In the process, the water-free device is used as an internet of things device and needs to communicate with a client or other internet of things devices, the speed regulation is realized by changing voltage or current, level fluctuation in a system is easily caused, the fluctuation has direct influence of an electric signal in the system, and the level is unstable due to magnetic field change caused by voltage or current change. Therefore, the invention also comprises level interference removal after speed regulation.
In the present application, the level interference of the communication bus is mainly considered, so that the interference of the 485 bus needs to be located and stabilized.
The method provided by the invention determines the speed regulation frequency of the rotating speed of the motor through the wind speed and the water level, when the rotating speed is regulated, the amplitude of each speed regulation is smaller according to the dynamic speed regulation frequency, the difference value of the two speed regulation is smoother, and the voltage/current fluctuation during the speed regulation is reduced; after the speed regulation of the rotating speed is carried out, the level is further stabilized, and the stability of the level before and after the speed regulation is ensured.
In one embodiment, the determining the fan speed regulation mode according to the values of the wind speed sensor and the water level sensor comprises:

if so, setting the fan adjusting mode to be a high-frequency speed adjusting mode;
judging whether the output voltage of the wind speed sensor is less than 10V or not and whether the numerical value ratio of the water level sensor is less than 1/2 or not;
and if so, setting the fan adjusting mode to be a low-frequency speed adjusting mode.
In the embodiment, the output of the wind speed sensor is usually in the range of 0V-15V, and when the current output is greater than or equal to 10V, the wind speed at the moment is higher; meanwhile, when the ratio of the value of the water level sensor is greater than or equal to 1/2, the water level at the moment is already high, and the speed of the fan needs to be reduced. Conversely, when the current output is lower than 10V, it means that the wind speed at that time is low; meanwhile, when the numerical value ratio of the water level sensor is less than 1/2, the water level at the moment is lower, and the potential of the device can be fully utilized by increasing the speed of the fan. It is understood that the numerical ratio of the water level sensor herein refers to a ratio of the current detection value to the maximum water level.
