stopping de-icing is less than the ice thickness threshold for starting de-icing, and the ice thickness threshold for stopping de-icing is not greater than the safe ice thickness.

[0053] In this embodiment, by setting the ice thickness threshold for stopping de-icing to be less than the ice thickness threshold for starting de-icing, a start-stop range for ice thickness is formed, which can avoid frequent start-stop of the de-icing mode due to small fluctuations in ice thickness. On the other hand, setting the ice thickness threshold for stopping de-icing to be no greater than the safe ice thickness can ensure that when the object to be de-iced exits the de-icing mode, its remaining ice thickness is within the safe ice thickness limit range, thus ensuring the structural safety and normal operation of the object to be de-iced.

[0054] The anti-icing and de-icing method provided in this embodiment includes: first, determining the object to be de-iced and obtaining the ice thickness of the object; then, obtaining current environmental information, including ambient temperature, ambient wind speed, and ambient humidity; and further, determining an anti-icing mode and a corresponding anti-icing current for the object based on the ice thickness and the current environmental information.

[0055] This embodiment of the invention obtains the ice thickness of the object to be de-iced, as well as the ambient temperature, humidity, and wind speed, to determine the working mode of the object and to determine the corresponding de-icing current under different working modes, so as to achieve precise de-icing for the object. Compared with the fixed current control method, it can adapt to different degrees of icing and environmental conditions, and further improve the de-icing efficiency for the object.

[0056] After controlling the anti-icing object to exit the de-icing mode, this embodiment of the present disclosure can also set a re-icing risk prediction mechanism. Specifically, after controlling the anti-icing object to exit the de-icing mode, the current environmental information collected is used to determine whether there is a risk of re-icing.

[0057] Specifically, if it is determined based on the current environmental information that the anti-icing object is at risk of re-icing, then after the anti-icing object exits the de-icing mode, the anti-icing object is controlled to enter the anti-icing mode, and the optimal anti-icing current is determined for the anti-icing object.

[0058] The optimal anti-icing current is the anti-icing current that, under anti-icing mode, can maintain the ice thickness of the object being de-iced within a second preset time period while minimizing anti-icing energy consumption. In other words, the optimal anti-icing current can continuously suppress ice formation on the surface of the object being de-iced within the second preset time period while minimizing anti-icing energy consumption.

[0059] The second preset time period is a pre-set anti-icing protection duration. This second preset time period can be the same as or different from the first preset time period. The risk of re-icing refers to the situation where, after the object being de-iced exits de-icing mode, the environmental conditions are deemed suitable for re-frost and icing based on current environmental information (ambient temperature, ambient wind speed, and ambient humidity). Specifically, the logic for determining the risk of re-icing can be as follows: if the currently collected ambient temperature is not greater than a second preset temperature threshold, the ambient humidity is not less than a second preset humidity threshold, and the ambient wind speed is within a reasonable range conducive to icing (e.g., not greater than a second preset wind speed threshold), then a risk of re-icing is determined, meaning the external environment still has the conditions for frost and icing. In this case, the object being de-iced is controlled to enter anti-icing mode, and an optimal anti-icing current is determined for it. If anti-icing protection is not implemented, the surface of the object may re-ice.

[0060] This embodiment of the invention obtains the ice thickness of the object to be de-iced, as well as the ambient temperature, humidity, and wind speed, to determine the working mode of the object and to determine the corresponding de-icing current under different working modes, so as to achieve precise de-icing for the object. Compared with the fixed current control method, it can adapt to different degrees of icing and environmental conditions, and further improve the de-icing efficiency for the object.

[0061] In one optional implementation, after obtaining the current ice thickness and current environmental information of the anti-icing object, it is determined whether the current ice thickness and current environmental information meet the anti-icing triggering conditions. If the current ice thickness and current environmental information meet the anti-icing triggering conditions, the anti-icing object is controlled to enter the anti-icing mode, and the optimal anti-icing current of the anti-icing object is determined.

[0062] The anti-icing triggering conditions may include the current ice thickness not exceeding the anti-icing ice thickness threshold, the ambient temperature not exceeding a second preset temperature threshold, the ambient wind speed not exceeding a first preset wind speed threshold, and the ambient humidity not exceeding a first preset humidity threshold. The anti-icing ice thickness threshold is less than the de-icing start ice thickness threshold, and the de-icing stop ice thickness threshold is not greater than the anti-icing ice thickness threshold.

[0063] The second preset temperature threshold is a pre-set temperature value, which is greater than the first preset temperature threshold. The second preset wind speed threshold is a pre-set wind speed value, and the second preset humidity threshold is a pre-set humidity value.

[0064] The second preset temperature threshold is the critical low temperature threshold for triggering anti-icing, specifically, for example, 0℃~3℃, which is greater than the first preset temperature threshold and is used to characterize the environmental temperature conditions that allow for frost formation and thin ice formation; the second preset wind speed threshold is a low wind speed threshold that makes it difficult for ice to thicken quickly; and the second preset humidity threshold is a high humidity threshold that makes it easy for thin ice and frost to form.

[0065] The anti-icing icing thickness threshold is the upper limit of the ice layer thickness when the anti-icing mode is activated. Its value is less than the ice thickness threshold when the de-icing mode is activated, and the ice thickness threshold when the de-icing mode is stopped is not greater than the anti-icing icing thickness threshold. This forms a gradient threshold range where the ice thickness threshold when the de-icing mode is stopped is the largest, the ice thickness threshold when the anti-icing mode is next, and the ice thickness threshold when the de-icing mode is activated is the smallest, thus achieving an orderly transition between the de-icing and anti-icing modes.

[0066] Based on the above embodiments, when the object to be de-iced is in anti-icing mode, the optimal anti-icing current can be determined for the object based on the current ice thickness and current environmental information. The method for determining the optimal anti-icing current can refer to the method for determining the optimal de-icing current, and will not be elaborated here.

[0067] After determining the optimal anti-icing current for the anti-icing object, this embodiment of the present disclosure can also detect whether it is necessary to switch the working mode of the anti-icing object by collecting the current ice thickness and current environmental information of the anti-icing object.

[0068] In one optional implementation, the current ice thickness and current environmental information of the anti-icing object during the anti-icing process are obtained, and it is detected whether the current ice thickness has increased to a level not less than the ice thickness threshold for starting the de-icing process. If the current ice thickness has increased to a level not less than the ice thickness threshold for starting the de-icing process, the anti-icing object is controlled to switch from the anti-icing mode to the de-icing mode.

[0069] In another optional implementation, the current ice thickness and current environmental information of the anti-icing object during the anti-icing process are obtained, and it is detected whether the current ice thickness and the current environmental information meet the de-icing triggering conditions. If the de-icing triggering conditions are met, the anti-icing object is controlled to switch from anti-icing mode to de-icing mode.

[0070] In another optional implementation, based on the obtained current ice thickness and the current environmental information, the current environmental information is detected to see if the anti-icing exit condition is met. If the anti-icing exit condition is met, the anti-icing object is controlled to exit the anti-icing mode.

[0071] The anti-icing exit condition includes at least one of the following: the ambient temperature is higher than a second preset temperature threshold, and the ambient humidity is lower than a second preset humidity threshold. When either condition is met, the anti-icing mode can be exited, and the application of anti-icing current can be stopped.

[0072] The embodiments disclosed herein employ a determination mechanism that allows the anti-icing mode to exit once any anti-icing exit condition is met. This mechanism can quickly identify when the environmental conditions improve and promptly exit the anti-icing mode and stop applying anti-icing current after the environmental conditions improve. This avoids continuous ineffective work under conditions without the risk of icing and effectively reduces the system's operating energy consumption.

[0073] In this embodiment, the ice thickness of the object to be de-iced, as well as the ambient temperature, humidity, and wind speed, are obtained. The operating mode of the object is determined, and the corresponding de-icing current is determined under different operating modes to achieve precise de-icing for the object. Compared with the fixed current control method, it can adapt to different degrees of icing and environmental conditions, and further improve the de-icing efficiency for the object.

[0074] Based on the above embodiments, this disclosure also provides an anti-icing and de-icing system, such as... Figure 2 The diagram shown is a structural schematic of an anti-icing and de-icing system provided in an embodiment of this disclosure. Assuming that the current anti-icing and de-icing target is a wind turbine blade, the pre-treatment operations for the wind turbine blade before the anti-icing and de-icing operation are not limited in this embodiment.

[0075] The anti-icing and de-icing system 201 includes a control device 202, a heating power supply 203, and an output module 204. The output current of the heating power supply can be adjusted by the control device.

[0076] The control device is used to determine the object to be de-iced (wind turbine blades) and to obtain the current ice thickness of the object to be de-iced through the ice detection device 205. After obtaining the current ice thickness of the object to be de-iced, the control device is also used to collect the current environmental information corresponding to the object by deploying an environmental monitoring device 206. The current environmental information includes the ambient temperature, ambient wind speed, and ambient humidity of the environment where the object is located. Specifically, the environmental monitoring device may include a temperature sensor, a humidity sensor, and a wind speed sensor.

[0077] In order to de-ice or prevent icing of an object, the control device is also used to determine the anti-icing mode and the corresponding anti-icing current for the object based on the current ice thickness of the object and the current environmental information. The anti-icing current is used to perform anti-icing treatment on the object.

[0078] After determining the anti-icing current for the object to be de-iced, the control device controls the output current of the heating power supply based on the anti-icing current.

[0079] Once the control device determines the anti-icing mode and corresponding anti-icing current (optimal anti-icing current or optimal de-icing current) of the object to be de-iced based on the current ice thickness and current environmental information, it will send a current adjustment command to the heating power supply. This command contains the target output current value (i.e., the determined anti-icing current value).

[0080] Then, after receiving the control command, the heating power supply adjusts its own output current to match the anti-icing current value issued by the control device, and applies the current stably to the anti-icing object through the output module.

[0081] During anti-icing and de-icing operation, the control device receives real-time environmental information from the environmental monitoring device and current ice thickness from the ice detection device. If it is determined that the anti-icing and de-icing current needs to be adjusted (e.g., the de-icing current needs to be reduced if the ice melts too quickly, or the anti-icing current needs to be adjusted due to changes in environmental conditions), a new current adjustment command is sent to the heating power supply in real time to control the output current of the heating power supply to adjust synchronously. This ensures that the anti-icing and de-icing current is always adapted to the current operating conditions, achieving optimal energy consumption while ensuring the anti-icing and de-icing effect, and improving the system's operational reliability and flexibility.

[0082] The anti-icing and de-icing system provided in this embodiment can determine the working mode of the object to be de-iced by acquiring the ice thickness, ambient temperature, ambient humidity and ambient wind speed, and determine the corresponding anti-icing and de-icing current in different working modes, so as to achieve precise anti-icing and de-icing for the object. Compared with the fixed current control method, it can adapt to different icing degrees and environmental conditions, and further improve the anti-icing and de-icing efficiency for the object.

[0083] Figure 3 This is a schematic diagram of an anti-icing and de-icing device provided in an embodiment of this disclosure. The device can be implemented by software and / or hardware, and can also be integrated into an electronic device. Figure 3 As shown, the anti-icing and de-icing device includes: The first determining module 301 is used to determine the object to be de-iced, and periodically obtains the current ice thickness of the object to be de-iced through the ice detection device; The first acquisition module 302 is used to acquire the current environmental information corresponding to the anti-icing object, the current environmental information including the ambient temperature, ambient wind speed and ambient humidity of the environment where the anti-icing object is located.
