Also, it should be understood that in the present embodiment, the number of the first ultraviolet lamp 201 and the second ultraviolet lamp 202 each includes at least one. For example, the first ultraviolet lamp 201 and the second ultraviolet lamp 202 are included, or three first ultraviolet lamps 201 and three second ultraviolet lamps 202 are included, which will not be described herein.
The first embodiment is as follows:
referring to fig. 3, a flow diagram of an air purification control method is shown. The air purification control method specifically comprises the following steps:
1) an acquisition step:
acquiring real-time index parameters of N different indexes representing the ambient air quality;
2) a comparison and judgment step:
comparing the real-time index parameters of the N different indexes with the corresponding preset index threshold values, and judging whether the error value of each real-time index parameter and the prestored index parameter is within an allowable error range;
3) and a control instruction output step:
according to a preset bit order, when a real-time index parameter appearing for the first time in N different indexes is larger than a preset index threshold value of the real-time index parameter and an error value of the real-time index parameter and a prestored index parameter is in an allowable error range, outputting a prestored control instruction corresponding to the prestored index parameter value; when the real-time index parameter is larger than the preset index threshold value for the first time in the N different indexes and the error value of the real-time index parameter and the prestored index parameter value is not in the allowable error range, outputting an automatic control instruction corresponding to the real-time index parameter based on the wind speed of the fan and the starting number alternate adjustment rule of the ultraviolet lamps; wherein N is a positive integer greater than or equal to 1.
That is, the air purification control method of this embodiment includes three basic steps, first obtaining a real-time index parameter, then comparing the obtained real-time index parameter with a pre-stored index threshold and a pre-stored index parameter, and finally outputting a corresponding control instruction according to a comparison result.
The indexes of the ambient air quality include various indexes, such as harmful gas, harmful organic matters, germs and the like, and also can be indexes of reacting air quality particles. Specifically, in the present embodiment, the emphasis is placed on harmful gases, harmful organic substances, and germs, such as virus type content, formaldehyde gas, ozone gas, and other TVOC gases, and these air quality indicators can be obtained by corresponding sensors.
When specific air purification control is performed, in this embodiment, first, real-time index parameters of N (N is a positive integer greater than or equal to 1) different indexes reflecting the quality of ambient air are obtained, and these real-time index parameters are transmitted to the controller as electric signals, and the controller processes these electric signals.
After receiving N real-time detection parameters of different indexes, performing two specific execution sub-steps in the comparison and judgment step.
Firstly, comparing the real-time index parameter with a corresponding preset index threshold value; then, whether the error value of the real-time index parameter and the pre-stored index parameter exceeds the allowable error range is judged.
It should be understood that the preset index threshold and the pre-stored index parameter are stored in the memory of the air purification apparatus in the embodiment. The preset index threshold is set based on whether the human health is damaged or not. For example, the numerical values of the preset index threshold values of different indexes are performed according to national standards. Of course, the setting may be performed with a parameter value higher than the national standard. For example, the concentration of ozone is set at 0.08ppm standard. The pre-stored index parameters are data recorded by the air purification equipment in the working process or received data transmitted by external equipment. Generally, the pre-stored index parameter is a data set of an air index parameter when the air quality index purification efficiency is highest in a specific area and a specific time period and a control instruction (controlling the rotating speed of the fan and/or the ultraviolet operating state) corresponding to the air index parameter. Namely, the pre-stored index parameter may be self data stored by the device or received data provided by external devices, such as data provided by other air purification devices or data provided by remote monitoring devices.
And comparing the real-time index parameters of the N different indexes with the corresponding preset index threshold, namely comparing the real-time index parameters of the N different indexes received in the same batch with the corresponding preset index threshold independently. For example, the N indexes include a virus index, a bacteria index, a formaldehyde index, an ozone index and a TVOC index, the received real-time index parameters include a virus index real-time index parameter, a bacteria index real-time index parameter, a formaldehyde index real-time index parameter, an ozone index real-time index parameter and a TVOC index real-time index parameter, when the comparison is performed, the virus index real-time index parameter is compared with a preset index threshold of the virus, the bacteria index real-time index parameter is compared with a preset index threshold of the bacteria, the formaldehyde index real-time index parameter is compared with a preset index threshold of the formaldehyde, the ozone index real-time index parameter is compared with a preset index threshold of the ozone, and the TVOC index real-time index parameter is compared with a preset index threshold of the TVOC.
Similarly, when the error value of the real-time index parameter and the pre-stored index parameter exceeds the set range, the judgment is also performed one by one. Specifically, for example, the real-time index parameter Z of ozone is compared with the pre-stored index parameter Z' of ozone, and if the error value between the two is Δ Z, it is determined whether the value of Δ Z exceeds the set standard. For example, if the allowable error range is ± 1%, the judgment is made
Whether or not it is greater than 1%. Of course, it should be understood that the error range is preset and can be set according to different air indexes.
After the comparison and judgment in the step 2), the step 3) is started, and a corresponding control command is output according to the comparison and judgment result in the step 2).
In detail, according to a preset bit order, when a real-time index parameter appearing for the first time in N different indexes is larger than a preset index threshold value of the real-time index parameter and an error value of the real-time index parameter and a prestored index parameter is in an allowable error range, outputting a prestored control instruction corresponding to the prestored index parameter value; and when the real-time index parameter is larger than the preset index threshold value for the first time in the N different indexes and the error value of the real-time index parameter and the prestored index parameter value is not in the allowable error range, outputting an automatic control instruction corresponding to the real-time index parameter based on the wind speed of the fan and the starting number alternate adjustment rule of the ultraviolet lamps.
Wherein, the sequence according to the preset order refers to the sequence from high to low harm to human health. For example, the air quality index includes virus, bacteria, formaldehyde, ozone, and TVOC, and the order of the level is set as virus > bacteria > formaldehyde > ozone > TVOC in this embodiment. Of course, the present invention is not limited to this, and the present description is only described as a specific example, and may be any other standard that meets the human health.
Namely, the control instruction output in the step 3) is divided into two different output conditions. One is that: A. according to the preset position sequence, when the real-time index parameter is larger than the preset index threshold value for the first time and the error value of the real-time index parameter and the prestored index parameter is in the allowable range, the control instruction corresponding to the prestored index parameter is directly adopted to be directly output. The other is as follows: B. and when the real-time index parameter is larger than the preset index threshold value for the first time but the error between the real-time index parameter and the pre-stored index parameter is not within the allowable error range, outputting an automatic control instruction according to a set rule.
It should be understood that the pre-stored index parameter is an index parameter value stored in the air purification device and having the fastest control index purification efficiency formed in the purification process, and a control instruction corresponding to the index parameter value, or externally input data adapted to the air purification device for optimal purification, so that when the first condition of the method exists, the pre-stored control instruction can be directly output to the air purification device to adjust the rotating speed of the fan of the air purification device and/or the working state of the ultraviolet lamp, so as to achieve rapid air purification treatment. Because the pre-stored index parameter belongs to the optimal value of the air purification equipment in the working state, the air purification equipment can realize the air purification at the fastest speed so as to meet the requirement of reducing harmful indexes to the minimum.
And when the corresponding error value exceeds the allowable error range, outputting an automatic control command according to a set rule. In particular, the predetermined rule is preset, which can be preset according to different requirements and use occasions. Specifically, in this embodiment, the predetermined rule is based on an alternating adjustment rule of the wind speed of the fan and the number of turned-on ultraviolet lamps, and outputs an automatic control command. In a specific embodiment, the predetermined rule may be that when the error value exceeds the error range, an automatic control instruction is output for the first time, that is, the rotation speed of the fan is adjusted, and after the rotation speed of the fan is adjusted for a certain time, the detected corresponding real-time index parameter still exceeds the preset index threshold, the automatic control instruction is output for the second time; i.e. to adjust the operating state of the uv lamp. For example, if the first occurrence of formaldehyde exceeds a preset index threshold, the output automatic control instruction is to reduce the wind speed of the fan. And after the wind speed is reduced by 20s, outputting an automatic control instruction for the second time if the detected real-time index parameter of the formaldehyde still exceeds the preset index threshold value, wherein the automatic control instruction for the second time is used for controlling the fan to recover the wind speed of the last time and controlling to increase the working quantity of the ultraviolet lamps. And if the real-time index parameters of the formaldehyde still exceed the preset threshold value after a period of time (for example, 30s) after the working number of the ultraviolet lamps is increased, outputting an automatic control instruction for the third time, wherein the automatic control instruction controls the fan to reduce the wind speed. And if the real-time index parameter of the formaldehyde after the purification treatment is still higher than the preset index threshold value, repeating the steps, namely, the steps of reducing the wind speed of the fan and turning on the working number of the ultraviolet lamps are continuously and alternately repeated until the real-time index parameter of the formaldehyde is lower than the preset index threshold value.
Wherein, it should be understood that, when the error value falls within the allowable error value range during the continuous adjustment process for the error value exceeding the allowable error range value, step a is executed.
Of course, the above embodiments only list a specific established rule, and the core of the rule is to automatically and alternately control the wind speed of the fan and the opening number of the ultraviolet lamps. Besides, the number of the ultraviolet lamps can be adjusted firstly, and then the wind speed of the fan can be adjusted. In summary, the established rule in the technical scheme of the invention is to continuously and repeatedly control the wind speed of the fan and the working number of the ultraviolet lamps so as to achieve effective purification of the air. It should be understood that if the variation amount of the wind speed of the fan is adjusted each time and the number of the ultraviolet lamps is increased or decreased each time is changed, the method still falls into the protection scope of the present invention.
In a specific application embodiment, according to a preset order, the real-time index parameters include a virus index parameter X, a formaldehyde index parameter Y, an ozone index parameter Z and a TVOC index parameter S; x0Is a preset threshold value of a virus index parameter, Y0Is a preset threshold value of a formaldehyde index parameter, Z0Is a preset threshold value of an ozone index parameter, S0Is a preset threshold value of the TVOC index parameter. Of course, the virus in this embodiment may be a type of virus that can be rapidly detected and fed back in the prior art. And in other embodiments, a bacterial indicator parameter is included, the bacterial indicator having a ranking after the viral indicator and before the formaldehyde indicator. During specific control, one of the following steps is executed:
c1: if X > X0If the error value between the real-time index parameter X and the prestored index parameter X 'is within the allowable error range, outputting a prestored control instruction corresponding to the prestored index parameter X'; and when the error value of the real-time index parameter X and the pre-stored index parameter X' is out of the allowable error range, outputting a first automatic control instruction corresponding to the real-time index parameter X, wherein the first automatic control instruction is used for controlling a fan of the air purification equipment to reduce the air speed and/or controlling all ultraviolet lamps to work. Specifically, the first automatic control command may be generated according to a predetermined rule. In detail, the wind speed can be reduced firstly, and then the working number of the ultraviolet lamps is increased; or the working number of the ultraviolet lamps is increased firstly, and after purification is carried out for a certain time (for example, 20s), if the real-time index parameter X still exceeds the preset index parameter X0, the wind speed of the fan 30 is controlled to be reduced; alternating until the real-time index parameter X is smaller than the preset index parameter X0. Of course, the wind speed of the fan can be reduced and the working number of the ultraviolet lamps can be increased; for example, first, the first wind speed is reduced and a UV lamp is simultaneously operated, so that after a period of time (for example, 20s), if the real-time index parameter X still exceeds the preset index parameter threshold, the first wind speed is continuously reduced and a UV lamp is simultaneously operatedAnd the process is carried out until the real-time index parameter X is lower than the pre-stored index parameter X'.
C2: if X < X0，Y＞Y0，Z＜Z0And the error value of the real-time index parameter Y and the prestored index parameter Y 'is in the allowable error range, outputting a prestored control instruction corresponding to the prestored index parameter Y'; and when the error value of the real-time index parameter Y and the pre-stored index parameter Y' is out of the allowable error range, outputting a second automatic control instruction corresponding to the real-time index parameter Y, wherein the second automatic control instruction is used for controlling a fan of the air purification equipment to reduce the air speed and/or controlling all ultraviolet lamps to work. In this scheme, the second automatic control instruction generates control corresponding to adjustment of the wind speed of the fan and adjustment of the working quantity of the ultraviolet lamps according to a set rule, and the specific control is the same as the step C1, which is not repeated herein.
C3: if X < X0，Z＞Z0And the error value of the real-time index parameter Z and the prestored index parameter Z 'is in the allowable error range, outputting a prestored control instruction corresponding to the prestored index parameter Z'; and when the error value of the real-time index parameter Z and the pre-stored index parameter Z' is out of the allowable error range, outputting a third automatic control instruction corresponding to the real-time index parameter Z, wherein the third automatic control instruction is used for controlling a fan of the air purification equipment to reduce the air speed and/or controlling at least part of ultraviolet lamps with the light-emitting wavelength of 185nm to stop working. The control of the scheme is mainly aimed at the situation of two ultraviolet lamps, namely a 185nm ultraviolet lamp and a 254nm ultraviolet lamp. Since ozone is harmful to human body, in this embodiment, when the real-time index parameter X of the virus is lower than the preset index threshold value X0Mainly remove ozone. Ozone is easily generated by irradiating air with a 185nm ultraviolet lamp, while the 254nm ultraviolet lamp has a decomposing effect on ozone. Thus, by adjusting the wind speed of fan 30 and reducing the number of 185nm UV lamps and increasing 154 the number of UV lamps. During specific control, the first generated third automatic control instruction controls the fan to reduce the wind speed, and after the third automatic control instruction is maintained for a period of time (20s), if Z is still larger than Z0Then a third automatic control command is generated for the second time for increasingAdding a 254nm ultraviolet lamp, and increasing the work number of the 254nm ultraviolet lamps until Z is less than Z0(ii) a If the 254nm UV lamp is fully on, Z is still greater than Z0Continuously outputting a third automatic control instruction to control and reduce the working quantity of the 185nm ultraviolet lamps until Z is less than Z0. Of course, the fan speed may not be reduced first, and the third automatic control command is executed according to the following control route, namely, the number of 254nm ultraviolet lamps is increased, the fan speed is reduced to the acceptable lowest wind speed, and finally the number of 185nm ultraviolet lamps is reduced until the ozone is reduced below the preset index threshold.
