In the whole descaling process, the equipment to be descaled does not need to stop running, and descaling treatment is completed under the condition that the equipment to be descaled normally works.
In one embodiment, as shown in fig. 4, step S304 includes:
s402, the lower limit frequency of the resonance frequency range of the dirt is set as the target vibration frequency. In this embodiment, the lower limit frequency F of the resonance frequency range is setminThe target vibration frequency is used as the initial target vibration frequency, namely the target vibration frequency which is required to be reached by the vibration of the whole machine when the equipment to be descaled is applied with the vibration signal for the first time.
And S404, obtaining a vibration adjusting frequency according to the initial vibration frequency and the target vibration frequency.
Assume an initial vibration signal of x0The target vibration signal is xtTo change the vibration frequency of the apparatus to be descaled from the initial vibration frequency to the target vibration frequency, a vibration signal x is appliedsSo as to satisfy the following conditions:

And S408, when the vibration signal updating condition is met, updating the target vibration frequency according to the updating rule, and returning to the step S404 until the descaling ending condition is met.
The update rule is used for updating the target vibration frequency according to a certain rule, so that the updated target vibration frequency is different from the target vibration frequency before updating, and the updated target vibration frequency is within the resonance frequency range. Specifically, the update rule may be to increase a preset frequency value, and the preset frequency value may be configured as needed. For example, if the preset frequency value is 1, the update rule can be expressed as: ft=Ft+1. In other embodiments, the update rule may also be to increase the target vibration frequency proportionally, and the like, and the specific update rule may be set according to requirements.
Specifically, whether a vibration signal updating condition is met or not is judged, if yes, the target vibration frequency is updated according to an updating rule, the step of obtaining the vibration adjusting frequency according to the initial vibration frequency and the target vibration frequency is executed, the vibration adjusting frequency is obtained according to the updated target vibration frequency, a new vibration signal is generated and applied to the equipment to be descaled, and the target vibration frequency is not updated until a descaling finishing condition is met.
The target vibration frequency is continuously updated, so that the updated target vibration frequency can meet the condition that the current dirt generates resonance, the dirt is effectively removed, and the dirt is completely removed.
Further, the method further includes step S410: and when the descaling ending condition is met, ending the descaling treatment.
In another embodiment, the descaling method is used for removing dirt in the waterway pipeline, and in this embodiment, the step S408 further includes: when the first application time of the vibration signal reaches the first time, acquiring a water quality detection value of the equipment to be descaled; when the water quality detection value is greater than or equal to the preset threshold value and the target vibration frequency is less than the upper limit frequency of the resonance frequency range, updating the target vibration frequency according to the updating rule; and returning to the step of obtaining the vibration adjusting frequency according to the initial vibration frequency and the target vibration frequency until the descaling ending condition is met.
The first application time length refers to the time length from the moment when the vibration signal is applied at the vibration adjusting frequency of the current vibration signal to the current moment; the first duration is a preset value. In particular, the first application period may be recorded by a timer. The water quality detection value refers to the content of dirt in the water flow of the pipeline. Specifically, a water quality detector can be installed at the outlet of the waterway pipeline, and the water quality detection value is obtained by sampling and detecting water flow by the water quality detector. The preset threshold value can be set as a standard value for defining the quality of water, and specifically can be set as a water quality detection value of water flow when descaling is not performed. When the water quality detection value is smaller than the preset threshold value, the water quality is not good, and when the water quality detection value is larger than or equal to the preset threshold value, the water quality requirement standard is met, and the water quality is good.
In this embodiment, whether the first application time reaches a first preset time is judged, and when the first application time of the vibration signal reaches the first time, the water quality detection value of the device to be descaled is obtained. Further judging whether the current water quality detection value is smaller than a preset threshold value or not and whether the current target vibration frequency reaches the upper limit frequency F of the resonance frequency range or notmaxAnd when the water quality detection value is greater than or equal to the preset threshold value and the target vibration frequency is less than the upper limit frequency of the resonance frequency range, updating the target vibration frequency according to the updating rule, returning to execute the step of obtaining the vibration adjusting frequency according to the initial vibration frequency and the target vibration frequency, obtaining the vibration adjusting frequency according to the updated target vibration frequency, generating a new vibration signal and applying the new vibration signal to the equipment to be descaled until a descaling finishing condition is met, and not updating the target vibration frequency.
The detected water quality detection value is compared with a preset threshold value, when the water quality detection value is larger than or equal to the preset threshold value, the current water quality is better, and at the moment, no dirt or excessive dirt is stripped from the pipeline and flows out along with the water flow. That is, the current target vibration frequency reached no longer satisfies the resonance condition of the currently non-peeled dirt or the dirt has been completely removed. If the current achieved target vibration frequency does not meet the resonance condition of the currently unpeeled dirt, updating the vibration signal applied to the equipment to be descaled by updating the target vibration frequency so as to achieve the resonance condition of the currently unpeeled dirt and ensure that the dirt is effectively removed; if the dirt has been completely removed, i.e. the descaling end condition is reached, the descaling process is ended.
Further, the descaling method further comprises the following steps: and when the water quality detection value is smaller than the preset threshold value and the second application time of the vibration signal reaches the second time, returning to the step of obtaining the water quality detection value of the equipment to be descaled.
The second application time length refers to the continuous application time length of the vibration signal after the water quality detection value is compared and judged with a preset threshold value. The second duration is a preset value, the second duration may be smaller than or greater than the first duration, or may be equal to the first duration, and the specific value may be configured as required, which is not limited herein.
In this embodiment, when the first application time reaches the first time or the second application time reaches the second time, if the water quality detection value is smaller than the preset threshold, it indicates that the current water quality is poor, and the scale in the pipeline is peeled off, at this time, a vibration signal is continuously applied to the equipment to be descaled, with the current target vibration frequency as a target, so that the scale meeting the current resonance condition is completely peeled off the pipeline as much as possible. And when the second application time length of the vibration signal reaches the second time length, acquiring the water quality detection value of the equipment to be descaled again to judge whether the current water quality detection value is smaller than the preset threshold value, and determining whether to continuously apply the vibration signal to the equipment to be descaled by taking the current target vibration frequency as a target or update the target vibration frequency according to the judgment result.
In one embodiment, the descaling-end condition includes: the target vibration frequency reaches the upper limit frequency of the resonance frequency range. That is, when the water quality detection value is greater than or equal to the preset threshold value, the water quality is good, and if the currently operated target vibration frequency also reaches the upper limit frequency of the resonance frequency range, the descaling treatment is finished. Because the resonant frequency range includes all possible frequencies of dirt resonance, dirt with different resonant conditions can be cracked and stripped off the pipeline by continuously updating the target vibration frequency, and when the target vibration frequency reaches the upper limit frequency FmaxIn time, dirt can be ensured to be cleaned.
Further, when the descaling ending condition is met, the step of ending the descaling treatment comprises the following steps: and when the descaling ending condition is met, generating a vibration stopping signal and exiting the descaling mode. The vibration stopping signal is used for controlling the vibrator to stop vibrating, and when the device applying the vibration signal is the vibrator, the vibration stopping signal is used for controlling the vibrator to stop vibrating.

The time judging module is used for judging whether the first applying time length of the vibration signal reaches a first time length; the water quality detection value acquisition module is used for acquiring a water quality detection value of the equipment to be descaled when the first application time of the vibration signal reaches the first time length; the water quality judgment module is used for judging whether the water quality detection value is smaller than a preset threshold value or not; the frequency judging module is used for judging whether the target vibration frequency reaches the upper limit frequency of the resonance frequency range. In this implementation, the target frequency updating module is further configured to update the target vibration frequency according to the updating rule when the water quality detection value is greater than or equal to the preset threshold and the target vibration frequency is less than the upper limit frequency of the resonance frequency range.
The detected water quality detection value is compared with a preset threshold value, when the water quality detection value is larger than or equal to the preset threshold value, the current water quality is better, and at the moment, no dirt or excessive dirt is stripped from the pipeline and flows out along with the water flow. That is, the current target vibration frequency reached no longer satisfies the resonance condition of the currently non-peeled dirt or the dirt has been completely removed. If the current achieved target vibration frequency does not meet the resonance condition of the currently unpeeled dirt, updating the vibration signal applied to the equipment to be descaled by updating the target vibration frequency so as to achieve the resonance condition of the currently unpeeled dirt and ensure that the dirt is effectively removed; if the dirt has been completely removed, i.e. the descaling end condition is reached, the descaling process is ended.
Further, the time judgment module is further configured to judge whether a second application duration of the vibration signal reaches a second duration; the water quality detection value acquisition module is also used for acquiring the water quality detection value of the equipment to be descaled when the water quality detection value is smaller than a preset threshold value and the second applying time of the vibration signal reaches a second time length.
In this embodiment, when the first application time reaches the first time or the second application time reaches the second time, if the water quality detection value is smaller than the preset threshold, it indicates that the current water quality is poor, and the scale in the pipeline is peeled off, at this time, a vibration signal is continuously applied to the equipment to be descaled, with the current target vibration frequency as a target, so that the scale meeting the current resonance condition is completely peeled off the pipeline as much as possible. And when the second application time length of the vibration signal reaches the second time length, acquiring the water quality detection value of the equipment to be descaled again to judge whether the current water quality detection value is smaller than the preset threshold value, and determining whether to continuously apply the vibration signal to the equipment to be descaled by taking the current target vibration frequency as a target or update the target vibration frequency according to the judgment result.
Further, the descaling device also comprises an ending module which is used for ending the descaling treatment when the descaling ending condition is met. In particular, it may be used to generate a vibration stop signal and exit the descaling mode when a descaling end condition is met.
Through the descaling device, the equipment to be descaled does not need to stop running in the whole descaling process, and descaling treatment is completed under the condition that the equipment to be descaled normally works. Meanwhile, compared with the traditional method for descaling by adopting chemical agents, the method avoids the corrosion of equipment to be descaled by the chemical agents and the pollution of water flow by the chemical agents.
