With the continuous world abuse of new coronary pneumonia, more and more people pay attention to virus isolation and environmental sanitation, and cleaning products such as sterilizing hand sanitizer and the like are frequently used besides a mask which is carried by a person when the person goes out, so that virus infection is avoided as far as possible. For enterprises, virus prevention is more important, and once a workplace is infected by people, the workers often need to shut down to carry out overall disinfection and cleaning, even a large number of employees need to be isolated at home, so that the whole company stops, and enterprise operation is seriously influenced.

However, most of the current indoor virus protection belongs to passive epidemic prevention, for example, a body temperature sensor is arranged at an entrance, once the temperature of a human body rises, people are refused to enter the room by starting an alarm; or whether people who enter or exit the room wear the mask or not is checked through manpower, and the people cannot enter the room; or whether the observer has obvious diseases or not to decide whether to enter the room.

The passive epidemic prevention has the following defects: if the human body is infected with the virus and does not have obvious symptoms such as temperature rise, cough and the like, the method is difficult to exert the effect, so that the infected person can still cause the problems of cluster infection and the like by means of droplets, contact and the like after entering the room. Therefore, the inventor believes that an active protection system should be provided to sterilize and disinfect the room when people move in the room or immediately after the people move, so that the probability of virus spreading in the room can be greatly reduced.

Detailed Description

The invention mainly takes passive epidemic prevention as active epidemic prevention, and uses a biological footprint detection unit to collect the footprint of space organisms so as to master the space infection risk. An analysis and statistics unit is used for carrying out statistics and data analysis on all detection results of the biological footprint detection unit and analyzing whether a control unit is needed to start a sterilization unit to sterilize the space. Therefore, the survival probability of the virus and bacteria in the space can be greatly reduced, the infection way is avoided, and then, the specific sterilization mode of the creation is introduced below.

The following description is directed to the biological footprint detection unit;

the biological footprint detection unit can be placed in the space and used for detecting the activity condition of organisms in the space to obtain a biological footprint detection result, the biological footprint detection unit comprises a microorganism detection unit, and the microorganism detection unit collects the condition of microorganisms in the space by using a space collection method to serve as the biological footprint detection result. The biological footprint detection unit can also comprise a carbon dioxide concentration detection unit, wherein the carbon dioxide concentration detection unit is used for collecting the concentration of carbon dioxide in the closed space to be used as a biological footprint detection result, and can be used for judging the number of indoor organisms according to the concentration of the carbon dioxide, and the concentration of the carbon dioxide also means the infection risk. In addition, the biological footprint detection unit also comprises a camera detection unit, the biological footprint detection unit is used as the biological footprint detection result according to the shooting result of the camera detection unit, the biological footprint detection unit can also be a heat source image detection unit, the heat radiation remained by the organism is used as a detection source, so that the biological movement track is obtained and used as the biological footprint detection result, and in addition, the biological footprint detection unit can also utilize the camera detection unit and the heat source image detection unit to be matched with each other, so that the more accurate biological movement track, including a biological activity track, a biological movement track, a biological contact track and the like, can be obtained. In the case of living things, hands are one of the important routes for infection, virus and bacteria dissemination, and it is avoided that when the hands of a patient are touched by an object in the space, other people touch the same object to cause virus infection. Judging the contact condition of the symptomatic patient and the object in the space to obtain the biological contact track according to the thermal image residual image result of the heat source image detection unit; the control unit can control the ultraviolet germicidal lamp to track and disinfect along the biological contact track, so that any way that viruses can be infected is avoided.

In addition, because the biological droplet has a wider range of infection and more randomness, the droplet trajectory including the biological is preferably detected when the biological footprint is detected, and the detection method of the present creation mainly analyzes the possible flight trajectory and path of the droplet by detecting the movement of the mouth of the biological, so as to obtain a droplet trajectory, and the implementation method thereof is as follows: the biological footprint detection unit can be used for analyzing the oral motion of the organisms in the space according to the heat source distribution result of the heat source image detection unit and analyzing the droplet track according to the oral motion; the control unit can control the ultraviolet germicidal lamp to track and disinfect along the spray track according to the spray track.

As droplet infection and contact infection belong to one of virus and bacterium infection routes, the ultraviolet sterilization can be effectively carried out on various virus and bacterium infection routes in the mode, so as to ensure that germs in the space are difficult to survive and greatly reduce the possibility of germ infection. In addition, in the above sterilization mode, the control unit may perform sterilization and disinfection in real time according to the biological footprint detection result when biological activity is present in the space, and since ultraviolet rays are harmful to biological skin and project onto the biological skin when ultraviolet rays are performed in real time for avoiding sterilization, an indication projection lamp is preferably further provided in the space, the control unit may control the indication projection lamp and the ultraviolet sterilization lamp to project along the biological movement track at the same time, and light rays emitted by the indication projection lamp serve as an indication to prompt personnel to avoid the ultraviolet rays.

The biological footprint detection unit further comprises a microphone unit for detecting sounds emitted by the living being in the enclosed space, wherein the sounds include language, cough, sneeze, crying, laughing and the like, and particularly the cough sounds emitted by the symptoms specific to the new coronary pneumonia are identified. When the indoor space detects that the same person coughs continuously or the coughs of a plurality of persons, the analysis and statistics unit judges the next action. Furthermore, the microphone sound receiving unit collects the sound emitted by the same organism in the closed space, recognizes that the cough, sneeze, crying and the like emitted by the same organism exceed a certain upper limit, and informs the background of increasing the alertness. Regardless of the implementation of the biological footprint detection unit, it is the biological footprint detection unit referred to in this specification for detecting the biological activity footprint in the space.

The following description is directed to the water quality detection unit;

the water quality detection unit and the water sterilizer can be placed in a water supply unit, such as a water tower of a building and a drinking water environment, for detecting the water quality condition to obtain a water quality detection result. The water quality detection unit mainly has the function of detecting the water quality condition in real time, whether the water quality condition is polluted, infected, poisoned and other high-risk conditions. The water quality detection unit transmits the detected water quality detection result to the analysis and statistics unit at any time. If the analysis and statistics unit judges that the water sterilizer needs to be sterilized according to the water quality detection result, the control unit starts the water sterilizer.

The following is described for the analytical statistics unit;

the analysis and statistics unit can be placed at any position, such as the space, a cloud server and the like, and the analysis and statistics unit has two main functions: the first is to connect the biological footprint detection unit, receive the detection result from the biological footprint detection unit, and record the statistics. And simultaneously, synchronously analyzing whether the received detection result reaches a set threshold value. If the threshold value is not reached, continuing to receive the message; if the set threshold value is reached, analyzing which unit signal value exceeds the threshold value, and starting the corresponding sterilization device. For example: the microorganism detection unit, the carbon dioxide concentration detection unit, the microphone sound receiving unit and the like start a circulating sterilizer; and if the ultraviolet sterilization lamp is the camera detection unit or the heat source image detection unit, starting the ultraviolet sterilization lamp. The water quality detection unit starts a water sterilizer. Regardless of the implementation of the analysis and statistics unit, all that can be linked to the biometric footprint detection unit and the control unit are the analysis and statistics unit referred to in this specification.

The following is explained for the control unit;

the control unit is in information connection with the ultraviolet germicidal lamp, the circulating sterilizer and the water sterilizer, and the control unit can be arranged in the space and can also be arranged in a central control room in a remote monitoring mode so as to be remotely monitored and sterilized. The ultraviolet germicidal lamps can be placed in a space, for example, the number of the ultraviolet germicidal lamps is preferably a plurality, the ultraviolet germicidal lamps are dispersedly arranged at each position in the space so as to sterilize each position in the space without dead angles, and the ultraviolet germicidal lamps are preferably arranged at the top in the space so as to sterilize in a top-down projection mode. Even the ultraviolet sterilizing lamp can be moved everywhere in the space by installing a rail conveying unit indoors and conveying the ultraviolet sterilizing lamp through the rail, so that the ultraviolet sterilizing lamp has no dead angle.

The sterilization mode belongs to a precise projection sterilization mode, and the biological movement track is precisely analyzed mainly through the heat source image detection unit and the camera detection unit, and the ultraviolet sterilization lamp is controlled to sterilize aiming at the biological movement track. For example, when a living being enters the space, the living being footprint detection unit starts to detect, the moving track of the living being is transmitted to the analysis and statistics unit for determination, and then a message is sent to the control unit, and the control unit immediately controls the ultraviolet germicidal lamp to project, track and disinfect along the moving track of the living being according to the moving track of the living being, so as to reduce the probability of virus and bacteria remaining in the space.

In addition, the spread of germs may also be transmitted from one space to another space through the air conditioning system, which causes that the other space has no evidence of biological activity, but may be filled with germs inside, so that the personnel still have the risk of infection after entering, and in order to avoid such a situation, the creation may further be implemented as follows: a microorganism detection unit is arranged in the space and can be used for indirectly evaluating the microorganism quantity in the space to obtain a microorganism quantity detection result; a carbon dioxide concentration detection unit is further arranged in the space and can be used for detecting the carbon dioxide concentration in the space to obtain a carbon dioxide concentration detection result, and the carbon dioxide concentration is positively correlated with the biomass, so that the biomass in the space can be further knocked; the circulating sterilizer is communicated with the space; the control unit is in information connection with the microorganism detection unit, the carbon dioxide concentration detection unit and the circulating sterilizer, and when the analysis and statistics unit judges that the microorganism number detection result exceeds a default value, the control unit starts the circulating sterilizer. Or when the analysis and statistics unit judges that the detection result of the carbon dioxide concentration exceeds a default value, the detection result indicates that the carbon dioxide concentration is increased due to the increase of the number of organisms in the space, so that the infection and the propagation risk are increased, and the control unit also starts the circulating sterilizer.

For example, although there is no evidence of biological activity in the space, when the analyzing and counting unit determines that the number of microorganisms in the space is too high according to the detected number of microorganisms, the control unit will activate the circulating sterilizer to reduce the number of microorganisms in the space, and the circulating sterilizer not only performs the air circulation operation, but also preferably simultaneously purifies (e.g., sterilizes) the air to kill the microorganisms in the space. And when the ultraviolet sterilizing lamp is started, the control unit can also synchronously control the ultraviolet sterilizing lamp to perform ultraviolet sterilization on the space, so that the overall sterilizing effect is improved to the best.

In addition, in the above-mentioned embodiment when the measured microorganism count is higher when there is no sign of biological activity in the space, when there is biological activity in the space, the measured microorganism count is higher again, this creation preferred be in be equipped with a suggestion unit in the space, the suggestion unit can be warning light, bee calling organ, broadcast etc. and it is the suggestion unit that this specification indicated to have the suggestion effect everywhere. And when the analysis and statistics unit judges that the detection result of the number of the microorganisms exceeds a default value, the prompt unit is started, and the control unit 3 starts the ultraviolet germicidal lamp until the analysis and statistics unit judges that no organisms exist indoors according to the biological footprint detection result. Therefore, under the condition that the space has biological activity and the number of the detected microorganisms is high, the organisms in the space are driven away by the prompting unit and then are thoroughly sterilized.

For avoiding ultraviolet germicidal lamp increases along with the live time, causes output power to be as anticipated leading to sterilizing effect not honor, consequently this creation further utilizes the illuminometer as retrospective control, and its implementation is: an illuminometer is further arranged in the space, the illuminometer is in information connection with the control unit, the illuminometer detects the illuminance of ultraviolet rays to obtain an illuminance detection result while the ultraviolet germicidal lamp projects along the biological movement track, and the control unit determines whether to improve the output power of the ultraviolet germicidal lamp according to the illuminance detection result.

For example, when the uv germicidal lamp is started, the illuminometer is simultaneously actuated to detect the illuminance of the uv germicidal lamp, and when the control unit determines that the illuminance is not as expected according to the illuminance detection result, the control unit controls the uv germicidal lamp to increase the output power so that the illuminance detection result meets a default value, and simultaneously, the control unit preferably synchronously transmits the determination result back to the central control room to inform relevant managers that the uv germicidal lamp needs to be noticed or replaced, so as to maintain the overall uv germicidal quality of the present creation.

In addition, ultraviolet germicidal effect is mainly along with projection time, projection power, and even germ kind also can influence germicidal effect, for letting this creation can maintain best germicidal effect, this creation further provides intelligent learning function, and its implementation mode is: the control unit can be used for judging the biological number of the space according to the shooting result of the camera detection unit and the detection result of the heat source image detector; in the process that the ultraviolet germicidal lamp is switched from starting to closing, the control unit can control the microorganism detection unit to actuate to obtain a microorganism variation detection result, and the projection time, the projection power, the biomass and the microorganism variation detection result of the ultraviolet germicidal lamp are made into a sterilization record.

Therefore, the sterilization record can be learned subsequently, for example, the projection time and the projection power can be adjusted and controlled to have the best sterilization effect according to the detection result of the microorganism variation, or the projection time and the projection power can be changed according to the number of the organisms, so that the composition has the best sterilization protection effect.

In order to prevent any possible pathogenic bacteria propagation path in the space as far as possible, the device further judges whether a person in the space wears a mask through the camera detection unit, once the person in the space is judged not to wear the mask, the analysis and statistics unit controls the prompting unit to actuate, so that the person in the space is prompted to immediately wear the mask, and meanwhile, the detection result is preferably synchronously transmitted to the central control room, so that a manager of the central control room is informed to pay attention or go to the central control room for dissatisfaction.

In addition, in view of the rising of global new coronary pneumonia, in order to effectively find out a person who can be diagnosed in advance, the present creation is to further arrange the sound receiving unit in the space, the sound receiving unit mainly collects various sounds in the space to obtain sound detection data, and then transmits the sound detection data to the analysis and statistics unit. Then, the analyzing and counting unit will start to analyze the sound detection data, if the analysis result shows the sound of the possible symptoms of the patient with new coronary pneumonia symptoms such as cough, acute respiration, or sneeze, and the analyzing and counting unit will judge that the mouth of the living body has motion according to the photographing result, which indicates that the person in the space has a certain probability of suffering from coronary pneumonia, bronchial related diseases or other diseases with similar symptoms, at this time, the analyzing and counting unit will send out a notification signal, which can be sent to a central control center or a government epidemic prevention center.

In summary, the present application is consistent with the principles defined by the patent laws, and the following descriptions are only illustrative of the preferred embodiments of the present invention, and the claims of the present application are mainly listed in the claims.
