Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of an embodiment of a method for determining target information based on a WIFI probe according to the present invention, and as shown in fig. 1, the method for determining target information based on a WIFI probe according to the embodiment of the present invention includes the following steps:
s101: receiving information respectively sent by all WIFI probes in a target area; each piece of information carries the MAC address to be detected corresponding to each terminal, the distance between each terminal and each MAC address to be detected, and the position information of each terminal, which are detected by each WIFI probe; the target area includes at least three WIFI probes.
Specifically, the device receives information respectively sent by all WIFI probes in a target area; each piece of information carries the MAC address to be detected corresponding to each terminal, the distance between each terminal and each MAC address to be detected, and the position information of each terminal, which are detected by each WIFI probe; the target area includes at least three WIFI probes. The device may be a server performing the method, and the server may be networked with all WIFI probes. The terminal may comprise a user terminal, such as a cell phone used by a customer, and the target area may be a sub-area of a public area, the sub-area deploying at least three WIFI probes. The position information of the WIFI probe itself may be a position coordinate of each WIFI probe, and is not particularly limited.
The MAC address to be tested may include a real MAC address and a pseudo MAC address, and it is understood that: each mobile phone corresponds to a unique real MAC address which is fixed and invariable, namely, the real MAC addresses of the same terminal detected by each WIFI probe are the same, and the same WIFI probe detects the real MAC addresses in different waysThe real MAC addresses of the same terminals detected periodically are also the same. For mobile phones of different models, pseudo MAC addresses can also be provided, and the pseudo MAC addresses are not fixed, that is, the pseudo MAC addresses of the same terminal detected by each WIFI probe are different, and the pseudo MAC addresses of the same terminal detected by the same WIFI probe in different detection periods are also different. The distance between one of the WIFI probes PA and one of the terminals UE1 is denoted as dA1，dA1Can be calculated according to the following formula:
dA1＝10(A-RSSI)/n
where a represents a signal strength at a distance of one meter, a Received Signal Strength Indication (RSSI), and n represents an attenuation coefficient. Calculating the distance between each WIFI probe and each terminal, and referring to the dA1The calculation process of (2) is not described in detail.
For example, the target region has p WIFI probes and q terminals in total, where p is greater than or equal to 3, q is greater than or equal to 1, for example, q is 2, the two terminals are respectively denoted as UE1 and UE2, if the MAC address to be measured corresponding to UE1 is a real MAC address a1 (no pseudo MAC address exists in UE 1), and the MAC address to be measured corresponding to UE2 is a real MAC address a2 and a pseudo MAC address (different pseudo MAC addresses detected by different WIFI probes are different), the information sent by the WIFI probe PA carries a1, a2, and a21 (the pseudo MAC address detected by the WIFI probe PA is UE 2); dA1、dA2(ii) a The location information XA of the WIFI probe PA, XA may mark that the location information is of the WIFI probe PA. Taking three WIFI probes as an example, the information sent by the WIFI probe PB carries a1, a2, a22 (UE2 pseudo MAC address detected by the WIFI probe PB); dB1、dB2(ii) a Position information XB, XB of WIFI probe PB can mark that this position information is of WIFI probe PB. The information sent by the WIFI probe PC carries A1, A2 and a23 (UE2 pseudo MAC address detected by the WIFI probe PC); dC1、dC2(ii) a The position information XC and XC of the WIFI probe PC can mark that the position information is of the WIFI probe PC.
S102: detecting all MAC addresses to be detected, and determining a target MAC address according to a detection result; the target MAC address is the same real MAC address detected by all the at least three WIFI probes.
Specifically, the device detects all MAC addresses to be detected, and determines a target MAC address according to a detection result; the target MAC address is the same real MAC address detected by all the at least three WIFI probes. Referring to the above example, a1 is the same real MAC address detected by the WIFI probe PA, the WIFI probe PB, and the WIFI probe PC, and a2 is the other same real MAC address detected by the WIFI probe PA, the WIFI probe PB, and the WIFI probe PC, so that a1 and a2 are both target MAC addresses, and a21, a22, and a23 are all detected by only one WIFI probe, and therefore are not target MAC addresses. It should be noted that: due to the fact that the pseudo MAC address is not fixed and unchangeable, the pseudo MAC address can be removed through the step, the real MAC address detected by two WIFI probes or one WIFI probe is also removed, and therefore data are cleaned through the step, a large amount of data corresponding to the non-target MAC address are removed, calculation of the subsequent step is not involved, and calculation amount in determining the target information is reduced.
S103: if the target MAC address is judged and found to be detected by all the at least four WIFI probes, determining the WIFI probes to be selected corresponding to the three target distances with the shortest distance to be selected as target WIFI probes according to the distance to be selected of the target terminal corresponding to the target MAC address and each WIFI probe to be selected, and determining the target position information and the target distance of each target WIFI probe as target information; the WIFI probe to be selected is each WIFI probe in the at least four WIFI probes and the target MAC address is detected.
Specifically, if the device judges that the target MAC address is detected by all of at least four WIFI probes, determining the WIFI probes to be selected corresponding to the three target distances with the shortest candidate distance as target WIFI probes according to the candidate distance between the target terminal corresponding to the target MAC address and each WIFI probe to be selected, and determining the target position information and the target distance of each target WIFI probe as target information; the WIFI probe to be selected is each WIFI probe in at least four WIFI probes for detecting the target MAC addressAnd (3) a needle. On the basis of the above example, a WIFI probe PD is added, and the information sent by the WIFI probe PD carries a2 (that is, a1 corresponding to the UE1 is not detected by the WIFI probe PD), a24 (the UE2 pseudo MAC address detected by the WIFI probe PD); dD1、dD2(ii) a Position information XD of the WIFI probe PD, and the XD can mark that the position information is that of the WIFI probe PD. Taking UE2 as an example, a2 is detected by all of WIFI probes PA to PD, and therefore, each WIFI probe to be selected corresponding to UE2(UE2 is a target terminal corresponding to a 2) is: WIFI Probe PA ~ WIFI Probe PD. At a candidate distance dA2、dB2、dC2、dD2In the step (d) if the shortest candidate distance isA2、dB2、dC2Then the target distance is dA2、dB2、dC2. The target WIFI probes are WIFI probes PA-PC. The target information is: position information XA and target distance d of WIFI probe PAA2(ii) a Position information XB and target distance d of WIFI probe PBB2(ii) a Position information XC and target distance d of WIFI probe PCC2。
According to the method for determining the target information based on the WIFI probe, provided by the embodiment of the invention, the target MAC address is determined by detecting all the MAC addresses to be detected, the target WIFI probe is determined according to the shortest distance principle, and then the target position information and the target distance of each target WIFI probe are determined as the target information, so that the target information can be conveniently determined based on the WIFI probe.
On the basis of the above embodiment, the detecting all MAC addresses to be detected and determining a target MAC address according to a detection result includes:
and acquiring the occurrence frequency of each MAC address to be detected in all the MAC addresses to be detected, and rejecting the MAC addresses to be detected, wherein the occurrence frequency of the MAC addresses to be detected is less than or equal to two times.
Specifically, the device obtains the occurrence frequency of each MAC address to be detected in all MAC addresses to be detected, and eliminates the MAC addresses to be detected with the occurrence frequency less than or equal to two times. Referring to the above example, taking three WIFI probes PA to PC as examples, the occurrence frequency of a21 to a23 is one time, so a21 to a23 are eliminated.
And determining the target MAC address in the remaining MAC addresses to be tested.
Specifically, the device determines the target MAC address among the remaining MAC addresses to be tested.
Referring to the above example, the remaining MAC addresses to be tested are a1 and a2, and are all detected by the WIFI probes PA to PC, and therefore, a1 and a2 are both determined as target MAC addresses.
According to the method for determining the target information based on the WIFI probe, provided by the embodiment of the invention, the MAC address to be detected with the occurrence frequency less than or equal to two times is removed, so that data cleaning is efficiently realized, and the target information can be further conveniently determined based on the WIFI probe.
On the basis of the above embodiment, the determining the target MAC address from the remaining MAC addresses to be tested includes:
and determining the target MAC address in the remaining MAC addresses to be tested by adopting a polling mode.
Specifically, the device determines the target MAC address in the remaining MAC addresses to be tested in a polling manner. The sequencing of the remaining MAC addresses to be detected (which may be according to the detection order of the WIFI probes PA to PC) may be a1 and a2 (the first group corresponds to the WIFI probe PA); a1, a2 (second set, corresponding to WIFI probe PB); a1 and a2 (a third group corresponding to the WIFI probe PC), a1 is found in the first group, whether a1 still exists is sequentially found in other groups, and the number of occurrences of a1 is counted, for example, the number of occurrences of a1 is three for each of the second group and the third group a1, and therefore, it is determined that a1 is the target MAC address, and the description of a2 may refer to a1, which is not described again.
According to the method for determining the target information based on the WIFI probe, provided by the embodiment of the invention, the target MAC address is determined in a polling mode, and the data query process is further optimized, so that the target information can be further conveniently determined based on the WIFI probe.
On the basis of the above embodiment, the method further includes:
and if the target MAC address is judged and found to be detected by all the three WIFI probes, determining the three WIFI probes which detect the target MAC address as the target WIFI probes.
Specifically, if the device judges that the target MAC address is detected by all three WIFI probes, the three WIFI probes that detect the target MAC address are determined to be the target WIFI probes. Referring to the above example, for the UE1, since the a1 is not detected by the WIFI probe PD, the a1 is detected by all of the WIFI probes PA to WIFI probes PC, and since the position coordinates reflecting the position of the customer need to be calculated by a three-point positioning method, this example only has three WIFI probes, and therefore, the distance does not need to be compared, the WIFI probes PA to WIFI probes PC are directly determined as target WIFI probes, and the step of determining the target information based on the distance does not need to be described again with reference to the above description.
According to the method for determining the target information based on the WIFI probe, provided by the embodiment of the invention, for the condition that the target MAC address is detected by all three WIFI probes, the target information can be determined more quickly based on the WIFI probe.
On the basis of the above embodiment, the receiving of the information respectively sent by all WIFI probes in the target area includes receiving information respectively periodically sent by all WIFI probes in the target area; correspondingly, the method further comprises the following steps:
and carrying out synchronization processing on the received periodically transmitted information.
Specifically, the device synchronizes the received periodically transmitted information. On the basis of the information respectively sent by each WIFI probe, each piece of information can also carry the reporting time T sent to the server, and the reporting times T can be recorded as TA-TC for the WIFI probes PA-PC respectively. Because each WIFI probe respectively sends information periodically according to the detection time interval (denoted as tA to tC), tA to tC may be inconsistent, and therefore tA to tC received by the server may also be inconsistent, a threshold TS may be set, so that all WIFI probes will be detected completely within TS seconds, that is, all WIFI probes in the next round are started to detect at every interval of one synchronization processing time interval TS, and the synchronization processing time interval TS may be greater than the maximum detection time interval of tA to tC, and may be selected as 300 seconds.
According to the method for determining the target information based on the WIFI probe, provided by the embodiment of the invention, the received periodically sent information is subjected to synchronous processing, so that the execution synchronism of the method is ensured.
On the basis of the above embodiment, the detecting all MAC addresses to be detected and determining a target MAC address according to a detection result includes:
periodically detecting all MAC addresses to be detected, and determining a target MAC address according to a detection result; and the periodic interval for periodically detecting all MAC addresses to be detected is a time interval for synchronous processing.
Specifically, the device periodically detects all MAC addresses to be detected, and determines a target MAC address according to a detection result; and the periodic interval for periodically detecting all MAC addresses to be detected is a time interval for synchronous processing. Referring to the above example, the step of detecting all MAC addresses to be detected once every TS interval and determining the target MAC address according to the detection result is performed. For example, in a time interval TS of a first synchronization process, the received information periodically transmitted by all WIFI probes in the target area is stored in the data table 1, in a time interval TS of a second synchronization process, the information periodically transmitted by all WIFI probes in the target area of a next cycle is received, meanwhile, the data stored in the data table 1 is copied to the data table 2, and in the data table 2, all MAC addresses to be tested in the time interval TS of the first synchronization process are detected, so that the information is periodically received, and all MAC addresses to be tested in the information are detected.
According to the method for determining the target information based on the WIFI probe, provided by the embodiment of the invention, the execution efficiency of the method is further improved on the basis of ensuring the execution synchronism of the method.
On the basis of the above embodiment, the terminal further includes a network device terminal; correspondingly, the detecting all the MAC addresses to be detected and determining the target MAC address according to the detection result includes:
detecting all MAC addresses to be detected by adopting an OUI table; the OUI table prestores preset real MAC addresses corresponding to preset network device terminals.
Specifically, the device adopts an OUI table to detect all MAC addresses to be detected; the OUI table prestores preset real MAC addresses corresponding to preset network device terminals. An organization unique identifier (OUI for short). It should be noted that: all MAC addresses to be tested herein also include MAC addresses of network device terminals, and the network device terminals may include routers and the like, and are not particularly limited. That is, the OUI table stores in advance the correspondence between the preset network device terminal and the preset real MAC address, for example, the router 1 to the preset real MAC address R1, the router 2 to the preset real MAC address R2, and the like.
And if a target MAC address to be detected corresponding to the preset real MAC address is detected, eliminating the target MAC address to be detected, detecting all the residual MAC addresses to be detected, and determining the target MAC address according to the detection result.
Specifically, if the device detects a target MAC address to be detected corresponding to the preset real MAC address, the device rejects the target MAC address to be detected, detects all remaining MAC addresses to be detected, and determines the target MAC address according to the detection result. Examples are as follows: if it is detected that R1 and R2 exist in all the MAC addresses to be tested, since the preset real MAC addresses R1 and R2 correspond to the router 1 and the router 2, respectively, it is recognized that R1 and R2 are the MAC addresses to be tested of the router 1 and the router 2, that is, the MAC addresses to be tested of the routers are determined as the target MAC addresses to be tested, and the target MAC addresses are removed, so that all the remaining MAC addresses to be tested are the MAC addresses to be tested of the user terminal. The description of detecting all MAC addresses to be detected for the user terminal and determining the target MAC address according to the detection result may refer to the above description, and will not be described again.
According to the method for determining the target information based on the WIFI probe, provided by the embodiment of the invention, the target information can be further rapidly determined based on the WIFI probe by removing the MAC address of the network equipment terminal.
