Detailed Description
In order to make the technical solutions of the present disclosure better understood by those skilled in the art, the present disclosure is further described in detail below with reference to the accompanying drawings and examples.
In which the terminology used in the embodiments of the disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in the disclosed embodiments and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
After the epidemic situation is sent, the key to how to control the epidemic situation is to cut off the transmission of pathogens, but generally transmitted diseases have latent periods, the pathogens are often transmitted to the surroundings through undiagnosed carriers under the condition that people are not aware of the pathogens, and the pathogens are spread and transmitted in a wider range during the latent period. Therefore, how to identify a latentian, determine the possible transmission range of the latentian and remind people around the latentian to pay attention to prevention and protection so as to cut off the transmission of the epidemic situation is important for controlling the epidemic situation, but the current personnel flow is large, and when people do not know that people around the latentian exist probably people with the epidemic situation, people are usually unwilling to carry out effective protection, and how to confirm the suspected people with the epidemic situation and determine the possible transmission path of the people so as to remind people to carry out protection, no good method exists at present.
The following describes the technical solutions of the present disclosure and how to solve the above technical problems in specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a flowchart of a method for tracing suspected persons in an epidemic situation according to an embodiment of the present disclosure, as shown in fig. 1, including:
step S101: searching suspected persons of epidemic situation;
step S102: obtaining the trace of the suspected persons in the epidemic situation;
step S103: searching for target people which are possibly contacted with the suspected epidemic people based on the trail of the suspected epidemic people; and the number of the first and second groups,
step S104: and sending a precautionary reminding message to the target personnel.
Because the common transmitted diseases have latent period, the virus is often transmitted to the surroundings through unidentified carriers under the condition that people are not aware of the latent period, so as to threaten people, and the latent people carrying the virus can have some abnormal symptoms, such as fever, cough and the like, for the epidemic situation, whether people go to the epidemic situation area or not can be used as an important judgment basis for judging whether the people are suspected persons or not, therefore, the suspected persons can be found out according to whether the people go to the epidemic situation area or not and whether suspicious symptoms exist, after the suspected persons are found out, on one hand, the suspected persons need to be subjected to tightening detection and can be confirmed as soon as possible, on the other hand, because people do not know that the latent person is the virus carrier and still go out normally, the trace of the suspected persons needs to be mastered so as to send a precaution message to target persons possibly in contact with the suspected persons, the target personnel are reminded to pay attention to protection, the mask is worn, the gloves are worn, more contact with suspicious people with epidemic situations is avoided, and virus propagation is reduced.
Further, the searching for suspected persons of epidemic situation includes:
inquiring a mobile phone number which establishes communication connection with a base station in an epidemic situation area within a first preset time period;
calculating the total time length T of the communication connection between the mobile phone number and the base station in the epidemic situation area;
judging whether the total time length T is greater than or equal to a first preset time length T or not1；
If T is greater than or equal to T1Tracking the geographical position of the user of the mobile phone number in real time to acquire the current body temperature value of the user;
judging whether the current body temperature value of the user of the mobile phone number is greater than a preset temperature value or not;
and if the temperature is higher than the preset temperature value, marking the user of the mobile phone number as a suspected epidemic situation person.
The suspected epidemic people are judged by mainly confirming whether people go to an epidemic area or not and whether suspicious symptoms exist, and because people carry the mobile phone when the people appear at present, the whereabouts of people can be confirmed through the position of the mobile phone. Wherein the first preset time period refers to the time period of the longest latency of the past epidemic; after confirming suspected persons of epidemic situation, sending the personal information to the epidemic situation prevention and control center nearest to the user.
As shown in fig. 2, fig. 2 is a flowchart for determining suspected persons in an epidemic situation according to a first embodiment, and includes:
step S11: when a mobile phone number establishes communication connection with the base station to indicate that a user enters a cell where the base station is located, the base station sends the mobile phone number to the communication platform;
step S12: the communication platform inquires all base stations which establish communication connection with the mobile phone number within a preset time period (generally set according to the longest latency time of the virus, for example, for a new coronavirus, the preset time period is within the past two weeks);
step S13: judging whether the positions of the base stations are in the epidemic situation area, if so, indicating that the user is in the past to the epidemic situation area, then calculating the total connection time length T of the mobile phone number and a single base station or a plurality of base stations in a certain area, and judging whether the total connection time length T is greater than or equal to a first preset time length T1(ii) a Wherein T is1The number of hours can be several hours, for example, 2 to 24 hours, if yes, it indicates that the user stays in an epidemic situation for a long time, and it is necessary to further check whether the user has suspicious symptoms, generally, the suspicious symptoms are mostly fever, so the determination can be made by checking the body temperature of the user;
step S14: the communication platform tracks the geographical position of the user in real time, and a camera at the user's side is taken, wherein the camera is an infrared thermal imaging thermometer and is used for testing the body temperature in a non-contact manner;
step S15: judging whether the body temperature value of the user is greater than a preset temperature, such as 38 ℃;
step S16: and if the body temperature value is higher than the preset temperature, the communication platform marks the user of the mobile phone number as a suspected epidemic person and sends the personal information of the suspected epidemic person to an epidemic prevention and control center closest to the user.
Therefore, suspected epidemic personnel can be judged through the base station connection record and the body temperature.
Further, the obtaining the trace of the suspected persons in the epidemic situation includes:
acquiring the information of the places where the epidemic situation is suspected to live;
the finding of the target person possibly contacting with the suspected epidemic person based on the trace of the suspected epidemic person comprises the following steps:
and searching for target people which are possibly contacted with the suspected epidemic people based on the frequent residence information of the suspected epidemic people.
After the suspected epidemic situation personnel are judged, the track of the suspected epidemic situation personnel needs to be tracked, particularly the residential area of the suspected epidemic situation personnel can be divided into the residential area in the daytime and the residential area in the evening, the residential area corresponds to the workplace and the living area of the suspected epidemic situation personnel respectively, the residential area is confirmed by tracking and monitoring the places which are frequently visited by the suspected epidemic situation personnel in the past several days in the daytime and the evening and have long residence time respectively, then the mobile phone numbers of the people (target personnel) working or living in the residential area are obtained, and a precaution message is sent to remind the people (target personnel) of paying attention to protection, so that virus propagation is reduced, and the epidemic situation is cut off.
Further, the acquiring the information of the places where the suspected persons in the epidemic situation live includes:
tracking and monitoring the mobile phone number of the suspected epidemic personnel to acquire the number of times that the suspected epidemic personnel stay for a period of time in the past is more than N1Geographical location with second and longest dwell time; recording the geographic position as the information of the place where the suspected epidemic situation personnel live;
or, the number of times of acquiring the mobile phone number interactive signaling with the suspected epidemic personnel in the past period of time is more than N2The position of the base station with the longest communication time; and recording the position of the base station as the information of the place where the epidemic situation is suspected to live.
Tracking and monitoring the trace of the suspected epidemic situation personnel mobile phone terminal in the past several days, and recording the position where the stay times in the daytime of the past several days, namely the time period X1: 00-Xn: 00 (for example 8: 00-20: 00), is more than N times and the stay time is longest, wherein N can take a value of 3-7; it may first be determined whether the application in the handset is provided with GPS information and, if so, the geographic location, including street address, company name, cell name, etc., is recorded and named as a standing place 1. If no application can provide GPS data, recording the position of the base station which has the signaling interaction times with the mobile phone number of the suspected persons in the epidemic situation more than N times and has the longest communication time, recording the geographical position of the base station, and naming the base station as a place 1. Similarly, recording the corresponding geographic position in the time period Y1: 00-Yn: 00 (for example, 20: 00-8: 00) at night, and naming as a permanent place 2; thus, a daily place 1 of suspected epidemic people in the daytime and a daily place 2 of suspected epidemic people in the evening are obtained.
Further, the finding of the target person who may contact with the suspected epidemic person based on the frequent residence information of the suspected epidemic person includes:
searching for the personnel staying at the geographical position corresponding to the place of daily living in a second preset time period, and setting the personnel as the target personnel; alternatively, the first and second electrodes may be,
inquiring that the communication stay time of the base station corresponding to the ordinary place is longer than a second preset time T2The user of the mobile phone number is set as the target person. .
The communication management platform stores the places 1 and 2 and inquires about the people staying at the corresponding geographic positions of the places 1 in the time period X1: 00-Xn: 00 and the places 2 in the time period Y1: 00-Yn: 00 in a second preset time period, wherein the second time period can be days or hours in the past; or a period of time from the present; or the communication staying time is longer than a second preset time T2Or the number of the user with the interactive signaling times larger than n, the T2Can be a value in hours, such as 2-10 hours, or 4-6 hours; n can be set to any value greater than 1; and immediately sending a piece of prompting information of suspected persons with epidemic situations in the place 1 or the place 2 to the user group with the user number, asking the user group to do protection work, wearing a mask and paying attention to ventilation.
Further, the obtaining the trace of the suspected persons in the epidemic situation includes:
acquiring a moving track of the suspected epidemic situation personnel;
the finding of the target person possibly contacting with the suspected epidemic person based on the trace of the suspected epidemic person comprises the following steps:
judging whether other people and the suspected epidemic people take the same transportation means or not based on the movement track of the suspected epidemic people; and the number of the first and second groups,
and if other people and the suspected epidemic people take the same transportation means, setting the other people as the target people.
Except that suspected epidemic people are easy to infect surrounding people in daily life, if the suspected epidemic people take public transportation vehicles, such as buses and subways, and are easy to infect the surrounding people in a relatively sealed environment, the suspected epidemic people need to track the track of the suspected epidemic people and then position the moving position of the suspected epidemic people according to a positioning system such as a GPS.
Further, the acquiring the movement track of the suspected persons in the epidemic situation includes:
and recording the real-time geographic position of the mobile terminal held by the suspected epidemic personnel and the base station accessed in real time to form the moving track of the suspected epidemic personnel.
The movement track comprises the steps of acquiring real-time GPS geographical position information of the mobile terminal of the mobile phone number to record displacement change of the mobile terminal, wherein the displacement 1 is S1, the displacement 2 is S2, and the like records S1, S2 and S3 … Sn. And each displacement change records its time information, which corresponds to t1, t2, t3 … tn in turn. Besides the above records, the information of the base station currently accessed by the mobile phone number of the suspected person in the epidemic situation is also recorded. So as to conveniently confirm the users of other mobile phone terminals in the same line.
Further, the determining whether there are other people to take the same transportation vehicle as the suspected epidemic people based on the movement track of the suspected epidemic people includes:
when the real-time geographical position of the mobile terminal held by the suspected epidemic situation personnel is recorded, judging whether the mobile terminal held by other personnel is accessed to the current access base station of the mobile terminal held by the suspected epidemic situation personnel;
if a mobile terminal held by other personnel is accessed to the current access base station of the mobile terminal held by the suspected epidemic situation personnel, recording the real-time positions of the mobile terminals held by the other personnel;
calculating a first degree of identification of the mobile terminal held by the suspected epidemic situation personnel and the mobile terminals held by other personnel at the current real-time position, and judging whether the first degree of identification is more than or equal to 90%;
