Before discussing exemplary embodiments in greater detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but could have additional steps not included in the figure.

Example one
Fig. 1 is a flowchart of a close contact processing method provided in an embodiment of the present invention, which is applicable to a case where it is determined whether a user is in close contact based on a near field communication technology, and the method may be executed by a close contact processing apparatus, which may be implemented by software and/or hardware, and may be integrated in an electronic device. As shown in fig. 1, the intimate contact processing method in the present embodiment includes the steps of:
s110, second equipment state information sent by second user equipment is obtained based on a near field communication technology, and near field communication signal strength information between the first user equipment and the second user equipment is detected.
The first user equipment acquires second equipment state information sent by the second user equipment based on a near field communication technology, the near field communication technology can be a Bluetooth communication technology, the user equipment can be mobile equipment capable of realizing near field communication such as a mobile phone and a tablet personal computer, the equipment state information can be screen activation state, equipment model and equipment sensor parameter information, and the method for sending the equipment state information can be a Bluetooth broadcast sending technology. The first user equipment detects inter-device near field communication signal strength information between the first user equipment and the second user equipment, wherein the near field communication signal strength information can be Bluetooth signal strength supported by Bluetooth technology. Exemplarily, in the epidemic situation prevention and control field, the close contact condition of two mobile devices can be judged through the bluetooth broadcast technology, so that the risk of the first user equipment holder is judged, and the rapid and undifferentiated epidemic situation prevention and control work is realized.
In an alternative of this embodiment, it may be combined with one or more of the alternatives of this embodiment. The obtaining of the second device state information sent by the second user equipment based on the near field communication technology may include the following steps A1-A2:
a1, scanning and receiving a Bluetooth broadcast packet sent by second user equipment according to a dynamically set receiving and sending switching frequency; wherein the transceiving switching frequency is dynamically determined according to the risk of contracting a disease of the first user equipment holder.
And step A2, analyzing the Bluetooth broadcast packet received from the second user equipment to obtain second equipment state information sent by the second user equipment.
The first user equipment dynamically sets the receiving and sending switching frequency of the Bluetooth broadcast packet according to the risk of the first user equipment holder, scans and receives the Bluetooth broadcast packet sent by the second user equipment, and analyzes the Bluetooth broadcast packet sent by the second user equipment to obtain the state information of the second equipment. For example, the highest risk value of the user equipment holder may be 900 and the lowest risk value of the user equipment holder may be 0, the broadcast time of the mobile equipment held by the user =10 risk value/3 seconds, and the scan time =300 seconds — broadcast time, and optionally, when the broadcast time of the second user equipment is greater than 5 seconds, the device data information may be reacquired every 5 seconds, the device status information of the second user equipment is updated in real time, and the first user equipment may reacquire the device data information of the first user equipment while receiving the device status information of the second user equipment. When the risk of illness value of the user equipment holder is 0, the broadcast time of the user is 0, and the scanning time is 5 minutes (300 seconds); when the risk of illness value of the user equipment holder is 900, the broadcast time of the user is 5 minutes, and the scanning time is 0. The method has the advantages that the broadcasting time of the low-risk user is shortened, the scanning time is increased, the scanning time of the high-risk user is shortened, the broadcasting time is increased, the reason is that the low-risk user only needs most of time to receive surrounding information because of low risk value, and the high-risk user needs to spend more time to send the broadcasting packet to prompt the surrounding users, so that the effect of real-time accurate epidemic situation prevention and control is achieved.
By adopting the technical scheme, the risk value of the native high-risk user is set by storing and updating the trip, the doctor and the contact data of the user in the server, and then the frequency of transmitting and receiving information of near field communication is determined by the risk value of the user equipment holder, so that the equipment can acquire the equipment state information of other equipment around more frequently, whether close contact exists with the holder of the high-risk user equipment or not can be timely known, epidemic situation monitoring control can be carried out at high timeliness, and the situation that the user is accidentally contacted with an infected patient and cannot be timely known is avoided.
In an alternative of this embodiment, it may be combined with one or more of the alternatives of this embodiment. The device state information comprises at least one of user equipment screen activation state information, user equipment model information and sensor data information acquired by a user equipment sensor. Among them, screen activation state information, device model information, and various sensor data are likely to have a certain correlation with judgment of close contact. Optionally, the device state information of the ue needs to collect data information of various sensors on the ue as much as possible, so that interference factors affecting the strength of the near field communication signal can be analyzed from more dimensions, and the interference factors are introduced in the later ranging process to assist the ranging scheme of the strength of the near field communication signal, thereby improving the accuracy and reliability of ranging.
S120, determining an inter-device contact state between the first user equipment and the second user equipment according to the first device state information, the second device state information and the inter-device near field communication strength information of the first user equipment.
The first user equipment can determine the inter-equipment contact state between the first user equipment and the second user equipment according to the first equipment state information, the second equipment state information and the inter-equipment near field communication strength information of the first user equipment, wherein the near field communication strength information can be Bluetooth signal strength, and the inter-equipment contact state can be whether the inter-equipment contact state is in a close contact range or not, and is an international general regulation; for example, if two people are within 6 feet (182.88 cm) of direct distance, it can be said that the two people are in close contact.
And S130, determining whether the first user equipment holder and the second user equipment holder generate close contact events or not according to the inter-equipment contact state.
The server determines whether the first user equipment holder and the second user equipment holder generate an intimate contact event according to the contact state between the apparatuses, and the intimate contact event is internationally defined as a generation of an intimate contact event when the time during which two persons are cumulatively in an intimate contact state within 24 hours exceeds 15 minutes.
In an alternative of the present embodiment, it may be combined with one or more of the alternatives of the present embodiment. Wherein determining whether the first user equipment holder and the second user equipment holder generate the close contact event may include steps B1-B2:
and B1, calculating the duration time of the two user devices in the close contact state within the preset time according to the inter-device contact state between the first user device and the second user device and the seal judgment timestamp information.
And B2, updating the disease risk value of the first user equipment holder according to the duration of the two user equipment in the close contact state.
The server calculates the duration of the two pieces of user equipment in the close contact state within 24 hours according to the duration of the two pieces of user equipment in the close contact state and the close contact judgment timestamp information, and updates the risk of contracting a disease value of the user equipment holder according to the duration.
By adopting the technical scheme, the risk value of the equipment user is updated according to the continuous time of the close contact state, so that the epidemic situation prevention and control work is passively completed, and the technical effect of checking the risk value of the user in real time can be provided for the user.
According to the technical scheme of the embodiment, second equipment state information sent by second user equipment is acquired based on a near field communication technology, and inter-equipment near field communication signal strength information between first user equipment and the second user equipment is detected; determining an inter-device contact state between the first user equipment and the second user equipment according to first equipment state information, second equipment state information and inter-device near field communication strength information of the first user equipment; according to the inter-device contact state, whether the first user equipment holder and the second user equipment holder generate the close contact event or not is determined, so that the technical effects of reducing errors and interference, more accurately judging the close contact state between users through the distance, updating the disease risk value of the user equipment holder in real time and providing the disease risk value for the users to check are achieved.
Example two
Fig. 2 is a flow chart of another method for close contact processing according to the second embodiment of the present application. The embodiment of the present invention is further optimized based on the foregoing embodiments, and the embodiment of the present invention may be combined with various alternatives in one or more of the embodiments. As shown in fig. 2, the method for processing close contact provided in the embodiment of the present invention may include the following steps:
s210, second equipment state information sent by second user equipment is obtained based on a near field communication technology, and near field communication signal strength information between the first user equipment and the second user equipment is detected.
And S220, inputting the first equipment state information, the second equipment state information and the near field communication signal strength information between the first user equipment into a pre-trained joint sealing judgment model.
The first user equipment inputs the state information of the first user equipment, the state information of the second user equipment and the inter-equipment approach communication signal strength information into a pre-trained joint sealing judgment model, the joint sealing judgment model can be a deep learning model trained through a large number of samples, as shown in a user equipment interaction flow chart in fig. 3, information is sent from the second user equipment to the first user equipment (local machine) to receive the information, the model is input to judge whether joint sealing distance judgment is met or not, and discarded data or contact records are selected to be uploaded to a server. For example, a currently existing method for measuring a distance by using a bluetooth Signal Strength (RSSI) is represented by the following formula: d =10^ (abs (RSSI) -a/(10 × n)) to calculate the resulting distance d. Where a is the signal strength at one meter distance from the bluetooth device and n is the ambient attenuation factor. It can be seen that the value of a will change from model to model of the mobile phone, and the value of n will become unstable if it is simply a constant value. Because various factors, including the orientation of the bluetooth transmitting device, the obstruction, the receiving efficiency of the receiving device, etc., affect the strength of the finally received bluetooth signal in the process of bluetooth propagation, the bluetooth ranging process cannot be simply calculated by using such an equation. Because the interference of various environmental factors cannot be quantitatively and qualitatively analyzed, when the mobile phone screen is in an inactive state, the probability that the mobile phone and the mobile phone are shielded by obstacles such as clothes, bags, human bodies and the like is high, but the strength of the interference cannot be determined, so that the technical scheme of the embodiment adopts deep learning to train relevant variables such as the screen activation state, the mobile phone acceleration, the mobile phone model and the like through a large amount of data sets, and finally obtains a stable and accurate distance monitoring method.
S230, outputting an inter-device contact state between the first user equipment and the second user equipment through the joint sealing judgment model; wherein the inter-device contact state comprises: two user devices are within the close contact distance range and two user devices are not within the close contact distance range.
The contact judgment model may be a two-classifier, which analyzes the input sample according to the training result and outputs 0 or 1, that is, a non-contact state and a contact state.
In an alternative of the present embodiment, it may be combined with one or more of the alternatives of the present embodiment. The inputting the first device status information of the first user equipment, the second device status information, and the inter-device near field communication signal strength information into a seal contact judgment model trained in advance may include steps C1 to C2:
step C1, setting a sealed scene and a non-sealed scene according to the close contact distance definition, collecting at least two device states of user equipment in different scenes, and adding corresponding scene labels; the scene tag is used to characterize whether it is within an intimate contact distance range.
And C2, performing relevance analysis on each equipment state and the scene label, and selecting at least one equipment state with the highest relevance with the scene label to train to obtain the joint seal judgment model.
The close connection judgment model is trained by setting close connection scenes and non-close connection scenes according to close contact distance definitions in advance, acquiring at least two kinds of device state information of user equipment in different scenes, adding corresponding scene labels (close connection or non-close connection) to each kind of device state information, performing association analysis on each kind of device state and the scene labels, and selecting at least one device state with the highest association degree with the scene labels.
By adopting the technical scheme, the contact scene and the non-contact scene are set, the equipment state information is detected and labeled from the corresponding scene, and at least one equipment state with the highest association degree is selected through association degree analysis to train the model, so that the technical effect of improving the training efficiency of the joint sealing judgment model is achieved.
And S240, determining whether the first user equipment holder and the second user equipment holder generate close contact events or not according to the inter-equipment contact state.
According to the technical scheme of the embodiment, the current tight fit state is judged by inputting the acquired first user equipment state data information and the acquired second user equipment state data information into the trained tight fit judgment model, and tight fit and non-tight fit scenes are set to train the model by using the sample with the label, so that the technical effects of improving the training efficiency of the tight fit judgment model and more accurately judging the contact state between the devices are achieved.
