Abstract
Description
Technical Field
[0001] This invention relates to the field of air disinfection technology, and more particularly to a disinfection system. Background Technology
[0002] Viruses and bacteria in the air can cause multi-organ diseases, such as respiratory diseases, cerebrovascular diseases, and nasal inflammation. People who live in environments with low air pressure, poor air circulation, and relatively enclosed spaces are more susceptible to the spread of diseases caused by airborne bacteria and viruses. Accordingly, systems and devices for purifying and disinfecting the air have emerged.
[0003] For example, patent CN115262715A discloses a high-efficiency ventilation and disinfection system and method for mobile epidemic prevention toilets. The disinfection system incorporates novel oxidation disinfection technology and an intelligent control module, effectively improving toilet maintenance efficiency and reducing chemical and energy consumption. The atomized disinfection mode and bidirectional ventilation reduce chemical residues, ensuring hygiene while minimizing secondary pollution and carbon emissions to the environment and human body. The disinfection method provided by this patent utilizes atomized spraying of a green oxidant coupled with ultraviolet irradiation activation technology to generate a large number of high-energy photons, strong oxidizing free radicals, and their derived active substances to purify and disinfect the surfaces of toilet items and aerosols. Combined with active indoor air circulation and outdoor ventilation, it effectively eliminates pathogenic microorganisms in the air.
[0004] Patent CN114177336A discloses a disinfection method, which includes receiving a disinfection command and, based on the command, preparing chlorine dioxide aerosol for disinfection; then, delivering the prepared chlorine dioxide aerosol to the space to be disinfected through a ventilation device; during the disinfection process, detecting the concentration of chlorine dioxide gas in real time and obtaining a first concentration value; then determining whether the first concentration value reaches a preset first concentration threshold; if so, outputting timing information to time the duration of the first concentration threshold; then determining whether the first duration is greater than a preset first duration threshold; if so, outputting a stop command; and stopping the preparation of chlorine dioxide aerosol based on the stop command.
[0005] Existing technologies primarily employ air purification and the spraying of gaseous disinfectants to eliminate pathogenic microorganisms in the air. However, when using a ventilation and disinfection system, such as that described in patent CN115262715A, to disinfect indoor environments, the system controls ventilation and disinfection equipment operation by detecting whether people are present and monitoring air quality. This method lacks validation of the purification and disinfection equipment, relying on experience and intuition during implementation. There is a possibility of secondary pollution at the air outlets, and the exhausted air lacks sterilization treatment, potentially leading to cross-infection. Patent CN115262715A utilizes chlorine dioxide gas for air disinfection. While chlorine dioxide is harmless to humans and is an internationally recognized safe and non-toxic green disinfectant, it is a gas with a strong, irritating odor. Contact with chlorine dioxide can cause eye and respiratory irritation; therefore, chlorine dioxide is unsuitable for disinfecting areas with human activity.
[0006] This invention provides a disinfection system to solve the problems existing in the prior art.
[0007] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention
[0008] To address the shortcomings of existing technologies, this invention provides a disinfection system. The disinfection system includes at least a management platform, an air disinfection device, and a gas detection device. Preferably, the management platform is electrically connected to the air disinfection device and the gas detection device via wired or wireless means, respectively. The air disinfection device disperses a disinfectant into the air to disinfect it. The gas detection device detects the concentration of the disinfectant in the air and transmits the detection data to the management platform. Preferably, in response to the receipt of the detection data, the management platform determines the virus survival rate based on the concentration of the disinfectant in the air; and the management platform generates control commands to adjust the operating parameters of the air disinfection device based on the virus survival rate and sends them to the air disinfection device. Preferably, the operating parameters include at least the disinfectant dispersal efficiency of the air disinfection device.
[0009] Preferably, the air disinfection device and the gas detection device in this invention are designed as separate units. The gas detection device can detect the concentration of disinfectant in the area covered by the air disinfection device. The management platform can obtain the detection data from the gas detection device to determine the disinfection effect of the air disinfection device, thereby verifying the disinfection performance of the air disinfection device.
[0010] According to a preferred embodiment, when the air disinfection device establishes a communication connection with the management platform, the management platform at least obtains the type of disinfectant used by the air disinfection device, and the relationship curve between the disinfectant concentration and the virus survival rate. The management platform sets a disinfectant threshold based on the relationship curve to determine the disinfection effect and / or operating status of the air disinfection device.
[0011] Preferably, after obtaining the type of disinfectant used in the air disinfection device and the relationship curve between the disinfectant concentration and the virus survival rate, the management platform can determine the virus survival rate by detecting the concentration of the disinfectant. This eliminates the need to sample and test the air in the disinfection environment to determine the content of microorganisms in the air, thereby simplifying the detection of the disinfection effect.
[0012] According to a preferred embodiment, the disinfectant threshold includes at least a first threshold and a second threshold corresponding to a disinfectant concentration that causes the virus survival rate to be lower than a preset value. Preferably, the virus survival rate at the first threshold is lower than the virus survival rate at the second threshold. The management platform uses the gas detection device to detect the disinfectant concentration in the air and controls the air disinfection device to switch its operating state according to the disinfectant concentration and the disinfectant threshold.
[0013] According to a preferred embodiment, the air disinfection device operates in at least three states: a first state of standby, a second state of dispersing disinfectant at a first spraying efficiency, and a third state of dispersing disinfectant at a second spraying efficiency. Preferably, the second spraying efficiency is higher than the first spraying efficiency. The management platform controls the switching of the air disinfection device's operating states according to preset rules. Preferably, the preset rules include at least the correspondence between the operating states of the air disinfection device, the disinfectant threshold, and the disinfectant concentration detected by the gas detection device.
[0014] According to a preferred embodiment, the preset rules include at least the following: when the disinfectant concentration detected by the gas detection device exceeds the first threshold, the management platform controls the air disinfection device to enter a first working state; when the disinfectant concentration detected by the gas detection device is lower than the second threshold, the management platform controls the air disinfection device to enter a third working state; and when the disinfectant concentration detected by the gas detection device is between the first threshold and the second threshold, the management platform controls the air disinfection device to enter a second working state.
[0015] According to a preferred embodiment, the management platform generates a control command to adjust the operating parameters of the air disinfection device and sends it to the air disinfection device. In response to receiving the control command, the air disinfection device adjusts its operating parameters to switch operating states. Preferably, the operating parameters further include the duration of the operating state.
[0016] Preferably, the first threshold can be the disinfectant concentration required to achieve the virus survival rate for disinfection. Preferably, when the disinfection system disinfects the environment in the disinfection area, the migration or dissipation of the disinfectant dispersed by the air disinfection device takes time, and a specific disinfectant concentration and disinfection duration are required to achieve the disinfection purpose. Therefore, the air disinfection device can stop dispersing the disinfectant after the concentration in the air exceeds the first threshold. When the disinfectant concentration drops below the first threshold due to migration or dissipation, the air disinfection device can respond to a control command sent by the management platform and disperse the disinfectant again to bring the concentration back above the first threshold, thus ensuring that the disinfectant concentration and disinfection duration meet the disinfection purpose while avoiding excessive use and waste of disinfectant.
[0017] According to a preferred embodiment, after the air disinfection device switches to the second or third working state and the working state continues for the specified duration, the air disinfection device enters the first working state.
[0018] Preferably, after the air disinfection device switches to the second or third working state and the working state continues for a certain period of time, the disinfectant concentration in the area covered by the air disinfection device exceeds the first threshold, the disinfection effect of the disinfectant tends to be saturated, the air disinfection device does not need to continue to spread disinfectant, and the air disinfection device enters the first working state to avoid wasting disinfectant.
[0019] According to a preferred embodiment, if the management platform does not send a control command to the air disinfection device, the air disinfection device enters a first operating state within a first time period and operates in the first operating state for a first time period. Then, the air disinfection device enters a second operating state within a second time period. After operating in the second operating state for a second time period, the air disinfection device returns to the first operating state and operates in the first operating state for a first time period until the management platform sends a control command to the air disinfection device. Preferably, the first time period is longer than the second time period.
[0020] Since disinfectants require a certain amount of time to dissipate in the air, preferably, when the disinfectant concentration in the area covered by the air disinfection device exceeds a first threshold, the air disinfection device cycles between a first operating state and a second operating state to maintain the disinfectant concentration in the area covered by the air disinfection device above the first threshold. Preferably, when the disinfectant concentration in the area covered by the air disinfection device exceeds the first threshold and the air disinfection device is in the first operating state, the air disinfection device enters the second operating state before the disinfectant concentration decreases to the first threshold to maintain the disinfectant concentration in the area covered by the air disinfection device above the first threshold.
[0021] The present invention also provides a disinfection method. The disinfection method includes at least:
[0022] Determine the type of disinfectant and obtain the relationship curve between the concentration of the disinfectant and the virus survival rate;
[0023] Using an air disinfection device to release disinfectant into the air;
[0024] The concentration of disinfectant in the air is detected using a gas detection device;
[0025] The virus survival rate was determined based on the relationship curve and the detected concentration of disinfectant.
[0026] The operating parameters of the air disinfection device are adjusted according to the determined virus survival rate, wherein the operating parameters include at least the disinfectant dispersal efficiency of the air disinfection device.
[0027] The present invention also provides a storage medium. The storage medium stores a program, which is executed by a processor to perform the disinfection method provided by the present invention. Attached Figure Description

[0031] 100: Disinfection system; 110: Management platform; 120: Air disinfection device; 130: Gas detection device. Detailed Implementation
[0032] The following is in conjunction with the appendix Figure 1 and 2 Please provide a detailed explanation.
[0033] Example 1
[0034] This embodiment provides a disinfection system 100. See also... Figure 1 Preferably, the disinfection system 100 includes at least a management platform 110, an air disinfection device 120, and a gas detection device 130. Preferably, the management platform 110 is electrically connected to the air disinfection device 120 and the gas detection device 130 via wired or wireless means, respectively. The air disinfection device 120 is used to disperse disinfectant into the air to disinfect it. The gas detection device 130 is used to detect the concentration of disinfectant in the air and transmit the detection data to the management platform 110.
[0035] Preferably, in response to the receipt of detection data, the management platform 110 determines the virus survival rate based on the concentration of disinfectant in the air; and the management platform 110 generates control instructions to adjust the operating parameters of the air disinfection device 120 based on the virus survival rate and sends them to the air disinfection device 120. Preferably, the operating parameters include at least the disinfectant dispersal efficiency of the air disinfection device 120.
[0036] Preferably, when the air disinfection device 120 establishes a communication connection with the management platform 110, the management platform 110 at least obtains the type of disinfectant used by the air disinfection device 120, and the relationship curve between the concentration of the disinfectant and the virus survival rate. The management platform 110 sets a disinfectant threshold based on the relationship curve to determine the disinfection effect and / or operating status of the air disinfection device 120.
[0037] Preferably, the disinfectant used in the air disinfection device 120 can be nano-water ions, negative ions, or other non-toxic bactericides. Preferably, in this embodiment, nano-water ions are used as the disinfectant, and the air disinfection device 120 can be a nano-water ion generator. Preferably, the nano-water ions generated by the nano-water ion generator are encapsulated in water and do not easily combine with oxygen and nitrogen in the air, thus allowing them to exist in the air for a long time. Furthermore, the water-encapsulated nano-water ions can easily adhere to the surface of various bacteria, allowing the large number of hydroxyl radicals they contain to fully contact the bacteria and extract hydrogen ions from them. The hydroxyl radicals combine with the hydrogen ions to form water, causing various bacteria to lose their activity, thereby achieving the elimination of bacteria.
[0038] Preferably, the disinfectant threshold may include a first threshold and a second threshold corresponding to the disinfectant concentration that causes the virus survival rate to be below a preset value. Preferably, the virus survival rate at the first threshold is lower than the virus survival rate at the second threshold. The management platform 110 uses the gas detection device 130 to detect the disinfectant concentration in the air and controls the air disinfection device 120 to switch its operating state according to the disinfectant concentration and the disinfectant threshold. Preferably, the virus survival rate at the first threshold is 0.1%, and the virus survival rate at the second threshold is 0.5%.
[0039] Preferably, the air disinfection device 120 has at least three operating states: a first operating state of standby, a second operating state of dispersing disinfectant at a first spraying efficiency, and a third operating state of dispersing disinfectant at a second spraying efficiency. Preferably, the second spraying efficiency is higher than the first spraying efficiency. The management platform 110 controls the switching of the operating states of the air disinfection device 120 according to preset rules. Preferably, the preset rules include at least the correspondence between the operating states of the air disinfection device 120, the disinfectant threshold, and the disinfectant concentration detected by the gas detection device 130.
[0040] Preferably, the preset rules include at least the following: when the disinfectant concentration detected by the gas detection device 130 exceeds a first threshold, the management platform 110 controls the air disinfection device 120 to enter a first working state; when the disinfectant concentration detected by the gas detection device 130 is lower than a second threshold, the management platform 110 controls the air disinfection device 120 to enter a third working state; and when the disinfectant concentration detected by the gas detection device 130 is between the first and second thresholds, the management platform 110 controls the air disinfection device 120 to enter a second working state.
[0041] Preferably, the management platform 110 generates a control command to adjust the operating parameters of the air sterilizer 120 and sends it to the air sterilizer 120. In response to receiving the control command, the air sterilizer 120 adjusts its operating parameters to switch operating states. Preferably, the operating parameters also include the duration of the operating state.
[0042] Preferably, if the management platform 110 does not send a control command to the air sterilization device 120, the air sterilization device 120 enters a first working state within a first time period and operates in the first working state for a first time period. Then, the air sterilization device 120 enters a second working state within a second time period. After operating in the second working state for a second time period, the air sterilization device 120 returns to the first working state and operates in the first working state for a first time period until the management platform 110 sends a control command to the air sterilization device 120. Preferably, the first time period is longer than the second time period.
[0043] Preferably, when the disinfectant concentration in the area covered by the air disinfection device 120 exceeds a first threshold, the air disinfection device 120 cycles between a first operating state and a second operating state to maintain the disinfectant concentration in the area covered by the air disinfection device 120 above the first threshold. Preferably, when the concentration of nano-water ions is at the first threshold, it needs to be maintained for 120 minutes to disinfect bacteria in the disinfection area.
[0044] Preferably, in this invention, the air disinfection device 120 and the gas detection device 130 are designed separately. The gas detection device 130 can detect the concentration of disinfectant in the area covered by the air disinfection device 120. The management platform 110 can determine the disinfection effect of the air disinfection device 120 by acquiring the detection data from the gas detection device 130, thereby verifying the disinfection performance of the air disinfection device 120.
[0045] Preferably, after the management platform 110 obtains the type of disinfectant used in the air disinfection device 120 and the relationship curve between the concentration of the disinfectant and the virus survival rate, it can determine the virus survival rate by detecting the concentration of the disinfectant. This eliminates the need to sample and test the air in the disinfection environment to determine the content of microorganisms in the air, thereby simplifying the detection of the disinfection effect.
[0046] Preferably, the first threshold can be the disinfectant concentration required to achieve the virus survival rate for disinfection. Preferably, when the disinfection system 100 disinfects the environment in the disinfection area, the disinfectant dispersed by the air disinfection device 120 takes a certain amount of time to migrate or dissipate in the air. Furthermore, when using disinfectant for disinfection, a specific disinfectant concentration and a specific disinfection duration are required to achieve the disinfection objective. Therefore, the air disinfection device 120 can stop dispersing disinfectant after the concentration in the air exceeds the first threshold. When the disinfectant concentration decreases below the first threshold due to migration or dissipation, the air disinfection device 120 can respond to a control command sent by the management platform 110 and disperse disinfectant again to bring the disinfectant concentration in the air back above the first threshold, thus ensuring that the disinfectant concentration and disinfection duration meet the disinfection objective while avoiding excessive use and waste of disinfectant.
[0047] Preferably, after switching to the second or third working state and after the working state has been in operation for a certain duration, the air disinfection device 120 enters the first working state.
[0048] Preferably, after the air disinfection device 120 switches to the second or third working state and has been in the working state for a certain period of time, the concentration of disinfectant in the area covered by the air disinfection device 120 exceeds the first threshold, the disinfection effect of the disinfectant tends to be saturated, the air disinfection device 120 does not need to continue to spread disinfectant, and the air disinfection device 120 enters the first working state to avoid waste of disinfectant.
[0049] Example 2
[0050] This embodiment is a further improvement on Embodiment 1, and repeated content will not be described again. Where there is no conflict or contradiction, the whole and / or parts of the preferred embodiments of other embodiments can be used as supplements to this embodiment.
[0051] Under natural conditions, after the air disinfection device 120 disperses the disinfectant into the disinfection environment, the disinfectant concentration detected by the gas detection device 130 decreases as the distance between the gas detection device 130 and the air disinfection device 120 increases. Preferably, in the case of the air disinfection device 120 dispersing the disinfectant, this embodiment can move the gas detection device 130 away from the air disinfection device 120 and collect the disinfectant concentration detected during the movement. Preferably, this embodiment can compare the disinfectant concentration detected by the gas detection device 130 during the movement with the disinfectant concentration during effective disinfection to determine the effective disinfection range of a circular air disinfection device 120.
[0052] Preferably, in order to increase the effective disinfection range, the air disinfection device 120 is usually equipped with ventilation equipment or works in conjunction with existing ventilation equipment, so that the airflow generated by the ventilation equipment can promote the migration of disinfectant in the air, thereby increasing the effective disinfection range of the air disinfection device 120. However, while the airflow generated by the ventilation equipment promotes the migration of disinfectant in the air, it also promotes the migration of bacteria in the air, which may affect the disinfection efficiency of the disinfection system. Especially when disinfecting environments that do not have sealed conditions, using ventilation equipment to increase the effective disinfection range of the air disinfection device 120 may actually promote the spread of bacteria and increase the risk of infection for the population.
[0053] Preferably, when disinfecting environments that do not have sealed conditions, such as restaurants, indoor halls, and office building corridors, existing technologies usually use manual spraying of disinfectants. However, the disinfection process itself has a certain degree of infectivity and is harmful to the human body. When using air disinfection devices 120 for disinfection, since the coverage of a single air disinfection device 120 is limited, a large number of air disinfection devices 120 are usually required for disinfection, which makes the disinfection cost high.
[0054] To address the shortcomings of existing technologies, this embodiment provides a disinfection system 100. Preferably, the disinfection system 100 provided in this embodiment may include a management platform 110, several air disinfection devices 120, and several gas detection devices 130. The disinfection system 100 provided in this embodiment can be used for routine disinfection of high-risk environments such as hospitals.
[0055] Preferably, the management platform 110 can be electrically connected to the air disinfection device 120 and the gas detection device 130 via wired or wireless means, respectively. Preferably, the gas detection device 130 can be installed in environments requiring routine disinfection. The air disinfection device 120 can be mounted on a mobile platform such as a navigation robot or a cleaning robot. Preferably, the management platform 110 can detect the concentration of disinfectant in various environments within the hospital that require routine disinfection through the gas detection devices 130 installed therein.
[0056] Preferably, when the disinfectant concentration in the area where the gas detection device 130 is located is lower than the threshold, the management platform 110 generates a control command to disinfect the area where the gas detection device 130 is located and sends it to the air disinfection device 120. In response to the receipt of the control command, the air disinfection device 120 moves to the area where the gas detection device 130 is located using a movable platform and releases disinfectant, thereby completing the disinfection.
[0057] Preferably, in this embodiment, the area requiring routine disinfection can be divided into several sub-areas based on the effective detection range of the gas detection device 130, and a separate gas detection device 130 can be installed in each sub-area. Preferably, the management platform 110 can obtain the disinfectant concentration in each sub-area through each gas detection device 130. Preferably, when the disinfectant concentration in a certain sub-area is lower than a threshold, the management platform 110 can send a command to the air disinfection device 120, causing the air disinfection device 120 to move to the corresponding sub-area to disperse disinfectant for disinfection, thereby achieving precise disinfection of the area requiring routine disinfection and avoiding excessive use and waste of disinfectant. Preferably, the disinfectant used by the air disinfection device 120 can be nano-water ions. Since nano-water ions are non-toxic and non-irritating to the human body, the disinfection system 100 can perform disinfection even when there is human activity, thereby ensuring the efficiency of routine disinfection while avoiding the irritation to the human body caused by disinfectants such as disinfectant alcohol and chlorine dioxide.
[0058] Taking a hospital waiting hall as an example, specifically, in this embodiment, the hospital waiting hall can be divided into several sub-areas according to the effective detection range of the gas detection device 130, and a gas detection device 130 can be set up separately in each sub-area. Preferably, the management platform 110 can number the divided sub-areas by obtaining the architectural drawings of the hospital waiting hall and the installation drawings of the gas detection device 130. Preferably, the management platform 110 can communicate with the gas detection device 130 and the air disinfection device 120 through wireless communication technologies such as WiFi. The gas detection device 130 sends the collected disinfectant concentration to the management platform 110 in real time. When the disinfectant concentration value received by the management platform 110 is lower than the threshold, the management platform 110 can send an instruction to the air disinfection device 120 to disinfect the sub-area where the gas detection device 130 that collected the disinfectant concentration value is located. Preferably, after receiving the instruction, the air disinfection device 120 moves to the corresponding sub-area through a mobile platform to spread disinfectant to disinfect the sub-area. Preferably, the instructions sent from the management platform 110 to the gas detection device 130 include at least the number representing the sub-area and the amount of disinfectant sprayed.
[0059] Preferably, when the disinfectant concentration values in multiple sub-areas are below a threshold, the management platform 110 can send an instruction to the air disinfection device 120, causing the air disinfection device 120 to move to the corresponding sub-areas to disperse disinfectant for disinfection. Preferably, when the disinfectant concentration values in multiple sub-areas are below the threshold, the instruction sent by the management platform 110 to the air disinfection device 120 can be a moving spraying strategy planned by the management platform 110 based on the location of the air disinfection device 120, the location of each area to be disinfected, and the amount of disinfectant sprayed in each area to be disinfected.
[0060] Preferably, the movement strategy may include the movement route of the air disinfection device 120, and the movement route connects each area to be disinfected as nodes.
[0061] Preferably, when planning the mobile spraying strategy, the management platform 110 determines the starting point of the mobile spraying route based on the location of the air disinfection device 120. Preferably, the air disinfection device 120 moves along the mobile route to pass through each node, and disinfects the area to be disinfected corresponding to that node after reaching it.
[0062] Preferably, the sequence of nodes on the moving route can be based on the moving distance between nodes as the first condition and the amount of disinfectant sprayed as the second condition, arranged in order of increasing moving distance between nodes and decreasing amount of disinfectant sprayed. This allows the air disinfection device 120 to complete the disinfection of each area to be disinfected in the shortest possible time, and can prioritize replenishing disinfectant in sub-areas with large differences between disinfectant concentration and threshold, thereby ensuring that the disinfectant concentration in the areas to be disinfected is always at a high level to ensure the disinfection effect.
[0063] Example 3
[0064] This embodiment is a further improvement on Embodiments 1 and 2, and repeated content will not be described again. Where there is no conflict or contradiction, the whole and / or parts of the preferred embodiments of other embodiments can be used as supplements to this embodiment.
[0065] According to a preferred embodiment, the gas detection device 130 can be a smart detection terminal worn by medical personnel. Preferably, the smart detection terminal can be a smart mobile device connected to a gas detection module; optionally, usable smart mobile devices include mobile phones, tablets, etc. Preferably, the gas detection module connected to the smart mobile device can detect disinfectant concentrations within a certain range.
[0066] Preferably, the smart detection terminal worn by medical personnel can detect the disinfectant concentration in the area where the medical personnel are located. Preferably, when detecting the disinfectant concentration, the smart detection terminal can transmit the collected disinfectant concentration and the corresponding spatial location to the management platform 110. In response to receiving the data transmitted by the smart detection terminal, the management platform 110 can determine the disinfectant concentration at the spatial location detected by the smart detection terminal.
[0067] Preferably, when the disinfectant concentration at a spatial location detected by the intelligent detection terminal is lower than a threshold, the management platform 110 can generate a control command to disinfect that spatial location and send it to the air disinfection device 120. In response to receiving the control command, the air disinfection device 120 uses its movable platform to move to the spatial location and release the disinfectant, thereby completing the disinfection. Preferably, when the disinfectant concentration at a spatial location detected by the intelligent detection terminal is lower than a threshold, the management platform 110 can generate a control command to disinfect that spatial location and send it to the air disinfection device 120 to disinfect that spatial location.
[0068] For indoor disinfection environments, after the air disinfection device 120 sprays disinfectant into the disinfection environment, the concentration of the disinfectant decreases with increasing distance from the spray point, resulting in a weakened disinfection effect. Furthermore, the presence of obstructions in the indoor disinfection environment that hinder the migration of the disinfectant in the air further reduces the disinfection effectiveness of the air disinfection device 120. Preferably, to ensure disinfection effectiveness, the disinfection system 100 can increase the effective coverage area of the disinfectant in the indoor disinfection environment by increasing the amount of disinfectant sprayed by the air disinfection device 120 and / or increasing the mobility of the air disinfection device 120.
[0069] Preferably, the management platform 110 can determine the key areas for disinfection by recording the movement trajectory of the smart detection terminals worn by medical personnel. Preferably, areas where the movement trajectories of the smart detection terminals overlap or where the smart detection terminals linger for extended periods are identified as hotspot locations.
[0070] Preferably, the intelligent detection terminal uploads its location information to the management platform 110 in real time, enabling the management platform 110 to obtain the movement trajectory of the intelligent detection terminal through trajectory tracking algorithms combined with pre-stored architectural drawings. Preferably, the management platform 110 can obtain hotspot locations through an intelligent algorithm. The principle of this intelligent algorithm is as follows: Each floor's indoor space is divided into several grid areas according to the architectural drawings; a positive integer number of samples are obtained, each sample containing several location data corresponding to a movement trajectory of the intelligent detection terminal in the indoor space; a density-based clustering algorithm is used to cluster the obtained samples to obtain a class representing the number of location data belonging to different movement trajectories in a single grid area; the hotspot location is the actual location in the indoor space of the grid area represented by the class where the number of location data belonging to different movement trajectories in the clustering algorithm exceeds a preset threshold.
[0071] Preferably, the disinfection system 100 determines the key areas and hot spots for disinfection by tracking the movement of the intelligent detection terminal, thereby accurately locating the concentrated points of disinfection in the disinfection environment. This allows the air disinfection device 120 to accurately identify the concentrated points of disinfection when spraying disinfectant, thus achieving efficient, economical, and accurate disinfection.
[0072] Preferably, when disinfecting the indoor environment of a hospital, the indoor environment can be divided into a first environment and a second environment. The first environment can be an environment where medical staff stay for a long time or frequently enter and exit due to performing medical procedures, while the second environment can be an environment that meets the needs of daily personnel movement. Preferably, the disinfection standard of the first environment is higher than that of the second environment.
[0073] Preferably, the disinfection system 100 determines the first environment by acquiring the movement trajectory of the intelligent detection terminal, thereby determining the areas that need to be disinfected.
[0074] Healthcare workers' movement patterns may change due to changes in their job duties. For example, when a hospital admits a large number of respiratory patients, medical staff from wards not belonging to the respiratory department may be seconded to the respiratory department to participate in the treatment of patients. At this time, the movement patterns of the healthcare workers will change compared to before the job change, resulting in a change in the area corresponding to their primary environment.
[0075] Preferably, the disinfection system 100 obtains the movement trajectory of medical personnel by acquiring the movement trajectory of the intelligent detection terminal. When the movement trajectory of medical personnel changes, the disinfection system 100 can re-determine the areas requiring focused disinfection based on the changed movement trajectory. Preferably, the management platform 110 can record and learn the movement trajectory and hotspot locations of the intelligent detection terminal to form multiple hotspot locations or hotspot trajectories. Preferably, after determining the areas requiring focused disinfection based on the acquired movement trajectory of the intelligent detection terminal, the management platform 110 can generate a tracking disinfection plan based on the key disinfection areas, enabling the air disinfection device 120 to disinfect the key disinfection areas. Preferably, when generating the tracking disinfection plan, the management platform 110 can set disinfection priorities based on the number of overlapping movement trajectories of medical personnel or the duration of their stay. Preferably, the management platform 110 can collect the movement trajectories of the smart detection terminals worn by each medical staff member to obtain their movement trajectories. When two or more medical staff members' movement trajectories overlap, the disinfection priority of the real area corresponding to the overlapping part of the trajectory increases, allowing the air disinfection device 120 to prioritize or frequently disinfect that area when implementing the disinfection plan. When medical staff members' movement trajectories overlap, the flow of medical staff in the real area corresponding to the overlapping part of the trajectory increases. If the disinfection of that area is not up to standard, the probability of viruses and bacteria spreading in that area increases. Preferably, the disinfection priority of the real area corresponding to the overlapping part of the trajectory increases with the increase of the number of overlapping trajectories.
[0076] Preferably, based on the characteristics of the intelligent detection terminal entering and exiting the disinfection hotspot location frequently and staying for a long time, the disinfection system 100 uses the intelligent detection terminal to measure the disinfectant concentration level in the disinfection hotspot location in the near field. This enhances the detection frequency of disinfectant concentration at the disinfection hotspot location without setting up additional detection equipment, and enables timely acquisition of changes in disinfectant concentration at the disinfection hotspot location, so as to adjust the disinfectant concentration level at the disinfection hotspot location in a timely manner.
