Description
Technical field
The present invention relates to a kind of intelligent reverse vehicle searching system positioned based on wireless senser and radio signal.
Background technology
At present, newly-built parking lot is increasing, and car is parked in parking lot by user, when finishing thing when returning to look for car
Always finding not remember where car is parked in already clearly, parking lot is excessive, inside find oneself car be one very
The thing wasted time and energy.In parking lot, most Route Guidance System such as dynamic information prompt plate etc. is all used to
Parking service is provided, does not also have the reverse vehicle searching system that accurately induction is provided of maturation.Existing one
A little reverse car seeking technology, when user enter parking lot pick up the car time, user is wall-mounted by build in parking lot
Inputting the board information of oneself in inquiry terminal, terminal accepts the vehicle position information in server, feeds back to user.
The parking space information of user's reading terminals, eventually finds the automobile of oneself.But this kind of method also merely provides vehicle
The positional information parked, does not carry out seeking the path navigation of car process, in terms of vehicle position information acquisition, existing
Device is detected by the video frequency car position on parking stall each in being arranged on parking lot, under detection terminal monitoring general
Parking stall image carries out real-time grasp shoot.Then parking stall measure terminal sends the parking stall image information photographed to multichannel
Video processor processes, and the information after processing the most at last is sent in the server set up carry out unifying pipe
Reason.Whole information access process need to use a lot of external equipment, and these equipment construction costs are high, safeguard loaded down with trivial details multiple
Miscellaneous.To provide real-time route navigation, accurately indoor positioning is requisite.In terms of indoor positioning,
Having a lot of scholar to discuss at present and utilize infrared location, WLAN positions, and RF identification positions, bluetooth location etc..
Although although current indoor positioning technologies scheme is various, but without occurring can solving indoor positioning very well
Alignment system and really can parking lot provide make customer satisfaction system location technology the most immature.For reverse car seeking
Difficult problem we illustrates a kind of intelligence based on wireless senser and radio signal location technology and reversely seeks
Car system, in order to solve the above-mentioned problem run in reverse car seeking.
Summary of the invention
In order to overcome the problem that existing parking system reverse car seeking is difficult, the invention provides a kind of novel intelligence
Reverse vehicle searching system.This system can facilitate cheap acquisition storing cycle positional information, and in reverse car seeking mistake
Journey provide accurate real-time route navigate.We combine inner part of parking lot road distribution situation simultaneously, it is proposed that
A kind of indoor positioning algorithms being applicable to parking lot.
The technical solution adopted in the present invention is: a kind of intelligence positioned based on wireless senser and radio signal
Reverse vehicle searching system, including reverse car seeking navigation system, radio base station system and mobile phone terminal, reverse car seeking
Navigation system is connected with radio base station system and mobile phone terminal respectively, reverse car seeking navigation system, including stopping
Service management center, it have recorded the parking space information in whole parking lot and the ID of each radio base station and position
Information, provides the geographical coordinate of parking stall, with the path planning for reverse car seeking when registration of vehicle position；
Radio base station system, including multiple radio base station compositions being laid in parking lot, each radio base station pair
Emission comprises the radio signal of this Base station ID information, positions for mobile phone terminal；Mobile phone terminal is surveyed
The signal intensity that the surrounding radio base stations that amount receives sends, by comparing what the different base station received sent
The intensity of signal, first selects the position of maximum that base station of the signal intensity that receives as the present position of user
Put, due to the particularity of inner part of parking lot layout, recycling triangle polyester fibre algorithm and known inner part of parking lot road
Position obtained in the previous step is modified by road, parking stall scattergram, and the point fallen location on parking stall all shifts to
Utilizing the localization method after this kind of improvement to provide on road to position the most accurately, then mobile phone terminal is again according to vehicle
Stand is automatically cooked up rational path and guides user to find the vehicle of oneself；Mobile phone terminal provides instead
To seeking path planning and the navigation Service of car, reverse car seeking navigation system by radio base station system constantly with
Mobile phone terminal communicates, and obtains the present position of user and then navigates reverse car seeking process, mobile phone terminal
Automatic reception surrounding radio signal, and pass through to calculate according to the signal intensity of received each radio base station
Method realizes real-time positioning, and path shows and reverse car seeking induction.
The present invention also has following technical characteristic: utilize bluetooth, NFC or wifi being arranged on each parking stall
Base station, record is parked in the unique identification information of the mobile phone terminal entrained by vehicle driver on parking stall, car owner
After proposing the request of reverse car seeking, reverse car seeking navigation system searches the unique identification information of coupling, thus obtains
Parking position information, feeds back to car owner.
The intelligent reverse vehicle searching system that invention provides has had the advantage that: this intelligence reverse vehicle searching system is set up and stopped
Service management center, it can record the parking stall address information in parking lot and each radio base station clearly
Address information, facilitates car owner to pick up the car, and saves manpower and cost；Radio signal strength is utilized to use " grappling
Position " technology combination algorithm correction, make it to be precisely located, mobile phone can show in real time user position and
The path planned, navigates for user.Radio base station incorporates parking stall measure module, not only can be used to anti-
Location during seeking car can also be used to detect whether each parking stall has car.Mobile phone and radio base station simultaneously
Lure except parking can be may be also used in addition to applying during reverse car seeking in conjunction with the location navigation service provided
During leading.Becoming present aspect at radio base station, used is all the market common element of technology maturation, becomes
This is cheap.When utilizing base station to combine mobile terminal parking software (such as mobile phone A PP, vehicle-mounted computer) navigation, user
Only need to open oneself mobile terminal, be not required to purchase again other hardware device.For parking lot management person,
Parking lot, after laying base station, is no longer necessary to put into other manpower and hard at aspects such as navigation, inductions substantially
Part cost.Radio base station volume is little, is easy to lay, when laying in existing parking lot, it is not necessary to car
Position carries out large-area excavation, without following the strictest geometry designs, is typically laid in each parking stall central authorities
With road both sides.This intelligence reverse vehicle searching system hardware puts into low, easy care.Have the nothing of comparative maturity at present
Line electricity base station patrol checking technology, facilitates the maintenance, repair in later stage.
