Specifically, in order to gather more intelligent terminal's MAC information, internal system can place multiple WIFI module. Each WIFI module has a radio frequency unit and an antenna, and every antenna is intercepted at fixing channel, thus avoids the handover overhead of channel, then improves the scheduling of system detection efficiency simultaneously, also reduces the expense of main control module.
The present invention has gone back the flow chart of the preferred embodiment of a kind of sniff method based on the described real-time sniff system of the intelligent terminal based on WIFI, as it is shown on figure 3, wherein, method includes:
WIFI data of eating dishes without rice or wine are intercepted by step S100, WIFI module on fixed channel, and judge that whether the data intercepted are that the WIFI that intelligent terminal sends eats dishes without rice or wine packet;
If step S200 detects that the data intercepted are that the WIFI that intelligent terminal sends eats dishes without rice or wine packet, then WIFI module parses the mac address information of the WIFI intelligent terminal eated dishes without rice or wine in packet and preserves;
The mac address information of the intelligent terminal of storage is sent to memory module through main control module by step S300, WIFI module every the first predetermined period of time;
The mac address information of the intelligent terminal stored in memory module is sent to background server by step S400, communication module every the second predetermined period of time;
Step S500, background server obtain the mac address information of intelligent terminal, generate intelligent terminal's distribution results of current region, and transmission displays to man-machine display interface.
When being embodied as, by catching management frame (Proberequest, disassociation frame, authentication frame etc.), control frame and the Frame that intelligent terminal sends, and parse what the MAC Address in above-mentioned frame realized. As long as intelligent terminal opens WIFI function, no matter whether they have been coupled to access points, and system all can detect the presence of which. Antenna in WIFI module is only responsible for intercepting WIFI and is eated dishes without rice or wine data, but does not send data. System have employed caching mechanism, and the terminal MAC information of collection is saved in WIFI built-in database by WIFI module.
When being embodied as, also include before described step S100:
Step S10, main control module are by the operational factor of serial ports configuration WIFI module.
When being embodied as, main control module is by parameters such as the fixed channels of serial ports configuration WIFI module. Specifically, when main control module is initially configured serial ports, serial ports is in a receive mode, waiting the configuration information of main control module, as fixed channel, data send the information such as time window, data send time window i.e. the first predetermined period of time, when receiving configuration information, that revises WIFI module intercepts the information such as channel, data transmission time window, and response main control module configuration information has been received by, and continues waiting for main control module configuration data.
WIFI data of eating dishes without rice or wine are intercepted by WIFI module by wherein said step S100 and specifically include:
Step S11, configuration serial ports, arrange display module state, open system clock timer, configure serial ports, makes serial ports be in receiver module, loads WIFI and drives, and opens WIFI and filters word, arranges acquiescence and intercept channel;
Step S12, intercept packet of eating dishes without rice or wine, it is judged that whether receive packet is that WIFI eats dishes without rice or wine packet.
Further, described step S200 specifically includes:
If step S201 detects that the data intercepted are that the WIFI that intelligent terminal sends eats dishes without rice or wine packet, then WIFI module parses WIFI and eats dishes without rice or wine the mac address information of the intelligent terminal in packet;
Step S202, judge whether mac address information has stored in WIFI module, if existing, and last time resolves the time difference of time and current parsing time within the 3rd scheduled time, then former mac address information is replaced with the packet information that the mac address information of current parsing is corresponding, and updates the timestamp information being currently received; If being absent from, the mac address information parsed and the timestamp information that is currently received are stored in a new entry and are saved in WIFI module.
When being embodied as, if be resolved to the MAC Address of repetition in the 3rd T1 scheduled time, WIFI module time, then only need the parsing time that in more new database, this MAC Address is last. Per interval the second predetermined period of time T2 of main control module upload the data to server, and the occasion that the value of T1 and T2 uses according to system is different and is optimized by corresponding algorithm.
If detecting, the data intercepted are that the WIFI that intelligent terminal sends eats dishes without rice or wine packet, then parse intelligent terminal's MAC Address that data include, signal intensity, packet rate information;
Judge whether the MAC Address obtained searches whether identical MAC Address in WIFI chip database, if existing, then substitute packet information corresponding to MAC, update the timestamp information being currently received, if not a then newly-built entry, the information parsed and the timestamp information being currently received are stored in this entry. WIFI data after parsing are stored in the storage data base that WIFI module is built-in, and send to memory module by after the first predetermined period of time.
Further, described step S400 specifically includes:
Step S401, communication module every the second predetermined period of time by memory module storage the mac address information of intelligent terminal sent to background server by wired or wireless mode.
When being embodied as, the information of collection, the information wherein gathered refers to the resolution data that memory module stores. The information gathered can pass through network cable transmission to server, is being inconvenient to the region that connects up, it is possible to wirelessly the data of system acquisition are sent to server end. Main control module the second predetermined period of time reports current packet capturing situation by communication module to server, when judging that the report cycle time arrives, then main control module obtains the intelligent terminal's information captured of storage in memory module, and pack, by communication module, data are sent successively, long data subpackage is sent, until total data has sent, main control module data base empties the information in memory module, waits and calling time on next time.
