And determining the indoor entering time and the device position of the Bluetooth signal acquisition device as second positioning information. And when a plurality of Bluetooth signal acquisition devices are arranged indoors and the mobile terminal moves to the next Bluetooth signal acquisition device, the next Bluetooth signal acquisition device repeats the steps to generate second positioning information. Thus, a plurality of different times and corresponding different device locations may be included in the second positioning information.
In addition, when the bluetooth signal acquisition devices are deployed indoors, the coverage areas of the bluetooth signal acquisition devices may have overlapping areas, and at this time, the bluetooth signal acquisition device with the highest signal strength connected with the mobile terminal is determined to be the bluetooth signal acquisition device which generates the second positioning information.

since the first positioning information includes the outdoor entry time, the mobile terminal will have the outdoor entry time when entering each mobile network base station, and the outdoor entry time can be sorted from small to large according to the time sequence to obtain the first sequence. I.e. the first sequence is a set of outdoor entry times arranged in chronological order.
And a substep S3022, determining outdoor movement track information based on the first sequence connecting the base station positions.
And after the first sequence is obtained, connecting the base station positions corresponding to the outdoor entry time of each element bit in the first sequence according to the sequence in the sequence, and determining the base station positions as outdoor movement tracks. I.e. the outdoor trajectory of the mobile terminal carrier is described in the sequence of its movements.

The storage location may be a storage space of the cloud platform itself, or may be a third-party data storage space connected to the cloud platform, which is not specifically limited in this embodiment of the present invention.
after the tracing information is generated, when a manager or an individual needs to determine whether a person on a certain track is at risk of epidemic infection, the track can be used as a reference track, and the reference track can comprise at least one of an indoor track and an outdoor track. Generating a matching request according to the reference track and sending the matching request to the cloud platform; the cloud platform receives the matching request.
the distance between each position point in the tracing information and the same time space is the same time space distance based on the reference track. For example, if the indoor entry time of the position point a in the tracing information is 12 minutes, then correspondingly 30 minutes after 12. It should be noted that the same-time-space distance can be calculated by comparing all the position points of the tracing information with the reference trajectory.
the distance threshold is set in combination with the spatiotemporal adjoint characteristic of virus propagation, and a virus infection risk may exist in a range of the linear distance threshold, for this reason, the size of the co-spatiotemporal distance and the preset distance threshold may be determined, and the determination manner may be a difference method, a comparison method, a numerical axis method, or the like, which is not specifically limited in the embodiment of the present invention.
When the space distance of any position point of the tracing information is smaller than a preset distance threshold value, namely the tracing information is close to the reference track, the personnel corresponding to the tracing information have infection risks, and the tracing information is determined to be target information.
And step 308, sending the target tracing information.
After the target tracing information is determined, the target tracing information can be sent to a manager, and the manager performs corresponding epidemic prevention measures on the target tracing information. The target tracing information can also be pushed to the personnel corresponding to the target tracing information, the personnel are determined to be close contact personnel, and the personnel are informed to wait for the epidemic prevention work to be processed at home. And the close contact persons are assigned to various communities according to the addresses of the close contact persons. And generating the epidemic situation risk degree of a certain cell, community or street according to the addresses of the closely contacted people, and providing data support for formulating an epidemic prevention policy.

And S6, deleting the tracing information when the time difference value is greater than a preset time threshold value.
When the time difference is greater than the preset time threshold, it may be determined that the valid time of the tracing information has passed, and the tracing information may be deleted in order to avoid occupying too much storage space and reducing data processing amount.
According to the embodiment of the invention, the indoor track is recorded by arranging the Bluetooth signal acquisition equipment indoors, and the outdoor track is recorded by integrating the outdoor mobile network base station, so that the track tracking is more comprehensive, and the accuracy and the rapidness of epidemic prevention traceability can be effectively improved; the effective days recorded on the cloud platform can be dynamically adjusted according to epidemic prevention policies, close contact ranges are comprehensively analyzed in combination with virus transmissibility, and close contact personnel are screened, so that epidemic prevention management is more scientific, and responsibility is more clear; and only need add the supplementary indoor location of bluetooth signal acquisition equipment in personnel intensive place, other functions all can be realized in current mobile communication network, and the implementation scheme is economical and feasible, easily promotes.
