Embodiment 1

[0049] Please refer to figure 2, the present embodiment provides a Wifi probe, including the following components:

[0050] The scanning module is used to sequentially scan each Wifi channel in its detection area through a rotary scanning method, and obtain the broadcast data packets of each device in each Wifi channel;

[0051] The data preprocessing module is used to preprocess the broadcast data packets before data upload, remove invalid information and retain valid information; valid information includes collection time, device MAC address and signal strength, invalid information includes broadcast address, CRC , 802.11 standard version, frame type and control type and other information in frame control;

[0052] The data storage module is used to pre-store the preprocessed broadcast data packets in the SD card;

[0053] The data upload module is used to regularly upload the data in the SD card to the server according to the predetermined time, or upload data irregularl...

Embodiment 2

[0056] This embodiment provides a data equalization acquisition system, including:

[0057] The client, specifically each device carried by the user, is wirelessly connected to the wireless router;

[0058] A wireless router for providing Wifi services to clients within its range;

[0059] Wifi probe, its principle structure is as follows figure 2 As shown in , it is used to obtain the broadcast data packets of each device within the detection range by means of round-robin scanning, and upload them to the server;

[0060] The server side is used to receive and store the data information reported by the Wifi probe for analysis and processing.

Embodiment 3

[0062] see image 3 , the present embodiment provides a data equalization acquisition method, comprising the following steps:

[0063] Step S101 , the Wifi probe sequentially scans each Wifi channel in its detection area in a round-robin manner, and obtains broadcast data packets of devices in each Wifi channel.

[0064] The received broadcast data packet includes information such as collection time, device MAC address, signal strength, broadcast address, CRC, 802.11 standard version in frame control, frame type and control type.

[0065] Step S102 , the Wifi probe transmits the collected broadcast data packets to the server, and performs subsequent analysis and processing on the server.

[0066] Since the detection area of ​​the Wifi probe includes a plurality of Wifi channels, and the distribution of devices in each Wifi channel is different, this embodiment uses a rotation method to scan each Wifi channel in turn, by improving the data collection effect of each channel In...

Abstract

The invention discloses a Wifi probe and a data balanced collection system and method. The data balanced collection method includes the steps that the Wifi probe sequentially scans Wifi channels in a detection area of the probe in a rotary mode to obtain broadcast data packages of devices in the Wifi channels; the Wifi probe uploads the obtained broadcast data packages to a server. By means of the rotary scanning mode of the Wifi channels, different scanning time is allocated to different Wifi channels according to a single factor or multiple factors so that the balance degree of data collection can be guaranteed to the largest extent; before the data is uploaded to the server, the data is preprocessed, invalid information in the data is removed, only valid information is kept, the data transmission magnitude can be greatly reduced, the transmission cost is reduced, and subsequent quick and accurate data analysis is benefited.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a Wifi probe, a data equalization acquisition system and method. Background technique [0002] With the advancement and development of science and technology, wireless networks have penetrated into all aspects of our lives. The use of Wifi devices such as mobile phones and tablets has been promoted and developed among the masses. With the popularization and use of Wifi devices, the data collection of Wifi devices Wait for the demand to arise. [0003] For example, taking commercial demand as an example, passenger flow is an indispensable data in the management and decision-making of public places such as shopping centers, large shopping malls, chain stores, airports, and exhibition halls. How to accurately collect data from consumers' smart devices, analyze information after data collection, and provide further service support is very necessary. To meet this demand, Wifi ...
