Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a schematic flow chart of a control method of an ultraviolet sterilization module in one embodiment of the invention. The method of fig. 1 may be applied to an ultraviolet sterilization apparatus, which may include a plurality of independently controlled ultraviolet sterilization modules, and which may be applied to an air conditioner indoor unit, a fresh air system, an air purification system, and the like. The method comprises the following steps:
and S102, determining the starting number of the ultraviolet sterilization modules according to the current environment temperature.
Since the sterilization performance of the ultraviolet sterilization module is greatly affected by the ambient temperature, the time required for achieving the same expected sterilization effect at different ambient temperatures is different. The ultraviolet sterilization device in the embodiment comprises a plurality of independently controlled ultraviolet sterilization modules, so that the ultraviolet sterilization modules in different quantities can be controlled to work at different environmental temperatures, the same expected sterilization effect is achieved, and the sterilization rate requirement is met.
After the sterilization function is started, the current environment temperature can be obtained through equipment such as a sensor, and the starting number of the ultraviolet sterilization modules is determined according to the current environment temperature. Generally, the higher the current ambient temperature is, the greater the number of uv sterilization modules that need to be turned on. Optionally, a corresponding relationship between the current ambient temperature and the number of the ultraviolet sterilization modules to be turned on is preset, and the number of the ultraviolet sterilization modules to be turned on can be determined by inquiring the corresponding relationship.
And S104, controlling to start the target ultraviolet sterilization modules with the starting number according to the starting number and the corresponding residual service life of each ultraviolet sterilization module.
And the residual service life corresponding to the target ultraviolet sterilization module is longer than that corresponding to other ultraviolet sterilization modules. For a plurality of ultraviolet sterilization modules, the starting number is the starting number obtained by the steps, wherein the residual service life is longer.
In one embodiment, which uv sterilization modules are preferentially activated may be determined in a sorted manner, optionally performed as follows:
a1, sequencing the residual service lives corresponding to the ultraviolet sterilization modules from large to small to obtain a sequencing result.
And A2, controlling to start the target ultraviolet sterilization module, wherein the target ultraviolet sterilization module comprises the ultraviolet sterilization modules with the previous opening number in the sequencing result. After the rest service life is sequenced from large to small, the ultraviolet sterilization modules with the corresponding number of the starting numbers are started according to the sequence from large to small.
In another embodiment, which uv sterilization modules are preferentially activated may be determined by screening, optionally performed as follows:
and B1, screening the maximum value of the residual service life corresponding to each ultraviolet sterilization module to obtain the target ultraviolet sterilization module. The target ultraviolet sterilization module comprises ultraviolet sterilization modules with the maximum residual service life and the maximum starting number. Firstly, screening out the ultraviolet sterilization modules with the largest residual service life from all the ultraviolet sterilization modules, and taking the ultraviolet sterilization modules as target ultraviolet sterilization modules; screening out the ultraviolet sterilization modules with the largest residual service life from all the residual ultraviolet sterilization modules, and continuously taking the ultraviolet sterilization modules as target ultraviolet sterilization modules; and screening for multiple times until the ultraviolet sterilization modules with the number corresponding to the starting number are obtained.
And B2, controlling to start the target ultraviolet sterilization module.
In the actual operation process of the ultraviolet sterilization device, the ultraviolet sterilization modules are not simultaneously opened and closed, the residual service lives of the ultraviolet sterilization modules are different, the ultraviolet sterilization module with the longer residual service life is started as the target ultraviolet sterilization module, the residual service life of the ultraviolet sterilization modules can be balanced, and the service life uniformity of the ultraviolet sterilization modules is improved.
Generally, all ultraviolet sterilization modules need to be integrally installed and detached, if the difference of the residual service lives of the ultraviolet sterilization modules is too large, when the residual service life of a certain ultraviolet sterilization module is zero, the residual service lives of other ultraviolet sterilization modules are possibly long, the residual service lives of the ultraviolet sterilization modules are integrally replaced at the moment, the sterilization service life is wasted, and if the ultraviolet sterilization modules are not replaced, the residual service lives of the ultraviolet sterilization modules are zero, so that the sterilization function cannot be achieved. In this embodiment, by controlling the ultraviolet sterilization modules with longer remaining service lives to be started preferentially, the approximate equal life of each ultraviolet sterilization module can be realized.
Specifically, the remaining service life may be a difference between the design life and the accumulated opening time, or the remaining service life may be a ratio of the difference to the design life. It should be noted that the time length of each operation of each ultraviolet sterilization module may be recorded, so as to obtain the accumulated starting time length of each ultraviolet sterilization module. The method can further comprise the following steps: recording the accumulated starting time of the ultraviolet sterilization module; and then, determining the residual service life of the ultraviolet sterilization module according to the accumulated starting time of the ultraviolet sterilization module and the design life of the ultraviolet sterilization module.
According to the control method of the ultraviolet sterilization module, the starting number of the ultraviolet sterilization modules can be determined according to the current environment temperature, and the ultraviolet sterilization modules with longer residual service life are controlled to be started preferentially, so that the sterilization rate requirements under different temperature conditions are met, the sterilization life of the ultraviolet sterilization modules is not wasted, and the service life consistency of each ultraviolet sterilization module is improved.
Considering that the longer the accumulated opening time of the ultraviolet sterilization module is, the worse the sterilization effect is, the opening time needs to be correspondingly increased, and the opening time can be determined based on the remaining service life of the ultraviolet sterilization module. Optionally, the following is performed:
firstly, determining the starting time of the target ultraviolet sterilization module according to the corresponding residual service life of the target ultraviolet sterilization module. The starting time length is inversely related to the remaining service life corresponding to the target ultraviolet sterilization module, the starting time length is shorter as the remaining service life corresponding to the target ultraviolet sterilization module is longer, and the starting time length is longer as the remaining service life corresponding to the target ultraviolet sterilization module is shorter.
It can be understood that the starting time duration of each target ultraviolet sterilization module can be determined based on the remaining service life corresponding to the target ultraviolet sterilization module, that is, the starting time duration of each target ultraviolet sterilization module can be different; the starting time length of each target ultraviolet sterilization module can be determined based on the minimum residual service life in the residual service lives corresponding to the target ultraviolet sterilization modules, namely the starting time length of each target ultraviolet sterilization module is determined based on the minimum residual service life, and the starting time lengths of the target ultraviolet sterilization modules are the same; similarly, the starting time length of each target ultraviolet sterilization module can be determined based on the maximum remaining service life or the average remaining service life of the remaining service lives corresponding to the target ultraviolet sterilization modules, and the starting time lengths of the target ultraviolet sterilization modules are the same.
And secondly, controlling the starting number of the target ultraviolet sterilization modules to start and operate for corresponding starting duration. The target ultraviolet sterilization modules with the number corresponding to the starting number can be controlled to be started until the running time of each target ultraviolet sterilization module reaches the starting time.
On the basis of the method, the embodiment also provides the functions of monitoring the service life in real time and prompting the replacement, and if the residual service life of the ultraviolet sterilization module is less than or equal to zero, all the ultraviolet sterilization modules are controlled to be started, and/or replacement prompt information is output. When the remaining service life is less than or equal to zero, the accumulated starting time of the ultraviolet sterilization module is equal to or longer than the design life of the ultraviolet sterilization module, and at the moment, in order to improve the sterilization effect as much as possible, all the ultraviolet sterilization modules can be controlled to be started, and/or prompt information that the ultraviolet sterilization modules need to be replaced is output.
In order to make the user have visual understanding of the service life of the ultraviolet sterilization module, the residual service life can be displayed when the sterilization function is turned on or turned off. It can be understood that the remaining service life may be one remaining service life corresponding to all the ultraviolet sterilization modules, or may be a plurality of remaining service lives corresponding to each of the ultraviolet sterilization modules. The remaining service life corresponding to all the ultraviolet sterilization modules may be one of a minimum remaining service life, a maximum remaining service life or an average remaining service life corresponding to all the ultraviolet sterilization modules.
