Description
Technical Field
The invention relates to the technical field of tower fan control, in particular to a tower fan wind speed control method, a computer readable storage medium and a tower fan.
Background
The existing tower fan can only set a fixed mode and wind speed, and the wind speed cannot be automatically controlled according to the distance between a human body and the tower fan. When human and tower fan distance were close, the wind speed was too big leads to human uncomfortable easily, and human and tower fan distance when far away, and the air supply distance can not blow the people inadequately, and the wind speed of tower fan can't carry out automatic adjustment according to actual demand, can't improve user's use comfort, also can't reach the effect of rational utilization energy consumption, is not conform to the direction of current development.
Disclosure of Invention
Aiming at the defects of the prior art, the invention realizes a control method for automatically adjusting the wind speed according to the distance between the user and the tower fan, and improves the comfort of the user.
In order to achieve the purpose, the invention adopts the following technical scheme:
a tower fan wind speed control method comprises the steps of detecting the distance L between a human body and a tower fan when the tower fan is in a specific mode, and comparing the detected distance with a preset reference distance to further determine the wind speed selection of the tower fan. Through measuring and calculating the distance of human body and tower fan to according to the wind speed of measuring apart from automatic control tower fan, revise current wind speed in order to realize suitable air supply distance, can let the tower fan have more humanized automatic wind speed control, when avoiding appearing human and tower fan distance far away, the air supply distance can not blow the people inadequately, perhaps human and tower fan distance when being close, the too big human unwell condition that leads to of wind speed, simultaneously can the rational utilization energy consumption, avoid extravagant.
Further, the detecting the distance between the human body and the tower fan is specifically to control the generator to emit a detection wave with a fixed wavelength, receive a reflection signal by the receiver, and calculate the distance between the human body and the tower fan according to the emission and reception time difference. The mode of detecting the distance can realize accurate detection effect, the range of the extensible distance is wider, detection in a wider range is realized, and the method has better application prospect.
Further, the preset reference distance includes Lmax, Lmid, and Lmin, where Lmax represents the maximum reference distance, Lmid represents the median reference distance, and Lmin represents the minimum reference distance. Through setting of different reference distances and judgment and comparison according to the reference distances, the setting of the wind speed can be more reasonable, and the accuracy of controlling the wind speed is guaranteed.
Further, the specific mode is specifically a directional air supply mode, and when the tower fan is determined to be in the directional air supply mode, the distance L between the human body and the tower fan is controlled to be detected, otherwise, the original state is maintained. The detection is started only in the directional air supply mode and is used as a signal of a switch, unnecessary resource waste caused by the fact that the tower fan is in a detection state all the time is avoided, meanwhile, the setting is more targeted, and the actual requirements of users are met.
Further, when the receiver does not receive the reflected signal, it needs to further determine whether the interval time is reached, if the interval time is reached, the generator is controlled to continue to emit the detection wave with the fixed wavelength, and if the interval time is not reached, the generator is controlled to emit the detection wave with the fixed wavelength after waiting for the interval time. The detection distance is prevented from being continuously transmitted, the detection error is caused due to the fact that the feedback of signals is too frequent, subsequent calculation and judgment are not facilitated, the waiting time of the interval time is set, and the accuracy of the detection distance can be effectively guaranteed.
Further, the comparison between the detected distance and the preset reference distance comprises a first state, a second state, a third state and a fourth state, wherein the first state is that L is more than or equal to Lmax, the second state is that Lmid is less than or equal to L less than Lmax, the third state is that Lmin is more than or equal to L less than Lmid, and the fourth state is that L is less than Lmin. The detection distance and the reference distance are classified in detail, all possible detection conditions are covered, the use experience of a user is greatly improved, and the use comfort is enhanced.
And further, when the detected distance is compared with a preset reference distance and is in a first state, further judging whether the wind speed is automatic or not, if so, controlling the wind speed to operate according to an X value, otherwise, adjusting the wind speed according to a Y value, wherein the X value and the Y value are preset parameter values. When the sensed distance is greater than the maximum reference distance, indicating that the person is a significant distance from the tower fan, in which case the wind speed of the tower fan is adjusted to a maximum to ensure that the person is able to be blown.
And further, when the detected distance is in a second state compared with a preset reference distance, further judging whether the wind speed is automatic or not, if so, controlling the wind speed to operate according to the M value, and if not, keeping the current wind speed unchanged, wherein the M value is a preset parameter value. When the detection distance is in the position of the maximum reference distance and the middle reference distance, the wind speed is adaptively adjusted, the condition that the wind blowing to the human body is not too large or too small is ensured, and the comfort of the human body is ensured.
And further, when the detected distance is compared with a preset reference distance and is in a third state, further judging whether the wind speed is automatic or not, if so, controlling the wind speed to operate according to a P value, otherwise, adjusting the wind speed according to an S value, wherein the P value and the S value are preset parameter values. When the detection distance is in the position of the minimum reference distance and the middle reference distance, the distance between the human body and the tower fan is moderate, and the wind speed can be reduced adaptively to adapt to use.
Further, when the detected distance is in a fourth state compared with the preset reference distance, the wind speed is controlled to operate according to the value N. When the detection distance is smaller than the minimum reference distance, the human body is close to the tower fan, and under the condition, the wind speed must be reduced, so that the discomfort caused by the fact that the human body is blown by overlarge wind power is avoided.
