Abstract
The invention discloses a kind of method that mobile terminal to being not connected with internet positions, including being not connected with the mobile terminal of internet, at least three WAP, wireless controller, and location-server；The described WIFI that mobile terminal comprises mobile terminal authentication information by its WIFI transmitter to each WAP unidirectional emission that states being not connected with internet keeps signal；The WIFI received holding signal is passed to location-server by wireless controller by each WAP；Location-server passes through mobile terminal authentication validation of information mobile terminal identity, and the WIFI received by each WAP keeps signal strength signal intensity and the signal step-out time of signal, positions this mobile terminal WIFI in real time.The present invention carries and on the basis of existing WIFI network, the mobile terminal being not connected with internet can be carried out unidirectional location.
Description
Technical field
The method that the present invention relates to the mobile terminal being not connected with internet is positioned.
Background technology
Real-time positioning system (WiFi RTLS) has had related application, and mobile terminal can pass through
WIFI network positions, but the location of mobile terminal needs it to tie up with WAP
Fixed, mobile terminal positions in the case of not binding WAP, there is presently no
Correlation technique.
Summary of the invention
It is an object of the invention to provide a kind of mobile terminal to being not connected with internet to carry out determining
The method of position, it can be on the basis of existing WIFI network, to the mobile end being not connected with internet
End carries out unidirectional location.
For achieving the above object, the technical scheme is that design is a kind of to being not connected with internet
Mobile terminal carry out the method that positions, including being not connected with the mobile terminal of internet, at least three
Individual WAP, wireless controller, and location-server；
The described mobile terminal of stating being not connected with internet wireless is connect to each by its WIFI transmitter
The WIFI that access point unidirectional emission comprises mobile terminal authentication information keeps signal；
The WIFI received holding signal is passed to by each WAP by wireless controller
Location-server；
Location-server passes through mobile terminal authentication validation of information mobile terminal identity, and leads to
When crossing signal strength signal intensity and the signal arrival of the WIFI holding signal that each WAP receives
Difference, positions in real time to this mobile terminal WIFI.
Preferably, described WIFI transmitter is launched WIFI with the frequency of 1Hz and is kept signal, launches
Power is 50-100 milliwatt.
Preferably, described WAP is anchor node.
Preferably, described mobile terminal is provided with WIFI holding signal frequency control module and WIFI
Keep signal strength signal intensity control module.
Preferably, described location-server is provided with mobile terminal authentication module and WIFI is real-time
Location Calculation module.
Preferably, described WIFI real-time location Calculation module includes that WIFI keeps signal frequency identification
Submodule, WIFI keep signal strength signal intensity identification submodule and WIFI to keep signal step-out time identification
Submodule.
Advantages of the present invention and having the beneficial effects that: a kind of movement to being not connected with internet is provided
Terminal carries out the method positioned, and it can be on the basis of existing WIFI network, to being not connected with interconnection
The mobile terminal of net carries out unidirectional location.And in position fixing process, mobile terminal need not bind nothing
Line access point.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is retouched further
State.Following example are only used for clearly illustrating technical scheme, and can not be with
This limits the scope of the invention.
The technical scheme that the present invention is embodied as is:
As it is shown in figure 1, a kind of method that mobile terminal 1 to being not connected with internet positions,
Including being not connected with the mobile terminal 1 of internet, at least three WAP 2, wireless controller
3, and location-server 4；
The described mobile terminal 1 stated being not connected with internet wireless is connect to each by its WIFI transmitter
The WIFI that access point 2 unidirectional emission comprises mobile terminal 1 authentication information keeps signal；
The WIFI received is kept signal to be transmitted by wireless controller 3 by each WAP 2
To location-server 4；
Location-server 4 confirms mobile terminal 1 identity by mobile terminal 1 authentication information,
And the WIFI received by each WAP 2 keeps the signal strength signal intensity of signal and signal to arrive
Reach the time difference, this mobile terminal 1WIFI is positioned in real time.
Described WIFI transmitter is launched WIFI with the frequency of 1Hz and is kept signal, launches power and is
50-100 milliwatt.
Described WAP 2 can be anchor node.
Described mobile terminal 1 is provided with WIFI and keeps signal frequency control module and WIFI to keep signal
Intensity control module.
Described location-server 4 is provided with mobile terminal 1 authentication module and WIFI positions in real time
Computing module.
Described WIFI real-time location Calculation module include WIFI keep signal frequency identification submodule,
WIFI keeps signal strength signal intensity identification submodule and WIFI to keep signal step-out time identification submodule.
The above is only the preferred embodiment of the present invention, it is noted that lead for this technology
For the those of ordinary skill in territory, on the premise of without departing from the technology of the present invention principle, it is also possible to
Making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
