Specifically, in order to more fully describe the above embodiments, the parameter detection unit includes a voltage detection unit, and the operation parameter includes a voltage parameter.
The initial operating parameter (i.e., initial operating voltage) is recorded as VF0, the current operating parameter (i.e., current operating voltage) is recorded as VFn, and the parameter difference between the two is VF00VFn, the fan is in the unopened working state if (VF)0-VFn)<e1, wherein e1 is a first threshold value, the fan is controlled not to be started; if e1 is less than or equal to (VF)0-VFn)<e2, starting the fan and enabling the fan to operate at c1, wherein e2 is a second threshold value, and c1 is a first rotating speed; if (VF)0-VFn) ≧ e2, the fan is turned on and operated at c2, where c2 is the second rotational speed. Thus, by determining VF0A size between-VFn and e1, e2, able to be according to VF0Respective sizes between-VFn and e1, e2The relationship is respectively corresponding to the fan driven to operate at a certain rotation speed, that is, corresponding to the fan control modes of different embodiments of the sterilization control device, obviously, the relationship can be according to VF0The corresponding size relationship between the ultraviolet sterilization component-VFn and the corresponding size relationship between the ultraviolet sterilization component-e 1 and the ultraviolet sterilization component-e 2 are used for separately knowing the required heat dissipation of the ultraviolet sterilization component under a certain working state, so that the fan is correspondingly driven to dissipate the heat of the ultraviolet sterilization component, and the heat dissipation effect is good.
Similarly, when the fan is started, the parameter difference between the fan and the fan is still VF0-VFn, if (VF)0-VFn)<e10(e10<e1) Controlling the fan to stop working, wherein e10 is a third threshold; if the blower is operating at c2, and (VF)0-VFn)<e20(e1<e20<e2) And changing the fan to operate at c1, wherein e20 is a fourth threshold, and otherwise, keeping the fan operating at the current rotating speed (which indicates that the working conditions of the ultraviolet sterilization control device at this time are not greatly different before and after the fan is started, and the rotating speed of the fan can be kept to perform heat dissipation treatment on the fan), wherein c1 is less than c 2.
By judging VF0A size between-VFn and e10, e20, able to be according to VF0The corresponding size relationship between-VFn and e10, e20 respectively adjusts the operation of the fan at a certain rotation speed, i.e. the fan control mode under different embodiments of the sterilization control device, obviously, according to the VF0The corresponding size relationship between the ultraviolet sterilization component-VFn and the corresponding size relationship between the ultraviolet sterilization component-e 10 and the ultraviolet sterilization component-e 20 are used for separately knowing the required heat dissipation of the ultraviolet sterilization component under a certain working state, so that the fan is correspondingly driven to dissipate the heat of the ultraviolet sterilization component, and the heat dissipation effect is good.
In one embodiment of the present application, the parameter detection component comprises a temperature measurement component, and the operating parameter comprises a temperature parameter;
the temperature measurement component acquires temperature parameters of the ultraviolet sterilization component according to a preset time interval;
the control assembly controls the working state of the fan according to the temperature parameters.
Specifically, the temperature parameter in this embodiment can directly characterize the operating condition of ultraviolet sterilization part to make the control assembly can control the operating condition of fan according to the temperature parameter, thereby realize the heat dissipation for ultraviolet sterilization part.
In one embodiment of the application, before the control component controls the ultraviolet sterilization component to be started, the control component controls the fan to operate at a first rotating speed in response to the temperature parameter being greater than or equal to a first temperature threshold and smaller than a second temperature threshold, and after the rotating speed of the fan is constant, the control component controls the ultraviolet sterilization component to be started. Under this condition, the temperature parameter of ultraviolet sterilization part is higher, consequently need dispel the heat to it to control the fan correspondingly and open, in order to realize the heat dissipation processing to ultraviolet sterilization part, guarantee that ultraviolet sterilization part has normal operating condition, it needs to explain that the concrete parameter of first temperature threshold, second temperature threshold can be confirmed according to parameters, wind channel condition test and fan self parameter etc. of ultraviolet sterilization controlling means who uses, and it does not have the restriction in this embodiment.
In one embodiment of the application, in response to the temperature parameter being greater than or equal to a second temperature threshold, the control assembly controls the fan to operate at a second rotating speed, and after the rotating speed of the fan is constant, the control assembly controls the ultraviolet sterilization part to be started, wherein the second rotating speed is greater than the first rotating speed. Under this kind of circumstances, compare the last embodiment "before control assembly control ultraviolet sterilization part opens, respond to temperature parameter more than or equal to first temperature threshold and be less than the second temperature threshold, control assembly control fan is with first rotational speed operation, after the rotational speed of fan is invariable, control assembly control ultraviolet sterilization part opens, the temperature parameter of ultraviolet sterilization part is bigger relatively, consequently, need dispel the heat and make the rotational speed of fan further improve to it, thereby satisfy the heat dissipation demand of ultraviolet sterilization part, guarantee that ultraviolet sterilization part has normal operating condition.
In one embodiment of the application, after the control component controls the ultraviolet sterilization part to be started, the control component controls the fan to stop running in response to the temperature parameter being less than the third temperature threshold value. Under this kind of circumstances, because the fan has opened, then the temperature parameter of ultraviolet sterilization part can be cut down along with the fan heat dissipation, consequently carry out the analysis again to this type of temperature parameter, if the temperature parameter of ultraviolet sterilization part is further less than the third temperature threshold value, then it is good to explain ultraviolet sterilization part state, need not to continue to dispel the heat, consequently, under guaranteeing that ultraviolet sterilization part has normal operating condition, can drive the fan correspondingly and stop, avoids the energy extravagant.
In one embodiment of the present application, when the fan is in the operating state of operating at the second rotational speed, the control component controls the fan to operate at the first rotational speed in response to the temperature parameter being less than a fourth temperature threshold, wherein the fourth temperature threshold is greater than the third temperature threshold, and the first rotational speed is less than the second rotational speed. Compared with the previous embodiment, when the fan is in the working state of running at the second rotating speed, the control assembly controls the fan to run at the first rotating speed in response to the temperature parameter being smaller than the fourth temperature threshold value, due to the heat dissipation influence of the fan, the temperature parameter of the ultraviolet sterilization part at the moment is reduced, and when the temperature parameter is smaller than the fourth temperature threshold value, the ultraviolet sterilization part is in a good state and does not need to be continuously cooled.
Specifically, in order to describe the above embodiments more completely, the parameter detection component includes a temperature measurement component, and the operation parameter includes a temperature parameter.
Recording the acquired temperature parameter as Tn, firstly, judging whether an ultraviolet L ED driving circuit is started (which is equivalent to judging whether an ultraviolet sterilization part is started) or not, if not, continuously judging, if the frequency is not less than F1 and is not more than Tn and less than F2, controlling the fan to be started, enabling the fan to operate at c1, driving the ultraviolet sterilization part after the rotating speed of the fan is stabilized, if the frequency is not less than F2, starting the fan, enabling the fan to operate at c2, and driving the ultraviolet sterilization part after the rotating speed of the fan is stabilized, otherwise, directly driving the ultraviolet sterilization part to work.
If the ultraviolet L ED driving circuit is started, the judgment is continued, if Tn < F10(F10< F1), the fan is controlled to stop working, if the fan runs at c2 and Tn < F20 is detected (F1< F20< F2), the fan is changed to run at c1, and otherwise, the fan is kept to run at the current rotating speed.
Wherein c1 is less than c2, c1 is the first rotation speed, and c2 is the second rotation speed.
It can be seen that by determining the sizes of Tn and F1, F2, F10, and F20, the fans can be driven to operate at a certain rotation speed or the rotation speed of the fans can be adjusted according to the corresponding size relationship between Tn and F1, F2, F10, and F20, that is, the fan control method in different embodiments of the sterilization control device is corresponded to, obviously, the required heat dissipation of the ultraviolet sterilization part in a certain working state can also be known separately according to the size relationship between Tn and F1, F2, F10, and F20, so as to correspondingly drive the fans to dissipate heat, and the heat dissipation effect is relatively good.
Furthermore, it should be understood by those skilled in the art that, although the fan speed control manner is configured as 2-stage speed control according to the change of the parameter difference in the above embodiments, in practical applications, the speed control may be divided into 1-stage speed control, 3-stage speed control or more according to practical situations, in general, when the ultraviolet L ED lamp is used, the ultraviolet L ED lamp is generally equipped with a heat sink, for example, when the heat sink area is 4mm × 4mm, and the ultraviolet L ED lamp driving current is 80mA, the collected temperature is about 10 ℃ higher than the ambient temperature, and the maximum temperature allowed by the ultraviolet L ED lamp is generally not more than 60 ℃, and when the ambient temperature is very low, for example, when the temperature near the ultraviolet L ED lamp is below 25 ℃, the fan is not turned on, when the temperature near the ultraviolet L ED lamp is more than 30 ℃, in addition, in some cases, the area of the heat sink may be reduced for saving the installation space, and the ultraviolet L ED lamp has a higher temperature rise relative to the outside, which is more suitable for multi-stage speed control, therefore, the fan speed control manner may be adjusted according to the change of the.
