In a second aspect, referring to fig. 5, an embodiment of the present invention provides a method for controlling an outdoor power ventilator, for controlling an outdoor power ventilator of a multifunctional building wall according to any one of the first aspect, the method includes the following steps:
and 504, regulating and controlling the outdoor power ventilator according to the at least one target wind speed gear and the dehumidification time information corresponding to each target wind speed gear.
The embodiment of the invention provides a regulation and control method of an outdoor power ventilator, which comprises the steps of acquiring a current temperature value acquired by a temperature sensor arranged on outer-layer heat absorption glass and a current humidity value acquired by a humidity sensor arranged on a moisture absorption structure, knowing current water content information of the moisture absorption structure and current temperature information of the outer-layer heat absorption glass, then estimating a dehumidification quantity-time curve corresponding to the current temperature value at each candidate wind speed gear of the outdoor power ventilator respectively, knowing dehumidification conditions of different temperatures at different wind speed gears of the outdoor power ventilator respectively, then determining a plurality of target wind speed gears from a plurality of candidate wind speed gears according to the dehumidification quantity-time curves corresponding to the current humidity value and the current temperature value at each candidate wind speed gear of the outdoor power ventilator respectively, and determining the dehumidification time information corresponding to each target wind speed gear, wherein the obtained dehumidification time information corresponding to the plurality of target wind speed gears and the plurality of target wind speed gears has relatively high reference value due to the consideration of the influence of temperature and wind speed on the dehumidification effect, and then regulating and controlling the outdoor power ventilator according to the dehumidification time corresponding to the plurality of target wind speed gears and each target wind speed gear, so that the dehumidification effect is ensured.
It should be noted that the regulation and control of the outdoor power ventilator are real-time regulation and control according to the temperature value of the outer layer heat absorption glass collected by the temperature sensor and the humidity value of the moisture absorption structure collected by the humidity sensor, so that the dehumidification effect is ensured.
Specifically, the dehumidification time information includes, but is not limited to, a dehumidification start time and a dehumidification duration, so that the operation sequence and the operation time of a plurality of target wind speed gears can be represented, and the dehumidification effect is ensured.
It should be noted that the regulation and control method of the outdoor power ventilator provided in this embodiment can be applied to the controller in the outdoor power ventilator of the multifunctional building wall body as described in the first aspect.
In one embodiment, the estimating a respective dehumidification-time curve of the current temperature value at each candidate wind speed gear of the outdoor power ventilator comprises:
acquiring historical dehumidification data of the outdoor power ventilator in a preset time period before the current moment;
acquiring a variable temperature range of a current temperature value, and determining a temperature interval of the current temperature value according to the variable temperature range;
screening out reference dehumidification data corresponding to the temperature interval from the historical dehumidification data;
and for each candidate wind speed gear of the outdoor power ventilator, estimating a dehumidification quantity-time curve corresponding to the temperature interval according to a historical humidity value corresponding to the candidate wind speed gear in the reference dehumidification data and a time point corresponding to the historical humidity value, and determining the dehumidification quantity-time curve corresponding to the temperature interval as the dehumidification quantity-time curve corresponding to the candidate wind speed gear corresponding to the current temperature value.
In the embodiment, the dehumidification-time curve is obtained through historical dehumidification data of the moisture absorption material, so that the dehumidification-time curve can accurately reflect the real dehumidification condition.
Specifically, the historical dehumidification data comprises temperature values acquired by temperature sensors and humidity values acquired by humidity sensors corresponding to each time point respectively when the outdoor power ventilator dehumidifies.
It should be noted that, considering that the regeneration performance of the absorbent structure may be affected after a certain period of use, in order to reflect the regeneration effect of the absorbent structure more accurately, the historical dehumidification data of the absorbent structure needs to be analyzed to know the regeneration performance of the absorbent structure.

Here, the embodiment of the present invention is not intended to limit the preset time period before the present moment, and may be set in combination with the actual condition of the moisture absorbing material.
It should be further noted that, considering that the temperature value of the outer layer heat absorption glass is easily affected by the external environment and is usually unstable, in order to ensure the accuracy of the dehumidification amount-time curve corresponding to the obtained temperature value, the fluctuation condition of the temperature value can be predicted, so as to determine the temperature interval corresponding to the temperature value, and the dehumidification amount-time curve corresponding to the temperature value is represented by the dehumidification amount-time curve corresponding to the temperature interval, so as to ensure the reference value of the dehumidification amount-time curve.
As a feasible implementation manner, the abscissa is time, the ordinate is humidity value, reference humidity-time curves corresponding to a plurality of temperature values in a temperature interval are drawn, the reference humidity-time curves corresponding to the temperature values are fused to obtain a target humidity-time curve, and the target humidity-time curve is converted to obtain a dehumidification amount-time curve. Wherein, the conversion of the target humidity-time curve can be realized by the following steps: for each time point in the target humidity-time curve, determining the difference value between the humidity value of the time point and the humidity value of the time point before the time point, and determining the difference value as the dehumidification amount, thereby realizing the conversion of the target humidity-time curve.
