Description
Technical field
The utility model relates to field, relates in particular to a kind of indoor locating system based on WIFI.
Background technology
Positional information is being played the part of important effect in daily life.In the foreign environments such as countryside, exhibition center, park, use locating navigation information to can be spectators' visit service is more easily provided; In warehouse logistics process, article are carried out to real time location tracking and will greatly increase work efficiency; In environment, grasp timely and accurately related personnel's positional information at the prison, contribute to improve safety management level, simplify prison administration work.
Global positioning system (GPS) is the most common way of obtaining outdoor environment positional information at present.In recent years, along with the fast development of wireless mobile telecommunication technology, the A-GPS locate mode that GPS and cellular network combine has obtained gradually application in emergency relief and various position-based service (LBS).But block because satellite-signal is easily subject to various barriers, the satellite positioning tech such as GPS/APGS are not also suitable for indoor or built-up occasion, wireless indoor location technology develops rapidly at present, has become the strong of GPS and has supplemented.
In general, use wireless signal strength obtains the process of target position information, sets up exactly the process of wireless signal strength and positional information stable mapping relation.That existing indoor wireless locating system mainly adopts is infrared, ultrasonic wave, bluetooth, the short distance wireless technical such as WIFI, RFID.Wherein the wireless location technology based on WIFI network, because deployment is extensive and low cost is lower, therefore receives much concern.The RADAR system of wherein being developed by Microsoft is the navigation system based on WIFI network the earliest.It adopts radio-frequency fingerprint matching process, searches an immediate K neighbour from fingerprint base, gets on average estimating as coordinate of their coordinates.The statistical property based on RSSI signal of indoor locating system that document [5] is introduced, adopts Bayesian formula, distributes by the posterior probability of calculated target positions, positions.
This patent is equally based on WIFI network, Design and implementation a kind of wireless indoor navigation system, but different from above-mentioned localization method, this patent has adopted the location algorithm based on Weight selected, reduce to a certain extent the position error that RSS. signal change at random causes, experimental result shows, this system can obtain good positioning precision (4 meters).
Utility model content
For the problems referred to above, the utility model provides a kind of and can be mobile terminal client the indoor locating system based on WIFI of positioning service is provided at application scenarioss such as museum, market, campuses.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of indoor locating system based on WIFI, comprise service end and client, service end is mainly responsible for the Location Request of location Calculation and response terminal, described service end adopts the http protocol of standard to be connected with client communication, programming is convenient, extensibility is good, client-side program function can expand as required, described service end is by database, the Web server of response position request, the location-server of operation location Calculation and router composition, database, Web server, location-server and router interconnect by local area network (LAN), the Web server of response position request separates with the location-server of operation location Calculation, client and Web server adopt identical data exchange ways.
Further, described client comprises the mobile terminals such as computer PC, notebook, mobile phone, panel computer.
From the above-mentioned description to the utility model structure, compared to the prior art, the utlity model has following advantage:
The utility model can be mobile terminal client and provides positioning service at application scenarioss such as museum, market, campuses, consider mobile terminal and be subject to many restrictions such as computing capability, memory capacity and battery electric quantity, only complete simple signals collecting work, location Calculation is completed by positioning service end, its location is more accurate, and can, according to user's needs, carry out relevant application extension.
