Description

Based on Wi-Fi apart from acquisition methods, terminal, system, server and electronic equipment
Technical field
The present invention relates to wireless communication technology field more particularly to it is a kind of based on Wi-Fi apart from acquisition methods, terminal, System, server and electronic equipment.
Background technology
In LBS (Location Based Services, location based service) field, many application systems are both needed to Estimate the approximate distance between user by mobile terminal (such as cell phone apparatus), and then carries out the business such as friend-making, service recommendation Activity.Specifically, can be amusement and recreation type, service for life type, koinotropic type and business type by LBS points.The LBS of amusement and recreation type So that the user in same position region is participated in game, finds enjoyment；The LBS of service for life type is more It is various, including the dining room of finding nearby, hotel, market etc.；The LBS of koinotropic type is mainly to instigate the user in the same area can be with It is movable to be communicated and made friends etc.；The LBS of business type mainly believes the merchandise news of the location information of user and businessman, discount Breath etc. is combined, to promote customer consumption etc..
Obviously, all have to provide the positioning function of mobile terminal in above application, and the accuracy positioned is higher, it is fixed The means of position are more convenient, and the service that can be provided to the user will be abundanter.
Determine currently, location technology can be divided mainly into GPS (Global Position System, GPS) Position and non-GPS positioning.GPS positioning, technology relative maturity obtain the absolute seat of equipment in positioning means such as outdoor vehicle mounted guidances Mark, and then the distance between estimation apparatus.Rather than GPS positioning, such as：Based on the positioning means such as Wi-Fi, bluetooth, infrared, RFID The absolute coordinate of equipment, and then the distance between estimation apparatus are obtained, is also belonged to such；The second is the side based on point-to-point ranging Method.It can mutually be perceived by sensor i.e. between equipment and equipment, and then relative distance estimated by the power of perception.Such as Document CN104459612A, it is entitled to have measurement and WI-FI equipment distance and the mobile terminal of direction energy supply, be by Telemetry antenna and phase demodulation distance-finding module carry out the measurement of distance of mobile terminal and direction.The characteristics of such method, is to need Ranging both sides are limited in the range of sensor can perceive, and point-to-point direct perception is realized by sensor assembly.
However, becoming increasingly popular with the WLAN based on IEEE802.11b/g agreements, in all kinds of mobile terminals by Gradually start built-in wireless network card, in addition, the idea of development of " wireless city " is gradually moved to maturity by concept, is occurred in environment more next More AP (Access Point, wireless access point), these are all that the development of the location technology based on Wi-Fi creates facility Condition.
The location technology based on Wi-Fi occurred at present, there are two main classes：1) the positioning skill based on signal propagation model Art；2) it is based on the location technology of fingerprint (fingerprint) model.The former is when being propagated in air according to wireless signal The nonlinear attenuation characteristic revealed, establishes the model of signal strength and distance, to obtain location information.Since it mainly makes A series of location Calculation is carried out with the signal strength received, generally involves a large amount of calculating, it is still complex；More Importantly, due to which indoor environment complicated and changeable causes larger loss to the propagation of signal, and deposited in signal communication process In multipath effect, therefore the positioning result precision of this method is not high.And location technology of the latter based on Fingerprint Model, then mainly It is to realize positioning based on a large amount of actual observation data.The above method compared to the location technology based on signal propagation model, although The precision of positioning can be promoted, still, off-line training step needs take a substantial amount of time, manpower and material resources carry out calibration work Make, previous work is more heavy.
Invention content
In view of this, the embodiment of the present invention provide it is a kind of based on Wi-Fi apart from acquisition methods, system, server and one Kind of electronic equipment, it is high to solve to be based on Wi-Fi positioning accuracies in the prior art, and spends human and material resources that cost is higher to ask Topic.
