Embodiment 1

[0038] A user close contact tracking system based on radio frequency technology, see figure 1 , including a cloud server, multiple mobile terminals and multiple acquisition devices;

[0039] The collection device is used to collect the distance from surrounding collection devices using radio frequency signals, and send the collected distance, collection time and collection device ID of the collected party to the mobile terminal;

[0040] Specifically, each user is configured with a collection device, and each collection device is configured with a collection device ID. The collection device is used to regularly upload the contact information of the contact user, including distance, collection time and collection device ID of the collected party.

[0041] The mobile terminal is used to send the received distance, collection time and collection device ID of the collected party to the cloud server;

[0042] The cloud server is used to obtain the collection device ID of the coll...

Embodiment 2

[0049] Embodiment 2 On the basis of Embodiment 1, the following content is also added:

[0050] The mobile terminal is also used to initiate a query request including the collection device ID to be queried and the query time to the cloud server; the mobile terminal is also used to display the collection device ID or corresponding user identity information returned by the cloud server;

[0051] The cloud server is configured to, when receiving the query request, obtain the collection device ID whose distance to the collection device corresponding to the collection device ID to be queried is smaller than the preset value within the query time, and send the collection device ID or corresponding user identity information is returned to the mobile terminal.

[0052] Specifically, the cloud server also provides a query function. Users can set preset values ​​according to their own conditions, and users can also query the users they have been in close contact with for a period of ti...

Embodiment 3

[0059] Embodiment 3 On the basis of the foregoing embodiments, the following content is added:

[0060] see figure 2 , during the acquisition tracking time, all collection device IDs corresponding to the collection device ID to be tracked whose distance to the collection device is smaller than the preset value, and defining the user corresponding to the collection device ID as a close contact specifically includes:

[0061] S1: Define the collection device ID to be tracked in the tracking command as the tracking user;

[0062] S2: Obtain the IDs of all acquisition devices within the tracking time and whose distance to the tracking user is less than the preset value;

[0063] S3: Whether the acquired acquisition device ID is empty; if yes, execute step S4; if not, execute step S5;

[0064] S4: the tracking process ends;

[0065] S5: Define the users corresponding to the acquired collection device IDs as close contacts and tracers, and repeat step S2.

[0066] Specifically,...

Abstract

The invention provides a user close contact tracking system based on a wireless radio frequency technology. The user close contact tracking system comprises a cloud server, a plurality of mobile terminals and acquisition equipment, wherein the acquisition equipment acquires the distance between the acquisition equipment and the surrounding acquisition equipment by using a wireless radio frequencysignal, and sends the acquired distance, the acquisition time and the acquisition equipment ID of the acquired party to the mobile terminals; the mobile terminals send the data uploaded by the acquisition equipment to the cloud server; the cloud server acquires an acquisition equipment ID of an acquisition party corresponding to the uploading mobile terminal, associates the data uploaded by the acquisition equipment with the acquisition equipment ID of the acquisition party and then stores the data; and when a tracking/query/retrieval instruction containing the tracking time and the to-be-tracked acquisition equipment ID is received, the system acquires all the acquisition equipment IDs of which the distances to the to-be-tracked acquisition equipment ID are less than a preset value withinthe tracking time, and defines the acquisition equipment IDs as close contacts. The system improves the accuracy of close contact tracking of the user and has a good tracking effect.

Description

technical field [0001] The invention belongs to the field of radio frequency and electronic technology, and in particular relates to a user close contact tracking system based on radio frequency technology. Background technique [0002] In order to more effectively suppress the spread of infectious diseases, users need to maintain a safe social distance during the high incidence of infectious diseases to better reduce the risk of infection. [0003] At present, most user close contact tracking systems on the market use the method of active reporting to track, that is, users actively report the places they have been to, so that when a user is infected, the information of users who have been to the place within a certain period of time is obtained. At that time, due to the relatively high mobility of users, it was difficult for this user close contact tracking system to track all the contact groups of an infected person and who these contacted groups later came into contact wi...
