It is not only easy however, being positioned using current localization method to indoor occupant, object by indoor complicated ring
The influence in border, position stability is poor, and overall cost is high.
As a result, it is necessary to propose that it is small that one kind is affected by the external environment, the high solution of positioning accuracy.And it is indoor at present
Pseudolite positioning cost is high, and Wi-Fi location technology is one of indoor positioning technologies, refers to through wireless access point (including nothing
Line router) composition Wireless LAN (WLAN), positioning, monitoring and the tracking task in complex environment may be implemented.It
Based on the location information of network node (wireless access point) and premise, combined using experience test and signal propagation model
Mode, position positioning is carried out to the mobile device that has accessed, highest accuracy is about between 1 meter to 20 meters.If positioning
Measuring and calculating is based only upon the Wi-Fi access point currently connected, rather than referring to the signal strength composite diagram of periphery Wi-Fi, then Wi-Fi is fixed
Position is just easy to that there are error (such as: positioning floor mistake).In addition, Wi-Fi access point usually all can only be 90 meters of covering radius
The region of left and right, and it is highly susceptible to the interference of other signals, to influence its precision, the energy consumption of locator is also higher.It is blue
The current utilization rate of tooth positioning is not high, this just needs a kind of novel positioning method to solve the above problems.
Summary of the invention
