Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a block diagram of an intelligent sterilization system in a first embodiment is provided. An intelligent sterilization system 100 comprising: the intelligent sterilization system comprises an ultraviolet generator module 40 for generating ultraviolet light with a preset waveband, a sensing module 20 for sensing a human body within a safe range, a power supply module 10 for supplying electric energy to the intelligent sterilization system 100 and a main control module 30.
The main control module 30 is connected to the ultraviolet generator module 40 and the sensing module 20, respectively. The main control module 30 is used for controlling the radiation illumination mode of the intelligent sterilization system 100, and controlling the intelligent sterilization system 100 to be turned on and off according to the condition of sensing a human body by the sensing module 20. In this embodiment, the radiant illumination mode includes a continuous time mode and a dispersed time mode. When the intelligent sterilization system 100 is in the continuous time mode, the main control module 30 controls the ultraviolet generator module 40 to be in a continuous illumination state for a plurality of preset times; when the intelligent sterilization system 100 is in the distributed time mode, after the sensing module 20 senses that the human body disappears within the safe range, the main control module 30 controls the ultraviolet generator module 40 to start the illumination for a fixed time.
The continuous-time mode includes the selection of three duration modes, including: the UV light generator module 40 is in a continuous illumination state for a first predetermined duration, the UV light generator module 40 is in a continuous illumination state for a second predetermined duration, and the UV light generator module 40 is in a continuous illumination state for a third predetermined duration. The first preset time length, the second preset time length and the third preset time length are different from each other. In one embodiment, the first predetermined period of time is 5 minutes, the second predetermined period of time is 15 minutes, and the third predetermined period of time is 30 minutes.
In the distributed time mode, after the sensing module 20 senses a human body in a safe range each time, the main control module 30 controls the intelligent sterilization system 100 to be closed and in a pre-trigger state; when the sensing module 20 senses that the human body disappears within the safety range, the main control module 30 controls the ultraviolet generator module 40 to start the illumination for a fixed time. In one embodiment, the fixed duration is 15 seconds.
The dispersed time mode can also be called as a dispersed intermittent radiation mode, and the specific implementation process of the dispersed intermittent radiation mode comprises the following steps: first, the uv generator module 40 presets an intermittent time, such as 15 seconds; after the intelligent sterilization system 100 is started, when the sensing module 20 senses that a human body enters the safety range, the main control module 30 triggers an intermittent radiation working mode of the intelligent sterilization system, the sensing module 20 enters a detection stage, that is, the sensing module 20 continuously detects whether the human body still exists in the safety range, and if the preset intermittent time is exceeded, no human body sensing signal is triggered (that is, the human body still exists in the safety range), the intelligent sterilization system 100 enters a reminding mode of 30 seconds. The reminding mode specifically includes modes of sending reminding sound and light, such as flashing an indicator light and sending reminding music by a buzzer. If the human body moves slightly after being reminded, the intelligent sterilization system 100 is triggered by a new human body induction signal until the human body moves out of the safety range. The intelligent sterilization system 100 automatically returns to the detection stage of the sensing module 20 in the intermittent radiation mode, and restarts the detection of the next preset intermittent duration. If the sensing module 20 does not detect a human body within the next preset pause period from the beginning, the intelligent sterilization system 100 starts the ultraviolet generator module 40 to perform radiation sterilization. The time for the radiation sterilization may be set in advance, such as 30 seconds to 300 seconds. After the radiation sterilization is completed, the intelligent sterilization system 100 enters the next intermittent radiation operation mode. If no new human body sensing signal is triggered after the reminding mode is finished, the ultraviolet generator module 40 enters a continuous lighting state with a preset duration, and the preset duration can be programmed, for example, the duration of each time is 30 seconds to 300 seconds. After the uv generator module 40 completes the continuous illumination duration of this time, the intelligent sterilization system 100 enters the next intermittent radiation operation mode. In the dispersed time mode, the intelligent sterilization system 100 may be in a cyclic state of the intermittent radiation operation mode.
When the sensing module 20 is in the off state, any one of the radiation illumination modes uses the signal acquisition of the sensing module 20 as the first safety standard. Once the sensing module 20 collects that a human body appears in the sensing range of the sensing module 20, the ultraviolet light generator module 40 is immediately turned off; the sensing range of the sensing module 20 is more than one time larger than the set effective range of the ultraviolet radiation of the ultraviolet generator module 40.
No matter the intelligent sterilization system 100 is in the continuous time mode or the distributed time mode, when the sensing module 20 senses a human body within the safety range, the main control module 30 controls the intelligent sterilization system 100 to be turned off, so as to prevent ultraviolet rays from damaging the human body and improve the safety performance of the intelligent sterilization system 100. After the sensing module 20 senses that the human body disappears within the safety range, the continuous time mode and the discrete time mode start different forms of sterilization processes. The specific processes of the modes are as described above, and are not described herein again.
In this embodiment, the main control module 30 includes a user interaction unit 31. The user interaction unit 31 is used as a medium for the user to control the on, off and radiant illumination mode selection of the intelligent sterilization system. The specific form of the user interaction unit 31 may be a key array corresponding to different keys in different situations, a touch screen displaying different situations, or a key identified by a program algorithm. In a preferred embodiment, the user interaction unit is in the form of a key operated by a program algorithm recognition. The space of the intelligent sterilization system 100 occupied by one key is minimum, which is beneficial to the miniaturization design and modeling of the intelligent sterilization system 100. The main control module 30 recognizes different operations of the key by the user to control the on, off and selection of the radiation illumination mode of the intelligent sterilization system 100. Wherein, the different operations comprise one or more combinations of different force for touching the keys, different duration for pressing the keys and different times for pressing the keys. In a specific embodiment, the touch of the button indicates that the intelligent sterilization system 100 is activated and the radiation illumination mode is selected; pressing a key for a long time to show that the radiation illumination mode is selected to be a dispersion time mode; pressing the key for 1 time for short time indicates that the radiation illumination mode is selected to be a continuous time mode and is in a continuous illumination state with a first preset time length; pressing the key for 2 times for a short time to show that the radiation illumination mode is selected to be a continuous time mode and is in a continuous illumination state with a second preset time length; pressing the key for 3 times for short time to show that the radiation illumination mode is selected to be a continuous time mode and is in a continuous illumination state with a third preset time length; pressing the key for 4 times indicates turning off the intelligent sterilization system 100. In other embodiments, the designer of the intelligent sterilization system 100 may select other combinations of different operations according to the requirements of the software system, and the details are not repeated herein.
The intelligent sterilization system 100 provided by the embodiment of the invention has a selectable radiation illumination mode, and a user can select a continuous time mode or a dispersed time mode according to the requirements of an application scene; when the intelligent sterilization system 100 is in the continuous time mode, the ultraviolet light generator module 40 is in a continuous illumination state for a plurality of preset times; when the intelligent sterilization system 100 is in the decentralized time mode, the uv generator module 40 starts illumination for a fixed duration after the sensing module 20 senses that the human body disappears within the safe range.
Further, the intelligent sterilization system 100 in the embodiment of the present invention can also be used in a handheld manner. When the intelligent sterilization system 100 is in a handheld use state, the handheld must ensure that the radiation generated by the uv generator module 40 is not directed toward the human body. The radiant illumination pattern also includes a hand-held time of use pattern when the intelligent sterilization system 100 is in a hand-held use state. When the intelligent sterilization system 100 is in the handheld time of use mode, the ultraviolet light generator module 40 is in a continuous illumination state for an unlimited duration, and the sensing module 20 is automatically in an off state.
In a preferred embodiment, the intelligent sterilization system 100 further includes a display module (not shown in the figures). The display module is used for displaying the radiation illumination mode, the electric energy condition and the abnormal condition where the intelligent sterilization system 100 is located, and is favorable for a user to know the working state and the abnormal condition of the intelligent sterilization system 100. The display module can be in the form of a plurality of indicator lights and a display screen. The space of the intelligent sterilization system 100 occupied by the indicator light is minimum, which is beneficial to the miniaturization design and modeling of the intelligent sterilization system 100. In a preferred embodiment, the display module takes the form of a plurality of indicator lights. In one embodiment, the display module is 3 indicator lights. In the continuous time mode, 1 indicator lamp in the 3 indicator lamps is on and represents a continuous illumination state with a first preset time length; in the continuous time mode, 2 indicator lamps in the 3 indicator lamps are on and represent a continuous illumination state with a second preset time length; in the continuous time mode, 3 of the 3 indicator lights are on, representing a continuous illumination state for a third preset duration; in the dispersed time mode, 3 of the 3 indicator lights are on. When the intelligent sterilization system 100 is short of electric energy, the 3 indicator lights flash rapidly at the same time, and the flash interval is 1 second each time; when the intelligent sterilization system 100 is in a charging state, 3 indicator lights flicker intermittently at intervals of 5 seconds each time; when intelligent sterilization system 100 goes wrong, if the lamp pearl in ultraviolet generator module 40 is bad, 3 pilot lamps are interrupted the scintillation simultaneously, and the scintillation interval is 10 seconds every time. Of course, the number of the indicator lights and the connection logic relationship between the behavior of the indicator lights and the state of the intelligent sterilization system 100, and the designer of the intelligent sterilization system 100 can change according to the application requirements, and will not be described herein again.
In this embodiment, the ultraviolet light generator module 40 employs a multi-bead combination including a UVC light emitting point unit and a UVA light emitting point unit. The wavelength of a UVC wave band emitted by the UVC luminous point unit is 200-275 nm, and the UVC wave band is also called short wave sterilization ultraviolet; it has the weakest penetrating power and can not penetrate most transparent glass and plastics. The wavelength of a UVA wave band emitted by the UVA luminous point unit is 320-420 nm, and the UVA wave band is also called long-wave black spot effect ultraviolet; it has strong penetrating power and can penetrate most transparent glass and plastics. In a specific embodiment, the ultraviolet light generator module 40 may include 6 light emitting point units, i.e., 2 UVA light emitting point units and 4 UVC light emitting point units. The ultraviolet generator module 40 of the intelligent sterilization system 100 is a combination of multiple light beads, so that various types of viruses or bacteria can be killed effectively and simultaneously.
In a preferred embodiment, the intelligent sterilization system 100 further includes an additional ultraviolet light generator module 50. The additional ultraviolet generator module 50 is used to generate ultraviolet light in additional preset wavelength bands, which may be the same as or different from the preset wavelength bands of the ultraviolet generator module 40. The intelligent sterilization system 100 allows a user to effectively extend a space requiring radiation sterilization or increase the intensity of radiation sterilization according to an actual use scenario by adding the additional ultraviolet generator module 50.
In this embodiment, the sensing module 20 employs an infrared pyroelectric sensor, and the safety range is a circular area range centered on the intelligent sterilization system 100 and having a radius of at least 1.5 meters. The area of the safety range includes a circular area range centered on the intelligent sterilization system 100 and having a radius of 1.5 to 3.5 meters, depending on the acceptable degree of human damage.
The application scenarios of the intelligent sterilization system 100 provided by the embodiment of the present invention include, but are not limited to, the following scenarios: the household application scenes of an area for entering and exiting clothes, hats and shoes, an area for babies, toys and clothes, a keyboard area, a closestool, a food fresh-keeping area, an area required by mite removal and sterilization, an area in a humid environment, an area for baby excrement and sundries, a kitchen garbage area, an underwear storage area and the like are adopted; the application scenes of public environments such as closed elevators, restaurant bars, office tables, closed carriages and the like.
As shown in fig. 2, an embodiment of the present invention further provides an intelligent sterilization method using the intelligent sterilization system. The intelligent sterilization method comprises three steps, and the specific content of each step is as follows.
Step S1: and through a user interaction unit, the user starts the intelligent sterilization system and selects the radiation illumination mode in which the intelligent sterilization system is positioned.
Step S2: according to the determined radiation lighting mode, the main control module controls the ultraviolet generator module to enter a corresponding working state; when the intelligent sterilization system is in a continuous time mode, the ultraviolet light generator module is in a continuous illumination state for a plurality of preset times; when the intelligent sterilization system is in a dispersion time mode, after the sensing module senses that the human body disappears in a safe range, the ultraviolet generator module starts illumination for a fixed time.
Step S3: the sensing module is used for sensing a human body in a safety range; when the sensing module senses that a human body exists in the safety range, the sensing module sends a sensing signal to the main control module, and the main control module controls the intelligent sterilization system to be closed.
