Embodiment one:
The method that a kind of pair of concealment electronic equipment is detected is present embodiments provided, as shown in Figure 1, including following step
It is rapid:
S1, detection device obtain the wireless signal information in setting range, key message are extracted from wireless signal information,
And key message is directly or indirectly sent to remote server；
S2, remote server carries out analysis matching to key message and obtains matching result, and matching result is fed back to intelligence
It can terminal；
S3, intelligent terminal obtain whether having concealment electronic equipment in setting range according to matching result；
S4 sends command information to detection device if intelligent terminal obtains having concealment electronic equipment in setting range；
S5, detection device calculate concealment electronic equipment according to the concealment electronic equipment near command information monitoring
Distance, and distance is fed back into intelligent terminal.
Wherein, in the step S1, detection device obtains the wireless signal information in setting range, from wireless signal information
Middle extraction key message, specifically:
All types of radio-signal data packets in all channels in the detection device reception setting regions；By data
Packet carries out caching queuing；According to the sequence that caching is lined up, it is successively read the frame header information of each frame in data packet；From frame head portion
Key message is extracted in information；The key message includes the target MAC (Media Access Control) address of frame and the source MAC of frame.
Detection device in the present embodiment uses ESP mould group, and ESP mould group has WIFI and bluetooth simultaneously, and both are communicated
The mode that WIFI module receives signal is changed to Promiscuous Receive by function, the program in detection device, regardless of format, what
Channel, what type, what address, detection device detect all types of radio-signal data packets.Detection device is to acquisition
Data packet queuing processing is carried out according to IEEE802.11 protocol suite, therefore WIFI is using IEEE802.11 protocol suite, this
Protocol suite includes many sub-protocols, and in network communications, data have been packaged into frame, and frame just refers to a data in communication
Block.Because frame head portion is in plain text (unencryption), can to directly read the information in frame head portion, the information in frame head portion includes frame
Target MAC (Media Access Control) address, source MAC, frame type, the frame subtype of frame etc..Detection device is lined up according to caching in this implementation
Sequentially, key message (the i.e. source MAC of the target MAC (Media Access Control) address of frame and frame is successively extracted from the frame header information of each frame
Location).
Key message directly can be sent to remote server by detection device, and key message can also be sent to intelligent end
End, is sent to remote server for key message by intelligent terminal.
Wherein, in the step S2, remote server carries out analysis matching to key message and obtains matching result, specifically
Are as follows:
The remote server is by the source MAC of target MAC (Media Access Control) address and frame in key message, respectively and in database
MAC Address matched, and obtain matching result；
If successful match, matching result is the particular mac address of successful match, if matching is unsuccessful, matching result
For nothing.
In the present embodiment, the database includes the MAC Address of several network hardwares, and each network hardware has unique
MAC Address.Because different network hardware manufacturers possesses the mutual unduplicated MAC Address section of IEEE tissue distribution, and
Consolidated network hardware vendor is provided with different MAC Address to each electronic equipment, it is possible to directly be inquired by MAC Address
Corresponding network hardware manufacturer and corresponding network electronic devices.MAC Address is typically expressed as 12 16 system numbers, two 16 into
It is separated between number processed with colon, such as: 08:00:20:0A:8C:6D is exactly a MAC Address, wherein 16 system number of first six digits,
08:00:20 represents the number of network hardware manufacturer, it is distributed by IEEE, then six 16 system numbers by network hardware manufacturer from
Row layout ensures that each network electronic devices have unique MAC Address in the world in this way.The present embodiment passes through system
The approach such as the mac address informations of concealed electronic equipment such as pinhole cameras are counted, the data of high risk MAC Address are constructed
Library.
The present embodiment is by key message: the target MAC (Media Access Control) address of frame and the source MAC of frame, and already present in database
MAC Address is matched,.If the target MAC (Media Access Control) address of frame or the source MAC of frame are identical as a certain MAC Address in database,
Then successful match then obtains the particular mac address of successful match, that is to say, that nearby there are particular mac address pair for detection device
The electronic equipment answered.It is nothing in matching result if matching is unsuccessful.Therefore, intelligent terminal can be obtained by according to matching result
Whether concealment electronic equipment is had in setting range, if so, the then subsequent distance for calculating electronic equipment.

Distance where covering property electronic equipment, specifically:
The detection device obtains the particular mac address for needing to be monitored according to command information, and detection device is switched to
Monitoring pattern receives the radio-signal data packet that the corresponding concealment electronic equipment of particular mac address issues, according to radio
Signal packet obtains the signal strength that concealment electronic equipment is transmitted, and calculates concealment electronic equipment according to signal strength
Distance.
In the present embodiment, user is known that nearby whether there is electronic equipment by the display content of intelligent terminal, when having
When electronic equipment, intelligent terminal sends command information to detection device, which includes particular mac address, detection device
It receives and automatically switches operating mode after command information, under new operating mode, it is corresponding that detection hardware only receives particular mac address
Concealment electronic equipment issue data packet (data packet not only includes above-mentioned frame header information, further include channel, letter
The information such as number intensity), the signal strength of the corresponding concealment electronic equipment of particular mac address is obtained from the data packet.By
Physical distance between WIFI signal intensity and two communication equipments there are inverse correlation relationship, the relationship of the two can be summarized as with
Lower calculation formula:
D=10^ { [abs (rssi)-A]/(10*n) }；
Wherein: d indicates distance, and abs () indicates that ABS function, rssi indicate that received signal strength, A are to indicate transmitting terminal
Signal strength (A is constant, general value 51) when being separated by 1 meter with receiving end, n indicate the environmental attenuation factor (n is constant, one
As between value 3.25-4.5).
Therefore, detection device is calculated according to the signal strength of the data packet constantly obtained by above-mentioned formula, so that it may
To obtain the distance between concealment electronic equipment and detection device, and the distance is fed back into intelligent terminal and is shown, into
And the specific location for guiding user step by step to conceal the concealed electronic equipment such as pinhole cameras.
In conclusion whether the present embodiment can not only judge nearby to have hiding by the detection and analysis to wireless signal
Property electronic equipment, and the far and near distance of hiding electronic equipment can be calculated, and then help citizen's discovery existing illegal nearby
The electronic equipment of individual privacy is stolen, guidance citizen, which finds, conceals nigh hiding electronic equipment, to prevent citizen's
Individual privacy is stolen.
