Problems solved by technology

[0005] From the principle of trapping, according to the principle of mobile phone sending packets is not fixed wireless related principles, it is not necessarily always sending packets on channel 1 or 11, so there is a high probability that there is a possibility of packet loss; RSSI should not change, but due to the presence of leading frequency interference, it is possible to capture the data of nearby channels, or the current channel data captured in the next 1s is captured after the mobile phone itself switches channels, which will cause changes in the wireless power of the mobile phone , which reflects that the signal strength will fluctuate to a certain extent, which will affect the accuracy of the data and is not conducive to positioning judgment

Embodiment 1

[0037] figure 1 Flowchart of the data acquisition method of the sniffing device of the present invention. The acquisition aspect of the present invention is mainly determined according to the "interference" of the current channel--capturing the quantity of probe request requests, the default primary network card of the sniffing device is 1 channel, and the secondary network card is 11 channels. A method for collecting data from a sniffing device, comprising the steps of:

[0038] S11. The main network card captures the number of detection requests in the messages sent from the terminal in the current channel 1, which is recorded as number1;

[0039] S12. The secondary network card records the number of detection requests captured by the current channel 11, which is recorded as number11;

[0040] S13. The secondary network card starts polling from channel 2 to channel 10, records the number of probe requests captured, and records them as number2~number10, and compares them wi...

Embodiment 2

[0054] Change the step S13 of step example 1, remove the timer processing during the polling period, first carry out packet capture statistics on channel 1 and channel 11, and count them as number1 and number11, then start polling the channel, and replace the main network card channel as polling after the end If the result is channel X, the working channel of the secondary network card stops polling, and collects data normally after changing the channel. The channel selection method can be stipulated as follows: if X+2 10 is recorded, the polling and channel replacement action will be restarted.

[0055] In the 2 wireless frequency bands, there is leading frequency interference between adjacent wireless channels, and increasing the distance between channels can effectively solve this interference problem. Select X channel after polling. In order to reduce interference, use X+2 channel or X-2 channel to work. The difference between the two channels can be balanced between the f...

Embodiment 3

[0058] An embodiment of the present invention also provides a storage medium, the storage medium includes a stored program, wherein, when the above program is running, the process of the above method for collecting data from a sniffer device is executed.

[0059] Optionally, in this embodiment, the above-mentioned storage medium may be set to store program codes for executing the following process flow of the sniffing device data collection method:

[0060] S11. The main network card captures the number of detection requests in the messages sent from the terminal in the current channel 1, which is recorded as number1;

[0061] S12, the secondary network card records the number of detection requests captured by the current channel 11, which is recorded as number11;

[0062] S13. The secondary network card starts polling from channel 2 to channel 10, records the number of probe requests captured, and records them as number2~number10, and compares them with number1 in turn, retai...

Abstract

The invention provides a sniffing equipment data acquisition and processing method, a sniffing equipment data acquisition and processing system, a storage medium and a processor. The data acquisitionmethod comprises the following steps that a main network card captures the number of detection requests in a message sent by a terminal in a current channel 1, and records the number as number1; a secondary network card records the number of the detection requests captured by a current channel 11 and records the number as number11; the secondary network card starts to poll the channel 10 from thechannel 2, records the number of the captured detection requests, records the number of the captured detection requests as number2-number10, compares the number of the captured detection requests withnumber1 in sequence, reserves the maximum value, records the maximum value as nummax1, and the main network card changes the detection channel into the channel with the maximum number of the detection requests; the nummax1 is compared with the number11, wherein the maximum value is nummaxx; before the next polling is finished, the sniffing equipment captures data by adopting the channel with themaximum number of the detection requests of the last polling. According to the method, the user data volume for positioning can be increased, the data validity can be ensured, the positioning precision can be improved, subsequent big data analysis and processing are facilitated, and a good data foundation is laid for subsequent better application.

Description

【Technical field】 [0001] The invention relates to the technical field of data processing, in particular to a method for collecting and processing sniffing data, a storage medium and a processor. 【Background technique】 [0002] WIFI sniffing is a derivative of communication equipment, which is used for offline positioning of users and has great advantages. Unfortunately, due to the policy setting of the data collected by the sniffing device, there is very little effective data that can be used for positioning, and the precise positioning stops at the complex background of the basic data and the unbalanced data volume. [0003] The MAC address is highly bound to the user's identity, valid for a long time, and the MAC address is unique, unless it is artificially changed, it will not change, which shows the importance of the MAC address, and the sniffing device itself grabs the detection The request (probe request) frame occurs before authentication and access to the network.
