Embodiment
With reference to figure 1, the wifi method of attachment of a kind of near field of the present invention authentication-exempt, comprises the following steps:
S1, the MAC Address of terminal of access and signal strength signal intensity to be detected and record in real time;
S2, according to detecting the multiple signal strength signal intensities obtained in real time, draw the relative distance of its correspondence and record, and then draw the mobile route of terminal of access;
The mobile route that S3, basis draw, judges whether it meets the access prescribed profile preset, and if so, then gives this terminal and connects authority and be recorded in permissions list by its MAC Address; Otherwise, then this terminal is not given and connects authority.
Wherein, when fast mobile terminal within the scope of wifi access point, signal strength signal intensity can change, and by tracer signal Strength Changes, can learn the relative distance of each terminal apart from access point, if even can roughly locate when having multiple access point.
Be further used as preferred embodiment, also include before described step S1:
S0, detect the MAC Address of terminal of access whether in permissions list, if so, then directly give corresponding connection authority to this terminal; Otherwise, then step S1 is performed.
Be further used as preferred embodiment, described step S1 also comprises:
Adjustment to the terminal transmit power of this access and the frequency range of tranmitting frequency, and then determines terminal relative position.
Wherein, when there is the terminal of multiple access, access point, by the terminal adjustment transmitting power for each access, adjusts the frequency range of self, the terminal of other accesses can carry out corresponding Modulating Power and frequency range, accurately can determine the relative distance to each terminal accordingly further.
Further, the present invention also by the special mounting mode to access single point antenna or multiple antennas, as unobstructed installation, or installs block signal version additional, manually make the signal strength signal intensity of multiple antennas to other wifi terminals variant, thus accurately locate the relative distance to each terminal.
After accurately locating, in a certain wifi terminal near a certain access point or through particular path, the judgement that access point can be unique is near the terminal of access point.
Further, the signal strength signal intensity in the present invention is not limited to the signal strength signal intensity of wifi terminal, can also the signal strength signal intensity of comprehensive other technologies such as bluetooth or NFC carry out analyzing and locating.
Further, the present invention can also preset multiple access prescribed profile, and access authority corresponding multiple respectively, after terminal meets a certain access prescribed profile, access point corresponding to this terminal can authorize at access authority, as access intranet and extranet etc., and can adjust in real time.
Further, the present invention can also auxiliary detection is close by other means wifi terminal, such as light sensation, distance perspective should, time, collision, vibrations, gesture induction, ultrasonic wave, button etc.
With reference to figure 2, the wifi connected system of a kind of near field of the present invention authentication-exempt, comprising:

In the specific embodiment of the invention, wifi access point does not arrange password, and allow all terminal accesses, the terminal accessed first has initial rights, and is isolated in outside place of safety.In whole verification process, wifi terminal only needs shift position, does not need to install the operation of any software and hardware additional.
Be set in the present embodiment in vehicle-mounted, family expenses or the obvious occasion of food and drink this distance boundary, when entering indoor range, and access point straight line without hindrance every, can target customer be thought, such as passenger, household or client.
Specific embodiments of the invention are as follows:
1. access point focus is opened, and detects in scope and occurs new wifi terminal C.
2. the signal strength values of access point record C and MAC Address add list, because C just adds from edge, relative distance should be greater than the first distance threshold;
3.C is if target customer, and so he can gradually near focus, and signal meeting strengthen continuously, relative distance can be more and more less.Such as be less than second distance threshold value and the 3rd distance threshold gradually, arrive the 4th minimum distance threshold;
4. after relative distance is less than the 4th minimum distance threshold, C rests near access point, such as 3S, if the access prescribed profile of setting is that relative distance is less than the 4th minimum distance threshold, and wait for 2 seconds, then give the C connection authority preset according to condition;
Further, access point, can active adjustment its own transmission power or frequency hopping in judgement, and according to wifi feature, C can coordinate adjustment own power and frequency hopping, and access point uniquely can distinguish C accordingly.
Further, in vehicle-mounted, the scene such as family expenses or food and drink, same room with them is not through walls and have strong obstruct in outdoor, and signal strength signal intensity has obvious gap, and Strength Changes pattern also has difference, more accurately can judge targeted customer accordingly.
In actual applications, one can be pasted and illustrate near router, such as near surfing the Net.
From foregoing, wifi method of attachment and the system of a kind of near field of the present invention authentication-exempt draw relative distance by detection signal strength, thus draw corresponding connection authority according to the access authority condition judgment preset, avoiding illegally being utilized, while ensure that fail safe, significantly can simplify the identifying procedure that wifi connects, effectively shorten authenticated time.And the present invention realizes simply, do not need the upgrading carried out on any hardware to realize, effectively provide cost savings.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent distortion or replacement are all included in the application's claim limited range.
