The second preset condition is a condition of turning off the first ultraviolet lamp and the second ultraviolet lamp, and may be, for example, a sterilization duration, a user-triggered use, or a preset time point set by the user.
In order to kill bacteria in a time interval, the first preset condition is a continuous waiting time length, and the second preset condition is a continuous irradiation time length, wherein the continuous waiting time length is longer than the continuous irradiation time length;
specifically, the meeting of the first preset condition specifically includes:
when the interval duration between the starting time of the last disinfection and the current time is greater than or equal to the preset waiting duration, determining that the first preset condition is met;
the second preset condition is satisfied, and the method specifically comprises the following steps:
and when the interval time between the starting time of the last disinfection and the current time is less than the waiting time and the interval time is more than or equal to the preset irradiation time, determining that the second preset condition is met.
In addition, after one sterilization is completed each time, the current time, the continuous waiting time or the continuous irradiation time can be cleared, and then the current time, the continuous waiting time and the continuous irradiation time can be recalculated.
In actual operation, the continuous waiting time and the continuous irradiation time can be adjusted according to the actual needs of the user.
In actual operation, because the use frequency of the user is high, after a certain number of uses, a desired number of bacteria still accumulate, and in order to timely sterilize, in this embodiment, the first preset condition is the number of continuous uses, and the second preset condition is the continuous irradiation duration;
specifically, the meeting of the first preset condition specifically includes:
when the using times of unlocking by the user is greater than the preset continuous using times, a first preset condition is met;
the second preset condition is satisfied, and the method specifically comprises the following steps:
and when the sterilization starting time is longer than the preset continuous irradiation time, a second preset condition is met.
The fingerprint lock can start to count the times of using the fingerprint identification area by a user after finishing one sterilization operation, and the using times of unlocking by the user is obtained. Meanwhile, the current time can be acquired at any time node. If the fingerprint lock is sterilizing at the current time node, the sterilization duration is the duration from the starting time of the sterilization to the current time, and if the fingerprint lock is not sterilizing at the current time node, the sterilization duration is zero.
When the fingerprint using times are larger than the continuous using times, a first preset condition is met;
and when the sterilization duration is longer than the continuous irradiation duration, a second preset condition is met. And meanwhile, after the sterilization is stopped, clearing the sterilization duration and recalculating.
After one sterilization is finished each time, the fingerprint using times can be cleared, and then the fingerprint using times are recalculated and counted.
In actual operation, the number of times of using the fingerprint and the continuous irradiation time can be adjusted according to the actual needs of the user.
Compared with the prior art, the sterilization control method provided by the embodiment of the invention has the beneficial effects that: the invention can automatically control the fingerprint lock to start sterilization and disinfection after a certain time interval or a certain number of use times, thereby enabling the fingerprint lock to be cleaner and more sanitary, reducing the risk of bacterial propagation, setting the sterilization time according to the actual needs of a user, realizing automatic disinfection when the user is idle, and further improving the practicability and flexibility of the fingerprint lock.
Further, an embodiment of the present application further provides an electronic device, including: a memory, a processor and a computer program stored on the memory and executable on the processor, the processor implementing the sterilization control method as described in the above embodiments when executing the program.
Further, the present application also provides a computer-readable storage medium, which stores computer-executable instructions for causing a computer to execute the sterilization control method according to the foregoing embodiment.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
