Description

Technical Field

[0001] This case is about an electronic device and a processing method thereof, and in particular, about an electronic device and a processing method thereof that can be sterilized by ultraviolet light. Background Art

[0002] Ultraviolet C (UVC) is a low-cost, wide-range and highly efficient disinfection option. Conventional ultraviolet disinfection equipment uses UVC light. Due to its wavelength range of 280nm to 100nm, UVC light can destroy the structure of biological deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), thereby inhibiting the self-replication of organisms. UVC light has the same effect on microbial viruses or bacteria, so it can also achieve the purpose of disinfection.

[0003] The irradiation dose of UVC light will affect the sterilization ability. The irradiation dose is determined by the irradiation energy (or radiation energy) of the UVC lamp and the irradiation time. When the irradiation time of the disinfection equipment on the target object is too short or the UVC light intensity is too low, the irradiation dose will be insufficient and the replication speed of the virus (or bacteria) cannot be effectively inhibited.

[0004] Since UVC light can also cause harm to the human body, when the ultraviolet disinfection equipment is in operation, it is recommended that the user leave the space where the target object belongs. The UVC lamp will also decay over time, which will also reduce the irradiation dose. However, since the user cannot observe the UVC lamp when the disinfection equipment is running, the user cannot know whether the UVC lamp has decayed or been damaged. Summary of the invention

[0053] Sr: Disinfection signal DETAILED DESCRIPTION

[0054] Please refer to Figure 1 and Figure 2 , an electronic device for ultraviolet (UV) disinfection (hereinafter referred to as UV disinfection device 100) includes an autonomous mobile robot 110, a UV lamp group 120 and a microcontroller 130. The microcontroller 130 is electrically connected to the autonomous mobile robot 110 and the UV lamp group 120. In some embodiments, the microcontroller 130 can be implemented by one or more processing units. Each processing unit can be, but is not limited to, an embedded controller, and can also be implemented on a development board (Evaluation Board or Demo board), a digital signal processor, a central processing unit, a programmable logic controller, or any chip or circuit based on an operation instruction operation signal.

[0055] The UV lamp group 120 and the microcontroller 130 are arranged on the autonomous mobile robot 110. When performing the disinfection operation, the microcontroller 130 controls the autonomous mobile robot 110 to move at a line speed, or stops the autonomous mobile robot 110 from moving (step S240). Further, the autonomous mobile robot 110 includes a mobile mechanism, a driver and a housing. The microcontroller 130 is arranged in the housing of the autonomous mobile robot 110. The driver is coupled to the microcontroller 130, and the microcontroller 130 drives the mobile mechanism so that the mobile mechanism drives the entire UV disinfection device 100 to move. For example, when the autonomous mobile robot 110 is a vehicle using a mobile mechanism such as tires, tracks or mechanical legs, the mobile mechanism is rotatably embedded in the housing of the autonomous mobile robot 110 and is located on the side of the housing adjacent to the ground. Alternatively, when the autonomous mobile robot 110 is a flying device such as a drone, a mobile mechanism such as a propeller or a turbine is installed above, in front of or on the side of the housing.

[0056] The UV lamp group 120 includes a plurality of UV lamp tubes 121 and a driving circuit 122. The driving circuit 122 is connected between each UV lamp tube 121 and the microcontroller 130. In some embodiments, the microcontroller 130 and the driving circuit 122 may be arranged in the housing of the autonomous mobile robot 110, and the UV lamp tubes 121 are assembled on the housing of the autonomous mobile robot 110, that is, exposed on the outside of the autonomous mobile robot 110. The microcontroller 130 receives a disinfection requirement and selects an appropriate number of UV lamp tubes 121 from the UV lamp tubes 121 as operating lamp tubes according to the disinfection requirement (step S220). When performing the disinfection operation, the microcontroller 130 controls the driving circuit 122 to drive the operating lamp tube to emit deep ultraviolet light according to the disinfection requirement (step S230). In some embodiments, the operating lamp tube will emit deep ultraviolet light (hereinafter referred to as UVC light) after being enabled. It should be clear that the terms "operating lamp tube" and "UV lamp tube 121" are only used to distinguish whether it is operating (i.e., emitting light) during the disinfection operation for the convenience of description, and are not used to limit them to different lamp tubes.

[0057] In some embodiments, the aforementioned disinfection requirement is the minimum radiation dose expected to be achieved in the disinfection operation of disinfecting the target object (or space field). In other words, the radiation dose that can be provided by the UV lamp group 120 of the UV disinfection equipment 100 is expected to be relatively greater than or equal to the disinfection requirement. The formula for the radiation dose is as follows: Formula 1.

[0058] K = I * t, where

[0059] In formula 1, K is the irradiation dose (unit: mJ / cm 2 ), I is (unit: mW / cm 2 ), t is the irradiation time (unit: second).

[0060] In some embodiments, before step S220, the UV disinfection device 100 can receive disinfection requirements from an external device (e.g., a mobile phone or a personal computer). For example, the remote administrator (i.e., the user) sets the required disinfection requirements through the monitoring platform 510 or the client 520, and then transmits them to the UV disinfection device 100 via the network 170. In some embodiments, the disinfection requirements can further specify the UV lamps 121 at a specific location as operating lamps. For example, the disinfection requirements specify the UV lamps 121 on the same side as the operating lamps. Alternatively, the disinfection requirements can also specify the selection of operating lamps in a manner of spacing one UV lamp 121. In some embodiments, the UV disinfection device 100 may have a user interface to provide the user with the required disinfection requirements to be pre-set, and then stored in the UV disinfection device 100. In one example, before step S220, the user can directly enter the value of the required disinfection requirement through the keyboard on the user interface. In another example, multiple groups of disinfection requirements may be stored in the UV disinfection device 100 for the user to pre-select and set through a user interface (not shown) before step S220 .

[0061] In some embodiments, before step S220, the UV disinfection device 100 may receive a speed request 142 from an external device. For example, before step S220, the remote administrator sets the required travel speed through the monitoring platform 510 or the client 520 to generate the speed request 142, and then the speed request 142 is transmitted to the UV disinfection device 100 via the network 170 for processing. In some embodiments, the user may also use the user interface of the UV disinfection device 100 to pre-set the required travel speed, that is, input the value of the required travel speed to generate the speed request 142 to set the travel speed to this value, and then store it in the UV disinfection device 100. In one example, the user may directly input the value of the required travel speed through the keyboard on the user interface to generate the speed request 142 to set the travel speed. In another example, multiple sets of travel speed options may be stored in the UV disinfection device 100, so that the user can select a speed option through the user interface before the disinfection operation starts, so as to pre-set the travel speed.

[0062] In some embodiments, the user interface may be a touch screen, a combination of a general display screen and a plurality of physical buttons, or a combination of a touch screen and one or more physical buttons.

[0063] In some embodiments, reference Figure 5, the UV disinfection device 100 may further include a communication device 160, and the microcontroller 130 is connected to the communication device 160, so that the microcontroller 130 can be connected to the network 170 via the communication device 160, and can further communicate with the remote monitoring platform 510 or the client 520 via the network 170. In some embodiments, the communication device 160 may include a physical network interface circuit such as a wired or wireless network interface card.

[0064] In some embodiments, the UV disinfection device 100 may also have one or more storage units (not shown), and the storage units are used to store relevant software / firmware programs, information, data (such as speed requirement 142 or disinfection requirements) and combinations thereof. Among them, the microcontroller 130 may have a built-in or external storage unit. In some embodiments, each storage unit may be any type of memory, memory card, or register, and the type of storage unit is not limited here.

[0065] In some embodiments, the microcontroller 130 enables the UV disinfection device 100 (step S210), drives the autonomous mobile robot 110 according to the speed requirement 142, and enables the autonomous mobile robot 110 to start moving at a travel speed corresponding to the speed requirement 142 (step S240). The user sets the speed requirement 142 directly through the control panel of the UV disinfection device 100, or sends the speed requirement 142 to the UV disinfection device 100 from other devices. The disinfection requirement can also be input through the control panel of the UV disinfection device 100, or transmitted from other devices. Before the autonomous mobile robot 110 starts moving at the travel speed, the microcontroller 130 first selects the UV lamp 121 of the number of lamps as the operating lamp according to the disinfection requirement and the speed requirement 142 (step S220), and enables the operating lamp to emit UVC light (step S230). The number of lamps is related to the combination of the speed requirement 142 and the disinfection requirement. In other words, the microcontroller 130 adjusts the travel speed and the brightness relative to the running lamp.

[0066] When the UV disinfection device 100 moves faster, the number of lamps will be required to increase so that the irradiation dose of the operating lamps can meet the disinfection requirements. Generally speaking, the number of lamps is based on the number of operating lamps that provide the total irradiation dose closest to the disinfection requirements, and the irradiation dose is relatively greater than the disinfection requirements.

[0067] In some embodiments, the user can remotely issue a start command 140 to the UV disinfection device 100, so that the UV disinfection device 100 can be started to perform disinfection operations in an unmanned environment. Specifically, when the disinfection operation is to be performed, the microcontroller 130 can receive a disinfection signal Sr via the network 170 to enable the UV disinfection device 100 (step S210). This disinfection signal Sr carries a start command 140. After receiving the disinfection signal Sr, the microcontroller 130 determines the number of lamp tubes according to the disinfection requirements and the speed requirement 142, and selects the UV lamp tubes 121 with the number of lamp tubes as the operating lamp tubes (step S220). Then, the microcontroller 130 responds to the start command 140 to start the UV disinfection device 100, so that its autonomous mobile robot 110 moves at a travel speed corresponding to the speed requirement 142 (step S240) and causes its operating lamp tube to emit UVC light (step S230).

[0068] In some embodiments, the disinfection signal Sr may further carry a disinfection requirement 141 (or speed requirement 142) for use by the microcontroller 130 or for setting corresponding control parameters (e.g., travel speed or disinfection requirement, etc.). In other embodiments, the disinfection requirement (or travel speed) may also be pre-set as the requirement 141 or the speed requirement 142 before step S210, and the set disinfection requirement (or travel speed) may be stored in the storage unit of the UV disinfection device 100, and the microcontroller 130 may directly read the current disinfection requirement (or travel speed) from the storage unit for use after receiving the disinfection signal Sr.

[0069] In some embodiments, the UV disinfection device 100 can provide multiple groups of travel speeds to accept the processing of different speed requirements 142. In addition, the UV disinfection device 100 can provide multiple groups of disinfection requirements to accept the processing of different disinfection requirements 141.

[0070] For example, see Figures 1 to 3 , the following takes the UV disinfection device 100 having 5 sets of speed options as an example. Here, the 5 sets of speeds (step S310) are 0.1 (m / s), 0.2 (m / s), 0.3 (m / s), 0.4 (m / s) and 0.5 (m / s), and the disinfection requirements are 10 (mj / cm 2 ) and 20(mj / cm 2 ). The UV lamp group 120 has 10 UV lamp tubes 121. The values ​​and quantities of the disinfection requirement, speed requirement 142 and irradiation dose are only for illustration and are not limited thereto.

[0071] Here, the relationship between the irradiation doses that the UV disinfection device 100 can provide under different numbers of lamps and different travel speeds is as follows: Figure 4Please refer to the bar graph 400. Figures 1 to 4 At each travel speed, the UV disinfection equipment 100 emits light with different numbers of operating lamps, and five groups of irradiation doses can be measured as the number of lamps increases. Here, the number of operating lamps with different numbers of lamps are 10 operating lamps, 8 operating lamps, 6 operating lamps, 5 operating lamps, and 4 operating lamps. Figure 4 It can be seen that when the travel speed is above 0.5 m / s, even if all the UV lamps 121 are running, the UV light intensity cannot reach 20 (mj / cm 2 ) disinfection requirements (indicated by dotted lines in the figure). When the travel speed is 0.3 (m / s) and 0.4 (m / s), the UV lamps 121 need to be fully operated to achieve 20 (mj / cm 2 )’s disinfection needs.

[0072] In some embodiments, reference Figures 1 to 3 In step S220, after the UV disinfection equipment 100 receives the speed requirement 142, the microcontroller 130 first uses the speed requirement 142 or the speed option closest to and greater than or equal to the speed requirement 142 as the travel speed (step S310), and then determines the number of lamps according to the travel speed corresponding to the speed requirement 142 and the disinfection requirement (step S311), and determines whether the travel speed corresponding to the speed requirement 142 is greater than or equal to the threshold speed corresponding to the disinfection requirement. Specifically, the microcontroller 130 obtains the speed requirement 142 from the disinfection signal Sr, and reads the threshold speed corresponding to the disinfection requirement from the storage unit. Then, the microcontroller 130 confirms this speed requirement 142 according to the threshold speed corresponding to the disinfection requirement. Among them, different disinfection requirements correspond to different threshold speeds. In addition, in addition to being related to the disinfection requirement, the threshold speed is also related to the total number of UV lamps 121. In other words, the threshold speed corresponding to each disinfection requirement depends on the total number of UV lamps 121 possessed by the UV disinfection equipment 100.

[0073] The speed requirement 142 is relatively less than or equal to the threshold speed, and the microcontroller 130 sets the travel speed to the speed requirement 142 or a speed option that is closest to and greater than or equal to the speed requirement 142. The speed option is that the travel speed is set to the speed requirement 142 or the speed option that is closest to and greater than the speed requirement 142. At this time, different speed requirements 142 correspond to different numbers of lamp tubes. Therefore, the microcontroller 130 obtains the number of lamp tubes by using a corresponding table or an algorithm based on the speed requirement 142 and the disinfection requirement (steps S321-S326).

[0074] On the contrary, if the speed requirement 142 is relatively greater than the threshold speed corresponding to the disinfection requirement, the microcontroller 130 will use the threshold speed as the travel speed and specify the number of lamps as the total number of UV lamps 121 (i.e., all UV lamps 121 are used as operating lamps). In some embodiments, if the speed requirement 142 is relatively greater than or equal to the threshold speed, the microcontroller 130 will also generate and send a notification message 531 indicating that the speed is too fast and needs to be reselected to the monitoring platform 510 or the client 520, so as to re-acquire the speed requirement 142 (step S327).

[0075] For example, it is assumed that the disinfection signal Sr carries a start instruction 140 and a speed requirement 142 and the UV disinfection device 100 has set a disinfection requirement. Figure 4 , when the disinfection requirement is 20(mj / cm 2 ), the threshold speed is 0.4 (m / s). When the UV disinfection device 100 selects a travel speed of 0.4 (m / s) based on the speed requirement 142, the irradiation dose of the UV lamp group 120 when fully turned on is greater than 20 (mj / cm 2 ), while the UV lamp group 120 uses 8 operating lamps and the irradiation dose is less than 20 (mj / cm 2 ). So when the number of running lamps is "10" (pieces), it meets the requirement of 20 (mj / cm 2 ) disinfection requirement, so the number of lamps determined by the microcontroller 130 will be "10" (pieces) (step S325). Similarly, at the same speed of 0.4 (m / s), if the disinfection requirement is 10 (mj / cm 2 ), the number of lamp tubes determined by the microcontroller 130 will be "8" (pieces) (step S322).

[0076] When the travel speed of the UV disinfection device 100 is 0.5 (m / s), the irradiation dose of the 10 operating lamps is still less than 20 (mj / cm 2 ). So it does not meet the 20 (mj / cm 2 ) of the disinfection requirement. Therefore, at a speed requirement of 0.5 (m / s) 142, if the disinfection requirement is set to 20 (mj / cm 2 ), the speed requirement 142 will be considered to exceed the threshold speed. Here, the microcontroller 130 generates and sends a notification message 531 to the remote administrator (i.e., to the monitoring platform 510 or the client 520) (step S327). At this time, the microcontroller 130 will first set the travel speed to 0.5 (m / s) and designate all UV lamps 121 as operating lamps, so that the UV disinfection equipment 100 first performs the disinfection operation.

[0077] In addition, from Figure 4It can be seen that at the same speed of 0.5 (m / s), the irradiation dose of 10 running lamps is greater than 10 (mj / cm 2 ). So the disinfection requirement is 10 (mj / cm 2 ), the number of lamps determined by the microcontroller 130 will be "10" (step S326), thereby driving the autonomous mobile robot 110 to move at a speed of 0.5 (m / s) (step S240) and enabling 10 operating lamps to emit light (step S230).

[0078] Similarly, when the speed requirement 142 is 0.65 (m / s), the irradiation dose of 10 running lamps is less than 20 (mj / cm 2 ), but greater than 10(mj / cm 2 At this time, the disinfection requirement can only be selected as "10 (mj / cm 2 )” to meet the selection limit of the number of lamp tubes. In addition, since the speed requirement 142 of 0.65 (m / s) is greater than the maximum speed option of 0.6 (m / s), the microcontroller 130 will use 0.6 (m / s) as the travel speed.

[0079] Please refer to Figure 5 In some embodiments, the UV disinfection device 100 may further include a plurality of light sensors 150. These light sensors 150 are connected to the microcontroller 130 and correspond to the UV lamps 121 one by one. In other words, each UV lamp 121 is provided with a corresponding light sensor 150, and each light sensor 150 is provided at a peripheral position of the corresponding UV lamp 121. Each light sensor 150 is used to obtain the light sensing voltage value of the operating lamp at the corresponding position, and then transmit the light sensing voltage value to the microcontroller 130. In other words, each light sensor 150 senses the UVC light emitted by the corresponding UV lamp 121 and generates an electrical signal (i.e., light sensing voltage value) of the light intensity of the sensed UVC light.

[0080] After step S240, the microcontroller 130 receives the light sensing voltage value of each operating lamp (i.e., each UV lamp 121 emitting UVC light), and calculates the current irradiation dose according to the light sensing voltage value of the operating lamp and the travel speed of the corresponding speed requirement 142. Then, the microcontroller 130 compares the calculated irradiation dose with the disinfection requirement to determine whether the calculated irradiation dose meets the disinfection requirement.

[0081] If the irradiation dose is relatively less than the disinfection requirement, the microcontroller 130 generates a notification message 531 indicating that an abnormal event (such as attenuation or damage, etc.) has occurred in the operating lamp or the irradiation dose is insufficient. Here, the microcontroller 130 can store the notification message 531 in a storage unit, so that the user can access the notification message 531 stored in the UV disinfection device 100 through the monitoring platform 510 or the client 520, by connecting the UV disinfection device 100 with a computer device, or by directly operating the UV disinfection device 100, so as to confirm the execution effect of the disinfection operation.

[0082] On the contrary, if the irradiation dose is greater than or equal to the disinfection requirement, the microcontroller 130 does not generate the notification information 531 and maintains the current operating state of the UV disinfection device 100, that is, drives the autonomous mobile robot 110 to move at the traveling speed and enables the operating lamp to emit light at the same time.

[0083] In some embodiments, the UV disinfection device 100 further includes a light sensor 150 and a communication device 160. These light sensors 150 and the communication device 160 are connected to the microcontroller 130, and these light sensors 150 correspond one-to-one to the UV lamps 121. Each light sensor 150 is disposed at a peripheral position of the corresponding UV lamp 121. Each light sensor 150 obtains the light sensing voltage value of the corresponding UV lamp 121, and transmits the light sensing voltage value to the microcontroller 130.

[0084] Here, if the currently calculated irradiation dose is relatively less than the disinfection requirement, the microcontroller 130 generates a notification message 531 indicating that an abnormal event (such as attenuation or damage, etc.) has occurred in the operating lamp or the irradiation dose is insufficient, and transmits the notification message 531 to the monitoring platform 510 or the client 520 via the communication device 160 (i.e., via the network 170). On the contrary, if the irradiation dose is greater than or equal to the disinfection requirement, the microcontroller 130 does not generate the notification message 531 and maintains the current operating state of the UV disinfection device 100.

[0085] In some embodiments, when the currently calculated irradiation dose is relatively smaller than the disinfection requirement, the microcontroller 130 will also adjust the travel speed or the number of lamp tubes in real time, for example: reducing the travel speed of the autonomous mobile robot 110 or increasing the number of lamp tubes (i.e., increasing the number of UV lamps 121 serving as operating lamps), so that the UV disinfection equipment 100 moves at a slower travel speed or emits light with more UV lamps 121.

[0086] In some embodiments, after step S240, the microcontroller 130 periodically receives and records the light sensing voltage value currently measured by the light sensor 150 corresponding to each UV lamp tube 121 (or each operating lamp tube), and compares the light sensing voltage values ​​of the same UV lamp tube 121 (or the same operating lamp tube) received twice adjacently.

[0087] When the light sensing voltage value of any UV lamp 121 (or any operating lamp) decreases (i.e., the light sensing voltage value currently received is less than the light sensing voltage value received last time), the microcontroller 130 generates a notification message 531 indicating that an abnormal event (such as attenuation or damage, etc.) or insufficient irradiation dose has occurred in the operating lamp, and transmits the notification message 531 to the monitoring platform 510 or the client 520 via the communication device 160 (i.e., via the network 170). On the contrary, when the light sensing voltage values ​​of the same UV lamp 121 (or the same operating lamp) received twice in adjacent periods match each other, the microcontroller 130 does not generate the notification message 531.

[0088] In some embodiments, when the light sensing voltage value of any UV lamp 121 (or any operating lamp) decreases, the microcontroller 130 will also adjust the running speed or the number of lamps in real time.

[0089] In some embodiments, the microcontroller 130 uses a timer (not shown) to accumulate and record the operating time of each UV lamp 121 emitting UVC light (i.e., the sum of the duration of each disinfection operation). The microcontroller 130 compares the operating time of any UV lamp 121 with the threshold time to determine whether the operating time of each UV lamp 121 exceeds the threshold time.

[0090] If the running time of any UV lamp 121 is greater than or equal to the threshold time, the microcontroller 130 generates a warning notification. In addition, the microcontroller 130 can also transmit the warning notification to the monitoring platform 510 or the client 520 through the communication device 160 (i.e., via the network 170). On the contrary, if the running time of all UV lamps 121 is less than the threshold time, the microcontroller 130 does not generate a warning notification. In some embodiments, the threshold time may be related to the life of the UV lamp 121. For example: the UV disinfection device 100 can pre-set the threshold time as the preset decay time of the UV lamp 121.

[0091] In some embodiments, the monitoring platform 510 or the client 520 may be a computer device located remotely from the UV disinfection device 100. The computer device may be, for example (but not limited to), a personal computer, a server, a laptop, a tablet, or a smart phone.

[0092] In summary, the electronic device and processing method for ultraviolet disinfection of any embodiment are applied to the disinfection of space fields, and can adjust the number of UV lamps 121 emitting UVC light according to the travel speed and disinfection requirements, so that the disinfection operation meets the required disinfection requirements. In some embodiments, the electronic device for ultraviolet disinfection or the processing method for ultraviolet disinfection can also automatically adjust the travel speed or the number of UV lamps 121 emitting UVC light when the illumination of any UV lamp 121 decays. In some embodiments, the electronic device for ultraviolet disinfection or the processing method for ultraviolet disinfection can also notify the remote manager (i.e., the monitoring platform 510 or the client 520) when adjusting the travel speed or the number of lamps. In some embodiments, the electronic device for ultraviolet disinfection or the processing method for ultraviolet disinfection can also record the operating time of each UV lamp 121, and notify the remote manager when the operating time of any UV lamp 121 exceeds the threshold time. In some embodiments, the UV-disinfected electronic device or UV-disinfected processing method can also notify the remote administrator when the speed requirement 142 is greater than the threshold time corresponding to the disinfection requirement, so as to reset and provide other speed requirements 142.
