Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Example one
The embodiment of the application provides a method for confirming indoor close contacts of an infectious disease patient, and the method can be applied to a public security node server. As shown in fig. 1, the method specifically includes the following steps.
Step 101, acquiring a first broadcast message sent by a community node from a block chain network.
Wherein the first broadcast message includes a set of first image information including first image information of a first contact having contact with an infectious disease patient.
The set of first image information includes a plurality of first image information, each of which corresponds to image information of a contactee who has contacted the infectious disease patient. For example, if Zhangzhi contacts with the patient with infectious disease, the image information of Zhangzhi is acquired; if the Wangzhi also contacts with the infectious disease patient, the image information of the Wangzhi can be acquired, and the like, so that the image information of all the people in the community which have contact with the infectious disease patient can be checked and acquired through the community node. To facilitate subsequent isolation or confirmation of such contacts.
In some implementations, the first image information is obtained by the community node acquiring images of the patient with the infectious disease and the first contact person by using an image acquisition device.
For example, the community node searches data related to the infectious disease patient through a video monitoring system, analyzes the data, determines that the infectious disease patient appears near a B-building in the A-community from 2 months 10 to 2 months 12, extracts image information related to the infectious disease patient during the period, can obtain images or picture information of people who have contact with the infectious disease patient, generates first image information, and forms a set of the first image information by the first image information.
Wherein the second broadcast message includes user information of a second contact in the second set of contacts, the user information including an identification of a terminal used by the second contact and identity information of the second contact.
Specifically, the identifier of the terminal may be a mobile phone number used by the second contacter, or a physical address corresponding to a device, such as a tablet computer capable of performing mobile network communication, used by the second contacter, and the like, where the identifier of the terminal is only an example, and in the specific implementation, the identifier of the terminal may be specifically set according to a specific situation, and identifiers of other terminals that are not described are also within the protection range of the present application, and are not described herein again.
And 103, searching a public security system database according to the identity information of the second contact person to obtain second image information of the second contact person.
For example, through the identity card number of the second contact person, the database of the public security system is searched, the identity card photo collected by the second contact person when the second contact person transacts the identity card can be obtained, or the picture information of the second contact person collected by the second contact person when the second contact person transacts the identity card such as a passport and the like can be searched, so that the second image information of the second contact person can be determined through the picture information. The above-mentioned manner for acquiring the second image information is only an example, and in the specific implementation, the specific setting may be specifically performed according to specific situations, and other manners for acquiring the second image information that are not described are also within the scope of the present application, and are not described herein again.
And step 104, determining that the second contact person is an indoor close contact person of the infectious disease patient according to the second image information and the first image information.
It should be noted that, if the patient with infectious disease enters the room, the positioning information corresponding to the user in contact with the patient with infectious disease cannot be very accurate, and sometimes coincides with the position information of the patient with infectious disease; and if the terminal used by a contact person who has contact with the infectious disease patient is in a power-off state, the information of the contact person cannot be acquired. The specific situation of the contact person who has contact with the infectious disease patient can be more accurately locked through the first image information acquired by the community node and the second image information sent by the operator node, so that the second contact person is further checked out to be an indoor close contact person of the infectious disease patient, the omission of the indoor close contact person is avoided, the treatment efficiency of a medical institution is improved, the infectious disease patient can be treated with a definite diagnosis as soon as possible, and the public safety is improved.
In some implementations, determining, from the second image information and the first image information, that the second contacter is an indoor close contacter of an infectious disease patient includes: searching the first image information according to the second image information; and if the first image information is determined to contain the second image information, determining that the second contact person is an indoor close contact person of the infectious disease patient.
For example, the first image information and the second image information are compared to obtain a comparison result, which may be the same or different. When the first image information and the second image information are the same, then it may be determined that the second contacter is an indoor intimate contacter of an infectious disease patient.
And 105, generating and sending a third broadcast message to the blockchain network according to the identity information of the second contact person and the identifier of the terminal used by the second contact person.
Specifically, when the epidemic situation monitoring node acquires the third broadcast message from the blockchain network, the identity information of the second contact person and the identifier of the terminal used by the second contact person can be obtained through analysis of the third broadcast message. And then, searching the second contact person according to the identifier of the terminal used by the second contact person so as to carry out isolated observation on the second contact person.
In the embodiment, the first image information sent by the community node is obtained from the blockchain network, and meanwhile, the user information of the second contact sent by the operator node is obtained; the public security system database can be searched according to the identity information of the second contact person to obtain the second image information of the second contact person, the second contact person is determined to be an indoor close contact person of the infectious disease patient according to the second image information and the first image information, the related information of the indoor close contact person of the infectious disease patient can be obtained more accurately, the identity information of the second contact person and the identification of the terminal used by the second contact person are sent to the block chain network, the epidemic situation monitoring node can conduct preferential observation on the second contact person, measures such as isolation are taken, omission of suspected infectious disease patients is avoided, the workload of a medical institution is reduced, the efficiency of the medical institution is improved, the patients can be diagnosed and treated as soon as possible, and the safety sense of the public is improved.
Example two
The embodiment of the application provides a method for confirming a contacter of an infectious disease patient, and the method can be applied to an operator node server. As shown in fig. 2, the method specifically includes the following steps.
The infectious disease patient information includes an identifier of a terminal used by the infectious disease patient and a diagnosis time of the infectious disease patient.
Specifically, after an infectious disease patient is diagnosed, the epidemic situation monitoring node needs to track and observe the close contact person of the infectious disease patient to obtain information of the infectious disease patient. Wherein the infectious disease patient information includes: identification information of the infectious disease patient (e.g., identification number, name of the infectious disease patient, etc.), picture information of the infectious disease patient, identification of a terminal used by the infectious disease patient (e.g., cell phone number), and diagnosis time of the infectious disease patient.
It should be noted that each operator has its own operation number segment, and if some mobile phone number of the terminal is in the operation number segment to which the operator a belongs, it indicates that the terminal is provided with the mobile network service by the operator a, so that it can be determined that the operator corresponding to the terminal used by the infectious disease patient is the operator a.
And step 203, screening and obtaining a first terminal set within a preset distance range according to the category of the operator, the identifier of the terminal used by the infectious disease patient and the diagnosis time of the infectious disease patient.
Wherein the first set of terminals includes the first terminal. The category of the operator may also be distinguished by the name of the operator, so that the node to which the operator belongs (e.g., the node server of the operator a, etc.) can be specifically determined.
In some implementations, step 203 can be implemented as follows: if the type of the operator is determined to be the same as the type of the operator corresponding to the node, determining a travel track diagram of the infectious disease patient according to the identifier of the terminal used by the infectious disease patient; and determining a first terminal set according to the travel track graph and the diagnosis time of the infectious disease patient.
Wherein, the journey trajectory diagram includes: the elapsed time information of the infectious disease patient and the position information of the infectious disease patient corresponding to the time information. For example, the location information may be longitude and latitude information of an infectious disease patient, or geographical location information of an infectious disease patient appearing near a building within a certain time period. The above location information is only an example, and may be specifically set according to specific situations, and other location information not described is also within the protection scope of the present application, and is not described herein again.
In some implementations, determining the first set of terminals from the travel trace map and the time of the infectious disease patient's diagnosis includes: determining the base station identification passed by the infectious disease patient in a preset time period according to the travel track graph; and screening the first terminals within a preset distance range according to the base station identification and the diagnosis time of the infectious disease patient, and forming a first terminal set by the first terminals.
For example, the operator node a labels the base station information on the travel trace graph one by one to obtain a base station set, and according to the base stations in the base station set, may determine within a certain time range of the confirmed diagnosis time (for example, if the confirmed diagnosis time is 2 months, 5 days, 14 days, then within a time period of 2 months, 3 days to 2 months, 7 days, the terminal used by the infectious disease patient is specifically registered in the coverage of which base station), and register the mobile phone user information to the base station. Then, a set of mobile phone numbers within a preset distance range (e.g., 5 meters, 10 meters, etc.) is obtained through screening, and the distance between the mobile phone number in the set of mobile phone numbers and the mobile phone number used by the infectious disease patient is within the preset distance range.
And step 204, determining the identity information of the second contact person according to the identifier of the first terminal.
Specifically, if the identifier of the first terminal (for example, the mobile phone number corresponding to the first terminal) is in the mobile phone number set, it is determined that the user of the first terminal is the second contact person of the patient with the infectious disease, and meanwhile, the database of the operator is searched through the identifier of the first terminal, so as to obtain the identity information (for example, the identity card information used when the second contact person opens an account) of the second contact person corresponding to the first terminal, and the second contact person constitutes the second contact person set.
Specifically, after acquiring the identity information of the second contact person, the public security node searches a public security system database according to the identity information of the second contact person to acquire second image information of the second contact person; then, according to the second image information and the first image information sent by the community node, the second contact person is determined to be an indoor close contact person of the infectious disease patient.
In the embodiment, a first terminal set within a preset distance range is obtained by screening through an operator node server according to the category of an operator, the identifier of a terminal used by an infectious disease patient and the diagnosis time of the infectious disease patient; and the identity information of the second contact person is determined according to the identification of the first terminal, so that the second contact person who has contact with the infectious disease patient can be quickly screened out, the screening speed of the suspected infectious disease patient is increased, the omission of the suspected infectious disease patient is avoided, the infectious disease patient can be diagnosed and treated as soon as possible, the efficiency of a medical institution is improved, and the public safety sense is improved.
