Description

Intelligent system for efficiently preventing epidemic propagation by using mobile phone and network

Technical Field

The invention relates to the technology of preventing infectious diseases, in particular to an intelligent system for efficiently preventing epidemic propagation by using a mobile phone and a network.

Background

During an epidemic, identifying suspected persons and preventing the spread of the epidemic are urgent works. The temperature of the road man and the driver can be checked at the intersection. If not carefully checked, the epidemic is easily spread. If the body temperature is measured carefully one by one, cross infection is easy to occur, road congestion is caused, and even the development of local economy is influenced.

The inspector often asks the passer for three questions: 1. from where; 2. the recent body has fever or not; 3. there is no experience of contacting the infectious disease patient. In the face of inquiries, some passers-by are confused about a false word for some personal reasons. And some people cannot answer clearly in a short time.

And taking isolation measures for suspected persons. Body temperature is measured periodically and the whereabouts are reported. Obviously, the suspected person reports the body temperature and the track, the error is large, and even false components exist.

The epidemic prevention has no scientific and technological content, the efficiency is extremely low, epidemic prevention personnel are tired, and the prevention is not better.

The application of mobile phones and networks and intelligent acquisition and identification can be used for preventing epidemic propagation. The intelligent informatization of epidemic prevention work is a great trend. Conservative prediction: the application of mobile phone and network, and AI can raise epidemic prevention efficiency by above five times. Completely changes the passive situation of epidemic prevention.

Firstly, the body temperature data, the track data and the contact history data of a user are collected and identified by using a mobile phone and a network through AI. And AI is used for analyzing data and rapidly identifying suspected persons. Importantly, the method comprises the following steps: the innovative science and technology is used for ensuring that the measurement is carried out in advance at home and the fake can not be made. Ensure the accuracy and reliability of the data.

Secondly, the work efficiency of the passerby inspection is greatly improved. The flashing pass code is displayed in the mobile phone APP, and the inspector looks over the pass code and confirms that the health of the mobile phone APP reaches the standard at a distance of 3 meters. Therefore, the body temperature does not need to be measured at the intersection, and the convenience is brought to people for going out to the greatest extent. And limits the trip of suspected persons by network technology.

Disclosure of Invention

The invention aims to: the invention relates to an intelligent system for efficiently preventing epidemic propagation by using a mobile phone and a network; identifying suspected persons by using AI and limiting the suspected persons to go out; the efficiency of the passerby inspection is doubled, and the technical feasibility is high; is suitable for epidemic situations of various infectious diseases, and realizes the prevention of the spread of the epidemic situations by high technology.

The system of the invention comprises: the system comprises a smart phone, a service platform, a display device, a management terminal and an inspection terminal.

The smart phone is a communication terminal carried by a user, and an epidemic prevention APP needs to be installed in the smart phone. A particular smartphone may be available in a variety of models. The smartphone is called a mobile phone for short.

The user needs to install the epidemic prevention APP for the first use, and registers the relevant information. For example: name, identification card number, occupation, residence address, contact, co-resident, taking user pictures, etc.

The epidemic prevention APP is special software for mobile phone epidemic prevention; starting an epidemic prevention APP regularly every day, prompting a user to measure human body indexes and recording measured results; acquiring a track position and a time period of a user through mobile phone positioning software; and the AI software is used for exchanging and analyzing with the user to form an epidemic prevention index of the user, and the epidemic prevention index is uploaded to a service platform.

The AI software refers to software for man-machine communication, intelligent identification and automatic learning with users; the method comprises the steps of providing questions to a user, identifying answers of the user, and adopting corresponding communication processes according to each answer; if the user has questions, after correct answers are given, the associated questions of the questions asked by the user are intelligently identified, and targeted questions are asked; the process of learning and optimizing man-machine communication is automatically accumulated, and data and information required in epidemic prevention indexes of the user are obtained.

The epidemic prevention indexes comprise: human body indicators, whereabouts data, contact history data of the user over several recent dates. The dates are mainly related to epidemic situations, for example: the day was set to 12 days.

The human body index refers to the name, times, time, data and information of specific data of a human body.

The specific data of the human body mainly refers to the body temperature of a human body, and also refers to other indexes or information which can be detected at home and have close relation with infectious disease symptoms, and secondary symptoms. For example: measuring certain index in blood at home, and testing results by using test paper. Secondary symptoms are: characteristics of cough, characteristics of pain, characteristics of appetite, characteristics of fatigue, characteristics of urine, and the like.

In the emergency time of epidemic situation, the common thermometer can be adopted to measure the human body index, and the body temperature of the user can be measured. The more preferable scheme is as follows: the measuring device connected to the mobile phone is described later.

The track data mainly refers to the residence address and time period of the user and the names of co-resident persons; the user goes out to the geographic position and the time period of the crowded place and contacts with the names of the people in short distance; the track and time period of the user in the epidemic situation area and the name of the accompanying person are obtained; the line name, time period and accompanying person name of the user riding the vehicle. The epidemic situation area refers to the origin of the epidemic situation or the high-emergence area of the epidemic situation.

The contact history data refers to the geographic position and time period of the user contacting the patient, the name of the patient and the relationship between the user and the patient. Contact history refers to the experience of a user contacting a patient.

The epidemic prevention APP determines the time for starting the epidemic prevention APP at regular time and determines the functions and parameters related to the epidemic prevention indexes according to the characteristics of different infectious diseases, the grade of epidemic situations and the characteristics of users.

According to the data in the epidemic prevention indexes, when the human body indexes of the user exceed the standards, the epidemic prevention APP determines the user as a suspected person; when the human body index of the user is qualified, the AI software exchanges and analyzes to identify that the user has the track in the epidemic situation area or has the contact history, and the user is determined as the suspected person.

The suspected person refers to a person who is suspected to have an infectious disease.

Dividing suspected persons into a plurality of grades by the epidemic prevention APP according to data in the epidemic prevention indexes, and suggesting different isolation measures; and for the serious suspected personnel, the user is advised to go to the hospital for examination and treatment in time.

The epidemic prevention APP uses positioning software in a mobile phone to identify the suspected person to give out sound and image-text warning when going out illegally; when suspected people are identified to enter a dense place in violation, high-level sound and image-text warning are sent out; and recording the track data and time of the suspected person on the illegal trip. Therefore, the traveling of suspected personnel is limited by network technology.

In addition, the user can consult, learn and report epidemic situations to the service platform through the epidemic prevention APP.

For children and the old who do not have mobile phones. An epidemic prevention APP can be additionally installed in the mobile phone of the family and the family. And to register, the epidemic prevention APP reminds that the body temperature needs to be measured regularly, and people without mobile phones can report the whereabouts and contact history. Obviously, in the floating population, only a very few people do not have mobile phones.

The service platform refers to a large computer server and peripheral hardware; installing working software, AI comparison software and epidemic situation analysis software of the service platform in the service platform to assist workers; the system also comprises a user registration database, a patient track database, a suspected personnel database, consultation and communication software, map software and epidemic prevention APP downloaded by the mobile phone of the user.

The user registration database is mainly used for storing information of each user during registration and also storing epidemic prevention indexes updated by the user each time the user uses the epidemic prevention APP.

The patient database mainly stores the information of the patient during registration, also stores epidemic prevention indexes updated by the patient using the epidemic prevention APP every time, and records the name of the receiving and treating hospital.

The patient track database is used for recording the track data of each patient within a plurality of time periods, and the track data is time-efficient. The specific time efficiency is set by the staff according to epidemic situations.

The suspected person database is mainly used for storing information of suspected persons during registration, and also used for storing epidemic prevention indexes updated by the suspected persons each time the suspected persons use the epidemic prevention APP, and the grades of the suspected persons and the records of illegal trips of the suspected persons.

And the service platform receives the epidemic prevention indexes of the mobile phone of the user, compares the trace data of the user with the data in the patient trace database by using AI comparison software, and analyzes and identifies the contact history of the user.

AI alignment software was applied for three cases: 1. the user does not have the contact history, the user is confirmed to be a health qualified person, and the user is granted a pass code. 2. The user has doubtful points in the contact history, does not grant a pass code and needs to perform recheck; and the service platform informs the epidemic prevention APP to communicate with the user by using AI software and recheck suspicious points. 3. And (4) confirming that the user has the contact history, not granting the pass code, and confirming the user as a suspected person.

The pass code is proof that the user belongs to a health qualified person and is also a pass for the user to go out.

The health up-to-standard personnel refer to that epidemic prevention indexes of users are qualified, and the method comprises the following steps: the human body index of the user is qualified, and the user has no trace data and contact history data in epidemic situation areas.

The pass code is a dynamic mark consisting of a graphic code, a flashing icon and a user head photo, and can be displayed prominently in the user mobile phone epidemic prevention APP.

The graphic code mainly refers to a bar code, a two-dimensional code or a multi-dimensional code. The information in the graphic code mainly comprises: valid time of the pass code, user name, identification card number, age, gender, contact information and link address of the user photo.

The flashing icon is designed beside the graphic code, and the shape, color, content and flashing mode of the flashing icon can be changed frequently.

The flashing icon is designed to be strictly copy and counterfeit proof and convenient for the inspector to view and identify.

The head portrait refers to a photograph in which the face occupies a large area of the screen. The epidemic prevention APP can display the photos in an enlarged mode to form head photos according to the photos of the user. The long-distance observation of the detection personnel is facilitated.

The valid time of the pass code is from the moment when the user updates the epidemic prevention index for the last time to the end of the specified time. When the pass code exceeds the effective time, the pass code cannot be displayed in the epidemic prevention APP, and a user is reminded to use the epidemic prevention APP to measure the human body index in time. For example: the designated time was set to 6 hours.

When the user is confirmed as a patient by a doctor, the user can set the user as the confirmed patient in the epidemic prevention APP, or a worker inputs the name and the identification number of a new patient through the management terminal. And the service platform automatically adds the trace data in the epidemic prevention indexes of the new patient into a patient trace database.

After the service platform has a list of new patients, a plurality of users having a contact history with the new patients are automatically identified as suspected persons. And the service platform sends a confirmation notice to the mobile phone epidemic prevention APP of the suspected person.

The service platform sends different notices, epidemic prevention knowledge, matched measures and rules and requirements for propaganda and epidemic prevention to patients, suspected personnel of different levels and health qualified personnel through the epidemic prevention APP. Therefore, the mobile phone and the network can be used for respectively managing patients, suspected personnel and health standard-reaching personnel.

The service platform is connected with the smart phone and the inspection terminal in a telecommunication network mode.

The service platform is connected with the display devices and the management terminals in a wired or wireless mode.

The display device is a large-scale computer screen installed in an epidemic prevention management center and can display related epidemic situation data and city epidemic situation distribution diagrams. The common watching of field personnel is facilitated.

The management terminal refers to a plurality of desktop computers installed in an epidemic prevention management center; the working personnel can manage and control the work of the service platform through the management terminal; the staff operates the management terminal and gives corresponding management measures according to the grade of suspected staff; epidemic situation analysis can be carried out according to the grasped epidemic prevention indexes of the users, and different notifications and management are given to different users; the functions and parameters of the epidemic prevention APP can be set through the service platform, and the epidemic prevention APP software is upgraded.

The staff sets up through the management terminal, lets the service platform automatically accept user's consultation, report epidemic situation, gives the direction of user's scientific epidemic prevention.

The check terminal is a communication terminal capable of scanning the pass code to obtain the information in the pass code; and may retrieve and display the user's photo from the user's photo link address. The inspector uses the inspection terminal to verify that the information of the user is correct and then grants permission.

The specific inspection terminal can adopt a smart phone or a commercially available device specially used for scanning inspection. In the inspection terminal, the working software needs to be installed.

The system has two ways to check passers-by. One is that the inspector uses the inspection terminal and scans the pass code in the mobile phone of the passer. Still another is that the inspector visually checks the passcode.

The inspection terminal is used for scanning passcodes of passers-by, and is a stricter inspection mode. Is particularly suitable for the entrance of important places such as airports and the like.

The step of checking the pass code by eyes means that an inspector can be 3 meters away from a passerby and can check the head photos and the flashing icons in the passerby mobile phone and the pass code by eyes, so that the passerby is proved to be a healthy qualified person and is granted permission. Therefore, the body temperature measurement at the intersection can be cancelled, and the efficiency of inspecting passers-by is thoroughly improved. Is particularly suitable for the inspection of intersections and shopping malls.

If no passcode exists in the mobile phone of the passer, the inspectors need to ask questions in detail and need to measure the body temperature of the passer on site. Even forbidding trip, implement isolation.

Further, the system is additionally provided with a measuring device.

The measuring device is a device for measuring the human body index of a user, and the measuring device is connected with the smart phone in a wired or wireless mode. The measuring device can detect one human body index and can also detect a plurality of human body indexes in a multifunctional way.

The mobile phone epidemic prevention APP is matched with the measuring device, and measured data are automatically stored in epidemic prevention indexes of users. And the false components can be reduced because no manual counting is involved in the measurement process.

There are various ways to measure body temperature. For example: skin contact, oral, infrared measurements, etc.

The epidemic prevention APP and the measuring device work cooperatively, and technical measures for preventing a user from measuring and making a fake and verifying the real identity of the user are provided. The method specifically comprises the following steps: audio verification, or image verification.

The audio verification method is that the measuring device has two probes, one for measuring human body index and one for measuring vibration sound. When the user is measuring, the epidemic prevention APP prompts the user to speak; the voice of the user is detected by the contact of the skin of the human body and the vibration sound probe, and the voice is also detected by the mobile phone receiver. If the two detected voices are kept synchronous, it is indicated that one person is measuring and no other person is replacing.

Moreover, the speech characteristics and fixed words of the user speech can be recognized by the epidemic prevention APP. And thus the user cannot let others replace the measurement. The measurement cannot be made false.

The vibration sound probe is a sound pickup probe that vibrates by a solid body, not by air. The vibration sound detecting probe is tightly attached to the skin of the head of a user and picks up the speech of the user.

The image verification method is characterized in that when a user uses a measuring device to measure the body index of the user, the mobile phone epidemic prevention APP simultaneously takes a face picture of the user during measurement. And the service platform application identifies software and can identify photos. Therefore, the identity of the user is verified, and the fake measurement is avoided.

The invention has the main advantages that: before the user leaves a door, the body temperature can be measured in advance, and the epidemic prevention indexes of the user can be obtained through man-machine communication of the epidemic prevention APP. And (3) analyzing the epidemic prevention indexes and identifying suspected persons by using AI software for the epidemic prevention APP. AI comparison software is used by the service platform, suspected personnel are further identified, and health up-to-standard personnel are awarded: and (4) a pass code. The inspector checks the head portrait picture and the flashing icon in the pass code by eyesight, and proves that the user is a healthy qualified person and is granted permission. Therefore, the body temperature measurement of the intersection can be cancelled, and the inspection efficiency of the intersection is thoroughly improved. And strict technical measures are adopted to prevent measurement from being counterfeited and prevent the counterfeit pass code, so that the data is ensured to be accurate and reliable. In addition, the trip of suspected personnel is limited by network science and technology, and the track and time of illegal trips are recorded. The service platform has epidemic prevention indexes of a large number of users, and the geographic positions of patients and suspected persons are mastered. Therefore, the epidemic situation can be analyzed by big data, and related personnel can be managed in batches. The system has advanced technology and feasible technical scheme, and realizes the high-efficiency prevention of epidemic propagation by using the mobile phone and the AI. The system is suitable for comprehensive popularization, establishes a system for controlling the epidemic situation of the whole people and leads the intelligent informatization of epidemic prevention work.

Detailed Description

Referring to fig. 1, a service platform (20) provides support for a wide range of users' smart phones (10). Each smartphone (10) needs to be installed with an epidemic prevention APP. Register and take a picture of the face of the user.

The epidemic prevention APP employs positioning software of a smart phone (10) to automatically acquire and record the track position information of a user according to the acquisition frequency. The collection frequency can be determined by the automatic identification of the epidemic prevention APP according to the grade of epidemic situation, the geographic position and the grade of suspected personnel.

The specific collection frequency can also be modified by workers in the epidemic prevention APP.

A plurality of doctors participate in guidance, a plurality of software engineers compile epidemic prevention APP, and the process of communication and identification with users is carried out according to epidemic situation characteristics to design epidemic prevention APP software. Thus, AI analysis and identification are used to form the human body index, the track data and the contact history data of the user.

And the epidemic prevention APP rapidly identifies by using AI according to the content in the epidemic prevention indexes of the users, and confirms the level of suspected personnel. Examples are as follows:

A. if the human body index of the user seriously exceeds the standard, the exceeding time is long, and the contact history data or the trace data of the epidemic situation area exists, the user is confirmed as the level 1 suspected person. The hospital is informed to accept and check, and mandatory isolation measures are recommended.

B. And if the human body index of the user slightly exceeds the standard and contact history data or trace data of an epidemic situation area exists, confirming the user as 2-level suspected personnel. The hospital is informed to accept and check, and mandatory isolation measures are recommended.

C. And if the human body index of the user seriously exceeds the standard, but no contact history data and no track record of an epidemic situation area exist, the user is confirmed as a 3-level suspected person. The hospital is informed to accept, treat and check, and a centralized isolation measure is suggested to be taken.

D. If the human body index of the user is normal, but the contact history data or the trace record of the epidemic situation area exists, the user is confirmed as a suspected person of level 4, and a separate isolation measure at home is recommended.

Obviously, the work of specifically identifying and confirming suspected persons of the epidemic prevention APP can be set in the epidemic prevention APP by the workers according to the characteristics of the infectious diseases and the epidemic situation.

In addition, the specific names of epidemic prevention APP can obviously be various.

The display device (30) is installed in the central hall of epidemic prevention management for people to watch at the same time. In particular, a large-screen television screen or a rear projection television screen can be adopted.

The management terminal (40) is a plurality of desktop computers which are arranged and installed in an office of the epidemic prevention management center and used by a plurality of workers. The service platform (20) is connected with the display device (30) and the management terminal (40) in a wire mode.

The inspection terminal (50) is an inspection device for inspecting passcode of passerby by scanning at the inspection site of intersection by inspection personnel. The number of specific commercially available examination apparatuses is large, and will not be described here.

The checking terminal (50) is required to be provided with working software matched with the system, and the working software can be communicated with the service platform. The result of the on-site scanning measurement is reported to the service platform, and the information reflected in the pass code of the user and the picture of the user can be displayed in the inspection terminal (50).

A measuring device (60) detects the body temperature of the user. The smart phone (10) is connected with the matched measuring device (60) in a wired or wireless mode.

By using the measuring device (60) connected with the smart phone (10), the false factor in the manual reading process can be eliminated because the manual reading is not needed during the measurement.

The vibration sound probe is fixed inside a sealed shell, so that the vibration sound probe is not sensitive to sound in air, but is particularly sensitive to sound generated by vibration of the shell. The measuring device (60) can be attached to the forehead or ear of the user to detect the speech of the user coming from the skin.

The system uses AI to identify four paths for suspected persons. Firstly, the epidemic prevention APP learns that the human body index of a user exceeds the standard; secondly, recognizing the trace record or contact history of the user in the epidemic situation area by the AI for the epidemic prevention APP; thirdly, the service platform (20) has a question about the contact history of the user, informs an epidemic prevention APP, and the user really has the contact history through communication and reexamination between the epidemic prevention APP and the user; and fourthly, the service platform (20) compares the user's whereabouts data with the data in the patient whereabouts database, and the comparison result has contact history.

Therefore, the function of rapidly identifying suspected personnel by using the mobile phone and the AI is realized.

The hardware around the service platform (20) mainly refers to a standby server, a standby power supply, a large data recording device, a network communication device, an input/output device and the like.

The epidemic prevention APP can monitor the geographical position where suspected people live through positioning software of the smart phone (10). When suspected people carry the intelligent mobile phone (10) to go out and enter a position of a person-crowded place, the suspected people are identified by positioning software of the intelligent mobile phone (10), so that the mobile phone gives out sound and image-text warnings.

The epidemic prevention APP controls the smart phone (10) to send out sound warning, and the picture and text warning is provided in the epidemic prevention APP. And warning suspected persons not to go out, and even not to a person-intensive place.

The high-level sound and image-text warning means that the warning sound is louder and more harsh, and the image-text content of the warning is more severe.

The intensive personnel place refers to a place where map software is arranged in the service platform (20) and workers are marked in the map software through the management terminal (40). For example: supermarkets, schools, subway tunnels, and the like.

Referring to fig. 2, there are three measuring devices (60), each measuring device (60) having a plug that can be inserted into a smartphone. And the mobile phone epidemic prevention APP can guide the user and correctly use the measuring device (60) by voice. And the measured data samples can be automatically recorded.

The user is strictly prevented from making a fake measurement. The recognition software in the service platform is applied to recognize the pictures of the face of the user during measurement, and the pictures during measurement for a plurality of times can be mutually verified. Thereby avoiding the false measurement.

On the left side of fig. 2 is an ear thermometer-like measuring device (60) that measures the body temperature of the inner epidermis of the human ear. The upper right part of fig. 2 is an ear-plugging type measuring device (60) which can be plugged into a human ear to measure the body temperature in the human ear. In the lower right part of fig. 2, there is a flat type measuring device (60) which is closely attached to the skin and can measure the body temperature of the forehead of the user. A measuring device (60) for measuring the forehead body temperature can be practically selected.

The high-level measuring device (60) can be internally provided with a microcomputer chip, so that the measurement is accurate and the function is stronger.

See fig. 3, left side view. The upper part of the pass code is provided with a head photograph. The lower part is provided with a two-dimensional code which can be scanned and identified by an inspection terminal (50). The lower part is also provided with a flashing icon which rotates in an elliptical shape. And two red and blue blocks in the oval. Rotating about the direction shown in the figure.

The right-hand side view of fig. 3 is a display of the handset in the landscape orientation. The upper left is provided with a head photo and the upper right is provided with a two-dimensional code. The lower 9 small squares constitute a flashing icon which can be alternately displayed.

Obviously, the flashing icon of fig. 3 may also surround a circle, enclosing a head portrait, two-dimensional code.

Referring to fig. 4, the service platform receives the epidemic prevention index of the user, and uses AI comparison software to identify and compare the user track data with the patient track database. See in particular the schematic flow diagram of fig. 4.

The foregoing is illustrative of the present invention, and it is apparent that many variations are possible on the basis of the basic concept of the present invention, all of which are within the technical scope of the present invention.
