Description
Technical field：
The invention belongs to flow of the people intelligent detection equipment technical fields, are related to a kind of flow of the people inspection based on WIFI technologies
Device is surveyed, the mac address information of electronic equipment is monitored using the probe for being integrated with WiFi (Wireless Fidelity) module, is taken by converging
Business device integrates MAC (message authentication code) information analyses and draws flow of the people hotspot map.
Background technology：
With the outburst in the markets WiFi, WiFi probe techniques also gradually increase in the application of every field, and WiFi is a kind of
Allow electronic equipment to be connected to the technology of a WLAN (WLAN), is penetrated usually using 2.4G UHF or 5G SHF ISM
Frequent section, be connected to WLAN be typically have cryptoguard, but can also be it is open, allow in this way it is any
Equipment within the scope of WLAN can connect, and WiFi is the brand of a wireless network communication technique, is held by WiFi alliances,
Purpose is the intercommunity improved between the Wi-Fi product based on 802.11 standards of IEEE, WiFi using
IEEE802.11 protocol suites, the sub-protocol that IEEE802.11 protocol suites include develops sequentially in time mainly to be had：
802.11a, 802.11b, 802.11g and 802.11n.In network communications, data have been packaged into frame, and frame refers to just in communication
A data block, frame data-link layer transfer when have set form, as shown in Figure 4：Frame is not careless encapsulation
It can be transmitted with being packaged, size is restricted, and the encapsulation of frame must comply with the rule of minimum 46 bytes and maximum 1500 bytes, with
For 802.11 frame structure (as shown in Figure 5)：There are three types of types for frame in 802.11：Management frame (Management
Frame, such as Beacon frames and Probe Request frames), control frame (Control Frame, for example, RTS frames, CTS frames and
ACK frames) and data frame (Data Frame, carry the carrier of data, and DS fields therein are used for identifying direction critically important), frame
It can identify which field the frame belongs in type field in head.
The relevant frame of WiFi probe techniques includes management frame and data frame, and management frame includes beacon frame and probe request：
Beacon frame (BeaconFrame) is considerable maintenance mechanism, is primarily used to declare some AP (wireless access points)
The presence of network, the beacon periodically sent can allow mobile WiFi equipment to learn the presence of the network, so as to adjust the network is added
Necessary parameter.In basic network, AP must be responsible for sending Beacon frames, and range is basic clothes to Beacon frames in one's power
It is engaged in region, in basic type network, all communications all must be by access point, and WiFi equipment cannot be apart from too far, otherwise as a result,
Beacon can not be received；WiFi equipment scans in region which has using probe request (Probe Request)
802.11 network；It, will when access point will send out the information transmitted before a frame need not still confirm to WiFi equipment
Using the data frame (Data) of standard, the data frame of standard can't consult whether other side has data to be passed, not allow receiving terminal
Transmit any data, data frame used in clear data (Data-Only) frame and uncontended periods used in uncontended periods
It is identical.
The operation principles of WiFi probes as shown in fig. 6, WiFi probes are exactly an AP in fact, its timing to oneself
Surrounding broadcast transmission Beacon frames, for notifying that neighbouring WiFi equipment, AP are existing, meanwhile, WiFi equipment (such as mobile phone
With tablet computer etc.) probe frames are also ceaselessly sent, it looks for nearby available AP, probe frames and contains the mac of equipment
Address just obtains the MAC Address of this equipment after AP receives probe frames, and AP is exactly WIFI probes, is based on this,
As long as the equipment in WiFi probes overlay area opens WiFi, probe can be collected into the MAC Address of equipment.It is being not connected to
In the case of WiFi, mobile device can only send probe frames, and can not access network by probe at this time carries out data transmission,
Probe can only receive the probe frames of WiFi equipment transmission, collect the MAC Address that probe frames carry, be collected into information
It is other information in absolute unrelated userspersonal information and equipment.Probe does not provide function of surfing the Net, between user and probe
Data traffic is only limited to send in probe and be broadcasted, a mobile device connection request of transmission, and phone number, address name, gender
Etc. the details of personal information and equipment be all not included in the inside；But WiFi, with regard to different, WiFi provides online work(
Can, when user is surfed the Internet with it, all flows of user are all that WiFi can see, and have the individual of user inside the content of flow
Information.Since probe design itself is only what equipment detection periphery has, mass data is not generated, design when does not have
There are the data that will be collected into be stored in itself, but be sent directly on central server by wired connection, accordingly even when having
The people of malice takes probe away, can not obtain the information that probe is collected into, while wired connection also ensures data transmission procedure
The form for not easily passing through electromagnetic wave is monitored and steals.Central server is typically all in IDC (Internet data center) computer room
In, and to need layer by layer to permit by IDC into IDC computer rooms.Thus, it whether the transmission of data or stores, probe
Data be all safe.It is individually to be monitored detection, and week can only be detected in WiFi probes in the prior art
Corresponding flow of the people is enclosed, cannot more accurately judge the specific location of the client, also multiple WiFi probes do not cooperate
It uses.Therefore, a kind of WiFi probe units of intelligent Pedestrian flow detection and auxiliary positioning of R ＆ D design, by multiple WiFi probes
Mutually be linked use, to solve signal blind zone, improves accuracy, realizes flow of the people in the large spaces places such as office building, auditoriums, hotels
Auxiliary positioning, have good economic and social benefit, it is very promising.
Invention content：
It is an object of the invention to overcome disadvantage of the existing technology, seek to design a kind of intelligent Pedestrian flow detection and
Multiple WiFi probes and convergence server are mutually linked uses by the WiFi probe units of auxiliary positioning, realization large building
Etc. the auxiliary positioning of flow of the people and the analysis of flow trace in large spaces place.
To achieve the goals above, the agent structure packet of the population flow detection device of the present invention based on WiFi technology
It includes：Upright bar, WiFi probes, PC (personal computer) host, network interface card and convergence server；The top of the upright bar of rod-like structure is arranged
